Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a formwork-free structural column. Background Art

[0002] The traditional structural column is to build the wall to be built, and then support the formwork at the position of the structural column after completion, and then pour concrete. After the concrete solidifies and takes shape, the formwork is removed to form a complete structural column. The process of building and removing the formwork of the traditional structural column is time-consuming and labor-intensive, which prolongs the construction period. The commonly used structural column is to install the hollow prefabricated masonry panels at the position of the structural column, tie the steel bars and then pour concrete into the cavity of the prefabricated masonry panels to form a complete structural column, which reduces the process of building and removing the formwork, can effectively save construction time and improve construction efficiency.

[0003] The existing public patent (publication number CN 216195712 U) discloses a formwork-free structural column, including a first structural column block and a second structural column block installed at a reserved position on the wall to form a block with a receiving cavity, and the two ends of the first structural column block penetrated by the receiving cavity form a limit plate. A plurality of reinforcing steel bars are vertically placed in the receiving cavity of the pre-construction column, and the reinforcing steel bars are bundled by steel bar rings and elastic support columns. One end of the support column is connected to the steel bar ring, and the other end can be against the inner wall of the receiving cavity. The present application can effectively improve the problem of displacement of reinforcing steel bars caused by the concrete pouring process by abutting the end of the support column against the inner wall of the receiving cavity or the limit plate.

[0004] The above-mentioned structural column assembly method is complicated, and the overall structural strength is weak and the practicality is low. Therefore, the utility model proposes a formwork-free structural column to achieve improvement on the above-mentioned problem. Utility Model Content

[0005] The utility model aims to provide a formwork-free structural column to solve the problems of the existing formwork-free structural columns mentioned in the above background technology, namely, complicated installation, weak structural strength and low practicality.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a formwork-free structural column, comprising a plurality of structural column monomers for constructing the structural column, wherein the structural column monomers include symmetrically arranged outer formworks, vertical beams for fixing two outer formworks, an inner liner arranged in the inner cavity of the outer formwork, and a pad and a positioning block embedded between the side surface of the inner liner and the inner wall of the outer formwork.

[0007] Preferably, a steel bar hole is provided at the middle position of the inner side of the division of the outer formwork, and steel bars are inserted into the steel bar holes in the structural column monomer.

[0008] Preferably, a plurality of the structural column monomers are arranged vertically, and adjacent structural column monomers are connected via spacers.

[0009] Preferably, the cushion block and the positioning block are interlocked with each other, and the cushion block and the positioning block are symmetrically arranged about the center line of the inner liner.

[0010] Preferably, the middle portion of the positioning block is convex, and the two sides of the inner container are concave, and the convex portion in the middle portion of the positioning block matches the concave portion in the middle portion of the side of the inner container.

[0011] Preferably, the edge of the outer template is convex, and the convex edge is interlocked with the edge of the vertical beam.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model forms the outer structure of the structural column by arranging a plurality of structural column monomers and assembling them in sequence. The assembly method between adjacent structural column monomers is more stable than the current simple buckled structural column structure. At the same time, the multi-layer structure setting in the structural column monomer can also greatly improve the structural strength of the structural column monomer and avoid damage during the concrete pouring process.

[0014] During the assembly process, the height of the pad in the lowest structural column unit is greater than the height of the pad above it, but their cross-sectional shapes are the same. Therefore, when installing the structural column units one by one, the pad structure in the upper structural column unit will be higher than the upper side of the outer formwork, and the higher part is used for subsequent structural column unit position limiting, and the pad structure is used to limit the position between adjacent structural column units. After the overall assembly of the structural column is completed, the steel bars are inserted into the steel bar holes, and concrete is poured into the inner liner to complete the assembly and pouring of the formwork-free structural column.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] See also Figure 1-3 , in the figure: This embodiment is a preferred implementation of the technical solution, a formwork-free structural column, including a plurality of structural column monomers 1 for constructing the structural column, the structural column monomer 1 includes a symmetrically arranged outer template 11, a vertical beam 12 for fixing two outer templates 11, an inner liner 14 arranged in the inner cavity of the outer template 11, and a pad 13 and a positioning block 15 embedded between the side of the inner liner 14 and the inner wall of the outer template 11;

[0022] It should be noted that in the formwork-free structural column involved in the present application, a number of structural column monomers 1 are arranged and assembled in sequence to form the outer structure of the structural column. The assembly method between adjacent structural column monomers 1 is more stable than the current simple buckled structural column structure. At the same time, the multi-layer structure setting in the structural column monomer 1 can also greatly improve the structural strength of the structural column monomer 1 and avoid damage during the pouring of concrete. The separate external formwork 11 structure facilitates the construction needs of the structural column.

[0023] Several structural column monomers 1 are arranged vertically, and adjacent structural column monomers 1 are connected via pads 13; a steel bar hole 16 is provided at the middle position of the inner side of the outer template 11, and steel bars are inserted into the steel bar holes 16 in the structural column monomers 1;

[0024] It should be noted that when the structural column monomers 1 are in use, they are arranged and assembled vertically to form a structural column as a whole that does not require formwork, wherein the height of the pad 13 in the lowest structural column monomer 1 is greater than the height of the pad 13 above it, but their cross-sectional shapes are the same. Therefore, when the structural column monomers 1 are installed one by one, the pad 13 structures in the structural column monomers 1 located above will be higher than the upper side of the outer formwork 11, and the higher part is used for the subsequent position limitation of the structural column monomers 1, and the position limitation between adjacent structural column monomers 1 is realized by the pad 13 structure. After the overall assembly of the structural column is completed, the steel bars are inserted into the steel bar holes 16, and concrete is poured into the inner liner 14 to complete the assembly and pouring of the formwork-free structural column.

[0025] The cushion block 13 and the positioning block 15 are interlocked, and the cushion block 13 and the positioning block 15 are symmetrically arranged about the center line of the inner liner 14; the middle part of the positioning block 15 is convex, and the two sides of the inner liner 14 are concave, and the middle convexity of the positioning block 15 matches the concave middle part of the side of the inner liner 14;

[0026] It should be noted that the cushion block 13 and the positioning block 15 are both integrated structures with high structural stability. The protrusion at the end of the cushion block 13 cooperates with the depression at the end of the positioning block 15. The two interact with each other and keep the overall structure relatively fixed under the clamping action of the outer template 11 and the inner liner 14. The middle protrusion of the positioning block 15 cooperates with the middle depression on the side of the inner liner 14 to help fix the position of the inner liner 14. At the same time, the inner side bend of the middle protrusion of the positioning block 15 is equidistantly and continuously provided with vertical extensions to improve the physical strength of the bend.

[0027] The edge of the outer template 11 is convex, and the convex edge is interlocked with the edge of the vertical beam 12;

[0028] It should be noted that the outer formwork 11 is composed of two relatively arranged parts, which, under the fixing action of the vertical beam 12, form the outer formwork 11 structure in the structural column monomer 1, wherein the vertical beam 12 is interlocked with the edge of the outer formwork 11 in a snap-fitting manner, replacing the installation of fixed structures such as screws, making assembly more convenient and efficient.
