Description

Modular concrete spraying and curing system

Technical Field

The utility model relates to an equipment technical field that is used for the maintenance that contains the cement material, solidifies or hardens, especially relates to a modular concrete sprays maintenance system.

Background

Concrete is cured by means of the cement absorbing water to form a silicate/aluminosilicate containing water of crystallization that packs the aggregates together. Therefore, the concrete must ensure uninterrupted free water supply during the curing process, and once the free water is absorbed by the cement and cannot be timely supplemented, the concrete can crack due to shrinkage. It is therefore necessary to ensure that the concrete itself remains wet until it has completely cured after it has been poured. The process of making the concrete in a wet state is the water spraying curing of the concrete.

At present, most concrete members are sprayed and maintained manually by means of a spraying kettle or a water pipe held by a constructor. However, in some situations, the concrete curing cannot be completed by using the manual water spraying curing method for various reasons. For example, if the cast-in-place roof with a large area or the semi-cast-in-place roof is maintained by spraying water manually, the position where the water spraying maintenance is carried out finally has already been subjected to dry cracking after the maintenance is finished. For example, the cast-in-place building outer wall needs to be operated aloft when manual spraying maintenance is adopted, so that the loss is not paid. In these construction scenarios, constructors often choose to maintain concrete components using spray maintenance devices similar to sprinkler irrigation systems in arable land/gardens. In these spray maintenance devices, the spray headers need to be installed one by one and connected by pipes like a sprinkler irrigation system, and the whole process is troublesome.

The water amount required by concrete spraying and maintenance is far less than that of a sprinkling irrigation system, and the concrete component is only required to be sprayed with moisture. If the existing concrete spraying maintenance device can be lightened, the workload of installation can be obviously reduced.

Detailed Description

As shown in fig. 1-2, a modular concrete spraying maintenance system is formed by splicing a plurality of spraying units end to end, each spraying unit sequentially comprises a pipe joint 1, a hose section 2, a hard pipe section 3 and a tee joint 4 which are connected end to end from one end to the other end, a punching-free pipe clamp 6 is arranged on the hard pipe section 3, and a spraying head 5 is arranged on an outlet of the tee joint 4, which is vertical to a main flow channel; the spray header 5 sprays upwards to form a circular spray range.

The non-perforating pipe clamp 6 is a pipe clamp for small-diameter pipes and is stuck to a fixed foundation when in use. The non-perforating pipe clamp 6 needs to fix the spray header 5 and is arranged on the hard pipe section 3. However, if the flexible pipe sections are all hard pipes, the flexible pipe sections cannot adapt to concrete members with complex shapes, so that the flexible pipe sections 2 are arranged, the pipeline can be conveniently turned, and the flexible pipe sections 2 are higher in flexibility compared with elbows.

The spraying units are detachably fixed on the concrete piece to be maintained through the punching-free pipe clamp 6, and the spraying heads 5 are uniformly distributed on the concrete piece to be maintained. Note that the spray range of the spray headers 5 overlaps, and it is ensured that each position on the concrete element is covered without dead space. The length of the individual spray units should be less than the radius of the spray range of the spray header 5.

In this embodiment, the spraying units are spliced into a spiral pipeline structure on the concrete member to be maintained, so as to ensure that the spraying range of the spray header 5 covers the concrete member to be maintained.

The spraying maintenance system further comprises a pressure maintaining hose 7 used for avoiding too low water pressure of the rear section of the pipeline when the pipeline is too long, and in the spiral pipeline structure, the tail end of the pipeline is communicated with the water supply equipment through the pressure maintaining hose 7. If the concrete piece is very small, when the requirement can be met by a few spraying units, the pressure maintaining hose 7 can be omitted, and the tail end of the spraying unit is blocked after the spraying unit is combined.

The pipe joint 1 is an external thread joint, the tee joint 4 is an internal thread tee joint, and the internal thread tee joint is respectively connected with the spray header 5 and the pipe joint 1 on the adjacent spray unit in a threaded mode. Compared with a plug connection, the connection mode is less prone to water leakage or disconnection, and is suitable for the use scene with a plurality of pipeline segments in the application.

The hose section 2 is an armored hose. This prevents the hose section 2 from being blocked by excessive bending during use on site, or from being worn by various rough components or impurities on the construction site.

The non-perforating pipe clamp 6 is arranged on the hard pipe section 3 at a position close to the tee joint 4, so that the effective fixation of the spray header 5 is ensured.

The hard pipe section 3 is a PPR pipe.

The utility model discloses a method of use includes following step:

the method comprises the following steps: after the concrete member is initially set, the utility model is arranged on the concrete member, and then the inlet end of the utility model is communicated with the water outlet of the water supply equipment; if the pressure maintaining hose 7 is arranged, the tail end of the water supply device is also communicated with the water outlet of the water supply device through the pressure maintaining hose 7; the tail end is blocked without arranging the pressure maintaining hose 7;

step two: starting the water supply equipment and starting spraying maintenance. Here, the water supply device opens a water pump switch in case of a water pump and opens an outlet valve in case of a tap water pipe or a water tank.

The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
