Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring support, and particularly relates to a deformation-preventing support structure for concrete pouring of shear wall columns in high-rise buildings. Background Art

[0002] In the field of high-rise building construction, shear wall columns, as important vertical load-bearing and lateral force-resistant members, the quality of their concrete pouring is directly related to the safety and stability of the building structure. In the traditional construction process of concrete pouring for shear wall columns in high-rise buildings, since the concrete will generate a large lateral pressure on the formwork and support structure during pouring, especially in high-rise buildings, as the pouring height increases, this lateral pressure will become more significant. The existing support structures often have difficulty effectively coping with this complex stress situation, and problems such as unstable support and deformation are likely to occur. Once the support structure deforms, it will lead to dimensional deviation and surface unevenness of the shear wall column, and even affect its overall mechanical properties, thus posing a potential threat to the safety of the entire building structure. Therefore, it is of great practical significance to develop a support structure for concrete pouring of shear wall columns in high-rise buildings that can effectively prevent deformation.

The disclosed contents of various publications, patents, and published patent specifications cited herein are incorporated herein by reference in their entirety. The technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model.

[0025] Embodiment 1: During the concrete pouring process of shear wall columns on the standard floor of a high-rise building, first, the binding work of the steel reinforcement cage 1 is carried out to make the size and shape of the steel reinforcement cage 1 meet the design requirements. Subsequently, the support frame mechanism 2 is installed. Four steel plates 21 are enclosed to form a rectangle, and the steel plates 21 are connected and fixed through the threaded holes 26 opened on their side walls and the matching bolts. On the outer end surface of each steel plate 21, 2 horizontally arranged cross beams 23 and 2 vertically arranged longitudinal beams 22 are fixed. The cross beams 23 and the longitudinal beams 22 are welded and fixed to the steel plate 21 to enhance the overall strength of the support frame mechanism 2. A number of pin holes 24 are linearly arranged at equal distances on the bottom surface of the steel plate 21, and a number of pin rods 25 are linearly arranged and fixed at equal distances on the top surface. The size of the pin rods 25 is adapted to the size of the pin holes 24, so that in the subsequent construction process, if it is necessary to increase the support height, the pin rods 25 at the bottom of another steel plate 21 can be coupled and inserted into the pin holes 24 at the top of the lower steel plate 21 to realize the sequential upward stacking of the steel plates 21.

[0026] Then, the anti-deformation bracket 3 is installed. Four rectangular plates 31 are respectively fixed on the outer surface of the steel plate 21. The inner surface of the rectangular plate 31 is welded and fixed to the longitudinal beam 22 and the cross beam 23 on the outside of the steel plate 21. On the outside of each rectangular plate 31, 2 internal threaded pipes 34 are respectively arranged. Both ends of the internal threaded pipe 34 are screwed and connected with a threaded rod 33. The end of the threaded rod 33 is hinged to the connecting seat 32 through a shaft pin. Among them, the inner connecting seats 32 are respectively welded and fixed to the outer side wall of the rectangular plate 31, and the end of the outer connecting seat 32 far from the threaded rod 33 is welded and fixed to the side wall of the protruding end of the steel plate 21. At this time, a triangular structure is formed among the rectangular plate 31, the threaded rod 33, the internal threaded pipe 34 and the protruding section of the steel plate 21. This triangular structure can effectively support the steel plate 21 at the current position and prevent the steel plate 21 from protruding and deforming outward due to the concrete pouring pressure during the concrete pouring process. During the concrete pouring process, by rotating the internal threaded pipe 34, since two sections of threads adapted to the outer thread of the threaded rod 33 are arranged on the side wall of the inner cavity of the internal threaded pipe 34 and these two sections of threads are symmetrical to each other, rotating the internal threaded pipe 34 can drive the threaded rods 33 to approach or move away from each other, thereby adjusting the support force of the anti-deformation bracket 3 to adapt to different pouring situations.

[0027] Example 2: When pouring the concrete of the shear wall column at the corner of a high-rise building, the binding of the steel reinforcement cage 1 needs to be adjusted according to the special shape at the corner so that the steel reinforcement cage 1 can closely fit the corner structure. When installing the support frame mechanism 2, 4 steel plates 21 are also enclosed to form a rectangle. However, since it is at the corner, two of the steel plates 21 need to be specially processed according to the corner angle so that they can better fit the corner. The connection between the steel plates 21 is still fixed by the threaded holes 26 and bolts, making the connection firm. The installation methods of the cross beam 23 and the longitudinal beam 22 are the same as those of the standard floor and are welded to the steel plates 21 to enhance the stability of the support frame mechanism 2.

[0028] During the installation of the anti-deformation bracket 3, due to the space limitation at the corner, when installing the rectangular plate 31, the installation position of the rectangular plate 31 needs to be adjusted according to the actual situation so that it can be effectively connected to the longitudinal beam 22 and the cross beam 23 outside the steel plate 21, and generally it is fixed by welding. When connecting the threaded rod 33 and the internal threaded tube 34, it is necessary to pay attention to rotating the internal threaded tube 34 to adjust the position of the threaded rod 33 so that the outer connecting seat 32 can be smoothly welded to the protruding side wall of one end of the steel plate 21. Since the concrete pouring pressure distribution at the corner may be uneven, before the concrete pouring, it is necessary to adjust the supporting force of the anti-deformation brackets 3 at different positions separately by rotating the internal threaded tube 34 according to the design requirements and the actual situation on site, so that the steel plate 21 at the corner will not be deformed due to uneven force during the concrete pouring process. During the concrete pouring process, continuously observe the states of the support frame mechanism 2 and the anti-deformation bracket 3. If it is found that the supporting force at a certain place is insufficient, the corresponding internal threaded tube 34 can be rotated in time for adjustment.

[0029] Example 3: For special-shaped shear wall columns in high-rise buildings, such as shear wall columns with arc or irregular shapes, when binding the steel reinforcement cage 1, it is necessary to strictly follow the design drawings so that the arrangement of the steel bars can adapt to the special-shaped structure. The installation of the support frame mechanism 2 needs to be customized according to the shape of the special-shaped shear wall column. The shape and size of the steel plates 21 need to be cut and processed according to the special-shaped structure so that they can closely fit the periphery of the shear wall column. The connection between the steel plates 21 still adopts the method of threaded holes 26 and bolts. However, during the connection process, special jigs or tools need to be used to assist in positioning to ensure the connection accuracy. The installation of the cross beam 23 and the longitudinal beam 22 also needs to be adjusted according to the special-shaped structure. It may be necessary to bend or specially process some parts to adapt to the shape of the steel plates 21 and be welded to the steel plates 21.

[0030] The installation of the anti-deformation bracket 3 needs to be arranged according to the force characteristics of the special-shaped structure. When installing the rectangular plate 31, its position needs to be accurately measured so that it can be effectively connected to the cross beam 23 and the longitudinal beam 22 on the outside of the steel plate 21, and generally it is fixed by welding. When connecting the threaded rod 33 and the internal threaded pipe 34, due to the complexity of the special-shaped structure, the initial lengths and angles of the threaded rod 33 and the internal threaded pipe 34 of the anti-deformation brackets 3 at different positions may be different, and they need to be adjusted according to the actual situation. The connection of the outer connecting seat 32 to the side wall of the protruding end of the steel plate 21 also needs special treatment according to the special-shaped structure, and local strengthening may be required at the connection part to make the connection firm. Before the concrete pouring, the force condition of the special-shaped shear wall column needs to be simulated by means of finite element analysis and other methods. According to the simulation results, the support force of each anti-deformation bracket 3 is accurately adjusted, and the threaded rod 33 is made to reach the appropriate length by rotating the internal threaded pipe 34, so as to form a stable triangular support structure. During the concrete pouring process, closely monitor the deformation of the support frame mechanism 2 and the anti-deformation bracket 3. If any abnormality is found, take measures in time to adjust, such as rotating the internal threaded pipe 34 again to change the support force, so that the special-shaped shear wall column does not deform during the concrete pouring process.

[0031] According to the above-mentioned preferred technical solution, the working process of this technical solution is described as follows: Carry out the binding work of the steel reinforcement cage 1. The construction personnel bind the steel bars according to the specified spacing and shape according to the requirements of the design drawings, so that the size and shape of the steel reinforcement cage 1 meet the design specifications, providing a stable steel bar framework for the subsequent concrete pouring. After the binding of the steel reinforcement cage 1 is completed, start to install the support frame mechanism 2. The construction personnel carry 4 steel plates 21 to the designated positions to form a rectangular structure. On the side walls of the steel plates 21 close to each other, using the pre-opened threaded holes 26, the steel plates 21 are connected and fixed to each other by the matching bolts to ensure the stability of the overall structure of the support frame mechanism 2.

[0032] During the installation of the steel plate 21, the 2-3 horizontally arranged cross beams 23 and 2-3 vertically arranged longitudinal beams 22 fixed on the outer end faces of each steel plate 21 are also installed in place. The cross beams 23 and the longitudinal beams 22 are fixed to the steel plate 21 by welding, further enhancing the strength and stiffness of the support frame mechanism 2 to withstand the pressure generated during the subsequent concrete pouring process. When it is necessary to increase the support height, the construction workers hoist another steel plate 21 above the already installed steel plate 21, and couple and insert the pin rod 25 at the bottom of this steel plate 21 into the pin hole 24 at the top of the lower steel plate 21 to achieve the sequential upward stacking of the steel plates 21. The cooperation between the pin rod 25 and the pin hole 24 provides positioning and preliminary fixing for the stacking of the steel plates 21. After the installation of the support frame mechanism 2 is completed, the anti-deformation bracket 3 is installed. The construction workers carry 4 rectangular plates 31 to the outer surfaces of the steel plates 21 respectively, and fixedly connect the inner surfaces of the rectangular plates 31 to the longitudinal beams 22 and the cross beams 23 on the outside of the steel plates 21 by welding, making the rectangular plates 31 firmly installed. On the outside of each rectangular plate 31, the construction workers install 2 internal threaded pipes 34, screw the two threaded rods 33 to the two ends of the internal threaded pipes 34 respectively, and the ends of the threaded rods 33 are hinged to the connecting seats 32 through shaft pins. Among them, the inner connecting seat 32 is fixedly welded to the outer side wall of the rectangular plate 31, and one end of the outer connecting seat 32 away from the threaded rod 33 is fixedly welded to the side wall of the protruding end of the steel plate 21. At this time, a triangular structure is formed among the rectangular plate 31, the threaded rod 33, the internal threaded pipe 34 and the protruding section of the steel plate 21, and this structure can effectively support the steel plate 21 at the current position.

[0033] Before the concrete pouring, the construction workers adjust the supporting force of the anti-deformation bracket 3 by rotating the internal threaded pipe 34 according to the design requirements and the actual situation on site. Since there are two sections of threads on the inner cavity side wall of the internal threaded pipe 34 that are adapted to the outer ring threads of the threaded rod 33, and these two sections of threads are symmetric to each other, rotating the internal threaded pipe 34 can drive the threaded rods 33 to approach or move away from each other, thereby changing the overall length of the anti-deformation bracket 3, and further adjusting the supporting force to adapt to different pouring situations. After completing the above preparatory work, the concrete pouring begins. During the pouring process, the concrete will exert pressure on the support frame mechanism 2. At this time, the triangular structure formed by the anti-deformation bracket 3 plays a role, and the support steel plate 21 prevents it from bulging and deforming outward due to the concrete pouring pressure. The construction workers continuously observe the states of the support frame mechanism 2 and the anti-deformation bracket 3. If it is found that the supporting force at a certain place is insufficient, the corresponding internal threaded pipe 34 can be rotated in time to drive the threaded rod 33 to move, changing the supporting force of the anti-deformation bracket 3, so that the support structure remains stable throughout the concrete pouring process, ensuring the pouring quality of the shear wall column. When the concrete pouring is completed and the concrete reaches a certain strength, the construction workers first remove the anti-deformation bracket 3, separate the internal threaded pipe 34 from the threaded rod 33, and remove components such as the rectangular plate 31. Then, the support frame mechanism 2 is removed. By loosening the bolts in the threaded holes 26, the steel plates 21 are removed one by one. Finally, the removed components are cleaned and maintained for future use.

[0034] Only some exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
