DETAILED DESCRIPTION

The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They 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 therefore should not be understood as a limitation on the present invention.

It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

An embodiment of the utility model provides a pile connection assembly, as shown in Figures 1 and 2, comprising an upper section pile 110, a lower section pile 120 located below the upper section pile 110, and a connecting plate 200, wherein the upper section pile 110 and the lower section pile 120 both comprise a pile body made of concrete, and the ends of the pile bodies of the upper section pile 110 and the lower section pile 120 that are butt-jointed to each other are both provided with end plates and pile collars, specifically, an upper end plate 310 is fixed to the end face of the lower end of the pile body of the upper section pile 110, an upper pile collar 410 is fixed to the circumferential surface of the lower end of the pile body of the upper section pile 110, a lower end plate 320 is fixed to the end face of the lower end of the pile body of the lower section pile 120, and a lower pile collar 420 is fixed to the circumferential surface of the lower end of the pile body of the lower section pile 120. The upper end plate 310 and the lower end plate 320 can be closely attached together, and the connecting plate 200 is respectively connected to the upper pile hoop 410 of the upper section pile 110 and the lower pile hoop 420 of the lower section pile 120, thereby connecting the upper section pile 110 and the lower section pile 120 together. Anchors 510 are provided on the inner side of the upper pile hoop 410 and the lower pile hoop 420. The anchors 510 on the inner side of the upper pile hoop 410 are buried in the pile body of the upper section pile 110, and the anchors 510 on the inner side of the lower pile hoop 420 are buried in the pile body of the lower section pile 120. In this way, the deep anchor connection between the pile hoop and the pile body is achieved. Even if the pile body is damaged, the pile hoop will not be separated from the pile body, and the pile hoop plays a role in continuous protection of the pile body. At the same time, under tensile, bending or shearing conditions, the pile body can transfer stress to the pile sleeve through the anchor 510. The pile sleeve and the anchor 510 can share part of the tensile force on the main reinforcement of the pile body, reducing the risk of main reinforcement head fracture, thereby ensuring the mechanical properties of the pile joint.

In some embodiments, a steel cage may be buried in the pile body. When manufacturing the upper section pile 110 or the lower section pile 120 of this embodiment, the steel cage and the pile sleeve with the anchor 510 may be placed in a pile making mold, and concrete will flow into the inner side of the pile sleeve, so that the anchor 510 is buried in the concrete of the pile body, which can greatly enhance the connection strength between the pile sleeve and the pile body.

In some embodiments, as shown in FIG. 3 and FIG. 4 , a connector 520 is fixed to the inner side of the pile hoop 400, one end of the anchor 510 is detachably connected to the connector 520, and the other end extends to the inner side of the pile hoop 400. Due to the detachable connection, it is convenient to connect the anchor 510 with the connector 520 during the manufacturing process of the pipe pile. The connector 520 can be first fixed to the inner side of the pile hoop 400, the steel cage is placed in the pile hoop 400 without the anchor 510, and then the anchor 510 is connected to the connector 520, so that the connector 520 will not hinder the steel cage from being placed inside the pile hoop 400, and after the steel cage is placed in place, the connector 520 can be easily connected to the connector 520.

Furthermore, the connecting member 520 is a nut, and the anchoring member 510 is an anchoring screw. The axial direction of the nut may be toward the center of the pile sleeve 400. For example, when the pile sleeve 400 is a cylindrical structure, the axial direction of the nut extends along the radial direction of the pile sleeve 400. The anchoring screw can be connected to the nut or separated from the nut by screwing the anchoring screw, which is more convenient to operate. At the same time, the surface threads of the anchoring screw are densely covered, so the gripping force between the anchoring screw and the concrete is stronger, which can improve the connection strength between the pile sleeve 40 and the pile body; the anchoring screw has a head. After the pile is formed, the head of the anchoring screw is equivalent to forming a pier head embedded in the concrete, which is more evenly stressed and less likely to be pulled out of the concrete.

Furthermore, the nut is fixed to the inner side surface of the pile sleeve 400 by welding, the cross section of the nut is larger, the weld length is longer than the weld of the conventional shear nail, and the shear resistance is better.

In some embodiments, the anchors 510 are evenly distributed on the inner side of the pile hoop 400 along the circumference of the pile hoop 400, which makes the pile hoop 400 more evenly stressed and the concrete of the pile body is not easily deformed or displaced laterally from a part. A plurality of anchor groups are distributed in the axial direction of the pile hoop 400, each anchor group includes a plurality of anchors 510, which is equivalent to increasing the number of anchors 510, and the anchors 510 are also distributed at different positions in the axial direction of the pile hoop 400, which can further strengthen the connection strength between the pile hoop 400 and the pile body.

In some embodiments, as shown in FIG. 2 , the upper end and the lower end of the connection plate 200 are respectively welded and fixed to the upper pile hoop 410 of the upper section pile 110 and the lower pile hoop 420 of the lower section pile 120, and two groups of fixing members 210 are provided on the connection plate 200, one group of fixing members 210 fixes the connection plate 200 and the upper pile hoop 410 of the upper section pile 110 together, and the other group of fixing members 210 fixes the connection plate 200 and the lower pile hoop 420 of the lower section pile 120 together. In this way, the connection plate connects the pile hoops of the two sections of the pile by a composite connection method of mechanical connection and welding, so that the stress between the upper section pile 110 and the lower section pile 120 is transmitted through the pile hoop, further sharing part of the tensile force on the main reinforcement pier head of the pile body, reducing the risk of premature fracture of the main reinforcement pier head, and thus ensuring the mechanical properties of the pile joint.

The connecting plate 200 matches the outer shape of the pile collar. The connecting plate 200 can be a combination of several separate steel plates or a complete annular steel plate, so that it can be attached to the outside of the pile collar to facilitate welding and fixing the two later. The welding position can surround the pile collar to form a first weld 610.

Further, as shown in FIG. 2 and FIG. 3 , the fixing member 210 is a bolt, a through-hole is provided on the connection plate 200, and a threaded hole 401 corresponding to the through-hole is provided on the pile collar 400, and the bolt passes through the through-hole and is fixed in the threaded hole. The connection plate 200 and the pile collar 400 can be quickly mechanically connected by bolts, and the mechanical connection has high pull-out resistance and high construction efficiency, and also provides the function of fixing the connection plate 200 for the subsequent welding of the connection plate 200 and the pile collar 400, and also guarantees the quality of the welding seam to a certain extent.

In some embodiments, the upper end plate 310 of the upper pile 110 and the lower end plate 320 of the lower pile 120 are closely attached to each other and welded to strengthen the connection strength between the end plates, and a full weld may be formed around the outer circumference of the end plates to form a second weld.

Furthermore, the upper pile hoop 410 of the upper pile section 110 is welded and fixed to the edge of the upper end plate 310 of the upper pile section 110, and the lower pile hoop 420 of the lower pile section 120 is welded and fixed to the edge of the lower end plate 320 of the lower pile section 120. Thus, on the basis of the traditional welding between the end plates, the mechanical connection between the connecting plate 200 and the pile hoop and the welding between the end plate and the pile hoop are added, so that the bending and tensile stress nodes of the pile body are shared from the single end plate welding to the entire area covered by the pile hoop, thereby improving the safety factor of the structure. The welding has low process requirements and greater connection strength. Specifically, a full circle welding method can be adopted to form a third weld 630 on the inner side of the pile hoop.

In some embodiments, the pile collar 400 is embedded in the circumference of the pile body, so that the outer circumference of the pile collar 400 is flush with the outer circumference of the pile body, and the circumference of the entire pipe pile is smoother, which is convenient for pile sinking.

Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
