The connecting structure does not affect the normal stress state of the steel support, and solves the problem that the conventional support structure can only bear pressure but cannot bear tension.

Description

Technical Field

[0001] This invention belongs to the field of steel cofferdam support and deep foundation pit support, and in particular relates to a damped steel pipe support structure that can withstand tension and compression. Background Technology

[0002] The foundation pit support structure system mainly consists of retaining piles (or retaining walls), capping beams, internal bracing, lintel beams, column piles, and columns. Internal bracing is an extremely important component of the foundation pit support structure. Traditional steel pipe bracing structures often use prestressed connections at the movable ends, which can only utilize the compressive strength of the steel pipe bracing. However, in some steel cofferdams and deep foundation pit support processes, the support components are often in alternating states of tension and compression. Traditional support structures cannot provide support when under tension, resulting in poor structural stability and a high risk of "bracing collapse" accidents. Therefore, it is necessary to make technical improvements to solve the problem that existing support structures can only withstand compression and not tension. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a damped steel pipe support structure that can withstand tension and compression.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows: A damped, tension- and compression-resistant steel pipe support structure includes a cap beam and a steel pipe support below it, which are fixed together by several bolts. A connecting plate is provided at the top of the steel pipe support. Each bolt passes through both the cap beam and the top connecting plate of the steel pipe support. The bolt portion extends upward and outward from the cap beam and is locked by a nut. Steel pads are provided on both the upper and lower sides of the cap beam at the corresponding bolt connection positions. A damping element is provided between the upper steel pad and the nut, and a support seat is provided between the damping element and the nut. Several limiting steel plates are provided between the outer wall of the steel pipe support and the connecting plate.

[0005] Furthermore, each limiting steel plate is evenly distributed around the axis of the steel pipe support.

[0006] Furthermore, the support base has a hole in the middle and is fitted with a bolt.

[0007] Furthermore, the damping element includes a spring that is fitted onto the bolt, with its upper end abutting against a support seat on the lower side of the nut and its lower end abutting against a steel pad.

[0008] Furthermore, the upper end of the bolt's thread is locked by a counternut.

[0009] Furthermore, a pin hole is provided radially at the end of the bolt shank, and a detachable limit pin is inserted into the pin hole.

[0010] Furthermore, the limiting steel plate is made into a trapezoidal structure that is narrower at the bottom and wider at the top.

[0011] Compared with existing technologies, the present invention has the following advantages: The damping element in this invention compresses to provide damping when the steel pipe support structure is under tension. When the steel pipe support returns to the compressed state, the spring re-expands, restoring the steel pipe support to its compressed state. This connection structure does not affect the normal stress state of the steel support, solving the problem that conventional support structures can only withstand compression and not tension. Furthermore, the main components of this steel pipe support structure are connected by bolts, making installation and disassembly convenient. The components can be reused, resulting in high economic benefits. Attached Figure Description

[0015] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

[0016] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] A damped steel pipe brace structure capable of withstanding tension and compression, such as Figures 1 to 3 As shown, it includes a crown beam 3 and a steel pipe support 4 on its lower side, which are fixed together by several bolts 1. A connecting plate is provided on the top of the steel pipe support. Each bolt passes through both the crown beam and the connecting plate 11 on the top of the steel pipe support. The screw part extends upward and outward from the crown beam and is locked by a nut 10. Steel pads are provided on both the upper and lower sides of the crown beam at the corresponding bolt connection positions. A damping element is provided between the upper steel pad 5 and the nut, and a support seat 12 is provided between the damping element and the nut. Several limiting steel plates 6 are provided between the outer wall of the steel pipe support and the connecting plate.

[0018] The damping component includes a spring 2, which is fitted onto a bolt. The upper end of the spring abuts against a support seat below the nut, and the lower end abuts against an upper steel pad. A long bolt passes through the crown beam and connects the crown beam to the steel pipe support. The spring is compressed when the steel pipe support is under tension and stretched when it is under compression. The limiting steel plate is used to restrict the displacement of the steel pipe support.

[0019] In an optional embodiment, a buffer plate 8 is provided between the connecting plate and the lower steel pad 7. For example, the buffer plate is made of rubber or nylon. The buffer plate can provide a certain buffering effect when the steel pipe support structure is under tension and compression, resulting in better overall structural stability and safety. The limiting steel plate is made into a trapezoidal structure that is narrower at the bottom and wider at the top, serving functions such as positioning and support. The upper and lower steel pads provide a flat support surface, increase the stress area, stabilize the structure, and together with the limiting steel plate, prevent the steel pipe support structure from shifting or falling off under accidental minor collisions.

[0020] Each limiting steel plate is evenly distributed around the axis of the steel pipe support. A hole is opened in the center of the support base, and a bolt is fitted into it. The upper end of the spring can be fixed to the bottom of the support base. The upper end of the bolt is locked by a countersunk nut. A pin hole is radially opened at the end of the bolt, and a limiting pin 9 is detachably inserted into the pin hole to prevent the nut from falling out, effectively ensuring the reliability of the connection between the crown beam and the steel pipe support.

[0021] In an optional embodiment, a sensor for detecting the height of the support is provided at the support base or on the upper side of the cap beam. When the cap beam or steel pipe support tilts, the sensor will feed the displacement information back to the computer control system. The staff can understand the working status of the steel pipe support structure in real time, and can set an over-limit alarm device. Once the sensor detects that the displacement exceeds the safety value, it will issue a warning or directly alarm to remind the staff to handle it, making the steel pipe support structure work more safely and reliably.

[0022] This invention features a rationally designed structure that can withstand both compression and tension. The damping components compress to provide damping when the steel pipe support structure is under tension, and the springs re-expand when the steel pipe support returns to a compressed state. This connection structure does not affect the normal stress state of the steel support, solving the problem that conventional support structures can only withstand compression and not tension. Furthermore, the main components of this steel pipe support structure are connected by bolts, making installation and disassembly convenient. The components can be reused, resulting in high economic benefits.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
