[0049] Example 1

[0050] like Figure 1-Figure 27 As shown, a construction method of a concrete plant assembly plant machine supporting system comprises the following steps:

[0051] S1: Use the side wall and side column formwork system to construct the side wall and side columns 5 around the workshop along the outer edge of the grid. After removing the formwork, reserve door openings on the side walls, install the side lifting point embedded parts along the outer grid points and lines, and install the side brackets along the grid lines perpendicular to the side wall and side columns;

[0052] S2: Install the early demolition support system 1, which is divided into an early demolition support column base system 101 and an early demolition support column system 102 installed on the early demolition support column base system 101; the early demolition support column base system 101 is arranged according to grid points, and inner corbels are installed on the early demolition support column system 102 along the grid line direction; so that two groups of relatively spaced corbels are formed along the grid line longitudinally and transversely;

[0053] S3: Install the truss platform system 3, and lay the split single-piece truss platform on the ground between the relatively spaced corbels along the longitudinal and transverse directions of the grid;

[0054] S4: Install a lifting system 4 on the corbel, and use the lifting system to lift the single-piece truss platform. After the single-piece truss platform is lifted to the height of the corbel, it is spliced ​​with the corbel to form a truss platform at this workstation;

[0055] S5: Set up the roof formwork system on the truss platform, and remove the formwork after constructing the roof of the factory building at this station;

[0056] S6: placing parts of the transfer trolley system 2 under the single-piece truss platform, disassembling the single-piece truss platform piece by piece, lowering the single-piece truss platform to the installation position of the transfer trolley system 2, installing the transfer trolley system 2 at the bottom of the single-piece truss platform, and transporting it to the next workstation or door opening by the transfer trolley system 2;

[0057] S7: After completing the construction of all the workstation roofs 6, the early dismantling support system 1 is dismantled.

[0058] The early removal support column base system 101 comprises:

[0059] Transverse I-beams 10101 are laid in parallel intervals;

[0060] The longitudinal I-beams 10102 are laid in parallel at intervals and are vertically fixed between two adjacent parallel transverse I-beams 1, and form a closed area with the transverse I-beams 1;

[0061] A cross-shaped I-beam 10103, which is disposed inside the closed area and has its ends fixed to the transverse I-beam 10101 and the longitudinal I-beam 10102;

[0062] The triangle plate 10104 is welded to the corner of the upper flange in the middle of the cross-shaped I-beam 10103, and a gap is reserved between the triangle plate 10104 and the transverse I-beam 10101, and between the triangle plate 10104 and the longitudinal I-beam 10102;

[0063] The backing plate 10105 is placed in the middle of the cross-shaped I-beam 10103 and covers the triangular plate 10104, with a space reserved between the backing plate 10105 and the transverse I-beam 10101 and the longitudinal I-beam 10102;

[0064] The first bolt and nut assembly 10106 penetrates the backing plate 10105 and the triangular plate 10104 and is tightened, with the bolt head at the upper end and the nut at the lower end.

[0065] The positioning ribs 10107 are fixedly arranged on the pad 10105 at an annular spacing angle.

[0066] With such a structure, the positioning rib 10107 facilitates the positioning of the early-removal support column. The lower end of the early-removal support column has a flange plate connected to the positioning rib. The triangular plate 10104 can prevent the first bolt and nut assembly 10106 from drilling holes in the cross-shaped I-beam 10103, thereby preventing the cross-shaped I-beam 10103 from reducing the bearing capacity of the cross-shaped I-beam 10103. Intervals are reserved between the triangular plate 10104 and the transverse I-beam 10101, as well as between the triangular plate 10104 and the longitudinal I-beam 10102, so as to reserve sufficient space for the installation and removal of the first bolt and nut assembly 10106. The positioning rib 10107 positions the early-removal support column and is also convenient for welding with the early-removal support column.

[0067] In this embodiment, a first rib 10108 is provided in the transverse I-beam 10101 and the longitudinal I-beam 10102 .

[0068] With such a structure, the first rib 10108 strengthens and supports the transverse I-beam 10101 and the longitudinal I-beam 10102 .

[0069] In this embodiment, a first ear plate 10109 is provided on the transverse I-beam 10101 and the longitudinal I-beam 10102 .

[0070] With such a structure, it is convenient to support the inclined pull rod 10110 on the first ear plate 10109 .

[0071] In this embodiment, a pull rod 10110 is hinged on the first ear plate 10109 .

[0072] With such a structure, the pull rod 10110 is convenient for hinged early dismantling of the root of the support column.

[0073] In this embodiment, a triangular block 10111 is arranged between the cross-shaped I-beam 10103 and the pad 10105. The triangular block 10111 is located on two coaxial branches of the cross-shaped I-beam 10103. A pair of triangular blocks 10111 are connected by tension screws 10112 and are tightened with a first nut 10113 and a gasket 10114. The pad 10105 abuts against the inclined surface of the triangular block 10111.

[0074] Such a structure makes it easier to remove the root of the early-removal support column during subsequent disassembly, so that the disassembly efficiency is improved.

[0075] In this embodiment, rails 10115 are provided on both sides of the triangular block 10111 , and the rails 10115 are welded to the branches of the cross-shaped I-beam 10103 .

[0076] Such a structure makes it easy for the triangular block 10111 to retreat along a predetermined route when the supporting column is removed early.

[0077] In this embodiment, the triangular block 10111 is inserted into the rib 16 , and the rib 10116 passes through a pair of triangular blocks 10111 and is placed under the pad 10105 .

[0078] With such a structure, when disassembling the early disassembly support column, first pull out the rib 10116 and then remove the early disassembly support column, and the rib 10116 is convenient for supporting the middle part of the pad 10105.

[0079] In this embodiment, a groove 10117 is provided on the outer side of the rib 10116 to insert the side rib 10118 .

[0080] With such a structure, the side ribs 10118 are placed on the sides of the pad 10105 to better support the pad 10105 , and the grooves 10117 facilitate positioning of the side ribs 10118 .

[0081] In this embodiment, a middle rib block 10119 is arranged between the two ribs 10116 , and a U-shaped groove 10120 is provided on the upper surface of the middle rib block 10119 for the tension screw 10112 to pass through, and the upper surface of the middle rib block 10119 is spaced apart from the lower surface of the pad 10105 .

[0082] With such a structure, after the pad 10105 is removed, it is supported by the middle rib 10119.

[0083] In this embodiment, a groove 10121 is formed on the bottom surface of the triangular block 10111 , and rollers 10122 are distributed in the groove 10121 .

[0084] With such a structure, the bottom surface of the triangular block 10111 is easy to slide, thereby reducing the friction during unloading.

[0085] First, the early removal support column base system 101 is removed, and then the early removal support column system 102 and the early removal support column base system 101 are removed from bottom to top. The specific steps are as follows:

[0086] When the early dismantling support column is dismantled in sections, the flanges of the middle section steel column and the top section steel column are first unbolted, and then the early dismantling support column base system 101 is used to complete the unloading operation, so that a gap is reserved between the middle section steel column and the top section steel column, and then the bolts of the middle section steel column and the bottom section steel column are unbolted, and then the middle section steel column is lifted out, and then the top section steel column and the bottom section steel column are dismantled. After the gap is reserved, the middle section steel column and the top section steel column will not get stuck, so as to prevent the middle section steel column from being pushed up against the top section steel column when dismantling, which may damage the bottom surface of the roof, or may cause the top section steel column to shake, affecting construction safety, or when the base is dismantled first, the lower section of the middle section steel column is vacant and is easy to swing in the wind. The longer the length, the greater the swing amplitude, which may put construction workers in danger during dismantling. If the middle section steel column is dismantled first, each section of the steel column will be relatively short, and the swing amplitude in the wind will be small, which is safer during dismantling.

[0087] The early removal support column system 102 of this embodiment includes:

[0088] The multi-section steel column 10201 is arranged in upper and lower sections and spliced;

[0089] A flange 10202 is fixedly mounted on the end of the single-section steel column 10201;

[0090] A reinforcing plate 10203, which is welded between the steel column 10201 and the flange 10202;

[0091] Corbel 10204, which is fixedly connected to both sides of the top section steel column 10201;

[0092] Bolt and nut assembly 10205, which is fastened to the adjacent spliced ​​flange 10202;

[0093] A first clamp 10206, which is fixed on the bottom steel column 10201;

[0094] The second ear plate 10207 is arranged on the first clamp 10206.

[0095] With this structure, multiple sections of steel columns 10201 are spliced ​​up and down through flanges 10202 and bolt and nut assemblies 10205, which is convenient for disassembly and assembly. The first clamp 10206 is fastened to the bottom steel column 10201.

[0096] In this embodiment, a first hanging ring 10208 is distributed on the steel column 10201.

[0097] With such a structure, when the steel column 10201 is disassembled in sections, the first lifting ring 10214 cooperates with the lifting rope to facilitate the disassembly and lowering of the segmented steel column 10201.

[0098] In this embodiment, the corbel 10204 includes an upper chord 102401, a lower chord 102402, a vertical web 102403 and a diagonal web 102404. The first bottom plate 102405 is fixed to the end of the upper chord 102401 and the lower chord 102402 close to the steel column 10201, and the second bottom plate 102406 is fixed to the end away from the steel column 10201. The first bottom plate 102405 is fixed to the steel column 10201.

[0099] With such a structure, the first base plate 102405 and the second base plate 102406 are used to splice the steel column 10201 and the truss respectively.

[0100] In this embodiment, a sealing ring 10209 is arranged between adjacent flanges 10202 .

[0101] Adopting such a structure is beneficial to waterproofing the interior of steel column 10201.

[0102] In this embodiment, the lower chord 102402 is shorter than the upper chord 102401 , and the second suspension ring 102407 is fixedly connected to the portion of the upper chord 102401 that exceeds the lower chord 102402 .

[0103] With such a structure, the second lifting ring 102407 facilitates lifting the truss, and the lower chord 102402 is shorter than the upper chord 102401, which does not affect the verticality of the pull rope during the lifting process.

[0104] In this embodiment, the rib plate 102408 is welded to the first bottom plate 102405 and the second bottom plate 102406, the rib plate 102408 is fixedly connected to the first bottom plate 102405 and the upper chord 102401, and the rib plate 102408 is also fixedly connected to the first bottom plate 102405 and the lower chord 102402; the rib plate 102408 is also fixedly connected to the second bottom plate 102406 and the upper chord 102401, and the rib plate 102408 is further fixedly connected to the second bottom plate 102406 and the lower chord 102402.

[0105] With such a structure, the rib plate is welded to the first bottom plate and the upper chord, and the rib plate is also welded to the first bottom plate and the lower chord to stabilize the corbel.

[0106] With such a structure, the rib plate 102408 is welded to the first bottom plate 102405 and the upper chord 102401 and then to the steel column 10201. The rib plate 102408 is also welded to the first bottom plate 102405 and the lower chord 102402 and then to the steel column 10201 to stabilize the corbel 10204.

[0107] In this embodiment, the tension screw assembly 10210 is connected to the first bottom plate 102405, and the tension screw assembly 10210 is connected to the steel column 10201 and the first bottom plates 102405 on both sides thereof.

[0108] By adopting such a structure, the bearing capacity of the upper corbel of steel column 10201 is higher.

[0109] In this embodiment, partitions 10211 are provided in the top steel column 10201. The partitions 10211 are welded in layers in the top steel column 10211 and are located below and above the tension screw assembly 10210. Holes are opened in the upper partitions 10211 and concrete is poured to make them dense.

[0110] With such a structure, the deformation of concrete due to thermal expansion and contraction is small, and after pouring, the tension screw assembly 10210 is further strengthened to prevent it from loosening.

[0111] In this embodiment, the first clamps 10206 are arranged in layers, and the first screw 10212 is fixed between the upper and lower first clamps 10206. The first screw 10212 is slidably connected to the second ear plate 10207, and the second ear plate 10207 is threadedly connected to the second nut 10213 on the upper and lower sides.

[0112] With such a structure, the tightness of the pull rod can be adjusted to ensure that it is in a tight state during use.

[0113] In this embodiment, a horizontal plate 10214 is arranged inside the column head of the top section steel column 1, a vertical plate 10215 is fixedly connected to the horizontal plate 10214, a cover plate 10216 is fixedly connected to the vertical plate 10215, and concrete is poured densely between the horizontal plate 10214 and the cover plate 10216.

[0114] With such a structure, it is convenient to install the bracket on the cover plate 10216, and the vertical plate 10215 prevents the cover plate 10216 from being concave, so that the deformation is smaller after pouring the concrete.

[0115] In this embodiment, the bottom section of the steel pipe column is convenient for connection with the base, and is convenient for pre-fixing the bottom section of the steel pipe column before welding or bolting, which is beneficial to improving construction efficiency, improving the quality of welding or bolting, and ensuring that the steel column is vertical during the fixing process to prevent tilting.

[0116] The truss platform system 3 used in this embodiment includes:

[0117] The main trusses 301 are arranged in parallel at intervals;

[0118] The secondary truss 302 is arranged vertically and crosswise with the main truss 301, and its upper and lower chords are made of square steel pipes. Positioning sleeves 30201 are fixed in the ends of the square steel pipes. The positioning sleeves 30201 are pressed against the upper and lower sides of the ends of the square steel pipes. The third bolt and nut assembly 305 is passed through the positioning sleeves. The third bolt and nut assembly 305 is tightened on the upper and lower sides of the ends of the square steel pipes.

[0119] The first splicing plate 303 is fixed to the upper chord and the lower chord of the secondary truss 302, one end of which is built into the square steel tube and is pressed against the side of the positioning sleeve 30201;

[0120] The second clamp 304 is fixed at intervals on the upper chord and the lower chord of the main truss 301 , and a second splicing plate 30401 is arranged on its side and is fixed to the first splicing plate 303 through a fourth bolt and nut assembly 306 .

[0121] By adopting such a structure, the position of the second clamp 304 on the main truss 301 can be adjusted and then tightened.

[0160] The lifting system used in this embodiment is:

[0161] 1. Lifting principle

[0162] The lifting system of this embodiment uses an electric hoist as the lifting power. The upper hook of the electric hoist is installed on the corbel at the upper end of the support column removed early on the inner side of the wall column, and the lower hook of the electric hoist is hooked on the lifting point of the lower chord of the main truss of the truss platform. The chain is driven by the electric hoist to make the truss platform move up and down relatively, thereby realizing the lifting function. After each lifting is completed, the electric hoist is transferred to the next lifting platform unit to prepare for the next lifting.

[0163] The lifting system 4 in this embodiment includes:

[0164] The intelligent master control box is connected to the main power line, and the power output line and the communication line are connected. The power output line is connected to the surrounding branch cable, and multiple extension power lines are configured on the surrounding branch cable, and multiple branch communication lines are configured on the communication line;

[0165] Intelligent extension, which is connected to the extension power line and branch communication line, and connected to the hoist power line;

[0166] Electric hoist, which is connected to the hoist power line and installed on the corbel;

[0167] The gravity sensor is arranged on the hanging point of the electric hoist and is electrically connected to the intelligent extension.

[0168] Among them, there is 1 intelligent master control box, which issues raising, lowering, stopping and other commands to the intelligent extensions.

[0169] Intelligent extension: n units (Note: n represents the number of positions, and a maximum of 100 intelligent extension units can be controlled). The real-time load data of each position is collected and comprehensively analyzed to identify various faults and make corresponding automated operations in a timely manner, such as early warning and shutdown.

[0170] Gravity sensor: n sets (Note: n represents the number of positions)

[0171] With 5-core shielded cable and 5-core aviation socket: It is the direct bearer of the aircraft suspension point load. It measures the load in real time and generates corresponding analog signals for collection by the single-chip microcomputer of the intelligent extension.

[0172] Surround branch cable: It adopts bus control mode, connects multiple communication lines, connects each intelligent extension together, and surrounds one branch cable.

[0173] The lifting system is also equipped with an alarm device

[0174] Alarm mode: buzzer alarm, color-changing light displays three alarm colors: red, yellow, and blue.

[0175] When the load value collected at a certain position exceeds the design value by 15%, an automatic alarm should be given in the form of sound and light. When it exceeds 30%, the electric hoist should be able to stop automatically.

[0176] Unload value alarm (SR1): When the load value collected in each position is less than the unload value, the intelligent extension and the intelligent main control box will send out intermittent alarm sounds (short sounds) and display the weight of the heavy object on the corresponding display.

[0177] Overload value alarm (SR2): When the maximum load value collected by each position reaches the overload value, the intelligent extension and the intelligent main control box will send out intermittent alarm sounds (long sounds) and display the weight of the heavy object.

[0178] Overload limit value alarm (SR3): When the load value collected by any machine position reaches the overload limit value, the intelligent extension and the intelligent master control box will issue a continuous alarm sound, and within 1 second, the relay output switch signal of the intelligent master control box will cut off the main control circuit, and the PC will display the status of each machine position when the cut-off occurs.
