Description

Technical Field

[0001] The invention relates to the technical field of prefabricated beam manufacturing, and in particular to an omnidirectional steaming device for prefabricated beams. Background Art

[0002] Precast beams, also known as large precast concrete beams, are one of the commonly used structural components in engineering construction. After standardized and normalized production in the factory, they are transported to the construction site for installation; precast box beam steam curing equipment is a kind of equipment used for the curing of precast box beams. It adopts steam heating method, and heats the precast box beams by passing steam into them to achieve the purpose of curing.

[0003] At present, fixed steaming sheds are generally used for steaming, which are equipped with nozzles inside. Mobile steaming sheds are also used for steaming, such as the utility model patent with patent number 202121473374.7 in the prior art, which discloses an adjustable steaming shed. An adjustable steaming shed includes side enclosure columns on both sides of the greenhouse, and the side enclosure columns are arranged in multiple groups at intervals along the length direction of the greenhouse. The spacing between the side enclosure columns on the same side is adjustable, and the upper ends of the side enclosure columns are provided with roof arc rods, and the ends of the roof arc rods at the upper ends of the side enclosure columns on both sides form a telescopic fit.

[0004] However, the internal steam curing structure of the precast beam in the prior art is relatively simple, and the water pipes and the nozzles are directly arranged inside the precast beam. When the interior of the precast beam is steam-cured, the moisture generated by the steam curing will be retained in the precast beam, and the bottom of the precast beam will be soaked in the spray water for a long time, resulting in uneven curing inside the precast beam, and then causing the following disadvantages; Uneven strength: If the curing distribution is uneven during the curing process, it may lead to different hardening degrees inside the concrete, making the strength of each part of the precast beam inconsistent. The lower strength part is prone to damage when bearing load, affecting the safety and stability of the entire structure.

[0005] Deformation and cracking: Uneven curing may also cause uneven shrinkage and expansion of precast beams, leading to deformation and cracking. These deformations and cracks not only affect the appearance quality of the beams, but may also reduce their bearing capacity and even lead to structural failure.

[0006] Reduced durability: Uneven curing will affect the compactness and impermeability of concrete, making precast beams more susceptible to corrosion by moisture, oxygen and other harmful substances. Over a long period of time, concrete may suffer from durability problems such as carbonization and steel corrosion, shortening the service life of precast beams.

[0007] Safety hazards: Uneven strength, deformation, cracking and reduced durability caused by uneven steaming may have an adverse effect on the safety performance of precast beams. In extreme cases, it may cause serious accidents such as fracture or collapse of precast beams during service, threatening people's lives and property.

[0008] Based on this, it is necessary to study a comprehensive steaming device for prefabricated beams. Summary of the invention

[0014] Furthermore, a reinforcement seat for reinforcing the collecting head is led out from the lower part of the collecting core, and a filter head is arranged at the lower part of the collecting head.

[0015] Furthermore, a connecting portion with an internal thread is provided on the upper portion of the filter cover body, the connecting portion is threadedly connected to the outer side of the steaming seat, and the lower portion thereof is a mesh filter portion.

This structure is easy to store and unfold, and can easily form a track foundation inside the prefabricated beam. The steaming rack is configured on the double rope track, so that the steaming rack can be quickly and spaced apart in the prefabricated beam, thereby improving construction efficiency.

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Embodiment 1, this embodiment aims to provide a precast beam omnidirectional steaming device, which is mainly used for steaming precast beams. In the production process of precast beams, steaming is a key process link, which directly affects the quality and performance of precast beams. Traditional steaming devices often have problems such as uneven steaming and poor curing effect, resulting in unstable quality of precast beams and affecting engineering safety. Based on this, this embodiment provides a precast beam omnidirectional steaming device, which realizes omnidirectional curing of precast beams during the steaming process, and improves the quality and steaming efficiency of precast beams.

[0028] like Figure 1 As shown in the figure, a prefabricated beam omnidirectional steaming device comprises a mobile steaming shed 4, a fixed steaming shed 6 and an internal steaming assembly; the mobile steaming shed 4 is located at the front end of the fixed steaming shed 6 and is used for preliminary steaming of the prefabricated beam with a mold; in terms of structure, Figure 1 As shown in , this embodiment performs steam curing with a mold in the casting and steam curing area according to the precast beam production process, and performs synchronous steam curing inside and outside the steam curing area, so that curing can be performed one step before the precast beam concrete is demolded, which accelerates the steam curing intervention time and effectively reduces the curing cycle. Steam curing in a fixed curing room once or twice enables the strength of the beam to increase progressively over time, and can effectively alleviate the problem of insufficient space and waiting in line for curing after the precast beam is cast, greatly shortening the curing time.

[0029] In order to achieve this purpose, the mobile steaming and curing shed 4 in this embodiment includes columns 1, tracks 2, mobile frames 3, steaming and curing sheds and nozzles; the columns 1 are distributed on both sides, and tracks 2 are arranged on the inner sides of the two columns 1, and the mobile frames 3 are arranged on the tracks 2 on both sides through mobile wheels; the mobile steaming and curing shed 4 is fixed on the mobile frame 3, and a first nozzle 5 is arranged on the inner side of the mobile steaming and curing shed 4, and the first nozzle 5 is connected to the external steam boiler through a water pipe; this structure provides a mobile steaming and curing structure to perform preliminary steaming and curing on the prefabricated beams.

[0030] The fixed steaming shed 6 is arranged in the steaming area, which is located at the rear side of the pouring steaming area. In the specific structure, the fixed steaming shed 6 includes a main structure, internal steaming components and a ground rail; the main structure as a whole is as shown in FIG. Figure 2-3 As shown in the figure, the main structure is a U-shaped structure, and second nozzles 7 facing inward are arranged on both sides of the inner wall of the main structure. The second nozzles 7 are used to maintain the outside of the precast beams. The ground rails 8 are arranged in the middle area of ​​the main structure and are equipped with a transport seat 9 for moving the precast beams.

[0031] In this embodiment, Figure 2-5 As shown in the figure, the internal steaming assembly includes a double rope track 13, a steaming frame 11, a steaming seat 14, a filter cover 19, a third nozzle 16, a collecting core 21 and a collecting head 22; wherein a rope pulley 12 is arranged in the middle of the steaming frame 11, and support frames are provided on both sides of the prefabricated beam 10, and both ends of the double rope track 13 are arranged on the support frames, so that the double rope track 13 passes through the interior of the prefabricated beam 10 and provides a moving support point for the rope pulley; in order to facilitate storage, a rope pulley is arranged on the support frame on one side, one side of the double rope track is wound on the winding roller, and the other side thereof is fixed on the support frame on the opposite side, so that the track rope serving as the track can be quickly unfolded and wound on the winding roller.

[0032] In the specific structure, the rope pulley 12 is a wheel body structure with a groove, which is fixed on both sides of the middle of the prefabricated beam 10. In order to ensure the symmetry of the structure and the center is centered, and to facilitate the stability of the movement and storage process, the steaming rack 11 in this embodiment is configured as a hollow trapezoidal structure, and clamping sleeves 15 are fixed on both sides of the steaming rack 11. The clamping sleeves 15 are fixedly sleeved on the outside of the steaming seat 14. The steaming rack 11 is a symmetrical trapezoidal structure, and a middle reinforcement plate 20 is arranged in the middle, and the rope pulley is located on both sides of the middle reinforcement plate 20. The middle reinforcement plate 20 can ensure the structural stability and strength of the steaming rack.

[0033] like Figure 6As shown in the figure, steaming seats 14 are fixed on both sides of the steaming frame 11, and a third nozzle 16 is fixedly provided on the upper part of the steaming seat 14. A mounting hole 162 is provided at the upper center of the steaming seat 14. The bottom of the third nozzle 16 is threadedly installed in the mounting hole 162 through a mounting head 161. A docking joint 163 is led out on both sides of the third nozzle 16. The docking joint is used to install a soft steaming pipe. This structure can facilitate the installation and disassembly of the third nozzle 16, and the overall structure can be assembled.

[0034] A filter cover 19 is provided at the lower part of the steam curing seat 14, and a collection area exists inside the filter cover 19 and the steam curing seat 14. A collecting core 21 is provided on the steam curing seat 14, and a collecting head 22 extends into the collection area. A plurality of steam curing racks 11 are arranged in parallel, and adjacent collecting cores 21 and the steam curing seat 14 are linearly connected by corresponding collecting pipes 18 and steam curing pipes 17, wherein the steam curing pipe 17 is connected to an external steam boiler, and the collecting pipe 18 is connected to a pump, which is a negative pressure pump and provides suction force, and each collecting core 21 is connected through the collecting pipe, so that negative pressure exists at the end of the collecting head 22.

[0035] like Figure 8 As shown in , in a further implementation structure, a fourth nozzle 25 can be arranged in the middle of the steaming frame 11. The fourth nozzle 25 has the same structure as the third nozzles 16 on both sides and is connected through pipelines and to an external steam boiler, thereby providing steaming points in the middle and both sides of the precast beam. The steaming pipes on both sides and the steaming pipes in the middle can be connected to a main pipe, which is connected to the steaming boiler.

[0036] In this embodiment, the pipe connecting the steam curing seat 14 and the collecting core 21 is a flexible PVC steel wire composite pipe, which has certain flexibility and strength, and can be adaptively stored and deformed, or each pipe can be disassembled section by section when stored; the steam boiler uses a biomass energy boiler for steam curing. Biomass energy steam boilers are widely used, have the advantages of green environmental protection, clean process and low pollution, and mainly burn biomass particles. Biomass particles use wood chips and straw as fuel, so the cost is relatively low and the economy is high. At the same time, solar energy is used to increase the water temperature, which saves fuel combustion and reduces costs.

[0037] The steam pipeline is transmitted from the boiler to the curing shed. The main steam pipe is equipped with a pressure regulating valve, a throttle valve, an electrically operated mechanical regulator for adjusting the steam flow, and a stop valve as the main switch valve: each auxiliary pipe is a stainless steel pipe, and a steam spray hole with a diameter of 2 to 3 mm is provided every 2m in the steaming room. When configuring, the auxiliary pipe is placed longitudinally on the wall of the steaming shed under the bottom plate. The pipeline of the mobile steaming shed 4 is arranged at the lower part of the wall in the same way, and a hose connected to the external main pipe is provided at the end of the shed to steam and cure the concrete products at the same time.

[0038] Therefore, when this embodiment is in use, the prefabricated beam is first moved into position, and then support frames are set up on both sides of the prefabricated beam, and the steaming frame 11 is arranged at the front end, so that the double rope rail passes through all the steaming frames 11, and is led out from the middle of the prefabricated beam to the other side, and is fixed. After the double rope rail is configured, the steaming frames 11 are moved to each point one by one. Of course, the position points can be arranged on the double rope rail, and the steaming frames 11 are arranged oppositely. Then, the height of the double rope rail and the speed of the pump are adjusted so that the filter cover 19 touches the ground or is at a certain height, and the steaming boiler is started. The steaming water generated will accumulate at the bottom of the prefabricated beam, and then the negative pressure pump is started to pump out the accumulated water in time to avoid the problem of uneven maintenance caused by the accumulation of water inside the prefabricated beam.

[0039] Embodiment 2: This embodiment further illustrates the structure of the collecting core 21.

[0040] like Figure 6 As shown in the figure, in this embodiment, the collecting core 21 is fixed in the steaming seat 14, and there is a cavity in the collecting core 21. A base 24 is arranged at the bottom of the collecting core 21, and a collecting area is formed between the two sides of the base 24 and the filter cover 19. A central hole for avoiding the base is arranged in the middle of the filter cover 19, and the collecting heads 22 are distributed on both sides of the base. A collecting joint is led outward from the collecting core 21.

[0041] A reinforcement seat for reinforcing the collecting head 22 is led out from the lower part of the collecting core 21 , and a filter head 23 is arranged at the lower part of the collecting head 22 , thereby improving the structural stability of the collecting head 22 .

[0042] In this embodiment, the base is used for ground support, so that the filter cover body 19 is higher than the ground, avoiding the filter cover body 19 from bearing all the loads, and at the same time keeping a certain distance between the filter cover body 19 and the ground, such as placing the filter cover body 19 higher than 2 mm when placing it, and providing a support point by the reinforcement seat.

[0043] Furthermore, the upper part of the filter cover 19 is provided with a connection part 191 with an internal thread, and the connection part 191 is threadedly connected to the outer side of the steaming seat 14, and the lower part thereof is a mesh filter part 192. Combined with the base structure, the position of the filter cover 19 can be quickly adjusted through the threaded adjustment connection structure to achieve the adjustment of the water filtration depth.

[0044] Embodiment 3: This embodiment further illustrates the structure of the steaming rack 11.

[0045] like Figure 8 As shown in the figure, an adjustment seat 26 is provided at the bottom of the steaming rack 11, and the adjustment seat 26 can move up and down along the steaming rack 11, and a moving wheel 27 is provided at the bottom of the adjustment seat. Support seats 28 are arranged on both sides of the middle reinforcement plate, and a bracket 29 adapted to the support seat is arranged on the outer side. The bracket structure is used to store each steaming rack on the bracket 29 in the storage state.

[0046] In this embodiment, an adjustment seat 26 and a moving wheel 27 structure are provided, which can enable the steaming rack 11 structure to move on the ground and adjust the height of the filter cover body 19 from the ground when in use.

[0047] Embodiment 4, this embodiment further illustrates the structure of the steam-curing boiler.

[0048] like Fig.11 As shown in , this embodiment uses a curing room and a solar-steam combined heating group. The curing room mainly includes an insulated wall and an internal steam pipe; the solar-steam combined heating group includes a solar heating tube, a steam pipe, a temperature and humidity sensor arranged in the curing room, and a temperature and humidity controller and a solenoid valve arranged outdoors to control the steam temperature, grasp the temperature curve and the relationship between the inlet and outlet of the precast beam and the steam curing efficiency. Solar-steam combined curing can automatically relay heating between solar energy and steam, making better use of solar energy, greatly reducing heating fuel, and effectively reducing the production cost of precast beams.

[0049] The temperature sensor is mainly used to measure the steam temperature in the maintenance shed. When the temperature is lower than the design value, the temperature controller adjusts the combustion volume of the outdoor boiler to make the steam in the pipeline reach the set temperature.

[0050] The embodiments of the present invention described above do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is to achieve all-round curing of prefabricated beams during the curing process through the combination of mobile curing sheds and fixed curing sheds, thereby improving the curing efficiency and curing quality. The design of the internal curing components enables the steam to be evenly distributed inside and outside the prefabricated beams, avoiding the problem of uneven curing.
