Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, specifically relating to a simple curing device for prefabricated components. Background Technology

[0002] In the prefabricated building industry, steam curing is usually required to enhance the structural strength of precast concrete components. For large precast components installed on fixed molds, hoisting becomes difficult due to the fixed nature of the molds and the large size of the components. Therefore, these components are usually treated in situ on the fixed molds using steam curing equipment.

[0003] Currently, when steam curing precast components on fixed mold platforms, the components are usually covered with plastic film and then steam is introduced into them for steam curing. This method has poor heat preservation effect and requires waiting for the concrete to harden through natural evaporation, which is not only time-consuming but also reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a simple curing device for precast components, which can use insulation boards to achieve airtight insulation of the fixed mold table, thereby improving the insulation effect, effectively reducing the amount of steam used in the steam curing process, reducing the steam curing cost, and improving the curing effect.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A simple curing device for prefabricated components includes a square frame and a steam delivery pipe. The square frame is a rectangular structure formed by four right-angled vertical plates and multiple flat vertical plates that can be detachably connected. The top of the rectangular structure is provided with a cover plate to form a sealed insulation chamber.

[0007] Preferably, the detachable connection includes right-angled uprights placed at the four corners of a square frame, with a plurality of flat uprights arranged sequentially between two adjacent right-angled uprights. Each right-angled upright and flat upright has a locking groove on one side and a locking tenon that mates with the locking groove on the other side. Each right-angled upright and flat upright has a threaded groove on the top of one side, with a threaded rod threaded into the inner side of the threaded groove. Support plates are fixedly installed on the top and bottom of the inner side of each right-angled upright, and the bottom of the cover plate is attached to the top of the support plate.

[0008] Preferably, the cover plate has a threaded hole on one side, and the flat vertical plate has a round hole at the position corresponding to the threaded hole. The steam conveying pipe is threadedly connected to the cover plate through the round hole and the threaded hole, and the steam conveying pipe is equipped with a valve.

[0009] Preferably, the bottom of the cover plate is connected to an array of steam injection holes.

[0010] Preferably, one of the flat vertical plates is fixedly installed with multiple steam exhaust pipes, and one end of each steam exhaust pipe is threadedly connected to a pipe cap.

[0011] Preferably, a filter screen is fixedly installed on the inner wall of each of the steam discharge pipes.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a simple curing device for precast components. Through a detachable connection design, four right-angled uprights and multiple flat uprights are joined together using locking grooves and tenons to form a rectangular structure. A support plate supports a cover plate on top of the rectangular structure, and the cover plate is fixed to the top of the support plate by rotating a threaded rod, thus making the square frame a closed enclosure. Steam is then supplied to the interior of the square frame through a steam delivery pipe, increasing its internal temperature and humidity. This device utilizes insulation boards to achieve airtight insulation of the fixed mold platform, resulting in good insulation performance. This effectively reduces steam consumption during the steam curing process, lowers curing costs, and improves the curing effect. Attached Figure Description

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figure 1 - Figure 4 As shown, a simple curing device for prefabricated components includes a square frame 1 and a steam conveying pipe 11. The square frame 1 is a rectangular structure formed by four right-angled vertical plates 3 and multiple flat vertical plates 2 that can be detachably connected. The top of the rectangular structure is provided with a cover plate 9 to form a sealed insulation chamber.

[0022] The square frame 1 is designed for steam curing of precast components on a fixed mold platform. The design of the square frame 1 and the cover plate 9 ensures that a closed insulation chamber is formed on the outside of the precast component. The heat preservation design of the flat vertical plate 2 and the cover plate 9 has a good heat preservation effect, so that the staff can deliver steam into the square frame 1 through the steam delivery pipe 11 to increase the internal temperature and humidity, effectively reduce the amount of steam consumed during the steam curing process, and thus reduce the steam curing cost.

[0023] like Figure 1 and Figure 2 As shown, the detachable connection includes right-angled upright plates 3 placed at the four corners of the square frame 1. Several flat upright plates 2 are arranged sequentially between two adjacent right-angled upright plates 3. Each right-angled upright plate 3 and flat upright plate 2 has a locking groove 4 on one side and a locking tenon 5 that cooperates with the locking groove 4 on the other side. Each right-angled upright plate 3 has a threaded groove 6 on the top of one side and a threaded rod 7 is threadedly connected to the inside of the threaded groove 6. Support plates 8 are fixedly installed on the top and bottom of the inside of the right-angled upright plate 3. The bottom of the cover plate 9 is attached to the top of the support plate 8.

[0024] Specifically, the planar upright plate 2 and the right-angled upright plate 3 are detachably connected for upward or downward installation. The quick-connection between the locking groove 4 and the locking tenon 5 facilitates rapid disassembly of the device by the staff and allows for reuse. The connection between the locking groove 4 and the locking tenon 5 is not only stable but also has good sealing performance, ensuring that steam will not leak during the steam curing process, thereby maintaining the constantness of the steam curing environment. The top of the support plate 8 is covered with a cover plate 9 to increase the sealing effect of the square frame 1. The design between the threaded groove 6 and the threaded rod 7 is used to firmly lock the cover plate 9 to the top of the support plate 8, thereby ensuring the stability of the entire device during use. The material of the cover plate 9 must have good heat resistance and pressure resistance to adapt to the environment during the steam curing process.

[0025] like Figure 1 As shown, a threaded hole is provided on one side of the cover plate 9, and a round hole 10 is provided on the flat vertical plate 2 at the position corresponding to the threaded hole. The steam conveying pipe 11 is threadedly connected to the cover plate 9 through the round hole 10 and the threaded hole, and a valve 13 is provided on the steam conveying pipe 11.

[0026] The threaded hole design is used to realize the threaded connection between the cover plate 9 and the steam conveying pipe 11, which effectively maintains the sealing of the conveying pipe; while the design of the round hole 10 facilitates the quick connection between the two; the design of the valve 13 allows the staff to precisely control the steam flow during the steam curing process, thereby achieving fine adjustment of the curing environment temperature. By opening and closing the valve 13, the temperature change requirements during the steam curing process can be quickly responded to, ensuring that the components can be cured under the optimal temperature conditions.

[0027] like Figure 4 As shown, the bottom of the cover plate 9 is connected to an array of steam injection holes 12.

[0028] Specifically, the steam injection holes 12 are evenly distributed at the bottom of the cover plate 9, which helps to ensure that the steam is evenly distributed on the precast components, so as to ensure that the steam flow and distribution reach the optimal state, so as not to waste resources due to excessive flow, nor to affect the curing effect due to uneven distribution.

[0029] like Figure 3 As shown, multiple steam exhaust pipes 14 are fixedly installed on one of the flat vertical plates 2, and one end of the steam exhaust pipe 14 is threadedly connected to a pipe cap 15.

[0030] In the insulated chamber, excessive heating of steam may have an adverse effect on the precast components; the steam vent pipe 14 is designed to release the steam accumulated inside; the pipe cover 15 ensures that the inside remains sealed during non-venting periods; in addition, the threaded connection design allows workers to easily perform installation and disassembly operations as needed.

[0031] like Figure 3 As shown, a filter screen 16 is fixedly installed on the inner wall of each steam discharge pipe 14.

[0032] Specifically, the function of the filter screen 16 is to prevent any foreign objects from falling into the insulation chamber when the tube cover 15 is removed.

[0033] The working principle of this utility model is as follows: First, four right-angled upright plates 3 are fixed at the four corners of the outer perimeter of the component. Then, multiple flat upright plates 2 are inserted between every two right-angled upright plates 3 to form a rectangular frame. Then, the cover plate 9 is placed on the assembled rectangular frame. Then, the threaded rods 7 around the perimeter are screwed inward to the top of the cover plate 9. Finally, the steam conveying pipe 11 is connected to the cover plate 9 through the round hole 10 and the threaded hole. Steam is introduced into the interior of the cover plate 9 through the control valve 13. Then, the steam will be evenly sprayed into the insulation chamber from the steam injection hole 12 to effectively cure the component.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
