Description

Wall formwork device and manufacturing method

Technical Field

The present invention relates to a wall form device, and more particularly, to a form device and a method for reducing the construction cost of a wall structure.

Background

In a conventional method of constructing a wall structure by grouting, a plurality of forms are used to construct an inner form and an outer form which are separated from each other, and a plurality of tie rods are used to connect the inner form and the outer form, so that a grouting space is formed between the inner form and the outer form to form a wall body by grouting. Before grouting, steel bars and pipelines are usually arranged in the grouting space, and a plurality of supporting members are obliquely abutted against the outer sides of the inner side mold and the outer side mold so that the two side molds have enough lateral supporting strength to bear the lateral pressure generated when concrete is poured. However, the conventional wall manufacturing method generally requires a space for installing the form and the supporting member on the inner side or the outer side of the wall, resulting in a reduction of the space of the building. The diagonal construction of the support members necessarily has a negative effect on the size/space of the building, particularly when the wall of the building being constructed is adjacent to the wall of another building. Or some improving methods do not detach the formwork and the supporting piece of the outer side mold after grouting is finished, so that the outer side mold and the supporting piece of the wall can be adjacent to the wall body of another building as much as possible to avoid excessively reducing the space of the frame building. However, the number of supports is considerable, and the supports that are not removed result in a waste of useful material, which in turn increases the construction costs.

The first form 12 and the second form 14 are spaced apart by a predetermined distance in a longitudinal direction (see fig. 1), and the first form 12 and the second form 14 are coupled by the plurality of coupling rods 16 such that a grouting space 20 is defined between the first form 12 and the second form 14 to provide grouting for forming a wall.

In the present embodiment, the first form 12 is formed by connecting a plurality of upright metal plates 122, and each plate 122 is formed with a wave-shaped protrusion 22 for increasing strength. In a possible embodiment, the first template 12 is constituted by a single plate. First form 12 has opposed inner and

outer surfaces

24 and 26, inner surface 24 of first form 12 facing second form 14, outer surface 26 of first form 12 being provided with a plurality of upstanding webs 28 (see fig. 2) spaced apart in a transverse direction perpendicular to the longitudinal direction; in one possible implementation step, after the plurality of upright frame strips 28 are positioned and fixed in a laterally spaced manner, a plurality of plates 122 are disposed and combined between two adjacent upright frame strips 28 to form the first form 12. A supporting space 30 is defined between two adjacent upright frame strips 28 to accommodate a corresponding supporting unit 18, and the frame strips 28 have a plurality of screw holes 34 spaced apart from each other along the height direction thereof, the screw holes 34 are formed extending from the inner surface 24 of the first mold plate 12, and the screw holes 34 are used for providing an end of a corresponding connecting rod 16 to be locked therein. In the embodiment, under the condition of considering the lateral pressure generated when the frame strip 28 is poured with concrete, the inside of the frame strip 28 may have a reinforcing frame 32 with a U-shaped cross section, and a nut 341 is fixed in the reinforcing frame 32 to form the screw hole 34, although the reinforcing frame 32 is not required to be implemented if the material and thickness of the frame strip 28 are changed to improve the strength thereof. In a possible embodiment, the nut 341 is fixed to the inner surface 24 of the first template 12. Furthermore, the two sides of the outer end of the frame strip 28 are respectively provided with a wing 36 extending along the transverse direction, each wing 36 faces the outer surface 26 of the first form 12 and defines a groove 38 (see fig. 2) with the first form 12, so that two sides of each supporting space 30 are respectively provided with a groove 38, each groove 38 extends along a direction perpendicular to the transverse direction and the longitudinal direction, that is, each groove 38 extends from the upper end of the first form 12 to the lower end of the first form 12, and the supporting space 30 is defined between the grooves 38 of two adjacent upright frame strips 28.

In this embodiment, the second form 14 is formed from a single upstanding wooden form and the second form 14 is provided with a plurality of perforations 40 (see fig. 6). Each connecting rod 16 is a threaded rod and extends through the second die plate 14 along the longitudinal direction. Each tie bar 16 includes a first section 42 and a second section 44 that are spaced apart, the first section 42 of the tie bar 16 being keyed to a corresponding threaded hole 34 and the second section 44 of the tie bar 16 passing through a corresponding aperture 40 of the second form 14 and secured thereto by a retaining washer 46 and a lock nut 48. In addition, a plurality of support members (not shown) may be utilized to abut against the outside of the second form 14 to provide sufficient lateral support strength to the second form 14 to withstand lateral pressure forces generated when pouring concrete.

Each support element 18 may be a sheet of sufficient strength or a lattice-structured sheet; in the present embodiment, each supporting unit 18 comprises a plurality of cross members 50 separated in the vertical direction and at least one connecting rope 52 connecting the plurality of cross members 50, in the present embodiment, each cross member 50 is a tube and comprises a first end 54 and a second end 56 separated in the horizontal direction, the first end 54 and the second end 56 of each cross member 50 are respectively located in one of the grooves 38 of the corresponding supporting space 30, and the width of each cross member 50 in the horizontal direction is slightly larger than the horizontal distance between two adjacent upright frame strips 28, so that each cross member 50 can be obliquely supported and supported between two adjacent upright frame strips 28 to be fixed. In the present embodiment, each supporting unit 18 comprises two connecting strings 52 separated in the transverse direction, and each connecting string 52 passes through the plurality of crossbars 50 along the longitudinal direction and is combined with the plurality of crossbars 50 (the connecting strings 52 and the plurality of crossbars 50 can be combined and fixed by using, for example, knots or other known techniques). Further, each support unit 18 is installed in a corresponding support space 30 in a suspended manner such that the upper section 58 of each connecting string 52 protrudes from the upper end 60 of the first formwork 12. Therefore, the user can hold the upper sections 58 of the two connecting ropes 52 to install each supporting unit 18 in the corresponding supporting space 30 along the vertical direction, and can easily lift each supporting unit 18 from the accommodated supporting space 30 along the vertical direction to achieve the purpose of detachment, and the inclined supporting between each rail 50 and the transverse direction is not horizontal, so that when the supporting unit 18 is lifted upwards to detach, the end of the rail 50 at the higher position can be smoothly taken out when being lifted.

In the formwork apparatus 10 according to the present invention, reinforcing bars and pipes (not shown) may be disposed in the grouting space 20 before grouting in the construction of the wall body. When concrete is poured into the grouting space 20, since the supporting unit 18 is disposed on the outer surface 26 of the first form (outer form) 12 and the first and second ends 54 and 56 of the plurality of rails 50 are positioned in the grooves 38 of the supporting space 30, the first form (outer form) 12 can bear the lateral pressure generated when the concrete is poured, thereby effectively preventing the occurrence of mold burst. On the other hand, after grouting and curing operations are completed, the second form (inner form) 14 may be removed to present the inner side wall of the wall structure, and the support units 18 suspended from the outer surface 26 of the first form 12 are lifted up from the received support space 30 to be removed while leaving the first form 12 as the outer side wall of the wall (i.e., the non-removed first form 12), to complete the wall.

As shown in fig. 1, when the formwork apparatus 10 of the present invention is constructed adjacent to a building 62, since the first formwork 12 is a non-dismantling formwork and the supporting unit 18 is disposed in the supporting space 30 of the first formwork 12 in an upright direction (not diagonally supported between the ground and the first formwork), a reserved space between the first formwork 12 and the wall 62 can be effectively reduced, and meanwhile, since the supporting unit 18 can be easily taken out from the supporting space 30 of the first formwork 12 after grouting is completed for reuse, waste of supporting components is not caused, and construction costs can be reduced.

The invention further provides a method for manufacturing the wall, which comprises the following steps: providing a template assembly 10 as in the previous embodiment; grouting in the grouting space 20 of the formwork device 10 to form a wall structure; and lifting the supporting unit 18 upward from the received supporting space 30 in the straight direction for removal after grouting is completed. The method is particularly suitable for the site where the wall body to be manufactured is adjacent to other buildings, and in the manufacturing implementation of the wall body, the outer side template can have enough lateral supporting force, the space of the building is not reduced, and the effect of recycling the supporting components can be achieved.
