Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a construction ladder with a protective structure for building engineering. Background Art

[0002] A construction project refers to an engineering entity formed through the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment; a construction ladder is a commonly used tool in construction projects. Temporary installation of construction ladders in construction sites can build a temporary passage for construction workers, making it convenient for construction workers to work at heights and improving work efficiency.

[0003] Prior art includes a utility model with publication number CN218177137U, which discloses a construction ladder for construction engineering with a protective structure. The patent adopts a ladder with a pedal integrated on the inner side of the ladder, a non-slip pad fixedly connected to the pedal, and an airbag fixedly connected to one side of the ladder. The advantages of the utility model are: the bottom of the card plate fits the ground to support the ladder again, and the stop pin is rotated to block it on one side of the card plate, so that the card plate is stuck in the card slot in cooperation with the pointed head, and the contact area and friction between the ladder and the ground are increased in cooperation with the bottom plate and the oblique teeth, and the oblique teeth prevent the ladder from sliding. The airbag plays a role in supporting and preventing the ladder from sliding, so that the ladder can better prevent itself from slipping and protect the personal safety of the construction workers; even if the ladder slides, the airbag will play a buffering role and will not injure the workers, thereby protecting the workers. Therefore, the ladder has high safety during construction, and solves the problem that in construction sites, there are many potholes in the treated soil foundation, and thicker iron plates are often laid here to carry vehicles and people, and the surface of the iron plates is relatively smooth. When the construction ladder is supported on the iron plate, the ladder is easy to slide and fall to the ground, causing danger to the workers on the ladder.

[0004] In the process of carrying out construction work at a high place on the construction site with the help of a construction ladder, there is an existing construction ladder such as the above-mentioned one that improves the stability of the ladder when in use by providing a support member at the ladder foot. Since the design angle of the support member is constant, the ladder can only be used at the designed angle. However, due to the complex environment of the construction site, when working with the help of a construction ladder, the placement angle of the construction ladder will change according to the needs. When the support member is designed with a constant angle, it will interfere with the placement of the construction ladder, resulting in a problem of reduced applicability of the construction ladder. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that when working with the help of a construction ladder, the placement angle of the construction ladder will change according to the needs.

A construction ladder with a protective structure for construction engineering is proposed to solve the problem.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a construction ladder for construction engineering with a protective structure, comprising a bracket, a crossbar and a reinforcement assembly, wherein the crossbar is fixedly connected to the side surface of the bracket, and the reinforcement assembly is arranged on the surface of the bracket;

The knob installed on the side of the threaded rod can be operated by construction workers with the cooperation of the handle, thereby facilitating the construction workers to control the rotation of the threaded rod.

[0011] Preferably, the abutment plate abuts against the side surface of the bracket, and there are two T-shaped sliders, which are symmetrically arranged with respect to the cross bar. The moving direction of the U-shaped block can be guided by the T-shaped slider installed inside the bracket to ensure that the U-shaped block is in the same direction when moving.
