Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a tall formwork support frame with enhanced lateral stability. Background Art

[0002] Tall formwork is mainly used for concrete pouring. It has the characteristics of large spatial span and heavy weight. It is suitable for large public facilities, large temples, buildings and other construction projects. It has the characteristics of strong stability and high bearing capacity. In order to improve the quality and safety performance of the building, relevant supporting structures are usually used to reinforce the tall formwork. You can refer to the relevant patent No. CN221567815U. Its essence is to fix the mounting screw through the mounting base, and use the rotating mounting rod to insert the connecting rod on the mounting rod into the connecting groove of the adjacent mounting rod, and realize the splicing of multiple connecting components, and complete the fixed connection between the fixing rod, connecting rod and mounting rod through the elastic part, so as to achieve the effect of convenient installation of the support frame.

[0003] Let's take the reinforcement method of tall rectangular column formwork as an example: traditional steel pipe fastener reinforcement requires splicing steel pipes of different lengths according to the column size, which is time-consuming and requires a large number of accessories. In addition, the lateral pressure during the pouring of concrete for tall columns is extremely high. Traditional steel pipe reinforcement requires additional auxiliary structures such as diagonal braces and sweeping rods, which take up a large space. Therefore, while fully realizing the use of modular design to meet the rapid reinforcement of tall formwork of different sizes, it is also necessary to consider the perspective of enhancing the lateral support force of the formwork and further enhancing its anti-overturning ability. To this end, we provide tall formwork support frames with enhanced lateral stability to solve the above problems. Utility Model Content

[0004] The purpose of the present invention is to provide a tall formwork support frame with enhanced lateral stability, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A tall formwork support frame with enhanced lateral stability is used to support tall formwork on rectangular columns.

Side support units are also provided on the sides of the modular fixing units to limit the modular fixing units and further enhance the lateral stability of the tall formwork.

[0007] The modular fixing unit includes a shell movably mounted on the side of the tall template, a limit block slidably mounted inside the side of the shell for supporting, and a threaded rod movably mounted inside the side of the limit block for connecting;

After the connecting rod and the threaded rod are coaxially assembled, the limit block is installed on the outside of the threaded rod according to the preset phase difference. After the adjacent support components are riveted with the clamping block, secondary tightening is implemented by the limit bolt to enhance the lateral shear performance. The threaded rod is tightened and the pre-tightening force is applied by the bolts on its surface to form a multi-level reinforcement system. The overall rigidity of the tall formwork is enhanced by coordinating the support units with equal distances.

However, it should be noted that many of the details listed in this specification are merely provided to help the reader gain a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0024] See also Figures 1 to 5 The utility model provides a tall formwork support frame with enhanced lateral stability. The technical solution is as follows:

[0025] Example 1: Figure 1-5As shown, the utility model provides a tall formwork support frame with enhanced lateral stability, which is applied to the support operation of the tall formwork 1 of the rectangular column. The side of the tall formwork 1 is provided with a modular fixing unit 2 whose size can be adjusted according to actual use requirements, so as to support the tall formwork 1 of different sizes. The side of the modular fixing unit 2 is provided with a side support unit 3 for limiting the modular fixing unit 2 and further enhancing the lateral stability of the tall formwork 1. The modular fixing unit 2 includes a shell 21 movably mounted on the side of the tall formwork 1, a limit block 25 slidably mounted on the inside of the side of the shell 21 for supporting, and a threaded rod 22 movably mounted on the inside of the side of the limit block 25 for connecting. The side of the threaded rod 22 is threadedly connected with a connecting rod 23. There are two shells 21 and they are slidably connected to the left and right sides of the limit block 25. The top surface of the shell 21 is internally threaded with a limit bolt 24.

[0026] The combined support unit is composed of two shells 21 and a limit block 25. Radial limit structures are provided on both sides of the limit block 25 to realize the anti-fall constraint and sliding guide function of the shell 21. The connecting rod 23 is set at the axial position of the tall template 1. The four-way distributed threaded rod 22 forms a tension transmission system to ensure the rigid fixation of the limit block 25, thereby providing a stable lateral constraint force to ensure the structural stability of the tall template 1.

[0027] The side of the limit block 25 is fixedly connected to the limit frame 26, the push rod 31 is movably connected to the inside of the limit frame 26, the top surface of the limit block 25 is fixedly connected to the fastening threaded rod 27, the top surface of the housing 21 is fixedly connected to the connecting block 28, the fastening threaded rod 27 is slidably connected to the inside of the connecting block 28, the side of the housing 21 is fixedly connected to the clamping block 29, and the limit bolt 24 is threadedly connected to the top surface of the clamping block 29;

[0028] The supporting components composed of the shell 21 and the limit block 25 are distributed on the four sides of the tall template 1 in an orthogonal symmetrical layout. The adjacent components adopt a reverse installation design, are riveted through the clamping block 29, and cooperate with the limit bolt 24 to form a rigid node. The top and bottom of the limit block 25 are provided with a two-way adjustment mechanism, and the sliding limit of the shell 21 is realized by the cooperation of the fastening threaded rod 27 and the connecting block 28, so that the device can adapt to the fixing requirements of rectangular columns with different cross-sectional sizes.

[0029] In this embodiment, after the connecting rod 23 and the threaded rod 22 are coaxially assembled, the limit block 25 is installed on the outside of the threaded rod 22 according to a preset phase difference. After the adjacent support components are riveted by the clamping block 29, secondary tightening is implemented by the limit bolt 24 to enhance the lateral shear resistance. The threaded rod 27 is tightened and a pre-tightening force is applied by the bolts on its surface to form a multi-stage reinforcement system, and the overall rigidity of the tall formwork 1 is enhanced by coordinating the equidistantly distributed support units.

[0030] Example 2: Figure 1-5 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the side support unit 3 includes a push rod 31 movably mounted on the side of the limit block 25, and a reinforcing plate 32 fixedly connected to the side of the push rod 31 to play an auxiliary supporting role. A plurality of through-holes 33 are evenly opened inside the side of the push rod 31, and the threaded rod 22 is movably connected inside the through-holes 33. The side of the push rod 31 is movably connected to a diagonal support rod 35, and the side of the diagonal support rod 35 is movably connected to a plurality of auxiliary rods 34. One end of the auxiliary rod 34 is movably connected to the side of the push rod 31, and the bottom surface of the diagonal support rod 35 is fixedly connected to a ground nail 36.

[0031] The length of the push rod 31 matches the height of the tall formwork 1, and the reinforcement plate 32 is arranged in the gap area of ​​the adjacent modular fixing units 2. The threaded rod 22 passes through the through hole 33 of the push rod 31 to realize the linkage between the modular fixing unit 2 and the side support unit 3. The push rod 31 forms a guided moving trajectory with the assistance of the limit frame 26. The diagonal support rod 35 and the auxiliary rod 34 on its side are both arranged on the side of the reinforcement plate 32. The diagonal support rod 35 and the auxiliary rod 34 are distributed on the side of the reinforcement plate 32 according to the triangular topology layout, forming a stable anti-lateral displacement support system, further enhancing the stability of the lateral support of the tall formwork 1.

[0032] In this embodiment, push rods 31 cooperate with limit frames 26 to connect modular fixing units 2 and lateral support units 3, allowing reinforcement plates 32 to adhere closely to the side surfaces of tall formwork 1. Diagonal braces 35 and auxiliary rods 34 form a dual-redundant support framework. The geometric stability of the triangular structure enables multi-path transmission of lateral support force, ultimately forming a composite reinforcement system that meets the engineering stability requirements of tall formwork 1.

[0033] The following is a detailed description of the working principle of the tall formwork support frame with enhanced lateral stability.

[0034] like Figure 1-5 As shown, through the cooperation of multiple modular fixing units 2, multi-stage fixation of the tall formwork 1 is achieved, ensuring that the tall formwork 1 has strong stability as a whole. At the same time, the side support units 3 are connected to the modular fixing units 2, and the side support units 3 are fixed by the modular fixing units 2. At the same time, the internal components of the side support units 3 form a multi-point supported triangular frame on the side of the tall formwork 1, further strengthening the overall support strength of the tall formwork 1;

[0035] After the connecting rod 23 and the threaded rod 22 are coaxially assembled, the limit block 25 is installed on the outside of the threaded rod 22 according to the preset phase difference. After the adjacent support components are riveted by the clamping block 29, they are tightened twice by the limit bolt 24 to enhance the transverse shear resistance. The threaded rod 27 is tightened and pre-tightened by the bolts on its surface to form a multi-level reinforcement system. The overall rigidity of the tall template 1 is enhanced by coordinating the equidistantly distributed support units.

[0036] Push rods 31 form a surface-to-surface connection with modular fixing units 2 via limit frames 26, while reinforcement plates 32 adhere closely to the side surfaces of tall formwork 1. Diagonal braces 35 and auxiliary rods 34 form a dual-redundant support framework. The geometric stability of the triangular structure enables multi-path transmission of lateral support force, ultimately forming a composite reinforcement system that meets the engineering stability requirements of tall formwork 1.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
