Embodiment
Just attached drawing in conjunction with the embodiments below, is described in further detail the embodiment of the present invention, so that of the invention
Technical solution is more readily understood, grasps, so as to make relatively sharp define to protection scope of the present invention.
Designer of the present invention needs many deficiencies of Site Detection for existing crab-bolt class material tension shearing strength, is dependent on
In long-term producing line experience, a kind of experimental rig of crab-bolt tension shearing strength is creatively proposed, is widely used in each
The crab-bolt of specification carries out non-at-scene indoor detection.The experimental rig is mainly by selecting supporting stretching clamp, when foundation designs
It is required that substrate intensity and crab-bolt anchorage depth, by laboratory test to detect the suitability of crab-bolt and concrete and most
Big value of thrust and shear strength etc..
From the point of view of technological overview, the innovation structure of the experimental rig of this kind of crab-bolt tension shearing strength is as shown in Figure 1, the examination
Experiment device several core components compositions including base 1, hanging deck 2, clamping plate 3, stretching clamp, screw rod 5 and hollow drawing instrument 6.From
Visible CONSTRUCTED SPECIFICATION is illustrated, which is arranged in above base in the horizontal plane of level altitude by vertical guide rod 11, i.e., high
Degree meets the enough lifting activity spaces of clamping plate.And clamping plate 3 by the guide spiro rod 4 set by corner be bolted to 2 bottom side of hanging deck and
Lift adjustable, screw rod 5 is connected at the top of the bottom and stretching clamp of hanging deck 2 and screw rod 2 the fixed, bottom of stretching clamp that is screwed on
It is screwed on fixation with crab-bolt 81, the epimere that screw rod 5 is located at hanging deck top side is connected to hollow drawing instrument 6 and by 9 positioning locking of nut, should
Crab-bolt 81 links with stretching clamp, screw rod 5 and is departed from concrete in hollow drawing instrument 6 by traction force（Need and coagulation in actual measurement
Soil breaks through one, loosening property change in displacement trend occurs）, thus then the tension of the reading association crab-bolt of hollow drawing instrument resists
Cut intensity（Different required results is obtained according to the technicality of test method）.
From the point of view of the structure further refined, it is above-mentioned refer to clamping plate lifting it is adjustable, it is intended to one can be conceded and wait to try
The suitable space that material passes in and out base and dropping place is tested is tested, and is locked the concrete parts of material to be tested by pressing downwards
Gu.From the point of view of concrete structure, above-mentioned 4 surface of every guide spiro rod is equipped with screw thread and the bottom bearing of guide spiro rod is connected on
Clamping plate 3, guide spiro rod 4 link with the one of clamping plate 3 and are diametrically freely rotated in the axial direction；The guide spiro rod 4 from bottom with
On main paragraph be connected with 2 screw of hanging deck, the demand that clamping plate 3 lifts with guide spiro rod 4 can be realized based on screw motion principle；
And the top of the guide spiro rod 4 is set to the matching rotating drive division of external tool（Can be outer hex nut, interior hexagon spiral shell
Cap etc.）；And four guide spiro rods 4 can be lifted under exterior tool drives with synchronous rotation, and connect by outside and set electronic work
Have each guide spiro rod of linkage and drive and realize synchronous rotary（It is not shown）, so that clamping plate can realize the parallel lifting of opposite base.
It round rotation can certainly lift one by one, by manually adjusting guide spiro rod and repeating query one by one, reach the height needed for clamping plate.
As the demand further automated, the connection structure of the clamping plate and guide spiro rod can also be：The guide spiro rod
Bottom be fixed in clamping plate, and the top activity of guide spiro rod is connected in hanging deck, is equipped between hanging deck and clamping plate vertically to driving
The jacking cylinder of clamping plate lifting, and jacking cylinder is mutually avoided with screw rod.Jacking cylinder is so manipulated by manual or automaticization, it is real
The automation lifting of existing clamping plate, improved efficiency are notable.
Above-mentioned hanging deck 2 is equipped with the first perforation 21 in the drop shadow spread of corresponding clamping plate 3, and screw rod 5 is optionally worn and connect
In the first perforation 21 and penetrate clamping plate 3 and connect with stretching clamp.Above-mentioned hanging deck 2 is externally provided with the in the drop shadow spread of corresponding clamping plate 3
Two perforation 22, and screw rod 5 is optionally connected to the second perforation 22 and connects with stretching clamp.It is of course also possible to two are worn
Hole is arranged on hanging deck 2 in the lump, embodiment as depicted in figs. 1 and 2.
In addition, above-mentioned 1 one side of base, which is equipped with, transports the feeding slide 12 that material to be tested enters base 1, the feeding slide 12
For passive manpower is driving or electric self-driven type.Diagram is as it can be seen that the feeding slide is the row's quilt set along material transmission direction
Dynamic live roller, so material to be tested can be on it by easily man-drivens, or pass through the automation push-and-pull of exterior arrangement
Device carries out automatic operating.Obviously can be to avoid being difficult to the material to be tested that promotes such weight in conventional planar, or need
Manpower is transported to the situation of base.
Illustrate in embodiment, which has ability of both stretching resistance test and shear strength test concurrently, and
Operation switching is easy to implement.It is specific as follows：Shown in Fig. 1 be this experimental rig carry out crab-bolt stretching resistance test implementation state show
Meaning.Wherein the used stretching clamp 71 with screw rod 5 is detachable connects, the bottom of stretching clamp 71 has corresponding various anchors
Any internal diameter specification that bolt connects, and the top of the stretching clamp of various internal diameter specifications has the internal diameter of corresponding screw rod uniformity
Specification.That is, the stretching clamp as the upper and lower linking, has a variety of matched bottom inner diameters for different crab-bolt specifications
Specification, to meet to be connected various crab-bolts when being tested.The experiment process is：Material to be tested is laterally sent into base and clamping plate
Between the test space in, crab-bolt is upward at this time；Sequentially it is connected screw rod 5, stretching clamp 71 and crab-bolt 81, and is worn above hanging deck 2
Connect hollow drawing instrument 6（Zero pressure state）, then with nut lock fixed bit.Then put down clamping plate 3 and pressing is implemented to concrete material.Most
Pressurize afterwards to hollow drawing instrument 6, make it drive screw rod 5 to transmit upward pulling capacity to crab-bolt.And loosened when crab-bolt occurs
The reading of the hollow drawing instrument of moment is the maximum stretching resistance of the crab-bolt.
Shown in Fig. 2 is the implementation state signal that this experimental rig carries out anchor bolt anti-shearing-force test.Wherein this is used
Stretching clamp 72 with screw rod 5 is detachable connects, 72 side walls of stretching clamp are equipped with interior swaged down-the-hole, and down-the-hole has and corresponds to
Any internal diameter specification of various crab-bolt sockets, the top of each stretching clamp have the internal diameter specification of corresponding screw rod uniformity.
That is the stretching clamp as the upper and lower linking, has a variety of matched down-the-hole internal diameter specifications for different crab-bolt specifications, with
Satisfaction is socketed various crab-bolts when being tested.The experiment process is：Material to be tested is laterally sent into base and clamping plate after being reversed
Between the test space in, crab-bolt is towards the right side at this time；Sequentially it is connected screw rod 5, stretching clamp 71 and crab-bolt 81, and is worn above hanging deck 2
Connect hollow drawing instrument 6（Zero pressure state）, then with nut lock fixed bit.Then put down clamping plate 3 and pressing is implemented to concrete material.Most
Pressurize afterwards to hollow drawing instrument 6, make it drive screw rod 5 to transmit lateral shearing force to crab-bolt.And loosened when crab-bolt occurs
