Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a steel assembly device for a building in which a steel beam is assembled to a steel column member or a reinforced concrete column member of the building.

[0002]

[Prior art]

 For example, when assembling each floor in the construction work of a steel frame high-rise building or a reinforced concrete column steel beam, as shown in Fig. 3, first, a steel frame member or a reinforced concrete column member (1) is placed on a floor plan. Standing at the four corners, put the end of the steel beam (2) on the mounting protrusion (1a) provided on the side of the column and tighten it with the bolt (3) so as to bridge between adjacent column members. The beam (2) is assembled to the column member (1). Next, the beam (4) is assembled in a bridging manner between the opposing beams (2), and the floor is placed on the beam (4), and the beams are sequentially assembled. To assemble the high floor. Alternatively, the column member (1) is erected on the existing floor and the beam (2) is assembled, and the floor is similarly assembled.

Here, when assembling the beam (2) to the column member (1), the beam (2) is lifted by a crane truck (not shown) and transported to the standing position of the column member (1). Therefore, as described above, the beam (2) is fastened and fixed to the predetermined portion of the column member (1) with the bolt (3).

[0004]

[Problems to be solved by the invention]

 When assembling steel beams by crane work, the crane truck transports the beam (2) to a different assembling position each time, so crane handling work such as turning and bypassing obstacles becomes very troublesome, and turning in narrow places. Is also difficult, and the work efficiency is greatly reduced. Also, in a building with a large construction area, a large crane is required irrespective of the weight of the load due to the large working radius.

[0005] An object of the present invention is to provide a steel material assembling apparatus for a building in which a steel beam can be mounted on a steel column member without using a crane.

[0006]

[Means for Solving the Problems]

 In the present invention, an air-floating base that can be lifted by air pressure on an air skate on the floor surface and slidably moved without frictional resistance in a horizontal direction, and is installed at a predetermined position on the base so as to be movable up and down. One or more lifters, an elevator mounted and fixed on the lifter, and driven up and down by the lifter; and an air skate that floats on the elevator by air pressure and slides horizontally without frictional resistance; And an air-floating carrier for carrying the assembly steel material on the upper surface and transporting the assembly in the horizontal direction. The steel material is placed on the carrier, and the base, the carrier, and the elevator are slid and moved. Then, the steel material is transported to the existing member to be assembled, and is assembled and fixed to a predetermined portion.

[0007]

[Embodiment of the invention]

 An embodiment of the steel material assembling apparatus for a building according to the present invention will be described below with reference to FIGS. 1 (a) and 1 (b) and FIG. First, FIG. 1A shows a longitudinal sectional view of a steel material assembling apparatus (A) according to the present invention, in which (5) is a base, (6) is a lifter, (7) is a lifting platform, and (8). Is a carriage.

In the base (5), a single commercially available air skate (9) is mounted at a predetermined position on the lower surface of the flat moving body (5a), and the moving body (5a) is supported by the air skate (9). It can be lifted by air pressure with an air skate (9) and can slide horizontally on the existing floor (10) without frictional resistance, and can carry large heavy objects with very little force.

In the air skate (9), an endless cushion material (9b), for example, an endless rubber material is adhered and fixed to the lower surface of the disc (9a), and the air skate (9) is fixed to the floor (10) and the disc (9a). A pressure zone (11) is formed in between, and a flexible air supply pipe (13a) is connected to an air skate (9) from an air pump (12) arranged on a moving body (5a). When air is supplied from the air pump (12) to the air skate (9), the control air (M) leaks from the pressure zone (11) to the atmosphere and a thin air film is formed between the cushion material (9b) and the floor surface (10). Is formed, and the base (5) floats on the existing floor (10) by air pressure. The base (5) can slide horizontally on the floor (10) without frictional resistance, and can move in any direction with very little force.

[0010] The lifter (6) is a pair of pantograph structures which are installed at the left and right positions on the base (5) so as to be able to move up and down. A hydraulic cylinder and a ball screw (ball screw) are used as the elevating mechanism. A vertical movement mechanism may be used, and the number of installations is not limited to one pair, and may be installed at three or four points on the base. Further, a single lifter (6) may be used as in a steel material assembling apparatus (A ') shown in FIG.

The lift (7) is a flat support mounted and fixed on the lifter (6), and is driven up and down by the lifter (6).

The carrier (8) is on the elevator (7), and a single commercially available air skate (14) is mounted at a predetermined position on the lower surface of the flat moving body (8a). ) Supports the moving body (8a), and can be lifted by air pressure by the air skate (14) and can slide horizontally on the elevating platform (7) without frictional resistance. Can be transported. When the air skate (14) is connected to a flexible air supply pipe (13b) from the air pump (12) on the base (5) and supplied with air, the carrier (8) is air-pressured on the lift (7). And can slide horizontally without frictional resistance.

The operation of the present invention based on the above configuration will now be described. First, as shown in Figs. 1 (a) and 2, a steel or reinforced concrete column member (1) is erected at the four corners of the planned floor, and the book is placed in the area surrounded by the column member (1). The steel material assembling device (A) or (A ') according to the invention is arranged, and the steel beam (2) is placed on the carriage (8) by a crane truck or the like. At this time, if the beam (2) is mounted on the steel assembling device (A) or (A ') at a substantially fixed position, the crane truck only needs to repeatedly transport the beam (2) to the fixed position. Thus, there is no need to transport the vehicle to various different positions and directions. Therefore, for example, even if the crane truck is in a fixed position, the work of circumventing obstacles and turning work is unnecessary or reduced, and the work of manipulating the crane is greatly simplified. It is enough to prepare only a minimum number of cranes.

Therefore, the base (5) and the elevating platform (7) are horizontally slid and moved up and down, respectively, and the beam (2) is moved to a predetermined position and height. Next, the carrier (8) is horizontally slid on the elevator (7) to transport the beam (2) to the protruding portion (1a) of the column member (1), and tighten the bolt (3) as in the conventional case. To assemble.

At this time, since the base (5) and the carriage (8) slide without frictional resistance, the operator moves the base (5) by hand, such as hooking a string and dragging it together to form the beam (2). It can be transported to the attachment site, which simplifies work and greatly improves efficiency.

If several steel material assembling apparatuses (A) or (A ') are used, simultaneous or continuous assembling work becomes possible, and the working efficiency is further improved.

[0017]

[Effect of the invention]

 According to the present invention, when assembling a steel beam to a steel column or a reinforced concrete column member of a building, the steel assembling device according to the present invention is arranged on the floor surface and mounted on the air-floating carrier. The beam is mounted on a crane truck, etc., the air-floating base and the carriage are slid without frictional resistance, and the elevator is moved up and down to transport the beam to the member to be assembled and assemble it at the assembly site. Therefore, the required number of cranes and the handling work can be greatly simplified, and the beam can be manually transported to the assembly site, greatly improving work efficiency.
