Description

Technical Field

[0001] This utility model relates to the field of scaffolding, specifically a cantilevered scaffolding for tank construction. Background Technology

[0002] In modern industrial construction, tank construction is a common engineering operation, such as the construction and maintenance of petrochemical storage tanks and large water storage tanks. During tank construction, cantilevered scaffolding serves as an important auxiliary construction facility, providing a stable working platform for construction workers and ensuring that they can safely and efficiently perform various operations such as welding, corrosion protection, and installation on the tank.

[0003] Currently, the cantilevered scaffolding used in tank construction typically employs traditional assembly methods, such as connecting and assembling steel pipes using couplers. However, this method has several problems. On the one hand, the assembly process requires a large number of couplers, making the operation cumbersome, inefficient, and costly in terms of manpower and time. On the other hand, the coupler connection method is prone to loosening over long-term use, leading to a decrease in the stability of the scaffolding structure, posing significant safety hazards, and failing to effectively protect the lives of construction workers. Furthermore, the existing methods of fixing the cantilevered scaffolding to the bottom of the tank are not stable enough and cannot adapt to the complex environment and working conditions required for tank construction. It is prone to shaking or displacement during construction, affecting construction quality and progress. In view of this, the inventors urgently need to design a new type of scaffolding structure that can be quickly assembled, prevents loosening, and has a stable structure to improve safety, stability, and construction efficiency. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a cantilevered scaffold for tank construction, so as to solve the technical problems of traditional scaffold assembly being cumbersome, easy to loosen, and unstable to be fixed to the tank.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cantilever scaffold for tank construction, comprising a support pier and a tank body. A limiting insertion hole is provided on the support pier, and a main vertical rod is inserted into the limiting insertion hole. A secondary vertical rod is provided on one side of the main vertical rod. Parallel cantilever horizontal rods are welded between the main vertical rod and the secondary vertical rod. Multiple sets of positioning holes are equidistantly provided on the cantilever horizontal rod. A footboard is placed on the cantilever horizontal rod, and positioning rods that cooperate with the positioning holes are welded to both ends of the footboard. The footboard and the cantilever horizontal rod are quickly positioned and installed through an insertion method.

[0006] By adopting the above technical solution, the precise matching between the limiting holes on the support piers and the main vertical rods enables rapid assembly and accurate positioning, greatly improving construction efficiency. This design avoids the problem of complex fastener connections required by traditional scaffolding, simplifies the installation process, and reduces on-site operation time.

[0007] Furthermore, the pedal is an arc-shaped steel plate that matches the curvature of the tank body. Its surface is provided with anti-slip patterns, and two positioning insertion rods are welded at each end. Each group of pedals corresponds to four positioning holes.

[0008] By adopting the above technical solution, the pedal is designed with an arc-shaped steel plate that matches the curvature of the tank body. This shape that conforms to the curved surface of the tank body can maximize the utilization rate of the working platform, providing a more comfortable and safer working surface for construction workers. The anti-slip pattern design on its surface effectively prevents the risk of construction workers slipping under wet conditions.

[0009] Furthermore, the main vertical rod and the auxiliary vertical rod are of equal length, both are parallelly arranged with circular-section steel pipes, and a rigid framework is formed by welding a number of equally spaced cantilever crossbars between them.

[0010] By adopting the above technical solution, the design of parallelly arranging the main vertical rod and the auxiliary vertical rod with equal-length circular-section steel pipes simplifies the production process through standardized components and reduces the manufacturing cost. The selection of circular-section steel pipes not only ensures the structural strength but also facilitates the direction adjustment during on-site installation.

[0011] Furthermore, a diagonal tension rod is also welded between the main vertical rod and the auxiliary vertical rod, and this diagonal tension rod forms a triangular stable structure with the lowermost cantilever crossbar.

[0012] By adopting the above technical solution, the triangular stable structure formed by the diagonal tension rod and the lowermost cantilever crossbar is one of the most stable geometric shapes in engineering mechanics, which can effectively resist lateral forces and torsional forces. This design significantly improves the overall stiffness of the scaffold and can still remain stable under the common wind forces during the construction of the tank body.

[0013] Furthermore, the support pier adopts a "day" - shaped steel structure framework. Its top surface is annularly and arrayedly distributed with limiting jacks that penetrate through the upper and lower layers. The main vertical rod can be inserted to the bottom of the support pier, and the support pier limits it.

[0014] By adopting the above technical solution, the support pier is designed with a "day" - shaped steel structure framework. This structure has excellent bending and torsional resistance performance and can provide a stable foundation support for the entire scaffold system. The design of the annularly arrayed and penetrating limiting jacks realizes the precise positioning and rapid installation of the main vertical rod.

[0015] Furthermore, the limiting jacks opened on the support pier penetrate through the upper two - layer structure, and after the main vertical rod is inserted into the interior of the limiting jacks, it contacts the upper surface of the bottom of the support pier.

[0016] By adopting the above technical solution, the design of the limiting jacks that penetrate through the upper and lower layers on the support pier ensures the perpendicularity of the main vertical rod through double-layer constraints, effectively preventing installation deviations. The structural feature that the main vertical rod directly contacts the bottom of the support pier realizes the direct transfer of loads and improves the support efficiency.

[0017] Furthermore, the positioning plug rod adopts a wedge-shaped head design. The inclined surface of its head forms a guiding fit with the inner wall of the positioning hole, and an anti-collision rounded corner is provided at the top of the head.

[0018] By adopting the above technical solution, the positioning plug rod adopts a wedge-shaped head design, and the guiding fit formed by its inclined surface and the inner wall of the positioning hole realizes the rapid and accurate positioning installation of the pedal, improving work efficiency. The anti-collision rounded corner design protects the edge of the positioning hole and extends the service life.

[0019] In summary, the main beneficial effects of the present utility model are as follows:

[0020] 1. In the present utility model, the support pier and the main vertical rod adopt a plug-in connection method, which is convenient for rapid erection and disassembly, can effectively improve the construction efficiency. The main and auxiliary vertical rods, the cantilever cross bar and the diagonal tie rod form a rigid framework, and the triangular stable structure enhances the overall stability, providing reliable safety protection for construction workers. At the same time, the "day" - shaped structural framework of the support pier and the design of the limiting jacks ensure the stable positioning of the main vertical rod;

[0021] 2. In the present utility model, the pedal and the cantilever cross bar are quickly positioned and installed through the positioning plug rod and the positioning hole, with simple operation. The arc-shaped anti-slip pedal matches the arc of the tank body, increasing the contact area and having good anti-slip effect. The wedge-shaped head and anti-collision rounded corner design of the positioning plug rod not only facilitate insertion into the positioning hole, but also reduce collision wear and extend the service life of the scaffold, fully meeting the complex requirements of tank construction.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In this embodiment:

[0029] A type of cantilevered scaffolding for tank construction, such as Figure 1-4 As shown, the system includes a support pier 1 and a tank body 10. A limiting insertion hole 2 is provided on the support pier 1, into which a main vertical rod 3 is inserted. A secondary vertical rod 4 is provided on one side of the main vertical rod 3. Parallel cantilevered horizontal rods 5 are welded between the main vertical rod 3 and the secondary vertical rod 4. Multiple sets of positioning holes 7 are equidistantly provided on the cantilevered horizontal rods 5. A footboard 8 is placed on the cantilevered horizontal rod 5, and positioning rods 9 that mate with the positioning holes 7 are welded to both ends of the footboard 8. The footboard 8 and the cantilevered horizontal rod 5 are quickly positioned and installed through this insertion method. The precise cooperation between the limiting insertion hole on the support pier and the main vertical rod enables rapid assembly and accurate positioning, significantly improving construction efficiency. This design avoids the problem of complex fastener connections required by traditional scaffolding, simplifies the installation process, and reduces on-site work time. The rigid frame formed by the main and secondary vertical rods, combined with the parallel distribution of the cantilevered horizontal rods, constructs a stable support system that can effectively withstand various loads during construction, improving construction safety.

[0030] See Figure 1 , Figure 2 , Figure 3 The footboard 8 is an arc-shaped steel plate that matches the curvature of the tank body 10. Its surface is decorated with anti-slip textures, and two positioning rods 9 are welded to each end. Each set of footboard 8 corresponds to four positioning holes 7. The footboard adopts an arc-shaped steel plate design that matches the curvature of the tank body. This shape that fits the curved surface of the tank can maximize the utilization rate of the working platform and provide construction personnel with a more comfortable and safer working surface. Its anti-slip texture design effectively prevents the risk of construction personnel slipping in wet and slippery conditions. The structural design of welding two positioning rods to each end of the footboard enhances the stability of the footboard through a four-point fixing method, ensuring that the footboard remains stable when subjected to dynamic loads, providing a safer and more reliable working platform for high-altitude operations.

[0031] See Figure 1 , Figure 2, the main vertical rod 3 and the auxiliary vertical rod 4 are of equal length and are both arranged in parallel using circular-section steel pipes. A rigid framework is formed by welding a number of equally spaced cantilever crossbars 5 between them. The design of using equal-length circular-section steel pipes for the main and auxiliary vertical rods arranged in parallel simplifies the production process through standardized components and reduces the manufacturing cost. The selection of circular-section steel pipes not only ensures the structural strength but also facilitates the direction adjustment during on-site installation. The rigid framework formed by welding a number of equally spaced cantilever crossbars creates a uniformly distributed force system, which can effectively disperse the construction load and extend the service life.

[0032] Refer to Figure 1 、 Figure 2 、 Figure 4 , a diagonal bracing rod 6 is also welded between the main vertical rod 3 and the auxiliary vertical rod 4. The diagonal bracing rod 6 and the lowermost cantilever crossbar 5 form a triangular stable structure. The triangular stable structure formed by the diagonal bracing rod and the lowermost cantilever crossbar is one of the most stable geometric shapes in engineering mechanics, which can effectively resist lateral forces and torsional forces. This design significantly improves the overall stiffness of the scaffolding and can still remain stable under the common wind force during the construction of the tank body. The triangular support structure effectively transfers the load of the cantilever part to the main support system, reduces the deflection deformation at the cantilever end, and ensures the flatness of the working platform.

[0033] Refer to Figure 1 、 Figure 2 、 Figure 4 , the support pier 1 adopts a "day" - shaped steel structure framework, and its top surface is annularly and arrayedly distributed with limit jacks 2 that penetrate through the upper and lower two layers. The main vertical rod 3 can be inserted into the bottom of the support pier 1, and the support pier 1 limits it. The design of the support pier adopting a "day" - shaped steel structure framework has excellent bending and torsional resistance performance, which can provide a stable foundation support for the entire scaffolding system. The design of the annularly arrayed through - type limit jacks realizes the precise positioning and rapid installation of the main vertical rod. The structural feature that the main vertical rod can be inserted into the bottom of the support pier forms a direct force transmission path, avoiding the stress concentration problem of intermediate connectors.

[0034] Refer to Figure 1 、 Figure 2 、 Figure 4 , the limit jacks 2 opened on the support pier 1 penetrate through the upper two - layer structure. After the main vertical rod 3 is inserted into the interior of the limit jacks 2, it contacts the upper surface of the bottom of the support pier 1. The design of the through - type limit jacks that penetrate through the upper and lower two layers on the support pier ensures the verticality of the main vertical rod through double - layer constraints, effectively preventing installation deviation. The structural feature that the main vertical rod directly contacts the bottom of the support pier realizes the direct transmission of the load, improves the support efficiency, facilitates the inspection of the installation quality, ensures that each connection point meets the design requirements, is suitable for construction scenarios that require long - term use, and reduces the workload of later maintenance.

[0035] Refer to Figure 1 , Figure 2 . The positioning insertion rod 9 adopts a wedge-shaped head design. The inclined surface of its head forms a guiding fit with the inner wall of the positioning hole 7. An anti-collision round corner is provided at the top of the head. The positioning insertion rod adopts a wedge-shaped head design, and the guiding fit formed by its inclined surface and the inner wall of the positioning hole realizes the rapid and accurate positioning installation of the pedal, improves the working efficiency. The anti-collision round corner design protects the edge of the positioning hole and extends the service life. This plugging method avoids the inconvenience of traditional bolt connection that requires tool operation, realizes true rapid disassembly and assembly, and provides a strong guarantee for the construction progress.

[0036] The implementation principle of this embodiment is as follows: First, arrange the support piers 1 in an annular array in the construction area, and ensure the foundation stability through its "day"-shaped steel structure frame; then insert the main vertical rod 3 into the limit jacking holes 2 penetrating the upper and lower layers on the support pier 1 until it contacts the bottom of the support pier 1 to form a vertical load-bearing system; then arrange the equal-length auxiliary vertical rods 4 in parallel on one side of the main vertical rod 3, and weld them with a number of equally spaced cantilever crossbars 5 to form a rigid frame, and weld the diagonal tension rods 6 between the main vertical rod 3 and the auxiliary vertical rod 4 to form a triangular stable structure with the lowest cantilever crossbar 5; finally, insert the arc-shaped pedal 8 matching the radian of the tank body 10 into the positioning holes 7 on the cantilever crossbar 5 through the positioning insertion rods 9 welded at both ends, and use the wedge-shaped head design and anti-collision round corner of the positioning insertion rod 9 to realize rapid positioning installation, and complete the construction of the entire cantilever scaffold. This structure realizes a safe and stable construction platform for the tank body through the collaborative action of the limit plugging of the support pier 1, the rigid frame of the main vertical rod 3 and the auxiliary vertical rod 4, the triangular stability of the diagonal tension rod 6, and the rapid positioning system of the pedal 8.
