Abstract
The invention relates to an uplift resistance test device for a pre-stressed pipe pile, comprising a pile cylinder, an upper pulling beam, a lower pulling beam, a main beam and a lifting jack; the upper pulling beam and the lower pulling beam are fixedly connected by a tension rod; the lower pulling beam is fixedly connected with the beam cylinder; the upper pulling beam and the lower pulling beam are installed at two sides of the main beam; the lifting jack is installed between the upper pulling beam and the lower pulling beam; and the main beam is connected with the ground by a buttress. The uplift resistance test device for the pre-stressed pipe pile, provided by the invention, eliminates defects existed in the background art; the pile cylinder is connected with an end plate by a flange, so that the pre-stressed pipe pile is stressed stably and has no occurrence of eccentric situations; and the uplift resistance test device for the pre-stressed pipe pile has a simple structure, shortened construction period and wide application range, and is firm to connect.
Description
Technical field
The present invention relates to a kind of testing arrangement for building, relate in particular to a kind of pile for prestressed pipe resistance to plucking experimental rig.
Background technology
In the prior art, the resistance to plucking test of pile for prestressed pipe is generally tested by several forms, 1, Type of Welding, with pile crown end plate and draw ring welding, by jack the mode of roof pressure draw ring is tested the uplift resistance of pile tube then, need weld the stake end plate, and not prison welding is leaned on, discontinuity, eccentric easily; In addition, by the form of poured concrete in pile body, this shortcoming is that curing time is longer, the effort of taking a lot of work, and pile body inside occupies dust easily, and behind the fluid concrete, concrete is connected unstable with pile body, easily pour mass is extracted.
Summary of the invention
The technical problem to be solved in the present invention is: the reliable pile for prestressed pipe resistance to plucking of a kind of connection experimental rig is provided.
In order to overcome the defective that exists in the background technology, the technical solution adopted for the present invention to solve the technical problems is: a kind of pile for prestressed pipe resistance to plucking experimental rig, comprise stake tube, last straining beam, following straining beam, girder and jack, the described straining beam of going up is fixedlyed connected by pull bar with following straining beam, following straining beam is fixedlyed connected with the stake tube, last straining beam and following straining beam are positioned at the both sides of girder, are provided with jack between last straining beam and the girder, and girder is connected with ground by buttress.
According to another embodiment of the invention, pile for prestressed pipe resistance to plucking experimental rig comprises that further described stake tube is provided with flange, fixedlys connected with the pile for prestressed pipe end plate by flange.
According to another embodiment of the invention, pile for prestressed pipe resistance to plucking experimental rig comprises that further described stake tube and pile for prestressed pipe are by being threaded.
According to another embodiment of the invention, pile for prestressed pipe resistance to plucking experimental rig further comprises between described stake tube and the flange and is welded with reinforcing rib.
According to another embodiment of the invention, pile for prestressed pipe resistance to plucking experimental rig comprises that further described stake tube is solid cylinder or hollow cylinder.
The invention solves the defective that exists in the background technology, stake tube is connected by flange with end plate, makes the pile for prestressed pipe stability under loading, and phenomenon produces without acceptance of persons, and is simple in structure, be connected firmly, and the duration shortening, applied widely.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Wherein: 1, stake tube, 2, go up straining beam, 3, straining beam down, 4, girder, 5, jack, 6, buttress, 7, flange, 8, pile tube, 9, pull bar, 10, dial gage.
The specific embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of pile for prestressed pipe 8 resistance to plucking experimental rigs, comprise stake tube 1, last straining beam 2, following straining beam 3, girder 4 and jack 5, the described straining beam 2 of going up is fixedlyed connected by pull bar 9 with following straining beam 3, following straining beam 3 is fixedlyed connected with stake tube 1, last straining beam 2 and following straining beam 3 are positioned at the both sides of girder 4, are provided with jack 5 between last straining beam 2 and the girder 4, and girder 4 is connected with ground by buttress 6.Preferably be provided with flange 7 on the described stake tube 1, fixedly connected with pile for prestressed pipe 8 end plates 9, make pile for prestressed pipe 8 stability under loading by flange 7.Wherein, stake tube 1 and pile for prestressed pipe 8 are convenient to adjusting by being threaded, and prevent off-centre.Wherein, be connected with dial gage 10 on the flange 7 of stake tube 1.
In addition, be welded with reinforcing rib between stake tube 1 and the flange 7, because the uplift resistance of pile tube 8 is relatively large, the uplift resistance of general pile tube 8 has about 140 tons, adopts above-mentioned the setting to guarantee that flange 7 is not drawn bad.
King-pile tube 1 of the present invention is solid cylinder or hollow cylinder.
The invention process process is as follows:
At first start hydraulic jack 5, be used for straining beam 2 by girder 4 outbreaks, then, last straining beam 2 pullings are straining beam 3 down, following straining beam 3 promotes to pull out on the stake tube 1, thereby promote to pull out on the pile for prestressed pipe 8, adjust hydraulic jack 5 pressure, be controlled at about 140 tons, testing time was generally 40 hours～50 hours, at last, by dial gage 10 check pile for prestressed pipe 8 on pull out distance whether in the resonable degree scope, and implement this experiment and finish.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the manual, must determine its technical scope according to the claim scope.
