The present invention relates to a temporary lamp for earthwork using a building structure, and more specifically, by installing a temporary lamp for underground construction using a building structure, it is possible to carry out soil and rock removal in a short period of time, and thus breakthrough air It relates to a temporary lamp for earthworks using a building structure that can implement a short axis.

In general, earthwork is the work of excavating and completing the space up to the ground surface necessary for constructing the foundation or basement in constructing a building structure, and then refilling the ground surface.

Usually, in order to construct a building structure, continuous wall work, RCD work, earthwork, etc. should be carried out.

Here, earthwork is a construction that is the first to be started in the early stages of construction, along with temporary construction, and it is a work to dig out and fill up the soil for installing the foundation and underground structures and stabilize the ground state.

Digging methods for earthwork are largely open cut, island method, trench cut method, top-down method.

Particularly, in large cities, the construction of buildings is required even in areas with poor ground conditions such as landfills and riversides where high-rise buildings are constructed in poor conditions, and the safety of underground construction is required. As the site boundary is planned so close together, there is no space for the work vehicle to stop during construction, and the construction is required to proceed with the situation that there is no choice but to damage the surrounding area.

Under these conditions, the construction may not be possible with the conventional construction methods. Therefore, it is necessary to adopt a comprehensive underground construction method including concrete construction and finishing construction in excavation construction.

Therefore, the top-down method (reverse method) is constructed without breaking the outer walls and underground columns first, and after completing the ground floor structure, excavating the ground underneath and repeating the construction of the underground floor structure to the lower floor. As a method of finishing the concrete by constructing the foundation beam at the end, it is possible to use the first floor beam and the floor structure as the working floor by adopting the reverse reversal method. In addition, it is possible to use excavation and concrete construction from the upper floor to the lower floor while using the main structure of the building as the earth retainer. Therefore, the earth walls are high in safety and the air can be shortened by combining ground and underground construction. It is a trend that is widely applied to earthwork for building construction.

Soils and rocks usually generated as the earthwork proceeds are taken out by trucks, and the earthwork is carried out by digging out the remaining parts while securing passages for passage of such trucks, for example, lamp structures. Doing.

That is, the truck descends to the basement floor where the dig is being carried, and the soil is carried out to the outside, and the truck moves through the lamp structure that is left without digging.

After completion of the excavation for a certain area, the ramp structure is finally additionally excavated, and the soil or rock coming out at this time cannot be transported by truck, and thus it is taken out to the outside by sending it out through the opening to the crane or the like from the ground.

However, the excavation of the ramp structure used as a truck passage and the excavation of the soil and rock at this time is a major cause of the increase of the overall construction period, which takes considerable work time and requires a lot of labor. .

In particular, in the case of ramp structures, the amount of soil and rock generated at this time is considerable because the size and volume of the lower support portion must be wider than the upper passage portion of the truck for safe movement of the truck. After all, most of the construction period required for earthworks has a problem in removing the lamp structure.

In order to solve the problem of earthwork due to the existing lamp structure, temporary lamps consisting of separate frame structures are applied at some construction site construction sites. In terms of labor force and working period, efficiency is inferior, and when applying a temporary lamp of such a frame structure, it is difficult to secure a copper wire considering the construction process, and there is a difficulty in layout excluding interference with surrounding structures. There are disadvantages in terms of sex.

Therefore, the present invention has been made in view of the above, by implementing a new type of temporary lamp system for installing a temporary lamp for the passage of trucks using the pillars of the building structure, to carry out soil and rock to work directly up It can be implemented in a short period of time, and thus the purpose is to provide a temporary lamp for earthwork using a building structure that can significantly shorten the construction period.

The present invention for achieving the above object is characterized in that the steel frame used as a pillar of the building structure as a support made of a structure in which the installation of a temporary lamp in the form of a frame structure.

In addition, the hypothesis lamp includes a frame body of a rectangular frame structure is supported while being arranged in a form spanning between the steel frame of both sides arranged side by side or at a predetermined interval, and a perforated plate covered on the upper portion of the frame body It is characterized in that the configuration.

In addition, the frame body of the temporary lamp is characterized in that it comprises a plurality of reinforcing members arranged at regular intervals along the longitudinal direction while crossing the width direction.

In addition, a plurality of horizontal members which are installed in the upper part of the frame body of the temporary lamp and arranged at regular intervals along the longitudinal direction at the same time across the width direction of the main body, and cross the front and rear two horizontal members on the plane and at the same time on the side It characterized in that it further comprises an X-brace consisting of a plurality of braces fixedly installed in the cross shape.

In addition, the hypothesis lamp is characterized in that the ramp is lowered inclined along the steel frame of both sides and at the same time the lower end portion of the lamp is constructed in a structure that is supported by the support frame.

In addition, the hypothesis lamp is characterized in that it comprises a straight section for straight running and a bending section for changing the direction.

In addition, the hypothesis lamp is characterized in that it comprises a section of the inclined surface and a section of the flat surface.

In general, H-pillars are installed in a predetermined grid and arranged within a predetermined area. Therefore, when a soil discharge opening (opening part) is determined for access to a truck, a predetermined path is secured from this place. Using the H-pillars arranged in this way, a temporary lamp in the form of a frame structure can be installed.

Occasionally, even when the H-pillars are arranged in an irregular shape in a planar layout, the temporary lamps may be installed by using H-pillars on both sides at a suitable distance.

These hypothetical lamps are formed in the form of a long passageway having a width that can be passed by about two trucks, and the length of the lamps is extended in such a way that they are continuously attached to the work process to dig out the basement. can do.

That is, since the length of the temporary lamp is not fixed but can be continuously extended, the present invention will be described based on the length of the temporary lamp of the form that is continuously installed in several floor units for convenience of description.

In addition, the temporary lamp has a structure that is inclined down between the steel-columns of both sides because the earth and sand from the basement to be carried out, the lower section of the lamp by the support frame made of a suitable standard according to the conditions of the site It is treated as a supported structure.

In addition, the path of the temporary lamp is preferably in the form of a straight section in the inclined state or a horizontal state to secure the copper wire considering the building process, but the direction through the section of the flat surface rather than a straight line according to the conditions of the site layout. It may be in the form of some bends, for example for conversion
