Problems solved by technology

However, due to the following reasons, the basement deformation joints often cause leakage after construction: 1. The quality of the rubber waterstop is poor, and it ruptures under the action of water pressure; 2. The construction process is rough, and the contact surface between the rubber waterstop and the concrete seeps; 3. .The rubber waterstop is not closed and leaks at the joint; 4. After long-term use, the waterstop is aging

Embodiment Construction

[0025] The specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications without creative contribution to the present embodiment as required after reading this specification, but as long as the claims of the present invention are protected by patent law.

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] In order not to affect the use function of the basement floor, the present invention utilizes the 100mm space between the basement floor structure layer and the finished surface of the building to install the device. For the underground roof and side walls, because there is enough space, only the building surface needs to be chiseled out. layer. The waterproof device of the present invention is fixed on the basement floor and wall on both sides of the deformation joint by post-anchor planting ...

Abstract

The invention discloses a rear replaceable type waterproof device for a deformation joint of a basement and an installation method thereof. The rear replaceable type waterproof device comprises angle steels, wherein the angle steels are arranged at the two sides of the deformation joint of the basement; drilling holes at the two sides of the deformation joint are provided with screw rods; the contact surfaces of the angle steels and the deformation joint are provided with bonding layers; rubber water-stopping belts are arranged above the angle steels at the two sides and at the inner sides opposite to the screw rods; and pressing devices are arranged above the rubber water-stopping belts and are fastened by nuts. The rear replaceable type waterproof device disclosed by the invention has the advantages that the waterproof device is arranged on the backwater surface of the completed basement without being pre-buried in advance, namely the rear type, so that the difficult problem that members can not be pre-buried at the backwater surface for water leakage and water prevention of the deformation joint of the basement is solved, the device is replaceable and is convenient for maintenance in the future.

Description

technical field [0001] The invention relates to a rear replaceable basement deformation joint waterproof device and an installation method thereof, belonging to the field of architectural design and waterproof construction. Background technique [0002] At present, the underground space is widely used. The plane shape of the basement is more and more complex and irregular, and the area of ​​the basement is also increasing. How to solve the large-area basement concrete shrinkage deformation and thermal expansion and contraction deformation caused by temperature changes during use , and eliminating the temperature stress that is unfavorable to the structure caused by deformation has become a difficult problem in the design and construction of the basement. Currently, setting deformation joints is one of the common and effective methods to solve the above problems. The usual method of deformation joints is: in the side walls of the basement, The middle part of the top plate and...
