Description

Technical Field

[0001] The utility model relates to the construction of reinforced concrete columns, in particular to a pouring and vibrating structure system of a combined steel formwork for super-high bent columns. Background Technique

[0002] When constructing reinforced concrete columns, the method of first erecting the formwork and then pouring the concrete is usually adopted. However, for columns with relatively high dimensions, if the method of erecting the formwork once and then pouring the concrete is adopted, it is difficult to vibrate the concrete under the column foot, the vibration is not dense, and phenomena such as honeycombing, pockmarks, and root rot are likely to occur, thus affecting the structural safety of the column; in addition, the formwork erection of the column is difficult and the accuracy is low, and bending deformation, formwork bulging, etc. are likely to occur during the pouring process, and it is difficult to ensure the forming quality of the column concrete pouring. Therefore, for cast-in-place concrete columns with relatively high dimensions, the method of erecting the formwork in sections and then pouring and vibrating is usually adopted. However, this method requires the lower column to reach the design strength before the upper column can be poured, the construction period is long, and there is a construction joint between the upper and lower columns, reducing the integrity of the structure. Content of the Utility Model

[0003] The purpose of the utility model is to propose a pouring and vibrating structure system of a combined steel formwork for super-high bent columns in view of the problems existing in the concrete pouring process of super-high bent columns, such as low operation efficiency, difficult formwork erection, low accuracy, and non-dense concrete vibration. In order to overcome the above difficulties, the utility model adopts the following technical solutions:

[0004] The utility model relates to a super-high rack column combined steel formwork casting and vibrating structure system, comprising an adjusting bracket, a supporting frame, and a standardized combined steel formwork, wherein the adjusting bracket is supported on the ground by anchor bolts, the supporting frame is supported on the adjusting bracket and sleeved on the outer side of the concrete column base, the standardized combined steel formwork is supported on the supporting frame, and the standardized combined steel formwork comprises a standard segment and a corbel segment, a self-closing vibration hole is provided on the side of the standard segment, and a self-closing side plate is provided at the vibration hole. The column concrete is cast by top pouring and multi-point vibration from bottom to top. After the concrete is poured from the top of the column, a vibrating rod is inserted through the vibration hole on the side of the standardized combined steel formwork to vibrate the concrete. After the vibration is completed, the vibrating rod is pulled out, and as the concrete pouring height rises, the poured concrete squeezes the self-closing side plate so as to Close the vibration hole, and then continue to vibrate the poured concrete through the vibration hole above; a corbel side formwork is provided on the side of the corbel segment to realize the integrated support of the corbel side formwork and the column formwork, reducing the difficulty of on-site support of the corbel side formwork; the supporting frame and the standardized combined steel formwork are in a "匚" shape, and the two supporting frames form a rectangular unit that is sleeved on the concrete column base. The two standardized combined steel formworks are spliced into a rectangular unit to form the formwork on the outside of the column, and the joints of adjacent supporting frames and standardized combined steel formworks are staggered. A downward "V"-shaped groove is provided on the top of the supporting frame and the standardized combined steel formwork, and a downward "V"-shaped protrusion is provided on the bottom of the standardized combined steel formwork. The "V"-shaped protrusion cooperates with the "V"-shaped groove to facilitate the positioning between segments when the standardized combined steel formwork is extended, thereby improving the efficiency of the extension operation.

[0005] Preferably, an adjusting nut is provided on the anchor bolt, and the elevation of the adjusting bracket is adjusted by the adjusting nut to adapt to the uneven ground and provide a flat foundation for the template support.

[0006] Preferably, support rods are provided on the sides of the support frame, and strip through holes are provided on the adjustment bracket and the support rods. Fixing bolts pass through the strip through holes of the support rods and the adjustment bracket to fix the support rods and the adjustment bracket to prevent the support frame from shifting, thereby providing stable and reliable support for the standardized combined steel mold.

[0007] Preferably, the upper edge portion of the shaped combined steel mold is provided with an upper docking wing plate, the lower edge portion is provided with a lower docking wing plate, and the side edge portion is provided with a side docking wing plate, which facilitates the splicing and extension operations of the shaped combined steel mold.

[0008] Preferably, a top sealing plate is provided on the top of the corbel side formwork. After the pouring and vibration of the corbel concrete is completed, the top sealing plate is used to seal the top of the corbel side formwork to prevent concrete from overflowing from the top of the corbel side formwork when continuing to pour the column concrete.

[0009] Preferably, the upper side of the self-closing side plate is hinged to the upper side of the vibrating hole. The self-closing side plate is flush with the surface of the standardized steel formwork to ensure the flatness of the column concrete. A limiting side ring is provided outside the vibrating hole, and the self-closing side plate is closely attached to the limiting side ring. By setting the limiting side ring, the further outward movement of the self-closing side plate is restricted. The principle of automatic closing of the vibrating hole is as follows: the self-closing side plate opens towards the inner side of the column. As the pouring height of the column concrete gradually rises, the concrete laterally squeezes the self-closing side plate, causing the self-closing side plate to closely adhere to the limiting ring, thereby closing the vibrating hole.

[0010] Preferably, sealing gaskets are provided at the upper docking wing plate, the lower docking wing plate, the side docking wing plate, and the limiting side ring to improve the sealing performance at the joint of the components.

[0013] 2. The side of the standard segment of the standardized combined steel formwork is provided with vibrating holes, which can be synchronously vibrated as the pouring height of the concrete rises, solving the problem of vibrating the lower-end concrete during the overall pouring of the ultra-high bent column; the vibrating holes adopt an automatic closing design, and a self-closing side plate that opens towards the inner side of the column is provided thereon, solving the problem of cumbersome on-site closing operation of the vibrating holes.

[0014] 3.

The elevation of the adjustment bracket 11 is adjusted through the adjustment nut 13 to adapt to the uneven ground condition and provide a flat foundation for formwork erection.

[0025] As shown in the attached Figure 2 figure, the support frame 14 is supported on the adjustment bracket 11 and sleeved outside the concrete column base 21. The standardized combined steel form is supported on the support frame 14. Support rod members 15 are provided on the side of the support frame 14. Strip through-holes 16 are provided on both the adjustment bracket 11 and the support rod members 15.
