Abstract

The present invention is characterized in that waterproof sheets prepared by standardizing waterproof coating layers formed on a top surface of a roof of a building in a predetermined size are spaced apart from each other by a predetermined distance and are adhered adjacent to each other, The present invention relates to a building roof waterproof composite structure and a construction method thereof, which can be easily installed while shortening the construction time while effectively watertighting between waterproof sheets adhered to each other by embedding in a 'T' shape as a coating layer.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-

More particularly, the present invention relates to a waterproof structure of a building roof and a construction method thereof, and more particularly, to a roof waterproof structure of a building, And the waterproof sheets are adhered to each other, and then the waterproof sheets adhered to each other are embedded in the sealing coat layer in a 'T' shape to effectively waterproof the adjacent waterproof sheets, thereby simplifying the construction and shortening the construction time And a method of constructing the waterproof structure.

Generally, waterproofing work is carried out on the roof of the building to prevent water leakage due to rainfall or the like. The waterproofing works include mortar liquid waterproofing, water-soluble or water-proofing of water resistance, asphalt waterproofing and waterproofing sheets, and the waterproofing sheet is widely used for waterproofing due to its relatively simple construction and shortening of construction time.

These waterproof sheets are made of synthetic rubber, synthetic resin or rubberized asphalt which have excellent storability and have a certain width and length (usually 1 ~ 1.2m, length 15m) in factory in order to facilitate construction and handling in the field. Because they are wrapped on a roll, they are installed at regular intervals on the top of the roof while winding the waterproof sheet during installation.

In the waterproofing method using the waterproof sheet, since a plurality of standardized sheets are used, a connection portion between the sheets is inevitably generated. Such a connection portion is the most vulnerable part in the waterproof performance of the waterproof sheet, In this case, leakage occurs through this part, leading to waterproof defects.

In order to solve such a problem, in Korean Patent No. 10-337618 (registered on Apr. 22, 2002) and Korean Patent No. 10-733502 (Registered on June 22, 2007) However, the method using the lap splice method has a problem that the waterproof performance depends on the skill of the operator.

Korean Utility Model No. 10-2006-032188 (Publication Date: Apr. 14, 2006), Korean Utility Model No. 20-2008-004955 (Publication Date: October 28, 2008) A method has been proposed in which an adhesive is applied to the lower part of a waterproof sheet and the waterproof sheet is installed on the surface of the waterproof sheet so that a space is not formed between the waterproof sheet and the surface of the waterproof sheet. Since it is necessary to install the sheet sequentially when installing the sheet, it takes a lot of time to construct the sheet, and since the overlapping portion occurs between the waterproof sheets at the time of installation, the efficiency is lowered due to the separate sealing and reinforcement work.

As described above, in the construction method using the combined-joint fitting according to the related art, two or three or more waterproof sheets are overlapped to each other, and a dead space is generated inside the overlapping joint to secure watertightness There was a difficult problem. In addition, when the waterproof sheet is adhered, the waterproof sheet melted by heat or a solvent is cured and the waterproof sheet shrinkage force (stress) is generated, which may cause long-term durability problems.

In particular, when the rooftop surface moves due to climate and seasonal changes, the concrete structure may behave in either direction, but it may behave differently in right and left directions. At this time, The waterproof layer formed on the top of the roof surface was not able to conform to the roughening force of the roof surface, and the joint between the waterproof sheets was broken first, which caused defects.
