Description

[Detailed description of the invention] (Industrial application field) This invention relates to an expansion joint that covers the gap between the frames of a building.

(Prior Art) Conventionally, the cover member of this type of expansion joint is required to have corrosion resistance and wear resistance, so it is formed by bending and forming a stainless steel plate, etc. A spring member for elastically fastening to a pair of fixing members arranged on an adjacent frame was fixed to approximately the center of the web using screws, etc.; However, there were problems in that the surface side of the cover member was exposed, spoiling its appearance, and rainwater etc. entered through the mounting part, deteriorating the watertightness.

(Problems to be Solved) The present invention has been made to solve the above-mentioned conventional problems, and its purpose is to provide an expansion joint that has a good appearance and excellent watertightness.

(Means for Solving the Problems) In order to solve the above-mentioned technical problems, the present invention includes a pair of fixing members disposed opposite to each other on the frame of an adjacent building, and a spring straddled between the two fixing members. The expansion joint is comprised of a cover member that is attached to both of the fixing members via a member to cover a gap between the skeletons, and the cover member has the spring member on the back side of the cover body. A long or short substrate member to which the top portion is fixed is provided, and the substrate member and the cover member are integrally fixed to the sealing member at the visible and hidden end sides thereof by fastening means, and the fastening means is the sealing member. The expansion joint is constructed to be hidden by.

(Function) With the above configuration, a sealing function is achieved to the gap side from wind and rain.

(Embodiment) Next, the first embodiment of the present invention will be explained with reference to FIG.
1' is an expansion joint (hereinafter simply referred to as a joint) that is attached to wall-to-wall to cover the gap T1, and this joint 1 has a pair of long fixed members 2 and 3 and a spring member 4 and a cover member 5.

Both fixing members 2 and 3 forming this pair are made of a molded material extruded from a light alloy material such as aluminum, and are installed oppositely along the gap T1 side of the wall surface Wa of the building blocks W1 and W1'. Since the members 2 and 3 are formed in a symmetrical shape, the fixing member 2 on the left side of the figure will be explained. In its cross section, 2a is a mounting edge, and one end thereof has a fitting portion 2b into which the water stop plate 12 is fitted. The fitting portion 2b is formed with a locking edge 2c having a substantially sawtooth-shaped locking surface 2d on at least one surface facing outward.
The fixing members 2 and 3 formed in this way are attached to both the body parts W.
1, W1' is fixed to the wall surface Wa with mounting bolts 13.

The spring member 4 is made of an elastic member, such as a stainless steel spring plate, and is formed into a short length.
1. The cover member 5 is formed to have a substantially W-shaped cross section that can be elastically deformed in response to vertical, horizontal, front-back, etc. fluctuations of W1', and is arranged at predetermined intervals on the back side of the cover member 5. 5 is attached to the fixing members 2 and 3 in an attractive manner, and this spring member 4 has, for example, two approximately V-shaped spring portions 4a and 4b, and an upright connecting piece 4c thereof is in contact with the spring member 4. and is fixed with rivets, screws, welding means, etc. to form a substantially W-shaped cross section, and has an opening in the center, that is, the upper part (also referred to as the top) of the fixed part 4d, and corresponds to the opening. A substantially circular base locking portion 4e having a locking claw 4f cut and raised is formed. Furthermore, curved locking portions 4g that open downward are formed at both ends of the substantially W-shape, and locking claws 4h formed by cutting and raising are formed on the opening sides thereof.

The cover member 5 is composed of a cover main body 6 and a substrate member 7, and the cover main body 6 is formed by bending a stainless steel plate or the like, and has a substantially Z-shaped cross section on both sides of a horizontal web 6a. An edge 6b is formed, and a lower edge 6c of this side edge 6b serves as an attachment edge to the substrate member 7. Further, the substrate member 7 is formed into a substantially rib-like shape by a long connecting member 8 and a plurality of short substrates 9, and this connecting member 8 is mainly composed of a base frame 8a having a substantially U-shaped cross section. A base locking portion 4 of the spring member 4 is located approximately at the center of the upper edge 8b of the base frame 8a.
A locking edge 8c having an arrowhead-shaped locking portion 8d at the tip for locking e is formed along the longitudinal direction of the locking edge 8c. Further, the substrate 9 is formed in a short length, and side pieces 9b are formed at both ends of the horizontal web 9a along the back surface of the web 6a of the cover body 6 to contact the lower edge 6c of the cover body 6 in an overlapping manner. Further, two leg pieces 9c are provided approximately at the center of the web 9a, and a groove 9d into which the connecting member 8 is fitted is formed. The substrate 9 formed in this manner is fitted into the connecting member 8 through the grooves 9d at predetermined intervals, and the base frame 8a and the leg pieces 9c are fixed by screws, rivets, or welding means to form a substantially rib cage. A shaped substrate member 7 is formed.

Now, since the first embodiment is constructed as described above, even if the main bodies W1 and W1' change, the cover member 5 is elastically engaged with the fixed members 2 and 3 via the spring member 4. At the same time, the elastic deformation of the spring member 4 itself can absorb the relative fluctuations of the skeletons W1, W1', and the cover member 5 can be held in a stable state. The cover member 5 also includes a cover body 6 and a substantially rib-shaped substrate member 7.
The screws and rivets 11 are connected to the visible and hidden part where the lower edge 6c of the side edge 6b and the side piece 9b are overlapped.
Since the cover member 7 is integrally fastened together with the airtight member 10 to form a composite body, and the screws and rivets 11 are hidden by the airtight member 10, the rigidity of the cover member 7 can be increased and bending and Twisting can be prevented, and in particular, since the visible and hidden side, which is the essential airtight part, is integrally fastened with the airtight member 10 and hidden by the same airtight member 10, the installation state of the airtight member 10 is stable and the seal is secured. The service can be performed satisfactorily, the screws and rivets 11 can be protected from rust, etc., their fastening function can be ensured, their durability can be improved, and since they are not exposed, the overall appearance of the joint 1 can be improved. can do.
