Description

[Detailed description of the invention] "Industrial application field" This invention relates to 1-improvement of the labeling method.

``Conventional technology'' The traveling construction method is a method in which a large frame to be erected on a building structure is divided into several blocks, assembled at a location where crane operation is possible, and then moved sequentially by placing them on traveling rails installed on the top of the building structure. This is the way to proceed. The steps are:
First, assemble the divided first block on a stage set up at the end of a pre-constructed 1st block. This is moved laterally by one block using hydraulic jacks, etc., and the next second block is assembled on the empty stage. This method involves sequentially moving laterally and constructing the structure.

The present applicant also proposed this in Japanese Patent Laid-Open No. 57-116847.

In the hammering and traveling construction method, as shown in Figures 2 and 3, a steel truss unit 1 assembled into the ground is placed on the upper end of one gable side of a reinforced concrete frame B that has been constructed in advance. Assemble the scaffolding 3 of the gear rally 2 in an example part of the pusher B so that the truss assembly is possible, and the scaffolding 3
1 unit assembled on the ground 1. . . . is lifted and placed by a crane (not shown) installed on the outside of the frame B,
In addition, the installed units 1.1 are connected to each other. Conventionally, 2. For example, when constructing a steel roof for a large space such as a gymnasium, a large crane is entered inside the building and large-scale temporary construction is carried out under the roof. With shoring.

One method involves assembling a work scaffold and assembling the steel frame on the work scaffold, and the other involves assembling the steel frame in advance and hoisting it up.

Alternatively, the glue-and-bunch-up construction method is known, in which the frame is pushed up, but compared to these conventional construction methods, it reduces the need for temporary scaffolding and reduces construction costs.

By repeating the same work in the same position, it is possible to improve safety and construction accuracy, and shorten the construction period.

In the above figure, 5 indicates a beam, and 6 indicates a moving rail.

``Problems to be solved by the invention'' However, the advantages mentioned above are related to the temporary construction of the steel frame body (roof truss, frame), floor decking, etc.

Finishing work must be carried out using the conventional means described above.

However, it is impossible to shorten the construction period because finishing work will be required after the steel frame work and floor work are completed.

For the finishing work, horizontal and vertical scaffolding is required on the entire surface of the temporary construction site, as well as movable scaffolding, making it difficult to reduce costs accordingly. Furthermore, if full-scale horizontal and vertical scaffolding is required, the radius of action for high-place work in the workplace will be expanded accordingly, requiring careful management in terms of safety.

``Means for Solving the Problems'' and ``Operations'' The present invention was made in view of the above circumstances, and its gist is that the large frame is divided into several blocks and crane operation is possible. In the traveling construction method, which is assembled in a place where it is possible, placed on a traveling rail installed on the top of the 1gX body, and moved sequentially, the frame 1 was assembled and finished on a self-propelled vehicle waiting on the traveling rail. Once the blocks are completed, each block is sequentially transported and set in a predetermined position on the pivot.By eliminating the need for most of the finishing work after traveling, the construction time is shorter than with the conventional traveling construction method. shortening.

This technology is expected to reduce costs, improve construction accuracy, and ensure safe work (reducing the area required for work in high places).

That is, in the construction method of the second invention, a minimum amount of scaffolding (one block of steel frame) is installed around the outer periphery of the building body, and the same goes for the inside.

Thus, one block of steel frame is assembled on the traveling rail on a waiting self-propelled vehicle (not shown).

After the steel frame work is completed, painting, roofing, and dusting work will be carried out, and the exterior walls will also be completed.

Also, with one scaffold, one span can cover both the interior and exterior. In particular, if the internal scaffolding is made into a stage format, it can be used for the final tightening of steel frames, painting, and horizontal curing, and roof work can be done without having to worry about working at heights.

One block of the frame finished in this way.

They are sequentially transported on a self-propelled trolley to a predetermined position on the target and set.

The method of fixing it to a column base is to temporarily raise it to a predetermined height using a hydraulic jack, and once the column base is set in the specified position, lower it one block at a time using hydraulics. The legs may be welded or bolted. The finished part, that is, the roof/exterior wall joint, will be constructed using internal and external movable scaffolding when one block is completely set.

Subsequent blocks of the first order are processed in the same manner.

"Implementation" This will be explained in detail below based on the drawings.

Figures 1a and 1b are plan views of the site where the construction method of the present invention is implemented.

In the side view, 10 in Figure 1 is an external scaffold installed around the outer periphery of the building body 11, and 12 is an internal scaffold installed corresponding to the external scaffold 10.

Reference numerals 13 and 14 are cranes for steel frame assembly and cranes for bringing in steel frames once the ground assembly has been completed.

In the steel frame 1 block 15, steel frame members brought in from the crane 14 are assembled onto a waiting self-propelled vehicle.

Alternatively, the assembled steel frame is received, and further painting, roofing, and sassy work is carried out.

Therefore, in the block 15, 16 indicates a steel frame, and 17 indicates a roof material covering the steel frame 16.

In this way, the structural block, which has undergone finishing work, is completed.

At this time, if the internal scaffolding 12 is made into a stage type, it can be used for final tightening of the steel frame, painting, and horizontal curing, eliminating the image of working at heights.

One block of the finished frame is transported to a predetermined position on a self-propelled trolley (not shown), first temporarily raised to a predetermined height using hydraulic jacks, and then lowered once the column bases are set in the predetermined positions. set.

The legs may be welded or bolted.

The freed self-propelled vehicle returns to work on the construction of the second block.

When such traveling is completed, the finishing work has already been completed in the present invention, so only the connections between the roofs, the exterior walls, and the exterior walls and floors remain. You can do it with

In addition, if the external scaffold 10 is bulky and becomes unstable.

Temporarily install a channel as a guide rail horizontally on the side of the steel frame that has undergone finishing work, and connect it to the moving object by bringing out a connecting bar with sliding rollers, etc. at the tip from the scaffolding and engaging it. Just do it.

As a result, the building will be completed without the need for most of the finishing work after traveling.

"Effects of the Invention" According to the construction method of the present invention as described above, the following effects can be obtained.

i) Compared to conventional construction methods, the process can be shortened by approximately 15%.

ii) Costs can be significantly reduced by requiring temporary staff such as one piece of interior and exterior, vertical and horizontal curing, and cranes.

iii) Safety management is easier because the scope of work at height can be kept to a minimum.

iv) Variations in accuracy can be reduced by repeating the same pattern.
