Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, and more specifically to a combined mold for the construction of a shallow circular grain outlet ramp. Background Technology

[0002] In the construction of shallow circular silos, the construction quality of the grain outlet ramp is crucial to the structural stability of the entire silo and the safety of grain storage. Traditional techniques typically involve on-site erection of wooden formwork, a cumbersome process requiring multiple assembly and disassembly of the formwork, consuming significant manpower and time, resulting in low construction efficiency. Furthermore, during concrete pouring, the formwork's support structure is not sufficiently stable, making it prone to deformation and affecting the quality of the ramp's formation. Additionally, dismantling the grain outlet ramp formwork easily causes damage, and most materials are only used once, unable to be reused, leading to substantial material waste.

[0003] Therefore, there is an urgent need for a mold that can solve the problems of low construction efficiency, poor concrete forming effect and material waste caused by the traditional wooden formwork used to support the inverted sill of the shallow round grain outlet. Utility Model Content

[0004] In view of this, the present invention provides a combined mold for the construction of the inverted sill at the grain outlet of a shallow circular silo. The steel box has high overall rigidity, which avoids deformation and displacement of the inverted sill at the grain outlet of the shallow circular silo due to the pressure of poured concrete, thereby ensuring the quality of concrete pouring and the forming effect. The combined mold is made of steel material, which avoids damage during disassembly and can be reused.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A combined mold for constructing a reverse sill at the grain outlet of a shallow circular silo includes an outer steel mold box, an inner steel mold box, and connecting parts;

[0007] The inner mold steel box is coaxially located in the inner cavity of the outer mold steel box, and there is a concrete pouring gap between the outer wall of the inner mold steel box and the inner wall of the outer mold steel box; there are multiple connectors, and the two ends of the multiple connectors are detachably connected to the top of the inner mold steel box and the outer mold steel box respectively to fasten the inner mold steel box and the outer mold steel box.

[0008] The beneficial effects of this utility model are as follows: by connecting the inner and outer steel mold boxes with connectors, it is ensured that they will not be misaligned; by pouring concrete into the gap of the concrete pouring of the inverted sill, a shallow circular grain outlet inverted sill is formed; by using steel boxes, this utility model ensures the rigidity of the mold and prevents the quality and effect of concrete forming from being affected by deformation or damage of the mold during the concrete pouring process; moreover, the steel mold has high rigidity and strength, and can be reused repeatedly, avoiding the material waste caused by using wooden molds.

[0009] Preferably, the inner mold steel box has a first ear plate fixed to each of the four corners of its top inner wall, and the outer mold steel box has a second ear plate fixed to each of the four corners of its top outer wall; the number of connectors is four, and the two ends of the four connectors are respectively bolted to the first ear plate and the second ear plate. The bolted connection between the connectors and the first and second ear plates facilitates connection and disassembly, making it convenient for demolding concrete.

[0010] Preferably, the first ear plate is a square plate, and the second ear plate is an L-shaped plate, both of which have round holes; the connector is a flat iron, with anchoring holes corresponding to the round holes on both end plates; the threaded end of the locking bolt passes through the anchoring holes and the round holes and is tightened by a nut to connect the connector and the first or second ear plate. The connection is simple and reliable.

[0011] Preferably, the thickness of the flat iron is not less than 3mm. This ensures the rigidity of the connectors, prevents deformation of the connectors during concrete pouring that could affect the forming effect of the inverted curb, and also avoids relative displacement between the inner and outer mold steel boxes.

[0012] Preferably, handles are welded to the top outer wall of the outer mold steel box and the top inner wall of the inner mold steel box. The handles facilitate the installation and disassembly of the mold.

[0013] Preferably, the handle is made of round steel bent into shape. This method is easy to obtain and simple to manufacture.

[0014] Preferably, the outer mold steel box is a hollow square box formed by welding four steel plates end to end; the inner mold steel box is an inverted frustum-shaped hollow box formed by welding four steel plates end to end. The welding method ensures the airtightness of the steel boxes, preventing grout leakage during concrete pouring and ensuring the molding quality of the retaining wall concrete.

[0015] Preferably, the thickness of the steel plate is not less than 3mm. This ensures that the steel box has sufficient strength and rigidity and will not deform due to lateral compression from the concrete.

[0016] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a combined mold for the construction of the inverted sill of a shallow circular grain silo. It uses a steel box, eliminating the need to repeatedly make wooden boxes, reducing the amount of templates and labor, and saving construction costs. It is simple to manufacture and install, and the steel box has high overall rigidity, preventing the inverted sill of the grain outlet from deforming or shifting due to the pressure of poured concrete. At the same time, the use of a steel box can prevent damage when the mold is dismantled, improving the turnover rate of the mold. Attached Figure Description
