Description

Technical Field

[0001] The invention relates to the technical field of cast-in-place concrete silo structure slipform construction, in particular to a concrete silo climbing rail slipform system. Background Art

[0002] In the prior art, an open-frame structure slipform system is usually used to construct the wall of a concrete silo. The specific scheme is as follows: an open-frame support frame is set at an interval of about 2m along the circumference of the wall, and a support rod is erected at the center of the wall thickness range. The support rod is supported on the open-frame. There is a hydraulic jack on the upper part of the support rod. Templates are hung on both sides of the open-frame. The height of the template is about 1.2m. All the open-frames are pulled to the center of the entire silo in a radial state by steel wire ropes. A disc is set at the center to fix the steel wire ropes. During construction, after pouring 30cm of concrete, all jacks need to be driven upward to drive the open-frame and the template to slide upward. At this time, the concrete at the bottom of the template slides out of the template, and the structure begins to take shape. In this way, the upward construction of the silo wall can be completed by non-stop operation for 24 hours.

[0003] In the prior art, the sliding formwork is driven to rise by the cooperation of the jack and the support rod inside the cylinder wall. The scissor frame is arranged horizontally just above the cylinder wall and penetrates the cylinder wall of the silo, which will form a horizontal obstruction. Therefore, the binding height of each layer of horizontal steel bars cannot exceed the jack on the scissor frame, otherwise it cannot go up, resulting in the inability to fully expand the working surface. Only 30-50cm high steel bars can be tied each time. After exceeding the height, the newly tied steel bars will block the scissor frame and make it unable to lift. Therefore, during the construction process, after each upward slide of 30cm, a large number of manpower needs to be organized to start binding the steel bars and other operations required for the next slide of 30cm. The time interval is about 4 hours, resulting in low construction efficiency.

[0004] Therefore, how to improve the construction efficiency of building concrete silos is a technical problem that technical personnel in this field currently need to solve. Summary of the invention

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0050] like Figure 1-Figure 10 As shown, the concrete silo climbing rail sliding formwork system disclosed in the present invention includes a platform device, a crossbeam 200, a triangular support 300, a docking support 400, a formwork back support 500, a power unit 600, a track 700, a formwork body 800 and a wall attachment assembly 900, wherein the triangular support 300 includes a support 301, a hanging hole 302 and a connecting plate 303, the connecting plate 303 is used to clamp the track 700, the hanging hole 302 is used to connect the power unit 600, when the power unit 600 is in the second working state, the power unit 600 can drive the track 700 to move in the vertical direction, the crossbeam 200 is used to support the platform device, and the crossbeam 200 is fixedly connected to the support 301, and the triangular support 303 is used to connect the power unit 600. The bottom of 00 is connected to the top of the docking support 400, and the docking support 400 is arranged with two or more connecting plates 303 for clamping the track 700. The formwork back support 500 is fixedly connected to the beam 200, and the formwork back support 500 is used to fix the formwork body 800, and the formwork body 800 is used to form a concrete wall. When the power unit 600 is in the first working state, the power unit 600 can drive the beam 200, the triangular support 300, the formwork back support 500, the formwork body 800 and the platform device to move in the vertical direction. The wall attachment component 900 is fixed on the concrete wall and connected to the track 700. The triangular support 300, the track 700 and the power unit 600 are arranged in parallel.

[0051] Specifically, the triangular support 300 is made of two channel steels welded back to back, and the triangular support 300 has four relatively arranged supports 301 in the horizontal direction. The supports 301 are used to support the ends of the beam 200. The supports 301 and the beam 200 are welded or bolted, and the bottom of the triangular support 300 is bolted to the top of the docking support 400.

[0052] Specifically, the position of the connection plate 303 arranged on the docking support 400 is adapted to the position of the wall-mounted component 900 , and the connection plate 303 arranged on the docking support 400 can be connected to the wall-mounted component 900 when necessary.

[0053] Specifically, the concrete silo climbing rail sliding formwork system provided by the present invention, during the initial construction, first uses the formwork body 800 to cast a concrete wall with the same height as the formwork body 800, and the preferred casting height is 1.2 meters. During this casting process, there is no need to use devices such as triangular supports 300 and tracks 700. When casting a concrete wall of this height, a layer of wall-attached components 900 is pre-buried along the length direction of the wall according to the spacing between two parallel tracks 700, and then the formwork body 800 is removed, the track 700 is installed on the wall-attached components 900, and then the triangular supports 300 and other devices are installed. After the installation is completed, sliding formwork construction can be carried out.

[0054] Specifically, the above-mentioned concrete silo climbing rail sliding formwork system is arranged on both the inner and outer sides of the concrete wall, and the positions of the rails 700 correspond to each other. The rails 700 on the inner and outer sides of the concrete wall are temporarily connected using tension bolts to form a group of stable bodies.

[0055] Specifically, the bottom of the triangle support 300 is connected to the top of the docking support 400 , and the total height of the triangle support 300 and the docking support 400 is adapted to the length of the track 700 .

[0056] It should be noted that the total height of the concrete silo is usually 40 meters, and the track 700 does not need to be set at the full height. The preferred height of the track 700 is 6 meters. During the process of raising the slipform, when the lower concrete wall is formed, the newly added wall-mounted component 900 is connected to the wall, and the track 700 can automatically rise and continue to be used under the drive of the power unit 600, thereby saving production costs.

[0057] It should be noted that the slipform system slides up and down simultaneously inside and outside the preset concrete wall, does not occupy the internal space of the concrete silo, and reserves prefabricated space for other structural components inside the silo, such as the internal steel structure dome of the LNG storage tank. Therefore, the prefabrication of other structural components inside the silo can be carried out simultaneously with the construction of the slipform system, so as to further improve the overall construction efficiency of the silo.

[0058] It should be noted that the present invention adopts the track 700 attached to the wall of the silo as the load-bearing component of the platform device, and eliminates the support rod, the central control disc and the open frame. In this way, the steel bar binding above the casting surface will not be blocked, and the operating space on the ground inside the silo will not be occupied, so that the internal and external structures of the silo can be constructed simultaneously.

[0059] It should be noted that the concrete silo climbing rail sliding formwork system provided by the present invention can be applied to the construction of cylindrical cast-in-place concrete structures such as LNG outer tanks, chimneys, granaries, coal bunkers, etc.

[0060] The concrete silo climbing rail sliding formwork system provided by the present invention, when in use, first uses the formwork body 800 to cast a part of the concrete wall, and pre-buries two sets of wall-attached components 900 arranged relatively in the vertical direction on the concrete wall, and fixes two tracks 700 to the two sets of wall-attached components 900 respectively, connects the triangular support 300 and the power unit 600 to the track 700, the triangular support 300, the power unit 600 and the track 700 are related and can slide up and down, and the platform device falls on the beam 200 for workers to construct, and the power unit 600 is in the first working state When the power unit 600 drives the triangular support 300 to slide up multiple times to complete the sliding form construction of multiple strokes, the sliding height of the power unit 600 is adjustable. When the cumulative sliding height is the same as the height of the formwork body 800, the second layer of relatively arranged wall attachment components 900 can be pre-embedded in the concrete below the formwork body 800. When the top of the triangular support 300 rises to the same level as the top of the track 700, it can no longer continue to rise, and it is necessary to suspend the sliding formwork rising construction, so that the power unit 600 is in the second working state, and the track 700 climbing operation is performed to raise the track 700. In the above process, when the power unit 600 is in the first working state, the driving beam 200 slides upward, and the sliding height of the sliding form system can be adjusted. When the power unit 600 is in the second working state, the driving track 700 climbs upward to extend the upward construction height. Because the concrete silo climbing rail sliding form system provided by the present invention does not block the crossbeam 200, it is possible to tie more than 2 meters of steel bars at one time to make a working surface, thereby improving the construction efficiency of the concrete silo. By embedding the wall-attached component 900 and sliding upward at the same time, the slipform system can be continuously lifted and uninterrupted operation can be achieved, thereby improving the construction efficiency of the concrete silo.

[0061] In order to optimize the above technical solution, the platform device includes a main platform 101, an upper platform 100 and a lower platform 102. The main platform 101 is fixedly connected to the cross beam 200. The main platform 101, the upper platform 100 and the lower platform 102 are paved with steel plates, and the upper platform 100 is arranged above the main platform 101. The upper platform 100 includes a railing perpendicular to the steel plate, and the lower platform 102 is suspended from the cross beam 200. Specifically, the railing is preferably 1.5 meters to prevent people from falling and improve the safety of the platform device. The operator can stand on the steel plate to work. The main platform 101 and the cross beam 200 are welded or bolted, and the lower platform 102 is hung on the cross beam 200 by welding or bolting. When the number of the lower platforms 102 is two or more, the lower platform 102 at the lower position is hung and fixed on the lower platform 102 at the upper position. The main platform 101, the upper platform 100 and the lower platform 102 have the same function. When in use, the operator stands on the steel plate to perform operations, and the railings can ensure the safety of the operator. The number of lower platforms 102 can be increased according to usage needs to complete construction at different locations, thereby improving the construction efficiency of the concrete silo.

[0062] When in use, the operator on the upper platform 100 can perform tasks such as steel bar binding, the operator on the main platform 101 can perform tasks such as slipform pouring concrete, and the operator on the lower platform 102 can repair the appearance quality of the structure and install and disassemble the wall-mounted components 900. Multiple operations do not interfere with each other and are carried out simultaneously, which reduces the amount of labor invested at one time, saves manpower, and greatly improves the construction efficiency of building concrete silos.

[0063] It should be noted that the concrete silo climbing rail sliding formwork system provided by the present invention is used to manufacture a concrete silo with a total height of 40 meters. The sliding formwork construction cycle can reach 1.8 meters per day, and the sliding formwork construction can be completed in 25 days. Compared with the 120-day turnover formwork construction cycle, the construction efficiency of the concrete silo is greatly improved.

[0064] In order to optimize the above technical solution, there are two cross beams 200, which are arranged relatively at the top of the triangular support 300. The cross beam 200 includes a first mounting plate 201, a rib plate 202 and a pad 203. The formwork back support 500 is arranged with a first mounting seam 501 and a second mounting plate 502. The rib plate 202 is plugged into the first mounting seam 501, the first mounting plate 201 is connected to the second mounting plate 502, and the pad 203 is arranged between the first mounting plate 201 and the second mounting plate 502.

[0065] Specifically, the crossbeam 200 is an I-beam with bolt holes arranged at both ends for welding or bolting with the triangular support 300. The first mounting plate 201 is connected to the second mounting plate 502 by bolts. There are multiple rib plates 202, corresponding to the number of the template bodies 800.

[0066] Specifically, the pad 203 is arranged between the first mounting plate 201 and the second mounting plate 502. By adjusting the thickness of the pad 203, the depth of the rib plate 202 inserted into the first mounting seam 501 can be adjusted, thereby adjusting the distance between the beam 200 and the formwork back support 500. The slipform system is used on a curved wall. The distance between the beam 200 and the formwork back support 500 can be changed by adjusting the thickness of the pad 203, thereby adjusting the curvature of the formwork back support 500.

[0067] Specifically, the concrete silo is a cylindrical structure, that is, the concrete wall is in the shape of an arc. When in use, a plurality of triangular supports 300 are evenly arranged around the concrete wall. There is an arc between two adjacent triangular supports 300, and the beam 200 arranged on the triangular support 300 is equivalent to the chord length. The operator only needs to adjust the relative position of the beam 200 and the support 301 to meet the assembly needs of various arcs, so that the beams 200 with the same length can be used for the assembly needs of various arcs at the same time, and there is no need to process beams 200 of different sizes, thereby saving production costs.

[0068] In order to optimize the above technical solution, the connecting plate 303 is provided with symmetrical slots, which are used to clamp the track 700. The end of the connecting plate 303 is provided with a first mounting hole 304, and the wall-mounted component 900 is provided with a second mounting hole 901. The wall-mounted component 900 includes a first pin, which passes through the first mounting hole 304 and the second mounting hole 901, and is used to fix the wall-mounted component 900 and the connecting plate 303. Specifically, the connecting plate 303 is composed of two pieces, which are arranged relative to each other. When the top of the triangular support 300 rises to be flush with the top of the track 700, the platform device can no longer continue to rise, and it is necessary to suspend the sliding construction and perform the track 700 climbing operation to raise the track 700. At this time, it is necessary to first fix the connecting plate 303 and the wall-mounted component 900 with the first pin, so that the triangular support 300 and the docking support 400 are fixed to the concrete wall and cannot move up and down, and then the power unit 600 drives the track 700 to climb in the vertical direction. This arrangement allows the length of the track 700 to be any size and does not need to be at the same height as the concrete silo structure, thereby saving production costs.

[0069] In order to optimize the above technical solution, the butt support 400 further includes two top screws 401 arranged opposite to each other, and the ends of the top screws 401 abut against the concrete wall. Specifically, the triangular support 300 and the butt support 400 are fixedly connected to form a whole, and rotating the top screw 401 can make the whole connected by the triangular support 300 and the butt support 400 press against the concrete wall, thereby adjusting the verticality of the whole and the track 700. During the slipform process, the top screw 401 is used to adjust the verticality, which makes it easier to control the quality of the finished surface of the concrete silo structure, so as to improve the construction efficiency of the concrete silo.

[0070] In order to optimize the above technical solution, the template back support 500 also includes a second installation seam 503, the template body 800 includes a keel 801, the second installation seam 503 is arranged opposite to the first installation seam 501, and the second installation seam 503 is plugged into the keel 801.

[0071] Specifically, the template back support 500 is made by back-to-back welding of angle steels, and a gap is left, namely a first installation gap 501 and a second installation gap 503 .

[0072] Specifically, the formwork back support 500 is composed of a plurality of inverted triangle-shaped steel frames, each of which is made of angle steel, and the formwork back support 500 is hung upside down at the bottom of the beam 200 .

[0073] Specifically, the template body 800 is made of steel plate or aluminum alloy, and the keel 801 on the back thereof protrudes from the template body 800 .

[0074] Specifically, the keel 801 preferably protrudes 5 cm from the four sides of the template body 800 and extends 10 cm downward.

[0075] Specifically, the formwork back support 500 is hung upside down on the beam 200 and does not occupy the space above the main platform 101, so that the slipform system can slide upward from a lower position, thereby improving the construction efficiency of building a concrete silo. The top of the triangular support 300 extends upward, and a hanging hole 302 is provided at the end for hanging the upper reversing box 601 described below, so that the height of the main platform 101 during the initial installation can be lower, and the slipform system can further slide upward from a lower position, thereby further improving the construction efficiency of building a concrete silo.

[0076] In order to optimize the above technical solution, the power unit 600 includes an upper reversing box 601, a cylinder 602 and a lower reversing box 603. The upper reversing box 601 is connected to the hanging hole 302, the lower reversing box 603 is connected to the track 700, and the two ends of the cylinder 602 are respectively connected to the upper reversing box 601 and the lower reversing box 603. When the power unit 600 is in the first working state, the lower reversing box 603 is fixedly connected to the track 700, the upper reversing box 601 is slidably connected to the track 700, the triangular support 300 is fixedly connected to the upper reversing box 601, and the track 700 is fixedly connected to the wall-mounted component 900. When the power unit 600 is in the second working state, the lower reversing box 603 is fixedly connected to the track 700, the upper reversing box 601 is slidably connected to the track 700, the triangular support 300 is fixedly connected to the concrete wall, and the track 700 is disconnected from the wall-mounted component 900.

[0077] Specifically, the upper reversing box 601 is connected to the hanging hole 302 by a second pin shaft, and the oil cylinder 602 is a hydraulic cylinder, and the extension and contraction of the hydraulic cylinder is used to control the relative movement of the triangular support 300 and the track 700. The upper reversing box 601 and the lower reversing box 603 are both arranged with a slot structure to move up and down along the track 700, and the upper reversing box 601 and the lower reversing box 603 are both arranged with a reversing mechanism inside to fix or disengage from the track 700.

[0078] Specifically, the connection point where the upper reversing box 601 is fixedly connected to the top of the triangular support 300 is not detachable and is always in a connected state.

[0079] When in use, initially, the lower reversing box 603 is fixedly connected to the track 700, the cylinder 602 is extended, and the sliding formwork system composed of the upper reversing box 601, the triangular support 300, the crossbeam 200, the formwork back support 500, the formwork body 800 and the platform device slowly slides upward to complete a stroke of sliding formwork construction. After reaching the preset position, the upper reversing box 601 is fixedly connected to the track 700, the fixed connection between the lower reversing box 603 and the track 700 is disconnected, the cylinder 602 contracts, the lower reversing box 603 rises, and the cylinder 602 is reset to prepare for the next sliding. The above process is the first working state of the power unit 600. The above process is repeated to realize the continuous rise of the sliding formwork system.

[0080] Specifically, the height of each sliding can be adjusted according to the needs of use, preferably 0.3 meters. When the cumulative sliding height reaches a position that is an integer multiple of the height of the template body 800, the top of the triangular support 300 rises to be flush with the top of the track 700, and the sliding construction needs to be suspended to perform the track 700 climbing operation. First, the connecting plate 303 and the wall-mounted assembly 900 are fixed with the first pin shaft, so that the triangular support 300 and the docking support 400 are fixed to the concrete wall and cannot move up and down, the upper reversing box 601 is disconnected from the track 700, the lower reversing box 603 is fixedly connected to the track 700, the track 700 is disconnected from the wall-mounted assembly 900, and the oil cylinder 602 contracts, driving the lower reversing box 603 and the track 700 to climb upward. The above process is the second working state of the power unit 600.

[0081] Furthermore, when the cumulative sliding height reaches a position that is an integer multiple of the height of the formwork body 800, the second layer of wall-attached components 900 are embedded in the next pouring of concrete. When the sliding formwork system continues to slide upward and the second layer of wall-attached components 900 are exposed, the second layer of wall-attached components 900 are connected to the track 700, and the docking support 400 is connected to the triangular support 300 to extend it into a whole. Multiple lower platforms 102 are hung in turn under the beam 200 to complete the assembly of the sliding formwork system again.

[0082] By arranging the upper reversing box 601, the oil cylinder 602 and the lower reversing box 603, free switching between the sliding of the sliding form system and the sliding of the track 700 is achieved, thereby further improving the construction efficiency of the concrete silo.

[0083] Furthermore, after the concrete wall work is completed, the rails 700 can be completely pulled out using a tower crane to complete the disassembly, and the other components of the slipform system can be dismantled in reverse order according to the order of installation.

[0084] In order to optimize the above technical solution, the template backing 500 also includes three pin holes 504 arranged vertically, and the keel 801 is provided with three round holes 802 matching the three pin holes 504, and the pin holes 504 are connected to the round holes 802 by pins. Specifically, the template body 800 is assembled in blocks, and two adjacent template bodies 800 are connected by pins. The width of a single template body 800 is the same as the distance between two adjacent template backings 500, and a single template body 800 is connected to a single template backing 500 separately.

[0085] During use, when it is necessary to lift the formwork body 800 and the concrete wall but not completely remove the formwork body 800, it is only necessary to pull out the pins of the two upper round holes 802, retain the lower pin, and use the lower pin as the axis to pry the formwork body 800 outwards to complete incomplete demolding. The operation process is simple and the problem of demolding and cleaning required when the sliding form stops is avoided.

[0086] In order to optimize the above technical solution, the first side of the track 700 close to the concrete wall is connected to the wall attachment component 900, and the second side of the track 700 away from the concrete wall is connected to the power unit 600. A clamping piece is arranged on the second side of the track 700, and the clamping piece is used to clamp the power unit 600. Specifically, the clamping piece is used to clamp the upper reversing box 601 and / or the lower reversing box 603, and the clamping form of the clamping piece includes but is not limited to plugging, abutting, etc. Specifically, the wall attachment component 900 is fixed to the concrete wall through the bolt cone head embedded in the concrete, and is connected to the track 700 by a third pin or bolt. By arranging the clamping piece, the upper reversing box 601 and / or the lower reversing box 603 can be limited to further improve the stability and reliability of the concrete silo climbing rail sliding formwork system.

[0087] In order to optimize the above technical solution, the end of the keel 801 is arranged with a chamfer. Specifically, the chamfer is preferably a circular chamfer. During the incomplete demolding process, the circular chamfer can ensure that the keel 801 will not scratch the surface of the concrete wall to protect the concrete wall. Specifically, the incomplete demolding process is suitable for situations where the sliding has to be stopped due to extreme weather during the sliding formwork construction. There is no need to completely remove the formwork body 800. When it needs to be reinstalled, the sliding formwork construction can be resumed, thereby further improving the construction efficiency of the concrete silo.

[0088] The advantages of the present invention are:

[0089] (1) Improved the construction efficiency of concrete silos;

[0090] (2) High safety: After installation, it will automatically climb up through hydraulic power, and the whole will be connected together and attached to the wall through rails;

[0091] (3) A slipform structure with tracks arranged on the outside of the concrete cylinder wall is used. There is no obstruction above the working surface inside the concrete wall. The steel bars, embedded parts, etc. above the casting surface can be cross-constructed in the same way as normal construction structure procedures. The 3-6m steel bar binding working surface can be completed at one time to create working space for the slipform;

[0092] (4) Use external rails and docking supports to control the verticality of the cylinder wall. The rigidity of the rails is higher than the strength of the internal support rods of the traditional sliding formwork structure, so the formwork is not easily torsionally deformed. At the same time, the verticality can be adjusted by the top screw during the sliding formwork process, making it easier to control the quality of the finished surface of the structure;

[0093] (5) Save manpower and production costs;

[0094] (6) High stability, the sliding mode system structure is safe and reliable.
