Abstract
The invention discloses a multi-nut-bed assembly type uplift resistance connector. The uplift resistance connector comprises a square end plate and two nut beds which are closely attached to two sides of the back of the end plate respectively, wherein an anti-rotation connecting plate is connected between two adjacent nut beds on two adjacent sides, and at least one nut bed is connected to one edge, of the anti-rotation connecting plate, which is connected to the nut bed; and openings of the nut beds are arranged outwards. The multi-nut bed assembly type uplift resistance connector has the advantages that: the connecting mode between to uplift resistance piles is changed, the joint between the two uplift resistance piles is prevented from being destroyed by groundwater, so that the tensile strength and the bending strength between the two end plates are increased, and the performance of the whole pile is improved.
Description
Technical field
The present invention relates to a kind of uplift pile, is a kind of many nut seats assembling resistance to plucking joint specifically.
Background technology
In foundation pile construction because many factors can produce pile extension phenomenon, in pile body connection procedure, most applications is to utilize the weldability of pile body metal end plate after pile body aligns, the electric welding of two end plates to be welded, be generally that regional buoyancy force of underground water no problem but that have because of the multiple phenomenon of geological condition is large and underground water is strong to the destructiveness of solder side, this kind leans on electric welding method of attachment can not reach Architectural Design Requirements.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of many nut seats assembling resistance to plucking joint that can improve tensile strength and flexural strength.
Technical scheme: in order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of many nut seats assembling resistance to plucking joint, comprise square endplate, and be close to two nut seats that arrange on each limit at the end plate back side, between adjacent two nut seats on adjacent both sides, be connected with anti-rotation junction plate, be connected with of described anti-rotation junction plate on the limit of nut seat and be also connected with at least one nut seat; The opening of all nut seats all outwardly.
The nut seat being located on same one side of described anti-rotation junction plate is arranged side by side; Such two groups of nut seats have more strengthened the shearing resistance moment of connecting bolt by anti-rotation junction plate.
In order to save production cost, the nut seat being located on same one side of described anti-rotation junction plate has two.
Described anti-rotation junction plate is that angle is the anti-rotation junction plate of L-type of 90 °.Form 90 degree angles, strengthened the turning moment of bolt to nut in the time of assembling.
Beneficial effect: compared with prior art, advantage of the present invention is: changed the connected mode between two uplift piles, the junction that can prevent two uplift piles is destroyed by underground water, thereby can improve two tensile strength and flexural strengths between end plate, thereby improves the performance of entirety stake.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is assembling drawing of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As depicted in figs. 1 and 2, a kind of double nut seat assembling resistance to plucking joint, comprise square endplate 1, and be close to two nut seats 2 that arrange on each limit at end plate 1 back side, between adjacent two nut seats 2 on adjacent both sides, be connected with anti-rotation junction plate 3, in anti-rotation junction plate 3 one has been connected with on the limit of nut seat 2 and has also been connected with at least one nut seat 2; All outwardly, anti-rotation junction plate 3 is that angle is the anti-rotation junction plate 3 of L-type of 90 ° to the opening of all nut seats 2, and the two ends of anti-rotation junction plate 3 are welded on respectively the bottom of nut seat 2.
The nut seat 2 being located on same one side of anti-rotation junction plate 3 is arranged side by side, certainly the nut seat 2 on this limit is The more the better, illustrate that pulling test strength is higher, but from the viewpoint of saving production cost, the nut seat 2 being located on same one side of anti-rotation junction plate 3 has two, and two can meet pulling test strength and required.
By the mode of electric welding, the two ends of anti-rotation junction plate 3 are welded on to the bottom of adjacent two nut seats 2 on adjacent both sides, then in anti-rotation junction plate 3 has been welded with on the limit of a nut seat 2 and has welded a nut seat 2 again, then concreting, nut seat 2, anti-rotation junction plate 3 are all in concrete structure like this, so just can make this junction plate be placed in the destruction that is not subject to underground water in concrete structure completely, thereby meet Architectural Design Requirements.
Shown in Fig. 3 is the assembling drawing of two uplift piles, when assembling, first the nut seat on upper pile body 2 and nut seat 2 symmetries on lower pile body are placed, then the end plate 1 of the end plate on upper pile body 1 and lower pile body is welded together, at upper pile body with above the symmetrical nut seat 2 of lower pile body, junction plate 4 is installed again, finally upper pile body and lower pile body are assembled together through junction plate 4 with bolt 5 respectively, so just can improve tensile strength and the flexural strength of 1 of two end plate, thereby improve the performance of entirety stake.What bolt 5 adopted is that diameter is the bolt of M18, on upper pile body, there is the bolt that has equally 12 M18 on the bolt of 12 M18, lower pile body, the high-strength bolt that is M18 by 24 specifications while assembling like this fixes, wherein the shearing resistance of every, the bolt of M18 is 110KN, the shearing resistance of 24 is 2640KN.M, by State Standard of the People's Republic of China JG/T2029-2010: the shearing resistance of Type B 500 is 371KN.M, therefore adopts the present invention to assemble, and shearing resistance is apparently higher than national standard.
