Description

Technical Field

[0001] The utility model relates to the field of building appliances, in particular to a connecting piece for a steel pedal. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Scaffolding is often used in construction. After being assembled and built with fasteners and steel pipes, wooden boards are used to overlap the steel pipes to form a platform. With the development of the industry, traditional wooden boards are replaced with steel pedals, and multiple steel pedals are buckled on the steel pipes to form a working platform. Due to factors such as the specifications of the steel pedals and the reasonable errors in the construction of the steel pipes on the construction site, the existing steel pedals are not perfectly matched with the steel pipe construction on the construction site after assembly, resulting in gaps between the two sides of the steel pedals and the steel pipes on both sides or gaps between the steel pedals. As for the above gaps, first of all, it will affect the stability between the steel pedals and the overall safety of the scaffolding.

[0004] For the existing fasteners for fixing the steel pedal, such as application number CN201820907149.1, which is called a splint fastener, this device is used to limit the steel pedal on the steel pipe below the steel pedal. For this device, the disadvantages are: first, it is inconvenient to install, requiring two people to install it simultaneously on the upper and lower floors, and the installation space is small; secondly, this device has little contact with the steel pedal, and once the bolts become loose, it will still cause displacement and looseness between adjacent steel pedals. A device is needed to solve this problem. Utility Model Content

[0020] 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.

[0021] The utility model is a connecting piece for a steel pedal, as shown in the accompanying drawing of the specification. Figure 1 As shown, the main structure includes a positioning groove 1, a limiting member arranged on the positioning groove 1, and a pre-tightening member arranged on the positioning groove 1;

[0022] First, the limiter is described. The limiter is used to limit the bottom edges of two adjacent steel pedals at the same time and is adjusted according to the distance between the two steel pedals, as shown in the attached figure of the specification. Figure 1 and Figure 2 As shown, the limiting member includes two limiting grooves 4 and a connecting plate 5;

[0023] The two limit grooves 4 are symmetrically arranged with the stud 2 described below as the center. The limit grooves 4 are used to limit the steel pedal bottom plate 7, so the width of the limit grooves 4 is adapted to the bottom edge of the steel pedal, the spacing between the two limit grooves 4 is the same as the target steel pedal spacing, and the spacing between the two limit grooves 4 can be adjusted to adapt to the target spacing between the two steel pedals. The structure is as follows: the connecting plate 5 is connected to the side of the positioning groove 1 by bolts, and a plurality of threaded holes are arranged in an array on both sides of the positioning groove 1. The position of the limit groove 4 is adjusted according to the spacing of the threaded holes, thereby realizing the control of the spacing between the steel pedals.

[0024] As for the preloaded part, the preloaded part includes a stud 2 and a limit seat 3. The stud 2 of the preloaded part is connected to the positioning groove 1 by a thread. By screwing the stud 2 and utilizing the tensile stress between the bolt and the positioning groove 1, the steel pedal bottom plate 7 is limited inside the limit groove 4, thereby limiting the distance between two adjacent steel pedals. However, after the steel pedal is limited, the bolt will remain on the top of the steel pedal and increase the contact area between the bottom of the bolt and the steel pedal. Therefore, a limit seat 3 is provided at the bottom of the bolt, and the bottom surface of the limit seat 3 is in contact with the steel pedal. In order to prevent tripping when walking on the steel pedal, the top surface of the limit seat 3 is higher than the top surface of the bolt and the circumference of the limit seat 3 is an arc.

[0025] The above is only a description of the structure. The method of use is as follows: Figure 3 and Figure 4 As shown, S1, it is necessary to determine the control of the distance between two adjacent steel pedals, and adjust the distance between the two limit slots 4 according to the distance, so that the distance between the limit slots 4 matches the distance between the two adjacent steel pedals; S2, put the device under the steel pedal along the gap of the steel pedal (the positioning slot 1 is parallel to the gap of the steel pedal), so that the bottom edges of the two steel pedals are placed in the limit slot 4; S3, screw the stud 2, so that the stud 2 tightens the limit slot 4. If the length of the steel pedal is long, it can be spaced according to the above steps to prevent multiple connectors from being connected and controlled. For the above installation process, it is convenient and simple, and the distance between the steel pedals can be limited on the top layer of the steel pedal. In order to further improve the locking effect of the device on the steel pedal, it is further improved: after the width of the limit slot 4 is widened, a limit bolt 6 is provided on the outside of the limit slot 4, and the steel pedal bottom plate 7 is limited for the second time by screwing the limit bolt 6, so that the limiting effect of the device is better and more perfect.

[0026] In summary, the device is used to limit the gap between the two steel pedals and keep the steel pedals at a specific distance to prevent lateral movement between the steel pedals, thereby improving the stability of the steel pedals during installation.
