Detailed Description

The drawings illustrate specific embodiments of the utility model. As shown in fig. 1 to 10, the fence for the construction site comprises a keel frame 1, namely a conventional framework, a plurality of cross beams and vertical beams are added in the middle, an iron plate is arranged on the front surface, at least three connecting plates 2 are fixedly arranged at the lower end of the back surface of the keel frame 1, and two connecting plates 2 are respectively positioned at two ends of the keel frame 1; all the connecting plates 2 can be heavier and serve as balancing weights, so that the stability of the utility model is improved; in addition, all connecting blocks are hinged with a bottom groove 3, the hinge point is positioned at the end part of the upper surface of each connecting plate 2, so that the bottom groove 3 can only be folded upwards, the back surface of the keel frame 1 above each connecting plate 2 is respectively provided with a vertical groove 4, and the vertical groove 4 and the bottom groove 3 are both T-shaped grooves; an I-shaped supporting rod 5, wherein two ends of the supporting rod 5 are respectively positioned in the vertical groove 4 and the bottom groove 3 and can rotate, and two ends of the supporting rod 5 are preferably cylindrical and are convenient for smooth rotation.

A baffle 9 is installed in all the bottom slots 3 to limit the position of the lower end of the support bar 5.

In the two bottom grooves 3 at the two ends, one bottom groove 3 extends outwards to form a protruding part 10, and the protruding part 10 is positioned outside the forming track of the lower end of the supporting rod 5; the same position of the other bottom groove 3 is provided with a concave part 11 inwards, a spring clamp 111 is arranged on the concave part 11, the shaft of the spring clamp 111 is positioned at the bottom of the concave part 11, the end parts of two clamping plates of the spring clamp 111 are provided with bending hooks 112 which are folded inwards, and the corresponding concave groove 101 is arranged on the convex part 10.

In addition, a plurality of plates 6 are arranged, the plates 6 can span two bottom grooves 3, through holes 7 are formed in two ends of the plates 6, and the through holes 7 are matched with steel bars 8.

The middle bottom groove 3 can also be matched with a plurality of templates 6, holes 7 are formed in the templates 6, steel bars 8 are matched, the templates 6 can only span one bottom groove 3, or the templates 6 which can span two bottom grooves 3 can also be matched, that is, the utility model can be matched with the same plurality of templates 6.

The use process is as follows:

in the folded state, the utility model is transported to a construction site, the keel frame 1 is erected, the bottom groove 3 is put down, the upper end of the supporting rod 5 at the middle part slides downwards in the vertical groove 4, the lower end of the supporting rod 5 slides in the bottom groove 3 until sliding to the baffle 9, the bottom groove 3 of the other utility model is laid down after being fixed by a steel chisel and a few plates 6, the adjacent two bottom grooves 3 are close together, the convex part 10 of one bottom groove 3 is inserted into the concave part 11 of the other bottom groove 3, the two bottom grooves 3 are clamped by the spring clamp 111, then the few plates 6 are spanned on the two bottom grooves 3 and are close to the lower end of the supporting rod 5, the baffle 9 or the concave part 11 and the few plates 6 limit the lower end of the supporting rod 5 together, the few plates 6 are also installed on the middle bottom groove 3, and then the steel chisel 8 is used for fixing, and the connection is carried out in this way, and a fence of a connecting piece is formed.

When the steel bar is disassembled, firstly, the steel bar 8 is pulled out, then the spring clamp 111 is pinched, the convex part 10 is withdrawn, the two utility models are separated, then the supporting bar 5 is lifted up, and the supporting bar 5 drives the bottom groove 3 to lift up and fold.
