Abstract

PROBLEM TO BE SOLVED: To provide a safe and economical girder type supporter for supporting a shovel type excavator when suspending the shovel type excavator to an upper layer to perform a work in the disassembling of a reinforced concrete building, a steel framed building or the like. SOLUTION: This support device comprises a H-shaped sectional girder frame 1 formed in a required length, and a workbench surface 2 located in the central part of the frame 1 and having slip stoppers 3 protrusively welded thereto, so that the caterpillar 6 of the shovel type excavator 9 is placed thereon so as to be longitudinally movable and inclinedly movable. The frame is longitudinally set through support boards 5a and 5b having reinforcement bars 4a and 4b welded and fixed thereto, and a tension is generated in the workbench surface 2 by the pressure by fastening of nuts 13a and 13b to entirely enhance the strength, whereby the vibration or heavy pressure of the shovel type excavator 9 is supported.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This type of technology is used in concrete or steel-framed buildings for demolishing work for the purpose of building life or development. This refers to temporary safety materials for basic safety of demolition construction methods used when there is no available place or when the building is high.In such demolition work, a shovel machine is placed on a rooftop slab and cooled. In general, a method of lifting the floor and performing dismantling work from the upper layer to the lower layer is performed. The present invention relates to the technology of a support member that supports a shovel machine because the weight of the shovel machine accompanying the demolition work may affect the slab and the floor of each floor due to heavy-pressure vibration and the floor strength may not be able to withstand and collapse.

[0002]

2. Description of the Related Art Conventionally, as a reinforcing device capable of withstanding the strength of a floor due to the heavy pressure of a shovel machine accompanying such dismantling work, a spiral type called a supporter, which is vertically mounted between a floor and a ceiling, is used. There is one that supports and turns the helical screw to generate tension by the expansion and contraction mechanism of the main body, thereby reinforcing the strength of the floor.

[0003]

[0006] However, as shown in FIG.
Using the method of 1), the ceiling is supported by tension by applying a spiral resistance vertically between the floor (16) and the ceiling, and a large amount of support is installed between the floor and the ceiling on each floor. Since the required amount per floor area and the same amount of installation on the vertical line of each floor are required, the construction period and cost burden are large, and if the floor on each floor does not have the same structure when examined from the safety aspect, The problem of determining the proper position of the spiral support (11), and the screws of the spiral support (11) are often loosened due to the vibration and shaking of the shovel machine (9) during work, causing cracks and loosening under the floor. This requires frequent inspections and repairs, and if left unchecked, there is a problem that the floor may be weakened and fall down.

[0004]

SUMMARY OF THE INVENTION The present invention is a means for distributing the weight of an excavator for dismantling on a beam having a structure relatively stronger than a floor due to the structure of a building.

A beam (10a) and a beam (10) shown in FIG.
During b), a pair of left and right girder-type support devices having an H-shaped cross section and having a required length are provided in a pair, and a cababila (6) on both sides of a shovel machine (9) is mounted thereon. The arm (7) can be turned and the catabila (6) can be moved back and forth without applying pressure to the floor (16).
The purpose of demolition work has been achieved.

Further, a non-slip (3) protrudes from the worktable surface (2) to maintain safety by preventing the catabira (6) from safely landing and slipping when moving. .

In addition, inside the lower part of these girder frames (1), reinforcing bars (4a) and (4b) are provided via support plates (5a) and (5b), which are welded and fixed to the main body in the longitudinal direction. ,
By applying a tightening pressure from both sides with the nut (13), the reaction force generates tension on the worktable surface (2), and a reinforcing device for supporting the heavy pressure of the shovel machine (9) applied thereon is provided. I have.

[0008] Such a girder type support uses two sets to enable the excavator machine (9) to freely move in a plane or to move down to a lower layer, thereby enabling construction purposes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view of a girder-type support device showing one embodiment of the present invention, FIG. 2 is an exploded perspective view of the girder-type support device of the present invention, and FIG. FIG. 4 is a side view of an image of a use condition at a site, and FIG. 5 is a top view of an image viewed from the top in a use condition of the site.

1 is a perspective view showing one side of a girder-type support device of the present invention. As shown in FIG. 1, two girder frames (1) each having a long H-shaped cross section are provided. In this configuration, the cabellas (6) on both sides of the shovel machine (9) are mounted.

Based on the exploded perspective view of FIG. 2, the function will be described in detail by part. The girder frame (1) having an H-shaped cross section and having a required long shape, and the surface of this central part is worked. For the purpose of securing safety during the movement of the catabira (6), the anti-slip (3) can be welded and fixed to the floor (2) to enable flat movement and tilting movement to the lower layer. The goal is achieved without burden.

FIG. 3 shows a reinforcement frame (4) having a required size as a means for increasing the strength of the girder frame (1) as a whole.
a) and (4b) are tightened with nuts (13a) and (13b) through support plates (5a) and (5b) which are previously welded and fixed to the lower part of the girder frame (1) of the main body. And a mechanism for generating tension on the worktable surface (2). To describe these dynamic correlations in detail,
The total weight of the excavator (9) acts in the vertical direction when expressed by the gravity vector (20), and is distributed to the contact area between the catavil (6) and the work surface (2), and the girder frame (1)
Are concentrated at both ends of the beam, and are divided into the beam (10a) side and the (10b) side. Since the pressure of such a total weight is concentrated on both ends of the girder frame (1), there is a possibility of loosening, and it is necessary to reinforce this part in order to ensure safety. Two reinforcing bars (4a) and (4b) used as means for reinforcing the entire girder frame (1) are passed through support plates (5a) and (5b) in the longitudinal direction and nuts (13a) and (13b). Are tightened from both ends, the pressure vectors (20a) and (20b) become
Generates a compressive force at the lower part of the repulsive force vector (22).
a) and (22b) act to generate tension on the central workbench surface (2), thereby enhancing the strength of this surface.

FIG. 4 shows that the excavator (9) is mounted on the workbench surface (2) at the site of the building by means of a girder support on the beams (10a) and (10b) at the upper part of the building. It is a side view which images a state. As shown in this figure, the target construction can be performed without imposing a weight burden on the floors of all floors.

FIG. 5 is an image of the state of FIG. 4 viewed from the top. However, due to the structure of the building, the use of beams having a relatively higher strength than the floor makes it possible to ensure safety. Is secured.

[0015]

According to the first aspect of the present invention, as compared with the conventional type shown in FIG. 6, the work of transportation, installation and release is simpler and more economical, and there is no frequent inspection and repair work even during construction. Also offers the convenience of maintaining safety.
