Description
Technical Field
The utility model belongs to the technical field of the architectural equipment and specifically relates to a double nail type embedding slot.
Background
In recent years, in order to relieve traffic pressure of each big city, the construction of a subway network of the city begins, and in the construction process of the subway, the embedded channel component of the subway tunnel is very commonly used, but the existing embedded channel component has some defects in the use process. Traditional embedded groove, the groove back all adopt the bolt nail of "single nail", only are applicable to the little support wall of traditional load usually. Along with the enlargement in city, the construction in big urban mass and gulf district, all further improve to underground pipe gallery's needs and requirement, the inside pipeline of pipe gallery will be more concentrated, and the load is also along with the increase, consequently, not only requires more to the bearing capacity of trailing arm, also requires corresponding matching to the bearing capacity of embedded groove, and traditional "single nail" embedded groove must upgrade the reinforcement, just can satisfy the demand of bigger bearing capacity. Therefore, it is necessary to design a dual nail type pre-buried groove.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the prior art, a double-nail type embedded groove is provided.
The utility model discloses a following scheme realizes:
a double-nail type embedded groove comprises a straight plate-shaped bottom plate, wherein a plurality of pairs of embedded nails arranged side by side are correspondingly arranged at one end of the bottom plate, and a sliding groove is correspondingly arranged at the other end of the bottom plate; the embedded nails form a straight line and are parallel to the extending direction of the bottom plate.
The embedded nail comprises a straight rod-shaped anchor rod, the tail end of the anchor rod is correspondingly provided with a connector, the connector is of a circular truncated cone-shaped structure, the upper bottom surface of the connector is correspondingly connected with the tail end of the anchor rod, and the diameter of the lower bottom surface of the connector is larger than that of the upper bottom surface.
The diameter of the last bottom surface of connector equals with the diameter of anchor, the diameter of the last bottom surface of connector is greater than the diameter of anchor.
The ratio of the diameter of the upper bottom surface of the connector to the diameter of the anchor rod is 1.5-3:1, and the ratio of the length of the anchor rod to the thickness of the sliding groove is 2-3: 1.
The sliding groove comprises a straight groove in a shape of a Chinese character kou, and a penetrating opening is formed in the straight groove.
The ratio of the width of the straight groove to the width of the bottom plate is 1.5-3: 1.
The base plate is correspondingly provided with three pairs of six embedded nails, and the three pairs of embedded nails are uniformly distributed on the base plate.
The utility model has the advantages that:
the utility model relates to a double nail type embedded groove adopts and widens bottom plate and double embedded nail, is showing the bearing capacity that has improved the embedded groove.

In the figure: the concrete anchor rod is characterized in that 1 is a bottom plate, 2 is an embedded nail, 21 anchor rods, 22 is a connector, 3 is a sliding groove, 31 is a straight groove, 32 is an opening, and 4 is concrete.
Detailed Description
The preferred embodiments of the present invention will be further described with reference to the accompanying drawings in which:
as shown in fig. 1 and 2, a double-nail type embedded groove comprises a straight plate-shaped bottom plate 1, wherein a plurality of pairs of embedded nails 2 arranged side by side are correspondingly arranged at one end of the bottom plate 1, and a sliding groove 3 is correspondingly arranged at the other end of the bottom plate 1; the embedded nails 2 are two to one, and a plurality of pairs of embedded nails 2 form a straight line and are parallel to the extending direction of the bottom plate 1. Compare with traditional single row pre-buried nail 2, this application adopts pre-buried nail 2 to be two a pair of, the joint strength of increase embedded groove and concrete that can be multiplied.
Pre-buried nail 2 includes straight rod-like stock 21 the end correspondence of stock 21 is equipped with connector 22, connector 22 is round platform shape structure, the last bottom surface of connector 22 corresponds with the end of stock 21 and is connected, the diameter of the lower bottom surface of connector 22 is greater than the diameter of last bottom surface.
The diameter of the upper bottom surface of the connector 22 is equal to that of the anchor rod 21, and the diameter of the upper bottom surface of the connector 22 is larger than that of the anchor rod 21. The ratio of the diameter of the upper bottom surface of the connecting head 22 to the diameter of the anchor rod 21 is 1.5-3:1, and the ratio of the length of the anchor rod 21 to the thickness of the sliding chute 3 is 2-3: 1. Compare with stock 21, the surface area of connector is showing the increase, can improve the power of being connected between pre-buried nail 2 and the concrete, and then promotes the embedded groove of this application and can stably fix on the concrete for a long time, provides a reliable supporting platform.
The chute 3 comprises a straight groove 31 shaped like a Chinese character kou, and a through opening 32 is formed in the straight groove 31. In specific implementation, various cables are accommodated in the straight groove 31, and the cables are accommodated in the straight groove 31 through the opening 32, in this embodiment, the width of the opening is smaller than that of the straight groove 31, so that the cables can be effectively prevented from falling off from the opening. The ratio of the width of the straight groove 31 to the width of the bottom plate 1 is 1.5-3: 1.
As shown in fig. 3 and 4, in this embodiment, three pairs of six embedded nails 2 are correspondingly arranged on the bottom plate 1, and the three pairs of embedded nails 2 are uniformly distributed on the bottom plate 1. The embedded nails 2 are correspondingly embedded in the concrete 4.
Although the invention has been shown and described in detail with respect to the preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
