Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bent cap construction, in particular, the present application relates to a prefabricated bent cap mounting structure. BACKGROUND

[0002] The bent cap, as a part of the bridge structure, plays a role in connection and support. It is usually located above the pier column or pile foundation, used to support and transfer the load of the upper structure. In bridge construction, the elevation of the bent cap must be strictly controlled and accurate slope adjustment work must be carried out. The elevation of the bent cap determines the position and height of the bridge superstructure such as prefabricated beam, and then affects the linear and aesthetics of the whole bridge. In bridge design, the elevation of the bent cap needs to be accurately calculated to ensure the coordination and overall stability between the parts of the bridge. If the elevation of the bent cap deviates, it may cause problems in the connection between the bridge superstructure and the substructure, and even affect the carrying capacity of the bridge. Due to the influence of factors such as foundation settlement and construction error, the bent cap may be uneven or the slope may not meet the design requirements. Through slope adjustment, these deviations can be eliminated, so that the bent cap and other parts of the bridge are tightly connected to form a stable overall structure, thereby improving the carrying capacity of the bridge. The slope adjustment of the bent cap is also of great significance to driving safety. If the slope of the bent cap is too large or too small, it will cause the vehicle to vibrate or deviate during driving, increasing the risk of traffic accidents. Through accurate slope adjustment, the flatness of the bridge surface can be ensured, and the comfort and safety of driving can be improved.

[0003] At present, the combination of hoop and sand cylinder is basically used as the bent cap leveling device during the construction of bent cap, and prefabricated cushion block or rubber strip is used as the side formwork of pile top adjustment belt, but when the combination of hoop and sand cylinder is used as the bent cap leveling device, there are many auxiliary devices, the installation and positioning are complex, and the efficiency is low.

[0026] In view of the problems of many auxiliary devices and difficult installation of the combination of hoop + sand cylinder as the leveling device of bent cap in the current bent cap construction, please combine Figure 1 and Figure 2The application provides a prefabricated cap beam 1 mounting structure, which comprises a prefabricated cap beam 1 and a prestressed pipe pile 2, the prefabricated cap beam 1 is mounted on the top of the prestressed pipe pile 2, the top of the prestressed pipe pile 2 is provided with an adjusting assembly 3 for adjusting the elevation and transverse slope of the prefabricated cap beam 1, the top surface of the adjusting assembly 3 is in abutment with the bottom surface of the prefabricated cap beam 1, so that the elevation and transverse slope of the cap beam can be adjusted by adjusting the relative position of the adjusting assembly 3 and the prestressed pipe pile 2. Meanwhile, a glue piece 4 is arranged between the top surface of the adjusting assembly 3 and the bottom surface of the prefabricated cap beam 1, the glue piece 4 can realize the bonding and sealing between the adjusting assembly 3 and the prefabricated cap beam 1, the bonding strength of the two is enhanced, and the stability of the cap beam construction is ensured.

[0027] Specifically, the adjusting assembly 3 of the application comprises at least two hoop pieces 31, the adjacent ends of the two adjacent hoop pieces 31 are connected and fixed through a threaded fastener 33. The hoop design is flexible, can be adapted to the fixation of prestressed pipe piles 2 with different diameters, is simple and fast to install, and the hoop pieces 31 can be tightly locked on the prestressed pipe pile 2 after being locked through the threaded fastener 33, the load is transmitted through the friction force, the safety and stability of the whole structure are improved, and the deformation or movement of the prestressed pipe pile 2 caused by external load can be effectively prevented.

[0028] Further, the end of the hoop piece 31 extends outward to form a connecting piece 32, the connecting piece 32 is provided with a connecting hole through which the threaded fastener 33 passes, so that the adjacent ends of the two adjacent hoop pieces 31 are connected and fixed, the threaded fastener 33 of the embodiment is locked by a screw rod cooperating with a nut, and is convenient to assemble and disassemble,

[0029] Still further, the connecting pieces 32 between the ends of the two hoop pieces 31 are provided with rubber pads 34, the rubber pads 34 can increase the sealing effect, so as to prevent the leakage of cement soil during subsequent cement soil pouring at the gap between the two connecting pieces 32 of the two hoop pieces 31, and since the rubber pad 34 has a certain elasticity and friction force, it can increase the friction force between the connecting pieces 32 of the hoop pieces 31, so as to prevent the loosening of the hoop pieces 31 due to external force in the long-term use process, thereby improving the stability of the adjusting assembly 3 of the application mounted on the top of the prestressed pipe pile 2.

[0030] In addition, the inner side of the hoop piece 31 is provided with an elastic layer 35 abutting against the outer wall of the prestressed pipe pile 2. The connection between the hoop piece 31 and the prestressed pipe pile 2 needs sufficient friction to ensure stability. The elastic layer 35 can fill the small gap between the hoop and the prestressed pipe pile 2, increase the contact area, and thus tightly fix the hoop on the prestressed pipe pile 2 through friction. Since the outer wall of the prestressed pipe pile 2 is usually fragile and vulnerable to external force, the elastic layer 35 acts as a buffer to disperse and absorb the pressure of the hoop piece 31 on the outer wall of the prestressed pipe pile 2, thereby avoiding direct damage. At the same time, the flexibility of the elastic layer 35 can also adapt to the possible slight deformation of the outer wall of the prestressed pipe pile 2, and keep the tight fit between the hoop and the prestressed pipe pile 2.

[0031] Moreover, the installation angle of the hoop piece 31 relative to the prestressed pipe pile 2 can also be adjusted by adjusting the degree of extrusion of the elastic layer 35. Since the top surface of the hoop piece 31 directly abuts against the bottom surface of the bent cap, the installation angle of the hoop piece 31 is adjusted to achieve the purpose of adjusting the transverse slope of the bent cap. Meanwhile, the height of the hoop piece 31 above the top surface of the prestressed pipe pile 2 can also be adjusted to achieve the purpose of adjusting the elevation of the bent cap. Therefore, in this embodiment, the width of the hoop piece 31 is greater than 20 cm, which can adjust the elevation of the bent cap by at least 12 cm.

[0032] In this embodiment, the adhesive is double-sided tape. The use of double-sided tape is relatively simple and does not require complex installation processes or special skills. It only needs to be pasted on the contact surface of the hoop and the bent cap. Compared with welding or bolt connection, the bonding speed of double-sided tape is faster, which can shorten the construction time to a certain extent. The use of double-sided tape does not require additional welding equipment, bolts or nuts, thereby reducing the construction cost and equipment investment.

[0033] After the adjustment assembly 3 and the bent cap are fixed by double-sided tape, the prestressed pipe pile 2 can be connected to the prefabricated bent cap 1 by pouring concrete. The prefabricated bent cap 1 is provided with a hole 11 for interchanging concrete. The prefabricated bent cap 1 is provided with a steel cage 12 in the hole 11. The bottom of the steel cage 12 extends downward into the prestressed pipe pile 2. The steel cage 12 acts as a connecting bridge between the prefabricated bent cap 1 and the prestressed pipe pile 2, which can significantly improve the connection strength between the two. By extending the bottom of the steel cage 12 into the prestressed pipe pile 2, the tight connection between the prefabricated bent cap 1 and the prestressed pipe pile 2 can be ensured, thereby forming a more stable overall structure.

[0034] In summary, the prefabricated bent cap 1 installation structure of the present application uses the hoop piece 31 as the adjustment assembly 3 to adjust the elevation and transverse slope of the prefabricated bent cap 1. The use of double-sided tape can realize the quick bonding and fixing of the prefabricated bent cap 1 and the adjustment assembly 3, and has good sealing performance, which is conducive to the sealing performance of subsequent concrete pouring.

[0035] The above merely describes some embodiments of the present application, and it should be pointed out that, for those skilled in the art, other similar implementation manners based on the technical concept of the present application can be adopted without departing from the technical concept of the present application, and these also belong to the protection scope of the embodiments of the present application.
