[0027] Embodiment: This embodiment aims to provide an assembled ladder cage, the main function of which is reflected in high assembly efficiency and short time consumption, which can effectively speed up the construction progress of the bridge.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , including: a rectangular frame, the rectangular frame is composed of a vertical beam, a horizontal beam 2, a reinforcing rib 3 and a staircase 4, there are four vertical beams in total, each vertical beam is composed of three sections of columns 1 butted end to end, and correspondingly, the staircase 4 is also provided with three layers, both ends of the column 1 are welded and fixed with a circular butt plate 5, the side of the butt plate 5 is evenly distributed along the circumferential direction. Four semi-cylinders 6 are distributed at equal intervals on the side of the butt plate 5, and two adjacent semi-cylinders 6 are perpendicular to each other, that is, the four semi-cylinders 6 are cross-shaped as a whole, the two adjacent butt plates 5 are tightly fitted, and the semi-cylinders 6 on the sides of the two tightly fitted butt plates 5 correspond to each other one by one, thereby the two adjacent butt plates 5 are tightly fitted so that the corresponding semi-cylinders 6 can form a complete cylinder 7.

[0029] Reference Figure 1 , Figure 3 and Figure 4, the upper and lower ends of the vertical beam are provided with circular auxiliary connecting plates 8, the auxiliary connecting plates 8 have the same size specifications as the docking plates 5, and the side surfaces of the auxiliary connecting plates 8 are also evenly distributed along the circumferential direction. The auxiliary connecting plate 8 at the lower end of the vertical beam fits tightly with the docking plate 5 at the lower end of the lowest column 1, and the semi-cylinders 6 on the sides of the two correspond to each other to form a complete cylinder 7; the auxiliary connecting plate 8 at the upper end of the vertical beam fits tightly with the docking plate 5 at the upper end of the uppermost column 1, and the semi-cylinders 6 on the sides of the two correspond to each other to form a complete cylinder 7, thereby ensuring that the top and bottom components of the rectangular frame are assembled The stability of the installation; wherein, the docking plate 5 at the upper end of the column 1 and the middle part of the top surface of the auxiliary connecting plate 8 are both provided with a positioning hole 11, and the docking plate 5 at the lower end of the column 1 and the middle part of the bottom surface of the auxiliary connecting plate 8 are both provided with a protruding column 12 downward, and the protruding column 12 and the positioning hole 11 are convenient for the staff to quickly dock the multi-section column 1; the protruding column 12 on the auxiliary connecting plate 8 at the lower end of the vertical beam is used to raise the bottom of the rectangular frame to facilitate the staff to install the bolts, and the protruding column 12 on the auxiliary connecting plate 8 at the upper end of the vertical beam is used to facilitate the staff to align the auxiliary connecting plate 8 with the docking plate 5 below.

[0030] Reference Figure 1 and Figure 2 Four cross beams 2 are equidistantly arranged between each two adjacent vertical beams in the height direction. The cross beams 2 are actually steel pipes. The ends of the two middle cross beams 2 are both oriented toward the joints of the two adjacent docking plates 5, and the ends of the two top and bottom cross beams 2 are both oriented toward the joints of the auxiliary connecting plates 8 and the adjacent docking plates 5, so that the ends of the cross beams 2 can be sleeved on the outside of the corresponding cylinders 7 and the two can be fixed together with bolts; an X-shaped reinforcing rib 3 is arranged between the two upper and lower adjacent cross beams 2, and a sleeve hole is arranged at the end of the reinforcing rib 3, through which the end of the reinforcing rib 3 is sleeved on the outside of the corresponding cylinder 7, and bolts are installed on the cylinder 7 to prevent the reinforcing rib 3 from falling off the cylinder 7 by the bolts. It is known that the fixing method of the reinforcing rib 3 and the cross beam 2 is different.

[0031] Reference Figure 1 , Figure 5 and Figure 6 The stairs 4 are located in a rectangular frame and supported by the crossbeam 2. Specifically, the number of stairs 4 corresponds to the number of columns 1, and there are three layers. The high and low ends of each layer of stairs 4 are provided with platform plates 9. The end of the platform plate 9 away from the stairs 4 is provided with a semi-annular hanging plate 10. The hanging plate 10 is placed on the corresponding crossbeam 2 and fixed by bolts. The hanging plate 10 is set to be arc-shaped in order to better fit the shape of the crossbeam 2, so that the position of the stairs 4 can be fixed in advance, which is convenient for the staff to install bolts between the hanging plate 10 and the crossbeam 2 below it.

[0032] When assembling, refer to Figure 1, prepare two vertical beams and lay them flat on the ground, and install auxiliary connecting plates 8 at both ends of the vertical beams, then install four cross beams 2 at the correct position between the two vertical beams, repeat this operation once, at this time, the front and rear side structures of the rectangular frame have been initially formed, the next step is to install the left and right side cross beams 2 on the front side structure of the rectangular frame, and then combine the rear side structure of the rectangular frame with the left and right side cross beams 2. At this time, the overall frame prototype of the rectangular frame has been formed, and the rectangular frame is erected by the lifting equipment, and then the stairs 4 and reinforcement ribs 3 can be installed layer by layer from bottom to top. During use, the staff can use the space left by the X-shaped reinforcement ribs 3 to enter the first floor stairs 4, eliminating the installation steps of the door body.

[0033] In this embodiment, the composition of the vertical beam is extremely simple. It is only necessary to stick the three sections of the column 1 end to end together. This method does not require the use of bolts to completely fix the three sections of the column 1 together. It is only necessary to temporarily ensure that the three sections of the column 1 are not disconnected from each other to ensure that the subsequent cross beams 2 and reinforcement ribs 3 can be installed smoothly. After the cross beams 2 and reinforcement ribs 3 are installed, the adjacent columns 1 are automatically and stably connected under the constraints of the cross beams 2 and reinforcement ribs 3.

[0034] The ladder cage provided in this embodiment has fewer assembly steps and high assembly efficiency, which effectively saves working time and speeds up the construction progress of the bridge.

[0035] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
