Description

Technical Field

[0001] This application relates to the field of building construction support, and in particular to an independent quick-release support structure for post-cast strips. Background Technology

[0002] In the field of building construction, the setting of post-pouring strips is of great significance for ensuring the integrity and stability of concrete structures. It can effectively alleviate the shrinkage stress generated by concrete during the setting process, thereby reducing the risk of structural cracks and improving the safety and durability of buildings. This technology has been widely promoted and applied in the construction industry, making an important contribution to improving the quality of building projects.

[0003] In previous construction processes, to meet the requirement that the concrete pouring at the post-pouring strip should be later than that on both sides, independent supports were usually required. For such independent support structures, the common practice was to use ordinary steel pipe scaffolding for support, and to ensure the stability of the support structure by making complex connections and fixations between the uprights and horizontal bars. Another method was to use a disc-lock scaffold, which uses disc-lock nodes to connect the uprights and horizontal bars. When dealing with the support at the junction of the post-pouring strip, the traditional method was to tightly connect the formwork and joists above the support to the support structure. This connection method made it difficult to remove the formwork and joists while keeping the support stationary. Construction workers usually had to spend a lot of time and effort to dismantle them, and even had to use some special tools and methods to overcome the tightness of the connection.

[0004] However, these existing technologies have significant drawbacks. The formwork and joists above the supports at the conventional post-cast strip junction cannot be easily removed while the supports remain stationary. This not only hinders cleaning at the post-cast strip, making it difficult to remove debris and dust, affecting the quality of subsequent concrete pouring, but also impedes the reuse of formwork. The inability to promptly remove and reuse formwork and joists leads to low material utilization efficiency, increasing rental costs and construction costs. Furthermore, altering the support structure to remove formwork and joists causes changes in stress, easily leading to serious problems such as concrete deformation and cracking, threatening the safety and stability of the building structure. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides an independent quick-release support structure for post-pouring strips. It has a simple structure, low manufacturing cost, and is easy to install and disassemble. It can effectively support and position the uprights, flexibly adjust the height, prevent the vertical deflection of the connecting plate, facilitate the support of the keel, and improve the stability and applicability of the support structure.

[0006] This application is achieved through the following technical solution: A post-cast strip independent quick-release support structure includes: The uprights are arranged vertically in the construction area of ​​the post-pouring strip, and the uprights are provided with connecting channels arranged along the length direction; A horizontal bar is a horizontally connected bar between adjacent vertical bars to support and position them. A threaded push rod is slidably connected in the connecting channel; An adjusting sleeve is threadedly connected to a threaded push rod, which abuts against the connecting channel via the adjusting sleeve. The support has a mounting groove at its lower end, and the threaded push rod is fixed in the middle of the mounting groove; The connecting plate is detachably connected in the mounting groove, and the root of the connecting plate abuts against the side wall of the threaded top rod to prevent the connecting plate from deflecting in the vertical direction. The lower end of the support beam has a snap-fit ​​groove that matches the connecting plate, and the side wall is provided with a support plate for supporting the keel.

[0007] By adopting the above technical solution, the uprights and horizontal bars form a support system to support and position the construction area of ​​the post-pouring strip. The threaded top rod slides in the connecting channel and is positioned by abutting through the adjusting sleeve. The height can be adjusted so that the quick-release top support structure is flush with the formwork on both sides. The support is fixed to the threaded top rod through the installation groove. The connecting plate is detachably connected in the installation groove and its root abuts against the side wall of the threaded top rod to prevent it from deflecting vertically and to ensure connection stability. The support beam is adapted to the connecting plate through the snap-fit ​​groove. Its side wall support plate can support the keel. The overall structure is simple and the construction is convenient. While keeping the support structure stationary, the formwork and keel on both sides can be quickly and conveniently removed, the post-pouring strip can be cleaned in time, and the material turnover can be accelerated, reducing rental costs.

[0008] Optionally, the side wall of the mounting groove is provided with a connecting hole, and the connecting plate is connected to the mounting groove by a fixing pin provided in the connecting hole; the connecting plate is provided with a positioning hole that matches the fixing pin.

[0009] By adopting the above technical solution and using fixing pins for fixation, the connecting plate and the mounting groove can be detached, allowing the template and keel to be quickly and conveniently removed. This facilitates timely cleaning of the post-pouring strip, speeds up material turnover, reduces rental costs, and ensures accurate installation of the connecting plate by cooperating with the positioning holes and fixing pins.

[0010] Alternatively, the bracket is composed of two parallel fixed plates, and the upper end of the mounting groove has an open space that allows the connecting plate to protrude from the bracket; the connecting hole has an oval structure and is arranged vertically on the fixed plate; the end of the fixing pin is threaded with a locking nut.

[0011] By adopting the above technical solution, the two parallel fixed plates ensure structural stability, the oval connecting holes allow for vertical adjustment of the connecting plate position, and the threaded connection of the fixing pin end with a locking nut ensures a secure connection between the connecting plate and the bracket. The whole structure is easy to install and disassemble, and the connecting plate position can be flexibly adjusted to adapt to concrete slab pouring structures with stepped structures.

[0012] Alternatively, channel steel can be used to make the support. Channel steel has a certain strength and stability, which can provide a solid support for the support. The threaded top rod is fixed to the support by welding, so that the two are firmly connected, ensuring the stability and reliability of the entire support structure.

[0013] Optionally, the end of the bracket that connects to the beam is arranged at an angle.

[0014] By adopting the above technical solution, the support plate of the beam can be extended to abut against the threaded top rod, reducing the support blind spot.

[0015] Optionally, the support plate is provided with a sliding groove arranged along the length direction, and a positioning bolt is provided in the sliding groove.

[0016] By adopting the above technical solution, the support plate is provided with a sliding groove arranged along the length direction and a positioning bolt is set in the sliding groove, which can adapt to the keel with different arrangement spacing. After the keel spacing is determined, the positioning bolt is tightened to facilitate the fixing of the keel end.

[0017] Optionally, the side wall of the adjusting sleeve is provided with a toggle handle.

[0018] By adopting the above technical solution, a toggle handle is provided on the side wall of the adjusting sleeve, which makes it easier to rotate the adjusting sleeve and adjust the position of the threaded top rod in the connecting channel to adjust the height of the support structure, so that the quick-release top support structure is flush with the templates on both sides, making it easy to quickly and conveniently remove the templates and keel.

[0019] Optionally, a triangular reinforcing plate is provided between the support plate and the side wall.

[0020] By adopting the above technical solution, the support plate of the independent quick-release support structure of the post-pouring strip is more stable, which enhances the stability of the entire support structure, helps to keep the stress of the support structure unchanged, and facilitates the quick and easy removal of the formwork and keel.

[0021] Optionally, the support plate is provided with an auxiliary support plate, and the auxiliary support plate is provided with oval fixing holes arranged along the length direction.

[0022] By adopting the above technical solution, the support height of the auxiliary support plate beam on the keel support surface is adjusted to accommodate the total height of different specifications of wooden formwork and keel, ensuring that the formwork and the upper surface of the quick-release top support structure are flush, and the support plate is fixed after the height is adjusted.

[0023] The connecting plate is made of rectangular steel pipe; the supporting beam is made of C-shaped steel.

[0024] By adopting the above technical solution, using rectangular steel pipes to make connecting plates and C-shaped steel to make support beams, the independent quick-release support structure of the post-pouring strip can be made simple and convenient to construct.
