Description
Technical Field
The utility model relates to a bored concrete pile steel reinforcement cage hoist and mount technical field, in particular to bored concrete pile steel reinforcement cage positioner.
Background
The cast-in-place concrete pile has the advantages of low noise, small vibration, small influence on the environment, adjustable diameter of the pile body, high bearing capacity of the pile body and strong shearing strength during construction, so that the cast-in-place concrete pile is widely applied to high-rise buildings, large bridges, deepwater wharfs, offshore oil drilling platforms and the like. In the cast-in-place pile construction process, whether the steel reinforcement cage is centered directly influences the thickness of a protective layer, and even some supporting piles have the condition that steel reinforcements are exposed after excavation, the durability of the cast-in-place pile is seriously influenced, so whether the steel reinforcement cage is centered is an important influence factor of whether the cast-in-place pile can meet the designed load requirement.
The traditional reinforcement cage positioning method comprises the following steps: the method comprises the steps of pulling a cross line on a reinforcement cage, finding out the center of the reinforcement cage, finding out the center of a pile position according to a pile casing, inserting two parallel square steel bars below a top hanging ring at the top end of a positioning reinforcement cage, placing two parallel sleepers on two sides of the pile casing, and supporting the square steel bars on the sleepers to enable the center of the reinforcement cage to be coincident with the center of the pile position. The method only ensures that the center of the upper part of the reinforcement cage coincides with the center of the pile at the time, but the problem that the reinforcement cage inclines or touches the side wall can occur when the guide pipe is inserted for pouring concrete in the later period of pouring concrete, and the center of the reinforcement cage and the center of the pile cannot be ensured to be on the same straight line, so that the bearing capacity of the pile foundation is influenced, and meanwhile, the thickness of the protective layer of the reinforcement cage cannot be ensured, and the durability of the pile foundation is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a bored concrete pile steel reinforcement cage location centering device mainly solves the problem of bored concrete pile steel reinforcement cage hoist and mount to the in-process steel reinforcement cage location of accomplishing the back.
The utility model discloses a simple easy site operation preparation can be according to steel reinforcement cage positioner who tears open, reuse fast.
The utility model provides a bored concrete pile steel reinforcement cage location centering device, comprises two arc steel sheets, threaded rod, nut, the gasket that have the screw hole, and an arc steel sheet arc length is 15cm, and another arc steel sheet arc length is 20cm, and threaded rod one end is welded with the arc steel sheet that the arc length is 20cm, and the threaded rod other end passes steel reinforcement cage, protects a section of thick bamboo and the arc steel sheet that the arc length is 20cm and fastens with the nut.
The height of the two arc-shaped steel plates is 30cm, and the thickness of the two arc-shaped steel plates is 2 cm.
The threaded rod length is 25cm and the rubber ring washer diameter is 80 mm.
Adopt 3 groups the same the utility model discloses become 120 degrees and place and fix a position the steel reinforcement cage. Be about for 3 pump utility model settings inboard and protect between the section of thick bamboo outside and protect a section of thick bamboo with the steel reinforcement cage and fix. Through adjusting three nut, remove every group the utility model discloses the relative distance of well two steel sheets, and then the position of removal steel reinforcement cage makes steel reinforcement cage center and pile position center coincidence and fixed steel reinforcement cage.
The utility model discloses light in weight, simple structure, installation, dismantlement convenience, reuse, but wide application drilling concrete bored concrete pile construction field.
Drawings
Fig. 1 is a usage state diagram of the present invention.
In the figure, 1, a large steel plate, 2, a small steel plate, 3, a nut, 4, a threaded rod, 5, a protective cylinder, 6, a reinforcement cage, 7 and a positioning reinforcement.
Detailed Description
Example (b): fig. 1 shows that the utility model is composed of a big steel plate 1, a small steel plate 2, a threaded rod 4, a nut 3 and a gasket. Wherein the threaded rod 4 is welded in the middle of the back surface of the large steel plate 1, and the threaded hole is arranged in the middle of the small steel plate 2.
The large steel plate 1 is arc-shaped, the arc length is 20cm, the height is 30cm, and the thickness is 2 cm.
The small steel plate 2 is arc-shaped, the arc length is 15cm, the height is 30cm, and the thickness is 2 cm.
The threaded rod length is 25cm and the rubber ring gasket outer diameter is 80 mm.
The utility model discloses a use method: after the hoisting of the cast-in-place pile reinforcement cage is completed, two parallel square steel bars are inserted below a top hanging ring at the top end of the framework of the positioning steel bar 7, and two parallel sleepers are placed on two sides of the pile casing 5.
The large steel plate 1 and the threaded rod 4 of the utility model are extended into the inner side of the reinforcement cage 6, and the threaded rod 4 passes through the wall of the reinforcement cage and the wall of the pile casing and extends out of the outer side of the pile casing 5;
the small steel plate 2 is screwed on the threaded rod 4 and the washer is padded with the nut 3.
The other two sets of the same reason installation the utility model discloses, and with a set of in same level that has installed and become 120 degrees angles respectively.
At last, draw the cross wire on the steel reinforcement cage, find out the steel reinforcement cage center, find out stake position center according to protecting a section of thick bamboo, whether inspection steel reinforcement cage central point puts and coincides with stake position center, if the coincidence, it is qualified to explain steel reinforcement cage hoist and mount, needn't adjust the utility model discloses, direct fastening nut can. If deviation exists, the reinforcing cage needs to be forced to be centered and then fixed through adjusting the nuts of a certain group of positioning devices on the pile casing.
