Description

Technical Field

[0001] The utility model relates to the technical field of steel structure protection for residential buildings, and particularly relates to a steel column cladding node of a steel structure in a residential building. Background Technique

[0002] Steel structure buildings are a new type of building system. Compared with traditional concrete buildings, steel plates or steel sections are used to replace reinforced concrete, with higher strength and better seismic resistance. Their application in building fields such as high-rise residential buildings and super high-rise residential buildings is becoming increasingly mature and gradually becoming the mainstream building technology. In steel structure residential buildings, fire protection performance is an important performance index. Therefore, fire protection components are usually wrapped outside the steel columns to improve their fire resistance and high-temperature resistance. As shown in the existing patent technology: After retrieval, the Chinese Patent Network discloses a steel column cladding node in a steel structure residential building (publication announcement number CN205663054U). Such a device welds light steel keels around the indoor steel column and uses self-tapping screws to fixedly connect fireproof boards on the light steel keels, so that the fireproof boards form a cladding around the indoor steel column to obtain good fire protection performance and effectively solve the problem of the short fire resistance limit of the steel column.

[0003] However, for the cladding nodes of building steel structures adopted in the above-mentioned public patents and the existing market, there are still some deficiencies: The existing method uses keels as installation components and then circumferentially installs and wraps fireproof boards outside the building steel column in sequence. It requires welding the keels on the steel column in advance to make the keels as installation nodes, and then the fireproof boards can be wrapped and fixed on the steel column one by one. This is not only cumbersome in operation but also has a high operation intensity, time-consuming and laborious in installation, and extremely likely to increase the labor intensity of workers. Therefore, technical personnel in this field provide a steel column cladding node of a steel structure in a residential building to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a steel column cladding node of a steel structure in a residential building, which can effectively solve the problem that the installation of the existing building steel cladding node is relatively cumbersome in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: A steel column cladding node of a steel structure in a residential building, including a steel column body;

[0006] A first cladding component is sleeved on one side of the column body of the steel column body, and a second cladding component opposite to the first cladding component is sleeved on the other side of the column body of the steel column body. The first cladding component and the second cladding component are screwed and fixed through multiple groups of positioning screws arranged in a pairwise symmetric manner;

[0007] The first covering component includes a first fireproof board frame, and the butting edges of the frame of the first fireproof board frame are provided with butting clamping strips;

[0008] The second covering component includes a second fireproof board frame, and the butting edges of the frame of the second fireproof board frame are provided with butting clamping grooves.

[0009] As a further scheme of the present utility model: both the first covering component and the second covering component are in a U-shaped structure.

[0010] As a further scheme of the present utility model: the outer diameter of the pressing strip of the butting clamping strip is adapted to the inner diameter of the groove body of the butting clamping groove, and the first fireproof board frame and the second fireproof board frame are butted and closed through the butting clamping strip and the butting clamping groove.

[0011] As a further scheme of the present utility model: on both sides of the frame of the first fireproof board frame, a plurality of groups of first positioning screw holes penetrating through the butting clamping strip are arranged in a pairwise symmetric form, on both sides of the frame of the second fireproof board frame, a plurality of groups of second positioning screw holes opposite to the butting clamping groove are arranged in a pairwise symmetric form, the first positioning screw holes and the second positioning screw holes are aligned with each other, and the butting ends of the first positioning screw holes and the second positioning screw holes are adapted to the positioning screw rod.

[0012] As a further scheme of the present utility model: the bottom of the frame of the first fireproof board frame is provided with a first flange, and the top of the frame of the first fireproof board frame is provided with a first groove having the same size as the first flange.

[0013] As a further scheme of the present utility model: the bottom of the frame of the second fireproof board frame is provided with a second flange, and the top of the frame of the second fireproof board frame is provided with a second groove having the same size as the second flange.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] When the present utility model covers and protects the steel column of the building steel, by using the left and right butting sleeves of the first covering component and the second covering component to perform fireproof covering on the exposed part of the steel column, and using the bolt fastening of the positioning screw rod, the overall structure of the covering node can be fixedly installed. It can be installed without the aid of external components. While the operation is simple, convenient and efficient, it is also convenient for subsequent disassembly, repair and recycling operations. Moreover, by using the butting of the grooves and flanges at the upper and lower ends of the two groups of covering components, they can be installed one by one in a way of assembling sequentially from top to bottom, reducing the overall installation strength while improving the installation efficiency.

Both the first cladding component 2 and the second cladding component 3 are in a U-shaped structure. Based on the clamping of the first cladding component 2 and the second cladding component 3 of the two U-shaped structures, they can be clamped on the outside of the steel column body 1 in a way of mating and sleeving to form a square-structured cladding protection.

[0025] The first cladding component 2 includes a first fireproof board frame 21, and a pair of pressure clamping strips 22 are arranged on the mating frame edges of the first fireproof board frame 21. The second cladding component 3 includes a second fireproof board frame 31, and a pair of pressure clamping grooves 32 are opened on the mating frame edges of the second fireproof board frame 31. The outer diameter of the pressure strip of the pressure clamping strip 22 is adapted to the inner diameter of the groove body of the pressure clamping groove 32. The first fireproof board frame 21 and the second fireproof board frame 31 are closed by mating the pressure clamping strip 22 and the pressure clamping groove 32. When the first cladding component 2 and the second cladding component 3 are clamped, by using the mating closure of the pressure clamping strip 22 and the pressure clamping groove 32, the cladding tightness of the two cladding components can be improved, the influence of the existence of gaps can be reduced, and the installation accuracy of the two cladding components can be improved at the same time.

[0026] The first cladding component 2 and the second cladding component 3 are fixedly connected by screwing a plurality of groups of positioning screws 4 arranged in a pairwise symmetric manner. A plurality of groups of first positioning screw holes 23 penetrating the pressure clamping strip 22 are opened on both sides of the frame of the first fireproof board frame 21 in a pairwise symmetric form. A plurality of groups of second positioning screw holes 33 opposite to the pressure clamping groove 32 are opened on both sides of the frame of the second fireproof board frame 31 in a pairwise symmetric form. The first positioning screw holes 23 and the second positioning screw holes 33 are aligned with each other, and the mating ends of the first positioning screw holes 23 and the second positioning screw holes 33 are adapted to the positioning screws 4. After the first cladding component 2 and the second cladding component 3 are clamped, by using the thread adaptation of the positioning screws 4 and the first positioning screw holes 23 and the second positioning screw holes 33 on the two cladding components, the positioning screws 4 are screwed through and fixed in the first cladding component 2 and the second cladding component 3 to bolt-fasten the two cladding components, so that the cladding joint can be installed on the outside of the steel column body 1 without relying on external components.

[0027] A first flange 24 is provided at the bottom of the frame of the first fireproof board frame 21, and a first groove 25 having the same size as the first flange 24 is formed at the top of the frame of the first fireproof board frame 21. A second flange 34 is provided at the bottom of the frame of the second fireproof board frame 31, and a second groove 35 having the same size as the second flange 34 is formed at the top of the frame of the second fireproof board frame 31. After the installation of a single set of covering nodes is completed, the first grooves 25 and the first flanges 24 at the upper and lower ends of the first covering component 2, and the second grooves 35 and the second flanges 34 at the upper and lower ends of the second covering component 3 can be used for fitting and matching. The adjacent covering nodes up and down can be installed one by one in a sequential assembly manner, reducing the overall installation strength while improving the installation efficiency.

[0028] The working principle of the present utility model is as follows: When covering and protecting the steel column of building steel, based on the clamping of the first covering component 2 and the second covering component 3 with two U-shaped structures, in a way of mating and covering, it is clamped outside the steel column body 1 to form a square-structured covering protection frame. Then, after the first covering component 2 and the second covering component 3 are clamped, by using the threaded adaptation of the positioning screw 4 with the first positioning screw holes 23 and the second positioning screw holes 33 on the two covering components, the positioning screw 4 is screwed through and fixed in the first covering component 2 and the second covering component 3 to bolt-fasten the two covering components, so that the covering nodes can be installed outside the steel column body 1 without relying on external components. Further, after the installation of a single set of covering nodes is completed, the first grooves 25 and the first flanges 24 at the upper and lower ends of the first covering component 2, and the second grooves 35 and the second flanges 34 at the upper and lower ends of the second covering component 3 can be used for fitting and matching. The adjacent covering nodes up and down can be installed one by one in a sequential assembly manner until the overall structure of the steel column body 1 is covered. By using the covering sleeves of the first covering component 2 and the second covering component 3 in the form of fireproof board frames, the fire resistance, seismic resistance and durability of the steel column body 1 are improved. It is simple, convenient and efficient to operate, and is also convenient for subsequent disassembly, maintenance and recycling operations.
