Various composite construction methods called construction methods are often used, and it is desirable that such construction methods ensure a work space as large as possible on the constructed slab. Therefore,
If you support the slab formwork with pipe supports, you can leave the working space as effective as possible on the pre-built slab, but if you do not connect multiple pipe supports, strength will not come out, so this A large number of metal fittings have to be used to clamp the laterally extending single pipes and to bind the braces, which has the drawback that the labor involved is very complicated. Therefore, the present invention is

As shown in FIG. 1, the horizontal brace 10A is not suspended. Among the plurality of composite clamps 11, the composite clamps 11 mounted on the pipe support 7 located in the upper part of FIG. 3 (the row on the arrow D direction side) and the composite clamps 11 located on the lower part of FIG. 3 (the row on the arrow C direction side) are located. The composite clamp 11 mounted on the pipe support 7 is the same, but is used in a state in which the disposing direction is reversed upside down when the composite clamp 11 is fitted and mounted on the pipe support 7. .

Since the structure 1, the formwork scaffold 6 and the composite clamp 11 used for the structure 1 have the above-mentioned constitutions, when the structure 1 is constructed, the constructed slab on the Nth floor is constructed. 2 When the construction is completed, as shown in FIG. 1 or FIG. 2, the space 5 formed on the Nth floor is used to perform the work here, and while the wall 3 is placed, The formwork scaffold 6 for constructing the slab 2'is assembled in the space 5 on the Nth floor. To do this, first, place the two composite clamps 1 at the predetermined level position on each pipe support 7.
1, 11, the distance between the composite clamps 11, 11 is L3
Fit to make. At this time, among the plurality of pipe supports 7, the pipe support 7 for arranging in the row on the arrow C direction side in FIG. 3 and the pipe support 7 for arranging in the row on the arrow D direction side in FIG. 3 are shown in FIG. As in compound clamp 11
Of the pipe support 7 in the insertion portions 120, respectively.
The pipe support 7 is clamped through the bolt 17 and the nut 19 in this state. Then, the composite clamp 11 is provided with the first protrusions 13 in the form of protrusions 13 ₁ and 13 ₂ projecting up and down of the main body 12. If this is used, as shown in FIG. Clamp 11
The first protrusion 13, the second protrusion 15, and the auxiliary second protrusion 1
Each pipe support 7 can be fitted so that 6 is arranged at a position suitable for connecting each brace 10.

In this way, each pipe support 7
The composite clamps 11 and 11 are fitted to each other, and a plurality of pipe supports 7 are connected to each other with the braces 10 by using the composite clamp 11 to construct the pre-assembled slab. We will stand on top of 2. Then, the horizontal brace 10A, the left-right brace 10B, and the inter-row brace 10C of the brace 10 are preliminarily set to predetermined lengths.
By suspending A, 10B, and 10C between the compound clamps 11 and 11 fitted in the predetermined positions of the respective pipe supports 7, the plurality of pipe supports 7 can be moved to the arrow A,
The pitch in the B direction is L1, and the pitch in the C and D directions is L.
It can be easily built into the space 5 on the constructed slab 2 so as to form 2.

By the way, in this way, each pipe support 7
When each brace 10 is suspended between the composite clamps 11, the composite clamp 11 fitted to the pipe support 7 has a first shape protruding upward and downward of the main body 12, as shown in FIG. The protrusions 13 (13 ₁ , 13 ₂ ), the second protrusions 15 protruding from the side surface of the main body 12, and the auxiliary second protrusions 16
However, each brace 10A, 10B,
The shape is such that it is arranged in an orientation suitable for attachment of 10C. Therefore, each brace 10 is formed by using the protrusions 13, 15, and 16.
If the connecting holes 10s and 10s are fitted, the brace 10 can be easily suspended between the composite clamps 11 and 11 without trouble. In this way, the brace 10 can be simply and reliably arranged at a predetermined position and in a predetermined direction without using any metal other than the composite clamp 11 or members such as fastening lines. That is, by this, a plurality of pipe supports 7 can be easily connected. It should be noted that when the braces 10 are thus suspended between the composite clamps 11, the protrusions 1 are not attached to the braces 10.
3, 15, 16 also come out, but the protrusions 13, 15, 16
May be left over if used selectively. Thus, a predetermined number of braces 10 are provided between the predetermined number of pipe supports 7.
Is installed, this completes the assembly of the formwork scaffold 6.

The formwork scaffold 6 thus assembled.
Is designed to support the weight of the slab 2'cast and constructed on the N + 1 floor by the strength of the plurality of pipe supports 7 connected and integrated through the brace 10. From a certain point of view, the number of the pipe supports 7 to be arranged can be far smaller than the number of the columns of the frame scaffolding which is usually used as the formwork scaffolding other than the embodiment. Further, since the pipe support 7 and the braces 10 are rod-shaped members, they do not occupy the space 5 on the Nth floor where the formwork scaffold 6 is assembled, and work materials are placed in the space 5. Or, sufficient space is secured to work here. Therefore, the space 5 can be effectively used to efficiently construct the N + 1th floor slab 2 '.

Therefore, by utilizing the space 5 and turning the handle 73 of the level adjusting mechanism 72 provided on each pipe support 7 here, the height of each pipe support 7 is adjusted to a predetermined level. From
Thick end timbers 25 suspended from a plurality of pipe supports 7
The omnier plate 21 is installed on the formwork scaffolding 6 via the thick corner timber 25. Then, the Omnia plate 21
Since the slab casting space 20 having a shape that matches the slab 2 ′ surface of the N + 1th floor is formed here, if concrete is cast on site in the slab casting space 20 and the concrete and the omnier plate 21 are joined and integrated. , The N + 1 floor slab 2'can be completed easily and properly. Therefore, if the formwork scaffolding 6 is used, sufficient working space is secured in the space 5 on the Nth floor as described above, so that the building 1 can be layered for each floor with good workability. It can be done in a short construction period.

In the embodiment described above, the first protrusion 13 of the composite clamp 11 is the protrusions 13 ₁ and 13 ₂ which are planted so as to project vertically from the main body 12. As shown in FIG. 6, one protrusion 13 has two protrusions on the main body 12.
The protrusions 13 ₃ and 13 ₄ provided at the locations may be used. That is, in the example shown in FIG.
The first projection 13, which is a horizontal member connecting means that can be connected to, is composed of two projections 13 ₃ and 13 ₄ provided at different angular positions with respect to the axial center CT1 of the insertion portion 120. Then, one of the two protrusions 13 ₃ and 13 ₄ becomes the first protrusion to which the horizontal diagonal member is to be attached,
As described above, when the horizontal brace 10A is suspended between the pipe supports 7 and 7, these two protrusions 13 ₃ ,
It is possible to connect the connecting holes 10s of the horizontal brace 10A by selectively using any one of 13 ₄ . That is, the plurality of composite clamps 11 used in the formwork scaffold 6 are attached to the row pipe supports 7 shown in the upper side of FIG. 3 and the plurality of row clamp supports 7 shown in the lower side of FIG. 3 as described above. It can be attached to
The position to which the horizontal brace 10A should be connected is different. However, since the main body 12 of the composite clamp 13 shown in FIG. 6 is provided with the protrusions 13 ₃ and 13 ₄ at two places, in which direction the second protrusion 15 and the third protrusion 16 are directed. However, FIG. 3 upper and lower composite clamps 11, 1
Each one of the protrusions 13 ₃ or 13 ₄ can face each other. Therefore, the horizontal brace 10A can be suitably suspended between the two compound clamps 11 and 11 by utilizing the protrusions 13 ₃ and 13 ₄ .

In the above-described embodiment, the composite clamps 11 attached to the respective intermediate height positions of the plurality of pipe supports 7 and the composite clamps 11 attached to the lower portions are used to provide a space between the horizontal brace 10A and the left and right. The example in which the brace 10B and the inter-row brace 10C are arranged between the composite clamps 11 of all the pipe supports 7 has been described, but the arrangement method of each brace 10 is not limited to this, and a plurality of pipe supports may be provided. It is arbitrary as long as it can bring 7 into a predetermined connected state. Also, in the embodiment,
The structural material connecting tool of the present invention is used as the composite clamp 11 to connect a plurality of pipe supports 7, but the structural material connecting tool uses other structural materials as the main rod and It may be used to connect a plurality of rods. In addition, in the embodiment, the horizontal diagonal member connecting means and the vertical diagonal member connecting means are axially formed first projections 13, second projections 15, auxiliary second projections 16 and the like having the same diameter D1. However, the shape of such a protrusion does not necessarily have to be an axial shape. Further, the horizontal diagonal member connecting means and the vertical diagonal member connecting means do not necessarily have to be projections.

[0020]

As described above, according to the present invention, the main rod member having the main body 12 which can be opened and closed and the main rod member such as the pipe support 7 can be inserted into the main body 12 is inserted. An insertion portion is provided, and the main body 12 has a bolt 17 and a nut 1.
Since the clamp means such as 9 is provided so that the main rod inserted through the main rod insert portion can be grasped and released, and the main body 12 is provided with the horizontal diagonal member connecting means such as the first projection 13, The structural material connector such as the composite clamp 11 is attached to the main rod, and the horizontal brace 10 is attached to the horizontal diagonal member connecting means.
Horizontal diagonal members such as A can be attached. Therefore, if a plurality of main rods having the main body 12 attached to the main rods are vertically installed in such a manner that the main rods inserted through the main rod insertion portions are clamped by the clamp means, the horizontal slant members are connected to each other. The plurality of main rods can be easily connected to each other in the form of connecting and suspending the horizontal diagonal members between the means. Therefore, when it is desired to support the slab formwork by using a main rod material such as a plurality of pipe supports 7, if the structural material connecting tool according to the present invention is used as described above, a large number of metal fittings are used. It is possible to easily connect a plurality of main rods to have a predetermined strength without the trouble of arranging the pipes in the lateral direction and binding the brace. If this is done, it is possible to assemble and stand the slab formwork supporting scaffold by the main rod and the horizontal slant easily with little work.
Then, since the slab formwork supporting scaffold by the main rod and the horizontal diagonal member does not take up a space, an effective working space remains on the constructed slab. As a result, it becomes possible to efficiently proceed with the slab construction, and a great effect is obtained.

Further, in the present invention, the first protrusion 13
The horizontal diagonal member connecting means such as the first protrusions 13 ₁ , 13 ₂ projecting in the first direction (arrow E, F direction) parallel to the axial center CT1 of the main rod member insertion portion such as the insertion portion 120. , 13 ₃ and 13 ₄ , the structural material connector such as the composite clamp 11 has the first protrusions such as the connecting holes 10s formed at both ends of the horizontal diagonal member such as the horizontal brace 10A. 13 ₁ , 13 ₂ ,
The horizontal diagonal members can be connected to each other by being fitted into the parts 13 ₃ and 13 ₄ . Therefore, the structural members such as the main rod can be connected more easily. Also, when the main rod is erected, the axial center CT1 of the structural material connecting tool attached to the main rod is erected.
Are oriented in the vertical direction, the first projections 13 ₁ , 13 ₂ , 13
₃ and 13 ₄ have a shape projecting in a first direction along the vertical direction, whereby a horizontal diagonal member having a shape in which a plurality of main rods are connected diagonally along a horizontal plane is The first protrusions facing each other are securely connected and supported. Therefore, the risk of the horizontal diagonal members coming off the main rod is reduced, and as a result, it is possible to more reliably connect the plurality of main rods.

Further, as described above, the horizontal diagonal member connecting means projects in the first direction parallel to the axial center CT1 of the main rod insertion portion, and the first projections 13 ₁ , 13 ₂ , 13 ₃ , In the case of 13 ₄ , the first protrusions 13 ₁ and 13 ₂ are planted so as to project above and below the main body 12, and when the structural material connector of the present invention is configured, the first protrusion and on the same side be reversed upside down 13 _1, 13 ₂
Can exist. Therefore, if necessary, or without worrying about the vertical direction of the structural material connecting tool, the structural material connecting tool can be used upside down and attached to the main rod. This is because in the case of a structural material connecting tool in which the vertical diagonal member connecting means described later is provided together with the horizontal diagonal member connecting means, the positional relationship of each connecting means can be easily changed by reversing the structural material connecting tool. Because you can make a difference,
Even if several kinds of structural material connecting tools having different positions of the horizontal diagonal member connecting means are not prepared, one structural material connecting tool is turned upside down and used to connect a plurality of main rod members to each other. It is easy to suspend horizontal diagonals and vertical diagonals between them. Therefore, it is easy to manage the structural material connecting tool during construction.

Furthermore, in the present invention, the first protrusions 13 ₃ and 13 ₄ are two protrusions provided at different angular positions with respect to the axial center CT1 of the main rod insertion portion such as the insertion portion 120. With such a configuration, the horizontal diagonal member can be attached to either one of the two protrusions provided at different angular positions. As a result, the work of mounting the structural material connecting tool on the main rod can be facilitated without paying much attention to the position of the horizontal diagonal member connecting means with respect to the main rod. Further, in the case of a structural material connector provided with a vertical diagonal member connecting means and a horizontal diagonal member connecting means, which will be described later,
By simply rotating the structural material connecting tool with respect to the predetermined angle axis CT1, it is possible to easily change the positional relationship of the connecting means. Similar to the case of the first protrusions 13 ₁ and 13 ₂ , one kind of structural material connecting tool does not have to be prepared even if some kinds of structural material connecting tools in which the arrangement positions of the horizontal diagonal member connecting means are different are prepared. It is possible to connect the horizontal diagonal member and the vertical diagonal member by selecting and using one of the first protrusions 13 ₃ and 13 ₄ of the above. Therefore, it is easy to manage the structural material connecting tool during construction.

Further, in the present invention, when the main body 12 is provided with the vertical diagonal member connecting means such as the second projection 15 and the auxiliary second projection 16, the structural material connecting tool such as the composite clamp 11 is provided with the horizontal brace. Horizontal diagonal members such as 10A and vertical diagonal members such as left and right brace 10B and row brace 10C can be simultaneously attached. Then, as described above, the structural rods are attached to the upper and lower two positions of the main rod in a form of holding the main rod inserted into the main rod insertion portion of the main body 12 by the clamp means. If a plurality of vertical slant members are provided upright, the horizontal slant member and the vertical slant member can be bridged between the plurality of main rod members by using the horizontal slant member connecting means and the vertical slant member connecting means. Easy to do. By doing this, it is possible to more firmly connect the plurality of main rods provided upright. Then, when the connecting body of a plurality of main rods is used for the slab formwork supporting scaffold as described above, since the strength of the slab formwork supporting scaffolding is improved, the main rod and the horizontal diagonal member are It is possible to reduce the number of vertical diagonal members to be arranged, which makes it possible to open the working space more widely.

Further, in the present invention, the second protrusion 1
5. When the vertical diagonal member connecting means such as the auxiliary second projection 16 is provided, the vertical diagonal member connecting means is perpendicular to the axial center CT1 of the main rod inserting portion such as the inserting portion 120. The left and right brace 10 is configured as a second protrusion that protrudes in a second direction (arrow A, B direction, arrow C, D direction).
B, it is possible to connect the vertical diagonal members to the vertical diagonal member connecting means by inserting the second protrusions into the holes such as the connecting holes 10s formed at both ends of the vertical diagonal members such as the inter-row brace 10C. I can.
Therefore, as described above, it is easier to bridge the vertical diagonal members between the plurality of main rods and connect the main rods. In addition, a vertical diagonal member that connects a plurality of main rod members in an oblique direction along a vertical plane is a main rod member that is extended vertically because the main rod member is erected. The vertical diagonal member is connected to and supported by the second protrusion projecting in the second direction (that is, the direction along the horizontal direction) perpendicular to the axial center CT1 of the portion, so that the vertical diagonal member is relative to the main rod member. As a result, the risk of disconnection is reduced, and as a result, it is possible to more reliably connect the plurality of main rods.

Furthermore, in the present invention, the second protrusions such as the second protrusion 15 and the auxiliary second protrusion 16 project in directions (arrows A and B directions) orthogonal to each other (arrows C and D directions). If it is configured to have two protrusions provided, the brace 1 between the left and right is attached to the second protrusion formed by the two protrusions.
It is possible to connect two types of vertical diagonal members having different extending directions, such as 0B and inter-row brace 10C. Therefore, as described above, it is possible to easily and surely bridge the horizontal diagonal members between the plurality of main rod members and simultaneously bridge two types of vertical diagonal members having different extending directions. It is possible to connect the main rods more firmly.
