Embodiment Construction
[0035] Such as Figure 1-3 As shown, a cast-in-place wall groove mold that is easy to remove the mold is used for pouring the groove on the cast-in-place wall 1, including a long strip mold 31 with a polygonal cross section, and the strip mold 31 is embedded in the to-be-cast In the cast-in-place wall 1, and one side is flush with the wall surface of the cast-in-place wall 1 to be poured; the strip mold 31 is buried in the edge of the cast-in-place wall 1 to be poured inward, and the depression is along the length direction of the rib filled with a buffer tube 32;
[0036] In actual use, the ribs at both ends of the strip mold 31 have little influence, and the buffer tube 32 may not be provided.
[0037] The material of the buffer tube 32 is an elastomer material, and is connected with the strip mold 31 through a connector that can be pulled apart along the demoulding direction of the strip mold 31, so that the buffer tube 32 is separated from the strip mold 31 when demouldin...

The invention relates to a mold for a wall, and discloses a cast-in-place wall groove mold easy to disassemble. The cast-in-place wall groove mold is used for pouring a groove on a cast-in-place wall, and comprises a strip mold with a polygonal cross section, the strip mold is embedded in the cast-in-place wall to be poured, and the edge of the strip mold in concrete is recessed inwards; the sunken part is filled with a buffer tube in the length direction of the edge; and the buffer tube is made of an elastomer material and is connected to the long-strip mold through a connecting piece which can be pulled open along the mold stripping direction of the long-strip mold. In the cast-in-place wall groove mold, during concrete pouring, the buffer pipe bears all bond stress and adhesion at the edge position and is separated from the long-strip mold during mold removal so that the long-strip mold can be easily pried out and cannot be damaged during mold removal, thus the long-strip mold can be recycled, meanwhile, the buffer tube which is severely adhered and wrapped by concrete can be pinched out from the wall in a pulling deformation mode for turnover use, and therefore the use cost is reduced.
Description
technical field [0001] The invention relates to a mold for walls, in particular to an easy-to-remove cast-in-place wall groove mold and a pouring method. Background technique [0002] For the sake of aesthetics or protection of pipelines, some pipelines need to be buried in the wall during residential construction, so it is necessary to open grooves on the wall. The most common wall grooves are fire pipe grooves for the arrangement of fire pipes. [0003] For masonry walls, since all parts of the wall are relatively uniform and there is no skeleton, it is allowed to open grooves after the wall construction is completed. However, for cast-in-place concrete walls with a reinforced skeleton, slotting after the wall is built may damage the reinforcement cage of the wall and cause serious damage to the wall. Therefore slotting on the cast-in-place concrete wall at present adopts the positive mold to carry out when pouring the body of wall. [0004] The current wall grooves usu...
