The mold is characterized in that the linear control mold of the main arch ring has a stable structure because of triangular stability; the structure has high resistance to deformation; and the problem of difficult linear control of the main arch ring can be solved effectively.
Description
Technical field
The present invention relates to cast-in-situ steel reinforced concrete arch bridge and main arch ring technical field of construction, is specifically related 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 is frequently run onto the linear unmanageable problem of arch ring in the work progress of main arch ring, encircles particularly in clay model in the construction method of tire.Because the method for hanging wire construction has instability and difficulty to control, bring great inconvenience to construction, usually because arch tire and bed die are linear inaccurate, cause whole main arch ring alignment control bad, affect the presentation quality of arch bridge.
Summary 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 linear problem rambunctious in main arch ring work progress.
In order to solve above-mentioned technical problem, the technical scheme is that
nullA kind of main arch ring geometric control mould，Including the main muscle in top in the same plane、The main muscle in the end、Multiple first chevron and multiple second chevron，Push up the main muscle of main muscle and the end to form all in accordance with main arch ring span and camber bending，Push up the radial spacing between the main muscle of main muscle and the end equal to the main arch ring thickness removing top side protective layer，Push up the arc area formed between the main muscle of main muscle and the end and the main arch ring shape removing top side protective layer to coincide，The opening of the first chevron and the second chevron is the main muscle end of towards all，Arcuately zone length direction，First chevron and the second chevron are sequentially alternately arranged，The tip of the first chevron is fixing with the main muscle in top to be connected，Two openings of the first chevron are all fixing with the main muscle in the end to be connected，Two openings of the second chevron are all fixing with the main muscle in the end to be connected，The fixed connection point of two adjacent open end and the main muscle in the end that are belonging respectively to the first chevron and the second chevron overlaps.
Above-mentioned main arch ring geometric control mould, the symmetrical center line of the first chevron and the equal radial arrangement of symmetrical center line of the second chevron.
Above-mentioned main arch ring geometric control mould, for being positioned at first chevron at arc area length direction two ends, its most advanced and sophisticated fixing with main muscle end, top is connected, and an opening is fixed with main muscle end, the end and is connected, and another opening is fixing with the main muscle in the end to be connected.
Above-mentioned main arch ring geometric control mould, the second chevron is little compared with the first chevron, and the second chevron is most advanced and sophisticated to be pushed up between main muscle and the main muscle in the end.
Above-mentioned main arch ring geometric control mould, many compared with the second chevron one of the first chevron.
Pushing up and adopt the first chevron to connect between the main muscle of main muscle and the end, the first chevron and the triangle structure of main muscle, bulk strength is high, and the second chevron is same with the triangle structure of main muscle, improves bulk strength further.The stability utilizing triangle makes main arch ring alignment control mould structure consolidate, and resistance capacity to deformation is strong, it is possible to the effective problem solving main arch ring alignment control difficulty.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in more detail:
Fig. 1 is the structural representation of the present invention.
In figure: 1 pushes up main muscle, the 2 main muscle in the end, 3 first chevron, 4 second chevron.
Detailed description of the invention
As it is shown in figure 1, main arch ring geometric control mould includes the main muscle in top in the same plane 1, the main muscle in the end 2, multiple first chevron 3 and multiple second chevron 4.Push up the main muscle of main muscle and the end to form all in accordance with main arch ring span and camber bending; push up the radial spacing between the main muscle of main muscle and the end equal to the arch ring thickness removing top side protective layer, push up the arc area formed between the main muscle of main muscle and the end and the main arch ring shape removing top side protective layer and coincide.The opening of the first chevron and the second chevron is main muscle, arcuately zone length the direction end of towards all, and the first chevron and the second chevron are sequentially alternately arranged.The tip of the first chevron is fixing with the main muscle in top to be connected, two openings of the first chevron are all fixing with the main muscle in the end to be connected, two openings of the second chevron are all fixing with the main muscle in the end to be connected, and the fixed connection point of two adjacent open end and the main muscle in the end that are belonging respectively to the first chevron and the second chevron overlaps.
Specifically, the equal radial arrangement of symmetrical center line of the symmetrical center line of the first chevron and the second chevron.
Specifically, for being positioned at first chevron at arc area length direction two ends, its most advanced and sophisticated fixing with main muscle end, top is connected, and an opening is fixed with main muscle end, the end and is connected, and another opening is fixing with the main muscle in the end to be connected.
Specifically, the second chevron is little compared with the first chevron, and the second chevron is most advanced and sophisticated to be pushed up between main muscle and the main muscle in the end.
Specifically, many compared with the second chevron one of the first chevron.
Main arch ring geometric control Mold Making process:
First the main muscle in the end is made according to main arch ring span and camber; main arch ring thickness deducts top side protective layer thickness and is the radial spacing pushed up between main muscle and the main muscle in the end; then make and push up main muscle; pushing up and adopt the first chevron connection, the first chevron and the triangle structure of main muscle between the main muscle of main muscle and the end, bulk strength is high; finally; second chevron is connected with main muscle, and the second chevron is same with the triangle structure of main muscle, improves bulk strength further.Mould adopts the modelling of simply supported beam, has stable firmly characteristic, and has simple in construction, the feature of use light, easily controllable.
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 and just can find out deviation, thickness of protection tier can also be controlled in the process that arch ring reinforcing bar side is pricked.It is particularly suited in the method that clay model encircles tire method construction main arch ring, both can be used to control the linear of bottom arch tire, and the linear of bed die can have been controlled again and can also control thickness of protection tier, decrease the error problem that hanging wire construction brings.
