Embodiment 1

[0044] Embodiment one sees Figure 5 As shown, the framed plastic formwork used for multiple turnovers includes a panel 2, the panel 2 is embedded in the upper end of the frame 3, the upper surface of the panel 2 and the outer side of the frame 3 are tightly covered with a plastic skin 1, and the panel 2 The upper surface of the upper surface is flush with the upper end of the frame 3, the lower port of the epidermis 1 is flush with the lower end of the frame 3, and the side of the epidermis 1 matches the shape of the side of the frame 3.

[0045] see figure 1 As shown, the skin 1 has five surfaces, namely the upper surface and four sides, which are formed by extrusion injection molding process, and its length, width and height dimensions match the length, width and height dimensions of the frame. , tightly covering the outer surface of the outer frame of the frame;

[0046] see figure 2 As shown, the shape of the panel is a thin cuboid structure, and it is a lightweight a...

Embodiment 2

[0050] Embodiment two see Figure 7 , Figure 8 , Figure 9As shown, the difference from the first embodiment is that the four sides of the frame 3 are hollow profiles.

Embodiment 3

[0051] Embodiment three see Figure 10 , Figure 11 , Figure 12 As shown, the difference from the first embodiment is that the boss 7 of the frame 3 is located on the upper part of the frame, and the thickness of the frame in this embodiment is smaller than that of the previous two embodiments.

[0052] A construction method for applying the described plastic formwork with a frame for repeated turnover, the specific steps are as follows:

[0053] Step 1, preparing the skin 1, the panel 2, and the frame 3, and connecting the reinforcing rib 4 to the frame 3.

[0054] Step 2, embed the panel 2 into the upper position of the frame 3 .

[0055] Step 3, cover the skin 1 on the outside of the panel 2 and the frame 3 from top to bottom.

[0056] Step 4, connect and fix the side surface of the skin 1 with the frame 3 to complete the construction of the plastic formwork.

[0057] Step five, the formed plastic formwork can be transported to the construction site as a concrete pour...

Abstract

A framed plastic formwork used for multiple turnovers and its construction method. The formwork includes a panel, the panel is embedded in the upper end of the frame, and the upper end of the outer side of the frame has a horizontally convex flange. Tightly covered with a plastic skin, the upper surface of the panel is flush with the upper end of the frame, the lower port of the skin is flush with the lower end of the frame, the side of the skin matches the shape of the side of the frame, and the frame is connected with reinforcing ribs. The present invention is an integrated product composed of skins, panels, and frames, and the number of times of use is significantly increased, which is conducive to improving resource utilization, effectively solving the waste of resources in formwork engineering in the construction industry, and reducing construction environmental costs, economic costs, and labor costs; the present invention It can replace bamboo and wood plywood, wooden squares, secondary beams and other products, and it can be used in conjunction with an independent support system to simplify the construction process of concrete engineering, improve construction efficiency, and improve construction quality. It can be widely used in concrete pouring formwork system.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a formwork for building and a construction method thereof. Background technique [0002] After years of development, bamboo plywood products still occupy a dominant position in the field of construction in my country. The application of these products has produced a huge amount of waste of forest resources and green resources, which has caused serious adverse effects on environmental protection and sustainable development of society. [0003] Among the alternative products of bamboo and wood plywood, plastic formwork is considered to be a product with great development potential, but this product still has obvious shortcomings: the corners are easily damaged, which greatly reduces the number of product cycles. However, in the application process of bamboo-wood plywood, the main construction method is still scattered, branched and scattered. This construction method is cumber...
