Abstract
The utility model discloses a kind of fixture of pile for prestressed pipe resistance to plucking test, belongs in the test of pile foundation engineering vertical load, for test provides counter-force, loads connected system field of tool.It comprises 1, counter-force lasso trick, 2, anchor ear fixture, 3, wedge shape intermediate plate, and 4 pile for prestressed pipe (Fig. 1).Beneficial effect be by ring-type counter-force lariat loop after adding stretching force to extruding, increase self-locking system self-lock force between anchor ear fixture and stake, realize pile for prestressed pipe and be connected with fixture is reliable and stable.
Description
Technical field
The utility model relates to a kind of self-locking clamp of pile for prestressed pipe vertically pulling-resistant test counterforce device, mainly refers to the jockey of pile for prestressed pipe and reaction beam.
Background technology
In existing prestressed concrete pipe pile resistance to plucking test, the method for attachment of pile body and jack has three kinds of methods.The one, fill out core method, it builds slightly expanded concrete and in concrete, inserts some reinforcing bars in the pipe hole of pile tube, after concrete curing reaches design strength, by welding method, reinforcing bar or reinforcing pull rod is joined together to form to counter-force connected system.The 2nd, welding, it is by welding method, pile tube termination steel plate and transition steel plate or transition steel case to be linked together, form counter-force connected system, the 3rd, bolted-on connection, it is by Manual punching on prestressed pipe pile lining, the steel plate in stake outside is connected with pile tube by bolt, forms counter-force connected system.The utility model is mainly applicable to test pile and reaction beam quick links, forms the counter-force link system of self-locking, below the weak point of existing test pile and reaction beam link method for main narration.
The shortcoming of 1, filling out core method is must concreting and welding, therefore the effort curing time of taking a lot of work is long, counter force system quality of connection is also difficult for assurance;
2, the shortcoming of welding is that pile tube termination steel plate easily pulls, and is not suitable for the test of the pile for prestressed pipe anti-pulling capacity that uplift resistance is larger;
3, the shortcoming of bolted-on connection is to punch on pile for prestressed pipe tube wall, causes the destruction of pile body, affects the load-carrying properties in pile tube later stage, and because Brittleness of Concrete is difficult to accurately form channel diameter, outside steel plate easily produces slippage, each bolt strained inequality.
Summary of the invention:
For the problem of above-mentioned existence, the utility model provides a kind of self-locking jig, realizes test pile tube be connected fast with anchor ear fixture by self-locking, automatically terminates the connection of test pile tube and anchor ear fixture after test off-load simultaneously.
The utility model solves the technical scheme that its technical problem adopts: a kind of fixture of pile for prestressed pipe resistance to plucking test, it comprises counter-force lasso trick (1), anchor ear fixture (2), wedge shape intermediate plate (3), pile for prestressed pipe (4).It is characterized in that: counter-force lariat loop is embraced hoop clip tool, two anchor ear fixtures are encircled pile for prestressed pipe, and two anchor ear fixtures are with bolts, and wedge shape intermediate plate anchor ear fixture embeds between pile for prestressed pipe.
Anchor ear fixture by two semicircle arcuations is embraced folder pile for prestressed pipe, adopt wedge shape Double-sided indented intermediate plate to embed between fixture and pile tube, by bolt, anchor ear fixture, wedge shape intermediate plate and pile for prestressed pipe are clamped in advance, anchor ear fixture is arranged on the position of pile foundation appointment.When applying trial load, outside anchor ear fixture, counter-force lasso trick is installed, the hoop extruding force that counter-force lasso trick after tension forms, make anchor ear fixture produce normal direction extruding force to intermediate plate, intermediate plate produces normal direction extruding force to pile for prestressed pipe, and anchor ear fixture, intermediate plate and pile for prestressed pipe three form self-locking system.Its beneficial effect is to realize pile for prestressed pipe to be connected with fixture is stable, is self-locking state.
Accompanying drawing explanation
Fig. 1 is wedge shape intermediate plate figure.
Fig. 2 is pile for prestressed pipe resistance to plucking anchor ear grip device.
Wherein the toponym of each digital representative and effect thereof are listed in the table below.
The specific embodiment
Anchor ear holder part of the present utility model and wedge shape intermediate plate, the material of use is steel.It is mainly comprised of four parts: 1 counter-force lasso trick, 2 anchor ear fixtures, 3 wedge shape intermediate plates, 4 pile for prestressed pipe.The specific embodiment:
A makes fixture and pile for prestressed pipe extruding wedge shape intermediate plate (Fig. 1) by bolt, and stationary fixture is in installation site;
B installs counter-force lasso trick, applies trial load, causes counter-force lasso trick tension (Fig. 2).Counter-force lasso trick is encircled fixture wedge shape intermediate plate is produced to extruding force, along with counter-force lasso trick pulling force increases, pile for prestressed pipe and anchor ear fixture is increased to wedge shape intermediate plate extruding force, produces self-locking effect between three, causes anchor ear fixture not produce vertical slippage;
C tests off-load, and after counter-force lasso trick pulling force is zero, self-locking clamp automatically terminates self-locking effect.
Claims (1)
1. the fixture that pile for prestressed pipe resistance to plucking is tested, it comprises counter-force lasso trick (1), anchor ear fixture (2), wedge shape intermediate plate (3), pile for prestressed pipe (4).It is characterized in that: counter-force lariat loop is embraced hoop clip tool, two anchor ear fixtures are encircled pile for prestressed pipe, and two anchor ear fixtures are with bolts, and wedge shape intermediate plate anchor ear fixture embeds between pile for prestressed pipe.
