The frame body 4 has left and right side frame bodies 11A, 11B and a plurality of beams 12A, 12B connecting the left and right side frame bodies 11A, 11B. In the present embodiment, the frame body 4 is divided into an upper frame body 4A, a middle frame body 4B, and a lower frame body 4C, and these frames are connected by connection parts C1 and C2, respectively. In order to form an inclination angle of approximately 30 degrees, inflection point portions Q1 and P1 for inclining downward are formed in the upper frame 4A, and inflection point portions for inclination upward are formed in the lower frame 4C. Q2, P2.

The side frames 11A and 11B constituting the frame 4 are formed of steel plates, and are formed in units of the upper frame 4A, the middle frame 4B, and the lower frame 4C, respectively. Specifically, the peripheral edge of the steel plate is bent in the same direction so that the cross-section is L-shaped, forming an upper side 11a to be the upper chord portion, a lower side 11b to be the lower chord portion, a connecting side 11c to be the connecting portion, and a The above-mentioned partly surrounds the side 11d of the side frame unit. In addition, since the side frame bodies 11A and 11B have the same structure, only the side frame body 11B will be described.

As shown in FIG. 4, the connection member 13 is installed in the side frame unit formed by the above method. Specifically, the connecting member 13 is arranged on the inner side surrounded by the upper side 11a and the connecting side 11c of the side frame unit, and its connecting surface consists of the upper connecting part 13a connected to the upper side 11a by bolts, and connected to the upper side 11a by bolts. A connection portion 13b connecting the side 11c and a side portion 13c connected to the side surface 11d by bolts are formed. In addition, the connecting member 13 provided on the inner side surrounded by the lower side 11b and the connecting side 11c of the side frame unit has a lower connecting portion 13d connected to the lower side 11b by bolts, and a connecting portion 13b connected to the connecting side 11c by bolts. And the side part 13c connected to the side 11d by a bolt. The connection members 13 are respectively connected to the side frame units with bolts, and thereafter, the side frame units formed in units of the upper frame body 4A, the middle frame body 4B, and the lower frame body 4C are connected to each other.

When performing the connecting work, the adjacent connecting edges 11C of the side frame units formed in units of the upper frame body 4A, the middle frame body 4B, and the lower frame body 4C are brought into contact with each other, and in this state, are connected with the connecting member 13. The adjacent connection sides 11c that are in contact with each other are clamped, and thereafter, in the state where the adjacent connection sides 11c are clamped, the bolts B are passed through the adjacent connection portions 13b to connect and connect. At this time, in order to prevent the upper side 11a and the lower side 11b of the adjacent side frame units from shifting in the up-down direction, positioning holes 13H are provided on the two opposite connecting members 13 and the two adjacent connecting sides 11c. The positioning pins 14 are inserted into the positioning holes 13H, and then the bolts B are used to connect them, thereby improving the assembly accuracy of the side frame bodies 11A and 11B.

On the left and right side frames 11A, 11B having the above-mentioned structure, the rail bracket 15 as a vertical member is fixed across the side 11d, the upper side 11a, and the lower side 11b by bolting. This rail bracket 15 is also formed by bending and forming a steel plate, and has an upper fixing portion 15a connected to the upper side 11a of the side frame unit by bolts, a lower fixing portion 15b connected to the lower side 11b by bolts, and a lower fixing portion 15b connected by bolts to the upper side 11a of the side frame unit. The side fixing part 15c connected to the side 11d. Moreover, relative to the side fixing portion 15c, a component mounting portion 15d protrudes toward the opposing side frame bodies 11A, 11B, and the component mounting portion 15d is provided with a mounting base for mounting and fixing each component. Specifically, the installation base 15A for the outbound side guide rail 16 for installing the running wheel 7W guiding the step 7, the installation base 15B, 15C for installing the return side guide rail 17A, 17B for guiding the running wheel 7W, and An installation base 15D for fixing the skirt guard 18 and the like.

And, the crossbeam 12A is connected by bolts to the middle part in the height direction of the guide rail brackets 15 on the left and right sides, that is, at the position facing the moving loci of the step 7 on the outbound side and the step 7 on the return side, and the crossbeam 12A is connected by bolts. By connecting the beam 12B to the lower end portion of the rail bracket 15 , it is possible to prevent the left and right side frames 11A and 11B from falling down, and to secure the rigidity of the frame 4 .

A plurality of beams 12A, 12B are arranged along the length direction of the frame body 4, and the oil storage pan OP is installed on the beam 12B located at the lower part, and its left and right parts are connected to the lower end of the guide rail bracket 15 by bolts. fixed.

According to the present embodiment as described above, the side frame bodies 11A, 11B, which are the constituent parts of the frame body 4, are not constituted by profiles, but the side frame units are formed by bending and forming steel plates, and further in the longitudinal direction. Since the side frame bodies 11A and 11B are configured by connecting the side frame units, the weight of the frame body 4 can be reduced.

Since the connection of the side frame units and the connection of each member are carried out by bolt fixing, for example, the guide rail bracket 15 and the side frame bodies 11A, 11B, etc. will not be deformed due to welding heat. When the positions of the bases 15A to 15D are adjusted, only a minimum adjustment is required, and the productivity of the housing 4 can be improved.

In addition, when the escalator 1 needs to be disassembled for remodeling, since there is no welded connection, it is only necessary to loosen and remove the fixing bolts, so that the dismantling of the frame body 4 becomes easier. More convenient.

In the above description, a total of two kinds of connecting members 13 are used, one is used to connect with the upper edge 11a of the side frame unit, and the other is used to connect with the lower edge 11b, but in order to reduce the number of parts, it is also possible to use such as The connection member 13A shown by the two-dot chain line in FIG. 4 is an integrated connection member in which the fixing surface is simultaneously connected to the four surfaces of the upper side 11a, the lower side 11b, the connecting side 11c, and the side surface 11d.

In addition, in the above description, the connecting parts C1 and C2 of the upper frame body 4A, the middle frame body 4B, and the lower frame body 4C, that is, the division positions, are respectively provided at the downwardly inclined end portion of the upper frame body 4A and at the bottom of the lower frame body 4C. The upwardly sloping ends may be divided at the bending points Q1 and P1 of the upper frame 4A and the bending points Q2 and P2 of the lower frame 4C as shown in FIG. 1 . By dividing at the above-mentioned position, there will be no curved portion, and the frame body can be divided into an upper horizontal section, a middle inclined section, and a lower horizontal section that are all linear, thereby improving the production efficiency of the frame body 4 and improving the quality of the frame body 4 after disassembly. transport efficiency, etc.

In addition, in the above description, weight reduction is realized by the above structure, but if further weight reduction is required, a triangular-shaped hole 19A shown by a dashed-two dotted line in FIG. 19B, 20A, 20B, so that the weight can be further reduced. When opening the holes 19A, 19B, 20A, 20B, it is important to avoid the portion of the side surface 11d where the guide bracket 15 is provided in order to prevent the strength of the side frames 11A, 11B from decreasing. Furthermore, by making the long sides of the triangular-shaped holes 19A, 19B, 20A, and 20B face each other and forming slopes 21 and 22 on the side surface 11d to form a truss shape, it is possible to prevent the rigidity of the side surface 11d from being lowered.

When the frame body 4 is deformed due to welding heat, and the installation positions of the components are displaced, the ones that are most likely to be affected by the welding heat to be displaced are the outbound side guide rail 16 and the return side guide rails 17A, 17B. Set location. When the installation positions of the outbound side guide rail 16 and the return side guide rails 17A, 17B deviate, the steps 7 cannot be guided stably with high precision, resulting in vibration and noise when the steps run. In addition, as shown in FIG. 1 , in the frame body 4 , the section where the steps 7 must be stably guided with high precision is located at the bending point parts Q1 and P1 of the upper frame body 4A and the bending point part Q2 of the lower frame body 4C. , the slope interval between P2. As long as members are not deformed by welding heat in this inclined section, it is possible to install the outbound side guide rail 16 and the return way side guide rails 17A, 17B with high precision. On the other hand, since the driving device 8 and the driving sprocket DS etc. are provided in the horizontal section extending from the bending point parts Q1 and P1 to the end portion side of the upper frame body 4A of the frame body 4, in addition, the lower frame body The driven sprocket FS is provided in the horizontal section extending from the bending points Q2 and P2 to the end portion side of 4C, and the driven sprocket FS is driven by winding the step chain 6 around the sprocket. The structure of the horizontal section is set as a structure with high rigidity.

For this purpose, in a frame 4 arranged on the building across the upper and lower floors and having an upper horizontal section and a middle inclined section as well as a lower horizontal section, the upper horizontal section and the lower horizontal section are carried out using profiles and fastened by bolts. Assembled to form a skeleton structure, on the other hand, the side frame body located in the middle inclined section of the frame body is formed by the side frame unit formed by the steel plate, and the bolts are used to connect the The skeleton structure of the upper horizontal section and the lower horizontal section and the intermediate inclined section composed of side frame units. According to the above structure, the middle inclined section is constructed so as not to deform and can realize a lightweight structure, while the upper horizontal section and the lower horizontal section are constructed so as not to deform and have high rigidity. In addition, when the floor height of the building is high, it is preferable to divide the intermediate slope section into a plurality of units in the longitudinal direction in consideration of production efficiency, transportation efficiency, and the like.

In the above-mentioned structure, the skeleton structures constituting the upper horizontal section and the lower horizontal section of the frame body 4 are configured to have inclined portions having the same inclination as that of the middle inclined section, so that the middle inclined section can be formed The shape of the steel plate of the side frame unit is formed into a simple shape of a quadrangle, which has the advantage that the bending of the steel plate becomes more convenient.

In the above-mentioned structure, the connection between the components of the framework structure of the upper horizontal section and the lower horizontal section, that is, the sections, is carried out by bolt fastening, but it is also possible to connect without bolt fastening, and by connecting a part of the connection part or All soldered to connect. This is because the profile of the frame structure has a larger heat capacity than the steel plate, and when connected by welding, there is only slight thermal deformation compared with the case of welding the steel plate, so the thermal deformation of the member is also small.

However, when the skeleton structure is constructed by welding the section materials, it is necessary to cut the welded part when performing dismantling work at the time of rebuilding. However, since only the upper horizontal section and the lower horizontal section are connected by welding, and the middle inclined section is connected by bolting, by using each section as a unit, for example, the upper horizontal section, the lower horizontal By disassembling the frame body 4 as a unit, troublesome cutting operations can be kept to a minimum.
