2. Description of the Related Art Conventionally, when assembling a scaffold for supporting a slab formwork, a so-called BT type frame scaffold is used to place the scaffold on a completed slab which has been completed on the lower floor side of the slab to be cast and constructed. The support units of the framework scaffold are assembled in a form arranged at a predetermined pitch. Such a framework scaffold
The arrangement of the support units is adjusted according to the length of the brace used for the assembly, so that the assembly can be easily made to have a predetermined pitch. For this reason, a framework scaffold is assembled on the constructed slab, and a large number of support units connected by braces are erected at pitches corresponding to the length of the braces.

However, in this case, the space between the slab form and the constructed slab is closed by the framework scaffold formed by the brace and the support unit, and the space between the slab form and the constructed slab is closed. It is not possible to secure enough work space on the constructed slab,
There is an inconvenience. Particularly recently, a so-called semi-PC, in which a prefabricated member or a precast concrete member is used for a structure of a structure, and such a member is connected and integrated with another structural member or cast-in-place concrete at a construction site. Various composite construction methods such as the construction method may be employed, and it is desirable that such a construction method ensure a work space as large as possible on the constructed slab. Therefore, if the slab form is supported using a pipe support, a work space as effective as possible can be left on the constructed slab. However, when connecting a plurality of pipe supports in order to connect a plurality of pipes extending in the lateral direction or to arrange braces to reinforce the pipes, the pipe support uses a large number of metal fittings. Clamp pipes and braces in place,
There is a drawback in that it must be bound and the work involved in this is very complicated. Accordingly, the present invention has been made in view of the above circumstances, and provides a structural member connecting tool that connects a pipe support and a single pipe and that can easily arrange a brace.

Since the structure 1 and the formwork scaffold 6 have the above-described structures, when the structure 1 is constructed,
When the construction of the N-story completed slab 2 is completed, as shown in FIG. 1 or FIG. 2, the wall 3 is cast in such a manner that the work is performed using the space 5 formed on the N-th floor. At the same time, a formwork scaffold 6 for constructing the slab 2 ′ on the (N + 1) th floor is assembled in the space 5 on the Nth floor. For this, first, the pipe support 7 and the single pipe 9 are connected by the composite clamp 11 at the member intersection 6a, so that the pipe support 7 is used as a main rod for supporting the slab 2 '. Arrow E indicates the direction of each material axis,
In a state where the single pipe 9 is used as a connecting rod, the plurality of pipe supports 7 are connected by the single pipe 9 in a state where the pipe supports 7 are oriented in the F direction.

Then, in this state, the composite clamp 11 has a single tube insertion space 15s formed by the second fixed portion 15A and the second movable portion 15B, and an arrow A in which the single tube 9 is in the second direction,
It is formed in a form that can be inserted in a state of extending in the B direction.
Therefore, if the single pipe 9 is inserted into the single pipe insertion space 15s by loosening and tightening the bolts 17 and the nuts 19, which are the connecting means of the second movable part 15B to the second fixed part 15A, the pipe can be easily formed. At the intersection 6a, the support 7 and the single pipe 9
The respective axis directions are set in predetermined directions (arrows E and F).
Direction and arrows A and B directions)
The two are connected as shown in FIG. In this way, the assembly of the connecting part of the pipe support 7 and the single pipe 9 on the formwork scaffold 6 is completed irrespective of the arrangement of the braces 10.

When the pipe support 7 and the single pipe 9 are cross-connected as described above, the composite clamp 11 in this state, as shown in FIG. The first projection 13 and the second projection 16 which are the diagonal material connecting means implanted in each of the portions 15A, the first projection having its axis centered in the directions of arrows A and B,
On the other hand, the second projections 16 are arranged with their axes oriented in the directions of arrows E and F, respectively. That is, multiple composites

However, when the arrangement direction of the brace 10 is determined in other directions, the second protrusion 16 is used effectively. In this way, the required number of braces 10 are selectively disposed after the assembly of the pipe support 7 and the single pipe 9 is completed. That is, in order to assemble the connected body of the pipe support 7 and the single pipe 9, it is sufficient that the composite clamp 11 is provided, and the brace 10 is not an essential member for assembling the pipe support 7.
In order to reinforce the connection of the single tube 9 and the single tube 9, only the number of braces 10 of a predetermined strength need be provided. In this way, when a predetermined number of braces 10 are provided as a connecting reinforcing diagonal member on a connected body of the pipe support 7 as the main rod member and the single pipe 9 as the connecting rod member,
Thereby, the assembling of the formwork scaffold 6 is completed.

In the form where 0 is selectively disposed only at necessary places, all the pipe supports 7 are connected diagonally or braces 1 are used to maintain the interval between the pipe supports 7.
0 need not be provided. Thereby, formwork scaffold 6
In the space 5 on the Nth floor where is assembled, the number of braces 10 required for reinforcing the connection between the pipe support 7 and the single pipe 9 is arranged, so that many braces 10 do not become an obstacle, Sufficient space is secured for placing work materials or working here. Therefore,
By effectively using the space 5, the slab 2 'on the (N + 1) th floor can be constructed efficiently.

The height of each pipe support 7 is adjusted to a predetermined level by turning the handle 73 of the level adjusting mechanism 72 provided on each pipe support 7 using the space 5. From
End square material 25 suspended on a plurality of pipe supports 7
Is mounted, and the omnia plate 21 is set on the formwork scaffold 6 via the end-square material 25. Then, the omnia plate 21 becomes
Since the slab casting space 20 is formed here so as to match the slab 2 'plane on the (N + 1) th floor, concrete is cast into the slab casting space 20 on site and the concrete and the omnia plate 21 are joined and integrated. The construction of the slab 2 'on the (N + 1) th floor can be completed simply and appropriately. Therefore, since a sufficient work space is secured in the space 5 on the Nth floor, the building 1 can be efficiently stacked and constructed for each floor.
