Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side frame mounting device for a frame scaffold.

[0002]

2. Description of the Related Art Generally, a frame scaffold to be constructed on a construction site is constructed by arranging a pair of parallel building frames and a horizontal land connecting the upper end portions of the building frames side by side, and placing a cloth board over the adjacent horizontal ground. It is hung on and attached to both sides of the cloth plate with braces that are tensioned by turnbuckles to obtain the necessary structural strength.
In addition, when the lower frame is created, the upper building frame is piled up on the lower building frame through the bonding material to extend the height, and as in the lower case, a cloth board is laid across the horizontal area of the upper building frame. ,
I try to get structural strength by bracing. Further, if necessary, a side frame for preventing a worker from falling is connected to a building frame adjacent on one side of the cloth plate.

As a side frame, it has already been proposed that the side frame is formed at substantially the same height as the building site, and the lower end edge thereof is arranged so as to be positioned at the intermediate height of the building site so as to be supported by the building site. is doing. In this case, for example, as shown in FIG.
A side frame 120 is provided on the upper and lower parts of the building 20, and
A tongue piece 131 for fixing to the tongue piece 1 is provided.
The tip of 31 is fastened with a bolt 133 to a receiving seat 132 provided on the building 111.

Further, an engaging pin 151 protruding toward the joint material 140 is formed at an intermediate height portion of the vertical member 121 of the side frame 120.
Of the side frame 120 is fixed to the joint member 140 by welding, and the receiving fitting 152 from which the engaging pin 151 is disengaged from above is fixed by welding. The intermediate height portion is temporarily supported by the bonding material 140, and the work of fastening the lower tongue piece 131 of the side frame 120 to the lower building 111 with the bolt 130 is facilitated.

Then, the engaging pin 151 receives the fitting 152.
To the side frame 120 on the lower building 111.
By fixing the tongue piece 131 at the bottom of the
The side frame 120 is arranged so that the upper half of the side frame 120 protrudes above the cloth plate 160 that is laid across the horizontal surface 112 of the ten.

[0006]

By the way, the frame scaffold has a place where such a side frame 120 is attached and a place where only the above cross braces are attached, and a receiving seat 132 is attached to a building frame 111 which is used where it is not attached. There is no need to provide it, and the building frame 111 with the receiving seat 132 and the receiving seat 1
It is conceivable to make the bonding material 140 without 32 and use them properly according to the necessity of the side frame 120. However, this idea involves a problem that production control, storage, use, and the like of the building frame 111 become complicated.

Therefore, it is possible to provide a fixing bracket or the like on the side frame so that the side frame can be fixed to a building without a receiving seat. In that case, the side frame protrudes in the lateral direction. Since there is a part that has been made, it may be bulky during transportation.

The present invention has been made in view of the above circumstances, and makes it possible to make a building frame used in a place where a side frame is installed and a building frame used in a place where no side frame is installed in common. At the same time, it is an object of the present invention to provide a means for fixing the side frame to the building site without impairing portability.

[0009]

In order to achieve the above object, the present invention is directed to, for example, as shown in FIGS. 1 (a) and 1 (b), a lateral member 22 of a side frame 2 formed in a hollow tubular shape. An insertion member 6 that is supported so as to be able to move forward and backward in the axial direction, and a fixed metal fitting 3 that is fixed to the end of the insertion member 6 in the advancing direction and that is circumscribed on the building 11 and that is formed in a curved tube shape. Fixing metal fittings 3 on the ground 11
The retracting urging spring 4 that urges the insertion member 6 to be housed in the hollow inside of the lateral member 22 and the building 11 that is inscribed in the fixing metal fitting 3 escapes from the fixing metal fitting 3 To provide a side frame mounting device for a frame scaffolding, which is provided with a gripping member 5 mounted on the tip of the fixing metal fitting 3 for preventing.

Further, in addition to the above-mentioned structure, a stopper 8 for holding the inserted member 6 in a state of being extended from the lateral member 22 is provided against the urging force of the retracting urging spring 4.

[0011]

According to the above construction, when the side frame 2 is fixed to the building 11, the building 11 is inscribed in the fixing metal fitting 3, and the holding member 5 prevents the building land 11 from coming out of the fixing metal fitting 3. When the scaffolding frame is disassembled, the fixing metal fitting 3 is removed from the building 11, and the retracting urging spring 4 causes the insert member 6 to be housed in the hollow inside of the lateral member 22. The lateral projection size of the side frame 2 is reduced.

[0012]

Embodiments of the present invention will be described below in detail with reference to the drawings. A frame scaffold to which an embodiment of the present invention is applied is, for example, as shown in FIG.
And the lateral lands 12 connecting the upper ends of the two territories 11 are arranged side by side, and a plurality of tiers are assembled in the vertical direction. The side frame 2 is attached to the side surfaces of the building frame 1 and the cloth plate 13.

As shown in FIG. 4, the building sites 11 to be assembled up and down are connected coaxially with each other, for example, via a bonding material, and the side frame 2 having substantially the same height as the building site 11 has its lower edge. Building 1 at the height of the center of building 11
It is fixed at 1.

The side frame 2 has a pair of vertical members 21, upper and lower horizontal members 22, and four corner members 23 connecting these members.
And a reinforcing member 24, and at the intermediate height of each vertical member 21, an engaging pin 7 that engages with a metal fitting fixed to the coupling member is provided, and each horizontal member 22 formed in a hollow tubular shape. Inserts 6 supported at the left and right ends so as to be movable back and forth in the axial direction.
The fixing metal fitting 3 fixed to the end portion in the advancing direction is provided.

That is, as shown in FIGS. 1 (a) and 1 (b), at the left end (or right end) of each lateral member 22, an insert member 6 is capable of advancing and retracting in the axial direction of the lateral member 22. The metal fitting 3 is fitted inside, and the fixing metal fitting 3 is welded to the end of the advancing side while being slightly inclined in the vertical direction with respect to the axial direction of the lateral member 22. A retracting urging spring 4 is inserted into the lateral member 22, and the retracting urging spring 4 urges the insert member 6 into the lateral member 22 in the retracting direction.

The fixing metal fitting 3 is formed in a J-shape circumscribing the building 11, and a gripping means 5 constituted by a thumbscrew is screwed into the tip portion thereof. The gripping means 5 is screwed on the fixing metal fitting 3 on the side opposite to the side frame 2 of the building 11 inscribed in the fixing metal fitting 3 so as to be able to advance and retreat in the direction orthogonal to the axis of the building 1. Then, by tightening this, the building 11 that is inscribed in the fixture 3
Is held between the fixture 3 and the gripping means 5, and the building 11
Is prevented from escaping from the fixing fitting 3.

Further, in this embodiment, the gripping means 5 is used.
In order to facilitate the screwing work of the, as shown in FIG. 2, the engagement for fixing the fixing metal fitting 3 urged in the direction away from the building 11 by the retracting urging spring 4 to the extended position. A tool 8 is provided. The engagement tool 8 is composed of a support shaft 6k penetrating the insertion member 6 in the lateral direction and a pin 6p whose center portion is supported by the support shaft 6k. The lower end of the pin 6p protrudes from the side surface of the insertion member 6 and abuts against the end face of the lateral member 22, so that the extended state is maintained against the urging force of the retracting urging spring 4. .

In the above structure, the building frame 1 is assembled,
Further, after the cloth plate 13 is laid across the adjacent horizontal land 12, the side frame 2 is brought in between the required construction sites 11, and the engagement pins 7 are engaged with the metal fittings to place the side frames 2 on the construction site 11. Temporarily support. Further, after that, the fixing metal fitting 3 at the lower end of the side frame 2 is pulled out against the retracting biasing spring 4, and is circumscribed with the building 11 in the lower stage, and then the set screw 5 is tightened to stop the fixing metal fitting 3 and the fixing metal fitting 3. The middle height portion of the lower building 11 is sandwiched by the screw 5.
