[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fireproof expansion joint device for closing a space between building structures.

[0002]

[Prior Art]

 Conventionally, in order to cope with the deformation and distortion of buildings due to the occurrence of earthquakes and ground changes, the inner and outer walls, ceilings, or floors are cut at appropriate edges with joints to absorb the deformations and distortions. The use of joint members to prevent damage to buildings is a very important matter to consider in building design, especially in countries such as Japan where there are many earthquakes and subsidences. Expansion joint equipment is used.

[0003]

[Problems to be solved by the device]

 However, in such a conventional expansion joint device, the fire resistance was insufficient, or in order to provide the fire resistance, a separate fire resistant material was provided inside the joint member, so the structure was Since it is complicated and there are many built-in members, it is difficult to construct and it is easy to make a mistake, and it is troublesome and troublesome. In particular, it is difficult to install expansion joint devices between buildings in buildings that use glass sheets on the wall, which has been increasing in recent years, and it is difficult to install appropriate columns on the glass sheets in the corners. The expansion joint device must be installed as a mounting member, which is not desirable for the aesthetic appearance of the building, and there are problems that the glass plate is easily damaged because the columns are fixed to the glass plate. Be done.

Therefore, the object of the present invention is to solve the above problems in the prior art by using a metal water stop plate and an H-shaped edge member attached to the end of the glass plate of the building structure. (EN) An expansion joint device for a building skeleton having a simple structure in which a central cover and a central cover are attached and which is extremely easy to install and install on site.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, according to the present invention, an expansion joint device for a building structure is provided with a pair of glass plates forming the wall surface of each adjacent building. H-shaped edge material, metal water stop plate with one end attached to the web portion of one edge material and the other end fitted and locked to the other edge material, groove type attached to the web portion of the edge material It is characterized in that it is composed of a metal central cover held between the flange portion and a member.

[0006]

[Action]

 In the expansion joint device of the building structure of the present invention thus constructed, the edge member having the H-shaped cross section, the water blocking plate, the groove member and the central cover have been assembled in advance in the factory, and this pre-assembled It is only necessary to install the expansion joint device at the end of the glass plate of the building structure according to the gap between the adjacent building structures at the site, and it can be installed easily and in a short time, and it can be displaced due to an earthquake or ground change. Even if the water stop plate and the central cover are appropriately displaced, it is possible to respond appropriately, and the glass plate is not damaged in any way, can be easily configured with a small number of parts, and can be installed securely and quickly. Can do

Other objects, features and advantages of the present invention will be apparent from the detailed description given below with reference to the accompanying drawings.

【Example】

 An embodiment of an expansion joint device for a building frame of the present invention is shown in the drawing. As shown in FIG. 1, the expansion joint device 10 for a building frame of the present invention is a wall surface of each adjacent building frame. A pair of edge members 11 and 12 each having a substantially H-shaped cross-section, which are attached to the end portions of the glass plate 2 that forms the edge of the glass plate 2. A water stop plate 13 made of metal, which is fitted and locked to 12, a groove-shaped member 14 attached to the web portion 16 of each of the edge members 11, 12, and one flange of each of the edge members 11, 12 by these groove-shaped members 14. It is mainly composed of a central cover 15 made of metal which is held between the central cover 15 and the portion 17.

As shown in the drawing, the edge members 11 and 12 each having a substantially H-shaped cross section are made by welding, forging, extruding or the like from an appropriate metal material such as stainless steel, iron, and aluminum, and each adjacent building frame. The end portion of the glass plate 2 constituting the wall surface is fitted between the flange portions 17, 17 of the edge members 11, 12 having an H-shaped cross section and watertightly sealed by the backer 3 and the caulking material 4. A water stop plate made of metal, for example, stainless steel, iron, aluminum alloy or the like, via a butyl tape 19 on the web portion 16 of one of the edge members 11 and 12, for example, the left side in the drawing, of the edge member 11. Thirteen folded ends are attached. The water stop plate 13 made of metal is provided with two substantially triangular protrusions 22 and 23. When the protrusions 22 and 23 are attached to the edge member 11, the protrusions 22 and 23 are respectively attached to the edge members 11 and 12. It is adapted to be engaged with the inner surface of the flange portion 17. Further, the bent end of the water blocking plate 13 is attached to the web portion 16 of the one edge member 11 together with the groove member 14 by the bolt 21, and the other end is attached to the edge member 12 as shown in the figure. It is fitted between one of the flange portions 17 and the groove member 14 so that it can be appropriately slid and displaced in the event of an earthquake or ground change.

Ordinary channel steel or aluminum alloy mold material can be used for the pair of channel members 14, and a butyl tape is applied to the web portion 16 of each edge member 11 and 12 by a bolt 21 in one of the flange portions. It is attached with 19 and 20 in between. When mounting these groove-shaped members 14, a metal central cover 15 made of stainless steel, iron, aluminum alloy or the like is provided between the other flange portion of the groove-shaped member 14 and the flange portion 17 of the edge member 11. It is sandwiched and attached, and like the water stop plate 13, it can be displaced in response to earthquakes and ground changes. The metal central cover 15 can be curved as shown, bent into a polygonal shape or the like, or bent.

The expansion joint device 10 of the building structure of the present invention having the above-described structure can be assembled in advance in the factory with the edge members 11, 12, the water stop plate 13, the groove member 14, and the central cover 15 in advance. The expansion joint device 10 need only be attached to the end of the glass plate 2 of the building frame according to the space between the adjacent building frames at the site, and can be easily and quickly installed.

[Effect of the device]

 According to the expansion joint device for a building skeleton of the present invention constructed as described above, it comprises a pair of edge members having an H-shaped cross section, a water stop plate made of a thin metal plate, a central cover, and a groove member. By simply inserting the end of the glass plate that forms the wall of the building frame between the flanges of the H-shaped edge material and filling the gap between the backer and caulking material, you can easily and securely install the structure. The water stop plate can be elastically displaced even when it is displaced due to an earthquake or ground change, and the center cover can be appropriately displaced to respond appropriately, and the glass plate is not damaged at all and is a small number of parts. It is possible to obtain an expansion joint device that can be easily assembled in a few steps and can be securely and quickly mounted.
