[0034] In order to facilitate the understanding of the disc buckle frame beam bottom mold support device provided by the embodiments of the present application, first of all, the application scenario is explained. With the rapid development of the construction industry, high-rise and large-span buildings are constantly emerging, and the requirements for formwork support technology are also becoming higher and higher. The traditional beam bottom mold support method often has problems such as complex structure, difficult installation, poor support stability, etc., and cannot meet the needs of modern construction. The disc buckle frame formwork system, as a common formwork support method, is widely used in various construction projects. However, the existing beam bottom mold support system often uses complex structure connection and adjustment, and the installation process is complicated, which requires a lot of time and manpower. At the same time, due to the large number of components, errors are easy to occur during installation, affecting the stability of the support. There are limitations in support stability and carrying capacity, especially under large-span and heavy-load conditions, which is prone to support failure risk. Moreover, the existing beam bottom mold support system is often designed for specific projects, lacks universality and flexibility, and is difficult to meet the needs of different projects, does not have flexible turnover use, and increases construction cost. In view of this, the present application provides a disc buckle frame beam bottom mold support device, which reduces the overall components, has a simple and easy-to-operate assembly process, speeds up the construction process, flexibly copes with different beam bottom mold support construction conditions, effectively reduces the risk of support failure, and improves construction safety.

[0035] Reference Figure 1 and Figure 2 As shown in the present application, the disc buckle frame beam bottom mold support device provided by the embodiments comprises a plurality of disc buckle frame bodies arranged between the bottom plate 10 and the beam bottom mold 20; the plurality of disc buckle frame bodies adopt a plurality of rod bodies such as disc buckle vertical rods 40, horizontal pipes 30 and inclined braces, which are connected to form a whole and are fully arranged between the bottom plate 10 and the beam bottom mold 20 to achieve stable support effect, which are all prior art known to those skilled in the art and will not be described in detail here.

[0036] In the present application, each row of disc-shaped frames at the bottom of the beam bottom formwork 20 is equipped with a support adjustment device 60. The support adjustment device 60 is easy to install, has good stability, and has strong support interchangeability. It is prefabricated in the factory and installed on site.

[0037] Specifically, the support and adjustment device 60 includes: a split channel steel joist, a connector 65 clamped and fixed at any position between the channel steel joists, a screw sleeve assembly 66 plugged into the connector 65, and a support assembly threadedly connected to the screw sleeve assembly 66. The channel steel joist, as an important support component in this application, is made of channel steel with a thickness of at least 8 mm. The channel steel joist can be stably connected to the buckle frame, thereby ensuring good limit installation performance.

[0038] Each row of the truss frames consists of two opposing truss posts 40 and a plurality of transverse tubes 30 connected along the height of the two truss posts 40. Adjustment discs 42 for supporting channel steel joists are symmetrically mounted on the two truss posts 40. High-strength truss posts 40, transverse tubes, and diagonal braces are used to enhance support strength.

[0039] In addition, the channel steel joists are connected by a plurality of bolt assemblies 64. The connector 65 has a positioning ring 652 that fits the top and bottom planes of the channel steel joist. The screw sleeve assembly 66 is rotatably connected to the top of the connector 65 and is used to adjust the support force of the support assembly 68. As can be seen, the support adjustment device 60 of the present application has the ability to move along the length of the channel steel joist and adjust the height of the support force 68, thereby expanding the adjustment range, allowing flexible installation matching and high versatility.

[0040] In order to better match the jacking assembly, the bottom of the beam bottom formwork 20 is cross-intersected with a beam bottom keel, and the support adjustment device 60 presses and connects the beam bottom keel. Through multi-point support, the risk of support failure is reduced. The beam bottom keel includes: a main keel 70 arranged along the length direction of the beam bottom formwork 20, and a secondary keel 50 located above the main keel 70 and cross-intersecting with the main keel 70; wherein, the jacking assembly presses the main keel 70. Both ends of the secondary keel 50 are connected to the two disc-shaped uprights 40 through pipe clamps 41. The connection performance is stable and provides reliable support force. The secondary keel 50 is connected to the two disc-shaped uprights 40, and the main keel 70 applies a jacking force 68 to the secondary keel 50 through the jacking assembly, thereby achieving stable support for the beam bottom formwork 20.

[0041] The simple structure of the channel steel support beam combined with the disc buckle vertical rod 40 reduces the number of components, making the installation process more convenient. At the same time, the factory prefabricated support adjustment device 60 can adapt to different sizes of beam bottom mold 20, further simplifying the installation steps. This design not only improves the construction efficiency, but also reduces the error rate in the installation process, ensuring the stability of the support.

[0042] In combination Figure 3 and Figure 4 As shown in, the channel steel support beam includes two channel steels, which are defined as the first channel steel 61 and the second channel steel 62 for ease of understanding. Both the first channel steel 61 and the second channel steel 62 are U-shaped channel steels, and the opening directions of the first channel steel 61 and the second channel steel 62 are opposite to each other. High-strength channel steel is used as the support beam to improve the overall support strength. At the same time, the first channel steel 61 and the second channel steel 62 are both provided with a plurality of through holes 63 for the bolt assembly 64 to pass through along the length direction. The installation method is more convenient. And when assembling the connecting piece 65 at any position, the bolt assembly 64 can be avoided.

[0043] The top support assembly in the present application includes a threaded rod 67 and a top support 68 connected to the top end of the threaded rod 67. The threaded rod 67 is threadedly connected with the screw sleeve assembly 66. The top support 68 is provided with a limiting gap for supporting the main ridge 70. The threaded top support 68 reduces the risk of support failure. By adjusting the gap position, the main ridge 70 is supported and limited, and after the main ridge 70 supports the secondary ridge 50 to a certain degree, the secondary ridge 50 is locked by the pipe clamp 41, thereby realizing multi-point support.

[0044] As can be seen, by optimizing the support structure and using high-strength channel steel and disc buckle vertical rod 40, the stability and carrying capacity of the support adjustment device 60 are significantly improved. The cooperation of the channel steel support beam and the disc buckle vertical rod 40 makes the support adjustment device 60 more stable and can bear greater load. This design effectively reduces the risk of support failure and improves construction safety. And using the modular and standardized design concept makes the support adjustment device 60 have better applicability and flexibility. The customized support adjustment device 60 can be adjusted according to the size and shape of different beam bottom molds 20, and can adapt to various complex construction environments. This design makes the present application can be widely used in various construction projects, improves its market competitiveness.

[0045] In order to embody the modularization and standardization design, the connecting piece 65 in the application comprises a vertical pipe 651; the vertical pipe 651 is connected with at least two positioning rings 652 in the height direction, the spacing between the two positioning rings 652 is the same as the height of the vertical section of the channel beam; the top end of the vertical pipe 651 penetrates the upper positioning ring 652 to form an axial connection part 653 which is rotationally connected with the screw sleeve assembly 66. The overall structure is simple, the installation method is simple, and it has flexible usability.
