Abstract

The invention provides a jack-embedded type static testing girder for detecting the bearing capacity of a base pile, a foundation and the like, and aims at overcoming the shortages that the existing static testing girder is independent from a loading hydraulic jack, the jack and the girder are difficultly centered, most time is needed during mounting-, the overall mounting height is excessively high, and the safety and stability are poor. The jack-embedded type static testing girder is characterized in that a jack embedded cavity of which the bottom part is equipped with a hole is formed in the middle of a girder body (1); rib plates (2) are arranged at two ends of the embedded cavity, and a jack reaction plate (3) is arranged on the top part of the embedded cavity, and supporting rods (6) are arranged at two sides of the bottom part of the embedded cavity; the components above are all integrally welded; when assembling the girder, the jack (5) and the reaction plate (3) equipped with a connecting bolt hole are connected through a hanging bolt assembly (4); when in test, the hanging bolt assembly (4) can be completely released. The jack-embedded type static testing girder can be applied to static testing of an anchorage pile, a piling-up foundation pile and the foundation and the like.

Description

The embedded static loading test girder of jack
Technical field
The present invention relates to a kind of girder detected for foundation pile or bearing capacity of foundation soil, more particularly, the present invention relates to the embedded static loading test girder of a kind of jack.
Background technology
Static loading test girder is used for the foundation pile such as accumulation load method, anchored pile-testing method or bearing capacity of foundation soil detects.Existing static loading test girder is with to load hydraulic jack separate and install successively, dismantle.Jack and girder not easily centering, during installation fee, and make integral installation excessive height, security and stability is poor; Particularly for accumulation load method, the height of heap carrying platform is approximately the height sum of jack, girder, auxiliary girder etc., and platform is higher, and center of gravity is higher, more dangerous, simultaneously also higher for promoting the energy that mass consumes.
Summary of the invention
The object of the invention is to solve above-mentioned deficiency, provide a kind of installation, convenient disassembly, jack and girder need not centering and significantly can reduce Whole Equipment setting height(from bottom), the embedded static loading test girder of energy-conservation, safe jack specially.
To achieve these goals, the present invention adopts following technical scheme: the embedded static loading test girder of a kind of jack, described girder comprises beam body, the jack that centre position, its underpart is provided with bottom opening embeds chamber, embed two ends, chamber and have gusset, embedding top of chamber is jack reaction plate, jack suppending hole is opened at jack reaction plate and jack closure stud correspondence position, the embedded static loading test girder of jack is under the non-test states such as lifting and transport, by Hanging bolt assembly, beam body and jack are held together, and only Hanging bolt assembly need be totally released at the trial, embed the aperture having bottom chamber and supply jack free-extension, embed chamber two bottom sides and be provided with support bar, cavity configuration is embedded to the weakening of girder bearing capacity for compensating.Jack embeds chamber height should slightly larger than jack body height, so that jack " is not killed " when guarantee test starts.
Prior art broken through by the embedded static loading test girder of jack of the present invention, jack embedded girder inside, makes both be linked to be an organic whole, makes both without the need to special centering, lifts and transport very convenient; Because the complete bank of jack enters among girder, make integral installation height reduction about 300 ~ 500mm(jack height), while raising safety, also reduce the energy ezpenditure promoting preloading mass.
Accompanying drawing explanation
Fig. 1 is jack of the present invention embedded static loading test girder front view and sectional view.
Detailed description of the invention
As shown in Figure 1, the embedded static loading test girder of jack of the present invention, beam body 1 can adopt i beam or case beam, be provided with jack in the middle of it and embed chamber, embedding chamber is the hollow structure of bottom opening, and gusset 2 is established at its two ends, and reaction plate 3 is established at top, support bar 6 is established in both sides, and bottom is the aperture for jack free-extension.During girder assembling, first jack 5 is placed in level land, beam body 1 is being sling, make embedding chamber bottom port and jack about 5 centering, beam body 1 is fallen, then jack 5 and the reaction plate 3 having link bolt hole are coupled together with Hanging bolt assembly 4, the embedded static loading test girder of jack has been assembled.Under lifting and the non-test state such as transport, beam body 1 just connects into entirety with jack 5, girder and foundation pile pile crown or the disposable centering of ground load plate only need be made in testing site in place, jack 5 i.e. centering voluntarily.At the trial, be totally released by Hanging bolt assembly 4, start oil pump to jack 5 for pressure oil, jack piston is up, pushing reaction plate 3, loads the detected object such as foundation pile, ground.After off-test, treat that jack piston is regained, then with Hanging bolt assembly 4, girder beam body 1 and jack 5 are connected into entirety, in order to follow-up lifting and transport.

Claims (2)

1. the embedded static loading test girder of jack, the jack being provided with bottom opening in the middle of beam body embeds chamber, embed two ends, chamber and have gusset, embedding top of chamber is jack reaction plate, embed chamber two bottom sides and be provided with support bar, the weakening of chamber structure to girder bearing capacity is embedded for compensating, firmly entirety is welded into upper-part, it is characterized in that: jack embeds chamber height slightly larger than jack body height, under ensureing non-test state, jack can enter beam body by bank completely, jack embeds chamber bottom port can ensure jack shell, oil connection, free-extensions such as oil pipe and mutually not interfering.
2. the embedded static loading test girder of jack according to claim 1, it is characterized in that: jack reaction plate and jack closure stud hole correspondence position leave jack suppending hole, under non-test state, by Hanging bolt assembly, beam body and jack are held together, and need Hanging bolt assembly to be totally released at the trial.
