Description

Technical Field

[0001] This utility model relates to a steam curing device for prefabricated building concrete components. Background Technology

[0002] With the rapid development of industrialized construction, prefabricated buildings have been widely used in construction projects due to their advantages such as high construction efficiency, easy quality control, and environmental friendliness. The core of prefabricated buildings is precast concrete components, and the strength and durability of these components largely depend on the curing process. Steam curing, as an efficient curing method, can accelerate the hydration reaction of concrete, shorten the curing cycle, and improve component performance by controlling temperature and humidity.

[0003] Currently, steam curing devices for prefabricated concrete components on the market have several shortcomings. First, during the loading and unloading of prefabricated components, due to unreasonable device structural design and limited forklift operating space, collisions between the forklift boom and device components are prone to occur, affecting loading and unloading efficiency and potentially damaging the components or the device itself. Second, the structures used to support prefabricated components in existing devices are often quite simple, leading to swaying or uneven stress on the components during curing, potentially causing deformation or surface damage. Third, the uniformity of steam curing is poor; some devices only have steam jet structures above or below the components, resulting in uneven heating and moisturizing of different parts of the components, affecting curing quality. Furthermore, the stability of the movable frame during lifting is insufficient, easily tilting or jamming, affecting operational safety and potentially causing secondary damage to the components. Utility Model Content

[0004] The purpose of this invention is to solve the problems of inconvenient loading and unloading, poor support stability, insufficient curing uniformity, and poor lifting stability of the movable frame in the existing technology, and to provide a prefabricated building concrete component steam curing device with reasonable structure, convenient operation, and good curing effect.

[0005] A steam curing device for prefabricated building concrete components includes a base plate, vertical beams, horizontal beams, an upper frame, and a movable frame;

[0006] The upper surface of the base plate is connected to the cross beam via vertical beams, and the upper frame is mounted above the cross beams; the movable frame is located between the base plate and the cross beams, and a lifting mechanism is provided between the movable frame and the base plate, the lifting mechanism being used to drive the movable frame to rise and fall vertically.

[0007] The top of the movable frame is provided with several support columns and several atomizing ports, and the bottom of the upper frame is provided with several upper spray ports; the middle of the movable frame is provided with a through groove, the size of which is larger than the size of the crossbeam, so that the crossbeam can pass through the through groove when the movable frame is raised or lowered.

[0008] Furthermore, the movable frame is equipped with retractable guide posts around its perimeter. These guide posts are retractable structures, including a fixed section and a telescopic section. One end of the fixed section is fixedly connected to the base plate, and one end of the telescopic section is fixedly connected to the lower surface of the movable frame. The end of the telescopic section furthest from the movable frame is fitted inside the fixed section and slides within it. The retractable guide posts provide precise guidance for the lifting and lowering movement of the movable frame. The rigid connection between the fixed section and the base plate ensures the stability of the guiding reference. The fixed connection between the telescopic section and the movable frame, as well as its sliding engagement with the fixed section, allows the telescopic section to extend and retract synchronously with the lifting and lowering of the movable frame, maintaining constant constraint on it.

[0009] Furthermore, the lifting mechanism is a hydraulic cylinder, with the cylinder body fixedly connected to the base plate and the end of the hydraulic cylinder's push rod away from the cylinder body fixedly connected to the lower surface of the movable frame. The hydraulic cylinder has high precision in its extension and retraction stroke, enabling precise control of the movable frame's lifting height. This ensures uniform force distribution on the precast components during lifting or placement, reducing the risk of component deformation due to impact or displacement errors, and significantly improving the reliability of the device operation and the protection of the components.

[0010] Furthermore, the top of the support column is an arc-shaped structure. Compared to sharp or flat structures, the arc-shaped structure avoids localized point contact or hard-edge compression between the support column and the component. This prevents damage such as indentations and cracks from appearing on the component surface, protecting the component's appearance integrity and structural strength.

[0011] Furthermore, there are three crossbeams, which are spaced apart along the length of the base plate, and no crossbeams are installed at the inlet and outlet of the prefabricated component. This greatly simplifies the forklift operation process, allowing the forklift to directly reach into the device from the inlet and outlet to quickly place or remove components, significantly improving loading and unloading efficiency.

[0012] Furthermore, the system also includes a water pump and water pipes. Both the atomizing port and the upper spray nozzle are connected to the water pump's outlet via water pipes, which are equipped with valves. The stable water supply from the pump ensures that the atomizing port and upper spray nozzle continuously generate uniform steam or water mist, meeting the continuous humidity and temperature requirements during the curing of precast components. The valves allow for precise control of the curing intensity, enabling adjustments to the steam injection volume based on the material, size, and curing stage of different precast components. This ensures effective curing while avoiding water waste, thus improving the energy efficiency and applicability of the device.

[0013] Furthermore, the through groove is characterized in that its width is 50-100mm greater than the width of the crossbeam, and its length is 50-100mm greater than the length of the crossbeam. This ensures that the crossbeam can pass smoothly through the through groove without structural interference.

[0014] Furthermore, the upper frame is fixedly connected to one end of the base plate via a connecting rod. The function of the connecting rod is to stably fix the upper frame at a preset height, ensuring that the relative position between the upper frame, the base plate, and the movable frame remains constant.

[0015] Beneficial effects:

[0016] By optimizing the structural design, the ease of operation and structural stability have been significantly improved. The support columns at the top of the movable frame adopt an arc structure, which can not only stably support the precast components but also reduce damage to the lower surface of the components. The atomizing nozzles on the movable frame and the upper spray nozzles at the bottom of the upper frame are connected to a water pump through water pipes, which can simultaneously spray steam from the upper and lower surfaces of the precast components, ensuring uniform heating and humidification of all parts of the components, greatly improving the quality and efficiency of curing. The overall structural design is reasonable and can effectively meet the steam curing requirements of prefabricated building concrete components. Attached Figure Description

[0023] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0024] Example 1:

[0025] like Figure 1-5As shown, a steam curing device for prefabricated building concrete components includes a base plate 3, vertical beams 6, horizontal beams 7, an upper frame 2, and a movable frame 8. The base plate 3 is made of 10mm thick steel plate, providing a stable support foundation for the entire device. The vertical beams 6 are six square steel pipes, which are fixed to the four corners of the base plate 3 by welding. The horizontal beams 7 are I-beams, connected to one end of the vertical beams 6 by welding, and are arranged parallel to the base plate 3.

[0026] The upper frame 2 is a frame structure welded from angle steel, and is fixedly connected to one end of the base plate 3 via connecting rods. The movable frame 8 is made of 8mm thick steel plate and is located between the base plate 3 and the crossbeam 7, parallel to both. A hydraulic cylinder 5 is installed between the movable frame 8 and the base plate 3. The cylinder body of the hydraulic cylinder 5 is fixed to the center of the base plate 3 with bolts, and the top of the push rod of the hydraulic cylinder is fixedly connected to the center of the lower surface of the movable frame 8 with bolts. The maximum stroke of the hydraulic cylinder is 1000mm, which can drive the movable frame 8 to rise and fall stably in the vertical direction.

[0027] Four guide columns 4 are provided around the movable frame 8, located at the four corners of the movable frame 8 respectively; the guide columns 4 are telescopic structures, with one end fixedly connected to the base plate 3 by welding, and the other end fixedly connected to the lower surface of the movable frame 8 by welding.

[0028] The top of the movable frame 8 is provided with several support columns 82 and several atomizing ports 81. The support columns 82 are round steel with a diameter of 30mm and a height of 50mm. The top of the column is an arc structure with a radius of 8mm. The arc structure can achieve point contact with the lower surface of the precast component 1, thereby preserving the curable area of ​​the precast component 1 to the greatest extent.

[0029] The support columns 82 are spaced apart along the length and width of the movable frame 8. The atomizing nozzle 81 is a high-pressure atomizing nozzle, located in the gap between two adjacent support columns 82, and the atomizing nozzle 81 is fixed to the movable frame 8 by a threaded connection.

[0030] The bottom of the upper frame 2 is provided with several upper spray nozzles 21, which are fixed to the upper frame 2 by threaded connection.

[0031] There are three crossbeams 7, which are distributed at intervals along the length of the base plate 3. Crossbeams 7 are not set at the entrance and exit of the precast component 1 (i.e. at both ends of the length of the base plate 3) to facilitate forklift operation.

[0032] The device also includes a water pump (not shown in the figure) and a water pipe (not shown in the figure). The water pipe (not shown in the figure) is a high-pressure rubber hose. The atomizing port 81 and the upper spray port 21 are both connected to the outlet of the water pump through the water pipe. The water pipe is equipped with a valve to control the flow of water and regulate the flow rate.

[0033] The working process of this embodiment is as follows:

[0034] S1. Loading and unloading prefabricated component 1: Use a forklift to lift the prefabricated component 1. Since there is no crossbeam 7 at the inlet and outlet of the prefabricated component 1, the forklift arm can be smoothly extended into the device to place the prefabricated component 1 on the upper surface of the crossbeam 7. After the placement is stable, start the hydraulic cylinder. The push rod of the hydraulic cylinder extends and drives the movable frame 8 to move upward. Under the guidance of the guide column 4, the movable frame 8 maintains a steady rise.

[0035] S2. Lifting the precast component 1: During the upward movement of the movable frame 8, the support column 82 on it gradually contacts the lower surface of the precast component 1. As the hydraulic cylinder continues to lift, the support column 82 lifts the precast component 1 upward until the lower surface of the precast component 1 leaves the upper surface of the crossbeam 7. At this time, the precast component 1 is completely supported by the support column 82.

[0036] S3. Steam curing: Start the water pump and open the valve. High-pressure water is delivered to the atomizing port 81 and the upper spray port 21 through the water pipe. After atomization, steam is formed and sprayed onto the upper and lower surfaces of the precast component 1 for curing. Since the atomizing port 81 and the upper spray port 21 are evenly distributed, it can ensure that all parts of the precast component 1 are heated and moistened evenly.

[0037] S4. After maintenance: turn off the water pump and valve, control the hydraulic cylinder push rod to retract, and the movable frame 8 will drive the precast component 1 to move downward until the lower surface of the precast component 1 is placed back on the crossbeam 7 and the support column 82 is separated from the precast component 1; continue to control the movable frame 8 to descend to the initial position, and finally use a forklift to remove the precast component 1 from the crossbeam 7.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
