Description
Technical field
The utility model belongs to field of mechanical technique, is specifically related to a kind of welded steel fabric solder joint shear test anchor clamps.
Background technology
In the construction project xoncrete structure, welded steel fabric and welded framework often adopt resistance spot welding to make, and for guaranteeing construction quality, carry out the test of anti-shear performance to the cross-coupled solder joint of reinforcing bar, and this just needs to be equipped with the shear test anchor clamps.At present the ordinary test method is, with two reinforcing bars of solder joint place right-angled intersection, one as horizontal bar, be fixed (blocking), and the vertical muscle of conduct bears pulling force, makes solder joint be subjected to shear stress, and is afterburning gradually, until cutting off, measures the peak load when destroying.Standard GB/T1499.3-2002 and industry standard JGJ78-86, JGJ18-96 are that transverse steel is suitably fixing, and reduces it as far as possible and influence by bending to the basic demand of shear test; Longitudinal reinforcement (tension reinforcement) free end can in axial direction slide; Its axis and afterburning dead in line.These standards have also been introduced several anchor clamps, and they must be used with a suspension bracket, are hung by the clamping of testing machine upper jaw, open the baffle plate of circular hole (breach) in the middle of the lower end has, and anchor clamps can be blocked, and longitudinal reinforcement stretch out from circular hole, by lower jaw clamping tension.No matter adopt which kind of form, these anchor clamps all can only adopt the tension mode to test.Their making is generally comparatively complicated, and installing and operating also has inconvenience.After the vertical muscle diameter of tension changes, can not guarantee the afterburning axis axis by lacing wire fully.And transverse steel influence by bending arranged.
Summary of the invention
The purpose of this utility model is to propose a kind of simple in structure, the welded steel fabric solder joint shear test anchor clamps of energy tension, pressure test.
The welded steel fabric solder joint shear test anchor clamps that the utility model proposes, form by the V-shaped groove on anchor clamps 4 and the anchor clamps 7, U-lag 8, (as depicted in figs. 1 and 2), anchor clamps 4 are a cube piece, and there is V-shaped groove 7 position, the inclined to one side axis of its end face, at the adjacent surface that is parallel to V-shaped groove 7 U-lag 8 is arranged, U-lag 8 bottom surfaces are the face of cylinder, the axial plane of symmetry of U-lag 8 and V-shaped groove 7 vertical symmetry, two grooves join and cross, and the bottom line of the axial plane of symmetry of V-shaped groove 7 and U-lag 8 is at a distance of certain distance.
In the utility model, when adopting the tension mode, anchor clamps 4 are positioned at suspension bracket baffle plate 5 tops, suspension bracket baffle plate 5 is held on the prominent along last of suspension bracket 2 biside plate inside lower end, the reinforcing bar solder joint is cut test specimen horizontal bar 6 and is positioned at V-shaped groove 7, the reinforcing bar solder joint is cut the vertical muscle 3 of test specimen and is positioned at U-lag 8, and the reinforcing bar solder joint is cut the vertical muscle 3 of test specimen and passed suspension bracket baffle plate 5 center holes.
In the utility model, when adopting the pressurized mode, the reinforcing bar solder joint is cut the vertical muscle 3 of test specimen and is positioned at U-lag 8, and the reinforcing bar solder joint is cut test specimen horizontal bar 6 and is positioned at V-shaped groove 7, and anchor clamps 4 are positioned at testing machine workbench center of effort position.
The utility model both can adopt the mode of tension, also can adopt the mode of pressurized to test.
Use of the present utility model is as follows:
When adopting the tension mode to test, as shown in Figure 3, the vertical muscle 3 of being cut test specimen is longer, and generally greater than 200mm, it is arranged in the U-lag of anchor clamps 4, and horizontal bar 6 rests on the V-shaped groove, and because of stressed downward, horizontal bar is promptly by V-shaped groove restriction secure fixation.To indulge the middle vacancy round mouth that muscle 3 passes suspension bracket plate washer 5 again, anchor clamps 4 are shelved on the baffle plate 5, baffle plate 5 shelves are on the prominent edge of suspension bracket 2 biside plate inside lower end.With testing machine upper jaw clamping suspension bracket pull handle 1, adjust anchor clamps 4 positions, make vertical muscle 3 axis by afterburning axis, with the vertical muscle of testing machine lower jaw clamping, can apply pulling force, the solder joint place is cut, afterburning to destroying, can measure the maximum shear load.
When adopting the pressurized mode to test, as shown in Figure 5, the vertical muscle 3 of being cut test specimen is shorter, above horizontal bar 6, only reserves the vertical muscle of about 10mm and gets final product, and long easy unstability is wanted smooth and axis normal and cut off mouth.The vertical muscle of about 25mm is reserved in horizontal bar 6 belows.During test, equally horizontal bar 6 is rested on the V-shaped groove 7, vertical muscle 3 is arranged in U-lag 8, will install the anchor clamps of test specimen, is placed on testing machine workbench center of effort position, the start lift platform, contact generation pressure with seaming chuck until test specimen, make solder joint be in the state cut, constantly afterburning, until destruction, can measure the maximum shear load.Obviously, adopting the pressurized mode, compared with the tension mode, needn't change the stretching clamp of testing machine, is the most simply and easily.
No matter be tension or pressurized tests, the utility model all can satisfy the basic demand of national standard to test fully.Horizontal bar is subjected to the restriction of V-shaped groove, and its solder joint opposite and osculatory V-shaped groove all contact with V-shaped groove, by support fully, so have not a particle of crooked the influence; Anchor clamps can move freely, so can conveniently adjust vertical muscle position, its axis are overlapped fully with afterburning axis.
The utility model is simple in structure, and is novel, and processing and fabricating is convenient.
