Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated building construction, in particular to a slurry leakage prevention structure at joints of prefabricated buildings. Background Art

[0002] Prefabricated buildings have been widely promoted and applied. With the continuous expansion of urban residential construction, residential industrialization has become a key trend in the construction industry. As a key integral flexural member in prefabricated buildings, composite slabs play a crucial role in the development of residential industrialization.

[0003] Nowadays, prefabricated buildings are becoming more and more popular, among which prefabricated composite panels are particularly widely used. During the construction of prefabricated buildings, aluminum alloy templates are generally used for concrete formwork. The existing construction joint structure of prefabricated composite panels supported by aluminum alloy templates still has the problem of leakage at the joints between prefabricated composite panels and aluminum alloy templates during use. At the same time, the aluminum alloy templates used for the anti-leakage structure at the joints of prefabricated buildings are not easy to disassemble and adjust, and thus have insufficient applicability.

[0004] Therefore, it is necessary to design a slurry leakage prevention structure at the joints of prefabricated buildings to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a slurry leakage prevention structure at the joints of prefabricated buildings, so as to improve the slurry leakage prevention structure at the joints of prefabricated buildings by adding a flexible waterproof membrane buffer layer to avoid slurry leakage at the joints between prefabricated composite panels and aluminum alloy formworks. At the same time, a detachable and adjustable aluminum alloy formwork and a support system are used to adapt to the slurry leakage prevention construction at the joints of prefabricated buildings of different sizes and heights, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A slurry leakage prevention structure for the joints of prefabricated buildings includes a cast-in-place joint section and a prefabricated composite panel.

An aluminum film plate is provided at the bottom of the SBS waterproof membrane. Splicing seats are fixedly assembled on both sides of the aluminum film plate. The bottom end of the splicing seat is threadedly connected to an adjustment support rod.

[0008] As a preferred solution of the present invention, there are two prefabricated composite panels in total, and the cast-in-place section of the joint between the two prefabricated composite panels is 50 mm. A pressed groove with a width of 50 mm and a thickness of 4 mm is reserved at the bottom intersection of the cast-in-place sections of the prefabricated composite panels near the joint, and the size of the SBS waterproof membrane is matched and installed inside the pressed groove.

[0009] As a preferred solution of the present invention, the SBS waterproof membrane has a width of 50 mm and a thickness of 4 mm.

[0010] As a preferred solution of the present invention, strip connecting grooves are provided on both sides of the aluminum film plate, and a connecting bolt is installed inside the strip connecting groove on one side of the splicing seat, one end of the connecting bolt extends to the interior of the aluminum film plate and is sleeved with a locking nut, and multiple assembly holes are opened at the front and rear ends of the aluminum film plate.

[0011] As a preferred solution of the present invention, a threaded seat is installed at the inner top of the splicing seat, and the adjustment support rod includes an adjusting screw and a fixed sleeve, and the top of the adjusting screw is threadedly connected to the inner part of the threaded seat.

[0012] As a preferred solution of the present invention, a fixing seat is installed at the bottom end of the fixed sleeve, a locking sleeve is installed at the top of the fixed sleeve, the bottom end of the adjusting screw passes through the interior of the locking sleeve and is inserted into the interior of the fixed sleeve, and the outer movable sleeve of the adjusting screw is provided with a locking rotary sleeve connected to the locking sleeve.

[0013] Beneficial effect: Aiming at the problem that leakage of mortar at the joints between prefabricated composite panels and aluminum alloy formwork cannot be avoided in the prior art, and the aluminum alloy formwork and support system cannot be disassembled and adjusted to be suitable for the anti-leakage construction of prefabricated buildings of different sizes and heights, in the utility model, the pressure grooves provided on the prefabricated composite panels are matched with the SBS waterproof membranes provided, and the SBS waterproof membranes are supported by the aluminum membrane panels with adjustable support rods. A flexible waterproof membrane buffer layer is added between the prefabricated composite panels and the aluminum membrane panels to avoid hard connection, thereby avoiding joints. In order to solve the problem of slurry leakage, the connecting bolts set in the splicing seat are passed through the strip connecting grooves on the aluminum membrane plate and the support connection spacing is adjusted. Then, the locking bolts are used for assembly and connection. At the same time, the adjusting screw set in the support rod is adjusted to be combined with the threaded seat of the splicing seat. Subsequently, the length of the adjusting screw pulled out from the fixed sleeve is adjusted according to the support height requirement, and the adjusted screw is locked by the locking sleeve and the locking rotary sleeve, thereby realizing a detachable and adjustable aluminum alloy formwork and support system suitable for the anti-slurry construction at the joints of prefabricated buildings of different sizes and heights.
