Description

Technical Field

[0001] The present application relates to the technical field of supporting structures, and in particular to a supporting structure for a post-cast belt of a basement roof settlement. Background Art

[0002] Post-cast strips are temporary construction joints set up at the corresponding positions of the foundation slab, wall, and beam in accordance with the design or construction specifications to prevent harmful cracks that may occur in cast-in-place reinforced concrete structures due to uneven shrinkage or settlement. The post-cast strips require the support of formwork when tying steel bars, and then pouring concrete on both sides of the post-cast strips. After the concrete on both sides of the post-cast strips reaches the predetermined strength, the post-cast strips can be poured.

[0003] Patent "CN201921033359.3" proposes to support the side formwork by the top rods on both sides of the adjustment block, which is convenient for construction and has stable support. A spring is provided at the contact with the side formwork to prevent the supporting force of the side formwork from deteriorating when the volume of concrete changes; a screw rod and a lifting rod are provided on the adjustment block, and the lifting rod can be detachably connected to the mobile formwork, which is convenient for lifting and lowering the mobile formwork, thereby facilitating the cleaning of garbage from the gap formed by the mobile formwork and the bottom formwork.

[0004] However, in actual use, due to the large amount of water vapor and oxygen in the air, the screw will rust and the nut will not be able to be used normally. At the same time, some cement mortar will drip, which will also make the screw unusable. Utility Model Content

[0005] The present application proposes a basement roof settlement post-casting belt support structure to solve the problem that the screw rods may become unusable due to rust and dripping of cement mortar.

[0006] In order to achieve the above purpose, this application adopts the following technical solutions:

[0007] A basement roof settlement post-casting belt support structure, comprising two templates and steel bars, a fixing piece is arranged between the two templates, and a waterproof plate is fixedly installed on the upper ends of the two templates;

[0008] The fixing member comprises a rotating drum, both ends of the rotating drum are respectively threadedly connected with threaded rods, a pressing block is fixedly arranged at one end of the threaded rod away from the rotating drum, a bellows is arranged between one side of the pressing block and the outer wall of the rotating drum, an air pipe is installed on the outer wall of the rotating drum, and both ends of the outer wall of the rotating drum are respectively rotatably connected with support plates;

[0009] During use, first rotate the two threaded rods separately until the distance between the two pressing blocks is close to the distance between the two templates, then put the fixing part between the two templates, and then continue to rotate the pressing block until there is friction between the pressing block and the template, then rotate the drum until the predetermined effect is achieved and then stop the operation to complete the support. After use, it can be dismantled and recycled for reuse, which greatly improves the practicality and avoids a large amount of waste of wood.

[0010] As a preferred embodiment, the bellows is fixedly connected to the pressing block, the bellows is rotatably connected to the drum, and a sealing ring is provided between the bellows and the drum;

[0011] During use, the bellows can effectively prevent cement from falling onto the surface of the threaded rod, thereby avoiding affecting the use of the threads on the surface of the threaded rod. At the same time, it can also provide a good moisture-proof effect to prevent the threaded rod from rusting, thereby greatly improving the service life of the threaded rod.

[0012] As a preferred embodiment, the rotating drum is made of stainless steel, and an anti-slip sleeve is provided in the middle of the rotating drum; the anti-slip sleeve makes it easier for staff to hold the rotating drum.

[0013] As a preferred embodiment, the interior of the air pipe is filled with absorbent cotton, an air hole is opened on the side wall of one end of the air pipe located outside the drum, and the air pipe is threadedly connected to the drum;

[0014] During use, absorbent cotton is filled in the air pipe to prevent wet air from entering the interior of the drum and causing the threaded rod inside the air pipe to rust.

[0015] As a preferred embodiment, a limiting groove for use with a steel bar is provided at the lower end of the support plate, and anti-slip rubber is pasted in the limiting groove;

[0016] During use, the fixing piece is locked to the upper end of the steel bar by means of a clamping connection, which is convenient for the workers to install and disassemble.

[0017] As a preferred embodiment, a reflective film is pasted on the outer wall of the waterproof board, which serves as a warning to prevent workers from stepping on it.

[0018] Beneficial effects of this application:

[0019] 1. The basement roof settlement post-casting belt support structure is provided with a corrugated pipe, which effectively prevents cement from falling onto the surface of the threaded rod, thereby avoiding affecting the use of the thread teeth on the surface of the threaded rod. At the same time, it can also play a good moisture-proof effect and prevent the threaded rod from rusting, thereby greatly improving the service life of the threaded rod;

[0020] 2. The supporting structure of the cast-in-place belt after the basement roof settles completes the support by rotating the drum until the predetermined effect is achieved and then stops operating. After use, it can be dismantled and recycled for reuse, which greatly improves the practicality and avoids a large amount of waste of wood. BRIEF DESCRIPTION OF THE DRAWINGS
