Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a structure for attaching building boards to structural members.

<Prior Art> Fasteners, bolts, etc. are usually used to attach building boards between structural members. Nuts or bolts are fixed in advance to the building board, and the bolts or nuts are tightened to this via the fasteners attached to the structural member. The method of tightening is usually to place bolts and nuts in a direction substantially perpendicular to the building board.

<Problems to be solved by the invention> That is, a bolt or nut is fixed in advance to a building board, and a nut or bolt arranged approximately perpendicular to the building board is screwed into the bolt or nut. The above method works well if there is enough room in the structural members, but if there is not enough room to set and tighten the nuts and bolts, construction is extremely difficult. In particular, when installing multiple building boards flush, use the above nuts,
It is necessary to adjust the entrance and exit through bolts, or even use a special adjustment bolt. Moreover, building boards attached in this manner tend to loosen with respect to structural members over time.

As described above, in the conventional mounting structure, the mounting construction is complicated and the reliability of the mounting strength is often lacking.

<Means for solving the problems> This invention was devised in view of the above problems.
A reaction piece is formed on the fastener, a sliding washer having a pressing piece is attached to the reaction piece, and the reaction force generated when the bolt is tightened causes the sliding washer to slide and the bolt to be moved. The movement of this bolt draws the building board toward the fastener, that is, toward the structural member.

<Operation> If a bolt is inserted and tightened in the vertical direction, that is, in the in-plane direction of the building board, the reaction force from the reaction piece will cause the bolt itself to move to one side of the fastener. As a result, the building boards come close to the structural members. Moreover, since the sliding washer and the reaction piece repel each other and form a so-called spring washer mechanism, the bolt can be installed without loosening the clamping force.

<Example> The mounting structure of the building board of the present invention will be described in detail below based on the drawings.

Fig. 1 is a partially omitted perspective view showing the mounting structure of the present invention, Fig. 2 is a schematic longitudinal cross-sectional view of the same, Fig. 3 is a schematic plan view of the same, and Fig. 4 is a mounting structure seen from the structural member side. It is a figure showing a structure.

The building board 1 is made of an asbestos-cement board, a flexible board made of cement mixed with synthetic fibers, inorganic fibers, etc., or a composite board of these and other materials. Further, a frame material 11 is attached to the outer periphery or inner surface of the building board 1. As the frame material 11, for example, a square hollow steel pipe material or the like is used. A vibration-proof packing material P made of neoprene rubber or the like is interposed between the building board 1 and the frame material 11, and is riveted with blind rivets r.

On the other hand, as the structural member 2, a steel material having a substantially H-shaped cross section and consisting of flanges 21, 22 and a web 23 is used. This structural member 2 is erected according to the width interval of the building board material 1.

As means for attaching the building board 1 to the structural member 2, fasteners 3, sliding washers 4, and bolts 5 are used. The fastener 3 is the frame material 11
It consists of a fixing part 31 that is fixed to the frame member 11, and a fixing part 32 that clamps the flange 21 of the structural member 2 between the frame member 11 and the frame member 11. The fixing part 31 has a substantially inverted U-shape in side view by the side piece 31-1 and the upper and lower pieces 31-2, 31-3, and the frame member 11 is fitted between the upper and lower pieces. put in. Therefore, the upper and lower pieces 31-2,
31-3 each have a loose hole 3 that is long in the χ direction in the figure.
3 and 34 are drilled.

On the other hand, the fixing section 32 is connected to the side piece 31- of the fixing section 31.
1, the upper and lower pieces 31-2 and 31-3 are made of plate members extending in a crank shape in a direction substantially perpendicular to the upper and lower pieces 31-2 and 31-3.

A reaction force piece 31A is formed at the tip of the upper piece 31-2 by bending it outward from the upper piece 31-2, and a reaction force piece 31B is formed by bending the lower piece 31-3 outward in the same way.
is formed. Both reaction force pieces 31A, 31B have inclined surfaces 31a, 31b having predetermined inclinations, respectively.

On the other hand, the sliding washer 4 has a substantially inverted L-shape in side view with a supporting piece 41 and a pressing piece 42, and a loose hole 4 that is long in the χ direction in the figure is located approximately at the center of the pressing piece 42.
3 is drilled. Incidentally, bolt holes 11a and 11b having substantially the same diameter as the shaft portion 51 of the bolt 5 are bored in the upper and lower surfaces of the frame member 11.

Next, specific construction for attaching the building board 1 to the structural member 2 will be explained. In order to simplify the explanation, the upper part of the fastener 3, that is, the upper piece 31-2
Only the sliding washer 4 and the like attached thereto will be explained. As described above, the frame materials 11, 11, . . . are attached to the building board 1 in advance. The fixing part 31 of the fastener 3 is attached to this frame material 11.
At the same time, the flange 2 of the structural member 2
1 is inserted between the frame material 11 and the fixing section 32.

Next, with the tip 42a of the pressing piece 42 of the sliding washer 4 in contact with the inclined surface 31a of the reaction piece 31A, the bolt hole 11a, loose hole 33, and loose hole 43 are roughly adjusted, respectively. Then, the shaft portion 51 of the bolt 5 is passed through each of these holes. and bolt 5
Screw the nut N onto the threaded portion 52 and tighten. Through this construction, the bolts 5 are tightened in the Y direction in FIG. During the above tightening, the pressing piece 42 of the sliding washer 4 is also pushed down along its loose hole 43, and as a result, the pressing piece 42 exerts a reaction force on the bolt 5.
The tip 42a presses the reaction force piece 31A in the χ direction in the figure.

On the other hand, the fastener 3 does not move in the χ direction because its fixing portion 32 is in contact with the flange 21 of the structural member 2. Therefore, the sliding washer 4 itself receives the reaction force from the reaction force piece 31A and slides in the X direction in the figure.
Then, the bolt 5 is also drawn toward the illustrated side piece 31-3 of the fastener 3 within the loose hole 33. However, since the bolt 5 penetrates the bolt hole 11a of the frame material 11 in a substantially aligned state, the frame material 11 itself is moved in the X direction via the bolt 5.

When the bolts 5 are tightened in the Y direction as described above, the building board 1 to which the frame material 11 is attached will move in the direction perpendicular to its surface (x in the figure), the so-called entrance/exit adjustment direction. Moreover, the sliding washer 4 and the fixed part 31
The upper piece 31-2 and the reaction force piece 31A have a space O, and a pair of spring washer mechanisms are formed between the bolt head 53 of the bolt 5 and the nut N. Therefore, the fastener 3 and the frame member 11, which are pressed together by the bolt head 53 and the nut N, do not easily loosen from each other.

<Effects of the invention> As explained above, according to the mounting structure of the invention,
By tightening the bolts in the in-plane direction (vertical direction) of the building board, it is easy to make them flush. In other words, even if there is not enough room on the structural member side, it becomes easy to adjust the entrance and exit of building boards. Furthermore, installation and adjustment can be done with an extremely simple structure, without requiring a dedicated in/out adjustment mechanism. Furthermore, since the mounting structure itself forms a spring washer mechanism, the clamping force of the bolt is not reduced and the building board material is not rattled.
