Description

Wall formwork components

The invention relates to a formwork component of a wall, in particular to a formwork component suitable for pouring external walls.

In the construction of concrete foundations, the formation of concrete walls or columns generally connects two separated formwork together to define a grouting space in which concrete can be poured to form concrete walls or columns. After the concrete is consolidated, each formwork is removed. A plurality of separate fixing members are usually used to lock and fix the two opposite templates.

However, for special construction environments (such as the environment where the concrete construction site is close to an obstacle or another building), the construction personnel will not be easy to implement the formwork (or eagle) between the obstacle (building) and the pre-filled concrete foundation area Erecting work), and there will not be enough space on the outside of the concrete foundation (wall) structure to erect the structure that can support the outer formwork. Therefore, the construction location of the concrete foundation (wall) must usually be retracted, resulting in a reduction in the effective use of space inside the building.

Taiwan's new patent announcement No. M528347 discloses a metal formwork for construction, which is a non-dismantling metal formwork designed for the pouring of concrete foundations of external walls. The formwork includes a rectangular metal plate as the outer wall of the building. The rectangular metal plate includes an inner surface and an outer surface. The inner surface forms a recess, and the recess is provided with a plurality of reinforcing rods and a plurality of nuts that can provide a plurality of bolts. A peripheral wall is formed around the recess. In this way, a grouting space with a uniform spacing is formed between the metal plate and an inner wooden formwork, so that the thickness of the manufactured outer wall is uniform.

However, the concave part of the above-mentioned free-form metal formwork must be bent and formed by a large machine. The builder must order a rectangular metal plate with a special width in advance to cope with the construction, which causes considerable inconvenience in preparation. In addition, when the cement mortar is poured into the grouting space, the nut that provides bolting will bear the tensile force generated by the grouting load. The nut fixed on the metal plate has the problem of insufficient strength, and the nut may break or fall off, which seriously affects the stability of the formwork.

Therefore, the main object of the present invention is to provide a formwork assembly for a wall, which has sufficient compressive strength and can withstand the lateral pressure generated when concrete is poured, and is particularly suitable for construction of a wall adjacent to another building The implementation of the location of the objects achieves the advantages of easy erection work and enhances the stability of the template erection.

The at least one plate body is installed between two adjacent pillars, the plate body includes a first side end and a second side end separated in the lateral direction, and the first side end and the second side end of the plate body are respectively accommodated In one of the adjacent two pillars corresponding to the groove.

In an embodiment, each pillar includes two laterally opposite side walls, and each pillar has a through-groove therein. The through-groove extends in a straight direction and is defined between the inner wall, the outer wall, and the two side walls. The straight direction is perpendicular to the transverse direction and the longitudinal direction, and each groove extends along the straight direction and is defined between the inner wall, the outer wall, and one of the side walls.

In a preferred embodiment, the at least one coupling member includes a plurality of coupling members separated along the straight direction, each coupling member is a nut with a screw hole, and the screw hole provides the end locking of the connecting rod.

In a preferred embodiment, a reinforcement frame is provided in the through slot of each pillar, the reinforcement frame has an inner plate corresponding to the inner wall, and the plurality of coupling members are installed in the reinforcement frame and fixed on the inner plate, The inner wall of each pillar is provided with a plurality of connecting holes, and the screw hole of each coupling piece communicates with a connecting hole on each pillar, so that the end of the connecting rod passes through the corresponding connecting hole and locks into the screw hole.

In an embodiment, each coupling member is a connecting hole provided on the inner wall of each pillar, and each connecting hole has an internal thread to provide the end locking of the connecting rod.
