The road manhole cover is convenient to be adjusted in height, low in cost, stable in structure and adjustable in height.

The invention provides an I-shaped web plate for a blade, a mold and a manufacturing method. The I-shaped web plate for the blade comprises a main body, a first baffle edge and a second baffle edge, wherein the main body is in a long-striped plate shape; the width of the main body is gradually reduced in a length direction from the root part to the point part of the main body; and the first baffle edge and the second baffle edge are formed at the two sides of the main body in the width direction of the main body so as to form an I shape with the main body. The I-shaped web plate provided by the invention has the advantages that the force bearing is balanced and uniform; and no bonding dead corner with a casing exists, and the like.

The invention discloses a "well" shaped intersecting vehicle running track, which comprises a bearing surface for carrying the weight of the vehicle and a limiting surface for limiting the axial displacement of wheels. The bearing surface and the limiting surface are bilaterally symmetrical, and the section is in the shape of "convex". The invention solves the defects of the existing "I"-shaped track that the bearing surface cannot be continuous at the vertical and horizontal intersections, the vehicle is not running smoothly, and the limit surface and the wheel edge have high friction. The vehicle running track of the invention runs smoothly at the intersection, has small friction, and the force on the bearing surface is symmetrical and even.

The invention discloses a hexagonal space capturing rope net. The hexagonal space capturing rope net comprises six reinforcing ropes of equal length and six side line ropes of equal length, wherein ends of the six reinforcing ropes are co-knotted to form a central rope knot; the six reinforcing ribs are outwards radial by taking the central knot as a center point; the other ends of the adjacent reinforcing robes are connected through the side line ropes; the joint of each side line rope and each reinforcing robe is led out of a traction rope; more than one screen is arranged in an area formed by the reinforcing ropes and the side line ropes in a converting mode. The invention also correspondingly discloses a knotting method for hexagonal space capturing rope net. The knotting method comprises the following steps: fixing reinforcing robes, sewing the screen, and sewing the side line ropes. According to the rope net and the knotting method thereof disclosed by the invention, the storage state consistency requirements of the rope net can be met, and the inner uniformity after the ropes are stretched is guaranteed, so that the topological structure conversion requirements of the rope net from the storage state to the stretching state are effectively met, and the stretching performance of the rope net is improved.

Disclosed are a smart home centralized control box fixing apparatus and mounting method. The smart home centralized control box fixing apparatus comprises a fixed box, a centralized control box, a buckling cover, a fixed screw and a wire; a fixed groove is formed in the fixed box; a fixed base is arranged on the back part of the centralized control box; the fixed base is inserted into the fixed groove; inclined inserting blocks are uniformly distributed on the exterior of the fixed base; inclined inserting block grooves are uniformly distributed in the fixed box; the inclined inserting blocks are inserted into the corresponding inclined inserting block grooves; a toothed column is arranged in the middle part of the fixed base; outer teeth are uniformly distributed on the exterior of the toothed column; a toothed column groove is formed in the fixed box; toothed grooves are uniformly distributed in the toothed column groove; the toothed column is inserted in the toothed column groove; the toothed grooves are matched with the corresponding outer teeth; fixed lugs are symmetrically distributed on the two sides of the fixed box; fixed box through holes are symmetrically distributed in the fixed lugs; connecting lugs are symmetrically distributed on the two sides of the centralized control box; centralized control box inner through holes are symmetrically formed in the connecting lugs; the fixed screw is inserted into the centralized control box inner through holes, the fixed box through holes and a wall body in sequence; the fixed box is connected with the centralized control box; and the fixed box is connected with the wall body.

The invention belongs to the technical field of wall finish material and relates to a heat-preserving wall space finish material. The heat-preserving wall space finish material comprises a finish material body, hanging pieces and filling material, the hanging pieces are connected to the back face of the finish material body, and the filling material is directly formed on the back face of the finish material body and on the hanging pieces on the back face of the finish material body or the filling material is bonded to the back face of the finish material body and to the hanging pieces on the back face of the finish material body. The hanging pieces include a first hanging piece and a second hanging piece, wherein the first hanging piece is fixed on the back face of the finish material body through a hook and a back bolt, and the second hanging piece is fixed on the first hanging piece. The hook formed by a turnup is arranged outward at the lower end of a bending part, the upper end of the bending part stretches inward to form a horizontal part first, then the edge of the upper end of the bending part is turned upward by a right angle to form a vertical connecting part with the wall, a mounting hole is formed in the upper middle part of the bending part, and finally the first hanging piece is formed. The horizontal part of the first hanging piece is located at the upper end of the filling material, the middle and the inner side of the second hanging piece are fixed on the first hanging piece in an attached mode, and a right-angle turnup is arranged at the outer end of the second hanging piece. The heat-preserving wall space finish material has the advantages of being good in heat preservation and firm in installation, saving steel and stone, and being suitable for serving as the finish material of indoor and outdoor walls.
