Description

Technical Field

[0001] The present invention relates to the field of concrete floor slab construction, and particularly to a heavy cover plate construction machine. Background Art

[0002] For example, Chinese Patent Application Publication No. CN 106032705 A discloses an integral casting and forming construction method for a reinforced concrete floor slab. This integral casting and forming construction method for the reinforced concrete floor slab separately assembles a self-balanced overall structure forming a reinforced concrete beam and a reinforced concrete floor slab, hoists the separately assembled self-balanced structure, and pours concrete in the self-balanced formwork structure of the assembled floor slab to form an integrally cast reinforced concrete floor slab structure; its formwork support method generally relies on scaffolding for support; when the concrete floor slab has a larger specification, more scaffolding materials are consumed and the construction period is longer, which is not conducive to improving efficiency. Summary of the Invention

[0003] The object of the present invention is to provide a heavy cover plate construction machine, which is beneficial to improving the construction efficiency of concrete floor slabs. During slip form construction, after the formwork is removed, it can be stacked in the overhead floor and can move perpendicular to the concrete beam to the next construction section. Compared with the slip form construction scheme that can only move along the concrete beam, its utilization rate is higher and the usage scenario is more flexible, and it is applicable to the construction of heavier cover plates with larger specifications.

[0004] To achieve the above object, a heavy cover plate construction machine is adopted, which includes: Truss beams, which are arranged at intervals, and an overhead floor is formed between adjacent truss beams; U-shaped frames, which are arranged between the truss beams, and the top surface of the U-shaped frames is lower than the top surface of the truss beams to reserve a space for stacking formwork; Gantry support frames, which are slidably installed on the U-shaped frames; Hydraulic jacks, which are installed on the U-shaped frames and fixedly support the gantry support frames to drive the gantry support frames to slide up and down along the U-shaped frames; Guide wheel moving assemblies, which are installed at the bottoms of both ends of the truss beams; the guide wheel moving assemblies can be assembled with a reduction motor to drive the travel, or a horizontal jack can be installed on the track to push the truss beam as a whole, so as to achieve a sliding effect.

[0005] Tracks, which are laid under the guide wheel moving assemblies; Drop blocks, which are installed on the bottom surfaces of the tracks; Lattice columns, which support the bottom surfaces of the drop blocks under one end of the truss beams; Structural column embedded corbels, which are installed on the sides of the structural columns and support the bottom surfaces of the drop blocks under the other end of the truss beams; A demountable formwork assembly, which includes a bottom formwork of a beam installed on a truss beam, a side formwork of the beam installed on the side of the bottom formwork of the beam, a bottom formwork of a slab installed on a portal support frame, and an internal corner formwork detachably connected between the side formwork of the beam and the bottom formwork of the slab.

[0006] With such a structure, the bottom formwork of the slab and the side formwork of the beam can be stacked in the overhead floor; the hydraulic jack can drive the portal support frame to move up and down, and the portal support frame is used to fix the bottom formwork of the slab; the bottom formwork of the slab is spliced with the side formwork of the beam and the internal corner formwork. After the limit between the bottom formwork of the slab and the internal corner formwork is released, the bottom formwork of the slab can be demoulded first by the hydraulic jack; after the side formwork of the beam and the internal corner formwork are removed, they can be stacked on the bottom formwork of the slab; the bottom formwork of the beam is fixed on the truss beam; after the bottom formwork of the slab, the side formwork of the beam and the internal corner formwork are placed, the drop block is lowered, so that the bottom formwork of the beam can be demoulded, and the height of the formwork after overall demoulding is still not higher than the bottom elevation of the beam, so that it can be slid integrally along the width direction of the beam and moved to the next construction section.

[0007] The guide wheel moving assembly facilitates the overall movement along the track. The drop block is beneficial to the overall lowering or lifting, which is beneficial to the demoulding of the bottom formwork of the beam, prevents the demoulded formwork from touching the bottom of the beam during the overall movement, is beneficial to controlling the overall height below the bottom elevation of the beam. After moving to the next construction section, the drop block is adjusted so that the bottom formwork of the beam is moved back to the bottom elevation of the beam.

[0008] As a further improvement of the present invention, the U-shaped frame is located in the overhead floor, which includes two side vertical pipes and a bottom horizontal pipe. The upper ends of the vertical pipes are lower than the top surface of the truss beam to reserve a storage space, and the vertical pipes are fixed on the side of the truss beam; A plurality of portal support frames spaced front and back are connected as a whole through longitudinal beams on both sides of the top. The two side columns of the portal support frame are slidably installed in the two side vertical pipes of the U-shaped frame, and the top cross beam is between the two longitudinal beams; The hydraulic jack is installed on the bottom horizontal pipe, and its upper piston head is fixed on the bottom surface of the top cross beam; Longitudinal supporting beams are fixed on the inner sides of the two side vertical pipes of the U-shaped frame, and spaced supporting plates are installed on the supporting beams; the hydraulic jack extends between the supporting plates; Bolt holes are drilled through the columns and the vertical pipes at corresponding positions, and detachable limit bolts are adapted;

[0009] With such a structure, after the limit between the portal support frame and the U-shaped frame is released, the columns can move in the vertical pipes; The supporting plates are used to place the bottom formwork of the slab. After the hydraulic jack retracts, the bottom formwork of the slab can be received on the supporting plates; When the portal support frame supports the bottom formwork of the slab, the limit bolt can be inserted through the bolt hole to realize the limit between the portal support frame and the U-shaped frame; when demoulding, the limit can be released, which is beneficial to the demoulding by the hydraulic jack.

[0010] As a further improvement of the present invention, a groove is formed in 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; a cross bar is fixedly connected to the outer side of the movable head, and a cross plate is fixedly connected to the outer end of the cross bar; the cross plate slides into the space between two support plates; the two support plates are fixed to the bottom surface of the cross beam of the gantry support frame, long circular holes are formed in the support plates, and sliding shafts are arranged on both sides of the cross plate and extend into the long circular holes.

[0011] With such a structure, the movable head can rotate along the groove to adjust the support orientation to ensure parallelism with the cross beam; the sliding shaft can move along the long circular hole to adjust the telescopic length to adapt to the length of the cross beam, preventing a single or too close stress point and easily breaking the cross beam.

[0012] As a further improvement of the present invention, triangular stiffening plates are provided between the longitudinal beam and the column, and between the cross beam and the column; A horizontal pipe is fixed to the side surface of the riser pipe so that the column can slide downward and extend out of the riser pipe; A ladder is further installed at the upper end of the lattice column.

[0013] With such a structure, the triangular stiffening plates can strengthen the joints of the gantry support frame; The horizontal pipe is fixed to the side surface of the riser pipe, which does not affect the column passing through the riser pipe downward and is beneficial to increasing the telescopic distance; The ladder is beneficial for construction workers to use.

[0014] As a further improvement of the present invention, the detachable formwork assembly further includes: first ribs, which are arranged in a grid form on the back surfaces of the beam bottom formwork, beam side formwork and slab bottom formwork; Beam bottom formwork brackets, which 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; Beam bottom formwork bracket hinge joints, which are fixed to the outer ends of the beam bottom formwork brackets and include a first fixed joint located in the middle position and first rotating joints located on both sides. The first fixed joint and the first rotating joints share a pin shaft. Among them, the first fixed joint is fixed to the outer end of the beam bottom formwork bracket; Rib plates, which are fixed between the first rotating joints and the bottom ribs of the beam side formwork.

[0015] With such a structure, the beam side formwork can be leveled by the beam bottom formwork brackets; the beam side formwork can also rotate with the beam bottom formwork brackets through the beam bottom formwork bracket hinge joints. When the slab bottom formwork is disassembled and placed in the overhead floor, the beam side formwork 142 can be stacked on the slab bottom formwork.

[0016] As a further improvement of the present invention, a corner formwork is installed on the upper side of the beam side formwork. The corner formwork includes: Beam side angle formwork; Slab bottom angle formwork, which is perpendicular to the beam side angle formwork, and the side surface of which is flush with the inner side of the top of the beam side angle formwork, thus forming a right angle with the beam side angle formwork; A hinge groove is formed at the internal corner formed by the side formwork of the beam and the bottom formwork of the slab. An internal corner form hinge is embedded in the hinge groove. It includes a second rotating joint and a second fixed joint sharing a common pin shaft. The second fixed joint is fixedly connected to the side formwork of the beam, and the second rotating joint is fixedly connected to the bottom formwork of the slab.

[0017] Second ribs are fixedly connected to the side formwork of the beam and the bottom formwork of the slab. The second ribs are arranged at the ends of the side formwork of the beam and the bottom formwork of the slab. A notch is formed at the intersection of the second ribs, and the notch communicates with the hinge groove to allow the internal corner form hinge to rotate. Lugs are provided at the ends of the second ribs. The lugs are pin-connected to supports, and screws are installed on the supports. Two screws are connected by a straight thread sleeve to form a diagonal brace. The support has a U-shaped groove, and the U-shaped groove is adapted to the screw. 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. Crossed third ribs are provided between the steel back rib of the side formwork of the beam and the steel back rib of the bottom formwork of the slab, and notches are also formed at the intersections of the third ribs.

[0018] Assembly holes are formed on the first ribs, second ribs and steel back ribs.

[0019] With such a structure, the side formwork of the beam is installed on the upper side of the side form of the beam, and the bottom formwork of the slab is installed on both sides of the bottom form of the slab, thus completing the installation of the internal corner form. During demoulding, the limit between the bottom formwork of the slab and the bottom form of the slab is released, so that the bottom formwork of the slab and the bottom form of the slab can be separated. The bottom form of the slab can then move downwards to create space, and then the internal corner form is moved horizontally and then separated from the side form of the beam. When the concrete reaches the designed strength, finally the bottom form of the beam is removed. The above solution helps with asynchronous demoulding and properly arranges the demoulding priority. When slip form construction is adopted, the internal corner form can also be longitudinally removed, and subsequently the bottom form of the slab can also be lifted and lowered, which helps with stacking and storing the side form of the beam and the bottom form of the slab, and then synchronously sliding, which is beneficial to saving the space for storing the formwork and making full use of the overhead layer of the sliding system.

[0020] The second ribs help to strengthen the ends of the internal corner form. After the notch is formed, it prevents hindering rotation and is also beneficial to loosening the internal corner form. After the internal corner form is disassembled, it can rotate and contract, reducing the overall height, which is beneficial to storage and passing below the elevation of the bottom of the beam.

[0021] The screw and the straight thread sleeve facilitate the formation of a diagonal brace. The U-shaped groove is beneficial to assembly and welding. The steel back rib is beneficial to strengthening the internal corner form. The lugs are arranged on the steel back rib, which helps to form a diagonal brace on the steel back rib and strengthen the steel back rib.

[0022] The third rib is beneficial to vertically support the steel back rib to prevent the steel back rib from bending along the surface of the formwork.

[0023] Bolts and nuts fasteners are passed through the assembly holes to realize the splicing of the internal corner formwork with the side formwork of the beam and the bottom formwork of the slab, and its own extension by splicing.

[0024] As a further improvement of the present invention, the side formwork of the beam includes an upper side formwork, 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 concave hinge sections are arranged between the first hinge support and the second hinge support. The uppermost hinge section is hinged to the first hinge support; the lowermost hinge section is hinged to the second hinge support.

[0025] With such a structure, the upper side formwork and the lower side formwork are rotated and folded through the beam side formwork hinge. After the beam side formwork is removed from the formwork, the upper side formwork rotates and folds onto the lower side formwork in the form of the inner sides of the formworks being attached to each other; further saving storage space and reducing the required width for storage; at least two concave hinge sections facilitate the formation of a concave multi-section hinge that can expand and elongate during subsequent rotation, facilitating the inner folding of the upper side formwork and avoiding being restricted by the length of the hinge section; the concave multi-section hinge can store more length available for elongation; As a further improvement of the present invention, the beam side formwork hinges are arranged in pairs. The first hinge support and the second hinge support have different lengths. On the same first rib, the first hinge support of one beam side formwork hinge is arranged adjacent to the second hinge support of another beam side formwork hinge. The two concave hinge sections are arranged in a staggered manner. More than half of one concave part is located in the upper side formwork; more than half of the other concave part is located in the lower side formwork. A common pin shaft is arranged through the cross part of the two concave parts.

[0026] With such a structure, the common pin shaft makes a circular motion around the hinge point of the longer hinge support, so that the expansion of the concave multi-section hinge has a stable circular trajectory. Due to the existence of the common pin shaft, while the multi-section hinge expands, the common pin shaft also makes a circular motion at the same time, enabling a stable rotation between the upper side formwork and the lower side formwork.

[0027] The hinge section of the common pin shaft is in an obtuse V shape.

[0028] With such a structure, after the multi-section hinge is fully expanded, when the hinge section in an obtuse V shape encounters a right angle of the upper side formwork or the lower side formwork, it can cross obliquely to avoid rigid collision.

[0029] As a further improvement of the present invention, it further includes a rotatable safety railing, which includes: Edge brackets, which are installed at intervals on the outer side of the truss beam at the edge position; A flat plate, which is laid on the edge corbel; A railing, the lower side of which is hinged to the outer end of the edge corbel; A railing hinge support, which is fixed to the outside of the vertical pole of the railing; A connecting rod, the upper end of which is hinged to the railing hinge support; A railing hydraulic jack, which is horizontally fixed to the side of the truss beam and is located below the edge corbel; A piston end hinge support, which is fixed to the piston end of the hydraulic jack and is hinged to the lower end of the connecting rod; The railing and the edge corbel are hinged through a railing hinge joint, and the railing hinge joint includes a railing rotating joint and a corbel fixing joint sharing a pin shaft. The railing rotating joint is fixed to the lower side of the railing, and the corbel fixing joint is fixed to the outer end of the edge corbel; The connecting rod includes a first body and a second body, and 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; Hooping is arranged on the first body and the second body; a limiting rod is slidably penetrated through corresponding positions of the two hoopings.

[0030] Limiting nuts are arranged at both ends of the limiting rod, and a second spring is arranged between the limiting nuts and the hooping; A jack corbel is installed under the railing hydraulic jack, and a reaction frame is arranged on the jack corbel, and the reaction frame fixes the railing hydraulic jack.

[0031] With such a structure, by retracting the piston rod of the railing hydraulic jack, 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 laid flat.

[0032] The railing hinge joint allows rotation between the railing and the edge corbel.

[0033] The split connecting rod can prevent the excessive pulling force of the railing hydraulic jack from easily damaging the connecting rod. The first spring provides a buffering effect and also enables the connecting rod to have a telescopic function to adapt to the change in the length of the connecting rod during the rotation process.

[0034] The hooping can prevent the connecting rod from bending; The second spring enables the limiting rod to have a reset function; The reaction frame strengthens the fixation of the hydraulic jack; After the railing is laid flat, when the subsequent slip form operation is carried out, the railing can pass through from below the concrete beam.

[0035] As a further improvement of the present invention, an angle steel is hinged to the end side of the railing. The angle steel can be flipped between the railing and the edge corbel, and one of its limbs is opposite to the end face of the edge corbel, and a cushion block is arranged between one limb of the angle steel and the end face of the edge corbel.

[0036] A triangular reinforcing plate is arranged between the two legs of the angle steel.

[0037] Adopting such a structure can prevent the spring from pushing the railing backward, thereby ensuring the railing is in a stable state.

[0038] The triangular reinforcing plate can strengthen the angle steel.

[0039] The present invention is beneficial to improving the construction efficiency of concrete floor slabs. During slip form construction, after the formwork is removed, it can be stacked in the overhead floor and can move perpendicular to the concrete beam to the next construction section. Compared with the slip form construction plan that can only move along the concrete beam, its utilization rate is higher, the usage scenario is more flexible, and it is applicable to the construction of heavier floor slabs with larger specifications.

[0068] With such a structure, the movable head 5012 rotates along the groove 5011, and the support orientation can be adjusted to ensure parallelism with the cross beam 403; The sliding shaft 5017 moves along the long circular hole 5016, and the telescopic length can be adjusted to adapt to the length of the cross beam 403, preventing the stress points from being single or too close, which is likely to break the cross beam 403.

[0069] In this embodiment, triangular stiffening plates 404 are arranged between the longitudinal beam 401 and the column 402, and between the cross beam 403 and the column 402; A cross pipe 302 is fixed to the side surface of the vertical pipe 301 so that the column 402 can slide downward and extend out of the vertical pipe 301; A ladder rack 12 is further installed at the upper end of the lattice column 11.

[0070] With such a structure, the triangular stiffening plate 404 can strengthen the joints of the gantry support frame 4; The horizontal pipe 302 is fixed to the side of the vertical pipe 301, without affecting the downward penetration of the column 402 through the vertical pipe 301, which is beneficial to increasing the telescopic distance; The ladder frame 12 is beneficial for construction workers to use.

[0071] In this embodiment, the detachable formwork assembly 14 further includes: first ribs 145, which are arranged in a grid form on the back of the beam bottom form 141, the beam side form 142 and the slab bottom form 143; Beam bottom form corbels 146, which are installed at intervals on the side ribs of the beam bottom form 2 and are padded under the bottom ribs of the beam side form 142; Beam bottom form corbel hinge joints 147, which are fixed to the outer ends of the beam bottom form corbels 146, and include a first fixed joint 148 at the middle position and first rotating joints 149 at both side positions. The first fixed joint 148 and the first rotating joints 149 share a pin shaft. Among them, the first fixed joint 148 is fixed to the outer end of the beam bottom form corbel 146; Rib plates 1410, which are fixed between the first rotating joints 149 and the bottom ribs of the beam side form 142.

[0072] With such a structure, the beam side form 142 can be leveled by the beam bottom form corbels 146; the beam side form 142 can also rotate with the beam bottom form corbels 146 through the beam bottom form corbel hinge joints 147. When the slab bottom form is disassembled and placed in the overhead floor, the beam side form 142 can be stacked on the slab bottom form.

[0073] In this embodiment, a female corner form 144 is installed on the upper side of the beam side form 142, and the female corner form 144 includes: Beam side angle form 1441; Slab bottom angle form 1442, which is perpendicular to the beam side angle form 1441, and its side is flush with the inner side of the top of the beam side angle form 1441, so as to form a right angle with the beam side angle form 1441; Hinge grooves 1443, which are opened at the female corner formed by the beam side angle form 1441 and the slab bottom angle form 1442; Female corner form hinges 1444, which are embedded in the hinge grooves 1443, and include a second rotating joint 1445 and a second fixed joint 1446 that share a pin shaft. The second fixed joint 1446 is fixedly connected to the beam side angle form 1441, and the second rotating joint 1445 is fixedly connected to the slab bottom angle form 1442.

[0074] A second rib 1447 is fixedly connected to the side angle formwork 1441 of the beam and the bottom angle formwork 1442 of the slab. The second rib 1447 is arranged at the end of the side angle formwork 1441 of the beam and the bottom angle formwork 1442 of the slab; a notch 1448 is formed at the intersection of the second ribs 1447, and the notch 1448 communicates with the hinge groove 1443 for the rotation of the internal corner formwork hinge 1444; Lugs 1449 are arranged at the ends of the second ribs 1447. The lugs 1449 are pin-connected to supports 14410, and screws 14411 are installed on the supports 14410. The two screws 14411 are connected by a straight thread sleeve 14412 to form a diagonal brace; The support 14410 has a U-shaped groove 144101, and the U-shaped groove 144101 is adapted to the screw 14411; A full-length steel back rib 14413 is arranged between the second ribs 1447 at both ends, and lugs 1449 for connecting the diagonal braces are arranged at intervals along the steel back rib 14413; Crossed third ribs 14414 are arranged between the steel back rib 14413 of the side angle formwork 1441 of the beam and the steel back rib 14413 of the bottom angle formwork 1442 of the slab, and notches 1448 are also formed at the intersections of the third ribs 14414.

[0075] Assembly holes 1411 are formed in the first ribs 145, the second ribs 1447 and the steel back ribs 14413.

[0076] With such a structure, the side angle formwork 1441 of the beam is installed on the upper side of the side formwork 142 of the beam, and the bottom angle formwork 1442 of the slab is installed on both sides of the bottom formwork 143 of the slab, thus completing the installation of the internal corner formwork 144. During demoulding, the limit between the bottom angle formwork 1442 of the slab and the bottom formwork 143 of the slab is released, so that the bottom angle formwork 1442 of the slab and the bottom formwork 143 of the slab can be separated. The bottom formwork 143 of the slab can then move downwards to create space, and then the internal corner formwork 144 is moved horizontally and then separated from the side formwork 142 of the beam. After the concrete reaches the designed strength, finally the bottom formwork 141 of the beam is removed. The above scheme helps to demould out of sync and properly arrange the demoulding priority. When slip form construction is adopted, the internal corner formwork 144 can also be longitudinally removed, and subsequently the bottom formwork 143 of the slab can also be lifted and lowered, which helps the side formwork 142 of the beam and the bottom formwork 143 of the slab to be stacked and stored, and then synchronously slid, which is beneficial to saving the space for storing formwork and making full use of the overhead layer of the slip system.

[0077] The second rib 1447 helps to strengthen the end of the internal corner formwork 144; after the notch 1448 is formed, it prevents obstruction of rotation and is also beneficial to loosening the internal corner formwork 144; after the internal corner formwork 144 is disassembled, it can be rotated and contracted, reducing the overall height, which is beneficial to storage and passing below the beam bottom elevation.

[0078] The screw 14411 and the straight thread sleeve 14412 facilitate the formation of a diagonal brace; The U-shaped groove 144101 is conducive to assembly and convenient for welding; The steel back rib 14413 is beneficial to reinforce the internal corner formwork 144. 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.

[0079] The third rib 14414 is beneficial to vertically support the steel back rib 14 to prevent the steel back rib 14 from bending along the surface of the formwork.

[0080] The bolt and nut fasteners are passed through the assembly holes 1411 to realize the splicing of the internal corner formwork 144 with the side formwork 142 of the beam and the bottom formwork 143 of the slab, and its own extension by the splicing method.

[0081] In this embodiment, the side formwork 142 of the beam includes an upper side formwork 1421, a lower side formwork 1422 and a side formwork hinge 1423 located between the two. The side formwork hinge 1423 includes multiple hinge sections 14231. The side formwork 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 formwork 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 formwork 1422; at least two concave-shaped 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.

[0082] With such a structure, the upper side formwork 1421 and the lower side formwork 1422 are rotated and folded through the side formwork hinge 1423. After the side formwork 142 is removed from the formwork, the upper side formwork 1421 rotates and folds onto the lower side formwork 1422 in the form of the inner sides of the formwork being in contact; further saving storage space and reducing the required width for storage; at least two concave-shaped hinge sections 14231 are convenient for the concave-shaped multiple hinge sections to expand and elongate during subsequent rotation, facilitating the inner folding of the upper side formwork 1421 and avoiding being restricted by the length of the hinge section; the concave-shaped multiple hinge sections can store more lengths available for elongation; In this embodiment, the side formwork hinges 1423 are arranged in pairs as a group. The lengths of the first hinge support 14232 and the second hinge support 14233 are different. On the same first rib 145, the first hinge support 14232 of one side formwork hinge 1423 is arranged adjacent to the second hinge support 14233 of another side formwork hinge 1423. The two concave-shaped hinge sections 14231 are arranged staggeredly. More than half of one concave part is in the upper side formwork 1421; more than half of the other concave part is in the lower side formwork 1422. A common pin shaft 14234 is arranged through the intersecting part of the two concave parts.

[0083] With such a structure, the common pin shaft 14234 makes a circular motion around the hinge point of the longer hinge support, so that the unfolding of the concave multi-section hinge joint 14231 has a stable circular trajectory. Due to the existence of the common pin shaft 14234, while the multi-section hinge joint 14231 is unfolding, the common pin shaft 14234 therein also makes a circular motion at the same time, causing a stable rotation between the upper side mold 1421 and the lower side mold 1422.

[0084] The hinge joint 1031 of the common pin shaft 106 is in an obtuse V shape.

[0085] With such a structure, after the multi-section hinge joint 14231 is fully unfolded, when the hinge joint 14231 in an obtuse V shape encounters a right angle of the upper side mold 1421 or the lower side mold 1422, it can cross obliquely, thus avoiding rigid collision.

[0086] In this embodiment, it further includes a rotatable safety guardrail 15, which includes: Edge corbels 151, which are installed at intervals on the outer side of the truss beam 1 at the edge position; Flat plates 152, which are laid on the edge corbels 151; Railings 153, whose lower sides are hinged to the outer ends of the edge corbels 151; Railing hinge supports 154, which are fixed on the outer sides of the vertical poles of the railings 153; Link rods 155, whose upper ends are hinged to the railing hinge supports 154; Railing hydraulic jacks 156, which are horizontally fixed on the side of the truss beam 1, below the edge corbels 151; Piston end hinge supports 157, which are fixed on the piston ends of the hydraulic jacks and are hinged to the lower ends of the link rods 155; The railings 153 and the edge corbels 151 are hinged through railing hinge joints 158. The railing hinge joints 158 include railing rotating joints 1581 and corbel fixing joints 1582 sharing a common pin shaft. The railing rotating joints 1581 are fixed on the lower sides of the railings 153, and the corbel fixing joints 1582 are fixed on the outer ends of the edge corbels 151; The link rods 155 include a first body 1551 and a second body 1552. A first spring 1553 is arranged 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; Hoop fasteners 1554 are arranged on the first body 1551 and the second body 1552; limiting rods 1555 are slidably inserted through corresponding positions of the two hoop fasteners 1554.

[0087] Limit nuts 1556 are provided at both ends of the limit rod 1555, and a second spring 1557 is provided between the limit nut 1556 and the hoop 1554; 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.

[0088] With such a structure, by retracting the piston rod of the railing hydraulic jack 156, the connecting rod 155 rotates downward under the drive of the railing hydraulic jack 156, thereby driving the railing 153 to rotate, so that the railing 153 can be laid flat.

[0089] The railing hinge joint 158 allows the railing 153 and the edge bracket 151 to rotate relative to each other.

[0090] The split connecting rod can prevent the railing hydraulic jack 156 from applying too much pulling force, which is likely to 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.

[0091] The hoop 1554 can prevent the connecting rod 155 from bending; The second spring 1557 enables the limit rod 1555 to have a reset function; The reaction frame 1510 strengthens the fixation of the hydraulic jack 7; After the railing is laid flat, when performing the slip form operation subsequently, the railing can pass under the concrete beam.

[0092] In this embodiment, an angle steel 1511 is hinged to the end side of the railing 153. The angle steel 1511 can be flipped between the railing 153 and the edge bracket 151, and one of its limbs is opposite to the end face of the edge bracket 151, and a spacer 1512 is provided between one limb of the angle steel 1511 and the end face of the edge bracket 151.

[0093] A triangular reinforcement plate 1513 is provided between the two limbs of the angle steel 1511.

[0094] With such a structure, it can prevent the spring from pushing the railing 153 back, thus ensuring that the railing 153 is in a stable state.

[0095] The triangular reinforcement plate 1513 can strengthen the angle steel 10.

[0096] Embodiment 2 As Figures 1 - 19 shown, a construction method of a heavy cover plate construction machine specifically includes the following steps: S1: Install the construction machine. Along the already cast structural column, install the structural column embedded bracket 13, and install the lattice column 11 at intervals along the structural column; S2: Install the drop blocks 10 on the embedded corbels 13 of the structural columns and the lattice columns 11; S3: Lay parallel tracks 9 on the drop blocks 10; S4: Set a plurality of corresponding guide wheel moving components 8 at intervals on the tracks 9; S5: Install the truss beams 1 on the guide wheel moving components 8, and the truss beams 1 are installed at intervals, and an overhead layer 2 is formed at the interval; S6: Install the U-shaped frames 3 between the truss beams 1, and the installation position of the top surface of the U-shaped frames 3 should be lower than the top surface of the truss beams 1 to reserve space for stacking formworks; S7: Install hydraulic jacks 5 and slidable portal support frames 4 on the U-shaped frames 3, and the portal support frames 4 are fixed and propped up by the hydraulic jacks 5; S8: Install the detachable formwork assembly 14, and lay the bottom formwork 141 of the beam on the truss beam 1; install the side formwork 142 of the beam on the side of the bottom formwork 141 of the beam, and install the internal corner formwork 144 at the upper end of the side formwork 142; lay the bottom formwork 141 of the slab on the portal support frame 4, and the bottom formwork 141 of the slab is fixed and limited with the internal corner formwork 144; S9: Pour the concrete of the beam and slab.

[0097] In this embodiment, it further includes: S10: When demolishing the formwork, first release the fixed limit between the bottom formwork 141 of the slab and the internal corner formwork 144; S11: Start the hydraulic jack 5, demolish the bottom formwork 141 of the slab, and lower the bottom formwork 141 to the lower limit position, and convert it to the U-shaped frame 3 to support the portal support frame 4; S12: Release the fixed limit between the internal corner formwork 144 and the side formwork 142 of the beam, first demolish the internal corner formwork 144 and stack it on the bottom formwork 141 of the slab, and then demolish the side formwork 142 of the beam and stack it on the bottom formwork 141 of the slab; S13: Adjust the drop block 10 to lower the bottom formwork 141 of the slab to complete the formwork removal of the bottom formwork 141 of the slab; S14: All the truss beams 1 are moved on the tracks 9 through the guide wheel moving components 8 and pass below the beam bottom elevation, and are moved to the next construction section; S15: Adjust the drop block 10 to restore the bottom formwork 141 of the slab to the beam bottom elevation position and carry out the construction of this construction section.

[0098] As Figure 19 shown, legs can be set on the two embedded corbels 13 of the structural columns to erect double-ply I-beams, and then the drop blocks 10 are installed on the double-ply I-beams. The drop blocks are connected with wedge blocks by tie rods. By loosening and tightening the nuts, multiple drop blocks can be adjusted to the same elevation.
