Description
Technical Field
The utility model relates to an auxiliary forming field, concretely relates to template exposes reinforcing bar department and ends thick liquid device.
Background
With the continuous development and perfection of the construction of basic facilities such as railways, highways, house buildings and the like in China, the quality technical standard is continuously improved, and strict control must be carried out in the construction process to realize the quality target. Especially, on the premise of improving quality, in order to save cost and construction period, a plurality of railway and highway bridges in China adopt precast beams and other cast concrete construction processes, namely, one bridge consists of a plurality of precast beams. And the precast beams are integrated by adopting the forms of reserved exposed steel bars, prestress and the like, so that the exposed steel bars with enough length are reserved when the precast beams are produced.
During construction, steel bar reserved holes are formed in the templates in advance according to steel bar spacing and steel bar models required by design drawings, and steel bars penetrate out of the steel bar reserved holes to meet the requirement of reserved exposed steel bars during construction. In order to successfully remove the template after the concrete strength of the precast beam reaches, the diameter of the steel bar preformed hole is larger than that of the steel bar, so that certain gaps exist between the steel bar and the steel bar preformed hole, and the gaps can cause the concrete to have quality defects such as slurry leakage and cellular pitted surface.
The traditional construction method is to adopt sealing materials such as foaming agent to seal the hole gap, thus the purpose of preventing slurry leakage can be achieved, but the phenomena of irregular pits, local exposed aggregates and the like of a component are easy to occur due to inaccurate control during construction, the cost is increased due to later-stage repair, and the foaming agent is a material which can not be recycled, so that the environmental pollution is easy to cause. If a recyclable pulp stopping device is adopted, the above situations can be avoided. The company has invented a utility model with an authorized bulletin number of CN202344670, which uses a rubber plug sleeve to cover the steel bar, and compresses a plurality of rubber plugs simultaneously by a compressing frame to prevent the reserved holes of the steel bar from leaking slurry. However, in this way, the pressing frames with different sizes need to be designed according to the distance between the steel bar preformed holes, namely, the pressing frames need to be designed according to the requirements of design drawings at each time, and material waste is caused. And because the application of force of the compression frame is uneven, the end face of the rubber plug can not be tightly attached to the template, and the situations of slurry leakage and the like still occur at partial positions.
Therefore, in order to solve the above problems, a grout stopping device for exposed steel bars of a template is needed, which can be suitable for different design requirements and completely avoid grout leakage.
