Description

  The present invention relates to a method for constructing piles and beams in a basement that constitutes a building.

  Conventionally, regarding the structure of piles and beams in this type of basement, as shown in FIG. 1, first, a pile 2 of a building is first driven, and then a stake 1 is provided on the outer periphery thereof, and the ground surface inside the stake is provided. Is excavated to the bottom of the basement, crushed stone 4 is laid on the basement of the basement, then spot pressure is applied and ready-mixed concrete is laid. After arranging the bars on the wall 7, the upper beam 8, and the ceiling portion 9, a temporary frame is formed, and the concrete of the basement is constructed by driving ready-mixed concrete into the temporary frame.

  However, in such a conventional building structure, since the upper beam 8 and the lower beam 3 are constructed at the upper and lower parts of the basement, the construction period is long and a large amount of cost is required.

  In addition, since the upper beam 8 of the foundation projects into the basement, a feeling of pressure is generated in the indoor space of the basement, and a dead space is generated in the arrangement of stairs and the like.

  In addition, after constructing the basement lower beam 3 and the pressure plate 6 with concrete, the basement wall 7, the upper beam 8, and the ceiling 9 are constructed with concrete in a certain number of days. There was a problem that groundwater entered the basement from the joint surface between the two.

Therefore, when the basement is constructed, the present invention reviews the conventional construction method of the pile 2, the upper beam 8, and the lower beam 3, and eliminates the protrusion of the upper beam 8 into the basement, so that there is no feeling of pressure. In addition to creating an indoor space, the reinforced concrete temporary frame for constructing the floor, wall, upper beam surface, and ceiling surface is integrally configured, and the basement structure is integrated into a single structure with no concrete joints. It is an object to provide a method for constructing basement piles and beams that can prevent water leakage, shorten the construction period, and significantly reduce costs.

In order to achieve such a subject, the invention according to claim 1 is a construction method of a pile and a beam constituting a building and its basement, and when the pile is driven into the ground, the upper part of the pile is used as an upper beam reinforcement of the basement. In order to dig into the ground to the height to be incorporated, and to dig the outer periphery of the driven pile to the lower part of the upper beam of the basement, a simple mountain stop using a keystone plate is made to the depth of the upper beam reinforcement. Then, it is driven deep into the ground, and then the surface inside the simple mountain excavation is excavated to the top of the pile, and further, a lightweight mountain steel using a deck plate on the inner perimeter of the pile can be built into the basement concrete frame. After digging into the ground, excavating the ground inside the lightweight steel retaining steel to the bottom of the basement, laying crushed stones at the bottom of the basement, and then throwing away the concrete with spot pressure, and then the walls of the basement When arranging the reinforcing bars that make up the floor and the beam, the upper beam reinforcing bar to form the upper beam of the basement is configured so that the interior surface of the upper beam and the interior surface of the wall are in the same plane with no step. In addition, in order to ensure the strength of the upper beam of the basement, the cross-sectional shape of the upper beam of the basement is configured to be narrow and vertically long, the upper part of the pile is incorporated inside the upper beam, and the upper part of the pile and the upper beam are welded together. The pile and the upper beam are built in one piece, and the column 0 of the building is embedded in the upper beam reinforcement, and the lower part of the column 0 is fixed slightly above the lower surface of the upper beam reinforcement by welding with the upper beam reinforcement. It is characterized by the fact that the bottom beam of the basement is eliminated by supporting the building load with a pile incorporated in the top beam of the basement.

  According to the invention of claim 1, the pile is driven to the lower part where the upper beam reinforcing bar of the basement is constructed, and the upper beam is constructed at the upper part of the pile so that the pile is incorporated into the upper beam reinforcing bar, By eliminating the lower beam of the basement, an expensive base pack as in the prior art becomes unnecessary, and by eliminating the lower beam, the construction period can be shortened and the cost can be greatly reduced.
