Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of prefabricated beam slab, and particularly relates to a beam slab prefabrication integrated production line. BACKGROUND

[0002] In modern bridge engineering construction, the prefabrication quality of T-shaped beam slab as an important load-bearing component directly affects the safety and durability of the bridge. At present, the traditional T-shaped beam slab prefabrication production line has significant defects in the demolding link. After the T-shaped beam slab is poured and shaped, there are both vertical contact surfaces and horizontal contact surfaces between the mold and the T-shaped beam slab. The existing vertical or horizontal demolding methods inevitably cause friction between the mold and the surface of the T-shaped beam slab during the separation process. Such friction not only causes defects such as scratches and cracks on the surface of the concrete, reducing the appearance quality of the T-shaped beam slab, but also may damage the internal structure of the concrete, weakening its bearing capacity. In addition, in order to overcome the frictional resistance, the demolding equipment needs to provide a large power, resulting in increased energy consumption and intensified equipment wear and tear, and at the same time, the demolding efficiency is low, which is difficult to meet the needs of large-scale engineering construction. SUMMARY

[0003] In view of the problems and deficiencies of the prior art, the application provides a beam slab prefabrication integrated production line, which effectively solves the demolding problem of the traditional T-shaped beam slab prefabrication production line through innovative design of the unit structures and functions, and comprehensively improves the prefabrication quality and production efficiency of the T-shaped beam slab.

[0004] The application is implemented through the following technical solutions:

[0005] A beam slab prefabrication integrated production line comprises a steel bar processing unit, a movable mold table, a mold closing mechanism, a concrete pouring unit, a steam curing unit and a finished product transfer unit arranged in sequence along the extension direction of the ground rail.

[0006] The steel bar processing unit processes the steel bars to form a T-shaped steel bar framework. The steel bar processing unit processes the steel bars through specialized processing equipment and process, such as straightening, cutting, bending and welding, to form a T-shaped steel bar framework meeting the design requirements, thereby laying a foundation for the internal structure of the T-shaped beam slab.

[0007] The mobile mold table is one of the core components of the production line, and its structure design is extremely innovative. The mobile mold table includes a mobile platform, a strip-shaped mold table fixed at the center of the mobile platform, two inclined slides located on both sides of the strip-shaped mold table, two oppositely arranged T-shaped mold plates, and two oppositely arranged side mold plates. A transfer groove is formed in the strip-shaped mold table, and the strip-shaped mold table, the T-shaped mold plate, and the side mold plate jointly form a pouring area for accommodating a T-shaped steel reinforcement framework. The side mold plate is slidably connected to the inclined slide through a support frame and can move along the extension direction of the inclined slide from the center of the mobile platform to both sides, and the height of the inclined slide gradually decreases. This design of inclined slide breaks the limitation of traditional vertical or horizontal demolding. When demolding, the side mold plate can slide downward along the inclined slide, eliminating the friction between the mold and the T-shaped beam, effectively avoiding problems such as surface scratches and scratches on the T-shaped beam slab, and improving the appearance quality of the T-shaped beam slab. At the same time, by eliminating the friction, the power demand of the demolding equipment is reduced, the energy consumption and equipment wear are reduced, and the demolding efficiency is improved.

[0008] The mold closing mechanism is fixed on both sides of the ground rail and symmetrically arranged relative to the ground rail, and includes a support steel wall and a hydraulic rod hingedly installed between the support steel wall and the support frame. During mold closing, the hydraulic rod is precisely controlled to extend and retract, pushing the side mold plate to move along the inclined slide until it is tightly combined with the T-shaped mold plate and the strip-shaped mold table to form a closed pouring area. The stable and controllable mold closing power provided by the hydraulic rod can ensure that the mold remains tightly combined and prevent slurry leakage, ensuring the forming precision and quality of the T-shaped beam slab.

[0009] The finished product transfer unit includes a hydraulic support rod installed in the transfer groove, a work-shaped bearing plate fixed to the top of the hydraulic support rod, a transfer trolley, and a traveling crane. When the T-shaped beam slab is poured, the hydraulic support rod is in an extended state, making the surface of the work-shaped bearing plate flush with the surface of the strip-shaped mold table. After the T-shaped beam slab is poured and cured, the hydraulic support rod is retracted, the work-shaped bearing plate is removed, and the transfer trolley is installed at the bottom of the T-shaped beam slab. Subsequently, the lifting rope of the traveling crane is installed into the lifting hole of the transfer trolley, achieving the lifting and transfer of the entire T-shaped beam slab. The unique structure design of the work-shaped bearing plate has higher strength and stability than ordinary bearing plates, and can better support the T-shaped beam slab.

[0010] Further, the oblique sliding seat is in U shape and is provided with two groups of inclined plates at the top, the bottom of the support frame is provided with a sliding plate abutting to the inclined plates, the width of the sliding plate is greater than that of the inclined plate, the sliding plate is further provided with a backing plate and an anti-disengagement plate at both sides, the thickness of the backing plate is greater than that of the inclined plate, the anti-disengagement plate is located at the side of the inclined plate away from the sliding plate, and a fastening bolt penetrates through the sliding plate, the backing plate and the anti-disengagement plate. The structure design greatly enhances the stability and reliability of the connection between the side mold plate and the oblique sliding seat. The width of the sliding plate is greater than that of the inclined plate, which provides a larger contact area, so that the side mold plate is more evenly stressed during movement; the thickness difference between the backing plate and the inclined plate gives a sliding gap. The anti-disengagement plate effectively prevents the sliding plate from disengaging from the inclined plate during movement, ensuring that the demolding process is safe and smooth, and further improving the safety and product quality of production.

[0011] Further, the heads and tails of the sliding plate and the anti-disengagement plate are tilted away from the inclined plate. The tilted structure reduces the direct friction between the sliding plate and the edge of the inclined plate, reduces the degree of wear, prevents small protrusions on the surface of the inclined plate from blocking the sliding of the sliding plate, prolongs the service life of the sliding plate and the oblique sliding seat, and improves the durability and stability of the equipment.

[0012] Further, the two ends of the strip-shaped mold table are provided with steps, the steps are provided with backing blocks through limiting bolts, the height of the backing blocks is flush with the top surface of the strip-shaped mold table, the distance between the side wall of the backing block and the strip-shaped mold table is equal to the thickness of the T-shaped mold plate, the bottom of the T-shaped mold plate has an arc-shaped bottom wall, and the arc-shaped bottom wall is located below the top surface of the strip-shaped mold table, and the top of the T-shaped mold plate is provided with a lifting ring. The structure design realizes the accurate positioning and installation of the T-shaped mold plate on the strip-shaped mold table, the cooperation of the limiting bolt and the backing block ensures the accuracy of the installation position of the T-shaped mold plate, and guarantees the dimensional accuracy of the pouring area; the arc-shaped bottom wall design of the bottom of the T-shaped mold plate makes it easier to install the T-shaped mold plate to the area between the side wall of the backing block and the strip-shaped mold table. The setting of the lifting ring facilitates the lifting and dismounting of the T-shaped mold plate, improves the work efficiency of mold installation and replacement, and reduces the manual operation time and labor intensity.

[0013] Further, the side walls of the two side mold plates are provided with connecting plates aligned with each other, the connecting plates are provided with U-shaped grooves, and a limiting pull rod is installed between the two connecting plates. The limiting pull rod can prevent the side mold plate from moving away from the pouring area. A hydraulic jack is also installed on the moving platform, located directly below the support frame. The limiting pull rod is inserted into the U-shaped groove of the connecting plate, which plays a horizontal limiting role on the side mold plate, effectively preventing the side mold plate from moving outward during the concrete pouring process due to the side pressure of the concrete, ensuring the stability of the shape and size of the pouring area; the hydraulic jack provides vertical support force for the side mold plate. According to the pressure changes at different stages of the concrete pouring process, the support force of the side mold plate can be adjusted in real time through the hydraulic jack, ensuring the stability of the side mold plate during the pouring process, thereby ensuring the forming quality of the T-shaped beam plate.

[0014] Further, the inner side of the side formwork is also provided with a limiting groove, and a limiting plate is inserted and installed in the limiting groove. The limiting plate is located outside the pouring area and abuts against the T-shaped formwork. The limiting plate further limits the position of the T-shaped formwork. During the concrete pouring process, the limiting plate can ensure that the T-shaped formwork maintains an accurate position, prevents the T-shaped formwork from being slightly displaced, and ensures the shape and size accuracy of the pouring area. At the same time, the limiting plate abuts against the T-shaped formwork, which provides a better positioning reference for the T-shaped steel reinforcement framework, helps to improve the installation accuracy of the T-shaped steel reinforcement framework in the pouring area, and further improves the overall quality of the T-shaped beam slab.

[0015] Further, a demolding vibrator is also installed on the side formwork. The demolding vibrator can apply vibration to the side formwork to assist in separating the T-shaped beam slab from the side formwork. During the demolding process, the vibration generated by the demolding vibrator can effectively reduce the adsorption force and friction force between the T-shaped beam slab and the side formwork, and reduce the demolding resistance. Especially for some cases where the concrete is tightly bonded to the side formwork, the vibration of the demolding vibrator can make the T-shaped beam slab and the side formwork more easily separated, making the demolding process smoother, greatly improving the demolding efficiency, shortening the production cycle, and also reducing the risk of damage to the T-shaped beam slab due to difficult demolding.

[0016] Further, the production line also includes a central control system, which is in control connection with the steel bar processing unit, the movable formwork table, the formwork closing mechanism, the concrete pouring unit, the steam curing unit, and the finished product transfer unit. The central control system uses advanced automatic control technology and algorithms to realize real-time monitoring and accurate control of each unit of the entire production line. By presetting production parameters and process flow, the central control system can automatically coordinate the operation of each unit, such as accurately controlling the steel bar processing parameters of the steel bar processing unit, the moving path and speed of the movable formwork table, the form closing force and time of the formwork closing mechanism, the pouring speed and volume of the concrete pouring unit, the curing temperature and time of the steam curing unit, and the transfer sequence of the finished product transfer unit, etc. This not only improves the degree of automation of production, reduces manual intervention, and reduces the probability of human operation errors, but also allows timely adjustment of the operating parameters of each unit according to the actual situation during the production process, optimizes the production process, and improves the production efficiency. At the same time, it is convenient for production management personnel to monitor and manage the entire production process, realizes the informatization and intelligentization of the production process.

[0017] Further, the concrete pouring unit includes a torpedo tank for storing and transporting concrete and a distributing machine capable of uniformly pouring concrete into the pouring area. This combination realizes efficient transportation and accurate pouring of concrete. The large storage and transportation capacity of the torpedo tank ensures continuous supply of concrete. The distributing machine can flexibly adjust the distribution method and speed according to the shape and size of the pouring area, ensuring the uniformity and compactness of concrete pouring, avoiding pouring defects such as honeycomb and pitted surface, and ensuring the pouring quality of the T-shaped beam slab. The steam curing unit can perform primary mold curing and secondary demolding curing on the T-shaped beam slab. The primary mold curing can provide a suitable temperature and humidity environment for the T-shaped beam slab after pouring, accelerate the early strength growth of the concrete, and improve the setting quality of the concrete. The secondary demolding curing further cures the T-shaped beam slab after demolding to ensure that the strength and performance of the T-shaped beam slab meet the design requirements. This double curing method can provide targeted curing conditions according to the needs of the T-shaped beam slab at different stages, effectively shortening the curing time of the T-shaped beam slab, improving the production efficiency, and ensuring the quality stability of the T-shaped beam slab.

[0018] Further, the transfer trolley can move to the transfer tank. The bottom of the transfer trolley is provided with steel wheels. The length of the transfer trolley is greater than the width of the abutting part of the T-shaped beam slab to the transfer trolley, and the part of the transfer trolley protruding from the T-shaped beam slab is provided with a lifting hole. The steel wheels at the bottom of the transfer trolley can move flexibly on the ground, facilitating the movement of the T-shaped beam slab. The length of the transfer trolley is greater than the width of the abutting part of the T-shaped beam slab, and the lifting hole is provided in the part protruding from the T-shaped beam slab, so that the transfer trolley can stably carry the T-shaped beam slab and be conveniently lifted by the traveling crane. During lifting, the lifting hole can accurately hook the lifting hook of the traveling crane, ensuring the safety and reliability of the lifting process, improving the flexibility and efficiency of the T-shaped beam slab transfer, and facilitating the transfer of the T-shaped beam slab to different storage areas or subsequent processing positions.

[0019] The beneficial effects of the present application are:

[0020] The beam slab prefabrication integrated production line of the present application realizes a technological breakthrough in the field of T-shaped beam slab prefabrication through systematic innovation design and multi-unit collaborative work. Its overall beneficial effects are reflected in multiple key aspects, which can effectively solve the drawbacks of traditional production lines and bring significant value to bridge engineering construction.

[0021] Quality improvement: From the forming source of T-beam slab to the final product, the production line guarantees the product quality in all aspects. In the steel bar processing unit, specialized equipment and precise process ensure the accurate size and stable structure of T-shaped steel skeleton, providing reliable internal support for T-beam slab. The design of mobile mold table is particularly critical. The oblique sliding seat cooperates with the oblique demolding mode of the side mold plate, greatly reducing the friction between the mold and the T-beam slab, avoiding the damage and scratches on the concrete surface caused by friction, making the T-beam slab surface smooth and improving the appearance quality. At the same time, the reduced friction force avoids the damage of the internal structure of the concrete due to demolding, ensuring that the bearing capacity is not affected. The primary mold curing and secondary demolding curing double mechanism of the steam curing unit provides precise curing according to the different needs of T-beam slab at different stages, accelerates the growth of concrete strength, improves the coagulation quality of concrete, and ensures that the strength and performance of T-beam slab meet the design requirements, thus guaranteeing the overall quality of T-beam slab from multiple aspects.

[0022] Efficiency improvement: The efficient cooperation and innovative design of each unit of the production line significantly improve the production efficiency. The automatic processing equipment of the steel bar processing unit can quickly complete the straightening, cutting, bending, and welding of steel bars, greatly shortening the production time of steel skeleton compared to traditional manual processing. The mobile mold table moves quickly between units, reducing the waiting time for process connection. Its unique demolding design reduces the demolding resistance and cooperates with the demolding vibrator to make the demolding process smoother, effectively shortening the demolding time. The hydraulic drive of the mold closing mechanism makes the operation simple and fast, and can quickly complete the assembly of the mold. The combination of the torpedo tank and the distributor in the concrete pouring unit realizes efficient transportation and uniform pouring of concrete, avoiding downtime and rework caused by insufficient concrete supply or uneven pouring. The steam curing unit adjusts the curing parameters automatically according to the strength growth data of T-beam slab through the intelligent temperature control system, shortens the curing period under the premise of ensuring quality. The combination of the transfer car and the gantry crane in the finished product transfer unit can quickly and efficiently transfer T-beam slab to the designated location, reducing the waiting time for finished product accumulation. The real-time monitoring and automatic coordination of the central control system to the entire production line enables close cooperation between units, realizes seamless connection of the production process, further improves the overall production efficiency, and meets the rapid production demand of T-beam slab for large-scale engineering construction.

[0023] Cost control: The production line realizes effective control of cost through various ways. In terms of energy consumption, due to the reduction of frictional resistance in the demolding process, the power required by the demolding equipment is greatly reduced, thereby reducing the power consumption; at the same time, the efficient operation and reasonable scheduling of each unit equipment avoid the waste of energy and reduce the production energy consumption cost. In terms of equipment maintenance, the reduced friction and stable operation of the equipment reduce the degree of equipment wear and tear, prolong the service life of the equipment, reduce the frequency of equipment repair and replacement, and reduce the equipment maintenance cost. In addition, the automation and intelligence level of the production line is improved, reducing the manual operation link and reducing the labor cost; at the same time, precise production control reduces the waste of raw materials, further reduces the production cost, and improves the economic benefit of the enterprise.

[0024] Intelligent management: The introduction of the central control system enables the production line to realize highly informationized and intelligent management. By presetting the production parameters and process flow, the system can automatically coordinate the operation of each unit without frequent manual intervention, reducing the probability of human operation errors and improving the stability and reliability of the production process.

[0025] Adaptability and flexibility: The production line has good adaptability and flexibility, which can meet the prefabrication needs of different projects and different specifications of T-shaped beam plates. In the steel bar processing unit, the specifications and processing technology of the steel bars can be flexibly adjusted according to the design requirements of the T-shaped beam plate; the T-shaped beam plate of the mobile mold table and the side mold plate can be replaced according to the size of the T-shaped beam plate, and the pouring area size can be accurately adjusted by adjusting the limiting bolts, pads and limiting plates and other components; the concrete pouring unit can adjust the operating parameters of the torpedo tank and the distributor according to the characteristics of the concrete and the pouring requirements; the steam curing unit can automatically adjust the curing parameters according to different environmental conditions and strength requirements of the T-shaped beam plate.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0040] It should be noted that the left, right, up, down, front, back and other orientation terms in the embodiments of the present application are only relative concepts or are with reference to the normal use state of the product, i.e. the direction of movement of the product, and should not be considered as having a limiting nature.

[0041] In addition, it should be noted that the "relative motion" and other dynamic terms mentioned in the embodiments of the present application not only include positional changes, but also include motions that do not have relative changes in position but have changes in state, such as rotation and rolling.

[0042] Finally, it should be noted that when a component is referred to as "located" or "disposed" on another component, it can be on the other component or can have a centering component present at the same time. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or can have a centering component present at the same time.

[0043] In the prior art, the mold and the concrete member have vertical and horizontal double contact surfaces during the T-beam slab prefabrication process, and the traditional demolding method causes friction damage when the mold is separated. This friction not only causes scratches on the surface of the concrete, but also can damage the internal structure, and at the same time requires high-power equipment to drive, resulting in high energy consumption and low efficiency.

[0044] To solve the above problems, the present application changes the separation path of the mold and the member (T-beam slab) to reduce the contact area between the mold and the member (T-beam slab) during separation. By analyzing the friction mechanics model, a solution of changing the motion trajectory of the mold is proposed. Based on the modular production concept, an integrated production line layout is designed to connect the mold motion mechanism and the concrete curing process, forming a continuous operation process.

[0045] Therefore, the present application proposes a beam slab prefabrication integrated production line as shown in Figures 1 to 11 The beam slab prefabrication integrated production line includes a steel bar processing unit 02, a movable mold table 03, a mold closing mechanism 04, a concrete pouring unit 05, a steam curing unit 06 and a finished product transfer unit 07 arranged in sequence along the extension direction of the ground rail 01. The steel bar processing unit 02 processes to form a T-shaped steel reinforcement skeleton 9. The movable mold table 03 includes a movable platform 1, a strip-shaped mold table 2 with a transfer groove 21, inclined sliding seats 3 located on both sides of the strip-shaped mold table 2, two oppositely arranged T-shaped mold plates 4 and two oppositely arranged side mold plates 5. The mold closing mechanism 04 is connected to the support frame 51 of the side mold plate 5 through the support steel wall 6 and the hydraulic rod 61 to realize mold closing and demolding. The finished product transfer unit 07 is configured with a hydraulic support rod 23, a work-shaped bearing plate 24, a transfer trolley 7 and a traveling crane.

[0046] The inclined sliding seat 3 refers to a guide device with a height decreasing feature, which can be realized by welding an inclined rail with a U-shaped steel component. The height change causes the side mold plate 5 to produce an inclined displacement trajectory. The strip-shaped mold table 2 refers to a basic platform for carrying out pouring operations, which can be realized by welding a box-shaped structure with a steel plate. The transfer groove 21 inside allows the transfer of finished component T-shaped beam plates.

[0047] Specifically, the skeleton prepared by the steel bar processing unit 02 is positioned on the surface of the strip-shaped mold table 2, the T-shaped mold plate 4 is installed, and the two side mold plates 5 are moved along the inclined sliding seat 3 to form a closed pouring space. After the concrete hardens, the hydraulic rod 61 drives the support frame 51 to move outward along the inclined sliding seat 3, causing the side mold plate 5 to produce an inclined separation path with the T-shaped beam plate. The hydraulic support rod 23 at the bottom of the T-shaped beam plate is lowered, replacing the work-type carrying plate 24 with the transfer trolley 7, and the overhead crane lifts the transfer trolley 7 to lift the T-shaped beam plate, thereby transferring the T-shaped beam plate to the storage area. The entire process reduces the contact friction between the side mold plate 5 and the T-shaped beam plate through the inclined separation mechanism.

[0048] Compared with the prior art, the traditional demolding device can only realize vertical or horizontal single direction movement. The present scheme forms a composite motion trajectory through the inclined sliding seat 3, so that the separation direction of the side mold plate 5 forms an angle with the surface of the T-shaped beam plate. The conventional production line has dispersedly arranged devices for each process. The present scheme forms a flow line operation mode through the ground rail 01 in series. The existing transfer equipment needs additional lifting devices. The present scheme uses the built-in transfer groove 21 in the strip-shaped mold table 2 to realize the translation of the T-shaped beam plate.

[0049] Through the above technical scheme, the present application effectively avoids the direct friction between the side mold plate 5 and the concrete surface of the T-shaped beam plate during the demolding process, and maintains the integrity of the component surface. The inclined separation mechanism reduces the demolding resistance, reduces the energy consumption of the equipment, and prolongs the service life of the parts. The integrated layout shortens the process transfer time and improves the production line operation efficiency. The built-in transfer system realizes the damage-free transfer of the finished product, avoiding the risk of structural damage caused by secondary lifting.

[0050] The process flow of the device is as follows:

[0051] 1. The steel bar processing unit 02 processes the steel bars to form a T-shaped steel skeleton 9, and the T-shaped steel skeleton 9 is lifted to the pouring area 11 above the movable mold table 03 by the overhead crane.

[0052] 2. The spacer block 26 is installed on the step 25 of the strip-shaped mold table 2 through the limiting bolt, and the T-shaped mold plate 4 is lifted by the overhead crane, so that the arc-shaped bottom wall 41 of the T-shaped mold plate 4 is clamped into the area between the side wall of the spacer block 26 and the strip-shaped mold table 2, realizing the preliminary fixation of the T-shaped mold plate 4.

[0053] 3, the hydraulic rod 61 of the closing mechanism 04 is hinged and installed between the support frame 51 and the support steel wall 6, the hydraulic rod 61 is elongated, the support frame 51 and the side formwork 5 move towards the direction close to the strip formwork 2, until the two side formworks 5 extrude the T-shaped formwork 4 to form the pouring area 11 (the two side formworks 5 extruding the T-shaped formwork 4 can form clamping positioning to the T-shaped formwork 4).

[0054] 4, the limiting plate 58 is inserted into the limiting groove 57 to prevent the position deviation of the T-shaped formwork 4 above during pouring; the limiting pull rod 56 is installed between the connecting plates 55 of the two side formworks 5.

[0057] 7, the limiting pull rod 56 is removed, and the demolding vibrator 8 is started to separate the two side formworks 5 from the T-shaped beam slab (since the side formwork 5 is slidingly connected with the inclined sliding seat 3, a very small force can move the side formwork 5); if the side formwork 5 cannot be manually or simply instrumentally moved, the movable formwork 03 can also be moved to the closing mechanism 04, the hydraulic rod 61 is installed to the support frame 51, and the hydraulic rod 61 is contracted to separate the side formwork 5 from the T-shaped beam slab;

[0058] 8, the cushion 26 installed on the step 25 of the strip formwork 2 is removed, and the row hoist is used to tilt and lift the T-shaped formwork 4 (it should be noted that since the side of the T-shaped formwork 4 away from the T-shaped beam slab has no limiting structure, when lifting the T-shaped formwork 4, the T-shaped formwork 4 should be tilted and lifted to avoid the vertical lifting which causes the wear of the T-shaped formwork 4 and the T-shaped beam slab).

[0059] 9, the movable formwork 03 drives the T-shaped beam slab into the steam curing unit 06 for demolding and curing;

[0061] The application further proposes that the inclined sliding seat 3 is in U-shaped and provided with two groups of inclined plates 31 at the top, the bottom of the support frame 51 is provided with a sliding plate 52 abutting to the inclined plates 31, the width of the sliding plate 52 is greater than the width of the inclined plate 31, the two sides of the sliding plate 52 are further provided with the cushion 26 and the anti-disengagement plate 54, the thickness of the cushion 26 is greater than the thickness of the inclined plate 31, the anti-disengagement plate 54 is located at the side of the inclined plate 31 away from the sliding plate 52, and the fastening bolt penetrates and fixes the sliding plate 52, the cushion 26 and the anti-disengagement plate 54.

[0062] Wherein, the oblique slide 3 is U-shaped refers to the oblique slide 3 is arranged in the moving die table 03 in U-shaped, the oblique slide 3 can be specifically formed by bending steel plate, form the structure of two side vertical plate and upper and lower flat plate, for supporting the slide plate 52.Oblique plate 31 refers to the inclined guide plate, can be specifically fixed on the top of U-shaped slide by welding, form two inclined tracks, for guiding the slide plate 52 along the preset angle sliding.The width of the slide plate 52 is greater than the width of the oblique plate 31 refers to the horizontal dimension of the slide plate 52 beyond the edge of the oblique plate 31, can be specifically processed by rectangular steel plate, so that the slide plate 52 covers the oblique plate 31 on both sides, to avoid the misplacement between the slide plate 52 and the oblique plate 31.The thickness of the cushion block 26 is greater than the thickness of the oblique plate 31 refers to the vertical dimension of the cushion block 26 exceeds the thickness of the oblique plate 31, can be specifically processed by metal block, so that the gap is formed between the cushion block 26 and the slide plate 52, give the slide plate 52 relative to the sliding space of the oblique plate 31.The anti-drop plate 54 is located outside the oblique plate 31 refers to the plate structure is arranged on the side of the oblique plate 31 away from the slide plate 52, can be specifically fixed by welding angle steel or steel plate, for blocking the slide plate 52 from the edge of the oblique plate 31 out.The fastening bolt penetrates the slide plate 52, the cushion block 26 and the anti-drop plate 54 refers to the bolt through the three and lock, can be specifically used high strength bolt with nut, form rigid connection, prevent the slide plate 52 from deviating in the process of sliding.

[0063] Specifically, the slide plate 52 is in contact with the surface of the oblique plate 31 through the bottom plane, and moves in the inclined direction under the guidance of the oblique slide 3.The design that the width of the slide plate 52 exceeds the edge of the oblique plate 31 makes the slide plate 52 cover the oblique plate 31 all the time in the moving process, avoiding the local stress concentration caused by insufficient contact area.The cushion block 26 is installed on both sides of the slide plate 52, and its thickness is greater than that of the oblique plate 31, forming a gap between the oblique plate 31 and the anti-drop plate 54, reducing the sliding friction resistance between the oblique plate 31 and the anti-drop plate 54.The anti-drop plate 54 is fixed with the slide plate 52 and the cushion block 26 by bolts, forming a constraint structure surrounding the edge of the oblique plate 31, preventing the slide plate 52 from separating from the oblique plate 31 under vibration or impact.The fastening bolt rigidly connects the three, ensuring that the slide plate 52 maintains a stable posture during movement.

[0064] Compared with the prior art, the slide plate 52 in the traditional stripping mechanism often moves in the vertical plane, and it is difficult to strip due to the large adhesion between the T-shaped beam plate and the side mold plate 5.However, in the present device, the side mold plate 5 has a force to slide downward along the oblique plate 31 under its own gravity, so the power requirement of the stripping equipment is low.The combination design of the cushion block 26 and the anti-drop plate 54 forms multiple limiting, effectively preventing the slide plate 52 from dislocation or deviation, and improving the stability of the stripping process.

[0065] By the technical scheme, the present application solves the problem that the existing stripping equipment has high stripping power requirement for the side mold plate 5 and stripping is difficult, reduces contact friction through oblique sliding and gap control, avoids the deflection of the sliding plate 52 through the anti-stripping structure, ensures the stability of the separation of the mold and the concrete component during the stripping process, and reduces the equipment wear risk.

[0066] The present application further proposes that the plate head and the plate tail of the sliding plate 52 and the anti-stripping plate 54 are both tilted towards the direction away from the inclined plate 31.

[0067] The sliding plate 52 refers to a plate-shaped component that is in contact with the surface of the inclined plate 31, which can be formed by stamping a steel plate, and the two ends are bent upwards to form a tilted structure, and the tilt angle can be 5-15 degrees, which reduces the sliding resistance by reducing the contact area between the sliding plate 52 and the inclined plate 31. The anti-stripping plate 54 refers to a limiting component installed on both sides of the sliding plate 52, which can be fixed by welding a steel plate, and the end is bent upwards to form a tilted structure, and the tilt height can be 10-20 mm, and the tilted edges are provided on both sides of the sliding plate 52 and the anti-stripping plate 54 to make the sliding plate 52 and the anti-stripping plate 54 more smooth when sliding along the inclined plate 31.

[0068] Specifically, the tilted end of the sliding plate 52 and the anti-stripping plate 54 forms a guide slope during movement, and when the side mold plate 5 moves along the inclined sliding seat 3, the tilted structure can avoid hard collision between the sliding plate 52 and the surface protrusions of the inclined plate 31, and reduce the friction area of the contact surface between the sliding plate 52 and the inclined plate 31. When the sliding plate 52 moves to the end of the inclined plate 31, the tilted end can guide the sliding plate 52 to naturally transition along the slope of the inclined plate 31, preventing hard collision of the sliding plate 52.

[0069] Compared with the prior art, the traditional sliding plate 52 adopts a flat plate structure, which is prone to poor movement due to excessive contact surface friction during oblique sliding, and the end of the sliding plate 52 is prone to collision with the edge of the inclined plate 31, which can produce metal debris to pollute the pouring area 11.

[0070] Through the above technical scheme, the present application solves the problem of jamming of the sliding plate 52 caused by friction resistance during oblique movement, ensures the smooth movement of the side mold plate 5 along the inclined sliding seat 3, avoids the position deviation of the side mold plate 5 caused by the jamming of the sliding plate 52, and improves the forming precision and stripping efficiency of the T-shaped beam plate.

[0071] The present application further proposes that the two ends of the strip-shaped mold table 2 are provided with steps 25, the steps 25 are provided with pad blocks 26 through limiting bolts, the height of the pad blocks 26 is flush with the top surface of the strip-shaped mold table 2, the distance between the side wall of the pad block 26 and the strip-shaped mold table 2 is equal to the thickness of the T-shaped mold plate 4, the bottom wall of the T-shaped mold plate 4 is arc-shaped and located below the top surface of the strip-shaped mold table 2, and the top of the T-shaped mold plate 4 is provided with a lifting ring 42.

[0072] The step 25 refers to a recess structure arranged at the end of the strip-shaped mold table 2, which can be formed by welding or casting, and is used to provide a mounting reference surface for the pad 26 and fix the pad 26. The limiting bolt refers to a fastener penetrating through the pad 26 and the step 25, which can be implemented by a high-strength bolt, and is used to fix the pad 26 on the step 25 to prevent the pad 26 from moving during pouring. The pad 26 refers to a supporting block mounted on the step 25, which can be made of steel plate or cast iron, and the spacing between the side wall of the pad 26 and the strip-shaped mold table 2 is designed to be equal to the thickness of the T-shaped template 4, which is used to limit and fix the bottom of the T-shaped template 4. The arc-shaped bottom wall 41 refers to a curved transition structure at the bottom of the T-shaped template 4, which can be processed by a numerical control machine. The arc-shaped bottom wall 41 can make the T-shaped template 4 more smoothly enter the limiting area between the pad 26 and the strip-shaped mold table 2, and when demolding, the T-shaped template 4 can be rotated around the center line of the arc-shaped bottom wall 41, avoiding the plane friction between the T-shaped template 4 and the T-shaped beam plate during demolding operation, and reducing the quality of the T-shaped beam plate. The lifting ring 42 refers to a ring-shaped member mounted on the top of the T-shaped template 4, which can be fixed by welding or bolt connection, and is used to vertically lift the T-shaped template 4 by hoisting equipment.

[0073] Specifically, after the steps 25 are arranged at both ends of the strip-shaped mold table 2, the pad 26 is fixed on the step 25 by the limiting bolt, and the top surface of the pad 26 is flush with the top surface of the strip-shaped mold table 2, ensuring that the T-shaped template 4 forms stable contact between the bottom wall and the strip-shaped mold table 2 when installed. When the T-shaped template 4 is placed between the side wall of the pad 26 and the strip-shaped mold table 2, its thickness matches the spacing between the two, achieving accurate positioning. When demolding, the pad 26 is first removed, the arc-shaped bottom wall 41 of the T-shaped template abuts against the side surface of the strip-shaped mold table 2 and does not abut against the T-shaped beam plate, and the T-shaped template 4 is lifted obliquely by the row hoist, that is, the T-shaped template 4 first rotates around the center line of the arc-shaped bottom wall 41 to separate from the T-shaped beam plate, and then is hoisted to the storage area by the row hoist.

[0074] Compared with the prior art, the T-shaped template 4 in the existing production line is usually directly placed on the flat mold table surface, and when demolding, the template and the concrete produce large frictional resistance due to horizontal contact. The present scheme changes the contact surface form by the arc-shaped bottom wall 41 structure, so that the T-shaped template 4 first tilts to separate from the concrete surface of the T-shaped beam plate, and then is lifted and moved away from the movable mold table 03 under the action of the row hoist.

[0075] Through the above technical scheme, the damage problem caused by the friction between the T-shaped template 4 and the concrete surface during demolding is effectively solved. By rotating the arc-shaped bottom wall 41 by a certain angle and combining with the inclined lifting method, the frictionless separation is realized, and the positioning accuracy of the T-shaped template 4 is improved by the cooperation of the pad 26 and the limiting bolt, avoiding secondary friction caused by mispositioning, so as to ensure the appearance quality and structural strength of the T-shaped beam plate.

[0076] The side walls of the two side formwork plates 5 are provided with connecting plates 55 aligned with each other, U-shaped grooves 551 are formed in the connecting plates 55, and limiting pull rods 56 are installed between the two connecting plates 55, the limiting pull rods 56 can prevent the side formwork plates 5 from moving away from the pouring area 11, and a hydraulic jack 12 is also installed on the moving platform 1 and located directly below the support frame 51.

[0077] The connecting plate 55 refers to a plate-shaped structure fixed to the side wall of the side formwork plate 5, which can be achieved by welding or bolt connection, and is used to provide an installation position for the limiting pull rod 56. The U-shaped groove 551 refers to a groove structure formed in the connecting plate 55, which can be formed by machining, and is used to accommodate the limiting pull rod 56 and limit its displacement direction. The limiting pull rod 56 refers to a rigid rod that spans the two connecting plates 55, which can be made of threaded steel or alloy steel, and achieves lateral limiting of the side formwork plate 5 by being inserted into the U-shaped groove 551. The hydraulic jack 12 refers to a hydraulic support device installed on the moving platform 1, which can be achieved by a double-acting hydraulic cylinder structure, and is used to provide a vertical force below the support frame 51.

[0078] Specifically, after the mold is closed, the limiting pull rod 56 is inserted into the U-shaped groove 551 of the two connecting plates 55, the length of the pull rod is adjusted to keep the two side formwork plates 5 at a predetermined distance, and prevent them from shifting outward. When pouring concrete, the side formwork plates 5 may be displaced due to fluid pressure, and the rigid constraint of the limiting pull rod 56 can effectively counteract this force. The hydraulic jack 12 is located directly below the support frame 51 and can apply a jacking force during the concrete setting stage to compensate for the sinking deformation of the support frame 51 due to the load, thereby maintaining the geometric accuracy of the formwork system. During the demolding stage, the hydraulic jack 12 can adjust the support height to cooperate with the formwork separation action.

[0079] Compared with the prior art, in the traditional demolding process, the side formwork plates 5 only rely on their own stiffness to resist the side pressure of the concrete, which is prone to deformation and displacement, resulting in friction between the formwork and the beam surface. The present scheme forms a rigid restraint system through the limiting pull rod 56, and cooperates with the dynamic support of the hydraulic jack 12, which not only ensures the positioning accuracy of the side formwork plates 5, but also avoids the stress concentration problem caused by rigid restraint.

[0080] Through the above technical scheme, the displacement of the side formwork plates 5 during the pouring and curing stages is effectively controlled, the contact friction between the formwork and the concrete surface during the demolding process is avoided, surface scratches and internal structure damage are avoided, and at the same time, the adjustable hydraulic support system adapts to the load changes under different working conditions, thereby improving the stability and service life of the formwork system.

[0081] The inner side of the side formwork 5 is provided with a limiting groove 57, and the limiting groove 57 is inserted and connected with a limiting plate 58. The limiting plate 58 is located outside the pouring area 11 and abuts against the T-shaped formwork 4.

[0082] The limiting groove 57 is a groove structure formed on the inner side of the side formwork 5 and can be formed by mechanical milling or casting process. The limiting plate 58 is a metal plate matched with the limiting groove 57 and can be formed by cutting a steel plate. The limiting plate 58 is inserted into the limiting groove 57 to form a mechanical constraint and is used to limit the lateral displacement of the T-shaped formwork 4 during pouring.

[0083] Specifically, during the closing stage, the limiting plate 58 is inserted into the limiting groove 57 of the side formwork 5, and the end of the limiting plate 58 abuts against the side wall of the T-shaped formwork 4. When the concrete is poured, the T-shaped formwork 4 is subjected to lateral pressure of the concrete, and the limiting plate 58 prevents the T-shaped formwork 4 from moving outward by rigid abutment, thereby maintaining the geometric accuracy of the formwork system. During the demolding stage, the insertion structure of the limiting plate 58 and the limiting groove 57 allows the side formwork 5 to be separated in the vertical direction, thereby avoiding the sliding friction between the formwork and the concrete surface during the traditional demolding process.

[0084] Compared with the prior art, the traditional demolding method relies on the direct contact constraint between the formwork and the concrete, and the sliding friction during demolding causes surface damage. The present application provides rigid positioning during the pouring stage and converts into a friction-free vertical separation path during the demolding stage by the insertion constraint of the limiting groove 57 and the limiting plate 58, thereby fundamentally eliminating the relative sliding between the contact surface of the formwork and the concrete.

[0085] Through the above technical scheme, the present application effectively avoids the frictional damage between the T-shaped formwork 4 and the concrete surface of the T-shaped beam plate during the demolding process, ensures the surface integrity and dimensional accuracy of the T-shaped beam plate, reduces the demand for equipment thrust during demolding operation, prolongs the service life of the T-shaped formwork 4 and improves the demolding efficiency.

[0086] The side formwork 5 is further provided with a demolding vibrator 8, and the demolding vibrator 8 can apply vibration to the side formwork 5 to assist the separation of the T-shaped beam plate and the side formwork 5.

[0087] The demolding vibrator 8 is a mechanical vibration device installed on the side formwork 5 and can be an electric eccentric vibrator or a pneumatic high-frequency vibrator. The vibration energy is transmitted to the contact interface between the concrete and the side formwork 5 through the side formwork 5 to destroy the adhesion between them. The vibration application direction is the direction of the exciting force generated by the vibrator and can be perpendicular to the inner wall of the side formwork 5 or form an angle with the demolding direction. The separation speed of the side formwork 5 and the concrete can be controlled by adjusting the vibration frequency and amplitude.

[0088] Specifically, the demolding vibrator 8 is started in the demolding stage, and the vibration energy is transmitted to the concrete contact surface through the side mold plate 5, so that high-frequency micro-amplitude vibration is generated between the concrete surface layer and the side mold plate 5, a micro gap is formed to reduce the frictional resistance of the contact surface. During the vibration process, the adhesion between the side mold plate 5 and the T-beam plate is gradually destroyed, and when the side mold plate 5 moves along the inclined sliding seat 3, only the residual friction needs to be overcome, avoiding the damage to the concrete surface caused by traditional hard pulling. For example, when the hydraulic rod 61 drives the support frame 51 to move outward, the vibrator is started synchronously and continues until the side mold plate 5 is completely separated from the surface of the T-beam plate.

[0089] Compared with the prior art, the traditional demolding operation relies on the hydraulic mechanism to forcibly separate the mold plate and the concrete, and the contact surface friction causes surface scratches and structural damage. The vibration-assisted demolding makes the side mold plate 5 and the concrete controllably separate by reducing the interfacial adhesion, and the contact surface friction is effectively weakened by the vibration energy. The prior art does not use vibration demolding means, and cannot dynamically adjust the interfacial friction state during the mold plate movement.

[0090] Through the above technical scheme, the present application solves the problem of surface damage caused by hard friction between the side mold plate 5 and the concrete during demolding. The vibration energy makes the contact surface between the side mold plate 5 and the T-beam plate controllably separate, reduces the demolding resistance, maintains the integrity of the concrete surface, reduces the power load of the demolding equipment, and prolongs the service life of the hydraulic elements.

[0091] The present application further proposes that the production line further comprises a central control system, and the central control system is in control connection with the reinforcing steel bar processing unit 02, the movable mold table 03, the mold closing mechanism 04, the concrete pouring unit 05, the steam curing unit 06 and the finished product transfer unit 07 respectively.

[0092] The central control system refers to an integrated control platform, which can be realized by a programmable logic controller or an industrial computer, and data interaction links are established with each unit through a communication protocol to realize automatic scheduling and real-time monitoring of the production process. The control connection refers to the relationship between signal transmission and instruction execution, which can be realized by a wired or wireless communication module, for example, the control instructions are transmitted through Ethernet, RS485 bus or wireless radio frequency technology, so that the central control system can synchronize and coordinate the action timing of each unit.

[0093] Specifically, the central control system controls the skeleton forming parameters of the steel bar processing unit 02, the positioning accuracy of the movable mold table 03, the stroke of the hydraulic rod 61 of the mold closing mechanism 04, the distribution speed of the concrete pouring unit 05, the temperature and humidity curve of the steam curing unit 06, and the transfer path of the finished product transfer unit 07 through a preset program. For example, when the movable mold table 03 enters the mold closing station, the central control system synchronously triggers the extension action of the hydraulic rod 61 to ensure that the side mold plate 5 and the T-shaped mold plate 4 are accurately closed; during the steam curing stage, the system automatically switches the primary mold curing and secondary demolding curing modes according to the preset time to avoid temperature control deviation caused by manual operation.

[0094] Compared with the prior art, the traditional production line relies on manual segmented operation, and the coordination between units is poor, which is prone to process connection delay or parameter matching error. The global scheduling of the central control system eliminates the problem of asynchronous action caused by human intervention, such as automatically coordinating the start and stop of the demolding vibrator 8 and the lifting action of the hydraulic support rod 23 during the demolding stage, to avoid damage to the concrete surface caused by the timing error of the operation.

[0095] Through the above technical solutions, the present application realizes full-automatic closed-loop control of the production process, reduces the damage to the mold friction and the concrete structure caused by human operation errors, and improves the coordination efficiency of each unit to ensure the consistency of the T-shaped beam plate forming quality and the production rhythm.

[0096] The present application further proposes that the concrete pouring unit 05 comprises a torpedo tank and a distributor; and the steam curing unit 06 can perform primary mold curing and secondary demolding curing on the T-shaped beam plate.

[0097] The torpedo tank refers to a sealed container for transporting ready-mixed concrete, which can be implemented by a metal tank body with a rotating discharge port, and its sealing structure can prevent concrete segregation. The distributor refers to a device for uniformly spreading concrete to the mold, which can be implemented by a movable mechanical arm with a screw conveyor to realize continuous filling of the pouring area 11 through reciprocating motion. The primary mold curing refers to steam curing under the condition that the mold is closed after the concrete has initially set, and the temperature and humidity are maintained in the closed space; the secondary demolding curing refers to supplementary curing on the surface of the exposed T-shaped beam plate after the side mold plate 5 and the T-shaped mold plate 4 are removed, which can be implemented by a segmented steam nozzle covering the beam surface.

[0098] Specifically, the torpedo tank is transported to above the distributing machine through the track, the concrete is dropped into the receiving hopper of the distributing machine through the rotating discharge port, and the spiral conveyor uniformly spreads the concrete along the length direction of the strip-shaped mold table 2. In the initial mold maintaining stage, steam is input into the closed pouring area 11 through the pipe at the bottom of the mold table, so that the concrete completes the preliminary strength growth in the constant temperature and humidity environment; in the secondary demolding maintaining stage, steam is sprayed from the adjustable nozzles at the top and side of the T-shaped beam plate, and the exposed surface after demolding is subjected to directional humidification.

[0099] In some specific embodiments, the capacity of the torpedo tank can be 8-12 cubic meters, the conveying speed of the distributing machine can be adjusted to 0.5-1.2 meters per minute. The temperature control range of the steam curing unit 06 can be set to 40-60℃, the initial curing duration can be 6-8 hours, and the secondary curing duration can be 4-6 hours.

[0100] Through the above technical solution, the present application effectively avoids the adhesion damage of the concrete surface of the T-shaped beam plate to the side mold plate 5 and the T-shaped mold plate 4 in the demolding process, ensures the corner integrity and surface flatness of the T-shaped beam plate, and reduces the generation of internal stress cracks of the concrete through staged temperature control, so that the curing energy consumption is reduced by about 20%-30%. The continuous paving operation of the distributing machine makes the pouring efficiency 3-5 times higher than that of the traditional manual operation, and the sealing design of the torpedo tank controls the concrete slump loss rate within 2%.

[0101] The present application further proposes that the transfer trolley 7 can move to the transfer groove 21, the bottom of the transfer trolley 7 is provided with a steel wheel 71, the length of the transfer trolley 7 is greater than the width of the part of the T-shaped beam plate abutting to the transfer trolley 7, and the part of the transfer trolley 7 protruding from the T-shaped beam plate is provided with a lifting hole 72.

[0102] Among them, the transfer trolley 7 refers to a mobile device for carrying and transporting the formed T-shaped beam plate, which can be specifically realized by a flat trolley with a steel frame and a roller, and the bottom steel wheel 71 is movable. The steel wheel 71 refers to a metal roller installed at the bottom of the transfer trolley 7, which can be specifically realized by a forged steel wheel 71 with a bearing, capable of bearing heavy load and reducing rolling resistance. The lifting hole 72 refers to a circular through hole formed in the protruding part of the transfer trolley 7, which can be specifically formed by drilling or stamping process, so as to facilitate the lifting hook of the lifting equipment to pass through and be fixed.

[0103] Specifically, when the hydraulic support rod 23 jacks up the I-shaped bearing plate 24 to be flush with the strip-shaped die table 2, concrete is poured into the pouring area 11. After the concrete of the T-shaped beam slab is completed and the secondary curing is formed, the hydraulic support rod 23 is lowered, the I-shaped bearing plate 24 is removed, and the transfer trolley 7 is moved into the transfer groove 21. The length is designed to ensure that the T-shaped beam slab has protruding areas on both sides when placed. The lifting hole 72 is positioned away from the main body of the T-shaped beam slab. After the transfer trolley 7 enters the range of the lifting device, the lifting device directly lifts the transfer trolley 7 and the T-shaped beam slab through the lifting hole 72 without additional adjustment of the lifting device position.

[0104] Compared with the prior art, the conventional transfer trolley 7 has the same length as the beam slab, and the lifting device needs to be temporarily installed on both sides of the beam slab during lifting, which is easy to cause damage to the concrete surface. The present application lengthens the transfer trolley 7 and pre-installs the lifting hole 72 in the protruding part, so that the lifting force directly acts on the frame of the transfer trolley 7, avoiding stress on the beam slab body, while reducing the lifting preparation time.

[0105] Through the above technical scheme, the present application effectively prevents the concrete surface damage caused by contact or extrusion during lifting, improves the finished product transfer efficiency, and reduces the influence of lifting operation on the structural integrity of the beam slab.

[0106] In an embodiment, in the mountainous highway bridge construction project, due to the complex terrain conditions, the transportation and installation of the T-shaped beam slab bring certain difficulties, so higher requirements are put forward for the prefabrication quality and production efficiency of the T-shaped beam slab. The beam slab prefabrication integrated production line plays an important role in this project.

[0107] For T-shaped beam slabs with different spans and bearing requirements in the project, the technical personnel finely adjust the specifications and processing technology of the steel bars in the steel bar processing unit 02. For T-shaped beam slabs with large span and high bearing requirements, the diameter and number of steel bars are increased, and the welding process is optimized to ensure that the T-shaped steel bar framework 9 has sufficient strength and stability. In the moving die table 03 part, the corresponding specifications of the T-shaped beam slab and the side mold plate 5 are replaced according to the size of the T-shaped beam slab, and the size of the pouring area 11 is accurately adjusted by adjusting the limiting bolts and pads 26 on the steps 25 at both ends of the strip-shaped die table 2 and the limiting plate 58 inside the side mold plate 5, to ensure the forming accuracy of the T-shaped beam slab.

[0108] During the concrete pouring process, considering the mountainous construction environment and the characteristics of the concrete raw materials, the operating parameters of the torpedo tank and the distributing machine of the concrete pouring unit 05 are optimized. The mix proportion of the concrete is adjusted to improve the workability and fluidity of the concrete; at the same time, according to the requirements of the pouring speed and volume, the transportation frequency of the torpedo tank and the distributing speed of the distributing machine are reasonably arranged to ensure that the concrete is continuously and uniformly poured into the pouring area 11, avoiding problems such as pouring interruption and concrete segregation.

[0109] The steam curing unit 06 adopts an intelligent temperature control system according to the temperature change of the T-beam slab in the mountainous environment, monitors the temperature and humidity of the curing area in real time, and automatically adjusts the supply of steam and the curing time according to the strength growth data of the T-beam slab. On the premise of ensuring the quality of the T-beam slab, the curing cycle is shortened as much as possible, and the production efficiency is improved. In the demolding link, the synergistic effect of the demolding vibrator 8 and the hydraulic jack 12 makes the demolding process proceed smoothly, and the T-beam slab is smooth and damage-free after demolding. The finished product transfer unit 07 quickly transfers the T-beam slab to the storage area through a reasonable planning of the running route and the lifting sequence, saves time for the subsequent transportation and installation. Through the efficient operation of the production line, the project has completed the prefabrication task of the T-beam slab in a short time and with high quality, meeting the progress demand of the mountainous highway bridge construction.

[0110] The above only describes the embodiments of the present application and is not used to limit the present application. The present application can have various changes and variations for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the scope of claims of the present application.
