Description

Technical Field

[0001] This utility model relates to the field of concrete shaping mold technology, and more specifically, to a shaping mold for a conical concrete protective pier for the root of a pipe exiting the roof. Background Technology

[0002] In traditional building waterproofing construction, the flashing treatment at the root of pipes exiting the roof is a key seepage prevention node. Usually, it is necessary to pour a conical concrete protective pier to achieve structural self-waterproofing. Concrete molding molds are the core tools in the concrete forming process, and their development is closely related to the application of concrete materials and technological innovation in the construction industry.

[0003] The existing publication number, CN118596337A, discloses a concrete pipe pile for water conservancy construction and its shaping mold, relating to the field of pipe pile production technology, and particularly a concrete pipe pile for water conservancy construction, including a concrete pipe pile used for foundation reinforcement. The concrete pipe pile includes: a main component, including end plates fixed at both ends of the pipe body; a reinforcing component, including several annular ribs surrounding the outside of the pipe body, and reinforcing ribs at both ends of the pipe body; the interior of the pipe body is incorporating steel fibers and synthetic fibers; through a processing mechanism, the concrete pipe pile in the mold component can better fill the bottom and sidewalls of the mold component during the preparation process due to gravity, thereby improving the distribution and compactness of the concrete, which helps to reduce the generation of air bubbles; and also helps to tightly bond the concrete particles, improving the overall strength and durability of the concrete. The inventors discovered the following problems in the prior art during the development of this utility model: Existing concrete molding molds are usually assembled in sections using wooden or steel formwork, which has problems such as many formwork joints, poor precision, and easy damage during demolding. This results in large deviations in the geometric dimensions of the protective piers and uneven compaction, affecting the drainage slope and waterproofing effect. Therefore, a mold for a conical concrete protective pier for the root of roof-mounted pipes is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mold for a conical concrete protective pier for the root of the roof pipe, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for a conical concrete protective pier for the root of a roof-mounted pipe, comprising a mold body, wherein a cavity is formed in the middle of the mold body; a mold cover is installed in the middle of the mold body; a sealing plate is fixedly connected to the bottom of the mold cover; the surface of the sealing plate is in contact with the inner wall of the mold body; a feed hole is formed at the top of the mold cover; the feed hole penetrates the mold cover and the sealing plate; and a support is fixedly connected to the bottom of the mold cover.

[0006] Preferably, a conical cylinder is fixedly connected to the middle of the sealing plate; the conical cylinder is conical; and the top of the conical cylinder is fixedly connected to the shaping cover.

[0007] Preferably, the top of the mold body is fixedly connected with multiple limiting posts; the top of the shaping cover is provided with multiple positioning holes; and the limiting posts slide in the middle of the positioning holes.

[0008] Preferably, a fixing plate is installed on the top of the shaping cover; the top of the fixing plate has multiple slots; the limiting post protrudes from the slots in the fixing plate; multiple bolts are threaded onto the surface of the limiting post; the bolts are located on the top of the fixing plate.

[0009] Preferably, a piston is slidably connected to the middle of the feed hole; a top cover is fixed to the top of the piston; the top cover is located at the top of the shaping cover.

[0010] Preferably, a rope is fixedly connected to the top of the top cover; a fixing block is fixedly connected to the end of the rope; and the fixing block is fixedly connected to the top of the shaping cover.

[0011] Preferably, a base plate is fixedly connected to the bottom of the mold body; the top of the base plate has multiple threaded holes.

[0012] Preferably, the top of the base plate is fixed with thermal insulation cotton; the thermal insulation cotton is wrapped around the middle of the mold body.

[0013] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this mold for a conical concrete protective pier for the root of roof pipes is equipped with a mold cover, sealing plate, limiting post, and fixing plate. Through a combined sealing design, it achieves multiple sealing protections. The sealing plate uses an elastic rubber ring to seal between the mold body and the mold cover, reducing the joints between the finished concrete pouring. At the same time, because the central part of the mold body has a circular sealing structure, it can avoid the problem of uneven density, which would affect the waterproofing effect.

[0014] Compared with existing technologies, this mold for a conical concrete protective pier for the root of roof pipes is equipped with a piston, rope, etc., which can block the feed hole after pouring, so that the piston and the feed hole form a mechanical engagement. At the same time, the rubber ring in the middle of the piston is compressed and contacts the inner wall of the feed hole, achieving a seal in the middle of the mold body. This completely solves the problem of concrete loss caused by traditional sealing, and also facilitates the filling of grout in the middle of the mold body. Attached Figure Description
