Description

Technical Field

[0001] This application belongs to the technical field of building construction, and particularly relates to a reinforcement structure for large-section steel-concrete columns. Background Art

[0002] Steel reinforced concrete columns, abbreviated as steel-concrete columns, refer to reinforced concrete structures in high-rise buildings where steel sections are placed in columns to enhance the bearing capacity of the columns in order to compress the cross-section of concrete columns. During the construction of steel-concrete columns, the gap between the upper and lower formworks is prone to leaking mortar, and sealing strips are often used for blocking. However, the sealing strips do not have a reinforcement effect. During the subsequent pouring and curing process, due to reasons such as formwork bulging and deformation, the ends of the formworks are prone to bending and deformation, not only resulting in the problem of enlarged gaps and mortar leakage, but also affecting the final forming effect of the column body. Summary of the Utility Model

[0003] The purpose of this application is to provide a reinforcement structure for large-section steel-concrete columns, which solves the problems of sealing and reinforcement of the gaps between the upper and lower formworks of existing steel-concrete columns.

The baffle blocks the gap between the upper and lower formworks. The bases are connected to a tying component. The tying component passes through the baffle and the gap between the upper and lower formworks to be connected to the steel section. Adjacent bases are connected by a connecting component.

[0006] Further, the formworks enclose a rectangular column body pouring space.

[0030] The following further describes this application in conjunction with specific embodiments and the accompanying drawings.

[0031] Refer to Figures 1 to 5 As shown, a reinforcement structure for a large-section steel-concrete column includes a base 1, a baffle 2, a tie rod 3, a clip 4, a connecting rod 5, section steel 6, a formwork 7, a crossbeam 8, a snap ring 9, a fastening ring 10, and a fastening end 11.

[0032] The reinforcement structure of this embodiment is constructed for a rectangular steel-concrete column, and the formworks 7 on all four sides enclose a rectangular column pouring space. Section steel 6 is arranged inside the formwork 7. The middle part of the section steel 6 is in a cross shape, and the four ends of the cross shape are welded with relatively perpendicular wing plates. The section steel 6, steel bars, and concrete together form a steel-concrete column.

[0033] A number of bases 1 are arranged. For adjustment according to different shapes of steel-concrete columns, the bases 1 in this embodiment are also arranged on all four sides. A number of bases 1 surround the outside of the formwork 7. A baffle 2 is supported inside the base 1, and the baffle 2 is blocked at the gap between the upper and lower formworks 7 to seal the gap and prevent leakage of slurry.

[0034] The base 1 adopts a rectangular frame structure. The middle part of the base 1 is connected to a tie assembly. The tie assembly passes through the baffle 2 and the gap between the upper and lower formworks 7 to be connected to the section steel 6. That is, the section steel 6 serves as an internal anchor point to act on the tie assembly, and the tie assembly acts on the base 1. Finally, the supporting effect of the section steel 6 acts on the baffle 2 to ensure the stability of the formwork structure at this place and prevent deformation.

[0035] The tie assembly includes a tie rod 3 and a clip 4. The tie rod 3 is connected to the base 1. The tie rod 3 passes through the baffle 2 and the gap between the upper and lower formworks 7. The tie rod 3 is connected to the clip 4, and the clip 4 is clamped on the section steel 6. A hole for the tie rod 3 to pass through is provided in the middle of the baffle 2. A complete round hole is formed relatively between the upper and lower formworks 7 (with semi-circular grooves at the ends) for the tie rod 3 to pass through.

[0036] The wedge 4 is of a C-shaped structure, so that the wedge 4 can be clamped on the wing plate outside the profiled steel 6 to provide an anchor point for the pulling and connecting function. The wedge 4 is adjustably connected to the pull rod 3 in the inner and outer directions, so that the clamping position of the wedge 4 relative to the pull rod 3 can be adjusted to meet different clamping lengths.

[0037] Specifically, the wedge 4 is inserted through the pull rod 3, and a nut for clamping the wedge 4 is screwed on the pull rod 3, and the locking and limiting of the wedge 4 relative to the pull rod 3 are realized by using the nut. Similarly, the nut can also be directly used as a part of the wedge 4, and the position of the wedge 4 is adjusted by rotating the wedge 4.

[0038] The pull rod 3 is adjustably connected to the base 1 in the inner and outer directions, so that the position of the base 1 relative to the pull rod 3 can be adjusted to meet different pulling and connecting lengths of the pull rod 3. Specifically, the pull rod 3 is inserted through the base 1, and a nut for clamping the base 1 is screwed on the pull rod 3, and the locking and limiting of the base 1 relative to the pull rod 3 are realized by using the nut. Similarly, the nut can also be used as a part of the base 1.

[0039] Adjacent two bases 1 are connected by a connecting component, and the connecting component acts on the end of the base 1, so that the base 1 and the connecting component jointly form a complete ring structure acting on the formwork 7. The connecting component includes a bent or curved connecting rod 5, and the two ends of the connecting rod 5 are respectively connected to a base 1, so that the connecting rod 5 realizes the angular transition and turning to ensure that all the bases 1 can be connected into a closed whole.

[0040] In this embodiment, the connecting rod 5 is of an L-shaped structure to realize the right-angle transition between two adjacent bases 1. The connecting rod 5 is adjustably connected to the base 1 in the vertical direction (side length direction) of the inner and outer directions, so that the contour formed by the base 1 and the connecting rod 5 can be expanded or contracted to meet the column cross-sections of different specifications and sizes. The end of the connecting rod 5 is inserted through the base 1, and a nut for clamping the base 1 is screwed on the connecting rod 5 for adjustment or locking.

[0041] A plurality of cross beams 8 are arranged, and are adjusted according to different-shaped steel-concrete columns. In this embodiment, the cross beams 8 are also arranged on all four sides. A plurality of cross beams 8 surround the outside of the formwork 7, and all the cross beams 8 form a complete ring structure acting on the formwork 7. The cross beam 8 is provided with a clamping ring 9 and a fastening ring 10 that are adjustable along the beam length direction. Specifically, the clamping ring 9 and the fastening ring 10 are screwed on the cross beam 8, and the position can be adjusted by self-rotation.

[0042] The clamping ring 9 clamps the adjacent cross beam 8 inward to provide an inward supporting force for the cross beam 8 to ensure that the cross beam is in close contact with the column (wood square). Specifically, the clamping ring 9 includes a ring sleeve and a clamping head. The ring sleeve is sleeved and connected to the cross beam 8, and the clamping head stands on the outside of the ring sleeve and the clamping head clamps the adjacent cross beam 8. Since the ring sleeve is locked by threads, the clamping head presses the cross beam 8 inward.

[0043] The quantity and position of the fastening ring 10 can be adjusted flexibly. The fastening ring 10 is provided with a fastening end 11 that inwardly props against the template 7. The fastening end 11 acts on the template 7 inwardly to achieve the support of the template 7 and ensure the strength of its supporting enclosure. The fastening end 11 is a structure with adjustable propping length, such as a telescopic sleeve, and thus it can be adjusted by itself to meet different propping distances.

[0044] The basic example of the present application and its various further alternative examples described above can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in the present application. In the solution of the present application, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0045] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
