Problems solved by technology

However, after this formwork component is applied to the cast-in-place concrete hollow floor, the formed floor will inevitably be equipped with components such as various lines, and often needs to drill holes on the newly repaired floor, and it is difficult to install. Repair is very troublesome

Embodiment Construction

[0115] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0116] As shown in the accompanying drawings, the present invention comprises an upper box plate 1, a lower box plate 2, a filling mold 3 clamped between the upper box plate 1 and the lower box plate 2, and is characterized in that the filling mold 3 is an annular frame mold, and the annular frame The mold is formed by connecting at least two templates 4 . In each accompanying drawing, 1 is an upper box board, 2 is a lower box board, 3 is a filling mold, and 4 is a template. In the following accompanying drawings, those with the same numbering have the same description. As shown in Figure 1, the concrete sandwich member includes an upper box 1, a lower box 2, a filling mold 3 sandwiched between the upper box 1 and the lower box 2, and the filling mold 3 is an annular frame Die, the annular frame mold is that four templates 4 are connected.

Abstract

The sandwiched member for concrete includes one upper box board, one lower box board and one filling formwork between the upper box board and the lower box board, and features that the filling formwork is one annular frame formwork formed with at least two connected formworks. The present invention is suitable for in-situ cast or pre-stressed reinforced concrete hollow floor slab, roof, wall, foundation slab and hollow bridge, especially hollow flat floor slab.

Description

(1) Technical field [0001] The invention relates to a sandwich core member for concrete. (2) Background technology [0002] At present, most of the buildings with brick-concrete structure and frame structure use prefabricated hollow-core slabs as floor slabs. This kind of slabs has the advantages of fast construction speed and low cost, but because there is no firm connection between the two adjacent prefabricated hollow slabs , Only cement mortar is used to fill the gaps, so not only is the integrity poor, which is not conducive to earthquake resistance, but also cracks and water seepage often occur, causing great inconvenience and psychological pressure to the residents. In order to solve the above problems, many buildings adopt the method of cast-in-place concrete floor (hollow, solid). Although the cast-in-place concrete floor has solved the problems of earthquake resistance and cracking, a large number of formwork must be used during construction, which not only increa...
