Description
Technical Field
The invention relates to a quick-mounting and quick-dismounting formwork system of a building ribbed structure and a construction process thereof, belonging to the technical field of building structures and construction processes thereof.
Background
The plastic shuttering as one new type of formwork system is widely used in building engineering in recent years, and the ribbed floor system formed with the plastic shuttering has excellent economic benefit, replacing traditional ribbed beam structure system gradually.
At present, the traditional formwork construction mode is as follows: the method comprises the steps of building a full scaffold, paving square timbers on the scaffold, paving bamboo plywood or wood plywood on the square timbers, placing a formwork on the surfaces of the bamboo plywood or the wood plank at fixed points, fixing the periphery of the formwork on the bamboo plywood or the wood plywood by constructors, laying reinforcing steel bars in the peripheral space of the formwork, pouring concrete, and disassembling the formwork after the concrete meets the standard requirements (generally over half a month). The traditional formwork construction mode has the following main disadvantages:
1. the bottom adopts traditional full hall scaffold frame as the support, causes that construction space is narrow and small, can't satisfy personnel's construction and walk about and material transport to the support time will last whole work progress and can not wholly demolish until reaching the drawing of patterns standard after, and the construction period is long, and steel pipe and connecting piece are very many, and the safety risk is big.
2. The mould shell is fixed on the plywood or the bamboo plywood, and the use of the plywood or the bamboo plywood is not environment-friendly on one hand and the waste of forest resources is serious; on the other hand, the wood plywood or the bamboo plywood has the advantages of less cycle times, low utilization rate, abandonment after demolding and dismantling, no repeated cyclic utilization, cost waste and more garbage generated on the construction site.
3. In order to prevent the horizontal displacement of the formwork under the action of the lateral pressure of concrete in the construction process, the formwork is fixed after wood ridges are paved and wood plywood or bamboo plywood is paved before pouring, so that the construction operation of the formwork is complicated, the formwork is detached after pouring forming is complex, the labor intensity is high, the construction efficiency is low, and the construction period is long.
4. The bearing capacity of the plywood or the bamboo plywood is insufficient, the deformation phenomena such as mold burst and mold expansion are frequently caused due to the limitation of the characteristics of the wood, the forming effect is poor, and the construction quality is poor.
5. In the whole construction process, the formwork, the matched plywood or the bamboo plywood can be completely dismantled after the concrete is completely cured, so that the using amount of the formwork and wood needed by a construction site is very large.
6. In order to improve the strength of the formwork and prevent the formwork from deforming under pressure after concrete is poured, the conventional method needs to arrange a main keel and a secondary keel on the formwork.
7. Concrete formed by a traditional formwork construction system has a rough surface, a surface layer cannot be directly coated after demoulding, and manual mortar trowelling treatment is needed.
