Description

Technical Field

[0001] The present application relates to the technical field of basement waterproofing, and in particular to a pre-buried sleeve installation structure for a basement exterior wall. Background Art

[0002] With economic development and the gradual progress of urban renewal, the functions of many buildings need to be adjusted. To meet these needs, underground structures have been renovated. When opening holes behind the exterior walls of basements, the problem of not being able to install water stop rings inside the concrete structure arises.

[0003] Among them, Chinese patent publication number CN211231881U discloses a basement exterior wall rear-opening through-wall pipe waterproofing structure, comprising a basement exterior wall, which, from the inside out, comprises a reinforced concrete exterior wall, an existing building leveling layer, an existing building waterproofing layer structure, and a waterproofing protective wall. The basement exterior wall is provided with a rear-opening through-wall pipe, the rear-opening through-wall pipe having a smaller aperture at the reinforced concrete exterior wall than at the waterproofing protective wall. A waterproof sleeve is provided at one end of the through-wall pipe located outside the reinforced concrete exterior wall. The outer peripheral wall of the waterproof sleeve is provided with a water-stopping outer convex ring. The waterproof sleeve and the through-wall pipe are fixedly connected together by a connecting assembly. A plurality of planted rebars are provided on the outer side of the reinforced concrete exterior wall, each of which is surrounded by annular stirrups. A waterproof mortar structure with embedded planted rebars and annular stirrups is cast outside the waterproof sleeve. This structure effectively reduces the opening area of ​​the reinforced concrete exterior wall, minimizes damage to the original structure, and effectively prevents leakage in the basement exterior wall at the through-wall pipe.

[0004] However, this structure places the through-wall pipe in the rear opening of the reinforced concrete exterior wall. A layer of waterproof mortar is poured onto the reinforced concrete exterior wall to waterproof the gap between the through-wall pipe and the rear opening. However, the waterproof mortar is heavy and needs to be firmly fixed to the reinforced concrete with rebar. This process is not only complex and time-consuming, but also significantly increases the burden on the reinforced concrete sidewall when multiple sets of through-wall pipes need to be installed on the exterior wall. Therefore, a structure is urgently needed to quickly and easily waterproof and seal the sleeves in the rear openings on the exterior walls of basements. Utility Model Content

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] The embodiment of the present application discloses a pre-buried sleeve installation structure for a basement exterior wall.

[0036] Example 1

[0037] Reference Figure 1 and Figure 2 A pre-buried casing installation structure for a basement exterior wall includes a sealing and waterproof mechanism 3 arranged in a rear opening 11 on an exterior wall 1, wherein the sealing and waterproof mechanism 3 is used to seal and waterproof a plurality of casings 2.

[0038] Reference Figure 1 and Figure 2During construction, a rear opening 11 is first opened on the outer wall 1. The rear opening 11 penetrates into the inner side of the outer wall 1. The rear opening 11 facilitates the installation of multiple sets of sleeves 2 at intervals. The rear opening 11 of this embodiment is a rectangular hole structure.

[0039] Reference Figure 1 and Figure 2 The sealing and waterproof mechanism 3 includes a fixing component 31 and a waterproof sealing plate 32, wherein the fixing component 31 is arranged in the rear opening 11, and the fixing component 31 is waterproof and sealed with the inner side of the outer wall 1. Multiple groups of sleeves 2 are passed through the fixing component 31, and the multiple groups of sleeves 2 are fixedly installed on the rear opening 11 through the fixing component 31; the waterproof sealing plate 32 is arranged on the multiple groups of sleeves 2, and the waterproof sealing plate 32 is tightly pressed against the outer wall 1, and the waterproof sealing plate 32 waterproofs the opening of the rear opening 11.

[0040] Reference Figure 2 The fixing assembly 31 includes a fixing plate 311 and a waterproof sealing layer 312. The fixing plate 311 is arranged in the hole of the rear opening 11. The fixing plate 311 is sealed and connected to the water-stop steel plate 12 inside the outer wall 1. The fixing plate 311 is used to fix multiple groups of sleeves 2; the waterproof sealing layer 312 is arranged between the fixing plate 311 and the waterproof sealing plate 32. The side wall of the waterproof sealing layer 312 is tightly sealed on the hole wall of the rear opening 11. The waterproof sealing layer 312 is used to fix multiple groups of sleeves 2.

[0041] Reference Figure 2 Specifically, multiple groups of mounting holes for installing the sleeves 2 are provided at intervals on the fixing plate 311. In order to avoid a large gap between the mounting holes and the pipe sleeves, the multiple groups of mounting holes on the fixing plate 311 of this embodiment are drilled at one time by a water drill, thereby reducing the gap between the sleeves 2 and the mounting holes; then the multiple groups of sleeves 2 are respectively passed through the multiple groups of mounting holes, so that the fixing plate 311 and the plane in which it is located are perpendicular to each other, and then the fixing plate 311 and the multiple groups of sleeves 2 are fixedly connected by welding, and at the same time, the sleeves 2 and the mounting holes are sealed.

[0042] Reference Figure 1 and Figure 2 , place the sealed and welded fixing plate 311 and multiple sets of sleeves 2 into the rear opening 11, and fix the fixing plate 311 to the water-stop steel plate 12 inside the outer wall 1 by welding, so that the axial direction of the multiple sets of sleeves 2 is aligned with the center line of the rear opening 11.

[0043] Reference Figure 1 and Figure 2The structure of the waterproof sealing plate 32 is the same as that of the fixed plate 311. The waterproof sealing plate 32 is also drilled with a water drill to form multiple groups of mounting holes at one time. Multiple groups of sleeves 2 pass through the multiple groups of mounting holes and are sealed and welded, so that the waterproof sealing plate 32 and the outer side walls of the multiple groups of sleeves 2 are sealed. When in use, the waterproof sealing plate 32 is passed through the multiple groups of mounting holes and installed on the multiple groups of sleeves 2, and then the waterproof sealing plate 32 is moved to the designated position so that the four side walls of the waterproof sealing plate 32 are pressed against the side walls of the rear opening 11.

[0044] Reference Figure 2 When the fixing plate 311 and the waterproof sealing plate 32 are installed, a sealed waterproof filling cavity 4 is formed between the fixing plate 311, the waterproof sealing plate 32, the side wall of the rear opening 11 and the outer wall of the multiple groups of sleeves 2. By pouring the perfusion type steel adhesive into the waterproof filling cavity 4, the perfusion type steel adhesive forms a waterproof sealing layer 312 after solidification. The waterproof sealing layer 312 makes the fixing plate 311, the waterproof sealing plate 32, the side wall of the rear opening 11 and the multiple groups of sleeves 2 tightly adhere to form a whole; at the same time, the perfusion type steel adhesive also pours and compacts the gaps between the fixing plate 311 and the side wall of the rear opening 11, and the waterproof sealing plate 32 and the side wall of the rear opening 11, thereby improving the waterproof sealing performance between the fixing plate 311, the waterproof sealing plate 32 and the rear opening 11.

[0045] Reference Figure 2 In order to improve the aesthetics and waterproof effect of the outer wall of the exterior wall 1, a waterproof coating 5 is fixedly installed on the end of the waterproof sealing plate 32 away from the fixed plate 311. The waterproof coating 5 is composed of a waterproof paint evenly applied on the end of the waterproof sealing plate 32 away from the fixed plate 311. The end of the waterproof coating 5 away from the waterproof sealing plate 32 is flush with the outer wall surface of the exterior wall 1.

[0046] The working principle of Example 1 of the present application is:

[0047] The fixing plate 311 is welded and installed on the water-stop steel plate 12 on the inner side of the outer wall 1, and multiple groups of sleeves 2 are sealed and welded on the fixing plate 311, so that the multiple groups of sleeves 2 are fixed on the water-stop steel plate 12 on the inner side of the outer wall 1. The waterproof sealing layer 312 is tightly installed on the fixing plate 311 and supports and fixes the multiple groups of sleeves 2. The waterproof sealing plate 32 is tightly pressed on the end of the waterproof sealing layer 312 away from the fixing plate 311, and the accumulated water in the outer wall 1 is preliminarily sealed and blocked by the waterproof sealing layer 312. The waterproof sealing plate 32 seals and waterproofs the outer end face of the outer wall 1, so as to facilitate the rapid waterproof sealing installation of the sleeve 2 in the rear hole 11 on the outer wall 1 of the basement.

[0048] Example 2

[0049] Reference Figure 3The difference between this embodiment and embodiment 1 is that when the waterproof sealing plate 32 and the waterproof sealing layer 312 are not constructed, multiple groups of sleeves 2 are installed in the rear opening 11 in an air-suspended manner only by the fixing plate 311, which can easily cause damage to the welding points between the sleeves 2 and the fixing plate 311. In order to reduce the force exerted by the multiple groups of sleeves 2 on the fixing plate 311 during this process, a support frame 6 is fixedly installed in the rear opening 11 and on the bottom of the rear opening 11. The support frame 6 is used to support the bottoms of the multiple groups of sleeves 2, thereby causing both ends of the same group of sleeves 2 to be subjected to the supporting force, reducing the probability of damage to the welding points of the fixing plate 311 when the sleeves 2 are suspended in the air. When the waterproof sealing layer 312 is poured, the support frame 6 is pre-buried in the waterproof sealing layer 312, thereby improving the supporting effect of the waterproof sealing layer 312 on the multiple groups of sleeves 2.

[0050] Reference Figure 3 When the cam 312 is in the closed position, the cam 312 is in the closed position, and the cam 312 is in the closed position, so that the cam 312 can be fixed to the wall 1.

[0051] The working principle of Example 2 of the present application is as follows:

[0052] First, the support frame 6 is used to support the end of the multiple groups of sleeves 2 away from the fixed plate 311. The fixed plate 311 and the waterproof sealing plate 32 are formed into a whole with the waterproof sealing layer 312 through the positioning rod 7, thereby improving the fixing effect of the waterproof sealing plate 32 and ultimately improving the waterproof effect of the waterproof sealing plate 32.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
