Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an all-weather temporary construction frame device for construction.

[0002]

2. Description of the Related Art An all-weather temporary frame has been proposed as a temporary scaffold for the construction of RC high-rise buildings. This temporary frame consists of a number of temporary columns that stand upright around the structure of the building to be built and a roof frame supported between the temporary columns, with an overhead crane on the underside of the roof frame. The materials are placed and lifted by an elevator, etc., and transported to various parts through an overhead crane for assembly. Since the entire top surface of the construction site is covered by the roof frame, it is possible to work regardless of the weather.

For this reason, it is necessary to raise the temporary frame sequentially according to the degree of progress of the construction so that it is always arranged immediately above the construction floor.
As shown in Japanese Patent No. 172, a method has been proposed in which a temporary support column is lifted by a lifting means arranged around a temporary support column (temporary turret) on the ground, and a new support member is added to the lower part.

In addition to this, for example, Japanese Patent Laid-Open No. 5-598.
As shown in Japanese Patent Publication No. 17, a method of raising a work station by arranging a temporary support column with a plurality of telescopic long posts that can be expanded and contracted, arranging a work station on the upper part of the long post, and sequentially feeding out the long posts is also available. Proposed.

[0005]

However, the former invention sets the final weight because the weight of the temporary strut material to be added increases each time the temporary frame is raised and the load of the lifting means increases in sequence. It is necessary to preset the driving force.

On the other hand, in the latter invention, since a full load is applied from the beginning of lifting, a considerable driving force is still required, and the feeding length becomes larger than the accommodated length every time the long posts are sequentially fed. , The support moment at the joint becomes unstable.

Also, in any of the inventions, since the temporary columns themselves move, it is not possible to support them from the building under construction, and the higher the floor is, the more unstable the individual temporary columns become independent. . In order to eliminate self-sustaining instability, it is sufficient to hang braces between each of the temporary columns as a reinforcing material, but not only is the brace work troublesome, but the load increases and it becomes even larger due to lifting. Since it requires power, it was unsuitable as a temporary frame for the construction of buildings with many floors such as skyscrapers.

According to the present invention, the existing apparatus can be effectively used, the driving force for raising the roof frame can be made small, and can be made constant at all times, and the support of the temporary columns can be taken from the building. Therefore, it is an object of the present invention to suppress the bending of the roof frame when the roof frame is lifted and to perform the work of adding the uppermost temporary support pillar without competing with the construction work.

[0009]

DISCLOSURE OF THE INVENTION The present invention is directed to one or a plurality of constructions which are erected close to or within a planned construction position of a building and which are successively added upward in accordance with an increase in construction height. A temporary support, a climbing mechanism that is inserted through the temporary support so that it can be moved up and down, and a jack for raising and lowering is arranged, and a corner support member that is erected on the upper part of the climbing mechanism to form a space for mast connection. And a roof frame connected to the upper portion of the corner support member to cover the entire upper surface of the building, and an overhead crane arranged on the lower surface of the roof frame, wherein the overhead crane has each corner along a crane girder. A sliding crane is provided which is movable to the installation position of the support material and which supports the hoist so that the hoist can travel (claim 1).

A mast of a tower crane can be used as the temporary support (claim 2). The temporary column can be supported on the building side through a horizontal stay (claim 3).

[0011]

According to the structure of claim 1, the temporary support columns are successively added upward, and the existing temporary support columns are fixed as they are. During the climbing work, the climbing mechanism raises the roof frame while supporting the weight of the roof frame only. Temporary support pillars for replenishment are carried and installed to the upper part of the climbing mechanism by a slide-out crane and hoist provided on the overhead crane.

With the structure of claim 2, a support mechanism such as a brace member is not required.

With the structure of claim 3, a climbing mechanism for a tower crane can be applied as the climbing mechanism.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 and 2, a temporary frame device is four masts 2 arranged outside a building 1 to be constructed (only two are shown in the drawings, but in reality, the surroundings of the building 1 are shown. 4), a climbing mechanism 3 attached to each mast 2 so as to be able to move up and down, and a corner support member standing on the upper peripheral edge of each climbing mechanism 3, that is, four corner posts 4 for climbing. The roof frame 5 is provided with a space of a predetermined height between the mechanism 3 and the four corners thereof is fixed, and the roof frame 5 horizontally covers the entire top surface of the building 1 and an overhead crane 6 arranged on the bottom surface of the roof frame 5. .

A freight lift 7 is arranged at the center of one side of the building 1, and materials such as precast members lifted by the lift 7 are transferred to a transfer hoist 8 traveling on an overhead crane 6 and the building 1 Is supplied to each part of.

The mast 2 and the climbing mechanism 3
Is a diversion of a mechanism used for a tower crane. The mast 2 can be selected from a cylindrical columnar body in addition to the trussed columnar body, and is supported by a horizontal stay 9 fixed at one end to the proper building 1 side to be self-supporting. While maintaining stability, the height can be sequentially increased by adding the mast material 2a supplied by the transfer hoist 8 upward in accordance with the rise of the construction floor.

The climbing mechanism 3 has a guide sleeve 3a inserted through the outer periphery of the mast 2 and a guide sleeve 3a.
An upper frame 3b and an intermediate frame 3c that are integrated above and below the mast 2 and surround the periphery of the mast 2, and the intermediate frame 3
Lower frame 3c surrounding the mast 2 at the bottom of c
And a plurality of hydraulic jacks 3e for raising and lowering which connect between both frames 3c and 3d.

Inside each of the frames 3b, 3c, 3d, there are arranged a plurality of guide rollers 10 which roll in contact with the outer portion of the mast 2 as shown in cross section in FIGS. 3 (a)-(c). The frames 3b to 3c are guided so that they can be moved up and down.

The intermediate frame 3c and the lower frame 3d
As shown in FIGS. 2B and 2C, a pair of vertical load supporting pins 11 are inserted into and removable from the mast 2 to support and fix the climbing mechanism 3 around the mast 2.

In the above structure, the climbing mechanism 3
In the stopped state, the hydraulic jack 3e is contracted and each pin 11
Is supported at a predetermined height position of the mast 2.

In order to ascend, the pin 11 of the intermediate frame 3c is pulled out and the hydraulic jack 3e is extended, so that the portion above the intermediate frame 3c rises by the jack stroke. Next, the pin 11 is attached to the intermediate frame 3c.
If the hydraulic jack 3e is contracted after removing the pin 11 of the lower frame 3d after vertically supporting the mast 2 by inserting the lower frame 3d, the lower frame 3d also rises. After that, the pin 11 is inserted to vertically support the lower frame 3d on the mast 2 to complete the lifting work.

In order to raise the roof frame 5 using the above climbing mechanism 3, the four climbing mechanisms 3 are simultaneously moved up after the construction work is interrupted.

At this time, a force for bending the roof frame 4 is generated due to an insufficient rising speed of each part, but the upper frame 3
Since b and the guide roller 10 of the intermediate frame 3c act as reaction force rollers in directions opposite to each other with respect to the inclination direction, the bending of the roof frame 5 can be suppressed. As described above, the force that the roof frame 5 tries to bend is also generated when the overhead crane 6 transfers the material, but the guide roller 10 acts as a reaction force roller to suppress the bending of the roof frame 5. You can

After the ascent is stopped, the load is stored in the mast 2 via the pins 11 so that the four corners of the roof frame 5 are in the mast 2.
It is positioned at the height of and is supported horizontally. After this, construction work can be resumed.

The corner posts 4 are erected at the four corners of the upper frame 3b, and the space surrounded by the corner posts 4 is used as a space for connecting the masts. The transfer hoist 8 conveys it into this space and sequentially installs it.

The overhead crane 6 of the roof frame 5 includes a central fixed rail 6a having one end facing the cargo lift 7 and wide left and right fixed rails 6b arranged parallel to both sides thereof.
And center and left and right crane girders 6c and 6d arranged so as to be able to travel orthogonally to each rail 6a, and a slide-out crane 6e that is movable along the longitudinal direction of the left and right crane girders 6d. The transfer hoist 8 can move along the central crane girder 6c, and can move along the crane girders 6c and 6d in a state where the crane girders 6c and 6d coincide with each other while transferring to the crane 6e.

The crane girders 6c and 6d are traveling ranges that cover the entire area of the building 1 while avoiding interference with the guide posts 4. Therefore, when the construction material is carried in, the transfer hoist 8 has a central rail 6a and Materials are distributed to predetermined positions in the building 1 using the left and right fixed rails 6b.

Further, the transfer hoist 8 which has received the mast member 2a from the cargo lift 7 due to the approaching of the roof frame 5 and the crane girders 6c and 6d are aligned with each other to transfer to the crane 6e.

Next, the crane girder 6d holding the slide-out crane 6e moves on the fixed rail 6b and stops with its end directed toward the space of the corner post 4, and then, as shown by the imaginary lines in FIGS. 1 and 2. The tip of the sliding crane 6e is supplied into the space.

Subsequently, the hoist 8 moves into the space along the slide-out crane 6e and stops at this position, so that the mast member 2a can be installed right above the existing mast 2.

In the above embodiment, since the building 1 has a rectangular cross section, the case in which the masts 2 are arranged at four locations outside the building 1 has been described, but only one to three masts are arranged according to the building cross sectional area. However, of course, the upper part may be covered with a roof frame, and if the cross-sectional area is large, a larger number may be provided.

[0032]

The construction temporary construction frame device of the present invention has the following advantages.

(1) Since the climbing mechanism ascends while lifting the weight of only the roof frame and its accessories during the ascending work, the driving power for raising the temporary frame can be kept small and always constant. .

(2) Since the temporary strut material for replenishment is transported and installed to the upper part of the climbing mechanism through the sliding crane and hoist provided on the overhead crane, the work of replenishing the temporary strut material is also weatherproof.

(3) With the structure of claim 2,
The climbing mechanism can be applied to the tower crane and the existing device can be effectively used.

(4) With the configuration of claim 3,
Since the self-sustaining stability can be obtained without connecting a plurality of braces between the temporary columns, the weight is reduced.
