Embodiment 3

[0062] Embodiment 3: roughly the same as Embodiment 1, the difference is that the through hole is a cross-shaped through hole with a width of 8 mm, the distance between two adjacent plastic columns 2 is 100 mm, and the thickness of the plastic composite layer 3 is 6 mm. The thickness is 30mm, the substrate 1 is made of sawdust board, and the plastic slurry is made of micro-foamed PVC plastic. The formulation of the plastic slurry is shown in Table 3. In the manufacturing method, the temperature of the plastic slurry in step (1) is raised to 120-160°C. The maximum temperature of PVC plastic should not exceed 160°C for a long time, otherwise it will burn. Step (4) Cool in the water tank for 2 minutes. The service life of this embodiment can reach 45 times.

Abstract

The invention discloses a novel compound building template. The novel compound building template comprises a base plate, plastic connecting columns and plastic compound layers, wherein through holes for array processing are fully distributed on the base plate; the plastic connecting columns penetrate into the through holes of the base plate; the plastic compound layers are respectively adhered to the upper and the lower surfaces of the base plate tightly, and connected with the plastic connecting columns to form integral structures. The plastic compound layers on the upper and the lower surfaces of the building template are used for pressing the base plate to a middle layer by the plastic connecting columns; the plurality of the plastic connecting columns which are integrated with the plastic compound layers can be used for generating strong riveting force as rivets to fasten up the base plate between plastic surface layers to form the integral firm structure of the building template; the plastic layers of the surface layers are easy to de-mould, and the base plate can be used for providing big bearing capacity. The novel compound building template is difficult to corrupt, unlikely to deform, light in weight, reliable in strength, good in processing performance, 10 times or more than the common bamboo-wood building template in service life and extremely good in de-molding performance, thereby greatly improving the construction efficiency, saving the materials and the construction cost, ensuring the surface of a concrete component to be flat and smooth, and achieving high cost performance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a building formwork. Background technique [0002] The building formwork is a temporary support structure, which ensures that the concrete structural members are formed according to the specified position and geometric size, maintains its correct shape, and bears the self-weight of the building formwork and the external load acting on it, and assembles it in advance according to the design requirements. Forming formwork for beams, columns, walls, and floors can be assembled in place as a whole, or in bulk. The building formwork generally uses bamboo, wooden plywood, steel plate or aluminum alloy plate as the formwork. When the traditional formwork is used, the surface is easy to stick to the cement, and the cement surface is easy to be uneven when demoulding, which cannot guarantee the accuracy and beauty of the concrete structure. Bamboo and wood materials are perishable, and...
