Embodiment Construction
[0022] Combine below figure 1 , to further illustrate the present invention.
[0023] As shown in the figure, a construction method for anti-seepage of expansion joints includes the following steps:
[0024] Step 1, install the prefabricated formwork 1 and put in the steel bars;
[0025] Step 2, bending the stainless steel sheet 4, thereby dividing the stainless steel sheet into two sections A and B;
[0026] Step 3. Put the stainless steel sheet 4 into the pre-embedded position. The stainless steel sheet 4 and the prefabricated formwork 1 on both sides of the expansion joint are arranged in an oblique shape. A part of the B section of the stainless steel sheet 4 is located in the side wall concrete of the expansion joint. Concrete slabs are poured together, section A is located in the expansion joint, and film is pasted on both sides of section A before pre-embedding;
[0027] Step 4, pouring concrete into the prefabricated formwork 1;
[0028] Step 5. Lift up section A o...

Abstract
The invention discloses an anti-seepage construction method for an expansion joint. The method comprises the following steps that firstly, prefabricated formworks are installed, and steel bars are placed into the prefabricated formworks; secondly, stainless steel sheets are bent, and thus each stainless steel sheet is divided into a section A and a section B; and thirdly, the stainless steel sheets are placed in embedded positions, the stainless steel sheets are arranged obliquely relative to the prefabricated formworks on the two sides of the expansion joint, part of the section B of each stainless steel sheet is located in side wall concrete of the expansion joint, the sections B and a concrete slab are poured together during construction, the sections A are located in the expansion joint, and films are pasted to the two sides of each section A before embedding. According to the anti-seepage construction method, defects of original waterproof construction are overcome, and the effect that seepage is avoided in an implementation area is guaranteed. The construction method has the characteristics that construction is convenient, the construction cost is low, durability is achieved, and the adaptation range is wide, and the anti-seepage construction method can be widely applied to buildings or structures such as houses, bridges, viaducts and tunnels.
Description
technical field [0001] The invention relates to the anti-leakage field in the construction industry, in particular to an anti-leakage construction method for expansion joints in buildings or structures. Background technique [0002] With the development of the economy, there are more and more construction buildings in our country at present, and various materials are widely used in the frame structure filling wall. However, due to the influence of various factors such as technology, materials, craftsmanship, and construction quality, cracks on the top and outer walls of buildings are more common, which will cause water seepage in the walls and damage the interior, and even more seriously, it will affect the building. This series of problems has become a common quality problem that is difficult to cure in the construction industry. [0003] With the advancement of the industrialization of buildings, prefabrication and pipeline integration have become the trend and necessity ...
