The utility model provides a pier shaft tye anti cracking device, includes the pier shaft, pier shaft surface depression forms the tye that is used for the drainage, the laminating of pier shaft surface sets up vertical reinforcing bar, vertical reinforcing bar is kept away from pier shaft one side rigid coupling has horizontal reinforcement, horizontal reinforcement is kept away from pier shaft one side rigid coupling has the fixed block that is used for connecting the anti cracking net.
Furthermore, the distance between the anti-cracking net and the concrete surface layer is 25-30 mm.
Furthermore, the anti-cracking nets are arranged at intervals, and the distance between every two adjacent anti-cracking nets is 35-50 mm.
Further, the anti-cracking net is a galvanized steel wire net.
Further, the diameter of the vertical reinforcing steel bars and the diameter of the horizontal reinforcing steel bars are 6mm.
Further, the fixed block is a short steel bar.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the utility model discloses in, the diameter of vertical reinforcing bar and horizontal reinforcement that sets up on pier shaft and tye surface is 6mm, can improve the thickness of concrete protection layer to promoted the elastic modulus of concrete, and added the fixed block on the horizontal reinforcement, and connect the crack control net on the fixed block, crack control net interval sets up, can effectual laminating tye, finally prevent pier shaft tye concrete fracture, avoid influencing the wholeness of concrete.
(2) In the utility model, the anti-cracking net is arranged at the running water tank in a laminating way, and the anti-cracking net is a galvanized steel wire net, so the material cost is low; in the construction process, only the anti-cracking net needs to be additionally arranged, the fixing block is made of short steel bars, and the fixing block can be obtained from the existing steel bar materials without increasing the cost; the anti-cracking nets are arranged at intervals, and the distance between every two anti-cracking nets is 35-50 mm, so that the material is saved, and the cost is reduced.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The specific embodiment is as follows:
as shown in fig. 1, a pier shaft tye crack control device, including pier shaft 1, the sunken tye 11 that forms of pier shaft 1 lateral wall, the laminating of pier shaft 1 surface sets up the vertical reinforcing bar 2 of suitable quantity, one side fixed connection that pier shaft 1 was kept away from to vertical reinforcing bar 2 has horizontal reinforcing bar 3, horizontal reinforcing bar 3 bending shape and pier shaft 1 and tye 11 looks adaptation, the diameter of vertical reinforcing bar 2 and horizontal reinforcing bar 3 is 6mm, reduce the thickness of protective layer, promote concrete elastic modulus, the support body is constituteed to vertical reinforcing bar 2 and horizontal reinforcing bar 3, a protective layer for supporting whole pier shaft 1 and tye 11.
Further, one side fixedly connected with fixed block 4 that pier shaft 1 was kept away from to horizontal reinforcement 3, 4 intervals of fixed block set up, and the preferred short reinforcement of fixed block 4, short reinforcement diameter is less, does not invade the thickness that occupies the protective layer, and the short reinforcement does not have the incremental cost. One side that pier shaft 1 was kept away from to fixed block 4 is connected with anti cracking net 5, and anti cracking net 5 is 25 ~ 30mm apart from concrete surface layer 6, and anti cracking net 5 is preferred galvanized steel wire net, and galvanized steel wire net's bearing capacity is higher, and deformability is better, easily construction to the anticorrosive rust-resistant ability reinforcing of steel wire after the galvanization, life increases, is difficult for being damaged by the concrete. The grids of the anti-cracking net 5 can be made of concrete, are small in diameter and high in plasticity, and can ensure that the anti-cracking net 5 is attached to the steel bars at the position of the flume 11; and the anti-cracking nets 5 are arranged at intervals, and the distance between every two anti-cracking nets 5 is 35-50 mm, so that the anti-cracking nets 5 can be better attached to the launders 11.
The operating principle of a pier body tye crack control device in this embodiment is: the reason why the cracks are generated at the flume 11 is that after the protective layer passes, the semicircular arc-shaped stress is concentrated, so the thickness of the protective layer can be improved by adopting a reinforcing mesh consisting of vertical reinforcing steel bars 2 and horizontal reinforcing steel bars 3 with the thickness of 6 mm; the steel bars at the launder 11 are dense, so that the operation difficulty of the steel bars is increased, the plasticity of the steel bars is poor, and the steel bars cannot be completely attached to the launder 11, so that the anti-cracking net 5 is made of a steel wire net with strong plasticity, and the cost of the galvanized steel wire net is low; the fixing block 4 is a short steel bar, the diameter of the short steel bar is small, the short steel bar does not occupy the thickness of the protective layer, the anti-cracking net 5 can be fixed, and the cost of the short steel bar is not increased; the anti-cracking nets 5 are laid at intervals, the anti-cracking nets 5 are reduced, the anti-cracking nets are attached to the launder 11 better, and finally the concrete at the launder 11 can be prevented from cracking, so that the integrity of the concrete is guaranteed, the cost is low, and materials are saved.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
