Definitions
- the invention relates to a quick joint for connecting two sections of reinforced concrete prefabricated piles.
- the object of the present invention is to provide a quick joint of a steel reinforced concrete prefabricated pile which has a simple structure, low cost, and can effectively improve construction efficiency.
- the main technical solution of the present invention is as follows: a fixing hoop is installed on the end of the pile body; a plurality of connecting grooves are opened in the fixing hoop, the slider installed in the connecting groove has connecting teeth on one side, and the other side is close to the A spring-loaded push rod; on the sliders in the two opposite connecting grooves, the teeth of the connecting teeth are opposite, and the connecting pin is inserted into the connecting groove, and there are two segments of oppositely engaging teeth that are opposite to the slider The connecting teeth on the meshing link the two piles together.
- the connecting pin is first inserted into the connecting groove of the lower precast pile, and then the connecting groove of the upper precast pile is directly pressed against the connecting pin, so that the upper and lower prefabricated piles are docked.
- the construction process of the present invention is simple. Faster connection, each joint saves 0.1 shifts compared with the traditional welding joint method, and because the part processing is also simple, the production cost is greatly reduced as a whole.
- the invention has a firm structure, and can withstand and transmit the frictional force and shearing force generated during the driving process and the bending moment due to eccentricity.
- Figure 1 is a schematic diagram of the connection of upper and lower piles
- FIG. 2 is a schematic top plan view of an embodiment of the present invention.
- FIG. 3 is a cross-sectional view taken along AA of FIG. 2.
- Fig. 4 is a partial structure diagram of part 3 (3 ') after the connection of the upper and lower piles.
- the structure of the present invention is as follows: Fixed ends 2 and 2 'are installed on the ends of the fixed ends. Eight fixed connecting slots 3 and 3' are evenly arranged in the fixed ends 2 and 2 '. The number of connecting slots can be appropriately increased or decreased according to actual needs. Sliders in connection slots 3, 3 '
- the spring pushes the push rod 7, 7 ', and the sliders 4, 4' move forward to engage the engaging teeth with the connecting teeth.
- the tooth directions of the engaging teeth 9, 9 'on the connecting pin are also reversed.
- a sealant is filled between the meshing teeth, which can also prevent the pile from being displaced in the horizontal and vertical directions.
