Description

Technical Field

[0001] The utility model relates to the technical field of building construction auxiliary equipment, in particular to a multifunctional safety ladder for building construction. Background Art

[0002] Ladders are commonly used climbing tools at construction sites. At present, most of the common ladders used during construction on construction sites are straight ladders, herringbone ladders, telescopic ladders, etc. There are also homemade wooden ladders on some sites. These climbing tools have no anti-rollover measures and have relatively poor stability during use. The unstable loads generated during the operation and the unfavorable environment of the construction site can easily cause instability and overturning, affecting the working status and work safety of construction workers. At the same time, workers must always pay attention to stabilizing their body and reducing shaking during operation, which is neither safe nor convenient. In addition, the existing ladder has a fixed structure and a large size. It is difficult to adapt to environments with a need to climb high and a small space, which affects its applicability. For example, when facing some climbing operations in small spaces such as stairwells and water heating wells, the existing ladder is likely to occupy too much space due to its large size, causing inconvenience to the construction work, and there are also problems such as difficulty in carrying. Generally, a straight ladder can be used to perform operations at higher positions than a herringbone ladder during use, but the use of a straight ladder requires solid and reliable support such as walls and columns, which makes it relatively difficult to work at high places with open space around it. The herringbone ladder can be used for high-altitude operations in open places, but its stability is relatively poor. As the body of the construction workers increases, their center of gravity also increases, and the overall stability and safety are reduced, which is not conducive to construction operations at higher places. At the same time, like a straight ladder, when facing a small space, it occupies too much space due to its large size, which will cause problems such as inconvenience in operation.

[0019] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0020] Example: As shown in the attached Figure 1-5 As shown, the utility model is a multifunctional safety ladder for construction, the whole body of which can be made of aluminum alloy, with light overall weight, high strength, firmness and reliability.

[0021] It includes an end connector 1, both ends of which are provided with a spigot-type ladder step 2, the two spigot-type ladder steps 2 are connected by the end connector 1, and the angle between the two spigot-type ladder steps 2 can be adjusted from 0° to 180°. The vertical beam 22 of the spigot-type ladder step 2 is rectangular throughout its length, and the shape of the vertical beam 22 at the end connector 1 is a square structure, so that when the opening angle between the two spigot-type ladder steps 2 reaches 180°, it can no longer be rotated, and at this time it can be used as a straight ladder, which can be flexibly selected according to the construction environment and construction needs.

[0022] When in use, when the ladder opening (the angle between the two socket-type steps 2) reaches the maximum limit of 180°, it is converted from a herringbone ladder to a straight ladder, combining two forms to better adapt to complex and changeable construction environments, meet construction needs, and improve applicability.

[0023] Preferably, the end connector 1 is an ear plate fixed to one side of the end of the socket-type step 2, and a mounting hole for installing the hinge shaft is provided on the ear plate. When the angle between the two socket-type steps 2 is adjusted to 180°, the end faces of the two socket-type steps 2 abut against each other, which can ensure stability when used as a straight ladder.

[0024] Preferably, each socket-type step 2 includes a plurality of step units and a socket-type connection unit, the upper and lower ends of the socket-type connection unit are plugged with step units, and bolts 21 for locking the step units are provided on the socket-type connection unit. The connection via the bolts 21 facilitates assembly and disassembly.

[0025] Furthermore, the step unit and the socket-type connection unit each include two vertical beams 22 and a horizontal beam 23 disposed between the two vertical beams 22 .

[0026] The socket-type ladder steps 2 are adopted, and the socket-type bolt reinforcement principle is adopted. The ladder can be split, and the steps can be flexibly increased or decreased to change the volume of the ladder. It can be adjusted according to the working environment space and working height requirements to improve applicability.

[0027] The various parts of the socket-type ladder steps 2 are connected by bolts 21 in the middle. The bolts 21 can be removed as needed, and the end near the opening can be removed to reduce the volume of the ladder and better adapt to narrow spaces. The steps can also be increased as needed to appropriately increase the height.

[0028] Reinforcing rods 3 are hinged on the left and right outer walls of the upper part of one of the socket-type steps 2, and a connecting frame 4 adapted to the reinforcing rod 3 is provided on the upper part of the other socket-type step 2. The reinforcing rod 3 and the connecting frame 4 are detachably connected. The reinforcing rod is used to fix the angle between the two socket-type steps 2, fix the two socket-type steps 2, enhance stability, and prevent the four legs of the ladder from sliding against the ground and causing collapse.

[0029] A telescopic fixed leg 5 is provided on the outer side of the end connecting piece 1, and the telescopic fixed leg 5 is hinged to the end connecting piece 1. The length of the telescopic fixed leg 5 can be adjusted according to the height of the ladder, the flatness of the ground and the construction requirements. With the end connecting piece 1 of the ladder as the center, the fan-shaped outward swing is performed to better adjust the angle according to the needs. The telescopic fixed leg 5 extends outward to both sides of the ladder to provide support for both sides of the ladder and bear part of the lateral load. The telescopic fixed leg 5 is adjustable and the length is controllable. It can be adjusted according to actual environmental conditions. Therefore, it also has a certain adaptability to the ground with poor flatness, effectively improving the stability of the ladder.

[0030] Preferably, the end of the socket-type ladder step 2 away from the end connector 1 is provided with a removable rubber anti-slip sleeve 6, which is used to increase the grip of the ladder. After the open end of the ladder is removed, the rubber anti-slip sleeve 6 can also be removed and transferred to the four feet of the small ladder after removal, which will not affect the anti-slip performance of the ladder.

[0031] Preferably, in order to facilitate the storage and use of the reinforcement rod, one end of the reinforcement rod 3 is hinged to the first socket-type step 2 through a hinge 31, and the other end is provided with a hook 32. The connecting frame 4 is a hanging column arranged on the second socket-type step 2, and a hanging member 33 adapted to the hook 32 is provided on the lower side of the hinge 31, and the hanging member 33 is fixed on the first socket-type step 2.
