Description

Technical Field

[0001] This application is used in the technical field of exterior wall waterproofing and seepage prevention, and particularly relates to an exterior wall construction system. Background Art

[0002] The most prominent common quality problems in basement engineering are cracks in the exterior wall. The exterior wall of the basement is not only a load-bearing structure of the main structure but also a waterproof system. Cracks in the exterior wall of the basement bring great inconvenience to people's living and life. Moreover, once water seepage and leakage occur in the exterior wall of the basement, it is quite difficult to handle.

[0003] And during the construction of the exterior wall pouring, an external scaffold needs to be erected on the support structure. When the distance between the support structure and the location where the external scaffold needs to be erected is relatively close, there is not enough space to erect the external scaffold. If the exterior wall pouring is directly carried out, it will result in a high construction cost for the exterior wall. Utility Model Content

[0031] The embodiment of this application provides an exterior wall construction system. Refer to Figure 1 and Figure 2 , including

[0032] a support structure 100, and embedded steel bars 110 are arranged inside the support structure 100;

[0033] a masonry structure 200, and the masonry structure 200 is arranged inside the support structure 100;

[0034] a formwork 300, the formwork 300 is located inside the masonry structure 200, and a pouring space 400 for forming the exterior wall is formed between the masonry structure 200 and the formwork 300;

[0035] a grouting pipe 500, the inner end of the embedded steel bar 110 passes through the masonry structure 200 and extends into the pouring space 400, the outer end of the grouting pipe 500 is connected to the grouting pipe 500, and the outer end of the grouting pipe 500 is connected to the formwork 300;

[0036] A sealing structure 111 is provided on the outer periphery of the embedded steel bars 110. The sealing structure 111 is located inside the masonry structure 200, and the outer end of the grouting pipe 500 abuts against the sealing structure 111.

[0037] This exterior wall construction system sets a sealing structure 111 at the joint between the embedded steel bars 110 and the masonry structure 200, which can effectively improve the anti-seepage and anti-leakage effect of the exterior wall and enhance the anti-seepage situation of the structure. After grouting the grouting pipe 500, it is ensured that the outer end of the grouting pipe 500 abuts against the sealing structure 111. The formwork 300 provides a temporary support and enclosure structure for concrete pouring. The grouting pipe 500 is connected to the embedded steel bars 110 to ensure that the concrete maintains the required shape during pouring and solidification, can effectively ensure the size of the concrete after pouring and forming, and can also bear the weight and pressure of the concrete, meet the extrusion of the formwork 300 during concrete pouring and vibration, and can effectively avoid the formwork 300 from cracking and bursting. At the same time, the grouting pipe 500 plays the role of a tie rod to ensure the overall stability of this exterior wall construction system. By setting the masonry structure 200 to be applicable in a narrow space, setting structures such as the grouting pipe 500 and the embedded steel bars 110 can effectively stabilize the single-sided formwork system, reduce the erection of the external scaffold, save construction and construction time, solve the instability of the underground single-sided formwork and the poor waterproof effect, and is used for the non-formwork space of the underground exterior wall to solve the waterproof and anti-seepage construction system of the underground exterior wall without an external formwork system. By grouting the grouting pipe 500, the anti-seepage and water-stopping effect can be effectively achieved, with fast working hours, simplicity, convenience, and no impact on the compaction during pouring. The construction technology has remarkable effects on the waterproofing and crack repair of the underground single-sided formwork exterior wall, is flexible and convenient, and has broad prospects for popularization and application.

[0038] In some embodiments, a water stop plug 510 is provided at the outer end of the grouting pipe 500. The water stop plug 510 abuts against the inner side of the sealing structure 111. The water stop plug 510 is made of extruded foam, and the extruded foam is a water-swellable material. Using the extruded foam water stop plug can prevent the cement slurry in the concrete from flowing into the grouting pipe 500 during the concrete pouring process and avoid contamination inside the grouting pipe 500.

[0039] In some embodiments, a waterproof coiled material 210 is laid on the inner side of the masonry structure 200, and a waterproof coating 220 is provided between the inner side of the masonry structure 200 and the waterproof coiled material 210. The waterproof coiled material 210 is a 1.5-mm-thick rubber self-adhesive film pre-laid waterproof coiled material, and the waterproof coating 220 is a 1.5-mm-thick polyurethane waterproof coating (inverted hanging type). The waterproof film formed after the waterproof coating 220 applied on the masonry brick wall is cured has certain extensibility, elastoplasticity, crack resistance, impermeability and weather resistance, and can play a role in waterproofing, anti-seepage and protection; additionally, a 1.5-mm-thick rubber self-adhesive film pre-laid waterproof coiled material is added, that is, a round of waterproofing is carried out again on the basis of single-layer waterproofing, which is an effect of improving the thickness and density of the waterproof layer. Doing so can reduce problems such as penetration and aging, and improve the waterproof effect. This double-layer waterproof structure is applicable to situations where the building requirements are particularly high or the base conditions are relatively complex. Compared with single-layer waterproofing, the advantage of double-layer waterproofing is that it can increase the thickness and density of the waterproofing and improve the quality of the waterproof layer.

[0040] In some embodiments, the sealing structure 111 is caulking paste coated on the inner side of the waterproof coiled material 210, that is, caulking paste is used for plugging at the place where the embedded steel bar 110 penetrates through the waterproof coiled material 210, and waterproof asphalt caulking paste is used at the puncture part of the embedded steel bar 110 and the joint part of the waterproof coiled material 210. The caulking paste has characteristics such as good adhesiveness, heat resistance, oil retention, low-temperature flexibility, low volatility and suitable workability, etc., can remain stable within the temperature range of +80°C to -20°C, has a service life of more than ten years and is not easy to age. In addition, the caulking paste also has good bonding and extension properties, is applicable to the changes of the roof base caused by reasons such as thermal expansion, cold shrinkage, vibration and settlement, and has certain acid and alkali resistance and oil resistance, and strong anti-aging property.

[0041] In some embodiments, the inner end of the grouting pipe 500 extends to the inner side of the formwork 300. The grouting pipe 500 is provided with external threads, and the outer side of the formwork 300 is provided with a first nut 310 that mates with the external threads. A rubber plug is arranged between the first nut 310 and the formwork 300. The inner side of the formwork 300 is provided with a second nut 320 that mates with the external threads. The first nut 310 and the second nut 320 can effectively position the formwork and can effectively ensure the thickness of the basement exterior wall. The rubber plug can be used for plugging, can block the concrete from leaking out of the holes on the formwork 300 during concrete pouring, and at the same time ensures the aesthetics after the wall surface is plastered with mortar.

[0042] In some embodiments, a first support pipe 330 and a second support pipe 340 are arranged horizontally on the inner side of the formwork 300. The grouting pipe 500 is clamped between the first support pipe 330 and the second support pipe 340. A wooden square 360 is arranged between the formwork 300 and the support structure composed of the first support pipe 330 and the second support pipe 340, which is convenient for dispersing the load received by the formwork 300 onto the wooden square structure to prevent distortion or deformation. The wooden square 360 provides effective support for the formwork 300. The wooden square 360 is arranged in the height direction, and multiple wooden squares 360 are arranged horizontally, serving as longitudinal supports. Both the first support pipe 330 and the second support pipe 340 are φ48 steel pipes. An internal force system is formed among the first nut 310, the rubber plug, the second nut 320, the formwork 300, the wooden square 360, the first support pipe 330, and the second support pipe 340. The first support pipe 330, the second support pipe 340, and the wooden square 360 form a horizontal and longitudinal force system, which can meet the extrusion of the formwork 300 during concrete pouring.

[0043] In some embodiments, a butterfly clip 350 is arranged on the outer side of the second nut 320. The butterfly clip 350 can fix the first support pipe 330 and the second support pipe 340, that is, the butterfly clip 350 and the second nut 320 are used to fix the first support pipe 330 and the second support pipe 340, thereby playing a role in formwork reinforcement.

[0044] In some embodiments, a water stop ring 410 is arranged in the pouring space 400, and the water stop ring 410 is welded to the outer circumference of the grouting pipe 500.

[0045] In some embodiments, a bottom plate 600 is arranged on the inner side of the support structure 100. The masonry structure 200, the pouring space 400, and the formwork 300 are all located on the top of the bottom plate 600. An inclined support 610 is arranged between the bottom plate 600 and the formwork 300 to form a single-sided formwork system.

[0046] In some embodiments, the masonry structure 200 is made of lime-sand bricks. When constructing the embedded steel bars 110, high-performance implanting glue - epoxy structural implanting glue is used. First, layout lines are marked on the support structure 100, then holes are drilled and washed. After the hole positions are cleaned and dried, epoxy structural implanting glue is injected, and then the embedded steel bars 110 are implanted. After curing through maintenance, a pull-out test (spot check) is carried out. The masonry range line is marked, and lime-sand bricks are used to build the masonry structure 200 on the inner side of the support structure 100. One side of the lime-sand bricks is leveled with 20mm 1:3 cement mortar. During construction, first, a 1.5mm thick polyurethane waterproof coating is applied on the cement mortar, then the isolation paper of the waterproof coiled material is peeled off, and a 1.5mm thick rubber self-adhesive film pre-laid waterproof coiled material is pasted on the waterproof coating.
