Abstract
The utility model discloses a kind of pile crown structures convenient for Rapid Implementation static test, including the short lattice column being inserted at the top of steel reinforcement cage, multiple spaced apart connecting rods are equipped between the short lattice column and the steel reinforcement cage, the top of the short lattice column is protruded on the steel reinforcement cage, is connected with Horizontal load-bearing steel plate at the top of the short lattice column；The filling concrete height of pile crown is higher by the high 0.5~1m of top mark of the short lattice column.The structure that the utility model welds load-bearing steel plate by using short lattice column pre-buried in the top of steel reinforcement cage and on short lattice column replaces traditional reinforced mesh, it eliminates and cast-in-place builds concrete construction process, to save the strong time such as pile crown of static test, the construction speed at scene is accelerated.
Description
Technical field
The utility model relates to a kind of pile crown structure, especially a kind of pile crown structure convenient for Rapid Implementation static test.
Background technique
Static test is widely used in railway traffic engineering vehicle as one of the important method for determining bearing capacity of borehole bored concrete pile
Stand or the deep-foundation pit engineering of house construction engineering in, the general preloading of static test is larger, needs to carry out the pile crown of cast-in-situ bored pile
Processing increases cast-in-place concrete after reinforced mesh, and the strong time such as scene is longer, seriously affects the construction speed at scene, therefore compel
It is essential and wants a kind of pile crown structure convenient for Rapid Implementation static test.
Summary of the invention
The utility model is to solve technical problem present in well-known technique and provide a kind of convenient for the examination of Rapid Implementation static load
The pile crown structure tested.
The utility model is adopted the technical scheme that solve technical problem present in well-known technique: one kind is convenient for fast
Speed implements the pile crown structure of static test, including the short lattice column being inserted at the top of steel reinforcement cage, in the short lattice column and institute
State between steel reinforcement cage be equipped with multiple spaced apart connecting rods, the short lattice column top protrusion the steel reinforcement cage it
On, Horizontal load-bearing steel plate is connected at the top of the short lattice column；The filling concrete height of pile crown is higher by the short lattice
High 0.5~the 1m of the top mark of column.
The top mark height of the short lattice column is higher by 20~30cm than the design stake top absolute altitude of cast-in-situ bored pile.
The short lattice column be made of steel plate, the steel plate with a thickness of 16~25mm.
The connecting rod is made of any one in reinforcing bar, steel plate or fashioned iron.
The Horizontal load-bearing steel plate uses square structure, and side length is more than or equal to the diameter of cast-in-situ bored pile, with a thickness of 2~
4cm。
The utility model has the advantages and positive effects of: by using short lattice column pre-buried in the top of steel reinforcement cage
And weld the structure of load-bearing steel plate on short lattice column and replace traditional reinforced mesh, it eliminates and cast-in-place builds concrete construction
Sequence accelerates the construction speed at scene to save the strong time such as pile crown of static test.
Detailed description of the invention
Fig. 1 is the sectional side elevation of the utility model；
Fig. 2 is the top view of Fig. 1 (removing Horizontal load-bearing steel plate).
In figure: 1, steel reinforcement cage；2, short lattice column；3, Horizontal load-bearing steel plate；4, connecting rod；5, the concrete of pile crown.
Specific embodiment
For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates
Detailed description are as follows for attached drawing:
Fig. 1 and Fig. 2, a kind of pile crown structure convenient for Rapid Implementation static test are please referred to, including is inserted into the top of steel reinforcement cage 1
Short lattice column 2 in portion is equipped with multiple spaced apart connecting rods 4 between the short lattice column 2 and the steel reinforcement cage 1,
The top of the short lattice column 2 is protruded on the steel reinforcement cage 1, is connected with Horizontal load-bearing at the top of the short lattice column 2
Steel plate 3；5 influx height of concrete of pile crown is higher by the high 0.5~1m of top mark of the short lattice column 2.
In the present embodiment, the top mark height of the short lattice column 2 be higher by 20 than the design stake top absolute altitude of cast-in-situ bored pile~
30cm.The short lattice column 2 be made of steel plate, the steel plate with a thickness of 16~25mm.The connecting rod 4 is by steel
Made of any one in muscle, steel plate or fashioned iron.The Horizontal load-bearing steel plate 3 uses square structure, and side length is more than or equal to
The diameter of cast-in-situ bored pile, with a thickness of 2~4cm.
The construction procedure of the utility model are as follows:
1) during construction drill filling pile cage of reinforcement, short lattice column and steel reinforcement cage are connected with prefabricated connecting rod
It connects securely；
2) it transfers in steel reinforcement cage to the hole being drilled, and casting concrete；
3) concrete of hole pouring pile to be drilled reaches design strength, cuts the concrete dross of cast-in-situ bored pile stake top, makes
Expose at the top of short lattice column；
4) by Horizontal load-bearing steel plate and short lattice column firm welding.
Although being described above in conjunction with preferred embodiment of the attached drawing to the utility model, the utility model is not
It is confined to above-mentioned specific embodiment, the above mentioned embodiment is only schematical, is not restrictive, ability
The those of ordinary skill in domain is not departing from the utility model aims and claimed under the enlightenment of the utility model
In the case where range, many forms can also be made, these are belonged within the protection scope of the utility model.
