Description

Technical Field

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

[0002] In the process of modern building construction, reinforced concrete is often used as a load-bearing component, and masonry blocks are used to build infill walls to play a role of enclosure and separation. During the construction of masonry infill walls, in order to ensure the integrity of the wall, improve the shear bearing capacity of the masonry structure, and control the cracks of the masonry structure within a certain range, a structural column is usually set at a certain distance. The traditional construction process of structural columns is to tie steel bars, support formwork, pour concrete, and remove formwork. There are many construction steps and the process is cumbersome. In the process, material loss and waste are inevitable. In particular, the process of supporting and removing formwork must be constructed on site and cannot be prefabricated in advance, so it takes a lot of time. Utility Model Content

[0003] The purpose of the utility model is to overcome the above defects, optimize the steps of building structural columns, and provide a formwork-free structural column composite component.

[0004] To this end, the technical solution adopted by the utility model is as follows: a formwork-free structural column composite component, characterized in that it is composed of a plurality of first components, second components, third components, and fourth components, each of which includes a solid concrete block in a rectangular shape, the solid concrete block has three dimensions of width, height, and thickness, wherein two side surfaces in the thickness direction each have a wing plate, and the wing plates on the two side surfaces are mirror-symmetrical; the height of the wing plate is consistent with that of the solid concrete block and the width is greater than that of the solid concrete block, thereby forming a portion extending out of the solid concrete block; the portion of the wing plate extending out of the solid concrete block has at least two different widths at different positions in the height direction; the portion of the wing plate extending out of the solid concrete block has different thicknesses at its edges, thereby forming a step surface along its edge;

[0005] The solid concrete blocks of the first component and the second component have the same size, their widths in the height direction are complementary, and the step surfaces on the edges are also complementary, so that they can be spliced ​​together; the solid concrete blocks of the third component and the fourth component have the same size, their widths in the height direction are complementary, and the step surfaces on the edges are also complementary, so that they can be spliced ​​together; the solid concrete blocks of the first component and the third component have the same height and thickness, but different widths;

[0006] The first component and the second component are spliced ​​into a group, and the third component and the fourth component are spliced ​​into a group; in the height direction, the combination of the first component and the second component and the combination of the third component and the fourth component are staggered and overlapped to form a structural column.

[0007] Furthermore, each of the components also includes reinforcing steel bars, which are placed inside the solid concrete block and / or between the solid concrete block and the wing plate. The solid concrete block, the wing plate and the reinforcing steel bars are cast in one piece.

[0008] The use process of the utility model is to cast the required components in advance according to the design requirements; after starting the masonry, the structural column reinforcement is tied according to the preliminary layout diagram, and then the components are spliced. The bottom layer uses two wider components, such as the first component and the second component. After their edges are aligned, the rear wing plate just encloses the structural column reinforcement, and then the third and fourth components are spliced ​​on the upper layer, and so on until the entire structural column is assembled, and finally concrete is poured in the cavity left in the middle of the components.

[0009] It can be seen that according to the utility model, most of the work can be completed in advance off-site, and the structural columns can be constructed on the construction site in the manner of building blocks, without the need for formwork or dismantling formwork, which greatly improves the efficiency of casting the structural columns.

[0015] See also Figures 1 to 4 The first component includes a solid concrete block 1, a wing plate 2 and a reinforcing steel bar 3, which are cast in one piece, wherein the wing plate is wider than the solid concrete block and is divided into two sections, the upper section is wider than the lower section; the edge of the wing plate has different thicknesses to form a step surface 21. The wing plate of the second component has an upper section that is narrower than the lower section, and the step surface of the edge of the wing plate is in the opposite direction to that of the first component, so that the first component and the second component can be assembled with each other.

[0016] See also Figures 5 to 8. The first component, the second component, the third component, and the fourth component are marked as A, B, C, and D respectively. First, draw the corresponding masonry wall layout diagram according to the design drawing requirements and the actual site, clarify the size of the structural column and the required size of each component, and do a good job of customized production. After starting the masonry, according to the preliminary layout diagram, first tie the structural column steel bars 4. After the tying is completed, the masonry wall is built as shown in the figure. The structural column position is built with the combined components of this embodiment, and the wider A and B parts are used at the bottom for masonry, which meets the structural requirements of the structural column tooth joint to retreat first and then advance.

[0017] When laying bricks, pay attention to aligning the edges of A\B components to make them fit tightly, which can reduce the leakage problem that may occur during the later concrete pouring process and ensure the overall levelness and beauty of the masonry wall.

[0018] Continue to lay the upper layer of components according to the previous layout drawings. At this time, the narrower C and D components are used for masonry at the structural column position. When laying, it is also necessary to pay attention to aligning the edges of the C and D components so that they fit tightly. Repeat the above process until the entire masonry wall is completed, and pour concrete at the location where the structural column reinforcement 4 is tied.
