Specific embodiment
It is of the invention to reach the technical means and efficacy that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Specific embodiment, structure, feature and its effect applied according to the present invention is described in detail such as in attached drawing and preferred embodiment
Afterwards.In the following description, what different " embodiment " or " embodiment " referred to is not necessarily the same embodiment.In addition, one or more
Special characteristic, structure or feature in a embodiment can be combined by any suitable form.
As depicted in figs. 1 and 2, a kind of building rod piece pullout tests grip device that one embodiment of the present of invention proposes
100 comprising pedestal 1 and clamping piece 2.Pedestal 1 has the pilot hole 10 through both ends.Clamping piece 2 has the folder through both ends
Hold hole 20.The aperture of holding holes 20 is adjustable.Clamping piece 2 is for being assemblied in the pilot hole 10 of pedestal 1, to be pressed from both sides by holding holes 20
Hold the building rod piece 200 across pilot hole 10.Wherein, pedestal 1 can opposing gripping members 2 along pilot hole 10 centerline direction activity
(i.e. arrow a direction in Fig. 2) makes to press from both sides to 2 applied force of clamping piece when pedestal 1 is mobile to side for opposing gripping members 2
The aperture for holding hole 20 becomes smaller, and builds rod piece 200 to clamp.
In the technical solution of above-mentioned offer, since holding holes 20 run through the both ends of clamping piece 2, thus even if building rod piece
200 such as foundation anchors or prestressing force prefabricated tubular pile fix at the construction field (site) by installation, and clamping piece 2 can also be set in construction rod
On part 200, and pass through the clamping building rod piece 200 of holding holes 20.It again because can be with when 1 opposing gripping members 2 of pedestal are mobile to side
To 2 applied force of clamping piece, the aperture of holding holes 20 is made to become smaller, clamping piece 2 clamps building rod piece 200 by holding holes 20.When right
When 1 further applied force of pedestal, since building rod piece 200 has installed fixation, pedestal 1 can drive clamping piece 2, and drawing is built together
Rod piece 200 is built, can be measured by amount of tension of the measuring device to building rod piece 200, it is existing in construction so as to realize
The pullout tests of building rod piece 200 are detected field.
To 2 applied force of clamping piece when in order to realize that aforementioned 1 opposing gripping members 2 of pedestal are mobile to side, make holding holes 20
The purpose that aperture becomes smaller, the present invention also provides the following technical solutions: as shown in Figures 2 and 3, clamping piece 2 above-mentioned can wrap
Include more than two split blocks 21, all have half bore on each split block 21, the half bore can for 1/2 hole, 1/3 hole, 1/4 hole or
1/5 etc..Wherein, the half bore cooperation on each split block 21 can surround holding holes 20 above-mentioned.At least one above-mentioned split block
21 are cooperated with the pilot hole 10 on pedestal 1 by inclined surface 102, which can be plane or curved surface etc..Pedestal 1 is used
The aperture of holding holes 20 is set to become smaller 21 applied force of split block by inclined surface 102 when opposing gripping members 2 are mobile to side,
Rod piece 200 is built to clamp.
In the examples described above, cooperated by the inclined surface 102 between pilot hole 10 on split block 21 and pedestal 1, when pedestal 1
When opposing gripping members 2 are mobile to side, the power towards 20 centerline direction of holding holes can be applied to split block 21, preferably
, the power of the application and the central axis of holding holes 20 keep split block 21 mobile to the centerline direction of holding holes 20, thus
So that the aperture of holding holes 20 is become smaller, and then plays the purpose for clamping building rod piece 200.
At one specifically using in example, as shown in Figures 2 and 3, pilot hole 10 above-mentioned can be taper type hole.Point
The face for cooperating with pilot hole 10 of body block 21 has the outer shape consistent with taper type hole.Wherein, taper type hole has
There is the effect for facilitating processing and installation.
Further, as shown in Figures 2 and 3, it can have screw thread on the hole wall in aforesaid clip hole 20, which mainly rises
To the effect for the frictional resistance for increasing 20 hole wall of holding holes, the clamping force of the clamping building rod piece 200 of holding holes 20 is improved.Certainly,
In order to increase the frictional resistance of 20 hole wall of holding holes, can also on the hole wall of holding holes 20 salient point or concave point etc., and pass through
The mode that screw thread is arranged increases the frictional resistance of 20 hole wall of holding holes, primarily to facilitating processing.
As shown in Fig. 2, pedestal 1 above-mentioned has opposite first end 11 and second end 12.Pilot hole 10 is from first end 11
It is through to second end 12, to form the first opening 101 in first end 11.Pedestal 1 is used for opposing gripping members 2 to 12 sidesway of second end
To 2 applied force of clamping piece when dynamic, the aperture of holding holes 20 is made to become smaller, builds rod piece 200 to clamp.Wherein, clamping piece 2 is used for
First opening 101 of the pedestal 1 to 12 side of second end non-bulging pilot hole 10 when mobile.
By above-mentioned setting, when external drive mechanism such as jack 4 is to 11 applied force of first end of pedestal 1, make seat
When 1 opposing gripping members 2 of body are mobile to 12 side of second end, since clamping piece 2 will not protrude the first opening 101 of pilot hole 10, from
And clamping piece 2 will not interfere the work of the external drive mechanism such as jack 4 of the first 101 sides of opening.
As shown in Figure 1, building rod piece pullout tests grip device 100 of the invention can also include push plate 3.Push plate 3 is covered
It is located in the first opening 101.Push plate 3 is equipped with the via hole passed through for building rod piece 200.When push plate 3 is used to be pushed by external force
Pedestal 1 is driven to move together.In this example, push plate 3 can be plate, and forced area is relatively large, facilitates external drive
Mechanism such as jack 4 pushes it.
Above-mentioned push plate 3 is fixedly connected with pedestal 1.Push plate 3 is equipped with handle, is carried with convenient working personnel or moves this
The building rod piece pullout tests grip device 100 of invention.
Further, as shown in Figure 1, building rod piece pullout tests grip device 100 of the invention can also include being used for
The driving mechanism that 1 opposing gripping members 2 of pedestal are mobile to side is driven, which may include jack 4, by very heavy
4 pairs of 3 applied forces of push plate are pushed up, push plate 3 is made to drive 1 opposing gripping members 2 of pedestal mobile to side, to resist to building rod piece 200
Pull out testing inspection.
What needs to be explained here is that: in the absence of conflict, those skilled in the art can according to the actual situation by
Relevant technical characteristic is combined with each other in above-mentioned each example, to reach corresponding technical effect, particularly for various combined situations
It will not repeat them here.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
