A type of double-sided support hanger for air-raid shelter pipes

Abstract

This utility model discloses a double-sided support hanger for air-raid shelter ducts, comprising horizontal mounting frames disposed at the top and bottom of a rectangular duct. One of the horizontal mounting frames has two symmetrical diagonal reinforcing frames at its top. A longitudinal mounting rod is threaded through the top of each of the two diagonal reinforcing frames, and multiple nuts are threaded onto the surface of the longitudinal mounting rod. This utility model achieves double-sided support for the air duct using a triangular support structure, preventing deformation of the reinforcing rods after prolonged use and improving the stability of the air duct during operation. The two diagonal reinforcing frames are fixed to the top of the horizontal mounting frames. Two strip-shaped pieces are then inserted into the inner cavities of the strip-shaped holes on the surfaces of the diagonal reinforcing frames and the fixed frames, respectively. Rotating the strip-shaped pieces 90 degrees and then rotating the threaded torsion ring allows them to engage with the diagonal reinforcing frames or the fixed frames. By rotating the threaded rod and adjusting the length of the support rod and the threaded rod, the double-sided support hanger for the air duct can be reinforced, preventing deformation of the reinforcing rods after prolonged use and improving the stability of the air duct during operation.

Description

Technical Field

[0001] This utility model belongs to the field of air duct installation technology, and in particular relates to a double-sided support hanger for civil defense air ducts. Background Technology

[0002] Duct double-sided support hangers are devices used to fix and support duct systems. They are mainly composed of horizontal support members, longitudinal support members, channel steel bases, seismic connectors, anchor bolts, etc. The horizontal support members are located on the sides of the duct system and are fixed to the building structure by connection. The longitudinal support members pass vertically through the duct system and connect between the upper and lower horizontal support members to form a stable frame structure. The seismic performance of the duct system is enhanced by the reasonable arrangement of horizontal and longitudinal support members.

[0003] After the installation of the double-sided support hanger for air ducts is completed, in order to improve the stability of the air ducts, reinforcement rods are usually added to both sides of the double-sided support hanger. However, the reinforcement rods will deform after long-term use, making it difficult to guarantee the stability of the support. Therefore, a double-sided support hanger for air ducts in civil defense is needed. The double-sided support hanger for air ducts can be reinforced by a triangular support structure to prevent the reinforcement rods from deforming after long-term use and improve the stability of the air duct during use. Utility Model Content

[0004] The purpose of this utility model is to provide a double-sided support hanger for air defense ducts, which can be reinforced by a triangular support structure to prevent deformation of the reinforcement rods after long-term use, thereby improving the stability of the air duct during use and solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A double-sided support hanger for a civil defense air duct, comprising a transverse mounting frame set at the top and bottom of a rectangular tube, wherein the top of one of the transverse mounting frames is provided with two symmetrical oblique reinforcing frames, and a longitudinal mounting rod is provided through the top of each of the two oblique reinforcing frames. The surface of the longitudinal mounting rod is threaded with multiple nuts, and the bottom of the longitudinal mounting rod is provided through the oblique reinforcing frame and the two transverse mounting frames. The surface of each of the two longitudinal mounting rods is fitted with a fixing frame, and a support rod is provided above the oblique reinforcing frame. The inner cavity of the support rod is threaded with a threaded rod, and a connecting component is provided on the opposite side of the support rod and the threaded rod.

[0006] Preferably, the connecting assembly includes a connector fixedly connected to the surfaces of the support rod and the threaded rod, a connecting rod extending through the surface of the connector, a fixing torsion block fixedly connected to one end of the connecting rod, a fixing head fixedly connected to the surface of the connecting rod, a strip fixedly connected to the other end of the connecting rod, and a threaded torsion ring threadedly connected to the surface of the connecting rod.

[0007] Preferably, limiting members are provided on both sides of the rectangular tube, and a bolt is provided through the top of the limiting member. The bolt passes through the limiting member and the transverse mounting bracket and is threaded with a nut.

[0008] Preferably, protective heads are provided at both ends of the transverse mounting bracket, and the protective heads are adapted to the two ends of the transverse mounting bracket.

[0009] Preferably, the surfaces of the inclined reinforcement frame and the fixing frame are provided with multiple identical strip-shaped holes, and the strip-shaped pieces are adapted to the strip-shaped holes.

[0010] The beneficial effects of this utility model are: 1. This utility model fixes two inclined reinforcing frames to the top of the horizontal mounting frame, and then inserts two strip-shaped pieces into the inner cavities of the strip-shaped holes on the surface of the inclined reinforcing frame and the fixed frame respectively. The strip-shaped pieces are rotated 90 degrees, and then the threaded torsion ring is rotated to make the threaded torsion ring fit with the inclined reinforcing frame or the fixed frame. The threaded rod is rotated to adjust the length of the support rod and the threaded rod. This allows the double-sided support hanger of the air duct to be reinforced through the triangular support structure, avoiding deformation of the reinforcing rod after long-term use and improving the stability of the air duct during use. 2. This utility model uses limiting components. By placing two limiting components on both sides of the rectangular tube, the bottom of the limiting components is made to fit against one of the horizontal mounting brackets. Then, bolts pass through the limiting components and the horizontal mounting brackets and are threaded to connect the nuts. This allows the limiting components to limit the rectangular tube, preventing the rectangular tube from sliding between the two horizontal mounting brackets and improving the stability of the rectangular tube.

It includes transverse mounting brackets 2 disposed at the top and bottom of a rectangular tube 1. Limiting members 9 are provided on both sides of the rectangular tube 1. Bolts are threaded through the top of each limiting member 9, passing through both the limiting member 9 and the transverse mounting bracket 2, and are connected to a nut by threads. By placing the two limiting members 9 on both sides of the rectangular tube 1, with the bottom of each limiting member 9 abutting against one of the transverse mounting brackets 2, and the bolts threaded through the limiting member 9 and the transverse mounting bracket 2, the limiting members 9 can limit the rectangular tube 1, preventing it from sliding between the two transverse mounting brackets 2 and improving the stability of the rectangular tube 1. Two symmetrical diagonal reinforcing brackets 3 are provided at the top of one of the transverse mounting brackets 2. Each of the longitudinal mounting rods 4 is threaded through, and multiple nuts are threaded onto the surface of the longitudinal mounting rod 4. The bottom of the longitudinal mounting rod 4 is threaded through the oblique reinforcing frame 3 and two transverse mounting frames 2. Fixing frames 5 are fitted onto the surface of each of the two longitudinal mounting rods 4. A support rod 6 is provided above the oblique reinforcing frame 3. A threaded rod 7 is threaded onto the inner cavity of the support rod 6. A connecting assembly 8 is provided on the opposite side of the support rod 6 and the threaded rod 7. The connecting assembly 8 includes a connector 81 fixedly connected to the surface of the support rod 6 and the threaded rod 7. A connecting rod 82 is threaded through the surface of the connector 81. A fixing torsion block 83 is fixedly connected to one end of the connecting rod 82. A fixing head 84 is fixedly connected to the surface of the connecting rod 82. A strip 85 is fixedly connected to the other end of the connecting rod 82. A threaded torsion ring 86 is threaded onto the surface of the connecting rod 82.

[0015] Example 2: Figure 1-4This invention illustrates a dual-sided support hanger for a civil defense ventilation duct according to an embodiment of the present invention. It includes transverse mounting brackets 2 disposed at the top and bottom of a rectangular tube 1. Protective heads 10 are provided at both ends of the transverse mounting brackets 2, and the protective heads 10 are adapted to the ends of the transverse mounting brackets 2. Two symmetrical oblique reinforcing brackets 3 are provided at the top of one of the transverse mounting brackets 2. Multiple identical strip-shaped holes are opened on the surfaces of the oblique reinforcing brackets 3 and the fixing brackets 5. Strip-shaped pieces 85 are adapted to the strip-shaped holes. A longitudinal mounting rod 4 is provided through the top of each of the two oblique reinforcing brackets 3. Multiple nuts are threaded onto the surface of the longitudinal mounting rod 4. The bottom of the longitudinal mounting rod 4 passes through the oblique reinforcing bracket 3 and the two transverse mounting brackets 2. Fixing brackets 5 are fitted onto the surfaces of both longitudinal mounting rods 4. A support rod 6 is provided above the oblique reinforcing bracket 3. A threaded rod 7 is threaded into the inner cavity of the support rod 6. Connecting components 8 are provided on the opposite sides of the support rod 6 and the threaded rod 7.

[0016] Working principle: When using this utility model, the user places two horizontal mounting brackets 2 on the top and bottom of the rectangular tube 1 respectively, and then places two diagonal reinforcing brackets 3 on top of one of the horizontal mounting brackets 2, so that the longitudinal mounting rod 4 passes through the diagonal reinforcing bracket 3 and the two horizontal mounting brackets 2. The nut on the surface of the longitudinal mounting rod 4 is rotated to make it fit against the top of the diagonal reinforcing bracket 3 and the bottom of one of the horizontal mounting brackets 2, thus fixing the horizontal mounting bracket 2 and the diagonal reinforcing bracket 3. Then, the strip 85 at one end of the support rod 6 and the threaded rod 7 are respectively inserted into the diagonal reinforcing bracket. The inner cavity of the strip-shaped hole on the surface of frame 3 and fixed frame 5 is used to rotate the strip-shaped piece 85 by 90 degrees. Then, the threaded torsion ring 86 is rotated to make the threaded torsion ring 86 and the connecting rod 82 move together, so that the threaded torsion ring 86 is in contact with the inclined reinforcement frame 3 or fixed frame 5. The threaded rod 7 is rotated to enter the inner cavity of the support rod 6. The length of the support rod 6 and the threaded rod 7 is adjusted. After the adjustment is completed, the inclined reinforcement frame 3, fixed frame 5, support rod 6 and threaded rod 7 form a triangle for support, which prevents the reinforcement rod from deforming after long-term use and improves the stability of the air duct during use.

[0017] In summary, this double-sided support hanger for the ductwork reinforces the duct by fixing two oblique reinforcing brackets 3 to the top of the horizontal mounting bracket 2, inserting two strip-shaped pieces 85 into the inner cavities of the strip-shaped holes on the surfaces of the oblique reinforcing brackets 3 and the fixing bracket 5 respectively, rotating the strip-shaped pieces 85 ninety degrees, and then rotating the threaded torsion ring 86 to make the threaded torsion ring 86 fit with the oblique reinforcing bracket 3 or the fixing bracket 5, and rotating the threaded rod 7 to adjust the length of the support rod 6 and the threaded rod 7. This allows the double-sided support hanger for the ductwork to be reinforced through a triangular support structure, preventing deformation of the reinforcing rod after long-term use and improving the stability of the ductwork during use.
