Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skeleton building module for a skeleton building operation in a large steel frame laminating method.

[0002]

The laminating method in which the concrete is cast after the assembling of pillars, girders, small beams, deck plates, etc., and then the construction is extended upward while solidifying the frame by floor. In the environment where there is no drop of more than one floor and the approach can be made from the concrete floor, there are many merits such as improvement of the safety of the steel frame construction work and improvement of the efficiency of the welding work and the like.

[0003] However, compared to the construction method that precedes the steel-frame construction method, a process that is easily influenced by the weather, such as welding or concrete casting, is very critical in the frame building process, and there is a disadvantage that it is difficult to adjust the compression of the process. As one of the means for solving the problem in such a laminating method, a method of uniting the horizontal members as much as possible and compressing the steel frame construction cycle until concrete placement is conceivable. However, unitization requires a considerably large temporary assembly yard, which is often difficult to implement on construction sites where there is not enough room, and there is a new problem in that its adoption is also restricted.

An object of the present invention is not to unitize a horizontal member such as a small beam or a deck plate, but to rationalize an operation of mounting a horizontal member by a dedicated horizontal transfer device in a construction area and a large crane for a frame building operation. Another object of the present invention is to provide a new module for constructing a skeleton, which makes it possible to shorten the construction cycle by reducing the load on the structure, and to solve the above-mentioned problems in the above-mentioned laminating method.

[0005]

SUMMARY OF THE INVENTION The present invention according to the above object divides a building plane constructed by a laminating method into a required number of construction areas having the same shape, and has a small beam having a size covering substantially the whole of one construction area. A frame construction module having a transport means used for mounting small members such as deck plates and the like, and which can be collectively moved to the next construction area by a crane or the like in accordance with the framework construction on one floor. A plurality of parallel upper beams, the above-mentioned frame composed of a required number of auxiliary beams provided between the upper beams and integrally joining the upper beams, and in the plane of the construction area supported by the upper beams. It consists of an overhead traveling crane that travels vertically and horizontally, and a mast that is provided below the end of each upper beam and that is installed entirely on a steel beam or a temporary bracket of a steel column. Than it is.

The following effects can be expected from the skeleton-constructing module having such a configuration. Since a horizontal transfer device that covers the entire construction area is provided, work such as installation, rolling, and laying of small members can be greatly reduced, personnel can be reduced, and work time in the construction area can be reduced.

[0007] Vertical (unloading) lifting and horizontal (mounting,
(Swing, laying, etc.) and transportation can be separated, so the load on the large crane can be reduced, and the large crane can be used for other heavy work.

[0008] By supplying a dedicated transfer device in the construction area, it is easy to respond to a change in the installation procedure or a trouble, and an effect of suppressing the operation of a large crane and the entire process can be expected.

[0009] Since the transfer device is of an imaginary type, compared with the case of handling small members using a handling device (for example, a forklift) for traveling on the floor brought into the construction area, consideration is given to the strength of the concrete slab and the floor. Steps, openings and the like are not required. The floor can be used effectively as a temporary material storage yard, and safety benefits can be expected because workers and handling equipment do not intersect in a small area.

It is versatile as a work module with simple transport equipment that can handle large spans, and can be diverted to other uses when not in use. For example, on the ground, it can be used as the work equipment of a site factory such as a rebar pre-assembly or a PC processing yard. In such a case, it is possible to expect a further effect on the improvement of work efficiency and work environment by installing on the ground by adding a rain-curing and wind-curing that can be opened and closed. A mobile device can be provided by providing a mobile device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawing, reference numeral 1 denotes a frame for a frame construction module having a size substantially covering the entire construction area. Three rows of upper beams 11, 11 arranged at equal intervals, and the upper beams 11 , 11 are arranged between both ends and between the intermediate portions, and are composed of four rows of auxiliary beams 12, 12 for integrally joining the upper beams 11, 11.

Reference numeral 13 denotes an overhead traveling crane that travels vertically and horizontally in the plane of the construction area. Reference numeral 14 denotes a mast for installing the entire frame on a steel beam or a temporary bracket of a steel column. It is provided in.

The members of the upper beam 11, the auxiliary beam 12, and the mast portion 14 are made of a lightweight three-dimensional truss material that can be easily assembled and disassembled on site. The overhead traveling crane 1 supported by the upper beams 11, 11
No. 3 is a simple suspension which can be used only for hoisting because only the material to be conveyed is light and the lift for one floor is sufficient. A type overhead crane (hereinafter referred to as a light crane) is used, and a plurality of upper chords of the upper beams 11, 11 can be appropriately adjusted via suspension chains 15, wire ropes, turnbuckles, and other height-adjustable suspension members 15, 15. Suspended at a great pitch.

Since the height of the hanging members 15 can be adjusted, even if the upper beams 11 are bent in the vertical direction, the level of the traveling rail 13a can be easily set. The lower end of the suspension member 15 is attached to the upper part of the rail, and is connected to a joint fitting incorporating a ball joint that can swing in all directions, although not shown in the drawing.

In the embodiment shown in the figures, the upper beams 11,
A traveling rail 13 a is suspended from the lower surface of the vehicle 11. A low-sliding traveling saddle (not shown) that can travel along the rail is inserted into each traveling rail 13a, and this traveling saddle is connected to one rigidized transverse rail 13.
b. At this time, a joint fitting incorporating a ball joint similar to the above is inserted between the lower portion of the traveling saddle and the upper surface of the traversing rail 13b. A trolley 13c is inserted into the traverse rail 13b, and a lifting device such as an electric chain block suspended from, for example, 490 kg is suspended below the trolley 13c.

Unlike the conventional overhead traveling crane, the light crane having the above configuration does not require much installation accuracy of rails and the like, and even if the upper beams 11, 11 are slightly elastically deformed, the suspension members 15, 15, the rails, etc. The greatest feature is that the work can be performed without any trouble because the posture can be changed at the member level.

Upper beam 11, 11 and auxiliary beam 1
The mast portions 14, 14 supporting the frame 1 constituted by the frames 2, 12 are provided with brackets (not shown) for transmitting a load to the upper surface of the upper flange of the girder steel beam 2 previously installed as a frame on the lower surface thereof. I have. The structure between the bracket and the upper flange of the girder steel frame 2 is such that it can be easily joined with a clamp or a pin. Equipped with hardware that can prevent slippage.

A sequence for constructing a skeleton by the laminating method using the skeleton building module having such a configuration is shown in FIG. 3 and thereafter. In this description, the skeleton building module is installed on the girder steel frame 2. However, since the manner of installation does not change even in the case of a temporary bracket of a steel column, the temporary bracket is omitted to avoid redundant description.

FIG. 3 is a perspective view of a building to which the present invention is applied. In this building 5, a case is considered in which a complicated core part of the structure is pre-constructed, and the surrounding wings are divided into eight construction areas and constructed in order. The construction shape of each construction area is a rectangle as shown in FIG. 4, and all constructions are the same. The construction on the Nth floor starts with a steel frame, and a large crane 4 constructs the columns 3 and the girders 2.

The steel frame construction worker moves to the next construction area, but in the construction area where the steel frame is completed, the work of laying small beams and deck plates is performed. At this time, as shown in FIG. 5, the skeleton building module is suspended by a large crane 4 on the existing girder steel frame 2 and is simply installed. After the installation, the light beam crane is used to perform operations such as mounting the small beams 6 and the deck plate 7. Suspension of a slightly heavy member or a long deck plate can be performed using two light cranes. In addition, these operations are performed on a concrete floor, which is a feature of the laminating method, and these operations can be performed safely and efficiently by using a small aerial work vehicle.

On the other hand, the large crane 4 only has to carry out the unloading of the small members during this time, and the unloading of one construction area is completed in a short time, and it becomes possible to use it for the lifting work of other parts. Labor savings can also be expected in the roll-up of floor reinforcement.

When the construction of the beams 6 and the deck plates 7 is completed, the module joules for frame construction are lifted by the large crane 4 and moved collectively to the next construction area, and are relocated to the upper part of the steel beams 2. To use. In addition to the uniting of the frame 1, the mast section 4, and the light, the light crane itself has dimensional flexibility, so the installation position accuracy and overall deformation during the refilling are not so much. Since the user does not need to worry, the work can be performed in a very short time.

As described above, in the module for building a skeleton according to the present invention, since the horizontal transfer device covering the entire construction area is provided, the construction work relating to the small members such as the small beams 6 and the deck plates 7 is greatly saved. It can be used for other heavy work by improving the working time in the construction area and reducing the load on the large crane, and it can respond to changes in the construction procedure and occurrence of troubles, so the operation of the large crane and the entire process Can be expected to have an effect on
Since the transfer device in the construction area is of an imaginary type, there is no need to consider the strength of the concrete slab and to take measures such as steps on the floor and openings.
