Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a steel structure assembly mechanism for building construction. Background Art

[0002] Steel structure buildings are a building system different from traditional concrete buildings. Compared with concrete buildings, they use more prefabricated components, have higher construction efficiency, can be applied to a wider range of scenarios, and have equivalent or even stronger supporting strength, structural strength and seismic performance. Moreover, their steel structure prefabricated components can be reused, greatly reducing the generation of construction waste. Therefore, they are gradually widely adopted in the construction field.

[0003] The prefabricated components of existing steel structure buildings generally include channel steel (I-beam), rod-shaped components, columns, steel crossbeams and steel plates, etc. The assembly connections between different prefabricated components are generally carried out by riveting, bolt connection and welding. First, the columns are fixed, and then, with the columns as the support and foundation, a frame structure is built using channel steel, rod-shaped components, crossbeams, etc. Finally, the steel plates are assembled to form the top and walls to complete the overall frame construction of the building.

[0004] The above-mentioned steel structure buildings still have the following problems during the assembly and construction process: (1) Channel steel, rod-shaped components, columns and crossbeams are generally connected by riveting, bolt connection and welding. Among them, riveting and bolt connection bear a large local shear force and have limited longitudinal support performance, while welding is not easy to disassemble and is not conducive to recycling; (2) Columns are generally cylindrical, and their supporting surfaces for channel steel, rod-shaped components and crossbeams are small, resulting in an unsatisfactory structural performance of the assembled structure and being unable to effectively adjust the assembly height of channel steel, rod-shaped components and crossbeams.

Through the combination of the above features, the steel structure assembly mechanism for building construction can effectively solve the problem that the structural performance at the assembly positions of the channel steel, rod-shaped member, cross beam and column is not ideal during the assembly of the existing steel structure building.

Detailed implementation manners

[0030] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in combination with the embodiments and the drawings. The illustrative embodiments and descriptions thereof of the present utility model are only used to explain the present utility model and shall not be construed as a limitation to the present utility model.

[0031] Embodiment

[0032] Please refer to Figures 1 to 8 , this embodiment provides a steel structure assembly mechanism for building construction, including a lifting column 20, the lifting column 20 is vertically arranged, and the top end of the lifting column 20 is used to support the top surface structure of the building; Secondly, it includes a housing 30, the housing 30 is sleeved and fixedly connected to the lifting column 20, and several insertion channels 31 are horizontally penetrated through the housing 30; Thirdly, it includes at least a pair of closed clamping mechanisms, each of the closed clamping mechanisms corresponds to one of the insertion channels 31 respectively, the closed clamping mechanism is arranged in the housing 30, the closed clamping mechanism is provided with a clamping hole 40 and a horizontal push rod 41, the clamping hole 40 is penetrated through with the corresponding insertion channel 31 to penetrate a rod-shaped member to be assembled, the horizontal push rod 41 is horizontally slidably matched with the closed clamping mechanism, the horizontal push rod 41 can enlarge or reduce the clamping hole 40, several lifting pressure rods 32 are vertically slidably connected to the housing 30, the lifting pressure rods 32 correspond to the horizontal push rods 41 one by one, and are pivotally connected to the corresponding horizontal push rods 41 through a turning pressure rod 33, the turning pressure rod 33 is used to convert the downward pressure of the corresponding lifting pressure rod 32 into a horizontal pressure to push the corresponding horizontal push rod 41; Fourthly, it includes several open clamping mechanisms, the open clamping mechanisms are arranged above the housing 30, the bottom of the open clamping mechanisms is connected to all the lifting columns 32, and the open clamping mechanisms are used to horizontally clamp and fix the channel steel or cross beam to be assembled.

[0033] The steel structure assembly mechanism for building construction provided in this embodiment can adjust the height of the top surface structure of a building and indirectly adjust the assembly height of other prefabricated components by setting up the lifting column 20 and fixedly sleeving the housing 30 on the lifting column 20, taking advantage of the liftable property of the lifting column 20. The housing 30 can increase the contact area and structural performance at the assembly position of the lifting column 20. On this basis, a closed clamping mechanism is set up to clamp and fix rod-shaped components, and an open clamping mechanism is set up to support and fix channel steel or crossbeams. Specifically, by setting up the insertion channel 31 and the closed clamping mechanism, clamping holes 40 are opened in the closed clamping mechanism, and a horizontal push rod 41 is set. During use, the rod-shaped component is inserted into the insertion channel 31 and penetrates through the clamping holes 40, and then the horizontal push rod 41 is slid to narrow the clamping holes 40, thereby clamping the rod-shaped component. By setting up the open clamping mechanism above the housing 30, it horizontally clamps and fixes the channel steel or crossbeam to be assembled and provides support. On this basis, a lifting pressure rod 32 is set up vertically, with its top connected to the bottom of the open clamping mechanism, and a pivot pressure rod 33 is set up, with the pivot pressure rod 33 pivotally connected to the horizontal push rod 41. When the open clamping mechanism clamps and fixes the channel steel or crossbeam, it bears the weight of the channel steel or crossbeam and drives the lifting pressure rod 32 to press down, thereby driving the pivot pressure rod 33 to gradually turn horizontally, thus pushing the horizontal push rod 41 to slide, so as to narrow the clamping holes 40 and clamp the rod-shaped component using the gravity of the channel steel or crossbeam. Through the combination of the above features, the steel structure assembly mechanism for building construction can effectively solve the problem that the structural performance at the assembly positions of channel steel, rod-shaped components, crossbeams and columns is not ideal during the assembly of existing steel structure buildings.

[0034] To increase the support area of the housing 30 and ensure overall balance, the housing 30 is horizontally arranged in a cuboid shape and symmetrically distributed with the lifting column 20 as the center line.

[0035] To further ensure balance, the number of the insertion channels 31 is two. The two insertion channels 31 are arranged in parallel and symmetrically distributed on the housing 30 with the lifting column 20 as the center line.

[0036] To further ensure balance and the uniformity of clamping and fixing, the number of the closed clamping mechanisms is two pairs, and the two pairs of closed clamping mechanisms are symmetric with the lifting column 20 as the center line.

[0037] Preferably, the two closed clamping mechanisms in each pair of closed clamping mechanisms respectively correspond to one insertion channel 31.

[0038] In order to enable the lifting and pressing rod 32 to reset upward when not bearing a load (channel steel or cross beam), and to keep the clamping hole 40 at the maximum size for convenient insertion of the rod-shaped member, the bottom end of the lifting and pressing rod 32 is fixedly connected to the inner bottom surface of the housing 30 through a spring column 321. When the spring column 321 is in a natural state, the open clamping mechanism is at the highest working position. When the bottom of the clamping mechanism contacts the top of the housing 30, the turning and pressing rod 33 is in a horizontal state.

[0039] To further explain the specific structure of the closed clamping mechanism, the closed clamping mechanism includes a rectangular frame body 42. One side in the long side direction of the frame body 42 is slidably connected with a slider 421. The slider 421 is connected to the horizontal push rod 41, and the sliding direction is parallel to the sliding direction of the horizontal push rod 41. Inside the frame body 42, there are a first slider 43, a second slider 44, a third slider 45, a fixed block 46, a fourth slider 47 and a fifth slider 48. The first slider 43, the second slider 44, the third slider 45, the fixed block 46, the fourth slider 47 and the fifth slider 48 are respectively provided with clamping planes. The first slider 43, the second slider 44, the third slider 45, the fixed block 46, the fourth slider 47 and the fifth slider 48 are sequentially slidably arranged, and the sliding directions are respectively parallel to the six clamping planes, so that the six clamping planes enclose and form the clamping hole 40 with a variable area in the shape of a regular hexagon. At least one pair of guide plates 49 are provided on at least one side in the thickness direction of the frame body 42. One guide plate 49 is connected to the slider 421, and the other is connected to the frame body 42, so that the two guide plates 49 can approach or move away from each other. The guide plate 49 is provided with two guide chutes 491. The second slider 44 and the third slider 45 are respectively slidably connected to one guide plate 49 through the two guide chutes 491. The fourth slider 47 and the fifth slider 48 are respectively slidably connected to the other guide plate 49 through the two guide chutes 491. When the two guide plates 49 approach or move away from each other, the size of the clamping hole 40 decreases or increases.

[0040] To further explain the shapes and movement paths of the first slider 43, the second slider 44, the third slider 45, the fixed block 46, the fourth slider 47, and the fifth slider 48, the first slider 43 is fixedly connected to the slider 421, and the included angle between the clamping plane of the first slider 43 and the sliding direction of the slider 421 is 120°; the included angle between the clamping plane of the second slider 44 and the sliding direction of the slider 421 is 60°, and the second slider 44 is slidably engaged with the first slider 43 along its own clamping plane; the clamping plane of the third slider 45 is parallel to the sliding direction of the slider 421, and the third slider 45 is slidably engaged with the second slider 44 along its own clamping plane; the fixed block 46 is fixedly connected to the frame 42, and the clamping plane of the fixed block 46 is arranged parallel to the clamping plane of the first slider 43, and the third slider 45 is slidably engaged with the fixed block 46 along the clamping plane of the fixed block 46; the clamping plane of the fourth slider 47 is arranged parallel to the clamping plane of the second slider 44, and the fourth slider 47 is slidably engaged with the fixed block 46 along its own clamping plane; the clamping plane of the fifth slider 48 is arranged parallel to the clamping plane of the third slider 45, and the fifth slider 48 is slidably engaged with the fourth slider 47 along its own clamping plane, and the fifth slider 48 is slidably engaged with the first slider 43 along the clamping plane of the first slider 43.

[0041] By setting the above structure, during the process of changing the size of the clamping hole 40 of the closed clamping mechanism, the center always remains on the same horizontal plane, thereby effectively regulating the assembly height of the rod-shaped member.

[0042] It should be noted that the regular hexagon-shaped clamping hole 40 can accommodate rod-shaped members of most shapes, such as cylindrical, prismatic, and rod-shaped members with ribs, etc.

[0043] To further explain the specific structure of the open clamping mechanism, the open clamping mechanism includes a plurality of bearing seats 60. The bottom of the bearing seat 60 is connected to a plurality of lifting and pressing rods 32. A slot 61 is formed through the top of the bearing seat 60 along the length direction. The slot 61 is used to carry the channel steel or cross beam to be assembled horizontally. The depth of the slot 61 is greater than the edge thickness of the channel steel to be assembled; the slot wall of the slot 61 is connected to a clamping plate 63 through a cylinder 62. The clamping plate 63 is used to contact and press against the bottom surface of the channel steel to be assembled, or to contact and press against the side wall of the cross beam to be assembled.

[0044] Through the above settings, the groove 61 is used to accommodate the horizontally arranged channel steel or cross beam to be assembled, and preliminary swing limit is carried out. By setting the cylinder 62 and the clamping plate 63, the side wall of the cross beam is clamped, and while clamping the channel steel, clamping connection is implemented.

[0045] In order to avoid hard contact between the bearing seat 60 and the housing 30, an elastic buffer layer 64 is laid on the bottom surface of the bearing seat 60.

[0046] The specific embodiments described above further elaborate on the purpose, technical solution and beneficial effects of the present invention. It should be understood that the above description is only the specific embodiments of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
