Abstract
The utility model belongs to the construction machinery field relates to foundation pile resistance to plucking static test's connecting device, including a base plate, there are two bell mouths side by side on the base plate, the conical surface opposite direction of two bell mouths is used for passing respectively and waits two reinforcing bars connecting to be provided with matched with toper voussoir with it in the inboard of bell mouth, and a plurality of toper voussoirs are lighter than the bar diameter to the hole that closes formation. The utility model discloses a connector is put into to the reinforcing bar that the advantage embodies on the reinforcing bar of test pile and jack entablature, with the fixed back of supporting toper voussoir, can test, need not the welding, saves time, has improved efficiency. Avoided leading to experiment failure, reliable and simple because of the splice fracture.
Description
Technical field
This utility model belongs to building machinery field, is related to a kind of attachment means for foundation pile resistance to plucking static test.
Background technology
Static load pullout tests are the methods using the actual operating conditions close to vertically pulling-resistant stake, and multistage loadings, reading are remembered
Settling amount, determines the detection method of vertical ultimate uplift resistance of single pile according to load～displacement curve feature.It is very heavy during test
Top work, its piston rise, and power upwards acts on foundation pile by the reinforcing bar of welding, and downward act on supporting by girder
Power on pier (stake) forms the balance of power step by step.The main deficiency of existing construction method shows：Experiment is stated in realization
During, it usually needs the reinforcing bar being connected by the reinforcing bar being connected with jack and with test pile is attached by welding manner, weldering
The workload for connecing is big, and the time is long, and welding quality has high demands, many because weld fracture causes test failure in many cases.
The content of the invention
Main purpose of the present utility model is：By the attachment means for foundation pile resistance to plucking static test, can be quick
Reinforcing bar on connection test pile, and it is solid and reliable, working performance is high.
In order to reach the above object, basic technical scheme of the present utility model is：For foundation pile resistance to plucking static test
Attachment means, including a substrate, have two bellmouths arranged side by side on substrate, the conical surface of two bellmouths is in opposite direction, for dividing
Two reinforcing bars that Chuan Guo be not to be connected, are provided with multiple circular cone wedges with matching on the inside of each bellmouth
Block, is the conical surface being engaged with bellmouth on the outside of taper voussoir, and inner side is the face of cylinder of part, multiple circular taper voussoirs
The endoporus being combined to form is less than bar diameter.
Used as the further improvement of the utility model, the quantity of the attachment means taper voussoir is 3 pieces or 4 pieces.
As the further improvement of the utility model, in the attachment means, on the inside of taper voussoir, anti-slip tank is provided with.
Advantage of the present utility model is embodied in：1. the reinforcing bar on the reinforcing bar of test pile and jack entablature is put into attachment means
In, it is after being fixed with supporting taper voussoir, you can tested, without the need for welding, time-consuming, improve efficiency.2. avoid
It is because weld fracture causes the failure of an experiment, simple, it is safe and reliable.
Description of the drawings
Fig. 1 is cross-sectional view of the present utility model；
Overlooking the structure diagrams of the Fig. 2 for picture.
Specific embodiment
A kind of attachment means for foundation pile resistance to plucking static test, including a substrate 3, have two cones arranged side by side on substrate 3
Shape hole 2, the conical surface of two bellmouths are in opposite direction, and for being each passed through to be connected two reinforcing bar 1, the aperture of bellmouth 2 is big
It is little to pass through reinforcing bar 1, the inner side of bellmouth 2 is provided with taper voussoir 4 with matching, the outside of taper voussoir 4 be with
The conical surface that bellmouth 2 is engaged, inner side are the faces of cylinder of part, and the endoporus that multiple taper voussoirs 4 are combined to form is straight less than reinforcing bar 1
Footpath.
A kind of attachment means for foundation pile resistance to plucking static test, the quantity of taper voussoir 4 is 3 pieces or 4 pieces.
A kind of attachment means for foundation pile resistance to plucking static test, the inner side of taper voussoir 4 arrange anti-slip tank.
Specific implementation process is such：The bellmouth 2 that will be pierced on the left of substrate 3 with the reinforcing bar 1 that jack is connected,
Taper voussoir 4 is embedded between bellmouth 2 and reinforcing bar 1 centre that reinforcing bar 1 is fixed on bellmouth 2, the steel being connected with test pile
Muscle 1 is pierced in the right side bellmouth 2 of substrate 3, and taper voussoir 4 is embedded between bellmouth 2 and reinforcing bar 1, by jack
Pressurization carries out tensioning operation, and reinforcing bar 1 forms self-locking by the frictional force of taper voussoir, realizes quickly connecting for upper and lower two reinforcing bars 1
Connect, and safe and reliable, high working efficiency, it is easy to accomplish.
