Description

Technical Field

[0001] This utility model relates to the field of cap beam support technology, specifically a structure suitable for independent cap beam support. Background Technology

[0002] As modern bridge engineering develops towards longer spans, heavier loads, and taller piers, the cap beam, as a key load-bearing component connecting the pier and the superstructure, has a crucial stability and safety in its construction support system. The cap beam requires regular maintenance, but there is not enough space to place tools when maintaining the bottom of the cap beam, which affects the maintenance operation.

[0003] For example, the authorized patent document with application number CN202021735268.7 discloses a bridge cap beam support device, including several horizontal and parallel pins, all with flush top surfaces. Each pin's protruding end has a steel sand box on its top surface, and a horizontal main beam is positioned above the steel sand box. The bottom surface of the main beam is in contact with the top surface of the steel sand box, and a slope-finding frame with an inclined top surface is attached to the top surface of the distribution beam. This utility model can improve construction efficiency and economic benefits: it eliminates the need for foundation treatment under the cap beam, reduces the workload, saves manpower, and improves economic efficiency; it also shortens construction time, increasing efficiency. Quality is improved: both the main beam and the distribution beam use structural steel, resulting in minimal deformation during concrete pouring and ensuring the quality of the cap beam construction.

[0004] The aforementioned patent has the problem that there is not a good space to place tools when maintaining the bottom of the cap beam. Therefore, we need to provide a structure suitable for independent cap beam support. Utility Model Content

After the inspection is completed, the tools can be removed, the placement racks can be pushed up and close to the steel frame and fixed, avoiding the need for operators to frequently climb up and down to retrieve and place tools. There is no need to set up an additional temporary inspection platform, reducing construction costs and labor time, and solving the problems mentioned in the background art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a structure suitable for independent cap beam support, comprising:

[0023] The steel frame 1, the embedded plate 2, the support leg 3, and the placement rack 4 are fixedly installed on the bridge surface. The support leg 3 is fixedly installed on both sides of its bottom. The bottom of the support leg 3 is connected to the embedded plate 2, and the embedded plate 2 is embedded in the bridge surface. The two placement racks 4 are located at the bottom of the steel frame 1 and are used to temporarily place tools during maintenance.

[0024] Specifically, two storage racks 4 are provided at the bottom of the steel frame 1. When the bottom structure of the steel frame 1 is being inspected, the storage racks 4 can be pulled out and the tools used can be temporarily placed inside the storage racks 4 for convenient inspection work. After the inspection is completed, the tools can be taken out, the storage racks 4 can be pushed up and close to the steel frame 1 and fixed, avoiding the need for operators to frequently climb up and down to retrieve and place tools. There is no need to set up an additional temporary inspection platform, reducing construction costs and labor time.

[0025] The display rack 4 includes a mesh frame 41, a base 42, a crossbar assembly 43, and a limiting member 44. The mesh frame 41 is provided with two crossbar assemblies 43. The upper and lower ends of the crossbar assemblies 43 are hinged to the base 42. The upper base 42 is fixedly installed at the bottom of the steel frame 1, and the lower base is fixedly installed on the inner wall of the mesh frame 41. The limiting member 44 is used to bring the mesh frame 41 close to the bottom of the steel frame 1 and fix it.

[0026] Furthermore, when using the space frame 41, it can be separated from the steel frame 1 and pulled down. The two crossbar groups 43 deform, making it convenient to temporarily place tools inside the space frame 41. When the space frame 41 is pulled down, it is hinged to the steel frame 1 through the crossbar groups 43, and its weight is borne by the steel frame 1 and the support legs 3, without adding extra load to the main body of the bridge. When not in use, the space frame 41 can be moved up and fixed by the limiting member 44. The space frame 41 has gaps inside for air circulation. The gap structure reduces the self-weight of the space frame 41 and reduces the area affected by wind, thus improving wind resistance stability.

[0027] The limiting component 44 includes a plate 441, a limiting rod 442, and a fixing frame 443. The two plates 441 are fixed on both sides of the grid frame 41 respectively. The limiting rod 442 is movably sleeved inside the plate 441. The two fixing frames 443 are fixed at the bottom of the grid frame 41 and are located at the top of the two limiting rods 442 respectively. The fixing frame 443 has a hole that is threadedly connected to the limiting rod 442.

[0028] It is worth noting that when the space frame 41 is retracted, the limiting rod 442 inside the plate 441 is threaded into the inner hole of the fixing frame 443 to fix the space frame 41. The plate 441 is welded to the surface of the space frame 41, the limiting rod 442 is movably sleeved inside the plate 441, and the top of the fixing frame 443 is welded to the bottom of the steel frame 1. The thread on the surface of the limiting rod 442 has a self-locking function. The threaded connection between the limiting rod 442 and the hole of the fixing frame 443 utilizes the self-locking principle that the helix angle is less than the friction angle. Even under dynamic loads such as vibration, wind force, or tool collision, the friction of the threaded contact surface can prevent the limiting rod 442 from loosening on its own. Maintenance personnel can easily turn the knob at the bottom of the limiting rod 442 by hand to screw it into the hole of the fixing frame 443. The limiting rod 442 is galvanized to enhance its corrosion resistance.

[0029] The surface of the limiting rod 442 is integrally formed with an anti-detachment ring 5 to prevent the limiting rod 442 from falling off.

[0030] Specifically, the anti-detachment ring 5 is a ring structure protruding from the surface of the limiting rod 442. When the limiting rod 442 moves within the plate 441, the anti-detachment ring 5 is engaged with the outer end face of the plate 441 to form a mechanical stop, preventing the limiting rod 442 from falling from a height and injuring personnel or equipment below.

[0031] The support leg 3 includes a diagonal rod 31 and a shear beam 32. The top of the diagonal rod 31 is fixedly installed at the bottom of the steel frame 1, and the lower end is fixedly connected to the embedded plate 2. A shear beam 32 is provided between the two diagonal rods 31.

[0032] It should be noted that the diagonal brace 31 connects the steel frame 1 and the embedded plate 2 at an inclination angle of 45°, converting the vertical load borne by the steel frame 1 into the axial pressure of the diagonal brace 31. Compared with straight rod support, axial force can improve the utilization rate of material strength. The diagonal brace 31 has a significant resistance to horizontal loads: the inclination angle forms a horizontal component force, which can offset part of the lateral force and reduce the horizontal displacement of the steel frame 1. The diagonal brace 31, shear beam 32 and the bottom of the steel frame 1 form a triangular structure. By utilizing the geometric invariance of the triangle, the support leg 3 can maintain its shape stability when bearing loads in any direction.

[0033] The bottom of the steel frame 1 is equipped with four mechanical jacks 6, and each of the four mechanical jacks 6 is fixedly installed with a bracket 7. The surface of the bracket 7 is fixedly connected to the embedded parts inside the bridge.

[0034] Furthermore, the four mechanical jacks 6 can be independently adjusted in height to achieve precise calibration of the level of the steel frame 1. The self-locking function of the jacks can maintain the support force after adjustment, avoiding the settlement of the steel frame 1 due to load fluctuations. The bracket 7 distributes the concentrated load at the bottom of the jacks to the bridge embedded parts. The welding of the bracket 7 and the embedded parts forms a rigid node to ensure reliable load transfer and avoid the jacks directly acting on the bridge surface, which could cause concrete cracking.

[0035] An operating platform 8 is fixedly installed on the top of the steel frame 1, and the steel frame 1 is an I-beam;

[0036] Among them, steel frame 1 uses I-beams, which have an I-shaped cross section, wide flanges, thin web, and a higher bending section modulus than rectangular steel of the same weight.

[0037] In this application, the steel frame 1 is located on the surface of the bridge. The bridge deck at the top of the bridge is relatively wide, which can protect the steel frame 1 from rainwater erosion. At the same time, it will not be operated in windy weather, thus avoiding the violent swaying of the grid frame 41 in use due to excessive wind force.

[0038] This device has two placement racks 4 at the bottom of the steel frame 1. When the bottom structure of the steel frame 1 is being inspected, the space frame 41 can be separated from the steel frame 1 and pulled down. The two crossbar groups 43 deform, making it convenient to temporarily place tools inside the space frame 41. When the space frame 41 is pulled down, it is hinged to the steel frame 1 through the crossbar groups 43. Its weight is borne by the steel frame 1 and the support legs 3, without adding extra load to the main bridge load. When not in use, the space frame 41 can be moved up and fixed by the limiting piece 44. Tools can be temporarily placed inside the placement rack 4 for convenient inspection work. After the inspection is completed, the tools can be removed, the placement rack 4 can be pushed up and close to the steel frame 1 and fixed. This avoids operators having to climb up and down to retrieve and place tools, eliminates the need for an additional temporary inspection platform, reduces construction costs and labor time.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
