Description

The present invention relates to the structure of a joint cover device for covering a joint portion provided on the roof of a building or the like.

Large buildings are built by dividing the structure into multiple skeletons with gaps between the skeletons in order to avoid the effects of changes in the temperature of the skeletons that make up the building and the load applied in the event of an earthquake. The walls, floors, and ceilings of the skeleton that sandwich the gap are integrally connected via expansion joints, and the openings of the skeleton facing the roof and roof of the building are covered with a joint cover device erected between the skeletons.

As a conventional joint cover device for a roof, for example, as shown in FIG. 18, a cover body 103 wider than the gap 100 is attached to the outer wall of one of the skeletons 101 facing each other across the gap 100, and the other skeleton 102 is attached. There is known a structure in which the draining member 104 provided on the parapet of No. 1 is brought into contact with the lower surface of the cover main body 103 to close the gap 100 (see, for example, Patent Document 1).

As shown in FIG. 19, the cover main body 103 is composed of a steel base material 103a and a stainless steel panel 103b, but instead of the cover main body 103, it is composed of a thin-walled holder and a panel. Also known are those composed of a composite honeycomb panel in which a core material cut out from a steel block and processed with a honeycomb is surrounded by a frame plate and a lid plate.

Japanese Unexamined Patent Publication No. 8-232351

In the conventional joint cover device, the cover body composed of a holder and a panel has an advantage of low manufacturing cost, but has low resistance to wind load. This configuration is not suitable for large joint covering devices that cover the skeleton gaps of large buildings.
On the other hand, the one in which the cover main body 103 is made up of the steel base 103a and the panel 103b shown above and the one made up of the composite honeycomb panel have high resistance to wind load, and the product width can be set wide. , These have the disadvantage that the number of processing steps is large and the manufacturing cost is high.

In addition, the latter two are made in one piece at the factory and brought to the construction site for assembly, but if the size of the cover body itself including the product width is large, the rooftop of the building In addition to making it difficult to transport to the construction site, there is a problem that the overall weight increases, which makes it inconvenient to handle and makes the workability poor.

Furthermore, in the latter two, in the construction site where the dimension in the length direction of the gap is large, multiple cover bodies are lined up along the gap and connected integrally, and the connection part is filled with a sealing material and connected. Although the waterproofness of the part is ensured, when the sealing material deteriorates over time, cracks, breaks, and peeling occur, and rainwater may infiltrate the inside of the joint cover device from such a part.

In view of such problems of the prior art, it is an object of the present invention to construct a joint cover device that is easy to transport, has high strength, and is excellent in workability.

In order to solve the above problems, the present invention relates to a joint covering device for covering a gap opening provided on a roof or a roof of a building.
A cover body that is attached to one of the skeletons facing each other with a gap in between and projects from the skeleton to the upper part of the other skeleton, and a cover body that is attached to the upper part of the other skeleton and is attached to the lower surface on the tip side of the cover body. Consists of abutting receivers
In the cover body, a plurality of cover materials made of aluminum profiles provided with connecting portions that can be connected to each other on both sides are arranged in parallel along the length direction or the width direction of the gap, and the covers are adjacent to each other. It is characterized by having a structure in which the side portions of the material are connected to each other and joined together.

According to this, the cover main body of the joint cover device is formed by integrally splicing a plurality of cover materials made of aluminum profiles. Since the cover material is molded from an extruded aluminum profile, it has high rigidity, and the cover body, which is composed of a plurality of spliced aluminum members, also has sufficiently high rigidity as a whole. Since the cover body has high strength and is strong against wind load even when mounted on the roof of a building, it will not be deformed or damaged even if it receives a large wind pressure, and it is possible to set a large product width. ..
The cover material made of aluminum profile is lightweight and easy to carry and handle. At the construction site, while arranging the cover materials along the length direction of the gap, the side parts of the adjacent cover materials are sequentially connected to each other. It is possible to form and attach the cover body by the simple work of joining. Since the cover can be installed on-site without having to manufacture the cover body in advance at the factory, the processing cost can be kept low, and the workability of the work in this kind of high-altitude construction site where safety must be taken into consideration. Can be improved.

In the joint cover device having the above configuration, the cover material constituting the cover main body has a mating portion on one side thereof and a mating portion on the other side. Each portion is provided and formed, and the cover materials can be joined to each other in a continuous manner by joining the combined portions of the other cover materials to the combined portions of the cover material.
The cover body is configured by joining the side portions of a plurality of cover materials together, and the surface of the cover body is a continuous cover surface. Therefore, the cover has a length corresponding to the length of the gap by adding the cover materials. The main body can be assembled and formed by a simple operation, there is no need to fill the connection part between the cover materials with a sealing material, and it is possible to ensure the waterproofness of the cover main body by joining the cover materials together. Is.
Further, the cover main body may be configured by arranging the cover materials along the width direction of the gap and connecting the side portions of the adjacent cover materials to each other and splicing them together.

A large wind pressure is applied to the joint cover device installed along the opening surface of the gap facing the rooftop when a typhoon occurs, and the shaking of the skeleton is transmitted and vibrates even when an earthquake occurs. When the product width and the wind load are large, the load applied to the connection portion with the frame of the cover body is also large, and the connection portion may be damaged depending on the magnitude of the external force received by the typhoon or the earthquake.
In order to prevent such a situation from occurring, the joint cover device having the above configuration may be reinforced by connecting the skeleton and the upper surface portion or the lower surface portion of the cover body attached to the skeleton with a support arm. can.

When the support arm is connected to the cover body to support it, the stress acting on the cover body when the external force is applied is not unevenly distributed, so that the position is closer to the tip side than the center in the width direction of the cover body. It is preferable that the ends of the support arm are connected, but the connection position of the support arm to the cover body is restricted in order to secure the movable amount of the skeleton depending on the connection between the skeletons facing each other with a gap in between. There is.
For example, in a mode in which the cover body is bridged over the parapets facing each other with a gap between them and the joint cover device is attached, the connection position of the support arm is closer to the base of the lower surface of the cover body in order to secure the movable amount of the parapet. In such a case, the strength is reduced at the tip of the cover body, the protruding corners, etc., which is far from the connection position of the support arm, and the material bends or connects to the skeleton due to the stress acting when the external force is applied. The part may be damaged.
Therefore, in order to increase the strength of the tip end side of the cover body, an edge reinforcing body extending along the longitudinal direction of the cover body can be attached to at least the tip end side of the lower surface of the cover body. In order to increase the strength of the entire cover body, edge reinforcements may be attached in one or a plurality of rows on the original end side of the cover body with respect to the tip end.

In the joint cover device having the above configuration, the cover body is attached with a downwardly inclined slope from the root side to the tip side so that rainwater runs down the upper surface of the cover body. If it is installed at the joint portion of the joint device for the outer wall, when both devices move due to the occurrence of an earthquake, there is a risk of interfering with the joint device for the outer wall and causing a problem.
In addition, when the cushioning material is provided on the lower surface of the roof side end or the upper part of the joint device for the outer wall, the height changes greatly between the tip side and the root side, and when it moves, the load on the cushioning material is large and it is damaged. May occur.
Therefore, in order to avoid interference at the joint portion with the joint device for the outer wall, it is preferable to integrally provide a frame body having a flat lower surface at the lower portion of the end portion in the length direction of the cover body.

The joint cover device having the above configuration can be applied not only to the aspect of closing the opening of the gap provided on the roof or the roof of the building, but also to the aspect of closing the opening of the gap facing the eaves of the building.
As an aspect of the joint cover device that covers the opening of the gap facing the eaves of the building, a cover body that is attached to one of the skeletons facing each other across the gap and projects from the skeleton to the lower part of the other skeleton is used. A plurality of cover materials made of aluminum profiles provided with connection portions that can be connected to each other on both sides of the cover main body are arranged in parallel and adjacent to each other along the length direction or the width direction of the gap. The side portions of the cover material can be connected to each other and joined together. In the joint cover device installed in the gap facing the eaves, the gap is closed by the cover body to form the eaves ceiling.
Further, in the joint cover device for closing the opening of the gap facing the eaves, in the form in which the cover material is formed in parallel along the length direction of the gap, the cover body is arranged at the end of the cover body. The cover body is cut along the length direction thereof, the outer surface of the cover material including the cut portion is covered with the side frame material, and the side end portion of the cover body is accommodated to accommodate the cover body. It can be adjusted to an appropriate length.
