Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and in particular to a high-strength support steel pipe. Background Technology

[0002] In modern engineering construction, supporting steel pipes play an irreplaceable role. With their excellent load-bearing and transmission capabilities, they provide reliable support for numerous objects and structures and are widely used in many key fields such as construction, industry, and agriculture.

[0003] In the construction industry, supporting steel pipes are used to erect scaffolding, providing safety for construction workers working at heights. During the main building construction, they stabilize the formwork, ensuring smooth concrete pouring. In the industrial sector, large towers in petrochemical plants and power transmission towers in power projects rely on supporting steel pipes for stability, ensuring stable industrial production and power transmission. In agriculture, supporting steel pipes form the framework of greenhouses, resisting adverse weather conditions and serving as horticultural supports to aid crop growth. However, the single-layer steel pipe structure commonly used in various fields has significant drawbacks. Its stability is poor, lacking an effective stress dispersion mechanism in the face of complex and changing external environments and loads. At construction sites, strong winds, worker activity, and material stacking can cause lateral displacement of single-layer scaffolding steel pipes, threatening construction safety. In industrial settings, single-layer steel pipes supporting equipment are prone to tilting and collapse in extreme situations such as earthquakes and strong winds, leading to serious accidents. In agricultural production, greenhouses encountering strong winds and blizzards cannot withstand the loads of single-layer steel pipe frameworks, causing greenhouse collapse and crop damage.

[0004] It is evident that the insufficient stability of single-layer supported steel pipes severely hinders their application and development in fields requiring high structural stability. To meet the ever-evolving engineering demands, innovative research is urgently needed to develop new steel pipe structures or improve existing technologies to overcome this technical bottleneck. Utility Model Content

[0005] Based on this, and in response to the above problems, this utility model proposes a high-strength supporting steel pipe, which solves the problem of poor stability of current supporting steel pipes during use.

[0006] The technical solution of this utility model is:

[0007] A high-strength support steel pipe includes a pair of steel pipe bodies, one end of which is detachably connected;

[0008] The main body of the steel pipe includes a supporting steel pipe and a reinforcing steel pipe. The reinforcing steel pipe is sleeved on the outside of the supporting steel pipe and is slidably connected to the supporting steel pipe. Both ends of the reinforcing steel pipe are detachably connected to both ends of the supporting steel pipe.

[0009] The outer side of the supporting steel pipe is provided with several reinforcing ribs, which are fixedly connected to the outer side of the supporting steel pipe. The inner side wall of the reinforcing steel pipe is provided with several mating grooves that cooperate with the reinforcing ribs. When the reinforcing steel pipe is connected to the supporting steel pipe, the reinforcing ribs are respectively located in the mating grooves, and the reinforcing ribs are slidably connected to the mating grooves.

[0010] Preferably, the supporting steel pipe has a connecting plate at one end and a limiting plate at the other end. The connecting plate is fixedly connected to the supporting steel pipe, and the limiting plate is detachably connected to the supporting steel pipe. The reinforcing steel pipe has fixing plates at both ends. The fixing plates are fixedly connected to the reinforcing steel pipe. The fixing plate at one end of the reinforcing steel pipe is detachably connected to the connecting plate, and the fixing plate at the other end of the reinforcing steel pipe is detachably connected to the limiting plate.

[0011] Preferably, the connecting discs of a pair of supporting steel pipes in a pair of steel pipe bodies can contact each other at one end and are detachably connected by bolts.

[0012] Preferably, the fixing plate and the connecting plate at one end of the reinforcing steel pipe are detachably connected by bolts.

[0013] Preferably, the fixing plate and the limiting plate at the other end of the reinforcing steel pipe are detachably connected by bolts.

[0014] Preferably, one end of the limiting plate is provided with an insertion steel pipe, one end of which can pass through the fixing plate and be inserted into the supporting steel pipe, and is detachably connected to the supporting steel pipe.

[0015] Preferably, a pair of limiting blocks are provided on the inner side wall of the supporting steel pipe, and a pair of combined grooves are provided on the inserted steel pipe. The pair of combined grooves are respectively configured to cooperate with the pair of limiting blocks, and the limiting blocks are slidably connected to the combined grooves. The pair of limiting blocks can cooperate with the pair of combined grooves to form a limiting position.

[0016] Preferably, the combination groove includes an insertion groove and a locking groove. One end of the insertion groove passes through the end of the inserted steel pipe, and the other end is connected to the locking groove. When the inserted steel pipe is inserted into the supporting steel pipe, the limiting block can enter the locking groove from the insertion groove. Then, rotating the limiting plate can move the limiting block in the locking groove to form a matching limiting with the locking groove.

[0017] Preferably, the outer side of the reinforcing steel pipe is provided with several reinforcing ribs, and the several reinforcing ribs are fixedly connected to the outer side of the reinforcing steel pipe.

[0018] Preferably, several reinforcing ribs are integrally formed with the supporting steel pipe, and several reinforcing ribs are integrally formed with the reinforcing steel pipe.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention utilizes a supporting steel pipe and a reinforcing steel pipe, with the reinforcing steel pipe sleeved over the outside of the supporting steel pipe, forming a tight double-support structure. Under load, the supporting steel pipe directly bears part of the pressure, while the reinforcing steel pipe provides additional support from the outside. The two work together to distribute the load and prevent deformation or damage to the supporting steel pipe due to uneven stress. Simultaneously, several reinforcing ribs are provided on the outside of the supporting steel pipe, and several mating grooves are provided on the inner wall of the reinforcing steel pipe. When the reinforcing steel pipe is connected to the supporting steel pipe, the reinforcing ribs and mating grooves mutually restrict each other. On the one hand, this prevents the reinforcing steel pipe from rotating circumferentially on the supporting steel pipe, ensuring that both work synchronously and collaboratively under load. On the other hand, the reinforcing ribs embedded in the mating grooves increase the contact area and friction of the structure, further enhancing the overall structural stability and better resisting deformation under lateral forces or torques. This solves the problem of poor stability in current supporting steel pipe systems. Attached Figure Description

Detailed Implementation

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example:

[0031] like Figures 1 to 3 As shown, in order to solve the above problems, this embodiment discloses a high-strength supporting steel pipe, including a pair of steel pipe bodies 10, one end of which is detachably connected.

[0032] The main body 10 of the steel pipe includes a supporting steel pipe 100 and a reinforcing steel pipe 101. The reinforcing steel pipe 101 is sleeved on the outside of the supporting steel pipe 100 and is slidably connected to the supporting steel pipe 100. The two ends of the reinforcing steel pipe 101 are detachably connected to the two ends of the supporting steel pipe 100 respectively.

[0033] The outer side of the supporting steel pipe 100 is provided with a number of reinforcing ribs 102, which are fixedly connected to the outer side of the supporting steel pipe 100. The inner side wall of the reinforcing steel pipe 101 is provided with a number of mating grooves 103 that cooperate with the reinforcing ribs 102. When the reinforcing steel pipe 101 is connected to the supporting steel pipe 100, the reinforcing ribs 102 are respectively located in the mating grooves 103, and the reinforcing ribs 102 are slidably connected to the mating grooves 103.

[0034] This invention features a supporting steel pipe 100 and a reinforcing steel pipe 101, with the reinforcing steel pipe 101 fitted over the outside of the supporting steel pipe 100, forming a tight double-support structure. Under load, the supporting steel pipe 100 directly bears part of the pressure, while the reinforcing steel pipe 101 provides additional support from the outside. The two work together to distribute the load and prevent deformation or damage to the supporting steel pipe 100 due to uneven stress. Simultaneously, several reinforcing ribs 102 are provided on the outside of the supporting steel pipe 100, and several mating grooves 103 are provided on the inner wall of the reinforcing steel pipe 101. When the reinforcing steel pipe 101 is connected to the supporting steel pipe 100, the reinforcing ribs 102 and the mating grooves 103 mutually restrict each other. On the one hand, this prevents the reinforcing steel pipe 101 from rotating circumferentially on the supporting steel pipe 100, ensuring that both work synchronously and collaboratively under load. On the other hand, the reinforcing ribs 102 embedded in the mating grooves 103 increase the contact area and friction of the structure, further enhancing the overall structural stability and better resisting deformation under lateral forces or torques. This solves the problem of poor stability of the current support steel pipe 100 during use.

[0035] Furthermore, this invention replaces the traditional support steel pipe with a pair of steel pipe bodies 10, with one end of each pair of steel pipe bodies 10 being detachably connected. This modular structure allows for flexible combination of the length of the support steel pipes according to actual usage scenarios and support requirements, while also facilitating transportation.

[0036] As a further preferred embodiment, the reinforcing rib 102 is a semi-circular structure, and the mating groove 103 is a semi-circular groove structure that mates with the reinforcing rib 102.

[0037] like Figures 3 to 4 As shown, in order to ensure sufficient strength at the connection, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the supporting steel pipe 100 is provided with a connecting plate 104 at one end and a limiting plate 105 at the other end. The connecting plate 104 is fixedly connected to the supporting steel pipe 100, and the limiting plate 105 is detachably connected to the supporting steel pipe 100. The reinforcing steel pipe 101 is provided with fixing plates 106 at both ends. The fixing plates 106 are fixedly connected to the reinforcing steel pipe 101. The fixing plate 106 at one end of the reinforcing steel pipe 101 is detachably connected to the connecting plate 104, and the fixing plate 106 at the other end of the reinforcing steel pipe 101 is detachably connected to the limiting plate 105.

[0038] Among them, the connecting discs 104 of the pair of supporting steel pipes 100 in the pair of steel pipe bodies 10 can contact each other at one end and can be detachably connected by bolts.

[0039] The fixing plate 106 at one end of the reinforcing steel pipe 101 is detachably connected to the connecting plate 104 by bolts.

[0040] The fixing plate 106 at the other end of the reinforcing steel pipe 101 is detachably connected to the limiting plate 105 by bolts.

[0041] During assembly, first align the fixing plate 106 at one end of the reinforcing steel pipe 101 with the end of the supporting steel pipe 100 with the connecting plate 104, then insert them, and finally fasten them together with bolts, ensuring a tight connection between the reinforcing steel pipe 101 and the supporting steel pipe 100. Next, align the limiting plate 105 with the fixing plate 106 at the other end of the reinforcing steel pipe 101 and connect them with bolts to complete the assembly of a single steel pipe body 10. When assembling a pair of steel pipe bodies 10, simply align the connecting plates 104 of the pair of supporting steel pipes 100 and connect them with bolts. This allows adjustment of the overall steel pipe length according to actual needs, making it suitable for different support scenarios. This connection method is simple to operate and ensures sufficient strength at the connection points to meet the stress requirements under different working conditions.

[0042] The bolted connection method used between the connecting plate 104, the fixing plate 106, and the limiting plate 105 significantly improves the tightness and robustness of the connection between the various components of the steel pipe compared to traditional connection methods. This connection method can withstand greater tensile and shear forces. In large building structures, such as the support system of high-rise buildings, or in the support structure of industrial equipment, such as the support structure of large chemical reaction towers, it can effectively avoid safety hazards caused by loose connections, ensuring the stability and reliability of the entire structure during long-term use.

[0043] Meanwhile, bolted connections are simple to operate, allowing construction workers to quickly assemble and disassemble steel pipes without the need for complex tools or specialized skills. On construction sites, when adjustments to pipe length are required based on actual conditions, this connection method enables rapid adjustments, significantly shortening construction time, reducing costs, and improving efficiency, making it particularly suitable for projects with tight deadlines.

[0044] like Figure 3 , Figures 5 to 6 As shown, in order to ensure the stability of the connection between the reinforced steel pipe 101 and the supporting steel pipe 100, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that one end of the limiting plate 105 is provided with an insertion steel pipe 107. One end of the insertion steel pipe 107 can pass through the fixing plate 106 and be inserted into the supporting steel pipe 100, and is detachably connected to the supporting steel pipe 100.

[0045] Among them, a pair of limiting blocks 108 are provided on the inner side wall of the supporting steel pipe 100, and a pair of combined grooves 109 are provided on the inserted steel pipe 107. The pair of combined grooves 109 are respectively matched with the pair of limiting blocks 108, and the limiting blocks 108 and the combined grooves 109 are slidably connected. The pair of limiting blocks 108 can respectively match the pair of combined grooves 109 to form a limiting position.

[0046] The combination groove 109 includes an insertion groove 110 and a locking groove 111. One end of the insertion groove 110 passes through the end of the insertion steel pipe 107, and the other end is connected to the locking groove 111. When the insertion steel pipe 107 is inserted into the support steel pipe 100, the limiting block 108 can enter the locking groove 111 through the insertion groove 110. Then, by rotating the limiting disk 105, the limiting block 108 can be moved in the locking groove 111 to form a matching limiting with the locking groove 111.

[0047] The insertion steel pipe 107 at one end of the limiting plate 105 is inserted into the support steel pipe 100 to achieve a stable connection between the reinforcing steel pipe 101 and the support steel pipe 100. The insertion steel pipe 107 has a pair of combination grooves 109, while the inner wall of the support steel pipe 100 has a pair of limiting blocks 108. During installation, the insertion steel pipe 107 is first aligned with the support steel pipe 100 and inserted. At this time, the limiting blocks 108 enter along the insertion groove 110. After the insertion steel pipe 107 is fully inserted, the limiting plate 105 is rotated, causing the insertion steel pipe 107 to rotate as well. This causes the limiting blocks 108 to move within the locking groove 111 until they engage with the locking groove 111, effectively preventing the insertion steel pipe 107 from coming out and ensuring a stable connection between the reinforcing steel pipe 101 and the support steel pipe 100, allowing them to work together under various loads.

[0048] The limiting structure design of the limiting plate 105 and the inserted steel pipe 107 precisely ensures the fixed relative position between the reinforcing steel pipe 101 and the supporting steel pipe 100. In actual use, whether subjected to static or dynamic loads, or even under vibration, it effectively prevents displacement or loosening between the two, ensuring they always work together effectively. This stable connection structure not only enhances the overall structural stability but also reduces additional losses caused by component loosening, thereby extending the service life of the steel pipe and reducing maintenance costs.

[0049] As a further preferred embodiment, the rotation angle of the limiting disk 105 can be set to 30° or 45°.

[0050] like Figure 4 As shown, in order to further enhance the stability of the support, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that a number of reinforcing ribs 112 are provided on the outside of the reinforcing steel pipe 101, and the number of reinforcing ribs 112 are fixedly connected to the outside of the reinforcing steel pipe 101.

[0051] Among them, several reinforcing ribs 102 are integrally formed with the supporting steel pipe 100, and several reinforcing ribs 112 are integrally formed with the reinforcing steel pipe 101.

[0052] The integrally formed reinforcing ribs 112 on the outer side of the reinforcing steel pipe 101 and the integrally formed reinforcing ribs 102 on the outer side of the supporting steel pipe 100 greatly enhance the strength and rigidity of the reinforcing steel pipe 101 and the supporting steel pipe 100. When subjected to load, the reinforcing ribs 112 and reinforcing ribs 102 can share part of the pressure, acting as an additional support structure for the reinforcing steel pipe 101 and the supporting steel pipe. Under greater pressure, the reinforcing ribs 112 can effectively prevent the reinforcing steel pipe 101 from deforming, and the reinforcing ribs 102 on the outer side of the supporting steel pipe 100 can effectively prevent the supporting steel pipe 100 from deforming. Together with the double steel pipe structure, they work synergistically to improve the overall support performance of the steel pipe from multiple directions and levels, enabling it to withstand greater loads and more complex stress conditions.

[0053] The reinforcing ribs 112 and 102, along with the double-tube structure, work together to comprehensively enhance the strength and rigidity of the entire high-strength support steel pipe of this invention from multiple dimensions. The presence of the reinforcing ribs 112 and 102 significantly improves the deformation resistance of the reinforcing steel pipe 101 and the supporting steel pipe 100, enabling the entire high-strength support steel pipe of this invention to maintain structural integrity even under greater loads. This advantage allows the steel pipe to meet the requirements of many special engineering scenarios with extremely high support strength requirements, such as dam support structures in large-scale water conservancy facilities and large equipment supports in aerospace bases, providing a reliable material choice for the construction of special projects.

[0054] Working principle of this utility model:

[0055] This invention features a supporting steel pipe 100 and a reinforcing steel pipe 101, with the reinforcing steel pipe 101 fitted over the outside of the supporting steel pipe 100, forming a tight double-support structure. Under load, the supporting steel pipe 100 directly bears part of the pressure, while the reinforcing steel pipe 101 provides additional support from the outside. The two work together to distribute the load and prevent deformation or damage to the supporting steel pipe 100 due to uneven stress. Simultaneously, several reinforcing ribs 102 are provided on the outside of the supporting steel pipe 100, and several mating grooves 103 are provided on the inner wall of the reinforcing steel pipe 101. When the reinforcing steel pipe 101 is connected to the supporting steel pipe 100, the reinforcing ribs 102 and the mating grooves 103 mutually restrict each other. On the one hand, this prevents the reinforcing steel pipe 101 from rotating circumferentially on the supporting steel pipe 100, ensuring that both work synchronously and collaboratively under load. On the other hand, the reinforcing ribs 102 embedded in the mating grooves 103 increase the contact area and friction of the structure, further enhancing the overall structural stability and better resisting deformation under lateral forces or torques.

[0056] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
