Problems solved by technology

[0004] At present, the steam curing methods for concrete components mainly include: prefabricated components cover film heating, curing tower curing, etc. These methods have disadvantages, cover film heating takes up a large area, consumes a lot of energy, and has low production capacity; curing tower maintenance has not been solved well The link of assembly line maintenance and maintenance has become a bottleneck restricting production capacity, and the equipment required is relatively large in investment and energy consumption

Embodiment 1

[0037] Such as Figure 1-2As shown, a three-dimensional maintenance tunnel for prefabricated concrete components includes a long tunnel 3 surrounded by a base 1 and an outer shell 2. The outer shells 2 around the tunnel 3 are all made of thermal insulation materials or contain thermal insulation materials. structure, on both sides of the tunnel 3, there are multi-layer tracks 4 running through the tunnel 3. The track 4 is a continuous track, just like the crane beam of the factory building, hanging on the walls on both sides of the tunnel 3. For steam heating equipment, both ports of the tunnel 3 are provided with openable and closable isolation doors 8 for the mold table 7 carrying the prefabricated parts to pass through, and the inside of the tunnel 3 is a closed steam curing room 10 containing multi-layer tracks. According to the production requirements, the number of layers of the track 4 and the length of the track 4 are designed to facilitate the sliding of the concrete ...

Embodiment 2

[0041] refer to Figure 3-5 As shown, it is another specific embodiment of the present invention, which is basically the same as Embodiment 1, except that a preheating chamber 9 that can automatically communicate with the steam curing chamber 10 is provided at the entrance end of the tunnel 3, and the preheating Chamber 9 is a relatively low-temperature area, and the completed prefabricated concrete member and mold table combination 7 need not be left to stand for initial setting and final setting, but are directly pushed into the preheating chamber 9, which can accelerate initial setting and final setting in winter. The waste heat of the steam curing room 10 can be used to further utilize energy and save energy, and the prefabricated components can be heated up slowly through low-temperature preheating to better ensure the quality; between the steam curing room 10 and the preheating room 9, there is an automatic opening and closing Isolation door 8, the bottom of the isolatio...

Embodiment 3

[0046] refer to Figure 6-7 As shown, it is another specific embodiment of the present invention, which is basically the same as that of Embodiment 2, except that: in the steam curing chamber 10, a plurality of isolation chambers is arranged horizontally to isolate the steam curing chamber 10 into a plurality of cavities. Plate 12, one end of the isolation plate 12 is provided with mutually staggered steam channels 13, the steam channels 13 on two adjacent isolation plates 12 are mutually staggered, and the steam curing room 10 is horizontally divided into multiple chambers by the isolation plate 12 , so that the hot steam is blocked by the horizontal partition of the isolation plate 12 during the rising process, so that the steam flows along the horizontal track direction, and then rises through the steam channel 13, effectively ensuring that the temperature in the steam curing room 10 is uniform, and ensuring that the concrete components and the mold table Combo 7 quality. ...

Abstract

The invention discloses a stereoscopic maintenance tunnel for precast concrete members. The stereoscopic maintenance tunnel comprises a long-bar-shaped tunnel body surrounded by a base and a shell. A plurality of layers of tracks penetrating through the tunnel body are distributed at the two sides of the inside of the tunnel body. Heating equipment used for generating steam is arranged inside the tunnel body. Two end openings of the tunnel body are both provided with openable and closeable isolation gates allowing mold platens carried with the precast members to pass through. A closed steam curing chamber containing a plurality of layers of tracks is installed inside the tunnel body. The stereoscopic maintenance tunnel for the precast concrete members is reasonable in structural design, capable of achieving assembly-line-type maintenance, high in maintenance amount, capable of saving energy and high in efficiency.

Description

technical field [0001] The invention relates to the production field of prefabricated concrete components in building industrialization, more specifically, it relates to a three-dimensional maintenance tunnel for prefabricated concrete components. Background technique [0002] As a structural form in line with industrial production methods, prefabricated concrete structures have the advantages of fast construction speed, low labor intensity, less noise pollution and wet work, and easy control of product quality. Prefabricated building construction can effectively save resources and energy, improve the utilization rate of materials in achieving building energy conservation and structural performance, reduce the number of on-site construction labor, reduce construction waste and reduce the adverse impact of construction on the environment, and improve the overall quality of the building and performance. It can be seen that the promotion of prefabricated concrete structures is...
