Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a connecting device for horizontal roofing surface structural members constituting the roof or outer wall of a building.

<Prior Art> The present applicant has already developed a connection device for surface structure members in which a scrap plate is placed on the lower surface of the surface structure members to be connected, each having an insertion groove into which the end portions of the surface structure members are inserted. , for example, Utsukai 54-
This is proposed in Publication No. 152526.

(Problems to be Solved by the Invention) According to this connecting device, the surface structure members can be connected by a simple operation of inserting them into the insertion grooves at the ends of the surface structure materials. It has been found that when it expands and contracts, especially when it expands, due to temperature changes, there is a risk of deformation because there is no escape area.For example, during construction in winter, the surface structure material may be inserted and connected until it touches the bottom wall of the insertion groove. If so, in the summer, the surface structure material thermally expands, exerting strong pressure on the bottom wall of the insertion groove, and large thermal stress is also generated on the surface structure material itself, causing an accident in which it eventually bends and floats up. do.

Means for Solving the Problems The present invention has been proposed in view of the above, and provides a surface structure having an engaging portion bent outward at the upper edge and a locking portion bent inward at the lower edge. a scrap plate located on the lower surface of the connecting portion of the pair of left and right surface structure members to be connected and having an insertion edge on at least the lower edge that is inserted into the locking portion of the surface structure members; and the left and right surface structure members. A connection device for surface structure members, comprising a position regulating tongue piece located on the upper edge to maintain a distance between the side edges of the surface structure members, and a cover material applied to the surface of the side edges of the left and right surface structure members. It provides:

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

Figure 1 shows an example of the arrangement of the scrap board 1 and the surface structure material 2 when composing the outer wall of a building. It is something to be positioned. 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 for the outer wall.

The surface structure member 2 is composed of a metal plate, and as shown in FIG. 2, an engaging portion 4 bent outward is provided at the upper edge in the longitudinal direction.
It has a locking part 5 bent inward at the lower 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 l is formed by extruding aluminum or the like, and has a grooved edge 6 on its upper edge into which the engaging part 4 of the surface structure material 2 fits inside, and a lower edge. is provided with an insertion edge 7 which is inserted into the locking portion 5 to form a base. 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 l 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 IO of the waste plate 1, and can regulate the maximum insertion depth of the surface structure material 2 into the insertion groove IO.

Further, the cover material 15 that covers the upper surface of the waste board 1 is formed from, for example, a metal plate or a resin material, and the upper edge thereof has a second edge 16 located within the engaging portion 4 of the surface structure material 2. A groove-shaped first edge 17 into which the locking portion 5 of the surface structure member 2 is fitted is formed at the lower edge. 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 planar structures 2.2 whose maximum approach position is limited.

Therefore, in order to connect the surface structure members 2, 2 using the waste board 11 cover material 15 according to the above configuration, the left and right surface structure members 2,
2 is fitted into the groove-like edge 6 of the waste board 1, and the insertion edge 7 is fitted into the locking part 5 of the surface structure material 2.
The surface structure material 5 is slid onto the waste board 1, and its ends are fitted into the insertion grooves 10, respectively.

Then, the cover material 15 is applied to the surface of the connecting portion of the left and right surface structure members 2.2, and the first edge '17 is fitted to the outer surface of the locking part 5 to some extent, and the second
The edges 16 of are positioned within the engaging portion 4 to some extent, and the left and right surface structural members 2.2 are slid on the scrap board 1 to fully fit the side edges into the insertion grooves 10. In addition, the cover material 15 is sufficiently moved upward to fully fit the first edge portion 17 to the outer surface of the locking portion 5 of each of the left and right surface structural members 2, and
The second edge portion 16 is positioned within the engaging portion 4, and the position regulating tongue piece 18 is positioned between the side edges of the left and right surface structure members 5.

Then, the side edges of the surface structure member 2.2 are regulated by the position regulating tongues 18 of the cover material 15, so that 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 during construction of the roof or outer wall, and prevents the surface structure material 2.2 from thermally expanding due to temperature differences due to seasonal changes after the construction of the roof is completed. In some cases, even if the side edges of the surface structure member 2.2 are extended, they will bite into the side edges of the position regulating tongues 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.

<Effects of the Invention> In summary, according to the present invention, a surface structure member having an engaging portion bent outward at the upper edge and a locking portion bent inward at the lower edge, and a pair of left and right to be connected. A scrap plate located on the lower surface of the connection part of the surface structure material and having an insertion edge on at least the lower edge to be inserted into the engaging part of the surface structure material, and located between the side edges of the left and right surface structure materials. It has a position regulating tongue piece on the upper edge that maintains the distance, and a cover material that is attached to the surface of the side edges of the left and right side structural members, so the position of the cover material is accurately regulated during roof construction. This prevents the cover material from tilting or coming off from the connection part of the surface structure material, which will disturb the appearance, and prevent rainwater from entering the attic from the connection part of the surface structure material. 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 part of the position regulating tongue or the edge of the surface structure material will be bent or cut. Since no pressure is applied to 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. .
