Problems solved by technology

[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 will easily lead to concrete grout leakage inside; due to the vertical construction, the high concrete pressure in the formwork will easily lead to deformation of the formwork, which will deform the appearance of the finished product, seriously affect the construction quality of the culvert tunnel, and also bring great harm to the construction personnel. trouble

Embodiment Construction

[0018] of the present invention Molds for shaped components. It is formed by the combination of side form 2, side form 4 with support and side plate fixing frame 5 Plate side molds. Blocking mold 6, chair-shaped bottom mold 7, trapezoidal bottom mold 8, bottom plate 1, and support frame 3 form the bottom support formwork system, which is installed below the mold frame template, and side mold 4 is fixed on the chair-shaped bottom mold 7 by bolts. The side molds together with the bottom support formwork system constitute the production A complete set of molds for the shape plate (as shown in Figure 3). The base plate 1 is a similar "Tian"-shaped skeleton welded by square steel pipes, and flat steel can be added to the skeleton, and a steel plate is welded on one side of the skeleton, and holes are drilled in its proper position so that the bolts are connected with the side form. Side form 2 is the skeleton similar to " day " " mesh " font that is welded into by square ste...

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 with a steel mold Shaped member moulds, which are used to make reinforced concrete culverts in precast factories Shaped member, which is formed by welding square steel pipe and steel plate; reinforced concrete culvert Form members and reinforced concrete culverts The combination of shaped components forms passages 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 will easily lead to concrete grout leakage inside; due to the vertical construction, the high concrete pressure in the formwork will easily lead to deformation of the formwork, which will deform the appearance of the finished product, seriously affect the construction quality of the culvert tunnel, and also...
