Description

[Detailed Description of the Invention] The present invention relates to a scaffolding frame bracket that is fixed to a wall of a building to support the scaffolding frame.

Scaffolding frame brackets are useful, for example, when underground construction is delayed and a scaffolding frame for assembling formwork must be erected before backfilling is completed, or when a neighboring house is nearby and the scaffolding frame is installed from the lowest floor. It is used when it is not possible to construct a bridge. However, conventional scaffolding frame brackets are fixed to the steel frame of the building by welding, making it extremely troublesome to fix and remove the brackets.Furthermore, removed brackets leave welding marks, making it difficult to reuse them. unable to
It was uneconomical. In addition, Japanese Utility Model Application Publication No. 58-148131 discloses a bracket-type support scaffolding in which horizontal members and diagonal members are fixed to erected pillars and supported via the horizontal members, but this is not suitable for use on the balcony floor of a building, for example. The upper part was supported by erecting pillars on the top of the structure, which made it impossible to attach it to the side wall of the building, and because the structure lacked a means for directly assembling the scaffolding frame onto it, it was not suitable for use as a scaffolding frame.

The present invention was devised in view of the above-mentioned problems, with the aim of making it easier to fix and remove the scaffolding frame bracket, and to enable reuse.

Furthermore, the basic configuration of the present invention includes at least two
It has a main horizontal member and a diagonal member, and connects the tip of each horizontal member and the tip of the diagonal member at a certain interval, and connects each horizontal member and the diagonal member via a reinforcing material. Connect each other, and attach a connecting plate to the base end of each horizontal member and diagonal member so that it is perpendicular to the horizontal member,
Anchor nuts or anchor bolts installed on the wall surface of a building are connected to each of the connecting plates via a connecting bolt or a connecting nut to removably fix the bracket to the wall surface of the building.

Hereinafter, the present invention will be explained in more detail with reference to Examples.

Figure 1 shows a scaffolding frame bracket B according to the present invention.
It is shown. This bracket is made by connecting two horizontal members 1, diagonal members 2, and a plurality of reinforcing members 3 to each other, and the horizontal members 1, diagonal members 2, and reinforcing members 3 are all made of pipe materials. has been done. The two horizontal members 1 are connected to each other via a plurality of connecting plates 4 at a predetermined interval, and the tips of the two horizontal members 1 and the tip of the diagonal member 2 are connected, A lower horizontal member 1 and a diagonal member 2 are connected to each other via a plurality of reinforcing members 3. Connecting plates 5 and 6 are attached perpendicularly to the horizontal member 1 on the base end surfaces of each horizontal member 1 and diagonal member 2, respectively. A pair of elongated holes 7 and 8 for inserting bolts are provided in each of the connecting plates 5 and 6 in the horizontal and vertical directions, respectively, and the connecting plate 4 that connects the base ends of the horizontal members 1
In this case, when fixing the scaffolding frame fixing tool C, which will be described later, to the two horizontal members 1 via the bolts 16, the bolts 1
A bolt insertion hole 9 for inserting the bolt 6 is provided.

In addition, the scaffolding frame fixing tool C is made of a U-shaped board that is bent into a U-shape, as shown in Figures 4 to 6.
A cylindrical body 11 is connected to a U-shaped member 10. A bolt insertion hole 12 is provided in the center of the opposing plate surfaces of the U-shaped member 10, and a lock pin 13 is attached to the center of the cylindrical body 11.

In order to fix the bracket B having such a configuration to the wall surface W of the building A, the steps shown in FIGS.
As shown in the figure, each connecting plate 5, 6 of the bracket B is directed toward the wall surface W, and each anchor nut 14 buried in the wall surface W is connected to each connecting plate 5, 6 via a connecting bolt 15. , the bracket B is firmly fixed to the wall surface W of the building A. Each connecting plate 5,
6 is perpendicular to the horizontal member 1, so
The horizontal member 1 of the bracket B fixed to the wall surface W becomes horizontal.

In addition, in order to erect the scaffolding frame D using the bracket B fixed to the wall surface W as a supporting material, as shown in FIGS. Fit it on the outside of horizontal material 1,
When the fixing bolts 16 are inserted into the respective bolt holes 9 and 12 and tightened, the scaffold frame fixing tool C is fixed to the end of each horizontal member 1 of the bracket B. Similarly,
A scaffolding frame fixture C is fixed to the tip of each horizontal member 1. The interval between each scaffold frame fixture C corresponds to the width of the scaffold frame D.

Then, insert the lower half of the screw rod 18 of the jack 17 into the cylindrical body 11 of the scaffolding frame fixture C, and
Connect the upper half of the screw rod 18 of the jack 17 to the scaffolding frame D.
is inserted into the vertical member 19, and the lower end surface of the vertical member 19 is brought into contact with the support plate 20 of the jack 17,
When the lock pins 13 and 21 provided on the cylindrical body 11 and the vertical member 19 are connected by the connecting arm 22, the lowermost scaffolding frame D is supported by the bracket B and constructed. Thereafter, the scaffolding frame D is successively erected upward in the same manner as before. Further, when constructing the scaffolding frame D, the screw rod 18 of the jack 17 is raised and lowered to horizontally construct the scaffolding frame D. In addition, in Figure 4, 2
3 indicates a scaffolding board.

Furthermore, the scaffolding frame bracket B according to the present invention is
Since the structure is as described above, as shown in Fig. 2, the bracket B is fixed to the erected scaffolding frame D,
A scaffolding frame D can be further erected on the bracket B fixed to the scaffolding frame D, and the bracket according to the present invention can also be used when constructing a balcony in a building.

In addition, since the horizontal member 1, diagonal member 2, and reinforcing member 3 that constitute the bracket B in the above embodiment are all pipe materials, the bracket B is lightweight.
Each member 1, 2, 3 constituting the bracket B may be a solid member or an angle member. Furthermore, in the above embodiment, the case where the anchor nut 14 is buried in the wall surface W of the building A has been described, but the wall surface W
Anchor bolts may be buried in the

Since the scaffolding frame bracket according to the present invention has the above-described configuration, it can be fixed to a wall surface and removed from the wall surface extremely easily and in a short time, reducing the time required to erect the scaffolding frame. In addition to being extremely economical, the bracket can be reused after being removed.

Furthermore, since at least two horizontal members are provided at a constant interval on the bracket, attachment of the scaffold frame fixing tool becomes easy.

In particular, if each member of the bracket is made of pipe material, the weight of the bracket can be reduced without reducing the strength in use.
