Description

Technical Field

[0001] This utility model relates to a steam curing hood device, specifically a convenient steam curing hood device for precast beams and slabs, belonging to the field of building construction technology. Background Technology

[0002] Precast beams and slabs are concrete beam and slab components that are prefabricated in a factory or on the construction site. After the concrete is poured and formed, they require steam curing equipment to accelerate strength development and shorten the curing cycle. The precast beam and slab steam curing equipment uses a steam generator to produce high-temperature steam, and with a sealing structure to prevent steam leakage, it creates a constant temperature and humidity environment in the curing space, thereby ensuring the curing quality and efficiency of the precast beams and slabs and improving their structural performance.

[0003] A search revealed that Chinese utility model patent CN220297437U discloses a post-construction curing device for precast building slabs. The device includes a base plate with side plates on both sides of its central portion. A top plate is formed on top of the two sets of side plates, and the top plate and the two sets of side plates together constitute a fixed curing hood. The fixed curing hood has open, movable sealing doors on both its front and rear open sides. A steam generator is installed on the top plate to supply curing steam into the fixed curing hood. Multiple sets of rotating rollers are arranged from front to back on the base plate to transport the precast slabs to the fixed curing hood for curing. After curing, the slabs are conveyed out from the other end of the fixed curing hood. An opening and closing control mechanism is provided on the fixed curing hood, which is connected to the open, movable sealing doors at the front and rear ends of the fixed curing hood to control their lifting and opening / closing. The device improves continuous curing efficiency by using multiple sets of rotating rollers to transport the precast slabs to the fixed curing hood for curing and then conveying them out from the other end of the fixed curing hood after curing.

[0004] In the process of using the above-mentioned precast slab post-curing device, the precast beam steam curing hood is usually of a fixed height. However, due to differences in design load-bearing requirements and application scenarios, the height of precast beams often varies. The fixed-height precast beam steam curing hood cannot be adapted to precast beams of different specifications, resulting in some beams not being fully included in the curing space. This leads to uneven steam curing, affecting the strength growth and structural performance of the precast beams, and reducing curing quality and construction efficiency.

[0005] In existing technologies, there are still problems such as inconvenience in relocating equipment to the construction site and low positioning efficiency; at the same time, steam cannot be evenly distributed in the curing space, and the temperature and humidity gradient cannot be effectively eliminated, so as to ensure that all parts of the precast beams and slabs are cured evenly.

[0006] Therefore, the key to solving the above-mentioned technical problems lies in developing a simple, stable, and reliable steam curing hood for precast beams and slabs. Summary of the Invention

[0007] In view of the many defects and shortcomings of the above-mentioned background technology, this utility model has made improvements and innovations, aiming to provide a simple, safe and reliable convenient steam curing hood for precast beams and slabs. The height of the curing hood can be adjusted to suit precast beams and slabs of different heights, thereby significantly improving curing quality and construction efficiency, and reducing the quality risks caused by uneven curing.

[0008] Another objective of this invention is that the built-in steam circulation component enables the steam to form an efficient circulation flow inside the equipment, ensuring that the steam is evenly distributed in the curing space, effectively eliminating temperature and humidity gradients, thereby ensuring that all parts of the precast beams and slabs receive balanced curing.

[0009] One objective of this invention is to provide a translation component below the device. By utilizing the precise cooperation between the guide rail and the slider seat, the device can move smoothly along the track, significantly improving the ease of relocation and positioning efficiency of the device at the construction site.

[0010] To solve the above problems and achieve the above-mentioned invention objectives, this utility model provides a convenient steam curing hood for precast beams and slabs, achieved through the following design structure and technical solutions:

[0011] A portable steam curing hood for precast beams and slabs includes a steam generator and further includes:

[0012] The support frame is arranged opposite to each other. Each support frame has two legs with sliding grooves and a sliding opening through the upper crossbeam of the support frame.

[0013] Side guard plates are connected between the two legs on both sides of the two support frames.

[0014] The sliders are slidably connected to four grooves.

[0015] The protective cover has its upper two ends movably inserted into the corresponding sliding ports, and its two side plates are movably inserted into the interior of the two side protective plates, with the ends of the two side plates connected to the corresponding sliders.

[0016] An adjustment mechanism is connected between the two support frames above, used to drive the protective cover to move up and down;

[0017] A sealing structure, with the sealing structures connected to the outside of each support frame;

[0018] The steam generator is located outside one of the protective plates.

[0019] Preferably, the adjustment mechanism includes:

[0020] A fixing frame, wherein the fixing frame is symmetrically connected to the upper inner side of two support frames, and a fixing hole is penetratingly formed in the middle of the fixing frame;

[0021] A screw rod, wherein two ends of the screw rod are rotatably connected in the fixing holes of the fixing frame;

[0022] A driving motor, wherein the driving motor is fixed on one of the fixing frames through a mounting bracket, and the working end of the driving motor is connected to the screw rod at the end;

[0023] Two thread blocks, wherein the two thread blocks are respectively in threaded connection with two ends of the screw rod;

[0024] Two connecting seats, wherein the upper end of each of the two connecting seats is connected to the lower end of the corresponding thread block, and the lower end of each connecting seat is connected to the top end face of a protective cover.

[0025] Preferably, the screw rod is a bidirectional screw rod, and both ends of the screw rod are connected to the fixing holes of the fixing frame through bearings.

[0026] Preferably, the connecting seat comprises: a diagonal bracing frame; a first connecting seat, wherein the upper end of the first connecting seat is fixedly connected to the thread block, and the lower end of the first connecting seat is movably connected to the upper end of the diagonal bracing frame; a second connecting seat, wherein the upper end of the second connecting seat is movably connected to the lower end of the diagonal bracing frame, and the lower end of the second connecting seat is fixedly connected to the top end face of the protective cover;

[0027] Wherein, the two diagonal bracing frames of the two connecting seats are arranged in a splayed shape.

[0028] In the present utility model, the bidirectional screw rod is driven to rotate by the driving motor, and based on the thread transmission principle, the two thread blocks are driven to move in opposite directions, thereby changing the included angle of the two connecting seats. The change of the angle of the diagonal bracing frames prompts the protective cover to lift in the vertical direction, realizing flexible adjustment of the height of the steam curing equipment, so that the steam curing equipment can adapt to prefabricated beam slabs of different heights, ensuring that all kinds of prefabricated beam slabs can obtain comprehensive and effective steam curing.

[0029] Preferably, the support frame as a whole is in a U-shaped structure; an accommodating compartment is opened inside the side protection plate.

[0030] In the present utility model, the cross section of the side protection plate is in a U-shaped.

[0031] Preferably, the protective cover comprises: a protective cover body, wherein the protective cover body as a whole is in a U-shaped structure; sealing plates, wherein the sealing plates are symmetrically and vertically connected to the ends of the two ends of the top of the protective cover body, and the sealing plates are movably inserted into sliding ports at corresponding ends.

[0032] Preferably, the sealing structure is a rolling shutter door assembly, and the rolling shutter door assemblies are respectively installed on the outer sides of each support frame for sealing the openings of each support frame.

[0033] In this invention, the roller shutter door assembly provides a convenient access channel and reliable sealing protection for the steam curing equipment. It can be quickly opened when the precast beams and slabs are moved in and out, and after closing, it can effectively prevent steam leakage in conjunction with the sealing structure. Meanwhile, the steam generator can continuously and stably generate high-temperature steam to provide sufficient heat source for the curing of precast beams and slabs. The steam is then transported to the curing space through pipelines to maintain a suitable curing temperature and humidity environment.

[0034] Preferably, an electrical control cabinet is also provided outside the protective plate on the same side of the steam generator, and the electrical control cabinet is electrically connected to the drive motor of the steam generator and the regulating mechanism.

[0035] Preferably, it also includes a steam circulation assembly disposed inside the protective cover, the steam circulation assembly comprising:

[0036] The partition is connected to the upper part of the protective cover, and ventilation holes are opened through the four corners of the partition.

[0037] The first circulating fan is installed in two ventilation holes on the same side or different sides respectively;

[0038] The second circulating fan is installed in two other ventilation holes.

[0039] In this invention, an electrical control cabinet is fixedly installed on one side of the outer wall of one of the two protective plates, and both the first and second circulating fans are electrically connected to the electrical control cabinet. A partition is fixedly connected to the inner wall of the protective cover. The electrical control cabinet can intelligently control and manage the maintenance equipment, realizing the start-stop regulation, parameter setting, and operation status monitoring of equipment such as the steam generator, drive motor, first and second circulating fans, etc. The partition can divide the interior of the maintenance equipment into two spaces, constructing independent steam circulation channels, which facilitates the optimization of steam pipeline layout and airflow organization.

[0040] Two sets of ventilation holes provide a flow channel for steam circulation; two first circulation fans use negative pressure to directionally draw steam from the bottom of the curing equipment to the top space; two second circulation fans draw steam from the top back to the bottom, ensuring efficient circulation of steam in the curing space, thereby ensuring the uniformity of temperature and humidity in the curing space and avoiding local temperature differences or uneven steam concentration.

[0041] Preferably, it also includes a translation component, which includes:

[0042] Movable seats are attached to the bottom of the two side protective plates respectively;

[0043] The guide rails are movably inserted into two movable seats.

[0044] In this utility model, the bottom of both side protective plates is fixedly connected to movable seats, and the inner surface of both movable seats is movably inserted with guide rails. Through the sliding cooperation between the guide rails and the movable seats, the protective cover can achieve stable and flexible displacement along the guide rails, effectively reducing the moving resistance and operation difficulty of the equipment on the construction site, and enhancing the convenience of using the equipment.

[0045] Working principle: When in use, the operator first adjusts the height of the protective cover (4) according to the height of the precast beam (10) to adapt to the precast beam (10) of different specifications; when adjusting the height of the protective cover (4), the operator first starts the drive motor (53), and its output end drives the screw (52) to rotate. Because the threads on both sides of the screw (52) are opposite and threadedly connected to the two threaded blocks (54), the screw (52) rotates, thereby driving the two threaded blocks (54) connected to it to move, and driving the transmission of the connecting seat connected to the two threaded blocks (54), so that the angle of the two inclined support frames (55) changes, thereby driving the protective cover (4) to rise and fall vertically. At the same time, through the sliding cooperation of each slide groove (11) and the slider (3), the stability and sealing of the movement of the protective cover (4) are enhanced; at the same time, when the protective cover (4) is raised and lowered, the two sealing plates (42) move synchronously to ensure that the equipment always maintains a good sealing effect during the height adjustment process until the protective cover (4) is adjusted to a suitable height;

[0046] Then, the operator can use the sliding connection between the movable seat (81) and the guide rail (82) to move the equipment precisely to the top of the precast beam (10). Then, the sealing structure (6) is started by controlling the electrical control cabinet (9a), and the two sealing structures (6) are closed to achieve full sealing. Steam can then be delivered into the protective cover (4) through the steam generator (9).

[0047] Finally, the operator starts two first circulating fans (73) and two second circulating fans (74) through the electrical control cabinet (9a). Because the partition (71) divides the inside of the equipment into upper and lower areas, a set of first circulating fans (73) draws the bottom steam to the top, while a set of second circulating fans (74) returns the top steam to the bottom, which promotes the efficient circulation of steam in the curing space, ensuring that the precast beams and slabs are cured evenly and fully, and significantly improving the quality and efficiency of curing.

[0048] The beneficial effects of this utility model compared with the prior art are:

[0049] 1. This utility model is simple to operate, safe and reliable. By using a motor drive combined with the transmission of a threaded assembly, the height of the protective cover can be flexibly adjusted. In this way, the steam curing cover equipment is given a height self-adaptive function, which can seamlessly adapt to the curing needs of precast beams and slabs of different specifications. It ensures that the beams and slabs are completely within the curing space, so that the steam acts evenly on the surface and interior of the beams and slabs, effectively promoting the stable growth of concrete strength, improving the overall structural performance of the components, thereby significantly improving the curing quality and construction efficiency, and reducing the quality risks caused by uneven curing.

[0050] 2. This utility model has an ingenious design. By setting an adjustment mechanism, the height of the protective cover can be adjusted more flexibly. After the adjustment is completed, the protective cover is sealed by a sealing structure to form a closed loop and ensure the airtightness of the protective cover.

[0051] 3. This utility model, through the precise cooperation of the guide rail and the slider, enables the equipment to move smoothly along the track, significantly improving the convenience of equipment relocation and positioning efficiency at the construction site.

[0052] 4. This utility model enables the steam to circulate efficiently within the equipment through a built-in steam circulation component, ensuring that the steam is evenly distributed in the curing space, effectively eliminating temperature and humidity gradients, and thus ensuring that all parts of the precast beams and slabs receive balanced curing.

[0077] To make the technical means, inventive features, objectives, and effects of this utility model readily understandable, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0078] In summary, a more specific embodiment of this utility model is as follows:

[0079] Before using the aforementioned convenient precast beam and slab steam curing hood equipment, it needs to be manufactured and installed as a backup.

[0080] Example 1

[0081] As per the instruction manual Figures 5-11 The portable steam curing hood for precast beams and slabs shown includes a steam generator 9, and further includes:

[0082] Support frame 1, the support frames 1 are arranged opposite to each other, and each support frame 1 has a sliding groove 11 on two legs, and a sliding opening 12 is provided through the upper crossbeam of the support frame 1.

[0083] Side protective plate 2, which is connected between the two legs on both sides of the two support frames 1;

[0084] Slider 3 is slidably connected to four slide grooves 11;

[0085] The upper two ends of the protective cover 4 are movably inserted into the corresponding sliding openings 12. The two side plates of the protective cover 4 are movably inserted into the interior of the two side protective plates 2, and the ends of the two side plates of the protective cover 4 are connected to the corresponding sliders 3.

[0086] Adjustment mechanism 5 is connected between the two support frames 1 above, and is used to drive the protective cover 4 to move up and down.

[0087] Sealing structure 6, which is connected to the outside of each support frame 1;

[0088] The steam generator 9 is located outside one of the protective plates 2.

[0089] In this utility model, the working part of the steam generator 9 is provided through one of the side protective plates 2 for curing the precast beam slab 10 inside the protective cover 4. The connection between the steam generator 9 and the side protective plate 2 is a sealed connection.

[0090] Furthermore, the adjustment mechanism 5 includes:

[0091] The fixing frame 51 is symmetrically connected to the upper inner side of the two support frames 1, and a fixing hole is provided in the middle of the fixing frame 51;

[0092] The lead screw 52 has its two ends rotatably connected to the fixing holes of the fixing bracket 51;

[0093] The drive motor 53 is fixed on one of the fixed brackets 51 by a mounting bracket, and the working end of the drive motor 53 is connected to the lead screw 52 at that end.

[0094] Two thread blocks 54, the two thread blocks 54 are respectively screwed to both ends of the screw rod 52;

[0095] Two connecting seats, the upper ends of the two connecting seats are both connected to the lower end of the corresponding thread block 54, and the lower ends are connected to the top end surface of the protective cover 4.

[0096] Specifically, the screw rod 52 is a two-way screw rod, and both ends of the screw rod 52 are connected to the fixing holes of the fixing frame 51 through bearings.

[0097] Further, the connecting seat comprises: a diagonal brace 55; a first connecting seat 56, the upper end of the first connecting seat 56 is fixedly connected to the thread block 54, and the lower end is movably connected to the upper end of the diagonal brace 55; a second connecting seat 57, the upper end of the second connecting seat 57 is movably connected to the lower end of the diagonal brace 55, and the lower end is fixedly connected to the top end surface of the protective cover 4;

[0098] Wherein, the two diagonal braces 55 of the two connecting seats are arranged in a splayed shape.

[0099] In the present utility model, the two-way screw rod is driven to rotate by the driving motor 53. Based on the principle of screw transmission, the two thread blocks 54 are driven to move in opposite directions, thereby changing the included angle of the two connecting seats. The change in the angle of the diagonal brace 55 promotes the protective cover 4 to lift in the vertical direction, realizing flexible adjustment of the height of the steam curing equipment, so that it can adapt to prefabricated beam slabs 10 of different heights, and ensuring that all types of prefabricated beam slabs 10 can obtain comprehensive and effective steam curing.

[0100] Further, the support frame 1 is generally in a C-shaped structure; an accommodation compartment is provided inside the side protective plate 2.

[0101] In the present utility model, the cross-section of the side protective plate 2 is C-shaped.

[0102] Further, the protective cover 4 comprises: a protective cover body 41, the protective cover body 41 is generally in a C-shaped structure; sealing plates 42, the sealing plates 42 are symmetrically and vertically connected to the ends of the two top ends of the protective cover body 41, and the sealing plates 42 are movably inserted into the sliding ports 12 at the corresponding ends.

[0103] Further, the sealing structure 6 is a rolling shutter door assembly, and the rolling shutter door assembly is respectively installed on the outer side of each support frame 1, for sealing the opening of each support frame 1.

[0104] In the present utility model, the rolling shutter door assembly can provide a convenient access passage and reliable sealing protection for the steam curing equipment. It can be quickly opened when the prefabricated beam slab 10 enters and exits, and effectively prevents steam leakage after being closed in cooperation with the sealing structure. Meanwhile, the steam generator 9 can continuously and stably generate high-temperature steam, provide sufficient heat source for curing the prefabricated beam slab 10, and deliver the steam to the curing space through pipes, so as to maintain a suitable curing temperature and humidity environment.

[0105] Furthermore, an electrical control cabinet 9a is also provided outside the protective plate 2 on the same side of the steam generator 9. The electrical control cabinet 9a is electrically connected to the drive motor 53 of the steam generator 9 and the regulating mechanism 5.

[0106] The specific working principle is as follows: During use, the operator first adjusts the height of the protective cover 4 according to the height of the precast beam slab 10 to adapt to precast beam slabs 10 of different specifications. When adjusting the height of the protective cover 4, the operator first starts the drive motor 53, whose output end drives the lead screw 52 to rotate. Because the threads on both sides of the lead screw 52 are reversed and threadedly connected to two threaded blocks 54, the rotation of the lead screw 52 drives the two threaded blocks 54 connected to it to move, and drives the transmission of the connecting seat connected to the two threaded blocks 54, so that the angle of the two inclined support frames 55 changes, thereby driving the protective cover 4 to rise and fall vertically. At the same time, through the sliding cooperation of each slide groove 11 and the slider 3, the stability and sealing of the movement of the protective cover 4 are enhanced. At the same time, when the protective cover 4 is raised and lowered, the two sealing plates 42 move synchronously to ensure that the equipment maintains a good sealing effect during the height adjustment process. When the protective cover 4 is adjusted to a suitable height;

[0107] Then, the operators transport the precast beams 10 into the protective cover 4 and place them for curing.

[0108] Next, after the operators placed the precast beams 10, they controlled the sealing structure 6 to start through the electrical control cabinet 9a, closing the openings of the two support frames 1 to achieve full enclosure;

[0109] Finally, the operator starts the steam generator 9 through the electrical control cabinet 9a, which can then be used to cure the precast beams and slabs 10 inside the protective cover 4.

[0110] Example 2

[0111] As per the instruction manual Figures 7-9 As shown, this embodiment 2 is basically the same as embodiment 1, except that it also includes a steam circulation assembly 7 disposed inside the protective cover 4. The steam circulation assembly 7 includes:

[0112] Partition 71 is connected to the upper part of the protective cover 4, and ventilation holes 72 are provided at the four corners of partition 71.

[0113] The first circulating fan 73 is installed in two ventilation holes 72 on the same side or different sides respectively;

[0114] The second circulating fan 74 is installed in two other ventilation holes 72.

[0115] In this invention, an electrical control cabinet 9a is fixedly installed on one side of the outer wall of one of the two protective plates 2. The first circulating fan 73 and the second circulating fan 74 are both electrically connected to the electrical control cabinet 9a. A partition 71 is fixedly connected to the inner wall of the protective cover 4. The electrical control cabinet 9a can intelligently control and manage the maintenance equipment, realize the start-stop regulation, parameter setting, and operation status monitoring of equipment such as the steam generator 9, drive motor 53, first circulating fan 73, and second circulating fan 74. The partition 71 can divide the interior of the maintenance equipment into two spaces, constructing independent steam circulation channels, which facilitates the optimization of steam pipeline layout and airflow organization.

[0116] Two sets of ventilation holes provide a flow channel for steam circulation; two first circulation fans 73 use negative pressure to directionally draw steam from the bottom of the curing equipment to the top space; two second circulation fans 74 draw steam from the top back to the bottom, ensuring efficient circulation of steam in the curing space, thereby ensuring the uniformity of temperature and humidity in the curing space and avoiding local temperature differences or uneven steam concentration.

[0117] During use, since a steam circulation assembly 7 is installed inside the protective cover 4, when in use, two first circulation fans 73 and two second circulation fans 74 are started. Because the partition 71 divides the inside of the equipment into upper and lower areas, a set of first circulation fans 73 draws the steam from the bottom to the top, while a set of second circulation fans 74 returns the steam from the top to the bottom, which promotes the efficient circulation of steam in the curing space, ensuring that the precast beams and slabs are cured evenly and fully, and significantly improving the quality and efficiency of curing.

[0118] Example 3

[0119] As per the instruction manual Figures 1 to 4 and Figure 12 as well as Figure 13 As shown, this embodiment 3 is basically the same as embodiment 2, except that it also includes a translation component 8, which includes:

[0120] Movable base 81, which is connected to the bottom of the two side protective plates 2 respectively;

[0121] Guide rail 82 is movably inserted into two movable seats 81.

[0122] In this utility model, the bottom of each of the two side protective plates 2 is fixedly connected with a movable seat 81, and the inner surface of each of the two movable seats 81 is movably inserted with a guide rail 82. Through the sliding cooperation between the guide rail 82 and the movable seat 81, the protective cover 4 can achieve stable and flexible displacement along the guide rail 82, effectively reducing the moving resistance and operation difficulty of the equipment on the construction site, and enhancing the convenience of using the equipment.

[0123] During use, since there are also translation components 8 under both side protective plates 2, when the protective cover 4 is adjusted to a suitable height, the equipment can be accurately moved to the top of the precast beam 10 by using the sliding connection between the two movable seats 81 and the guide rail 82. Then, the two sealing structures 6 are closed to achieve full enclosure, and steam can be delivered into the protective cover 4 through the steam generator 9, avoiding the many inconveniences caused by transporting and placing the precast beam 10 in the narrow protective cover 4.

[0124] Preferably, the operator can place the precast beam 10 inside the guide rail 82, and then adjust the protective cover 4 to a suitable height. The operator can then push the protective cover 4, and with the cooperation of the translation component 8, quickly move the protective cover 4 onto the precast beam 10. After that, the two sealing structures 6 are closed to achieve full sealing, and steam can be delivered into the protective cover 4 through the steam generator 9.

[0125] During use, the operator first adjusts the height of the protective cover 4 according to the height of the precast beam slab 10 to accommodate precast beam slabs 10 of different specifications. When adjusting the height of the protective cover 4, the operator first starts the drive motor 53, whose output end drives the lead screw 52 to rotate. Because the threads on both sides of the lead screw 52 are reversed and threadedly connected to two threaded blocks 54, the rotation of the lead screw 52 drives the two threaded blocks 54 connected to it to move, and drives the transmission of the connecting seat connected to the two threaded blocks 54, so that the angle of the two diagonal braces 55 changes, thereby driving the protective cover 4 to rise and fall vertically. At the same time, the sliding cooperation between each slide groove 11 and the slider 3 enhances the stability and sealing of the movement of the protective cover 4. At the same time, when the protective cover 4 is raised and lowered, the two sealing plates 42 move synchronously to ensure that the equipment maintains a good sealing effect during the height adjustment process until the protective cover 4 is adjusted to the appropriate height.

[0126] Then, the operator can precisely move the equipment to the top of the precast beam 10 by using the sliding connection between the movable seat 81 and the guide rail 82. Then, the sealing structure 6 is started by controlling the electrical control cabinet 9a, and the two sealing structures 6 are closed to achieve full sealing. Steam can then be delivered into the protective cover 4 through the steam generator 9.

[0127] Finally, the operator starts two first circulating fans 73 and two second circulating fans 74 through the electrical control cabinet 9a. Because the partition 71 divides the inside of the equipment into upper and lower areas, a set of first circulating fans 73 draws the steam from the bottom to the top, while a set of second circulating fans 74 returns the steam from the top to the bottom, which promotes the efficient circulation of steam in the curing space, ensuring that the precast beams and slabs are cured evenly and fully, and significantly improving the quality and efficiency of curing.
