Description
Technical field
The utility model 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 in the case of being subject to descend 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 foundation anchor at this time.
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 it is more, its inspect by random samples frequency be that comparison is high, therefore need to spend consumption the plenty of time go complete test, it is corresponding used in set
Standby assembling will also spend the consumption plenty of time.It is time-consuming and laborious and traditional reinforcing bar fixed form is to use to be welded and fixed.Therefore, change
It can preferably complete to test into foundation anchor pulling resistance testing device, save the time of assembling equipment, greatly improve work efficiency.
Utility model content
It is easy to install quick the purpose of this utility model is to provide a kind of foundation anchor pulling resistance testing device, section
About manpower and materials.
To achieve these goals, the utility model adopts the following technical solution：
A kind of foundation anchor pulling resistance testing device, including base support plate, the punching thousand being arranged in base support plate
Jin top, and the lockset for being used to lock reinforcing bar at the top of centre-hole jack is arranged on, the base support plate centre is set
There is the circular hole passed through for reinforcing bar.
Further, the lockset includes lock collar and the anchor for fixed steel bars.
Further, the lock collar be 20 ~ 40mm thickness rectangular steel plates, which is provided with it is multiple for reinforcing bar pass through lead to
Hole.
Further, the anchor outside diameter is more than the diameter of through hole in lock collar.
Further, it is additionally provided with and the matched nut of screw thread steel above the anchor.
Further, the base support plate is the rectangular configuration of 20 ~ 40mm thickness, 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 outside diameter.
Compared with prior art, the utility model has the following advantages that：
A kind of foundation anchor pulling resistance testing device of the utility model, design is scientific and reasonable, easy to use, by wearing
Core type jack and lockset are used cooperatively so that whole experimental rig installation and removal become simple and convenient, greatly save
Manpower and materials, have an extremely strong practicality.
Brief description of the drawings
Fig. 1 is the schematic diagram of one preferred embodiment of the utility model.
Fig. 2 is the schematic diagram of lock collar.
Embodiment
Below in conjunction with specific embodiment and attached drawing a kind of foundation anchor pulling resistance testing device of the utility model is made into
One step is described in detail.
As shown in Fig. 1 and Fig. 2, in a preferred embodiment, a kind of foundation anchor pulling resistance testing device of the utility model,
Including base support plate 1, the centre-hole jack 2 being arranged in base support plate 1, and be arranged on centre-hole jack 2 and push up
The lockset 3 for being used to lock reinforcing bar 4 in portion, 1 centre of base support plate is equipped with the circular hole passed through for reinforcing bar 4.Wherein, circle
Bore dia is less than 2 outside diameter of centre-hole jack, preferably consistent with 2 internal diameter of centre-hole jack, thus ensure stable structure and
Uniform force.Reinforcing bar 4 is through the circular hole in base support plate 1 and then through centre-hole jack 2, using lockset 3 by reinforcing bar
4 lockings, 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 thickness
Rectangular steel plates, 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 31 centre of lock collar, the quantity of through hole 311 and position are depending on specific test objective；
32 outside diameter of anchor 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 and the matched nut 33 of 4 screw thread of reinforcing bar.In the present embodiment, the rectangular steel plates cost and performance ratio of selection 30mm thickness are most
It is good, select the rectangular steel plates of 20 ~ 40mm thickness to reach constructed effect in addition, the length of side of rectangular steel plates cannot be less than punching
The outside diameter of formula jack 2, ensures that stress safety and equipment are stablized.
In order to ensure that equipment is reliable and stable, and convenient installation, dismounting and transport, the base support plate 1 are also selected
The rectangular configuration steel plate of 30mm thickness, and the first hasp ring 11 is equipped with four angles of base support plate 1, pass through the first hasp ring
11 facilitate the movement of base support plate 1.In the present embodiment, select the rectangular steel plates cost of 30mm thickness and performance ratio optimal, this
The rectangular steel plates of outer selection 20 ~ 40mm thickness can reach constructed effect, and the length of side of base support plate 1 should be much larger than punching
The outside diameter of formula jack 2, ensures that stress safety and equipment are stablized.
Two the second hasp rings 21 are arranged with 2 lateral wall of centre-hole jack, 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 support 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 the description combination embodiments above to the utility model carries out, it is familiar with the art
Personnel many replacements, modifications and variations can be carried out according to above-mentioned content, are obvious.Therefore, it is all such
Substitute, improve and change and be included in the spirit and scope of appended claims.
