Description

Technical Field

[0001] This utility model relates to the field of ladder cage technology, and in particular to a ladder cage with a prefabricated 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 ladder cage with a prefabricated foundation that does not require on-site foundation construction during use, thereby solving the problems of slow installation speed and waste pollution caused by the existing ladder cages that require on-site foundation construction.

[0004] To achieve the above objectives, this utility model employs the following technology: a ladder cage with a prefabricated foundation, comprising a ladder cage body, the ladder cage body including an outer frame consisting of several detachably connected tubular segments and a ladder disposed within the outer frame, characterized in that it further includes a prefabricated concrete slab, the ladder cage body being connected to the concrete slab via a ladder cage connecting structure, the prefabricated concrete slab having a foundation fixing structure for fixing the prefabricated concrete slab to the ground, each segment including four rectangularly distributed uprights, four upper horizontal bars connecting the upper ends of adjacent uprights one-to-one, and four lower horizontal bars connecting the upper ends of adjacent uprights one-to-one, one upper horizontal bar, one lower horizontal bar, and two uprights forming a rectangular frame structure segment sidewall, the segment sidewall being connected to a frame reinforcement structure. In use, the ladder cage is installed by fixing it to the ground via the foundation fixing structure and the prefabricated concrete slab. This allows for quick installation of the ladder cage on the ground, and no concrete debris is generated when removing the ladder cage.

[0005] Preferably, the frame reinforcement structure includes a circular frame, a horizontal connecting rod connecting the left and right ends of the circular frame, an upper connecting column connecting the upper end of the circular frame to the upper crossbar, and a lower connecting column connecting the lower end of the circular frame to the lower crossbar. This effectively increases the strength of the segmental sidewall frame. The frame reinforcement structure requires only two connection points to the frame of the ladder cage sidewall; fewer connection points result in less damage to the segmental sidewall frame during connection. Existing reinforcement methods using intersecting diagonal braces have more connection points, leading to greater damage to the segmental sidewall frame.

[0006] Preferably, both the upper and lower connecting column heads are connected to the outer circumferential surface of the circular frame, while the horizontal connecting rod is connected to the inner circumferential surface of the circular frame. This improves the compressive and tensile strength of the sidewall reinforcement structure.

[0007] Preferably, the upper end of the segment has an upper connecting lug and the lower end has a lower connecting lug. Adjacent segments are fixed together by segment connecting bolts passing through both the upper and lower connecting lugs and then threaded together with segment connecting nuts. This improves the detachable connection of segments.

[0008] Preferably, the threaded end of the segmental connecting bolt faces downwards. Even if the segmental connecting nut comes loose, the segmental connecting bolt will not fall off and will still serve its fixing function. This results in good reliability when achieving segmental connections.

[0009] Preferably, each of the four sides of the segment is provided with a protective mesh, and the upper end of the protective mesh is provided with a hanging ring. The hanging ring is attached to the segment connecting bolt above the lower connecting lug. This provides better safety protection for the ladder cage.

[0010] Preferably, the ladder cage connection structure comprises four structures located at the four corners of the ladder cage body. Each connection structure includes a metal connecting block welded to the ladder cage body and a ladder cage connecting threaded post cast in a precast concrete slab. The threaded post passes through the metal connecting block and is threadedly connected to a ladder cage connecting nut, thereby fixing the metal connecting block to the precast concrete slab. This provides a specific technical solution for improving the ladder cage connection structure.

[0011] Preferably, the ladder cage body is welded to the upper surface of the metal connecting block. This makes the ladder cage body less likely to damage the precast concrete slab.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] Preferably, the vertical pile extraction plate is equipped with 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.

[0020] 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.

[0021] 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.

[0022] 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
