Description

Technical Field

[0001] The utility model relates to the technical field of grouting moulds, in particular to a prefabricated shear wall grouting mould capable of multi-point filling. Background Art

[0002] Precast shear walls are factory-fabricated concrete shear wall components, typically consisting of inner and outer blades, possibly with an insulation layer sandwiched between them. These components are connected to the cast-in-place shear wall edge components at the construction site via pre-reinforced steel. Their base is connected to the pre-reinforced steel of the underlying precast shear wall via a steel grouting sleeve. Precast shear walls offer advantages such as high energy efficiency, environmental friendliness, cost reduction, and improved residential functionality and performance. They are suitable for both industrial and residential construction, particularly high-rise buildings. Precast shear wall structures offer excellent practicality, require minimal on-site construction, are less affected by the inconveniences of high-rise transportation, and are constructed quickly, meeting modern commercial trends. Precast shear walls are often produced using mold-based grouting. Traditional grouting methods, typically from top to bottom, result in inconsistent setting rates between the upper and lower layers, ultimately leading to structural deficiencies. To address this, a precast shear wall grouting mold with multi-point filling has been proposed.

[0003] For example, a mold for prefabricated shear wall production disclosed in the authorization announcement number CN220807869U includes a lower mold body and an upper mold body connected and covering the top of the lower mold body. The lower mold body is provided with a plurality of reinforcement waist holes spaced apart along its length. The plurality of reinforcement waist holes pass through the top of the lower mold body and extend toward the vertical direction of the lower mold body. The two end frame limiters are installed between the two lower mold bodies.

[0004] While it achieves the goal of hoisting the pre-tied steel cage along multiple reinforcement waist holes between the two lower mold bodies, reducing the inconvenience and time-consuming problems caused by on-site reinforcement, during the demoulding process, the upper mold body is removed to allow the prefabricated part to be lifted out vertically. The operation is simple and convenient, and the operation process requires less manpower. At the same time, when the mold is reassembled, the time for positioning, leveling and straightening is reduced, thereby improving production line efficiency, increasing reuse rate, and thus reducing project costs;

[0005] However, the problem that the existing grouting mold is not conducive to convenient and rapid assembly of the mold and insertion of steel bars during use, is not conducive to uniform filling and grouting of concrete at multiple points, and affects the uniformity of grouting. Utility Model Content

When the grouting is completed and cooled and formed, the limit pin is pulled out from the inside of the interlocking frame, and the upper formwork is moved upward. The upper formwork can then drive the interlocking frame to separate from the bottom frame, and the long side panels and short side panels can be removed to separate the concrete shear wall from the surface of the lower formwork.
