Description

Technical Field

[0001] The present invention relates to the technical field of precast concrete component curing, and more particularly, to an intelligent curing support frame for precast concrete components. Background Art

[0002] Under the background of the rapid development of prefabricated buildings, the factory production of precast concrete components has become an industry trend. After the precast concrete components are cast and formed, they need to be cured to ensure the performance of the concrete.

[0003] Traditional curing modes are divided into natural curing and steam curing. Natural curing refers to curing the concrete by means of a fixed curing rack in combination with manual spraying or automatic spraying. Steam curing refers to using a steam valve group in combination with a simple support frame to spray steam onto the surface of precast concrete components to accelerate the hydration reaction of cement, thereby accelerating the demoulding time of precast concrete components.

[0004] However, since the spray curing system and the steam curing system are independent of each other, when switching the curing mode (first spraying steam to accelerate the initial setting and then spraying water to control the temperature), it is necessary to disassemble the pipes corresponding to the current mode and replace them with the pipes required for the desired mode, which is time-consuming and laborious, the mode switching is less flexible, and the labor cost is increased. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent curing support frame for precast concrete components, which can flexibly switch between spray curing and steam curing, reduce labor costs, and improve the curing effect.

[0006] The present invention is achieved by the following technical solutions: An intelligent curing support frame for precast concrete components, comprising:

[0007] A support frame body, including a frame and a plurality of support plates arranged inside the frame. Adjacent two of the support plates cooperate to form a curing area, and precast concrete components are placed in the curing area;

[0008] A dual-medium spraying assembly for spraying steam or liquid water into the curing area to achieve steam curing or spray curing of precast concrete components, including a matrix flow channel opened in the support plate, a plurality of first spraying holes opened on the surface of the support plate, a dual-medium pipe communicated with the flow channel group, and a steam supply branch and a water supply branch for supplying steam or liquid water to the dual-medium pipe. A plurality of the first spraying holes are all communicated with the matrix flow channel.

[0009] Furthermore, the dual-medium spraying assembly further includes a plurality of grooves uniformly opened along the length direction of the support plate, and a plurality of the first spraying holes are uniformly distributed in the grooves.

[0010] Furthermore, the number of matrix flow channels on each of the support plates is two, and the two matrix flow channels are respectively located at the top and bottom of the support plate, and the top and bottom of the support plate are provided with first injection holes and grooves corresponding to the matrix flow channels.

[0011] Furthermore, a sealing strip is detachably connected in the groove, so as to realize opening or closing of the first injection hole through the sealing strip.

[0012] Furthermore, a plurality of bearing seats for bearing precast concrete components are arranged on the support plate, the plurality of bearing seats are evenly distributed between a plurality of grooves, and each of the bearing seats is located between two grooves.

[0013] Furthermore, the intelligent maintenance support frame also includes a plurality of transverse injection mechanisms arranged in the maintenance area, and the injection mechanisms are used to inject steam or liquid water into the maintenance area in a horizontal direction.

[0014] Furthermore, the lateral injection mechanism includes a first connecting rod and a second connecting rod whose ends are hinged to each other, and the first connecting rod and the second connecting rod are provided with built-in flow channels inside, and the built-in flow channels are respectively connected to the first injection holes on the support plates at the top and bottom of the curing area;

[0015] The ends of the first connecting rod and the second connecting rod that are away from each other are respectively hinged in grooves on the support plates at the top and bottom of the maintenance area, and the first connecting rod and the second connecting rod are both provided with second injection holes that are connected to the built-in flow channel.

[0016] Furthermore, the first connecting rod and the second connecting rod are both telescopic rods.

[0017] Furthermore, the steam supply branch and the water supply branch are connected to the inlet of the dual-medium pipeline through a three-way solenoid valve.

[0018] Furthermore, the frame includes a base, four vertical poles arranged on the base and a top cover arranged on the top of the poles. The poles are evenly provided with a plurality of mounting holes for fixing the support plate along their length direction. The mounting holes are used to cooperate with bolts to fix the support plate.

[0019] From the above, it can be seen that the present invention realizes flexible switching of steam or liquid water injection through a dual-media injection assembly, and cooperates with the flow channel group and the first injection hole on the support plate to achieve all-round coverage, thereby solving the problems of cumbersome switching of traditional maintenance modes and uneven maintenance effects, thereby achieving the effect of improving maintenance efficiency, reducing labor costs and improving the quality of concrete components.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Generally, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention.

[0027] Embodiment

[0028] The following refers to Figures 1-4 as shown, and is further described in combination with specific embodiments. This embodiment provides an intelligent curing support frame for precast concrete components, including a support frame body 10 and a dual-medium injection assembly 20 provided on the support frame body 10. Among them, the support frame body 10 includes a frame body 11 and a plurality of support plates 12 provided inside the frame body 11. Adjacent two support plates 12 cooperate to form a curing area 13, and precast concrete components are placed in the curing area 13.

[0029] The dual-medium injection assembly 20 is used to inject steam or liquid water into the curing area 13 to achieve steam curing or spray curing of precast concrete members. The dual-medium injection assembly 20 includes a matrix flow channel 21 formed in the support plate 12, a number of first injection holes 22 formed on the surface of the support plate 12, a dual-medium pipe 23 communicating with the flow channel group, and a steam supply branch 24 and a water supply branch 25 for supplying steam or liquid water to the dual-medium pipe 23. A number of first injection holes 22 are all communicated with the matrix flow channel 21.

[0030] It should be noted that in this embodiment, the steam supply branch 24 and the water supply branch 25 are respectively connected to a steam generating device (not shown in the figure) and a liquid water supply device (not shown in the figure). The steam generating device and the liquid water supply device are well-known technical means in the art and are not the improvement points of the present invention, so no more details will be given.

[0031] When performing steam curing, the steam supply branch 24 transports steam to the matrix flow channel 21 through the dual-medium pipe 23. The steam is sprayed from the first injection holes 22 to the curing area 13 through the matrix flow channel 21, realizing steam curing of the precast concrete members in the curing area 13. When performing spray curing, the water supply branch 25 switches to transport liquid water, and the water flow forms an atomized water curtain from the first injection holes 22 along the same path, realizing spray curing of the precast concrete members in the curing area 13. The curing mode switching is relatively flexible, reducing the labor cost. Moreover, the steam curing and spray curing are used in combination, which can effectively shorten the curing time of the precast concrete members and improve the forming quality of the precast concrete members at the same time.

[0032] Furthermore, the dual-medium injection assembly 20 further includes a plurality of grooves 26 uniformly formed along the length direction of the support plate 12. The grooves 26 are arranged along the width direction of the support plate 12, and a number of first injection holes 22 are uniformly distributed in the grooves 26.

[0033] The grooves 26 are arranged on the surface of the support plate 12, and the first injection holes 22 are arranged in the grooves 26. After the steam or liquid water is transported into the matrix flow channel 21, the first injection holes 22 spray the medium upward from the bottom of the grooves 26 to the curing area 13.

[0034] Furthermore, the number of matrix flow channels 21 on each support plate 12 is two. The two matrix flow channels 21 are respectively located at the top and bottom of the support plate 12, and the top and bottom of the support plate 12 are both provided with first injection holes 22 and grooves 26 corresponding to the flow channel group.

[0035] It can be understood that by setting the matrix channels 21 to two, and simultaneously providing first injection holes 22 and grooves 26 corresponding to the matrix channels 21 at the top and bottom of the support plate 12, steam or liquid water can be injected into the curing area 13 through the first injection holes 22 in the up and down directions, avoiding the uneven coverage caused by a single injection direction, and thus improving the curing effect.

[0036] Furthermore, a sealing insert 27 is detachably connected in the groove 26 to open or close the first injection hole 22 through the sealing insert 27.

[0037] Through the cooperation of the groove 26 and the sealing insert 27, the opening or sealing of the first injection hole 22 in the groove 26 is achieved. When steam curing is required, the sealing insert 27 in the corresponding groove 26 is removed to expose the first injection hole 22 and inject the medium into the curing area 13; when some injection holes need to be closed, only the sealing insert 27 needs to be installed in the corresponding groove 26 to cover the target hole position, so that the corresponding groove 26 can be flexibly selected according to the size of the precast concrete member to inject steam or liquid water onto the surface of the precast concrete member, avoiding waste of resources.

[0038] Furthermore, a plurality of bearing seats 14 for bearing precast concrete members are provided on the support plate 12. The plurality of bearing seats 14 are evenly distributed between multiple grooves 26, and each bearing seat 14 is located between two grooves 26.

[0039] The bearing seat 14 is configured to form a physical isolation between two adjacent grooves 26, so that the bottom surface of the precast concrete member is kept at a gap from the area where the groove 26 is located, avoiding the situation that the precast concrete member is in contact with the bottom surface of the support plate 12 and it is difficult to inject the medium to the bottom of the precast concrete member. When steam or liquid water is ejected outward through the first injection hole 22 in the groove 26, the bearing seat 14 stably supports the precast concrete member at a predetermined height, thus ensuring the curing effect on the precast concrete member.

[0040] Furthermore, the intelligent curing support frame proposed in this application further includes a plurality of horizontal injection mechanisms 30 provided in the curing area 13. The injection mechanism is used to inject steam or liquid water into the curing area 13 in the horizontal direction.

[0041] Specifically, the lateral injection mechanism 30 includes a first connecting rod 31 and a second connecting rod 32 whose ends are hinged to each other. Built-in flow channels 33 are provided inside both the first connecting rod 31 and the second connecting rod 32. The built-in flow channels 33 are respectively communicated with the first injection holes 22 on the support plates 12 at the top and bottom of the curing area 13. One end of the first connecting rod 31 and the second connecting rod 32 away from each other is respectively hinged in the grooves 26 on the support plates 12 at the top and bottom of the curing area 13, and second injection holes 34 communicated with the built-in flow channels 33 are provided on both the first connecting rod 31 and the second connecting rod 32.

[0042] When the precast concrete member is placed in the curing area 13, by adjusting the hinge angle, different included angles are formed between the two connecting rods, so as to change the coverage range of the second injection holes 34. After steam or liquid water enters the built-in flow channels 33 from the first injection holes 22 of the support plates 12, it is vertically divided into two connecting rods and finally diffuses horizontally through the second injection holes 34. In the steam curing stage, the steam is laterally injected from the second injection holes 34 to the side of the member; in the spray curing stage, the liquid water completes the coverage through the same flow channel and the second injection holes 34 without disassembling or replacing the pipeline.

[0043] It should be noted that in this embodiment, the built-in flow channels 33 of the first connecting rod 31 and the second connecting rod 32 are communicated with the first injection holes 22 through a hose 35. By means of the hose 35, when adjusting the hinge angle of the first connecting rod 31 and the second connecting rod 32, the built-in flow channels 33 of the first connecting rod 31 and the second connecting rod 32 can be stably communicated with the first injection holes 22. And one end of the first connecting rod 31 and the second connecting rod 32 away from each other is detachably connected in the grooves 26 on the support plates 12 at the top and bottom of the curing area 13. Specifically, hinge seats 36 can be provided at one end of the first connecting rod 31 and the second connecting rod 32 away from each other. The first connecting rod 31 and the second connecting rod 32 are hinged to the hinge seats 36, and the hinge seats 36 are detachably connected to the corresponding grooves 26 by bolts.

[0044] Furthermore, both the first connecting rod 31 and the second connecting rod 32 are telescopic rods. By setting the first connecting rod 31 and the second connecting rod 32 as telescopic rods, the first connecting rod 31 and the second connecting rod 32 can be correspondingly extended or contracted, so that it is more convenient to adjust the hinge angle of the first connecting rod 31 and the second connecting rod 32, and it can adapt to precast concrete members of different heights.

[0045] Furthermore, the steam supply branch 24 pipeline and the water supply branch 25 pipeline are communicated with the inlet of the dual-medium pipeline 23 through a three-way solenoid valve 28.

[0046] When the maintenance mode needs to be switched, the three-way solenoid valve 28 receives an external control signal to switch the conduction state. For example, in the steam maintenance mode, the three-way solenoid valve 28 connects the steam supply branch 24 with the dual-medium pipeline 23, and closes the water supply branch 25; in the spray maintenance mode, the water supply branch 25 is switched to conduction. This structure does not require manual disassembly or installation of pipelines, and can achieve alternating delivery of two media only by valve switching.

[0047] In some specific embodiments, the three-way solenoid valve 28 can be connected to the pipeline by flange connection, and its control signal can be received by wire or wireless. For example, the solenoid valve can be integrated with an Internet of Things module to achieve remote mode switching control; or it can be linked with a temperature sensor to automatically switch to the spray mode when it detects that the temperature of the maintenance area 13 exceeds a threshold.

[0048] Furthermore, the frame 11 includes a base 111, four vertical poles 112 arranged on the base 111, and a top cover 113 arranged on the top of the vertical poles 112. The vertical poles 112 are evenly provided with a plurality of mounting holes 1121 for fixing the support plate 12 along the length direction thereof. The mounting holes 1121 are used to cooperate with bolts to fix the support plate 12.

[0049] By providing a plurality of mounting holes 1121 on the vertical pole 112, the balancing plate can be flexibly installed at a height according to the size of the precast concrete component, thereby improving the versatility of the maintenance process. In addition, the matching mode of the mounting holes 1121 and the bolts simplifies the disassembly and assembly process of the support plate 12 and shortens the manual adjustment time.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
