Description

Technical Field

[0001] The invention relates to the field of concrete floor slab construction, in particular to a heavy-duty slab construction machine. Background Art

[0002] For example, Chinese invention patent application publication number CN 106032705 A discloses an integrated casting and forming construction method for reinforced concrete floor slabs. This integrated casting and forming construction method for reinforced concrete floor slabs involves separately assembling a self-balancing integral structure of reinforced concrete beams and reinforced concrete floor slabs, hoisting the separately assembled self-balancing structures, and pouring concrete within the assembled floor slab self-balancing formwork structure to form an integrated cast reinforced concrete floor slab structure. The formwork generally relies on scaffolding for support. As the concrete floor slabs become larger in size, more scaffolding materials are consumed, and the construction period is also longer, which is not conducive to improving efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a heavy-duty cover slab construction machine, which is conducive to improving the construction efficiency of concrete floor slabs. During slipform construction, after the formwork is removed, it can be stacked in the overhead layer and can be moved perpendicular to the concrete beam to the next construction section. Compared with the slipform construction scheme that can only move along the concrete beam, it has a higher utilization rate and more flexible usage scenarios, and is suitable for the construction of heavy-duty cover slabs with larger specifications.

[0004] In order to achieve the above purpose, a heavy cover plate building machine is used, which includes:

[0005] The truss beams are arranged at intervals to form overhead layers between adjacent truss beams;

[0006] A U-shaped frame is provided between the truss beams, with its top surface lower than the top surface of the truss beams to reserve space for stacking formwork;

[0007] A portal support frame, which is slidably mounted on a U-shaped frame;

[0008] A hydraulic jack is installed on the U-shaped frame and fixes the top support portal support frame to drive the portal support frame to slide up and down along the U-shaped frame;

[0009] The guide wheel moving assembly is installed at the bottom of both ends of the truss beam; the guide wheel moving assembly can be equipped with a reduction motor to drive the movement, or a transverse jack can be installed on the track to push the truss beam as a whole, thereby achieving a sliding effect.

[0010] Tracks, which are laid under the guide wheel moving assembly;

[0011] A drop block, which is mounted on the bottom surface of the track;

[0012] a lattice column supporting the bottom surface of the drop block below one end of the truss beam;

[0013] Embedded corbels for structural columns are installed on the sides of the structural columns and supported on the bottom surface of the unloading block below the other end of the truss beam;

[0014] The detachable formwork assembly includes a beam bottom formwork installed on the truss beam, a beam side formwork installed on the side of the beam bottom formwork, a plate bottom formwork installed on the portal support frame, and a female angle formwork detachably connected between the beam side formwork and the plate bottom formwork.

[0015] With such a structure, the overhead layer can be used to stack the slab bottom formwork and beam side formwork; the hydraulic jack can drive the gantry support frame up and down, and the gantry support frame is used to fix the slab bottom formwork; the slab bottom formwork is spliced through the internal angle formwork and the beam side formwork, and after the limit of the slab bottom formwork and the internal angle formwork is released, the slab bottom formwork can be demoulded first by the hydraulic jack; after the beam side formwork and the internal angle formwork are removed, they can be stacked on the slab bottom formwork; the beam bottom formwork is fixed on the truss beam; after the slab bottom formwork, beam side formwork and internal angle formwork are placed, the unloading block is lowered so that the beam bottom formwork can be demoulded, so that the height of the formwork after the overall demoulding will still not be higher than the beam bottom elevation, and the whole can be slid along the width of the beam and moved to the next construction section.

[0016] The guide wheel moving assembly facilitates the overall movement along the track, and the unloading block facilitates the overall descent or lifting, which is beneficial for the demoulding of the beam bottom formwork, preventing the demoulding template from hitting the beam bottom during the overall movement, and is beneficial for controlling the overall structure below the beam bottom elevation. After moving to the next construction section, the unloading block is adjusted to move the beam bottom formwork back to the beam bottom elevation.

[0017] As a further improvement of the present invention, the U-shaped frame is located in the overhead layer, and includes vertical pipes on both sides and a horizontal pipe at the bottom. The upper ends of the vertical pipes are lower than the top surface of the truss beam to reserve storage space, and the vertical pipes are fixed to the side of the truss beam;

[0018] Multiple gantry support frames spaced apart from each other are connected as a whole through longitudinal beams on both sides of the top. The columns on both sides of the gantry support frame are slidably installed in the vertical tubes on both sides of the U-shaped frame, and the top crossbeam is located between the longitudinal beams on both sides.

[0019] The hydraulic jack is installed on the bottom cross tube, and its upper end piston head is fixed to the bottom surface of the top cross beam;

[0020] The inner sides of the vertical pipes on both sides of the U-shaped frame are fixed with longitudinal joists, and spaced support plates are installed on the joists; hydraulic jacks extend between the support plates;

[0021] The upright posts and upright pipes are provided with bolt holes at corresponding positions and are adapted with detachable limit bolts.

[0022] With this structure, after removing the limit of the portal support frame and the U-shaped frame, the column can move in the riser;

[0023] The pallet is used to place the plate bottom mold. After the hydraulic jack is retracted, the pallet can receive the plate bottom mold.

[0024] When the gantry support frame supports the bottom mold of the plate, the limit bolts can be used to penetrate the bolt holes to achieve the limit between the gantry support frame and the U-shaped frame; when demolding, the limit can be released, which is conducive to demolding with the hydraulic jack.

[0025] As a further improvement of the present invention, a circle of grooves is provided on the circumferential surface of the piston head, the cross-section of the groove is C-shaped, and a movable head is slidably assembled in the groove; the outer side of the movable head is fixedly connected to a cross bar, and the outer end of the cross bar is fixedly connected to a cross plate; the cross plate slides and extends between the two support plates; the two support plates are fixed to the bottom surface of the cross beam of the portal support frame, and an oblong hole is provided on the support plate, and sliding shafts are provided on both sides of the cross plate to extend into the oblong hole.

[0026] With this structure, the movable head rotates along the groove to adjust the support position to ensure it is parallel to the beam; the sliding shaft moves along the oblong hole to adjust the telescopic length to adapt to the length of the beam, preventing the force points from being single or too close, which may easily break the beam.

[0027] As a further improvement of the present invention, triangular stiffening plates are provided between the longitudinal beams and the columns, and between the transverse beams and the columns;

[0028] A horizontal tube is fixed to the side of the vertical tube so that the column can slide downward and extend out of the vertical tube;

[0029] A ladder frame is also installed on the upper end of the lattice column.

[0030] With this structure, the triangular stiffening plates can strengthen the nodes of the portal support frame;

[0031] The horizontal tube is fixed on the side of the vertical tube, which does not affect the vertical column passing through the vertical tube downward, which is conducive to increasing the telescopic distance;

[0032] The ladder frame is convenient for construction workers to use.

[0033] As a further improvement of the present invention, the removable formwork assembly further comprises: first ribs arranged in a grid-like manner on the back sides of the beam bottom formwork, the beam side formwork and the slab bottom formwork;

[0034] Beam bottom formwork corbels are installed at intervals on the side ribs of the beam bottom formwork and are padded under the bottom ribs of the beam side formwork;

[0035] The beam bottom mold corbel hinge joint is fixed to the outer end of the beam bottom mold corbel, and includes a first fixed joint located in the middle and first rotating joints located on both sides. The first fixed joint and the first rotating joint share a pin shaft, wherein the first fixed joint is fixed to the outer end of the beam bottom mold corbel;

[0036] The rib plate is fixed between the first rotating joint and the bottom rib of the beam side form.

[0037] With such a structure, the beam side formwork can be leveled by the beam bottom formwork corbel; the beam side formwork can also rotate with the beam bottom formwork corbel through the beam bottom formwork corbel hinge. When the slab bottom formwork is disassembled and placed in the overhead layer, the beam side formwork 142 can be superimposed on the slab bottom formwork.

[0038] As a further improvement of the present invention, an internal angle mold is installed on the upper side of the beam side mold, and the internal angle mold includes:

[0039] Beam side angle formwork;

[0040] The slab bottom angle formwork is perpendicular to the beam side angle formwork, and its side surface is flush with the inside of the top of the beam side angle formwork, thus forming a right angle with the beam side angle formwork;

[0041] A hinge groove is provided at the inner corner formed by the beam side angle formwork and the slab bottom angle formwork;

[0042] The internal angle mold hinge is embedded in the hinge groove and includes a second rotating section and a second fixed section which share a pin shaft. The second fixed section is fixed to the beam side angle template, and the second rotating section is fixed to the plate bottom angle template.

[0043] The second ribs are fixed to the beam side angle formwork and the plate bottom angle formwork, and the second ribs are arranged at the ends of the beam side angle formwork and the plate bottom angle formwork; a notch is formed at the intersection of the second ribs, and the notch is connected to the hinge groove to allow the internal angle formwork hinge to rotate;

[0044] A lug is provided at the end of the second rib, the lug is pin-connected to a support, a screw is installed on the support, and two screws are connected by a straight thread sleeve to form a diagonal brace;

[0045] The support has a U-shaped groove, and the U-shaped groove is adapted to the screw;

[0046] A full-length steel back rib is provided between the second ribs at both ends, and lugs for connecting the diagonal braces are arranged at intervals along the steel back rib;

[0047] A cross third rib is arranged between the steel back rib of the beam side angle formwork and the steel back rib of the plate bottom angle formwork, and a notch is also provided at the intersection of the third ribs.

[0048] The first ribs, the second ribs and the steel back ribs are provided with assembly holes.

[0049] With such a structure, the beam side angle formwork is installed on the upper side of the beam side formwork, and the slab bottom angle formwork is installed on both sides of the slab bottom formwork, thereby completing the installation of the internal angle formwork. When demolding, the limit of the slab bottom angle formwork and the slab bottom formwork is released, so that the slab bottom angle formwork and the slab bottom formwork can be separated, and the slab bottom formwork can be moved down to make space, and then the internal angle formwork is moved horizontally and then separated from the beam side formwork. After the concrete reaches the design strength, the beam bottom formwork is finally removed. The above scheme is conducive to asynchronous demolding and proper arrangement of demolding priority. When sliding formwork is used for construction, the internal angle formwork can also be moved longitudinally for removal, and the subsequent slab bottom formwork can also be raised and lowered, which is conducive to stacking the beam side formwork and the slab bottom formwork to store the formwork, and then sliding synchronously, which is conducive to saving space for storing the formwork and making full use of the overhead layer of the sliding system.

[0050] The second rib helps to strengthen the end of the internal angle mold; after the notch is opened, it prevents obstruction of rotation and is also conducive to loosening the internal angle mold; after the internal angle mold is disassembled, it can be rotated and retracted to lower the overall height, which is conducive to storage and passing below the bottom elevation of the beam.

[0051] The screw and straight thread sleeve facilitate the formation of diagonal bracing;

[0052] U-shaped groove is convenient for assembly and welding;

[0053] The steel back rib is helpful to reinforce the internal angle mold, and the lugs arranged on the steel back rib help to form diagonal braces on the steel back rib and strengthen the steel back rib.

[0054] The third rib helps to vertically support the steel back rib to prevent the steel back rib from bending along the formwork surface.

[0055] Bolt and nut fasteners are used to penetrate assembly holes to achieve the splicing of the internal angle formwork with the beam side formwork and the slab bottom formwork, and the internal angle formwork itself is extended by splicing.

[0056] As a further improvement of the present invention, the beam side formwork includes an upper side formwork and a lower side formwork and a beam side formwork hinge located therebetween, the beam side formwork hinge includes multiple hinge sections, the beam side formwork hinge includes a first hinge support fixed to the bottom surface of the first rib at the lower part of the upper side formwork and a second hinge support fixed to the top surface of the first rib at the upper part of the lower side formwork; at least two sections of concave hinge sections are arranged between the first hinge support and the second hinge support, the hinge section of the uppermost section is hinged to the first hinge support; the hinge section of the lowermost section is hinged to the second hinge support.

[0057] With this structure, the upper and lower molds are rotated and folded by the beam side mold hinge. After the beam side mold is removed, the upper mold is rotated and folded onto the lower mold with the inner sides of the molds touching each other. This further saves storage space and reduces the required storage width. At least two concave hinge sections are formed so that during the subsequent rotation, the concave multi-section hinge section can be expanded and extended, facilitating folding in the upper mold, avoiding the limitation of the hinge section length. The concave multi-section hinge section can store more length for extension.

[0058] As a further improvement of the present invention, the beam side form hinges are arranged in pairs as a group, and the first hinge support and the second hinge support are different in length. On the same first rib, the first hinge support of one beam side form hinge is arranged adjacent to the second hinge support of the other beam side form hinge, and the two sections form concave hinge sections that are staggered, with more than half of one concave section located in the upper side form; more than half of the other concave section is located in the lower side form, and a common pin shaft is provided in the two concave intersection sections.

[0059] With such a structure, the common pin shaft makes circular motion with the hinge point of the longer hinge support as the center, so that the concave multi-segment hinge section has a stable circular trajectory when it is unfolded. Due to the existence of the common pin shaft, the common pin shaft therein also makes circular motion while the multi-segment hinge section is unfolded, so that stable rotation occurs between the upper mold and the lower mold.

[0060] The hinge joint with the common pin is in a V-shape with an obtuse angle.

[0061] With this structure, after the multi-section hinge section is fully unfolded, the obtuse V-shaped hinge section can cross at an oblique angle when encountering the right angle of the upper or lower mold, thereby avoiding rigid collision.

[0062] As a further improvement of the present invention, a rotatable safety guardrail is also included, which includes:

[0063] Edge corbels, which are installed at intervals on the outside of the truss beams at the edge;

[0064] slab, which is laid on edge corbels;

[0065] a balustrade, the underside of which is hinged to the outer end of the edge corbel;

[0066] A railing hinge support, which is fixed to the outside of the railing upright;

[0067] A connecting rod, the upper end of which is hinged to the railing hinge support;

[0068] Hydraulic jacks for handrails, which are fixed transversely to the sides of the truss beams, below the edge corbels;

[0069] The piston end hinge support is fixed to the piston end of the hydraulic jack and hinged to the lower end of the connecting rod;

[0070] The railing and the edge corbel are hinged via a railing hinge section, wherein the railing hinge section comprises a railing rotation section and a corbel fixing section which share a common pin shaft, wherein the railing rotation section is fixed to the lower side of the railing, and the corbel fixing section is fixed to the outer end of the edge corbel;

[0071] The connecting rod includes a first body and a second body, a first spring is arranged between the first body and the second body, one end of the first spring is fixed to the first body, and the other end is fixed to the second body;

[0072] The first body and the second body are provided with clamping hoops; and limiting rods are slidably provided through corresponding positions of the two clamping hoops.

[0073] Limiting nuts are provided at both ends of the limiting rod, and a second spring is provided between the limiting nut and the clamp;

[0074] A jack bracket is installed below the railing hydraulic jack, a reaction frame is arranged on the jack bracket, and the reaction frame fixes the railing hydraulic jack.

[0075] With such a structure, the piston rod is retracted by the railing hydraulic jack, and the connecting rod is driven by the railing hydraulic jack to rotate downward, thereby driving the railing to rotate, so that the railing can be leveled.

[0076] The rail hinge energy saving allows rotation between the rail and the edge corbel.

[0077] The split connecting rod can prevent the railing hydraulic jack from applying excessive pulling force, which may easily damage the connecting rod. The first spring provides a buffering effect and also enables the connecting rod to have a telescopic function to adapt to changes in the connecting rod length during the rotation process.

[0078] The clamp can prevent the connecting rod from bending;

[0079] The second spring enables the limit rod to have a reset function;

[0080] Reaction frame to strengthen and fix the hydraulic jack;

[0081] The railings are leveled so that they can pass under the concrete beams during subsequent slipform operations.

[0082] As a further improvement of the present invention, the railing end side is hinged with an angle steel, which can be flipped between the railing and the edge corbel, with one limb facing the end face of the edge corbel, and a pad is provided between one limb of the angle steel and the end face of the edge corbel.

[0083] A triangular reinforcement plate is provided between the two limbs of the angle steel.

[0084] Adopting such a structure can prevent the spring from pushing back the railing, thereby ensuring that the railing is in a stable state.

[0085] Triangular reinforcement plates can strengthen angle steel.

[0086] The present invention is beneficial to improving the construction efficiency of concrete floor slabs. During slipform construction, after the formwork is removed, it can be stacked in the overhead layer and can be moved perpendicular to the concrete beam to the next construction section. Compared with the slipform construction scheme that can only move along the concrete beam, it has a higher utilization rate and more flexible usage scenarios, and is suitable for the construction of heavier cover slabs with larger specifications.

[0129] The U-shaped frame 3 is arranged between the truss beams 1, and its top surface is lower than the top surface of the truss beam 1 to reserve space for stacking templates;

[0130] A portal support frame 4, which is slidably mounted on the U-shaped frame 3;

[0131] A hydraulic jack 5 is mounted on the U-shaped frame 3 and fixes the top support portal frame 4 to drive the portal support frame 4 to slide up and down along the U-shaped frame 3;

[0138] With such a structure, the overhead layer 2 can be used to stack the slab bottom formwork and the beam side formwork; the hydraulic jack 5 can drive the gantry support frame 4 to move up and down, and the gantry support frame 4 is used to fix the slab bottom formwork; the slab bottom formwork is spliced through the internal angle formwork and the beam side formwork, and after the limit of the slab bottom formwork and the internal angle formwork is released, the slab bottom formwork can be demoulded first by the hydraulic jack 5; after the beam side formwork and the internal angle formwork are removed, they can be stacked on the slab bottom formwork; the beam bottom formwork is fixed on the truss beam 1; after the slab bottom formwork, the beam side formwork and the internal angle formwork are placed, the unloading block 10 is lowered so that the beam bottom formwork can be demoulded, so that the height of the formwork after the overall demoulding will still not be higher than the beam bottom elevation, and the overall formwork can be slid along the width direction of the beam and moved to the next construction section.

[0139] The guide wheel moving assembly 8 facilitates the movement of the whole along the track 9, and the unloading block 10 is conducive to the descent or lifting of the whole, which is conducive to the demoulding of the bottom form of the beam, preventing the demoulding template from hitting the bottom of the beam during the overall movement, and is conducive to controlling the whole below the bottom elevation of the beam. After moving to the next construction section, adjust the unloading block 10 to move the bottom form of the beam back to the bottom elevation of the beam.

[0140] In this embodiment, the U-shaped frame 3 is located in the overhead layer 2 and includes vertical pipes 301 on both sides and a horizontal pipe 302 at the bottom. The upper ends of the vertical pipes 301 are lower than the top surface of the truss beam 1 to reserve storage space. The vertical pipes 301 are fixed to the side of the truss beam 1.

[0141] A plurality of front-to-back spaced portal support frames 4 are connected as a whole by longitudinal beams 401 on both sides of the top. The columns 402 on both sides of the portal support frame 4 are slidably installed in the vertical pipes 301 on both sides of the U-shaped frame 3.

[0144] The upright column 402 and the upright pipe 301 are provided with bolt holes 6 at corresponding positions and are adapted with detachable limit bolts 7 .

[0145] With this structure, after the limit of the portal support frame 4 and the U-shaped frame 3 is released, the column 402 can move in the riser 301;

[0146] The support plate 304 is used to place the plate bottom mold. After the hydraulic jack 5 is retracted, the support plate 304 can bear the plate bottom mold;

[0147] When the gantry support frame 4 supports the plate bottom mold, the limit bolt 7 can be used to penetrate the bolt hole 6 to achieve the limit between the gantry support frame 4 and the U-shaped frame 3; when demolding, the limit can be released, which is conducive to demolding by the hydraulic jack 5.

[0148] In this embodiment, a circle of grooves 5011 are provided on the circumference of the piston head 501, and the cross-section of the grooves 5011 is C-shaped. A movable head 5012 is slidably assembled in the grooves 5011; the outer side of the movable head 5012 is fixedly connected to a cross bar 5013, and the outer end of the cross bar 5013 is fixedly connected to a cross plate 5014; the cross plate 5014 slides and extends between the two support plates 5015; the two support plates 5015 are fixed to the bottom surface of the cross beam 403 of the portal support frame 4, and an oblong hole 5016 is provided on the support plate 5015, and sliding shafts 5017 are provided on both sides of the cross plate 5014 to extend into the oblong hole 5016.

[0149] With such a structure, the movable head 5012 rotates along the groove 5011 to adjust the support position to ensure that it is parallel to the beam 403; the sliding shaft 5017 moves along the oblong hole 5016 to adjust the telescopic length to adapt to the length of the beam 403, preventing the force points from being single or too close, which may easily break the beam 403.

[0150] In this embodiment, triangular stiffening plates 404 are provided between the longitudinal beam 401 and the column 402 , and between the transverse beam 403 and the column 402 ;

[0151] A horizontal tube 302 is fixed to the side of the vertical tube 301 so that the column 402 can slide downward and extend out of the vertical tube 301;

[0152] A ladder frame 12 is also installed on the upper end of the lattice column 11.

[0153] With such a structure, the triangular stiffening plate 404 can strengthen the nodes of the portal support frame 4;

[0154] The horizontal tube 302 is fixed to the side of the vertical tube 301, which does not affect the vertical column 402 passing through the vertical tube 301 downward, which is conducive to increasing the telescopic distance;

[0155] The ladder frame 12 is convenient for construction workers to use.

[0156] In this embodiment, the removable formwork assembly 14 further includes: first ribs 145 , which are arranged in a grid-like manner on the back of the beam bottom formwork 141 , the beam side formwork 142 , and the plate bottom formwork 143 ;

[0157] Beam bottom formwork corbels 146 are installed at intervals on the side ribs of the beam bottom formwork 2 and are padded under the bottom ribs of the beam side formwork 142;

[0158] The beam bottom mold corbel hinge section 147 is fixed to the outer end of the beam bottom mold corbel 146, and includes a first fixed section 148 located in the middle and first rotating sections 149 located on both sides. The first fixed section 148 and the first rotating section 149 share a pin shaft, wherein the first fixed section 148 is fixed to the outer end of the beam bottom mold corbel 146;

[0159] The rib plate 1410 is fixed between the first rotating joint 149 and the bottom rib of the beam side form 142 .

[0160] With such a structure, the beam side formwork 142 can be leveled by the beam bottom formwork corbel 146; the beam side formwork 142 can also rotate with the beam bottom formwork corbel 146 through the beam bottom formwork corbel hinge 147. When the slab bottom formwork is disassembled and placed in the overhead layer, the beam side formwork 142 can be superimposed on the slab bottom formwork.

[0161] In this embodiment, an internal angle mold 144 is installed on the upper side of the beam side mold 142. The internal angle mold 144 includes:

[0162] Beam side angle formwork 1441;

[0163] The slab bottom angle formwork 1442 is perpendicular to the beam side angle formwork 1441, and its side surface is flush with the inner side of the top of the beam side angle formwork 1441, thereby forming a right angle with the beam side angle formwork 1441;

[0164] Hinge slot 1443, which is provided at the inner corner formed by beam side angle form 1441 and slab bottom angle form 1442;

[0165] The internal angle mold hinge 1444 is embedded in the hinge groove 1443 and includes a second rotating joint 1445 and a second fixed joint 1446 which share a common pin shaft. The second fixed joint 1446 is fixed to the beam side angle mold 1441, and the second rotating joint 1445 is fixed to the plate bottom angle mold 1442.

[0166] Second ribs 1447 are fixed to the beam side angle formwork 1441 and the slab bottom angle formwork 1442. The second ribs 1447 are arranged at the ends of the beam side angle formwork 1441 and the slab bottom angle formwork 1442. Notches 1448 are formed at the intersections of the second ribs 1447. The notches 1448 are connected to the hinge grooves 1443 to allow the internal angle form hinges 1444 to rotate.

[0167] A lug 1449 is provided at the end of the second rib 1447, and the lug 1449 is pin-connected to a support 14410, a screw 14411 is installed on the support 14410, and two screws 14411 are connected by a straight thread sleeve 14412 to form a diagonal brace;

[0168] The support 14410 has a U-shaped groove 144101, and the U-shaped groove 144101 is adapted to the screw 14411;

[0169] A continuous steel back rib 14413 is provided between the second ribs 1447 at both ends, and lugs 1449 for connecting to the diagonal braces are arranged at intervals along the steel back rib 14413;

[0170] A cross third rib 14414 is provided between the steel back rib 14413 of the beam side angle formwork 1441 and the steel back rib 14413 of the plate bottom angle formwork 1442 , and a notch 1448 is also provided at the intersection of the third ribs 14414 .

[0171] Assembly holes 1411 are formed on the first rib 145 , the second rib 1447 and the steel back rib 14413 .

[0172] With such a structure, the beam side angle formwork 1441 is installed on the upper side of the beam side formwork 142, and the slab bottom angle formwork 1442 is installed on both sides of the slab bottom formwork 143, thereby completing the installation of the internal angle formwork 144. When demolding, the limit of the slab bottom angle formwork 1442 and the slab bottom formwork 143 is released, so that the slab bottom angle formwork 1442 and the slab bottom formwork 143 can be separated, and the slab bottom formwork 143 can be moved down to make space, and then the internal angle formwork 144 is moved horizontally, and then separated from the beam side formwork 142. After the concrete reaches the design strength, the beam bottom formwork 141 is finally removed. The above scheme helps to demold asynchronously and properly arrange the demolding priority. When sliding formwork is used for construction, the internal angle formwork 144 can also be moved longitudinally for removal, and the subsequent slab bottom formwork 143 can also be raised and lowered, which helps to stack the beam side formwork 142 and the slab bottom formwork 143 to store the formwork, and then slide synchronously, which is beneficial to save space for storing the formwork and make full use of the overhead layer of the sliding system.

[0173] The second rib 1447 helps to strengthen the end of the internal angle mold 144; after the notch 1448 is opened, it prevents obstruction of rotation and is also conducive to loosening the internal angle mold 144; after the internal angle mold 144 is disassembled, it can be rotated and retracted to lower the overall height, which is conducive to storage and passing below the bottom elevation of the beam.

[0174] The screw 14411 and the straight threaded sleeve 14412 facilitate forming a diagonal brace;

[0175] U-shaped groove 144101 facilitates assembly and welding;

[0176] The steel back rib 14413 is helpful to reinforce the internal angle mold 144, and the lug 1449 is arranged on the steel back rib 14413, which helps to form a diagonal brace on the steel back rib 14413 and strengthen the steel back rib.

[0177] The third rib 14414 is helpful to vertically support the steel back rib 14 to prevent the steel back rib 14 from bending along the template surface.

[0178] Bolt and nut fasteners are used to penetrate the assembly holes 1411 to achieve the splicing of the internal angle mold 144 with the beam side mold 142 and the plate bottom mold 143, and the internal angle mold itself is extended by splicing.

[0179] In this embodiment, the beam side mold 142 includes an upper side mold 1421 and a lower side mold 1422 and a beam side mold hinge 1423 located therebetween. The beam side mold hinge 1423 includes multiple hinge sections 14231. The beam side mold hinge 1423 includes a first hinge support 14232 fixed to the bottom surface of the first rib 145 at the lower part of the upper side mold 1421 and a second hinge support 14233 fixed to the top surface of the first rib 145 at the upper part of the lower side mold 1422. At least two concave hinge sections 14231 are arranged between the first hinge support 14232 and the second hinge support 14233. The uppermost hinge section 14231 is hinged to the first hinge support 14232. The lowermost hinge section 14231 is hinged to the second hinge support 14233.

[0180] With this structure, the upper mold 1421 and the lower mold 1422 are rotated and folded through the beam mold hinge 1423. After the beam mold 142 is disassembled, the upper mold 1421 is rotated and folded onto the lower mold 1422 with the inner sides of the molds touching each other. This further saves storage space and reduces the required storage width. At least two concave hinge sections 14231 are formed to facilitate the expansion and extension of the concave multi-section hinge section during the subsequent rotation process, facilitating the folding of the upper mold 1421, thereby avoiding the limitation of the hinge section length. The concave multi-section hinge section can store more length for extension.

[0181] In this embodiment, the beam side mold hinges 1423 are arranged in pairs as a group, and the first hinge support 14232 and the second hinge support 14233 are of different lengths. On the same first rib 145, the first hinge support 14232 of one beam side mold hinge 1423 is arranged adjacent to the second hinge support 14233 of the other beam side mold hinge 1423, and the two sections form concave hinge sections 14231 that are staggered. One concave section has more than half of its portion located in the upper side mold 1421; the other concave section has more than half of its portion located in the lower side mold 1422, and a common pin shaft 14234 is provided at the two concave intersections to pass through.

[0182] By adopting such a structure, the common pin shaft 14234 makes a circular motion with the hinge point of the longer hinge support as the center of the circle, so that the concave multi-segment hinge section 14231 has a stable circular trajectory when it is unfolded. Due to the existence of the common pin shaft 14234, when the multi-segment hinge section 14231 is unfolded, the common pin shaft 14234 therein also makes a circular motion at the same time, so that a stable rotation occurs between the upper mold 1421 and the lower mold 1422.

[0183] The hinge joint 1031 of the common pin 106 is in an obtuse V-shape.

[0184] With this structure, after the multi-section hinge section 14231 is fully unfolded, the obtuse V-shaped hinge section 14231 can cross over at an oblique angle when encountering the right angle of the upper mold 1421 or the lower mold 1422, thereby avoiding rigid collision.

[0185] In this embodiment, a rotatable safety guardrail 15 is also included, which includes:

[0186] Edge corbels 151, which are installed at intervals on the outside of the truss beam 1 at the edge position;

[0187] a flat plate 152 , which is laid on the edge corbel 151 ;

[0188] A railing 153, the lower side of which is hinged to the outer end of the edge corbel 151;

[0189] A railing hinge support 154, which is fixed to the outside of the upright of the railing 153;

[0190] A connecting rod 155, the upper end of which is hinged to the railing hinge support 154;

[0191] A handrail hydraulic jack 156, which is laterally fixed to the side of the truss beam 1, below the edge corbel 151;

[0192] The piston end hinge support 157 is fixed to the piston end of the hydraulic jack and hinged to the lower end of the connecting rod 155;

[0193] The railing 153 and the edge corbel 151 are hinged via a railing hinge 158. The railing hinge 158 includes a railing rotation joint 1581 and a corbel fixing joint 1582 that share a common pin. The railing rotation joint 1581 is fixed to the lower side of the railing 153, and the corbel fixing joint 1582 is fixed to the outer end of the edge corbel 151.

[0194] The connecting rod 155 includes a first body 1551 and a second body 1552. A first spring 1553 is disposed between the first body 1551 and the second body 1552. One end of the first spring 1553 is fixed to the first body 1551, and the other end is fixed to the second body 1552.

[0195] The first body 1551 and the second body 1552 are provided with clamps 1554 ; and limiting rods 1555 are slidably provided through corresponding positions of the two clamps 1554 .

[0196] Limiting nuts 1556 are provided at both ends of the limiting rod 1555, and a second spring 1557 is provided between the limiting nuts 1556 and the clamp 1554;

[0197] A jack bracket 159 is installed below the railing hydraulic jack 156 , and a reaction frame 1510 is provided on the jack bracket 159 . The reaction frame 1510 fixes the railing hydraulic jack 156 .

[0198] With such a structure, the piston rod is retracted by the railing hydraulic jack 156 , and the connecting rod 155 is driven by the railing hydraulic jack 156 to rotate downward, thereby driving the railing 153 to rotate, so that the railing 153 can be leveled.

[0199] The rail hinge 158 allows rotation between the rail 153 and the edge corbel 151 .

[0200] The split connecting rod can prevent the railing hydraulic jack 156 from applying excessive pulling force, which may easily damage the connecting rod 155. The first spring 1553 provides a buffering effect and also enables the connecting rod 155 to have a telescopic function to adapt to the change in the length of the connecting rod 155 during the rotation process.

[0201] The clamp 1554 can prevent the connecting rod 155 from bending;

[0202] The second spring 1557 enables the limiting rod 1555 to have a reset function;

[0203] Reaction frame 1510 is used to strengthen and fix the hydraulic jack 7;

[0204] The railings are leveled so that they can pass under the concrete beams during subsequent slipform operations.

[0205] In this embodiment, the end side of the railing 153 is hinged to the angle steel 1511, and the angle steel 1511 can be flipped between the railing 153 and the edge corbel 151, and one of its limbs is opposite to the end face of the edge corbel 151, and a pad 1512 is set between one limb of the angle steel 1511 and the end face of the edge corbel 151.

[0206] A triangular reinforcement plate 1513 is provided between the two limbs of the angle steel 1511 .

[0207] With such a structure, the spring can be prevented from pushing back the handrail 153, thereby ensuring that the handrail 153 is in a stable state.

[0208] The triangular reinforcement plate 1513 can reinforce the angle steel 10 .

[0209] Example 2

[0210] like Figures 1-19 As shown, a construction method of a heavy cover plate construction machine specifically includes the following steps:

[0211] S1: Install the construction machine, install the pre-buried corbels 13 of the structural columns along the cast structural columns, and install the lattice columns 11 at intervals between the structural columns;

[0215] S5: Install the truss beam 1 on the guide wheel moving assembly 8. The truss beam 1 is installed at intervals, and an overhead layer 2 is formed at the intervals;

[0216] S6: Install the U-shaped frame 3 between the truss beams 1. The top surface of the U-shaped frame 3 should be installed lower than the top surface of the truss beam 1 to reserve space for stacking the templates.

[0217] S7: Install a hydraulic jack 5 and a slidable portal support frame 4 on the U-shaped frame 3, and the portal support frame 4 is fixed and supported by the hydraulic jack 5;

[0218] S8: Install the removable formwork assembly 14 and lay the beam bottom formwork 141 on the truss beam 1; install the beam side formwork 142 on the side of the beam bottom formwork 141, and install the internal angle formwork 144 on the upper end of the beam side formwork 142; lay the plate bottom formwork 141 on the portal support frame 4, and fix the plate bottom formwork 141 and the internal angle formwork 144 in position;

[0219] S9: Pour beam and slab concrete.

[0220] In this embodiment, it also includes:

[0221] S10: When removing the mold, first release the fixed limit of the bottom mold 141 and the internal angle mold 144;

[0222] S11: Start the hydraulic jack 5 to dismantle the plate bottom mold 141, and lower the plate bottom mold 141 to the lower limit position, converting it into a U-shaped frame 3 to support the portal support frame 4;

[0223] S12: Release the fixed limits of the internal angle mold 144 and the beam side mold 142. First, remove the internal angle mold 144 and stack it on the plate bottom mold 141. Then, remove the beam side mold 142 and stack it on the plate bottom mold 141.

[0226] S15: Adjust the unloading block 10 to restore the plate bottom formwork 141 to the beam bottom elevation position, and then proceed with the construction of this construction section.

[0227] like Figure 19 As shown, legs can be set on the embedded corbels 13 of the two structural columns to build double I-beams, and then the unloading blocks 10 are installed on the double I-beams. The unloading blocks use tension screws to connect wedge blocks, and by loosening and tightening the nuts, multiple unloading blocks can be adjusted to a uniform elevation.

[0228] The present invention is beneficial to improving the construction efficiency of concrete floor slabs. During slipform construction, after the formwork is removed, it can be stacked in the overhead layer and can be moved perpendicular to the concrete beam to the next construction section. Compared with the slipform construction scheme that can only move along the concrete beam, it has a higher utilization rate and more flexible usage scenarios, and is suitable for the construction of heavier cover slabs with larger specifications.

[0229] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. Those skilled in the art will recognize that several equivalent substitutions or obvious modifications can be made without departing from the scope of the present invention, and that any equivalent performance or application should be considered to fall within the scope of protection of the present invention.
