Description
Technical Field
The utility model belongs to the technical field of building construction equipment or device, concretely relates to built-in reinforcing bar pull rod is consolidated to concrete form.
Background
Based on the characteristics of high standard requirement on surface evenness of the existing hydraulic concrete high-speed flow area, high requirement on durability and appearance quality of permanent building concrete and the like, the traditional formwork reinforcement adopts an internal-pulling external-supporting mode, and the reinforcement method has the advantages of being reliable, convenient to operate and wide in application due to the fact that huge operators are skilled in the reinforcement mode. However, it also has the following disadvantages:
1. when the template is installed, the phenomenon of random opening of the template by arc welding is serious;
2. because the inner tie bars are firmly combined with the holes of the template, when the template is disassembled after the concrete lining is finished, the template is deformed due to improper disassembling method;
3. when the exposed internal pulling reinforcement bar head template is detached, the treatment is not timely, and the subsequent treatment cost is high;
4. the high-flow-rate water-passing lacing wire head is not properly treated, so that quality accidents are easily caused;
5. the influence of the surface lacing wire head of the concrete with the permanently exposed surface and the concrete with the water level change range to the appearance of the concrete is large;
6. the waste rate of anchor pulling round steel is high;
7. workers burn part of the reinforcing steel bar heads by electric welding to damage the inherent and appearance quality of the concrete surface;
8. the utilization frequency is only once, and the reuse cannot be realized.
Therefore, for the defects, the quality influence of the formed concrete surface reinforcing steel bar head on the concrete is analyzed according to the actual experience of the concrete surface reinforcing steel bar head treatment, and in order to effectively improve the appearance quality of the concrete, the concrete template reinforced built-in reinforcing steel bar pull rod treated by the concrete surface reinforcing steel bar head is provided.
Disclosure of Invention
The utility model aims to solve the technical problem that overcome above-mentioned prior art not enough, provide a reasonable in design, simple structure, reuse rate height, cost of manufacture low, avoid causing quality accident, the pleasing to the eye concrete form consolidates built-in bar brace of outward appearance.
The technical scheme for solving the technical problems is as follows: one end of the outer pull rod is movably arranged on the inner pull rod poured in the concrete, the other end of the outer pull rod is processed with a hexagonal prism surface, an outer screw is processed at a position on the outer pull rod adjacent to the hexagonal prism surface, a nut is arranged at the position of the outer screw of the outer pull rod, and a gasket is arranged at the position, close to the template, of the nut.
The utility model discloses an outer pull rod one end processing have with interior silk matched with internal thread on the interior pull rod, other end processing have 30 ~ 50 mm's hexagonal prism face, have 50 ~ 80mm outer silk with the adjacent processing of hexagonal prism face on the outer pull rod.
The utility model discloses an outer pull rod is made by the round steel hot rolling that the diameter is 18 ~ 20mm, and length is 300 ~ 400 mm.
Compared with the prior art, the utility model has the following advantages:
1. the utility model discloses on traditional "interior outer support that draws" basis, the purpose that the reinforcing bar head is not exposed on the concrete surface can be reachd to the built-in reinforcing bar pull rod of preparation.
2. The utility model discloses the pull rod cost of manufacture is low, reuse rate is high.
3. The utility model discloses need not artifical cutting and brush anti-rust paint, guarantee the pleasing to the eye requirement of concrete outward appearance, improved the efficiency of construction, effectively guarantee concrete appearance quality and inherent quality.
4. The quality accident caused by improper handling of the lacing wire head passing through the water surface at high flow speed is avoided, and the durability of the concrete is ensured.
The method can be popularized and applied to the field of concrete engineering template reinforcement of water conservancy, highways, railways, municipal administration and the like.
