Abstract

A special inspection tool for stirrup hooks is in a symmetrical plate ruler shape, the surface of the plate ruler is flat and provided with two long edges, an angle a formed by the two long edges is in a circular arc shape, the angle is 45 degrees, the radius of the circular arc is matched with the radius of a bending circular arc of the stirrup hook, and the two long edges are tangent sections of the circular arc; the length of two long edges is equal to the length of the stirrup hook, and a short edge of the plate ruler is arranged between the end parts of the two long edges. The tool is made of a multi-layer plate or a three-layer plate or made of a hard iron sheet. Simple light, put the instrument in the stirrup, observe whether the stirrup agrees with it, can judge whether angle of buckling and straight length satisfy the requirement, can inspect the angle of buckling of stirrup crotch and the straight length of stirrup at any time, guarantee the processing and the construction quality of reinforcing bar stirrup crotch.

Description

The special-purpose checking tool of stirrup hook

Technical field

The utility model relates to a kind of checking tool of stirrup hook of civil engineering structure inspection of construction instrument, particularly a kind of reinforced bar engineering.

Background technology

At present, in the engineering construction process, labor service is the valuable source of building enterprise; And along with the continuous increase of construction project quantity in all parts of the country; The labor service resource gap is also in continuous expansion, thereby causes labour's construction quality to descend, and the reinforcing bar crudy also descends to some extent simultaneously.

In Structural Engineering, stirrup is to be used for satisfying the oblique section shearing strength, and connects and to be drawn main reinforcement and compressive region concrete to make its co-operation opposing shearing, simultaneously the fixing position of main reinforcement and make the reinforcing bar of various reinforcing bars formation frameworks of steel reinforcement in the beam.Therefore, in structure construction, the construction quality of stirrup is very crucial.

To the stirrup quality in the structure construction, often find at the reinforcing bar processing space: the stirrup of machine-shaping exists bending angle not reach mass defects such as requirement, stirrup flat segments length be not enough.

The utility model content

The utility model provides a kind of instrument that is used for the inspection of stirrup hook specialty, its objective is in the reinforcing bar process, checks the crotch angle of stirrup and the flat segments length of stirrup hook at any time, improves the construction quality of structure construction stage stirrup.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

The instrument of stirrup hook specialty inspection; This instrument is the board foot shape of symmetry, and the surfacing of said board foot comprises two long limits; Article two, folded angle, long limit is a circular arc; Its angle is 45 °, and the crooked arc radius of its arc radius and stirrup hook adapts, and two long limits are the tangent section of circular arc; Article two, the equal in length of the length on long limit and stirrup hook is the minor face of board foot between the end on two long limits.

The minor face of said board foot is a straight flange.

The minor face minor face of said board foot is a flanging or claims two isometric minor faces; Article two, minor face is perpendicular with two adjacent long limits respectively; Article two, the minor face angle is the obtuse angle, and angle is described two the long limit angles of summit to the circular arc circle center line connecting five equilibrium at 135 ° of these obtuse angles, two minor face angles.

Said stirrup hook specialty checking tool is made with multilayer board or three-ply board, maybe can use the hard iron sheet to make.

The utility model is simply light, according to the different size of stirrup diameter, can check the flat segments length of the bending angle and the stirrup of stirrup hook at any time.

The utility model can be checked the crudy of reinforcing bar backstage stirrup hook at any time at the reinforcement construction scene, and the quality of stirrup construction behind the reinforcing bar binding.Guarantee the processing and the construction quality of steel wire binding bar crotch.

The utility model can reach the good result of rapid raising stirrup crudy.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further detailed explanation.

Fig. 1 is the utility model structural representation.

Fig. 3 is the application synoptic diagram of the utility model inspection Φ 8 stirrup hooks.

The long limit of Reference numeral: L-, H-minor face, M-circular arc, R-arc radius, the o-circular arc center of circle, a-two long limit angles, b-two minor face angles.

Embodiment

Embodiment one is referring to shown in Figure 1, and the instrument that the stirrup hook specialty is checked, this instrument are the board foot shape of symmetry; The surfacing of said board foot; Comprise two long limit L, two folded angle a in long limit are circular arc, and its angle is 45 °; The crooked arc radius of its arc radius R and stirrup hook adapts, and two long limits are the tangent section of circular arc M; Article two, the equal in length of the length of long limit L and stirrup hook is the minor face H of board foot between the end of two long limit L; The minor face H of said board foot is a straight flange; The minor face minor face H of said board foot is a flanging or claims two isometric minor faces; Article two, minor face is perpendicular with two adjacent long limits respectively; Article two, minor face angle b is the obtuse angle, and angle is described two the long limit angle a of summit to the circular arc circle center line connecting five equilibrium at 135 ° of these obtuse angles, two minor face angle b.

Embodiment two is referring to shown in Figure 2, the inspection method of said stirrup hook specialty checking tool, and step is following:

Step 1: selecting arc radius according to survey stirrup specification is 5 centimetres instrument;

Step 2: checking tool is put in the stirrup structure compatible degree of viewing tool and stirrup;

Step 3:, judge whether stirrup is up to specification according to agreeing with degree.

Embodiment three is referring to shown in Figure 3, and different with embodiment two is that said instrument arc radius is 4 centimetres.
