Technical Field

The application relates to the technical field of building construction, in particular to an elastic clamping type connecting piece for a concrete precast pile.

Background

The precast pile is made of various materials and various forms (such as wooden pile, concrete square pile, prestressed concrete tubular pile, steel pile, etc.) in factory or construction site, and is driven, pressed or vibrated into the soil by pile sinking equipment. The construction method mainly comprises two main types of concrete precast piles and steel piles in the field of Chinese building construction, wherein the concrete precast piles can bear larger load, are firm and durable and have high construction speed, are one of widely applied pile types and are commonly used concrete solid square piles and prestressed concrete hollow pipe piles.

In actual construction, the lengths of the precast concrete piles buried under the ground surface are different depending on the soil texture and the terrain of each area, but the lengths of the individual precast concrete piles are limited due to the limitation of the materials and transportation conditions used for the precast concrete piles, and therefore, when the lengths of the precast concrete piles buried under the ground surface need to be increased, a plurality of precast concrete piles must be effectively connected to form a long pile body.

Regarding the connection problem between a plurality of precast concrete piles, reference may be made to chinese patent application with publication number CN104947658A, which discloses a snap-type connection member: the large nut sleeve is in threaded connection with the connecting piece, a plurality of bent elastic pieces are arranged on the connecting piece in an annular array at one side of the large nut sleeve, and an included angle larger than 0 degree is formed between each bent elastic piece and the inner side wall of the large nut sleeve; one side of the inserted bar is in threaded connection with the small nut sleeve, the other side of the inserted bar is provided with an annular groove on the peripheral surface of the inserted bar, and the annular groove is far away from one side groove surface of the small nut sleeve and is arranged to be a blocking surface for limiting the bent elastic sheet clamped in the annular groove. During the use, install big nut sleeve and connecting piece at the head end of concrete precast pile, install little nut sleeve and inserted bar at the tail end of concrete precast pile, hoist and mount the concrete precast pile after that, make adjacent concrete precast pile head and the tail relative, when the inserted bar inserted the big nut sleeve who is equipped with the connecting piece, it is buckled the shell fragment and can be offered some fender faces in the annular spacing on the inserted bar, and then realizes that the connection of concrete precast pile is fixed.

In the related art, when adjacent precast concrete piles are not opposite end to end, the precast concrete piles need to be hoisted by a hoisting tool, the direction of the precast concrete piles is adjusted to be opposite end to the adjacent precast concrete piles, then the precast concrete piles can be fixedly connected through the connecting piece, the adjusting process is complicated, and the applicability of the connecting piece is low.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned part or whole technical problem, this application provides a concrete precast pile is with bullet card formula connecting piece, even it is not relative end to end between the adjacent concrete precast pile, also can realize concrete precast pile's connection fixed, and the suitability of bullet card formula connecting piece is higher.

The utility model provides a concrete precast pile is with bullet card formula connecting piece, it includes first nut sleeve, second nut sleeve and the inserted bar body, inserted bar body one end threaded connection in the first nut sleeve or in the second nut sleeve, the inserted bar body other end is inserted and is located in the second nut sleeve or in the first nut sleeve and with second nut sleeve or first nut sleeve joint, first nut sleeve and second nut sleeve pass through inserted bar body interconnect and fix.

By adopting the technical scheme, when in use, the first nut sleeve and the second nut sleeve are respectively installed (embedded) at the head end and the tail end of the concrete precast pile according to the construction process, it needs to be explained that the first nut sleeve and the second nut sleeve can be installed at the head end of the concrete precast pile and also can be installed at the tail end of the concrete precast pile, after the first nut sleeve and the second nut sleeve are installed, one end of the inserted rod body is in threaded connection with the first nut sleeve or the second nut sleeve, then the concrete precast pile is hoisted, and the other end of the inserted rod body is inserted into and clamped in the first nut sleeve or the second nut sleeve, so that effective connection among a plurality of concrete precast piles is realized The existing concrete precast pile is connected and fixed, the use is very convenient, and the applicability of the connecting piece is higher.
