Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bridge block and a foam block device,

The present invention relates to a foam block for pouring concrete into a wall, which can be used to construct concrete for wall construction without having to form a separate mold at the time of construction of the building, To bridges and foam block devices for foam blocks for support.

Generally, in order to pour a concrete wall, a pair of formworks are installed so as to be spaced apart from each other, and reinforcing bars are installed between the formworks and concrete is laid. In this case, when the concrete is cured after the form is installed, the form must be removed. However, this process is very cumbersome and takes a lot of time and is costly and there is a high possibility of safety accidents when the form is installed or disassembled .

In addition, after the concrete wall is cured and the form is removed, additional insulation should be attached to the inner and outer sides of the concrete wall. Therefore, not only is the operation very troublesome, but also, when an adhesive is used for adhering the heat insulating material, environmental hormones are generated in the adhesive.

Accordingly, a method of constructing a concrete wall using a foam block structure has been developed and widely used.

The construction of the concrete wall using the above-described foam block structure includes a foam block as a main block stacked on both sides of a space to be a concrete wall, and a bridge for fixing the foam blocks.

Examples of the foam block and the bridge include a foam block structure disclosed in Korean Patent Registration No. 10-102973 (Prior Art 1).

Fig. 1 is a perspective view of a main block and a bridging bridge, which are foam blocks of the foam block structure disclosed in the above-mentioned prior art document 1. Fig. 2 is a plan view of the main block and the bridge of Fig. A side view of a main block and a bridge for indicating a combination of bridges.

As shown in FIGS. 1 to 3, the main block 10 is manufactured by molding a styrofoam (neopol) having excellent heat insulation and soundproofing function into a rectangular block shape. At this time, a cross-shaped protrusion 17 protruding upward is formed on the upper surface of the main block 10, and a cross recessed groove 18 engaging with the protrusion 17 is formed on the lower side, The main block 10 can be coupled with each other in the vertical direction and the lateral direction to constitute the indoor side panel 11 and the outdoor side panel 12 having a large plate shape.

On the upper and lower surfaces of the main block 10, a plurality of coupling grooves 13 are formed at predetermined depths to vertically separate both ends of the bridges 28 and 29 from each other. To this end, a vertical insertion groove 14 is formed in the vicinity of the main block 10, passing through the center of the coupling groove 13. The coupling groove 13 and the insertion groove 14 are formed in the main block 10 by means of a connecting groove 15 formed in the upper and lower surfaces. Therefore, both ends of the bridges 28 and 29 can be fixed by fitting the coupling grooves 13 in the vertical direction of the main block 10. A plurality of the coupling grooves 13 are formed along the main block 10 so as to be spaced apart from each other by a predetermined distance and the plurality of bridges 28 and 29 can be coupled to the main block 10.

As shown in FIG. 2, the main block 10 is formed with a noise prevention slot 16. The noise prevention slot 16 is formed by passing through the upper and lower surfaces of the main block 10 and forming a narrow gap extending in the longitudinal direction of the main block 10 to form a space in the inner main block 10 Thus, external noise can be prevented from being transmitted to the room.

The wall construction bridge 28 is formed by bending a metal wire having high strength and has an extension part 21 and a coupling part 21 integrally connected to both ends of the extension part 21 and inserted into the coupling groove 13, (22). At this time, the extension part 21 is formed in a straight rod shape, and the coupling part 22 bends both ends of the extension part 21 in the form of a rhomboid rim, and extends in a direction perpendicular to the extension part 21 . The extension portion 21 is arranged to face the central portion of the engagement portion 22 and is connected to the extension portion 21 by a connection portion 23 in the form of a memory. The connecting portion 23 is formed by fitting the wall mounting bridge 28 into the engaging groove 13 of the main block 10 in addition to the function of connecting the extending portion 21 to the central portion of the engaging portion 22 And is inserted into the insertion groove 14 and the connection groove 15 when the connection is made so as to fix the wall mounting bridge 28 so as not to be rotated.

The foam block structure of the prior art having the above-described structure is formed by being laminated on both sides of a space to be a concrete wall by a bridge 28 for wall construction, and then, by placing concrete between the main blocks 10, The wall is integrally applied.

However, the conventional foam block structure having the above-described structure has the problem that the insulation performance of the outdoor side is deteriorated because the main blocks 10 are formed to have the same thickness.

Further, since the main block 10 has no noise preventing function and no heat insulating function improving function other than the noise preventing slot 16, it is necessary to prevent noise and improve the heat insulating performance.

3, the main block 10 is formed such that the engaging grooves 13 into which the engaging portions 22 of the bridges 28 are inserted are formed at the upper and lower portions of the unit blocks constituting the main block 10 independently of each other Therefore, when the entire foam block structure is installed, two bridge connection operations are repeatedly performed. Therefore, in view of the workload of the concrete wall construction on the construction site, the amount of bridge connection work is increased.

In order to prevent the bridges 28 inserted in the main block 10 from rotating, the engaging portions 22 are connected to the connecting portions 22 on both sides, It has a complicated structure such as a rectangular ring shape, and it takes a lot of time and cost to manufacture the bridge.

Further, the bridge has a problem in that the horizontal reinforcing bar can not be fixed at an accurate position so as to provide the optimum rigidity of the building.

The outdoor side foam block and the indoor side foam block are integrally formed with a synthetic resin having a heat insulating property so that a lamination protrusion and a lamination recessed portion are formed on an upper surface and a bottom side surface layer projection and a bottom surface laminated recessed portion are formed on a bottom surface, Lt; / RTI >
Wherein the bridge slot comprises: an engaging slot formed so that the engaging portion is inserted vertically downward on an opposing face of the outdoor side foam block and the indoor side foam block; and an engaging portion slot formed in the central portion of the engaging portion slot, Wherein the outer side foam block and the indoor side foam block are formed in a vertical downward direction so as to cut off the opposite sides of the block and have an extension slot in which the extension portion is inserted without being hung and the bottom surface is shielded by a T- Block and the indoor side foam block at regular intervals along the length direction,
The outdoor foam block is formed with a plurality of air pipes which are vertically pucked at predetermined intervals so as to be shielded from the other surface of the upper surface or the lower surface,
The indoor side foam block is formed with an air slot in which the air is filled in the vertical direction at a predetermined interval so as to shield the other end of the upper surface or the bottom surface,
Wherein protruding portions protruding from the outer side foam block and the indoor side foam block are formed to extend from the upper portion to the lower portion so as to have a predetermined distance from both sides of the bridge slots, A foam block device for casting a wall.
The method of claim 6,
The heat generated by the lamination protrusions, the lamination recessed portions, the bottom surface lamination protrusions, and the bottom surface lamination recessed portion formed in the outdoor side foam block may be an integral multiple of the heat formed by the lamination protrusions, the laminate recessed portion, Wherein the outdoor side foam block is formed so as to have an integral multiple of the thickness of the indoor side foam block.
