Abstract
The utility model discloses a screw, and belongs to a fastener. The screw is used for fixing railway rails on a concrete sleeper. The screw comprises a screw body, wherein a ring-shaped flange is arranged on the screw body; the upper part of the screw body is a thread section; the lower part of the screw body is a connection section; the screw body is in a hollow structure; and a plurality of pits are arranged on the outer peripheral wall of the connection section. The screw provided by the utility model can be used for satisfying the connection strength, and simultaneously effectively saving the materials.
Description
Technical field:
The utility model relates to a kind of fastening piece, specifically is a kind of being used for railway track to be fixed on the screw rod on the concrete sleeper.
Background technique:
As shown in Figure 2, the existing screw rod that railway track is fixed on the concrete sleeper generally comprises the body of rod 22, and the body of rod 22 is provided with collar flange 21, and the body of rod 22 tops are thread section 20, and the bottom is a linkage section 23, and linkage section 23 is provided with screw thread.Use this screw rod fixedly during railway track; In the anchor hole that at first anchoring of founding slurry penetration concrete sleeper is provided with; The hand-held subsequently body of rod makes linkage section 23 vertical insertions in the anchor holes, treat that the anchoring slurry solidifies after; With fastener (like spring washer, buckle, iron seat, the nut etc.) thread section 20 of packing into, finally rely on fastener that railway track is pressed abd fixed on the concrete sleeper.Though above-mentioned screw rod is by extensive employing, it in actual application because the body of rod adopts is solid construction, thereby can cause certain waste of material.
In addition, because the linkage section 23 in the anchor hole of packing into is provided with screw thread, therefore, after the anchoring slurry solidified, the body of rod was prone to screwed out.
The model utility content:
The technical problem that the utility model will solve is, provides a kind of when satisfying join strength, can effectively save the screw rod of material.
The technical solution of the utility model is, a kind of screw rod with following structure is provided: comprise the body of rod, the body of rod is provided with collar flange, and body of rod top is thread section, and the bottom is a linkage section, and wherein, the body of rod is a hollow-core construction.
The described screw rod of the utility model wherein, can be distributed with several pits on the linkage section periphery wall.
The described screw rod of the utility model, wherein, pit can have two groups, and every group all has two row, two row pit flush, two groups of pits evenly distribute along the linkage section periphery wall is staggered.
After adopting above structure, compared with prior art, the utility model screw rod has the following advantages:
1, the body of rod adopts hollow-core construction satisfying under the situation of join strength, thereby has saved material greatly;
2, to be provided with screw thread different with the existing technology linkage section, and the utility model screw rod is provided with a plurality of pits on the linkage section periphery wall, therefore, in the utility model screw rod linkage section is packed anchor hole into after, other people are difficult for the body of rod is screwed out in the anchoring slurry that solidifies.
Description of drawings:
Fig. 1 is the stereochemical structure profile schematic representation of the utility model screw rod;
Fig. 2 is the main TV structure schematic representation of existing technology screw rod.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model screw rod is done further explain:
As shown in Figure 1, in this embodiment, the utility model screw rod comprises the body of rod 5; The body of rod 5 is provided with collar flange 2, and the body of rod 5 tops are thread section 1, and the bottom is a linkage section 3; The body of rod 5 is a hollow-core construction, is distributed with several pits 4 on linkage section 3 periphery walls, and pit 4 has two groups; Every group all has two row, two row pits, 4 flush, and two groups of pits 4 evenly distribute along linkage section 3 periphery walls are staggered.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technological scheme of the utility model all should fall in the definite protection domain of the utility model claims.
