Description

Technical Field

[0001] This utility model relates to the field of steam curing devices, and in particular to a mobile T-beam steam curing device for cold regions. Background Technology

[0002] Many highway and municipal public works projects involve T-beam construction. In cold regions, the concrete construction of T-beams is affected by environmental factors such as temperature, humidity, and air quality, which can impact the concrete strength and appearance. For example, in cold regions, low temperatures, large temperature differences, and dry environments can cause micro-cracks to appear on the concrete surface. Dust, gravel, and other impurities in the air can also adhere to the concrete surface, affecting its appearance. Therefore, conventional curing methods are insufficient to guarantee construction quality for T-beams, impacting project progress and relatively increasing construction costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a mobile T-beam steam curing device for cold regions, which effectively solves the problems of slow early strength growth of T-beam concrete in cold regions and susceptibility to surface cracks caused by temperature differences. It ensures the quality of T-beam concrete pouring and the overall construction progress of the project. This invention is reliable, easy to operate, quality guaranteed, and creates good economic benefits.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A mobile T-beam steam curing device for cold regions includes a portal frame assembled from longitudinal beams, transverse beams, columns and diagonal braces. An insulation layer is laid outside the portal frame to form an insulation chamber. A steam spray pipe is installed inside the insulation chamber. The input end of the steam spray pipe is connected to the steam curing spray control cabinet, and the output end of the steam spray pipe is connected to the steam nozzle. The steam nozzle is evenly distributed in multiple groups on the steam spray pipe.

[0006] The longitudinal beams, transverse beams, columns, and diagonal braces are fixed together by angle brackets and self-drilling screws.

[0025] like Figure 1-2 As shown, a mobile T-beam steam curing device for cold regions includes a portal frame with an insulation layer 1 installed outside the frame to form a curing chamber. An insulated door 12 is installed at one end of the curing chamber, and two insulated doors 12 are hinged to the curing chamber to open or close. A steam spray pipe 6 (made of galvanized steel pipe) is fixed inside the curing chamber by U-shaped fasteners 14. The input end of the steam spray pipe 6 is connected to a steam curing spray control cabinet 11 outside the curing chamber. Multiple steam nozzles 7 are arranged on the steam spray pipe 6. The steam curing spray control cabinet 11 transmits steam and its heat to various parts of the curing chamber. The steam is sprayed onto the T-beam through the steam nozzles 7, ensuring sufficient curing humidity and temperature for the T-beam.

[0026] The portal frame consists of longitudinal beams 2, transverse beams 3, columns 4, and diagonal braces 5, connected by angle brackets and self-drilling screws. All components—longitudinal beams 2, transverse beams 3, columns 4, and diagonal braces 5—are made of 100mm × 60mm × 2mm square tubing. During installation, precise measuring tools and marking pens are used to accurately mark the joint positions of each component on the longitudinal beams 2 and transverse beams 3. This includes determining the intersection points of the longitudinal beams 2 and transverse beams 3, as well as their relative positions within the portal frame. The clarity and accuracy of the markings are ensured for rapid identification during subsequent assembly.

[0027] The angle and required length of the diagonal brace 5 at the splice point need to be measured. An angle measuring tool and a tape measure should be used to accurately measure and mark the diagonal brace to ensure it can be correctly installed on the frame, providing the necessary support and stability.

[0028] Mark the connection points of the column 4 with the diagonal brace 5, the crossbeam 3, and the longitudinal beam 2 using a marker. This includes determining the intersection of the column 4 and the diagonal brace 5, as well as the connection points of the column 4 with the crossbeam 3 and the longitudinal beam 2. Ensure the accuracy and consistency of the markings so that the components can be accurately aligned and secured during assembly.

[0029] The column 4 and the caster 10 (heavy-duty swivel caster with brake) are connected by welding and self-drilling screws. During installation, the corresponding hole positions are marked in advance at the center of the bottom of the column 4 according to the screw hole positions of the caster 10. The connection between the column 4 and the caster 10 is sealed by welding, and screws are driven into the corresponding holes for reinforcement.

[0030] When processing insulation layer 1, use a hot wire cutter or utility knife to cut the rock wool board / sun panel to the size that fits the portal frame, and fix it to the portal frame with rivets to achieve insulation.

[0031] The steam nozzles 7 are evenly distributed and fixed on the steam spray pipes 6, ensuring that steam can be evenly sprayed to all areas inside the shed. The distance between the steam nozzles 7 should be appropriately adjusted according to the size of the shed and the steam flow rate. A pressure control valve, a CU50 temperature sensor, and an HS15P humidity sensor are installed on the steam spray pipes 6. The pressure control valve plays a crucial role in the hydraulic system; it adjusts the fluid pressure according to industrial production needs, achieving pressure stabilization and depressurization, protecting the system from overpressure damage, and controlling the action sequence of actuators through a sequence valve to ensure efficient and safe system operation. The temperature sensor can detect ambient temperature and output signals in various ways to display the temperature on-site. It can also transmit data to a data acquisition unit for storage, analysis, and chart output. Furthermore, it can control heating or cooling equipment to maintain stable ambient temperature, making it a key device for monitoring temperature and related parameters in environmental monitoring. The humidity sensor uses a hygroscopic element to measure ambient humidity and converts it into electrical or digital signals. It has data recording and transmission functions and is widely used in agriculture, industry, meteorology, environmental protection, and other fields to monitor and control ambient humidity, ensuring appropriate parameters.

[0032] The door hinge of the insulated door 12 should be welded to the column 4 smoothly and without gaps. Sealing strips should be installed on the top, sides, and bottom of the insulated door 12 to ensure a tight seal between the insulated door 12 and the column 4.

[0033] Windbreak curtains 9 are installed around the bottom of the curing chamber to cover the bottom of the curing chamber and ensure that a closed space can be formed when the curing shed is working. Hooks are then installed above the lowest steam exhaust pipes 6 around the chamber and on the insulation door 12 to ensure that the windbreak curtains 9 can be flipped up and hung on the hooks when the steam curing shed is not working, thus achieving the mobility and convenience of the device.

[0034] Working principle and process:

[0035] Step 1: Assemble the longitudinal beam 2 and the transverse beam 3 according to the marked splicing positions, and secure them using angle brackets and self-drilling screws. Ensure the connection is firm and stable.

[0036] Step 2: Install the uprights 4 at the designated positions on the longitudinal beams 2 and the transverse beams 3, and connect them to the transverse beams 2 and the longitudinal beams 3 using angle brackets and self-drilling screws.

[0037] Step 3: Install the diagonal brace 5 onto the frame at the determined angle and length, and secure it with angle brackets and self-drilling screws; ensure that the diagonal brace can provide the necessary support and maintain the stability of the frame.

[0038] Step 4: After assembly, inspect the entire portal frame to ensure that all components are correctly installed and securely connected; if any problems or deviations are found, adjust and correct them in a timely manner to ensure the accuracy and stability of the frame.

[0039] Step 5: Use a hot wire cutter or utility knife to cut the rock wool board / polycarbonate sheet to the size required for the frame. Then, secure the rock wool board / polycarbonate sheet to the portal frame with rivets, ensuring flatness and stability.

[0040] Step 6: Fill and smooth the gaps caused by uneven cutting with rock wool strips. At the edges of the rock wool strips, you can apply additional adhesive or use sealant strips to enhance the seal.

[0041] Step 7: Select galvanized steel pipes with appropriate inner diameter and good corrosion resistance to ensure smooth steam transmission within the pipes. Design the layout of the galvanized steel pipes according to the size and shape of the curing shed. The pipes should be distributed as evenly as possible to ensure that steam can evenly cover all corners of the shed.

[0042] Step 8: Galvanized steel pipes are connected using sleeves to ensure a tight seal and stability at the joints. U-shaped fasteners are also installed at pipe bends and branches to enhance pipe support. Pressure control valves are installed on the galvanized steel pipes to ensure steam pressure fluctuates within a reasonable range, preventing excessively high or low pressure from adversely affecting the curing effect. Intelligent control equipment, such as temperature and humidity sensors, is installed inside the steam curing shed to monitor and adjust the temperature and humidity in real time, ensuring the safety and effectiveness of the curing process.
