Abstract
In order to solve ground screw steel tubular pile and fossil fragments installation difficulty, easily appear local deformation and sunken problem, the utility model provides a prevent subsiding ground screw steel tubular pile, ring flange, bearing, outer sleeve and ground screw steel pipe that set gradually including top-down, ring flange and outer sleeve pass through the bearing and rotate the connection, outer sleeve lower extreme fixedly connected with strengthens the nut, ground screw steel pipe upper portion is coaxial to be set up inside the outer sleeve to ground screw steel pipe upper portion side surface still is provided with and strengthens nut threaded connection's external screw thread, strengthens the nut and is connected with screw sleeve and ring flange, and through the screw sleeve of adjusting ground screw steel tubular pile and fossil fragments connecting device, can be accurate to the millimeter with fossil fragments elevation control, improves fossil fragments construction roughness, reduces the roughness error of mating formation to prolong its life.
Description
Technical Field
The utility model relates to a ground screw steel pipe construction equipment technical field, in particular to prevent subsiding ground screw steel-pipe pile.
Background
The existing device is a ground screw steel pipe pile, the structure of the ground screw steel pipe pile mainly comprises a flange plate, a galvanized metal steel pipe pile, a helical blade and a conical head, the circular flange plate connection, the square flange plate connection, the rectangular flange plate fixing hole connection and the U-shaped connection can be divided according to the flange plate, and the hot forging round-tip type and the alloy head type can be divided according to different bottom conical end structural types.
Ground screw steel pipe pile is used for wooden plank road, the pile foundation of wooden platform more in afforestation construction, and current ground screw steel pipe pile is difficult for adjusting the elevation after the pile foundation bores into, leads to upper portion fossil fragments installation unevenness, and the later stage ground appears the uneven settlement back, and local deformation, sunken appear in wooden plank road, wooden platform, need pile again and lay, thereby pull out the stake and can lead to the stability that secondary pile was driven in the extrusion of surface soil layer atress, the maintenance cost is higher.
Disclosure of Invention
In order to solve the problem, the utility model provides a prevent subsiding ground screw steel tubular pile, the technical scheme of adoption as follows:
the utility model provides an anti-settling ground screw steel pipe pile, its characterized in that includes ring flange, bearing, outer sleeve and the ground screw steel pipe that top-down set gradually, ring flange and outer sleeve rotate through the bearing and connect, outer sleeve lower extreme fixedly connected with strengthens the nut, ground screw steel pipe upper portion is coaxial to be set up inside the outer sleeve to ground screw steel pipe upper portion side surface still is provided with the external screw thread with strengthening nut threaded connection.
Preferably, the bearing is a thrust ball bearing.
Preferably, the flange and the outer sleeve are respectively and fixedly connected to the upper end and the lower end of the thrust ball bearing race and the shaft ring.
The beneficial effects of the utility model reside in that:
the ground screw steel pipe pile is connected with the threaded sleeve and the flange disc through the reinforcing nut, and the height of the keel can be accurately controlled to a millimeter by adjusting the threaded sleeve of the ground screw steel pipe pile and keel connecting device, so that the construction flatness of the keel is improved, the paving flatness error is reduced, and the service life of the ground screw steel pipe pile is prolonged; the flange plate is rotatably connected with the threaded sleeve through the bearing, the flange plate rotates when the height is prevented from being adjusted, the height of the keel can be conveniently adjusted in the installation state, and therefore the problem that the local part of the keel is raised or sunk due to uneven settlement of a foundation or construction errors is solved conveniently, and maintenance cost is reduced.
Drawings
Fig. 1 is the structure schematic diagram of the utility model:
the device comprises a flange plate 1, a thrust ball bearing 2, an outer sleeve 3, a ground screw steel pipe pile 4 and a reinforcing nut 5.
Detailed Description
Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description of the present invention, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
The anti-settling ground screw steel pipe pile shown in fig. 1 comprises a flange plate 1, a thrust ball bearing 2, an outer sleeve 3 and a ground screw steel pipe 4 which are sequentially arranged from top to bottom, wherein a shaft ring of the thrust ball bearing 2 is fixedly connected with the lower end face of the flange plate 1, a ring seat of the thrust ball bearing 2 is fixedly connected with the upper end face of the outer sleeve 3, an external thread is arranged at the upper part of the ground screw steel pipe pile 1, in addition, a reinforcing nut 5 is coaxially and fixedly connected with the lower end of the outer sleeve 3, and the upper part of the ground screw steel pipe pile 1 is in threaded connection with the reinforcing nut 5.
The working principle of the device is as follows: after the ground screw steel pipe pile is drilled, the flange plate 1 is connected to the inner portion of the outer sleeve 3 through the reinforcing nut 5, then the positions of the outer sleeve 3 and the flange plate 1 on the ground screw steel pipe pile 1 are adjusted according to the design height of the ground screw steel pipe, so that the height of the flange plate 1 is adjusted, after the height adjustment of the flange plates 1 is completed, the keel framework and the flange plate 1 are welded one by one, the ground screw steel pipe pile 4 is in threaded adjustable connection with the outer sleeve 3 through the reinforcing nut, the relative position relation between the ground screw steel pipe pile 4 and the outer sleeve 3 and between the ground screw steel pipe pile 3 and the flange plate 1 in the height direction is conveniently adjusted, the outer sleeve 3 is in rotary connection with the flange plate 1 through the thrust ball bearing 2, and the rotation of the flange plate 1 is avoided.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements can be made, and these improvements should also be regarded as the protection scope of the present invention.
