Abstract
A box-girder of a foundation pile static load test loading reactive test system has a closed box-shaped metal structure extending along the length direction; a symmetric position between opposite lateral walls in the length direction is provided with a connecting through hole for a connecting structure to pass through; and a plurality of baffled reinforcing structures with the circumferences all tightly connected with all circumferential walls extending in the length direction are arranged in the box-shaped structure along the length direction in an alternative arrangement way. The pile-loading platform of the foundation pile static load test loading reactive test system, which is constructed by the box-girder, has high security and bearing capacity and can be used in a separated or combined way according to needs with flexible adjustment and high applicability.
Description
Technical field
The utility model relates to a kind of spandrel girder structure that foundation pile static loading test loading counter-force test macro is constructed the preloading platform that is used for.
Background technology
Therefore the quality of building foundation will directly influence the total quality of building, and by static loading test loading counter-force test macro the foundation pile of building being carried out static loading test is to guarantee important detection link in the construction quality.The static loading test counter force system of traditional approach mainly contains anchoring pile crossbeam counterforce device system, preloading reaction beam apparatus system etc.Its basic principle all is by the detecting instrument that jack is set at tested foundation pile top and cooperates with it, the supporting capacity of tested foundation pile being exerted pressure through the corresponding constructed counter-force platform of girder construction is detected realize.With the heavy formula test macro of heap commonly used is example, being constructed by shaped steel earlier can be by the corresponding bearing platform (being preloading reaction beam device) of jack institute support, pile up weight then thereon, dependence is placed on jack between bearing platform and tested pile crown with platform jack-up progressively, thereby power is applied on the tested pile crown, to detect the supporting capacity of this tested foundation pile.Because the girder in its counterforce device is perpendicularly put shaped steel and is combined by some, the usage quantity of shaped steel during according to testing experiment the size of required preloading decide.Combine the counterforce device of girder construction by some vertical shaped steel, not only bearing capacity is generally relatively low, and because of the globality difference between each shaped steel in forming has caused its stability poor, the insecurity factor that detects in the process of the test is more.
The utility model content
Given this, it is a kind of simple in structure that the utility model will provide, and bearing capacity is big, safe, the adaptable box beam that is used for foundation pile static loading test loading counter-force test macro.
The utility model is used for the structure of the box beam of foundation pile static loading test loading counter-force test macro, a closed box-shaped metal structure that extends is along its length arranged, antimere place between the opposing sidewalls of its length direction is provided with the connecting through hole that can run through casing for syndeton, is provided with some peripheries and all tight iris type reinforcement that links to each other of each perisporium that extends at length direction along its length direction in the mode of being intervally arranged in the box structure body.
Because in foundation pile static loading test loading counter-force test macro, the bearing platform that the box-girder of the utility model said structure is constructed, be the gravity carrying transferring structure between bearing platform and jack, it is essential therefore in said box structure body the dividing plate reinforcement being set.Form specifically is set different choice can be arranged, for example can adopt the reinforcement that makes each iris type with mode parallel arrangement setting perpendicular to casing length bearing of trend, also can be subjected to force direction and/or mode when using adopt mode to be provided with suitable angle of inclination, or adopt mode to be provided with above-mentioned multi-form mutual combination such as vertical, oblique, to reach required and/or best load-bearing effect.
As above-mentioned, the top of this box-girder is the counter-force bearing platform, and the below is a jack, its stressed site of action and unbalanced unanimity.For this reason, on the said structure basis, can also further make each iris type reinforcement in the said box structure body is that the form that the spacing of adjacent two reinforcements is strengthened to two ends gradually by the length middle part of box structure body is arranged, so that it can have more scientific and reasonable stressed effect.
During use, the size of required bearing capacity during according to the detection test, the box-girder of the utility model said structure can use separately, also can will be used in combination mutually with two or more independently box-girder bodies.When being used in combination, can use the connector as appropriate formats such as stay bolts, symmetrically arranged corresponding connecting through hole gets final product after it is fastenedly connected mutually between this opposing sidewalls in each box girder structure.
The box-girder of the utility model said structure form can be widely used in as present multiple foundation pile static loading test loading counter-force test macros commonly used such as anchoring pile crossbeam counterforce device, the heavy platform counterforce devices of artificial sand pocket heap, and simple in structure, is easy to promote.Result of the test shows that the above-mentioned box-girder of the utility model can be used for large-tonnage castinplace pile static loading tests such as 600-1200 ton, and bearing capacity is big, and is safe, and combination is adjusted flexibly, and is reliable convenient.
Below in conjunction with the specific embodiment of accompanying drawing illustrated embodiment, foregoing of the present utility model is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
Description of drawings
Fig. 1 is the box beam structural representation of the utility model foundation pile static loading test loading counter-force test macro.
Fig. 2 is the schematic diagram of the A-A sectional structure among Fig. 1.
The specific embodiment
The utility model as shown in the figure is used for the box beam of foundation pile static loading test loading counter-force test macro, a closed box-shaped metal structure 1 that extends is along its length arranged in the structure, and the antimere place between the opposing sidewalls of its length direction is provided with that some intervals are provided with can be used for the connecting through hole 2 that syndeton such as bolt runs through casing.In box structure body 1, be provided with some peripheries and all tight iris type reinforcement 3 that links to each other of each perisporium that extends at length direction in the mode of being intervally arranged along its length direction.Each iris type reinforcement 3 all is provided with the mode parallel arrangement perpendicular to casing length bearing of trend, and the form that strengthens gradually to two ends in the middle part of the length of spacing by the box structure body of each iris type reinforcement 3 for adjacent two reinforcements 3 is arranged.According to using needs, between some or whole adjacent reinforcements 3, can also increase the oblique reinforcement that is provided with oblique diagonal manner.These can according to or the concrete stressed needs that adapt to its load-bearing decide, to obtain best load-bearing stressed effect.
