Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting device for surface structural members constituting the roof or outer wall of a building, and in particular to a connecting device for surface structural members that can cope with expansion and contraction of the surface structural members due to temperature changes between winter and summer. This paper proposes a connecting device for structural members.

The present applicant has already proposed a connecting device in which a scrap plate is placed on the lower surface of the surface structure members to be connected, which is provided with insertion grooves into which the ends of the surface structure members are respectively fitted, for example, in Japanese Utility Model Application Publication No. 54-152526. It is proposed in the official bulletin.

According to this connecting device, the surface structure materials can be connected by the simple operation of inserting the ends of the surface structure materials into the insertion grooves, but the surface structure materials expand and contract, especially elongate, due to temperature changes. It was then discovered that there was a risk of deformation because there was no place for it to escape. In other words, for example, if the surface structure material is inserted and connected until it touches the bottom wall of the insertion groove during construction in the winter, the surface structure material will thermally expand in the summer and exert strong pressure on the bottom wall of the insertion groove. At the same time, a large thermal stress is generated in the surface structure material itself, and an accident occurs in which it bends and floats up.

The present invention has been proposed in view of the above, and includes a surface structure member having an engaging portion bent outward at the rear edge and an engaging portion bent inward at the front edge, and a pair of left and right sections to be connected. A scrap board located on the lower surface of the connection part of the surface structure material and having an insertion edge on at least the front edge that is inserted into the locking part of the surface structure material, and a scrap board located between the side edges of the left and right surface structure materials and spaced apart. The present invention provides a connecting device for surface structure members, which has a position regulating tongue piece on the rear edge for holding the surface structure member, and includes a cover material that is attached to the surface of the side edges of the left and right surface structure members.

The present invention will be described below with reference to embodiments shown in the drawings.

Figure 1 shows the scrapboard 1 used to form the exterior wall of a building.
This shows an example of the arrangement of the surface structure members 2, in which the waste board 1 is located on the lower surface of the connecting portion of the surface structure members 2 that are adjacent to each other at the same height. In order to prevent rainwater from entering, the waste boards 1 are shifted in position between the vertically adjacent surface structure members 2, 2 as shown in the figure. 3 indicates the support material of the outer wall.

The surface structure material 2 is composed of a metal plate, and the second
As shown in the figure, it has an engaging portion 4 bent outward at its rear edge in the longitudinal direction, and a locking portion 5 bent inward at its front edge. Note that the reference numeral 2a in FIGS. 3 and 4 is an elastic sheet made of urethane foam or the like stuck to the back surface of the surface structure material 2.

On the other hand, the waste plate 1 is formed by extruding aluminum or the like, and has a groove-shaped edge 6 at its rear edge into which the engaging part 4 of the surface structure material 2 is fitted.
An insertion edge 7 is provided at the lower edge to be inserted into the locking portion 5 and brought into a fitted state. A pair of left and right insertion grooves 10 are formed in the center of the waste board 1 by a vertical wall 8 in the vertical direction and an upper wall 9 extending parallel to the waste board 1 on the vertical wall 8.
is formed. Reference numeral 11 denotes a vertically long protruding ridge formed on the waste board 1, and a plurality of ridges are provided in the longitudinal direction of the waste board 1. The protruding ridges 11 have the function of causing the rainwater to flow downward through the flat portions 12 between the ridges, even if rainwater should infiltrate from the joint portion of the surface structural member 2.

Further, if necessary, an insertion position regulating tongue piece 14 is provided projecting from the center of the engaging portion 4 of the waste plate 1. This insertion position regulating tongue piece 14 comes into contact with the side edge of the surface structure material 2 inserted into the insertion groove 10 of the waste board 1, and regulates the maximum insertion depth of the surface structure material 2 into the insertion groove 10. can do.

Further, the cover material 15 that covers the upper surface of the waste board 1 is made of, for example, a metal plate or a resin material.
The rear edge has a second edge 16 located within the engaging portion 4 of the surface structure material 2, and the front edge has a groove-shaped first edge into which the locking portion 5 of the surface structure material 2 is fitted. A portion 17 is formed. A position regulating tongue piece 18 is extended in the center of the second edge 16 to be inserted between the side edges of the left and right surface structural members 2, 2 whose maximum approach position is limited.

Therefore, the waste board 1 and the cover material 1 according to the above configuration
5 to connect the surface structure members 2, 2, the engaging portions 4 of the left and right surface structure members 2, 2 are fitted into the groove-shaped edges 6 of the scrap board 1, and the engagement portions of the surface structure members 2 are inserted. Stop part 5
The insertion edge part 7 is fitted into the inner part, the surface structure material 5 is slid onto the waste board 1, and the ends thereof are fitted into the insertion grooves 10, respectively.

Then, the cover material 15 is attached to the left and right surface structure members 2, 2.
, the first edge 17 is fitted to the outer surface of the locking part 5 to a certain extent, and the second edge 16 of the cover material 15 is positioned within the engagement part 4 to a certain extent, The left and right surface structure members 2, 2 are slid on the scrap board 1, and the side edges are fully fitted into the insertion grooves 10. Further, the cover material 15 is sufficiently moved upward to be fully fitted onto the outer surface of the locking portion 5 of the structure material 2 on each side of the first edge 17, and the second edge 16 is engaged. The position regulating tongue piece 18 is positioned within the portion 4 and between the side edges of the left and right surface structure members 5.

Then, since the side edges of the surface structure members 2, 2 are regulated by the position regulating tongues 18 of the cover material 15, the position of the cover material 15 itself is also regulated.

Therefore, the position regulating tongue piece 18 accurately regulates the position of the cover material 15 when constructing the roof or outer wall, and prevents the surface structural members 2, 2 from thermally expanding due to temperature differences due to seasonal changes after the roof construction is completed. Sometimes, even if the side edges of the surface structure members 2, 2 are extended, they will bite into the side edges of the position regulating tongue piece 18.

Although the present invention has been described above based on the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and can be implemented in any manner as long as the configuration described in the claims is not changed. can.

For example, in the construction method described above, most of the cover material is fitted onto the waste board in advance, the side edge of one side structural member is fitted with the waste board, and then the edge of the other side structural member is fitted into the waste board. Then, the cover material may be fully fitted onto the connecting portion of the surface structure material.

In summary, according to the present invention, there is provided a surface structure member having an engaging portion bent outward at the rear edge and a locking portion bent inward at the front edge, and a pair of left and right surface structure members to be connected. A scrap plate located on the lower surface of the connecting part and having an insertion edge on at least the front edge that is inserted into the locking part of the surface structure member, and a position that is located between the side edges of the left and right surface structure members to maintain the spacing. It has a regulating tongue on the trailing edge,
Since it is equipped with a cover material that is attached to the surface of the side edges of the left and right side structure members, the position of the cover material can be accurately regulated during roof construction, and the cover material will not tilt or connect the surface structure members. There is no possibility of rainwater coming off from the parts and disturbing the appearance, or rainwater entering the attic through the joints of the surface structural members. Even if the surface structure material expands due to temperature changes due to seasonal changes after the construction of the roof or exterior wall, only a small portion of the position regulating tongue or edge of the surface structure material will be bent or cut. Since no pressure is applied to almost the entire length of the edge of the surface structure material, the surface structure material will not bend and become wet with rainwater or be blown away by the wind.

In addition, the position regulating tongue piece can be integrally molded when forming the cover material, and the cover material can be widely used regardless of the structure of the surface structure material or the scrap board, making it highly practical. .
