Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a movable steaming shed. Background Art

[0002] In the field of construction, winter is the most difficult season for precast concrete construction. Steam curing of precast beams is a crucial link to ensure the strength and durability of precast beams. The currently used intelligent curing technology can solve the above problems, but the use of this technology requires a large initial capital investment and has certain requirements for the output of precast parts. It is difficult to ensure the flatness and tightness of the steam curing cloth when it is manually laid. The steam curing cloth may be wrinkled or overlapped during the laying process, resulting in some areas not being fully steam-cured, which will affect the strength and durability of the precast beams. At the same time, the temperature difference is relatively large in winter. After the precast beams have reached a certain strength after curing, the construction personnel need to cover the precast beams immediately after demolding or continue curing in other ways, otherwise the concrete precast parts will produce shrinkage cracks and affect the construction quality. The covering materials at the construction site are mostly made of heavy canvas or plastic sheets. Although these materials have certain heat preservation and moisture retention effects, they are often heavy and large in size, requiring the cooperation of multiple workers during the laying and removal process. However, this method that relies on manpower is not only inefficient, but also prone to safety hazards when the beam is high.

[0003] The Chinese patent publication number CN219381004U discloses an intelligent fully automated steaming rack for prefabricated components. Although the patent realizes the effect of fast transfer and reduces manual reciprocating transportation, in actual steaming operations, the lengths of the prefabricated components are usually different. The patent is not convenient for adaptive adjustment according to the length of the prefabricated components, and has limitations.

[0004] Therefore, in view of this, the inventor proposes a movable steaming shed to solve the above technical problems. Utility Model Content

[0005] One purpose of the utility model is to provide a movable steaming shed to solve the problem that it is inconvenient to lay and remove the steaming cloth when steam curing prefabricated beams; the second purpose is to solve the problem that the steaming structure is not easy to adjust.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A movable steaming shed comprises a steaming frame, wherein the steaming frame comprises a supporting frame and an adjusting member, wherein the number of the supporting frames is at least two, and the supporting frames are arranged parallel to each other, and the adjusting member is located between two adjacent supporting frames and is used to connect the two adjacent supporting frames;

[0008] It also includes a steaming cloth and two guide rails. The steaming cloth is installed on the steaming frame and can be enclosed to form a closed frame structure. The steaming frame is installed on the two guide rails and can move along the length direction of the two guide rails.

[0009] According to the above technical solution, the steaming rack is composed of at least two support racks, which are arranged parallel to each other to provide a stable support structure for the steaming cloth. The adjusting piece is used to connect adjacent support racks. One end of the second connecting rod extends into the first connecting rod and is slidably connected thereto. Such a design allows the staff to flexibly adjust the distance between the support racks as needed. By sliding the second connecting rod to change the spacing between the support racks, it can adapt to prefabricated beams of different lengths, or adjust the size of the steaming space according to actual needs; the steaming cloth is installed on the steaming rack, and it can be easily enclosed into a closed frame structure. Compared with the prior art, the laying and removal process of the steaming cloth is simplified, the work efficiency is improved, and the operation difficulty is reduced. When the prefabricated beam needs to be steamed, it is only necessary to enclose the steaming cloth on the support rack to form a closed space, and then introduce steam for curing.

[0010] Furthermore, the support frame includes a skeleton, and the skeleton includes a top support and two support rods, and the two support rods are respectively connected to two ends of the top support and fixedly connected to the top support.

[0011] Furthermore, the support frame also includes two lifting units, which are detachably mounted on the bottom of a corresponding one of the support rods, and the two lifting units can rise or fall to drive the frame to rise or fall.

[0012] According to the above technical solution, the support frames are placed in parallel and connected by adjusting parts. The adjusting parts allow the spacing between adjacent support frames to be adjusted to meet different needs. The lifting unit can rise or fall, thereby driving the skeleton to rise or fall. When the site of the prefabricated beam construction site is uneven, the lifting unit can be used to make adaptive adjustments to maintain the stability of the entire structure and avoid the possibility of wrinkles or overlaps in the steam-cured cloth during the laying process.

[0013] Further, the lifting unit includes a rolling member, a limiting member, a first support rod and a second support rod, one end of the second support rod extends into the first support rod and is slidably connected to the first support rod, and the limiting member is used to limit the second support rod from sliding in the first support rod;

[0014] The top of the first support rod is connected to the support rod, and the other end of the second support rod is connected to the rolling element.

[0015] According to the above technical solution, the second strut in the lifting unit can slide inside the first strut, that is, the second strut can move up and down inside the first strut, thereby changing the height of the entire lifting unit. In order to ensure that the lifting unit can remain stable after being adjusted to a suitable height, a limiter is used to fix the position of the second strut inside the first strut. When lifted to the desired height, the lifting unit can be firmly locked in this position.

[0016] Furthermore, the first support rod is provided with a plurality of first limiting holes, the second support rod is provided with a plurality of second limiting holes, and the limiting member can pass through the first limiting holes and the second limiting holes to limit the first support rod and the second support rod.

[0017] According to the above technical solution, the limiting member can pass through the corresponding first limiting hole and the second limiting hole. When the second support rod slides to a certain position inside the first support rod, the limiting member can pass through the corresponding limiting hole to fix the relative position between the two, thereby ensuring the stability and load-bearing capacity of the lifting unit. The limiting member passes through the corresponding different first limiting holes and the second limiting holes to lock the position of the support rod, thereby completing the lifting and lowering adjustment of the lifting unit.

[0018] Further, the support rod comprises a first vertical rod, a second vertical rod and a vertical rod connecting column, the second vertical rod is located above the first vertical rod, and the vertical rod connecting column is located between the first vertical rod and the second vertical rod; the first vertical rod and the second vertical rod can be moved closer to or farther from each other through the vertical rod connecting column;

[0019] The first vertical rod is connected to the first support rod, and the second vertical rod is connected to the top support; the support frame also includes a rib rod, which is located at the connection between the second vertical rod and the top support, one end of the rib rod is connected to the second vertical rod, and the other end of the rib rod is connected to the top support.

[0020] According to the above technical solution, during the steaming process, the weight of the steaming cloth may cause pressure on the support frame, resulting in structural deformation. By setting the rib rods at the connection between the second vertical rods and the top support, a triangular structure is formed between the second vertical rods, the rib rods and the top support, which helps to reduce structural deformation and improve the overall structural strength.

[0021] Furthermore, a clamping plate is provided below the lifting unit, and a plurality of chains are distributed on both sides of the guide rail, one end of the chain is fixedly mounted on the guide rail, and the other end of the chain is used to be connected to the clamping plate.

[0022] Furthermore, the steam-curing cloth comprises a first covering portion and second covering portions located at both ends of the first covering portion, and the second covering portions can be folded;

[0023] A plurality of hooks are arranged around the first covering part and the second covering part, and a plurality of hanging holes are opened at the bottom of the first covering part and the second covering part, and the hanging holes are arranged corresponding to the hooks.

[0024] According to the above technical solution, the steaming cloth consists of a first covering part and two second covering parts located at both ends of the first covering part. When the steaming rack is moved, the second covering part can be folded and rolled up for easy movement; when the prefabricated beam needs to be steamed, the second covering part can be put down, and the structure is compact and practical; a number of hooks are arranged around the first covering part and the second covering part, and these hanging holes correspond to the hooks on the covering part; when the prefabricated beam needs to be steamed, the bottom of the first covering part and the second covering part will be put down and contact the ground, which can ensure that the steaming space achieves a better sealing effect and prevents steam leakage; when the steaming is completed, in order to facilitate the movement of the steaming rack and the next round of steaming operation, the bottom of the first covering part and the second covering part are folded upwards, and the bottom of the first covering part and the second covering part are hung on the hooks through the hanging holes and then hung again for easy movement.

[0025] Furthermore, the adjusting member includes a first connecting rod and a second connecting rod, and one end of the second connecting rod extends into the first connecting rod and is slidably connected to the first connecting rod.

[0026] Furthermore, the adjusting member includes two connecting rods arranged crosswise with each other, the connecting rod is located between two adjacent support rods, one end of the connecting rod is hinged to one of the support rods, and the other end of the connecting rod is slidably connected to the other support rod.

[0027] Beneficial effects of the utility model:

[0028] The traditional operation method is to manually lay the steam-curing cloth. It is difficult to ensure the flatness and tightness of the steam-curing cloth. The steam-curing cloth may be wrinkled or overlapped during the laying process, resulting in some areas not being fully steam-cured. This will not only affect the strength and durability of the prefabricated beams, but may also cause safety hazards. The steam-curing rack of the utility model can be moved on the guide rail, which is simple to operate and convenient for steam curing operations. At the same time, after the steam-curing rack is installed in place and connected to the guide rail, it has a wind-resistant effect. When the construction site is uneven, the guide rail can also be adaptively adjusted according to the construction site, and on-site construction is carried out, with a compact structure and strong practicality.

[0029] The utility model uses the sliding connection mode of the first connecting rod and the second connecting rod to flexibly adjust the length of the steaming rack to adapt to different scenes and needs. At the same time, the design of the lifting unit also allows the height of the steaming rack to be adjusted, further improving the flexibility and convenience of use, and the setting of the rolling part allows the entire steaming structure to be easily moved, greatly improving the convenience of use and facilitating movement.

[0030] The fixed connection between the top support and the support rod ensures the stability of the steaming frame. At the same time, the design of the steaming cloth allows it to completely cover the steaming frame to form a closed frame structure, which not only ensures the steaming effect, but also makes the structure suitable for prefabricated beams of various shapes and sizes for steaming, avoiding the problem of incomplete steaming coverage affecting the quality of steaming.

The two support rods 212 are respectively connected to both ends of the top support 211 and are fixedly connected to the top support 211 .

[0053] Furthermore, the support frame 2 further includes two lifting units 22, which are detachably mounted at the bottom of the corresponding support rod 212, and the two lifting units 22 can rise or fall to drive the frame 21 to rise or fall. When the site of the prefabricated beam construction site is uneven, the staff can make adaptive adjustments through the lifting units 22 to maintain the stability of the entire structure and avoid the possibility of wrinkles or overlaps in the steam-cured cloth 4 during the laying process.

[0054] In one possible implementation, due to Fig. 9 As shown, a snap plate 521 is further provided below the lifting unit 22, and a plurality of chains 52 are distributed on both sides of the guide rail 5.

According to the above technical solution, the second support rod 224 can move up and down inside the first support rod 223, thereby changing the height of the entire lifting unit 22. In order to ensure that the lifting unit 22 can remain stable after being adjusted to a suitable height, a limiter 222 is used to fix the position of the second support rod 224 in the first support rod 223. When the lifting unit 22 is lifted to the desired height, it can be firmly locked in this position.

[0056] Furthermore, the rolling member 221 is a self-locking caster, and the self-locking caster is made of metal. According to the above technical solution, the rolling member 221 adopts a self-locking caster, which has a self-locking function, can prevent accidental movement, and ensure structural stability. The self-locking caster made of metal has high strength and rigidity and can adapt to the harsh high temperature environment of steam curing.

[0057] Furthermore, if Figure 5 As shown, a plurality of first limiting holes 2231 are formed on the first support rod 223, and a plurality of second limiting holes 2232 are formed on the second support rod 224. The limiting member 222 can pass through the first limiting holes 2231 and the second limiting holes 2232 to limit the first support rod 223 and the second support rod 224. When the second support rod 224 slides to a certain position inside the first support rod 223, the limiting member 222 can pass through the corresponding limiting holes to fix the relative position between the two, thereby ensuring the stability and load-bearing capacity of the lifting unit 22; the limiting member 222 passes through the corresponding different first limiting holes 2231 and the second limiting holes 2232 to lock the position of the support rod, and the lifting and lowering adjustment of the lifting unit 22 is completed.

The way in which the stopper 222 fixes the first vertical rod 2121 and the second vertical rod 2122 to the vertical rod connecting column 2123 is similar to the way in which the first support rod 223 and the second support rod 224 are fixed to the stopper 222 in the above-mentioned embodiment, and will not be described in detail in this embodiment. According to the above-mentioned technical solution, by adjusting the distance between the first vertical rod 2121 and the second vertical rod 2122, the overall length of the support rod 212 can be changed, thereby adjusting the height of the steaming rack 1 or adapting to prefabricated beams of different lengths.

[0059] As a preferred embodiment, Figure 2 and Figure 3 As shown, the support frame 2 further includes a rib bar 23, which is located at the connection between the second vertical bar 2122 and the top support 211, one end of the rib bar 23 is connected to the second vertical bar 2122, and the other end of the rib bar 23 is connected to the top support 211. During the steaming process, the weight of the steaming cloth 4 may cause pressure on the support frame 2, resulting in structural deformation, and by arranging the rib bar 23 at the connection between the second vertical bar 2122 and the top support 211, a triangular structure is formed between the second vertical bar 2122, the rib bar 23 and the top support 211, which helps to reduce structural deformation and improve the overall structural strength.

[0060] As a preferred embodiment, Figure 1 As shown, the steaming cloth 4 includes a first covering portion 41 and second covering portions 42 located at both ends of the first covering portion 41, and the second covering portion 42 can be folded; a plurality of hooks 411 are provided around the first covering portion 41 and the second covering portion 42, and a plurality of hanging holes 421 are opened at the bottom of the first covering portion 41 and the second covering portion 42, and the hanging holes 421 are arranged corresponding to the hooks 411.

[0061] According to the above technical solution, the steaming cloth 4 is composed of a first covering part 41 and two second covering parts 42 located at both ends of the first covering part 41. When the steaming rack 1 is moved, the second covering part 42 can be folded and rolled up for easy movement; when the prefabricated beam needs to be steamed, the second covering part 42 can be put down, and the structure is compact and practical; a plurality of hooks 411 are arranged around the first covering part 41 and the second covering part 42, and these hanging holes 421 correspond to the hooks 411 on the covering part; when the prefabricated beam needs to be steamed, the bottom of the first covering part 41 and the second covering part 42 will be put down and contact the ground, so as to ensure that the steaming space achieves a better sealing effect and prevents steam leakage; when the steaming is completed, in order to facilitate the movement of the steaming rack 1 and the next round of steaming operation, the bottom of the first covering part 41 and the second covering part 42 are folded upwards, hung on the hooks 411 through the hanging holes 421, and hung again for easy movement.

[0062] According to the above technical solution, the steaming rack 1 is composed of at least two support racks 2, which are arranged in parallel with each other to provide a stable support structure for the steaming cloth 4. The adjusting member 3 is used to connect adjacent support racks 2, and one end of the second connecting rod 32 extends into the first connecting rod 31 and is slidably connected thereto. Such a design allows the staff to flexibly adjust the distance between the support racks 2 as needed, and change the spacing of the support racks 2 by sliding the second connecting rod 32, so as to adapt to prefabricated beams of different lengths, or adjust the size of the steaming space according to actual needs; the steaming cloth 4 is installed on the steaming rack 1, which can be easily enclosed into a closed frame structure. Compared with the prior art, the laying and removal process of the steaming cloth 4 is simplified, the work efficiency is improved, and the operation difficulty is reduced. When the prefabricated beam needs to be steamed, the steaming cloth 4 only needs to be enclosed on the support rack 2 to form a closed space, and then steam is introduced for curing.

[0063] Embodiment 2:

[0064] The difference between the second embodiment and the first embodiment is that the adjustment member 3 is improved.

When the precast beam needs to be steam-cured, the adjacent support rods 212 are pulled to unfold the steaming rack 1; when the steaming rack 1 needs to be stored, the adjusting member 3 in this embodiment can greatly compress the space occupied by the steaming rack 1, making it convenient to store.

[0065] Compared with the existing intelligent curing technology, the present invention has a compact structure, does not require a large amount of capital investment, and does not require the prefabricated parts to meet certain requirements. Compared with the traditional manual laying of the steam-curing cloth 4, it is difficult to ensure the flatness and tightness of the steam-curing cloth 4. The steam-curing cloth 4 may be wrinkled or overlapped during the laying process, resulting in that some areas cannot be fully steam-cured, which not only affects the strength and durability of the prefabricated beam, but also may cause safety hazards. The present invention installs the steam-curing frame 1 on the guide rail 5, and the steam-curing frame 1 can be moved on the guide rail 5. The operation is simple, the investment is small, and the steam curing operation is convenient. When the construction site is uneven, the height of the guide rail 5 can also be adaptively adjusted according to the construction site to ensure that the guide rail 5 is flush, and the construction is carried out on the spot, with a compact structure and strong practicality. Moreover, the design of the steam-curing cloth 4 allows it to completely cover the steam-curing frame 1 to form a closed frame structure, which not only ensures the steam-curing effect, but also avoids the problem of incomplete steam-curing coverage and affecting the quality of steam-curing.

[0066] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by a person skilled in the art based on the present invention is within the protection scope of the present invention.
