Abstract

The utility model discloses a fast connector for a steel reinforced concrete precast pile. The utility model is characterized in that the end head of a pile body is provided with a fixing hoop, a sliding block with teeth is arranged in a connecting groove which is arranged on the fixing hoop, the sliding block is correspondingly connected in the pile body, the tooth directions of the connecting teeth on the sliding block are opposite, a connecting pin is inserted in the connecting groove, and engagement teeth on the connecting pin are engaged with the connecting teeth to connect two sections of pile bodies. The utility model has the advantages of simple structure, low cost and construction efficiency enhancement.

Description

Precast reinforced concrete piles snap joint

The utility model relates to a kind of in order to connect the snap joint of two joint precast reinforced concrete piles.

The job practices that is used for the connecting reinforcement concrete precast pile has multiple, such as: the welding of steel plate angle steel, the sulphide mastic anchoring is fixed, and mechanical type pile extension method.Steel plate angle steel welding, waste steel and work efficiency are low, and sulphide mastic anchoring method is not suitable for pile tube again plugs into, and the mechanical type pile extension consumes great deal of steel owing to needs, construction cost is higher.

The purpose of this utility model is a kind of simple in structure in order to provide, and cost is low, and can effectively improve the precast reinforced concrete piles snap joint of construction efficiency,

Main technical schemes of the present utility model is: on the termination of pile body clips is installed; Have a plurality of link slots in the clips, slide block one side that is contained in the link slot has the connection tooth, and opposite side is near the push rod of being pressed by spring; On the slide block in two link slots that connect, the teeth directional that connects tooth is opposite, and connecting pin inserts in the link slot, have on it opposite engaging tooth of two sections teeth directionals respectively with slide block on be connected the tooth engagement, two joint pile bodies are linked to each other.

When construction, earlier connecting pin is inserted in the link slot that saves preformed pile down, will go up the link slot of joint preformed pile then and depress over against connecting pin, make upper and lower two joint preformed pile butt joints.The utility model construction technology is simple, and it is fast to plug into, and each joint is saved 0.1 machine-team than traditional welding point method, and because part processing is also very simple, greatly reduces cost of production on the whole.The utility model sound construction can bear and transmit the frictional force and shearing force and because the eccentric moment of flexure that produces that produce in the piling process.

Fig. 3 is the A-A sectional view of Fig. 2;

Fig. 4 is the partial structurtes schematic diagram of 3 (3 ') part after upper and lower joint stake is plugged into.

As Fig. 1, Fig. 2, shown in Figure 3, structure of the present utility model is: on the pile body 1 of up and down 2-section pipe stake, 1 ' termination clips 2,2 ' is installed, evenly offer 8 link slots 3,3 ' in the clips 2,2 ', the link slot number can suitably increase and decrease according to actual needs.As shown in Figure 4, be contained in link slot 3,3 ' interior slide block 4,4 ' one sides have connect tooth 5,5 ', opposite side near by the push rod 7,7 of spring 6,6 ' pressing ', the slide block 4,4 of two link slots 3,3 that connect ' interior ' on, connect tooth 5,5 ' teeth directional opposite, connecting pin 8 insertion link slots 3,3 ' in, promote earlier slide block 4,4 ' after move, when the engaging tooth on the connecting pin 9,9 ' with slide block 4 ' on be connected tooth 5,5 ' over against after, spring promotion push rod 7,7 ', slide block 4,4 ' reach makes engaging tooth and is connected the tooth interlock.For cooperating with the slide blocks of two joints in the pile bodies, the engaging tooth 9,9 on the connecting pin ' teeth directional also be opposite.In order to improve the sealing performance of joint, be filled with fluid sealant at the between cog that is meshed, can also prevent that like this stake from reaching vertical direction in the horizontal direction and producing displacement.

Claims (3)

1. precast reinforced concrete piles snap joint, it is characterized in that: last, two save pile bodies (1) down, clips (2) is installed on the termination of (1 '), (2 '), clips (2), have a plurality of link slots (3) in (2 '), (3 '), be contained in link slot (3), slide block (4) in (3 '), (4 ') side has connection tooth (5), (5 '), opposite side is near by spring (6), the push rod that is pressing (6 ') (7), (7 '), two link slots (3) that connect, slide block (4) in (3 '), (4 ') are gone up and are connected tooth (5), the teeth directional of (5 ') is opposite, connecting pin (8) inserts in the link slot, two sections engaging tooths (9) that teeth directional is opposite are arranged on it, (9 ') respectively with slide block (4), connection tooth (5) on (4 '), (5 ') engagement links to each other two joint pile bodies.
