[0002] With the widespread use of reinforced concrete in building structures, the ability of reinforced concrete structures to resist external environmental erosion has attracted increasing attention. In particular, in saline-alkali land and marine environments, reinforced concrete structures are subject to sulfate corrosion, chloride corrosion, and carbonation corrosion. These corrosions cause the reinforcing steel to rust, leading to the destruction of the reinforced concrete structure. To investigate the process and mechanism of external harmful substances penetrating concrete and causing steel corrosion and rust expansion cracking in reinforced concrete components, researchers need to use reinforced concrete components as the research object.

[0048] In the embodiment of the utility model, the working principle of the adjustable reinforced concrete mold is as follows:
[0049] According to Figures 1-9 As shown in the figure, after splicing the left half-cylinder mold cavity unit and the right half-cylinder mold cavity unit into the pouring mold cavity, the expansion and contraction positions of the pin bodies of the upper and lower spring pins are adjusted to adapt and clamp the upper and lower parts of the middle reinforcing steel bars in the pouring mold cavity, at this time, the radial mounting block abuts against the upper end surface of the pouring mold cavity;
[0050] The gap between the reinforcing steel bottom and the lower through hole is used to pour sand / melted wax water into the inside of the base, so that the sand / solidified wax water fills the inside of the base and seals the gap between the reinforcing steel bottom and the lower through hole, avoiding the subsequent concrete flowing into the inside of the base to affect demolding;
[0051] After coating lubricating oil on the inner circumferential wall and the inner bottom surface of the external sleeve, the assembled pouring mold cavity (with reinforcing steel inside) is sleeved into the external sleeve, the lower circumferential part of the annular cover plate is sleeved on the outer circumferential top part of the external sleeve to ensure coaxiality, and at the same time, the radial mounting block abuts against the upper end surface of the external sleeve;
[0052] After adjusting and confirming the position of the reinforcing steel again, the pouring mold cavity is poured with concrete;
[0053] After the concrete solidifies, the annular cover plate is removed, the foot plate is stepped on with the foot, the pouring mold cavity is pulled out from the external sleeve by holding the pull ring with the hand, and finally the left half-cylinder mold cavity unit and the right half-cylinder mold cavity unit are separated to take out the reinforced concrete member.
[0054] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments with equivalent changes.
