Description

[Detailed description of the invention] This invention is a heat insulating panel used for the ceiling, floor, or wall of so-called clean rooms such as operating rooms, food processing rooms, and precision equipment processing rooms, prefabricated refrigerators, and warehouses. This invention relates to a bonding structure for noncombustible panels such as fireproof panels.

Generally, this type of panel consists of a pair of face plates made of aluminum or steel, for example, and a foam insulation material or non-combustible or fire-resistant core material is filled between them.
Both panels are joined by engaging the core materials of both panels to be joined together with a binding material. However, as mentioned above, since the core material is a foam, it is relatively brittle and easily deformed, which may result in unstable engagement of the binding material or difficulty in positioning both panels. There was a problem.

This invention was made with the intention of solving the above problem, and it is possible to visually check the locking protrusion for preventing slipping off, which reliably engages with the core material of both panels to be joined, and the state of engagement with the core material. The object of the present invention is to provide a joining structure for noncombustible panels, etc., which is characterized in that panels can be easily and reliably joined using a joining material having positioning ridges.

Examples of this invention will be described below based on the drawings.

FIG. 1 shows a first embodiment of the joint structure of this invention, in which the panels 1, 1 to be joined are each made of a pair of metal surface plates 2, 2 made of aluminum, for example.
It is a noncombustible panel that is filled with a core material 3 in which asbestos and calcium carbonate are bound with vinyl chloride, for example, in between. The front plates 2, 2 are bonded to the back surface.
In addition, as the core material 3 of this noncombustible panel 1, for example, a heat insulating core material such as polyurethane may be foamed and filled between the surface plates 2, 2. A concave groove 4 into which a bonding material 5, which will be described later, is fitted is formed in the core material 2 on the bonding side end surface of the panel 1 constructed in this way. Then, after fitting the bonding material 5 into the grooves 4, 4 of the core materials 3, 3 of the adjacent panels 1, 1, and bonding both the panels 1, 1, the surface plate 2 of both the panels 1, 1 , 2 by sealing caulking material 6 between them, both panels 1, 1 are joined together.

As shown in FIG. 2, the bonding material 5 has serrated holes that can be engaged in the grooves 4 on the front and back surfaces of both sides of a plate-like main body 5b having a longitudinally extending hollow portion 5a. A plurality of locking strips 5c are provided protrudingly, and a positioning strip 5d is provided on the front and back surfaces of the central portion.
It is a structure formed by forming, for example, an aluminum profile. And the panels 1, 1
When joining, it is interposed between both panels 1, 1,
While watching the positioning protrusion 5d, fit the both sides into the grooves 4, 4 of both panels 1, 1, and engage the retaining strip 5c into the groove 4, and then remove both panels 1. , 1 can be reliably connected.

Figure 3 shows a second embodiment of this invention.
This is a case in which the positioning of both panels 1, 1 can be performed more accurately. That is, two flanges 5e, 5e which are parallel to each other are protruded from the front and back surfaces of the central part of the binding material 5 to form positioning ridges, and the panels 1, 1 are formed on the outer surfaces of both flanges 5e, 5e. By bringing the panels into contact with each other, both panels 1, 1
This is a case where the positioning can be performed accurately.

Figure 4 shows the third embodiment of this invention.
This is a case in which consideration is given to accurate positioning of both panels 1, 1 and improvement of the sealing performance of the caulking material 6. That is, a cross-sectional hollow protrusion 5f for positioning is formed on the front and back surfaces of the central part of the binding material 5, and both side surfaces 5g, 5g of the hollow protrusion 5f are brought into contact with the end surfaces of the panels 1, 1, respectively. The top surface 5h of the hollow protrusion 5f is used for accurate positioning.
is designed to also serve as a backup material for the caulking material 6.

In the second and third embodiments, other structures are the same as those in the first embodiment, so the same parts are given the same reference numerals and the explanation thereof will be omitted. Also, by utilizing the hollow part 5a of the binding material 5 that is commonly used in the first, second, and third implementations,
If the hollow portion 5a is filled with a refractory material such as calcium silicate or a refractory member 7 such as refractory granules, the non-flammability and fire resistance can be improved.

In addition, in order to create a fire-resistant panel, a calcium silicate layer is formed on the back side of the iron face plate, and a phenolic resin core material is filled between both face plates to form a panel with excellent fire resistance. , and if the bonding material is formed of steel, this fire-resistant panel can be bonded in the same manner as described above, and moreover, sufficient fire-resistant performance can be obtained.

As explained above, according to the bonding structure of this invention, the bonding material fits into the groove provided in the core material on the bonding side end surface of the panels to be bonded, and the retainer engages in the groove. Since a locking strip is provided, it bites into the side wall of the concave groove of each core material.
It can be firmly and firmly bonded to the core material, which is relatively brittle, and does not easily come off. In addition, since a positioning protrusion is formed in the center of the binding material, it is possible to quickly and accurately position both panels while looking at or using this positioning protrusion. Since excellent effects such as the ability of the service protrusions to also serve as a back-up material for the sealing material can be obtained, their utility value is remarkable.
