Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lift-up device for a building construction work shed, for example.

[0002]

2. Description of the Related Art A general RC (reinforced concrete) building is constructed by a so-called top-floor preceding construction method in which the building is sequentially constructed toward the upper floor. The construction site on the top floor is constantly exposed to wind and rain, and the environment is extremely hot and cold. As a result, the construction work is easily affected by the weather and the working environment is harsh, so that it is difficult to secure workers.

Conventionally, as a measure for solving such a problem, a fixed-type shed or a horizontally movable shed is installed on the uppermost floor portion under construction, or a lift such as a large lane is lifted. There was a method of raising a shed using an up device.

However, the above-mentioned conventional shed is difficult to apply to tall buildings, and it requires dismantling, moving and assembling using a crane or the like to replace the skeleton, and the equipment is large and There was a problem such as a small opening for loading and unloading equipment.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art. The object of the present invention is to easily assemble and disassemble, and to perform a lift-up operation reliably and promptly. The object is to provide a lift-up device that can perform

[0006]

A lift-up device of the present invention has a guide post along which a lift rail is provided, and a plurality of guide rollers that roll while sandwiching a flange portion of the lift rail. An upper lift unit and a lower lift unit having a tubular portion for inserting and fixing pins according to the holes made in the web portion of the lift rail,
It is characterized by a hydraulic cylinder that connects both lift units in a telescopic manner. Plural holes are made at a fine pitch in the web portion of the lift rail near the lift-up position of the upper lift unit. For example, a traveling rail can be laid on the upper lift unit via a traveling girder, and an openable / closable roof can be mounted on the traveling rail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, A is a building under construction, and a temporary scaffold B is assembled around it. The building A may be of RC construction, SRC (steel-framed reinforced concrete) construction, S (steel-framed) construction, or the like, as long as it is constructed by the top floor preceding construction method. Incidentally, a non-scaffolding construction method in which the temporary scaffold B is omitted may be used.

C is a shed and is a column base 1 of a steel truss.
It is composed of a plurality of portal-shaped frame structural frames 1 composed of a and a roof portion 1b, and a membrane material 2 stretched between the roof portions 1b of these frame structural frames 1, and as a whole, an accordion system. It can be opened and closed. This film material 2 is a permanent film material that has been fireproofed and flameproofed. This membrane material 2
May be stretched between the column bases 1a. Further, in particular, in the heavy snow region, the frame structure frame 1 may be equipped with a snow melting heater to enable snow melting.

As is clear from FIG. 3, of the frame structure frame 1, two frame structure frames 1 at the center and both sides in the opening / closing direction are integrally reinforced by braces 1c. Therefore, the film material 2'in this period is not folded. Incidentally, if there is no risk of falling or the like, reinforcement by these braces is not always necessary, and that of the central portion can be omitted in particular.

By increasing or decreasing the number of the frame structure frames 1, the length of the roof C in the opening / closing direction can be adjusted according to the length of the building A in the girder direction. Further, by increasing or decreasing the truss frame of the roof portion 1b of the frame structure frame 1, it is possible to adjust the span length of the roof C in accordance with the length of the building A in the beam direction. Furthermore, by changing the length of the column base 1a of the frame structure frame 1, the height of the shed C can also be adjusted. Therefore, it can be diverted to another building having a different planar shape and size.

As shown in FIG. 4, traveling wheels 3 are attached to the lower ends of the column bases 1a of the frame structure frame 1 so that they can move while rolling on the traveling rails 4. . Reference numeral 5 is a side roller, which is arranged so as to sandwich the abdomen of the traveling rail 4 from both sides, and is a roof C caused by strong wind or the like.
It prevents the rise of.

The traveling rail 4 is fixed on a traveling girder 6 made of H-shaped steel or the like. The traveling girder 6 is attached to a temporary scaffold B in the girder row direction, as is clear from FIG. When the temporary scaffold B is omitted, it is directly attached to the building A structure. In FIG. 3, reference numeral 6a is a girder receiving bracket to which a height adjusting jack is attached.

Since the roof C of this embodiment is constructed as described above, the frame structure frames 1 on both sides are moved along the running girders 6 from the closed state shown in FIG. 1 (A). When,
Membrane material 2 on the way opens sequentially in an accordion manner,
The fully opened state shown in (B) covers the entire construction site on the top floor of the building A, and the construction can be performed systematically without being affected by wind and rain or temperature.

By partially opening the shed C,
It is also possible to partially open the site and carry in and out work of materials and equipment using a crane or the like. In this way, shed C
Besides opening and closing in an accordion fashion, it is also possible to move as a whole, especially in the closed state. In addition, at the time of normal setting, as shown in FIG. 3, it is fixed to the body of the building A by the wire W.

Next, the lift-up device for the above-mentioned roof C will be described.

As is clear from FIGS. 2 and 3, two guide posts 7 are erected on the outside of the scaffold B in the girder direction, and are connected to the frame A by wall joints 7a. Two
The space between the guide posts 7 of the book is set according to the width of the closed roof C. The number of the guide posts 7 can be increased as needed. In this embodiment,
Although the guide post 7 is installed substantially in the center of the building A, it may be located at any position in the column direction. 7b is a brace.

As shown in an enlarged view in FIG. 5, a lift rail 8 is provided outside the guide post 7.
