Description

Technical Field

[0001] The invention relates to the technical field of slipform construction, in particular to a silo wall construction method. Background Art

[0002] As a warehouse for storing bulk materials, silos can be divided into elevated silos and floor-standing silos according to the support form, and can be divided into bottom-unloading silos and side-unloading silos according to the unloading position. Bottom-unloading silos are particularly widely used. With the widespread application of silos in various industries, the diameter of silo structures is getting larger and larger, which requires the original construction technology to continuously break through in this aspect. Prestressed technology, slipform construction technology, and pneumatic formwork construction technology are gradually being used in silo construction.

[0003] At present, reinforced concrete silo is the most widely used storage structure. The reinforced concrete silo structure is mainly composed of the silo building, silo roof, silo wall, silo support structure, cylinder wall and foundation. (1) Silo building: The building above the silo roof usually has a single-story or multi-story factory building, which is not only equipped with feeding equipment and dust removal equipment; (2) Silo roof: When the diameter of the reinforced concrete silo structure is less than 15m, a beam-slab structure is usually used as the silo roof. When the diameter exceeds 15m, a reinforced concrete truncated cone shell or truncated spherical shell is usually used as the silo roof; (3) Silo wall: The silo wall needs to be able to withstand the horizontal pressure of the stored material according to factors such as the height and diameter of the silo; (4) Silo bottom: The silo bottom needs to withstand the vertical pressure of the stored material. Therefore, the following points need to be considered comprehensively: smooth unloading; clear load transfer and reasonable structural force; simple shape; less filling. (5) Silo support structure: The silo support structure will have a great impact on the stability of the overall structure of the silo. Therefore, when selecting the silo support structure, it is necessary to fully consider the silo's deadweight, possible storage weight, and the effects of various forces. (6) Foundation: Independent silos usually adopt extended foundations, ring plate foundations, circular plate foundations, shell foundations, etc.; when the silo has high load requirements on the foundation, pile foundations are usually used to improve the bearing capacity of the soil.

[0004] Among them, most of the existing reinforced concrete silo wall structure construction adopts the slipform construction process. The slipform process is a construction technology with high mechanization degree, fast construction speed, small site occupation, strong structural integrity, good seismic performance, guaranteed safe operation and significant environmental and economic benefits in the construction of cast-in-place concrete structure projects. At present, the hydraulic jack is mainly used as the power device to drive the formwork or sliding frame to slide along the newly formed concrete surface, and the concrete is poured into the formwork groove in layers to the set height.

[0005] Our company undertook the TSGLY-TC1 section of the silo project for the 100,000-ton grain and oil berth project in the Henggangsha operation area of ​​the Tiansheng Port area of ​​Nantong Port. It mainly built 48 silos with a diameter of 25m and road yards around the silos. The silo walls were constructed using the slipform technology. During the slipform construction, maintaining the horizontal synchronous sliding of the entire formwork system is the key to ensuring the construction quality of the sliding formwork, and is also an important factor affecting the verticality of the building. Due to the asynchronous phenomenon of the jack during the sliding process, a lift difference is generated between the various parts of the formwork system, resulting in deviation of the silo wall, affecting the quality of the project, changing the stress state of the structural steel bars, causing hidden dangers to the project, and in serious cases endangering the safety of the construction site, leading to major safety accidents. Summary of the invention

[0006] In view of the above-mentioned technical deficiencies, the object of the present invention is to provide a silo wall construction method, which has the advantages of reducing the possibility of deviation of the silo wall and improving the safety of the construction process.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a silo wall construction method, comprising the following steps: Step 1: Install the slipform platform S1: After the silo foundation construction is completed, clean the base, tie the silo wall steel bars within the initial height and install the embedded parts; S2: Install the lifting frame, and make sure the bottom of the lifting frame legs are level with the bottom of the formwork; S3: Install the enclosure, with two enclosures and one each along the inner and outer sides of the silo wall, and the enclosure is placed on the legs of the lifting frame, aligned and leveled, and then welded and fixed. The outer slope of the enclosure is controlled to be 0~0.5mm, and the inner slope is controlled to be 1~1.6mm; S4: Install the template, which is fixed by a pressing plate, a hook and an adjacent ring; S5: Install the support frame, which is set beside the formwork and fixed to the legs of the lifting frame. Use a tower crane to hoist the internal platform and the external platform into place. The internal platform and the external platform are set up on the support frame. When the internal platform and the external platform slide to a height of 2m, install the hanging scaffolding, which is installed on the support frame and the lifting frame. S6: Install the center plate and the tie rod. The tie rod is welded to the center plate and fastened to the lifting frame with a basket bolt. When adjusting and tightening the tie rod, first pre-tighten all the tie rods, then place a level on the lifting frame beam, and tighten the tie rod until the lifting frame beam is horizontal; S7: Set up the delivery components for transport equipment and construction materials on the internal platform; Step 2: Install the power and hydraulic system S1: Install the jacks and hydraulic control system. Arrange the jacks evenly in a circle, connect the oil circuits, connect the jacks to the lower crossbeam of the lifting frame with high-strength bolts, install the power and lighting circuits, refuel, pressure test, and exhaust the hydraulic system; S2: Insert the support rod, which is buried in the concrete of the silo wall. The upper end of the support rod is connected to the next section of the support rod at a distance of 0.3m from the upper beam of the lifting frame. The support rods are set to different lengths during assembly so that the joints are staggered during subsequent extension. Step 3: Sliding platform S1: Initial sliding and lifting. Concrete is poured in three layers in positive and negative directions with a 1000~1200mm formwork. When the strength of the first layer of concrete reaches about 0.2~0.4Mpa, trial sliding and lifting can be carried out. During trial sliding and lifting, all jacks should be raised by 5~10cm at the same time. When the concrete does not collapse after leaving the mold and is not lifted by the formwork (finger marks can be seen when pressing with fingers, and the mortar does not stick to fingers), the initial lifting is carried out. Generally, 200~300mm can be lifted at a time during the initial lifting stage. S2: Normal sliding. During normal sliding, the time interval between two slidings is determined by the time it takes for the provided concrete to reach a cubic strength of 0.2~0.4MPa, which is generally controlled at about 1.5~2 hours. A special person is arranged to observe the demoulding strength of the concrete on the scaffolding hand. It is advisable for the demoulding concrete to have a slight handprint on it. The controlled pouring height of each pouring layer should be 250-350mm. Tie a layer of steel bars (casting layer) and pour a layer of concrete. Concrete is poured in positive and reverse cycles. When the temperature is high, it is lifted 1~2 strokes in the middle, and one stroke is lifted every half an hour during the sliding interval. S3: Final rise. When the template slides to 1m below the design elevation, the sliding speed should be slowed down and accurate leveling and alignment should be carried out. The leveling and correction of the entire template should be completed before sliding to the last template at the top elevation, so that the top can be evenly circled to ensure the correct top elevation and position. Within 4 to 8 hours after the last layer of concrete is poured, it should be lifted every half an hour, 5 to 10mm each time, until the template is no longer bonded to the concrete; Step 4: After the silo pouring is completed, remove the slipform platform.

[0008] By adopting the above technical scheme and following the principles of layering, overlapping and transformation in concrete pouring, it is possible to prevent large differences in the strength of the concrete leaving the mold and the frictional resistance, which may cause the platform to be unable to rise horizontally, and reduce the possibility of the formwork being deviated by the force in the same direction for a long time. At the same time, when the silo deviates, the method of pressing weight on one side is adopted, and the opposite side of the deviation in the diameter direction of the deviation is temporarily used as a material stacking point. The equipment and construction materials are quickly transported to the appropriate position through the transport components, and the platform is deflected by the counterweight, so that the silo wall is kept horizontal, thereby achieving the purpose of correction.

[0009] Preferably, concrete pouring should follow the principles of layering, intersection and change of direction. Intersection means pouring in closed layers every 30 cm. Changing direction means that each layer of concrete should be poured in a clockwise and counterclockwise cycle. The interval between each layer should not be greater than the initial setting time of the concrete.

[0010] Through the above technical solution, the concrete is poured in a clockwise and counterclockwise cycle to reduce the possibility of the formwork being deflected due to long-term force in the same direction.

[0011] Preferably, guardrails are fixed on the internal platform, external platform and hanging scaffolding. The height of the guardrails on the internal platform and the external platform is not less than 1800mm, and the height of the guardrails on the hanging scaffolding is not less than 1200mm. The horizontal spacing between every two guardrails is 1500mm. A safety net covering the gap between two adjacent guardrails is fixed on each guardrail.

[0012] Through the above technical solution, a safety net covering the gap between two adjacent guardrails is fixed on each guardrail to protect the workers on the internal platform, external platform and hanging scaffolding, prevent falls and ensure construction safety.

[0013] Preferably, each of the lifting frames is equipped with a level tube with scales marked on it, and each level tube is connected by a hose, and a colored liquid is injected into the level tube.

[0014] Through the above technical solution, when there is a height difference in the lifting jack, the water levels of the level tubes must be different, and the height difference value can be read on the scale.

[0015] Preferably, the lifting frame is provided with a vertical ruler with a length of about 1m, and the surface of the vertical ruler is marked with 5mm scales, and the support rod is provided with a movable pointer cooperating with the vertical ruler on the side facing the vertical ruler.

[0016] Through the above technical scheme, the movable pointer is bolted on the support rod at certain elevations. When the lifting frame drives the scale to rise, the reading of the movable pointer on the scale keeps changing. When there is a height difference when the jacks climb, the readings of each indicator are different. The difference in readings between the scales is the height difference between the jacks. During construction, as the scale rises, the movable pointer should also rise once at certain heights, and the elevation of each point on the support rod should be leveled with a level.

[0017] Preferably, the transport assembly includes an inner rail and an outer rail arranged along the circumference of the inner platform and fixedly connected to the upper surface of the inner platform, a plurality of movable plates slidably connected to the inner rail and the outer rail are arranged above the inner rail and the outer rail, and the lower surface of each movable plate is rotatably connected to an inner pulley located beside the inner rail and an outer pulley located beside the outer rail, the inner circumference of the inner rail is integrated with an inner convex strip adapted to the inner pulley, and the outer circumference of the outer rail is integrated with an outer convex strip adapted to the outer pulley, the inner convex strip extends into the inner pulley and is slidably connected to the inner pulley, and the outer convex strip extends into the outer pulley and is slidably connected to the outer pulley.

[0018] Through the above technical solution, the inner rail and the outer rail cooperate to support the movable plate, the inner pulley and the outer pulley on the movable plate cooperate to clamp the inner rail and the outer rail and are slidably connected with the inner rail and the outer rail, and the inner pulley cooperates with the inner convex strip, and the outer pulley cooperates with the outer convex strip to further improve the stability of the connection between the inner rail, the outer rail, the inner pulley and the outer pulley, and reduce the possibility of the movable plate escaping from the inner rail and the outer rail. Equipment and construction materials are placed on the movable plate, which is convenient for moving equipment and construction materials and improves construction efficiency.

[0019] Preferably, the movable plate is provided with a driving assembly for controlling the movable plate to move along the inner track and the outer track.

[0020] Through the above technical solution, the driving assembly provides power to drive the movable plate to move, thereby driving the equipment and construction materials on the movable plate to move to a suitable position.

[0021] Preferably, the driving assembly includes a transmission shaft that passes through the movable plate and is rotatably connected to the movable plate, the transmission shaft is located between the inner track and the outer track, and one end of the transmission shaft that passes through the movable plate is coaxially fixed with a gear located between the inner track and the outer track, and an annular rack that meshes with the gear is fixed on the side of the outer track facing the inner track, and a motor that drives the transmission shaft to rotate is fixed on the movable plate.

[0022] Through the above technical solution, the motor provides power to drive the transmission shaft coaxially fixed with the motor output shaft to rotate. The rotation of the transmission shaft will drive the gear coaxially fixed with the transmission shaft to rotate. The gear rotates and meshes with the annular rack, thereby driving the movable plate to move. Construction materials can be transferred without the intervention of construction personnel, thereby improving construction efficiency.

[0023] Preferably, two relatively arranged slide rails are fixed on the movable plate, and the long sides of the two slide rails are perpendicular to the long sides of the movable plate. Each of the slide rails is slidably connected with a slider, and a movable plate with a C-shaped cross-section is fixed to the end of several sliders facing away from the slide rails. The movable plate is provided with a gripping assembly for gripping a storage box for equipment and construction materials.

[0024] Through the above technical solution, by setting up a gripping component, it is convenient to move the storage box for construction materials containing the equipment, which does not require manual handling and saves manpower. The cooperation of the slide rail and the slider plays a guiding role in the movement of the movable plate.

[0025] Preferably, the gripping assembly includes a mounting seat fixed to the movable plate by a connecting rod, the mounting seat has a C-shaped cross-section, and both ends of the mounting seat are hingedly connected to a rocker arm, and the two rocker arms are hingedly connected to a support with a C-shaped cross-section on the side away from the mounting seat, and the support and the mounting seat are also hingedly connected by two push rods with a V-shaped cross-section, and each push rod is connected and fixed by a reinforcing rod, and a dead stop is fixed on the mounting seat, which interferes with the push rod and limits the position of the push rod.

[0026] Through the above technical solution, the staff pushes the push rod, and the movement of the push rod will drive the movement of the support hinged to the push rod, and then push the mounting seat. The movement of the mounting seat will drive the connecting rod, movable plate and slider of the integrated structure to move, until the support moves to the outside of the containing box and contacts with the lower surface of the annular protrusion. The staff then pushes the push rod in the opposite direction, and the push rod rotates to drive the support to move back, thereby driving the containing box to move up and be stored between the support, mounting seat and movable plate, and then pushes the movable plate back to the initial position, so as to facilitate the movement of the containing box to the specified position.

[0027] The beneficial effects of the present invention are as follows: by following the principles of layering, overlapping and transformation in concrete pouring, it is prevented that the strength of the concrete coming out of the mold is large, the friction resistance is large, and the possibility of the template being deviated by the force in the same direction for a long time is reduced. At the same time, when the silo deviates, the method of pressing weight on one side is adopted, and the opposite side of the deviation is temporarily used as a material stacking point in the diameter direction of the deviation. The equipment and construction materials are quickly transported to the appropriate position through the transport assembly, and the platform is deflected by the counterweight, so that the silo wall is kept level, thereby achieving the purpose of correction.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] A silo wall construction method, such as Figure 1-13 , including the following steps: Step 1: Install the slipform platform S1: The silo foundation 1 is specifically the lower funnel layer, which includes frame columns, longitudinal and transverse beams, ring beams, and grain loading layer plates. This is an existing construction structure, so it will not be described in detail here. After the construction is completed, clean the silo foundation 1, check the position of the positioning steel bars, check whether the surface of the template 5 is clean and apply the release agent, find the center on the sliding starting surface, mark the radius position of the column 301 on the inner side of the lifting frame 3, use the theodolite according to the divided angle, find the correct position of the lifting frame 3 and pop it out with an ink line, tie the silo wall 2 steel bars within the initial height and install the embedded parts, and the silo wall 2 steel bars The cross section is annular, the vertical reinforcement lap length is not less than 35d, the joint positions are staggered, the joint reinforcement section does not exceed 25%, 1 / 4 staggered, the annular horizontal reinforcement lap length is 50d, the joint positions are staggered, the joint horizontal direction is not less than one lap length, one lap joint is allowed for every three reinforcements in the same vertical section, the internal and external horizontal reinforcements are also staggered evenly, the first section of reinforcement is tied to a height of 1.3 meters, which can be done before the installation of the outer formwork, and the subsequent reinforcement needs to be interspersed with the lifting of the formwork 5 (that is, the reinforcement is not tied when pouring concrete, and the concrete is not poured when the reinforcement is tied); S2: Install the lifting frame 3. The main function of the lifting frame 3 is to prevent the lateral deformation of the template 5. During the sliding process, all vertical loads are transferred to the jack 12, and then to the support rod 13 through the jack 12. The height of the lifting frame 3 in this project is 2390mm, and the net width is 740mm. The lifting frame 3 includes two axial columns 301 and two horizontal beams 302. The columns 301 and the beams 302 are fixedly connected by bolts. There are 56 lifting frames 3 on each base. The bottom of the lifting frame 3 column 301 is level with the bottom of the template 5. S3: Install the enclosure 4. The enclosure 4 is made of L75×8 angle steel. The enclosure 4 at the support frame 6 is made of [20 channel steel. The enclosure 4 is subjected to horizontal loads (concrete lateral pressure, impact force and wind force) and vertical loads (self-weight of the template 5 and the enclosure 4, friction resistance, self-weight of the operating platform and construction load) to prevent the lateral deformation of the template 5. The enclosure 4 includes an inner enclosure 401 and an outer enclosure 402. The inner enclosure 401 and the outer enclosure 402 are each two and are respectively provided along the inner and outer sides of the silo wall 2, and one is provided at the top and the bottom. The distance between the two inner circles 401 and the two outer circles 402 is 750mm, wherein the arc part is formed by mechanical bending and manual trimming, the inner circle 401 and the outer circle 402 are placed on the column 301 of the lifting frame 3, the upper and lower horizontal joints of the inner circle 401 and the outer circle 402 are staggered by 1m, and are welded and fixed after alignment and leveling, so as to further improve the stability of the circle 4 and the template 5, the outer slope control value of the circle 4 is 0~0.5mm, and the inner slope control value is 1~1.6mm; S4: Install the template 5, which includes an inner template 501 and an outer template 502. The inner template 501 adopts a 600*1200mmx25mm shaped steel template, and the outer template 502 adopts a 3000x1200mmx35mm shaped steel template. A small amount of 1200mm high, 200mm wide, 150mm, 100mm thick steel templates are also used to fill the gaps, ensuring that the warehouse wall 2 is circled and arranged vertically. The template 5 is fixed by a pressing plate, a hook and an adjacent enclosure 4; S5: Install the support frame 6, which is arranged beside the template 5 and fixed to the column 301 of the lifting frame 3. Use a tower crane to hoist the internal platform 7 and the external platform 8 into place. The internal platform 7 and the external platform 8 are erected on the support frame 6. A scissors brace is arranged inside and outside the internal platform 7 and the external platform 8, and two circular arc horizontal bars are arranged inside and outside (two bars on the top and two bars on the bottom, a total of four bars) to reinforce the internal platform 7 and the external platform 8. When the internal platform 7 and the external platform 8 are supported to slide to a height of 2m, install the hanging scaffold 9, which is fixedly connected to the support frame 6 and the lifting frame 3 with fasteners, and is used to check the demoulding strength of the concrete after the warehouse wall 2 is demoulded, to trim the warehouse wall 2, to deal with quality defects, to clean out the reserved and embedded parts, and to smooth the original slurry, etc.; S6: Install the center plate 10 and the tie rod 11. The center plate 10 is made of Ø600 thick 12 steel plate, and the tie rod 11 is made of Ø14 threaded steel. The tie rod 11 is welded to the center plate 10 every other lifting frame 3. The weld length is required to be 100mm on both sides. It is fastened with the lifting frame 3 using a basket bolt. When adjusting and tightening the tie rod 11, all the tie rods 11 should be pre-tightened first, and then a level ruler should be placed on the cross beam 302 of the lifting frame 3, and the tie rod 11 should be tightened until the cross beam 302 of the lifting frame 3 is level. S7: Arrange the transport equipment and the transport assembly 14 of the construction materials on the internal platform 7; Step 2: Install the power and hydraulic system S1: Install the jack 12 and the hydraulic control system. The jacks 12 are evenly arranged in a circle and correspond to the lifting frames 3 one by one. Connect the oil circuit. The jack 12 is specifically a GYD-60 type jack 12. The hydraulic control system is specifically a HY-56 type hydraulic control system. The jack 12 is fixedly connected to the crossbeam 302 of the lifting frame 3 with high-strength bolts. Install the power and lighting circuits, refuel the hydraulic system, test the pressure, and exhaust the air. S2: insert the support rod 13. In order to reduce the possibility of deformation of the support rod 13, the support rod 13 should be made of Φ48×3.0 steel pipe. The support rod 13 is buried in the concrete of the warehouse wall 2. The upper end of the support rod 13 is connected to the next section of the support rod 13 at a distance of 3020.3m from the upper beam of the lifting frame 3. A hydraulic pipe compressor is used at the joint to compress one end of the support rod with an outer diameter of Ø48 to an outer diameter of Ø40 for socket connection. Then, after circumferential electric welding along the joint, it is polished and smoothed to facilitate smooth sliding through the jack 12. The support rod 13 is set with different length specifications during assembly so that the joints are staggered during subsequent extension. The number of joints at each horizontal section should not exceed 25% of the total number of roots. Therefore, the first section of the support rod should have four lengths, namely 3, 4, 5, and 6m. The jacks are inserted into their respective support rods 13. If there is oil on the support rod 13, it should be cleaned in time; S3: Before the template 5 starts to slide up, the elevation of the inner platform 7, the outer platform 8 and the jack 12 are measured and leveled with a level, and the support rod 13 is leveled with a level every 1m, and 4 self-made large plumbs are hung at the four corners of the outer side of the outer platform 8, twice per shift, and a written record is made; Step 3: Sliding platform S1: Initial sliding and lifting. Concrete is poured in three layers in positive and negative directions with a 1000~1200mm formwork 5. Each stroke of the sliding formwork construction is 30mm. Check once every 6 strokes and make timely adjustments if there is a lift difference. When the strength of the first layer of concrete reaches about 0.2~0.4Mpa, trial sliding and lifting can be carried out. During trial sliding and lifting, all jacks 12 should be raised by 5~10cm at the same time. When the concrete does not collapse after leaving the mold and is not lifted by the formwork 5 (finger marks can be seen when pressing with fingers, and the mortar does not stick to fingers), the initial lifting is carried out. Generally, 200~300mm can be lifted at a time during the initial lifting stage. During the initial sliding, close attention should be paid to the pouring height of each layer of concrete and the layered vibration should be carried out to ensure that the lateral pressure on the formwork 5 is consistent and reduce the possibility of displacement and deformation of the formwork 5 and the platform system. S2: Normal sliding. During normal sliding, the time interval between two slidings is determined by the time when the provided concrete reaches a cubic strength of 0.2~0.4MPa, which is generally controlled at about 1.5~2 hours. A special person is arranged to observe the demoulding strength of the concrete on the scaffolding hand. It is advisable that the demoulding concrete has a slight handprint on it. The controlled pouring height of each pouring layer should be 250-350mm, that is, ten strokes, tying a layer of pouring layer steel bars and pouring a layer of concrete. The concrete is poured in positive and reverse cycles. When the temperature is high, it is lifted by 1~2 strokes in the middle. The sliding interval is lifted by one stroke every half an hour. When sliding to a reserved door opening, the maximum empty height of the support rod 13 should be limited to 1.0m; S3: Final lifting. When the template 5 slides to 1m below the design elevation, the sliding speed should be slowed down, and accurate leveling and alignment should be carried out. The leveling and correction of the entire template 5 should be completed before sliding to the last mold at the top elevation, so that the top can be evenly circled to ensure the correct top elevation and position. Within 4 to 8 hours after the last layer of concrete is poured, it should be lifted every half an hour, 5 to 10mm each time, until the template 5 is no longer bonded to the concrete; Step 4: After the silo pouring is completed, unload the load that can be unloaded on the platform in time and remove the slipform platform.

[0033] like Figure 1 and Figure 2 and Figure 3 and Figure 4 Our company built 48 silos with a diameter of 25m. Each group of four adjacent silos has a distance of 3m from the outer wall of each group of silos. In this project, every four slipform platforms are connected into an integral platform. While retaining the single silo structure, steel pipes are used to connect the outer sides of adjacent silos, and purlins and planks are fully laid to make the operating platforms communicate with each other, which is convenient for the flow of personnel between single silos. Two truck pumps are used to pour concrete for the silos connected as an integral platform. The pouring time of the two silos is about 1 hour to complete a stroke, shortening the construction period.

[0034] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 , shovel the concrete on the platform into the inner formwork 501 and the outer formwork 502, and vibrate and pour the concrete continuously. The pouring of concrete follows the principles of layering, crossing and changing direction. The layer crossing means pouring in closed layers every 30 cm to ensure that the friction of concrete on the formwork 5 remains symmetrical and reduces the possibility that the platform cannot rise horizontally due to large differences in the strength of the concrete out of the formwork and the frictional resistance. Changing direction means that each layer of concrete should be poured in a clockwise and counterclockwise cycle to prevent the formwork 5 from being twisted due to long-term force in the same direction. The interval time between each layer should not be greater than the initial setting time of the concrete, and the retarding time of the concrete should be strictly controlled at about 6 to 8 hours.

[0035] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 , enter the mold and vibrate in the positive and negative directions at the same time to avoid cold joints at the end of one-way construction. The top surface height of concrete should be 550mm lower than the template. After the concrete is shoveled into the space between the inner template 501 and the outer template 502, it should be vibrated in time with an inserted vibrating rod. During operation, press the "fast insertion and slow withdrawal" and "rod connection" buttons and adopt "parallel" vibration. The vibration time for each point is 20s~30s. When the concrete surface no longer sinks significantly and no bubbles appear, and the surface is covered with slurry, the vibration can be stopped. When vibrating the upper layer of concrete, the vibrating rod should be inserted into the lower layer of concrete no more than 5cm to eliminate the joints between the two layers.

[0036] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 There is a 1.2mm gap between the template 5 and the warehouse wall 2 every time the template 5 is raised (300mm high), which is prone to leakage and hanging of slurry. In order to reduce the possibility of concrete hanging of slurry, a sponge strip is nailed under the template 5.

[0037] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 During the sliding process, maintaining the horizontal and synchronous sliding of the entire formwork 5 system is the key to ensuring the construction quality of the sliding formwork, and is also an important factor affecting the verticality of the building. Due to the asynchronous phenomenon of the jack 12 during the sliding process, a lift difference is generated between the various parts of the formwork 5 system, resulting in a torsional deviation of the silo wall 2, affecting the quality of the project. In order to solve the above problems, a correction check is carried out every sliding shift of the sliding formwork construction.

[0038] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 In measuring the horizontality of the silo wall 2, the correction and inspection method is to install a level tube on each lifting frame 3, the level tube is marked with scales, and each level tube is connected by a hose, and colored liquid is injected into the level tube. When there is a height difference on the sliding jack 12, the water level of each level tube must be different, and the height difference value can be read on the scale.

[0039] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5The correction and inspection method also includes a vertical ruler with a length of about 1m on the lifting frame 3, and a 5mm scale is marked on the ruler surface of the vertical ruler. A movable pointer that cooperates with the vertical ruler is provided on the side of the support rod 13 facing the vertical ruler. The movable pointer is fixed to the support rod 13 with bolts at certain elevations. When the lifting frame 3 drives the ruler to rise, the reading of the movable pointer on the ruler keeps changing. When there is a height difference when the jack 12 climbs, the indicated readings are different. The difference in readings between the rulers is the climbing height difference between the jacks 12. During construction, as the ruler rises, the movable pointer should also rise once at a certain height, and the elevation of each point on the support rod 13 should be leveled with a level.

[0040] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 In the measurement of the verticality of the silo wall 2, the correction and inspection method also includes setting a plumb measuring device at the four corners of each group of silo walls 2. The plumb weighs 10 to 15 kg and is suspended at the lower part of the external platform 8 with a thin steel wire. A fixed control point is set on the ground below the corresponding plumb. A pulley and a wire releaser are set at the upper end of the steel wire of the plumb. As the template 5 gradually slides upward, the steel wire gradually lengthens. After sliding to a certain height, the direction and value of the platform offset can be determined at any time from the relative displacement between the plumb and the control point.

[0041] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 When the silo wall 2 is found to be tilted during the calibration inspection, it is corrected by using the method of weighting on one side. Specifically, the opposite side of the offset diameter is temporarily used as a material stacking point, and the platform is deflected by the counterweight.

[0042] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 However, construction workers usually manually carry equipment and construction materials, which wastes manpower and affects construction efficiency. In order to reduce the above problems, a transportation component 14 for transporting equipment and construction materials is set on the internal platform 1.

[0043] like Figure 8 and Fig. 9 and Fig.10 and Fig.11 and Fig.12The transport assembly 14 includes an inner rail 1401 and an outer rail 1402 which are arranged along the circumference of the inner platform 7 and are detachably fixedly connected to the upper surface of the inner platform 7 by bolts. The inner rail 1401 and the outer rail 1402 are both spliced ​​in multiple sections to form an annular overall structure adapted to the inner platform 7, and the splicing positions of the inner rail 1401 and the outer rail 1402 are staggered to facilitate the installation and disassembly of the inner rail 1401 and the outer rail 1402. The center lines of the inner rail 1401 and the outer rail 1402 coincide with the center line of the inner platform 7. The outer diameter of the inner rail 1401 is smaller than the inner diameter of the outer rail 1402. The inner rail 1401 and the outer rail 1402 are both spaced a certain distance from the lifting frame 3, so as not to affect the walking work of the construction personnel. A plurality of movable plates 1403 are provided above the inner rail 1401 and the outer rail 1402, which are slidably connected to the inner rail 1401 and the outer rail 1402. The lower surface of each movable plate 1403 is rotatably connected to an inner pulley 1404 located beside the inner rail 1401 and an outer pulley 1405 located beside the outer rail 1402. The inner periphery of the inner rail 1401 is integrated with an inner convex strip 1406 adapted to the inner pulley 1404, and the outer periphery of the outer rail 1402 is integrated with an outer convex strip 1407 adapted to the outer pulley 1405. The inner convex strip 1406 extends into the inner pulley 1404 and is slidably connected to the inner pulley 1404, and the outer convex strip 1407 extends into the outer pulley 1405 and is slidably connected to the outer pulley 1405.

[0044] like Figure 8 and Fig. 9 and Fig.10 and Fig.11 and Fig.12 The inner rail 1401 and the outer rail 1402 cooperate to support the movable plate 1403, the inner pulley 1404 and the outer pulley 1405 on the movable plate 1403 cooperate to clamp the inner rail 1401 and the outer rail 1402 and are slidably connected with the inner rail 1401 and the outer rail 1402, and the inner pulley 1404 cooperates with the inner convex strip 1406, and the outer pulley 1405 cooperates with the outer convex strip 1407 to further improve the stability of the connection between the inner rail 1401, the outer rail 1402, the inner pulley 1404 and the outer pulley 1405, and reduce the possibility of the movable plate 1403 escaping from the inner rail 1401 and the outer rail 1402. Equipment and construction materials are placed on the movable plate 1403, which is convenient for moving equipment and construction materials and improves construction efficiency.

[0045] like Fig. 9 and Fig.10The movable plate 1403 is provided with a driving component for controlling the movable plate 1403 to move along the inner track 1401 and the outer track 1402. The driving component provides power to drive the movable plate 1403 to move, thereby driving the equipment and construction materials on the movable plate 1403 to move to a suitable position. No manual operation is required and the work of the construction personnel is not affected.

[0046] like Fig. 9 and Fig.10 The driving assembly includes a transmission shaft 1408 that passes through the moving plate 1403 and is rotatably connected to the moving plate 1403. The transmission shaft 1408 is located between the inner track 1401 and the outer track 1402. One end of the transmission shaft 1408 that passes through the moving plate 1403 is coaxially fixed with a gear 1409 located between the inner track 1401 and the outer track 1402. A ring rack meshing with the gear 1409 is fixed on the side of the outer track 1402 facing the inner track 1401. A motor 1410 that drives the transmission shaft 1408 to rotate is fixed on the moving plate 1403.

[0047] like Fig. 9 and Fig.10 The motor 1410 provides power to drive the transmission shaft 1408 coaxially fixed with the output shaft of the motor 1410 to rotate. The rotation of the transmission shaft 1408 drives the gear 1409 coaxially fixed with the transmission shaft 1408 to rotate. The gear 1409 rotates and meshes with the annular rack, thereby driving the movable plate 1403 to move. Construction materials can be transferred without the intervention of construction personnel, thereby improving construction efficiency.

[0048] like Fig.11 and Fig.12 and Fig.13 Two relatively arranged slide rails 18 are fixed on the movable plate 1403, and the long sides of the two slide rails 18 are perpendicular to the long sides of the movable plate 1403. Each of the slide rails 18 is slidably connected with a slider 19. A movable plate 20 with a C-shaped cross-section is fixed on one end of several sliders 19 away from the slide rails 18. A gripping assembly 21 for gripping a storage box 22 for holding equipment and construction materials is provided on the movable plate 20. By setting the gripping assembly 21, it is convenient to move the storage box 22 for construction materials containing equipment, and no manual handling is required, which saves manpower. The cooperation between the slide rails 18 and the sliders 19 guides the movement of the movable plate 20.

[0049] like Fig.11 and Fig.12 and Fig.13The gripping assembly 21 includes a mounting seat 2102 fixed to the movable plate 20 by a connecting rod 2101, the mounting seat 2102 has a C-shaped cross-section, and both ends of the mounting seat 2102 are hingedly connected with a rocker rod 2103, and the two rocker rods 2103 are hingedly connected with a support 2104 with a C-shaped cross-section on the side away from the mounting seat 2102, and the support 2104 and the mounting seat 2102 are also hingedly connected by two push rods 2105 with a V-shaped cross-section, and the push rods 2105 are hingedly connected to the support 2104 and the mounting seat 2102 by short axes, and each of the push rods 2105 is connected and fixed by a reinforcing rod 2106, and a dead stop 2107 that contacts the push rod 2105 and limits the position of the push rod 2105 is fixed on the mounting seat 2102.

[0050] like Fig.11 and Fig.12 and Fig.13 , the staff pushes the push rod 2105, and the movement of the push rod 2105 will drive the support 2104 hingedly connected to the push rod 2105 to move, and then push the mounting seat 2102. The movement of the mounting seat 2102 will drive the connecting rod 2101, the movable plate 20 and the slider 19 of the integrated structure to move, until the support 2104 moves to the outside of the receiving box 22 and contacts the lower surface of the annular protrusion 2201. The staff then pushes the push rod 2105 in the opposite direction, and the push rod 2105 rotates to drive the support 2104 to move back, thereby driving the receiving box 22 to move up and be stored between the support 2104, the mounting seat 2102 and the movable plate 20, and then pushes the movable plate 20 back to the initial position, so as to facilitate the movement of the receiving box 22 to the specified position.

[0051] like Fig.11 and Fig.12 and Fig.13 The receiving box 22 is a square frame structure with a hollow inner cavity and an open top. The outer periphery of the top of the receiving box 22 is integrated with an annular protrusion 2201 that is adapted to the support 2104.

[0052] like Fig.11 and Fig.12 and Fig.13In order to reduce the possibility that the push rod 2105 shakes during transportation and causes the storage box 22 to fall out of the support 2104, a limit tube 23 with a hollow inner cavity and openings at both ends is fixed to the outer wall of the support 2104, and a connecting rope 24 is fixed to the mounting seat 2102. A counterweight pin 25 adapted to the limit tube 23 is fixed to the end of the connecting rope 24 away from the mounting seat 2102, and a baffle 26 is fixed to the end of the counterweight pin 25. The outer diameter of the baffle 26 is larger than the inner diameter of the limit tube 23. When the support 2104 supports the storage box 22, the pin is inserted into the limit tube 23, and the baffle 26 conflicts with the top of the limit tube 23. The support 2104 and the mounting seat 2102 are connected by the connecting rope 24, the pin and the limit tube 23, thereby reducing the possibility of the storage box 22 falling during the movement of the moving plate 1403.

[0053] When performing the correction operation, several containing boxes 22 are moved to the diameter direction of the offset. After moving to the opposite side of the offset, the movable plate 1403, the inner rail 1401 and the outer rail 1402 are fixed by bolts to reduce the possibility of the movement of the movable plate 1403 and the containing box 22 affecting the correction, and at the same time reduce the possibility of the movable plate 1403 shaking under windy and rainy conditions.

[0054] like Figure 1 and Figure 2 and Figure 3 and Figure 4 Guardrails 15 are fixed on the internal platform 7, the external platform 8 and the hanging scaffolding 9. The height of the guardrails 15 on the internal platform 7 and the external platform 8 is not less than 1800 mm, and the height of the guardrails 15 on the hanging scaffolding 9 is not less than 1200 mm. The horizontal spacing between every two guardrails 15 is 1500 mm. A safety net 16 covering the gap between two adjacent guardrails 15 is fixed on each guardrail 15 to protect the workers on the internal platform 7, the external platform 8 and the hanging scaffolding 9, prevent falls, and ensure construction safety.

[0055] like Figure 1 and Figure 2 and Figure 3 and Figure 4 A ladder 17 connected to the scaffolding 9 is provided on both the internal platform 7 and the external platform 8. The ladder 17 connects the internal platform 7 and the scaffolding 9 below the internal platform 7, the external platform 8 and the scaffolding 9 below the external platform 8.

[0056] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5While lifting the template 5, use a wooden hammer to knock on the back of the template 5 to remove the adhesive between the concrete and the template 5, thereby reducing the possibility of damage to the concrete warehouse wall 2 due to excessive friction when the template 5 moves up due to the unevenness of the template 5 facing the concrete side.

[0057] When it is necessary to transport equipment and construction materials, the equipment and construction materials are placed in the inner cavity of the container 22, and then the push rod 2105 is grasped and manually pushed. The movement of the push rod 2105 drives the support 2104 hingedly connected to the push rod 2105 to rotate. The rotation of the support 2104 drives the swing rod 2103 hingedly connected to the support 2104 to rotate, pushing the mounting seat 2102. The movement of the mounting seat 2102 drives the connecting rod 2101 and the movable rod 2103 of the integrated structure to rotate. The movable plate 20 and the slider 19 move until the support 2104 moves to the outside of the receiving box 22 and contacts the lower surface of the annular protrusion 2201. The staff pushes the push rod 2105 in the opposite direction. The push rod 2105 rotates to drive the support 2104 to move back, thereby driving the receiving box 22 to move up and be stored between the support 2104, the mounting seat 2102 and the movable plate 20. Then, the movable plate 20 is pushed back to the initial position. At this time, the receiving box 22 is located above the movable plate 1403. Turn on the motor 1410 and provide power through the motor 1410 to drive the transmission shaft 1408 coaxially fixed with the output shaft of the motor 1410 to rotate. The rotation of the transmission shaft 1408 will drive the gear 1409 coaxially fixed with the transmission shaft 1408 to rotate. The gear 1409 rotates and meshes with the annular rack, thereby driving the movable plate 1403 and the containing box 22 connected to the movable plate 1403 to move to the designated position. There is no need for manpower to carry the construction materials to the appropriate position, which saves manpower and improves construction efficiency.

[0058] When a height difference occurs on the lifting jack 12, the water levels of various level tubes are different, and the height difference value is read. At the same time, when a height difference occurs when the jack 12 climbs, each movable pointer indicates a different reading. The difference in readings between the scales is the climbing height difference between the jacks 12. At this time, the transport component 14 and the gripping component 21 cooperate to transport the equipment and construction materials to the offset diameter direction and the opposite side of the offset. The counterweight is used to deflect the platform to achieve the purpose of correction.

[0059] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
