Embodiment 1

[0034] Such as Figure 1~5 As shown, the outer side of the existing wall 1 is pasted with an outer wall waterproof membrane layer 2 to meet the waterproof requirements of the wall. When adding a casing, it is necessary to drill a hole slightly larger than the size of the casing, and at the same time remove the waterproof membrane in the same range to form a wall opening 3, in order to ensure that the filled concrete can be properly injected into the hole after the casing is arranged 5 , it is necessary to open a 50-100mm grouting hole 4 above the inner side of the wall opening 3.

[0035] In this embodiment, the diameter of the casing 9 is d, the diameter of the flange 6 and the wing disc 7 is (d+100) mm, the diameter of the cover plate 8 is (d+250) mm, the flange 6, the wing disc 7, The cover plate 8 and the casing 9 are integrally formed metal components, which are placed in the casing hole 3 pre-opened in the wall from the outdoor to the indoor direction. On the indoor si...

Abstract

The invention provides a wall surface rear-mounted type waterproof sleeve assembly and a wall body structure with the wall surface rear-mounted type waterproof sleeve assembly. The wall surface rear-mounted type waterproof sleeve assembly is arranged on an existing wall body where a sleeve hole is formed, and comprises a sleeve, a grouting template and a steel plate strip. The sleeve, the grouting template and the steel plate strip are sequentially arranged from outside to inside. A flange is arranged at one end of the sleeve, a covering plate is arranged at the other end of the sleeve, and a wing disc is arranged on the periphery of the sleeve. The diameter of the covering plate or the diameter of a inscribed circle is larger than that of the sleeve hole, the diameter of the flange and the diameter of the wing disc are smaller than the diameter of the sleeve hole, and a plurality of installation holes are formed in the flange. Grouting vent holes and stud holes are formed in the grouting template, and stud holes are also formed in the steel plate strip. The wall body structure which is installed by adopting the wall surface rear-mounted type waterproof sleeve assembly is convenient to construct and good in waterproof effect, the tedious operation in the process of conventional sleeve construction is avoided, the construction efficiency can be improved, and the risk of water leakage is also reduced.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a wall rear-mounted waterproof sleeve assembly and its wall structure, which is mainly used in the case of adding sleeves to the wall surface of an existing waterproof coiled material layer. Background technique [0002] In construction projects, underground waterproofing is very important, and water leakage at individual points directly affects the overall waterproofing requirements. According to the functional requirements of the building, rigid or flexible embedded casings are usually provided on the outer walls. For the embedded casings on the outer walls below the ground, the waterproof joints are more prone to problems in engineering. In actual projects, casings are often added after the waterproofing of the underground exterior wall is completed due to omissions and other circumstances. For the construction of the back-up casing, it is necessary to open a ...
