Abstract
A concrete prefabricated square pile connector comprises an upper pile (1) and a lower pile (3). The concrete prefabricated square pile connector is characterized in that a concave structure (2) is arranged at the lower end of the upper pile (1), an upper convex structure (4) which is matched with the concave structure (2) is arranged on the upper portion of the lower pile (1), and the upper convex structure (4) is inserted into the concave structure (2) and connected with the concave structure (2) through a connector bolt (5). On the basis that existing pile manufacturing technology and constructing technology are not changed, the concrete prefabricated square pile connector is capable of greatly improving pile connecting efficiency, at the same time, avoids accident potential caused by welding and the requirements to the technological level of a welding operator, and has the advantages of being low in pile connecting cost and good in pile connecting quality.
Description
Technical field
The utility model relates to a kind of constructional materials, especially a kind of building foundation pilework, specifically a kind of concrete prefabricated side's pile joint of hollow joint.
Background technology
As everyone knows, concrete prefabricated side's stake is used widely because of advantages such as its steady quality, easy constructions.During piling, the bad or reason such as stake long deficiency etc. because of geological conditions can occur, the sharp position of stake does not reach bearing stratum depth, just need carry out pile extension in this case.Traditional pile extension mode mostly adopts artificial welding, and welding quality influences by human factor and weather condition, and weldquality is difficult to control, wastes time and energy, and tensile property also is difficult to guarantee fully simultaneously, and then has influence on the quality of whole construction engineering.
Summary of the invention
The purpose of this utility model is the problem that connects inconvenience at the stake of existing hollow side, designs a kind of concrete prefabricated side's stake snap joint easy to connect, to improve pile extension efficient and the quality in the pile extension process.
The technical solution of the utility model is:
A kind of concrete prefabricated side's pile joint, it comprises stake 1 and following 3, it is characterized in that described lower end of going up stake 1 is provided with concave inward structure 2, described following 1 top is provided with the convex configuration 4 that matches with described concave inward structure 2, and described convex configuration 4 is inserted in the described concave inward structure 2 and by track bolt 5 and connected.
The quantity of described track bolt 5 is at least two in each face and evenly arranges.
The beneficial effects of the utility model:
The utility model is on the basis that does not change existing system stake and construction technology, can increase substantially pile extension efficient, avoided accident potential that welding causes simultaneously and to the requirement of welding operating personnel technical level, and it is low to have a pile extension cost, pile extension matter measured advantage.
The utility model is simple in structure, and the integral rigidity of the stake that is formed by connecting is strong, and polarization is good, is easy to assembly unit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the lateral view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of concrete prefabricated side's pile joint, it comprises stake 1 and following 3, described lower end of going up stake 1 is provided with the concave inward structure 2 that the elasticity steel are made, this concave inward structure 2 can be in advance with last stake 1 on main reinforcement be weldingly connected to guarantee concave inward structure and last bonding strength, described following 1 top is provided with the convex configuration 4 that matches with described concave inward structure 2, convex configuration 4 also can adopt the manufacturing of elasticity steel, it also can be weldingly connected to guarantee bonding strength with a following reinforcing bar in the time of prefabricated following in advance, described convex configuration 4 is inserted in the described concave inward structure 2 and by track bolt 5 and is connected, as shown in Figure 1.For the bonding strength of stake on improving with following, the quantity of the track bolt 5 on each joint face is at least 2, and be evenly arranged on each face, for easy to connect, the site error of the bolt hole that is used for spinning track bolt 56 on each concave inward structure 2 and the convex configuration 4 should strict control.
During operation, at first adjust to go up the position of stake, the axis that makes stake coincides with following axis as far as possible, slowly moves to the position that contacts in adjustments, when last during with following fastening, illustrates that the preformed pile pile extension finishes, and can fix with track bolt.In actual engineering, the quantity of bolt and shape can be adjusted according to the precast square pile feature, such as can every side arranging 3 bolts.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
Claims (3)
1. concrete prefabricated side's pile joint, it comprises stake (1) and following (3), it is characterized in that described lower end of going up stake (1) is provided with concave inward structure (2), the top of described following (1) is provided with the convex configuration (4) that matches with described concave inward structure (2), and described convex configuration (4) is inserted in the described concave inward structure (2) and by track bolt (5) and connected.
2. concrete prefabricated side's pile joint according to claim 1 is characterized in that the quantity of described track bolt (5) is at least two in each face and even the layout.
