Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a hydraulic self-climbing elevator shaft standardized operating platform and a construction method. Background Art

[0002] In construction, we often encounter cylinder-type cast-in-place shear walls of various shapes and different cross-sectional sizes, such as elevator shaft-type cast-in-place shear walls. When constructing such cast-in-place shear walls, we usually overlap the formwork platform inside the cylinder and then install the formwork. The more common method is to use steel pipes, fasteners, wooden squares, plywood and other materials to assemble and cast the cast-in-place shear wall forming formwork.

[0003] Traditional splicing construction methods like the one above consume a lot of materials, are labor-intensive and time-consuming, and cast-in-place shear walls of different shapes and cross-sectional sizes require splicing parts of different specifications and quantities. Not only is the construction cost high and the workload heavy, but the simple platforms constructed also pose great safety hazards.

[0004] Therefore, some construction units have adopted the integral self-climbing drum formwork. However, the conventional integral self-climbing drum formwork generally only uses a transmission device on the climbing part. The demoulding and fixing operations of the formwork are still done manually, the construction efficiency is still low, and the construction of large-scale formwork still has great safety hazards. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a hydraulic self-climbing elevator shaft standardization operation platform and construction method to solve the problem that in the existing integral self-climbing cylinder mold, the demoulding and fixing and positioning operations of the template are mostly done manually, and the construction efficiency is still low.

[0006] In order to achieve the above-mentioned object, the basic scheme of the present invention is as follows: a hydraulic self-climbing elevator shaft standardized operating platform, comprising:

[0007] A first climbing component capable of abutting against the inner wall of a cylindrical cast-in-place shear wall;

[0008] A second climbing component can be abutted against the inner wall of the cylindrical cast-in-place shear wall, the lower end of the second climbing component is located on the upper side of the lower end of the first climbing component, and a mounting hole for a part of the first climbing component to pass through is provided in the middle of the second climbing component;

[0009] A power device for controlling the staggered climbing of the first climbing assembly and the second climbing assembly, the power device being fixedly connected to the first climbing assembly or the second climbing assembly;

[0010] Steel frame support, the steel frame support is adjustably mounted on the second climbing assembly;

[0011] Formwork assembly, the formwork assembly can be detachably installed on the steel frame support;

[0012] A plurality of pull-up adjustment support units are provided, one end of the pull-up adjustment support unit is hinged to the template assembly, and the other end of the pull-up adjustment support unit is hinged to one end of the first climbing assembly passing through the second climbing assembly.

[0013] The technical principle of the present invention is: when the hydraulic self-climbing elevator shaft standardized operating platform is in use, the first climbing component and the second climbing component can both be against the inner wall of the cast-in-place shear wall, so that after being fixed, they can cooperate with the formwork component to cast the upper cast-in-place shear wall; after the casting is completed, the power device can cooperate with the first climbing component and the second climbing component, so that the first climbing component and the second climbing component can climb alternately. When the first climbing component and the second climbing component climb alternately, the installation hole can cooperate with the local part of the first climbing component, so that the first climbing component or the second climbing component can be stably guided and limited by each other when climbing, so that the climbing of the first climbing component and the second climbing component is stable and the climbing efficiency is high.

[0014] When the supporting formwork assembly is used to cast the upper cast-in-place shear wall, the steel skeleton support and the upward-adjustable support unit can provide stable support for the supporting formwork assembly, so that the upper cast-in-place shear wall remains stable during casting and the upper cast-in-place shear wall is precisely formed; because the steel skeleton support is adjustably installed on the second climbing assembly and cooperates with the upward-adjustable support unit, the disassembly and assembly of the formwork assembly is more convenient and efficient when the formwork assembly is folded or unfolded.

[0015] Further, the first climbing assembly comprises:

[0016] Beam frame, the beam frame is set horizontally;

[0017] A first adjusting slide group, the first adjusting slide group is horizontally installed on the end of the beam frame;

[0018] A first latch foot, the first latch foot is hinged and horizontally adjustable and installed on an end of the first adjustment slide away from the beam frame;

[0019] A first tension spring, one end of the first tension spring is connected to the first latch foot, the other end of the first tension spring is connected to the first latch foot and connected to an end of the first adjustment slide group away from the beam frame, and the hinge between the first latch foot and the first adjustment slide group is located between the first tension springs;

[0020] The column is vertically installed on the upper side of the beam frame, the column can pass through the installation hole and is hinged with the upward pull adjustment support unit, and the power device is installed on the column or the second climbing component.

[0021] With the above settings, the beam frame can stably support the first latch leg and the column. When installing the first climbing component into the elevator shaft, first adjust the position of the first adjustment slide group on the end of the beam frame according to the size of the elevator shaft, so that the first latch leg can be clamped and supported at the lower cast-in-place shear wall. When the first climbing component needs to climb, control the first tension spring to fold the first latch leg, so that the first latch leg can be disengaged from the lower cast-in-place shear wall and climb upward under the control of the power device and the guidance of the column. When the first climbing component climbs, the cooperation between the various structures is precise and stable, and it is convenient to adapt to elevator shafts of different sizes.

[0022] Furthermore, the second climbing component includes:

[0023] A cross beam, the cross beam is in a "well" shape, the power device is installed on the cross beam, and the installation hole is located in the middle of the cross beam;

[0024] A guide rail group, the guide rail group is horizontally and fixedly installed on the end of the cross beam;

[0025] A slider that can slide along the guide rail group;

[0026] A support plate, the support plate is horizontally and fixedly installed on the slider;

[0027] A second adjustment slide group, the second adjustment slide group is horizontally installed on the end of the cross beam, and the second adjustment slide group and the support plate are located on different ends of the cross beam;

[0028] A second latch leg, the second latch leg is hinged and horizontally adjustable and installed on the end of the second adjustment slide group away from the cross beam;

[0029] A second tension spring, one end of the second tension spring is connected to the second latch leg, the other end of the second tension spring is connected to the end of the second adjustment slide group away from the cross beam where the second latch leg is connected, and the hinge point between the second latch leg and the second adjustment slide group is located between the second tension springs;

[0030] A number of connecting beam units, one end of the connecting beam unit is fixedly connected to the slider on one of the guide rail groups, the other end of the connecting beam is fixedly connected to the slider on the other guide rail group, and the steel skeleton support is installed on the connecting beam unit and the support plate;

[0031] A hydraulic cylinder, the hydraulic cylinder is horizontally installed between the support plate and the cross beam or between the connecting beam unit and the cross beam, and the axis of the hydraulic cylinder is parallel to the axis of the guide rail group.

[0032] Through the above arrangement, the crossbeam can stably support structures such as the second latch foot, the connecting beam unit, the second adjustment slide group and the support plate; when the second climbing component is installed in the elevator shaft, the position of the second adjustment slide group on the end of the beam frame is first adjusted according to the size of the elevator shaft, so that the second latch foot can be embedded and supported to the lower cast-in-place shear wall. When the second climbing component needs to climb, the second tension spring is controlled to fold the second latch foot, so that the second latch foot can be separated from the lower cast-in-place shear wall and climb upward under the control of the power device and the guidance of the column. When the second climbing component climbs, the various structures still cooperate accurately and stably, and it is easy to adapt to elevator shafts of different sizes; when pouring the cast-in-place shear wall, the connecting beam unit and the support plate can cooperate with the guide rail group and the slider, so that the installation position of the steel skeleton support is easy to control and stably supported, and the formwork component can be stably supported, and the position of the formwork component is also easy to control, making the disassembly and assembly of the formwork component more convenient.

[0033] Furthermore, the second climbing assembly also includes a plurality of limit slider groups, which are installed on the middle inner wall of the beam, and the limit slider groups are in sliding contact with the outer wall of the column.

[0034] Through the above arrangement, the limit slider group can limit the column, so that when the column slides relative to the mounting hole, the lifting and lowering of the column is more stable, and the climbing of the first climbing component or the second climbing component is also smoother and more stable.

[0035] Furthermore, the power unit comprises:

[0036] A rack, the rack is fixedly mounted on the outer wall of the column, and the axis of the rack is parallel to the vertical axis of the column;

[0037] a gear meshing with a rack;

[0038] The first motor controls the rotation of the gear, and the first motor is fixedly installed at the middle part of the crossbeam.

[0039] Through the above arrangement, when the first climbing assembly and the second climbing assembly are allowed to climb alternately, it is only necessary to control the first latch foot or the second latch foot to be in a state of abutting against the cast-in-place shear wall, and then start the first motor to control the rack to move upward or control the gear to move upward relative to the rack, thereby controlling the first climbing assembly or the second climbing assembly to climb. The switching of the climbing states of the first climbing assembly and the second climbing assembly is convenient and efficient, and the power transmission for climbing is also very efficient.

[0040] Furthermore, the number of the support plates is two, and the two support plates are symmetrically arranged along the crossbeam; the number of the connecting beam units is two, and the two connecting beam units are symmetrically arranged along the crossbeam.

[0041] Through the above arrangement, the support plate and the connecting beam unit can stably support the steel frame, and make the force at the end of the beam more balanced. When controlling the position of the support plate and the connecting beam unit, the control of the hydraulic cylinder is also more balanced.

[0042] Furthermore, the number of steel frame supports is four, and the steel frame supports are vertically and detachably mounted on the support plate or the connecting beam unit.

[0043] Through the above arrangement, the steel skeleton supports correspond one-to-one with the two support plates and the two connecting beam units, so that the four steel skeleton supports can be supported evenly and stably, and the four steel skeleton supports can be driven to fold or extend, thereby facilitating the disassembly and assembly of the formwork assembly.

[0044] Further, the template components include:

[0045] Four straight templates, the four straight templates correspond to the four steel frame supports one by one and are detachably connected, wherein two of the straight templates are fixedly provided with a latching mold located on the same vertical plane as the first latching foot or the first latching foot on one side away from the column;

[0046] A first oblique mold, the first oblique mold is assembled and installed on one side of the vertical edge of the straight template;

[0049] An adjusting bolt group is installed between the first oblique die, the angle die and the second oblique die.

[0050] Through the above-mentioned arrangement, when the straight formwork, the first oblique formwork, the angle formwork, the second oblique formwork and the adjusting bolt group in the formwork assembly are disassembled and assembled, the angle formwork can be installed in cooperation with the first oblique formwork or the second oblique formwork at the edge of the straight formwork; when the formwork assembly is installed at the casting cavity, the angle formwork only needs to be disassembled and assembled with the adjusting bolt group at the first oblique formwork or the second oblique formwork, thereby realizing the rapid disassembly and assembly of the formwork assembly; when the straight formwork, the first oblique formwork, the angle formwork and the second oblique formwork in the formwork assembly are folded or unfolded under the drive of the steel skeleton support and the upward pull-up adjustment support unit, the first oblique formwork, the angle formwork and the second oblique formwork are not easy to interfere with each other, so that the folding or unfolding of the formwork assembly is more stable and reliable.

[0051] Furthermore, a power assembly is also included, and the power assembly includes:

[0052] A capstan, wherein an arc-shaped slot is vertically provided on the capstan, one end of the slot extends toward the axis of the capstan, and the other end of the slot extends toward the edge of the capstan;

[0054] A second motor drives the drive source shaft to rotate forward and reversely, the second motor is fixedly mounted on the upper end of the column, and the drive source shaft is coaxially arranged with the column;

[0055] A fixing plate, the fixing plate is fixedly mounted on the upper end of the column, and the fixing plate is located between the second motor and the winch;

[0061] The handle is fixedly mounted on the outer wall of the sleeve.

[0062] Through the above arrangement, when the formwork assembly is separated from the cast-in-place shear wall, the second motor is started, the second motor drives the driving source shaft and the winch to rotate, and the winch drives the end of the pull rod to slide along the winch's slot toward the center of the winch, so that the pull rod shrinks into the winch, and the formwork assembly can be folded along the arc of the slot, so that the first oblique mold, the angle mold, and the second oblique mold are not easy to interfere with each other when folded or unfolded.

After the straight formworks are assembled with the first oblique formwork, the angle formwork and the second oblique formwork, a casting cavity for the cast-in-place shear wall is formed between the outer wall of the formwork assembly and the inner wall of the elevator shaft; install the formwork assembly on the pull-up adjustment support unit and the steel skeleton support;

[0067] Step 4: According to the length and width of the elevator shaft cross-sectional profile, adjust the length of the pull-up adjustment support unit and the hydraulic cylinder so that the outer wall of the formwork assembly can be located at the inner wall of the casting cavity, the lower side of the formwork assembly fits with the outer wall of the lowest cast-in-place shear wall, the upper outer wall of the formwork assembly and the inner wall of the elevator shaft form a casting cavity, and concrete is poured into the casting cavity to form a middle-layer cast-in-place shear wall;

[0068] Step 6: After the middle-layer cast-in-place shear wall is cured and formed, the connection between the formwork components is disassembled, and the power component and the hydraulic cylinder are started. The power component drives the upward pull-adjustable support unit to rotate and retract toward the column. The hydraulic cylinder retracts, and the upward pull-adjustable support unit and the steel skeleton support drive the formwork component to detach from the middle-layer cast-in-place shear wall.

[0069] Step 7: The first motor controls the gear to rotate in the opposite direction, the second tension spring pulls the second latch foot to retract, and the second latch foot is disengaged from the latch groove; the gear moves upward relative to the rack under the support of the rack, the second climbing assembly moves upward along the column as a whole, and the upward adjustment support unit rotates relative to the power assembly and the formwork assembly to an inclined state; after the second climbing assembly climbs to the desired position, the second tension spring is relaxed, the second latch foot is embedded in the side wall of the middle-layer cast-in-place shear wall to form a latch groove again, and the second climbing assembly completes the climbing positioning;

[0071] Repeat steps 4-8 to cast and cure the upper middle layer of cast-in-place shear wall until the cast-in-place shear wall inside the cylinder is completely formed.

[0072] The technical principle of the present invention is as follows: during operation, this construction method adopts a hydraulic self-climbing elevator shaft standardized operating platform to allow the middle-level cast-in-place shear wall to be formed in sections during the staggered climbing of the first climbing component and the second climbing component; during the formation process, the formwork component can be stably stretched and supported or stably supported and stretched, which is convenient for the precise forming of the middle-level cast-in-place shear wall; at the same time, the latch mold can form a latch groove on the cast-in-place shear wall, and the latch groove can cooperate with the first latch foot and the second latch foot, thereby providing a stable and precise support position for the staggered climbing of the first climbing component and the second climbing component and the segmented forming of the cast-in-place shear wall, so that the cast-in-place shear wall can be accurately and quickly formed; during the entire construction process, there is less manual participation, which can improve construction efficiency and reduce construction difficulty.

[0091] Step 1: In the initial state, the bottom cast-in-place shear wall 9 is manually pre-constructed at the bottom of the elevator shaft;

[0092] Step 2: Install the hydraulic self-climbing elevator shaft standardization operating platform to the bottom of the elevator shaft, fit the upper side of the beam frame 12 with the lower side of the crossbeam 21, adjust the position of the first adjustment slide 13 on the beam frame 12, so that the first latch foot 15 on the end of the first adjustment slide 13 abuts against the outer wall of the bottom cast-in-place shear wall 9 and can be located at the latch groove formed by the outer latch mold 66 of the template assembly 6 after abutting against each other. After reaching the required position, the first adjustment hole 113 on the first adjustment slide 13 coincides with the second adjustment hole 112 on the beam frame 12 and is locked with the first bolt group 14; at the same time, adjust the crossbeam The second adjusting slide 22 on the part 21 is positioned so that the second latch foot 24 on the end of the second adjusting slide 22 abuts against the outer wall of the bottom cast-in-place shear wall 9 and can be located at the latch groove formed by the latch mold 66 of the template assembly 6 after the abutment. After reaching the required position, the third adjusting hole 212 on the second adjusting slide 22 coincides with the fourth adjusting hole on the beam frame 12 and is locked with the second bolt group 23, so as to adapt to the construction of elevator shafts of different specifications; after the hydraulic self-climbing elevator shaft standardized operating platform is installed, the first latch foot 15 and the second latch foot 24 are embedded in the latch groove formed by the latch mold 66;

[0093] Step 3: According to the length and width of the elevator shaft cross-sectional profile, four straight templates 61 of corresponding width are selected, and the straight template 61 is assembled with the first oblique mold 62, the angle mold 63 and the second oblique mold 64 as shown in FIG. Figure 5 As shown, the formwork assembly 6 is installed on the pull-up adjustment support unit 8 and the steel skeleton support 5, the gripping handle 84 is rotated around the axis of the sleeve 83, and the bolts on both ends of the sleeve 83 are rotated relative to the screw rod 81, thereby adjusting the length of the single pull-up adjustment support unit 8, and then adjusting the horizontal position of the single straight formwork 61, so that the outer wall of the entire formwork assembly 6 can form a casting cavity for the cast-in-place shear wall 9 between the inner wall of the elevator shaft, so as to adapt to the inner wall position of different elevator shafts;

[0094] Step 4: According to the length and width of the elevator shaft cross-sectional profile, adjust the length of the pull-up adjustment support unit 8, the power assembly 7 and the hydraulic cylinder 28 so that the outer wall of the template assembly 6 can be located at the inner wall of the casting cavity. At this time, adjust the bolt group 65 to fix the angle mold 63 and the first oblique mold 62 or the angle mold 63 and the second oblique mold 64 to realize the splicing of the template assembly 6; the lower side of the template assembly 6 is fitted with the outer wall of the bottom layer of the cast-in-place shear wall 9, and the upper outer wall of the template assembly 6 forms a casting cavity with the inner wall of the elevator shaft, and concrete is poured into the casting cavity to form the middle layer of the cast-in-place shear wall 9;

[0095] Step 6: After the middle-layer cast-in-place shear wall 9 is cured and formed, the adjusting bolt group 65 on one side of the angle mold 63 is removed to realize the disassembly of the formwork assembly 6, so as to prepare for the separation of the formwork assembly 6 from the middle-layer cast-in-place shear wall 9; the second motor 73 and the hydraulic cylinder 28 are started, and the second motor 73 drives the driving source shaft 72 and the winch 71 to rotate, and the winch 71 drives the end of the pull rod 75 to slide along the slot 711 of the winch 71 toward the center of the winch 71, so that the pull rod 75 is retracted into the winch 71, and at the same time, the hydraulic cylinder 28 is retracted, and the steel skeleton support 5 is controlled to be retracted toward the column 17 under the support of the connecting beam unit 3 or the support plate 29 through the guide rail group 25 and the slider 26, and then the upward pull adjustment support unit 8 and the steel skeleton support 5 synchronously drive the formwork assembly 6 as a whole to quickly separate from the middle-layer cast-in-place shear wall 9;

[0096] Step 7: The first motor 43 controls the gear 41 to rotate in the opposite direction, and the second tension spring 214 pulls the second latch foot 24 to retract, and the second latch foot 24 is disengaged from the latch groove; the gear 41 moves upward relative to the rack 42 under the support of the rack 42, and the second climbing component 2 moves upward along the column 17 as a whole, and the upward adjustment support unit 8 rotates to an inclined state relative to the power component 7 and the formwork component 6; after the second climbing component 2 climbs to the desired position, the second tension spring 214 is relaxed, and the second latch foot 24 is embedded in the side wall of the middle-layer cast-in-place shear wall 9 to form a latch groove again, and the second climbing component 2 completes the climbing positioning;

[0097] Step 8: The first motor 43 controls the gear 41 to rotate forward, the first tension spring 16 pulls the first latch foot 15 to retract, and the first latch foot 15 is out of the latch groove; the gear 41 drives the rack 42 to move upward, the first climbing assembly 1 moves upward along the column 17 as a whole, and the upward adjustment support unit 8 rotates relative to the power assembly 7 and the formwork assembly 6 to restore to a horizontal state; after the first climbing assembly 1 climbs to the desired position, the first tension spring 16 is relaxed, the first latch foot 15 is embedded in the side wall of the middle-layer cast-in-place shear wall 9 to form a latch groove again, and the first climbing assembly 1 completes the climbing positioning;

[0098] Repeat steps 4-8 to cast and cure the upper middle layer of cast-in-place shear wall 9 until the cast-in-place shear wall 9 inside the cylinder is completely formed.

[0099] The hydraulic self-climbing elevator shaft standardized operating platform in this embodiment can drive the first climbing component 1 and the second climbing component 2 to climb alternately when constructing the cast-in-place shear wall 9 under the cooperation of the rack 42 and the gear 41; when climbing, the column 17 of the first climbing component 1 can cooperate with the mounting hole and the limit slider 26 group on the second climbing component 2, so that the first climbing component 1 or the second climbing component 2 is stably guided and limited to each other when climbing, so that the climbing of the first climbing component 1 and the second climbing component 2 is stable and efficient; the first latch foot 15 cooperates with the first tension spring 16 and the second latch foot 24 can cooperate with the second tension spring 214, so as to facilitate the extension and contraction of the first latch foot 15 and the second latch foot 24, and then cooperate with the latch groove formed by the latch mold 66, so as to facilitate the first latch foot 15 and the second latch foot 24 to be stably supported on the formed cast-in-place shear wall 9, and provide stability for the climbing of the first climbing component 1 or the second climbing component 2 and the support of the template component 6.

[0100] When the straight formwork 61, the first bevel formwork 62, the angle formwork 63, the second bevel formwork 64 and the adjusting bolt group 65 in the formwork assembly 6 are disassembled and assembled, the angle formwork 63 can cooperate with the first bevel formwork 62 or the second bevel formwork 64 at the edge of the straight formwork 61 for installation. When the formwork assembly 6 is installed in the casting cavity, the angle formwork 63 only needs to be disassembled and assembled with the adjusting bolt group 65 at the first bevel formwork 62 or the second bevel formwork 64, thereby realizing rapid disassembly and assembly of the formwork assembly 6. It is also convenient to select and install the formwork assembly 6 according to the structure of the elevator shaft, and is convenient to stably install and cooperate with the pull-up adjustment support unit 8, thereby improving the adaptability of the entire hydraulic self-climbing elevator shaft standardized operating platform.

[0101] When the formwork assembly 6 is pushed and installed to the casting cavity and the formwork assembly 6 is separated from the cast-in-place shear wall 9, the hydraulic cylinder 28 can stably push the support plate 29 and the connecting beam unit 3 to move horizontally along the guide rail group 25, so that the lower end of the steel skeleton support 5 moves horizontally and stably; at the same time, the upper side of the straight formwork 61 moves synchronously under the control of the power assembly 7 and the upward pull-adjusting support unit 8, so that when the formwork assembly 6 is close to the casting cavity or separated from the cast-in-place shear wall 9, the formwork assembly 6 can be folded or unfolded along the arc of the slot 711, so that the first inclined mold 62, the angle mold 63, and the second inclined mold 64 are not easy to interfere with each other, and the movement of the upper and lower sides of the formwork assembly 6 is stable.

[0102] During the construction process, the first motor 43, the second motor 73 and the hydraulic cylinder 28 can be electrically controlled, so that the construction process of the cast-in-place shear wall 9 can be more automatically controlled and the construction efficiency can be improved.

[0103] The standardized operating platform and construction method of the hydraulic self-climbing elevator shaft in this embodiment can be more widely applied to elevator shaft structures of different sizes, and has strong versatility and professionalism.
