Description
Technical field
The present invention relates to cast-in-situ steel reinforced concrete arch bridge and main arch ring technical field of construction, and in particular to a kind of main arch ring outward appearance
Alignment control mould.
Background technology
In the work progress of arch bridge, main arch ring construction is the emphasis of bridge construction, and in the work progress of main arch ring
The linear unmanageable problem of arch ring is frequently run onto, especially in the construction method of clay model arch tire.Because the side of hanging wire construction
Method has unstable and difficulty to control, and great inconvenience is brought to construction, usually because arch tire and bed die are linear inaccurate, causes
Whole main arch ring alignment control is bad, influences the presentation quality of arch bridge.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of main arch ring geometric control mould, can effectively solve master
Linear problem rambunctious in arch ring work progress.
In order to solve the above-mentioned technical problem, the technical scheme is that：
A kind of main arch ring geometric control mould, including top cage bar, bottom cage bar, multiple first in the same plane
Chevron and multiple second chevrons, top cage bar and bottom cage bar are formed all in accordance with main arch ring span and camber bending, push up cage bar and bottom
Radial direction spacing between cage bar is equal to the main arch ring thickness of removal top side protective layer, the arc formed between top cage bar and bottom cage bar
Region with removal top side protective layer main arch loop-shaped coincide, the opening of the first chevron and the second chevron towards bottom cage bar,
Arcuately zone length direction, the first chevron and the second chevron are sequentially alternately arranged, and tip and the top cage bar of the first chevron are consolidated
Fixed connection, two openends of the first chevron are fixedly connected with bottom cage bar, and two openends of the second chevron are solid with bottom cage bar
Fixed connection, two adjacent open ends for being belonging respectively to the first chevron and the second chevron overlap with the fixed connection point of bottom cage bar.
The symmetrical centre of above-mentioned main arch ring geometric control mould, the symmetrical center line of the first chevron and the second chevron
The equal radial arrangement of line.
Above-mentioned main arch ring geometric control mould, comes for the first chevron positioned at arc area length direction two ends
Say, its tip is fixedly connected with cage bar end is pushed up, and an openend is fixedly connected with bottom cage bar end, another openend and bottom
Cage bar is fixedly connected.
Above-mentioned main arch ring geometric control mould, the second chevron is small compared with the first chevron, and the second chevron tip is located at top
Between cage bar and bottom cage bar.
Above-mentioned main arch ring geometric control mould, the first chevron is more one compared with the second chevron.
It is whole using the connection of the first chevron, the first chevron and the triangle structure of cage bar between top cage bar and bottom cage bar
Body intensity is high, the second chevron equally with the triangle structure of cage bar, further improve bulk strength.Using the stabilization of triangle
Property consolidate main arch ring alignment control mould structure, resistance capacity to deformation is strong, can effectively solve main arch ring alignment control difficult
Problem.
Brief description of the drawings
The present invention is described in more detail below in conjunction with the accompanying drawings：
Fig. 1 is structural representation of the invention.
In figure：1 top cage bar, 2 bottom cage bars, 3 first chevrons, 4 second chevrons.
Specific embodiment
As shown in figure 1, main arch ring geometric control mould include top cage bar 1 in the same plane, bottom cage bar 2,
Multiple first chevrons 3 and multiple second chevrons 4.Top cage bar and bottom cage bar are formed all in accordance with main arch ring span and camber bending,
Radial direction spacing between top cage bar and bottom cage bar is equal to the arch ring thickness of removal top side protective layer, shape between top cage bar and bottom cage bar
Into arc area with removal top side protective layer main arch loop-shaped coincide.The equal direction in opening of the first chevron and the second chevron
Bottom cage bar, arcuately zone length direction, the first chevron and the second chevron are sequentially alternately arranged.First chevron tip with
Top cage bar is fixedly connected, and two openends of the first chevron are fixedly connected with bottom cage bar, two openends of the second chevron with
Bottom cage bar is fixedly connected, and is belonging respectively to two adjacent open ends and the fixed connection point of bottom cage bar of the first chevron and the second chevron
Overlap.
Specifically, the equal radial arrangement of the symmetrical center line of the symmetrical center line of the first chevron and the second chevron.
Specifically, for the first chevron positioned at arc area length direction two ends, its sophisticated and top cage bar end
It is fixedly connected, an openend is fixedly connected with bottom cage bar end, and another openend is fixedly connected with bottom cage bar.
Specifically, the second chevron is small compared with the first chevron, and the second chevron tip is located between top cage bar and bottom cage bar.
Specifically, the first chevron is more one compared with the second chevron.
Main arch ring geometric control Mold Making process：
Bottom cage bar is made according to main arch ring span and camber first, main arch ring thickness subtracts top side protective layer thickness and is top
Radial direction spacing between cage bar and bottom cage bar, then makes top cage bar, is connected using the first chevron between top cage bar and bottom cage bar
Connect, the first chevron and the triangle structure of cage bar, bulk strength is high, and finally, the second chevron is connected with cage bar, the second V-arrangement
Part equally with the triangle structure of cage bar, further improve bulk strength.Mould uses the modelling of simply supported beam, with stabilization
Firm characteristic, and with simple structure, it is light, easily controllable the characteristics of use.
Main arch ring geometric control method：
In bed die work progress, main arch ring geometric control mould is stuck on arch tire or bed die can just be found out partially
Difference, thickness of protection tier can also be controlled during arch ring reinforcing bar side is pricked.It is particularly suited for clay model arch tire method construction
In the method for main arch ring, both can be used to control bottom to encircle the linear of tire, can control the linear of bed die that reinforcing bar can also be controlled to protect again
Covering thickness, reduces the error problem that hanging wire construction brings.
