Description

Hollow tubular lattice web plate

The utility model relates to structural material, is a kind of hollow tubular lattice web plate that is suitable for making door, window or wood clapper.

Existing lattice web plate, its typical structure be the lattice net each crooked shaft of rib all in the form of sheets, a lot of crooked shaft of rib interlinks and constitutes the lattice net, and every adjacent shaft of rib junction links with a linking rib, is not the lattice hole of a geometric form between the every adjacent shaft of rib of Lian Jieing.Though the force intensity that is subjected to of this kind sheet shaft of rib is good than general strip shaft of rib, but lattice net lamellar body easy deformation in manufacture process, as drawing in the net expansion when being a lattice net, drawing in the net the as easy as rolling off a log lattice net sheet body deformability that makes herein of holding position, again because when carrying before heat treatment, its lamellar body is very easy to be wound and local deformation.Another kind is a hollow pipe-type lattice web plate, and its each shaft of rib is hollow circular-tube.Though it has had higher intensity than sheet lattice web plate, the section of the shaft of rib of this lattice web plate is 0 shape, and upper and lower surface is quite smooth, actual making when being used as foot treadle skidded easily, and the stability of itself is not enough, is subjected to force intensity also undesirable, holds powerful impact of daring not accept.

The purpose of this utility model is to provide a kind of improved hollow tubular lattice web plate, makes the force intensity that is subjected to that improves hollow shaft of rib, can bear bigger impact force and to be difficult for by artificial destruction; Another purpose is can reach firm and non-slip, indeformable purpose when it is used as wood clapper.

Realize the utility model of above-mentioned purpose, equally with prior art also include a lot of crooked shaft of rib, adjacent shaft of rib interlinks and constitutes the lattice net, and every adjacent shaft of rib junction links with a linking rib, is not the lattice hole of a geometric form between the every adjacent shaft of rib of Lian Jieing.The design's characteristics are, each shaft of rib inside is S-type hollow.Another characteristics are that the upper surface of each shaft of rib is the plane, are shaped on the recessed body flange that is ratchet-like on it, and the bottom surface is a smooth flat.

The utility model has the advantages that, because shaft of rib inside is S type hollow-core construction, make and have the curved surface that out of phase distributes in the shaft of rib, if the design of this curved surface is walked back and forth arch bridge design, then the upper and lower horizontal protuberance of the hollow S type of shaft of rib inside more can bear the stress that is transmitted by external force, therefore the utility model can bear bigger stress, has the preferable force intensity that is subjected to when shaft of rib is subjected to external impacts.Secondly,, make to the utlity model has better shelf-stability that it is anti-skidding effectively that the shaft of rib upper surface is the concavo-convex edge physical efficiency of ratchet-like because of the bottom surface of each shaft of rib is the plane.The utility model is particularly suitable for doing door, window and road sole and uses.

Below in conjunction with the accompanying drawing illustrated embodiment the utility model is described specifically.

Description of drawings:

Fig. 1 does not expand the partial perspective view that adds man-hour for the utility model;

Fig. 2 is a partial perspective view of the present utility model;

Fig. 3 is implemented on the sectional perspective schematic representation of ditch lid for the utility model;

Fig. 4 is the sectional view of the utility model along the cutting of Fig. 3 A-A line;

Fig. 5 is implemented on sectional schematic diagram on the level land for the utility model;

Fig. 6 does the floor map that door and window uses for the utility model.

Label list in the above accompanying drawing is shown: 10-lattice web plate, and the 12-shaft of rib, the 14-linking rib, 16-lattice hole, 17-is hollow, the horizontal protuberance of 177-, the recessed body flange of 18-, 19-bottom surface, 30-flat board, 32-perforation, 40-L type edge, 60-ground, 80-doorframe.

At first see also Fig. 2.See that by Fig. 2 the utility model is made of a lot of crooked shaft of rib 12, a lot of crooked shaft of rib 12 formation lattice web plates 10 connected to each other.The junction of every adjacent shaft of rib 12 links with a linking rib 14, and 12 formations one of the shaft of rib of junction are not geometric lattice hole 16.Seen that by figure the inside of each shaft of rib 12 is made S-type hollowly 17 in the utility model, the upper surface of shaft of rib 12 is the plane, is shaped on the recessed body flange 18 that is ratchet-like on it, and bottom surface 19 is a smooth flat.

Making of the present utility model is comparatively simple.At first be drawn into flat board 30 as shown in Figure 1.See that by Fig. 1 the flat board that is drawn into 30 is the whole linkage structure of vertical bar shaped shaft of rib 12 and linking rib 14, S-type hollow 17 in the inside of every shaft of rib 12, the protuberance 177 that has upper and lower lateral projection in this S type hollow 17; The upper surface and the bottom surface of each shaft of rib 12 are the plane, and are shaped on the recessed body flange 18 of ratchet-like on upper surface.Then, need to make place, lattice hole and cut one section linking rib 14 on this flat board 30, making becomes a rectangular perforation 32 herein, with expansion machinery it is expanded at last, then becomes the utility model as shown in Figure 2.

The utility model may be implemented in ditch lid or makes the little unsettled lid of area, as shown in Figure 3, Figure 4, and among the figure-L type edge 40 is embedded on the concrete W hollow surrounding in advance, and the utility model then is positioned on the L type edge 40.

Figure 5 shows that the utility model uses embodiment on the ground.When the utility model being implemented on the building site of mire or avoid on the ground that pin directly tramples, owing to the utlity model has the preferable force intensity that is subjected to, the recessed body flange 18 that more is shaft of rib 12 surfaces has the on-slip effect, therefore people's all unlikely slipping on it of walking, and be not out of shape because of walking for a long time; Moreover, the flat contact surface that the bottom surface 19 of the shaft of rib 12 of the utility model has broad length, make and have splendid stability when being implemented on ground 60, especially the shaft of rib 12 of present embodiment has certain altitude, therefore as shown in the figure, when water directly washes, can be fast rinse out sticking at walk on the web plate face and ground mud or foreign material, just very convenient in cleaning.

The utility model may be implemented in door and window, and as shown in Figure 6, frame 80 combinations the utility model and window or door can become antitheft door, window.
