Description
Technical Field
The utility model relates to an improve shear force nail positioning accuracy's instrument, this instrument belongs to steel construction technical field.
Background
Shear nails are components designed to resist shear forces. When the beam and the plate are bent under the action of vertical load, the shearing force (horizontal direction) of the beam and the plate and the axial surface is the largest, the overlapped surface of the overlapped beam and plate members is just at (or close to) the position, and a plurality of shearing force nails are arranged to resist the shearing force so as to ensure that the bending resistance of the beam and the plate can be normally exerted.
The assembled steel-concrete composite beam is formed by connecting the precast concrete bridge deck with cast-in-place concrete at the shear nail part of the wing plate of the open-slot type steel box beam, and has extremely high requirement on the positioning precision of the shear nail welding.
The commonly used shear nail welding process is: and positioning the shear nails on the top plate of the steel beam by using ink fountain elastic cross-shaped grid lines. Although the grid cross points are accurate, the shear nails are welded without limitation, and workers cannot be accurately positioned at the cross point position during welding, so that the welding positioning accuracy of the shear nails is not high enough, and the requirement of the assembled steel-concrete composite beam on the positioning accuracy of the shear nails cannot be met.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an improve shear force nail positioning accuracy's instrument to satisfy the positioning accuracy requirement of shear force nail in the steel-concrete composite beam in hope.
In order to achieve the above object, the utility model discloses a technical scheme be an instrument of improvement shear force nail positioning accuracy, and this instrument utilizes the shear force nail template to improve shear force nail positioning accuracy, and the shear force nail template includes first draw-in groove 1, second draw-in groove 2, connects I-steel 3, steel sheet 4 and shear force nail locating hole 5. Punching shear pin positioning holes 5 on the steel plate 4 according to the positions of the shear pins; connecting the two steel plates 4 together through the connecting I-shaped steel 3; the second clamping groove 2 is welded on the connecting I-steel 3, and the shear nail template is fixed by the second clamping groove 2 and the first clamping groove 1 together.
The section structure of the shear nail positioning hole 5 is a multi-section continuous closed circular arc reducing hole, the radius of a middle section circular arc of the circular arc reducing hole is larger than that of the top and the bottom, and the diameter of the bottom circular arc is larger than that of the top.
Compared with the prior art, the positioning precision of the shear nails installed through the shear nail templates can be greatly improved, and the requirement on the positioning precision of the shear nails in the steel-concrete composite beam can be met.
Drawings
Fig. 1 is a schematic diagram of a shear pin template structure.
In the figure: 1. the first clamping groove 2, the second clamping groove 3, the connecting I-steel 4, the steel plate 5 and the shear pin positioning hole.
Detailed Description
As shown in fig. 1, the shear pin positioning accuracy is improved by using a shear pin template, and the shear pin template comprises a first clamping groove 1, a second clamping groove 2, a connecting i-steel 3, a steel plate 4 and a shear pin positioning hole 5.
In order to meet the requirements of ensuring the positioning accuracy of the shear nail and facilitating the demolding of the shear nail template, the section structure of the shear nail positioning hole 5 is a multi-section continuously closed circular arc reducing hole, the circular arc radius of the middle section of the circular arc reducing hole is larger than the circular arc reducing holes in the top and the bottom, and the circular arc reducing hole in the bottom is larger than the circular arc reducing hole in the top; the inner side is the positioning position of the shear pin, the outer side is a die withdrawal opening, and the size is determined according to the type of the shear pin. The size and the position of the shear nail positioning hole 5 are determined according to specific construction conditions.
The method comprises the following steps of (1) initially installing, placing a steel plate 4 with shear pin positioning holes 5 at a corresponding position according to a design drawing; welding the first clamping groove 1 on a steel plate 4, and fixing the shear nail template in the longitudinal direction by using a diaphragm plate of the steel-concrete composite beam; placing the connecting I-steel 3 welded with the second clamping groove 2 in the middle of the shear nail template, and fixing the shear nail template in the transverse direction by using the second clamping groove 2; and the shear nail template is installed and welded.
After the shear nails are welded, the connecting I-steel 3 welded with the second clamping grooves 2 is taken up, and the transverse fixing effect of the shear nail template disappears; and taking out the steel plate 4 with the shear nail positioning hole 5 through a die stripping opening of the shear nail positioning hole 5, and finishing the die stripping of the shear nail die plate.
The device has the advantages that: 1. the positioning accuracy of the shear nail welding is ensured; 2. easy dismounting, repeatedly usable.
