Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and in particular to a prefabricated assembled support column. Background Technology

[0002] The primary function of supporting columns is to bear the weight of the roof and floors and transfer it to the foundation structure. In high-rise buildings, the role of supporting columns is particularly important; they must withstand greater weight and pressure to ensure the stability of the building. The shapes of these columns mainly include cylindrical, square, or polygonal prism-shaped columns.

[0003] In existing technologies, on-site construction requires tying a large number of steel bars to create a steel mesh framework in the shape of the column before pouring concrete. For columns with relatively complex shapes, formwork needs to be fixed to the outside of the steel mesh framework before pouring concrete. This results in high labor costs, slow construction speed, and the need for workers to erect a large amount of scaffolding when tying the steel mesh framework. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a prefabricated assembled support column, which can greatly reduce construction costs and speed up construction while ensuring the structural strength of the support column.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A prefabricated assembled support column includes: multiple column units stacked vertically, each column unit including an outer steel plate and a concrete pouring cavity; a guide connector is provided between two adjacent column units, the two ends of the guide connector extending into the concrete pouring cavities of the two adjacent column units respectively; a corresponding guide structure is provided between the guide connector and the inner wall of the outer steel plate; the guide connector and the outer steel plate are fixedly connected by bolts; the concrete pouring cavity is filled with concrete.

[0007] Preferably, the concrete pouring cavity is provided with transverse reinforcing connectors, and at least one pair of opposite outer steel plates are equipped with the transverse reinforcing connectors. The outer steel plates are provided with mounting holes for installing the transverse reinforcing connectors.

[0008] Preferably, auxiliary mounting blocks are fixed on the two opposite outer walls of the outer steel plate. Each auxiliary mounting block has a handle protrusion at both the upper and lower ends, and a hinge pin mounting hole is provided on the auxiliary mounting block.

[0009] Preferably, the guide structure includes a matching guide groove and a guide protrusion.

[0010] Preferably, the guide groove is formed on the guide connector, and the guide protrusion is disposed on the inner side of the outer steel plate.

[0011] Preferably, the outer steel plate is provided with a groove recessed into the concrete pouring cavity, the transverse reinforcing connector, the bolt and the auxiliary mounting block are located in the groove, and the guide structure is provided at the groove.

[0012] Preferably, the transverse reinforcing connector is a cylindrical steel rod.

[0013] Preferably, the transverse reinforcing connector is a steel bar.

[0014] Preferably, the column unit is a square column unit, and the outer steel plate structure on each side of the square is the same.

[0015] The beneficial effects of this utility model after adopting the above technical solution are as follows:

[0016] This utility model relates to a prefabricated assembled support column, comprising multiple stacked column units. Each column unit includes an outer steel plate and a concrete pouring cavity. Guide connectors are provided between adjacent column units, with both ends extending into the concrete pouring cavities of the two adjacent column units. Corresponding guide structures are provided between the guide connectors and the inner wall of the outer steel plate. The guide connectors and the outer steel plate are fixedly connected by bolts. The concrete pouring cavity is filled with concrete. The outer steel plate, guide connectors, and bolts of the column unit are all prefabricated in batches. The outer steel plate replaces the steel mesh framework, eliminating the need for on-site steel mesh tying, reducing on-site construction time and significantly lowering labor costs. The fixed connection between adjacent column units via guide connectors and bolts ensures reliable connection, structural stability, and convenient assembly and operation. The guide connectors not only serve as guides and connectors during installation, but also act as vertical reinforcing ribs, increasing the structural strength of the prefabricated assembled support columns and preventing the support columns from breaking off at the interface between the upper and lower column units due to the impact force during concrete pouring.

[0017] The concrete pouring cavity is equipped with transverse reinforcing connectors. At least one pair of opposing outer steel plates are fitted with these connectors, and mounting holes for the connectors are provided on the outer steel plates. The transverse reinforcing connectors can be cylindrical steel rods or reinforcing bars. The number of connectors can be selected based on the structural strength requirements of the specific design. After concrete is poured into the cavity, it bonds tightly with the transverse reinforcing connectors, further strengthening the structural strength of the precast assembled support column.

[0018] Auxiliary mounting blocks are fixed to the two opposite outer walls of the outer steel plate. Each auxiliary mounting block has a handle protrusion at both the top and bottom, and hinge pin mounting holes are provided. The auxiliary mounting blocks serve two purposes: firstly, they act as handles, facilitating the lifting of the column unit for assembling multiple column sections; secondly, they are used for hinged installation of auxiliary support rods, which provide temporary support and stability.

[0019] In summary, the prefabricated assembled support column provided by this utility model can greatly reduce construction costs and speed up construction while ensuring the structural strength of the support column. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] In the description of this utility model, it should be noted that the terms "front", "rear", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, while terms such as "first," "second," "third," etc., may be used in the text to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used in the text do not imply order or sequence.

[0030] like Figures 1 to 4 The prefabricated assembled support column shown includes multiple column units 1 stacked vertically. Each column unit 1 includes an outer steel plate 11 and a concrete pouring cavity 12. A guide connector 3 is provided between two adjacent column units 1. The two ends of the guide connector 3 extend into the concrete pouring cavity 12 of the two adjacent column units 1. A corresponding guide structure is provided between the guide connector 3 and the inner wall of the outer steel plate 11. The guide connector 3 and the outer steel plate 11 are fixedly connected by bolts (the bolts are hidden in the figure). Bolt holes S are correspondingly opened on the guide connector 3 and the outer steel plate 11. Concrete is poured and filled into the concrete pouring cavity 12.

[0031] In some embodiments, a transverse reinforcing connector 13 is provided inside the concrete pouring cavity 12, and the transverse reinforcing connector 13 is installed on at least one pair of opposing peripheral steel plates 11. The peripheral steel plates 11 are provided with mounting holes for installing the transverse reinforcing connector 13. For ease of processing, the mounting holes and bolt holes S can be set to the same specification.

[0032] like Figures 1 to 4 As shown, the bottommost column unit is defined as the first column unit, and the units above it are sequentially designated as the second column unit, the third column unit, and so on. The first column unit has transverse reinforcing connectors 13a installed on its front and rear outer steel plates, while the second column unit has transverse reinforcing connectors 13b installed on its left and right outer steel plates. Each column unit has one transverse reinforcing connector, and the directions of adjacent transverse reinforcing connectors are perpendicular in space. After concrete is poured into the concrete casting cavity, it tightly integrates with the transverse reinforcing connectors, further strengthening the structural strength of the prefabricated assembled support column.

[0033] Of course, the number of horizontal reinforcing connectors installed on each column unit can also be increased. For example, two or even more horizontal reinforcing connectors can be installed on the outer steel plate of each column unit. Multiple horizontal reinforcing connectors should be installed vertically in space as much as possible, and not all installed in the same direction to avoid uneven structural strength.

[0034] In some embodiments, such as Figure 2 , Figure 3 and Figure 5 As shown, auxiliary mounting blocks 14 are fixed on the two opposite outer walls of the outer steel plate 11. Each auxiliary mounting block 14 has a handle protrusion 141 at both its upper and lower ends, and a hinge pin mounting hole 142 is provided on the auxiliary mounting block 14. The hinge pin mounting hole 142 is used to hinge the auxiliary support rod 4 via a pin. The auxiliary mounting blocks serve two purposes: firstly, they act as handles, facilitating the lifting of the column unit for assembling multiple column units; secondly, they are used to hinge the auxiliary support rod 4, which provides temporary support and stability. The auxiliary support rod 4 can be removed after the concrete in the concrete pouring cavity has solidified, at which point the prefabricated assembled support column is stable. Removing the auxiliary support rod 4 allows for subsequent finishing and decoration of the support column surface using concrete or other materials.

[0035] In some embodiments, the guide structure includes a matching guide groove 51 and a guide protrusion 52. The guide groove 51 is formed on the guide connector 3, and the guide protrusion 52 is disposed on the inner side of the outer steel plate 11. Alternatively, the guide groove can be formed on the inner side of the outer steel plate 11, and the guide protrusion can be disposed on the guide connector 3.

[0036] In some embodiments, the outer steel plate 11 is provided with a groove 110 recessed into the concrete pouring cavity 12. The transverse reinforcing connector 13, bolts, and auxiliary mounting blocks 14 are located within the groove 110, and a guide structure is also provided within the groove 110. The protruding positions of the transverse reinforcing connector 13, bolts, and auxiliary mounting blocks 14 do not exceed the depth of the groove 110. For the aesthetic purposes of the building and to avoid the impact of components under construction on subsequent decoration work, bolts or other protruding components are generally covered with concrete during later repairs. When covering these protrusions with concrete, only the groove 110 needs to be heavily covered; a shallower layer can be used for the remaining areas. The groove 110 significantly reduces the amount of concrete used during finishing.

[0037] In some embodiments, the transverse reinforcing connector 13 is a cylindrical steel rod. Alternatively, the transverse reinforcing connector 13 may be a reinforcing bar.

[0038] In some embodiments, the column unit 1 is a square column unit, and the outer steel plate 11 on each side of the square has the same structure. When the column unit is set as a square, it is not necessary to specifically distinguish the front, back, left, and right of each column unit when stacking and assembling them, which is convenient for processing and assembly. Figure 1As shown, the auxiliary mounting blocks 14 on two adjacent upper and lower column units can be oriented in the same direction, i.e., both in the left and right directions, as needed. Alternatively, they can be oriented in different directions; for example, the auxiliary mounting blocks on the first column unit can be in the left and right directions, while the auxiliary mounting blocks on the second column unit can be in the front and rear directions. This allows for flexible selection of the installation direction of the auxiliary support rod 4 as needed.

[0039] The outer steel plate 11, guide connector 3, transverse reinforcing connector 13, and bolts of the column unit are all prefabricated in batches. After being prefabricated in the factory, these components are transported to the construction site and then assembled. Concrete is then poured into the concrete pouring cavity 12. After the concrete solidifies, it is tightly connected to the above components to form the supporting column. This supporting column has the characteristics of high load-bearing capacity, high rigidity, good seismic performance, and good dynamic performance. The outer steel plate 11 replaces the steel mesh skeleton, eliminating the need to tie the steel mesh skeleton on the construction site, reducing on-site construction time and significantly lowering labor costs. The two adjacent column units are fixedly connected by the guide connector 3 and bolts, which not only ensures reliable connection and structural stability but also facilitates assembly and operation. The guide connector 3 not only serves as a guide and connection during installation but also acts as a vertical reinforcing rib, increasing the structural strength of the prefabricated assembled supporting column and preventing the supporting column from breaking at the interface between the upper and lower column units due to the impact force during concrete pouring.

[0040] In addition, it has the advantages of saving formwork and scaffolding, facilitating construction, improving construction efficiency, and shortening the construction period.

[0041] In summary, the prefabricated assembled support column provided by this utility model can greatly reduce construction costs and speed up construction while ensuring the structural strength of the support column.

[0042] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
