Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a hook-type steel ladder used for a scaffold. Background Art

[0002] With the continuous development of the construction industry and the continuous advancement of construction technology, the application scope and market size of the disc-type scaffolding, as a new type of scaffolding system for construction, are constantly expanding. During the construction process, the steel ladder plays a vital role in the erection of scaffolding and the construction of construction projects. As a vertical transportation facility, it can facilitate operators to shuttle back and forth between the upper and lower disc-type scaffolding. During the use of the disc-type scaffolding, the steel ladder is usually directly hung on the horizontal rod of the scaffolding. Due to the large size of the conventional steel ladder, it is easily constrained by the site conditions when in use. It is difficult for workers to operate during installation, and the installation efficiency is low; due to the large mass of the hanging ladder, it is not easy to move during installation and disassembly, which seriously affects the construction progress; for construction sites with smaller scene areas, due to the large overall footprint of the steel ladder, it is more troublesome to enter the site, which will affect the construction progress on the site. Summary of the invention

[0003] Therefore, the present invention aims to solve the problems of low installation efficiency and easy influence on construction progress in small construction sites of steel ladders used for scaffolding in the prior art, thereby providing a hook-type steel ladder for scaffolding.

[0004] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0005] A hook-type steel ladder for a scaffold comprises two ladder beams and a plurality of pedals detachably mounted between the two ladder beams, wherein the pedals are detachably mounted on the ladder beams via connectors; hooks are provided on both ends of the two ladder beams, and the hooks are suitable for mounting the steel ladder on the scaffold.

[0006] Furthermore, fixing parts are provided at both ends of the pedal, the fixing parts are installed on the ladder beam, and the pedal is detachably connected to the fixing parts.

[0007] Furthermore, the fixing member is an L-shaped angle steel, one side of which is suitable for being fixedly connected to the ladder beam, and the other side of which extends toward another ladder beam, and the other side of which is suitable for placing the pedal.

[0008] Furthermore, an L-shaped hole is provided on one side of the L-shaped angle steel connected to the ladder beam, and the connecting pieces are provided at both ends of the pedal. The diameter of one end of the connecting piece close to the pedal is adapted to the width of the L-shaped hole, and the diameter of the other end of the connecting piece is larger than the width of the L-shaped hole.

[0009] Furthermore, two L-shaped holes are formed on the L-shaped angle steel, and two connecting pieces are provided at both ends of the pedal, and the two connecting pieces at the same end are provided in a one-to-one correspondence with the two L-shaped holes on the same L-shaped angle steel.

[0010] Furthermore, the connecting member is a connecting bolt.

[0011] Furthermore, the ladder beam is square steel, and the fixing piece is fixed to the square steel by welding.

[0012] Furthermore, the hook is welded and fixed on the side wall of at least one end of the ladder beam.

[0013] Furthermore, hooks are provided at both ends of the ladder beam, and each of the hooks is provided with a buckling structure.

[0014] Furthermore, a telescopic sleeve is provided on at least one end of the ladder beam, and the fixing part and a pedal detachably connected to the fixing part are provided on the side wall of the telescopic sleeve; a plurality of spaced-apart sockets are provided on the ladder beam and the telescopic sleeve, and locking parts are provided on the corresponding sockets on the ladder beam and the telescopic sleeve, and the hook is welded and fixed to the telescopic sleeve.
