Anti-leakage construction method suitable for horizontal expansion joint

Abstract

Provided is an anti-leakage construction method suitable for a horizontal expansion joint. The method includes the steps that a, when a top plate structure is poured, a concrete structure reverse ridge is arranged at the position away from the edge of an expansion joint structure; b, the edge of the expansion joint structure is coated with a two-component polysulfide sealant, and V-shaped elementswith horizontal edges at the two sides are installed on the edge of the expansion joint structure and sealed through the sealant; c, the two edges of the V-shaped elements are fixed to the structuraledges of the two sides of the expansion joint through expansion bolts correspondingly; d, the V-shaped elements of the expansion joint is filled with waterproof factice in an embedded mode; e, a first waterproof coiled material is laid on the waterproof factice, and the two sides of the coiled material completely wrap the concrete structure reverse ridge; f, the first waterproof coiled material is filled with the waterproof factice in an embedded mode; g, a second waterproof coiled material is paved on the waterproof factice; and h, a fine aggregate concrete rigid protection layer is manufactured on the second waterproof coiled material. According to the anti-leakage construction method suitable for the horizontal expansion joint, the construction process is simplified, the construction benefit is increased, the construction quality is guaranteed, and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to an anti-leakage construction method suitable for horizontal expansion joints. Background technique [0002] With the rapid development of the economy and the rapid development of urbanization, the construction of large buildings has ushered in a golden period of development. Expansion joints refer to when the plane size of the building is large, in order to prevent the internal force of the building components due to climate temperature changes (thermal expansion, cold contraction) and concrete shrinkage to cause cracks or damage to the structure, in order to release this A structural joint arranged at an appropriate position along the construction joint direction of a building or structure due to internal forces. The expansion joint is to divide the building components above the foundation such as walls, floors, roofs, etc. into two independent parts, so that the ...

Problems solved by technology

Moreover, the pre-embedded angle steel has high requirements for positioning accuracy and welding quality. Once the positioning accuracy is not enough, it will be difficult to fit the V-shaped steel plate closely with the pre-embedded angle steel when installing the V-shaped steel plate later. The welding quality is not high, and the edge is prone to water leakage.

Expansion joint leakage is difficult to maintain. After the main body is capped, the operation surface of the expansion joint is narrow and concrete transportation is difficult, which increases material loss, labor, and construction period, thereby greatly increasing construction costs.

The traditional expansion joint construction method has a slow construction progress and a high risk of leakage
