Description

Technical Field

[0001] This utility model belongs to the field of building construction and is a support device for the construction of direct-buried distribution boxes in concrete in building electrical engineering. It can quickly realize the accurate positioning and pre-embedding of electrical distribution boxes in building installation. It is reusable, lightweight and convenient, and has a good forming effect. Background Technology

[0002] Currently, during the pre-embedded construction of electrical distribution boxes in building installation engineering, common quality problems such as bending, deformation, and blockage of electrical distribution boxes are easily caused after the concrete is poured. These problems affect the size and forming effect of the electrical conduit and the distribution box, junction box, etc. during the later installation.

[0003] Traditional building electrical installation projects have the following drawbacks in the pre-embedded construction of distribution boxes: The outer shell of the distribution box (made from waste wood templates to the same scale) is directly buried in the concrete, and before burying, it is sealed with sawdust or other filler materials and tape. This method can cause misalignment and bending of the vertical pre-embedded electrical conduits after the concrete is poured, and the outer shell of the distribution box is prone to deformation. It wastes manpower and time, and directly affects the installation quality and appearance of the distribution box and junction box in the later stage. The severely deformed outer shell of the distribution box cannot be installed and needs to be removed, and it also causes secondary damage to the concrete structure. Summary of the Invention

[0004] To prevent common quality defects such as breakage, bending, and blockage in electrical distribution boxes installed after concrete pouring, this utility model provides a wedge-shaped assembly adjustable support device for reinforcement.

[0005] A wedge-shaped assembly adjustable support device is characterized in that it consists of a four-way connector, a straight connector, a transverse connector, a fixing nut, and an adjustable support frame; the four-way connectors are connected to each other through the transverse connector, the four-way connector is connected to one end of the straight connector, the other end of the straight connector is connected to the fixing nut, and the fixing nut is connected to the adjustable support frame.

[0006] The four-way connector is composed of hollow short steel pipes welded at a 90-degree angle. Each interface end is welded with an inwardly concave wedge-shaped circular structure, and the two inwardly concave wedge-shaped circular structures in the horizontal and vertical directions have the same orientation.

[0007] The straight connector is made of a hollow long steel pipe. One end has a solid cylindrical part of a certain length inside, and the center of the cylindrical part has a threaded through hole. The other end is welded with an outwardly convex wedge-shaped circular structure, which is used to connect with the four-way connector, which has an inwardly concave wedge-shaped circular structure at the end.

[0008] The transverse connector is made of hollow steel pipe, with an externally concave wedge-shaped circular structural component welded to each end, and the opening direction of the externally concave wedge-shaped circular structural components at both ends is consistent.

[0009] The adjustable support frame is welded to a threaded rod and a support circular plate. One end of the threaded rod is welded to the support circular plate, and the other end of the threaded rod is connected to the built-in threaded through hole of the straight connector.

[0010] The invention achieves support for the distribution box housing in both longitudinal and transverse directions by adjusting the size and position of the adjustable support frame 4 on the straight connector 2, and is fixed by the fixing nut 3, while appropriately meeting the reinforcement support requirements of distribution box housings 6 of different sizes.

[0011] It can be connected in equal intervals according to the external dimensions of the distribution box. By increasing the number of four-way connectors and horizontal connectors, and supplementing with an adjustable support frame and fixing nuts, the dimensions of the device can be adjusted in both longitudinal and transverse directions to meet the needs of pre-embedded distribution boxes of various specifications and models.

[0012] This invention is recyclable, reduces material costs, and solves problems such as deformation, bending, and blockage of the outer shell of existing pre-embedded electrical distribution boxes in concrete.

[0013] This invention enables rapid and precise positioning and reliable reinforcement of directly buried distribution boxes in building electrical engineering installations. Furthermore, the finished outer shell (holes) of the distribution box after removal exhibits a good aesthetic appearance, effectively preventing common quality defects such as breakage, bending, and blockage of the distribution box shell after concrete pouring. Compared to traditional methods, it has strong practicality and scalability, generating significant economic and social benefits. Attached Figure Description

[0021] Figure 1 As shown, a wedge-shaped assembly adjustable support device is characterized by comprising a four-way connector 1, a straight connector 2, a transverse connector 5, a fixing nut 3, and an adjustable support frame 4.

[0022] The four-way connector 1 is composed of hollow short steel pipes 1-1 welded at a 90-degree angle. Each interface end is welded with an inwardly concave wedge-shaped circular structure 1-2, and the openings of the two inwardly concave wedge-shaped circular structures 1-2 in the horizontal and vertical directions are aligned in the same direction. They are used to connect with the outwardly convex wedge-shaped circular structure 2-2 on the straight connector 2 and with the outwardly convex wedge-shaped circular structure 2-2 on the transverse connector 5.

[0023] The straight connector 2 is made of a hollow long steel pipe 2-1, with a solid cylindrical part 2-3 of a certain length built into one end, and a threaded through hole built into the center of the cylindrical part 2-3; the other end is welded with an outwardly convex wedge-shaped circular structure 2-2, which is used to connect with the four-way connector 1, which has an inwardly concave wedge-shaped circular structure 1-2 at the end.

[0024] The transverse connector 5 is made of hollow steel pipe 5-1, with an externally concave wedge-shaped circular structure 2-2 welded to each end. The opening directions of the externally concave wedge-shaped circular structure 2-2 at both ends are consistent, and it is used to connect with the four-way connector 1, which has an internally concave wedge-shaped circular structure 1-2 at the end.

[0025] The adjustable support frame 4 is formed by welding a threaded rod 4-1 to a support circular plate 4-2. One end of the threaded rod 4-1 is welded to the support circular plate 4-2, and the other end is connected to the built-in threaded through hole of the straight connector 2.

[0026] The concave wedge-shaped circular structure 1-2 is a cylindrical boss structure with the same diameter as the hollow short steel pipe 1-1. The two halves of the concave wedge-shaped circular structure are formed after the inscribed isosceles trapezoidal structure. The orientation, position and size of the two halves satisfy the clearance fit relationship with the convex wedge-shaped circular structure 2-2.

[0027] The convex wedge-shaped circular structural component 2-2 is a cylindrical boss structure with the same diameter as the hollow steel pipe 5-1. After circling four semi-circular structures, it forms an convex isosceles trapezoidal structure. Its orientation, position, and size satisfy the clearance fit relationship with the concave wedge-shaped circular structural component 1-2.

[0028] The specific implementation method of this utility model is as follows: Figure 1 , 6 As shown, the dimensions and spacing of this utility model are determined in advance based on the construction drawings and the size requirements of the distribution box shell provided by the supplier. The quantity of each component constituting this utility model is then determined and the utility model is manufactured. Before pouring concrete, this utility model is first assembled according to… Figure 1 After connection, the entire assembly is installed inside the distribution box shell (made from recycled wooden templates) 6. Reliable support for this invention is achieved within the distribution box shell by adjusting the size and position of the adjustable support frame 4 on the direct connector 2. Once the position is determined, it is tightened using fixing nuts 3, ensuring secure support on all four sides of the distribution box shell. The installed distribution box shell is then secured to the positions specified in the drawings using steel wire. After the concrete reaches its design strength, the invention is removed, completing the pre-embedded construction of the distribution box shell. The removed invention can then be recycled.
