Description

Technical Field

[0001] The utility model relates to a splicing tire frame with adjustable height, belonging to the technical field of high-rise building construction equipment. Background Art

[0002] With the rapid development of social economy, high-rise buildings are increasingly widely used. The structural conversion layer is a joint point where different structural forms in a building are connected. It is both the capping of the lower structure and the "air foundation" of the upper structure. It plays a vital role as a link in the entire building structure system. It is currently the most commonly used structural form for vertical conversion in high-rise buildings. The use of steel-concrete in the conversion layer can reduce the deadweight of the structure and improve its seismic performance. The structural design form of this type of building generally has the characteristics of large span, unique shape and complex structure. When the load of steel components needs to act on the formwork, it needs to be designed and calculated in advance. Taking the conversion layer of a high-rise building as an example, during the construction of the steel-concrete L-shaped cantilever composite structure, the steel column formwork is subjected to the concentrated load of the components, which cannot be borne by ordinary scaffolding. Additional tire frames are required as formwork support. During the construction of the cantilever composite component, due to the load, the formwork supported by the tire frame has settlement and deformation, and the traditional tire frame cannot adapt to the deformation of components and formwork under different loads. The existing tire frame has the disadvantages of inconvenient construction and poor adjustment ability. Utility Model Content

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] like Figures 1 to 5 As shown, a height-adjustable splicing tire frame includes a top unit 1, an adjustment unit 2, a tire frame unit 3 and a bottom unit 4 which are arranged in sequence from top to bottom. An adjustable base 5 is arranged at the bottom of the bottom unit 4. The adjustable base 5 includes a base steel plate 6, a cushion block 7 and a bolt assembly 8. The base steel plate 6 is welded to the bottom unit 4. The cushion block 7 is located between the base steel plates 6 and the base steel plates 6 are connected by the bolt assembly 8. The height-adjustable splicing tire frame includes at least one tire frame unit 3. The tire frame unit 3 is welded by steel, and the steel is cut into a suitable length. The tire frame unit 3 includes four vertical rods 10, twelve horizontal rods 9 and a plurality of oblique rods 11. The four vertical rods 10 are arranged parallel to each other in the vertical direction. The horizontal rods 9 are arranged on the sides of the square surrounded by the tops and bottoms of the four vertical rods 10. The oblique rods 11 are connected and arranged between adjacent vertical rods 10. Oblique rods 11 are arranged on each surface of the tire frame unit 3 to improve the overall structural strength of the tire frame and facilitate transportation and lifting.

[0017] The ends of the vertical rods 10 at the upper and lower ends of the tire frame unit 3 are provided with a plurality of connecting holes. The tire frame units 3 are stacked up and down in sequence. Adjacent tire frame units 3 are connected by passing bolt assemblies 8 through the connecting holes. The adjustable base 5 located at the bottom can adjust the height by adjusting the depth of the bolt assembly 8 and inserting the pad 7 for support.

[0018] The top unit 1 at the uppermost part includes main keels 12 located on all sides and secondary keels 13 cross-arranged inside the main keels 12 . The direction of the secondary keels 13 is perpendicular to the bottom support direction of the component, so that the load is evenly distributed on all keels.

[0019] According to the actual working conditions, the number of required tire frame units 3 is determined by calculating the size and length of the steel beam to be installed. According to the calculated steel beam erection position and height, the bottom unit 4 is first fixed, and a suitable pad 7 is selected to pad it. Then the bolt assembly 8 on the adjustable base 5 is rotated to adjust the base height, and the bottom unit 4 and the base steel plate 6 are welded to prevent lateral displacement. After that, the tire frame unit 3 is hoisted, and the upper and lower tire frame units 3 are fixed by passing the bolt assembly 8 through the connection hole. According to the height required by the engineering example, the appropriate number of tire frame units 3 are selected for connection.

[0020] The height-adjustable splicing tyre frame of the utility model adopts the idea of ​​dividing modules, stacking different numbers of tyre frame units 3, connecting the tyre frame height required for the actual construction situation through the bolt assembly 8, and adjusting the height through the adjustable base 5, so as to improve the adaptability in construction. In addition, the tyre frame as a whole has the advantages of convenient overlapping, fast construction speed, good adjustability, and is more convenient for the arching and settlement of the beam.

[0021] Finally, it should be noted that the above embodiments only illustrate the technical solutions of the present invention, rather than limiting it.
