Description

Technical Field

[0001] The utility model relates to the technical field of concrete pipe concrete, in particular to a concrete pipe concrete with a bottom. Background Art

[0002] Concrete pipes are pipes made of concrete or reinforced concrete and used to transport fluids such as water, oil, and gas. They can be categorized into four types: plain concrete pipe, ordinary reinforced concrete pipe, self-stressed reinforced concrete pipe, and prestressed concrete pipe. Some concrete pipes have bottoms, but manufacturing these pipes presents several challenges.

[0003] The existing production process for concrete pipes with bottoms primarily relies on core mold vibration. Because these concrete pipes lack a steel cage, the concrete hasn't set when they're demolded, leaving the bottom unsupported and prone to falling. If demolding is performed only when the concrete is semi-set, the concrete easily adheres to the mold, making it difficult to remove, and resulting in low production efficiency. Therefore, technological innovation and design optimization are needed to optimize concrete pipes with bottoms. Utility Model Content

[0004] The existing production process of concrete pipes with bottoms is mainly carried out by vibrating the core mold. Since there is no steel cage inside this type of concrete, the concrete has not solidified when the pipe is demoulded, and the bottom of the pipe has no support and is easy to fall off. If the concrete is demoulded when it is semi-solidified, the concrete will easily stick to the mold and will not be easy to separate, and the production efficiency will be low. In order to solve the above problems, the embodiment of the present application provides concrete pipes with bottoms. By setting a pressure plate, the top of the concrete material can be flattened to avoid inconsistent bottom thickness of the concrete pipes with bottoms. At the same time, by setting a pad and a steel mesh, the problem of the bottom of the concrete pipe falling easily and the bottom of the concrete pipe being difficult to demould can be effectively solved, thereby improving the yield rate and production efficiency.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] Concrete pipe with bottom, including:

[0007] The core mold is provided with a supporting plate on the outside, an outer mold is provided on the top of the supporting plate, and an insert is fixed on the top of the supporting plate between the outer mold and the core mold.

[0008] In a possible implementation, an upper plate is provided on the top of the outer mold, and the upper plate is fixedly connected to the outer side of the outer mold, so that the upper plate facilitates lifting the outer mold.

[0009] In a possible implementation, a pad is provided on the top of the core mold. The pad has the same diameter as the core mold. The pad prevents the concrete from directly contacting the core mold and causing the concrete to adhere to the top of the core mold.

[0010] In a possible implementation, the space between the outer mold and the core mold is filled with concrete material, which forms a concrete pipe after cooling.

[0011] In a possible implementation, a steel mesh is provided on the top of the base plate. The steel mesh is located in the concrete material. The steel mesh can provide support to the bottom of the concrete pipe to prevent the bottom of the concrete pipe from collapsing during demoulding.

[0012] In a possible implementation, the diameter of the steel mesh is larger than the diameter of the core mold, and the diameter of the steel mesh is smaller than the inner diameter of the outer mold, which can better support the bottom of the concrete pipe.

[0013] In one possible implementation, a pressure plate is provided on the top of the upper plate, and a vent is provided on the core mold. Air is ventilated through the vent to release negative pressure. The diameter of the pressure plate is equal to the inner diameter of the outer mold, which facilitates flattening the concrete material.

[0014] In a possible implementation, two sides of the insert are tightly fitted with the outer mold and the core mold respectively, which is conducive to forming a notch on the concrete pipe.

[0015] In summary, the present invention has at least one of the following beneficial technical effects:

[0016] 1. The top of the concrete material can be flattened by the pressing plate to avoid inconsistent bottom thickness of the concrete in the production of bottom concrete pipes;

[0017] 2. At the same time, the pad and steel mesh can effectively solve the problem of easy falling of the bottom of the concrete pipe and the difficulty of demoulding the bottom of the concrete pipe, thereby improving the yield rate and production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solution of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The instrument placement rack involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] This embodiment introduces the specific structure of the concrete pipe with bottom. Figures 1-4 As shown, the concrete pipe with bottom includes:

[0026] Concrete pipe with bottom, including:

[0027] The core mold 6 is provided with a supporting plate 5 on the outside, an outer mold 3 is provided on the top of the supporting plate 5, and an insert 4 is fixed on the top of the supporting plate 5 between the outer mold 3 and the core mold 6.

[0028] When demoulding is required, an upper plate 1 is provided on the top of the outer mold 3 , and the upper plate 1 is fixedly connected to the outer side of the outer mold 3 , so that the upper plate 1 is convenient for lifting the outer mold 3 .

[0029] Before pouring the concrete material 9 , a pad 2 is provided on the top of the core mold 6 . The diameter of the pad 2 is the same as that of the core mold 6 . The pad 2 prevents the concrete from directly contacting the core mold 6 and causing the concrete to adhere to the top of the core mold 6 .

[0030] It is worth noting that the space between the outer mold 3 and the core mold 6 is filled with concrete material 9, which forms a concrete pipe after cooling.

[0031] When the bottom of the concrete pipe lacks support, a steel mesh 10 is provided on the top of the pad 2. The steel mesh 10 is located in the concrete material 9. The steel mesh 10 can provide support to the bottom of the concrete pipe to prevent the bottom of the concrete pipe from collapsing during demoulding.

[0032] At the same time, the diameter of the steel mesh 10 is larger than the diameter of the core mold 6, and the diameter of the steel mesh 10 is smaller than the inner diameter of the outer mold 3, which can better support the bottom of the concrete pipe.

[0033] When the top of the concrete material 9 needs to be flattened, a pressing plate 8 is provided on the top of the upper plate 1, and a vent hole 7 is opened on the core mold 6. Air is ventilated through the vent hole 7 to release the negative pressure. The diameter of the pressing plate 8 is equal to the inner diameter of the outer mold 3, which is convenient for flattening the concrete material 9.

[0034] In addition, the two sides of the insert 4 are tightly fitted with the outer mold 3 and the core mold 6 respectively, which is conducive to forming the notch on the concrete pipe.

[0035] The staff first aligns the center of the pallet 5 with the core mold 6, fixes the insert 4 on the pallet 5, then moves the outer mold 3 and the upper plate 1 vertically downward to a fixed position, and finally places the pad 2 and the upper end of the mold core to complete the assembly of the production mold. The core mold 6 then begins to vibrate, and at the same time, concrete material 9 is filled into the cavity between the outer mold 3 and the core mold 6, and then the pressing plate 8 begins to press down to compact the concrete. Manually remove a portion of the concrete at the top of the core mold 6, then place the steel mesh 10, and then backfill the concrete, and compact the concrete again using the pressing plate 8. Move the upper plate 1 and the outer mold 3 vertically upward to separate the product from the outer mold 3, move the pallet 5 with the insert 4 and the product upward a short distance, then vibrate the bottom of the product to separate the pad 2 from the product, and then move the pallet 5 upward to completely separate the product from the core mold 6, and then remove the insert 4 from the pallet 5. Then, move the pallet 5 and the product out of the production machine to complete production.

[0036] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
