Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a method for transporting equipment materials to each floor during equipment construction within a building, and particularly relates to a method for transporting equipment materials in parallel with concrete building construction. This invention relates to a loading shaft construction method that makes it possible to construct equipment.

[Prior Art] Generally, when installing internal equipment in a concrete building consisting of multiple floors, the building itself is constructed, and then the equipment and devices to be installed on each floor are brought in and installed. The conventional construction method for transporting such materials to each floor of a concrete building is to use openings in permanent equipment such as door openings and windows installed on each floor to transport materials and equipment. That's what I was doing. In addition, with this type of material delivery construction method, even if a board door for delivery was provided on each floor of a building consisting of several floors, materials were brought in and lifted using a lifting machine outside the building.

[Problem to be solved by the invention]

However, with conventional construction methods, internal equipment cannot be brought in until after the building itself is completed, which poses the problem of prolonging the work period until final completion. In addition, a lifting machine for loading and unloading must be provided at all times.1. In addition, a movable opening/closing stage is required as equipment that can open the loading board opening provided on each floor when materials are passing through and close them on the floor where materials are needed.

The present invention has focused on the problems of the conventional construction method, and has developed a transport system that can be used to transport materials to each floor according to the progress of the building without requiring any lifting equipment or movable opening/closing stage equipment. We provide shaft construction methods.

(Means for Solving the Problems) This invention focuses on the fact that concrete buildings are poured in stages, and provides a board opening at the same location on each floor for a loading elevator to pass through when each floor is poured. The guide rails for the lifting equipment are extended to the upper floors according to the progress of the building construction equipment process, so that the elevator can be moved to the upper floors.In other words, equipment installation work in a multi-story concrete building. During construction, materials and
A temporary loading opening that penetrates the upper and lower floors to serve as a loading path for products will be provided in the floor panel, and a lifting guide rail that will reach the temporary loading opening up to the existing floor panel and a lift that will move up and down this guide rail will be installed in this temporary loading opening, and a lift will be installed to raise and lower the rail. The guide rail was designed to be extended upwards in stages according to the progress of concrete pouring, and to be used as material transport equipment from the top floor to the bottom floor of the building when the concrete building was completed.

[Operation] According to the above configuration, the construction of the concrete building is carried out from the ground side toward the upper floors, but at that time, temporary loading openings are set that penetrate through the upper and lower floors, and temporary loading openings are opened sequentially from the existing floorboard. will be established. This temporary loading opening has a lifting guide rail leading to the existing temporary loading opening above, and a lift 1 guided by this guide rail.
Since the construction is extended upward as the construction of the building progresses, the materials needed for each floor can be brought in sequentially to the lower floors as the construction of the building progresses. This makes it possible to complete the delivery of materials to the lower floors when the building is completed. Therefore, the work for carrying in materials can be carried out in parallel with building construction, thereby shortening the work period. Furthermore, since the materials are carried in using the elevating guide rail and lift, equipment such as a lifting machine for lifting and lowering is not required, and equipment costs can also be reduced.

〔Example〕

Hereinafter, specific embodiments of the loading shaft construction method according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a sectional view of a building using the loading shaft construction method according to the embodiment. This shows the final completed state of this loading shaft construction method, and examples up to this state will be described.

After the foundation work of the concrete building 10 is completed, a floor plate 12 and walls 14 are sequentially poured from the lowest layer side.

After the first floor is poured and constructed, the second floor slab 12 is poured and formed, but at this time, the position where the upper and lower parts can be penetrated when the top floor is constructed is set in advance, and the position of the set point is set. A temporary loading opening 16 is provided in the floorboard 12. This is the floor plate 12 in advance.
This can be easily achieved by pouring concrete using a formwork except for the portion corresponding to the temporary loading opening 16.

After the second floor floor panel 12 is completed in this way, a guide rail 18 for lifting equipment connecting the temporary loading opening 16 on the first floor and the second floor is supported by the building floor panel 12 or wall 14 and installed. This guide rail 18 may be located and attached to one edge side of the temporary carry-in opening 16, and may have a parallel two-striped rail structure.

This guide rail 18 includes a fall prevention device (not shown).
A lift 20 equipped with the like is attached so as to be movable up and down along a guide rail 18. The lift 20 is equipped with a drive device 22, and can be moved up and down by, for example, a gear mechanism.

Of course, other mechanisms such as an elevator mechanism can also be used for the lifting/lowering drive. This constitutes a loading facility that can be moved up and down between the second floor and the first floor. In addition, in the figure, 24 is a protective shelf provided around the temporary carry-in opening 16, and 26 is a hatch that covers the uppermost temporary carry-in opening 16.

The guide rails 18 are successively added to the upper floors as the building construction process progresses, and eventually the elevating equipment up to the top floor is constructed.

Incidentally, the temporary carry-in opening 16 may finally be made into the original structure of the floor plate 12 by pouring concrete.

In the carrying-in shaft construction method using lifting equipment configured in this way, as the concrete building 10 is constructed from the ground floor, communication between the first and second floors is initially possible, and materials for interior equipment to the second floor can be transferred. According to the construction progress of the concrete building 10, it becomes possible to sequentially transport the materials to the upper floors.

Therefore, in parallel with the construction work of the concrete building 10, materials can be carried in sequentially from the completed lower floors. Moreover, since materials are carried in by the action of the guide rail 18 and the lift 20 that raises and lowers the guide rail, a lifting machine outside the concrete building 10 is not required.

〔Effect of the invention〕

As explained above, according to the present invention, in the carrying-in shaft construction method for concrete building equipment installation work, materials can be carried in by a single piece of equipment, so the work can be carried out without external constraints. , materials can be delivered to each floor in parallel with the construction of the building, resulting in the effect of significantly shortening the work period.
