The invention relates to a formwork device for a wall, in particular to a formwork device and a manufacturing method capable of reducing the construction cost of a wall structure.

The conventional method of constructing a wall structure by grouting generally uses a plurality of templates to construct a separated inner mold and an outer mold, and the inner mold and the outer mold are connected by most tie rods, so that the inner mold and the outer mold form a Grouting space to provide grouting to form a wall. Before grouting, steel bars and pipelines are usually arranged in the grouting space, and most of the support members are used to lean against the outside of the inner mold and the outer mold obliquely so that the two side molds have sufficient lateral support strength to withstand the poured concrete. The resulting lateral pressure. However, the conventional method of making walls must generally reserve space for erection of formwork and supports on the inside or outside of the wall, resulting in a reduction in building space. Especially when the wall of the building under construction is adjacent to the wall of another building, the oblique erection of the support will inevitably have a negative impact on the size / space of the building.

Occasionally constitute the first template 12. A support space 30 is defined between two adjacent upright frame bars 28 to provide a corresponding support unit 18 to accommodate, and the frame bars 28 have a plurality of screw holes 34 arranged at intervals in accordance with their height direction, and the screw holes 34 extend Formed on the inner surface 24 of the first template 12, the screw hole 34 is used to provide an end corresponding to the connecting rod 16 for locking. In this embodiment, under consideration of the lateral pressure generated when the frame 28 is subjected to pouring concrete when the frame 28 is implemented, the inside of the frame 28 may have a U-shaped reinforcing frame 32 and the reinforcing frame 32 A screw cap 341 is internally fixed to provide the screw hole 34. Of course, as for the material and thickness of the frame 28, The reinforcement frame 32 can be exempted from implementation when the strength is changed. In a feasible embodiment, the nut 341 is fixed on the inner surface 24 of the first template 12. Furthermore, two sides of the outer end of the frame strip 28 each have a wing portion 36 extending along the lateral direction, and each wing portion 36 faces the outer surface 26 of the first template 12 and defines a groove 38 between the first template 12 ( (See FIG. 2), so that each side of each support space 30 has a groove 38, and each groove 38 extends along a direction perpendicular to the transverse direction and the longitudinal direction, that is, each groove 38 is formed by a first template. The upper end of 12 extends to the lower end of the first template 12, and the supporting space 30 is defined by the grooves 38 between two adjacent upright frame bars 28.

In this embodiment, the second formwork 14 is composed of an upright wooden formwork and the second formwork 14 is provided with a plurality of perforations 40 (see FIG. 6). Each connecting rod 16 is a screw and extends through the second template 14 along the longitudinal direction. Each connecting rod 16 includes a separated first section 42 and a second section 44. The first section 42 of the connecting rod 16 is locked into a corresponding screw hole 34 and the second section 44 of the connecting rod 16 passes through one of the second template 14. Corresponding to the perforation 40, it is fixed to the tightening nut 48 with a positioning washer 46. In addition, a plurality of supporting members (not shown) can be used to abut against the outside of the second formwork 14 so that the second formwork 14 has sufficient lateral support strength to withstand the lateral pressure generated when the concrete is poured.

Each support unit 18 may be a plate with sufficient strength or a grid structure plate. In this embodiment, each support unit 18 includes a plurality of cross bars 50 vertically separated and a combination of the plurality of cross bars 50. At least one connecting rope 52. In this embodiment, each cross member 50 is a pipe body and includes a first end 54 and a second end 56 that are laterally separated from each other, and the first end 54 and the second end 56 of each cross member 50 They are respectively located in one of the grooves 38 corresponding to the supporting space 30, and the width of each transverse material 50 in the transverse direction is slightly larger than the transverse distance of the adjacent two upright frame bars 28, so that each transverse material 50 can be diagonally supported against Two adjacent upright frame bars 28 are fixed. In the present embodiment, each supporting unit 18 includes two connecting ropes 52 separated in the lateral direction, and each connecting rope 52 passes through the plurality of transverse bars 50 in the straight direction and is combined with the plurality of transverse bars 50. (The connecting rope 52 may be fixed in combination with the plurality of cross bars 50 using, for example, a knot or other known techniques).

(It is not supported diagonally between the ground and the first formwork). Therefore, the reserved space between the first formwork 12 and the wall 62 can be effectively reduced. At the same time, since the support unit 18 can The support space 30 of the template 12 can be easily taken out for repeated use. This results in wasted support elements, which can reduce construction costs.

The invention further provides a wall manufacturing method, which includes: providing a formwork device 10 as in the above embodiment; grouting in the grouting space 20 of the formwork device 10 to form a wall structure; and after the grouting is completed, The support unit 18 is lifted upward from the received support space 30 in this direction and removed. The construction method according to the present invention is particularly applicable to a place where a wall to be produced is adjacent to other buildings. In the production and implementation of the wall, not only can the outer formwork have sufficient lateral supporting force, but also it does not need to reduce the building space. Reach the effect of recycling support elements.
