Description

Technical Field

[0001] This utility model relates to the technical field of pipeline installation, specifically to a joint fixing device for multiple pipelines. Background Technology

[0002] In electromechanical installation projects, combinations of wooden supports, U-shaped pipe clamps, and brackets are frequently used to secure pipes and ensure their normal operation. In existing technology, each pipe is fixed to a bracket using one wooden support and one U-shaped pipe clamp. Each wooden support consists of two parts that can be combined, with the central space perfectly securing the pipe after assembly.

[0003] The existing technology for pipeline installation has the following main problems: 1. Each pipeline requires a separate wooden support and clamp for fixation. Fixing multiple pipelines requires multiple wooden supports and multiple U-shaped pipe clamps, resulting in many accessories, labor and material costs, and low installation efficiency; 2. The wooden supports rely solely on friction to fix their position. They are easily misaligned or fall off due to pipeline vibration, thermal expansion and contraction, and lose their supporting function for the pipeline. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-pipe joint fixing device that has few accessories, is easy to install, and is firmly fixed.

[0005] The technical solution adopted by this utility model is as follows: a multi-pipe joint fixing device, including a support plate, a bracket, and a fixing mechanism. The support plate is composed of an inner support plate and an outer support plate of the same length, which are aligned and spliced ​​together. The inner support plate and the outer support plate are respectively provided with multiple semi-circular holes symmetrically on their contact surfaces. After the inner support plate and the outer support plate are combined, multiple circular holes are formed in the middle. The inner diameter of the circular holes is consistent with the outer diameter of the pipe to be fixed. The bracket includes support arms with spacing matching the length of the support plate. The outer ends of the two support arms are respectively connected to the two ends of a connecting arm. The inner support plate and the outer support plate are provided with support plate fixing holes through the width direction of the support plate on both sides along the length direction. The connecting arm is provided with support fixing holes through the support fixing holes on both sides corresponding to the support plate fixing holes. The fixing mechanism includes fixing bolts and anti-loosening nuts. The fixing bolts pass through the support fixing holes and the support plate fixing holes of the inner support plate and the outer support plate. Anti-loosening nuts are installed at the ends and tightened to fix the inner support plate, the outer support plate, and the multiple pipes to be fixed.

[0006] Furthermore, both the inner and outer support plates are made of polyurethane.

[0007] Furthermore, the thickness of the inner and outer support plates is 40mm.

[0008] Furthermore, the bracket is made of 40*40mm square steel.

[0009] Furthermore, the end of the support arm away from the connecting arm is connected to the structural surface by pre-embedding, welding, or bolting.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model uses an integrated tray design, which only requires one set of trays and a pair of bolts to fix multiple pipes. The fixing bolts pass through the fixing holes of the bracket and the tray, and are tightened by anti-loosening nuts to achieve dual limiting of the tray and the pipe. The net width between the two support arms is consistent with the overall width of the tray, which can fix the left and right position of the tray. It has fewer accessories, is easy to install, and has high installation efficiency.

[0012] 2. The pallet consists of an inner pallet and an outer pallet, which has good overall integrity. The pallet is fixed to the bracket by the fixing bolts, and the bracket arm also effectively fixes the left and right positions of the pallet, completely eliminating the hidden dangers of pallet shifting or falling off.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 and Figure 2As shown, a multi-pipe joint fixing device includes a support plate 1, a bracket 2, and a fixing mechanism 3. The support plate 1 is composed of an inner support plate 11 and an outer support plate 12 of the same length, joined together with their long sides aligned. The inner support plate 11 and the outer support plate 12 are respectively provided with multiple semi-circular holes symmetrically on their contact surfaces. After the inner support plate 11 and the outer support plate 12 are combined, multiple circular holes are formed in the middle. The inner diameter of the circular holes is consistent with the outer diameter of the pipe to be fixed. The bracket 2 includes support arms 21 with spacing matching the length of the support plate 1. The outer ends of the two support arms 21 are respectively connected to... At both ends of a connecting arm 22, the inner support plate 11 and the outer support plate 12 are provided with support plate fixing holes 13 through the width direction of the support plate 1 on both sides of the length direction. Corresponding to the support plate fixing holes 13, the two sides of the connecting arm 22 are provided with bracket fixing holes 23. The fixing mechanism 3 includes fixing bolts 31 and anti-loosening nuts 32. The fixing bolts 31 pass through the bracket fixing holes 23, the inner support plate 11 and the outer support plate 12 support plate fixing holes 13, and the anti-loosening nuts 32 are installed at the ends and tightened to fix the inner support plate 11 and the outer support plate 12 and the multiple pipes that need to be fixed.

[0020] Both the inner support plate 11 and the outer support plate 12 are made of materials with low thermal conductivity and a certain strength, which can effectively isolate heat transfer. In this embodiment, both the inner support plate 11 and the outer support plate 12 are made of polyurethane with a thickness of 40mm. Figure 3 As shown, six semi-circular holes are symmetrically arranged on one side of the contact surface between the inner support plate 11 and the outer support plate 12. After assembly, six circular holes are formed at the contact surface. The inner diameter of the circular holes is consistent with the outer diameter of the pipes to be fixed, and they are used to fix the six pipes. Support plate fixing holes 13 with a diameter of 13mm are provided on corresponding positions on both sides of the inner support plate 11 and the outer support plate 12.

[0021] like Figure 4 As shown, the bracket 2 has an overall "⊔" shaped structure and is made of 40*40mm square steel. The bracket 2 includes a support arm 21 and a connecting arm 22. The clear width between the two support arms 21 is consistent with the overall length of the tray 1, which can fix the left and right positions of the tray 1. The connecting arm 22 is provided with two bracket fixing holes 23, the diameter of which is 13mm, and their positions correspond to the positions of the tray fixing holes 13.

[0022] The anchoring method of the bracket 2 on the structural surface can be any of the existing technologies such as pre-embedding, welding, or bolt connection, which will not be elaborated here.

[0023] The fixing mechanism 3 consists of a fixing bolt 31 and a lock nut 32. After the fixing bolt 31 passes through the bracket fixing hole 23, the inner support plate 11 and the outer support plate 12 support plate fixing hole 13, the lock nut 32 is installed at the end and tightened to fix the inner support plate 11 and the outer support plate 12 as well as multiple pipes that need to be fixed. After tightening, 3-5 threads are exposed.

[0024] This utility model, through its integrated tray design, requires only one set of trays 1 and a pair of bolts to fix multiple pipes. At the same time, the bracket 21 of the support 2 restricts the lateral displacement of the tray 1, and the bolts provide through-fixation, completely solving the problem of traditional wooden trays being prone to displacement and falling off. The device is simple and efficient to operate and is suitable for multi-pipe installation scenarios.
