Description

Sliding form integrated lifting concrete curing device and curing method

technical field

The invention relates to the field of building construction, in particular to a sliding form integrated lifting concrete curing device and curing method.

Background technique

Concrete curing has always been a very important link in construction and a key process to ensure the strength of concrete. At present, there are various methods such as repeated watering curing method, brushing curing solution curing method, and straw mat plastic sheet curing method for concrete curing programs. The more commonly used ones are the curing method of brushing curing liquid and the curing method of bedding straw mats and plastic sheets. These two curing methods are more environmentally friendly and energy-saving, and at the same time have a good effect of curing and improving the strength of concrete, and are widely used in actual construction on site. But as the engineering structure features more and more responsible, diverse forms change. In the construction of tall cylindrical structures such as granaries, concrete maintenance is more difficult. At the initial stage, we tried to use curing liquid for maintenance. The specific operation is shown in Figure 1. Under the sliding form operation platform 5, set The hook fixes the springboard 6, and the worker hangs the safety belt and squats on the springboard 6 to paint the curing agent. Due to the disadvantages of large operating height and narrow working surface in the concrete maintenance construction of structures such as granaries, it is difficult for workers to operate flexibly when applying concrete curing agent. The quality of the curing agent is poor, which directly affects the curing of the concrete, and there is a big safety hazard, and it requires a lot of labor, which is time-consuming and labor-intensive. We combine the traditional watering and covering maintenance methods, and carry out patent research and development in terms of energy saving, environmental protection, flexibility and high efficiency. Developed a sliding form integrated lifting concrete curing device and curing method.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

As shown in Figure 2-Figure 5, the sliding form integrated lifting concrete maintenance device includes a PPR pipe ring 2, a tee 3, a hose 7, a quilt 1, and an iron hook 4, and the iron hook 4 is fixed on the sliding form for operation. At the lower end of the platform 5, the iron hook 4 hooks the PPR pipe ring 2, the PPR pipe ring 2 is arranged around the structure, the quilt 1 is suspended on the PPR pipe ring 2, and several small holes 8 are arranged on the PPR pipe ring 2 along the circumference, The PPR pipe ring 2 is connected to the hose 7 through the tee 3, and the hose 7 is connected to the water source.

A concrete curing film is wrapped on the quilt 1 and the PPR pipe ring 2, and water holes are evenly distributed on the concrete curing film inside the quilt 1.

The small hole 8 is arranged at the lower end of the PPR pipe ring 2 .

The method for maintaining the concrete of a structure by using a sliding form integrated lifting type concrete maintenance device includes the following steps:

1) At the initial stage of concrete structure construction, the iron hook 4 is welded and fixed on the sliding formwork operation platform 5, the lower end of the iron hook 4 hooks the PPR pipe ring 2, one end of the quilt 1 wraps the PPR pipe ring 2, and the other end hangs down naturally;

2) Wrap the PPR pipe ring 2 and the quilt 1 as a whole with a concrete curing film; uniformly punch holes in the concrete curing film inside the quilt 1;

3) Send water to the PPR pipe ring 2 through the hose 7, the curing water penetrates into the quilt 1, and then seeps out to the concrete structure through the holes on the concrete curing film to maintain the concrete component;

4) With the rise of the structure, the sliding form operation platform 5 drives the PPR pipe ring 2 and the quilt 1 to automatically lift, and maintains the structure at different heights.

The invention is suitable for concrete maintenance work of structures such as granaries and water towers. The inspiration of the invention comes from the reform of safety and quality hidden dangers in traditional construction. The sliding form operating platform 5 is a lifting construction operating platform. The device of the present invention is assembled from commonly used materials in the field. The PPR pipe is selected, and the pipe diameter is adjusted according to the project section size and other factors. In the granary project, we choose DN32PPR pipe. Use special PPR pipe fittings to make ring connections according to the building cross-sectional size. On the lower end of the PPR pipe ring 2, evenly arranged small holes 8 are opened. Wrap the PPR pipe ring 2 with one end of the quilt 1, and let the other end hang down naturally. The concrete-specific curing film is used to wrap the PPR pipe ring 2 and the quilt 1 in a winding manner, and uniform small holes are opened on the side close to the concrete. The connecting end of the PPR pipe ring 2 is connected by a PPR pipe fitting tee 3, and the hose 7 is connected to the upper end of the tee 3. In the early stage of concrete structure construction, the iron hook 4 is welded and fixed on the lower end of the sliding form operating platform 5, and is lifted along with the lifting of the sliding form operating platform 5. The water point is connected through the hose 7, and the water is circulated in the PPR pipe diameter to penetrate evenly into the quilt 1, forming a long-term and stable moist covering. The most effective curing of concrete by the simplest and original way. Traditional watering and maintenance requires a lot of water and manual input. Since the device is integrally lifted together with the sliding form operating platform 5, it does not need to be disassembled manually, and only needs to be connected to the water point. At the same time, due to the use of concrete curing film, the loss of water is suppressed, that is, the best effect of concrete curing is achieved, and the waste and pollution caused by the water demand for watering and curing are greatly reduced. Since the amount of water penetrates into the concrete surface evenly, the height of the wet covering and curing can be controlled by the height of the quilt 1, and a small amount of excess water will flow along the concrete surface due to the adsorption of the concrete surface, forming a wet area of 4 to 5 meters. Daily maintenance is carried out through a 2-meter-high wet coverage area combined with a 4-5-meter-high wetted area of about 7 meters to provide better environmental conditions for the growth of concrete strength. Taking the granary project as an example, the height of each concrete pour is 200mm, and the poured concrete volume is about 3.675m ³ . During the lifting process of the sliding form operating platform 5, the height of the device is adjusted through the hook 4. When the poured concrete reaches a certain initial strength, it is just covered by the concrete maintenance device suspended under the sliding form operating platform 5 . With the lifting of the sliding form operation platform 5, the cycle process of pouring concrete → platform lifting → concrete curing device covering the concrete area → platform lifting → wet area maintenance → platform lifting → pouring concrete is realized.
