Description
BACKGROUND OF THE
Generally, a gang form is a work platform for constructing an outer wall of a concrete structure having the same cross-sectional shape as an apartment or a building, such as an apartment or a building. The gang form is constructed of an outer wall refuse house, a mold installation, dismantling work, ) It refers to a large formwork which is made by integrally making a cage for work scaffolding.
The cage is a part of the gang form which is composed of a work footrest, a safety guardrail, etc., which is necessary for safely performing operations such as formwork dismantling work, dismantling work, follow-up work, and decorating .
The cage is divided into an upper cage and a lower cage, and the upper cage refers to an upper two-stage work foot part used for forming and disassembling the four-step work foot of the gang-shaped cage. Further, the lower cage refers to a lower two-stage work foot component used for plastering and decorating work.
Such gauze is formed by attaching a plate-shaped forming foam to the side of the cage composed of one or two stages and installing and disassembling the formed foam in a state where the worker can climb on the cage side and the outer wall of each layer of the concrete structure can be constructed, And is capable of proceeding with subsequent work, such as plastering, leeches.
The gauze is sequentially moved by a tower crane so as to enable the construction of the outer wall of the upper layer after the construction of the outer wall of the lower layer of the concrete structure, so as to correspond to the outer wall surface of each layer.
As shown in FIG. 1, the conventional gang-foam is constructed of a
In addition, the work platform safety footrest constructed on the gang form is manufactured by welding the wire net required according to the width and length of the gang form to a pre-fabricated square pipe, and then forming a safety foot by fitting the square pipe.
However, since the conventional gauze is shaped to have a certain width and length, it can be suitably used for a building having a rectangular cross section. However, as shown in Fig. 2, There is a problem that a fall occurs due to carelessness of the operator due to such an interval.
In order to solve the above problem, a separate safety net is installed in the gap between the gangs in the conventional gang-bang to shorten the fall height of the worker, thereby minimizing the worker's injury.
However, even in this case, there is a problem that the worker's fall is not blocked from the source through the gaps between the gang forms, merely by installing a safety net between the gangs to minimize the injury of the worker who falls down.
In addition, there is a problem in that the competitiveness of the product is lowered due to the addition of the installation cost, in which a separate safety net, which is not related to the operation, is added.
Further, in addition to the gang form, a safety net should be additionally provided at intervals between the gangs. In this case, there is a risk of a safety accident such as falling due to carelessness of the operator.
It is an object of the present invention to provide a cage which is formed on the outer periphery of a forming foam and a molding foam and which is capable of forming and exteriorsing an outer wall, And a variable cage which is formed at one end or both ends of the fixed cage and whose fixed interval is adjusted in the fixed cage. Thus, the interval between adjacent cages installed on the outer periphery of the building is adjusted according to the user's request, And to provide a variable gang that can be installed in accordance with the external appearance of a building so as to improve the safety of installing a secure cage without installation.
In order to accomplish the above object, the present invention provides a cushioning structure for a cushioning cushion, comprising a molded foam and an outer cage installed outside the cushion to form an outer wall and an outer wall formed in a downward direction Wherein the cage comprises a fixed cage having a constant width; A variable cage configured to be spaced apart at a predetermined distance from one end or both ends of the fixed cage so as to adjust the gap between neighboring cages according to a user's request; And a gap adjusting unit formed between the fixed cage and the variable cage to provide a feed force so that the interval of the variable cage can be adjusted based on the fixed cage.
In the present invention, the fixed cage includes a plurality of first vertical bars which are vertically erected at regular intervals, at least one first horizontal bar fixed horizontally at a predetermined interval along the longitudinal direction of the first vertical bars, And a fixed footrest fixed to a lower end of the first vertical bar to support a worker so as to be able to pass therethrough; The variable cage includes at least one second vertical bar vertically erected, a horizontal bar fixed at a predetermined interval along the longitudinal direction of the second vertical bar, and adapted to be inserted into the first horizontal bar at least And a variable footrest fixed to the lower end of the second vertical bar to support the worker so as to be able to pass therethrough.
In the present invention, the gap adjusting portion may include a first housing fixed to one side of the fixed cage and having a spiral formed therein; A second housing having a same line as the first housing and fixed to one side of the variable cage; And a screw shaft coupled to the first housing so as to be moved forward or backward along the rotational direction and coupled to the second housing at the other end so as to move forward or backward without interfering with rotation .
In the present invention, it is preferable that a first stopper is provided at one side of the screw shaft so that the first housing is closely contacted when the screw shaft is advanced and forwarded by the rotational direction so that the advancing length is limited.
According to the present invention, it is preferable that the one end of the screw shaft further includes a head for facilitating the turning operation of the screw shaft through the tool.
According to the present invention, there is provided a cage comprising a molded foam and a cage formed on an outer periphery of the molded foam to form an outer wall and to externally work, wherein the cage is formed on one end or both ends of the fixed cage, And the variable cage having a fixed interval in the fixed cage. Thus, the interval between adjacent cages installed on the outer periphery of the building is adjusted according to the demand of the user, so that a safe cage can be installed without installing a separate safety net .
