Description

Technical Field

[0001] This utility model belongs to the technical field of building construction, and in particular relates to a light steel house composite beam and column forming device. Background Technology

[0002] Steel-concrete composite columns in light steel frame housing construction are structural components formed by combining steel (such as structural steel sections and steel pipes) with concrete, combining the high strength of steel with the durability of concrete. The core principle is that the steel bears the main tensile stress, while the concrete resists compressive stress. Working together, they effectively improve the load-bearing capacity, seismic performance, and stiffness of the component. For example, in self-built houses, these composite columns can be used in spaces with large spans or in areas requiring enhanced structural stability. They can reduce the column cross-sectional dimensions, increase usable area, and adapt to complex load conditions, providing more reliable support for the house. However, during construction, attention must be paid to the bonding process between the steel and concrete to ensure that both share the load and fully realize the structural advantages of the composite column.

[0003] However, it still has the following drawbacks in actual use: uneven concrete pouring is very likely to occur during the concrete pouring process. Due to the nature of concrete itself, it is mainly composed of stone and mortar. Due to the weight of the stone itself and the fluid nature of the mortar, it is easy for all the stones to sink to the bottom after pouring, while there is mostly only mortar on top. This results in the concrete structure above being unstable, which is especially obvious in the pouring of column-shaped buildings. Utility Model Content

[0004] The purpose of this utility model is to provide a composite beam and column forming device for light steel houses. This utility model solves the problem of uneven concrete pouring in the existing composite column by setting up support components and mixing components.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a composite beam and column forming device for light steel houses, including a support component and a mixing component. The support component includes a base, an outer column is fixed on the top of the base, a crossbeam connector is fixed on the top of the outer periphery of the outer column, and an end cap is provided on the end of the outer column away from the base.

[0007] The mixing assembly includes an inner cylinder fixed to the center of the inner cavity of the outer column. The bottom of the inner cylinder has a bottom hole, and the outer periphery of the inner cylinder has a material passage hole. A spiral blade is also rotatably connected to the bottom of the inner cylinder. A support frame is provided on the outer periphery of the outer column. The mixing assembly includes a flange. The outer column and the support frame are fixedly connected by the flange and matching bolts. A motor and a reduction gearbox are fixed on the support frame. The mixing assembly also includes couplings. The motor, reduction gearbox and spiral blade central shaft are connected in sequence by two couplings.

[0008] Furthermore, several support plates are fixed at the connection between the base and the outer column, and the support plates are arranged in a ring array with the outer column as the center.

[0009] Furthermore, four crossbeam connectors are provided, and the four crossbeam connectors are arranged in a circular array with the outer column as the center.

[0010] Furthermore, the support assembly also includes stirrups fixed between the outer column and the inner cylinder, and multiple stirrups are provided.

[0011] Furthermore, multiple bottom holes are provided, and four sets of material passage holes are provided from bottom to top. The inner diameter of the material passage holes increases sequentially from bottom to top, and the number of material passage holes also increases sequentially from bottom to top.

[0012] Furthermore, the top of the inner cylinder is lower than the top of the outer column.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, through the setting of a support component and a mixing component, is fixed to the pile foundation driven into the ground during use. Concrete is poured into the outer column, and then the support frame, along with the motor and reduction gearbox on it, is installed onto the entire device. The motor is then started to drive the spiral blade to rotate, gradually carrying the concrete at the bottom away from the bottom end and moving upward along the spiral blade, thereby evenly dispersing the stones in the concrete. This solves the problem of uneven concrete pouring in existing composite column pouring solutions.

[0015] 2. This utility model, through the setting of a mixing component, has multiple sets of material passage holes. The inner diameter of the material passage holes increases sequentially from bottom to top, and the number of material passage holes also increases sequentially from bottom to top. Multiple bottom holes can increase the flow of concrete from the outer column to the inner cylinder. The material passage holes are used to assist the concrete to flow out from the outer column, which allows more concrete to flow out from a higher position, ultimately achieving uniform concrete distribution and further optimizing the problem of uneven concrete pouring that may occur in the above scheme.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-5 As shown, this utility model is a light steel house composite beam and column forming device, including a support component 1 and a mixing component 2. The support component 1 includes a base 11, an outer column 12 is fixed on the top of the base 11, and a crossbeam connector 14 is also fixed on the upper outer periphery of the outer column 12. An end cap 16 is provided at the end of the outer column 12 away from the base 11. The support component 1 is used to support the foundation column of the house. Its own structure is a precast component. After the concrete is poured, it is directly connected to it to form a steel-concrete composite column. The base 11 is the pile foundation of the foundation building, and its outer end is also provided with steel bars connected to the composite column.

[0026] The outer column 12 can be directly formed by pouring concrete inside to form the base column supporting the house. The crossbeam connector 14 is used for the fixed connection of the roof beam. The light steel structure roof beam is used to support the roof. The end cap 16 can seal the end cap 16 after the entire device is installed, increasing its aesthetics.

[0027] The mixing assembly 2 includes an inner cylinder 21 fixed to the center of the inner cavity of the outer column 12. The bottom end of the inner cylinder 21 has a bottom hole 22 and a material passage hole 23 on the outer periphery of the inner cylinder 21. The bottom end of the inner cylinder 21 is also rotatably connected to a spiral blade 24. A support frame 25 is provided on the outer periphery of the outer column 12. The mixing assembly 2 includes a flange 251. The outer column 12 and the support frame 25 are fixedly connected by the flange 251 and the matching bolts. A motor 26 and a reduction gearbox 261 are fixed on the support frame 25. The mixing assembly 2 also includes a coupling 262. The central shaft of the motor 26, the reduction gearbox 261 and the spiral blade 24 are connected in sequence by two couplings 262.

[0028] The bottom hole 22 allows concrete from the bottom of the outer column 12 to enter and then move upward under the action of the spiral blade 24. The material passage hole 23 allows concrete from the inner cylinder 21 to flow out and be evenly distributed to all parts of the outer column 12. The support frame 25 is used to fix the motor 26 and the reduction gearbox 261, so that they are stably fixed on the outer column 12. It is connected to the outer column 12 by flange 251 and bolts. The coupling 262 is used to connect the motor 26, the reduction gearbox 261 and the central shaft of the spiral blade 24, so as to facilitate docking and subsequent disassembly.

[0029] Furthermore, several support plates 13 are fixed at the connection between the base 11 and the outer column 12. The support plates 13 are arranged in a circular array with the outer column 12 as the center. Multiple support plates 13 are provided, which can improve the stability of the outer column 12 and the base 11 and increase the contact area of ​​the fixation. At the same time, the roughly triangular design of the appearance can further improve its stability.

[0030] Furthermore, four beam connectors 14 are provided, and the four beam connectors 14 are arranged in a circular array with the outer column 12 as the center. The connectors are used to connect with the light steel beams to realize the construction of the roof foundation structure.

[0031] Furthermore, the support component 1 also includes stirrups 15 fixed between the outer column 12 and the inner cylinder 21, and multiple stirrups 15 are provided. The stirrups 15 and concrete work together to form a reinforced concrete composite material, which increases the stability of the building.

[0032] Furthermore, multiple bottom holes 22 are provided, and four sets of material passage holes 23 are provided from bottom to top. The inner diameter of the material passage holes 23 increases from bottom to top, and the number of material passage holes 23 also increases from bottom to top. Multiple bottom holes 22 can increase the efficiency of concrete flowing from the outer column 12 into the inner cylinder 21 and prevent blockage. The material passage holes 23 are used to assist concrete in flowing out from the outer column 12. There are four sets of material passage holes 23. The first set has only one small and low hole, and only a small amount of concrete can flow out from inside because the first set is the lowest and closest to the bottom surface. Then, the number of material passage holes 23 increases from bottom to top, and the inner diameter of the holes increases from bottom to top. This allows more concrete to flow out from a higher position, ultimately achieving uniform distribution of concrete.

[0033] Furthermore, the top of the inner cylinder 21 is lower than the top of the outer column 12. Due to the nature of concrete itself, which is mainly composed of slurry and aggregate, the multiple sets of material passages 23 cannot completely and evenly disperse it. A large portion will be carried to the top of the inner cylinder 21 by the spiral blade 24, and then flow from the top of the inner cylinder 21 into the outer column 12, repeating the cycle until the concrete is evenly distributed in the outer column 12, thereby improving its stability. After the concrete is evenly dispersed, the motor 26 and the reduction gearbox 261 are removed, and the end cover 16 is put on. The spiral blade 24 flows into it, and its structure is more conducive to dispersing the concrete more evenly throughout the column. At the same time, the steel material inside better forms a steel-concrete composite column, increasing its stability.

[0034] The specific working principle of this utility model is as follows: When using the device, it is fixed to the pile foundation driven into the ground, referred to as base 11 in this article. Then, concrete is poured into the outer column 12. After the concrete is poured, the support frame 25, along with the motor 26 and reduction gearbox 261 on it, is installed onto the entire device. Then, the motor 26 is started to drive the spiral blade 24 to rotate, gradually carrying the concrete at the bottom away from the bottom and moving upward along the spiral blade 24, thereby evenly dispersing the stones in the concrete. The device has four sets of material passage holes 23 from bottom to top, and the inner diameter of the material passage holes 23 is from bottom to top. The number of material passage holes 23 increases sequentially from bottom to top. Multiple bottom holes 22 can increase the flow of concrete from the outer column 12 into the inner cylinder 21. The material passage holes 23 are used to assist the concrete to flow out from the outer column 12. There are four sets of material passage holes 23. The first set has only one small and low hole, and only a small amount of concrete can flow out from inside because the first set is the lowest and closest to the bottom surface. Then the number of material passage holes 23 increases sequentially from bottom to top, and the inner diameter of the holes increases sequentially. This allows more concrete to flow out from a higher position, ultimately achieving uniform distribution of concrete.

[0035] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall be protected by the present utility model.
