Description

Technical Field

[0001] The utility model relates to the technical field of house construction, in particular to a column steel frame structure for house construction. Background Art

[0002] Steel is characterized by high strength, light weight, good overall rigidity, and strong deformation capacity, so it is particularly suitable for building large-span, super-high, and super-heavy buildings; the material has good homogeneity and isotropy, and is an ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, can well withstand dynamic loads, has a short construction period, a high degree of industrialization, and can be produced with a high degree of mechanization; the column steel frame structure is mainly composed of columns and beams, and the common material is wide flange H-shaped steel. This structure forms a rigid frame through the combination of columns and beams to withstand and transmit various loads. The column steel frame structure for house construction plays an important role in modern architecture and is widely used in industrial and civil buildings;

[0003] The connection between the columns and beams of the existing column steel frame is generally installed and spliced ​​by welding. The high temperature generated during the welding process will form a heat-affected zone near the weld, and the metallographic structure and mechanical properties of the steel will change, causing the material to become brittle. In addition, the welding quality depends on the operating skills and experience of the welder. Different welders may produce different welding quality, which increases the risk of quality fluctuations to a certain extent. Once a problem occurs in the welded structure, repair and maintenance work is more difficult. At the same time, the non-detachable nature of the welded connection requires reheating and cooling during maintenance, which not only has a large workload, but may also introduce residual stress and deformation again. In view of this, we propose a column steel frame structure for house construction. Utility Model Content

[0020] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0021] The characteristics of steel are high strength, light weight, good overall rigidity and strong deformation ability, so it is particularly suitable for building large-span, super-high and super-heavy buildings; the material has good homogeneity and isotropy, and is an ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, can withstand dynamic loads well, has a short construction period, a high degree of industrialization, and can be produced with a high degree of mechanization; the column steel frame structure is mainly composed of columns and beams, and the common material is wide flange H-shaped steel. This structure forms a rigid frame through the combination of columns and beams to withstand and transmit various loads. The column steel frame structure for house construction plays an important role in modern architecture and is widely used in industrial and civil buildings.

[0022] See also Figure 1-Figure 4 As shown, the present embodiment provides a column steel frame structure for building construction, including a column steel frame body 1 and a steel beam body 2, the column steel frame body 1 and the steel beam body 2 are plugged together, considering that the column steel frame body 1 and the steel beam body 2 are generally connected by welding, different welders may produce different welding quality, which increases the risk of quality fluctuation to a certain extent. Once a problem occurs in the welding structure, repair and maintenance work is more difficult. At the same time, the non-detachable nature of the welded connection requires reheating and cooling during maintenance, which not only has a large workload, but also may introduce residual stress and deformation again. Therefore, the details are as follows: an insertion groove 20 is opened on the upper surface of the steel beam body 2, and movable grooves 21 are symmetrically opened on the upper surface of the steel beam body 2. The two movable grooves 21 are respectively arranged on both sides of the insertion groove 20 and are connected to the insertion groove 20;

[0023] The movable groove 21 has sliding grooves 210 on both sides of the inner wall, a limiting mechanism 3 is arranged inside the movable groove 21, the insertion groove 20 has mounting grooves 201 on both sides of the inner wall, a fixing mechanism 4 is installed inside the mounting groove 201, and the column steel frame body 1 has limiting grooves 10 on both sides.

[0024] The improvement of this embodiment is that:

[0025] Insert the column steel frame body 1 into the insertion groove 20 of the steel beam body 2, and connect the column steel frame body 1 to the steel beam body 2 through the limiting groove 10 and the limiting mechanism 3. The fixing mechanism 4 can further limit and fix the column steel frame body 1 to avoid welding, which is convenient for installation and disassembly, and easy for repair and maintenance.

[0026] Taking into account the installation and disassembly of the column steel frame body 1, a mounting plate 211 is arranged inside the movable groove 21, and the limiting mechanism 3 includes a support rod 30 and a limiting block 31. The end of the support rod 30 passes through the mounting plate 211, and a return spring 301 is arranged on the outer wall of the support rod 30, wherein: the top end of the return spring 301 is fixedly connected to the bottom end of the limiting block 31, and the bottom end of the return spring 301 is fixedly connected to the upper surface of the mounting plate 211. The mounting plate 211 and the limiting block 31 are respectively connected at both ends of the return spring 301, so that the support rod 30 drives the limiting block 31 to move forward and backward, and disengage from or enter the limiting groove 10.

[0027] A connecting plate 302 is installed at the bottom end of the support rod 30, and a slider 303 is installed on the outer wall of the connecting plate 302, wherein: the slider 303 is arranged inside the slide groove 210 and is slidably connected to the slide groove 210, and a grip block 304 is fixedly connected to the upper surface of the connecting plate 302. The user holds the grip block 304 to make the slider 303 slide inside the slide groove 210, driving the connecting plate 302 to move, thereby causing the support rod 30 to move forward and backward, driving the limit block 31 to move forward and backward, and disengaging from or entering the limit groove 10.

[0028] In order to further limit and fix the column steel frame body 1, a fixing mechanism 4 is provided, including an extrusion spring 40 and an extrusion block 41, wherein: the bottom end of the extrusion spring 40 is fixedly connected to the bottom end of the installation groove 201, and the top end of the extrusion spring 40 is fixedly connected to the bottom end of the extrusion block 41. By inserting the column steel frame body 1 into the insertion groove 20, the extrusion bottom end of the column steel frame body 1 is set to an arc-shaped extrusion block 41, and the extrusion spring 40 connected to the bottom end of the extrusion block 41 enters the installation groove 201. After the column bracket body is installed, the extrusion spring 40 will push the extrusion block 41 to squeeze the column steel frame body 1, thereby further limiting and fixing it.

[0029] In order to improve the local stability and bearing capacity of the column steel frame body 1, mounting frames 22 are symmetrically arranged on the lower surface of the steel beam body 2, and reinforcement plates 221 are hinged inside the two mounting frames 22. A connecting block 222 is installed at the bottom end of the reinforcement plate 221. A fixing groove 11 is opened on the surface of the column steel frame body 1, and connecting grooves 223 are opened on the surfaces of the two connecting blocks 222. The slot holes between the fixing groove 11 and the two connecting grooves 223 are on the same horizontal line. The connecting groove 223 and the fixing groove 11 are on the same horizontal line by rotating the reinforcement plate 221. Due to the threaded settings inside the fixing groove 11 and the connecting groove 223, screws are inserted to further support and fix the column steel frame body 1.

[0030] When the present invention is used in practice, the column steel frame structure for building construction is inserted into the insertion groove 20 of the steel beam body 2. The user holds the grip block 304 to make the slider 303 slide in the slide groove 210, driving the connecting plate 302 to move, so that the support rod 30 moves forward and backward, driving the limit block 31 to move forward and backward, and disengage from or enter the limit groove 10. After the grip block 304 is released, the return spring 301 provided on the outer wall of the support rod 30, which is respectively connected to the mounting plate 211 and the limit block 31, increases the elastic force of the limit block 31 to make it enter the limit groove 10, so that the column steel frame body 1 can be firmly connected with the steel beam body 2. When inserted into the groove 20, the column steel frame body 1 will squeeze the extrusion block 41 with an arc-shaped bottom end, and the extrusion spring 40 connected to the bottom end of the extrusion block 41 will enter the installation groove 201. After the column bracket body is installed, the extrusion spring 40 will push the extrusion block 41 to squeeze the column steel frame body 1, and further limit and fix it; after the column steel frame body 1 and the steel beam body 2 are installed, the reinforcement plate 221 is rotated to make the connecting groove 223 and the fixing groove 11 on the same horizontal line. Due to the threaded setting inside the fixing groove 11 and the connecting groove 223, the screws are inserted to further support and fix the column steel frame body 1, thereby improving the local stability and bearing capacity of the column steel frame body 1.
