[0002] The mechanical connection structure of steel bars in the pile foundation of highway bridge projects is a steel bar connection method widely used in highway bridge projects. It effectively connects the steel bars through mechanical biting or the pressure-bearing effect of the steel bar end faces to enhance the stability and bearing capacity of the entire pile foundation.

[0003] At present, the existing mechanical connection structure of steel bars mainly adopts the form of straight thread sleeves. Its basic principle is: straighten and cut the steel bars to ensure that the end faces of the steel bars are flat and undamaged, use a steel bar rolling machine to roll the ends of the steel bars to form a standard straight thread structure, connect the processed steel bar straight threads with special straight thread sleeves, and achieve a stable connection between the steel bars through mechanical bite. However, in the construction process of pile foundations of highway bridge projects, usually after the steel bars are connected, in order to optimize the stress performance of the pile foundation, the multiple groups of steel bars inside the pile foundation are arranged in a ring array. The steel bars distributed in the ring array can more effectively disperse the stress borne by the pile foundation, so that the pile foundation forms a A more compact and stable steel skeleton structure can enhance the integrity and earthquake resistance of the pile foundation and improve the safety of the bridge project. However, in actual operation, when the steel bars are mechanically connected, it is not convenient to quickly position and align the ring-shaped steel bars, which reduces the construction efficiency. In addition, in actual operation, the arrangement and alignment of multiple groups of steel bars are greatly affected by human factors, and the steel bars need to be bent and tied and fixed. The operation is cumbersome, and it is difficult to ensure the accuracy of the angles and spacings between the multiple groups of steel bars. It is impossible to ensure the accuracy and consistency of the entire steel skeleton and cannot meet the use requirements. In view of the shortcomings of the prior art, the present invention provides a highway bridge project pile foundation steel bar mechanical connection structure to solve the above problems.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The embodiment of the present application provides a mechanical connection structure for pile foundation steel bars of a highway bridge project, thereby solving the problem that during actual operation, when the steel bars are mechanically connected, it is not convenient to quickly position and align the ring-shaped steel bars, which reduces the construction efficiency. In addition, during actual operation, the arrangement and alignment of multiple groups of steel bars are greatly affected by human factors, and the steel bars need to be bent and tied and fixed specially, which is cumbersome to operate. It is difficult to ensure the accuracy of the angles and spacings between the multiple groups of steel bars, and it is impossible to ensure the accuracy and consistency of the entire steel bar skeleton, and it cannot meet the use requirements.

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] The embodiment of the present invention discloses a highway bridge engineering pile foundation steel bar mechanical connection structure. Figure 1-9 As shown, it includes a connecting base 1, a plurality of connecting rods 2 are connected to the connecting base 1, and a guide rail column 3 is provided on the connecting rod 2. The plurality of connecting rods 2 and the guide rail column 3 are distributed in a circular array on the connecting base 1, and the connecting base 1, the connecting rod 2 and the guide rail column 3 are integrally formed by a mold, which is convenient for processing and operation, and it is easy to control the installation angle of the pile foundation steel bar body 8;

[0039] The guide rail column 3 is movably connected with a sleeve 4. Since the multiple groups of guide rail columns 3 are distributed in a circular array around the connection base 1, the sleeves 4 sleeved on the guide rail columns 3 are also distributed in a circular array.

[0040] The sleeve 4 is fixedly connected with a first clamping seat 5, and a first clamping block 6 is movably clamped on the first clamping seat 5. A clamping groove 51 corresponding to the first clamping block 6 is provided on the first clamping seat 5. When the first clamping block 6 is clamped with the first clamping seat 5, the first clamping block 6 is aligned with the clamping groove 51 and clamped, and the clamping and positioning operation is convenient;

[0041] A threaded sleeve 7 is fixedly connected to the first clamping block 6. The threaded sleeve 7 is used to mechanically connect the pile foundation steel bar body 8. The pile foundation steel bar body 8 is provided with a threaded end 81. The threaded sleeve 7 is threadedly connected to the threaded end 81. The threaded end 81 on the pile foundation steel bar body 8 is formed by rolling the steel bar end with a steel bar rolling machine. The threaded end 81 is meshed with the inner cavity of the threaded sleeve 7, and a stable connection between the steel bars is achieved through mechanical bite.

[0042] Since the multiple sets of sleeves 4 are distributed in a circular array, the first clamping seat 5, the first clamping block 6, the threaded sleeve 7 and the pile foundation steel bar body 8 are also distributed in a circular array around the connection base 1, so that it is easy to control the angle between the multiple sets of threaded sleeves 7 and the pile foundation steel bar body 8;

[0043] After confirming and controlling the angles between the multiple groups of threaded sleeves 7 and the pile foundation steel bar main body 8, a positioning seat 9 is fixedly connected to the first clamping seat 5, and a positioning groove 91 is provided on the positioning seat 9. A positioning clamp ring 10 is movably clamped inside the positioning groove 91, and the positioning clamp ring 10 is clamped with the connecting base 1. When the positioning clamp ring 10 is clamped with the connecting base 1 and the positioning groove 91 at the same time, the positioning clamp ring 10 realizes the position fixing of the distance between each positioning seat 9 and the connecting base 1. Therefore, the positioning seat 9 is used to ensure that the distance between each first clamping seat 5, the first clamping block 6, the threaded sleeve 7 and the pile foundation steel bar main body 8 relative to the connecting base 1 is constant, thereby quickly realizing the determination of the distance and angle between the multiple groups of pile foundation steel bar main bodies 8;

[0044] A first locking unit 13 is provided between the first clamping seat 5 and the first clamping block 6, and a second locking unit 11 is provided between the connecting base 1 and the positioning clamping ring 10. The device facilitates the quick clamping and locking of the first clamping seat 5 and the first clamping block 6 through the design of the first locking unit 13, thereby achieving a good supporting effect on the threaded sleeve 7 and the pile foundation steel bar body 8. The design of the second locking unit 11 facilitates the quick clamping and locking between the connecting base 1 and the positioning clamping ring 10, thereby making the position clamping between the connecting base 1 and the positioning clamping ring 10 stable;

[0045] When the device is used for mechanical connection of steel bars in pile foundations of highway bridge projects, it is not only convenient to quickly connect multiple groups of steel bars, but also cooperates with the connection structure to quickly align and arrange multiple groups of steel bars, thereby improving construction efficiency. When multiple groups of steel bars are arranged in a circular array, the error caused by human factors is small, and no additional steel bar bending and bundling are required. A multi-point clamping method is adopted, and no binding and welding fixation are required. The operation is simple, and the distance and angle between multiple groups of steel bars can be accurate, ensuring the accuracy and consistency of the entire steel bar skeleton, thus meeting the use requirements.

[0046] When making mechanical connection of pile foundation steel bars of highway bridge engineering, first use threaded sleeve 7 to connect the pile foundation steel bar main body 8 that needs to be connected, then set sleeve 4 on multiple groups of connecting rods 2 and guide rail columns 3 on the side of connecting base 1, and make the first clamping seat 5 clamped with the first clamping block 6, and use the first locking unit 13 to lock the position. After multiple groups of first clamping seats 5 and first clamping blocks 6 are clamped together, clamp the positioning clamp ring 10 on the connecting base 1, and make the positioning clamp ring 10 clamped in the inside of the positioning groove 91, so as to realize the rapid positioning of multiple groups of threaded sleeves 7 and pile foundation steel bar main body 8, determine the spacing and angle between multiple groups of pile foundation steel bar main body 8, and use the second locking unit 11 to lock the position between the connecting base 1 and the positioning clamp ring 10.

[0047] The first locking unit 13 includes a support fixing seat 131 fixedly connected between the first clamping seat 5 and the positioning seat 9, a driving block 132 is movably clamped inside the support fixing seat 131, a first locking rod 133 is fixedly connected to the driving block 132, a first locking hole 61 is provided on the first clamping block 6, the first locking rod 133 is movably inserted into the first locking hole 61, a screw rod 134 is threadedly connected to the support fixing seat 131, the screw rod 134 is rotatably connected to the driving block 132, and a handle is provided on the screw rod 134, so that it is convenient and labor-saving when rotating the screw rod 134;

[0048] The device uses the design of the first locking unit 13 to facilitate the first clamping block 6 and the first clamping seat 5 to be quickly locked in position when the first clamping block 6 and the first clamping seat 5 are clamped. During operation, the first clamping block 6 and the first clamping seat 5 are first clamped. After they are fully clamped, the screw rod 134 is rotated to make the screw rod 134 rotate and push the driving block 132 to move along the inside of the supporting fixed seat 131. The driving block 132 drives the first locking rod 133 to move, so that the first locking rod 133 is inserted into the inside of the first locking hole 61, thereby realizing the clamping and locking of the first clamping block 6 and the first clamping seat 5.

[0049] The second locking unit 11 includes a second clamping seat 111 fixedly connected to the connecting base 1, a second clamping block 101 is provided on the positioning clamping ring 10, the second clamping block 101 is movably clamped inside the second clamping seat 111, a guide rail rod 112 is fixedly connected to the side of the second clamping seat 111, an adjusting platform 113 is movably clamped on the guide rail rod 112, a second locking rod 114 is fixedly connected to the adjusting platform 113, a second locking hole 102 is opened on the second clamping block 101, and the second locking rod 114 is movably clamped in the second locking hole 102.

[0050] The device facilitates the rapid clamping and limiting of the positioning clamp ring 10 and the connecting base 1 through the design of the second locking unit 11. During operation, the second clamping block 101 is first clamped with the second clamping seat 111 above the connecting base 1. After the clamping is fully engaged, the position of the adjusting platform 113 is adjusted so that the adjusting platform 113 drives the second locking rod 114 to move and the second locking rod 114 is inserted into the second locking hole 102, so that the positioning clamp ring 10 and the upper part of the connecting base 1 can be quickly clamped and locked.

[0051] The guide rail rod 112 is fixedly connected with a baffle plate 115, and a pull rod 117 is slidably connected with the baffle plate 115. The pull rod 117 is fixedly connected to the adjustment platform 113, and a spring 116 is fixedly connected between the baffle plate 115 and the adjustment platform 113. The baffle plate 115, the spring 116 and the pull rod 117 are designed on the second locking unit 11, so that when the second locking rod 114 is inserted into the second locking hole 102, the spring 116 simultaneously applies elastic force on the adjustment platform 113 and the second locking rod 114. , ensuring that the second locking rod 114 is stably inserted into the second locking hole 102, and when the position of the adjusting platform 113 needs to be adjusted, the pull rod 117 can be directly pulled, which is easy to operate. During the pulling process of the adjusting platform 113, the spring 116 will be squeezed. When the arm releases the pull rod 117, the spring 116 will automatically push the adjusting platform 113 and the second locking rod 114 to move, so that the second locking rod 114 is easy to be inserted into the second locking hole 102, while ensuring stable insertion.

[0052] A clamping unit 12 is provided on the first clamping seat 5, and the clamping unit 12 includes a hollow seat 121 fixedly connected to the sleeve 4 and the first clamping seat 5, a threaded rod 122 is threadedly connected to the hollow seat 121, and a clamping block 123 is rotatably connected to the threaded rod 122, and the clamping block 123 is slidably connected to the inside of the hollow seat 121 and clamped with the guide rail column 3. A handle is usually provided on the threaded rod 122, so that the threaded rod 122 is easy to operate when rotating.

[0053] Through the design of the clamping unit 12, when the positioning snap ring 10 is clamped with the positioning groove 91 on the positioning seat 9, the sleeve 4 and the first clamping seat 5 are conveniently clamped and locked with the guide rail column 3. During operation, the threaded rod 122 can be directly rotated, and the threaded rod 122 drives the clamping block 123 to slide along the inside of the hollow seat 121. The clamping block 123 is finally clamped with the guide rail column 3, so that the sleeve 4 and the first clamping seat 5 are restricted by the position of the positioning snap ring 10, and are also reinforced by the clamping unit 12 for the second time.

[0054] A tooth groove 31 is provided on the guide rail column 3, and the clamping block 123 is engaged with the tooth groove 31. The device is designed through the tooth groove 31 so that when the clamping block 123 is clamped with the tooth groove 31, the clamping block 123 and the tooth groove 31 are tightly clamped through the meshing form, ensuring that the sleeve 4 and the first clamping seat 5 are limited by the position of the positioning clamp ring 10, and at the same time, the secondary reinforcement effect of the clamping unit 12 is good.
