Friends who engage in architecture all know what barbed wire construction is like, not to mention the barbed wire construction scheme we are going to talk about today. Before installing the barbed wire, we all need to monitor it on the spot and draw up the construction plan of the barbed wire, one for safety and the other for ensuring the life of the barbed wire. Professionals who plan to write barbed wire construction plans will put some necessary emphasis on the front. Let's take a look at it below.

Construction requirements

In the installation and construction of barbed wire, the posts of barbed wire should be fixed first. There are basically two fixing methods, embedded fixing and flange fixing.

Embedded fixation means digging a hole in the ground, putting the column in the hole, and backfilling with sand and lime. It's easy to say. Buried depth should be determined according to the height of barbed wire. Generally, the fence net is 1.8m-2m high and can be embedded in 30-35cm. As the height of the fence increases, the embedded size will also increase. Don't dig the pit too small, or it will be blown down by the wind. Generally, it is 400*400*400mm or 300 * 400 * 500 mm Fixing the upright post is also a technical activity, so it must be straightened, otherwise it will be difficult to hang the net, even if it is barely hung. When the sand and lime are solidified, it usually takes 1-2 days before hanging the net, otherwise the column will sink, resulting in different heights of the column top.

Generally, barbed wire fences are fixed to the concrete floor through flanges, and flange fixation is relatively simple. Fix the column chassis with expansion screws, and select the expansion screws according to the grid height. The higher the mesh, the thicker and longer the expansion screw, otherwise the fixation will be unstable and it will be skewed when hanging the mesh. After the column is fixed, the net can be hung directly to adjust the height.

method of erection

1、? Measuring and lofting; Stop construction lofting according to the 200mm (to ensure that the outer edge of the barbed wire fence column foundation does not cross the factory boundary) and the theoretical appearance characteristics, determine the column center line, and build a metal fence network according to the inclination and appearance of the rules. If there is a gap of 3m between columns at the corner of the boundary, the disconnection point or the intersection of roads, it can be mediated by two adjacent columns equally, but the gap should be less than 3m.

2、? Foundation pit construction; The standard of column foundation pit conforms to the construction specification, and the embedded foundation is added at the pit mouth and slope according to the specific situation to ensure firmness. Box formwork shall be used for site casting, and the concrete grade shall be no less than c20. The materials used for mixing concrete and the mixture ratio, mixing, pouring and curing of concrete shall comply with the provisions of relevant standards.

3、? Embedded columns; Stop burying columns in sections. Bury columns at both ends first, and then stay and bury the middle column. The axes of each column are on the same line, and there should be no mixed phenomenon. From the height point of view, the top of the column is smooth and curved outward, and there should be no unyielding height. Posts and hats should be strong and close to the tail.

4、? When the column is buried in the concrete foundation, temporary stay cables or supports are set and the column is fixed in a proper position until the concrete hardening stops. 14 During the curing period of concrete, it is forbidden to install or fasten any material on the column zipper or bracket, and all columns shall be linearly embedded according to the drawing.

5、? Guardrail nets meeting the requirements of standards and examples shall be firmly installed on the columns from the ends of the columns. All meshes should be tight and stable, and the installation height should meet the technological requirements. After installing the fence net, stop the final compaction of the column foundation.

6、? Special circumstances; The guardrail network is arranged along the stratum. In low and high areas, when the local vertical profile changes suddenly and can't resist the regular ground elevation, choose two columns to adjust the elevation or choose special-shaped mesh for gradual transition, and stop soil leveling when necessary to obtain a regular surface.

Whether it is the construction scheme of barbed wire fence or other construction-related work, we need to draw up an accurate and true construction scheme before construction. But every construction scheme is based on the above requirements, including construction requirements, construction methods and so on. Need what we know. Today's barbed wire fence construction scheme is no exception, but it can be modified according to the site area and functional type of work. The construction scheme of barbed wire fence ends here.
