Description

Technical Field

[0001] The invention relates to the technical field of equipment hoisting, in particular to a heavy equipment bracket with pre-embedded hanging parts. Background Art

[0002] In building installation projects, specific equipment and pipelines need to be installed at the top. Usually, holes are drilled in the floor and expansion screws are driven in, and then connected by installing hangers and bolts. However, this structure has limited force, especially for the installation of equipment with a certain weight. At the same time, the installed equipment is prone to falling off due to shaking, the opening of holes in the concrete floor destroys the floor structure, dust pollutes the environment during the construction process, and it is difficult to ensure the verticality of the components installed later. Insufficient verticality can easily cause shaking and falling off.

[0003] In the prior art, a Chinese patent document with publication number: CN203270805U discloses a pre-embedded hanger device, in which the screw rod, expansion tube and nut are cast in concrete together during construction. In this solution, since the screw rod is too long, its verticality cannot be guaranteed during construction. Secondly, the screw rod that is installed incorrectly needs to be cut off, and the ceiling strength requirement cannot be met when installing large heavy equipment. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a heavy equipment bracket with embedded hanging parts, which solves the problem that the existing embedded hanging parts need to be punched when arranged, making it difficult to ensure the verticality of the hanging parts. At the same time, since the hanging parts are independent of each other, the overall tensile strength and load capacity of the hanging parts need to be improved.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A heavy equipment support with embedded hanging parts comprises a floor slab formed by casting between concrete formworks, a fixing frame is arranged in the inner cavity of the floor slab, a reinforcing nut is fixedly connected to the fixing frame, a hanging rod is threadedly connected to the lower part of the reinforcing nut, an equipment and air duct fixing plate is fixedly arranged at the lower part of the hanging rod, and an air duct is installed on the equipment and air duct fixing plate.

[0009] Preferably, the fixing frame is fixedly connected to the top of the reinforcing nut by welding, and the fixing frame and the reinforcing nut are cast together in a concrete formwork to form a floor slab after solidification.

[0010] Preferably, before pouring concrete, the lower thread of the reinforcing nut is connected with a protective bolt, and the protective bolt passes through the concrete formwork. After the floor slab is formed, the concrete formwork and the protective bolt are removed.

[0011] Preferably, a plurality of anti-loosening nuts are provided on the hanger rod, and the anti-loosening nuts are pressed against the reinforcing nuts. The anti-loosening nuts are arranged on the upper and lower sides of the hanger rod located at the equipment and the air duct fixing plate.

[0012] Preferably, a plurality of reinforcing ribs are evenly arranged on the circumferential surface of the upper portion of the reinforcing nut.

[0013] (III) Beneficial effects

[0014] The present invention has the following beneficial effects:

[0015] The heavy equipment bracket of the embedded hanging parts improves the tensile strength and load capacity of the reinforcing nuts by forming the reinforcing nuts and the fixing frame into a whole and pouring them into the concrete, avoiding the need to drill holes in the floor slabs and beams to install hanging rods or expansion bolts in the later construction, which not only destroys the overall strength of the floor slabs and beams, but also pollutes the environment with dust during the construction process, and it is difficult to ensure the verticality of the components installed in the later stage, and insufficient verticality can easily cause shaking and falling off. At the same time, the embedded hanging parts provide a new method for the installation of heavy equipment and pipelines, which is particularly suitable for the concept of BIM design, and all equipment and pipelines are arranged in the three-dimensional model in the construction drawing stage.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1 The present invention provides a technical solution: a heavy equipment support with embedded hanging parts, comprising a floor slab 1 formed by casting between concrete formworks 8, a fixing frame 2 is arranged in the inner cavity of the floor slab 1, a reinforcing nut 3 is fixedly connected to the fixing frame 2, a hanging rod 4 is threadedly connected to the lower part of the reinforcing nut 3, an equipment and air duct fixing plate 6 is fixedly arranged at the lower part of the hanging rod 4, and an air duct 5 is installed on the equipment and air duct fixing plate 6.

[0023] The present invention improves the tensile strength and load capacity of the reinforcing nut 3 by forming the reinforcing nut 3 and the fixing frame 2 into a whole and casting them together in the concrete, and avoids drilling holes on the floor slab 1 and the beam to install the hanger 4 or expansion bolts in the later construction, which not only destroys the overall strength of the floor slab 1 and the beam, but also pollutes the environment with dust during the construction process, and it is difficult to ensure the verticality of the components installed in the later stage, and the lack of verticality easily causes shaking and falling off. At the same time, the embedded hanging parts provide a new method for the installation of heavy equipment and pipelines, which is particularly suitable for the concept of BIM design, and all equipment and pipelines are arranged in the three-dimensional model in the construction drawing stage.

[0024] Reference Figure 1 and 2 As shown, during construction, the wooden formwork of the beam and the floor slab 1 is first made to complete the binding of the steel bars of the beam and the floor slab 1. According to the position of the equipment in the drawing, a circular hole for placing the reinforcing nut 3 is opened on the wooden formwork, and the reinforcing nut 3 is placed on the inner side of the later concrete casting formwork 8, and the protective bolt 7 is placed on the outer side of the circular hole of the later concrete casting formwork 8. The reinforcing nut 3 is tightened by the protective bolt 7 to fix it on the wooden formwork. A fixing frame 2 is placed on the inner side of the later concrete casting formwork 8, so that the fixing frame 2 forms a whole with four adjacent reinforcing nuts 3 by welding. Concrete is poured, and the reinforcing nut 3 and the fixing frame 2 are poured together inside the concrete. After the concrete solidifies and meets the design requirements, the concrete formwork 8 and the protective bolt 7 are removed, and the hanging is installed at the position where the protective bolt 7 was originally placed. After the hanger 4 is in place, the loosening nut is tightened to prevent the hanger 4 from loosening due to shaking. The equipment and the air duct fixing plate 6 are installed at the bottom of the four hangers 4, and fixed to the hanger 4 with nuts. After checking the horizontality and installation position of all equipment and the air duct fixing plate 6, install the equipment and pipelines on the equipment and the air duct fixing plate 6.

[0025] Reference Figure 2 and3 As shown, in this embodiment, the fixing frame 2 is fixedly connected to the top of the reinforcing nut 3 by welding, and the fixing frame 2 and the reinforcing nut 3 are cast together in the concrete formwork 8, and the floor 1 is formed after solidification. By forming the reinforcing nut 3 and the fixing frame 2 into a whole and casting them together in the concrete, the tensile strength and load capacity of the reinforcing nut 3 are improved, and it is avoided that holes are opened on the floor slab 1 and the beam to install the hanger rod 4 or expansion bolts in the later construction, which not only destroys the overall strength of the floor slab 1 and the beam, but also pollutes the environment with dust during the construction process, and it is difficult to ensure the verticality of the components installed in the later stage, and the lack of verticality easily causes shaking and falling off.

[0026] Reference Figure 3 As shown, in this embodiment, before pouring concrete, the lower thread of the reinforcing nut 3 is connected with a protective bolt 7, and the protective bolt 7 penetrates the concrete formwork 8. After the floor slab 1 is formed, the concrete formwork 8 and the protective bolt 7 are removed. By setting the protective bolt 7, when pouring the floor slab 1, it is possible to effectively prevent the concrete from clogging the internal thread at the lower part of the reinforcing nut 3, thereby affecting the normal installation of the reinforcing nut 3 and the subsequent hanger 4.

[0027] Reference Figure 4 As shown, in this embodiment, a plurality of anti-loosening nuts 9 are arranged on the suspension rod 4, and the anti-loosening nuts 9 are pressed against the reinforcing nuts 3. Anti-loosening nuts 9 are arranged on the upper and lower sides of the suspension rod 4 located between the equipment and the air duct fixing plate 6. The anti-loosening nuts 9 can effectively ensure the stability of the installation between the suspension rod 4 and the reinforcing nuts 3, and between the suspension rod 4 and the equipment and the air duct fixing plate 6, and prevent the later loosening after assembly, which affects the stability of the overall hoisting.

[0028] Reference Figure 4 As shown, in this embodiment, a plurality of reinforcing ribs 31 are evenly arranged on the circumferential surface of the upper part of the reinforcing nut 3. The reinforcing ribs 31 can share the force exerted on the main part of the reinforcing nut 3, thereby ensuring the bearing capacity of the entire hanging part.
