Description

Technical Field

[0001] This utility model relates to the field of ALC exterior wall panel waterproof testing technology, and more specifically, it relates to a testing fixture for the waterproof performance of ALC exterior wall panels. Background Technology

[0002] Autoclaved aerated concrete (ALC) wall panels have been widely used in non-load-bearing parts of buildings in recent years due to their excellent properties such as lightweight, thermal insulation, sound insulation, and earthquake resistance. With technological advancements exploring their application in the external envelope of high-rise buildings, it is necessary to strengthen the waterproof performance testing of ALC wall panels to ensure the building's interior is protected from moisture damage and to prevent steel reinforcement corrosion and concrete corrosion. Therefore, conducting waterproof testing on ALC wall panels is of great significance for the promotion and application of this green building material.

[0003] Currently, there are no dedicated testing methods or supporting equipment for ALC waterproofing performance. Testing is mostly conducted by referring to existing standards and testing methods for building curtain walls, doors and windows, etc.

[0004] The waterproofing performance of ALC exterior wall panels focuses on the self-waterproofing of the wall panels themselves and the waterproofing of the wall panel joints. After the wall panels are spliced, it is necessary to simulate the on-site construction environment to realize the connection method of the wall panels to the building's load-bearing structure by external hanging or internal embedding. At the same time, it is also necessary to realize the connection between the test wall panels and the spraying equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a testing fixture for the waterproof performance of ALC exterior wall panels, and an auxiliary installation fixture that can install ALC exterior wall panels in two ways: external hanging and embedded installation.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a test fixture for the waterproof performance of ALC exterior wall panels, comprising: a spray test chamber, an inlay fixture, and an ALC exterior wall panel.

[0007] The inlay fixture has a rectangular frame structure with a splicing cavity in the middle. The inlay fixture is set at the test port position of the spray test box. The inlay fixture is fixed to the spray test box by a wooden template. At least one side of the contact surface between the splicing cavity and the ALC exterior wall panel is provided with a wedge.

[0008] Several of the aforementioned ALC exterior wall panels are assembled together and then embedded in the assembly cavity of the inlay fixture.

[0009] The spray test chamber, through the installation of fixtures, allows ALC exterior wall panels to be directly placed within the pressure spray distance. The installation of fixtures can completely simulate the actual post-construction effect, that is, by testing the ALC exterior wall panels after construction, the post-construction effect can be directly detected.

[0010] The present invention is further configured such that the inlay fixture includes a standard module in the shape of a strip that can be connected end to end and corner modules that are matched and fixed at right angles in pairs.

[0011] By dividing the inlay fixture into standard modules and corner modules, the effect of lengthening and widening can be achieved to cope with inlay splicing tests of different lengths and widths.

[0012] The present invention is further configured such that: the standard module is provided with corresponding oblique grooves on both sides of the contact surface with the ALC exterior wall panel, and flat pull holes for mutual extension and connection are provided in the oblique grooves.

[0013] The beveled slot design allows for easy connection of two adjacent standard modules.

[0014] The present invention is further configured such that: the corner module includes a horizontal segment and an oblique angle portion disposed at one end of the horizontal segment, and oblique grooves are provided on both sides of the horizontal segment away from the oblique angle portion and close to the contact surface between the corner module and the ALC exterior wall panel.

[0015] The beveled section effectively corresponds to the right-angled part of the ALC exterior wall panel, preventing water leakage and affecting test results in case the right-angled part cannot fit properly. The horizontal section connects to the standard module, reducing the complexity of the connection.

[0016] The present invention is further configured such that: a pull hole that completely penetrates the beveled portion is provided in the middle of the beveled portion, and at least one pull hole is provided on each beveled portion.

[0017] The design of the pull holes effectively tightens two adjacent beveled parts, resulting in a smaller seam and a more stable connection.

[0018] The present invention is further configured such that the pull holes between every two adjacent beveled portions are coaxially arranged.

[0019] Only when the tie holes between the two beveled sections are coaxial can the two adjacent corner modules be fixed together to form a right angle using a tie bolt.

[0020] In summary, this utility model has the following beneficial effects: the spray test box can directly place the ALC exterior wall panel within the pressure spray distance through the embedded fixture. The embedded fixture can completely simulate the effect after construction in the actual situation. That is, the effect after construction can be directly detected by testing the ALC exterior wall panel after construction. Attached Figure Description

[0037] Example

[0038] The waterproof performance of ALC exterior wall panels (3) focuses on the self-waterproofing of the wall panels themselves and the waterproofing of the wall panel joints. After the wall panels are spliced, it is necessary to simulate the on-site construction environment to realize the connection between the wall panels and the building load-bearing structure by external hanging or internal embedding. At the same time, it is also necessary to realize the connection between the test wall panels and the spraying equipment.

[0039] To address the above issues, a waterproof performance testing fixture for ALC exterior wall panels (3) was developed to solve the connection and fixing problems between wall panels and between wall panels and the test bench in the waterproof test of ALC exterior wall panels (3), as well as to simulate the situation.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, a waterproof performance testing fixture for an ALC exterior wall panel (3) includes: a spray test chamber, an inlay fixture (1), and an ALC exterior wall panel (3).

[0041] The inlay fixture (1) has a rectangular frame structure with a splicing cavity in the middle. The inlay fixture (1) is set at the test port position of the spray test box. The inlay fixture (1) and the spray test box are fixedly set by a wooden template. At least one side of the contact surface between the splicing cavity and the ALC outer wall panel (3) is provided with a wedge.

[0042] Several of the ALC exterior wall panels (3) are assembled together and then embedded in the assembly cavity of the inlay fixture (1).

[0043] like Figure 5 As shown, the inlay fixture (1) includes a standard module (11) that is strip-shaped and can be connected end to end, and corner modules (12) that are matched and fixed at right angles in pairs.

The horizontal section (121) is provided with beveled grooves (111) on both sides of the end away from the beveled portion (122) and close to the contact surface between the corner module (12) and the ALC exterior wall panel (3). The beveled portion (122) can effectively correspond to the right angle of the ALC exterior wall panel (3), preventing water leakage from affecting the test results in the case that the right angle cannot fit. The horizontal section (121) is connected to the standard module (11) to reduce the complexity of the connection.

[0047] The beveled portion (122) has a pull hole (123) that completely penetrates the beveled portion (122) in the middle, and each beveled portion (122) has at least one pull hole (123); the pull hole (123) can effectively tighten two adjacent beveled portions (122) so that the joint between them is smaller and the connection is more stable.

[0048] The pull holes (123) between each two adjacent beveled portions (122) are opened along the same axis; only when the pull holes (123) between the two beveled portions (122) are along the same axis can the two adjacent corner modules (12) be fixed to form a right angle by a pull bolt.

[0049] In this embodiment, in order to further achieve the waterproof effect, a stepped keyway is provided on the contact surface between the inlay tool (1) and the top surface of the ALC exterior wall panel (3). Before construction, an interface agent is applied to the keyway and the ALC exterior wall panel (3) to ensure the firm fixation of the sealant and adhesive.
