Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure for fireproof roof panels, and more particularly, to a pair of surface plates, frame members and core members each formed of an aluminum member. TECHNICAL FIELD The present invention relates to a fire-resistant roof panel connecting structure for connecting fire-resistant roof panels to each other.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 15, an aluminum core material 2 is interposed between a pair of aluminum face plates 1 and both face plates 1, as shown in FIG. Is known in which a hollow frame member 3 made of aluminum is interposed between the sides of the aluminum plate and the surface plate 1, the core member 2 and the frame member 3 are integrally brazed or bonded.

[0003] The fire-resistant roof panel thus formed has a predetermined strength, but when exposed to a high temperature due to a fire, the panel is bent in the longitudinal direction and deformed. And the strength of the roof may be reduced. Conventionally, as a means for solving this problem, as shown in FIG. 15, two steps of recesses 4a and 4b are provided on the outer surface of the frame member 3, and a sealing member such as a silicone sponge rubber is provided on the upper step of the recess 4a. A seal packing 5 made of stainless steel is fitted, the two panels are joined so that these seal packings 5 come into close contact with each other, and a fire-resistant plate 6 made of a material having excellent fire resistance, for example, stainless steel, is inserted into the lower groove 4b. The two panels are connected to each other by fixing them to the side of the body part that does not have the fixing members 7 such as bolts and nuts (see FIG. 16). A channel-shaped reinforcing member 8 is fitted in the hollow portion of the frame member 3, and a refractory seal 9 is filled in the upper side of the gap between the connecting portions of the panels.

According to the panel connecting structure constructed as described above, when exposed to a high temperature by a fire, the fireproof plate 6
This can prevent the fire from spreading upward.

[0005]

However, since the conventional connecting structure is a structure in which the refractory plate 6 is simply inserted into the lower groove 4b provided in the frame member 3, it is exposed to high temperature by a fire. When the panel is bent and deformed, a gap (joint) between the connecting portions of the panel is opened, and a gap is generated between the refractory plate 6 and the frame member 3, so that the flame turns upward. There was a problem. As a solution to this problem,
A method of making the frame material 3 solid or increasing the thickness of the refractory plate 6 and the panel itself can be considered. However, such a structure increases the weight of the entire panel and impairs the weight reduction of the panel. There was a problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a connecting structure for a fireproof roof panel which is lightweight and capable of maintaining the fire resistance of a connecting portion due to deformation under high temperature.

As described above, since the present invention is configured as described above, the following effects can be obtained.

(1) According to the first aspect of the present invention, a connection member having fire resistance is provided on the lower joints of the two panels to be connected, and the protrusion between the panels is provided on the upper joint. It is possible to fill the refractory seal material by supporting the backup material that is supported by being straddled over the panel, so that the joint members can make up the joints of the panel and the flame generated at the time of the fire wraps around the upper part. Can be prevented. In addition, the connecting member can have a function of a secondary gutter. Furthermore, since the fire-resistant seal material is filled between the two panels in support of the backup material laid across and supported between the ridges of both panels, it is possible to reliably fill the fire-resistant seal, Sealability can be improved.

(2) According to the second aspect of the present invention, similarly to the first aspect of the present invention, the joint portion of the panel can be covered with the connecting member, and the flame generated at the time of a fire is formed on the upper portion. It is possible to prevent sneaking around, and the connecting member can have a function of a secondary gutter.
In addition, the refractory seal material is filled between the two panels by supporting the backup material supported by the connecting member provided between the two panels, so that the refill of the refractory seal can be ensured. Can be improved.

(3) According to the third aspect of the present invention, the refractory sealing material is filled into the concave groove formed by the hanging piece formed on the connection side end face of the frame material and the backup material.
In addition to the above (1) and (2), the filling of the sealing material is further ensured, and the sealing performance can be further improved.

(4) According to the fourth aspect of the invention, since one side of the connecting member is fixed in the locking groove by the fixing member, the connecting member is further raised in addition to (1) and (2). And misalignment can be prevented.

(5) According to the fifth aspect of the invention, similarly to the first and second aspects of the invention, the joint portion of the panel can be covered with the connecting member, and the flame generated at the time of fire can be reduced. Can be prevented from going around the top,
Further, the connecting member can have a function of a secondary gutter. In addition, the upper holding member and the lower holding member are respectively engaged with the upper and lower surfaces of the ridges of both panels to be connected, and the upper holding member and the lower holding member are fastened by a fastening member, so that both panels are fastened. By sandwiching the ridges, even when the joints are slightly expanded during heating when exposed to high temperatures, the joints do not ignite, ignite, etc., and the connected state of the panel can be maintained. it can. Therefore, the fire resistance can be improved, and the thickness of the panel can be reduced to reduce the weight.

(6) According to the sixth aspect of the present invention, the connecting member is formed with a groove having an upper opening so as to form a gutter, so that rainwater or the like invades the joints of the panel. Even if it does, since it can be received by the concave streak of the connecting member, in addition to the above (1), (2), and (5), it is possible to further improve the raining.

(7) According to the seventh aspect of the present invention, the locking groove is formed in a narrow opening shape, and the connecting member is formed with the engaging piece capable of engaging with the narrow opening of the locking groove. In addition, positioning at the time of attaching the connecting member can be facilitated, and misalignment of the connecting member can be prevented.
