Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pretensioning prestressed high performance concrete pipe pile, concretely to a structure of pretensioning prestressed high performance concrete pipe pile. BACKGROUND

[0002] Pretensioning is to tension the prestressed tendon before pouring concrete, and the tensioned prestressed tendon is temporarily anchored on the pedestal or steel mold, then the concrete is poured, and when the concrete curing reaches not less than 75% of the design strength value of the concrete, the prestressed tendon is loosened, and the concrete is applied with prestress by the adhesion of the concrete and the prestressed tendon. Pretensioned concrete refers to the improvement of the crack resistance of reinforced concrete members, but in the existing concrete pipe column, the pipe column needs to be lifted and transported by a crane, and the pipe column is unstable when the position is changed, which causes the external collision damage of the pipe column. The existing connecting seat installation is relatively single, and the pipe column itself has a certain weight, which is prone to falling phenomenon. In order to avoid such things, a connecting seat with double installation connection is specially designed to ensure that the pretensioning prestressed high performance concrete pipe pile is in a stable state when being lifted.

The structure of the pretensioning prestressed high performance concrete pipe pile avoids the sliding of the lifting ring group outside the lifting appliance, thereby causing the pipe pile to shake, avoids the collision between the shaking pipe pile and the external object, which can cause the pipe pile to break, prevents the reduction of the service life of the pipe pile, causes the pipe pile to be damaged and unable to be used, avoids the dust adhering to the outside of the bidirectional screw rod, thereby affecting the normal transmission of the bidirectional screw rod, and avoids the bidirectional screw rod unable to drive the C-shaped ring fixed outside the lifting appliance.

[0004] The prior art in the above has the following defects: it is inconvenient to limit the lifting rope when the pretensioning prestressed high performance concrete pipe pile is lifted, and it is impossible to avoid the left and right movement causing the pipe column to collide and damage, it is inconvenient to adjust the position of the limiting device, and it is inconvenient to double install and limit the concrete pipe pile. Therefore, the utility model provides a structure of pretensioning prestressed high performance concrete pipe pile to solve the problems mentioned above. UTILITY MODEL CONTENTS

[0012] Preferably, the middle part of the sliding bolt is in a bonded state with the spring, and the sliding bolt, the spring and the fourth nut are symmetrically arranged about the center line of the first arc plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the structure of the pre-tensioned prestressed high-performance concrete pipe pile facilitates the lifting rope to be limited when the pre-tensioned prestressed high-performance concrete pipe pile is lifted, avoiding collision damage to the pipe column caused by left and right movement, and facilitating the adjustment of the position of the limiting device, and facilitating the double installation limiting of the concrete pipe pile.

[0014] 1. Equipped with a bidirectional threaded rod, a first clamping arm, and a second clamping arm, when the pre-tensioned high-performance concrete pipe pile structure is in use, the connecting seat body is installed at both ends of the concrete pipe pile group through fixing bolts and the first nut. When the concrete pipe pile needs to be moved, when the lifting device of the crane is placed on the left and right sides of the concrete pipe pile, the lifting rope connected to the lifting device is placed in the middle of the first clamping arm and the second clamping arm. At this time, the motor is started and the first clamping arm and the second clamping arm are driven to move towards the middle through the bidirectional threaded rod, so that the first clamping arm and the second clamping arm limit the lifting rope and prevent the lifting rope from swaying left and right. When lifting the pre-tensioned high-performance concrete pipe pile, the lifting rope is limited to avoid collision damage to the pipe pile caused by left and right movement.

[0015] 2. Equipped with a second bolt, a third nut, and a second arc-shaped plate, when the first and second arc-shaped plates need to be attached to the front and rear sides of the concrete pipe column assembly, since the concrete pipe column assemblies are of different sizes, the second nut and the third nut need to be rotated respectively to adjust the position of the second bolt inside the left end of the fixing rod, thereby driving the first and second arc-shaped plates to be attached to the inner wall of the concrete pipe column assembly, ensuring that they can be stably connected, and facilitating the adjustment of the position of the limiting device;

[0016] 3. Equipped with sliding bolts, springs, and a fourth nut, when multiple stable installations of the connecting seat body are required, the connecting seat body is first installed and limited by the fixing bolts and the first nut. However, when the lifting device is lifted, the weight of the pipe column itself can easily cause it to detach. At this time, the connecting seat body is stabilized a second time by the first and second arc-shaped plates on the left side. When the first and second arc-shaped plates are driven to fit the width of the pipe column, they are stabilized inside the first and second arc-shaped plates. After clamping and limiting, the sliding bolt is slid backward to compress the spring, so that the sliding bolt passes through the slots at both ends of the second arc-shaped plate. The fourth nut is used to connect to the rear end of the sliding bolt, thus fixing the first and second arc-shaped plates in place, which facilitates double installation and limiting of the concrete pipe pile.
