Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a building exterior wall waterproofing testing device for supervision. Background Technology

[0002] During the final acceptance phase of a residential building project, the supervisors need to conduct on-site testing of the waterproofing performance of the building's exterior walls. The goal is to verify the wall's resistance to seepage under severe hydrological conditions such as heavy rainfall and continuous water spray, in order to prevent problems such as dampness on interior walls, wallpaper peeling, and mold growth caused by water seepage after the building is handed over for use.

[0003] However, the current mainstream method for fixing exterior wall waterproofing testing devices on exterior walls mostly relies on wall groove anchoring. In practice, the supervision team first needs to use tools such as electric drills and cutting machines to chisel rectangular or circular grooves with a depth of 5-15mm and a width of 8-12mm in the exterior wall area to be tested (usually around the perimeter of each test area). The number of grooves depends on the size of the spray device (generally 4-6 grooves are needed per square meter of test area). Then, the metal fixing bracket of the spray device is embedded into the groove and tightened to the wall base (such as concrete or aerated concrete blocks) with expansion bolts or special anchoring adhesive to ensure that the spray head can be stably aligned with the test area. After fixing, the water pipe is connected and the water pump is started to spray continuously for 30 minutes to 2 hours at a water pressure of 0.1-0.3MPa to simulate the intensity of moderate to heavy rain in nature and observe whether there are any signs of water seepage on the inside of the wall.

[0004] This method of fixing by grooving causes physical damage to the completed exterior walls. Specifically, the grooves directly damage the decorative and protective layers of the wall, exposing the base layer. Even if repairs are made later, problems such as hollowing, cracking, and color difference at the repair site may occur due to the difference in shrinkage rate between the repair material and the original wall material and insufficient bonding strength. This affects the integrity of the building's appearance and its long-term waterproof performance. Moreover, the rework and repair process after grooving is complicated and costly.

[0036] In one embodiment of this utility model, a building exterior wall waterproofing testing device is provided for supervising the waterproofing performance of building exterior walls. Unlike traditional testing devices that rely on wall grooves for anchoring, the testing device provided in this embodiment is fixed to the windowsill of the wall, eliminating the need for grooves on the exterior wall and avoiding physical damage to the exterior wall.

[0037] Specifically, the exterior wall waterproofing testing device provided in this embodiment includes a fixing component 4 and a spraying component. The fixing component 4 is used to fix it to the windowsill of the wall. Generally, the floor height of a residential building is about 3m. The waterproofing testing device in this embodiment is fixed and hung on the windowsill and connected to a telescopic rod assembly. For example, the top of the telescopic rod assembly is connected to the fixing component 4, and the spraying component is connected to the bottom of the telescopic rod assembly. Due to the telescopic characteristics of the telescopic rod assembly, the spraying component can be lowered and suspended in the area between the two windowsills of the exterior wall, and then spraying can be carried out directly using the spraying component.

[0038] Please refer to Figure 1 , Figure 2 and Figure 5The fixing component 4 provided in this embodiment includes a water tank 1, which is used to supply water to the spray assembly; preferably, a water inlet 11 is provided on the top of the water tank 1, so that when the water tank 1 is short of water, water can be directly added to the water tank 1 after opening the water inlet 11.

[0039] Furthermore, in this embodiment, the spray assembly includes a spray pipe 2, on which a plurality of nozzles 21 are provided. The nozzles 21 are used to spray water in the spray pipe 2. The nozzles 21 can be purchased components, and the specific structure is not limited.

[0040] The inlet of the spray pipe 2 is connected to one end of the water supply hose 22, and the other end of the water supply hose 22 is connected to the outlet pipe 12 on one side of the bottom of the water tank 1. A control valve 13 is provided on the outlet pipe 12, which is used to control the opening and closing of the outlet pipe 12.

[0041] It is understandable that, in order to achieve effective spraying of the spray system, a booster pump can be added to the spray system to increase the spray water pressure. The booster pump is a reasonable choice for those skilled in the art and is an optional purchased component, and no specific limitation is made.

[0042] Please continue to refer to Figures 1-4 In this embodiment of the utility model, the bottom of the water tank 1 is fixedly installed on the top plate 41 of the fixing component 4, which can improve the stability of the fixing component 4 when it is installed on the windowsill 51 by the weight of the water tank 1 itself.

[0043] A fixed seat 42 is fixedly provided on one side of the top plate 41, and a fixed clamping block 421 is fixedly connected to the fixed seat 42; correspondingly, a movable seat 43 is slidably provided on the other side of the top plate 41, and a movable clamping block 431 is fixedly connected to the movable seat 43.

[0044] Furthermore, the fixing component 4 in this embodiment also includes a threaded rod 45, one end of which is rotatably connected to the fixed seat 42, and the movable seat 43 is threadedly connected to the threaded rod 45 through the internal threaded through hole thereon; a limit block 44 is also fixedly provided at the end of the top plate 41, and the other end of the threaded rod 45 is rotatably connected to the limit block 44, which is used to provide stable support for the rotatable threaded rod 45.

[0045] Furthermore, the end of the threaded rod 45 is provided with an adjustment handle 451. In use, the supervisor and acceptance personnel can manually use the adjustment handle 451 to rotate the threaded rod 45.

[0046] In this embodiment, the wall 5 has a window sill 51. When in use, the supervisor can manually operate the adjustment handle 451 to drive the threaded rod 45 to rotate, which can drive the movable seat 43 to move so as to clamp and fix it on the window sill 51. When clamped and fixed, the window sill 51 is located between the fixed clamping block 421 and the movable clamping block 431.

[0047] Preferably, the top plate 41 has a side guide rail 411 integrally formed on its side; correspondingly, the movable seat 43 has a side track groove 432 that cooperates with the side guide rail 411, which is used to guide the movable seat 43 when it moves.

[0048] Please continue to refer to Figures 1-3 In this embodiment, the telescopic component provided includes an outer rod 3, which is a hollow structure. The telescopic component also includes an inner support rod 31. The outer rod 3 is coaxially sleeved on the inner support rod 31 to realize the telescopic adjustment of the overall length between the outer rod 3 and the inner support rod 31.

[0049] It is understood that those skilled in the art can design telescopic structures with more sections as needed, with specific limitations imposed.

[0050] Furthermore, the bottom end of the inner support rod 31 is fixedly connected to the mounting sleeve 33, and the spray pipe 2 is fixedly installed on the mounting sleeve 33. In this embodiment, the overall telescopic length between the inner support rod 31 and the outer support rod 3 is adjusted, specifically manually, to adjust the suspension height of the spray pipe 2 on the outer wall side.

[0051] Furthermore, both the outer rod 3 and the inner support rod 31 are provided with mounting through holes, and the outer rod 3 and the inner support rod 31 are connected and fixed by locking bolts 32 that mate with the mounting through holes.

[0052] Furthermore, such as Figure 2 and Figure 3 As shown, the top of the outer sleeve rod 3 is detachably fixed to the top plate 41;

[0053] Specifically, the top plate 41 has a notch, and a blocking block 413 is detachably fixed at the notch by means of bolt connection. An arc-shaped locking block 415 is fixedly connected to the blocking block 413. An arc-shaped fixing block 412 is also fixedly connected to the notch of the top plate 41. When the blocking block 413 is fixedly connected to the notch by fixing bolts 414, the arc-shaped locking block 415 and the arc-shaped fixing block 412 correspond to each other, and the two together form an installation channel. The outer sleeve rod 3 is in the state of passing through the installation channel. When it is necessary to fix the outer sleeve rod 3, the outer sleeve rod 3 is fixed to the arc-shaped fixing block 412 and the arc-shaped locking block 415 by bolts. This detachable connection method makes it easy to remove the outer sleeve rod 3 from the top plate 41, which is convenient for replacement and maintenance, and also convenient for separate storage after separation.

[0054] In summary, the waterproof testing device of this embodiment can lower the spray assembly and suspend it in the area between two windows on the exterior wall, and then directly use the spray assembly to spray water to simulate rainwater spraying onto the exterior wall. After spraying for a period of time, the supervisor can observe from inside whether the corresponding area is wetted, thereby judging the waterproof effect of the exterior wall.

[0055] The above solutions are merely illustrative examples of preferred embodiments, but are not limited thereto. When implementing this invention, appropriate substitutions and / or modifications can be made according to the user's needs.

[0056] The number of devices and processing scale described herein are for the purpose of simplifying the description of this utility model. Applications, modifications, and variations of this utility model will be readily apparent to those skilled in the art.
