Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a method for sealing holes around a through-wall pipe. Background Technology

[0002] Currently, with the development of society and economy, in order to meet the basic aesthetic needs of modern people, more and more buildings are choosing same-floor drainage for bathrooms instead of cross-floor drainage. However, same-floor drainage requires the installation of lateral drainage pipes on the bathroom sump. The traditional method is to directly use sealant or dry cement to seal the pipes, and support rods are also required. This method is not very effective and has a high probability of leakage. On the other hand, the cost of setting water-stop joints for pre-embedded drainage pipes is too high, which is not conducive to reducing project costs. At the same time, the above problems will also occur for non-pre-embedded and post-opening wall penetration pipes in basements. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a method for sealing holes around through-wall pipes.

[0004] To achieve the above objectives, the technical solution adopted by this invention is: a method for sealing holes around a through-wall pipe, comprising the following steps:

[0005] Step 1: Pre-treat the sleeves around the through-wall pipe and pre-fix the through-wall pipe;

[0006] Step 2: Assemble the formwork around the perimeter of the through-wall pipe;

[0007] Step 3: Seal the area between the formwork and the wall.

[0008] Step 4: Pour the grout between the formwork and the wall;

[0009] Step 5: Remove the formwork after the grout has cured to the appropriate strength.

[0010] Preferably, the template includes an upper module and a lower module. The upper module has an arc-shaped section at one end, which fits with the outer periphery of the through-wall pipe. The lower module has an arc-shaped section at the end near the upper module, which fits with the outer periphery of the through-wall pipe. The upper module and the lower module are detachably connected.

[0011] Preferably, a plurality of upper connecting blocks are installed above the upper module, and a plurality of lower connecting blocks are installed above the lower module; the plurality of upper connecting blocks and the corresponding lower connecting blocks are detachably connected by bolts.

[0012] Preferably, the template further includes a feeding component with a feeding port, a pin plate installed on the outer periphery of the feeding component, a plurality of protrusions installed below the pin plate, and a plurality of grooves provided at the end of the upper module away from the arc, wherein the protrusions and grooves cooperate with each other.

[0013] Preferably, step one involves using an electric pick to remove the sleeves around the pre-embedded through-wall pipe and roughening the base surface inside the holes around the through-wall pipe; laying out and measuring the perimeter of the through-wall pipe and using a hanger to pre-fix the through-wall pipe.

[0014] Preferably, in step two: the arc shape one of the upper module is fitted with the outer periphery of the through-wall pipe, the arc shape two of the lower module is fitted with the outer periphery of the through-wall pipe, and the upper connecting block of the upper module and the lower connecting block of the lower module are detachably connected by bolts. Finally, the protrusion one of the pin plate on the outer periphery of the feeding part is fitted with the groove one of the upper module.

[0015] Preferably, in step three: use a caulking gun to apply sealant to the left and right sides of the upper module between it and the wall, and use a caulking gun to apply sealant to the left, right, and bottom sides of the lower module between it and the wall.

[0016] Preferably, in step four: the prepared slurry is poured through the feeding port of the feeding device, and the slurry enters the position between the upper module and the wall along the feeding port, and then enters the position between the lower module and the wall.

[0017] Preferably, in step five: keep the upper and lower modules for a period of time until the slurry solidifies and reaches a suitable strength, use a utility knife to cut off the sealant, separate the pin plate on the outer periphery of the feeding part from the upper module, then remove the bolts between the upper connecting block of the upper module and the lower connecting block of the lower module, and finally remove the upper and lower modules from the outer periphery of the through-wall pipe.

[0018] Preferably, the grout is a fine aggregate concrete grout or a grouting material.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0020] (1) Existing pre-embedded drainage pipes are directly sealed with sealant or dry cement. However, the present invention uses a template to be set on the outer periphery of the through-wall pipe, and the template is sealed with the wall. Then, grout is poured between the template and the wall, and the grout is solidified to seal the holes around the through-wall pipe to prevent subsequent drainage pipe leakage.

[0021] (2) Existing sealing methods require the addition of support rods to the pre-embedded through-wall drainage pipes. However, the present invention adopts a detachable connection between the upper and lower modules, and sealant is applied to the position between the upper and lower modules and the wall. This changes the method from adding support rods to a self-locking support mode, which improves the quality of hole processing around the through-wall pipes, increases construction efficiency, and saves manpower and resources.

[0022] (3) Existing pre-embedded drainage pipes are equipped with water-stop joints, while the upper and lower modules of the present invention are detachably connected by bolts, which indirectly saves templates and hole-blocking materials. Moreover, the bolt connection installation method increases the turnover of materials, and there is no construction waste or pollution on site.

[0023] (4) Multiple grooves are provided on the upper part of the upper module, and multiple protrusions are installed below the pin plate on the outer periphery of the feeding component. The grooves and protrusions cooperate to make the feeding port end of the feeding component located between the upper module and the wall, so that all the injected slurry can enter between the template and the wall, reducing resource waste.

[0034] To better understand the above-mentioned objectives, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0036] Example 1

[0037] The following is in conjunction with the appendix Figures 1-7 To further describe the present invention, a method for sealing holes around a through-wall pipe is provided, such as... Figures 1-7 As shown, it includes the following steps:

[0038] Step 1: Pre-treat the sleeves 3 around the through-wall pipe 2, and pre-fix the through-wall pipe 2;

[0039] Step 2: Assemble the formwork around the outer perimeter of the through-wall pipe 2;

[0040] Step 3: Seal the area between the formwork and wall 1;

[0041] Step 4: Pour the grout between the formwork and wall 1;

[0042] Step 5: Remove the formwork after the grout has cured to the appropriate strength.

[0043] like Figures 4-7 As shown, the template includes an upper module 4 and a lower module 5. The upper module 4 has an arc-shaped section at its end, which fits with the outer periphery of the through-wall pipe 2. The lower module 5 has an arc-shaped section at its end near the upper module 4, which fits with the outer periphery of the through-wall pipe 2. The arc-shaped section and the arc-shaped section together form a circle.

[0044] like Figures 4-7 As shown, multiple upper connecting blocks 10 are installed above the upper module 4, and multiple lower connecting blocks 12 are installed above the lower module 5. The multiple upper connecting blocks 10 and the corresponding lower connecting blocks 12 are detachably connected by bolts 11.

[0045] like Figures 4-7As shown, the template also includes a feeding component 6, which has a feeding port. A pin plate 7 is installed on the outer periphery of the feeding component 6. Multiple protrusions 9 are installed below the pin plate 7. Multiple grooves are provided at the end of the upper module 4 away from the arc shape. The protrusions 9 and the grooves cooperate to place the feeding component 6.

[0046] like Figure 1 As shown, step one includes: using an electric pick to remove the sleeves 3 around the pre-embedded through-wall pipe 2, and roughening the base surface inside the holes around the through-wall pipe 2. The roughening process is to remove the surface crust from the base surface inside the holes around the through-wall pipe 2, thereby forming a rough surface; laying out and measuring the perimeter of the through-wall pipe 2, and using a hanger to pre-fix the through-wall pipe 2 to prevent the through-wall pipe 2 from moving after the inside of the holes around the through-wall pipe 2 is roughened.

[0047] like Figures 1-7 As shown, step two includes: fitting the arc shape of the upper module 4 to the outer periphery of the through-wall pipe 2, fitting the arc shape of the lower module 5 to the outer periphery of the through-wall pipe 2, and detachably connecting the upper connecting block 10 of the upper module 4 and the lower connecting block 12 of the lower module 5 with bolts 11. Finally, fitting the protrusion 9 of the pin plate 7 on the outer periphery of the feeding component 6 to the groove 1 of the upper module 4, so that the feeding port in the feeding component 6 is located near the end of the upper module 4 between the upper module 4 and the wall 1.

[0048] like Figures 1-7 As shown, step three includes: using a glue gun to apply sealant 8 to the left and right sides of the upper module 4 between it and the wall 1, and using a glue gun to apply sealant 8 to the left, right, and bottom sides of the lower module 5 between it and the wall 1. The width of the sealant 8 applied is 2mm-5mm.

[0049] like Figures 1-7 As shown, step four includes: pouring the prepared slurry through the feeding port of the feeding component 6. The slurry enters the position between the upper module 4 and the wall 1 along the feeding port, and then enters the position between the lower module 5 and the wall 1. Since sealant 8 is applied to the left and right sides of the upper module 4 and the position between the upper module 4 and the wall 1, and sealant 8 is applied to the lower side, left side and right side of the lower module 5 and the position between the lower module 5 and the wall 1, the slurry will be located in the position between the lower module 5 and the upper module 4 and the wall 1.

[0050] like Figures 1-7 As shown, step five includes: keeping the upper module 4 and lower module 5 for a period of time until the grout solidifies and reaches a suitable strength (7 days); using a utility knife to cut off the sealant 8 between the upper module 4 and lower module 5 and the wall 1; separating the pin plate 7 on the outer periphery of the feeding part 6 from the upper module 4; removing the bolts 11 between the upper connecting block 10 of the upper module 4 and the lower connecting block 12 of the lower module 5; and finally removing the upper module 4 and lower module 5 from the outer periphery of the through-wall pipe 2.

[0051] In this invention, before the grout is poured in, the sides of the upper module 4 and the lower module 5 near the wall 1 need to be coated with oil to prevent the upper module 4 and the lower module 5 from being difficult to remove after the grout solidifies.

[0052] In this invention, multiple rows of protrusions are installed below the pin plate 7, with adjacent protrusions spaced a certain distance apart, and multiple protrusions 9 forming a protrusion group.

[0053] In this invention, a slurry with good fluidity is selected, such as fine aggregate concrete slurry or grouting material.

[0054] In this invention, after the sealing construction between the template perimeter and the wall 1 is completed in step three, the pre-fixed hanger rods of the through-wall pipe 2 in step one need to be removed.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
