Description

Technical Field

[0001] The invention relates to the technical field of building construction equipment, in particular to a pile cap for hammered piles in pipe pile construction. Background Art

[0002] In construction projects, hammering is often used in pipe pile construction. The pile cap is an important component in the construction process of hammered piles. Its function is to evenly transfer the impact force of the pile hammer to the top of the pipe pile to prevent the top of the pipe pile from being damaged due to excessive local force.

[0003] In the prior art, such as the patent application number: CN202022990622.7, "A pipe pile cap suitable for hammer pile construction", the top of the pile cap is a circular steel plate with an exhaust hole in the center. The circular steel plate is welded concentrically with the inner and outer steel ring guard plates at its lower part. The stiffening steel ribs support and reinforce the circular steel plate and the steel ring guard plates. The outer stiffening steel ribs are provided with hanging holes. A steel fiber rubber annular gasket is provided in the annular groove between the inner and outer steel ring guard plates. The pipe pile cap of the utility model can play a buffering role in the process of hammer pile construction, so that the top of the pipe pile is evenly stressed and the pile body is prevented from tilting. The pile cap itself has a strong impact resistance, and it also solves the problem that the pile body is easily damaged during the construction of hammer pile.

[0004] The existing hammer piles are prone to pile head explosion due to excessive impact force when hammering the piles, which in turn causes the pile head to be unable to be used normally, affecting the operation effect. To address the above problems, a pile cap for hammer pile construction is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a pile cap for hammer piles in pipe pile construction, so as to solve the problem that in the prior art operation proposed by the above background technology, the pile head may explode due to excessive impact force when the hammer pile is hammered, thereby causing the pile head to be unable to be used normally and affecting the operation effect.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pile cap of a hammer pile in pipe pile construction, comprising a pile cap mechanism, a clamping mechanism is arranged at the bottom and the outer side of the pile cap mechanism, the pile cap mechanism comprises a hammer pile cap, a top cover is arranged at the top of the hammer pile cap, a steel plate is arranged inside the hammer pile cap, a reinforcing pad is arranged at the bottom of the steel plate, an inner support plate is arranged at the bottom of the reinforcing pad, and hard rubber is arranged at the bottom of the inner support plate, the reinforcing pad and the inner support plate are both connected to the inner side of the hammer pile cap, screw holes are opened through both sides of the hammer pile cap, a through hole is opened at the bottom of the hammer pile cap, the hammer pile cap is sleeved on the top of the pile, and a hard rubber is arranged at the connection between the inside of the hammer pile cap and the top of the pile. The rubber is used as a flexible support, and the inner support plate is further installed on the top to keep it stable. In addition, the top cover is used to seal the top for easy hammering. At the same time, the use of steel plates and reinforcing pads is conducive to increasing the support force and strength inside, thereby ensuring the use effect. The pile cap can transfer this concentrated impact force to the pile top more evenly. The pile cap is usually equipped with buffer materials. These buffer materials will undergo elastic deformation when impacted, making the impact force more evenly distributed on the pile top, avoiding the pile top from being broken, crushed, and damaged due to excessive local force. The pile cap can effectively reduce the occurrence of such deformation through its own structural strength and buffer mechanism. The pile cap is usually equipped with a centering device to ensure that the pile cap is accurately aligned with the pile top. In the process of pile sinking, centering is very critical. If the pile cap is not aligned with the pile top, eccentric force will be generated when hammering. The centering device of the pile cap can adapt to piles of different diameters, so that it can be accurately positioned at the center of the pile top, ensuring that the hammer force acts vertically on the pile top, thereby ensuring that the direction of pile sinking is vertical, meeting the project's requirements for the verticality of the pile foundation. When the pile hammer hits the pile top, the pile body will generate a reaction force. The pile cap can buffer the damage to the pile hammer caused by this reaction force. The buffer device in the pile cap will produce elastic deformation when subjected to the reaction force of the pile body, absorbing part of the energy, thereby reducing the impact of the reaction force on the pile hammer and extending the service life of the pile hammer.

[0007] Preferably, the clamping mechanism includes a first rotating seat, a clamping plate and a clamping ring, the first rotating seat is symmetrically connected to the outer wall of the hammer pile cap, the inner side of the first rotating seat is movably connected to a pneumatic telescopic rod, and the pneumatic telescopic rod is rotatably connected to the first rotating seat, which facilitates the installation of the pneumatic telescopic rod and provides a pneumatic telescopic adjustment function, thereby facilitating the simultaneous rotation and adjustment of the second rotating seat.

[0008] Preferably, one end of the pneumatic telescopic rod is movably connected to a second rotating seat, the bottom end of the second rotating seat is connected to a connecting plate, one end of the connecting plate is fixedly connected to a connecting block, and side support bars are symmetrically fixedly installed on one side of the connecting plate and the connecting block. The connecting plate is driven to rotate by controlling the extension and retraction of the pneumatic telescopic rod, which is beneficial to drive the connecting block to rotate and adjust, thereby achieving the effect of high-efficiency transmission, wherein the side support bars can provide stable supporting force to ensure stable clamping.

[0009] Preferably, one end of the connecting block is movably connected to a third rotating seat, and the side surface of the third rotating seat is fixedly connected to the outer side of the hammer pile cap. The third rotating seat facilitates the rotation and support of the connecting block, thereby improving stability.

[0010] Preferably, the other end of the connecting block is movably connected to a fourth rotating seat, and the side of the fourth rotating seat is fixedly connected to an inclined plate. The fourth rotating seat facilitates the connection between the connecting block and the inclined plate, thereby achieving quick and convenient operation.

[0011] Preferably, the outer wall of the inclined plate is provided with a threaded thread opening, and the outer side of the inclined plate is sleeved with a fastening ring. The inner wall of the fastening ring is threadedly connected to the threaded thread opening. Through the connection between the threaded thread opening and the fastening ring, the inclined plate and the threaded thread opening are distributed in an oblique inverted trapezoidal shape, which is conducive to providing further fastening effect and ensuring stability.

[0012] Preferably, the clamping plate is arranged on the inner side of the inclined plate, and a plurality of anti-slip strips are evenly distributed on the inner side of the clamping plate. The anti-slip strips are distributed inside the clamping plate to provide an efficient protective treatment effect to ensure stability after clamping.

[0013] Preferably, the bottom of the clamping ring is fixedly connected to the top of the clamping plate, and a plurality of anti-slip rings are evenly distributed on the inner side of the clamping ring. The distribution of the anti-slip rings on the clamping ring is beneficial to provide further stable anti-slip limiting effect after the clamping ring is clamped.

[0014] Preferably, the height of the hammer pile cap is 41-45 cm.

[0015] Preferably, the thickness of the hard rubber is 5 cm.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, a through hole is opened at the bottom of the pile cap of the hammer pile, which is sleeved on the top of the pile, and hard rubber is provided at the connection between the inside of the pile cap and the top of the pile as a flexible support, and the top is further limited and installed by an inner support plate to maintain stability. In addition, the top is sealed by a top cover to facilitate hammering. At the same time, the use of steel plates and reinforcing pads is beneficial to increase the supporting force and strength inside, thereby ensuring the use effect. The pile cap can transfer this concentrated impact force to the pile top more evenly. Buffer materials are usually provided inside the pile cap. These buffer materials will undergo elastic deformation when impacted, so that the impact force is more evenly distributed on the pile top, avoiding the pile top from being broken, crushed or other damages due to excessive local force. The pile cap has its own structural strength and buffer mechanism. The occurrence of this deformation can be effectively reduced. The pile cap is usually equipped with a centering device to ensure that the pile cap and the pile top are accurately aligned. During the pile sinking process, alignment is very critical. If the pile cap and the pile top are not aligned, eccentric force will be generated during hammering. The centering device of the pile cap can adapt to piles of different diameters and accurately position them at the center of the pile top to ensure that the hammering force acts vertically on the pile top, thereby ensuring that the direction of pile sinking is vertical and meeting the project's requirements for the verticality of the pile foundation. When the pile hammer hits the pile top, the pile body will generate a reaction force, and the pile cap can buffer the damage of this reaction force to the pile hammer. The buffer device in the pile cap will produce elastic deformation when subjected to the reaction force of the pile body, absorbing part of the energy, thereby reducing the impact of the reaction force on the pile hammer and extending the service life of the pile hammer.

[0017] 2. In the present invention, during the process of hammering piles, the pile body is easily affected by external factors and deviates in the horizontal direction. The clamping mechanism can hold the pile body tightly to limit the lateral movement of the pile body. The clamping mechanism helps to maintain the axial force state of the pile. If there is no clamping mechanism, the hammering force may not be completely transmitted along the axial direction of the pile due to the shaking of the pile body during hammering, and a part of the force will be decomposed into lateral force. The clamping mechanism stabilizes the pile body to ensure that the hammering force is transmitted to the foundation along the axial direction of the pile as much as possible, ensuring that the pile can effectively transfer the upper structure load to the deep foundation and play its bearing role. During the pile sinking process, especially in the lifting and initial hammering stages, the pile body may fall off from the pile cap, causing a safety accident. The clamping mechanism can firmly fix the pile body to prevent it from accidentally falling off. BRIEF DESCRIPTION OF THE DRAWINGS
