A standardized temporary support node structure based on quick assembly and disassembly

Abstract

This invention discloses a standardized temporary support node structure based on quick assembly and disassembly, comprising a vertical pole, a horizontal crossbar, and at least one connecting plate. The outer wall of the vertical pole has at least one connecting plate with at least one slot. The end of the horizontal crossbar has a connector, and the lower side of the connector has an insert block for insertion into and mating with the slot. The insert block has an anti-detachment mechanism. In this standardized temporary support node structure based on quick assembly and disassembly, the lower surface of the connector has an integrally formed insert block, and the connecting plate has a wedge-shaped slot. When the horizontal crossbar is fixed to the connecting plate, the insert block mates with the slot. The insert block also has an anti-detachment structure to prevent it from coming loose. On the one hand, this achieves integration, reducing the number of parts to be assembled and improving assembly efficiency and convenience. On the other hand, the integral molding of the insert block and connector, with the connector connected to the horizontal crossbar, not only reduces the risk of missing parts but also, under longitudinal force on the horizontal crossbar, prevents the insert block from shifting upwards, resulting in better stability.

Description

Technical Field

[0001] This invention relates to a standardized temporary support node structure based on rapid assembly and disassembly. Background Technology

[0002] In construction engineering, the support system is a crucial structural element, such as the support for scaffolding and formwork. The connection methods of the support system directly impact construction efficiency, safety, and turnover costs. Currently, common support nodes mainly include coupler-type nodes, cup-lock nodes, and disc-lock nodes. Coupler-type nodes use bolts to fasten couplers connecting horizontal and vertical bars, and their load-bearing capacity depends on the bolt tightening torque, making them susceptible to manual operation. Cup-lock nodes have gaps between the cup and the horizontal bar joint, limiting node rigidity. Disc-lock nodes use pin connections, with the pins and disc holes often having a clearance fit, leading to slight slippage in the initial stage of stress, and the pins are prone to loss. Therefore, existing technologies all suffer from issues such as the need for improved component standardization, complex construction, and the requirement for manual inspection. Summary of the Invention

[0003] To address the above shortcomings, the purpose of this invention is to provide a standardized temporary support node structure that improves installation efficiency and facilitates installation.

[0004] The specific technical solution of the present invention to solve the above-mentioned technical problems is as follows: a standardized temporary support node structure based on quick assembly and disassembly, including a vertical pole, a horizontal bar and at least one connecting plate. The outer wall of the vertical pole is provided with at least one connecting plate, and the connecting plate is provided with at least one slot. The end of the horizontal bar is provided with a connector, and the lower side of the connector is provided with a plug. The plug is used to insert into the slot and cooperate with the slot. The plug is provided with an anti-detachment mechanism.

[0005] Furthermore, the slot is a wedge-shaped hole, and the width and / or length of the slot gradually decreases along the depth direction, and the insert is a wedge-shaped block that matches the wedge-shaped hole.

[0006] Furthermore, the lower side of the connecting plate is provided with an angle iron, the length of the insert is greater than the depth of the slot and extends to one side of the angle iron, and also includes a diagonal rod. The angle iron is provided with a fixing hole, and the diagonal rod is fixed to the angle iron by bolts.

[0007] Furthermore, the insert block is provided with holes, and bolts pass through the insert block and angle iron for fixing.

[0008] Furthermore, the angle iron includes two longitudinally parallel support plates, with a slot formed between the two support plates. The insert block engages with the slot, and the end of the insert block is hook-shaped. The end of the insert block can pass through the slot hole, and the end of the insert block engages with a bolt so that the bolt limits the end of the insert block.

[0009] An angle iron is provided on the lower side of the connecting plate. The length of the insert is greater than the depth of the slot and extends to one side of the angle iron. The angle iron includes two longitudinally parallel support plates, and a slot is formed between the two support plates. The insert cooperates with the slot. The end of the insert is hook-shaped and can pass through the slot. A limiting rod is provided between the two support plates. The end of the insert cooperates with the limiting rod so that the limiting rod limits the end of the insert.

[0010] Furthermore, the end of the insert is provided with a T-shaped block protruding to both sides, the support plate extends downward with a limiting piece, and a concave angle is formed between the limiting piece and the support plate. The T-shaped block is inserted into the concave angle to form a second anti-detachment structure.

[0011] Furthermore, the connector is L-shaped, the horizontal crossbar is threaded to the connector, one side of the connector is disposed on the upper surface of the connecting plate, and the connector has a hole corresponding to the slot of the connecting plate.

[0012] The angle iron includes two longitudinally parallel support plates, forming a slot between the two support plates. The insert block mates with the slot. An angle iron is provided on the lower side of the connecting plate. The length of the insert block is greater than the depth of the slot and extends to one side of the angle iron. The angle iron includes two longitudinally parallel support plates, forming a slot between the two support plates. The insert block mates with the slot. A rotation limiting block is provided at the end of the insert block. The rotation limiting block can rotate and is supported on the lower end of the angle iron.

[0013] The beneficial technical effects of this invention are as follows: This invention discloses a standardized temporary support node structure based on quick assembly and disassembly. A horizontal crossbar is connected to a connector. An insert block is integrally formed on the lower surface of the connector. A wedge-shaped slot is provided on the connector plate. When the horizontal crossbar is fixed to the connector plate, the insert block engages with the slot. The insert block also has an anti-detachment structure to prevent it from coming loose. This achieves integration, reducing the number of parts to be assembled and improving assembly efficiency and convenience. Furthermore, the integral forming of the insert block and connector, with the connector connected to the horizontal crossbar, not only reduces the risk of missing parts but also ensures better stability as the horizontal crossbar is subjected to longitudinal force, making it less prone to upward displacement of the insert block. The lower middle position of the insert block also provides an anti-detachment device, solving the problem in existing technologies where the pin is an independent component, confined in the slot by friction, making it more prone to relative slippage, affecting the stability of the support system, and even causing it to come loose.

[0016] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0017] Reference Figures 1 to 8As shown, the present invention discloses a standardized temporary support node structure based on quick assembly and disassembly, comprising a vertical pole 2, a horizontal crossbar 4, and a connecting plate 3. The connecting plate 3 is fixed to the vertical pole 2, and the horizontal crossbar 4 is fixed to the connecting plate 3, forming a three-dimensional support system 1. Specifically, the vertical pole 2 and the horizontal crossbar 4 can be hollow steel pipes, the connecting plate 3 is a flat circular plate, horizontally welded to the vertical pole 2, the distance between adjacent connecting plates 3 is a fixed length, and the connecting plate 3 is provided with several vertically penetrating slots 7 at equal intervals. The end of the horizontal crossbar 4 is provided with a connector 6, which has a threaded hole. The end of the horizontal crossbar 4 can be threaded into the threaded hole of the connector 6. Of course, the end of the horizontal crossbar 4 can also be fixedly connected to the connector 6, such as by welding. In this embodiment, the connector 6 is L-shaped, and the upper part of the connecting plate 3 is a plate. The lower surface of the plate is flat and horizontally positioned, allowing it to contact and engage with the upper surface of the connecting plate 3. A downwardly protruding insert 8 is integrally formed on the lower side of the plate. The insert 8 is used to insert into and engage with the slot 7. An anti-detachment mechanism is provided on the insert 8 to prevent it from coming out of the slot 7. This embodiment uses an insert 8 integrally formed with the connector 6 instead of a pin. This achieves integration, reduces the number of parts to be assembled, and improves assembly efficiency and convenience. Furthermore, the integral formation of the insert 8 with the connector 6, and the connection between the connector 6 and the horizontal crossbar 4, not only reduces the risk of missing parts but also ensures better stability as the horizontal crossbar 4 is subjected to longitudinal force, making it less likely for the insert 8 to shift upwards. An anti-detachment device is also provided at the lower middle position of the insert 8. In contrast, the pin in the prior art is an independent component, confined in the slot 7 by friction, making it more prone to relative slippage, affecting the stability of the support system 1, and even causing it to come out.

[0018] Reference Figure 1 and Figure 2 The slot 7 can be a wedge-shaped hole, with its width and / or length gradually decreasing along the depth direction. The longitudinal section of the slot 7 can be a right trapezoid or an isosceles trapezoid. The insert 8 is a wedge-shaped block that matches the wedge-shaped hole. In this embodiment, both the slot 7 and the insert 8 are shaped with a larger upper side and a smaller lower side. The horizontal crossbar 4 is subjected to a downward force, and the insert 8 tends to move downward, making the fit between the slot 7 and the insert 8 increasingly tight and stable.

[0019] Reference Figure 3 , Figure 5 and Figure 6An angle iron 9 is provided on the lower side of the connecting plate 3. The angle iron 9 is a reinforcing structure that can strengthen the node structure. Fixing holes can be provided on the angle iron 9. Traditionally, the diagonal bar 10 is connected to the connecting plate 3. When multiple horizontal bars 4 and diagonal bars 10 need to be installed at the same node, the connecting plate 3 will become crowded and inconvenient to install. Moreover, the space of the connecting plate 3 is limited, and too many slots 7 also affect the structural strength of the connecting plate 3 to a certain extent. In this embodiment, the diagonal bar 10 is connected to the angle iron 9 by bolts 11, which can avoid the above problems. The length of the insert 8 can be greater than the depth of the slot 7 and extend to one side of the angle iron 9. The insert 8 has holes, and the bolts 11 pass through the insert 8 and the angle iron 9 to fix it and form an anti-detachment structure. The diagonal bar 10 generally bears tensile force. The upper end of the diagonal bar 10 can be installed using this structure, so that the insert 8 is not easy to slide upward. The lower end of the diagonal bar 10 can continue to be connected to the connecting plate 3 or connected to another angle iron 9 through a joint. This embodiment cleverly incorporates the bolts 11 installed on the diagonal brace 10 as part of the anti-loosening structure, simplifying the components and installation steps.

[0020] Reference Figure 5 and Figure 6 In another embodiment, the angle iron 9 includes two longitudinally parallel support plates 901, forming a slot between the two support plates 901. The insert 8 engages with the slot, and the end of the insert 8 is hook-shaped, allowing it to pass through the slot hole 7. The hook-shaped structure at the end of the insert 8 engages with the bolt 11, limiting the end of the insert 8. The insert 8, made of metal, has a certain degree of elasticity. When the insert 8 is inserted into its hook-shaped end and contacts the bolt 11, a certain pressure is applied to cause it to undergo a certain elastic deformation. After being inserted into place, the hook-shaped end returns to its original position and engages with the bolt 11. Alternatively, the crossbar can be installed first, followed by the bolt 11 for the diagonal bar. In the above embodiment, the hook-shaped end may not engage with the bolt 11. Instead, a limiting rod 12 is provided between the two support plates 901, and the end of the insert 8 engages with the limiting rod 12, limiting the end of the insert 8.

[0021] Reference Figure 7 and Figure 8 The end of the insert 8 may also be provided with a T-shaped block 13 protruding to both sides. The support piece 901 extends downward with a limiting piece 902, and a concave angle is formed between the limiting piece 902 and the support piece 901. The T-shaped block 13 is inserted into the concave angle to form a second anti-detachment structure. This embodiment, together with the above-mentioned anti-detachment structure, forms a double anti-detachment structure to ensure structural safety and reliability.

[0022] Reference Figure 9 In other embodiments, the end of the insert 8 is not provided with a hook-shaped structure or a hole, but is provided with a rotation limiting block 5. The rotation limiting block 5 can rotate and be supported on the lower end of the angle iron 9, thereby cooperating with the angle iron 9 to form an anti-detachment structure.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
