Description

A new type of protective railing

Technical Field

The present application relates to the technical field of beam erection site protection, and in particular to a novel protective railing.

Background Art

A beam in engineering construction refers to a horizontal beam used to support and carry the structure of a building. During construction, beams are usually made of reinforced concrete or steel. Their main function is to bear the weight of the floor and roof and transfer it to the supporting walls or columns.

At present, there is a lack of relatively safe protection measures for the existing construction engineering beam erection site operations. On-site project technicians use traditional wire rope protection nets to fence off the site. However, the use of traditional wire rope protection nets has the following inconveniences: due to the large span of the beam erection site construction, the wire rope protection net is inconvenient to transfer, and it needs to be rolled up, unrolled and erected, which has low installation efficiency. The wire rope protection net has low strength and low safety factor, and it is difficult to meet current needs.

In view of the problems existing in the above-mentioned prior art, a new type of protective railing is proposed to solve the above-mentioned problems.

The guide rod passes through the sliding holes and slides relative to the sliding holes.

Furthermore, the number of the guide rods and the sliding holes includes two, and the two guide rods are arranged up and down.

Furthermore, the connecting pin is a round rod, and the number of the slide grooves is several, and the several slide grooves are arranged obliquely on the connecting plate corresponding to the positions of the connecting pin, and at the same time, the clarity of adjacent slide grooves gradually increases in the direction close to the middle of the connecting plate.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Please refer to Figures 1-4. A new type of guardrail in this embodiment includes a guardrail frame and a bracket member distributed up and down. The bracket member is adjustable relative to the guardrail frame, wherein the bracket member is used to support the guardrail frame so that the guardrail as a whole has a certain height.

In this embodiment, the bracket member includes a support rod 4 and an extension frame 5 welded to the support rod 4. The extension frame 5 is an L-shaped frame, one end of which is welded to the support rod 4, so that the lower end of the support rod 4 can have two supporting points, and the stability of the support frame is improved by the vertical angle steel structure.

It should be noted that the railing frame includes an upper beam 1 and a lower beam 2 arranged vertically, and a number of reinforcing rods 3 are fixedly installed between the upper beam 1 and the lower beam 2. The reinforcing rods 3 are evenly distributed between the upper beam 1 and the lower beam 2, and the two ends of the reinforcing rods 3 are respectively welded to the upper beam 1 and the lower beam 2, so that the overall strength of the railing frame is improved.

It can be understood that the interior of the lower beam 2 is hollow, and the depth of the lower beam 2 is greater than the depth of the upper beam 1 , so that space can be reserved in the lower beam 2 .

The lower beam 2 in this embodiment is provided with a connecting mechanism for connecting the lower beam 2 and a traction mechanism for pulling the lower beam 2 to move. The connecting mechanism includes a guide rod 6 fixedly installed between the left and right inner walls of the lower beam 2. The lower end of the lower beam 2 is open. The support rod 4 slides in contact with the inner wall of one side of the lower beam 2. Sliding holes 7 are opened on the left and right sides of the support rod 4. The guide rod 6 passes through the sliding hole 7 and slides relative to the sliding hole 7.

In this embodiment, there are two guide rods 6 and two slide holes 7 , and the two guide rods 6 are arranged up and down, so that the rotation of the support rod 4 relative to the guide rod 6 is limited.

It should be noted that the connecting mechanism also includes a connecting plate 8 slidably installed in the lower beam 2, a sliding groove 9 is provided on the connecting plate 8, and a connecting pin 10 is fixedly installed on one side surface of the supporting rod 4 facing the connecting plate 8, and the connecting pin 10 is slidably connected to the sliding groove 9.

In this embodiment, the connecting pin 10 is a round rod, and the number of the slide grooves 9 is several. The several slide grooves 9 are arranged obliquely on the connecting plate 8 corresponding to the position of the connecting pin 10. At the same time, the clarity of adjacent slide grooves 9 gradually increases in the direction close to the middle of the connecting plate 8. The connecting pin 10 is guided by the obliquely arranged slide grooves 9, so that several support rods 4 can achieve equidistant and synchronous adjustment of traction.

In this embodiment, guide frames 11 are fixedly installed on the left and right inner walls of the lower beam 2, and the two ends of the connecting plate 8 are respectively slidably connected to the guide frames 11. The guide frames 11 can improve the sliding stability of the connecting plate 8 in the lower beam 2.

In this embodiment, the traction mechanism includes a cylindrical pile 12 fixedly mounted on the connecting plate 8, a threaded sleeve 13 installed in the cylindrical pile 12, and a threaded rod 14 threadedly connected to the threaded sleeve 13, wherein one end of the threaded rod 14 is rotatably connected to the inner top wall of the lower beam 2, and the threaded sleeve 13 passes through the cylindrical pile 12 in an upward and downward direction. By rotating the threaded rod 14, the cylindrical pile 12 can move up and down.

It should be noted that a hand wheel 15 is rotatably mounted on the outside of the lower beam 2 , and the hand wheel 15 is fixedly connected to the threaded rod 14 . The threaded rod 14 can be conveniently pulled to rotate by rotating the hand wheel 15 .

The working principle of the above embodiment is:

When installing the guardrail, the guardrail frame is transferred to the on-site erection position, and the staff manually rotates the handwheel 15, which drives the fixedly connected threaded rod 14 to rotate synchronously. The threaded rod 14 is threadedly engaged with the threaded sleeve 13 during rotation. At this time, the cylindrical pile 12 connected to the threaded sleeve 13 drives the fixedly connected connecting plate 8 to move vertically in the lower beam 2. The slide groove 9 on the connecting plate 8 slides relative to the connecting pin 10, so that the support rod 4 slides horizontally relative to the guide rod 6, that is, the spacing between several bracket members is adjusted, so that the bracket members are unfolded to facilitate supporting the guardrail frame. By fixing the bracket members, the guardrail can be quickly erected. At the same time, the guardrail has good strength through the reinforcing rod 3 arranged in an I-shaped structure.

It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
