The present invention relates to a concrete foam panel used in the construction of a concrete structure, in particular, can be recycled, concrete weight panel is made to be easy to work while reducing the weight of the self and easy to assemble, the labor load of the operator is convenient It is about.

As is well known, concrete foam panels (often formwork) are assembled to partition an arbitrary space, and concrete structures are created by filling and curing concrete in any of these partitioned spaces. Due to the disadvantages that are used but not recycled, resin foam panels have been developed and used in recent years.

The resin-based concrete foam panel is generally a glass-fibre metreinforced thermoplastic (GMT) type concrete foam panel, and such a GMT type concrete foam panel is shown in FIGS. 7 and 8.

7 is a view showing an example of a concrete foam panel according to the prior art, showing a GMT-type concrete foam panel used when placing concrete such as floor or ceiling bar (A) is the front, (B) is Indicates the back side.

According to this, the floor or ceiling GMT-type concrete foam panel 100 is integrally molded by a GMT injection method using a common resin material, the front surface 110 is a relatively smooth surface, the rear surface 120 90 A plurality of vertical ribs 120b and horizontal ribs 120c intersecting the road and the edge 120a protrude rearwards.

8 is a view showing another example of a concrete foam panel according to the prior art, showing a GMT-type concrete foam panel used when placing concrete such as walls or columns, (A) is the front, (B) Indicates the rear face.

According to this, the GMT-type concrete foam panel 200 for walls or pillars is integrally molded by GMT injection method using general resins, the front surface 210 is aesthetically smooth surface, and the rear surface 220 A plurality of vertical ribs 220b and horizontal ribs 220c intersected by 90 degrees, and the edge 220a protrudes backwards, and the U-shaped groove 210a is formed at predetermined intervals along the circumference of the edge 220a, A reinforcing frame 221 consisting of a horizontal frame 221a and an edge frame 221b is attached to the rear surface 220.

On the other hand, since the concrete foam panel 100 shown in FIG. 7 is mounted horizontally on a frame such as rebar or wood installed horizontally, it is not necessary to connect each concrete foam panel 100 separately, but the concrete shown in FIG. Since the foam panel 200 is erected in a vertical state, in order to maintain a constant form, the concrete foam panels 200 must be fixed to each other by interconnecting each other through a separate connecting member.

9 is a rear view illustrating a connection state between the concrete foam panels shown in FIG. 8. Referring to the connection operation between the concrete foam panels 200 with reference to this, first, the respective concrete foam panels 200 are described. ) And after each other, by inserting the fastening plate 310 formed with the through-hole in the vertical direction in the longitudinal direction in the butt-closed groove (210a) by the edge (220a) of the concrete foam panel 200 and the border frame (221a) The through-hole formed in communication with) and the through-hole of the fastening plate 310 are arranged to communicate with each other, and the fitting portion 322 of the first pin member 320 is inserted into the through-hole communicated with one concrete foam panel The head part 321 of the first pin member 320 is brought into close contact with the edge frame 221a of the 200, and the fastening hole 323 of the first pin member 320 and the through hole of the horizontal frame 221b.

Since the GMT type concrete foam panels 100 and 200 can be reused by dismantling the connecting members 310, 320 and 330 after concrete pouring, they are advantageous compared to conventional wood concrete foam panels.

However, the GMT-type concrete foam panels 100 and 200 have to increase their thickness in order to maintain their strength sufficiently, and in particular, the GMT-type concrete foam panels 200 for walls or columns as shown in FIG. Since the reinforcing frame 221 is provided to maintain the strength, despite the resin material, the weight of the reinforcement is heavy, resulting in an increase in the labor load of the worker.

In order to solve this problem, when the material of the concrete foam panel is made of reinforced resin, the thickness of the concrete foam panel can be made thinner. However, the structure of the conventional concrete foam panel is difficult to expect to commercialize due to its large deformation. .

In addition, the GMT-type concrete foam panel 200 requires a plurality of connecting members 310, 320, and 330 used to interconnect the concrete foam panels 200, as shown in FIG. It became.

Accordingly, the present invention has been invented to solve the above problems, while providing a concrete foam panel that can be recycled, the self weight is greatly reduced and easy to assemble, so that the work load is convenient for the worker is lowered. Has its purpose.

As a cross-sectional view taken along line III-III, the concrete foam panel 10 shown therein shows that the overall shape is bent in a step shape, but the concrete foam panel according to the present invention is not limited to this embodiment and has a general "-" shape. Of course, it can be applied to concrete foam panels.

According to this, the concrete foam panel 10 according to the present embodiment, the overall shape is bent in a step shape is divided into the upper portion 11, the lower portion 12 and the connecting portion 13, these upper and lower portions (11, 12) And the front surfaces 11a, 12a, 13a of the connecting portion 13 are formed with a relatively smooth surface, and the rear surfaces 11b, 12b, 13b have a plurality of vertical ribs 15a, 15b, 15c, 15d, 15e that cross each other by 90 degrees. And 15f and the horizontal ribs 16a, 16b, and 16c, and the edge 14 are protruded rearward. Horizontal ribs 16c are disposed at equal intervals between the two vertical ribs 15a and 15f and the edge 14, and horizontal ribs 16a between the vertical ribs 15a, 15b, 15c, 15d, 15e and 15f. 16b are arranged at arbitrary intervals, and reinforcing ribs 19a, 19b are selectively disposed between the vertical ribs 15a, 15b, 15c, 15d, 15e, and 15f. In addition, the main gas supply line 17 is disposed in parallel with the horizontal ribs 16a, 16b, and 16c at an approximately center position of the entire longitudinal length, and the gas injection portion 17a of the main gas supply line 17 It is disposed at an approximately center position of the longitudinal length.
