Description

Technical Field

[0001] This utility model relates to the field of building construction facilities technology, specifically to a scaffolding for column casting that can be hoisted as a whole. Background Technology

[0002] In the field of building construction, columns, as core components bearing the structural loads of buildings, directly affect the overall project progress through the quality and efficiency of their pouring. Scaffolding, as an indispensable and crucial auxiliary facility in column pouring operations, plays a vital role in providing a stable operating platform for construction workers and ensuring their safety, thus serving as a fundamental condition for ensuring the standardized implementation of pouring operations.

[0003] Currently, the scaffolding widely used in the industry for column casting is limited by structural design flaws. After the casting of a single column is completed, the entire structure cannot be stably hoisted and transferred. Because the layers of scaffolding are typically connected by interlocking sleeves, the connections are loose and the overall structural strength is insufficient. Forced hoisting can easily lead to safety accidents such as scaffold deformation and connector detachment. Therefore, the traditional one-column-one-scaffolding construction mode has to be adopted. This means that for each column casting location, the entire process of material transportation, component assembly, and safety protection setup must be completed from scratch. Only after the column casting is completed can the scaffolding be dismantled and materials removed. This traditional construction mode not only consumes a lot of manpower, resources, and time, increasing construction costs, but also poses certain safety hazards due to frequent erection and dismantling operations, and also affects the construction schedule. Utility Model Content

[0004] To overcome the problem that existing scaffolding for column casting cannot be hoisted as a whole, this utility model provides a column casting scaffolding that can be hoisted as a whole. This scaffolding can be hoisted to the next column casting position after the completion of one column casting, reducing the number of scaffolding erected, reducing construction costs, and improving construction efficiency.

[0005] The technical solution of this utility model is as follows:

[0006] A scaffold for column casting that can be hoisted as a whole includes several layers of vertically spliced ​​U-shaped construction platforms. Each U-shaped construction platform includes multiple columns arranged in a U-shape. Multiple vertically distributed horizontal bars are arranged between two adjacent columns in the horizontal direction. An upper connecting flange is provided at the upper end of each column, and a lower connecting flange that mates with the upper connecting flange is provided at the lower end of each column.

[0007] In the two adjacent U-shaped construction platforms, a connecting sleeve is provided inside between the upper column and the lower column. The upper and lower ends of the connecting sleeve are connected to the upper column and the lower column respectively by pins.

[0008] In a preferred embodiment of this utility model, in two adjacent U-shaped construction platforms, the lower connecting flange of the upper column is connected to the upper connecting flange of the lower column by bolts.

[0009] As a preferred embodiment of this utility model, the same side wall at both ends of the column is provided with a first upper pin hole and a first lower pin hole, respectively, and the same side wall at both ends of the connecting sleeve is provided with a second upper pin hole that mates with the first upper pin hole and a second lower pin hole that mates with the first lower pin hole, respectively.

[0010] As a preferred embodiment of this utility model, steel walkway slabs are laid between the uppermost horizontal bars of each layer of the U-shaped construction platform, and upper and lower entrances and exits are reserved.

[0011] As a preferred embodiment of this utility model, each of the U-shaped construction platforms is equipped with a steel staircase connecting the upper and lower entrances / exits.

[0012] As a preferred embodiment of this utility model, all the columns of the U-shaped construction platform located at the bottom are provided with support bases and fixed by steel wire binding.

[0013] As a preferred embodiment of this utility model, a diagonal tie rod is provided between two adjacent columns in the horizontal direction.

[0014] As a preferred embodiment of this utility model, the column is provided with a plurality of vertically distributed central connecting flanges in the middle, and both ends of the crossbar and the diagonal tie rod are provided with rod end fasteners, which are connected to the central connecting flanges by pins.

[0015] As a preferred embodiment of this utility model, the lower ends of all the columns of the U-shaped construction platform located at the bottom are connected to the first reinforcing steel pipe through steel pipe fasteners.

[0016] As a preferred embodiment of this utility model, the upper ends of all the columns of the U-shaped construction platform located at the top are connected to the second reinforcing steel pipe through steel pipe fasteners.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model provides a scaffold for column pouring that can be hoisted as a whole. The columns of adjacent U-shaped construction platforms are connected by flanges and bolts. The use of connecting sleeves and pins further enhances the connection strength between upper and lower columns, ensuring that they will not easily separate during hoisting and providing a reliable connection guarantee for overall hoisting. The support base is fixed with steel wire bindings to ensure that it will not detach from the column during hoisting, guaranteeing stable support at the bottom of the scaffold during the process. After completing the pouring of one column, the entire scaffold can be hoisted to the next column pouring location, avoiding the need to erect scaffolding from scratch for each column pouring location. This significantly reduces the number of scaffolds required, saves time on frequent scaffolding erection and dismantling, lowers construction costs, and improves construction efficiency.

[0031] Please see Figures 1 to 4This utility model provides a scaffold for column pouring that can be hoisted as a whole, comprising several layers of vertically spliced ​​U-shaped construction platforms 1. Each U-shaped construction platform 1 includes multiple columns 11 arranged in a U-shape, with multiple vertically distributed horizontal bars 12 positioned between adjacent columns 11 in the horizontal direction. The U-shaped construction platform 1 uses multiple U-shaped columns 11 as its main frame, combined with the horizontal bars 12, to form a closed U-shaped structure. This structure can evenly distribute construction loads and external forces, improving the overall deformation resistance and stability of the platform and providing a safe and reliable operating space for construction personnel. Simultaneously, the U-shaped structure can adapt to the pouring requirements of columns 11 with different cross-sectional dimensions. By adjusting the spacing of the columns 11 and the number of horizontal bars 12, it can meet the construction operations of various specifications of columns 11, improving the versatility and applicability of the scaffold.

[0032] The upper end of column 11 is provided with an upper connecting flange 111, and the lower end of column 11 is provided with a lower connecting flange 112 that mates with the upper connecting flange 111. In two adjacent U-shaped construction platforms 1, the lower connecting flange 112 of the upper column 11 is connected to the upper connecting flange 111 of the lower column 11 by bolts. The large contact area of ​​the flanges and the rigid fixing method of the bolts ensure the firmness of the connection between the two adjacent U-shaped construction platforms 1, effectively transmit vertical loads and horizontal forces, improve the overall structural rigidity of the scaffolding, and meet the strength requirements during overall hoisting. In addition, a connecting sleeve 2 is provided inside between the upper column 11 and the lower column 11. The upper and lower ends of the connecting sleeve 2 are connected to the upper column 11 and the lower column 11 respectively by pins. The inner connecting sleeve 2 and the outer upper connecting flange 111 and lower connecting flange 112 form an inner and outer double fixing structure, which further enhances the stability and safety of the column 11 connection, prevents the connection from loosening or falling off during hoisting and construction, and effectively avoids safety risks.

[0033] All the columns 11 of the bottom-shaped construction platform 1 are equipped with support bases 3, which provide a stable support foundation for the entire scaffold. The support bases 3 are fixed to the corresponding columns 11 by steel wire binding, which effectively prevents the support bases 3 from separating from the columns 11 during the overall hoisting and moving process, thus ensuring the integrity and stability of the overall scaffold structure.

[0034] The column pouring scaffolding in this embodiment can be hoisted as a whole to the next column 11 pouring position after the completion of one column 11 pouring position. This avoids the need to start scaffolding from scratch for each column 11 pouring position, greatly reducing the number of scaffolding to be erected, saving the time of frequent scaffolding erection and dismantling, reducing construction costs and improving construction efficiency.

[0035] In a preferred embodiment, the uprights are made of No. 60 steel pipes, with a length of 2m. No. 60 steel pipes possess high strength and good toughness, capable of withstanding the significant loads during the pouring of column 11, including the weight of construction personnel, equipment, and pouring materials. This ensures the structural stability of the scaffolding during overall hoisting and use, preventing deformation or breakage and thus guaranteeing construction safety. The 2m length of the uprights meets the height requirements for pouring column 11 while facilitating transportation and installation.

[0036] In a preferred embodiment, in two adjacent U-shaped construction platforms 1, the lower connecting flange 112 of the upper column 11 is connected to the upper connecting flange 111 of the lower column 11 by four M12 bolts. The M12 bolts have a large diameter and high strength, enabling them to resist shear forces. The four M12 bolts provide a large connection force, ensuring a firm and reliable connection between the upper and lower U-shaped construction platforms 1.

[0037] Please see Figure 3 , Figure 4 In a preferred embodiment, the same sidewall at both ends of the column 11 is provided with a first upper pin hole 113 and a first lower pin hole 114, respectively. The same sidewall at both ends of the connecting sleeve 2 is provided with a second upper pin hole 21 that mates with the first upper pin hole 113 and a second lower pin hole 22 that mates with the first lower pin hole 114, respectively. By providing corresponding pin holes, precise positioning and fixation can be achieved between the connecting sleeve 2 and the column 11. During installation, aligning the second upper pin hole 21 and the second lower pin hole 22 of the connecting sleeve 2 with the first upper pin hole 113 and the first lower pin hole 114 of the column 11, and then inserting the pins, ensures accurate relative positioning between the connecting sleeve 2 and the column 11, preventing offset and loosening during connection, and improving the stability and reliability of the connection.

[0038] Please see Figure 2 In a preferred embodiment, steel walkways 13 are laid between the uppermost horizontal bars 12 of each U-shaped construction platform 1, with reserved upper and lower entrances / exits 14. The steel walkways 13, laid between the horizontal bars 12, provide a flat and solid walking surface for construction workers, enabling them to work normally on each U-shaped construction platform 1. The reserved upper and lower entrances / exits 14 facilitate quick and orderly movement of construction workers between the U-shaped construction platforms 1. Furthermore, each U-shaped construction platform 1 is equipped with steel staircases 15 connecting the upper and lower entrances / exits 14, allowing construction workers to quickly and safely reach each U-shaped construction platform 1.

[0039] Please see Figure 1In a preferred embodiment, a diagonal brace 16 is also provided between two adjacent horizontal columns 11. The diagonal brace 16, together with the columns 11 and the horizontal bars 12, forms multiple triangular structures, which can effectively distribute and transfer the load borne by the scaffold, enhancing the deformation resistance and stability of the entire scaffold. When subjected to horizontal forces (such as wind force, lateral forces generated by construction operations, etc.), the diagonal brace 16 can provide additional tension to prevent the scaffold from tilting or twisting laterally.

[0040] Please see Figure 3 , Figure 5 , Figure 6 In a preferred embodiment, the column 11 has multiple vertically distributed central connecting flanges 115 at its center, providing a stable connection foundation for the connection between the crossbar 12 and the diagonal brace 16 and the column 11. Both ends of the crossbar 12 and the diagonal brace 16 are provided with end couplings 121, which are connected to the central connecting flanges 115 via pins. This connection method is simple to operate and provides a secure connection. The pins can be accurately inserted into the corresponding holes, enabling rapid positioning and fixing of the crossbar 12 and the diagonal brace 16 to the column 11. Simultaneously, the pins have strong shear resistance, effectively transferring loads and preventing relative displacement at the connection points.

[0041] Please see Figure 7 In a preferred embodiment, the lower ends of all the columns 11 of the bottom U-shaped construction platform 1 are connected to the first reinforcing steel pipe 4 via steel pipe couplers, and the upper ends of all the columns 11 of the top U-shaped construction platform 1 are connected to the second reinforcing steel pipe 5 via steel pipe couplers. This makes the entire scaffolding form a more compact and collaborative whole, allowing each part to work together better under external forces, thus improving the overall deformation resistance and load-bearing capacity of the scaffolding. Using steel pipe couplers is a common and standardized connection method that construction workers are familiar with and skilled at. This connection method does not require complex tools or special skills, and can quickly and easily connect the first and second reinforcing steel pipes 4 and 5 to the columns 11, improving construction and installation efficiency.
