Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
The positioner of bored concrete pile spiral stirrup in this embodiment is that the welding of cooperation bored concrete pile spiral stirrup 2 uses, and this positioner of bored concrete pile spiral stirrup can fix a position around establishing spiral stirrup 2 outside steel reinforcement cage owner muscle 1, so fix a position the interval between spiral stirrup 2 to fix spiral stirrup 2 for steel reinforcement cage owner muscle 1's position, make things convenient for constructor to carry out the weldment work of spiral stirrup 2 on steel reinforcement cage owner muscle 1. The positioning device for the spiral stirrups of the cast-in-situ bored pile can facilitate independent and convenient work of constructors, and the input constructors are few and the working efficiency is high.
As shown in fig. 1 and fig. 2, the positioning device for a spiral stirrup of a cast-in-situ bored pile in the present embodiment includes a positioning rod 3 and a positioning member 4.
Wherein setting element 4 is provided with at least two, and setting element 4 is provided with a plurality ofly usually, and setting element 4 distributes along the axial of locating lever 3 and sets up to each setting element 4 is connected on locating lever 3 according to 2 interval requirements of spiral stirrup. The positioning member 4 in this embodiment is fixedly connected to the positioning rod 3. In order to improve the applicability of the positioning device for the spiral stirrup of the bored pile, the positioning element 4 can also slide and be connected to the positioning rod 3 in a positioning manner, if the positioning element 4 can be arranged on a hoop, the hoop is sleeved on the positioning rod 3, and the hoop is provided with a tightening screw to realize the sliding and fixing of the positioning element 4 relative to the positioning rod 3. The fixing position of the positioning piece 4 on the positioning rod 3 can be adjusted according to different distances between the spiral stirrups 2.
Each positioning piece 4 comprises two positioning legs 41 extending along the radial direction of the positioning rod 3, and an included angle is formed between the two positioning legs 41; or the positioning piece 4 is a rod body which is gradually and obliquely arranged upwards from the connecting position on the positioning rod 3. The free ends of the positioning legs 41 and the rod body are connected with a limiting piece 42. The structure is simple, and the positioning leg 41 and the free end of the rod body are bent upwards to form the limiting part 42. The positioning element 4 in this embodiment adopts a scheme including two positioning legs 41, and an included angle between the two positioning legs 41 is 60 °.
During the use, locating lever 3 is connected on steel reinforcement cage owner muscle 1 along the extending direction of steel reinforcement cage owner muscle 1, and in this embodiment, the both ends of locating lever 3 are provided with a buckle 5 respectively, so locating lever 3 then through 5 firm fixes on steel reinforcement cage owner muscle 1 of buckle. The buckle 5 in this embodiment sets up towards 1 opening of steel reinforcement cage owner muscle, and location foot 41 also extends to 1 direction of steel reinforcement cage owner muscle. Buckle 5 in this embodiment adopts spring buckle 5 to the dismouting on steel reinforcement cage owner muscle 1 is conveniently realized.
The locating lever 3 in this embodiment adopts hollow stainless steel pipe or plastic steel pole that the external diameter is 25mm, length is 110cm, and buckle 5 sets up in the 5cm department apart from 3 ends of locating lever, so make locating lever 3 go up to have the clear distance of 1m and be used for setting up setting element 4, generally require that the interval of spiral stirrup 2 equals, in the clear distance scope of two buckle 5 of locating lever 3 in this embodiment, every interval 20cm sets up a setting element 4.
The use method of the positioning device for the spiral stirrup of the cast-in-situ bored pile comprises the following steps: install the positioner of two this bored concrete pile spiral stirrups on steel reinforcement cage owner muscle 1 after the equipment, the positioner of these two bored concrete pile spiral stirrups is installed on 1 radial two relative owner muscle of steel reinforcement cage owner muscle, fixes through buckle 5. Because spiral stirrup 2 is the heliciform winding outside steel reinforcement cage owner muscle 1, then need be installed two drilling bored concrete pile spiral stirrup's positioner to be certain difference in height to satisfy spiral stirrup 2's spiral trend. After the positioning rods 3 of the positioning devices for the spiral stirrups of the two cast-in-situ bored piles in the embodiment are fixed on the main reinforcement, the height difference between the bottom ends of the two positioning rods 3 is 10 cm. Then the spiral stirrup 2 is clamped into the positioning member 4 in a layered manner, and under the action of the limiting member 42, the spiral stirrup 2 can be positioned on the positioning member 4 well and cannot fall off from the positioning member 4. After each layer of spiral stirrup 2 is all fixed on the setting element 4, then the interval of spiral stirrup 2 has kept unanimous, has satisfied the design interval requirement, and at this moment, constructor carries out the weldment work of spiral stirrup 2 on the main muscle can. After the spiral stirrup 2 after the location is welded, the positioning device of the spiral stirrup of the cast-in-situ bored pile is taken down from the steel reinforcement cage main reinforcement 1, and then the positioning device of the spiral stirrup of the cast-in-situ bored pile is fixed in position, and the work is repeatedly carried out until the spiral stirrup 2 completely completes the welding work. The construction process has the advantages of less manpower input and high construction efficiency.
