Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a dry construction structure for constructing a wall using wall construction boards such as tiles, stone slabs, ceramic boards, concrete panels, etc. Suitable for construction when using
This aims to improve the impact resistance of the constructed wall surface, as well as to simplify and shorten the construction work.

2. Description of the Related Art A widely used construction structure for constructing a wall using large-sized wall construction plates will be described with reference to drawings. As shown in FIGS. 12 to 14, the construction procedure is to fix the vertical portion 4a of the L-shaped fixing member 4 with a nut 5 to the anchor bolt 3 driven into the mounting surface 2 of the frame 1 or the like. Next, a horizontal support member 7 is attached to the horizontal portion 4b of the fixing member 4 using bolts and nuts 6. The support member 7 has an insertion hole 7a formed on the front side thereof. Subsequently, the wall structure plate 8 is placed below the support member 7, and the support pin 9 is inserted into the insertion hole 7a and inserted into the insertion hole 8c provided in the upper end surface 8a of the wall structure plate 8. . Further, after placing the upper wall component plate 8 on the upper surface of the support member 7 and inserting the support pin 9 into the insertion hole 8c provided in the lower end surface 8b of the wall component plate 8, the wall component plate 8 is placed. The support pin 9 is inserted into the insertion hole 8c of the upper end surface 8a of the wall structure plate 8 to attach it. In this way, the wall surface forming plates 8 are sequentially attached from the bottom to the top.

[0003] Each wall surface forming plate 8 constructs a wall surface by supporting at least two places on each of the upper end surface 8a and the lower end surface 8b with support pins 9. A joint material 10 is filled between the wall surface constituent plates 8, 8 as required. Note that the bolt insertion holes 4c, 4d, and 7c formed in the L-shaped fixing member 4 and the support member 7 are all formed into elongated holes so as to be adjustable.

0004

[Problems to be Solved by the Invention] However, the conventional construction structure has the following drawbacks. (a) Impact force, such as wind pressure, applied to the surface of the wall structure plate 8 is transmitted to the support pin 9 through the insertion hole 8c of the wall structure plate 8. Therefore, in order to improve the impact resistance of the construction wall surface, it is necessary to make the support pin 9 thicker and to make the insertion hole 8 with a larger diameter.
It is necessary to make the wall surface forming plate 8 thick so that the wall thickness near c does not become thin. In this case, an increase in the weight of the wall structure plate 8 is unavoidable, and it is necessary to increase the size of the support member 7 and the fixing member 4, which leads to a decrease in work efficiency during construction and an increase in cost.

(b) The insertion hole 8c of the wall structure plate 8 is
The diameter is larger than that of the support pin 9 in order to absorb errors in the drilling position. Therefore, the gap between the insertion hole and the support pin 9 is filled with a filler. However, before the filler hardens, the wall surface forming plate 8 will fall down and tilt in either direction, so it is necessary to prevent this from happening. Therefore, the upper part of the wall structure plate 8 is temporarily fixed by another means. However, this temporary fixing increases the number of man-hours, leading to a decrease in work efficiency during construction and an increase in costs.

(c) If the finish of the mounting surface 2 is very poor and there are irregularities, after adjusting the movement of the support member 7 in and out of the fixing member 4 fixed to the mounting surface 2 using bolts and nuts 6. It is necessary to support the wall structure plate 8 with support pins 9 that are adjusted in and out, and to construct a wall surface without unevenness. However, if the adjustment of the support member 7 into and out of the fixing member 4 is not perfect, readjustment is required. However, after supporting the wall structure plate 8 at four locations with the support pins 9,
It cannot be readjusted unless the wall component plate 8 is removed. In this case, removing and readjusting the wall surface component plate 8 requires a great deal of effort and lengthens the construction period.

[0007] In order to solve the above problems, the present invention has the following features:
The purpose of the present invention is to provide a construction structure for a wall component plate that can easily and quickly construct a wall structure that simulates impact resistance.

[0008]

[Means for Solving the Problems] The means adopted by the present invention is that in a structure in which a wall component plate is attached to a mounting surface, a backing tool that comes into contact with the back surface of the wall component plate is provided between the mounting surface and the wall component plate. A hook equipped with an elastic member that generates an elastic force toward the mounting surface is fixed to the mounting surface, and a hook provided at the tip of the elastic member is inserted into a recess drilled in the side surface of the wall component plate. This is a construction structure of a wall structure plate, characterized in that the wall structure plates are engaged with each other, and the wall structure plate is attracted to the mounting surface side by the elastic force of the elastic member.

The backing tool includes a fixing member fixed to the mounting surface, a support member that is connected to the horizontal portion of the fixing member so as to be adjustable in and out, and comes into contact with the lower end surface of the wall component plate.
It may also include an upright member that stands up from the support member and comes into contact with the back surface of the wall structure plate, so that the wall structure plate can be adjusted in and out.

[0010] The backing tool also includes a fixing member fixed to the mounting surface, and a support bolt that is threaded into a vertical portion of the fixing member toward the mounting surface and comes into contact with the lower end surface of the wall component plate. , and a nut that is threaded onto the support bolt and comes into contact with the back surface of the wall component plate, so that the wall component plate can be adjusted in and out.

Furthermore, the backing tool includes a fixing member fixed to the mounting surface, and a support bolt screwed into a vertical portion of the fixing member toward the mounting surface, and the support bolt is attached to the wall component plate. At the same time, a joint part is formed at the tip of the bolt to which a rotating tool is connected, so that the wall component plate can be adjusted in and out from the front side of the wall component plate.

The attachment device includes a fixing member fixed to the mounting surface, and the elastic member joined to the protruding portion of the fixing member so that it can be moved in and out, and is adapted to accommodate unevenness of the mounting surface. Sometimes I do.

[0013] The mounting surface may be the surface of a substrate attached to the building's roof, and may have few irregularities. The backing tool includes a long fixed piece fixed to the mounting surface, an upright piece that is joined to the fixed piece and comes into contact with the back surface of the wall structure plate, and a standing piece that projects from the upright piece and that is connected to the wall structure. It may be provided with a support piece that comes into contact with the lower end surface of the plate, and supports a plurality of wall surface constituent plates at the same time.

[0014]

[Operation] The pressing force applied to the surface of the wall component plate is transmitted to the mounting surface via the back surface of the wall component plate and the backing tool. At this time, the back surface of the wall component plate is in contact with the backing tool in a planar or linear manner, so compared to the conventional support structure in which a support pin is inserted into the insertion hole where stress concentration occurs, the wall component plate The stress generated is dramatically reduced. Therefore, the impact resistance of the constructed wall surface can be dramatically improved, and the wall structure plates can be made thinner than before.

[0015] The wall component plate is not easily moved because it is attracted to the mounting surface side by the elastic force of the hook and is crimped to the backing tool. Therefore, even when the wall component plate is more firmly bonded to the backing tool or the hooking tool with an adhesive, there is no need to temporarily fix the wall component board.

When the wall component plate is pulled toward the front away from the mounting surface, the elastic member of the hook is elastically deformed, and the hook is pulled out toward the front while maintaining engagement with the hook portion of the hook. When a wall component board is pulled out, when creating a working gap between an adjacent wall component board and the backing tool can be adjusted in and out, it is possible to level the surface of the constructed wall without removing the wall component board. can.

[0017] When the support bolt of the backing tool has a flange that contacts the back surface of the wall component plate and a joint portion that connects the rotating tool, the support bolt can be inserted and removed from the front side of the wall component plate. Since it is adjustable, it is possible to level the surface of the constructed wall without removing the wall component plates.

[0018]
