[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an instrument for stretching a horizontal net for curing at a construction site.

[0002]

2. Description of the Related Art At a construction site, a horizontal net for curing is installed to close a gap between a wall surface of a building and an external scaffold. Conventionally, this horizontal net is connected to a wall (scaffold). It is stretched by binding to the building frame. Since this horizontal net obstructs the finishing blacking work, the groundwork repairing work, etc., in these works, the corresponding parts on the wall side are untied and removed.

[0003]

[Problem to be solved by the invention] When the unity of the horizontal net is released, that part is completely removed.
It cannot be removed to such an extent that a necessary minimum gap is secured on the wall side. In addition, since the work of binding again after the above-mentioned work is relatively troublesome, the work may be left as it is, and there is a problem in securing safety. The purpose of the present invention is to solve such a problem.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a mounting rod having a male thread portion formed on one side and an engagement recess for rotating operation on the other side, and a moving rod mounted on the mounting rod. The invention proposes a horizontal net tensioning tool which is fitted as possible, and is composed of a set screw and a supporting cylinder body provided with a net supporting member. In the above configuration, the net supporting member can be configured as a ring through which an auxiliary wire for supporting the net passes.

[0005]

In the above construction, the mounting rods are embedded at predetermined intervals along the lateral direction of the wall surface by being embedded in advance in the wall surface of the skeleton or by screwing a male screw portion into an anchor screw that has been punched later. To support the protruding state. The screwing operation of the mounting rod can be performed by engaging a tool such as a wrench with an engagement recess formed on the other side. Next, the support cylinders are fitted to the respective mounting rods, fixed at desired positions with set screws, and the edges of the horizontal net are supported by the net support members.

[0006] If the support cylinder is moved to one side of the mounting rod, that is, to the wall side of the frame, and is fixed with a set screw, the end of the horizontal net can be brought close to the wall to a predetermined tension state. .
Also, if the set screw is loosened and the support cylinder is moved away from the wall surface and fixed again with the set screw at the desired position, a desired gap can be formed between the edge of the horizontal net and the wall surface,
With this gap, it is possible to easily perform the finishing blacking work of the wall surface, the base repair work, and the like. After these operations, the support tubular body is moved to the wall surface side again and fixed, thereby restoring the stretched state of the horizontal net described above.

[0007] If the edge of the horizontal net is fixed via an auxiliary wire passed through a net supporting member formed as an annular body, an adjacent mounting rod is provided at a predetermined fixing interval of the edge. The spacing between them can be widened.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
1 and 2 show an embodiment of the components of the device of the present invention. The mounting rod 1 shown in FIG. 1 has a male screw portion 2 on one side and an engaging recess 3 for rotating operation on the other side. Is formed. If the engaging recess 3 is configured in the same manner as the engaging recess of the foam tie, for example, a tool such as a spanner can be shared.

The support cylinder 4 shown in FIG. 2 has an octagonal column shape, has a fitting hole 5 for loosely fitting into the mounting rod 1, and has a set screw 6 and a net support member 7. In this embodiment, the net supporting member 7 is formed as an annular body, but may be formed into an appropriate structure such as a hook. The set screw 6 is formed by a hexagonal bolt, but may be formed by a suitable structure such as a wing bolt. Of course, the shape and the like of the support cylinder 4 are also appropriate.

FIGS. 3 to 6 show the use state of the device of the present invention. In the figure, reference numeral 8 denotes a wall surface of a frame, and anchor screws 9 are provided at predetermined intervals along a lateral direction of the wall surface 8. This anchor screw 9
Can be installed on the wall surface 8 by post-implantation or can be embedded in the wall surface 8 in advance. Then, the male thread portion 2 is screwed into these anchor screws 9 and tightened, so that the mounting rod 1 is fixed in a protruding state in the lateral direction of the wall surface 8.
At this time, the mounting rod 1 can be rotated by a tool (not shown) such as a wrench engaged with the engagement recess 3 to perform the above screwing and tightening.

Next, the fitting hole 5 of the support cylinder 4 is fitted into the mounting rod 1 protruding from the wall surface 8 in this manner, and the set screw 6 is tightened and fixed at an appropriate position. 4 to 6
As shown in (1), the auxiliary wire 10 is sequentially passed through the ring of the net supporting member 7 at the adjacent position, and is erected. The edge of the horizontal net 11 on the wall surface 8 side is fixed to the auxiliary wire 10. This edge can be fixed at appropriate intervals by tying it to the auxiliary wire 10 or the like. On the other hand, the other edge of the horizontal net 11 is bound and fixed to the building frame.

In the above state, for example, as shown in FIG. 5, if the support cylinder 4 is moved to the wall surface 8 side and fixed with the set screw 6, the edge of the horizontal net 11 approaches the wall surface 8, and It can be in a predetermined stretched state.

When the support cylinder 4 is moved away from the wall surface 8 by loosening the set screw 6, and fixed again with the set screw 6 at a desired position, the end of the horizontal net 11 is moved as shown in FIG. A gap 12 can be formed between the inner wall and the wall surface 8, and the gap 12 facilitates finishing blackout work, groundwork repair work, and the like on the wall surface. The gap 12 can be adjusted depending on the position where the support cylinder 4 is fixed. Therefore, if the gap is adjusted to the minimum necessary for the above operation, the operation can be performed while ensuring safety.

After these operations, the support cylinder 4 is again moved to the wall surface 8 side and fixed by the same operation as described above, so that the above-mentioned predetermined stretched state of the horizontal net 11 is restored. As described above, the horizontal net 11 can be returned to the predetermined stretched state only by changing the fixing position of the support cylinder 4, so that the risk of being left with the gap formed is very small.

[0015]

[Effects of the Invention] The present invention is as described above, and has the following effects. The gap between the edge of the horizontal net and the wall of the skeleton can be adjusted as necessary. Repair work can be performed. Since the operation of returning the horizontal net to the predetermined stretched state is easy, there is very little risk of being left with the gap formed.
