Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building panel block used for an outer wall or an inner wall of a building and a method for forming a wire mesh used for the panel block.

[0002]

2. Description of the Related Art Conventionally, in order to manufacture a building panel block used for an outer wall or an inner wall of a building, in general, reinforcing bars are arranged in a lattice shape and each reinforcing bar is formed into a binding wire so as not to be displaced. Are united. Then, a mold is assembled on the outer circumference of the reinforcing bar, and after the assembly, concrete is placed in the mold.

[0003]

However, since the work of binding the above-mentioned reinforcing bars is performed manually by a worker using a hook, the work efficiency is extremely poor. Also, the reinforcing bars must be arranged at a prescribed pitch,
The work of arranging is done manually by workers, which also poses a problem of poor work efficiency. In particular, when the building panel block is curved, the reinforcing bars are also bent and formed corresponding to the bending, so that the binding work and the reinforcing work of them are difficult.

Therefore, the present invention has been made in order to solve the above-mentioned problems, and its purpose is to use a wire mesh instead of the reinforcing bars and eliminate the steps of binding and arranging the reinforcing bars. It is an object of the present invention to provide a method for manufacturing a wire mesh for a building panel block, which can be easily manufactured and in which a wire mesh can be easily formed even in a curved building panel block.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the first aspect of the present invention is to construct a frame from a mold steel,
The gist is that a wire mesh is stretched on the front side of the frame, a mounting portion such as a bolt is provided on the back side, and the wire mesh is embedded in concrete or a foam material.

In the second aspect of the invention, the wire mesh peripheral edge is formed into a channel shape, and the wire of the wire mesh located on one side in the front and back direction of the frame is bent and crosses the bent wire. The gist is to bend and form the wire mesh by making the pitch between the wire materials narrower than before bending.

[0007]

Therefore, according to the first aspect of the present invention, the wire nets are stretched over the frame and embedded in the concrete, whereby the work of binding and arranging the reinforcing bars can be omitted, and the manufacturing is easy. become. According to the second aspect of the invention, the wire mesh is formed in a channel shape around the wire mesh, and the wire material of the wire mesh is bent, and the pitch between other wire materials that cross the other wire material that is bent is narrower than that before bending. .. This makes the wire mesh easy to bend.

【Example】

(First Embodiment) A first embodiment in which the present invention is embodied in an outer wall of a building will be described below with reference to FIGS.

As shown in FIGS. 1 and 2, a panel block 1 made of concrete for construction is formed in a flat plate shape, and most of the inner surface of the panel block 1 is formed with a recess 1a. A plurality of exterior decorative tiles 2 are fixed to the outer surface of the panel block 1 and a part of the left and right side surfaces.
A wire mesh 3 having a mesh-like mesh is embedded in the panel block 1, and an outer peripheral edge of the wire mesh 3 is erected inward.
A is bent and formed. H-shaped steel 4 is welded in the wire mesh 3 in the panel block 1 so as to form a lattice shape in the vertical and horizontal directions. Then, the upper end surface of the H-shaped steel 4 is flush with the inner surface of the panel block 1, and the flange 4a and a part of the web 4b inside the H-shaped steel 4 are:
It is projected inward with respect to the recess 1a. As shown in FIG. 1, the flange 4a of the H-shaped steel 4 on the right side is tightened and fixed to the side surface of the steel frame pillar 7 of the building by an unillustrated bolt and nut via an angle 5 and a flat bar 6 as a mounting portion. There is.

Next, a method of manufacturing the panel block thus constructed will be described. First, as shown in FIG. 3, a plurality of decorative tiles 2 are provided on the entire inner bottom surface of a form 8 which is opened in the upper part and has a box-like shape and is assembled in advance to a predetermined size, or a part of the inner surface. Arrange. Next, the H-shaped steel 4 is connected by welding in a grid pattern in the front-rear, left-right direction,
It is placed on the wire net 3 and the two are connected by welding. After the connection, the outer peripheral edge of the wire net 3 is bent at about 90 ° so as to surround the outer periphery of the H-shaped steel 4 to form the outer peripheral wall 3a. After that, the wire netting 3 and the H-shaped steel 4 are housed in the mold 8 with a spacer (not shown) at a predetermined distance from the upper surface of the decorative tile 2. A block 9 made of wood or metal is fixed to the upper portion of each H-shaped steel 4 by a bolt (not shown). Then, concrete is poured into the mold 8 and cured for a predetermined time according to the compressive strength of the concrete.

As described above, in the panel block 1 of the first embodiment, unlike the conventional case, the wire net 3 is used instead of the reinforcing bar, so that the reinforcing bar binding work and the reinforcing bar work can be omitted. Therefore, the construction time can be shortened and the manufacturing can be easily performed.

(Second Embodiment) Next, a second embodiment will be described with reference to FIG. However, the same components as those in the above-described embodiment are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 4, the panel block 10 made of concrete is curved from the center to the right side,
Most of the inner surface of the panel block 10 has a recess 10a. A channel-shaped wire mesh 11 is embedded in the panel block 10, and the right side from the center of the wire mesh 11 is curved so as to have the same radius of curvature as the panel block 10. Wire mesh 11 in the panel block 10
The H-shaped steel 13 (only the vertical direction is shown) is welded to the inner surface of the above in the vertical and horizontal directions so as to form a lattice. Then, the upper end surface of the H-shaped steel 13 is flush with the inner surface of the panel block 10, and the flange 13a and a part of the web 13b inside the H-shaped steel 13 are projected inward with respect to the recess 10a. ing. In addition, although not shown, the H-shaped steel 13 in the left-right direction extends from the center to the right side of the panel block 1
It is curved so as to have the same radius of curvature as 0.

Next, a method of manufacturing the panel block 10 of the second embodiment will be described. For convenience of explanation, the inner side in FIG. 4 is the upper side and the outer side is the lower side. First, as shown in FIGS. 4 and 5, the outer peripheral wall 11 a of the wire net 11 in the curved portion of the panel block 10 is bent. At this time, the bar arrangement pitch in the vertical direction of the wire mesh 11 in the curved portion of the panel block 10 is narrower than the bar arrangement pitch of the outer peripheral wall 11a at the left end from the center of the panel block 10. And
In the curved portion of the panel block 10, the reinforcing bars that cross the vertical reinforcing bars are bent into a substantially U shape. Next, the H-shaped steels 13 are connected by welding so as to form a lattice,
It is placed on the wire net 11 and the two are connected by welding. After the connection, the wire net 11 and the H-shaped steel 13 are accommodated from the center to the right side in a curved box-shaped mold 12 with a spacer (not shown) at a predetermined distance from the inner surface of the mold 12. .. A block 9 made of wood or metal is fixed to the upper portion of each H-shaped steel 13 by a bolt or the like not shown. Then, concrete is poured into the mold 12 and cured for a predetermined time.

As described above, in the panel block 10 of the second embodiment, even if the panel block 10 is curved, the work of binding and arranging the reinforcing bars can be omitted as in the first embodiment. Since the bending of the wire net 11 is facilitated, the construction time can be shortened and the wire mesh 11 can be easily manufactured.
