Description

Single-column lower anchor rod foundation

Technical Field

The utility model relates to an anchor rod basis under single-column belongs to stand basis technical field.

Background

When the existing column foundation is constructed, the installation of the U-shaped screw rod needs to be righted by hands after a template is built and then poured until concrete is solidified, so that the problems of troublesome construction and labor consumption are caused.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: provides a single-column lower anchor rod foundation to overcome the defects of the prior art.

The technical scheme of the utility model is that: a single-post lower anchor foundation comprising:

drilling holes, wherein the drilling holes are formed in the upper surface of the slope-changing ladder;

the two arms of the inverted U-shaped anchor rod are inserted into the 2 drill holes, and the part of the inverted U-shaped anchor rod inserted into the drill holes is fixedly connected with the drill holes through concrete slurry;

the concrete buttress is fixedly connected to the ground exposed part of the inverted U-shaped anchor rod;

the lower end of the U-shaped screw is welded on the connecting plate, and the two arm directions of the U-shaped screw are perpendicular to the connecting plate;

the connecting plate, connecting plate fixed connection exposes ground position at the type of falling U stock, and the connecting plate is perpendicular with vertical direction.

Further, the concrete slurry of the drilled hole adopts C35 high-strength non-shrinkage fine-stone concrete, and the concrete buttress adopts C30 concrete for pouring.

Further, the part of the inverted U-shaped anchor rod inserted into the drill hole is of a screw structure.

The utility model has the advantages that: the utility model discloses a with U type screw rod and connecting plate fixed connection to the both arms direction of U type screw rod is perpendicular with the connecting plate, puts the connecting plate in the template after having built the template and ensure that the template direction is perpendicular with vertical direction, thereby has guaranteed that the both arms direction of U type screw rod is parallel with vertical direction, need not hand U type screw rod and until the concrete solidifies, and the construction is more simple, consumes the manpower still less.

Detailed Description

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention; the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance, and furthermore, unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "connected" are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In order to better understand the technical solutions, the technical solutions will be described in detail below with reference to the drawings and the detailed description.

Example 1 was carried out: referring to fig. 1-2, a single-post lower anchor foundation, comprising: a drill hole 5-1 is drilled, and the drill hole 5-1 is formed in the upper surface of the slope changing ladder 1; the anchor rod 5-3 is of an inverted U shape, two arms of the anchor rod 5-3 are inserted into 2 drill holes 5-1, and the part of the anchor rod 5-3 inserted into the drill hole 5-1 is fixedly connected with the drill hole 5-1 through concrete slurry 5-2; the concrete buttress 5-6 is fixedly connected to the part, exposed out of the ground, of the inverted U-shaped anchor rod 5-3; the lower end of the U-shaped screw 5-5 is welded on the connecting plate 5-4, and the two arm directions of the U-shaped screw 5-5 are perpendicular to the connecting plate; and the connecting plate 5-4 is fixedly connected to the part, exposed out of the ground, of the inverted U-shaped anchor rod 5-3, and the connecting plate 5-4 is vertical to the vertical direction.

The U-shaped screw rods 5-5 are fixedly connected with the connecting plates 5-4, the two arm directions of the U-shaped screw rods 5-5 are perpendicular to the connecting plates, the connecting plates are placed in the formwork after the formwork is built, and the direction of the formwork is perpendicular to the vertical direction, so that the two arm directions of the U-shaped screw rods 5-5 are parallel to the vertical direction, the U-shaped screw rods do not need to be held by hands until concrete is solidified, construction is simpler, and less manpower is consumed.

Further, C35 high-strength shrinkage-free fine aggregate concrete is adopted as the concrete slurry 5-2 of the drill hole 5-1, and C30 concrete is adopted as the concrete buttress 5-6.

So that the column foundation 2 has sufficient strength.

Further, the part of the inverted U-shaped anchor rod 5-3 inserted into the drill hole 5-1 is of a screw structure.

The contact area between the part of the U-shaped anchor rod 5-3 inserted into the drill hole 5-1 and the concrete slurry 5-2 is increased, so that the connection between the U-shaped anchor rod 5-3 and the drill hole 5-1 is more firm.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
