This application can make the luffer boards structure of wafting once only pour the shaping along with the major structure, avoids the secondary to pour, has solved the problem that can't fix on the PC board and has hung the mould support simultaneously, has the effect of making things convenient for site operation and reduction of erection time.
Description
Technical Field
The invention belongs to the technical field of constructional engineering, and particularly relates to a construction method of a one-time pouring bay window formwork erecting structure.
Background
In the current high-rise building design, the building facade is often more complicated in modeling, and the outer wall node is many, and especially modern apartment formula building has often designed a large amount of windows that waft, and to the window board that wafts about designing in the construction usually divide equally to accomplish for twice pouring. Because the concrete pouring amount of the secondary pouring floating window plate is relatively small, the situation that the small-volume concrete is not supplied timely or is supplied intermittently can often occur in the actual concrete supply process, and great influence is caused on the construction progress and the integral coordination of resources. Meanwhile, in the deepening design of the individual steel climbing frame, the fixed support can be arranged on the secondary pouring floating window plate vertical wall, and under the condition, the waiting time before the climbing frame is lifted can be effectively shortened only by finishing the secondary pouring of the floating window plate as soon as possible. The technology that the bay window board can not be poured once causes the influence of to a great extent to time limit for a project and construction organization, can indirectly cause construction cost to increase. Therefore, the problem to be solved is to realize the one-time pouring of the floating window plate.
Disclosure of Invention
The invention aims to provide a construction method of a one-time pouring bay window formwork supporting structure, which can realize one-time pouring of an upper bay window structural plate and a lower bay window structural plate, avoid secondary forming, improve the overall rigidity and stability of a vertical hanging die, enable the whole formwork supporting system to work cooperatively, jointly bear the external force effects of the self weight, the lateral pressure, the construction load and the like of concrete, and reduce the deformation of a building formwork in the concrete pouring process.
In order to achieve the purpose, the invention adopts the following technical scheme:
a construction method of a one-time pouring bay window formwork erecting structure comprises the following steps:
step 1, erecting a lower support frame, installing a wood template I with a horizontal downward floating window plate on the lower support frame, installing a vertical wood template I on the outer side of the wood template I, installing battens on the outer side of the vertical wood template I, and drawing and fixing the battens with the wood template I through iron wires; a vertical steel frame wood formwork I is mounted at the end of the inner side of the wood formwork I;
step 4, a hole is formed in the vertical wood formwork II on the outer side of the boundary beam, which is opposite to the end part of the reinforcing device on the integrated hanging formwork support on the PC board, a harness cord screw is screwed into a plastic nut at the end part of the reinforcing device through the hole to be connected into a whole, and the lengthened harness cord screw penetrates through the double-batten main keel and the vertical wood formwork II to be connected and fixed with the exposed truss steel bars on the PC board;
and 7, checking and accepting, and pouring concrete at one time.
The invention has the technical effects that:
1. the common mould hanging bracket and the peripheral reinforcing device are utilized to make the upper and lower floating window plates can be poured at one time along with the main body structure. Utilize the integral type to hang the mould support, through being connected fixedly with the exposed truss reinforcing bar spot welding of PC board, solved the fixed problem of hanging the mould support of nail that can't use on the PC board, improve stability. And marking a white paint mark on the reinforcing device to ensure the forming width of the concrete boundary beam. The plastic bolt caps of the peripheral reinforcing devices are used for propping the vertical templates on the inner side and the outer side, and the lengthened harness cord screws are used for pulling the inner support of the templates outwards, so that the relative distance between the vertical templates on the inner side and the outer side is strictly controlled, and the position accuracy of the vertical templates is ensured.
2. By adopting the technical scheme, the integral rigidity and stability of the vertical suspended formwork can be improved, the formwork and the keel work together to bear the external force effects of the self weight of the concrete, the lateral pressure, the construction load and the like, and the deformation of the building formwork in the concrete pouring process is reduced.
3. Through adopting above-mentioned technical scheme, the problem of the once only pouring of wafing window board concrete has fundamentally been solved, especially also be applicable to PC coincide floor design equally, the adaptability is stronger, and construction cost is low, and it is convenient, swift, firm to consolidate, can guarantee concrete shaping quality, be fit for the engineering project large tracts of land popularization that has the wafing window, still be applicable to structure lifter plate, go up anti-roof beam, concrete turn-ups molding, the anti-bank of water room concrete is once only pour the position such as along with a structure simultaneously, has very good popularization prospect.
