Description

Technical Field

[0001] The invention relates to the technical field of construction ladders, in particular to a ladder used for engineering construction. Background Art

[0002] Steel structure engineering is a structure made mainly of steel. It is one of the main types of building structures. The characteristics of steel are high strength, light weight, good overall rigidity, and strong deformation ability. In the process of climbing operations, relevant equipment and tools are needed. If it is only a repair operation, a mobile lifting platform is generally used. However, for long-term construction, ladders are usually set up to facilitate construction workers to climb up and down.

[0003] The existing steps of installing a ladder are to fix the ladder to a building, such as the upper end of a column, and then use a strap to wrap around the column to fix the ladder. Although the strap is fastened at the beginning, after a long time, the strap will loosen, and further, the stability of the ladder will be greatly reduced. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a climbing ladder for engineering construction, comprising a ladder and a fixing member fixedly connected to the back of the ladder. The fixing member is used to fix the ladder on a building, such as a circular or rectangular column of a steel structure.

[0005] The ladder comprises two vertically arranged vertical rods, a plurality of groups of horizontal rods are fixedly connected between the two vertical rods, and each group of horizontal rods is provided with at least two rods, the axis connecting the adjacent rods forms an acute angle with the horizontal plane, and the user steps on the horizontal rods and leans his body toward the ladder. During the climbing process, the center of gravity of the user's body is toward the ladder, which can improve the safety of use.

[0006] The fixing member comprises a connecting rod, both ends of which are provided with an adjustment frame, a screw rod is threadedly connected between the adjustment frame and the connecting rod, and the threads at both ends of the screw rod have opposite rotation directions. By rotating the screw rod, the adjustment frame can be moved closer to or away from the connecting rod.

[0007] Preferably, a hook is fixedly connected to the upper side wall of the vertical rod, which is used to hang the ladder on the building and is the main force-bearing member in the vertical direction.

[0008] Preferably, the acute angle is in the range of greater than 0° and less than 15°, that is, selecting a suitable acute angle is more conducive to climbing while ensuring safety.

[0009] Preferably, a fixing frame is fixedly connected to the connecting rod, and a rubber pad is fixedly connected to the side wall of the fixing frame. The use of the rubber pad can prevent the fixing frame from rigidly contacting the building and causing rigid damage to the building.

[0010] Preferably, the fixing member further comprises a strap, and the strap passes through the adjustment frame and the fixing frame, that is, the ladder is tightly fixed to the surface of the building by the strap, which makes it more stable during climbing.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. An adjustment frame and a screw are provided. After the strap is tied and fixed, the screw can be rotated so that the adjustment frame pulls the strap, thereby tightening the strap. That is, during long-term use, the strap can be tightened to improve the stability of the ladder fixation and increase the safety of the ladder use.

[0013] 2. The horizontal bar is tilted, and when the user climbs, his body can lean toward the direction of the ladder, so that the user and the ladder are closer, thereby improving safety during the climbing process. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. Embodiment 1

[0022] like Figure 1As shown, a ladder for engineering construction comprises a ladder 1 and a fixing member 2 fixedly connected to the back of the ladder 1. The ladder is attached to a building, such as a steel structure building, such as a column, to facilitate construction workers to climb up the column to carry out construction. The ladder 1 is the main structure of the ladder, that is, the climbing component of the construction workers, and the fixing member 2 fixes the ladder 1 to the column, thereby improving the stability of the ladder 1 and improving the safety of the ladder.

[0023] Combination Figure 2 and Figure 4 As shown, the ladder 1 includes two vertically arranged vertical rods 11, which are main components for vertical force bearing, and a plurality of groups of cross rods 12 are fixedly connected between the two vertical rods 11, and the cross rods 12 are used for climbing, and each group of cross rods 12 is provided with at least two rods, and the axis line connecting the adjacent rods forms an acute angle with the horizontal plane, such as Figure 4 As shown, the acute angle is represented by α, and the user steps on the crossbar 12 and leans his body toward the ladder 1, that is, the user's body center of gravity leans toward the ladder 1, which is conducive to the body and the ladder being closer, thereby improving the safety of climbing.

[0024] Furthermore, the surface of the cross bar 12 is provided with an anti-slip treatment to avoid slipping, and the value of α should not be too large to also avoid slipping.

[0025] like Figure 3 As shown, the fixing member 2 includes a connecting rod 21, which is a rod and a connecting block is arranged on the rod, and the connecting block is fixedly connected to the vertical rod 11. Here, the connecting block is preferably fixed by welding. If the fixing member 2 is designed to be adjustable up and down, it can be fixed by threaded connection. Adjustment frames 23 are arranged at both ends of the connecting rod 21. A screw 22 is threadedly connected between the adjustment frame 23 and the connecting rod 21. The threads at both ends of the screw 22 have opposite rotation directions, that is, rotating the screw 22 can achieve the distance between the adjustment frame 23 and the connecting rod 21.

[0026] like Figure 2 As shown, the upper side wall of the vertical rod 11 is fixedly connected with a hook 13. The hook 13 is a rod with one end bent into a semicircle, and the hook 13 hooks the upper part of the column to achieve the fixation of the ladder in the vertical direction.

[0027] like Figure 4 As shown in FIG. 1 , the acute angle ranges from greater than 0° to less than 15°. A suitable angle can improve the safety of ladder climbing.

[0028] like Figure 3As shown, a fixing frame 25 is fixedly connected to the connecting rod 21, and a rubber pad 26 is fixedly connected to the side wall of the fixing frame 25. When the ladder is installed and fixed, the fixing frame 25 contacts the surface of the column to prevent the fixing frame 25 from damaging the surface of the column. Therefore, a rubber pad 26 is additionally provided. At the same time, the rubber pad 26 contacts the column and also provides friction.

[0029] The fixing member 2 also includes a strap 24, which passes through the adjustment frame 23 and the fixing frame 25. That is, after the ladder is fixed to the column, the strap 24 needs to be used to further fix the ladder to prevent the slide from shaking. The strap 24 is used to fix the ladder. After the strap 24 passes through the adjustment frame 23 and the fixing frame 25, the strap 24 is tightened, and then the screw 22 is rotated to move the adjustment frame 23 toward the connecting rod 21, thereby further tightening the strap 24, thereby improving the stability of the ladder fixation. Embodiment 2

[0030] This embodiment is different from the first embodiment in that the cross bar 12 is a flat bar, and the inclination angle of the plate is α. This arrangement can increase the contact area of ​​the user stepping on the cross bar 12, making the user climb more comfortably. Embodiment 3

[0031] This embodiment is different from the first embodiment in that a screw member is fixedly connected to one side of the fixed frame 25, and the screw member is threadedly connected to the connecting rod 21. During installation, the fixed frame 25 can be rotated, and then the distance between the fixed frame 25 and the connecting rod 21 can be adjusted to achieve distance control between the ladder 1 and the column, preventing the ladder 1 from being too close to the column, which is not conducive to the soles of the feet stepping on the crossbar 12 comfortably and safely.
