Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a foldable double-layer in-situ concrete segment curing shed. Background Technology

[0002] Concrete segments are key precast components in underground engineering projects such as shield tunnels, and their quality directly affects the safety and durability of the tunnel. At the segment production or construction site, proper temperature and humidity curing of newly poured concrete segments is a crucial step in ensuring they reach their design strength and performance.

[0003] Currently, temporary curing sheds are typically erected to achieve in-situ curing at construction sites. However, many existing curing sheds have relatively fixed structures or are complex to build, making them difficult to move quickly between different work positions and reuse, thus failing to meet the flexible and efficient in-situ curing needs of construction sites.

[0004] More importantly, in order to achieve the required temperature for curing inside the greenhouse, existing technologies often use methods such as directly introducing hot steam into the greenhouse space or using heated blowers to blow hot air directly. This direct heating method, especially the direct blowing of hot air, can easily cause the surface moisture of the concrete segments to evaporate too quickly, creating a large temperature difference and humidity gradient between the inside and outside.

[0005] The resulting uneven shrinkage and thermal stress can cause cracks on the surface of the tunnel lining segments, severely affecting their durability and engineering quality. At the same time, traditional single-layer shed structures generally have poor insulation performance, resulting in rapid heat loss, high energy consumption, and difficulty in achieving a constant curing environment.

[0006] Therefore, this utility model proposes a foldable double-layer in-situ concrete segment curing shed to address the shortcomings of existing technologies. Utility Model Content

[0007] In view of the problems of inconvenient construction, concrete cracking, poor heat preservation and high energy consumption caused by direct heating in existing foldable double-layer in-situ concrete segment curing sheds, this utility model aims to provide a foldable double-layer in-situ concrete segment curing shed with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a foldable double-layer in-situ concrete segment curing shed, comprising: a telescopic storage component and a heat insulation component. The heat insulation component includes an inner shed and an outer shed. The inner shed is installed on the outside of the telescopic storage component, and the outer shed is fixedly connected to the outside of the inner shed and completely encloses it. An airtight heat-insulating cavity is provided between the inner shed and the outer shed, and an air inlet communicating with the airtight heat-insulating cavity is provided on the outer shed.

[0009] Preferably, the telescopic storage assembly includes a longitudinal support rod, a transverse support rod, and a vertical upright, which are connected by a three-way connector.

[0010] Preferably, the telescopic storage assembly further includes a base, the top of which is fixedly connected to the bottom of the vertical pole, and the side of which is fixedly connected to the longitudinal support pole.

[0011] Preferably, the maintenance shed further includes an intelligent adjustment component, which includes a heating blower, a pressure sensor, and a temperature sensor. The output end of the heating blower is adapted to and connected to the air inlet. The pressure sensor is installed on the top inner wall of the outer shed, and the temperature sensor is installed on the inner wall of the inner shed.

[0012] Preferably, the heat insulation component further includes a pneumatic safety valve disposed on the top of the outer canopy and a condensate drain installed on the surface of the outer canopy.

[0013] Preferably, the inner canopy is composed of a composite of glass fiber double-sided silicone coated cloth and aluminum silicate flame-retardant insulation cotton.

[0014] Preferably, the outer canopy is made of PE waterproof fabric.

[0015] This utility model has the following beneficial effects: 1. In this utility model, by setting up a telescopic storage component consisting of telescopic longitudinal support rods, transverse support rods and vertical uprights modularly connected by a three-way connector, the problem of fixed structure, large size and inconvenience for quick assembly, disassembly and transportation of the existing maintenance shed is solved, thus achieving the technical effect of quick installation, convenient storage and easy transportation.

[0016] 2. In this utility model, by setting up an inner shed and an outer shed, and forming an airtight heat-insulating cavity between the two, and then injecting hot air into the cavity by a heating blower, the problems of cracking caused by directly blowing hot air onto concrete segments in the prior art, as well as poor heat preservation performance and high energy consumption are solved.

In order to achieve the functions of heat preservation and protection, the inner canopy 201 is composed of glass fiber double-sided silicone coated cloth and aluminum silicate flame-retardant insulation cotton, and the outer canopy 202 is made of PE waterproof cloth.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, please refer to Figure 2 To enable rapid folding and assembly, the telescopic storage component 1 includes a longitudinal support rod 101, a transverse support rod 102, and a vertical upright rod 103.

[0032] Working principle: In use, firstly, the longitudinal support rod 101, transverse support rod 102, and vertical upright rod 103 of the telescopic storage component 1 are extended and connected through the three-way connector 105. The base 104 is fixed to the bottom of the vertical upright rod 103 and the side of the longitudinal support rod 101, forming a support frame. Then, the inner canopy 201 is installed on the outside of the telescopic storage component 1, and the outer canopy 202 is fixedly connected to the outside of the inner canopy 201, so that an airtight heat-insulating cavity 203 is formed between the inner canopy 201 and the outer canopy 202, which together constitute the heat insulation component 2. When heating is required, the heating blower 301 in the intelligent adjustment component 3 is activated, and its output end is adapted to the air inlet 204, and hot air is injected into the airtight heat-insulating cavity. Inside the body 203, hot air serves as an insulation medium, working in conjunction with the insulation material of the inner shed 201 to achieve heat preservation.

During operation, the temperature sensor 303 installed on the inner wall of the inner shed 201 monitors the temperature inside the shed in real time and feeds it back to the intelligent adjustment component 3 to control the operation of the heating blower 301. At the same time, the air pressure sensor 302 installed on the inner wall of the top of the outer shed 202 monitors the air pressure inside the cavity 203. When the air pressure is too high, the air pressure safety valve 206 set on the top of the outer shed 202 automatically releases the pressure. The hydrophobic device 205 installed on the surface of the outer shed 202, together with the outer shed 202 made of PE waterproof cloth, achieves waterproof and rainproof functions.
