Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a large exosphere that absorbs the expansion and contraction of a large folded building board with a long span due to temperature changes using a movable receiving metal fitting that swings appropriately, and that has a simple structure.

BACKGROUND ART Conventionally, large construction boards (with a height of about 50 m or more) with long spans (about 10 to about 50 m in length) and continuous chevrons have been produced in factories.

This is transported to the site and lifted one by one onto the structure there using a large crane, etc., and is placed in parallel between the opposing structural members such as the top of the structure. A large exosphere such as a roof or wall is being constructed. Due to the long span of these large construction boards, they undergo thermal expansion and contraction due to temperature changes in the summer and winter, resulting in particularly large expansion and contraction. If this is not taken into account, thermal stress will occur within the large building board, causing serious problems such as causing the board rattling phenomenon, deforming the large building board, or damaging its attachment members. Defects occur. For this purpose, one end of the span is fixed or supported by a pin, and the other end is supported by rollers. This roller-supported type has the disadvantage that its structure is more complicated and expensive than a fixed type. Therefore, in the present invention, structural members are provided facing each other at a certain interval, a chevron-shaped fixed bracket is fixed on one of the structural members, and a trapezoidal chevron-shaped movable metal fitting is fixed on the other structural member. The upper ends of both inclined parts are pivotally attached to both lower ends of the part, and the lower ends of both inclined parts are fixed to the mounting parts of movable brackets which are pivoted to the respective inclined sides of both mounting parts. One longitudinal end of the large folded construction board is fixed to the fixed bracket, and the other end is fixed to the movable part of the movable bracket, or the other end is fixed to the movable part of the movable bracket. By attaching it with bolts and nuts via a compression coil spring that springs downward, even if the large folded construction board expands and contracts due to temperature changes, this expansion and contraction is absorbed by the movable bracket, and the large This invention solves the above-mentioned drawbacks by preventing thermal distortion and plate rattling phenomena in folded construction boards, and having a simple mounting structure, easy construction, and low cost.

Its structure will be explained with reference to the drawings.

Reference numeral 1 denotes structural members such as beams, which are provided in at least a pair substantially parallel to each other on the top or side of the structure.

It is approximately equivalent to this strong compression coil spring 18. It is a two-way bulging strip, and is formed in a bulge so as to be continuous in the longitudinal direction on the bottom part 8 of the large-sized folded construction board 7.

Reference numeral 21 denotes bulging portions, which are formed on the slope portion 9 of the large folded construction board 7 at appropriate intervals in the longitudinal direction.

Next, the effects will be explained.

First, in the invention stated in the first claim,
Structural members 1 and 1 are provided in a structure facing each other, a chevron-shaped fixed bracket 2 is fixed onto one of the structural members 1, and a trapezoidal chevron-shaped movable part 4 is fixed onto the other structural member 1. The upper ends of both inclined parts 5, 5 are pivotally connected to both lower ends, and both inclined parts 5, 5 are
The lower end of the movable bracket 3 is fixed to the oblique side of each of the two mounting parts 6, 6, and one longitudinal end of the metal large folding plate building board 7 is attached to the fixed receiver. By fixing it to the metal fitting 2 and fixing the pond end side to the movable part 4 of the movable receiving fitting 3, the large-scale folded metal construction board 7 with a large span is formed.
However, even if the movable part 4 of the movable bracket 3 expands and contracts due to thermal expansion or contraction in response to temperature changes in the outside air in summer and winter, the movable part 4 of the movable bracket 3 will not cause the swinging of the oblique parts 5 (see Fig. 5). ), it can move in the same direction as the longitudinal direction of the large folded construction board 7 to absorb its expansion and contraction.

Further, the movable part 4 is fixed to the lower surface of the large folding construction board 7) and moves in parallel. That is, the movable part 4 is
The movable part 4 does not have an inclined shape because the oblique part 5 is interposed between the mounting part 6 and the upper part at two places. It is possible to completely eliminate the possibility of damaging or partially damaging the block construction board 7. Furthermore, when this large-sized folded construction board 7 expands and contracts, the oblique part of the movable bracket 3 swings a little, and the movable part 4 lowers a little. Since it is a plate, the height of the movable receiving metal fitting 3 is high, and even when it expands and contracts, the height that the movable part 4 lowers is extremely small. Therefore, almost no force acts to compress the large folded construction board 7, and the large enclosure can be installed in an extremely orderly manner without causing any distortion or deformation to the large folded construction board 7. . Furthermore, the movable bracket 3, which is the gist of the present invention, is divided into upper and lower parts and pivotally connected to each other, and its structure is extremely simple and can be manufactured at low cost. Similar to 2, it can be done simply and quickly, and the construction method is much better than the conventional roller type, and the construction cost can be significantly reduced. By using such a large-sized envelope, irregular thermal stress and thermal distortion are not generated within the large-sized folded construction board 7, and the plate rattling phenomenon can be prevented. In addition, in the invention described in the second claim, the other end side of the metal large-sized folding plate construction board 7 is connected to the movable part 4 of the movable receiving bracket 3 with a bolt 16.
, and screw the nut 17 onto the lower end of this bolt 16.
A compression coil spring 1 is inserted between the movable part 4 and the nut 17.
8, as the amount of expansion and contraction of the large folded construction board 7 increases, the swing angle of the oblique part 5 of the movable bracket 3 also increases, and the height at which the movable part 4 descends also increases. The force acting on the movable portion 4 resists the elastic force of the compression coil spring 18, causing the movable portion 4 to descend significantly.

Even if the movable part 4 descends in this way, the large folded construction board 7
The height of the height can be kept as is. That is, it is possible to cope with an increasing amount of expansion and contraction without applying strong compressive force to the large folded construction board 7. Therefore, the span of the large folded construction board 7 is
Even if the size is extremely large and the amount of expansion and contraction is large, the amount of expansion and contraction can be absorbed and installation work can be carried out in an orderly manner without giving undue distortion to the large folded building board 7. Further, in the present invention, the strength of the compression coil spring 18 can be adjusted as appropriate by the way the nut 17 is attached.
It is possible to adjust the strength to the best value by adjusting the plate thickness, height, width, section modulus, etc., increase the adhesion force, and prevent distortion etc. from occurring in the large folded construction board 7. Moreover, the present invention naturally exhibits the effects of the invention described in the first claim. In addition, in the invention described in the second claim, the top part 10 of the large-sized folded construction board 7 and the movable bracket 3
When an auxiliary compression coil spring 19 is interposed between the bolt 16 axis and the top surface of Even when the top 10 is pressed by the 16 bolts, the top 10 is supported by the elastic force of the auxiliary compression coil spring 19, so that the top 10 is not deformed in any way.
