Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering, and specifically relates to a continuous light floor. BACKGROUND

[0002] As a new building method, prefabricated farmhouses have indeed gained more and more attention and development in rural areas in recent years. The core of this building mode is to transfer a large number of on-site construction operations in traditional building methods to factory environment for completion, that is, to produce the components and members of the building in a factory, and then transport them to the construction site for assembly and installation. This method not only improves the construction efficiency and reduces the impact on the environment, but also ensures the quality consistency of the building.

[0003] However, in the actual construction process, the existing technical system is not without challenges. In particular, in prefabricated steel structure farmhouses, the floor structure is mostly made of steel bar truss floor support plate or laminated board, and the construction process often involves a large amount of on-site wet work, such as pouring of ordinary concrete. Although this practice inherits some characteristics of traditional buildings, it also introduces a series of problems.

[0004] First of all, the existence of on-site wet work means that even if the prefabricated components have been in place, a certain amount of manual operation cannot be avoided. This not only increases the time cost of construction, but also makes the entire project progress affected by external factors such as weather. In addition, manual operation may also bring uncertainty in quality control, because different workers may have different technical levels, which may affect the quality of the final building.

[0005] Secondly, due to the need for on-site concrete pouring, the construction speed is relatively slow. Although one of the important advantages of prefabricated buildings is to speed up the construction progress, when it comes to concrete pouring, this advantage is greatly discounted. From the template erection, concrete pouring to the final curing, each step needs time, especially in winter construction, in order to ensure that the concrete reaches sufficient strength, the curing period may be longer, further prolonging the construction period.

[0006] Furthermore, the problem of large structural self-weight is a significant challenge faced by prefabricated farmhouses under the existing technology. The use of traditional concrete floors increases the overall weight of the building, which puts higher requirements on the foundation design. In order to support the heavier upper structure, the foundation part must be more solid, which increases the cost of foundation construction.

[0007] Finally, the problem of excessive material consumption cannot be ignored. The production of traditional concrete floors requires a large amount of cement, sand and other raw materials, the mining and processing of these resources not only consumes a large amount of energy, but also causes negative impact on the environment, therefore, excessive material consumption is contrary to the concept of environmental protection, which is not conducive to the long-term development of prefabricated farmhouses.
