6), which is constructed as shown in FIG. 8.9. Reference numeral 41 indicates a heat insulating composite board (hereinafter referred to as a composite board), and this composite board 41 is made by laminating a glass fiber reinforced cement board 43 (hereinafter referred to as a cement board) on a foamed heat insulating material 42 (hereinafter referred to as a heat insulating material). Composite board 41
A female screw thread 45 with a collar portion 44 embedded at one end is provided in an appropriate location such as a corner of the cylinder, and a through hole 46 for introducing a mounting rod that communicates with the open end of the female thread tube 45 is provided in the heat insulating material 42. The mounting rod 4 whose head 48 is T-shaped is inserted through the hole 46.
7 is introduced and its tip is screwed into the female threaded cylinder 45.

When using such a composite plate 41, as shown in FIG. It is connected to the formwork 50 by the connecting rod 51, the second connecting rod 52, the oak) 53, 54, the threaded tube with flange 55, and the nut 56, and the composite plate 41 is connected at the peripheral end of the sheath to connect the front part. Formwork is formed, then concrete is poured between both formworks,
After forming the concrete frame 57, nuts 54, 56
, the second connecting rod 52 and the formwork 50 are removed to obtain a heat insulating wall 58 in which the composite board 41 and the concrete frame 57 are combined.

[Problem that the invention seeks to solve]

By the way, in the composite board 41 as described above, when making the heat insulating wall 58, the head 48 side of the mounting rod 47 protrudes from the heat insulating material 42 and the front formwork and the rear formwork 50 are separated before concrete is poured. placed between. Therefore, when concrete is poured, the concrete is attached to the protruding mounting rod 47.
This applied a load in the vertical direction and weakened the bonding strength between the mounting rod 47 and the female threaded cylinder 45, and furthermore, the female threaded cylinder 45 and the cement plate 43, resulting in cracks in the composite plate 41. After being used for a heat insulating wall, there were problems such as increasing the risk of falling off from the concrete frame 57 when an external force is applied to the composite board 41.

This invention eliminates the above-mentioned problems of the conventional ones, maintains strong bonding strength between the mounting bracket (female thread tube) and the cement board, and eliminates the risk of cracking and falling off as described above. The present invention provides a heat insulating composite board that can be manufactured in small quantities.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention has a female thread and a leg portion extending outwardly at the end. Anchor 2 has an e-shaped mounting bracket, a male thread that engages with the female thread of this mounting bracket, and a locking protrusion is formed on the outer peripheral surface of the intermediate part, and the anchor bolt has a locking protrusion. a washer having a through-hole with which the edge of the hole locks and a claw piece facing one side is formed on the outer edge thereof, and one end side of the mounting bracket is a through-hole provided at an appropriate position in the foam insulation material. and is inserted into the female thread through the through hole,
The hole edge of the through hole of the washer is screwed into the male thread of the anchor bolt which is locked to the locking protrusion, and as a result of this screwing, the claw piece of the washer is exposed so as to bite into the heat insulating material, and The legs of the mounting bracket are embedded in a fiber-reinforced cement board.

〔Example〕

In Figs. 1 and 2, 1 is a composite board, and this composite board 1 is composed of a foamed heat insulating material 2 and a glass fiber reinforced cement board 3, which are integrally laminated with each other. Steel fiber or the like may also be used. Through holes 4 are provided at appropriate locations such as corners of the heat insulating material 2.

Reference numeral 5 denotes a mounting bracket having a pipe-shaped main body 6. One end side of the main body 6 of the mounting bracket 5 is formed into a small diameter portion 7 whose diameter is slightly reduced, and a female thread 8 is cut on the inner circumferential surface of the small diameter portion 7. has been done. Further, the peripheral wall on the other end side of the main body 6 is cut from the other end over a predetermined length, and has a plurality of stop/upper pieces 10 cut at a substantially right angle at every other position in the circumferential direction, and the stop horns 9 The pieces form a plurality of axially oriented legs 12 having adjacent notches 1lt. The tip edge of the leg piece 12 is formed into a slightly protruding claw portion 13 by bending outward or the like. This claw portion 13 may be bent inward. The nine pieces 10 of the strut horns may be cut and raised by making cuts on the outer surface and then being bent, or may be manufactured by press molding. Further, the stopper piece 10 may not be integrated with the main body 6, but may be once cut away and then fixed to the base of the notch 11 by welding or the like.

15 is the anchor bolt, this anchor 2 bolt has head 1
A locking protrusion 18 protruding outward is provided at a male thread 17 portion at an intermediate position between 6 and the tip. This locking protrusion 1
8 is usually formed by crushing with a press, but may be formed by other means. Reference numeral 20 denotes a washer, through which the external thread 17 can be inserted, and the locking protrusion 18 has a disk-shaped thin plate 22 with a center hole 21 into which the hole edge locks, and is slightly recessed on one side. The thin plate 22 is formed into a shape, and a large number of claw pieces 23 facing one side are arranged in series on the peripheral edge of the concave side of the thin plate 22. The anchor bolt 15 and washer 20 are then assembled into the composite plate 1 in which the mounting bracket 5 is embedded, as shown in FIG. That is, the male thread 17 of the anchor bolt 15, whose hole edge of the center hole 21 of the washer 20 has been previously engaged with the protrusion 18, is screwed into the female thread 8 of the mounting fitting 5 through the through hole 4 of the heat insulating material 2. As a result, the washer 20 is moved toward the heat insulating material 2 by the protrusion 18, and then the claw piece 2
3 bites into the heat insulating material 2, and the anchor 2 bolt 15 is supported in the middle of the heat insulating material 2 by the washer 20.

To manufacture the composite board 1 having the above-mentioned mounting fittings 5, as shown in FIG. After pushing the insulation material 2 until it hits the bottom surface, the insulation material 2 is placed on the uncured glass fiber-containing cement board 3 placed in the formwork 14, and the insulation material 2 is pressed from above by an appropriate means to insulate it. At the same time, the material 2 is crimped onto the cement board 3, and the mounting bracket 5 is attached.
The leg pieces 12 are buried in the cement board 3. In the above, since the mounting bracket 5 is first inserted into the through hole 4 and the stone 9 piece 10 is applied to the bottom surface of the heat insulating material 2, the installation position will not be changed if the mounting bracket 5 is tilted when suppressed. It is easily and accurately embedded into the cement board 3. After that, when the cement board 3 is cured, the heat insulating material 2 and the cement board 3 are integrally laminated, and a composite board 1 in which the mounting bracket 5 and the cement board 3 are firmly connected is obtained.

When using such a composite plate 1, as shown in FIGS. 1 and 4, as in the case of conventional hand necks, first attach the head to one end of the female thread 8 of the mounting bracket 5 embedded in the composite plate 1. The male thread 17 of the anchor 2 bolt 15 having the anchor 16 is screwed through the through hole 4 of the heat insulating material 20 so that the head 16 protrudes beyond the heat insulating material 2.

Next, connect the composite plate 1 to the first and second connecting rods 51, 52,
53, 54, 56, and the rear formwork 50 through the flanged threaded cylinder 55, the composite plates 1 are joined at their peripheral ends to form a front formwork, and the front formwork formed in this way is Reinforcing bars 49 are arranged vertically and horizontally between the part formwork and the rear formwork 50. Next, concrete is poured to form a concrete frame 57. After that, when the nuts) 54, 56, the second connecting rod 52, and the formwork 50 are removed, the composite plate 1 and the concrete frame 5 are removed.
A heat insulating wall in which 7 is firmly bonded is obtained.

When an external force is applied to the heat insulating wall, the composite board 1 is attached to the concrete frame 57 by the mounting brackets 5 and anchors 15.
In addition, the mounting bracket 5.0 leg piece 12 is embedded in the cement board 3 with just enough glass fiber injected around it, making the bonding strength extremely strong. The pulling force of the mounting bracket 5 acting on the concrete frame 57 can be made larger than the tensile force.
There is little risk of it falling out.

Furthermore, when pouring the concrete, if the concrete hits the anchor bolt 15 including the head 16 that protrudes beyond the heat insulating material 2, even if a vertical load is applied to bend the anchor bolt 15, the anchor Since the bolt 15 is supported in the middle by the claw washer 20, it can withstand the bending moment caused by the load, protects the bonding force of the embedded part of the mounting bracket 5, and strengthens the bonding strength between the mounting bracket 5 and the cement. maintain it.

5 to 7 show various modifications of the mounting bracket 5.

The mounting bracket 5a shown in FIG. 5 bulges out the peripheral wall of the other end of the main body 6a to form a bulging part having a shoulder 9&, and cuts the peripheral wall of the bulging part to form a leg piece 12m in which the notch 11a is inserted. A plurality of stopper members 10m are formed in the circumferential direction, and the center hole of the disk-shaped stopper member 10m is inserted into the main body 6a with the hole edge engaged with the shoulder portion 9a. The mounting bracket 5b in FIG. 6 is formed by cutting the other end wall of the main body 6b, and cutting and raising the base at right angles to form a plurality of straight horn portions 10b in the circumferential direction. A leg piece 12b is formed into which a notch 11b facing the axial direction is inserted from the tip of the stopper zm10b. The mounting bracket 5c in FIG. 7 bulges out the other end local wall of the main body 6& to form a bulge having a shoulder 9c, and cuts the circumferential wall of the bulge into every other wall in the circumferential direction. A stopper piece 10e is cut and raised at a substantially right angle, and a leg piece 12c having a notch 11e1 and facing in the axial direction is formed. 13a and 13b in each of the above modifications.

Reference numeral 13c is a mourning claw portion formed at the tips of the leg pieces 12m, 12b, and 12e by slightly bending them outward. Each of the above mounting brackets 5m
, 5b, 5c are the notches 11 between the leg pieces.

11b and llc can be made wider than that of the mounting bracket 5, which has the advantage that the pull-out strength with respect to cement is even greater.

In addition, in the above embodiment, the mounting brackets are 5.5 m long and 5 b long.

Although the one shown as 5c is taken as an example, it goes without saying that in the present invention, a mounting fitting having a flange such as a conventional female threaded cylinder may be used.

〔Effect of the invention〕

The present invention is as described above, and includes a locking protrusion anchor I.
Since the claw of the washer with the through hole that was locked on the locking protrusion of the bolt was inserted into the foam insulation material, the head side protruded from the foam insulation material when making the insulation wall. Even if a vertical load is applied to the anchor port by the concrete poured into it, the middle of the anchor bolt is supported by the washer and acts to resist the load, which increases the bond strength between the mounting bracket and the cement. It has the excellent effect of reducing the risk of cracks occurring in the composite board or of the composite board falling off after being used for insulation walls.
