Convenient mounting and dismounting type combined prefabricated template suitable for building floor descending plate

Abstract

The invention relates to a convenient mounting and dismounting type combined prefabricated template suitable for a building floor descending plate. A main body comprises a template frame formed by mutually connecting the end parts of a combined transverse steel frame plate and a vertical steel frame plate which are prefabricated by square steel plates, and limiting plug pins, a twisted steel bar serves as the limiting plug pins, interconnecting plates with limiting plug pin holes A are fixedly arranged at the two ends of the transverse steel frame plate, limiting plug pin holes B are formed inthe plate faces of the two near ends of the vertical steel frame plate, the limiting plug pins are correspondingly inserted into the limiting plug pin holes A and the limiting plug pin holes B to form a stable steel template, deformation is avoided, limiting is reliable, grout leakage can be avoided, after curing and forming, bonding and interconnection are avoided, corners of concrete are not damaged during template dismounting, the forming precision can be ensured, repairing and chiseling work in the later template dismounting period is avoided, the dismounted template can be recycled, andthe defects that in the prior art, a template is poor in stability and forming effect, the quality is difficult to guarantee, the size deviation is large, the construction cost is high and the like are overcome, and high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of infrastructure auxiliary facilities, in particular to a conveniently installed and disassembled combined prefabricated formwork suitable for lowering slabs of building floors. Background technique [0002] In the concrete structure construction of general civil buildings, it is often encountered in the sub-item construction of lowering slabs involving water parts such as bathrooms, kitchens, and balconies. Usually, it is required that there is a gap of about 5cm between the slab surfaces of these parts and the slab surfaces of adjacent rooms. The drop is realized by the traditional customary method of dismantling and assembling and fixing the wooden square formwork with iron wires. Its disadvantages are: in the process of pouring concrete, due to the light texture of the wooden formwork, it will float up and the reliability of the limit is poor, making it difficult to control the elevation; In the proces...

AI Technical Summary

Problems solved by technology

Its disadvantages are: in the process of pouring concrete, due to the light texture of the wooden formwork, it will float up and the reliability of the limit is poor, making it difficult to control the elevation; In the process of contact with concrete for a long time, the texture will change, which will reduce the bending strength and rigidity, and the use of iron wires to fix it will cause uneven force on the wooden formwork, which will affect the overall stability of the hanging formwork and easily lead to Grout leakage occurs due to uneven joints of the hanging formwork; and due to the penetration of slurry water, the surface of the wooden formwork and the concrete are tightly bonded, it is difficult to peel off the formwork, and it is easy to cause pockmarks, holes, and defects in the concrete after the formwork is removed. Quality problems such as edge drop and large size deviation

Therefore, the traditional construction mode using wooden hanging formwork is generally not scientific and reasonable, the quality is difficult to control, the forming effect is poor, the workload of repairing and chiseling in the later stage is also large, the investment of manpower, material resources and financial resources is large, and the construction cost is high. Moreover, many shortcomings such as poor molding effect are not ideal from the perspective of economy and practicability.
