Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to the field of external wall penetration sleeve construction, and specifically to a waterproof construction device for external wall penetration sleeves. Background Art

[0002] In the rapidly developing construction industry, the improvement of project quality has become the unremitting pursuit of more and more construction companies. In the construction industry, the risk of leakage of the basement exterior wall is an engineering problem that has always existed and is difficult to solve. There are many pipes penetrating the exterior wall of the basement, and there are often more than five or six sleeves side by side on the exterior wall. The one-time forming effect of the concrete at this location has become the key to preventing leakage of the basement exterior wall, which directly affects the quality of the project. In the reserved wall sleeves on the concrete exterior wall, due to the loose sealing of traditional processes, this location is prone to quality problems such as leakage and slag inclusion, which increases the amount of maintenance while also increasing the risk of leakage of the exterior wall. Because the sleeves are very dense and the spacing between the pipes and the pipe sleeves is very small, the waterproof membrane here is difficult to construct, and it is not firmly attached to the already formed concrete wall base, resulting in poor construction quality. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a waterproof construction device for the outer wall through-wall sleeve. Before pouring the concrete outer wall, the outer wall template with the waterproof coiled material layer is assembled and pre-installed with each sleeve, and then poured, so that the waterproof coiled material layer can be firmly fixed on the formed outer wall surface, solving the leakage problem caused by the difficulty of waterproof construction around the sleeve due to unevenness, and the effect is remarkable. Compared with other methods, it has low investment cost, easy operation, and has achieved obvious social benefits, environmental benefits and economic benefits.

[0004] The utility model is realized by the following technical solutions:

[0005] A waterproof construction device for an external wall through-wall sleeve, comprising an external wall template, wherein a plurality of through holes for allowing the sleeve to pass through are arranged on the external wall template according to preset sleeve distribution positions;

[0006] The inner side of the exterior wall formwork is provided with a waterproof coiled material layer, and the waterproof coiled material layer is provided with a plurality of through holes, and the through holes correspond to and overlap with the perforations one by one;

[0007] The edge of the waterproof coiled material layer is fixed on the inner side of the exterior wall formwork by a plurality of long nails.

[0008] Furthermore, the waterproof membrane layer is made of 2-3 mm thick SBS modified asphalt waterproof membrane.

[0009] Furthermore, an inverted cone-shaped nail head is provided at one end of the long nail located outside the waterproof coiled material layer.

[0010] Furthermore, the waterproof coiled material layer is rectangular, and a plurality of long spikes are installed on the edge of the waterproof coiled material layer, and the spacing between the long spikes is 300-400 mm.

[0011] Furthermore, the exterior wall formwork is provided with a mounting hole allowing the long nail to pass through, and one end of the long nail away from the nail head is threadedly connected with a positioning nut.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are as follows:

[0013] 1. The edge of the waterproofing membrane layer is fixed on the inner side of the exterior wall formwork by a plurality of long nails. The through holes on the waterproofing membrane layer correspond to and overlap with the perforations on the exterior wall formwork one by one, allowing multiple sleeves to pass through. Before pouring the concrete exterior wall, the exterior wall formwork with the waterproofing membrane layer is assembled and pre-installed with each sleeve, and then poured, so that the waterproofing membrane layer can be firmly fixed on the formed exterior wall surface, solving the leakage problem caused by the difficulty of waterproofing construction around the sleeve, with remarkable results;

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] In the description of the utility model, it is necessary to understand that the directions or positional relationships indicated by the terms "front", "rear", "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model.

[0024] like Figure 1-2 As shown, this embodiment discloses a waterproof construction device for an exterior wall through-wall sleeve, including an exterior wall template 1, on which a plurality of perforations for allowing the sleeve to pass are processed according to the preset sleeve distribution position, quantity, size and other parameters during the specific construction. A waterproof coiled material layer 2 is installed on the inner side of the exterior wall template 1, and a plurality of through holes 3 are processed on the waterproof coiled material layer 2, and the through holes 3 correspond to and overlap with the perforations one by one. Since the exterior wall needs to be disassembled after solidification and forming in the later stage, and the waterproof coiled material layer 2 needs to be firmly retained on the exterior wall, the edge of the waterproof coiled material layer 2 is fixed to the inner side of the exterior wall template 1 by a plurality of long nails 4.

[0025] In this embodiment, the waterproofing coiled material layer 2 is made of 3 mm thick SBS modified asphalt waterproofing coiled material, and the waterproofing coiled material layer 2 is rectangular. The edge of the waterproofing coiled material layer 2 has a plurality of evenly distributed long nails 4, and the spacing between the long nails 4 is 300 mm. In order to facilitate the long nails 4 to be pulled out from the waterproofing coiled material layer 2, an inverted cone-shaped nail head 5 is provided at one end of the long nail 4 located outside the waterproofing coiled material layer 2.

[0026] like Figure 3 As shown, in order to be able to recycle the long nail 4, a mounting hole allowing the long nail 4 to pass through can be processed on the exterior wall formwork 1, and the end of the long nail 4 away from the nail head 5 is threadedly connected with a positioning nut 6. When the long nail 4 passes through the mounting hole with the waterproof membrane layer 2, the waterproof membrane layer 2 is fixed to the exterior wall formwork 1 by assembling the positioning nut 6.

[0027] The specific construction process of the waterproof construction device for the external wall through-wall sleeve of the utility model is as follows:

[0028] 1. External wall column reinforcement binding

[0029] Tie up the reinforcement for the exterior wall columns according to the reinforcement model and spacing designed in the drawings. At this location, pay attention to fully tying the reinforcement.

[0030] 2. Install and accept the external wall bushing

[0031] According to the position, spacing and size designed in the drawings, after the external wall reinforcement is tied, install the external wall sleeve. After the sleeve is installed, determine whether additional reinforcement is needed based on the sleeve diameter and the requirements of the drawings. If necessary, tie additional reinforcement around the sleeve to ensure that the structural force meets the design requirements. After the above work is completed, report to the supervision unit for acceptance after self-inspection.

[0032] 3. Cut the template and 3mm thick SBS modified asphalt waterproof membrane of appropriate size and position them on the exterior wall template and waterproof membrane layer according to the installed casing position.

[0033] Select a template of appropriate size according to the layout of the exterior wall template, and cut a 3mm thick SBS modified asphalt waterproof membrane of appropriate size as the waterproof membrane layer. The four sides of the waterproof membrane layer are about 150mm longer than the edge of the wall sleeve, and then position it on the waterproof membrane and the exterior wall template according to the position and size of the wall sleeve.

[0034] 4. Drill holes on the waterproof membrane layer and exterior wall formwork according to the positioning

[0035] After positioning is completed, select a suitable hole opener according to the diameter of the casing, and make holes in the waterproof membrane layer and the exterior wall formwork at the determined location.

[0036] 5. Nail the waterproof membrane layer to the inside of the outer wall formwork with 1cm long nails.

[0037] Fix the waterproof membrane layer with holes on the inner side of the exterior wall formwork with 10mm long nails (carpenter nails are sufficient). Before fixing, check that the opening positions of the two must coincide. To ensure that the waterproof membrane layer is firmly nailed to the formwork, except for the four corners, the rest of the positions must be fixed with a nail spacing of 300mm.

[0038] 6. External wall formwork reinforcement

[0039] Install the exterior wall formwork in place according to the formwork layout, then install the secondary and main purlins outside the exterior wall formwork, and then use water-stop screws of appropriate sizes and mountain-shaped cards to reinforce the formwork.

[0040] 7. Concrete pouring after the top slab reinforcement acceptance is completed

[0041] After the top plate reinforcement is tied and accepted, concrete pouring begins. Before pouring, the top plate surface and the wall column formwork surface are sprinkled with water to moisten them, but no water accumulation is allowed. The concrete strength grade is in accordance with the design requirements of the drawings. During the pouring process, pay attention to vibrating and compacting the concentrated areas of the outer wall sleeves.

[0042] 8. Remove the formwork after the concrete reaches a certain strength

[0043] When the concrete strength reaches the design strength value, the formwork is removed. When removing, be careful not to use brute force to avoid damage to the already formed concrete surface and wall sleeve. After the exterior wall formwork is removed, the long nails are separated from the waterproof membrane layer, and the waterproof membrane layer remains on the exterior wall surface of the poured concrete.
