Description

Exterior wall template

Technical Field

The invention relates to a concrete template, in particular to a template for pouring an outer wall.

Background

In concrete foundation construction, in the formation of a concrete wall or column, a set of formworks are connected together in various ways at intervals to define a grouting space, the grouting space is poured with concrete to form the concrete wall or column, and each formwork is removed after the concrete is solidified, and two formworks are usually locked and fixed between two opposite formworks at intervals by a fixing piece.

However, in a special construction environment, for example, when a concrete foundation is constructed near an obstacle (another building), it is not easy for a constructor to perform a formwork (or scaffold) erection operation between the obstacle and a pre-poured concrete foundation area, and thus there is not enough space on the outer side of a predetermined concrete foundation (wall) structure to support the structure of the outer formwork, so that the construction position of the concrete foundation must be retracted, which inevitably reduces the effective use space inside the building.

See taiwan patent publication No. M528347 "metal form for building", which is directed to a design of a non-detachable metal form for exterior wall concrete foundation pouring, wherein a rectangular metal plate is used as an exterior wall surface of a building, the rectangular metal plate includes an inner surface and an outer surface which are separated from each other, a concave portion is formed on the inner surface, the concave portion includes a plurality of nuts welded therein, a peripheral wall is formed around the concave portion, the concave portion is provided with a plurality of reinforcing rods and the plurality of nuts are screwed by a plurality of bolts, so that grouting spaces with consistent intervals are formed between the rectangular metal plate and an interior side wood form of the building, and the rectangular metal plate is used as a non-detachable form, so that the structural strength of the exterior wall is increased, and the grouting spaces with consistent intervals are formed between the rectangular metal plate and the wood form, so that the thickness of the manufactured exterior wall is uniform.

The disassembly-free design in the prior art can save construction space and inconvenience in disassembly by avoiding erection of a scaffold, but the size of the disassembly-free design is specially customized, and a nut needs additional welding processing, so that the disassembly-free design is quite inconvenient in implementation; for example, assuming that the prepared width of the rectangular metal plate is designed to be 1 meter in size and the width of the precast concrete outer wall is 8.5 meters, the additional 0.5 meter size would be specifically customized. In construction, because the concave part of the rectangular metal plate is bent and formed by a large-scale machine, a constructor needs to specially order the rectangular metal plate with a special width in advance for construction, so that the material preparation is quite inconvenient; furthermore, the nuts are fixed by spot welding, which is problematic in that the strength is insufficient, and after cement mortar is poured into the grouting space, the nuts for screwing the bolts bear the tensile force generated after the load, and if the welding point fracture condition of the nuts occurs, the stability of the template construction is seriously affected.
