At the same time, because the functional design of buildings cannot meet the current use requirements, more and more buildings need to be rebuilt or expanded, and the number of renovation and expansion projects of old buildings is also increasing. If the traditional ordinary construction method is used to demolish and reconstruct the original low-height buildings, there will be many construction problems. Not only is it limited by the effective construction deployment space, it is impossible to use large-scale demolition equipment, and it can only be demolished by traditional impact drills and cutting machines. The construction is difficult, the construction safety is not guaranteed, and the construction efficiency is low, and the labor intensity of the construction workers is very high. In addition, the use of traditional demolition construction equipment can easily cause collateral damage to the building, such as destroying the beam-column structure that is not demolished, cracking the floor slab that is not demolished, etc., which is not conducive to the overall structural safety of the building, and the support cost of the demolition process is high. The support and support of traditional steel pipe scaffolding is not only cumbersome in the installation and disassembly process, but also occupies a large amount of indoor space, which is not conducive to the cleaning and transportation of demolished components. After the demolition components are dismantled and separated, they need to be hoisted with the assistance of human labor. Multiple construction workers are needed on site to complete the fixing and hoisting of the prefabricated components. The hoisting process is relatively inefficient. The demolition components in a suspended state are heavy. For some demolition components that have been partially broken or cracked during the demolition process, it poses a relatively large safety hazard to the operators. It can be seen that this traditional floor demolition operation method has the problems of low automation, difficulty in demolition construction in limited indoor space, difficulty in hoisting, high labor intensity, and is not conducive to the overall structural safety of the building.

[0048] a. First, arrange the supporting steel frame 4 on the ground layer 1, and install the lifting frame 9 between two adjacent supporting steel frames 4, so that the lifting frame 9 is located directly below the floor to be demolished, and the supporting steel frame 4 is firmly supported by the telescopic legs 6, and the floor support 7 is used to support the floor or beam outside the floor to be demolished;

[0049] b. Then, the load-bearing frame 14 is installed on the lifting frame 9, and the cutting equipment and its accessories are prepared, and the floor slabs to be demolished are marked in the order of demolition;

[0050] c. Control the height adjustment hydraulic cylinder 8 to extend upward by a certain distance, so that the lifting frame 9 rises to a certain height to ensure that the load-bearing frame 14 can carry the floor slab or beam to be removed from the bottom;

[0051] d.

[0052] e. Immediately start the transverse moving device and the longitudinal moving device, and with the help of the laser calibrator 42, respectively drive the transverse cutting machine 24 and the longitudinal cutting machine 31 to move to the right below the floor cutting mark, and control the saw blades of the cutting machines to align with the cutting mark;

[0053] f. After starting the cutting machine, control the saw blade height adjustment device to drive the cutting machine to move upward a certain distance. After starting cutting, the cutting machine moves along the slide rail and moves and cuts according to the cutting mark;

[0054] g. After completing two parallel transverse cutting seams and two longitudinal cutting seams of each floor slab, start the impact hammer and hammer from bottom to top, so that the cut floor slab falls to the upper end of the elastic support member under the action of gravity, and falls on the floor slab placement surface 16 after being buffered by the elastic support member;

[0055] h. Finally, the vertical lifting device 15 is controlled to drive the load-bearing frame 14 to move downward to the bottom of the lifting frame 9. At the same time, the height adjustment hydraulic cylinder 8 is controlled to drive the lifting frame 9 to move downward, completing the removal and downward transportation of a single floor slab, thereby increasing the building's floor height.

[0056] See also Figures 1 to 5 The present invention adopts a multi-section combined support structure composed of a supporting steel frame 4, a height-adjusting hydraulic cylinder 8, a lifting frame 9 and a vertical lifting device 15, which can not only provide effective support for the floor to be demolished, ensure the structural safety of the demolished building, and effectively avoid the cracking of the floor or beam components that are not demolished, but also can move and adjust the support position according to the construction position, and no longer use steel pipes to set up fixed scaffolding. At the same time, it can also automatically transport the cut and demolished floor and other building components to the ground or transfer equipment, without the need for construction workers to climb and hoist assistance, thus avoiding the safety risks of suspended hoisting.

[0057] The present invention adopts a support steel frame 4 placed on the ground layer 1. As a ground support structure, the height of the support steel frame 4 is not less than half of the existing building layer height and is lower than the building layer height. The support steel frame 4 is used in a plurality of spliced ​​combinations. The splicing is performed horizontally on the ground according to the size of the floor demolition area. At the same time, the support steel frames 4 are arranged in pairs in parallel, and the top of the area between two adjacent parallel support steel frames 4 faces the floor to be demolished.

At the same time, telescopic legs 6 are installed at the four corners or multiple stress-bearing parts of the bottom of the support steel frame 4. The telescopic legs 6 can adopt a commonly used screw-type adjustment structure. When the support steel frame 4 needs to be moved, the telescopic legs 6 are retracted so that the bottom of the telescopic legs 6 is separated from the ground and the steel rollers 5 are in contact with the ground; when the movement is completed and fixed support is required, the telescopic legs 6 are put down so that the bottom of the telescopic legs 6 is supported on the ground. In addition, a floor support 7 is provided on the top of the supporting steel frame 4. The floor support 7 is a small hydraulic cylinder, a jack or other supporting structure, which is used to support the floor or beam on the outside of the floor to be demolished from the bottom. It can not only support the floor or beam on the outside of the floor to be demolished, but also improve the stability of the supporting steel frame 4 to avoid overturning.

[0058] A lifting frame 9 is installed between two parallel supporting steel frames 4, and the lower end of the lifting frame 9 extends to the lower part of the two parallel supporting steel frames 4. The lifting frame 9 is made of steel structure, and the upper end width of the lifting frame 9 is greater than the spacing between the two supporting steel frames 4 on which the lifting frame 9 is installed, and the lower part width of the lifting frame 9 is less than the spacing between the two supporting steel frames 4 on which the lifting frame 9 is installed, so that it is convenient for the upper end of the lifting frame 9 to be installed on the supporting steel frames 4. A height adjustment hydraulic cylinder 8 is installed between the upper end of the supporting steel frame 4 and the upper four corners of the lifting frame 9, and the synchronous extension and contraction of the four height adjustment hydraulic cylinders 8 can drive the lifting frame 9 to rise and fall. The front and rear ends of the lower part of the lifting frame 9 are horizontally connected with a bottom cross beam 12, and a groove is opened at the upper end of the bottom cross beam 12. A long single roller 13 or a plurality of coaxially arranged rollers 13 are installed in the groove. The upper rim of the roller 13 is higher than the upper plane of the bottom cross beam 12. The function of the roller 13 is to facilitate the bottom of the floor slab to be placed on the roller 13 and slide outward during the transportation of the cut and removed floor slab to the outside, which saves labor and effort, and the transportation can be completed inside the building by manpower or small lifting equipment.

[0059] The bottom left and right sides of the lifting frame 9 are provided with mutually parallel horizontal slide rails 10, which are distributed along the length direction of the supporting steel frame 4. The horizontal slide rails 10 are installed with a sliding seat 11, and the sliding seat 11 is installed with a vertical lifting device.

The upper surface of the bearing frame 14 is a floor slab placement surface 16. The bottom of the disassembled floor slab can be placed on the floor slab placement surface 16, and can carry the disassembled floor slab, and support the cut and disassembled floor slab as a whole from the bottom. An impact hammer is installed on the bottom of the load-bearing frame 14, the transverse moving frame 21 or the longitudinal moving frame 28. The impact hammer is an existing commonly used electric tool. The impact hammer can be an electric impact hammer. The impact hammer head of the impact hammer 35 is facing the bottom of the demolished floor inside the cutting seam of the floor. After the floor is cut, the impact hammer 35 is used to impact the floor to a certain extent, so that the floor falls by itself under the action of gravity. A plurality of mounting holes 17 are provided on the floor shelf surface 16. The mounting holes 17 are distributed at the four corners of the floor shelf surface 16 and a plurality of equally spaced force-bearing positions. An elastic support member that can temporarily support and buffer the floor is installed in the mounting hole 17. The role of the elastic support member is to temporarily support when the floor is cut and removed, and to buffer when the floor falls under the action of gravity, so as to avoid the sudden fall of the demolished floor to generate a huge impact force on the equipment, resulting in the breakage of the floor and the generation of splashing fragments.

[0060] The bottom of the load-bearing frame 14 is respectively installed with a transverse moving frame 21 and a longitudinal moving frame 28, which may also be a long strip moving beam structure. The transverse moving frame 21 and the longitudinal moving frame 28 are on different horizontal planes and are vertically distributed. The transverse moving frame 21 is installed at the bottom of the load-bearing frame 14 through a transverse slide rail or a transverse slide groove, and the longitudinal moving frame 28 is installed at the bottom of the load-bearing frame 14 through a longitudinal slide rail or a longitudinal slide groove. A transverse moving device is installed between the load-bearing frame 14 and the transverse moving frame 21, and the transverse moving device drives the transverse moving frame 21 to move back and forth along the transverse direction at the bottom of the load-bearing frame 14. Similarly, a longitudinal moving device is installed between the load-bearing frame 14 and the longitudinal moving frame 28, and the longitudinal moving device drives the longitudinal moving frame 28 to move back and forth precisely along the longitudinal direction at the bottom of the load-bearing frame 14.

[0061] The transverse moving device and the longitudinal moving device can adopt the same structure, which has various structural forms, for example: a moving device driven by a screw, a moving device driven by a gear rack, etc. When a moving device driven by a screw is adopted, it mainly includes a screw 25, a servo motor 26 and a screw nut 27. The screw 25 on the transverse moving device is arranged horizontally on a horizontal plane. One end of the screw 25 is installed on the supporting frame 14 through a screw bearing seat, and the other end of the screw 25 is coaxially fixed with the rotating shaft of the servo motor 26.
