Description

Technical Field

[0001] This utility model belongs to the field of building foundation pit construction technology, and in particular relates to a steel unlocking component for foundation pit support in building engineering. Background Technology

[0002] Foundation pit support steel is an important structure used in construction engineering to support and protect the soil around the foundation pit, prevent it from collapsing or deforming, and ensure the safety of foundation pit construction. Through its own strength and rigidity, foundation pit support steel can withstand the lateral pressure of the soil, limit the displacement of the soil, maintain the stability of the slope, and prevent the soil from collapsing and causing harm to construction personnel and the surrounding environment.

[0003] In foundation pit support operations, the use of steel profiles in conjunction with concrete protective layers and pre-embedded anchors can effectively enhance the stability of the soil on the sidewalls of the foundation pit and ensure the safety of foundation pit construction. However, during the dismantling of the steel profiles, it is necessary to manually remove the connecting parts between the steel profiles and then use hoisting equipment to lift and dismantle the steel profiles. Construction workers operate in a narrow and dangerous space around the foundation pit, which is labor-intensive and has extremely low dismantling efficiency. Therefore, it is necessary to provide a steel profile unlocking component for foundation pit support in construction engineering that can provide temporary support for easy installation and automatically unlock during hoisting for easy dismantling of foundation pit support steel profiles.

[0021] In the following description, an embodiment of the present invention, a steel unlocking component for foundation pit support in building engineering, will be described with reference to the accompanying drawings.

[0022] Figure 1-4 This invention illustrates an embodiment of a foundation pit support steel unlocking assembly in construction engineering, comprising a support sleeve 2 welded to the surface of an upper steel section 1; a locking assembly 3 is provided at the bottom of the support sleeve 2, the locking assembly 3 including locking hooks 31 located on both sides of the support sleeve 2, a threaded sleeve 11 welded to the rear side of the bottom of the locking hook 31, a bolt 12 threadedly connected to the inner cavity of the threaded sleeve 11, the top end of the bolt 12 penetrating into the inner cavity of the locking hook 31 and tightly fitting against the bottom of the lower steel section 4, and the two locking hooks 31 are connected together. A rotating column 32 is welded to the top of the locking hook 31. The rotating column 32 is rotatably connected to the inner cavity of the locking hook 31. Torsion springs 33 are sleeved on both sides of the surface of the rotating column 32. One end of the torsion spring 33 is welded to the locking hook 31, and the other end of the torsion spring 33 is welded to the support sleeve 2. An ear plate 34 is welded to the front side of the locking hook 31. A hanging column 35 is connected between the two ear plates 34. A lower steel section 4 is provided below the upper steel section 1. A pre-embedded anchor rod 8 is installed through the upper steel section 1 and the lower steel section 4. The rear end of the pre-embedded anchor rod 8 is inserted through the lower steel section 1. A concrete protective layer 7 is embedded inside the earthen wall. The front end of the pre-embedded anchor rod 8 extends to the front side of the upper steel section 1 and is threadedly connected to a nut 10. A baffle 9 is fitted on the front side of the surface of the pre-embedded anchor rod 8. The front side of the baffle 9 is tightly fitted with the nut 10, and the rear side of the baffle 9 is tightly fitted with the front sides of the upper steel section 1 and the lower steel section 4. Through the combined use of the pre-embedded anchor rod 8, the baffle 9, and the nut 10, the upper steel section 1 and the lower steel section 4 are clamped and fixed, thereby stabilizing the upper steel section 1 and the lower steel section 4. The support is fixedly installed on the surface of the concrete protective layer 7 to support the concrete protective layer 7 and the earthen wall surface. The bottom of the lower steel 4 is engaged with the support seat 5. Anti-detachment nails 6 are welded to both ends of the rear side of the support seat 5. The concrete protective layer 7 is laid on the rear side of the upper steel 1 and the lower steel 4. The anti-detachment nails 6 penetrate the concrete protective layer 7 and are embedded in the earthen wall. Through the setting of the anti-detachment nails 6, the support seat 5 plays a supporting and positioning role, thereby enabling the support seat 5 to stably support and position the lower steel 4.

[0023] Working Principle: In use, the user inserts the anti-detachment nail 6 into the soil wall from the surface of the concrete protective layer 7 to provide temporary support for the support base 5. Then, the lower steel section 4 is suspended in the inner cavity of the support base 5. The user then hangs the crane hook in the inner cavity of the lifting column 35 to lift the upper steel section 1. During lifting, the locking hook 31 rotates upward under the weight of the upper steel section 1, while the torsion spring 33 is compressed. After the upper steel section 1 moves above the pre-embedded anchor rod 8, the crane hook is removed. Under the weight of the locking hook 31 and the torsion of the torsion spring 33, the locking hook 31 rotates downward, thus engaging with the surface of the lower steel section 4, clamping the upper steel section 1 and the lower steel section 4. The user rotates bolt 12 to compress the lower steel section 4, thereby tightly clamping the upper steel section 1 and the lower steel section 4. Then, the user places baffle 9 on the surface of the pre-embedded anchor rod 8 and compresses baffle 9 with nut 10, so that the upper steel section 1 and the lower steel section 4 are stably installed on the surface of the concrete protective layer 7. During dismantling, the user first loosens nut 10. Then, when the upper steel section 1 is lifted and dismantled by the crane, the lifting column 35 is pulled upward and rotates, causing the locking hook 31 to rotate around its stable connection with the support sleeve 2 as the center of rotation. This causes the locking hook 31 to disengage from the bottom of the lower steel section 4, releasing the clamping and fixing of the lower steel section 4, thus achieving automatic unlocking during the lifting and dismantling process.

[0024] In summary, this type of steel unlocking component for foundation pit support in construction engineering provides temporary support for the lower steel 4 through the setting of the support base 5. Subsequently, with the cooperation of the support sleeve 2 and the locking component 3, the upper steel 1 and the lower steel 4 are temporarily clamped and supported. Through the cooperation of the crane and the locking component 3, the upper steel 1 and the lower steel 4 are automatically unlocked and dismantled, thus achieving the purpose of easy installation of temporary support and easy automatic unlocking and dismantling during hoisting.
