Description

[Detailed description of the invention] TECHNICAL FIELD This invention relates to a method for transversely extending insulation walls.

Conventional fiber reinforced cement board (hereinafter simply referred to as cement board)
A composite board assembly is constructed by connecting a plurality of composite boards in which heat insulating material is integrally laminated on the top and bottom, and this composite board assembly is also used as the front room frame, and this front formwork and rear formwork are connected to A method is already well known in which a concrete frame is formed by connecting the two forms with connecting rods at intervals and pouring concrete between the formworks, and then removing the rear room frame to construct a heat insulating wall.

However, in insulated walls constructed using this method, the composite plate may peel off from the concrete frame, and the outer ends of the connecting rods may be exposed to the surface of the composite plate, which is made of a good thermal conductor. As a result, the extra warmth from the outside air is directly transmitted to the inside of the wall, reducing the insulation effect.Furthermore, if the exposed outer end of the connecting rod is a composite board that also serves as a decorative board, the appearance may be damaged. There were drawbacks such as:

In order to eliminate these drawbacks, the devices shown in FIGS. 1 and 2 were provided. In what is shown here, in FIG. The first connecting rod 25 is separated from the second connecting rod 29, and a male thread is cut at both ends of the first connecting rod 25. A first threaded cylinder 2G with a flang is attached to one end of the connecting rod 25, and a second screw tube with a flang is attached to the other end. The threaded tubes 28 are screwed together, and one end of the M'tJ2 connecting rod 29 is screwed into the screw thread 28, and an inner and outer nut 30 is screwed into the other end of the connecting rod 29.
The rear heating frame 31 is connected as usual.

Note that 21 represents a composite board assembly, 23 represents a heat insulating material, and 24 represents a cement board.

Once the concrete frame 32 has been formed as described above, the connecting rod 25 and threaded tube 26 are removed, and as shown in FIG. After tightening, remove the outer diameter nuts, remove the formwork 31, and fill the gaps between the peripheral ends of each composite plate 220 with joints as usual.

However, in such a construction method, the composite plate 2
2, it is necessary to provide four through holes 27 for inserting the connecting rods 25 in a small case, and as many as 6 to 8 holes in a large case.
It is time-consuming to manufacture the threaded rod 3, and it is not enough to simply remove the connecting rod 25 and screw 26 during the construction process.
3 must be screwed on, which reduces work efficiency, and furthermore, it is necessary to prepare a threaded rod 33 that does not spoil the appearance of the external wall surface formed by the composite board 22, which is a hassle. There were drawbacks such as.

This invention eliminates the disadvantages and eliminates the disadvantages of the conventional construction method, prevents a decrease in work efficiency, and makes it possible to prepare redundant substitute parts without sacrificing the advantages of the conventional construction method. The purpose is to provide a construction method that does not require

In order to achieve the above-mentioned object, the present invention provides a plurality of grooves parallel to the surface of a cement board on at least two circumferential edges, and a plurality of grooves are arranged so as to face each other. A connecting member having a gutter-shaped protrusion having a through hole in the middle of both side flanges, the flanges fit into the grooves, and the protrusions connect between adjacent circumferential ends of each composite plate. A first connecting rod having a transparent shell through the protruding part of the connecting member and having both ends protruding outside the composite plate, and a first connecting rod having one end on the first connecting rod. The composite plate assembly is connected to the formwork at a predetermined interval by a second connecting rod that is separably connected to the composite plate assembly, and concrete is poured between the composite plate assembly and the formwork to form a concrete frame. After that, the first connecting rod and the formwork are removed, and the gap between the peripheral ends of each composite plate is filled with a joint material.

Embodiments of the present invention will now be described with reference to FIGS. Here, the same parts as those of the conventional one are given the same reference numerals, and the description thereof will be omitted.

FIG. 3 shows a composite board 1, which consists of a foam insulation material 2 and a glass fiber-reinforced cement board 3, which are integrally laminated with each other, and the insulation material 2 may be non-foamed. Also, the fibers do not have to be glass fibers. The cement board 8 is provided with a thick wall portion 5 at the left and right peripheral ends in the drawing, and a concave groove 4 is provided in the thick wall portion 5 in parallel with the surface of the cement board 30.
This is provided. In this case, the thick interior 5 may also be provided at the upper and lower circumferential ends, and a groove may be provided at the entire circumferential end.

FIG. 4 shows a connecting member 6 that connects the composite plate l and the lower plate, and is provided with a gutter-shaped protrusion 10 having a through hole of 8.9 mm in the middle of the flat plate-shaped flanges 7 on both sides. , the through hole 8 has a bent portion 1 whose both ends are bent at approximately 90° toward the same direction.
2.13 is inserted, one bent part 13 is supported on both sides by the top wall of the protruding part 10 and the folded part 14 of the one side flange part 7, and the through hole 9 is inserted into the first Connecting rod 25 is a through hole for the shell through hole.

FIG. 5 is a schematic diagram of a composite plate assembly weight 〇 using each of the members 1 and 6 as described above, and this assembly 16 is
After the grooves 4 of each composite plate 1 are arranged in parallel so as to face each other, the flange 7 of the connecting member 6 is fitted into the groove 4 to connect the plywood 1 on both sides.

Six different parts of the embodiment are shown in FIGS. 6 to 8 in the same condition as in FIG. 1, except that the composite plate assembly 16j' constructed in this way is used to construct an insulating wall. However, the rear formwork is omitted.

As shown in FIG. 6, the assembly 16 is connected to a formwork (not shown) using connecting rods similar to conventional ones, and concrete is poured between the two to form a concrete frame 32. At this time, the condition of the anchor member 110 portion is shown in FIG. 7, and the condition of the other portions is shown in FIG. It consists of a heat insulating material with a single-sided adhesive tape attached to it, and this tape eliminates missing parts of the heat insulating material. 18 indicates the backing plate.

After doing the above, connect the connecting rod 25, threaded cylinder 26, and backing plate 1.
8 and the rear formwork are removed, and the gap between the peripheral edges of the composite plate 10 formed by the protrusion 10 of the connecting member 6 is filled with a joint sealant (not shown) to complete the heat insulating wall.

In the case of bσ, depending on the size of the composite plate 1, a very small number of connecting rods may be provided outside the peripheral edge as in the conventional case.

The present invention is as described above, and a composite plate assembly is produced by connecting composite plates each having a concave groove on the peripheral end of the cement plate using a connecting member having flanges Z on both sides that fit into the concave grooves. Since one of the composite boards does not collapse or wobble during work, the safety of the cutting is increased, and a connecting rod can be inserted into this using the through hole pressed into the connecting member. There is no need to provide through holes for the introduction of connecting rods in the composite board itself, and even if they are provided, only a very small number of holes are required, which not only reduces the risk of damaging the appearance, but also reduces work efficiency and prevents fires. Furthermore, the protrusions of the connecting members form joints of uniform width, which has the effect of making the appearance more orderly.
