Description

PC wall for basement of side wall with hollow groove to prevent condensation

The present invention is formed to improve the condensation, leakage, cracking and workability degradation of the outer wall generated from the existing RC method using the formwork in the construction of the outer wall of the building, which is to form the wall construction of the PC, Inside the PC Underground Wall (PC Wall), a number of hollow condensation prevention grooves are provided, and the connection joints with neighboring PC Underground Walls are formed to fill the concave-convex, groove-coupled coupling parts and leak-proof water stops. The workability and productivity (air shortening) according to the construction of the outer wall is improved, while condensation, leakage and cracks are prevented. .

In general, as shown in Figure 1, the underground building is generally made after the excavation (civil engineering) and the foundation (floor), and then using the formwork on the construction of the outer wall with the site concrete by RC method slab on the upper end of the outer wall It is formed by raising (half PC slab).

However, in the exterior wall construction by the RC method, after the formwork is installed to erect the wall, the concrete wall must be cured by placing concrete in the formwork so that the following process can proceed, so that the formwork must be installed and removed every day. In addition, there is a disadvantage in that the construction period is long according to this, as well as the construction wastes used when constructing the site-casting concrete was generated, causing the environment pollution.

In addition, condensation occurs on the outer circumferential surface of the conventional outer wall, which is constructed by the site concrete, and condensation occurs when the water flows to the interior outer wall in severe cases, while cracks occur on the outer wall that is not sufficiently dried. There is a problem that leads to leakage.

The present invention is to solve the above-mentioned problems, the technical gist of the construction is to improve the condensation, leakage, cracking and workability degradation of the outer wall generated from the existing RC method using the formwork in the construction of the outer wall of the building It is to be formed, the wall construction to form a PC, but the inside of the PC underground outer wall (PC wall) to provide a plurality of hollow grooves for preventing condensation, the connection joint with the neighboring PC underground outer wall of the concave-convex, groove groove type Condensation is characterized in that the workability and productivity (shortening of air) are improved due to the construction of the coupling part and the water repellent material for preventing leakage, while condensation and leakage and cracks are prevented to improve the workability. It is an object of the present invention to provide a PC wall for an underground outer wall having a hollow groove for prevention.

In order to achieve the above object, the present invention includes a plurality of hollow grooves (100) formed to penetrate in the vertical direction inside the PC underground outer wall (P) to prevent condensation on the indoor side; A joint part 200 formed in a left and right direction of the PC underground outer wall P and formed to be coupled to a neighboring PC underground outer wall P; An index member 300 filled in the joint part or introduced to both ends in a width direction to block water from flowing from the outside to the inside; .

At this time, the hollow groove 100 is formed with a diameter of 30 ~ 150mm, it is preferable that 3 to 20 dogs are arranged at equal intervals in the longitudinal left and right sides of the PC underground outer wall.

Meanwhile, the joint 200 has grooves 210 formed at both ends of the PC underground outer walls facing each other so as to connect and couple neighboring PC underground outer walls P to the left and right, and at the center of the groove 210. A plurality of 'U' shaped reinforcement reinforcement reinforcement 220 branched to the outside is formed so as to overlap the upper and lower neighboring reinforcement (220a) based on the support reinforcement 10, the width except the groove At both ends of the direction, it is preferable that the index member 300 is formed so as to be poured by the site concrete (C).

Thus, as another embodiment, the joint 200 forms grooves 210 inwardly at one end of the PC underground outer walls facing each other to connect and couple neighboring PC underground outer walls P to the left and right, and the other end. It is also possible to form a fitting protrusion 230 corresponding to the groove 210, the field concrete (C) is poured after the index material is embedded in both ends of the width direction except the groove and the fitting protrusion.

In addition, the joint 200 as another embodiment, the grooves 210 are formed inwardly at both ends of the PC underground outer wall facing each other to connect and couple the neighboring PC underground outer wall (P) from side to side, the groove At the center of the 210, a plurality of 'U' shaped reinforcing bars 220 branched outward are arranged to overlap with the reinforcing bars 220a adjacent to each other based on the supporting bars 10. , The index member 300 is embedded at one end of the width direction except for the groove, the other end is formed to be formed by the field concrete (C) after the expansion opening is formed, blocked by the form 500 It is also possible.

As described above, the present invention is to form the construction of the basement outer wall of the building in the PC, the interior of the PC underground outer wall is provided with a plurality of hollow grooves for preventing condensation, and the joint joint with the neighboring PC underground outer wall, irregularities, groove coupling type Formed to fill the coupling portion and the water leakage preventing material to improve the workability and productivity (shortening the air) according to the construction of the basement outer wall, while condensation and leakage and cracks are prevented, the construction properties are excellently improved.
