Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically to a inclined column formwork support system. Background Technology

[0002] With the advancement of structural design theory and the innovation of architectural design concepts, a large number of complex and irregularly shaped buildings have emerged, and the construction of these structures places increasingly higher demands on the formwork and scaffolding support system.

[0003] For example, giant concrete inclined columns in super high-rise buildings often form an outer frame tube together with giant beams, transfer trusses, and secondary frames, sharing lateral loads with the core tube. In some structural systems, giant concrete inclined columns are connected to ordinary edge columns to increase the lateral stiffness of the outer frame, so that the seismic shear force borne by the outer frame reaches a certain proportion of the total shear force at the base.

[0004] Due to the tilting of the column during construction, the reinforcement of the formwork is difficult. Currently, the formwork for giant inclined columns is usually supported by two rows of external support frames erected on the outside of the giant column using steel pipes. This method requires a large amount of steel pipes to form a support system and has a long construction period. Alternatively, a steel structure frame support system can be used, but the design of the steel structure frame is specific and difficult to reuse. It also takes a long time to install and dismantle, affecting the construction period, and the quality of on-site welding is difficult to guarantee.

[0005] Therefore, how to provide a giant inclined column formwork support system that can be reused and effectively reduce the construction cycle is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides a support system for inclined column formwork, which uses existing materials to support giant inclined column formwork, making it easy to assemble and efficient in construction.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A inclined column formwork support system, supported on a floor slab, includes a standard section of a construction elevator, a steel frame, distribution beams, and formwork;

[0009] Multiple standard sections of the construction elevator are bolted together end to end to form multiple support frames of different heights. The multiple support frames are arranged in a stepped manner along the axis of the giant inclined column. There are multiple steel frames, which are fixed one-to-one at the top of the multiple support frames of different heights. One side of the multiple steel frames is an inclined plane with the same inclination direction as the giant inclined column. One side wall of the distribution beam is fixed to the inclined plane of the multiple steel frames. The template is fixed to the other side of the distribution beam.

[0010] The beneficial effects of the above technical solution are that by using the standard section of the construction elevator as the support for the inclined column formwork, the support for the inclined column formwork can be completed simply by processing the steel frame according to the inclination of the inclined column. The amount of welding work is small, and it is easy to relocate and reuse.

[0011] Preferably, the floor slab has embedded steel plates on the top surface corresponding to the construction elevator standard section and the distribution beam, and the bottom ends of the bottom construction elevator standard section and the distribution beam are bolted to the embedded steel plates by anchor bolts. Anchoring the bottom ends of the bottom construction elevator standard section and the distribution beam to the floor slab via embedded steel plates improves the stability and effectiveness of the formwork support.

[0012] Preferably, the steel frame includes horizontal bars, vertical bars, and diagonal bars. One end of each vertical bar is vertically fixed to one end of the horizontal bar. Both ends of each diagonal bar are fixed to the other ends of the horizontal bar and the vertical bar, respectively, to form a triangular support frame. Multiple triangular support frames are provided, and adjacent triangular support frames are connected by connecting rods. The steel frame is individually welded into a right-angled triangle shape adapted to the slope of the inclined column, facilitating formwork reinforcement. When constructing inclined columns with different slopes, only the steel frame needs to be relocated. The elevator construction standard sections are reusable, making construction more convenient and efficient.

[0013] Preferably, the system further includes a support rod, which is placed inside the triangular support frame. One end of the support rod is fixed to the outer wall of the diagonal brace, and the other end is fixed to the connection node between the horizontal bar and the vertical bar. The support rod improves the overall stability of the steel frame, giving it sufficient load-bearing capacity.

[0014] Preferably, the distribution beam is an I-beam.

[0015] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a support system for inclined column formwork, which uses the standard section of construction elevator as the support for inclined column formwork. Different forms of steel frames can meet the construction of inclined columns with different inclinations. The standard section of construction elevator can be reused. The support system has a small amount of welding work, is easy to assemble, and the reusable method can greatly reduce material waste, making construction more efficient and convenient.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model embodiment discloses an inclined column formwork support system, which is supported on the floor slab 7, including a standard section of construction elevator 1, a steel frame 2, a distribution beam 3 and a formwork 4;

[0026] like Figure 1 As shown, the standard sections of the construction elevator are sequentially spliced ​​to different heights to form a support frame. The steel frame is welded and fixed to the top of the support frame, forming a stepped support. The template and the steel frame can be fixed by welding or bolting. The construction elevator standard sections are easy to assemble, only requiring the steel frame to be processed according to the slope of the inclined column. The elevator standard sections can be lifted by bolting, with minimal welding work. The elevator standard sections can be reused, greatly reducing material waste.

[0027] In this embodiment, at least two rows of support frames of the same height are provided, and each support frame is provided with a steel frame; alternatively, a steel frame may be provided on support frames of the same height in the same row, with the length of the steel frame being greater than the cross-sectional width of the inclined column.

[0029] like Figure 2 As shown, by setting pre-embedded steel plates on the top surface of the floor slab, it is ensured that the standard section of the construction elevator and the distribution beam can be anchored to the floor slab as a whole, preventing the slippage or tilting of the support system during construction, and ensuring safe and effective construction.

[0030] To further optimize the above technical solution, the steel frame 2 includes a horizontal bar 21, an upright bar 22 and a diagonal bar 23. One end of the upright bar 22 is vertically fixed to one end of the horizontal bar 21, and the two ends of the diagonal bar 23 are respectively fixed to the other ends of the horizontal bar 21 and the upright bar 22 to form a triangular support frame. There are multiple triangular support frames, and adjacent triangular support frames are connected by a connecting rod 25.

[0031] like Figure 3 As shown, the steel frame is a right-angled triangle, with its hypotenuse having the same inclination angle as the inclined column. The support capacity of the steel frame is improved by the inclined rod.

[0032] To further optimize the above technical solution, a support rod 24 is also included. The support rod 24 is placed in the inner cavity of the triangular support frame, with one end fixed to the outer wall of the diagonal rod 23 and the other end fixed at the connection node between the horizontal rod 21 and the vertical rod 22.

[0033] like Figure 4 As shown, at least two triangular steel frames are provided, and the two triangular steel frames are connected by support rods to ensure the overall stability of the entire steel frame and to have sufficient rigidity to withstand the loads of the formwork and concrete.
