Abstract
The utility model discloses a clamp for testing strength of a steel bar head. An integrated base (12) and a raised part (11) form a structure of which the cross section is T-shaped, a through hole (131) of which the diameter is greater than that of a to-be-tested steel bar head is formed along the transverse direction of the raised part (11), a recessed part (132) matched with the to-be-tested steel bar head is formed on the base (12), and the through hole (131) and the recessed part (132) are communicated with each other and have the same center line. The clamp for testing strength of the steel bar head, provided by the utility model, has the advantage of being convenient, practical, and not easy to damage.
Description
Technical field
The utility model relates to the utility appliance of manufacturing for pile tube, relates in particular to a kind of fixture for test steel bar end intensity.
Background technology
In the pile tube manufacture process, reinforcing bar need to be fixed on end plate, then with the reinforcing bar tension, this reinforcing bar generally is stuck in pilot hole by the steel bar end of one end.As shown in Figure 3, this reinforcing bar 2 comprise columned reinforcing bar main body 21 and with steel bar end 22.Require the intensity of steel bar end to be not less than 90% of reinforcing bar main body intensity on engineering.If the intensity of steel bar end is undesirable, may causes reinforcing bar to be pulled from pilot hole, and then reduce the intensity of pile tube.
Current main employing triangle fixture, during due to experiment, pulling force is larger, and this fixture is easy to damage.
The utility model content
The technical problems to be solved in the utility model is, for the defects of prior art, provides a kind of simple in structure, non-damageable fixture for test steel bar end intensity.
For achieving the above object, the adoptable technical scheme of the utility model is:
A kind of fixture for test steel bar end intensity, it forms xsect by integrated base and lug boss and is T-shaped structure, laterally have diameter greater than the through hole of the diameter of reinforcing bar to be tested along this lug boss, have the depressed part that coordinates with steel bar end to be tested on this base, described through hole and depressed part are communicated with and have an identical center line.
An aspect according to the fixture for testing steel bar end intensity described in the utility model: the diameter of described through hole (131) is 10.75-10.9mm, 12.65-12.8mm, 7.05-7.3mm.
An aspect according to the fixture for testing steel bar end intensity described in the utility model: the longitudinal length of described base equals the longitudinal length of described lug boss, and this length is 8-12cm.
Fixture for test steel bar end intensity of the present utility model is not only simple in structure, easy to use, and very durable, not fragile.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in accompanying drawing:
Fig. 1 is the schematic diagram that the utility model is used to test the fixture of steel bar end intensity;
Fig. 2 is the transverse cross-sectional view that the utility model is used to test the fixture of steel bar end intensity;
Fig. 3 is the sectional view of reinforcing bar to be tested.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments only is used for explanation the utility model and is not used in restriction scope of the present utility model, after reading the utility model, those skilled in the art all falls within the application's claim limited range to the modification of the various equivalent form of values of the present utility model.
As depicted in figs. 1 and 2, the fixture 1 for test steel bar end intensity of the present utility model is comprised of integrated base 12 and lug boss 11, and the xsect of this fixture is T-shaped.Wherein laterally have diameter greater than the through hole 131 of the diameter of reinforcing bar to be tested along lug boss (11), have the depressed part 132 that coordinates with steel bar end to be tested on this base 12, through hole 131 and depressed part 132 are communicated with and have identical center line, form the through hole 13 of horizontal this fixture.When test, reinforcing bar shown in Figure 3 is passed this hole, both are placed on test board test.General, the diameter of reinforcing bar main body is 10.7mm, 12.6mm and 7mm, in the fixture of different embodiment, the diameter of through hole 131 is 10.75-10.9mm, 12.65-12.8mm, 7.05-7.3mm so.That is to say that the diameter of through hole is a bit larger tham the diameter of reinforcing bar main body, prevent that it from tilting in the hole, thereby guarantee the accuracy that reinforced steel bar strength is measured.In embodiment further preferably, the longitudinal length of base 12 equals the longitudinal length of lug boss 11, and this length is 8-12cm, so that this fixture is positioned on existing test board.In the situation that do not change the test board structure, only just can satisfy the demand of varying strength test by the size that changes this fixture.
Claims (3)
1. fixture that is used for test steel bar end intensity, it is characterized in that it forms xsect by integrated base (12) and lug boss (11) and is T-shaped structure, laterally have diameter greater than the through hole (131) of the diameter of reinforcing bar to be tested along this lug boss (11), have the depressed part (132) that coordinates with steel bar end to be tested on this base (12), described through hole (131) and depressed part (132) are communicated with and have an identical center line.
2. the fixture for test steel bar end intensity according to claim 1, it is characterized in that: the diameter of described through hole (131) is 10.75-10.9mm, 12.65-12.8mm, 7.05-7.3mm.
