Embodiment Construction

[0018] The mold of the -shaped member of the present invention. The side mold of the "" plate is formed by combining the side mold (2), the side mold with support (4) and the side plate fixing frame (5). Block formwork (6), chair-shaped bottom plate formwork (7), trapezoidal bottom formwork (8), base plate (1), bracing frame (3) form bottom supporting formwork system, are installed in the below of mold frame formwork. Side mold (4) is bolted on the chair-shaped base plate form (7), and side mold forms the complete set of mold (as shown in Figure 3) of producing -shaped plate together with bottom supporting formwork system. Base plate (1) is the similar " field " shape skeleton that is welded into by square steel pipe, also can add welding flat steel in skeleton, cover welding steel plate at one side of skeleton, so that bolt is connected with side form in its proper position drilling. Side formwork (2) is the skeleton similar to " day " " mesh " font that is welded into by...

Abstract

The invention relates to a prefabricated reinforced concrete culvert T-shape mould, which can solve the problems of hard installment, hard control on the verticality and surface smoothness; loose connection between plates, and concrete leakage, etc. The invention comprises a bottom support, a bottom plate mould, and side plate moulds, while said mould is rectangle whose two sides are mounted with side moulds (2); and two ends are mounted with support side moulds (4); two ends of side mould (2) are mounted with side plate fixed skeletons (5); side moulds () and the support side mould (4) and the side plate fixed skeleton (5) form special-shaped side mould; the baffle mould (6), chair-shaped bottom plate mould (7) and the trapezium bottom mould (8) form the bottom support mould; and the side mould forms the whole mould with bottom support mould. The invention has simple structure and easy installment, which can save cost and labor force, to improve the construction speed and quality.

Description

technical field [0001] The invention relates to a prefabricated reinforced concrete culvert -shaped member mold of a steel mold, which is used to make a reinforced concrete culvert -shaped member in a prefabrication factory, which is formed by welding square steel pipes and steel plates; the reinforced concrete culvert -shaped member and Reinforced concrete culverts and culverts are combined to form passageways and culverts in traffic construction. Background technique [0002] As we all know, the existing construction of culverts and passageways adopts the overall formwork installed on site, and the formwork is formed by setting steel bars and pouring concrete. Close combination can easily lead to concrete grout leakage inside; due to the vertical construction, the high concrete pressure in the formwork will easily cause the formwork to deform, which will deform the appearance of the finished product, seriously affecting the construction quality of the culvert tunnel, an...
