Description

Technical Field

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

[0002] During construction, it is often necessary to reach different heights of the building from the ground (such as between different floors). The existing method is to build temporary staircases. However, since these staircases are open, people are easily injured by falling objects when climbing them on the construction site, and people with a fear of heights are afraid to climb them. Utility Model Content

[0003] The present invention aims to provide a construction ladder cage that can safely enable construction workers to reach the corresponding height, thus solving the problem of poor safety when using exposed ladders to allow construction workers to ascend buildings under construction.

[0004] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technology: a construction ladder cage, characterized in that it comprises a plurality of ladder cage units connected vertically in sequence, each ladder cage unit comprising a rectangular outer frame and a ladder disposed within the outer frame, the upper and lower ends of the outer frame being open, and a fence provided on the entire outer perimeter of the outer frame to prevent people from falling out of the outer frame, the upper end of the outer frame being provided with an upper support strip extending laterally, the lower end of the outer frame being provided with a lower support strip extending laterally, the ladder being located on one side of the outer frame laterally, the upper end of the ladder being connected to the upper support strip, and the lower end of the ladder being connected to the lower support strip; one of the upper support strip and the lower support strip is located on the front side of the rectangular frame, and the other is located on the rear side of the rectangular frame, and the ladders of adjacent ladder cage units face opposite directions; the lower end of the outer frame is provided with a doorway for entering the lower support strip, and the doorway is provided with an openable door. In use, according to the height requirements during construction, the corresponding number of ladder cage units are stacked and connected together. The door of the corresponding ladder cage unit is opened as needed. The user enters from the doorway of the bottom ladder cage unit, climbs to the corresponding height using the ladder and the upper and lower support strips, and then exits through the corresponding doorway to reach the corresponding height.

[0005] Preferably, the ladder includes two inclined beams distributed in a left-right direction and a tread connecting the two inclined beams; a handrail is provided on the side of the ladder furthest from the outer frame. The structure is simple and offers good safety.

[0006] Preferably, the upper surface of the pedal is an inclined surface with one end lower than the other towards the support frame. This prevents the pedal from sliding backward and improves safety.

[0007] Preferably, the edge of the pedal facing the support frame is provided with a blocking edge to prevent slipping forward.

[0008] Preferably, one side of the ladder in the left or right direction is close to the outer frame, so that the side wall of the outer frame forms the handrail of the ladder. This results in a compact structure and low manufacturing cost.

[0009] Preferably, a step is formed between adjacent ladder cage units, and between the lower support slats of the upper ladder cage unit and the upper support slats of the lower ladder cage unit. In use, after climbing the ladder, one steps onto the upper support slat, then lifts their foot onto the lower support slat of the next ladder cage unit, and continues climbing on the ladder of the next ladder cage unit by walking on the lower support slat. This improves the utilization rate of the upper and lower support slats.

[0010] Preferably, the outer frame includes four vertical columns and a crossbeam connecting the vertical columns located on the same side wall of the outer frame. The four vertical columns form the four edges of the outer frame, and the vertical columns of adjacent ladder cage units are connected one-to-one by four connecting sleeves. Connecting the upper and lower ladder cage units together is convenient and simple.

[0011] Preferably, the connecting sleeve is provided with a support partition, which separates the connecting sleeve into an upper connecting hole and a lower connecting hole. The vertical column located below the connecting sleeve passes through the lower connecting hole, and the vertical column located above the connecting sleeve passes through the upper connecting hole. This allows for active allocation of the insertion depth of the upper and lower vertical columns into the connecting sleeve, facilitating connection.

[0012] Preferably, the vertical column is rectangular, the opening of the connecting sleeve is rectangular, and each of the two adjacent side walls of the upper connecting hole has an upper threaded through hole. An upper straightening bolt, which is tightened against the vertical column passing through the upper connecting hole, is internally threaded into each of the upper threaded through holes. Similarly, each of the two adjacent side walls of the lower connecting hole has a lower threaded through hole. A lower straightening bolt, which is internally threaded into each of the lower threaded through holes, is tightened against the vertical column passing through the lower connecting hole. The heads of both the upper and lower straightening bolts are located on the outer surface of the outer frame. The vertical columns can be aligned by tightening the upper and lower straightening bolts. Rotating the straightening bolts is convenient.

[0013] Preferably, one side of the door is hinged to the outer frame in the horizontal direction, and the other side has a connecting ring. The outer surface of the outer frame has a connector that passes through the connecting ring. The connector has a connecting through hole extending vertically, and a pin passes through the connecting through hole. The upper end of the pin has a hanging rod for suspending the pin on the connecting through hole. In use, the pin is removed, and then the door is opened by rotating it around the hinge. This makes it convenient to keep the door closed.

[0014] Beneficial effects: It provides a safe platform for construction workers to climb buildings, and the height can be adjusted as needed. Attached Figure Description
