Description
Technical field
The utility model relates to water construction testing equipment, especially for a kind of plane-plate loading test bearing device of building detection of compound foundation, dark/shallow-layer load plate test technology.
Background technology
In water construction, when traditional detection of compound foundation or plane-plate loading test, adopt general steel plate as bearing plate, simulate the native pressure bearing jack and transmit of ground identical with steel plate area base, at the loading initial stage, within the scope of steel plate, same load intensity can be born, stressed comparatively even.Because jack is positioned over steel plate central authorities, along with jack pressurization, steel plate insufficient rigidity, corner tilts, and only has and just can bear top descend load to soil (or stake) under jack, do not conform to, cause test failure with ideal test status pole.Developing for this reason and a kind ofly under high-pressure state, still can keep integral rigidity and jack load can be uniformly distributed bearing plate equipment within the required range, is the technical problem that must solve as early as possible during architecture foundation pile detects.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of plane-plate loading test bearing device, effectively can solve and under high-pressure state, still can keep integral rigidity and jack load can be uniformly distributed problem within the required range.
The technical scheme that the utility model solves is, comprise top steel plate, steel plate is protected in lower steel plate and side, the center of top steel plate and lower steel plate is on same vertical line, top steel plate and lower steel plate are the parallel shape of level, the horizontal plane of top steel plate is less than the horizontal plane of lower steel plate, it is by bevel phase that steel plate is protected in side, horizontal segment and vertical section weld together successively and form up-small and down-big step-like ducted body, ducted body top is together with the steel plate perimeter mounted of top, ducted body bottom forms Concrete Filled storehouse together with the perimeter mounted of lower steel plate, fill in storehouse and be filled with concrete, jack perpendicular to top steel plate is housed above the center of top steel plate.
The utility model structure is simple, easily prepares, easy to use, effective, long service life, and effectively ensure that does not affect by external force in the testing environment of complexity, and make measurement more accurate, guarantee pile detection is the innovation on pile detection equipment.
Accompanying drawing explanation
Fig. 1 is cross-section structure front view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
As shown in Figure 1, the utility model steel plate comprises top steel plate, steel plate is protected in lower steel plate and side, the center of top steel plate 3 and lower steel plate 1 is on same vertical line, top steel plate and lower steel plate are the parallel shape of level, the horizontal plane of top steel plate is less than the horizontal plane of lower steel plate, it is by bevel phase 2-1 that steel plate 2 is protected in side, horizontal segment 2-2 and vertical section 2-3 welds together successively and forms up-small and down-big step-like ducted body, ducted body top is together with the steel plate perimeter mounted of top, ducted body bottom forms Concrete Filled storehouse together with the perimeter mounted of lower steel plate, fill in storehouse and be filled with concrete 5, jack 4 perpendicular to top steel plate is housed above the center of top steel plate.
In order to ensure result of use, described top steel plate, lower steel plate are circle; The longitudinal section in described filling storehouse is isosceles trapezoid; The point of contact A of top, the longitudinal section steel plate periphery in described filling storehouse is to the isosceles triangle (see dotted line in figure Suo Shi) that to form with vertical line point B between the vertical line point B and bevel phase 2-1 lower extreme point C of lower steel plate be drift angle.
In actual production, upper lower steel plate of the present utility model, side protect steel plate, concrete solid, during single production, it is of a size of fixed value, if batch production, can incorporation engineering actual conditions making base area be the bearing plate of different-diameter, to meet the needs in multiple situation.
The utility model is when testing use, bearing device is placed on pilot region, bearing plate upper steel plate home position will be placed in jack pair, afterburning by jack, bearing plate entirety moves down, for lower steel plate place foundation soil provides evenly distributed load power, because this bearing plate Whole Equipment rigidity is higher, there will not be corner to upwarp situation, and Each part, plate size and concrete reinforcement all pass through calculating, be enough to realize the uniform distribution of point load and self do not produce distortion or destroy.
Compared with prior art, tool has the following advantages the utility model:
1. test accurately
Because this Whole Equipment can not produce distortion, the situation that four limits upwarp particularly can not be produced, thus more even to jack resolution of forces, and under better simulation Practical Project state, the loading characteristic of foundation soil, ensures Construction Quality.
2. firmly durable, the life-span is long
Traditional steel plate produces excessive deformation under the effect of cyclic reverse loading, application life is shorter, this device surrounding does retaining wall with steel plate, upper lower steel plate is strengthened, the concrete of interior note high strength, can ensure not affect by external force in the testing environment of complexity, ensures test effect, more firmly durable, there is very strong actual application value.
Claims (4)
