Description

[Detailed Description of the Invention] The present invention relates to a fireproof and heat insulating support device for fixing a sandwich-type heat insulation panel to a structural member of a large refrigerator/freezer building.

The applicant previously proposed a fixture for supporting a heat insulation panel in Utility Model Application No. 55-123788, but the cap head is exposed on the panel surface, and if the synthetic resin heat shield is burned out, the panel supporting force will be reduced. This required additional work and drilling work to attach supporting fixtures to the panels. The present invention aims to eliminate the above-mentioned drawbacks, improve on-site workability, and further improve fire resistance and heat insulation performance.

Embodiments will be described in detail below with reference to the drawings. In Figures 1 to 3, the panel end 1' on the surface side constituting the outer wall of a building is shown in a Sanderutsch type insulation panel whose interior is filled with insulation material 6 and whose inner and outer skins are steel plates 1. An angle iron 2 is closely fixed to the inside corner of the steel plate 1 by welding or screwing. In addition to the angle iron, it may be an I-shaped steel or a shaped steel, and the location may be near the end of the panel instead of at a corner. The welding means may be corner welding or spot welding on the surface. Reference numeral 3 denotes a connecting bolt made of steel, with a collar 3a provided in the middle and a threaded portion 3b at the tip. and the base 3 of the connecting bolt 3
c is erected on the back surface of the angle iron 2 by welding.
The connecting bolt 3 is preferably made of nickel loam steel, which has the lowest thermal conductivity among metal materials.

Reference numeral 4 designates a heat insulating sleeve having a cross-sectional shape having a bolt through hole in the center, and is composed of a sleeve main body 4b having a flange at one end and a separate disc 4a.
A connecting cylinder 5, which will be described later, is then adiabatically clamped and fixed between the flange of the sleeve body and the disc 4a. The heat insulating sleeve 4 is made of ceramic or hard alloy resin for the purpose of securely fixing the steel connecting bolt 3 and the steel connecting cylinder 5 in a heat-insulating manner.

5 is a steel connecting tube with a flange 5 at one end.
a, and a head plate 5b having a through hole in the center is integrally formed on the head at the other end.

In this embodiment, phenol foam is filled as a heat insulating material between the inner and outer steel plates 1 and 1 of the Sanderuch type heat insulating panel, and an inorganic fire-resistant heat insulating material 12' is filled in the joints 12 between the panels.
The overlapping portions of the steel plates 1 and 1 are riveted into the inner and outer recesses 13 of the connecting portion, and a sealing material is filled with a backing material using a conventional method.

When shipped from the factory, the fireproof heat insulating support device according to the present invention connects the connecting cylinder 5 to the nut 7 through the heat insulating sleeve 4.
The heat insulating panel is closely fixed at the site, and after being transported to the site, it is attached to a cross member of a building (hereinafter simply referred to as a building) 10 via a bracket 8.

FIG. 4 is an exploded perspective view of a modification of the panel support device. In this case, the flange 5a of the connecting cylinder 5 and the bracket 8 are integrally formed, and the figure shows a longitudinal section thereof. The difference in FIG. 5 is that the means for fixing the connecting tube 5 to the building 10 is such that the heads 9a of round-head bolts 9 are screwed into female threads on the inner circumference of the connecting tube 5. In short, the means for connecting the steel connecting tube 5 and the building is not limited as long as it has fire resistance. The collar 3a of the bolt 3 provided in the middle of the connecting bolt 3 may be of any type as long as it can receive the heat insulating sleeve 4a. It can also be replaced with a nut screwed into the.

As described above, if the heat insulation panel is attached to the building 10 according to the present invention, the cap head will not be exposed on the panel surface as in the past, and the design will not be damaged. First, a steel section is fixed to the back side of the steel outer skin 1 of the panel, and a flange 3 is attached to the middle of the section.
A connecting rod 3 having a shape is fixed upright. On the other hand, on the building 10 side, the steel connecting tube is fixed to the building 10 via a steel bracket, etc., and the panel outer skin 1 is fixed to the building 10 through only the heat insulating sleeve 4a as a non-refractory material.
Since the structure is fixed, the heat insulation panel, which is secured to the connecting tube 5 with the connecting bolt 3, will not fall.

Furthermore, since the ends of the panel are made of strong angle iron, etc., there is a reinforcing effect against the bending of the panel.

Furthermore, when the building is being used as a constantly frozen and refrigerated warehouse, due to the difference in temperature between the inside and outside, the only heat flow path is the connection bolt 3 made of steel, which prevents heat loss and dew condensation on the panel surface. By filling the inside of the connecting cylinder 5 with a heat insulating material, heat radiation from the nut 7 can also be prevented. Furthermore, if the connecting bolts are made of nickel chrome steel as described above, the heat conduction can be reduced to one-third that of steel bolts.
