Description
Technical Field
The utility model belongs to the technical field of building engineering, concretely relates to prefabricated coincide floor forming die of concatenation formula.
Background
The assembly type technology is a novel green and environment-friendly construction mode, is favorable for realizing energy conservation and emission reduction, and is a future development trend of the building industry. In recent years, the emphasis and the vigorous development of fabricated buildings have been raised to the national level. In "a few opinions of the common central State Council on further strengthening the urban planning construction management work" coming out in 2016, it was pointed out that the time of about 10 years is strived to make the assembled building account for 30% of the new building. The Likeqiang general theory further emphasizes in government work reports of the two parties, so that the assembly type building is vigorously developed, the standardized construction is accelerated, and the technical level and the engineering quality of the building are improved. Other provinces and cities develop assembly building implementation opinions on vigorous development. At present, more than 500 assembly type component manufacturers exist in China. The new house areas of 20.1 hundred million square meters, 19.5 hundred million square meters and 19.1 hundred million square meters in 2019-2021, the occupation ratio of the fabricated building is 17.5%, 20.5% and 23%, and the new house areas of the corresponding fabricated building are 3.5 hundred million square meters, 4.0 hundred million square meters and 4.4 hundred million square meters respectively. The prefabricated composite floor slab is a main component of the fabricated building, has the advantages of good structural integrity, great reduction of cast-in-place templates, guaranteed quality, convenience in construction and the like, and is a preferred component in the fabricated building.
In the production process of the prefabricated composite floor slab, the floor slab part is split into a plurality of composite floor slabs with different sizes according to the design drawing of a building project, and then a mold is manufactured according to the size of the composite floor slabs. The traditional die is made of steel and cast aluminum, and needs cutting, welding, hole opening and other processes, so that the production is time-consuming, labor-consuming, resource-wasting and environmentally-friendly. In the process of producing the prefabricated composite floor slab, the characteristics are as follows: 1. the weight per meter is as high as 10kg-15kg, so that workers waste time and labor in the assembling process, and the efficiency is extremely low; 2. the cost of the die is high, and is as high as 150 yuan to 180 yuan per meter; 3. the vertical plate of the die is provided with a plurality of rib penetrating holes or rib penetrating grooves, so that the die is easy to bend and deform, the die with light deformation in the production process is repaired (manpower is consumed, the working time is delayed), the die with serious deformation is scrapped, the required die has to be manufactured again, the assembly difficulty is increased, and the production cycle and the component precision are influenced; 4. because the coincide floor size, play muscle position, the reinforcing bar size of different projects are different, and every project all needs reprocess the mould that meets the requirements according to concrete structure and size, leads to can not circulate the sharing between the mould of different projects.
To sum up, the cost of using traditional mould production prefabricated coincide floor still will be higher than cast-in-place floor cost, and then has hindered the popularization process of prefabricated building.
The prefabricated superimposed sheet mould technical patent of current nonmetal concatenation: the technical solution disclosed in the patent application document is represented by: 1. too many play muscle groove has been seted up on the vertical board of mould, for preventing that the mould warp, design length is shorter, and the assembly part is more, increases the man-hour of workman's assembly, and production efficiency is not higher than traditional mould. 2. Because go out muscle groove and piece more, lead to leaking the thick liquid phenomenon seriously, influence the component quality, increase the degree of difficulty of subsequent handling simultaneously. 3. The injection molding pre-embedding process is adopted, and the mold production cost is high due to the fact that parts are more and the mold opening cost is high and is 2-4 times of that of a traditional steel mold.
