Description

Production mould of concrete tower ring piece

Technical Field

The application relates to the technical field of dies, in particular to a production die for a concrete tower ring piece.

Background

Fig. 1 discloses a schematic diagram of a fan tower 1. As shown in fig. 1, a fan tower 1 generally adopts a concrete tower ring (hereinafter referred to as ring) 10 as a tower body, and is generally formed by two or four ring 10 on a whole ring, mainly in a reinforced concrete structure. When the ring sheet 10 is prefabricated in a workshop, the reinforcement cage of the ring sheet 10 is placed into a special mould, after concrete is poured, the mould is used for assisting in shaping the ring sheet 10, so that the external dimension and local characteristics (such as a positioning hole, a threaded hole, a boss and the like) of the ring sheet 10 meet the design requirements.

FIG. 2 discloses a schematic view of a piece of concrete tower ring 10 shown in FIG. 1. As shown in fig. 2, the ring segment 10 has two first planes (i.e., vertical planes 11 on the left and right sides as viewed in fig. 2), two second planes (i.e., horizontal planes 12 on the upper and lower sides as viewed in fig. 2), an inner arc surface 13, and an outer arc surface 14. The vertical surface 11 is used for being butted with the vertical surfaces of other ring pieces to form a whole ring, and the horizontal surface 12 is used for being butted with other whole rings to form the whole concrete tower.

The existing concrete tower ring 10 is usually prefabricated by a vertical mold, namely, a lower horizontal surface 12 of the ring 10 is used as a reference surface, an upper horizontal surface 12 is used as a grouting opening, and after the ring 10 is formed, the whole ring 10 is in a vertical standing state. However, the vertical die is limited by the space of the vertical die, the annular sheet reinforcement cage is difficult to put into the die and is easy to collide with the die, and the reinforcement cage is deformed; moreover, after the ring piece 10 is formed, the mold is opened, when the ring piece 10 is taken out, the difficulty of taking out operation is high, the operation is limited by the space of the vertical mold, the ring piece 10 is easy to collide with the mold in the taking out process, and the ring piece 10 is damaged secondarily.

In addition, the water collecting surface of the ring 10 is an upper horizontal surface using a vertical mold, and usually, the water collecting surface needs to be completed by a manual operation. However, the upper horizontal surface 12 of the ring 10 is a mounting surface, needs to be in butt joint with other ring, has control requirements of levelness and flatness, and is difficult to achieve precision by manual water collection. Moreover, in the process of forming the ring piece 10 by using the vertical mold, the ring piece 10 is in a vertical state, the lower horizontal surface 12 of the ring piece 10 is in contact with the mold, the contact area between the ring piece 10 and the mold is small, so that the stress on the mold is large, and the service life of the mold is influenced.

In addition, the vertical die is used, and because the whole vertical die is higher, the gravity center position is also higher, and the die table with larger volume and higher strength is needed to support the whole die, so that the die is prevented from tipping and toppling over, and the die cost is high.

Accordingly, in view of the problems associated with using vertical molds, there are also solutions that use horizontal molds to prefabricated the concrete tower ring 10. For example, there is a horizontal die in which a bottom die and side dies are fixed to a die table, the side dies are located at both side portions of the bottom die, and end dies are provided at both end portions of the bottom die. The bottom die is provided with a limiting upright post, and the top die is hinged in the limiting upright post of the bottom die so that the top die can rotate for a certain angle relative to the bottom die, thereby opening or closing the top die. The end mould is additionally provided with an air cylinder, so that the end mould can be automatically opened under the action of the air cylinder.

However, in this horizontal mold, since the connection device is designed between the top mold and the bottom mold, the mold opening operation can be performed without disassembling the top mold, but the top mold has a complicated structural design. Moreover, the top die is affected by the limit of the limit upright post on the bottom die and can only be opened to a vertical state, so that the operation space of the die is greatly reduced, the ring steel reinforcement cage can be easily knocked with the die when being put in, the steel reinforcement cage is deformed and damaged, the die is damaged, the ring is easily knocked with the die when being demolded, the ring is deformed or damaged, and the die is damaged; when the die is opened, the top die is in a vertical state, and the top die has a downward tilting trend due to the influence of the gravity center, so that the safety risk is increased.

In addition, the end mould opening and closing are completed by pushing the air cylinder, so that the manual operation is reduced, but the air cylinder is used, the prefabricated workshop is required to be supported by an air source, and the workshop construction cost is increased. Moreover, the cylinder is a precise component, so that the manufacturing cost is high, and the maintenance and replacement cost is high.
