Description

Technical Field

[0001] The utility model relates to the technical field of building templates, in particular to a double-layer cavity template and a template device. Background Art

[0002] At the construction site, before pouring reinforced concrete, it is necessary to build a building formwork first, splice multiple building formworks to form the required structural form, and use pillars to support the building formwork to avoid deformation or collapse when pouring concrete. When the concrete reaches the final setting age, the pillars and building formwork are removed. Existing building formworks are mainly divided into three categories. The first category is wooden formworks. The advantage of wooden formworks is that they can be quickly cut according to the needs of on-site use. The disadvantage is that the concrete pouring and molding effect is poor and depends on the technical level of the workers. The wooden formwork has a large loss and a short service life. The second category is aluminum alloy formworks. The advantage of aluminum alloy formworks is that the structural strength is large. The disadvantage is that the cost is high and it cannot be quickly cut according to the needs of on-site use. The third category is plastic formworks. The material cost of plastic formworks is between that of wooden formworks and metal formworks, and plastics are easy to be injection molded in one piece to obtain the required shape. Therefore, the application of plastic formworks is becoming more and more extensive.

[0003] In order to improve the structural strength of the plastic formwork, the plastic formwork is usually divided into two parts, one part is the supporting body in contact with the concrete, and the other part is the reinforcing structure for improving the strength. The reinforcing structure is used to support the supporting body. At the same time, in order to reduce material costs, the plastic film is usually hollowed out. For example, a building formwork assembly with application publication number CN108442686A can improve the structural strength of the formwork body by using the reinforcing structure. The reinforcing structure includes a supporting plate and an arched plate. The supporting plate, the arched plate and the formwork body together form a middle hole. However, this can easily cause the cavity wall of the formwork to be too thin and weak in impact resistance. When it hits a sharp object or is impacted by a concentrated force during construction, it is easy to be damaged. Utility Model Content
