Description

Technical Field

[0001] This utility model relates to the field of duct installation, and in particular to a duct support frame and duct support system on a wooden beam. Background Technology

[0002] In the process of renovating old buildings, we often encounter buildings with tiled roofs and wooden trusses as the supporting structure. During renovation, considering factors such as preserving the building's historical value, cost control, and structural safety, it is usually necessary to retain the original wooden trusses and tiled roof. However, as the building's functions expand or improve, it is often necessary to install ductwork to meet the operational needs of ventilation, air conditioning, and other systems.

[0003] Traditional duct installation involves suspending the duct onto a concrete roof using brackets. This method relies on the stability and space provided by the concrete roof. However, the existing timber truss-tile roof structure of older buildings differs significantly from the concrete roof structure in terms of load-bearing capacity and spatial layout. Therefore, traditional duct installation methods cannot be directly applied to these older structures. Thus, developing an installation solution that can achieve stable duct fixing based on timber trusses has become a pressing technical problem to be solved in the renovation and reconstruction of old buildings. Utility Model Content

[0004] The purpose of this invention is to overcome the problem that traditional duct installation methods in the prior art cannot be directly applied to old buildings with wooden truss-tile roof structures, and to provide a duct support frame and duct support system on wooden beams.

[0005] In a first aspect, the present invention provides a duct support frame on a wooden beam, comprising:

[0006] Two vertical poles are arranged side by side, and the bottoms of the two vertical poles are respectively used to connect to the wooden beam;

[0007] A crossbeam is arranged between two vertical rods, and both ends of the crossbeam are connected to the tops of the two vertical rods by a first spring. The top surface of the crossbeam is used to support the air duct.

[0008] A horizontal connecting rod, the two ends of which are respectively connected to the tops of the two vertical rods.

[0009] This invention provides a duct support frame on a wooden beam, with two vertical rods connected to the beam. A horizontal beam supports the duct and transfers the load of the duct to two first springs. Upon receiving the load from the horizontal beam, the two first springs further transfer the tensile load to the two vertical rods. The horizontal connecting rod strengthens the connection between the two vertical rods and, together with them, forms a portal frame structure, effectively improving the stability of the entire device. Simultaneously, the first springs have vibration absorption capabilities, absorbing the vibrations generated by the duct during operation, thereby reducing the adverse effects of duct vibration on the wooden beam.

[0010] This utility model provides a duct support frame on a wooden beam. Through the coordinated action of the crossbeam, the first spring, and the two vertical rods, the duct is reliably connected to the wooden beam, thereby solving the problem that traditional duct installation methods cannot be directly applied to old buildings with wooden truss-tile roof structures.

[0011] Preferably, both ends of the crossbeam are connected to the two vertical rods via second springs, and both second springs are horizontally arranged. In this design, because the second springs are horizontally arranged, when the crossbeam vibrates, the horizontally placed second springs can absorb the horizontal vibration energy of the crossbeam along its own axial direction. Since the vibration generated during the operation of the duct may be transmitted to the crossbeam, the reduction of the axial horizontal vibration of the crossbeam can effectively reduce the possibility of horizontal swaying of the duct due to vibration during operation.

[0012] The vertical rod and the wooden beam can be fixed by anchor bolts or clamps.

[0013] Preferably, each vertical rod is equipped with a first fixing member and a second fixing member. The bottom of the vertical rod is connected to the first fixing member. The first fixing member and the second fixing member are used to clamp the top and bottom surfaces of the wooden beam, respectively. The first fixing member and the second fixing member are connected by a threaded rod. In this design, the first fixing member and the second fixing member can firmly clamp the wooden beam. Simultaneously, since the bottom of the vertical rod is connected to the first fixing member, a stable connection between the vertical rod and the wooden beam is achieved. Compared with the riveting connection method, this design has significant advantages. Riveting connections require drilling holes in the wooden beam, which damages the original structural integrity of the wooden beam. This design uses a clamp-type connection, eliminating the need for drilling holes in the wooden beam and preventing structural damage. This better protects the wooden beam, reduces potential problems caused by structural damage, effectively improves the durability of the wooden beam, and extends its service life.

[0014] Preferably, a first pad and a second pad are respectively provided at the contact positions between the first and second fixing members and the wooden beam. In this design, the main function of the first and second pads is to effectively disperse the stress generated at the connection points during the connection process between the first and second fixing members and the wooden beam, preventing excessive stress concentration at a single point or small area. This stress dispersion significantly reduces damage to the wooden beam during the connection process, ensuring the structural integrity and performance of the wooden beam. The first and second pads can be made of various materials, such as rubber, polyethylene plastic, or cork, all of which possess good flexibility and cushioning properties, enabling better stress dispersion and protection of the wooden beam.

[0015] Preferably, both the first and second pads are made of natural rubber. Compared to polyethylene plastic, the rubber material has better elasticity and flexibility. Compared to corkboard, the natural rubber has better durability and can maintain stable performance over a longer period of time.

[0016] Both the first and second fasteners can be made of square steel pipe, channel steel, steel plate or angle steel.

[0017] Preferably, both the first fastener and the second fastener are made of steel plate or angle steel.

[0018] Preferably, two symmetrically arranged limiting members are provided on the crossbeam along its length. In this design, the two limiting members cooperate to clamp the duct between them, thereby effectively limiting the displacement of the duct in the lateral direction and fixing the duct in the lateral direction.

[0019] The connection between the limiting member and the crossbeam can be fixed or movable.

[0020] Preferably, the limiting member can move and be fixed along the length of the crossbeam. This design gives the limiting member more flexible lateral constraint on the duct. Specifically, this design can effectively avoid situations where the duct cannot be smoothly installed between the two limiting members due to deviations in installation dimensions. In addition, this design also allows the support frame to adapt to ducts with different lateral dimensions, significantly improving the applicability and versatility of the device.

[0021] The two vertical rods, the crossbeam, and the horizontal connecting rod can all be made of steel pipe, channel steel, I-beam, or angle steel.

[0022] Preferably, the two vertical rods, the crossbeam, and the horizontal connecting rod are all made of angle steel.

[0023] In a second aspect, the present invention provides a duct support system, comprising several duct support frames on wooden beams as described in the first aspect, wherein the duct support frames are arranged sequentially on the wooden beams arranged side by side.

[0024] This utility model provides a duct support system that reliably connects the duct to the wooden beam through the coordinated action of the crossbeam, the first spring, and the two vertical rods in each duct support frame. This solves the problem that traditional duct installation methods cannot be directly applied to old buildings with wooden truss-tile roof structures.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] This utility model provides a duct support frame on a wooden beam. Through the coordinated action of the crossbeam, the first spring and the two vertical rods, the duct is reliably connected to the wooden beam, thereby solving the problem that traditional duct installation methods cannot be directly applied to old buildings with wooden truss-tile roof structures.

[0027] This utility model provides a duct support system that reliably connects the duct to the wooden beam through the coordinated action of the crossbeam, the first spring, and the two vertical rods in each duct support frame. This solves the problem that traditional duct installation methods cannot be directly applied to old buildings with wooden truss-tile roof structures. Attached Figure Description

[0043] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0044] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship.

For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0048] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.
