Abstract

The utility model belongs to a new type cable duct gutter plank plate for the architecture of power system and consisting of a base plate and a wrapping edge. The base plate consists of glass fibers (five layers), cold drawn steel rods and concretes. The wrapping edge and the base plate are integrated in the process of the casting of concretes. The utility model has the advantages that three to seven layers of glass fibers and cold drawn steel rods are increased in the levels of the base plate, reducing the width and weight of the plank plate. The base plate and the wrapping edge are integrated in the process of the casting of concretes, greatly increasing the carrying capacity of the plank, reducing the damage rate and decreasing the manufacturing cost.

Description

The novel cable Ditch cover board

The utility model belongs to electric power system cable trench cover plate for building, specifically is exactly that cold drawn silk steel bar composite glass fiber and cement concrete constitute the cable trench cover plate.

CN98250154.4 discloses a kind of Ditch cover board, it comprises the armored concrete substrate, the back side at described concrete substrate extends-II type reinforcement, this reinforcement is a framework of steel reinforcement, and form at skeleton top casting concrete, adopt bound edge to handle around the described substrate, the reinforcing bar in this bound edge and said skeleton, the substrate fuses.In addition, existing cable trench cover plate is the ordinary reinforced concrete cover plate, and all to adopt angle steel be main material to bound edge all around.Defective is that bearing capacity is low, and breakage rate height, lid weight are big, and the production of product, transportation, installation and use are safeguarded and brought inconvenience and increased cost.

The purpose of this utility model provides a kind of bearing capacity height, breakage rate is low and novel cable Ditch cover board cheaply.

The purpose of this utility model provides a kind of bearing capacity height, breakage rate is low and novel cable Ditch cover board cheaply, it is made up of substrate and bound edge, substrate is made of glass fibre, cold drawn silk steel bar and concrete, and said bound edge and substrate become one in the concrete casting process; The glass fibre of said substrate is the 3-7 layer; Said bound edge is glass steel or plastic-steel.

The advantage of the utility model contrast prior art is: because added 3-7 layer glass fibre and cold drawn silk steel bar in the aspect of substrate, thereby reduced the thickness (or perhaps weight) of this cover plate.In addition, substrate and bound edge become one in the concrete casting process, improved greatly this cover plate bearing capacity, reduced breakage rate.Through experiment, when the thickness of substrate was the 1/3-1/2 of existing cable Ditch cover board, weight saving was more than 50%, and can guarantee the normal use of the load of the heavy automobile of 15-20 ton.In addition, this cover plate reduces cost about 40%.

Below in conjunction with drawings and Examples the utility model is further specified;

Fig. 1 is to use the structural representation of a kind of novel cable Ditch cover board of the present utility model;

Fig. 2 is the A-A cutaway view of this cover plate shown in Figure 1;

Fig. 3 is the B-B cutaway view of this cover plate shown in Figure 1;

Fig. 4 is the structural representation of bound edge;

Fig. 5 is the structural representation that cold drawn silk steel bar, glass layer, the bound edge of the utility model substrate do not cast.

Referring to accompanying drawing, is this cover plate requirement of 1.1m * 0.5m size with wide 25mm * thick 3mm by design specification, refers to admittedly that with epoxy resin, polyamide (1: 1) and epoxy resin agent (T-31 type) standard recipe adds glass fibre 6 (6 layers) and makes bound edge (referring to Fig. 4 glass 1-1 and glass fibre 1-2).Add solder joint 8 by 5 three of vertical cold drawn silk steel bars (diameter 6) and horizontal cold drawn silk steel bar (diameter 12) 7 two and constitute sheet-metal layers (seeing accompanying drawing 1).Fig. 1 gives the lifting hole 2 that being convenient on the substrate 3 installed this cover plate.In the casting cycle of the concrete 4 of this cover plate, be added with 6 four layers of glass layers respectively.Carry out after the casting quietly stopping, the demoulding, immersion health, be cost cover plate finished product after protecting.

Claims

1, a kind of novel cable Ditch cover board, it is made up of substrate and bound edge, it is characterized in that said substrate is made of glass fibre, cold drawn silk steel bar and concrete, and said bound edge and substrate become one in the concrete casting process.

2, novel cable Ditch cover board according to claim 1, the glass fibre that it is characterized in that said substrate is the 3-7 layer.
