Description

[Detailed Description of the Invention] [Object of the Invention] Industrial Application Field The present invention is used at a construction site where materials suspended by a crane can be easily transported to a predetermined floor during the construction of a high-rise building. This relates to the protruding stage.

Conventional technology In the past, when constructing high-rise buildings, materials were transported to a specified floor by a lift to a specified intake stage for the destination floor, and from this stage they were manually transported to the destination location, or by crane. Materials were hung from the intake stage and people placed at the intake stage on each floor were used to hook up and take in the suspended materials, but sometimes the materials fell off the intake stage or people tripped. In addition, even if a protruding stage for taking in materials is provided on each floor, it ultimately becomes inconvenient to take in materials to each floor.

Problems to be Solved by the Invention The present invention aims to provide a protruding stage which can be easily attached to and removed from steel materials forming the walls of high-rise buildings, and which has an extremely simple mechanism for use at construction sites. It is something.

[Structure of the invention]

Means for Solving the Problems In view of the above, the present invention provides a fastener having a substantially U-shaped cross section at the end of the stage main body which is constructed in parallel, and an upper part of the fastener is provided with a bolt. is provided so as to be able to come in and out freely, and the upper surface of the steel material forming the wall surface is pressed and supported by the bolt, and a roller whose one end is fastened to the vertical rod of the stage body is provided on the lower part of the fastener. In order to solve the above-mentioned drawbacks, the above-mentioned drawbacks are solved by providing a protruding stage in which the back surface of the upper piece of the steel material is pressed upwardly by the roller, and a mounting table made of an elastic material is fixed to the other end of the stage main body. It is.

Function: When installing a projecting stage to a target floor at a construction site of a high-rise building, the present invention provides a stage that is installed at the other end of the stage body that is constructed parallel to the upper surface of the steel material that forms the wall surface of the building. A removable bolt is supported by pressure on the upper part of the fastener, which has a substantially U-shaped cross section, and a roller whose one end is fastened to the vertical rod of the stage body is mounted on the upper back surface of the steel material forming the wall surface. By pressing and supporting it upward, it can be easily attached to the steel material forming the wall surface, and it can also be easily removed, allowing it to be attached and carried to the destination floor as needed.

Embodiment An embodiment of the present invention will be described below based on the drawings. Reference numeral 1 denotes a stage main body composed of parallel horizontal rods 2, vertical rods 3, and support rods 4;
A fastener 5 having a substantially U-shaped cross section is provided at the end of the holder.

The fastener 5 is fastened and fixed to the vertical rod 3 with bolts 6 in the front and rear directions, and a bolt 8 is screwed into the upper piece 7 of the fastener 5 so that it can come in and out from below, and the head 9 of the bolt 8 The surface of the upper piece 11 of the steel material 10 made of, for example, H steel, constituting the wall surface is pressed and supported.

In addition, the stage body 1 is attached to the lower piece 12 of the fastener 5.
The back surface of the upper piece 11 of the steel material 10 is pressed upward and supported by a roller 14 whose one end is fastened to the vertical rod 3 with a bolt 13.

15 is an elongated hole into which the bolt 13 is screwed, the support shaft 16 of the roller 14 is provided at an eccentric position so that the roller 14 exerts an eccentric action, and the bolt 13 and the support shaft 16 are integrated with a plate 17. By changing the position of the bolt 13 screwed into the elongated hole 15, the roller 14 also acts as an eccentric roller, and the back surface of the upper piece 11 of the steel material 10 is moved by the roller 14. The stage main body 1 is firmly supported by upward pressure, and is configured to be firmly attached to a steel member 10 forming a wall of a building.

In addition, 18 is a clamp for tightening the connecting rod 19 for forming the horizontal rods 2 in parallel, and 20 is a clamp for tightening and fixing the connecting rod 21 for forming the horizontal rods 2 of the stage body 1 in parallel. It is a clamp that makes you feel uncomfortable.

Reference numeral 22 denotes a pedestal that is integrally fixed with the stage main body 1 on the base plate 23 of the clamp 20;
A mounting table 24 made of an elastic material such as rubber or urethane is fixedly integrated with 2 by bolts 25.

Further, 26, 26a, . . . are rollers installed in the middle part of the horizontal rod 2.

Next, to explain the operation of the protruding stage according to the present invention, the protruding stage 1 has a main body composed of a horizontal rod 2, a vertical rod 3, and a fastener 5, and the upper part of the fastener 5 of the stage main body 1 First, the upper piece 11 of the steel material 10 constituting the wall surface is pressed and supported by a bolt 8 which can be freely moved in and out of the stage body 1, and a flat surface is formed by a roller 14 whose one end is fastened to the vertical rod 3 of the stage body 1. By pressing and supporting the back surface of the upper piece 11 of the steel material 10 upward, the stage main body 1 is firmly fixed to the steel material 10, and on the other hand, a mounting table made of an elastic material such as rubber or urethane is attached to one end of the stage main body 1. 24, the projecting stage according to the present invention can be installed on the destination floor of a high-rise building, and the material suspended by the crane can be transferred to a roller whose end is placed on the mounting table 24 of the stage body 1. 26, the rollers 26, 26
Such materials can be easily incorporated into buildings in a...

〔Effect of the invention〕

In short, the present invention provides a fastener 5 having a substantially U-shaped cross section at the end of the stage main body 1 which is constructed in parallel, and a bolt 8 is provided in the upper piece 7 of the fastener 5 so as to be freely removable. The bolt 8 presses and supports the surface of the upper piece 11 of the steel material 10 that forms the wall surface, and the lower piece 12 of the fastener 5 is attached to the vertical rod 3 of the stage body 1.
A roller 14 with one end fastened is provided, and the roller 14 presses upward and supports the back surface of the upper piece 11 of the steel material 10, so that the fastener 5 of the stage main body 1
The stage main body 1 can be easily and securely fastened to the steel material 12 that forms the wall surface of the building, and can be removed when unnecessary.On the other hand, a mounting base 24 made of an elastic material is fixed to the other end of the stage main body 1. Therefore, even if a heavy material is placed on the roller mechanism section 27, the impact can be greatly reduced, and the overall strength of the stage body 1 can be increased.

In addition, since the stage main body according to the present invention has a basic configuration of horizontal bars 2, vertical bars 3, and fasteners 5, the number of parts is small, and it can be easily installed on site, resulting in low cost. Its practical effects, such as its ability to be manufactured, are enormous.
