Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffolding for internal scaffolding constructed on the site of a building to be built.

[0002]

2. Description of the Related Art As shown in FIG. 23, as a conventional scaffold of this type used when building a building, an outer scaffold 3 installed so as to surround a foundation 2b of the building to be built.
1 is known. Inside the outer scaffold 31 is a wall panel 2
When hoisting and transporting the building material 20 such as 0a, a large-sized mobile crane equipped with a crane is often used.

[0003]

However, when the conventional outer scaffolding 31 as described above is installed and a large crane vehicle is used for hoisting and transporting the building material 20, when the large crane vehicle is used, road traffic around the site is increased. However, there is a problem in that it causes annoyance to the neighborhood, such as a large amount of noise. In addition, when a large mobile crane cannot enter a position close to the site, it is necessary to lift and transport it over an adjacent house or electric wire, which is very dangerous.

If the building to be built is small,
There is a problem that it is difficult to perform construction work efficiently and it is difficult to shorten the construction period. Further, since many materials for installing the outer scaffold 31 itself, fuel costs for a large-sized mobile crane, and the like are required, it is difficult to reduce the construction cost.

The present invention has been made in view of the above-mentioned problems, and when constructing a building, the construction work can be performed safely and efficiently without disturbing the neighborhood. It is an object of the present invention to provide an inner-group scaffold structure that can shorten the construction period and the construction cost.

[0006]

[Means for Solving the Problems] As means for achieving the above-mentioned object, firstly, there are pillars vertically erected in the site of a building to be built, and on the foundation of the building. And a work scaffold supported so as to connect between the wall panel and the support column.

Secondly, the supporting column is composed of a plurality of supporting column members which are sequentially and removably connected in the longitudinal direction. Thirdly, a crane is installed on the upper end of the column.

Fourthly, the crane has a base body which is detachably fixed to an upper end portion of the support column, a crane support column which is rotatably held on the base body about its axis, and the crane support column. A guide rod fixed to a predetermined height so as to be oriented in a horizontal or substantially horizontal direction, a traveling body held so as to be movable along the guide rod, and a winding transmission mechanism for moving the traveling body. A simple crane in which a flexible member having one end connected to a lifting member and the other end wound around an electric winch attached to the crane column is wound around a pulley attached to the traveling body. Is to be. Fifth, the crane support has a turning handle.

Sixth, the pillars are to be pillars of a building after construction. Seventh, the work scaffold is a floor, ceiling, or beam of a building after construction.

[0010]

According to the first means, since the work scaffold is supported so as to connect between the wall panel and the support, the work scaffold can be secured at a predetermined height, and the construction to be constructed. Inner set scaffolding will be constructed on the site of the thing. Therefore, if the inner scaffold is used, interior work of a building can be performed from the work scaffold. For example, if the support height of the work scaffold is lower than the ceiling of the first floor of the building. The construction work of the first floor ceiling, the first floor beam, or the second floor can be performed from the work scaffold.

According to the second means, since the support pillar is composed of a plurality of support materials which are sequentially and removably connected in the lengthwise direction, one support material is perpendicular to the site of the building to be constructed. If it is erected in the direction, other support members can be connected to the support member so as to sequentially extend upward. By thus connecting the pillar members to form the pillar to a predetermined height, it is possible to support the work scaffold between the pillar and the wall panel, and further connect the pillar materials from the work scaffold to raise the pillar higher. if,
Other work scaffolds can also be supported in higher positions. Thus, by sequentially connecting the support members so as to extend upward, the work scaffold can be supported at a predetermined height, and the support members can be connected further upward from the work scaffold supported at the predetermined height. You can

According to the third means, since the crane is installed at the upper end of the pillar, hoisting of construction materials such as wall panels, floor panels, partition panels, roof panels, beams and columns from the work platform. It can be transported, but since there are no obstacles such as conventional scaffolding, the height of hoisting construction materials can be reduced. Therefore, it is not necessary to use a large-sized crane as long as it has a sufficient function for hoisting and transporting building materials. In this case, if the crane can be assembled and disassembled or can be folded and can be carried on the work scaffold by the force of the worker, the crane can be assembled on the work scaffold and the installation on the column becomes easy. Further, since the support column on which the crane is installed is connected and held to the wall panel via the work scaffold, the lifting and carrying work can be performed in a stable state. here,
If the wall scaffolds are attached to other positions on the base to support the work scaffold between them and the support, the support can be more firmly connected and held from several directions. After building the building, the crane, work scaffold, and stanchions may be removed.

According to the fourth means, since the crane is a simple crane constructed as described above, a power source is required for operating the electric winch in the construction material hoisting and transporting work. , Other operations do not require fuel because they can be done by the power of the operator. Also,
The simple crane is composed of the above-mentioned components and can be assembled and disassembled. Therefore, if the components are disassembled in advance, the crane can be transported on the work scaffold by the force of the worker, and the work scaffolding can be performed. It can be easily assembled and installed on the column. During operation of the simple crane, the crane support is rotated to rotate the guide rod fixed to the crane support, and the winding transmission mechanism is operated to move the traveling body along the guide rod. As a result, the position of the pulley, that is, the position of the hoisting member connected to one end of the flexible strip can be moved to a position where hoisting and hoisting work of building materials can be performed, and the electric winch can be moved. By operating and appropriately winding up or down the flexible strip, the building material can be hoisted and transported to a predetermined position.

According to the fifth means, since the handle for turning is provided on the crane column of the simple crane, the turning operation of the crane column, that is, the guide rod can be easily turned in the intended direction.

According to the sixth means, since the pillar becomes the pillar of the building after construction, it is possible to omit the work of removing the pillar, and also as a pillar for spiral stairs, a space for piping or a ventilation system, etc. It can be used effectively.

According to the seventh means, since the working scaffold is the floor, ceiling, or beam of the building after construction, it is possible to omit the trouble of removing the working scaffold and the columns.

It is also possible to use one of the supported columns 3 and the like, in which case there is an advantage that the number of steps for connecting the column members 3a can be omitted.
The material of the column 3 may be metal or other member, and may be cylindrical or hollow with a hollow central portion. If the central portion is hollow, it can be used for various purposes such as piping and wiring, ventilation, and cooling and heating. Moreover, although the case where only one pillar 3 is erected in the site 2a has been described, the present invention is not limited to this, and two or more pillars 3 are erected in the site 2a and the wall panel 4 is installed. It is possible to support the work scaffold 5 between and the crane 6, and to install the crane 6 such as the simple crane 6 on each of the columns 3. In this case, the work scaffold 5 can be supported so as to connect the columns 3 to each other.

Further, the means for erected the pillars 3 upright in the site 2a is not particularly limited. For example, when the building 22 to be built is large, the foundation 2d is also provided in the site 2a.
In the case where the support member 3 is formed, as shown in FIG. 20, the support member 3a can be screwed to the foundation 2d, or as shown in FIG. 21, the support member 3a is embedded and fixed in advance in the base 2d. , Various techniques can be used. Furthermore, if the wall panel 4 constituting the inner scaffolding 1 is attached to one place on the base 2c, the work scaffold 5 can be supported between the wall panel 4 and the support column 3, but the support column 3 can be operated. In order to more firmly connect and hold the wall panel 4 via the scaffold 5, it is desirable to first attach the wall panel 4 to two or more places on the base 2c as in the above embodiment. Further, as shown in FIG. 22, if the wall panels 4 are first attached to the post 3 at four positions in the substantially cross direction, the posts 3 are more firmly connected and held, and the lifting and carrying work can be performed in a more stable state. You can
