Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a shaft for carrying equipment materials to each floor during facility construction inside a building, and in particular a shaft that penetrates from the top floor to the bottom floor in a building. The present invention relates to a loading shaft provided with a loading plate opening.

[Conventional technology]

Conventionally, 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 doors and windows installed on each floor to transport materials and equipment. was going on.

[Problem to be solved by the invention]

However, in the above-mentioned conventional construction method, the equipment brought in through the entrance is moved horizontally through the opening, and then suspended or hoisted to a predetermined floor using lifting equipment provided above the opening. For this reason, there is a drawback that it requires a large amount of time and man-hours to bring in materials and equipment.

SUMMARY OF THE INVENTION An object of the present invention is to provide a loading shaft that eliminates the drawbacks of the conventional construction method and facilitates loading of materials and equipment to each floor of a building having multiple floors.

[Means to solve the problem] When installing equipment in a concrete building consisting of multiple floors, we will provide temporary access openings that pass through the upper and lower floors to allow materials and products to be brought in, and In this system, a hatch is provided so that it can be slid open and closed, and by opening and closing the hatch, the cargo receiver is used as a platform, thereby making it possible to easily transport materials carried in through the entrance to the installation floor.

[Effect]

According to the above configuration, when carrying materials and equipment into a concrete structure building consisting of several floors, a board opening is provided that penetrates from the top floor to the bottom floor of the building as a means of reducing lateral movement on each floor. shall be installed during building construction, the sliding hatch on the floor for carrying in materials will be closed, the temporary opening for carrying in materials will be closed, and a platform will be used to receive the goods through the sliding hatch. Materials and equipment placed on the hatch are pulled in from above the entrance of the loading board by the sliding movement of the hatch. Therefore, it is possible to load and unload materials and equipment without having to worry about large-scale work on other floors. Thereafter, the building equipment can be returned to the predetermined design by responding to the equipment installation work and post-casting the openings after the work is completed, so there are no problems such as changes to the building structure.

〔Example〕

FIG. 1 is a cross-sectional view of a concrete building showing a specific embodiment of the carry-in shaft according to the present invention. As shown in this figure, a building 10 as a structure is constructed by pouring concrete, and the slab 12 that partitions each floor of this concrete building 10 has two sections, one above the other, at the same location on each floor, including the roof floor. A temporary carry-in opening 14 is provided in advance.

This can be easily achieved by placing concrete in advance on the slab 12 by using a formwork to remove the portion corresponding to the temporary opening 14 for carrying in the concrete. And each temporary opening 1
A slide hatch 16 is attached to 4, and the slide hatch 16 enables the temporary carry-in opening 14 to be opened and closed. The slide hatch 16 is formed of a steel plate or the like, and is made slidable by a guide rail or the like provided at the edge of the temporary carry-in opening 14. Of course, the slide hatch 16 may be provided with wheels or the like so that it can run and slide. Further, the slide hatch 16 is installed on the floor surface of each slab 12 so that it can be drawn into each floor.

The work of carrying in materials using the carrying shaft configured as described above is performed as follows. First, the material 20 that has been moved by a transport means not described to the position of the carry-in path 18 outside the concrete building 10 is received by the lifting machine 22A or 22B, and then lifted and carried into the concrete building 10 through the temporary carry-in opening 14 at the top. and hang it down to the designated floor.

At this time, all the temporary loading openings 14 are equipped with slide hatches 16 as accessory equipment, so the slide hatches 16 on floors other than those on which the materials 20 are to be brought in are left open so that they do not become an obstacle to the loading of the materials 20. , it is kept closed except when it is being carried in, and is used as a means to close the opening.

The material 20 suspended to the required floor in this manner is loaded onto a transport trolley 24 guided in advance on the slide hatch 16 in order to facilitate transport, and transported to the installation position.

In the above embodiment, the method of carrying in from the roof of the building was explained, but if it is possible to provide a carry-in path that allows entry into the building at an intermediate floor, an opening in the roof floor is not necessary. Dedicated lifting equipment may be provided in the ceiling of the top floor. In this case, use the slide hatch 16 on the floor above the middle floor.
may be left open during hoisting, and the cargo receiver may be closed at times to cover one maximum board width 14.

After the work of transporting the equipment 20 to each floor is completed, the slide hatch 16 is removed and concrete is poured into the temporary transport opening 14 to restore the original structure of the slab 12.

[Effects of the Invention] As explained above, according to the present invention, a temporary loading opening is provided on each floor and loading is performed only by lifting up and down, thereby minimizing lateral movement on each floor and improving loading efficiency. . Moreover,
Since a slide hatch is provided in the temporary loading opening and the cargo receiver is used as a platform, the cargo receiver can be easily operated, and since it can normally be kept closed, it is highly safe.
