Description

Technical Field

[0001] This utility model relates to the field of ladder cage technology, and in particular to a prefabricated ladder cage foundation. Background Technology

[0002] A ladder cage is a commonly used construction tool in building construction. It includes the ladder cage body, which comprises an outer frame consisting of several detachably connected tubular sections, and a ladder housed within the outer frame. When using a ladder cage, a foundation needs to be poured at the location where it will be used for installation. Existing foundations are cast-in-place on the ground, which not only slows down the installation process but also requires re-pouring the foundation when moving the ladder cage from one location to another. This results in concrete residue remaining at the site of the ladder cage's use, causing environmental pollution. Utility Model Content

[0003] The present invention aims to provide a movable prefabricated foundation for fixing ladder cages, which solves the problems of slow installation speed and waste pollution caused by the need to make foundations on site when using existing ladder cages.

[0004] To achieve the above objectives, this utility model employs the following technology: a precast foundation for a ladder cage, characterized in that it includes a precast concrete slab, wherein the precast concrete slab is provided with a foundation fixing structure for fixing the precast concrete slab to the ground and a ladder cage fixing structure for fixing the ladder cage to the precast concrete slab, wherein the ladder cage connecting structure includes a metal connecting block for welding onto the ladder cage body and a ladder cage connecting threaded post cast into the precast concrete slab, wherein the ladder cage connecting threaded post passes through the metal connecting block and is threadedly connected to the ladder cage connecting nut, thereby fixing the metal connecting block to the precast concrete slab.

[0005] Preferably, the cage body is welded to the upper surface of the metal connecting block. This makes the cage body less likely to damage the precast concrete slab.

[0006] Preferably, the lower end of the threaded column connecting the ladder cage is provided with a large-diameter section of the threaded column that abuts against the lower surface of the precast concrete slab. This improves the reliability of the connection between the threaded column connecting the ladder cage and the concrete.

[0007] Preferably, the foundation fixing structure has at least three parts, including a vertical through hole in the precast concrete slab, a threaded sleeve cast in the vertical through hole, and a vertical stake threaded into the threaded sleeve for anchoring in the ground. In use, the vertical stake is rotated to achieve the desired depth of insertion into the ground. This allows the vertical stake to be removed independently while maintaining reliable fixation to the precast concrete slab.

[0008] Preferably, the vertical pile includes a smooth rod section that can pass through the threaded sleeve, a threaded section connected to the upper end of the smooth rod section, and a prism section connected to the upper end of the threaded section. The threaded section is threadedly connected to the threaded sleeve, thereby fixing the vertical pile within the threaded sleeve. The process of fixing the vertical pile is as follows: the vertical pile is inserted into the threaded sleeve, then the vertical pile is tapped to insert the smooth rod section, and then the vertical pile is rotated by using a wrench to engage the threaded section with the threaded sleeve, allowing the vertical pile to be further inserted into the ground to meet the protection requirements.

[0009] Preferably, the threaded section has a large-diameter section, forming a cable-locking step between the large-diameter section and the threaded section. When pulling out the vertical pile, first rotate the pile until the threaded section disengages from the threaded sleeve, then tie a rope to the part of the vertical pile below the large-diameter section, and pull the pile out of the ground using the lifting cable. This method allows for rapid extraction of the vertical pile; if the entire vertical pile is threaded, it can only be extracted by full rotation, which is slower.

[0010] Preferably, the lower end of the threaded sleeve is provided with a support ring that supports the lower surface of the precast concrete slab. This improves the reliability of the connection between the precast concrete slab and the threaded sleeve.

[0011] Preferably, the length of the threaded sleeve is greater than the thickness of the precast concrete slab. This allows for a greater number of threads within the threaded sleeve, ensuring the connection strength between the threaded sleeve and the vertical pile even when the precast concrete slab is thin.

[0012] Preferably, the system also includes a vertical pile extraction plate, on which the upper ends of all the vertical piles are inserted. A pile extraction nut located on the vertical pile extraction plate is threaded onto the threaded tube. In use, after the threaded section disengages from the threaded sleeve, the vertical pile extraction plate is lifted to extract all the vertical piles at once, resulting in high extraction efficiency.

[0013] Preferably, the vertical pile extraction plate is connected to a lifting ring. In use, the vertical pile extraction plate is lifted by dropping it onto the lifting ring, making it convenient to apply force.

[0014] Preferably, the vertical pile extraction plate is provided with a threaded hole, and the lifting ring is provided with a threaded connector. The threaded connector is threaded into the threaded hole, thereby fixing the lifting ring to the vertical pile extraction plate. This provides a connection method between the lifting ring and the vertical pile connecting plate.

[0015] Preferably, the lower surface of the vertical pile extraction plate is provided with a protrusion, and the threaded hole passes through the protrusion. This ensures the connection strength between the lifting ring and the vertical pile extraction plate even when the vertical pile extraction plate is thin.

[0016] Beneficial effects: It comes with its own foundation, so there is no need to pour a foundation on site during installation. The installation speed is fast and there is no waste pollution. Attached Figure Description
