In addition, the terms "first", "second" and the like are only for descriptive purposes, and cannot be understood as indicating or implying relative importance.

[0020] The drawings of the present application are schematic drawings that assist in explaining the concept of the present application, and schematically represent the shape of each part and its mutual relationship. Please note that in order to clearly show the structure of each component of the embodiments of the present application, the drawings are not drawn according to the same scale. The same reference signs are used to represent the same parts.

[0021] The principles and features of the present application will be described below in conjunction with the drawings, and the examples are only used to explain the present application and are not used to limit the scope of the present application. The preferred embodiments of the present application will be described in detail below: Figures 1-3 , the preferred embodiments of the present application will be described in detail:

[0022] As shown in Figures 1-2 , the preferred embodiments of the present application will be described in detail below:

[0023] The specific structural form of the anchorage support 2 can be selected comprehensively based on the actual construction needs on site and the convenience of material sourcing, such as... Figure 3 As shown, in some preferred embodiments, the anchor support 2 includes a socket-type concealed compartment 201 as a slot. The socket-type concealed compartment 201 is formed by welding together a concealed compartment bottom plate 202, a concealed compartment top plate 203, and three concealed compartment side plates 204. Several anchor bars 206 are fixedly provided at the bottom end of the concealed compartment bottom plate 202. A notch 205 is provided on the concealed compartment top plate 203. The size of the notch 205 matches the size of the column body 101, and the opening end of the notch 205 faces the hatch side of the socket-type concealed compartment 201 where no concealed compartment side plates 204 are provided. For safety reasons, in order to avoid objects falling from the opening, the hatch of the socket-type concealed compartment 201 needs to be set on the side away from the opening. That is, no concealed compartment side plates 204 are provided on the facade position of the socket-type concealed compartment 201 on the side away from the opening.

[0024] In order to better bond the anchor support 2 with the concrete of the structural floor slab 3 and prevent the anchor support 2 from loosening, the anchor bar 206 should have no less than three bars, and usually four bars are preferred. Of course, this also needs to be considered in conjunction with the size of the opening. If the size of the opening is large, and the overall size of the bottom plate 202 of the anchor support 2 is large, the number of anchor bars 206 also needs to be increased according to the calculation results. In order to increase the bond strength between the anchor bar 206 and the concrete, the anchor bar 206 is preferably made of threaded steel or has a hook at its bottom end. In order to fully recycle and utilize the steel bar waste and reduce the amount of construction waste, the anchor bar 206 is preferably made of the threaded steel waste formed by cutting steel bars on site.

[0025] like Figure 2 As shown, to ensure construction safety and prevent protrusions from tripping construction workers, the top of the dark compartment side plate 204 is flush with the top surface of the dark compartment top plate 203. At the same time, to better and more conveniently achieve welding and fixing of the dark compartment bottom plate 202 and the dark compartment side plate 204, the bottom end of the dark compartment side plate 204 extends beyond the bottom surface of the dark compartment bottom plate 202 to form a cantilever flange. Of course, also for the purpose of fully recycling steel plate waste materials and reducing the amount of construction waste, the dark compartment bottom plate 202, dark compartment top plate 203 and dark compartment side plate 204 are all made of steel plate waste.

[0026] When the on-site construction is completed, the edge hole position has been treated by a special process, at this time, the guardrail column 1 needs to be removed, at the same time, in order to ensure the integrity and beauty of the surface of the structural floor 3, the exposed position of the anchoring support 2 needs to be treated accordingly, in order to reduce the processing difficulty, the top surface of the anchoring support 2 needs to be lower than the top surface of the structural floor 3 when it is supported, and it is appropriate to leave a thickness of the steel bar protective layer, of course, since the guardrail column 1 needs to slide horizontally, the position of the surrounding side of the anchoring support 2 also needs to be sunken in the pouring stage of the structural floor 3, so that the guardrail column 1 has sufficient installation and removal space, of course, after the use function is completed, the concrete surface of the sunken place is chipped, and the anchoring support 2 and the sunken area around it are plastered and filled.

[0027] The manufacturing steps of the anchoring support 2 are as follows:

[0028] Step one: collect the steel bar cut-offs without use value on the construction site, and further cut them into the same length suitable for the concrete pouring conditions on the construction site;

[0029] Step two: collect the waste steel plate materials on the construction site, and make the end socket part of the anchoring support 2 with the socket hidden cabin 201 by simple cutting and welding.

[0030] Step three: weld the four equal-length steel bars with the bottom four corner parts of the hidden cabin bottom plate 202 to complete the manufacturing of the anchoring support 2.

[0031] The construction process of the utility model is as follows:

[0032] Step one: place the manufactured anchoring support 2 at the appropriate position of the edge hole to be poured with concrete, and fix it firmly;

[0033] Step two: after the concrete pouring of the structural floor 3 is completed and has a strength that can be walked on, insert the base plate 102 of the upper guardrail column 1 into the socket hidden cabin 201 to fix it firmly;

[0034] Step three: after the completion of the construction of this part and the completion of the edge protection work, the base plate 102 of the upper guardrail column 1 can be pulled out from the socket hidden cabin 201 of the anchoring support 2.

[0035] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
