Description

Basement outer wall waterproof concrete construction joint structure

Technical Field

The utility model relates to a building engineering construction technical field, in particular to basement outer wall waterproof concrete construction joint structure.

Background

With the vigorous development of Chinese economic construction, the appearance of intensive urbanization determines that middle-rise and high-rise buildings become the main development direction of building engineering, the high possession of people's air defense and automobiles also leads the city buildings to turn to underground space extension, and more basement engineering projects are available. In basement engineering construction, the most important is seepage prevention of construction joints. But constructors generally consider that basement waterproofing is often neglected as long as the structure has no problem.

As is well known, a construction joint (construction joint) refers to a joint formed between first and second concretes during a concrete casting process, due to a design requirement or a construction requirement of a segmental casting. The construction joint is not a real existing joint, and only because the initial setting time of the first poured concrete is longer than the initial setting time, a joint surface exists between the first poured concrete and the later poured concrete, and the joint surface is called as the construction joint. Under a long-time humid environment, the basement has the problems that concrete aggregate is concentrated, concrete is loose, stubble connection is obvious, and water leaks indoors along the gaps. Directly results in the strength reduction of the basement outer wall, and finally suffers damage to cause irreparable loss. Therefore, the waterproof engineering is particularly important in the construction stage of the basement exterior wall.

At present, waterproof concrete is generally continuously poured, construction joints are rarely left, or water is prevented from permeating by leaving the construction joints as convex joints and step joints, and embedding metal water stops or adhering BW water stops in the flat joints when the construction joints are left as the flat joints. Specifically, a water stop is generally arranged along the length direction of the construction joint, but water seepage can still occur at the joint of the water stop and concrete, so that the water seepage cannot be well prevented in the prior art.

For example, patent CN 203755350U discloses a horizontal construction joint structure of waterproof concrete for basement exterior wall, which comprises a cushion layer, a foundation slab and an exterior wall poured with concrete containing waterproof concrete, a water-stop steel plate, a rubber water-stop strip, a top plate, a horizontal construction joint of foundation guide wall and a horizontal construction joint at the position above the guide wall; the outer wall is including leading the wall and leading the outer wall at the position above the wall, and the horizontal construction joint of wall is led to the basis sets up in leading wall department, is greater than 300mm with the distance of soleplate upper surface, leads the horizontal construction joint of position above the wall to set up on the roof and under the roof, and the outer wall of the horizontal construction joint department of wall is led to the basis sets up the stagnant water steel sheet between two parties, sets up the rubber sealing strip between two parties on the roof and under the roof, rubber sealing strip width 30mm, height 20mm adds waterproof concrete in the concrete, sets up the stagnant water steel sheet in the outer wall of the horizontal construction joint department of wall is led to the basis, sets up the rubber sealing strip in the outer wall of the horizontal construction joint department of position above the wall, effectively prevents basement outer wall infiltration. However, only one water-stopping steel plate or rubber water-stopping strip is arranged on each construction joint, and the water seepage condition can occur at the joint of each water-stopping steel plate or rubber water-stopping strip and the concrete wall, so that the water seepage prevention effect is not good enough.
