Description

Technical Field

[0001] This utility model relates to a hoisting and connection structure for ventilation ducts in prefabricated buildings, belonging to the field of ventilation duct installation technology. Background Technology

[0002] Ventilation ducts are metal or non-metal pipes used in ventilation and air conditioning systems for industrial and civil buildings. They are mainly used to transport air and also to reduce the concentration of harmful gases.

[0003] Patent document CN202420542336.X discloses a ventilation duct connection structure. It includes a first ventilation duct and a second ventilation duct. One end of the first ventilation duct is connected to a first connecting flange via fastening bolts, and one end of the second ventilation duct is connected to a second connecting flange via fastening bolts. Two mirror-shaped positioning posts are fixedly connected to the surface of the first connecting flange, each positioning post having a slot at one end. The second connecting flange has two mirror-shaped positioning grooves corresponding to the positioning posts inside, and two mirror-shaped mounting brackets corresponding to the positioning grooves are fixedly connected to the surface of the second connecting flange.

[0004] While the aforementioned patents can achieve the function of connecting ventilation ducts, the current technology is not comprehensive and has the following drawbacks: 1. Conventional supports require additional anti-sway hangers to suppress duct swaying, which increases structural complexity and installation costs. 2. Existing hangers mostly rely on welding or bolt fixing, and height and spacing adjustments require disassembly and reassembly, making it difficult to adapt to the needs of different pipe diameters or installation environments.

[0005] To solve one of the above problems, there is an urgent need for a hoisting and connection structure for ventilation ducts in prefabricated buildings. Utility Model Content

[0006] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to use the first and second cross braces to support the rectangular ventilation duct, and use the positioning columns A and B to abut against both sides of the rectangular ventilation duct to fix the ventilation duct more securely without the need for additional anti-sway hangers. The gap between the lower support crossbar assembly and the lower support crossbar assembly is adjustable, and the ventilation duct hoisting efficiency is higher. Therefore, a hoisting connection structure for ventilation ducts in prefabricated buildings is provided.

[0007] The prefabricated building ventilation duct hoisting and connection structure of this utility model includes a vertically arranged hanger A and a hanger B, with a preset gap between the hangers A and B. The structure is characterized by: a hanger top connecting seat A vertically installed on the top of hanger A, and a hanger top connecting seat B vertically installed on the top of hanger B; a lower support crossbar assembly and an upper positioning crossbar assembly are detachably installed between hangers A and hanger B, spaced apart; the gap between the lower support crossbar assemblies is adjustable; and hangers A, hanger B, the lower support crossbar assembly, and the upper positioning crossbar assembly form a limiting ring for the rectangular ventilation duct to pass through and for restricting the degrees of freedom of the rectangular ventilation duct.

[0008] This hoisting connection structure uses hanger A, hanger B, lower support crossbar assembly, and upper positioning crossbar assembly to form a limiting ring for the rectangular ventilation duct to pass through and to restrict the degree of freedom of the rectangular ventilation duct. The first and second crossbars support the rectangular ventilation duct, and the positioning columns A and B abut against the two sides of the rectangular ventilation duct, respectively, making the ventilation duct firmly fixed without the need for additional anti-sway hangers. The gap between the lower support crossbar assembly and the lower support crossbar assembly is adjustable, making the hoisting efficiency of the ventilation duct higher.

[0009] Preferably, the hanger A is a long strip plate structure with an elongated hole A along its length, and the hanger B is a long strip plate structure with an elongated hole B along its length. This design ensures reliable connection and strong applicability.

Two sets of positioning posts A are detachably installed on the upper part of the crossbar connecting frame A, and two sets of positioning posts B are detachably installed on the upper part of the crossbar connecting frame B. The crossbar connecting frame A is an X-shaped frame, and the four vertices of the X-shaped frame have connecting plates A, B, C, and D respectively. Connecting plates A and B are respectively connected to corresponding positioning posts A via corresponding upper connecting bolts A, and connecting plates C and D are respectively connected to corresponding lower connecting bolts B via corresponding lower connecting bolts A. Connecting bolt A is connected to the first and second cross braces. Both the upper and lower connecting bolts A pass through the elongated hole A. The crossbar connecting frame B has the same structure as the crossbar connecting frame A, and is also an X-shaped frame. The four vertices of the X-shaped frame have a first connecting plate, a second connecting plate, a third connecting plate, and a fourth connecting plate, respectively. The first and second connecting plates are connected to the corresponding positioning posts B by corresponding upper connecting bolts B. The third and fourth connecting plates are connected to the first and second cross braces by corresponding lower connecting bolts B, respectively. Both the upper and lower connecting bolts B pass through the elongated hole B. The first and second cross braces are used to support the rectangular ventilation duct. The positioning posts A and B abut against both sides of the rectangular ventilation duct.

[0012] First, install hanger A and hanger B, then install the second cross brace and the upper positioning crossbar assembly. The first cross brace and the first cross brace can be adjusted along the length of hanger A and hanger B. After adjustment, tighten them with the corresponding connecting bolts.

[0013] The installation process of the lower support crossbar assembly is as follows: place the first crossbar and the second crossbar below the ventilation duct, then use the corresponding connecting bolts to connect the first crossbar, the second crossbar and the corresponding positioning column A, and finally use the corresponding connecting bolts to connect the first crossbar, the second crossbar and the corresponding positioning column B. This completes the connection between the lower support crossbar assembly and the hangers A and B. The lower support crossbar assembly serves to support and limit the ventilation duct.

[0014] The installation steps for the upper positioning crossbar assembly and the lower supporting crossbar assembly are basically the same.

[0015] Preferably, the upper positioning crossbar assembly and the lower supporting crossbar assembly have the same structure but are arranged symmetrically.

[0016] Preferably, the top connecting seat A of the hanger includes a frame A perpendicularly connected to the hanger A, a reinforcing rib A is provided between the frame A and the hanger A, and the frame A has ceiling connecting bolts A. This facilitates the connection of the hanger A to the ceiling of the prefabricated building.
