[0030] The embedded bars 2 are evenly installed inside the support base plate 1, and the support base plate 1 is fixed in the wall through the embedded bars 2. During use, the support base plate 1 is pre-embedded and installed inside the wall through the embedded bars 2, which improves the stability of the support base plate 1 during installation and avoids the reduction of stability of the support base plate 1 during the support process, thereby improving the overall strength of the device, and also facilitating the installation and disassembly of the device, and being able to adapt to different environments, thereby improving the flexibility of the device.

Example 3

[0032] Please refer to Figure 1 , Figure 2 and Figure 4 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that this embodiment provides an assembled prestressed steel pipe support device, specifically.

[0033] The sizes of the hoop body 10 and the supporting steel pipe 8 match each other, and the reinforcing steel plates 11 are evenly distributed on the outside of the hoop body 10. After the device is installed during use, if the installation distance of the devices is uneven or the distance between the devices is too long, the hoop body 10 is installed on the outside of the supporting steel pipe 8, and then different supporting steel pipes 8 are supported and connected through hoop support ribs 15 to improve the structural stability and bearing capacity of the installation device.

[0034] The hoop support rib 15 forms a rotating structure with the side mounting plate 12 through the cooperation between the connecting shaft 14 and the connecting plate 13.

[0035] Please refer to Figure 5 and Figure 6 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that this embodiment provides an assembled prestressed steel pipe support device, specifically.

[0036] The axial force gauge 17 is symmetrically installed on the outside of the upper shell 16, and the center line between the center point of the upper shell 16 and the supporting steel pipe 8 coincides with each other. The axial force gauge 17 and the upper shell 16 are smoothly installed, and an axial force gauge 17 is placed on each side of the interior of the upper shell 16. The center points of the two axial force gauges 17 and the supporting steel pipe 8 are in a straight line, and each contact surface is flat, ensuring that the stress state of the supporting steel pipe 8 is normally transmitted to the supporting structure through the axial force gauge 17, so as to realize the axial force test of the steel support. When the tested support body is subjected to stress, the axial force gauge 17 will be compressed and deformed, and the upper shell 16 will deform synchronously, which is transmitted to the steel string and converted into a change in the stress of the steel string, thereby changing the vibration frequency of the steel string. The electromagnetic coil excites the steel string and measures its vibration frequency. The frequency signal is transmitted to the frequency meter via the cable, and the axial force of the tested pile body can be measured.

After unloading the prestress, the sand mouth 20 is opened, and a gap appears around the ball head 23. There is no need to re-jack the supporting steel pipe 8, and the steel support removal work can be easily completed. The device is simple and easy to operate, avoiding the risk of cutting the parent material due to difficulty in re-jacking. It is green, environmentally friendly, efficient and energy-saving.

The triangular support plate 24 is installed in an array at the bottom of the fixed mounting plate 25. The triangular support plate 24 has a triangular structure, so that the triangular support plate 24 and the fixed mounting plate 25 have stronger support for the supporting steel pipe 8, and the triangular support plate 24 is cross-installed on the right side of the fixed mounting plate 25, which makes the triangular support plate 24 stronger.

[0040] The embedded steel bars 29 are installed in an array inside the embedded base plate 26. The embedded steel bars 29 are evenly distributed inside the embedded base plate 26, which can increase the structural strength and provide a strong connection force, thereby increasing the overall strength and stability of the structure. In the installation process, the embedded steel bars 29 and the steel bar sleeves 28 are arranged on the wooden board through the pre-set holes to avoid direct lifting of the steel plate and reduce the overall lifting weight. After the strength reaches the design requirements, the steel plate is lifted and the nuts 27 are tightened to complete the pre-embedded and post-embedded construction of the steel plate, thereby solving the problem that the embedded parts cannot be reused, resulting in waste of materials.

[0041] Working principle: First, during use, the support steel pipe 8 is fixed together with the installation steering plate 5 through the high-strength bolts 7 and the fixing plate 6 at the top. The fixing plate 6 is made of high-strength material to improve the stability of the support steel pipe 8 during installation, and the installation steering plate 5 can be rotated between the top steering shaft 4 and the connecting tail plate 3, so that the device can be applied to oblique steel pipe supports and horizontal steel pipe angle braces with larger angles, avoiding the tedious operations of cutting, welding, and installation of non-standard parts on the construction site, which is conducive to improving the overall stability of the steel support, speeding up the construction progress, and effectively In order to save resources and protect the environment, an axial force gauge 17 is placed on each side of the inner part of the upper shell 16 at the bottom of the supporting steel pipe 8. The center points of the two axial force gauges 17 and the supporting steel pipe 8 are in a straight line, and each contact surface is flat, ensuring that the stress state of the supporting steel pipe 8 is normally transmitted to the supporting structure through the axial force gauge 17, so as to realize the axial force test of the steel support. When the tested support body is subjected to stress, the axial force gauge 17 will be compressed and deformed, and the upper shell 16 will deform synchronously, which will be transmitted to the steel string and converted into a change in the stress of the steel string, thereby changing the vibration frequency of the steel string, and the electromagnetic coil excites the steel string and The vibration frequency is measured, and the frequency signal is transmitted to the frequency meter via the cable, so that the axial force of the pile body under test can be measured. The axial force meter 17 is placed inside the upper shell 16, and no special welding construction is required, and no special mounting frame is required for fixing. It is convenient, fast, safe and efficient, and has significant economic effects in the project. The ball head 23 is finely processed by a CNC lathe, and the surface finish is high. The sealing performance of the ball head 23 and the installation cavity 22 is good. Before installing the device, fill the surrounding of the ball head 23 inside the installation cavity 22 with sand, and seal the sand mouth 20 tightly. After loading the prestress, the ball The head 23 adapts its angle according to the axial force direction of the supporting steel pipe 8. The device is in a compressed state. After unloading the prestress, the sand mouth 20 is opened, and a gap appears around the ball head 23. There is no need to re-jack the supporting steel pipe 8, and the steel support removal work can be easily completed. The device is simple and easy to operate, avoiding the risk of cutting the parent material due to the difficulty of re-jacking. It is green, environmentally friendly, and energy-efficient. The application of the ball head 23 enables the horizontal force transmission system in the process of removing the concrete support of the foundation pit to be smoothly, quickly, and safely converted to the steel support system, ensuring the safety of the foundation pit and the surrounding environment, and has an overwhelming advantage. Afterwards, the ends of the side support plates 21 are fixedly welded to the fixed mounting plates 25, and the triangular support plates 24 and the fixed mounting plates 25 have stronger support for the supporting steel pipes 8, and the triangular support plates 24 on the right side of the fixed mounting plates 25 are cross-mounted, so that the strength of the triangular support plates 24 is higher, and the embedded steel bars 29 are evenly distributed inside the embedded bottom plate 26, which can increase the structural strength and provide a strong connection force, thereby increasing the overall strength and stability of the structure, and during the installation process, the embedded steel bars 29 and the steel bar sleeves 28 are arranged on the wooden board through the pre-set holes to avoid direct lifting of the steel plate and reduce the overall lifting weight. After the strength reaches the design requirements, the steel plate is lifted and the nuts 27 are tightened to complete the pre-embedded and post-planted construction of the steel plate, thereby solving the problem that the embedded parts cannot be reused and cause waste of materials; Finally, when the installation distance of the devices is uneven or the distance between the devices is too long, the clamp body 10 is installed on the outside of the supporting steel pipe 8, and then different supporting steel pipes 8 are supported and connected by clamp support ribs 15 to improve the structural stability and bearing capacity of the installation device.
