Abstract
The invention belongs to the technical field of bridge ancillary work curtain board construction, and in particular relates to a vertical mould used for prefabricating a high speed railway bridge curtain board and a curtain board prefabricating method completed by using the vertical mould. With the adoption of the curtain board prefabricating method, the problems that chamfer bubbles are easily generated, one-step molding of the curtain board is relatively short and the installation efficiency is relatively low in the conventional bridge curtain board prefabricating method are solved. The vertical mould comprises a moulding board system and bearing systems, wherein the moulding board system comprises an arc-shaped side mould, an L-shaped side mould, a flat mould and a Z-shaped side mould sequentially connected end to end. The curtain board prefabricating method comprises the following steps of: excavating a foundation pit slot and installing the bearing systems; assembling each moulding board on the bearing systems; placing a curtain board reinforcement cage; coating the curtain board reinforcement cage by the arc-shaped side mould; and pouring concrete. With the adoption of the vertical mould and the curtain board prefabricating method, the defects of difficult control of the line shape of the curtain board, low work efficiency indexes, substandard appearance quality of the concrete, and the like of a cast-in-site method are avoided, the generation of the chamfer bubbles of the curtain board is avoided, the density degree of the concrete is ensured, the process is simple, the operation is easy, and the formation of streamlined operation is facilitated.
Description
Technical field
The invention belongs to the technical field of bridge appurtenant work shield construction, it is prefabricated with vertical die and use the shield method for prefabricating of its completion to be specifically related to a kind of high-speed railway bridge shield.
Background technology
In the high-speed railway bridge appurtenant work, shield is a kind of outer hanging hang structure of bridge flange plate, is connected to form whole steadiness structure through reserving anchor bar and bridge straight wall.Shield belongs to the concrete prefabricated element of bridge both sides of the edge, and as the stressed carrier is carrier of bridge railing and sound barrier, the quality of construction quality is related to the bridge presentation quality.
The bridge curtain board construction has two kinds of methods at present, and a kind of is cast-in-place method, promptly utilizes template to carry out template at the bridge flange plate edge on the spot and sets up, reinforcing bar binding, Template Location, cast-in-place concrete on the spot.This method exists manual work repeatedly to carry out formwork reinforcement, causes template deformation and precision not high easily, and the on-site concrete maintenance is not in place, and it is a lot of that prefabricated shield product poor flatness, color and luster differs, unfilled corner is fallen piece, has a strong impact on the integral bridge quality.A kind of in addition is horizontal shaking platform method, and it is prefabricated promptly to utilize horizontal template of level and vibration pedestal to carry out batch production, on shaking platform top template and paralell is set, and builds then.The method though can guarantee whole most of concrete packing, still can't be avoided the generation of shield upper surface chamfering place concrete great amount of bubbles in horizontal vibration processes; Surface quality is relatively poor, must carry out secondary and repair, and can not well satisfy quality requirement; In addition, this method receives the restriction of shaking platform owing to carry out operation in batch production; The shield one-shot forming is merely the number of shaking platform, has limited the production efficiency of bridge curtain board.
Summary of the invention
Goal of the invention of the present invention: existing bridge curtain board method for prefabricating is prone to produce local chamfering bubble and the shield one-shot forming is short and the lower problem of installation effectiveness in order to solve.
The present invention adopts following technical scheme to realize:

Described load bearing system comprises supporting frame and bearing plate, and bearing plate is provided with and is used for the screwed hole that is connected with the flange in the bottom of arc side form, " L " shape side form, flat-die and " Z " shape side form.
The panels outside of arc side form is provided with horizontal and vertical ribbed stiffener, and the panels outside of " Z " shape side form, " L " shape side form is provided with transverse stiffener.
High-speed railway bridge shield method for prefabricating uses the high-speed railway bridge shield prefabricated with the vertical die completion, and step is following:
1), the excavation pit groove, the bottom surface of foundation ditch groove is smooth, and the plurality of load bearing system is installed in the foundation ditch groove,
2), in the foundation ditch groove, arc side form, " L " shape side form, flat-die and " Z " shape side form are fitted together, and the bottom is connected with bolt on the bearing plate of load bearing system,
3), shield steel reinforcement cage that produce in factory is accomplished is placed within mounted " Z " shape side form, " L " shape side form and the flat-die,
4), with the arc side form with shield steel reinforcement cage parcel, and the arc side form carried out bolt and is connected with " Z " shape side form, " L " shape side form, the bottom of arc side form is connected with bearing plate,
5), the shield pre-embedded bolt is installed on the circular hole of " Z " shape side form,
6), casting concrete, when carrying out concrete vibrating, inlet gets into vibrating spear from the top of mould,
7), carry out concrete curing and form removal.
The present invention has following advantage:
Shortcomings such as the linear control of the shield of 1, having avoided cast-in-place method to exist is difficult, the work efficiency index is low, Surface Quality of Concrete is not up to standard.
2, adopt vertical die prefabricated, avoided the generation of shield chamfering place bubble, guaranteed concrete packing.
3, operation is simple, processing ease, and bolt connects and can guarantee installation accuracy, is convenient to form the streamlined operation.
