BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a method for constructing a dry double floor joist constructed by forming a space with an existing foundation floor surface in various buildings such as apartment houses.
[0002]
[Prior art]
Japanese Laid-Open Patent Publication No. 2000-166309 is a dry double floor joist construction method constructed by forming a space between a square or rectangular floor panel and an existing base floor using unit support legs, and a joist unit used therefor There is.
[0003]
As shown in FIG. 15, the present invention has a joist member b having a predetermined length in which a groove a is formed in the lengthwise direction on one side surface, an elastic pedestal c at the lower end, and the upper portion of the joist member b. A joist unit d provided with at least one support leg i attached to be adjustable in the vertical direction is used, and an elastic adhesive e having an initial adhesive force and having elasticity even when cured is provided along the groove a of the joist member b. After the coating is applied to a predetermined thickness, the joist unit d is attached along the wall surface f, and the height level of the joist member b is finely adjusted as necessary to construct the floor panel g.
[0004]
Accordingly, the joist member b of the joist unit d is not in direct contact with the wall f, and an elastic adhesive e layer is interposed between them, which prevents the floor vibration from being transmitted to the wall. Since it functions as a barrier layer, floor impact sound can be effectively prevented from propagating to the walls and downstairs and adjacent rooms, and the floor impact sound blocking performance is excellent.
[0005]
In addition, the height level of the joist unit d can be finely adjusted even after being fixed by the elastic adhesive e, so that a uniform floor surface can be obtained and the workability can be greatly improved.
[0006]
[Problems to be solved by the invention]
However, as shown in FIG. 16, the floor panel g provided between the joist unit d and the unit support leg h is formed by compression-molding a chip material, and the fact is that most of the warp is generated. is there.
[0007]
Accordingly, when flooring is performed with the floor panel g, the height of the joist unit d is first adjusted, and the height of the unit support leg h is adjusted by a horizontal ruler with the height of the joist unit d as a reference. However, since the floor panel g is warped, when the weight is placed on the floor panel g to correct it horizontally, a force to lift the joist unit d is applied to the joist unit d. If fixed, an error occurs in the height of the joist unit d, and there is a problem that the height of the unit support leg h cannot be adjusted accurately.
[0008]
The joist unit d is fixed with the elastic adhesive e between the wall f and means for fixing when the wall surface height cannot be sufficiently obtained such as in a place where there is no wall or a wall. There is a problem that the joist unit d of the above mechanism cannot be used.
[0009]
Further, in the standardized joist unit d, the position of the support leg c that can be adjusted up and down is determined. Therefore, the position of the support leg i must be changed by the pipe passing under the floor. Then there is a problem that can not be handled.
[0010]
Therefore, in the present invention, in order to solve the above problems, a joist construction method is provided in which the joist unit is fixed between the floor surface and the height can be adjusted and the support legs can be freely moved. .
[0011]

[0034]
Since the floor panel support plate 8 is installed in a state of providing a gap with the wall B surface, it is possible to prevent the floor impact sound from being transmitted to the wall and propagating downstairs or adjacent rooms.
Further, by installing a sound insulation plate D such as rubber or urethane on the back of the rail 1, it is possible to prevent the impact sound from propagating to the floor surface A and to prevent the pedestal 6 below the unit support leg 5 that slides in the rail 1. By making it made of vibration rubber, it is possible to minimize the propagation of vibration and impact sound to the floor surface A.
[0035]
Further, when a step is provided in the middle of the floor as shown in FIGS. 13 and 14, the height position of the joist is lowered by the amount of the step. In such a case, a metal angle 16 can be provided on each floor panel support plate 8 or a combination of the unit support leg 5 and the kineta support plate 24 can be used. By fixing 5 to the floor surface A, an error in adjusting the height of the floor panel support plate 8 due to warpage of the floor panel C can be eliminated.
[0036]
Further, since the unit support leg 5 is slidable left and right on the rail 1, the unit support leg 5 can be easily moved even when movement of the unit support leg 5 is required by a pipe piped on the floor surface A. Is.
[0037]
【The invention's effect】
As described above, according to the present invention, the floor panel support plate of the joist unit is not in direct contact with the wall, and in order to prevent the floor vibration from being transmitted to the wall, floor impact sound is not generated. It is possible to effectively prevent propagation to the walls and downstairs and to the next room, and the floor impact sound blocking performance is excellent.
[0038]
Also, the unit support legs can be slidable to the left and right with respect to the floor surface by rails and can be fixed, and the floor panel work can be done very quickly by combining with metal angle, kineta material or kiwana support plate. In addition, when the level is adjusted, the level can be adjusted with high accuracy without floating due to warping of the floor panel.
[0039]
In addition, by fixing the unit support legs on the floor surface, it is possible to perform construction even in places where walls are low or in places where there are no walls as in the case of construction methods in which joist members are fixed to the wall surface as in the past. In addition, since the unit support legs can be slid, it is possible to sufficiently cope with the case where the movement is unavoidable due to the construction status of the floor panel or the piping of the pipes.
