Description

Technical Field

[0001] The invention relates to the technical field of concrete pouring, and in particular to a mold structure and a process thereof for a reinforced concrete cup-shaped foundation. Background Art

[0002] The column foundation of industrial plants in industrial buildings usually adopts reinforced concrete cup-shaped foundation. The concrete cup-shaped foundation is a hole that can be used to place steel columns or concrete columns in the foundation. The size of the hole should be larger than the cross-sectional size of the column. After the column is placed in the hole, fine stone concrete (one level higher than the foundation concrete strength) is poured around the column. The cup-shaped foundation has the following advantages: the cup-shaped foundation can increase the bearing capacity by increasing the bottom surface area, the structural design is not complicated, the construction process is simple, the construction is simple, the construction period is short, and the cost is low.

[0003] The cup-shaped foundation and the cup mouth are usually supported by steel formwork or bamboo glue formwork during construction, and demolding after pouring is a difficult point, because the depth of the cup mouth is about 1 meter, and the width is about (0.15 meters to 0.5 meters) × (0.15 meters to 0.5 meters). The operators cannot stand inside the cup mouth when performing demolding operations, but can only stand on the cup mouth and insert a crowbar from the top to perform demolding operations. The final result is that a lot of time is wasted and the steel formwork or bamboo glue formwork is damaged and cannot be used a second time. In addition, the force generated by the crowbar when prying the formwork with the help of the cup mouth wall during demolition will also scratch or even damage the concrete of the cup mouth wall, which not only affects the appearance but also easily leads to quality problems.

[0004] The preventive measures usually taken to solve the above problems are: 1. Apply release agent on the surface of steel formwork; 2. Use plastic foam instead of steel formwork or bamboo glue formwork.

[0005] The above preventive measures have major disadvantages: 1. Steel formwork has the function of being reused and the steel formwork supporting the cup mouth will be destroyed after one use. Therefore, in order to reduce costs, old formwork will be used. However, the surface of the old formwork is relatively rough after being used for a long time, which increases the friction surface. Even if a release agent is applied, it cannot achieve the desired effect; 2. As the size of the cup mouth increases, the plastic foam becomes soft and brittle, and eventually two problems will occur: (1) it will be squeezed, bent or offset during concrete pouring; (2) when demolding, the foam can only be crushed and taken out in batches and cannot be reused. At the same time, the foam adhered to the concrete cannot be cleaned and affects the quality of pouring. Summary of the invention

Figure 7 and Figure 8 As shown, after pouring is completed, the support rod 11 is first taken out, and then the handle 9 is pulled toward the closed space 2 to separate the formwork 1 from the concrete, so as to prevent the formwork 1 from being pried by a crowbar and damaging the concrete structure. At the same time, the plastic foam board 12 and the transparent tape can also facilitate the separation of the formwork 1 from the concrete.
