Description

Technical Field

[0001] This utility model belongs to the field of steel structure construction technology, specifically a steel structure support that is easy to maintain. Background Technology

[0002] Steel structure bearings are widely used in engineering structures such as bridges, buildings, and large stadiums. Their main function is to support the superstructure, transfer loads to the foundation, and allow a certain degree of displacement or rotation to adapt to external forces such as temperature changes and earthquakes. Common steel structure bearings include fixed bearings, sliding bearings, and spherical bearings. These bearings must withstand dynamic loads and environmental factors during long-term use; therefore, maintenance and adjustment are crucial to ensuring structural safety and durability.

[0003] Currently, existing steel structure supports are designed primarily for initial installation stability, but lack convenient maintenance and adjustment mechanisms. The jacking force of steel structure supports needs to be adjusted according to structural settlement or load changes, but existing designs often rely on temporary lifting with external jacks and fixing with welded steel plates, lacking an integrated adjustment system, resulting in cumbersome and low-precision operation. Furthermore, when support components are damaged or need replacement, it is usually necessary to completely remove the upper load and construct temporary additional supports for centralized handling, a complex process fraught with safety risks.

[0004] To address the aforementioned issues, there is an urgent need in this field for a steel structure support that integrates adjustable and independent maintenance functions, enabling rapid adjustment, stress relief, and component replacement of the support without discontinuing the overall structure, thereby improving maintenance efficiency, reducing costs, and enhancing structural adaptability. Utility Model Content

[0005] The purpose of this invention is to provide an easy-to-maintain steel structure support to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-maintain steel structure support, comprising a base plate, the base plate having multiple first fixing bolts, two telescopic rods, and two first jacks, with a U-shaped plate above the first jacks, and an mounting plate installed above the U-shaped plate. The mounting plate consists of a lower mounting plate, an upper mounting plate, and a buffer plate. The upper mounting plate has two slide rails, on which permanent supports are installed. The permanent supports have wedges inside, and the rear ends of the wedges have second fixing bolts and springs. The mounting plate also has four grooves, with maintenance supports at the rear ends of the grooves, and temporary supports can be installed on the grooves.

[0007] As a preferred embodiment of this utility model, the two telescopic rods are symmetrically arranged on the top surface of the foundation plate.

[0008] In a preferred embodiment of this utility model, the two first jacks are symmetrically arranged on the top surface of the foundation plate.

[0009] As a preferred embodiment of this utility model, the bottom surface of the U-shaped plate is provided with two circular grooves for cooperating with the first jack.

[0010] As a preferred embodiment of this utility model, the bottom surface of the lower mounting plate is provided with two circular grooves for cooperating with the telescopic rod.

[0011] In a preferred embodiment of this utility model, the telescopic rod consists of an inner telescopic rod and an outer telescopic rod, and the inner telescopic rod and the outer telescopic rod are connected by a self-locking thread.

[0012] As a preferred embodiment of this utility model, the buffer plate is made of polytetrafluoroethylene.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The support adopts a combination structure of a primary jack and a telescopic rod. When the jacking force needs to be adjusted, simply activate the primary jack to lift the U-shaped plate, temporarily transferring the upper load to the jack. At this time, the self-locking thread of the telescopic rod becomes ineffective, allowing the inner telescopic rod to be rotated for length adjustment. After adjustment, unload the jack, and the load is transferred to the telescopic rod through the mounting plate, achieving thread self-locking. This avoids the cumbersome process of disassembly or use of external equipment required for traditional support adjustments, improving adjustment efficiency and reducing labor and time costs.

[0015] The support features a groove, maintenance support, and temporary support on the upper mounting plate. When the permanent support needs adjustment or replacement, a temporary support can be installed on the groove, and a second jack can be used to lift the spherical node of the upper steel structure through the temporary support, thus unloading the permanent support. This design allows maintenance work to be carried out without affecting the overall structural stability, avoiding the high-risk operation of completely removing or unloading the upper load as in traditional methods, reducing safety risks and maintenance costs.

Detailed Implementation

[0025] 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.

[0026] Please see Figure 1-8One specific embodiment of this utility model is as follows: an easy-to-maintain steel structure support includes a base plate 1, on which a plurality of first fixing bolts 2 are provided, and the base plate 1 is fixed to the foundation surface by the first fixing bolts 2. Two telescopic rods 3 and two first jacks 4 are symmetrically arranged on the top surface of the base plate 1. A U-shaped plate 5 is provided above the two first jacks 4, and an mounting plate 6 is installed above the U-shaped plate 5. The top surface of the first jacks 4 contacts the bottom of the legs on both sides of the U-shaped plate 5, while the top surface of the telescopic rods 3 contacts the bottom of the mounting plate 6. Circular grooves are provided at corresponding positions on the bottom of the U-shaped plate 5 and the mounting plate 6 to prevent slippage. The telescopic rod 3 consists of an inner telescopic rod 301 and an outer telescopic rod 302, which are connected by a self-locking thread and equipped with a safety nut. Using the first jack 4 to lift the U-shaped plate 5 and the upper structure, after reaching the designed jacking force, the inner telescopic rod 301 is rotated to extend the telescopic rod 3. When the top surface of the telescopic rod 3 presses against the mounting plate 6, the first jack 4 is unloaded. The pressure of the upper steel structure is transmitted to the telescopic rod 3 through the mounting plate 6, achieving threaded self-locking between the inner telescopic rod 301 and the outer telescopic rod 302. When it is necessary to adjust the support jacking force, the first jack 4 is used again to lift the U-shaped plate 5, allowing the pressure of the upper steel structure to be transmitted to the first jack 4 through the U-shaped plate 5. The threaded self-locking between the inner telescopic rod 301 and the outer telescopic rod 302 is disengaged, thus allowing adjustment of the telescopic rod 3.

[0027] The mounting plate 6 consists of a lower mounting plate 601, an upper mounting plate 603, and a buffer plate 602, with the buffer plate 602 made of polytetrafluoroethylene (PTFE). The upper mounting plate 603 has two slide rails 604 arranged in a cross shape, with two permanent supports 7 mounted on each slide rail 604. Each permanent support 7 has a triangular cross-section with an arc-shaped hypotenuse. Four permanent supports 7 form a semi-circular support for fixing the spherical nodes of the upper steel structure. Inside each permanent support 7 is a wedge 702. A second fixing bolt 701 and a spring 703 are located at the rear of each wedge 702. By screwing in the second fixing bolt 701, the wedge 702 can be pushed inward, causing its inclined surface to fit tightly against the inclined surface inside the permanent support 7, achieving wedge-shaped self-locking. Part of the pressure from the upper steel structure is transmitted to the slide rails 604 through the wedge 702, preventing the permanent supports 7 from sliding on the slide rails 604. When the wedge 702 is locked, the spring 703 is in the extended state, which releases the pressure on the upper steel structure and unscrews the second fixing bolt 701. The self-locking of the wedge 702 and the permanent support 7 fails, and the spring 703 pulls the wedge 702 out, allowing the permanent support 7 to slide freely on the slide rail 604.

[0028] The upper mounting plate 603 is also provided with four sliding grooves 605, and a maintenance support 606 is provided at the rear end of each sliding groove 605. Each sliding groove 605 can be equipped with a temporary support 8. When it is necessary to adjust or replace the permanent support 7, a temporary support 8 is installed on the sliding groove 605, and a second jack 607 is installed between the temporary support 8 and the maintenance support 606. The second jack 607 is adjusted to lift the spherical node of the upper steel structure by the temporary support 8, thereby unloading the permanent support 7 and enabling the permanent support 7 to slide and be disassembled.

[0029] 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.
