Description

Building leakage prevention structure and construction method thereof

The invention relates to a leakage prevention structure of a building and a construction method thereof, in particular to a contraction gap portion which can be applied between a continuous wall or an outer wall of a building and a floor panel, so as to prevent external water from leaking into the building interior. Leak-proof structure of space and its construction method.

The continuous wall structure of the conventional building is shown in Fig. 1. First, a continuous wall 100 is built around the building base. The depth of the continuous wall 100 is determined according to the number of floors and the construction drawing of the basement. After the construction of the 100 is completed, the full excavation can be performed, and the earth in the continuous wall 100 is completely excavated, and then the uppermost concrete upper plate 200 is applied at the upper end of the continuous wall 100, and the innermost layer in the continuous wall 100 is applied most. The lower concrete lower deck 300 is applied as a concrete slab 400 between the concrete upper deck 200 and the concrete lower deck 300, thus constructing a plurality of basement spaces. However, the continuous wall 100 is pre-applied to the solidified concrete wall, so that when the earth is completely excavated and the upper plate 200, the lower plate 300 and the floor plate 400 are applied, the upper plate 200, the lower plate 300 and the floor plate 400 are In the secondary grouting operation, since the concrete shrinks when solidified, the structure cannot be completely adhered to the continuous wall 100, and a shrinkage gap of water leakage often occurs from the joined portion.

As shown in FIG. 1, it occurs in the water leakage between the continuous wall 100 and the upper plate 200, and is usually watered by the gap A1 between the outer wall 500 and the upper plate 200 outside the continuous wall 100, and then from the top of the continuous wall 100. A gap A2 between the face and the upper plate 200 leaks into the indoor space. Further, as shown in Fig. 1, the water seepage (groundwater) occurring between the continuous wall 100 and the lower deck 300 penetrates into the indoor space from the gap A3 between the continuous wall 100 and the lower deck 300. Due to the above problems of water leakage and groundwater infiltration, many troubles in construction work are caused, and the construction quality and progress are directly affected. Therefore, the related construction industry does not want to overcome the problems of water leakage and water seepage.

The main object of the present invention is to provide a leakage preventing structure of a building and a construction method thereof, which can be applied to a structure of a concrete vertical wall and a concrete upper slab of a building, and an upright wall of an outer guiding wall on a concrete vertical wall. A water strip and an expansion water stop are fixed on the surface, and then a concrete upper layer is connected to the concrete vertical wall, and the water intercepting strip and the expanded water stopping strip are coated through the concrete upper layer to make the water intercepting strip and the expansion water stop. The strip blocks the leaking water in the area where the water leaks easily. When the external groundwater leaks from the gap between the concrete vertical wall and the concrete upper deck, the intercepting strip and the expanded water stop strip intercept the water, so that the water is guided to other places. In order to prevent the groundwater from leaking into the indoor space from the gap between the concrete vertical wall and the upper deck.

A secondary object of the present invention is to provide a leakage preventing structure of a building and a construction method thereof, which can be applied to a structure of a concrete vertical wall and a concrete lower deck in a basement, which is fixed below a vertical wall of a concrete vertical wall. A water strip and an expansion water stop strip are applied as a concrete lower deck to the upright wall of the concrete vertical wall, and the water cut strip and the expanded water stop strip are covered by the concrete lower deck to make the water intercepting strip and the expansion stop The water strip blocks the water that is easy to see up. When the groundwater under the concrete lower deck leaks from the gap between the concrete vertical wall and the concrete lower deck, water intercepts through the water intercepting strip and the expansion water stop to guide the water. It is discharged to other locations to prevent the groundwater from leaking into the indoor space from the gap between the concrete vertical wall and the lower deck.
