Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and more specifically, particularly relates to a reusable climbing cone connection type construction device. Background Art

[0002] In the field of building construction, especially when it comes to high-altitude operations, large bridge or high-rise building construction, the erection and stability of the construction platform are crucial. The construction platform needs to provide a safe and reliable working space for personnel, materials and equipment, and be able to adapt to complex construction environments and load requirements.

[0003] Structural support components

[0004] 1. Cross bar: Usually used as the main horizontal load-bearing member, it bears the horizontal load on the construction platform and transfers the load to other components.

[0005] 2. Diagonal bar: Together with the cross bar and vertical bar, it forms a triangular stable structure to effectively resist loads from different directions.

[0006] 3. Vertical bar: It mainly bears the vertical load, ensures the vertical support of the construction platform, and works together with the cross bar and diagonal bar to ensure the stability of the structure in the vertical direction.

[0007] Currently, in building construction, in order to achieve the stable erection and efficient use of the construction platform, construction units have adopted a variety of equipment and methods. Some use traditional embedded corbels, pre-burying corbel components in the concrete structure, but their one-time use cost is relatively high, and it is difficult to reuse them after demolition, resulting in waste of resources. Others use simple welded brackets. Although the erection is relatively simple, the structural stability and load-bearing capacity are limited, and it is difficult to meet the safety requirements in complex construction environments, and it is not easy to adjust and reuse. Some large projects have tried to use complex hydraulic lifting platforms. Although they have the function of height adjustment, the equipment cost is high, the maintenance is complex, and the requirements for the construction site and technology are relatively high.

[0008] However, the above-mentioned implementation methods still have the following problems. In terms of structural stability, some construction devices cannot effectively resist complex load combinations, and are prone to deformation or instability under working conditions such as strong winds and vibrations, endangering construction safety. In terms of component reuse, most of the existing devices are not reasonably designed, and it is difficult to achieve multiple reuse of components, resulting in high construction costs and not conforming to the concept of sustainable development. In response to these problems, the present application proposes a reusable climbing cone connection type construction device. By optimizing the structural design, the structural stability and load-bearing capacity are improved, and components such as climbing cones and corbels can be easily reused, reducing the construction cost and effectively solving many problems existing in the existing construction devices.

[0009] In view of this, the existing structures and deficiencies are studied and improved to provide a reusable climbing cone connection type construction device, with the aim of achieving a more practical value. Summary of the Invention

[0010] In order to solve the above technical problems, the present invention provides a reusable climbing cone connection type construction device to solve the above problems.

[0011] A reusable climbing cone connection type construction device includes a cross bar. On the front surface of the cross bar, an inclined bar and a vertical bar are fixedly connected by welding. The inclined bar and the vertical bar are fixed by welding. Two climbing cones are arranged on the left side of the cross bar. A second reinforcing plate and two first reinforcing plates are arranged between the cross bar, the inclined bar and the vertical bar. On the adjacent surfaces of the inclined bar and the cross bar and the vertical bar, third reinforcing blocks are fixedly welded. On the front and rear sides of the vertical bar and the rear surface of the inclined bar, limiting blocks are fixedly connected. On the surface of each limiting block, a group of limiting fins are fixedly connected. On the connected surface of the outer sides of the cross bar and the inclined bar, a second reinforcing block is fixedly connected by welding.

[0012] Preferably, a first steel plate is fixedly connected to the left surface of the inclined bar and the vertical bar by screws. A second steel plate is arranged on the left surface of the cross bar. The second reinforcing plate is fixedly connected to the two third reinforcing blocks.

[0013] Preferably, a first reinforcing block is fixedly welded to the connecting surface of the cross bar and the vertical bar. The two first reinforcing plates are respectively fixedly connected to the two third reinforcing blocks and the first reinforcing block. Limiting grooves are opened on the front surface of the cross bar and the inclined surface of the inclined bar.

[0014] Preferably, each limiting groove is movably clamped with each limiting block respectively. On the inner wall of each limiting groove, a group of connecting grooves are opened. Each group of connecting grooves is movably clamped with each group of limiting fins respectively.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, the bracket structure design is based on the mechanical principle. The triangular structure composed of its members can effectively decompose and transfer the applied load. The vertical load is transmitted through the bracket members to the climbing cone, and then transmitted by the climbing cone to the concrete structure. The bearing capacity of the concrete structure is utilized to resist the external force. The climbing cone is tightly connected to the bracket through its threaded structure to achieve a reliable anchoring effect. The components such as the climbing cone and the bracket are detachable, which enables repeated use, reduces the construction cost, provides a stable support point for the entire construction platform, and prevents the bracket from slipping or being pulled out when bearing the load.

[0017] In the present invention, the triangular web member structure formed by the second reinforcement plate and the two first reinforcement plates can effectively resist the deformation and distortion generated by the triangular corbel when bearing loads. When subjected to external forces, the first reinforcement plate and the second reinforcement plate will evenly distribute the forces to each member, avoiding stress concentration on a certain member or connection part, thereby improving the stability and load-bearing capacity of the entire triangular corbel structure. When there are large concentrated loads or dynamic loads on the construction platform, the triangular web member structure provided can prevent the triangular corbel from undergoing instability failure.

[0018] In the present invention, the shapes and sizes of the limit block and the limit groove are mutually matched. This tight fit can limit the displacement of the inclined rod and the vertical rod relative to the horizontal rod in multiple directions. The depth and width of the limit groove are designed to be slightly larger than the limit block, enabling the limit block to be smoothly inserted and clamped in the limit groove, and there is almost no gap in the horizontal direction (including the transverse and longitudinal directions), thereby effectively preventing the translation and rotation of the members in the horizontal direction.

[0019] In the present invention, the cooperation between the limit fins and the connection groove provides an additional connection guarantee mechanism, increasing the redundancy of the structure. Even if there are certain defects or damages in the welding parts, the frictional force can still maintain the relative positions and connection stability between the members, providing a certain safety reserve for the structure. In extreme cases, such as when some welding points fail, the frictional force can temporarily bear part of the load, preventing the structure from collapsing immediately, providing time and conditions for repair or reinforcement, and further improving the reliability and safety of the triangular corbel under complex construction conditions.

[0029] The following further describes the implementation manners of the present invention in detail in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0030] Please refer to Figure 1 - Figure 8 The present invention provides a reusable climbing cone connection type construction device, including a horizontal bar 1. A diagonal bar 2 and a vertical bar 3 are fixedly connected to the front surface of the horizontal bar 1 by welding. The diagonal bar 2 and the vertical bar 3 are fixed by welding. Two climbing cones 4 are arranged on the left side of the horizontal bar 1. A second reinforcement plate 12 and two first reinforcement plates 8 are arranged between the horizontal bar 1, the diagonal bar 2 and the vertical bar 3. Third reinforcement blocks 11 are fixedly welded to the adjacent surfaces of the diagonal bar 2 with the horizontal bar 1 and the vertical bar 3. Limit blocks 13 are fixedly connected to the front and rear sides of the vertical bar 3 and the rear surface of the diagonal bar 2. A group of limit fins 15 are fixedly connected to the surface of each limit block 13. Second reinforcement blocks 9 are fixedly connected to the adjacent surfaces of the horizontal bar 1 and the diagonal bar 2 by welding. Before the concrete pouring of the cross beam, the climbing cones 4 are accurately embedded according to the design positions to provide an anchoring foundation for the subsequent corbel installation. After the cross beam is poured and the formwork is removed, the corbels are installed. The corbel members (horizontal bar 1, diagonal bar 2 and vertical bar 3) are connected by welding, the welds are full, the weld leg height is not less than 10 mm, E43 type electrodes are used for welding, and wind protection measures are taken. The current is strictly controlled. First reinforcement blocks 7, second reinforcement blocks 9 and third reinforcement blocks 11 are arranged at the joint positions for reinforcement to avoid stress concentration and ensure that the welds meet the stress requirements. The corbels are anchored to the concrete surface by the double climbing cone 4 method at the position of the horizontal bar 1. Then the steps and railings are installed. The corbel structure is designed based on the mechanical principle, and the triangular structure composed of its members can effectively decompose and transfer the applied load. The vertical load is transmitted to the climbing cone 4 through the corbel members, and then transmitted to the concrete structure by the climbing cone 4. The bearing capacity of the concrete structure is utilized to resist the external force. The climbing cone 4 is tightly connected to the corbel through its threaded structure to achieve a reliable anchoring effect. The detachable components such as the climbing cone 4 and the corbel can be reused, reducing the construction cost, providing a stable support point for the entire construction platform, preventing the corbel from slipping or being pulled out when bearing the load. The standardized design and installation method make the construction process relatively simple, reduce the construction time and improve the construction efficiency. Through reasonable structural design and reinforcement measures, it can bear a large load, provide stable support for the construction platform, and ensure the construction safety and quality.

[0031] On the left surface of the diagonal rod 2 and the vertical rod 3, a first steel plate 5 is fixedly connected by screws. On the left surface of the cross rod 1, a second steel plate 6 is provided. The reinforcing plate 2 is fixedly connected to the two reinforcing blocks 3. The triangular web member structure formed by the reinforcing plate 2 and the two reinforcing plates 1 can effectively resist the deformation and distortion generated by the triangular corbel when bearing loads. When subjected to external forces, the reinforcing plate 1 and the reinforcing plate 2 will evenly disperse the forces to each member, avoiding stress concentration on a certain member or connection part, thereby improving the stability and load-bearing capacity of the entire triangular corbel structure. When there is a large concentrated load or dynamic load on the construction platform, the triangular web member structure provided can prevent the triangular corbel from undergoing instability failure. The connection of the two reinforcing plates 1, the reinforcing block 1, the two reinforcing blocks 3 and the reinforcing plate 2 makes the cross rod 1, the diagonal rod 2 and the vertical rod 3 form an organic whole. This integrity enables the triangular corbel to work together during the force-bearing process, the deformations between the members are coordinated with each other, improving the overall stiffness of the structure. Compared with the non-reinforced structure, under the same load, its deformation is smaller, and it can better meet the requirements for structural accuracy and stability during the construction process.

[0032] On the connection surface of the cross rod 1 and the vertical rod 3, a reinforcing block 1 is fixedly connected by welding. The two reinforcing plates 1 are respectively fixedly connected to the two reinforcing blocks 3 and the reinforcing block 1. On the front surface of the cross rod 1 and the inclined surface of the diagonal rod 2, limiting grooves 10 are provided. The shape and size of the limiting block 13 match those of the limiting groove 10. This tight fit can limit the displacement of the diagonal rod 2 and the vertical rod 3 relative to the cross rod 1 in multiple directions. The depth and width of the limiting groove 10 are designed to be slightly larger than those of the limiting block 13, so that the limiting block 13 can be smoothly inserted and clamped in the limiting groove 10, and there is almost no gap in the horizontal direction (including transverse and longitudinal), thereby effectively preventing the translation and rotation of the members in the horizontal direction. When the triangular corbel bears a horizontal load, such as the wind force from the side or the collision force during the construction process, the clamping of the limiting block 13 and the limiting groove 10 can prevent the diagonal rod 2 and the vertical rod 3 from moving to the sides or front and back directions, ensuring that the shape of the entire triangular corbel does not undergo torsional deformation and maintaining the stability of the structure.

[0033] Each limiting groove 10 is respectively and movably clamped with each limiting block 13. A set of connecting grooves 14 are opened on the inner wall of each limiting groove 10. Each set of connecting grooves 14 are respectively and movably clamped with each set of limiting fins 15. The limiting fins 15 are made of cast iron material. Cast iron has a relatively high coefficient of friction and its surface is relatively rough. When the limiting fins 15 are inserted into the connecting grooves 14, the contact area between the fins and the groove walls increases. And due to their special shape, when bearing vertical loads, greater frictional forces can be generated. This frictional force is opposite to the direction of the vertical load, effectively preventing the inclined rod 2 and the vertical rod 3 from slipping on the cross bar 1. When the corbel bears relatively large construction loads or vertical pressures generated by its own weight, the frictional force can prevent relative sliding between the members, ensuring that the joint connection of the triangular corbel remains stable. The cooperation between the limiting fins 15 and the connecting grooves 14 provides an additional connection guarantee mechanism, increasing the redundancy of the structure. Even if there are certain degrees of defects or damages in the welded parts, the frictional force can still maintain the relative positions and connection stability between the members, providing a certain safety reserve for the structure. In extreme cases, such as when some welding points fail, the frictional force can temporarily bear part of the load, preventing the structure from collapsing immediately, providing time and conditions for repair or reinforcement, and further improving the reliability and safety of the triangular corbel under complex construction conditions.

[0034] Working principle:

[0035] First step, before the concrete pouring of the cross beam, the climbing cones 4 are accurately embedded according to the designed positions to provide an anchoring foundation for the subsequent corbel installation. After the cross beam is poured and the formwork is removed, the corbel installation begins. The corbel members (cross bar 1, inclined rod 2 and vertical rod 3) are connected by welding. The welds are full and the weld leg height is not less than 10 mm. The E43 type electrode is used for welding, and wind prevention measures are taken. The current is strictly controlled. Reinforcing blocks one 7, two 9 and three 11 are set at the joint positions for reinforcement to avoid stress concentration and ensure that the welds meet the stress requirements. The corbel is anchored to the concrete surface by means of the double climbing cones 4 at the position of the cross bar 1. Then the steps and railings are installed. The corbel structure is designed based on mechanical principles. The triangular structure composed of its members can effectively decompose and transfer the applied loads. The vertical loads are transmitted to the climbing cones 4 through the corbel members and then from the climbing cones 4 to the concrete structure, using the bearing capacity of the concrete structure to resist external forces. The climbing cones 4 are tightly connected to the corbel through their threaded structures to achieve a reliable anchoring effect. The detachable components such as the climbing cones 4 and the corbel can be reused, reducing the construction cost, providing a stable support point for the entire construction platform, preventing the corbel from slipping or being pulled out when bearing loads. The standardized design and installation methods make the construction process relatively simple, reducing the construction time and improving the construction efficiency. Through reasonable structural design and reinforcement measures, it can bear relatively large loads, providing stable support for the construction platform and ensuring construction safety and quality.

[0036] In the second step, the triangular web member structure formed by the second reinforcing plate 12 and the two first reinforcing plates 8 can effectively resist the deformation and distortion generated by the triangular corbel when bearing loads. When subjected to external forces, the first reinforcing plate 8 and the second reinforcing plate 12 will evenly disperse the forces to each member, avoiding stress concentration on a certain member or connection part, thereby improving the stability and load-bearing capacity of the entire triangular corbel structure. When there are large concentrated loads or dynamic loads on the construction platform, the triangular web member structure set can prevent the triangular corbel from undergoing instability failure. The connection of the two first reinforcing plates 8, the first reinforcing blocks 7, the two third reinforcing blocks 11, and the second reinforcing plate 12 forms an organic whole among the cross bar 1, the diagonal bar 2, and the vertical bar 3. This integrity enables the triangular corbel to work together during the force-bearing process, and the deformations among the members are coordinated with each other, improving the overall stiffness of the structure. Compared with the un-reinforced structure, under the action of the same load, its deformation is smaller, and it can better meet the requirements for structural accuracy and stability during the construction process.

[0037] In the third step, the shapes and sizes of the limiting block 13 and the limiting groove 10 match each other. This tight fit can limit the displacements of the diagonal bar 2 and the vertical bar 3 relative to the cross bar 1 in multiple directions. The depth and width of the limiting groove 10 are designed to be slightly larger than those of the limiting block 13, enabling the limiting block 13 to be smoothly inserted and clamped in the limiting groove 10, and there is almost no gap in the horizontal direction (including transverse and longitudinal directions), thereby effectively preventing the translation and rotation of the members in the horizontal direction. When the triangular corbel bears horizontal loads, such as wind force from the side or collision force during construction, the clamping of the limiting block 13 and the limiting groove 10 can prevent the diagonal bar 2 and the vertical bar 3 from moving to the sides or front and back directions, ensuring that the shape of the entire triangular corbel does not undergo torsional deformation and maintaining the stability of the structure. The limiting fin 15 is made of cast iron material, and cast iron has a relatively high friction coefficient and a relatively rough surface. When the limiting fin 15 is inserted into the connecting groove 14, the contact area between the fin and the groove wall increases, and due to its special shape, a greater frictional force can be generated when bearing vertical loads. This frictional force is opposite to the direction of the vertical load, effectively preventing the sliding tendency of the diagonal bar 2 and the vertical bar 3 on the cross bar 1. When the corbel bears a large construction load or the vertical pressure generated by its own weight, the frictional force can prevent relative sliding between the members, ensuring the stability of the node connection of the triangular corbel. The cooperation between the limiting fin 15 and the connecting groove 14 provides an additional connection guarantee mechanism, increasing the redundancy of the structure. Even if there are certain defects or damages in the welded parts, the frictional force can still maintain the relative positions and connection stability between the members, providing a certain safety reserve for the structure. In extreme cases, such as partial failure of the welded joints, the frictional force can temporarily bear part of the load, preventing the structure from collapsing immediately, providing time and conditions for repair or reinforcement, and further improving the reliability and safety of the triangular corbel under complex construction conditions.
