Embodiment 1

[0026] A column-type abutment with pile-connected steel bars without support, which consists of: a pile head 1, the pile head has a pile head steel bar 2, the pile head steel bar is located inside the pile head, and the pile head The reinforcing bars are set upright, and a set of reinforcing hoops 3 is arranged on the pile head, the pile head reinforcement fits the pier body main reinforcement 4, and the pile head reinforcement and the pier body main reinforcement pass through a fixing piece 5 is fixed, and the outer fixing part 6 is used to fix between the reinforcing stirrup circle and the main bar of the pier body.

[0027] The fixing part can connect and fix the pile head steel bar and the main bar of the pier body together, (welding connection can also be adopted) when fixing is simple and firm, and the use effect is good.

[0028] The external fixing part can connect and fix the main reinforcement of the pier body and the reinforcing hoop ring together. (Welding connecti...

Embodiment 2

[0030] The column-type abutment piling reinforcement described in Example 1 has no support, and the fixing member includes an elastic split ring 7, and a round hole 8 is opened at one end of the elastic split ring, and the other end of the elastic split ring Fixedly connect the plunger 9, the elastic split ring covers the pile head steel bar and the main reinforcement of the pier body, the plunger passes through the round hole, the plunger has a threaded section, the The threaded section is located above the round hole, the threaded section is connected to the screw nut 10, the left side of the screwed nut has a left screwed wing 11, and the right side of the nut has a right screwed wing 12. Screw the left screw wing and the right screw wing to fasten the screw nut.

[0031] When screwing the screw nut, it is labor-saving due to the effect of the left screw wing and the right screw wing, and upper force can be used.

Embodiment 3

[0033] The column-type abutment piling reinforcement described in Embodiment 1 has no support, and the external fixing member includes a fixing plate 13, and the fixing plate has an upper left fixing slat 14, a lower left fixing slat 15, and an upper right fixing slat 16 , the lower right fixed slat 17, the described fixed plate, the described upper left fixed slat, the described lower left fixed slat, the described upper right fixed slat, the described lower right fixed slat are integrated structure, The upper left fixed slat is used in conjunction with the lower right fixed slat, and the lower left fixed slat is used in conjunction with the upper right fixed slat.

Abstract

The invention discloses a scaffolding-free structure connecting a column pier and abutment to pile reinforcing bars and a construction method. The scaffolding-free structure comprises a pile head, wherein the pile head is provided with pile head reinforcing bars; the pile head reinforcing bars are positioned inside the pile head; the pile head reinforcing bars are arranged vertically; the pile head is provided with a strengthening stirrup ring; the pile head reinforcing bars are attached to pier shaft main bars; the pile head reinforcing bars and the pier shaft main bars are fixed by fixing parts or by tying; and the strengthening stirrup ring and the pier shaft main bars are fixed by external fixing parts or by tying. The scaffolding-free structure is used for the bridge pier shaft reinforcing bar construction.

Description

Technical field: [0001] The invention relates to a column-type pier abutment with pile-connected steel bars without support and a construction method. Background technique: [0002] For the substructure of bridges without caps directly connected between the pier body and the pile foundation, after the pouring pile foundation concrete is poured and the pile head is removed, the connection construction between the pier body reinforcement and the pile foundation reinforcement should be carried out. In the case of a crane, the steel bars of the pier body can be pre-processed into a barrel-shaped skeleton, and then hoisted and installed. This method requires lifting equipment, and the second is that the quality of the connection between the pier body steel bars and the pile body is difficult to control, and it is difficult to fully achieve requirements. In the absence of hoisting equipment, it is generally necessary to set up scaffolding to bind the steel bars of the pier body. ...
