Description

Temporary structure for covering and its method {TEMPORARY INSTALLED STRUCTURE FOR COVERING AND CONSTRUCTION METHOD THERE OF}

The present invention relates to a temporary facility structure, and more particularly, to a temporary facility structure for covering that is temporarily installed for vehicle passage after excavation at an underground roadway construction site and the like, and a construction method thereof.

In general, temporary facilities structures are temporarily installed for vehicle or pedestrian traffic after excavation when constructing underground roads, subways, tunnels, large buildings, roads, etc. in downtown areas. As an example of a temporary facility structure, a steel roofing plate is made in the form of a flat plate having a predetermined thickness and is used to cover an excavated road surface in order to minimize the impact on traffic.

After temporarily installing piles and girders, the decking plate made of steel is installed on top of it to allow vehicle traffic. When facilities such as subway stations, underpasses, and tunnels are completed, piles, girders, and decking plates are removed. These decking plates have a flat rectangular parallelepiped shape, and dozens to hundreds of decking plates are arranged and installed to form a temporary road surface, on which vehicles pass.

The steel decking board is composed of a general steel decking board, an MMA coated steel decking board, and the like. In this way, the conventional decking board is made of steel products, but is damaged due to fatigue due to vehicle vibration and the like, and there is a risk of vehicle safety accidents. After about two years of use, it is discarded after replacement. In addition, the corrugated board made of steel has a problem in that it is expensive.

In addition, the corrugated board made of steel causes great damage to the driver of the vehicle or to nearby shopping malls or residents due to noise and vibration during vehicle passage. On the other hand, moisture from rain or snow penetrates through the gap between the steel decking board and the steel decking board connection, making the environment of the underground workshop poor and reducing work efficiency.

In addition, the corrugated plate made of steel has a problem in that it is difficult to maintain quality due to a large amount of welding, and shear failure of the welded part is frequent due to repeated fatigue during repeated driving of the vehicle. In addition, the conventional steel decking board is provided with locking holes on all sides of the upper surface of the decking board to move the decking board, and after installation, the hole is left open or blocked with a rubber stopper, resulting in inconvenience during pedestrian traffic or vehicle driving. When blocked, it protrudes above the road surface, so it has problems such as being easily damaged during repeated driving of the vehicle.

In order to solve such conventional problems, in the present invention, the material of the decking plate is composed of reinforced concrete, but it provides ease of installation in various environments, improves sealing performance, and smoothly installs and dismantles even in environments where steps occur between girders. Provides a temporary roofing structure and its construction method that can perform

The wedge grooves are inclined so that the gap between adjacent wedge grooves becomes narrower from top to bottom, constituting a wedge shape.

The reinforced concrete decking plate has a plurality of concave grooves formed in the middle of each side, mortar is poured into the joint of each reinforced concrete decking plate to ensure continuity, and the intaglio grooves are filled with mortar.

Stud bolts are coupled to the upper surface of the girder located in the wedge groove, and mortar is poured into the wedge groove.

A sealing tape is provided on the lower surface of the reinforced concrete decking plate to prevent the mortar from escaping when mortar is placed at the joint of each reinforced concrete decking board.

Lifting bolts are embedded in the upper surface of the reinforced concrete decking plate.

In the reinforced concrete decking plate, a transverse cut surface formed on one surface in the transverse direction at the corner of the reinforced concrete deck plate and inclined so that the distance to the neighboring reinforced concrete deck plate becomes closer from top to bottom, and the transverse cut surface is perpendicular to and continuous It forms a surface and is formed on one side of the longitudinal direction at the corner of the reinforced concrete decking plate, and an inclined longitudinal incision is formed so that the distance to the neighboring reinforced concrete decking plate gets closer from top to bottom, so when four reinforced concrete decking plates are connected, 4 The wedge groove is formed between the transverse and longitudinal incision surfaces of the dog.

The reinforced concrete decking plate may have a wedge groove formed on a side surface of each of the reinforced concrete decking plates facing each other.

The wedge groove may be formed with a stepped portion such that a gap between adjacent wedge grooves becomes narrower from top to bottom.

A wedge groove 210 is formed in the reinforced concrete decking plate 200. The wedge grooves 210 are formed at four corners of each of the reinforced concrete decking plates 200 facing each other between the reinforced concrete decking plates 200.

The wedge grooves 210 are formed inclined so that the gap between the adjacent wedge grooves 210 narrows from the top to the bottom, constituting a wedge shape. In this case, the wedge shape refers to a substantially inverted triangle or inverted trapezoid shape in which the cross-sectional area becomes narrower from top to bottom. That is, wedge grooves 210 are obliquely dug at four corners for the connection of the reinforced concrete decking plates 200.

In addition, a plurality of intaglio grooves 220 are recessed in the middle of each side of the reinforced concrete decking plate 200. In addition, continuity is secured by pouring mortar into the joints of each reinforced concrete decking plate 200, and mortar is filled in the concave groove 220, so that the bonding force between the reinforced concrete decking plates 200 can be increased. Reference numeral 180 shows mortar poured at the joint of the reinforced concrete decking plate. The intaglio groove 220 is recessed inward from the side wall surface of the reinforced concrete decking plate 200, and forms an inclined surface 221 so that the cross-sectional area becomes narrower toward the inside to further maximize the bonding force during mortar placement, and the reinforced concrete decking plate When disassembling the 200, the mortar can be separated more easily.

The butyl rubber 110 extends along the longitudinal direction of the girder 100 and is attached to the upper surface of the girder 100. A reinforced concrete decking plate 200 is seated on the top of the butyl rubber 110. A pair of butyl rubber 110 is provided on both sides of the girder 110 in the transverse direction.

The butyl rubber 110 is made of a material having elasticity itself, and when the reinforced concrete decking plate 200 is seated on the upper part, it seals the gap between the decking plate and the girder and also relieves the height difference between the girders 100. help That is, the butyl rubber 110 is for supporting the reinforced concrete decking plates 200 and preventing leakage of water such as joint mortar.

In particular, the butyl rubber 110 is attached to the upper surface of the girder 100 by forming an adhesive layer only on the surface facing the girder 100. In addition, the butyl rubber 110 does not have an adhesive layer on the surface facing the reinforced concrete decking board 200, making it easy to attach and detach the reinforced concrete decking board 200. That is, the butyl rubber 110 is attached to the upper surface of the girder 100 by forming an adhesive only on the lower surface of both sides in the vertical direction, and there is no adhesive on the upper surface, making it easy to install and dismantle the reinforced concrete decking plate 200.

In addition, a plurality of stud bolts 150 are installed on the upper surface of the girder 100. The stud bolt 150 may be fixed to the upper surface of the girder 100 by welding or the like, and is provided in a wedge groove for connection between the reinforced concrete decking plates 200. That is, the stud bolt 150 is coupled to the upper surface of the girder 100 located in the wedge groove 210. Mortar is poured into the wedge groove 210. Reference numeral 170 shows mortar poured into the wedge groove.

The sealing tape 190 serves to prevent the mortar from escaping when mortar is placed at the joint of each reinforced concrete decking board 200. The sealing tape 190 is attached to the bottom of the side wall surface of the reinforced concrete decking plate 200.

More specifically, a transverse cut surface 211 and a longitudinal cut surface 212 are formed at each corner of the reinforced concrete decking plate 200 . The transverse cut surface 211 is formed on one surface in the transverse direction at the corner of the reinforced concrete decking plate 200, and is inclined so that the distance to the neighboring reinforced concrete decking plate 200 becomes closer from top to bottom. The longitudinal cut surface 212 is orthogonal to the transverse cut surface 211 to form a continuous surface. The longitudinal cut surface 212 is formed on one side of the longitudinal direction at the corner of the reinforced concrete decking plate 200, and is inclined so that the distance to the neighboring reinforced concrete decking plate 200 becomes closer from top to bottom.

As shown in Figure 12, the lower length (a) of the transverse incision surface 211 is formed longer than the upper length (b), the lower length (c) of the longitudinal incision surface 212 is the upper length (d) formed longer. In this way, when the four reinforced concrete decking plates 200 are connected, the wedge grooves 210 are formed between the four transverse cut surfaces 211 and the longitudinal cut surfaces 212. Through this configuration, the plurality of reinforced concrete decking plates 200 can be continuously connected to each other in the transverse and longitudinal directions, and the height difference between the girders 100 can be efficiently overcome depending on the installation environment.

Thereafter, a step of installing the reinforced concrete decking plate 200 on the adhesive-free upper surface of the butyl rubber 110 attached to the girder 100 using the lifting bolts 230 installed on the upper surface of the reinforced concrete decking plate 200 is performed. . Subsequently, mortar is poured into the stud bolts 150 on the girder 100 and the wedge groove 210 of the reinforced concrete decking plate 200 to integrally combine the girder 100 and the reinforced concrete decking plate 200. do.

Thereafter, after attaching the sealing tape 190 to the lower surface of the reinforced concrete decking plate 200, mortar is poured into the joint of the reinforced concrete decking plates 200 formed with the intaglio grooves 220 to integrate the reinforced concrete decking plates 200 with each other perform the bonding step. In this way, a series of installation processes of the temporary facility structure are completed.

In addition, the dismantling method of the temporary facility structure according to an embodiment of the present invention is a method of dismantling the reinforced concrete decking plate 200 after use, first, removing the wedge groove 210 of the reinforced concrete decking plate 200 and the mortar at the joint perform the steps Thereafter, a step of cutting and removing the stud bolt 150 coupled to the upper surface of the girder 100 is performed.

After that, a step of lifting and dismantling the reinforced concrete decking plate 200 from the girder 100 is performed using the lifting bolts 230 installed on the upper surface of the reinforced concrete decking plate 200. After that, the girder 100 is removed from the site After performing the step of dismantling and moving to the yard, removing the butyl rubber 110 attached to the upper surface of the girder 100 and cleaning and storing the girder 100 and the reinforced concrete decking plate 200 for reuse carry out

On the other hand, Figure 14 is a perspective view showing a temporary facility structure according to another embodiment of the present invention. Referring further to FIG. 14, wedge grooves 210 are formed on the side surfaces of each reinforced concrete decking plate 200 facing each other. A plurality of stud bolts 150 are installed on the upper surface of the girder 100. The stud bolt 150 is coupled to the upper surface of the girder 100 located in the wedge groove 210. Mortar is poured into the wedge groove 210.

Even in this case, the stud bolt 150 is coupled to the upper surface of the girder 100 located in the wedge groove 210. Mortar is poured into all the wedge grooves 210.

On the other hand, further referring to FIG. 16, the wedge groove 210 may be formed with a stepped portion 209 such that a gap between adjacent wedge grooves becomes narrower from top to bottom. The stepped portion 209 can further maximize the bonding force between the reinforced concrete decking plates 200 when placing the mortar, and makes it easier to separate the mortar when the reinforced concrete decking plates 200 are dismantled.

Conventional steel roofing boards are not durable and cannot be used for more than two years after installation. After two years have elapsed since installation, the steel roofing plate must be dismantled and scrap metal disposed of. On the other hand, the reinforced concrete decking board of the present invention can be reused by moving to another site after being dismantled even after using it for 5 years or more. The reason for reusability is that the self-durability of the reinforced concrete decking board is improved and the combined structure of the reinforced concrete decking board consisting of a plurality of pieces with optimized wedge grooves and intaglio groove shapes is realized. The plurality of reinforced concrete decking plates are not only easy to install, but also can be reused efficiently because the shape of the wedge groove and the intaglio groove can be maintained without damage during disassembly.

Through this configuration, the present invention can eventually drastically reduce carbon emissions and provide an eco-friendly product that is economically superior to steel decking. In addition, since the surface on which the vehicle goes underground is not steel, but concrete, compared to the conventional steel decking plate, it is possible to minimize damage by dramatically reducing vibration and noise. In addition, the conventional steel corrugated board requires a separate MMA coating to prevent slipping of vehicles, etc., resulting in additional costs. On the other hand, in the present invention, since the upper surface of the decking board is concrete, it has high sliding resistance, prevents slipping accidents, has excellent safety, and is economical because it does not require additional coating work.

In addition, the conventional steel decking board has gaps between the decking boards, and when it rains or snows, water flows down through the gap, making the working environment in the underground space poor. On the other hand, since the present invention fills the joint of the reinforced concrete deck plate with mortar, it is possible to prevent water from flowing down due to rain or snow in the underground space, making the working environment remarkably comfortable. In addition, since the bending strength and rigidity of the reinforced concrete decking plate itself are improved, it can effectively withstand the bending moment and impact caused by the load of vehicles passing through it.

So far, the temporary facility structure and its construction method according to the present invention have been described with reference to the embodiment shown in the drawings, but this is only exemplary, and anyone skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. .
