Abstract
The utility model relates to a pile head fixer for the static load test of cast-in-place piles, which comprises a circular metal sleeve, the metal sleeve is provided with an opening and a fastening mechanism, the fastening mechanism comprises an upper fixing plate and a lower fixing plate which are arranged on the metal sleeve at both sides of the opening, and an adjustable bolt is arranged between the upper fixing plate and the lower fixing plate. Since the metal sleeve is provided with the opening and the adjustable connecting bolt is arranged on the metal sleeve, the metal sleeve can be conveniently mounted and dismounted, meanwhile, the verticality and level of the metal sleeve can be easily controlled when the metal sleeve is mounted, consequently, the remounting rate of the metal sleeve is effectively reduced, the waste of manpower and material resources is effectively reduced in the adjustment of the verticality and level of the metal sleeve, the fixer is more economic and can come up to the requirements of construction design, and the working efficiency is increased.
Description
Technical field
The utility model relates to a kind of engineering castinplace pile, specifically, relates to the fastening devices of pile crown in a kind of castinplace pile static loading test, belongs to technical field of buildings.
Background technology
Technical code for building pile foundation regulation: should adopt static loading test to determine the single pile vertical resistance pressure bearing capacity before the construction.The construction technology of traditional castinplace pile static loading test is as shown in Figure 1: behind the bored pile piling, at first measure the absolute altitude of filling pile head 6, the cylindric sealing steel bushing 7 that to make with steel sheet is connected and fixed with the reinforcing cage 9 of castinplace pile again, is lowered to the reinforcing cage 9 of castinplace pile then.Filling pile construction finishes, and when treating that concrete reaches certain intensity, filling pile head 6 is done static loading test.Wherein the effect of steel bushing 7 is to become one as strengthening the concrete of hoop with the filling pile head 6 of castinplace pile pile body 8 upper ends, and filling pile head 6 is strengthened, and prevents that filling pile head 6 is crushed when doing static loading test.But in the practice of construction when steel bushing is installed, exist steel bushing that verticality and the uppity problem of absolute altitude are installed, be difficult to reach the pile crown absolute altitude of designing requirement and the quality specifications that steel bushing is installed, after test finishes in addition, difficulty can't be removed or remove to steel bushing, very easily causes the waste of human and material resources.
The utility model content
Technical problem to be solved in the utility model is the problem at above-mentioned existence, the fastening devices that a kind of installation is provided, removes pile crown in the castinplace pile static loading test convenient, that cost is low.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: the fastening devices of pile crown in the castinplace pile static loading test, it is characterized in that: described fastening devices comprises the metallic sheath of annular, and described metallic sheath is provided with opening, and described metallic sheath is provided with retention mechanism.
The prioritization scheme of retention mechanism, described retention mechanism comprise upper mounted plate and the bottom plate that is arranged on the metallic sheath of opening both sides, are provided with the adjusting bolt between described upper mounted plate and the bottom plate.
The concrete prioritization scheme of opening, described number of openings are two.
The utility model adopts above technical scheme, compared with prior art, have the following advantages: metallic sheath is provided with opening, and metallic sheath is provided with adjustable connecting bolt, so, very convenient when installation and dismounting metallic sheath, control its verticality and absolute altitude when simultaneously metallic sheath being installed easily, rework rate when having reduced the metallic sheath installation effectively and the waste of the man power and material when adjusting its verticality and absolute altitude, more economically, cost is low, can reach the working design requirement, has improved operating efficiency.
Below in conjunction with the drawings and specific embodiments to the technical solution of the utility model further instruction:
