Abstract
The utility model relates to the structure improvement of construction piles, particularly a wolf-tooth rod construction pile, which belongs to the technical field of construction engineering. The construction pile comprises a hollow pile pipe, wherein one end of the pile pipe is provided with a cone-shaped pile head. The improvement of the utility model is that the side wall of the pile pipe is provided with pin holes, pile pins are arranged in the pin holes and the length of the pile pins is larger than the thickness of the pipe wall. Before construction, the outer end of the pile pin does not extend out the pile wall, therefore the construction pile of the utility model can be pressed in foundation soil as ordinary static pressure piles; after construction, a conical head or a screw column is inserted into the center hole of the pile pipe and the pile pins in the pin holes of the pipe wall are pushed out of the pile wall one by using bevel action. Finally, the whole construction pile is in the shape of a wolf-tooth rod, and has the longitudinal wedging action of the pile pipe and the transverse wedging action of the pile pins with soil so as to enhance firmness performance.
Description
Technical field
The utility model relates to a kind of building stake, and especially a kind of architecture advances of building stake belongs to construction engineering technical field.
Background technology
Build before the high-lager building, laying earlier the building stake on ground is present common construction techniques.No matter be solid pricker stake, or hollow pile for prestressed pipe (being commonly called as static pressed pile), after hammering or being pressed into building lot, owing to hammer into blockishness, soil all around there is squeezing action, therefore not only than the casting stake work efficiency height that digs a well as nail, and frictional force is big, and is more solid firm.
Yet above-mentioned existing building stake can't further produce the wedging function of horizontal direction except the side friction of vertical direction, so its solid steadiness is restricted.
The utility model content
The purpose of this utility model is: at the shortcoming that above prior art exists, proposes a kind ofly not only can produce side friction, but also have the wolf's fang bar type building of horizontal wedging function, thereby its solid steadiness is significantly improved.
In order to reach above purpose, wolf's fang bar type building of the present utility model stake comprises hollow stake pipe, one end of described stake pipe is equipped with the taper pile crown, and its improvements are: the sidewall of described stake pipe is shaped on pin-and-hole, and the stake pin of length greater than pipe thickness is housed in the described pin-and-hole.
Before the construction, pile lining is not stretched out in stake pin outer end, and building stake therefore of the present utility model can be pressed into foundation soil as common pile for prestressed pipe.Afterwards, from the centre bore of stake pipe, insert conehead or borded pile, utilize ramp effect, the stake pin in the tube wall pin-and-hole is ejected pile lining one by one.Final whole building stake is just as the wolf pressure bar, and vertical side friction of existing stake pipe between the soil, also has the stake pin laterally to agree with the active force of generation, and its solid steadiness improves greatly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structural representation after Fig. 1 embodiment construction.
The specific embodiment
Embodiment one
The wolf's fang bar type building stake of present embodiment is made of hollow cylindrical stake pipe 2, conical pile crown 3 and some pins 1 as shown in Figure 1.The lower end of the shank plug-in mounting stake pipe 2 of taper pile crown 3, the sidewall of stake pipe is shaped on some pin-and-holes, and wherein plug-in mounting length is greater than the stake pin 1 of pipe thickness.
Before the construction, as shown in Figure 1, pile lining is not stretched out in stake pin outer end, so job practices is identical with existing static pressed pile.The stake pipe is pressed into after the foundation soil, again by the conehead stem stem that can insert a tube hub hole, with the same static pressure equipment of piling, presses down stem stem, utilizes the ramp effect of conehead, and the stake pin in the tube wall pin-and-hole is ejected pile lining one by one, and as shown in Figure 2, it is bar-shaped to form wolf's fang.Finally, existing vertical side friction between pile body and the soil, also horizontal wedging function power is arranged, as calculated, its solid steadiness can significantly improve.
In addition to the implementation, the utility model can also have other embodiments.For example, the stake tube section is square; Taper is made in stake pin outer end, so that laterally wedging; Pin-and-hole can stud with lining, thereby more firm solid; Or the like.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (4)
1. wolf's fang bar type building stake comprises hollow stake pipe, and an end of described stake pipe is equipped with the taper pile crown, it is characterized in that: the sidewall of described stake pipe is shaped on pin-and-hole, and the stake pin of length greater than pipe thickness is housed in the described pin-and-hole.
2. according to the stake of the described wolf's fang bar type building of claim 1, it is characterized in that: described pin-and-hole studs with lining.
3. according to claim 1 or 2 described wolf's fang bar type building stakes, it is characterized in that: taper is made in described stake pin outer end.
4. according to the stake of the described wolf's fang bar type building of claim 3, it is characterized in that: described pile crown is for conical, and the shank of pile crown is inserted into stake pipe lower end.
