Description

Technical Field

[0001] The utility model belongs to the technical field of building test devices, in particular to a watertightness test device for bending and local pressure-bearing components after deformation. Background Art

[0002] In the construction industry, waterproof performance is an important indicator for evaluating the quality of a roofing system. As common building roofing or facade materials, metal roofing systems or metal curtain wall systems require watertightness testing, which is particularly important.

[0003] Current national standards require watertightness testing for metal roofing and metal curtain wall systems. However, metal roof panels may deform during installation and implementation, and watertightness cannot be guaranteed after deformation. Therefore, watertightness testing is required for deformed metal roof panels.

[0004] Traditionally, deformation performance and waterproof performance tests are conducted separately. Often, a test component undergoes a deformation performance test before a watertightness test. If watertightness tests are conducted under multiple deformation displacements, multiple test pieces need to be used for separate tests, which is very expensive. Therefore, it is necessary to invent a device that can perform deformation performance tests and watertightness tests simultaneously. Summary of the Invention

[0005] The utility model provides a watertightness test device for bending and local pressure-bearing components after deformation, so as to solve the problem that traditional test devices cannot perform deformation performance tests and watertightness tests simultaneously.

The support column is used to position the spray system above the test structure. The water pipe is arranged along the support beam, and the spray head is fixed to the support beam.

[0011] In some embodiments of the present application, the nozzle is movable in a horizontal position. The nozzle position is adjusted as needed to spray water at a detection location. The detection location is usually a location prone to water leakage, such as a joint in a roof panel.

[0012] In some embodiments of the present application, there are multiple nozzles. By providing multiple nozzles, watertightness tests can be performed on multiple detection locations at the same time.

[0013] In some embodiments of the present application, the spray head includes a valve, a pressure gauge, and a pressure nozzle; the water pressure of the spray head is adjusted by the valve and the pressure gauge; and the water flow is controlled by the pressure gauge and the valve.

[0023] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figure 1 and Figure 2As shown, a watertightness test device for a bending or partially compressive member after deformation includes: a test bench 100, a test member 200, a loading system 300, a spraying system 400, a displacement testing system 500 and a data acquisition system 600; the test member 200 is placed on the upper side of the test bench 100, the loading system 300 provides a vertical loading force to the test member 200, the displacement testing system 500 tests the vertical displacement of the test member 200, and the data acquisition system 600 collects data from the loading system 300 and the displacement testing system 500 in real time; the spraying system 400 includes a water storage device 410, a water pump 420, a water pipe 440, and a nozzle 450. The spraying system 400 is placed on the upper side of the test member 200, and the spraying system 400 sprays water to the test member 200 after deformation due to the vertical loading force.

[0026] The loading system 300 can be a jack or an actuator. The loading system 300 applies a vertical load to the test member 200, causing the test member 200 to deform at the loading point. The vertical displacement of the loading point is monitored by the displacement testing system 500 (e.g., a displacement meter). The data acquisition system 600 collects data from the loading system 300 and the displacement testing system 500 in real time. Under multiple displacement test conditions, the deformed test member 200 is sprayed with water by the spraying system 400 to measure the watertightness of the test member 200 under different displacement conditions. For example, the loading system 300 can be used to sequentially force a metal roof panel or metal curtain wall panel to a corresponding deformation level, such as 10 mm, 20 mm, 30 mm, 40 mm, and 50 mm. At each deformation level, the spraying system 400 sprays water to perform a watertightness test, and so on, until the metal roof panel deforms or leaks, thereby evaluating the watertightness of the test member 200 under different deformation and displacement conditions. The test member 200 includes a support column for placing the test member on the upper side of the test bench 100 .

[0027] The test component 200 is a metal roof panel or a metal curtain wall panel.

[0028] The spray system 400 also includes a support column 470 and a support beam 460, which are arranged in a vertical direction. The support column 470 is used to place the spray system 400 on the upper side of the test structure 200. The water pipe 440 is arranged along the support beam 460, and the spray head 450 is fixed to the support beam 460.

[0029] The nozzle 450 is movable in a horizontal position. The position of the nozzle is adjusted as needed to spray water at the detection location. The detection location is usually a location prone to water leakage, such as a joint of a roof panel.

[0030] There are multiple nozzles 450. By providing multiple nozzles 450, watertightness tests can be performed on multiple detection positions at the same time.

[0031] like Figure 3 As shown, the nozzle 450 includes a valve 451, a pressure gauge 452 and a pressure nozzle 453. The water pressure of the nozzle 450 is adjusted by the valve 451 and the pressure gauge 452. The water flow is controlled by the pressure gauge 452 and the valve 451.

[0032] The spray system 400 further includes a drainage pump 430. The drainage pump 430 pumps water at the loading point after deformation to the water storage device 410, thereby realizing water recycling.

[0033] The water pipe 440 is made of metal, plastic-coated metal or plastic.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
