Problems solved by technology

The processing technology of special-shaped ribs is complicated. Due to the processing error and structural limitations, there is a joint line between the panel part and the rib part. The forming effect is not as good as that of the one-time forming surface layer. It depends on the requirements of the construction site for the forming surface.
[0006] Plastic templates are mainly divided into injection molding and compression molding. The disadvantage is that the product specifications are fixed, and new specifications require new molds, resulting in high development costs.
[0007] Disadvantages of metal structural panels: heavy weight, difficult maintenance, high cost, difficult processing
[0008] Disadvantages of plastic structural panels: product specifications are fixed, and different specifications need to be separately designed and manufactured

Embodiment

[0082] Example: such as Figure 7 As shown, the upper and lower ends of the composite hollow structural panel 100 shown are respectively sealed with head plates 200 . The head plate is used to seal the upper and lower ends to protect the upper and lower ends, prevent the product from being broken when it falls and prevent slurry leakage, and at the same time provide a connection structure for the upper and lower ends. Two symmetrical blocks 2001 protrude from the lower end of the head plate 200, and the grooves formed by each of the side ribs 132 and the middle rib 133 match the blocks 2001. The two blocks 2001 directly have a receiving groove 2002, and the middle The reinforcing rib 133 is embedded in the receiving groove 2002, and the clamping block 2001 is embedded in the groove so as to install the head plate on the end of the composite hollow structural plate 100, and the head plate 200 and the composite hollow structural plate The left and right side surfaces and the re...

Abstract

The invention provides a composite hollow grid-like structural plate and a manufacturing method. Continuous fiber is adopted to reinforce a first reinforcing layer; the first reinforcing layer is embedded in a template through the pultrusion process and melts to form an integrity with the template, so that the product performance is improved. Compared with the prior art, the composite hollow grid-like structural plate has higher strength on the condition of the same cross section area. On the condition of ensuring consistent strength, the cross section area of the composite hollow grid-like structural plate is smaller, so that the weight of the composite hollow grid-like structural plate is reduced. Two side ribs provide main support force and simulate a dorsal rib to be used, so that thenumber of reinforcing members during construction is reduced. According to the manufacturing method, the composite production process is adopted to ensure the entire continuity of continuous fiber, and in the prior art, the continuous fiber is sheared through occlusion of screw rods. With adoption of the manufacturing method, the structure adjustment is simple, the width can be customized througha die, and arbitrary cutting in the length direction can be carried out.

Description

technical field [0001] The invention relates to the field of building templates, in particular to a composite hollow structural board and a manufacturing method thereof. Background technique [0002] The main advantages of structural building templates are as follows: 1. Modularization, standardized production, and easy connection. The construction and installation are carried out according to the drawings, and it is easy for workers to get started. 2. Because of its structural design, it can effectively reduce the number of reinforcements and parallel pulls, reduce the cost of use and improve construction efficiency. 3. The turnover times are high and the molding effect is excellent. The existing structural formwork on the market is mainly divided into: steel formwork, aluminum formwork, plastic steel formwork, and plastic formwork. [0003] Steel formwork is heavy and its specifications are limited. Steel formwork exceeding 1 meter in size cannot be carried by a single ...
