[0002] This invention was developed to safely disassemble the building construction machine manufactured by our company. Summary of the Invention
[0003] This invention addresses the shortcomings of existing technologies by designing a safe dismantling method for building construction machines. The method involves fixing the inner and outer large formwork to the building walls using hanging anchor points and the frame using fixed anchor points. Then, the building construction machine is dismantled using a sequential dismantling method from the outside to the inside and from top to bottom. The dismantling method is safe and reliable.
[0004] The technical solution disclosed in this invention is as follows: A method for the safe dismantling of a building construction machine, the first step being: before the completion of the building construction machine's construction task, embedding anchor points for the hoisting and fixing of each frame and formwork in the building structure.
[0005] (1) Pre-embed large formwork hanging points at the top of the roof layer. Each set of large formwork shall have at least two hanging anchor points.
[0006] (2) Install the scaffolding anchor points on the roof floor -1 level;
[0007] Step 2: Before dismantling the building construction machine, first fix the large formwork and inner frame to the corresponding anchor points using steel wire ropes.
[0008] (1) Except for the large formwork on the outside of the building structure, all other large formwork is fixed to the hanging anchor points on the top of the roof layer by steel wire rope.
[0009] (2) Secure all inner frames with steel wire ropes at the roof level -1, and install a limiting support frame structure on the inner side of the inner frames to ensure the stability of the inner frames.
[0010] (3) After the large formwork and inner frame are firmly fixed, remove the connection between the large formwork, inner frame and the top construction platform;
[0011] The building was dismantled and constructed sequentially from the outside to the inside and from top to bottom.
[0012] Based on the above scheme, as a preferred option, the dismantling and reconstruction of the building machine from the outside to the inside and from top to bottom specifically includes:
[0013] Step 3: Dismantle the hydraulic and electrical equipment on the construction platform;
[0014] Step 4: Removal and implementation of equipment attached to the top platform;
[0015] Step 5: Dismantle the outer scaffolding. First, loosen the bolts connecting the outer scaffolding platform beams to the main and secondary beams. Then, use a tower crane to lift the outer scaffolding sections to the ground for dismantling.
[0016] When dismantling the outer formwork, first hang the wire rope, then slowly lift the hook of the tower crane until the wire rope is taut and stops. Release the formwork fixing connection, and after checking that everything is correct, lift the hook to the ground.
[0017] Step 6: Remove and stack the top platform slabs, then lift them to the ground by a tower crane;
[0018] Step 7: When dismantling the inner formwork, first hang the wire rope, and slowly lift the hook of the tower crane until the wire rope is taut and stops. Release the fixing connection of the inner formwork, and after checking that everything is correct, lift the hook to the ground.
[0019] Step 8: Install the inner frame hoisting equipment, attach the wire rope, and slowly lift the hook of the tower crane until the wire rope is taut and stops. Remove the bolts at the connection points between the upper and lower frames and the uprights. Check all connections to ensure they are disconnected before lifting the hook to the ground.
[0020] Step 9: Use a tower crane to lift the upper part of the guide rail, then slowly pull it out from the wall-mounted support and hoist it to the ground;
[0021] Step 10: After removing the hanging boots, secure them to the lower frame using wire;
[0022] Step 11: Install the lifting equipment for the lower frame, attach the wire rope, and slowly lift the hook of the tower crane until the wire rope is taut and stops. Remove the wire rope that is fixing the lower frame, check all connection points to ensure that they are disconnected, and then lift the hook to the ground for disassembly, packaging, and loading.

[0032] Remove the bolts connecting the base of the concrete placing boom to the frame, then use a tower crane to lift it to the ground for loading and loading onto a truck. Use four steel wire ropes to secure the concrete placing boom during lifting. Lift slowly and steadily to avoid collisions with other objects.
[0033] Based on the above scheme, as a preferred option, the loose items in step six are collected in the hoisting hopper and then lifted to the ground by the tower crane.
[0034] Based on the above scheme, as a preferred option, in the ninth step, the tower crane uses two steel wire ropes to lift the upper part of the guide rail, and the lifting should be slow and stable.
[0035] Based on the above scheme, as a preferred option, large movable objects that need to be hoisted together with the lower frame in step eleven must be rigidly connected and fixed to the lower frame to prevent them from wobbling before they can be hoisted.

[0055] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.
[0056] like Figure 1-16 As shown, a method for the safe dismantling of a building construction machine frame is as follows: First step: Before the completion of the building construction machine's construction task, anchor points are embedded in the building structure for the hanging and fixing of each frame and formwork. The large formwork 7 and the frame are fixed to the building structure using Ø16 steel wire rope 2. The frame includes the outer frame 5 and the inner frame 6.
[0057] (1) Pre-embed large formwork hanging points at the top of the roof layer. Each group of large formwork should have at least two hanging anchor points. The hanging anchor points are pre-embedded at the top, such as... Figure 1-2As shown, the U-shaped component 1 has two ends bent outwards to improve the fixing effect after pre-embedding;
[0058] (2) Install anchor points for scaffolding on the roof level -1, such as Figure 3-5 As shown, the fixed anchor point is pre-embedded in the form of machine position fixed climbing cone 3, and then the fixed lifting ring 4 is fixed on the climbing cone. The fixed lifting ring is V-shaped and the angle is between 160-170.
[0059] Step 2: Before dismantling the building construction machine, first fix the large formwork and inner frame to the corresponding anchor points using steel wire ropes.
[0060] (1) Except for the large formwork on the outside of the building structure, all other large formwork is fixed to the hanging anchor points on the top of the roof layer by steel wire rope.
[0061] (2) Secure all inner frames with steel wire ropes at the roof level -1, and install limiting support frames on the inner side of the inner frames to ensure their stability. The limiting support frames are L-shaped, such as... Figure 6 As shown, one right-angled side is fixed to the inner frame, and a roller is installed at the end of the other right-angled side. The roller contacts and engages with the wall.
[0062] (3) After the large formwork and inner frame are firmly fixed, remove the connection between the large formwork, inner frame and the top construction platform;
[0063] The building was dismantled and constructed sequentially from the outside to the inside and from top to bottom.
[0064] The specific steps of dismantling and rebuilding a building from the outside in and from top to bottom include:
[0065] Step 3: Dismantle the hydraulic and electrical equipment on construction platform 9:
[0066] (1) Disconnect the power supply and remove the cable;
[0067] (2) Disconnect the quick connector between the small oil pipe and the cross distributor, and remove the cross distributor and the main oil pipe;
[0068] (3) When disconnecting the small oil pipe, cross distributor and main oil pipe, cover the protective cover of the quick coupling;
[0069] (4) The dismantled oil pipes were packed up, hoisted to the ground, and boxed.
[0070] (5) The hydraulic power cabinet is lifted to the ground.
[0071] Step 4: Dismantle the equipment attached to the top platform, including the concrete placing boom 8, the tool shed, and dismantle the inner large formwork hoist and the connection between the outer frame and the top platform.
[0072] Remove the bolts connecting the base of the concrete placing boom to the frame, then use a tower crane to lift it to the ground for loading and loading onto a truck. Use four steel wire ropes to secure the concrete placing boom during lifting. Lift slowly and steadily to avoid collisions with other objects.
[0073] Step 5: Dismantle the outer scaffolding. First, loosen the bolts connecting the outer scaffolding platform beams to the main and secondary beams. Then, use a tower crane to lift the outer scaffolding sections to the ground for dismantling.
[0074] When dismantling the outer formwork, first hang the wire rope, then slowly lift the hook of the tower crane until the wire rope is taut and stops. Release the formwork fixing connection, and after checking that everything is correct, lift the hook to the ground.
[0075] Step 6: Remove and stack the top platform panels, collect loose items in the hoisting hopper, and then lift them to the ground by the tower crane;
[0076] Step 7: When dismantling the inner formwork, first hang the wire rope, and slowly lift the hook of the tower crane until the wire rope is taut and stops. Release the fixing connection of the inner formwork, and after checking that everything is correct, lift the hook to the ground.
[0077] Step 8: Install the inner frame hoisting equipment, attach the wire rope, and slowly lift the hook of the tower crane until the wire rope is taut and stops. Remove the bolts at the connection points between the upper and lower frames and the uprights. Check all connections to ensure they are disconnected before lifting the hook to the ground.
[0078] Step 9: Use a tower crane to suspend the upper part of the guide rail. The tower crane uses two steel wire ropes to lift the upper part of the guide rail. The lifting should be slow and stable. Then slowly pull it out from the wall support and lift it to the ground.
[0079] Step 10: After removing the hanging boots, secure them to the lower frame using wire;
[0080] Step 11: Install the lifting equipment for the lower frame, attach the wire rope, and slowly lift the hook of the tower crane until the wire rope is taut and stops. Remove the wire rope fixing the lower frame, check all connection points to ensure that they are disconnected, and then lift the hook to the ground to disassemble, pack, and load the truck. Large movable objects that need to be lifted together with the lower frame must be rigidly connected and fixed to the lower frame to prevent them from shaking before they can be lifted.
[0081] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
