Description
Technical field
The invention belongs to pullout tests technical field, more particularly to a kind of foundation anchor pulling resistance testing device.
Background technology
High building annex part can produce the situation of pulling out, work as soil by the case of descending water or horizontal loading larger higher
When body frictional force is insufficiently resistant to uplift force, bottom plate can produce destruction, and then influence the safety of superstructure, therefore be needed in designing
Check the anti-pulling capacity of now foundation anchor.
At present, it is all that the methods of simulating load multistage loadings is tried that pullout tests detection for foundation anchor is main
Test, comparatively, the design withdrawal resistance bearing value of foundation anchor is smaller（200kN~500kN）, but arrange the number of foundation anchor
Amount is more, and it is that comparison is high that it, which inspects frequency by random samples, therefore the consumption plenty of time need to be spent to go to complete to test, it is corresponding used in set
Standby assembling will also spend the consumption plenty of time.And traditional reinforcing bar fixed form is to use to be welded and fixed, and is wasted time and energy.Therefore, change
Entering foundation anchor pulling resistance testing device can preferably complete to test, and save the time of assembling equipment, greatly improve operating efficiency.
The content of the invention
It is easy to install quick it is an object of the invention to provide a kind of foundation anchor pulling resistance testing device, save people
Power material resources.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of foundation anchor pulling resistance testing device, including base supporting plate, the centre-hole jack being arranged in base supporting plate,
And the lockset for being used to lock reinforcing bar at the top of centre-hole jack is arranged on, the base supporting plate centre is provided with and supplies steel
The circular hole that muscle passes through.
Further, the lockset includes lock collar and the anchor for fixed steel bars.
Further, the lock collar is the thick rectangular steel plates of 20 ~ 40mm, which is provided with it is multiple passed through for reinforcing bar it is logical
Hole.
Further, the anchor external diameter is more than the diameter of through hole in lock collar.
Further, it is additionally provided with the nut matched with screw thread steel above the anchor.
Further, the base supporting plate is the thick rectangular configurations of 20 ~ 40mm, and four angles are equipped with the first hasp
Ring.
Further, two the second hasp rings are arranged with the centre-hole jack lateral wall.
Further, the Circularhole diameter is less than centre-hole jack external diameter.
Compared with prior art, the invention has the advantages that：
A kind of foundation anchor pulling resistance testing device of the present invention, design science is reasonable, easy to use, very heavy by punching
Top is used cooperatively with lockset so that whole experimental rig installation and removal become simple and convenient, are greatly saved manpower thing
Power, there is extremely strong practicality.
Brief description of the drawings
Fig. 1 is the schematic diagram of a preferred embodiment of the present invention.
Fig. 2 is the schematic diagram of base supporting plate.
Fig. 3 is the schematic diagram of lock collar.
Embodiment
A kind of foundation anchor pulling resistance testing device of the present invention is made below in conjunction with specific embodiment and accompanying drawing further
It is described in detail.
As shown in Figure 1, Figure 2 and Figure 3, in a preferred embodiment, a kind of foundation anchor pulling resistance testing device of the invention, bag
Base supporting plate 1 is included, the centre-hole jack 2 being arranged in base supporting plate 1, and it is arranged on the top of centre-hole jack 2
Be used for lock the lockset 3 of reinforcing bar 4, the centre of base supporting plate 1 is provided with the circular hole 12 passed through for reinforcing bar 4.Wherein, circle
The diameter of hole 12 is less than the external diameter of centre-hole jack 2, preferably consistent with the internal diameter of centre-hole jack 2, so as to ensure Stability Analysis of Structures
And uniform force.Reinforcing bar 4, will using lockset 3 through the circular hole 12 in base supporting plate 1 and then through centre-hole jack 2
Reinforcing bar 4 is locked, so as to carry out pullout tests.
The lockset 3 includes lock collar 31 and the anchor 32 for fixed steel bars 4；Wherein, lock collar 31 is 30mm thick
Rectangular steel plates, it which is provided with multiple through holes 311 passed through for reinforcing bar 4；In the present embodiment, 3 are provided with lock collar 31 and is led to
Hole 311, and be in isosceles triangle branch in the centre of lock collar 31, the quantity of through hole 311 and position are depending on specific test objective；
The external diameter of anchor 32 is more than the diameter of through hole 311 in lock collar 31.In order to further reinforce locking effect, on anchor 32
Side is additionally provided with the nut 33 matched with the screw thread of reinforcing bar 4.In the present embodiment, from thick 30mm rectangular steel plates cost and performance ratio most
It is good, it can reach constructed effect from the thick rectangular steel plates of 20 ~ 40mm in addition, the length of side of rectangular steel plates cannot be less than punching
The external diameter of formula jack 2, ensure that stress safety and equipment are stable.
In order to ensure that equipment is reliable and stable, and convenient installation, dismounting and transport, the base supporting plate 1 are also selected
Rectangular configuration steel plate thick 30mm, and the first hasp ring 11 is equipped with four angles of base supporting plate 1, pass through the first hasp ring
11 facilitate the movement of base supporting plate 1.It is optimal from rectangular steel plates cost and performance ratio thick 30mm in the present embodiment, this
The outer rectangular steel plates thick from 20 ~ 40mm can reach constructed effect, and the length of side of base supporting plate 1 should be much larger than punching
The external diameter of formula jack 2, ensure that stress safety and equipment are stable.
Two the second hasp rings 21 are arranged with the lateral wall of centre-hole jack 2, can be very convenient using the latch closure
Mobile centre-hole jack 2, greatly improve installation and removal efficiency, be also convenient for transport.
In addition, steel plate used by with upper bed-plate supporting plate 1 and lock collar 31, is that cold-rolling process is made, its intensity and hard
Degree is high, ensures that equipment is safe and reliable.
Although description of this invention combination embodiments above is carried out, those skilled in the art
Member can carry out many replacements, modifications and variations according to above-mentioned content, be obvious.Therefore, it is all it is such substitute,
Improve and change is included in the spirit and scope of appended claims.
