Abstract

PURPOSE: A method for piping by a pit structure inside a vertical shaft of a building is provided to safely work during piping operation, to reduce danger due to various disasters, to promptly complete a working process, to solve problems by the present Fire Services Acts, and to reduce construction costs. CONSTITUTION: A method for piping by a pit structure inside a vertical shaft of the building includes the steps of making a pit structure as the exclusive use of a vertical piping pit, manufacturing the bottom of a patterned steel plate(1), using steel angles(2) on the bottom and four edges to reinforce the steel plate bottom, manufacturing the pit structure in which one area is the total height of four stories, and welding main pipes and branch pipes except connected inlets of the branch pipes.

Description

BUILDING VERTICAL SHAFT IN PIT STRUCTURE PIPING SYSTEM}

When installing the main pipe in the building pit, several pipes should be installed according to the purpose of the building.In the current piping method, the main pipe is installed after the steel angle is installed in the pit to fix the main pipe in each floor. After cutting the pipes to the height of each floor and bringing each pipe into the pit, fixing each pipe with a u-bolt at a fixed angle, welding each pipe by one floor to complete the work. In order to block the spread of the fire to other floors as the standing feet play the role of the year, after completion of the standing main pipe work in the pit, the floor of each layer of the pipe pit must be blocked with a concrete, etc. There are many difficulties in the process of blocking the floor, and now the piping work is done before the pit floor is blocked. Workers should work in the danger of disaster, and when the building is repaired, the building will be shocked by the vibration caused by the removal of each floor in the pit, and the noise will be damaged around the building. The process is late and construction costs are high.

An object of the present invention is to reduce the risk of a disaster, while working in the safety of the plumbing work in the vertical pipe fitting, the problem according to the current fire method must be solved, and the work process is also completed quickly and the cost of construction is reduced.

In order to achieve the above object, in order to speed up the risks of fire accidents, fire fighting methods, and plumbing work, the worker first cuts the patterned steel plate slightly smaller than the building pit as shown in FIG. In order to facilitate the branch pipe work on each floor, each main pipe location shall be selected and drilled into the patterned steel plate for use as the pit floor, and the main pipe location will be determined. As the cut iron plate is punched like this, when the pit structure is completed, when viewed vertically from the main pipe position, the hole should be drilled in the iron plate so that the hole position of the pipe is in the same line.

In order to reinforce the pit bottom iron pipe cut in FIG. 3, a steel angle (Angle) is made by welding a square, and then a perforated cut pattern iron plate is welded to a square angle plate to make a pit bottom plate. The pit bottom plate manufactured as shown in Fig. 3 is the height of the floor of the building, and the four floors of the floor board are welded to each other by the height of the floor of the building to fix the four floor boards to the side, and to fix the pit bottom plate. As shown in Fig. 4, a pit structure having four layers in one zone is formed. When the pit bottom structure is completed as shown in Fig. 4, the pit structure is laid sideways and the piping work is performed. The main pipe is placed in the hole position where the main pipe of each layer is drilled, and the main pipe welding is performed on the pit bottom plate from the lower floor direction. . When welding each main pipe, the direction of the branch connection and the height of the connection location of each floor shall be determined from the floor of the building. When the location and height of the tee of each branch pipe connection part of the main pipe are determined, the pipe is welded and the next main pipe is connected to complete one pit structure. The pit structure has four floor heights in one zone, and completes the welding except for the main pipe welding and branch pipe connection entrance from the outside. The pit structure completed in one area should be installed from the bottom floor, and the tower crane on site should be used, and the roof structure should be carried into the vertical pipe feet from the rooftop floor. When installing the pit structure, the bracket is made as shown in Fig. 6 in the bottom pit of the first floor, and the pit structure is installed after fixing the bracket with an anchor to the concrete wall in the pit. After the first installation of the pit structure, four brackets are firmly attached to the bottom iron plate of each layer of the pit structure where the bracket is installed. After installation of the first pit structure, when connecting the next pit structure, the pipework is easily cut at 30 cm from the bottom of the upper part of the first pit structure, as shown in Fig. 7, and the bottom of the next connection pit structure is 30 cm. Cut the pipe short, so that the work can be done at the bottom of the connecting feet when welding. When the first pit structure and the second pit structure are connected as shown in FIG.-7, the bottom plate is not overlapped with the connection joint, and only the bottom angle is installed in the upper pit structure with the bottom plate removed to manufacture the pit structure. Since the bottom plate is removed from the lower connection portion of the upper pit structure, when the upper and lower pit structures are connected to each other, the upper main pipe is fluid and there is an effect of facilitating pipe joining. The length of the support angle on the upper structure is 50mm smaller as shown in Fig.-7 so that the upper and lower pit structures do not directly touch when joining, and only the pipes touch each other when welding the main pipe.

The pit structure of the present invention, in the building pit, the pipe work is completed in the pit structure having one area of four floors from the outside without the piping work as before, since the piping work is carried out, only the pipe connection work of each floor In addition, there is no danger for workers because there is a bottom in the pit structure, and after the piping work due to the fire method, the floor plate for the main pipe support protects the floors and layers of the current fire method during the construction of the pit structure so that the pit structure is not blocked. When the renovation works, only the pit structure separated by the zone is to be taken out and lifted up, and when it is newly established, the pipe is connected to the pit structure and the pit structure with the main pipe work and the pit bottom closed four layers at a time. The process is also fast and it is possible to finish insulation of the pipe when the pit structure is completed from the outside.
