[0001] The utility model relates to the technical field of passive houses, in particular to an assembled steel structure passive house. Background Technique

[0002] The assembled steel structure passive house is a new system that combines the technologies of prefabricated buildings and passive ultra-low energy consumption buildings. This kind of residential building not only has the advantages of light weight, high strength, large span and flexible plane layout of steel structure buildings, but also through the adoption of passive design, it can minimize the demand for building heating and cooling, utilize renewable energy, achieve less energy consumption, and provide a comfortable indoor environment.

[0003] However, in the current prior art, when installing a steel structure passive house, it is first necessary to install the support columns and the foundation pits to form the foundation. However, when pouring the foundation, in order to increase the adhesion between the support columns and the concrete, bumps will be added to the support columns to improve the adhesion. However, the setting of the bumps may block the concrete during the concrete pouring, resulting in the obstruction of the concrete flow and causing cavity conditions, which will affect the strength of the foundation. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an assembled steel structure passive house to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An assembled steel structure passive house, including a foundation column, an auxiliary component for increasing the bonding surface with concrete is arranged inside the foundation column. The auxiliary component includes inclined platforms arranged on multiple outer walls of the foundation column. Orifice grooves are arranged on the outer walls of the multiple inclined platforms, cavities are arranged on the inner walls of the multiple orifice grooves, air bags are arranged inside the cavities, convex rods are arranged inside the multiple orifice grooves, a piston is arranged at one end of the convex rod, multiple positioning grooves are arranged on the outer wall of the convex rod, extension blocks are arranged inside the multiple positioning grooves, a through groove is arranged inside the foundation column, and a heat conduction plate is arranged on the inner wall of the through groove.

[0007] As a preferred scheme of the utility model, the multiple inclined platforms are all conical structures, are annularly distributed on the surface of the outer wall of the foundation column, and are integrally formed with the outer wall of the foundation column.

[0008] As a preferred scheme of the utility model, the multiple orifice grooves are all communicated with the internal cavities, the air bags are located inside the cavities and are adhesively connected to the inner walls of the cavities, and alcohol is loaded inside the air bags.

[0009] As a preferred solution of the present utility model, the convex rod is located inside the hole groove and is slidably connected to the inner wall of the hole groove through a slide rail. One end of the convex rod close to the hole groove is connected to the piston by a bolt, and the other end is of an arc structure.

[0010] As a preferred solution of the present utility model, a plurality of the positioning grooves are annularly distributed on the outer wall of the convex rod. The extension block is located inside the positioning groove and is rotatably connected to the inner wall of the positioning groove through a spring shaft.

[0011] As a preferred solution of the present utility model, the heat conduction plate is inlaid and connected with the inner wall of the through groove and is communicated with the cavity. The position of the through groove inside the foundation column corresponds to the inclined platform, and it is of a conical structure and is communicated with the top of the foundation column. The inside of the through groove is filled with cement powder.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: In response to the problems raised in the background art, this application adopts an auxiliary component. The inclined platform at the bottom of the foundation column increases the contact surface during concrete pouring and increases the gravity at the bottom of the foundation column, improving the stability of the foundation column. After the concrete is poured, water is injected into the through groove through the hole in the foundation column and reacts with the cement powder in the through groove to generate high temperature. At the same time, the high temperature is conducted to the airbag inside the foundation column. The alcohol in the airbag is heated by the high temperature to cause the alcohol to expand. The expansion acts on the piston and pushes the convex rod out of the inclined platform and into the poured concrete. The adhesion between the concrete and the foundation column after pouring is increased by the inclined platform and the convex rod fitting with the concrete, improving the stability of the foundation. And the hidden convex rod ensures the flow and dispersion of the concrete during concrete pouring.

[0013] The present utility model ensures the smooth dispersion of the concrete after pouring through the hidden convex block, and pushes the convex rod out through high temperature. The contact surface between the foundation column and the concrete is increased by the cooperation of the convex rod and the inclined platform, and the adhesion of the foundation column and the stability after pouring are improved.

[0019] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described.

[0020] Embodiment

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a prefabricated steel structure passive house, including a foundation column 1. An auxiliary component for increasing the bonding surface with concrete is arranged inside the foundation column 1. The auxiliary component includes inclined platforms 2 arranged on multiple outer walls of the foundation column 1. The inclined platforms 2 make the bottom of the foundation column 1 protrude, thereby increasing the inclined surface of the foundation column 1 and improving the contact surface after concrete pouring. Hole grooves 3 are arranged on the outer walls of the multiple inclined platforms 2 for storing and hiding the convex rods 4. Cavities 301 are arranged on the inner walls of the multiple hole grooves 3. An airbag 302 is arranged inside the cavity 301. Alcohol is loaded inside the airbag 302 (the alcohol will expand when heated, and the convex rod 4 will be pushed by the expansion of the airbag 302 to slide out in the hole groove 3), and it is adhesively attached to the temperature conduction plate 7. Convex rods 4 are arranged inside the multiple hole grooves 3. After the convex rods 4 extend out of the inclined platforms 2, they can be embedded into the concrete in the pouring groove, increasing the contact surface between the foundation column 1 and the concrete and improving the adhesion between the foundation column 1 and the concrete. A piston 401 is arranged at one end of the convex rod 4. Multiple positioning grooves 402 are arranged on the outer wall of the convex rod 4 for retracting the extension blocks 5. Extension blocks 5 are arranged inside the multiple positioning grooves 402. After the convex rod 4 extends out, the extension blocks 5 can rotate out of the positioning grooves 402 through the spring shafts and assist in embedding into the concrete. A through groove 6 is arranged inside the foundation column 1. Cement powder is loaded in the through groove 6, and water is injected into the through groove 6 after concrete pouring. Mixing with the cement powder can generate high temperature (and increase the gravity at the bottom of the foundation column 1 after the cement powder is mixed with water, increasing the stability of the foundation column 1), and the through groove 6 is of a conical structure to prevent high-temperature leakage. A temperature conduction plate 7 is arranged on the inner wall of the through groove 6. The temperature conduction plate 7 can conduct the high temperature after the reaction of the cement powder to the airbag 302 inside the cavity 301.

[0022] In this embodiment, all electrical components are controlled by a conventional controller.

[0023] Embodiment, please refer to Figures 1-4, multiple said inclined platforms 2 are all conical structures and are annularly distributed on the outer wall surface of the foundation column 1 and integrally formed with the outer wall of the foundation column 1. Multiple said holes 3 communicate with the internal cavity 301. The airbag 302 is located in the cavity 301 and adhesively connected to the inner wall of the cavity 301. Alcohol is loaded inside the airbag 302. The convex rod 4 is located in the hole 3 and is slidably connected to the inner wall of the hole 3 through a slide rail. One end of the convex rod 4 close to the hole 3 is connected to the piston 401 by a bolt, and the other end is an arc structure. Multiple said positioning grooves 402 are annularly distributed on the outer wall of the convex rod 4. The extension block 5 is located in the positioning groove 402 and is rotatably connected to the inner wall of the positioning groove 402 through a spring shaft. The heat conduction plate 7 is inlaid and connected with the inner wall of the through groove 6 and communicates with the cavity 301. The position of the through groove 6 inside the foundation column 1 corresponds to the inclined platform 2, and it is a conical structure and communicates with the top of the foundation column 1. Cement powder is loaded inside the through groove 6. During use, first place the foundation column 1 into the pouring groove, then pour concrete into the pouring groove. When the concrete is not solidified, inject water into the through groove 6 through the hole at the top of the foundation column 1. The water mixes with the cement powder in the through groove 6 to react and generate high temperature. The high temperature is conducted to the airbag 302 in the cavity 301 through the heat conduction plate 7. The alcohol in the airbag 302 is heated by the high temperature to expand, and the convex rod 4 is pushed to slide and extend out into the concrete in the pouring groove. When the convex rod 4 extends out, the extension block 5 is driven to rotate and extend out from the positioning groove 402 by the acting force of the spring shaft. The contact surface with the concrete is increased through the inclined platform 2 and the extended convex rod 4, improving the adhesion of the foundation column 1 and the stability of the foundation.

[0024] The working process of the present utility model: During use, first place the foundation column 1 into the pouring groove, then pour concrete into the pouring groove. When the concrete is not solidified, inject water into the through groove 6 through the hole at the top of the foundation column 1. The water mixes with the cement powder in the through groove 6 to react and generate high temperature. The high temperature is conducted to the airbag 302 in the cavity 301 through the heat conduction plate 7. The alcohol in the airbag 302 is heated by the high temperature to expand, and the convex rod 4 is pushed to slide and extend out into the concrete in the pouring groove. When the convex rod 4 extends out, the extension block 5 is driven to rotate and extend out from the positioning groove 402 by the acting force of the spring shaft. The contact surface with the concrete is increased through the inclined platform 2 and the extended convex rod 4, improving the adhesion of the foundation column 1 and the stability of the foundation. The present utility model ensures the smooth dispersion of the concrete after pouring through the hidden convex blocks, and pushes the convex rod to extend out through high temperature. The contact surface between the foundation column and the concrete is increased by cooperating with the convex rod and the inclined platform, and the adhesion of the foundation column and the stability after pouring are improved.
