Abstract
The invention provides steel wire rope symmetrically disassembling process flow for tower crane attachment device and relates to the technical field of constructional engineering. The process flow comprises the following steps: disassembling a wall attached device on the side of a lifting arm by using a crampon; disassembling the attached wall on the side of a balancing arm by a back rolling symmetrical steel wire rope device; and clearing and inspecting mechanical parts. The process flow is safe, practical, scientific and efficient and can guarantee construction safety and avoid the damage on the wall of a building to the maximum degree.
Description
Technical field:
The present invention relates to construction engineering technical field, be specifically related to a kind of steel rope symmetry dismantle processes flow process of tower crane attachment device.
Background technology:
Perfect day by day along with the development of society and Building technology; High-storey business has become the favorite in market at present; The construction characteristic of this type building is generally to adopt the reinforced concrete shear wall structure technology, and main body construction speed is fast, and the material and the member single-piece weight of palpus vertical transport are big; The vertical transportation machinery full-load operation, this has just proposed challenge for the vertical transport in the work progress; Fixedly the hoisting capacity of attached tower crane, operational height, construction cost can both satisfy the construction needs; In order to accomplish economical rationality, guarantee construction speed, to guarantee safety; Fixedly attached tower crane becomes the first-selection of each unit in charge of construction; But; The demolishing process of tower crane but exists a lot of potential safety hazards, and the therefore perfect fixedly dismounting construction method of attached tower crane has just become a new problem, has very realistic meanings.
Fixedly attached tower crane often adopts the method for the auxiliary suspention dismounting of tower machine suspension hook when attachment device is removed, and the method existence swing when removing the half of adhering member of equilibrium arm direction is big, operating personal is subject to injure shortcomings such as destruction metope finished product.
Summary of the invention:
The steel rope symmetry dismantle processes flow process that the purpose of this invention is to provide a kind of tower crane attachment device, is prone to row, science, efficient at its safety, has guaranteed that to greatest extent civilized construction and environment avoid pollution.
In order to solve the existing problem of background technology; The present invention adopts following technological process: at first use load hook that the wall-attaching equipment of crane arm side is removed; Prick symmetrical wire rope device through the back of the body then the attached wall of equilibrium arm side is removed, the component of machine of arrangement inspection at last.
Dead work before removing mainly contains the situation of understanding the camp site, the cleaning obstacle; Carry out the safety method work of telling somebody what one's real intentions are to participating in dismounting tower machine personnel, and the tower machine of being dismantled is carried out complete machine inspection work; Check no potential safety hazard, be equipped with the wheel crane of a 25T under the normal at the construction field (site) condition, required instrument and fragment data when being ready to dismantle.
Fall standard knot and be the standard knot that falls more than the first road attached wall, the process of falling standard knot is opposite with the process that the body of the tower standard knot is installed.
For safety and protection building finished product, use following method for dismounting: the utilization suspension hook is removed the attached wall of crane arm one side earlier when removing attached wall, apart from equilibrium arm and cat head frame hinged place middle part, about 1.5 meters a fixed pulley is being installed again.Suspension hook drops down onto apart from ground about 1 meter, and steel rope and the master winch steel rope of φ 9 is locked, passes pulley and drops down onto lifting rope on the Ground lock, and the suspension hook that hoists hangs the attached wall of equilibrium arm one side and removes with the steel rope of φ 9.The ring beam framework that hangs equilibrium arm one side with the steel rope of φ 9 is again removed.Dismantle the at last steel rope of φ 9 is removed the ring beam framework of crane arm one side with the crane arm suspension hook.One attached wall removed and finished.Repeat above-mentioned steps the tower machine is reduced to height of foundation.
The present invention has following beneficial effect: its safety, be prone to row, science, efficient, guaranteed that to greatest extent civilized construction and environment avoid pollution.
The specific embodiment:
This specific embodiment adopts following technological process: at first, use load hook that the wall-attaching equipment of crane arm side is removed, prick symmetrical wire rope device through the back of the body then the attached wall of equilibrium arm side is removed, the component of machine of arrangement inspection at last.
Dead work before removing mainly contains the situation of understanding the camp site, the cleaning obstacle; Carry out the safety method work of telling somebody what one's real intentions are to participating in dismounting tower machine personnel, and the tower machine of being dismantled is carried out complete machine inspection work; Check no potential safety hazard, be equipped with the wheel crane of a 25T under the normal at the construction field (site) condition, required instrument and fragment data when being ready to dismantle.
Fall standard knot and be the standard knot that falls more than the first road attached wall, the process of falling standard knot is opposite with the process that the body of the tower standard knot is installed.
For safety and protection building finished product, use following method for dismounting: the utilization suspension hook is removed the attached wall of crane arm one side earlier when removing attached wall, apart from equilibrium arm and cat head frame hinged place middle part, about 1.5 meters a pulley is being installed again.Suspension hook drops down onto apart from ground about 1 meter, and steel rope and the master winch steel rope of φ 9 is locked, passes pulley and drops down onto lifting rope on the Ground lock, and the suspension hook that hoists hangs the attached wall of equilibrium arm one side and removes with the steel rope of φ 9.The ring beam framework that hangs equilibrium arm one side with the steel rope of φ 9 is again removed.Dismantle the at last steel rope of φ 9 is removed the ring beam framework of crane arm one side with the crane arm suspension hook.One attached wall removed and finished.Repeat above-mentioned steps the tower machine is reduced to height of foundation.
The technological principle of this specific embodiment is: at first with after the tower machine adjustment balance; Remove the ring beam framework and the strut of the half of attachment device of crane arm direction with the suspention of tower machine suspension hook in advance; When the ring beam framework of the half of attachment device of removing the crane arm direction; The ring beam framework of wanting earlier the equilibrium arm direction to be adhered to ties with three boomers and standard knot, comes off when preventing the removal flange bolt.The back of the body is pricked steel rope on the master winch rope then, and ring beam framework and strut that the mode that makes the back of the body prick steel rope and the synchronized operation of master winch rope is adhered to the equilibrium arm direction are removed.
This specific embodiment safety, be prone to row, science, efficient, guaranteed that to greatest extent civilized construction and environment avoid pollution.
