Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a diagonal brace with a settlement alarm function. Background Technology

[0002] In infrastructure construction projects such as building foundation pit engineering and underground space development, the diagonal bracing arm is the core load-bearing component of the foundation pit support system. It is fixed to the ground via a mounting base, and its top supports the foundation pit wall, thereby balancing the lateral pressure on the wall, preventing foundation pit collapse, and ensuring construction safety and the stability of surrounding structures. However, during foundation pit construction, ground settlement is difficult to avoid due to factors such as groundwater extraction, soil consolidation, and changes in surrounding loads.

[0003] Existing diagonal bracing systems have shortcomings in their design adaptability to ground bearing characteristics and settlement risks in practical applications. They generally lack specific protective structures against ground settlement, lack real-time settlement detection and emergency support mechanisms, and cannot promptly avoid the support risks caused by settlement. This not only compromises the flatness of the bracing installation but also causes deviations in the support force transmission path, leading to uneven stress on the bracing tubes. Therefore, we have designed a diagonal bracing system with a settlement alarm function to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a diagonal brace with a settlement alarm function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a diagonal brace with a settlement alarm function, comprising: The diagonal bracing tube has a support platform fixedly connected to its top and an installation base hinged to its bottom. The support platform acts on the foundation pit wall and transmits the supporting force to the installation base through the diagonal bracing tube. The settlement alarm is fixedly installed on the outer wall of the inclined support pipe to detect ground settlement and issue an alarm. The folding struts are mirror-mounted below the mounting base, and a bidirectional screw is threaded between the two folding struts. When the ground settles, the bidirectional screw drives the folding strut plate to support the mounting base. Telescopic struts, mirror images of folding struts in a cross shape, are positioned below the mounting base to distribute the pressure from the diagonal bracing arms on the folding struts; The load-bearing plate is located below the folding struts and telescopic struts.

[0006] Preferably, the bottom of the mounting base is fixedly connected to a first support, and the top of the folding strut is rotatably connected to the first support.

[0007] Preferably, the folding end of the folding support rod has a threaded hole, the bidirectional lead screw passes through the threaded hole and extends to both ends, and one end of the bidirectional lead screw is fixedly connected to a drive handle.

[0008] Preferably, two second supports are fixedly connected to the outer wall of the first support, and the top of the telescopic strut is rotatably connected to the second supports.

[0009] Preferably, the telescopic support rod includes a fixed rod and a telescopic rod, the telescopic rod is inserted into the fixed rod, and the outer wall of the telescopic rod has a plurality of limiting holes arranged in a linear array.

[0010] Preferably, a limiting frame is fixedly sleeved on the outer wall of the fixed rod, a rotating shaft is fixedly connected to the inner wall of the limiting frame, a limiting plate is rotatably connected to the outer wall of the rotating shaft, and a torsion spring is provided between the limiting plate and the rotating shaft, with the torsion spring sleeved around the rotating shaft.

[0011] Preferably, one end of the limiting plate is configured as a boss, and the boss end of the limiting plate is engaged in the limiting hole to fix the telescopic support rod after telescopic movement.

[0012] Preferably, the load-bearing plate is cross-shaped, and a cross-shaped receiving groove is provided on the top of the load-bearing plate. The bottoms of the folding strut and the telescopic strut are rotatably connected to the inner wall of the receiving groove.

[0013] The technical effects and advantages of this utility model are as follows: This invention utilizes a settlement alarm to detect ground settlement in real time and issue timely warnings, providing valuable time for adjusting the support of the mounting base. Its mirror-shaped folding struts, combined with bidirectional lead screws, can quickly unfold to provide stable support to the mounting base during ground settlement. The cross-shaped mirror-arranged telescopic struts effectively distribute the pressure transmitted from the diagonal bracing arms to the folding struts, preventing localized overload. The cross-shaped load-bearing plate, rotatably connected to the folding and telescopic struts via a receiving groove, significantly increases the contact area with the soil surface. Simultaneously, the balanced force distribution of the cross structure evenly transmits the supporting force to the ground, significantly reducing pressure per unit area and effectively preventing ground subsidence caused by excessive localized stress.

It is used to detect ground settlement and issue an alarm. A folding support rod 5 is mirrored below the mounting base 3. A two-way screw rod 6 is threaded between the two folding support rods 5. When the ground settles, the two-way screw rod 6 drives the folding support plate to support the mounting base 3. A telescopic support rod 7 is mirrored below the mounting base 3 in a cross shape with the folding support rod 5 and is used to disperse the pressure from the inclined support arm on the folding support rod 5. A load-bearing plate 8 is set below the folding support rod 5 and the telescopic support rod 7. The load-bearing plate 8 is used to increase the contact area with the ground.
