Abstract
The utility model discloses a multi-nut base assembly type pull-resistant joint which comprises a square end plate and two nut bases in tight fit with each edge at the back side of the end plate, wherein the two adjacent nut bases arranged on the two adjacent edges are connected with each other by an anti-rotation connecting plate, and the edge connected with the nut base of the anti-rotation connecting plate is further connected with at least one of nut bases; and openings of the nut bases face the outside. The multi-nut base assembly type pull-resistant joint has the advantages that a connecting mode between two pull-resistant piles can be changed, and a connecting place between the two pull-resistant piles can not be damaged by underground water, so that the tensile strength and the bend strength between two end plates can be improved, therefore, the performance of the whole pile can be improved.
Description
Technical field
The utility model 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, can produce the pile extension phenomenon because of multiple factor; Most applications is to utilize the weldability of pile body metal end plate after pile body aligns, two end plates to be welded with electric welding in the pile body connection procedure; Be generally speaking regional buoyancy force of underground water no problem but that have because of the multiple phenomenon of geological condition big with underground water destructive strong to solder side, this kind can not reach the architectural design requirement by the electric welding method of attachment.
The utility model content
The utility model purpose: in order to overcome the deficiency of prior art, the purpose of the utility model 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 scheme that the utility model adopted is: a kind of many nut seats assembling resistance to plucking joint; Comprise square endplate; And be close to two nut seats that are provided with on each limit at the end plate back side, and be connected with anti-rotation junction plate between adjacent two nut seats on the adjacent both sides, be connected with of said anti-rotation junction plate on the limit of nut seat and also be connected with at least one nut seat; The opening of all nut seats all outwardly.
The nut seat that is located on same one side of said 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 through anti-rotation junction plate.
In order to save production cost, the nut seat that is located on same one side of said anti-rotation junction plate has two.
Said anti-rotation junction plate is that angle is 90 ° the anti-rotation junction plate of L type.Go into 90 degree angles, strengthened when assembling bolt to the turning moment of nut.
Beneficial effect: compared with prior art; The utility model has the advantages that: 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 whole stake.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the assembling drawing of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
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 are provided with on each limit at end plate 1 back side, and being connected with anti-rotation junction plate 3 between adjacent two nut seats 2 on the adjacent both sides, in anti-rotation junction plate 3 one has been connected with on the limit of nut seat 2 and also has been connected with at least one nut seat 2; The opening of all nut seats 2 all outwardly, anti-rotation junction plate 3 is that angle is 90 ° the anti-rotation junction plate 3 of L type, and the two ends of anti-rotation junction plate 3 are welded on the bottom of nut seat 2 respectively.
The nut seat 2 that is 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; Explain that pulling test strength is high more; But consider that from the aspect that saves production cost the nut seat 2 that is located on same one side of anti-rotation junction plate 3 has two, and two can have been satisfied pulling test strength and required.
The two ends of anti-rotation junction plate 3 are welded on the bottom of adjacent two nut seats 2 on the adjacent both sides through the mode of electric welding; In anti-rotation junction plate 3 one has been welded with on the limit of a nut seat 2 and has welded a nut seat 2 more then; Concreting then; Nut seat 2, anti-rotation junction plate 3 all in concrete structure, so just can make this junction plate place fully and not receive phreatic destruction in the concrete structure, thereby satisfy the architectural design requirement like this.
Shown in Figure 3 is the assembling drawing of two uplift piles; During assembling; The nut seat 2 that at first will go up on the pile body is placed with nut seat 2 symmetries on the following pile body; End plate 1 and the end plate 1 of following pile body that to go up then on the pile body weld together, and installation junction plate 4 on the symmetrical nut seat 2 of last pile body and following pile body again passes with bolt 5 respectively at last that junction plate 4 will be gone up pile body and following pile body is assembled together; So just can improve the tensile strength and the flexural strength of 1 of two end plate, thereby improve the performance of whole stake.What bolt 5 adopted is that diameter is the bolt of M18; The bolt of 12 M18 is arranged on the last pile body, down the bolt of 12 M18 is arranged equally on the pile body, the high-strength bolt that is M18 by 24 specifications when assembling like this fixes, and wherein the shearing resistance of every on the bolt of M18 is 110KN; 24 shearing resistance 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 utility model to assemble, and shearing resistance is apparently higher than national standard.
