Embodiment Construction
[0016] Such as figure 1 As shown, a waterproof construction joint structure of a basement exterior wall includes a cast-in-place concrete wall 1 and a post-cast concrete wall 2 formed by segmented layered pouring, and the cast-in-place concrete wall 1 and the post-cast concrete wall A horizontal construction joint 3 is formed between the bodies 2, and a water-stop steel plate 4 that protrudes upwards and bends toward the side facing the water is pre-embedded in the middle of the cast-in-situ concrete wall 1, and the water-stop steel plate 4 is set as U-shaped structure. In this embodiment, the U-shaped opening of the water-stop steel plate 4 faces the side facing the water. Of course, the water-stop steel plate 4 can also be set in an arc-shaped structure. As long as it can prevent water from seeping in, similar structures can be implemented. . The water-stop steel plate 4 is arranged along the casting and forming direction of the cast-in-place concrete wall 1 and the post-c...

Abstract
The invention discloses a waterproof construction joint structure of a basement exterior wall. The waterproof construction joint structure of the basement exterior wall comprises a cast-in-place concrete wall body formed through sectioned and layered pouring, wherein a horizontal construction joint is formed between the cast-in-place concrete wall body and a post-poured concrete wall body, a part of water stop steel plates upwards extruding and bent towards one side of the upstream face is embedded into the middle position of the cast-in-place concrete wall body, the water stop steel plates are arranged in the pouring forming directions of cast-in-place concrete wall body and the post-poured concrete wall body and perpendicular to the horizontal construction joint, and the protruded portions of the water stop steel plates are poured and embedded into the post-poured concrete wall body. U-shaped openings of the water stop steel plates face one side of the upstream face, concrete cracking and water leakage can be well prevented, and the structural strength of two wall bodies at the horizontal construction joint position is enhanced. In addition, by means of waterproof added layers, waterproof layers and waterproof protection layers arranged on two sides of the cast-in-place concrete wall body and on two sides of the post-poured concrete wall body, waterproof effect is greatly improved.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a waterproof construction joint structure of a basement exterior wall during building construction. technical background [0002] During concreting, concrete poured in sections creates a joint at the junction of two pours. The construction joint is not a real "seam". It is just because the concrete poured later exceeds the initial setting time, and there is a joint surface with the concrete poured first. The joint surface is called a construction joint. [0003] The construction joints of the basement exterior wall are weak links in waterproofing. If the construction joints are not properly treated, it will not only affect the strength and durability of the structure, but also cause concrete cracks and water leakage, which will seriously affect the normal use of the project. Therefore, the construction joints of the basement exterior walls are generally Only horizo...
