Problems solved by technology
In this patent document, reinforcing ribs are set in the hollow formwork. Compared with the solid building formwork, it can effectively reduce the amount of raw materials, reduce the weight of the formwork and facilitate production while ensuring the mechanical strength of the hollow building formwork. However, for metal templates, due to the nature of the material and the poor fluidity of its melt, it is technically difficult to directly produce such high-density ribbed templates through the extrusion process, and the density is too low. The role of the board will not be apparent
In addition, this extruded structure, the template produced is full of reinforcing ribs, which is not the best structure for the template made of metal materials. On the one hand, it is heavy and inconvenient to use, and the material wasteful
On the other hand, the structure with ribs all over is not ideal for the change of formwork force, especially for improving the bending strength

Embodiment Construction
[0030] Such as Figure 1-3 As shown, a hollow composite building formwork of this embodiment includes a formwork body, a first side panel 1, a second side panel 2, and the first side panel 1 and the second side panel 2 A number of first ribs 3 that act as connections and extend along the first direction;
[0031] Between the first side plate 1 and the second side plate 2 of the formwork body, and between each of the first ribs 3, it is fixed along a second direction perpendicular to the first direction Several rib units 4 are installed, the width of the rib units 4 in the first direction is smaller than the length in the second direction, and the rib units 4 are arranged at intervals along the first direction.
[0032] The above-mentioned solution is the core solution of the present invention. By arranging several reinforcing rib units 4 at intervals along the first direction in the formwork body, compared with the prior art, not only can reduce the use of materials for makin...

A hollow combined building formwork, comprising a formwork body, having a first side panel, a second side panel, and a connection between the first side panel and the second side panel and extending along a first direction a number of first ribs; between the first side plate and the second side plate of the formwork body, and between each of the first ribs, along the direction perpendicular to the first direction Several rib units are fixedly installed in the second direction, the width of the rib units in the first direction is smaller than the length in the second direction, and the rib units are arranged at intervals along the first direction. The processing technology of the hollow composite building formwork of the present invention is simple, and on the premise of enhancing the strength of the hollow formwork, raw materials can be further saved, so that the entire hollow composite building formwork is lighter in weight.
Description
technical field [0001] The invention relates to the construction field, in particular to a hollow composite building formwork for strengthening the strength of the hollow building formwork. Background technique [0002] The building formwork used in the construction of cast-in-place concrete structures is a temporary model structure to ensure that the concrete structure is poured and formed according to the design requirements. The temporary model structure is usually spliced by a plurality of building templates according to a certain splicing method. In recent years, with the development of technology, hollow building templates have emerged as the times require. The hollow building formwork in the prior art is usually formed by extrusion, and the extruded hollow building formwork is weak in the non-extruded direction, so the hollow building formwork is usually reinforced by a rib structure. [0003] For example, in the hollow plastic building formwork disclosed in Chine...
