Embodiment 1

[0041] Referring to Fig. 1, the present embodiment provides a method for manufacturing a thin-walled pipe, including the following process steps:

[0042] S1: Prepare at least three material plates using the first slurry, and reserve corresponding notches on the material plates during preparation.

[0043] Specifically, refer to figure 2 , image 3 , using the first slurry 100 to prepare four material plates 200 . Each material plate 200 is a flat plate. During preparation, use the plate frame 300 to surround the outer contour of the material plate 200 on the flat ground 400, then lay a layer of first slurry 100 in the plate frame 300, and then lay reinforcing materials on the laid first slurry 100 500, and finally lay a layer of first slurry 100 on the reinforcing material 500, and level it. In this step, a reinforcing material 500 is provided to enhance the strength of the sheet 200 . The reinforcing material 500 can also be arranged in multiple layers, and can be laid ...

Embodiment 2

[0056] This embodiment provides a second method for manufacturing a thin-walled pipe, including the following process steps:

[0057] S1: using the first slurry to prepare a material plate, the material plate has at least two grooves parallel to the long end surface of the material plate, so that the material plate can be bent into a multi-block shape connected by a rib network through the grooves, Reserve a corresponding notch on the material plate during preparation.

[0058] Specifically, refer to Figure 7 , Figure 8 , using the first slurry 100a to prepare the material plate 200a, during preparation, use the plate frame 300a to enclose the outer contour of the material plate 200a on the flat ground 400a, and then lay a layer of the first slurry 100a in the plate frame 300a, and then Lay the reinforcing material 500a on the laid first slurry 100a, and finally lay a layer of the first slurry 100a on the reinforcing material 500a, and level it, and finally press the groov...

Embodiment 3

[0071] refer to Figure 13 , is the third embodiment of the thin-walled pipe provided by the present invention. The difference between this embodiment and the second embodiment lies in that the preparation process of the material sheet 200b is different. Depend on Figure 13 It can be seen from the figure that in this embodiment, when the material plate 200b is manufactured, the grooved molding strips are first inverted on the flat ground 400b, and then the first slurry 100b and the reinforcing material 500b are laid. Although this method is different from the first embodiment, the structure of the final formed material plate 200b is the same.

Abstract

The invention relates to the technical field of molding of building ventilation thin-wall pipelines, and provides a thin-wall pipeline and a manufacturing method thereof. The manufacturing method comprises the following process steps: making plates by using a first sizing agent, wherein corresponding recesses are preserved in the plates; hardening the plates; painting a second sizing agent in the recesses of the hardened plates and / or on the long end faces of the plates; enclosing the plates painted with the second sizing agent into a thin-wall pipeline, and connecting adjacent pipe walls through lap joint pieces arranged in corresponding recesses; hardening the second sizing agent to fixedly connecting the thin-wall pipeline into a whole. By adopting the method for manufacturing the thin-wall pipeline, a large quantity of steel dies do not need to be put into use, thereby greatly reducing the early-stage investment cost and bringing convenience to the production of thin-wall pipes of the same specification and model; meanwhile, reinforcing rib meshes can be arranged in the pipeline conveniently, and are prevented from exposing in a manufacturing process more reliably.

Description

technical field [0001] The invention relates to the molding technology of thin-walled ventilation pipes for buildings, and more specifically relates to a molding method for thin-walled ventilation pipes made of cement mortar. Background technique [0002] At present, there are four types of molding methods for polygonal cement mortar thin-walled pipes, including external moulding, internal moulding, external moulding, internal and external moulds, and mechanical extrusion molding. No matter what kind of existing pipe forming technology, there are problems such as large investment in pipe making molds, difficult deployment of reinforcement mesh, and difficulty in making pipe sockets. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and to provide a thin-walled pipe and its manufacturing method. The manufacturing method of the pipe is low in cost, convenient for the reinforcement mesh ...
