Description

Cylindrical reticulated shell bearing horizontal sliding structural entity construction method for forming
Technical field
The present invention relates to the cylindrical reticulated shell job practices, is a kind of cylindrical reticulated shell bearing horizontal sliding structural entity construction method for forming.
Background technology
The job practices commonly used of cylindrical reticulated shell has: (1) high altitude bulk method; (2) high-altitude sliding method; (3) the itemize piecemeal is installed method; (4) whole hanging method; (5) whole lift method; (6) integral jacking method.These job practicess respectively have characteristics, but have following problem to some extent: temporary support scaffold consumption is big, long construction period; The construction cost height; Amount of high-altitude operation is big, and working security is poor; The cumulative errors problem of construction assembly unit is outstanding; Upper air installing contraposition splicing difficulty; The potential safety hazard of interim bearing bracket is outstanding; The stable problem of lift-up device is outstanding or the like.
Summary of the invention
The purpose of this invention is to provide a kind of cylindrical reticulated shell bearing horizontal sliding structural entity construction method for forming, be to divide domes two sections to carry out the ground assembling, in assembling and construction stage, two sections connections and two bearings of bar structure are made rotary hinged joint, thereby and one of them bearing can be free to slide in the construction forming stage structure finally is shaped.
In order to achieve the above object, the technical solution used in the present invention is as follows: cylindrical reticulated shell is divided into two sections assemblings of dividing into groups, an end points that is divided into the cylindrical reticulated shell before two sections is a fixed-hinged support, two sections joints are that hinged joint is shelved on the falsework, another end points that is divided into the cylindrical reticulated shell before two sections is placed in the slideway for the slip hinged-support, the slip hinged-support is under the horizontal external effect during construction, make horizontal pushing tow or do the horizontally tracting motion continuously to the segmentation of fixed-hinged support direction until the design attitude that arrives the slip hinged-support, then slip hinged-support and basis are connected and fixed, when hinged joint also arrives its design elevation, again horizon bar is connected, hinged joint is fixed.
The present invention compares the beneficial effect that has with background technology:
1) installation accuracy height, construction quality is good
Because at the structure assembling stage is to carry out in the position near ground, the negative effect of having avoided work high above the ground to bring to construction quality is so installation (welding, assembling) precision and quality can access effective inspection and assurance.The latticed shell structure in construction forming stage is similar to a three hinged arch structure, and one of them bearing moves horizontally on ground under jacking force or tractive force effect until arriving its design attitude, and the control of this support position and motion is very convenient and is easy to.Shaping stage arch with encircle between, between the rod member between arch and the bearing, on the arch the change of relative position can not take place all, so also just do not have the installation cumulative errors problem of many conventional construction methods.
2) construction safety
The very close ground of the structure of assembling stage, the potential safety hazard of having avoided constructor's work high above the ground to bring.Structure is a mechanism with single degree of freedom in the monolithic molding construction stage, the direction of this degree of freedom is that horizontal direction and movement position are on ground, the pushing tow of this bearing or traction available hydraulic jack are finished, so be very convenient and safe and reliable the control work of this one dimension degree of freedom.Simultaneously, owing to do not need, so the yet potential safety hazard that does not just exist the cripple stable problem to be brought with the interim load supporting scaffold that resembles the high altitude integrated lift method.Therefore, this construction technology all is good in the safety of structural entity shaping stage still at assembling stage.
3) short construction period
Because the work plane of assembling stage reduces the consumption of scaffold significantly, thereby saved the assembling and the take-down time of scaffold near ground, Zhuan Pei work plane also can fully spread out simultaneously, and erection work and quality examination operating efficiency are improved greatly.Structure allows the B bearing put in place in the ground level slippage in unique work of monolithic molding construction stage exactly, and this work generally can be finished in one day.Therefore, the duration of this construction technology will be less than the required time of traditional job practices greatly.
4) construction cost is low
The minimizing significantly of scaffold consumption will reduce interim materials of construction and mounting or dismounting expense greatly, and the monolithic molding construction stage can be adopted mini-plants such as hydraulic jack, need not large-scale hoisting machinery, also have the factors such as shortening of construction period simultaneously.Therefore, the construction cost of this construction technology will be lower than the operating expenses of traditional job practices.
