Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building construction, and in particular relates to a SPCS prefabricated wall component lower mouth plugging and shaping formwork. BACKGROUND

[0002] In recent years, with the vigorous development of building industrialization, the prefabricated building market is booming, and new prefabricated systems are constantly emerging. SPCS prefabricated wall is a modern building material, which is made of prefabricated plates and cement mixture. SPCS prefabricated wall has many advantages, including easy construction, time and cost saving, good seismic performance, etc. The main feature of SPCS prefabricated wall is that they can be completed in a short time, and there is no problem such as cracking or deformation in use. In addition, SPCS prefabricated wall also has good thermal insulation performance, which can improve the heat insulation performance of buildings. In short, SPCS prefabricated wall is a very practical and economical building material, which is widely used in various construction projects. After the SPCS wall is installed, there is a gap of 50mm in height between the root of the wall and the structure floor, which is used to observe the compactness of the concrete in the cavity after pouring.

[0003] However, due to the large gap reserved for the installation of SPCS wall, it is difficult to ensure the concrete forming quality of this part, and the construction difficulty is large. SUMMARY

[0004] Therefore, the application provides a SPCS prefabricated wall component lower mouth plugging and shaping formwork, which can solve the problem that it is difficult to ensure the concrete forming quality of this part due to the large gap reserved for the installation of SPCS wall, and the construction difficulty is large.

[0005] The application is implemented as follows:

[0006] The application provides a SPCS prefabricated wall component lower mouth plugging and shaping formwork, which comprises square steel and angle steel. The angle steel is in L-shaped structure, and the square steel and the angle steel are correspondingly arranged on both sides of the SPCS prefabricated wall to support and fix the SPCS prefabricated wall. A fixing screw is arranged between the square steel and the angle steel. The fixing screw comprises an outer screw and an inner screw. The inner part of the outer screw is provided with a forward thread, and the outer side of the inner screw is provided with a reverse thread. The forward thread and the reverse thread correspond to each other. The side surface of the outer screw is provided with a tapered surface, and the front end of the inner thread is provided with a sharp part. The sharp part passes through the tapered surface of the outer thread to fix the square steel and the angle steel. The square steel and the angle steel are provided with a plurality of reinforcing holes. The fixing screw passes through the reinforcing holes on the square steel and the angle steel to reinforce the square steel and the angle steel. There are a plurality of fixing screws.

[0007] The technical effects of the standardized template for sealing the bottom of a SPCS precast wall component provided by this invention are as follows: By setting the square steel and the angle steel, the bottom of the SPCS precast wall is reinforced. The shape of the square steel and the angle steel is the same as the installation position of the SPCS precast wall, which facilitates the rapid installation of the SPCS precast wall. By setting the fixing screws to support the square steel and the angle steel, the problem of difficulty in ensuring the concrete forming quality and construction difficulty in the area due to the large gap reserved for the installation of the SPCS wall can be solved.

[0008] Based on the above technical solution, the SPCS prefabricated wall component bottom sealing template of the present invention can be further improved as follows:

[0009] The inner screw has a fixing part and a connecting part. The fixing part is elongated, and the connecting part is wedge-shaped. The connecting part is hinged to the rear end of the tip by a compression spring. The diameter of the connecting part is smaller than the diameter of the outer screw. The length of the fixing part is greater than the length of the outer screw.

[0010] The beneficial effects of adopting the above-mentioned improved scheme are as follows: by setting external and internal threaded rods to support the square steel and the angle steel, the problem of difficulty in ensuring the concrete forming quality and construction difficulty in the SPCS wall installation due to the large gap reserved in the pre-installation is solved.

[0011] Furthermore, a large nut is provided at the position where the external threaded rod abuts against the square steel, and a fixing bolt is provided on the side of the large nut away from the external threaded rod. The fixing bolt is used to adjust the relative position of the large nut and the outer threads of the external threaded rod.

[0012] Furthermore, the method of using the standardized template for sealing the bottom of the SPCS precast wall component is as follows:

[0013] S10: Process the base layer of the lower wall and hoist the SPCS prefabricated wall to the top of the lower wall;

[0014] S20: Elevate the lower wall by using an alignment mechanism to align the lower wall with the corresponding position of the SPCS prefabricated wall, and fix a shim at the corresponding position of the lower wall with a height of 50mm.

[0015] S30: Fix the standardized template for sealing the bottom opening of the SPCS prefabricated wall component to both sides of the gasket;

[0016] S40: Concrete is poured in layers into the prefabricated formwork at the bottom of the SPCS precast wall component;

[0017] S50: Degas the concrete;

[0018] S60: After the concrete has solidified, its surface is polished and cured.

[0019] The specific steps for grinding and curing the surface of the concrete after it has solidified include:

[0020] Within 24 hours after the concrete is poured, water is sprayed onto the concrete multiple times to keep the surface of the mixed soil moist. The water spraying process is repeated 3 to 5 times a day for 7 to 10 days.

[0021] Furthermore, the specific steps for fixing the standardized template for sealing the lower opening of the SPCS precast wall component to both sides of the gasket are as follows:

[0022] The first step is to install square steel and angle steel on both sides of the gasket. The square steel is installed at the direct connection between the SPCS precast wall and the lower wall, and the angle steel is installed at the bend connection between the SPCS precast wall and the lower wall.

[0023] The second step involves the outer screw passing through the corresponding reinforcing holes on the square steel and the angle steel, and the inner screw being connected to the forward thread of the outer screw via a reverse thread.

[0024] Third, the outer screw and the inner screw are fixedly connected by a connecting part.

[0025] The beneficial effects of the above-mentioned improved scheme are as follows: By setting square steel and angle steel on both sides of the gasket, the square steel is set at the direct connection between the SPCS precast wall and the lower wall, and the angle steel is set at the bend connection between the SPCS precast wall and the lower wall; the external threaded rod passes through the corresponding reinforcement holes on the square steel and the angle steel, and the internal threaded rod is connected to the forward thread of the external threaded rod through a reverse thread; the external threaded rod and the internal threaded rod are fixedly connected through a connecting part, which can solve the problem that it is difficult to ensure the concrete forming quality and the construction difficulty is due to the large gap reserved for the installation of the SPCS wall.

[0026] Furthermore, the alignment mechanism includes an infrared emitting mechanism and an infrared receiving mechanism. The infrared emitting mechanism is located at the bottom connection position between the SPCS prefabricated wall and the lower wall, and the infrared receiving mechanism is located at the position where the lower wall connects to the SPCS prefabricated wall. The infrared emitting mechanism and the infrared receiving mechanism correspond to each other.

[0027] Furthermore, the specific steps for venting the concrete include:

[0028] The vibrator is attached to the concrete formwork, and the angle and position of the vibrator are adjusted as needed. During the concrete pouring process, the vibrator is used to perform directional vibration to lift air bubbles in the concrete from the flow area of ​​the concrete to the pouring surface and expel the air from the concrete.

[0029] Furthermore, the diameter of the tip is the same as the diameter of the external screw.

[0030] Furthermore, the spacing between the plurality of reinforcing holes on the square steel and the angle steel is 200mm, the diameter of the reinforcing holes is 20mm, and the height of the square steel and the angle steel is 100mm.

[0031] Furthermore, the square steel is made of aluminum alloy.

[0032] Compared with existing technologies, the beneficial effects of the standardized template for sealing the bottom of SPCS precast wall components provided by this invention are as follows: By setting the square steel and the angle steel, the bottom of the SPCS precast wall is reinforced. The shape of the square steel and the angle steel is the same as the installation position of the SPCS precast wall, which facilitates the rapid installation of the SPCS precast wall. By setting the fixing screws to support the square steel and the angle steel, the problem of difficulty in ensuring the concrete forming quality and construction difficulty in the area due to the large gap reserved for SPCS wall installation can be solved.
