Description
Technical field
The utility model relates to a kind of control device of steel wire binding bar crudy.
Background technology
In the construction of reinforced concrete works, the processing steel wire binding bar adopts the method for craft or machining more.Adopt the mechanical bend steel wire binding bar, can reduce labor intensity, increase work efficiency and ensure the quality of products.Adopt manual moment reinforcement stirrup, have characteristics such as equipment is simple, moulding is correctly changeable, but labour intensity is big, efficient is low.The used reinforcing bar of common engineering when φ 10 is following, can make crooked by hand, use mechanical bend when φ 10 is above.No matter craft or machining, the crotch angle of the steel wire binding bar of machine-shaping, arc interior diameter, flat segments length all should satisfy design and code requirement.
Regrettably, do not have a kind of device that can control the steel wire binding bar crudy in the construction at present, there is the problem that is difficult to hold in the crudy of steel wire binding bar.
The utility model content
For addressing the above problem, the utility model provides a kind of steel wire binding bar quality control mould, can effectively control crotch angle, arc interior diameter, the flat segments length of steel wire binding bar, makes its processing reach design and code requirement.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of steel wire binding bar quality control mould, it is characterized in that: it comprises a foursquare base plate, the top of base plate is connected to the steel bar end of 16 φ 16mm at four jiaos of inboard and inboard evenly vertical weldings in four limits, equals the inner edge dead size of steel wire binding bar with the distance between any two steel bar end outer rims in one side.Four steel bar ends at four jiaos of places of base plate are respectively 75mm, 80mm, 100mm, four positioning strips vertical with diagonal of 120mm part welding along diagonal distance, and the length of above-mentioned four positioning strips is 100mm, the thick 5mm of being, the wide 20mm of being.
Above-mentioned base plate can be rectangle steel plate or concrete slab.
Above-mentioned positioning strip can be one section angle steel or one section steel plate bar.
The height of above-mentioned steel bar end can be 50mm～100mm.
The utility model is simple in structure, cheap, easy to use, can be easy to detect crotch angle, arc interior diameter and the flat segments length of multiple steel wire binding bar, guaranteed stirrup flat segments and arc interior diameter quality effectively, the quality that can control stirrup reaches design and code requirement.

The specific embodiment
Embodiment is referring to shown in Figure 1, this steel wire binding bar quality control mould, it is characterized in that: it comprises a foursquare base plate 1, and the top of base plate is connected to the steel bar end 2 of 16 φ 16mm at four jiaos of inboard and inboard even vertical weldings in four limits, and the height of above-mentioned steel bar end 2 is 50mm～100mm.Equal the inner edge dead size of steel wire binding bar 4 with the distance between any two steel bar end outer rims in one side.Four steel bar ends at four jiaos of places of base plate are respectively 75mm, 80mm, 100mm, four positioning strips vertical with diagonal of 120mm part welding along diagonal distance, and the length of above-mentioned four positioning strips is 100mm, the thick 5mm of being, the wide 20mm of being.Above-mentioned positioning strip can be one section angle steel or one section steel plate bar.Distance between positioning strip and the steel bar end is respectively the tested steel wire binding bar bending quality required standard distance of four kinds of different models.
Steel wire binding bar bending quality control method is as follows:
1,, utilizes the steel bar end 2 on the steel wire binding bar quality control mould, when I level steel end will be made 180 ° of crotches referring to Fig. 2, its crooked arc diameter should be less than 2.5 times of bar diameter, be D 〉=2.5d, straight portion length is not less than 3 times of bar diameter, i.e. L 〉=3d.
2, referring to Fig. 3, Fig. 4, utilize the steel bar end 2 on the steel wire binding bar quality control mould, when II level steel end will be done 90 ° or 135 ° bending, its bending diameter should not be less than 4 times of bar diameter, and straight portion length is determined by designing requirement; The bending diameter of bending place, bent-up bar middle part should be less than 5 times of bar diameter, i.e. D 〉=5d.
3, referring to Fig. 5, utilize the steel bar end 2 on the steel wire binding bar quality control mould, make stirrup with the I grade reinforcing steel, its end should be done the bending diameter of crotch, crotch should be greater than the steel bar stress diameter, and be not less than 2.5 times of stirrup diameter, the straight length of crotch is in 10 times of stirrup diameter, i.e. L=10d.The straight length of φ 6 steel wire binding bars is 75mm.
4, require the reinforcing bar shape correct, do not have the uneven phenomenon of warpage on the plane, must not there be the crack at bar bending point place.
The course of work of the present utility model: in reinforcing bar when construction processing, should be according to bar diameter to steel wire binding bar crotch angle, arc interior diameter, the on-the-spot line of flat segments length and adopt the axle center flexual center mould (machining) of different-diameter and different spanner (manual processing) carries out crudy and controls.
The stirrup that processes is put on shaper according to stirrup diameter, see on the straight length of the stirrup that processes not identical and overlap with straight length on the mould, if straight length and the straight appearance of mould with or flat segments as if not overlapping, illustrate that this stirrup adds the straight length and the angle of bend in man-hour and can not satisfy job specfication and designing requirement; Otherwise, satisfy job specfication and designing requirement.
