Referring to fig. 1 to 4, a guard rail 10 suitable for a SMW method pile includes a crown beam 11, H-section steel 12, a fixing base 13, a vertical rod 14 and a cross rod 15.

The H-shaped steel 12 is provided with a plurality of H-shaped steels 12, and the H-shaped steels 12 are arranged at intervals in parallel along the length direction of the crown beam 11. Specifically, in the present embodiment, the H-section steel 12 includes transverse plates 121 disposed transversely and longitudinal plates 122 disposed longitudinally, two transverse plates 121 are provided, one longitudinal plate 122 is provided, and the two transverse plates 121 and the one longitudinal plate 122 are spliced to form the H-section steel 12.

The fixed base 13 comprises a clamping piece 131 and a connecting rod 132, wherein the clamping piece 131 comprises a connecting plate 1311 extending longitudinally and two clamping plates 1312 arranged at opposite intervals at the lower end of the connecting plate 1311, clamping grooves 1313 for clamping the H-shaped steel 12 are formed between the two clamping plates 1312, and through holes 13121 corresponding to lifting openings 1221 of the H-shaped steel 12 are formed in the two clamping plates 1312. The connection plate 1311 is used for being connected with the vertical plate 122, and as the connection plate 1311 extends longitudinally, the contact surface with the vertical plate 122 can be increased to ensure the connection stability, the two clamping plates 1312 are arranged at two sides of the lower end of the connection plate 1311 at opposite intervals along the longitudinal direction, the two clamping plates 1312 can clamp the vertical plate 122 through the clamping grooves 1313, and the lifting opening 1221 refers to a connecting opening for connecting and lifting the H-shaped steel 12 after the foundation pit is completed. Further, the connecting rod 132 is used to pass through the hanging hole 1221 and the through hole 13121 to fix the clamping member 131 to the H-section steel 12. The fixing bases 13 are provided in plural, and the fixing bases 13 are in one-to-one correspondence with the H-section steel 12, specifically, the clamping pieces 131 of the fixing bases 13 are respectively clamped on the H-section steel 12.

A plurality of vertical rods 14, wherein the plurality of vertical rods 14 are connected to the connecting rods 132 of the plurality of fixed bases 13;

the cross bars 15 are provided with a plurality of cross bars 15, and the cross bars 15 are respectively fixed on the vertical bars 14 at intervals in parallel and are arranged at intervals along the height direction of the vertical bars 14. Specifically, in the present embodiment, the vertical bars 14 and the horizontal bars 15 are vertically staggered with each other to form a lattice-shaped guard rail.

It can be understood that the technical scheme of the utility model is to clamp the H-shaped steel 12 by the clamping member 131 to position the fixing base 13 in the horizontal direction, pass through the lifting opening 1221 and the through hole 13121 by the connecting member to position the fixing base 13 in the vertical direction, and simultaneously, form the guard rail on the fixing base 13 by mutually vertically and horizontally staggered the vertical rod 14 and the horizontal rod 15.

In an embodiment, the fixing connection manner between the connection plate 1311 and the two clamping plates 1312 is various, for example, it may be a bolt assembly connection, welding, bonding, etc., as long as the connection plate 1311 and the two clamping plates 1312 can be fixed together, for this purpose, the fixing connection manner between the connection plate 1311 and the two clamping plates 1312 is not particularly limited, and in this embodiment, the connection plate 1311 and the two clamping plates 1312 are fixed by welding. It is obvious that the clamping member 131 may also be an integrally formed structure, and the corresponding connection plate 1311 and the two clamping plates 1312 are actually one integral plate.

In one embodiment, the inner sides of both clamping plates 1312 are covered with an elastic buffer layer 13122. Here, we refer to the side of the two clamping plates 1312 that is close to each other as the inner side of the clamping plates 1312, so that when the guard rail 10 suitable for the SMW method pile receives a large horizontal force, energy consumption can be buffered, so as to improve the service life of the guard rail 10 suitable for the SMW method pile.

Further, a clip groove 1313 is formed between the two elastic buffer layers 13122, and the distance between the two elastic buffer layers 13122 is smaller than the thickness of the H-section steel 12. Specifically, in the present embodiment, the distance between the two elastic buffer layers 13122 is smaller than the thickness of the longitudinal plate 122. It is easy to understand that, since the elastic buffer layer 13122 has elasticity, when the vertical plate 122 is inserted into the two clamping plates 1312, the elastic buffer layer 13122 deforms and contracts under force, so that the vertical plate 122 is inserted, and after the vertical plate 122 is inserted into the two clamping plates 1312, the elastic buffer layer 13122 is pressed inward due to elasticity, so as to improve the connection stability of the two clamping plates 1312 and the vertical plate 122.

Further, the end of the elastic buffer layer 13122 away from the web 1311 tapers toward the clamping groove 1313. It will be readily appreciated that since the end of the two resilient cushioning layers 13122 remote from the web 1311 is the entrance to the longitudinal plate 122 for insertion into the two clamp plates 1312, this provides the advantage of facilitating entry of the longitudinal plate 122 into the clamp slot 1313.

Further, the inner sides of the two elastic buffer layers 13122 are roughened, where the side of the two elastic buffer layers 13122 close to each other is referred to as the inner side of the elastic buffer layer 13122, and the inner side of the elastic buffer layer 13122 is roughened to improve the static friction coefficient, so that the elastic buffer layer 13122 and the vertical plate 122 can be tightly matched, and the vertical plate 122 can be prevented from sliding relative to the elastic buffer layer 13122, so as to improve the connection stability of the two clamping plates 1312 and the vertical plate 122.

Alternatively, the inner side surface of the elastic buffer layer 13122 may be a rough surface with concave or convex strips, or the concave and convex strips may be alternately arranged to achieve a rough effect. Accordingly, the rough surface concave bars or convex bars may be straight lines or curved lines, and of course, in other embodiments, the inner side surface of the elastic buffer layer 13122 may be rectangular or triangular, which is not particularly limited.

Further, the elastic buffer layer 13122 is made of rubber. It is easy to understand that rubber is under the prerequisite that satisfies elasticity, compare in the spring, rubber can carve or produce concave strip or sand grip on the surface to form the roughness, simultaneously, rubber has good wearability, can satisfy job site's demand, and rubber cost is great in addition, can reduce the manufacturing cost and the later stage use cost of rail guard 10 that are applicable to SMW worker method stake.

In an embodiment, the fixing base 13 further includes a first nut 133 and a second nut 134, the surface of the connecting rod 132 is provided with threads, and the first nut 133 and the second nut 134 are respectively fixed to the outer sides of the two clamping plates 1312 through the connecting rod 132. Here, the outer side surface of the clamp plate 1312 means a surface of the two clamp plates 1312 away from each other. The benefit of setting up like this is that, when unable adjustment base 13 installs, can be for connecting rod 132 location to avoid connecting rod 132 to hoist and mount mouth 1221 and through-hole 13121 internal displacement, and then improve the stability that two grip blocks 1312 and vertical board 122 are connected, when unable adjustment base 13 dismantles, only need dismantle first nut 133 and second nut 134, extract unable adjustment base 13 from vertical board 122 can accomplish the dismantlement.

In one embodiment, the guard rail 10 suitable for use with SMW method piles further includes scaffolding fasteners 16. In this case, the scaffolding is used for the connection of the vertical rods 14 to the connecting rods 132 and the vertical rods 14 to the transverse rods 15. Further, the scaffold fastener 16 includes a fixing plate 161, a first cover plate 162 and a second cover plate 163, where the fixing plate 161 has a first concave surface 1611 and a second concave surface 1612 that are oppositely disposed, the first concave surface 1611 is concavely disposed inward and extends in a vertical direction, one end of the first cover plate 162 is rotationally connected to one side of the first concave surface 1611 through a rotation shaft, the other end of the first cover plate 162 is fixedly connected to the other side of the first concave surface 1611 through a bolt, the second concave surface 1612 is concavely disposed inward and extends in a transverse direction, one end of the second cover plate 163 is rotationally connected to one side of the second concave surface 1612 through a rotation shaft, and the other end of the second cover plate is fixedly connected to the other side of the second concave surface 1612 through a bolt. The advantage of this arrangement is that on the one hand, the vertical rods 14, the connecting rods 132 and the cross rods 15 of different rod diameters can be adapted, and on the other hand, the stability of the connection of the guard rail 10 suitable for the SMW method piles can be improved, because the fixing plates 161 and the first cover plates 162 are arranged in a surrounding manner so as to wrap the outer circumferences of the vertical rods 14, and the fixing plates 161 and the second cover plates 163 are arranged in a surrounding manner so as to wrap the outer circumferences of the cross rods 15 or the connecting rods 132.
