Detailed Description
The following embodiments are only intended to illustrate the present invention in detail, and do not limit the scope of the present invention in any way.
Example 1:
a limb protection device is shown in figures 1-5 and comprises a tightening fixing mechanism (shown in figure 5) and a protection steel pipe 3, wherein the tightening fixing mechanism is respectively arranged on two side walls and comprises an L-shaped screw rod 2, a protection steel pipe 3, a screw cap 4 and U-shaped steel 5. The end part of one end of the L-shaped screw rod 2 is provided with a hook part 21 which is hooked on an existing reinforcing hole on a wall body and used for grasping the wall body, the end part of the other end of the L-shaped screw rod 2 is provided with threads, the end part penetrates through a bottom plate of the U-shaped steel 5 from an opening of the U-shaped steel 5, the L-shaped screw rod 2 penetrates out of a part of the U-shaped steel 5 to be in threaded connection with a nut 4, two ends of the protective steel pipe 3 are respectively arranged in grooves of the U-shaped steel 5 of the two clamping fixing mechanisms and are perpendicular to the L-shaped screw rod 2, and the protective steel pipe 3 is enabled to be tightly attached to the inner.
During the installation use, with L shape screw rod 2 card on facing limit entrance to a cave wall body 1, the opening of U shaped steel 5 is towards wall body 1 and hug closely wall body 1, all install at both sides wall body promptly and step up fixed establishment, protection steel pipe 3 passes and steps up the space that fixed establishment and wall body 1 enclose, with step up fixed establishment fixed facing limit protection steel pipe and form the protection system, U shaped steel passes through L shape bolt drawknot on concrete wall body, screw up the nut and make protection steel pipe, U shaped steel, concrete wall body form firm reliable protection. Because the intensity of screw rod and shaped steel is higher, dismantle the protection steel pipe at will when avoiding the workman to be under construction, and can retrieve completely after the pine unloads the nut, reach the mesh that can have enough to meet the need.
Example 2:
referring to fig. 6, the difference between the edge protection device and the embodiment 1 is that the screw is a linear screw 6, the screw penetrates through an existing reinforcing hole in a wall body, two ends of the screw are fixed by nuts, only a tightening and fixing mechanism is installed on the wall body 1, the other side of the wall body 1 is a corner wall 7, and a steel pipe is installed in a groove of U-shaped steel 5 and extends to the corner wall 7.
The present invention has been described in detail with reference to the accompanying drawings and examples; however, those skilled in the art will understand that various changes may be made in the above embodiments, or equivalent substitutions may be made in the related components, without departing from the inventive concept of the present invention, thereby forming a plurality of specific embodiments, which are common variations of the present invention and will not be described in detail herein.
