Description

A new type of steel-wood box inner mold

Technical Field

The utility model belongs to the technical field of inner molds for hollow floor slabs, and specifically relates to a novel steel-wood box inner mold.

Background Art

With the rise of real estate, all kinds of buildings have sprung up, and most traditional building structures adopt frame and plate solutions, which greatly limit the height of the building and reduce its use function. Nowadays, steel mesh box mesh box inner mold technology is also used to increase the use area, save the amount of concrete, reduce the weight of the building structure, and reduce production costs. However, the existing steel mesh box mesh box inner mold is easily deformed by external forces when no concrete is poured, which reduces its supporting strength. At the same time, because it is made of metal, the cost is relatively high.

Utility model patent CN202021780127.7 discloses a new type of steel-wood box inner mold, including a rectangular box, a support frame assembly is fixedly arranged in the rectangular box, and the support frame assembly is fixedly connected to the four side panels of the rectangular box respectively, and each side panel of the support frame assembly and the two adjacent side panels of the rectangular box form a stable triangular structure. It provides a more stable, firm and pressure-resistant structure. The side panels and support panels are made of building wood boards, which turns discarded building templates into treasures, reduces material costs and saves energy and is environmentally friendly. However, the overall strength of this box-type inner mold is not high. Although the triangular structure is more stable, the four walls of the box-type inner mold have a high strength in bearing cement, but the lack of upper and lower reinforcement makes its load-bearing capacity poor, resulting in a reduction in the overall strength of the box-type inner mold. Therefore, a new type of box-type inner mold is needed to meet market demand.
