Abstract
Provided is a rod type center-dividing gauge, belonging to the bridge engineering field. The rod type center-dividing gauge is characterized in that: one end of the long rod is provided with carving nails while the other end of the long rod is provided with a sleeve, with carving nails arranged upon the sleeve; further provided is a bolt hole; and the bolt hole makes the sleeve fixed upon the long rod via a nut. The rod type center-dividing gauge is easy to make and can utilize the local material. Compared with the center line measuring means of other forms, the rod type center-dividing gauge of the utility model, with convenient usage, is labor saving and time saving, provides precise measurement data, and facilitates checking.
Description
Technical field
The utility model relates to the science of bridge building field, particularly the center line off normal survey instrument used of a kind of high speed railway prefabricating box girder product inspection.
Background technology
Rule were one of indispensable admeasuring apparatus in a kind of high speed railway prefabricating box girder field during rod-type divided, and were used for beam-ends bearing center line through having drawn, found and the center line of the case back plate top surface that draws, conveniently to carry out the measurement of indexs such as case back plate center line off normal.
The utility model content
The purpose of the utility model is: through rule in a kind of rod-type branch are provided, make things convenient for the measurement of case back plate center line off normal index.
The utility model provides rule in a kind of rod-type branch; It is characterized in that: the structure of rule comprised stock, carves nail, sleeve pipe during said rod-type divided, and an end of stock is provided with carves nail, and the other end is with sleeve pipe; The outer wall centre position of sleeve is provided with carves nail; Carve the symmetrical side of nail and be provided with bolt hole, bolt hole is used to install nut, and sleeve pipe is fixed on the stock.
The beneficial effect of the utility model is: make simply, can gather materials on the spot; Easy to use, more other forms of center line admeasuring apparatus is time saving and energy saving; Measurement data is accurate, and conveniently checks.
Description of drawings
Fig. 1 is the synoptic diagram of rule during the utility model rod-type divides;
Fig. 2 is the use synoptic diagram of rule during the utility model rod-type divides.
Embodiment
Below in conjunction with accompanying drawing the utility model is done to further describe, as shown in Figure 1, the structure of rule comprised during the rod-type that is provided in the utility model one preferred embodiment divided: stock 1, carve nail 2,4, sleeve pipe 3, nut 5.
One end of said stock 1 is provided with carves nail 2, and the other end is with sleeve pipe 3, and the outer wall centre position of sleeve 3 is provided with carves nail 4, carves nail 4 symmetrical sides and is provided with bolt hole, and bolt hole is used to install nut 5, and sleeve pipe 3 is fixed on the stock 1.In this preferred embodiment; At first adopt the steel pipe of external diameter 2cm, wall thickness 2mm, length 4.4m to make; The long nail 2 of carving of steel pipe one end welding 30mm, outer side sleeve 3 adopts the steel pipe of external diameter 26mm, wall thickness 2mm, length 10cm, and follow closely 4 the quarter of weld length 27mm in the middle of the sleeve pipe 3; Carve nail 4 symmetrical sides and make a bolt hole and nut 5 is installed, sleeve pipe 3 is fixed on the long steel pipe.
As shown in Figure 2, the use of rule was following during said rod-type divided: at first, with beam-ends bearing center lines 01 that draws such as span model and surveyor's staffs, 5cm place at the bottom of two bearing distance between center line beams is drawn the initial point 02 of arc as both sides; Then, rule one end nail at quarter 2 was fixed in picture arc initial point 02 place during a people will divide, and another people carries out the picture arc from back adjustment sleeve pipe 3 to correct position and fixing with nut 5, and each initial point is respectively drawn arc twice; At last, will carry out line, promptly find the top board center line 04 of case beam at the intersection point 03 of the drawn camber line of deck.
The preferred embodiment that the above is merely the utility model is not in order to limit the application range of the utility model; All other do not break away from the equivalence of being accomplished under the essence that the utility model discloses and change or modify, and all should be included in following claims scope.
