Description

Assistance footing for a lift

The present invention relates to an auxiliary scaffold for a lift installed in a building, in order to safely use a lift that moves up and down along a guide rail so that cargo can be transported during construction of a building, by preventing a space accident between a building and a lift. The present invention relates to an auxiliary scaffold that can be installed and used in a building to prevent a back.

[Document 1] Korea Utility Model Registration No. 0418880, 2006.06.08

As a building is constructed, lifts are used to move workers and various building materials and facilities to higher floors. Such a lift is a structure that is vertically elevated along the guide rail installed on the outer wall of the building, it is a structure that can be stopped for each floor.

The outer wall of the building and the lift must be adjacent so that there is no space so that access to the lift can be safe and easy to work. However, due to the structure of the building and the installation structure of the lift, a certain space is formed between the outer wall of the building and the lift.

Therefore, in order to enter the lift in each floor, a conventional scaffold was installed on the lift. And the scaffold is installed in a rotational manner, and stored in the interior of the lift during operation, and when the work is stopped on each floor, it is flipped to connect the lift and the interlayer slab to eliminate the space between.

However, when a large amount of material is loaded on the lift, it is inconvenient to store the scaffold, and it is inconvenient to install the scaffold between floors, so that the worker may jump over the scaffold to the building and accidentally fall.

In some cases, the scaffold is not installed on a lift but installed on an interlayer slab of a building. In this case, as disclosed in [Document 1], the scaffold is made of synthetic resin, and the bottom surface of the scaffold is polished with a grinder, and a strong adhesive is applied thereto to attach to the building floor layer.

In this case, work such as polishing the scaffolding and the bottom surface is inconvenient, and there is a problem that the fixing means by the adhesive is unstable and not firm.

An object of the present invention is to provide a scaffold that can be installed and used on each floor slab of a building. Such scaffolding is composed of a bracket which is installed in contact with the slab, a pressing device and a fixture that is installed on the bracket to fix the bracket, and a flat plate fixed to the bracket. The bracket is possible in various forms according to the structure of the slab, and has a structure that is adjusted to the spacing between the flat plate and the lift.

According to the present invention, by providing a scaffold that can be firmly installed on the slab, it is possible to use the lift safely, and can be easily dismantled even when the lift is dismantled, between the shape of the slab according to the structure of the building or between the lift and the building There is an advantage that can be used to adjust the size of the space.

The present invention is installed at the end of the slab 50 of the building, it is a safety device that prevents the space between the interlayer slab 50 and the lift (60). The auxiliary scaffold 100 as such a safety device is a flat plate (1); A pair of brackets (2a) disposed below the plate (1) at intervals equal to the thickness of the step (51) formed to protrude above the end of the slab (50); Compression fastener (3) is fastened to any one of the bracket (2a) is pressed to the inside; is configured to include.

And in the case of the flat form without the step 51 in the slab 50, the flat plate (1); A bracket (2b) installed at a lower portion of the flat plate (1) and having a "c" shape in which an end portion of the slab is inserted; It is configured to include; a pressure holding device (3) fastened to the lower portion of the bracket (2b) and pressed into the inside.

The flat plate 1 is composed of one fixing plate 4 provided with brackets 2a and 2b; It may be composed of a fixed plate (4) provided with brackets (2a) (2b), and a moving plate (5) installed to be inserted into or withdrawn from the fixed plate (4) to vary the overall width.

One end of the brace rod 6 is fastened to the bottom end of the end of the fixed plate 4 or the movable plate 5, and the other end of the brace rod 6 is fastened to the slab 50 and fixed plate ( 4) or may be configured to support a load applied to the movable plate 5.

In addition, the brace 6 is made of a structure such as a turn buckle, the length is adjusted, it is configured to effectively support the load by adjusting the length according to the installation state.

The present invention having such a configuration can prevent the fall accident by blocking the space between the lift 60 and the slab 50 as shown in FIG.

In the structure of the interlayer slab 50 of the building, as shown in FIGS. 1 to 6, the end may have a stepped protrusion 51, and as shown in FIG. 7, the step may be flat without the stepped 51. Therefore, the present invention has a different structure of the bracket (2a) (2b) according to the end structure of the slab (50).

First, a case in which the step 51 is provided on the slab 50 as illustrated in FIGS. 1 to 6 will be described below.

Since the brackets 2a are fixed to the lower portion of the flat plate 1 at intervals as much as the thickness of the step 51, the auxiliary footrest 100 is fixed when the brackets 2a are inserted into the step 51. . And in order to securely fixed, the pressure holding device (3) is provided on the bracket (2a) of one side, the pressure holding device (3) by operating firmly fixed. The holding member 3 has a screw type, and has a structure of being pushed to the step 51 by rotation. Of course, in addition to the screw type, any structure for holding the step 51 is possible. And in order to fix the bracket (2a) to the step (51) may be provided with a fixture (7) such as anchor bolts.

The flat plate 1 is composed of one fixing plate 4, and the size of the fixing plate 4 is determined, so that the space between the lift 60 and the slab 50 must be known in advance. As such, the distance adjustment to some extent can be adjusted by the interval between the pair of brackets (2a), and the braces (3) fastened thereto.

The flat plate 1 protrudes toward the lift 60 and may be deformed due to the support load. Therefore, the brace 6 can be installed as shown in FIG. In the case of FIG. 5, the turn buckle is used as the brace 6, and its length can be adjusted by rotation.

The brace 6 is fixed to the slab 50 side, the end of the brace 6 may be fastened directly to the slab 50 or to the bracket (2a), a separate device as shown in FIG. May be installed on the slab 50, and the end of the brace 6 may be fastened to the device.

As described above, since the flat plate 1 made of one fixing plate 4 may have a limit in the range of blocking the space between the lift 60 and the slab 50, the flat plate 1 having a variable width as shown in FIG. 6. It can be implemented in the structure of). In this case, the flat plate 1 is constituted by the fixed plate 4 fixed by the bracket 2a and the moving plate 5 inserted and drawn out into the fixed plate 4. And one side of the brace 6 is fastened to the moving plate 5 is a structure in which the length of the brace 6 is also adjusted according to the movement of the movable plate (5).

In this way, when the moving plate 5 is provided, the space between the lift 60 and the slab 50 can be properly prevented by the movement of the moving plate 5.

Next, the flat case without the stepped slab 50 will be described with reference to FIG. 7 as an example.

In this case, the structure of the flat plate 1, that is, one fixed plate 4 or the fixed plate 4 and the movable plate 5 is the same, and the support 6 is also the same. However, since it is not possible to install and use the vertical bracket (2a) on the flat plate 1, it is used when the "c" type bracket (2b) is attached.

Therefore, the end of the slab 50 may be provided in the opening of the bracket 2b, and the pressure holding device 3 installed in the lower portion of the bracket 2b may be turned to press and firmly fix it. In addition, a fastener 7 such as an anchor bolt, which is planted in the slab 50 through the flat plate 1 and the bracket 2b, may be installed to secure the flat plate 1 and the bracket 2b. Of course, it is only necessary to fasten the end portion 6 to one end of the bracket 2b.
