The stake of a kind of building
Technical field
The utility model relates to building material technical field, refers to the stake of a kind of building especially.
Background technology
Showing under construction, building lot all needs to be made up of foundation pile, and its usual structure is, a cushion cap has been supported in the concrete column stake goed deep in soil by several jointly, to form a bearing unit of building.In the building process of building stake, basic building theory is, by building pile bearing building, makes building can not sedimentation, in current construction, stake holes is beaten to after enough dark, just can think, bottom stake holes, there is enough flintinesses, can building be supported, therefore, by perfusion or the mode of preformed pile, pile in stake holes, can construct building bearing unit.
Utility model content
The technical problems to be solved in the utility model is to provide the stake of a kind of building, is matched, have good supporting capacity by metal column jacket and concrete inner prop, and more firm by what set up that limited post makes building post fixing.
For solving the problems of the technologies described above, embodiment of the present utility model provides the stake of a kind of building, comprise outer stanchion, described outer stanchion low side is most advanced and sophisticated, is provided with cylindrical cavity in described outer stanchion, and described cylindrical cavity overlaps with column jacket pile center line, the upper symmetrical level of described outer stanchion is sliding some limited posts, be provided with slide block in described cylindrical cavity, institute's speed time its length is identical with cylindrical cavity diameter, and described slide block thickness reduces from top to bottom gradually.
As preferably, when described skid is to cylindrical cavity least significant end, shaping by interior stanchion by concreting in cylindrical cavity.
As preferably, the length of described limited post is slightly less than the radius of outer stanchion.
As preferably, described outer stanchion is metalline stake.
The beneficial effect of technique scheme of the present utility model is as follows: structure is simple, and technology is reasonable, with low cost, is matched, have good supporting capacity by metal column jacket and concrete inner prop; By laterally fixing limited post, building stake firmly can be fixed on ground, and in metal column jacket, concreting forms concrete inner prop, also plays fixation to limited post while strengthening the bearing capacity of building stake.

Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model provides the stake of a kind of building for existing deficiency, as depicted in figs. 1 and 2, comprise outer stanchion 3, described outer stanchion 3 low side is most advanced and sophisticated, and be provided with cylindrical cavity 2 in described outer stanchion 3, described cylindrical cavity 2 overlaps with outer stanchion 3 center line, the upper symmetrical level of described outer stanchion 3 is sliding some limited posts 4, be provided with slide block 1 in described cylindrical cavity 2, institute's speed time slide block 1 length is identical with cylindrical cavity 2 diameter, and described slide block 1 thickness reduces from top to bottom gradually.When described slide block 2 slides into cylindrical cavity 2 least significant end, shaping by interior stanchion by concreting in cylindrical cavity 2.The length of described limited post 4 is slightly less than the radius of outer stanchion 3.Described outer stanchion 3 is metalline stake.
Use principle of the present utility model, first outer stanchion 3 is knocked in ground, now limited post 4 is also in cylindrical cavity 2, then slide block 1 is knocked in bottom cylindrical cavity 2, because the thickness of slide block 1 increases from lower to upper gradually, so limited post 4 is pushed in the ground outside outer stanchion 3 to both sides while knocking in slide block 1, thus good fixation is played to building stake, then interior stanchion is formed to concreting in cylindrical cavity 2, thus enhance the bearing capacity of building stake, good fixation can also be played to limited post 4.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
