Description

Technical Field

[0001] This invention relates to the field of steel cage casting technology, and more specifically, to a protective cover for ground steel cage casting and its installation method. Background Technology

[0002] When casting steel reinforcement cages on the ground, multiple steel reinforcement cages are usually erected on the ground at the same time, and then cast in sequence as needed.

[0003] However, because the pouring needs to be done sequentially, the other sections waiting are easily corroded by weather and rain, which can affect the pouring process. At the same time, during the pouring process, the impact and splashing of cement can cause some of it to adhere to the inner wall of the mold near the higher part and solidify first, resulting in uneven defects on the surface of the final concrete column. Summary of the Invention

[0004] The purpose of this invention is to provide a protective cover for ground steel reinforcement cage casting and its installation method, which solves the problems that steel reinforcement cages are easily corroded by weather and rainwater while waiting to be cast, and that during the casting process, some of them may solidify on the inner wall of the mold in advance, resulting in differences in the surface of the final concrete column.

[0024] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] The following is combined with Figures 1 to 4 The present invention will be described in detail below.

[0026] A protective cover for ground steel reinforcement cage casting and its installation method are disclosed. The protective cover includes a steel reinforcement cage 1, a protective cloth 2 covering the side wall of the steel reinforcement cage 1, a top cover 201 connected to the top of the protective cloth 2, a mold cylinder 4 connected around the protective cloth 2, and a sliding component connected to the side wall of the steel reinforcement cage 1, with one side of the sliding component attached to the protective cloth 2.

[0027] First, several steel cages 1 are erected on the ground. Then, protective cloth 2 is used to cover the side walls of the steel cages 1 to protect them from rainwater and other corrosive substances. Since several steel cages 1 are erected at the same time and then poured in sequence according to the construction needs, some steel cages 1 will be exposed to the outdoors for a long time, making them susceptible to corrosion and damage from weather and rainwater, which will affect the later pouring.

[0028] Furthermore, the protective cloth 2 is cylindrical and fits into the reinforcing cage 1. The protective cloth 2 is made of a material with good sealing properties. The top cover 201 is connected to the top of the protective cloth 2 by means of zippers and Velcro. The protective cloth 2 also includes an injection pipe 202 and a folded bottom 203. The injection pipe 202 is located on one side of the protective cloth 2, and the folded bottom 203 is located at the bottom of the protective cloth 2. The injection pipe 202 is connected to an external inert gas source such as argon or nitrogen. The folded bottom 203 is the bottom part of the protective cloth 2 folded and laid on the ground. The reinforcing cage 1 also includes a sealing stack 3, which is located around the reinforcing cage 1 and is located on top of the folded bottom 203.

[0029] Then, after the protective cloth 2 is installed, the protective cloth 2 is sealed by forming a folded bottom 203 at the bottom and then covering it with a sealing pile 3. Then, inert gas is injected through the gas injection pipe 202 to reduce the oxygen content so that the steel cage 1 will not oxidize during long-term waiting.

[0030] Then, when it is time to pour, open the top cover 201 and pour cement into the protective cloth 2. After pouring a certain amount, stop pouring and pull the protective cloth 2 to move it above the cement. Then, agitate it. After the initial setting is completed, pour in a certain amount of cement. Repeat this process to complete the pouring of the steel cage 1. This ensures that the cement does not directly adhere to the inner wall of the mold near the high point due to splashing and impact. This prevents the cement splashed to the high point from solidifying first due to time difference. As a result, after the cement is fully poured and formed, there will be some difference and gaps between the cement that has solidified first and the cement that has been fully poured, which will prevent the concrete from forming a whole and affect the integrity of the side wall of the concrete column later.

[0031] Furthermore, the sliding assembly includes a roller 101, which is a cylinder fitted onto the side wall of the steel reinforcement cage 2.

[0032] Finally, when the protective cloth 2 is pulled and lifted, it will come into contact with the roller 101. The rotation of the roller 101 will reduce the friction of the protective cloth 2 when it moves, thus preventing the protective cloth 2 from being damaged due to friction and pulling.

[0033] Furthermore, the steps are as follows;

[0034] The first step is to first erect the steel cage 1 on the ground, and then put the protective cloth 2 on the top of the steel cage 1 from top to bottom so that the protective cloth 2 can completely wrap and cover the steel cage 1.

[0035] The second step is to connect the top cover 201 to the top of the protective cloth 2 by zipper or Velcro, so as to seal the protective cloth 2. Then the bottom part of the protective cloth 2 will be folded into a folded bottom 203 and laid flat on the ground.

[0036] The third step is to seal the inside of the protective cloth 2 by piling construction debris or mud and sand on the top of the folded bottom 203 to form a sealed pile 3, thereby sealing and protecting the multiple steel cages 1 to prevent the steel cages 1 from being corroded by rainwater or other substances during the process of waiting for pouring after the construction is completed.

[0037] The fourth step is to connect an air injection pipe 202 to one side of the protective cloth 2 and then draw inert gas into the protective cloth 2 to reduce the oxygen content inside the protective cloth 2, so that the steel bars will not oxidize when the protective cloth 2 has completed the protection of the steel cage 1 for a long time.

[0038] Fifth step: When it is necessary to pour the steel cage 1 in the protective cloth 2, take out the sealing stack 3, flatten and fold the bottom 203, and then put the mold cylinder 4 on the outside of the protective cloth 2. This allows the mold cylinder 4 to be isolated by the protective cloth 2 so that it will not directly contact and rub against the steel cage 1 during the process of putting it on, causing damage and affecting the later outer wall formation of the concrete.

[0039] Step 6: After the mold cylinder 4 is installed, open the top cover 201 of the protective cloth 2 to allow cement to be poured in. After a certain amount of cement has been poured in, pull and lift the protective cloth 2 from the top to raise it above the poured cement. Wait for the concrete to initially set before pouring it in again. Repeat this process to complete the pouring. This will prevent the cement from splashing onto the inner wall of the mold cylinder 4 near the high point due to the impact of pouring.

[0040] In the sixth step, when the protective cloth 2 is pulled and lifted, a roller 101 is also installed in the steel bar 1 of the steel cage 1. By rotating the connected roller 101, the protective cloth 2 will be pulled or put on, and the roller 101 will be pressed against the protective cloth 2. The rolling of the roller 101 will reduce the friction of the protective cloth 2 when it is put on and lifted, and prevent it from being damaged due to friction.

[0041] The following is a detailed implementation process of this invention: First, several steel cages 1 are erected on the ground. Then, protective cloth 2 is used to cover the side walls of the steel cages 1 to protect them from rainwater and other corrosive agents. Because several steel cages 1 are erected simultaneously and then poured sequentially according to construction needs, some steel cages 1 will be exposed to the outdoors for extended periods, making them susceptible to corrosion and damage from weather and rainwater, affecting subsequent pouring. After the protective cloth 2 is installed, a folded bottom 203 is formed at the bottom, and then a sealing stack 3 is used to seal the protective cloth 2. Inert gas is then injected through an injection pipe 202 to reduce the oxygen content, preventing oxidation of the steel cages 1 during long periods of waiting. Finally, when pouring is required, the top cover 201 is opened. Then, cement is poured into the protective cloth 2. After a certain amount has been poured, the pouring is stopped, and the protective cloth 2 is pulled and lifted to a certain extent without being removed, so that the protective cloth 2 moves above the cement. Then, it is agitated. After the initial setting is completed, a certain amount of cement is poured in again. This process is repeated to complete the pouring of the reinforcing cage 1. This ensures that during the pouring of cement, the cement does not directly adhere to the inner wall of the mold near the high point due to splashing and impact. This avoids the cement splashed to the high point from solidifying first due to time difference. As reinforcing cages are usually poured in sections, it is easy for the cement attached to the high point of the mold to solidify first. This will create a certain difference and gap between the cement that has solidified first and the cement that has been fully poured, which will prevent it from forming a whole and affect the integrity of the side wall of the concrete column later.

[0042] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
