Abstract

The invention discloses a box culvert template which comprises an inner template, an outer template, a lower rabbet template, an upper rabbet template, an inner die support and inner die back ridges. The inner template is installed on the inner side of the outer template, and a certain distance is reserved between the inner template and the outer template and used for concrete pouring. The lower rabbet template is located below the position between the inner template and the outer template. The upper rabbet template is located above the position between the inner template and the outer template. A space commonly defined by the outer template, the inner template, the upper rabbet template and the lower rabbet template is used for concrete pouring. The lower rabbet template is connected with the outer template and the inner template. The upper rabbet template is connected with the outer template, and a notch is reserved between the upper rabbet template and the inner template and used for concrete pouring. The box culvert template has the beneficial effects of being simple, practical and firm in structure, quick die release is achieved through ascent and descent of the inner die support, and meanwhile the inner template is convenient to install and detach.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a box culvert template. Background technique [0002] Box culverts refer to culverts built with reinforced concrete box-shaped pipe joints. Box culverts consist of one or more square or rectangular sections, generally made of reinforced concrete or masonry, but reinforced concrete is widely used. When the span is less than 4m, box culverts are used. For pipe culverts, reinforced concrete box culverts are An inexpensive alternative, the piers, upper and lower slabs are all poured in unison. [0003] Formwork is required for pouring concrete box culverts, but the formwork is not only large in size, but also heavy, which leads to slow loading and demoulding speeds, thereby affecting production efficiency. Contents of the invention [0004] In view of this, the object of the present invention is to propose a box culvert template to improve the demoulding speed. [0005] Bas...
