Description

Technical Field

[0001] This utility model relates to the technical field of traction devices for dismantling auxiliary components of high-rise buildings, and in particular to a traction device for dismantling auxiliary components of high-rise buildings. Background Technology

[0002] With the increasing number of existing buildings, many buildings require demolition to accommodate new uses or for facade renovations. This is especially true for high-rise buildings, where demolition carries significant risks, necessitating safe and reliable support systems to secure the lowering devices.

[0003] Traditional demolition systems primarily use cranes and electric hoists to secure ropes. This method has a very low safety factor; even a slight sway can cause the system to become unstable. Furthermore, it requires space to operate, and large equipment is not suitable for all locations.

[0004] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0005] A traction device for removing ancillary components of a high-rise building includes a traction rope assembly and a cofferdam assembly, including a main cofferdam assembly and an auxiliary cofferdam assembly. The main cofferdam assembly is secured to the column by steel structure rods and bolts and laid on the floor surface. Chemical nails are also provided on the main cofferdam assembly to fix it to the floor surface to improve the connection strength. One end of the traction rope assembly is fixed to the end of the steel structure rod of the main cofferdam assembly. The auxiliary column assembly is used to strengthen the fixing strength of the device. There is at least one auxiliary column assembly located above or below the main column assembly. Alternatively, two auxiliary column assemblies can be located above and below the main column assembly, depending on the construction site conditions and actual requirements. A connecting rod is fixedly provided between the auxiliary column assembly and the main column assembly.

[0006] Furthermore, a stabilizing link is provided between the steel structural pole that connects to the traction rope assembly and the adjacent steel structural pole.

[0007] Specifically, it comprises a cantilever pole, a balance fixing pole, a lateral fixing pole, a closing pole, an upper diagonal tie rod, a lower support pole, pads, fixing bolts, and a traction device. The balance fixing pole includes a first reverse angle steel and a first anchor chemical anchor; the lateral fixing pole includes a reverse angle steel, an anchor chemical anchor, and a lateral support pole; the traction device includes a round hole, a steel seat, a hydraulic jack, and a steel wire rope.

[0008] Preferably, the cantilever rod, balance fixing rod, lateral fixing rod, and closing rod are fixed to the four sides of the building structure column using spacers and fixing bolts. One end of the upper diagonal tie rod is fixed to the upper closing rod with a fixing bolt, and the other end is fixed to the cantilever rod with a fixing bolt, serving a tying function; one end of the lower support rod is fixed to the lower closing rod with a fixing bolt, and the other end is fixed to the cantilever rod with a fixing bolt, serving a supporting function; the combined action of the upper diagonal tie rod and the lower support rod ensures the vertical stability of the cantilever rod. The lateral fixing rod ensures the horizontal stability of the cantilever rod.

[0009] Preferably, the main component of the cantilever pole is a finished H-beam, with the web of the H-beam horizontally placed and the flanges vertical. The flanges of the H-beam have several side holes, through which fixing bolts can be fixed to the lateral fixing rod, the upper diagonal tie rod, and the lower support rod. One end of the main component H-beam is fixed to a pad, which is a steel block with four evenly spaced holes. The pad can be welded to the H-beam, and the fixing bolts are fixed to the closing rod through the holes on the pad. The pad serves to support the connection between the cantilever pole and the closing rod. The use of finished H-beams facilitates material sourcing. The steel seat has a central hole, and two steel seat pieces are fixed to the upper and lower ends of one end of the cantilever pole, respectively, and can be fixed by welding. A hydraulic jack is fixed to the steel seat. A steel wire rope is connected to the hydraulic jack through the holes and traction through-holes, providing traction to the steel wire rope. The steel wire rope has high strength and toughness, allowing for the transport of various dismantled components and materials.

[0010] Preferably, one end of the lateral fixing rod is fixed to the cantilever rod via a pad and fixing bolts, and the other end is fixed to the reverse angle steel. The reverse angle steel has two round holes on each of its two sides. The vertical edge of the reverse angle steel is fixed to the lateral fixing rod via fixing bolts, and the horizontal edge is fixed to the floor level via anchor bolts, ensuring a stable connection between the lateral fixing rod and the high-rise building structure. One end of the lateral support rod is fixed to the lateral fixing rod, and the other end is fixed to the cantilever rod, forming a triangular stable support to ensure the horizontal stability of the cantilever rod. The main member of the balance fixing rod is still a finished H-beam, with one end fixed to the lateral fixing rod and the other end fixed to both sides with first reverse angle steel. The balance fixing rod is firmly fixed to the high-rise building floor level via first anchor bolts. The balance fixing rod is 1.5 times the length of the cantilever rod, which can balance the load generated by the traction device and has a certain safety margin. The closing rod is modularly produced and suitable for connections requiring closing rods, allowing each fixed position to be connected into a closed loop.

[0011] The advantages and positive effects of this utility model are: This utility model can be conveniently installed on any floor of a high-rise building. The triangular structure formed by vertical and horizontal directions provides stable support, ensuring that the traction device can be safely and stably dismantled and lowered.

[0012] This utility model uses simple and readily available materials, is easy to assemble on-site, has high construction efficiency, a high safety factor, can be reused multiple times, saves steel, and reduces costs. Attached Figure Description

The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings: Combination Figure 1-4 The present invention relates to a method for using a traction device for dismantling auxiliary components of a high-rise building. The first step is to conduct a risk assessment of the components that need to be demolished in the high-rise building, locate the floor, and check the surrounding conditions of the support points. The second step involves removing any adhering materials from the surface of the concrete column, fixing the 2 balance fixing rods to the floor level using the 22 first anchor chemical anchors, fixing the 3 lateral fixing rods to the floor level using the 32 anchor chemical anchors, and fixing the 4 closing rod and the 1 cantilever rod together to form a closed loop around the four sides of the concrete column. The 33 lateral support rod is then installed, and the connections of the 8 fixing bolts and the 22 first anchor chemical anchors are checked for secure fixation. Specifically, the 1 cantilever rod, 2 balance fixing rod, 3 lateral fixing rod, and 4 closing rod have 12 side round holes for connection with the 1 cantilever rod and the 8 fixing bolts. The 21 reverse angle steel is fixed to the end of the 2 balance fixing rod using the 8 fixing bolts and the 12 side round holes.

[0018] The third step is to take four 4-closed rods and fix the upper group of 4-closed rods to a certain position on the floor of the concrete column; take four 4-closed rods and fix the lower group of 4-closed rods to a certain position below the floor of the concrete column. The 4-closed rods are connected by 7 pads and 8 fixing bolts.

[0019] The fourth step involves fixing the upper and lower closing rods to the cantilever rod using the 5 upper diagonal tie rods and the 6 lower support rods, respectively.

[0020] Step 5: Install the traction device 9. Pass the 94 steel wire rope from bottom to top through the 92 steel seat with the 91 round hole and the 11 traction through hole, and fix the upper end of the 94 steel wire rope in the 93 hydraulic jack. The two 92 steel seat pads with the 91 round holes are respectively set at the upper and lower ends of the 1 cantilever rod. Check the installation stability and the firmness of the connection of each part. After the inspection is completed, remove the component and start the traction and lowering operation. Monitor the stress of the 94 steel wire rope in real time during the lowering.

[0021] Step 6: After the dismantling work is completed, dismantle the utility model device in the reverse order of installation. Store and organize it for future use.
