Description
Technical field
The utility model is related to static load test field more particularly to a kind of truss beam type dead load safe test beds.
Background technology
Static load test refers to the use function by stake, respectively stake top apply step by step axial compressive force, axial uplift force or
In pile foundation support table bottom surface, absolute altitude is unanimously located to apply horizontal force, observe sedimentation that the corresponding test point of stake generates at any time, on pull out position
Shifting or horizontal displacement, according to load single pile vertical resistance pressure bearing capacity corresponding with relationship (i.e. Q~S curve) judgement of displacement, list
The test method of stake vertically pulling-resistant bearing capacity or horizontal bearing capacity of single pile.
It is most widely used one in the current various methods for examining pile foundation (containing composite foundation, subsoil) bearing capacity
Kind, and it is acknowledged as test result most accurately, most reliably, it is put into various countries' pile foundation engineering specification or regulation.The research technique
Using the artificial loading of various methods, the actual working state on ground foundation simulation or basis tests load-carrying properties and deformation after its load
Feature.Its notable advantage is that stress condition is relatively practical, easy to use, test result it is intuitive and be easy to for it is appreciated that
And receiving；But experimental scale and expense are relatively large.
Presently, there are the problem of be that safety is poor, detection it is not accurate enough, test failure, which collapses to be susceptible to, injures people and Yang by a crashing object
The problem of dirt.
For this purpose, designing a kind of truss beam type dead load safe test bed, problem above is solved.
Invention content
The utility model is to overcome the above deficiency, provides a kind of truss beam type dead load safe test bed, including secure group
Part, truss support component and dead load component；
The security component includes that safe enclosing and safety are cheated, and the safety hole is the hole dug out on ground, the safety
Enclosing is located at the both sides cheated safely；
The truss support component includes two buttresses and girder truss, and two buttresses are located at the outside cheated safely
Both sides, and positioned at the inside of two safe enclosings；Girder truss includes crossbeam and vertical beam, and vertical beam rises between two crossbeams
There is reinforcing rib in the enclosed space of supporting role, the crossbeam and vertical beam；
The dead load component includes platform and several preloadings above platform；
The girder truss is horizontally placed above two buttresses, and crossbeam above is placed above platform, on the platform
It places preloading and carries out the increase and decrease of preloading according to the needs of static load test in face.
Further, the preloading is the heap bag of built-in sandstone.
Preferably, the platform is concrete slab.
The utility model has the beneficial effects that：
A kind of truss beam type dead load safe test bed described in the utility model, it is easy to use, dead load can be carried out
Experiment, while can ensure safety and prevent airborne dust.
Description of the drawings

Specific implementation mode
It is described in detail with reference to attached drawing below with reference to the embodiments of the present invention.
A kind of truss beam type dead load safe test bed, including security component, truss support component and dead load component；
The security component includes safe enclosing 1 and safety hole 4, and the safety hole 4 is the hole dug out on ground 9, described
Safe enclosing 1 is located at the both sides that the safety cheats 4；
The truss support component includes two buttresses 2 and girder truss, and two buttresses 2 are located at the safety and cheat 4
Both sides external, and positioned at the inside of two safe enclosings 1；Girder truss includes crossbeam 5 and vertical beam 6, and vertical beam 6 is located at two cross
It plays a supportive role between beam 5, there is reinforcing rib 7 in the enclosed space of the crossbeam 5 and vertical beam 6；
The dead load component includes platform 3 and several preloadings 8 above platform 3；
The girder truss is horizontally placed above two buttresses 2, and platform 3, the platform is placed above in crossbeam 5 above
3 are placed above preloading 8, according to the needs of static load test, carry out the increase and decrease of preloading 8.
Further, the preloading 8 is the heap bag of built-in sandstone.
Preferably, the platform 3 is concrete slab.
Application method：
The girder truss is horizontally placed above two buttresses 2, and platform 3, the platform is placed above in crossbeam 5 above
3 are placed above preloading 8, according to the needs of static load test, carry out the increase and decrease of preloading 8.
The safety hole 4 can accommodate the girder truss fallen and preloading 8 when the static load test fails；The peace
Shelves 1 are enclosed entirely and are injured by a crashing object in test failure, when falling by people and disorderly rolling for placing preloading 8 and girder truss, moreover it is possible to which effective keep off is raised
Dirt.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
