[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Among the currently discovered feasible technologies, the fixing support is as follows:

[0022] I. Concept

[0023] A fixed support is a device used to stably support an object and restrict its movement in one or more directions. It has wide applications in many fields such as construction, machinery, and electronics.

[0024] (I) Construction Field

[0025] In building structures, fixed supports are crucial for ensuring the stability and safety of the building. For example, in the construction of reinforced concrete frame structures, fixed supports at the column bases prevent the columns from shifting during concrete pouring. These supports are typically connected to the foundation via anchor bolts, transferring the forces on the columns to the foundation.

[0026] For steel structure buildings, fixed supports (such as corner braces and horizontal braces) between steel beams and columns can enhance the overall stability of the structure. Corner braces can prevent lateral torsion of the beams, while horizontal braces can reduce the swaying of the structure in the horizontal direction.

[0027] (II) Mechanical Field

[0028] In machine tools, fixed supports are used to hold workpieces in place and ensure machining accuracy. For example, the chuck on a lathe is a fixed support; it clamps the workpiece with jaws, keeping it stable during high-speed rotation. In milling, the fixtures on the worktable are also fixed supports, firmly fixing the workpiece to the worktable and preventing machining errors caused by vibration during milling.

[0029] The installation of large mechanical equipment also relies on fixed support components. For example, the base of a large generator is connected to the foundation through multiple fixed support components. These support components can absorb the vibrations generated during equipment operation and ensure the positioning accuracy of the equipment.

[0030] (III) Electronics Field

[0031] During circuit board installation, mounting supports (such as circuit board brackets) can secure the circuit boards in a suitable position within the chassis, preventing damage from external impacts or vibrations. Furthermore, these supports ensure proper spacing between circuit boards, which is beneficial for heat dissipation and wiring.

[0032] II. Main Types

[0033] Rigid fixed support

[0034] The shape and size of such support is fixed and will not deform substantially once installed. For example, a pre-embedded part in a concrete foundation in a building, which is a steel member embedded in the foundation in advance, is fixed to the subsequent structural column or equipment by welding or bolting, etc. The advantage of rigid support is that it has very high stability and can withstand large static and dynamic loads. However, the disadvantage is that it lacks flexibility and requires high installation accuracy. Once the installation position is deviated, it is difficult to adjust.

[0035] Elastic fixing support

[0036] It has a certain elastic deformation capacity. In electronic equipment, such as some shock-absorbing support feet made of rubber materials, it can elastically deform when the equipment is subjected to slight vibration, thereby absorbing vibration energy and playing a shock-absorbing role. In the mechanical field, spring support is also a common elastic fixing support. It can automatically adjust the support force according to the size of the load during equipment operation, so that the equipment maintains a balanced state. However, the carrying capacity of the elastic support is relatively weak compared with the rigid support. When subjected to a large load, it may appear excessive deformation.

[0037] III. Design points

[0038] Load calculation

[0039] First, determine the size of the load that the fixing support needs to bear. In building structures, factors such as the weight of the building, wind load, seismic load, etc. need to be considered. For example, when designing the fixing support of the outer wall panel of a high-rise building, the pressure generated by the wind load on the wall panel needs to be calculated, and the carrying capacity of the support is determined according to the local wind pressure standard value and the area of the wall panel. In the mechanical field, the carrying capacity required by the support is calculated according to the weight of the equipment, the dynamic load generated during work (such as the centrifugal force of rotating parts), etc.

[0040] Material selection

[0041] Select appropriate materials according to the load, working environment, etc. of the support. For building supports that bear large static loads, high-strength steel or concrete is generally selected. In corrosive environments, such as equipment supports in chemical plants, corrosion-resistant stainless steel or glass steel materials may need to be selected. In electronic equipment, in order to avoid electromagnetic interference, materials with good electromagnetic shielding performance may be selected to make the support.

[0042] Connection design

[0043] The connection between the fixed support and the supported object and the foundation is crucial. In the field of construction, common connection methods include welding, bolting, and riveting. Welded connections have high strength, but once the welding is complete, they are not easy to disassemble and adjust; bolted connections are easy to install and disassemble, but attention must be paid to the pre-tightening force of the bolts to prevent loosening; riveted connections are used in situations where the connection strength is not particularly high, and their advantage is that the process is simple. In the mechanical and electronic fields, in addition to the above connection methods, sleeve connections, glue pasting, and other methods are also used, and the specific choice depends on the material and working requirements of the supported object.

[0044] The fixed support for precast component installation is as follows:

[0045] I. Definition

[0046] The fixed support for precast component installation is a component used for temporary or permanent fixation and support of precast components during the installation process. Its purpose is to ensure the accurate positioning and good stability of precast components during the installation stage, ensuring construction safety and structural quality.

[0047] II. Types

[0048] Adjustable support

[0049] This support is usually composed of a screw rod, an adjusting nut, and a base. For example, in the installation of precast wall panels, by rotating the adjusting nut, the extension length of the screw rod can be accurately adjusted, so that the wall panel meets the design requirements of verticality and levelness. Its advantage is that the height is adjustable, and it can adapt to the installation accuracy requirements of different precast components, and is widely used in construction sites.

[0050] Fixed length support

[0051] It has a fixed length specification, which is usually pre-made according to the size and installation requirements of specific precast components. For example, the diagonal support used in the installation of precast stairs is designed according to the slope and span of the stairs. Its structure is relatively simple, and the cost is relatively low, and it is used in cases where the installation accuracy requirements are relatively low or the component size is relatively standard.

[0052] Combined support

[0053] It is composed of multiple different components and can be flexibly spliced according to actual installation conditions. For example, the installation support of some large precast beams may combine steel pipes, steel sections, etc. through connecting pieces to form a stable support structure. This support has strong carrying capacity and can adapt to complex precast component shapes and installation conditions.

[0054] III. Materials

[0055] Steel

[0056] Steel is the most common material. For example, Q235 and Q345 carbon structural steel, which has high strength and good toughness, can bear large loads. When making support components, steel can be processed into various shapes, such as steel pipes for making vertical support columns, and steel sections (such as I-beams and channel steels) for making beam supports or frame structures of combined supports.

[0057] Aluminum alloy

[0058] Aluminum alloy materials have the advantages of light weight and corrosion resistance. In some situations where the weight of the support components is required, such as high-rise construction of prefabricated buildings, aluminum alloy support components can be easily lifted and installed. However, the strength of aluminum alloy is relatively low compared to steel, so its carrying capacity needs to be considered in design and use.

[0059] Four, installation points

[0060] Accurate positioning

[0061] Before installing the prefabricated component fixed support, the support point needs to be accurately positioned according to the construction drawings. For example, when installing prefabricated columns, the position of the support components should match the position of the anchor bolts at the column foot to ensure that the columns can be accurately placed at the designed position. Generally, total station, level, and other measuring instruments are used for positioning and setting out.

[0062] Firm connection

[0063] The connection between the support components and the prefabricated components, as well as the connection between the support components and the foundation, must be firm. If using bolt connection, the bolt specification should meet the design requirements, and the tightening torque should reach the specified standard. For welded connections, the welding quality must be guaranteed, and the height and length of the welds must meet the requirements of the welding process evaluation.

[0064] Pre-tightening force control

[0065] For adjustable support components, appropriate pre-tightening force needs to be applied after adjustment. Insufficient pre-tightening force may cause displacement of the prefabricated components during construction, while excessive pre-tightening force may damage the prefabricated components or the support components themselves. The size of the pre-tightening force is usually determined based on factors such as the weight and size of the prefabricated components, and the carrying capacity of the support components.

[0066] Five, quality inspection

[0067] Visual inspection

[0068] Check the surface of the support components for cracks, deformation, rust, and other defects. For steel-made support components, if the surface has severe rust, it will reduce its carrying capacity and needs to be rusted or replaced. If aluminum alloy support components are deformed, it may affect their installation accuracy and stability.

[0069] Dimensional inspection

[0070] Check whether the dimensions of the support meet the design requirements. Mainly includes length, diameter, wall thickness and other key size parameters. If the size deviation is too large, it may cause the installation position of the prefabricated component to be inaccurate or the support to be unable to be normally installed.

[0071] Load capacity test

[0072] For important prefabricated component installation supports, load capacity test is required. The load equivalent to a certain multiple (such as 1.2-1.5 times) of the weight of the prefabricated component can be applied to the support in a simulated loading manner to observe whether there are obvious deformation or damage signs of the support to verify whether its load capacity meets the requirements.
