Description

[Detailed explanation of the invention] This invention installs fire-resistant insulation panels on external walls, internal walls, ceilings, etc. of refrigerated and frozen warehouses, etc., which require high-performance insulation, fire prevention, and fire resistance. It relates to a fixture for fixing.

Nowadays, many foods are distributed through refrigeration and freezing processes, and there is extremely strong demand for large-scale refrigerated and frozen warehouses.

Although the thermal insulation performance of the insulation panels that make up these external walls has improved, it is difficult to install and fix the insulation panels.
However, due to the difference in temperature between the inside and outside, heat leakage occurs, reducing refrigeration efficiency, and condensation on the outer surface of the panel, resulting in corrosion and deterioration.

In addition, as a support structure for panels in areas where fireproof construction is required, a system was developed in which fireproof and insulated panels are fixed with Pol I via resin seats, as in the earlier application No. 75607. However, subsequent research has shown that in the event of a fire, the panel body may come loose from the bolts and collapse and fall to the outside of the refrigerator, making it insufficient as a fireproof structure. Became.

The present invention eliminates each of the above-mentioned drawbacks, and is particularly suitable as a fixture for attaching and fixing heat insulating panels used in fireproof refrigerated warehouses constructed in fire prevention areas.

Examples will be described in detail below with reference to the drawings.

FIG. 1 is a cross-sectional view of a fireproof insulation panel 2 supported by a fixture 1 of the present invention and fixed to a building 8 via a bracket 3 by tightening a nut 4.

The fixture 1 is composed of three parts: a large-diameter cylindrical cap 5, a heat shield 6 continuous to the cap, and a bolt 7 built into the cap.

In the figure, 5a is a disk-shaped cap head exposed to the outside, and 5b is a circular locking wall located near the other end of the cap.

The locking wall 5b has a through hole in its center, through which the port I-7 passes and the port I/head 7a is housed in the cap 5.

As described above, the cap 5 is hollow, and in this embodiment,
The cap head 5a is manufactured by welding the locking wall 5b, inserting the bolt 7 into the through hole in the center so that the bolt head 7a is built in, and then welding the cap head 5a.

The heat shield 6 is a cylindrical body made of hard synthetic resin with as low a thermal conductivity as possible, and the pole 1-7 is passed through the shaft center of the heat shield 6, and there is a female hole on the indoor side to be screwed into the body. It has a through hole with a threaded portion 6b attached thereto.

The end surface of the heat shield 6 in contact with the cap 5 is integrally provided with a tubular sleeve 6a having a shape t7. as a seat for supporting the bolt head 7a.
As will be described later, this prevents the metal cap 5 and the steel bolt 7 from coming into contact with each other and significantly reduces heat transfer in this area.

Further, the heat shield 6 and the cap 5 are integrated with a strong adhesive at their contacting peripheries.

In addition to this integration using adhesive, a synthetic resin washer may be interposed between the locking wall 5b and the bolt head 7a.

The bolt head 7a is built into the hollow part of the cap 5, and the male threaded part 7b on the opposite side is connected to the female threaded part 6b of the heat shield 6. It is screwed together and protrudes from the panel body toward the indoor side.

As explained above, in the present fixing device 1, the three parts of the cap 5, the heat shield 6, and the bolt 7 are integrated and do not separate from each other, and the nut 4 is usually screwed onto the bolt 7. It is advantageous because there is no fear of loss during storage and transportation.

The overall length of the cap 5 and the heat shield 6 in the longitudinal direction is the same as the thickness of the panel 2 to be fixed, and their outer diameter is a constant size of a cylinder. It is only necessary to open a hole of a fixed size.

Next, to explain the installation, insert the proposed fixing device 1 into the insertion hole of the panel 2 to be fixed, which has an insertion hole drilled in the appropriate place, so that the cap head 5a is in contact with the outdoor surface of the panel 2 to be fixed, and then Pre-built the tip of bolt 7 protruding from e78
Pass the washer 4a through the hole of the bracket 3 fixed to the
It is only necessary to tighten the nut 4 through the nut 4.

In order to prevent the cap 5 and the bolt 7 from coming into contact with each other, the length of the tubular sleeve 6a of the heat shield 6 must be greater than the distance from the indoor end of the locking wall 5b of the cap 5. be.

When the panel is attached and fixed to a building using the fixing device of the present invention, during normal use it exhibits the same function as the conventional synthetic resin insulation pole 1.

Moreover, even if a fire breaks out nearby, the bolt head 7a locks the locking wall 5b, and the outer side of the panel is restricted by the cap head 5a, so the panel is supported by the cap 5 and the bolt 7, and the building 8 is maintained.

Therefore, the panel does not fall and collapse, and it is possible to prevent the panel from catching fire due to the intrusion of flames.

Particularly in areas regulated as semi-fire prevention districts or above, metal panel surface plates 9,
Between 9 and 10, high-performance heat insulating material polyurethane 10 is placed in the center.
If a fireproof heat insulating panel with a non-combustible heat insulating material such as calcium silicate plate 11, 11 arranged on both sides is adopted, an extremely excellent effect as a fireproof structure can be achieved.

Fig. 2 shows a different embodiment of the fixing device according to the present invention, in which the cap 5
On the indoor side of the cap 5, an extension part 5C with a screw attached to the inner periphery is formed to be screwed together with the heat shield 6, and on the outdoor side of the cap 5, a separate cap head 5a' is screwed together. This eliminates the welding work involved in assembling the proposed fixture.
