Embodiment 1
[0018] Example 1, such as Figure 1 to Figure 3 As shown, a complex space multi-surface fair-faced concrete structure wood formwork manufacturing method includes the following steps.
[0019] Step A): Select several cross-sections at different heights according to the three-dimensional model diagram of the complex space multi-surface structure, and the vertical distance between adjacent cross-sections is controlled between 1 / 20 and 1 / 50 of the total height, The vertical separation distance should not be less than 20cm. The specific vertical spacing distance of adjacent cross-sections and the total number of cross-sections need to be adjusted according to the actual size of the fair-faced concrete structure with multi-curved surfaces in complex spaces during actual fabrication. Generally speaking, the vertical separation distance between adjacent cross-sections is equal and the separation distance is 1 / 40 of the total height. This selection is suitable for models with a heigh...

The invention relates to a wooden formwork manufacturing method for a concrete structure, in particular to a wooden formwork manufacturing method for a complex space multi-cambered facing bare concrete structure. A wooden formwork for the complex space multi-cambered facing bare concrete structure is manufactured through the six steps of measurement, cross section control frame manufacturing, vertical camber control keel frame manufacturing, cross section control frame splicing, wooden strip splicing, facing formwork tight sticking and fixing and piecing treatment. Compare with the prior art, the method is mainly applied to construction of a complex space multi-cambered facing bare concrete structure model, completely adopts wood splicing and installing, and has the advantages that space positioning is simplified, manufacturing cost is low, the formwork turnover rate is high, construction cost is obviously reduced, and material waste is reduced; and the problems that previous complex space multi-cambered facing bare concretes are difficult to make, high in cost, and slow in manufacturing speed are solved.
Description
technical field [0001] The invention relates to a method for manufacturing a concrete structure wooden formwork, in particular to a method for manufacturing a clear-faced concrete structure wooden formwork with complex spaces and multi-curved surfaces. Background technique [0002] With the rapid development of the modern national economy and the construction industry, people have higher and higher requirements for the aesthetic feeling of buildings. There are more and more architectural designs with novel shapes, complex shapes, and more satisfying modern people's aesthetic standards, including a large number of complex-designed fair-faced concrete structures with multi-curved surfaces. Multi-curved concrete structures usually need to rely on a large amount of spatial positioning information for positioning. If on-site spatial positioning is used, great requirements are placed on the measurement work of the construction unit, and it is difficult to ensure the accuracy of po...
