Description

Technical Field

[0001] The utility model relates to the technical field of bridge support cushion stone construction, in particular to an assembled steel sleeve. Background Art

[0002] Bridge bearings and pad stones play an important role in bridge engineering. Bridge bearings are key components of bridge structures. They are located between bridge piers and bridge beams and are used to transfer and disperse the load of the bridge to the piers to ensure the stability and safety of the bridge structure. Pad stones are a cushion layer under bridge bearings, which are used to evenly distribute and transfer loads to piers or abutments, reduce the local pressure of loads on bearings and piers, and ensure the normal operation and use of bridge structures.

[0003] As time goes by, the bridge piers may sink or for other reasons, resulting in the bridge clearance not meeting the regulatory requirements. The commonly used methods in engineering are to dismantle and rebuild the entire bridge or to raise the supporting pedestal stones. However, the overall dismantling and reconstruction of the bridge will not only consume a lot of manpower and material resources, but also have certain safety hazards. Raising the supporting pedestal stones will often cause construction inconveniences and increase the difficulty of construction due to the unchanged construction platform and small construction space.

A plurality of angle steels 1 are spliced ​​in sequence to form a stable sleeve body structure, and the angle steel 1 is prefabricated in advance according to the actual situation on site; at least one steel hoop 2 is transversely sleeved on the outer periphery of the sleeve body, and the number and size of the steel hoop 2 are prepared according to the actual specifications of the angle steel 1. After the angle steel 1 is spliced ​​and fixed, the sleeve body is tied and fixed with the steel hoop 2; a plurality of anchor bolts 3 pass through the angle steel 1 to fix the angle steel 1 on the top of the bridge pier, and the number and size of the anchor bolts 3 are determined according to the actual specifications of the angle steel 1.

[0025] The utility model provides an assembled steel sleeve, which is a solution to the problem that the bridge clearance does not meet the regulatory requirements due to pier settlement or other reasons. A prefabricated assembled steel sleeve is used for installation, heightening and pouring on the original pad stone, thereby achieving the effect of lifting the beam, so that the bridge meets the clearance requirements again, thereby protecting the safety of the bridge structure. By adopting the prefabricated assembled steel sleeve, the cost of construction work is reduced and the efficiency of construction work is improved.

[0026] Specifically, see Figure 2 As shown, in one embodiment, the angle steel 1 includes a vertical surface 11 and a horizontal surface 12 which are perpendicular to each other and integrally connected, and the vertical surfaces 11 of adjacent angle steels 1 are fixedly connected to each other to form a sleeve body. Further, a plurality of protrusions 111 are provided on one end surface of the vertical surface 11, and a plurality of recesses 112 are provided on the other end surface of the vertical surface 11. The protrusions 111 and the recesses 112 are riveted to each other, and two adjacent vertical surfaces 11 are fixedly connected by riveting the protrusions 111 and the recesses 112. The shape of the sleeve body can be, but is not limited to, Figure 1The rectangle shown is determined according to the actual padding conditions. During the installation process, the transverse surface 12 fits the top of the pier, and multiple anchor bolts 3 are evenly arranged on the transverse surface 12, and the transverse surface 12 is fixedly connected to the top of the pier through the anchor bolts 3.

[0027] See also Figure 2 As shown, in one embodiment, the vertical edge of the vertical surface 11 is provided with a limiting notch 113 adapted to the steel hoop 2. The steel hoop 2 includes a hoop band 21 and a bayonet 22. The bayonet 22 is used to lock the hoop band 21 to the outer periphery of the sleeve body. The setting of the limiting notch 113 prevents the steel hoop 2 from slipping during the binding and fixing process. In addition, a handle 4 is also provided on the outer periphery of the angle steel 1. The handle 4 can be installed at the center of the vertical surface 11. The handle 4 facilitates construction workers to assemble the angle steel 1 and other construction operations.

[0028] When using the assembled steel sleeve provided by the utility model, a jack is first used to lift the entire bridge body and remove the original support. On the original pad stone of the pier, the prefabricated mortise and tenon type unequal-sided angle steel 1 is spliced ​​around the pad stone as a whole to form a fixed sleeve body structure. Then, the steel hoop 2 is used to bind and fix the sleeve body as a whole. After the steel hoop 2 is bound and fixed, the anchor bolt 3 is used to pass through the angle steel 1 and connect and fix it to the top of the pier, so that the entire assembled steel sleeve is anchored on the pier as a whole. After the assembled steel sleeve is installed and fixed, grouting can be poured into the interior of the sleeve body without removing the pad stone, and then a new support is installed, thereby achieving the effect of lifting the beam, so that the bridge meets the clearance requirements again, and then the safety of the bridge structure is protected.
