Technical Field

The invention relates to the technical field of prefabricated concrete components, in particular to a vertical mold device for producing L-shaped and T-shaped prefabricated hollow shear wall panels.

Background

With the popularization of assembly type buildings, the precast hollow wall panels of the concrete shear wall structure are gradually and widely applied, but the existing assembly type buildings are not prefabricated by 100%, particularly high-rise buildings with the floor height of more than 10 floors, and the performance requirements on the aspects of seismic resistance, mechanical property and the like of the edge part of the concrete shear wall structure are higher due to the higher floor height, so that the edge part of the existing high-rise buildings is still finished by cast-in-place concrete.

The inventor of the patent application discloses a series of L-shaped and T-shaped concrete shear wall structure combined prefabricated edge member structures in CN201910078492.9, CN201920146443.X and CN 201920146441.0.

Then, the inventor of the present patent application further discloses a molding vertical mold device and a working method for producing L-shaped and T-shaped prefabricated edge members in CN110434980B, wherein the device comprises a surrounding template system and a core tube system; the enclosing template system comprises an angle-shaped outer template, a central template, a bottom template platform, an upper die gland, an end die carrier with a horizontal core pipe and a tooth post end die carrier; the angle-shaped outer template, the central template, the bottom template platform, the upper die gland, the end die carrier with the horizontal core pipe and the dental column end die carrier can enclose to form at least one die cavity with an L-shaped or T-shaped horizontal section; a hydraulic mechanism and a rack transmission mechanism are arranged on the outer side of the angle-shaped outer template; the core tube system comprises at least one side core tube, a corner core tube, a core tube supporting rod, a jacking platform and a jacking platform base; the lower extreme of side core pipe and the lower extreme of angle core pipe contact with the upper end of a core pipe bracing piece respectively, and the lower extreme of all core pipe bracing pieces is all installed on jacking platform, and jacking platform is located jacking platform base top. When the equipment works, the method comprises the following steps: (1) Placing a steel reinforcement cage, enclosing the angle-shaped outer template, the central template, the bottom template platform, the upper die gland, the end die frame with the horizontal core pipe and the tooth post end die frame, penetrating the horizontal core pipe firstly, and then penetrating the side core pipe and the angle core pipe; (2) Injecting concrete into the mold cavity, vibrating to compact, and curing; (3) After concrete curing and solidification molding, the jacking platform rises for a certain distance, and the core tube supporting rod jacks all the side core tubes and the corner core tubes together; a traction device on the tooth post end mould frame pulls the tooth post to move outwards for a certain distance; (4) continuing to maintain until the designed strength is reached; (5) Descending the jacking platform, and removing the side core tube and the corner core tube; and removing the angle-shaped outer template, the upper die gland, the end die carrier with the horizontal core pipe and the tooth post end die carrier.

However, the following defects still exist after the device is used:

(1) The whole equipment is as high as 6-7m, the side core tubes and the corner core tubes are lifted one by one when in use and then vertically placed from the upper part of the equipment, and after concrete is cured and formed, all the core tubes are lifted one by one and placed in a standby area.

On one hand, the lifting height is as high as 10m, and the danger is high; on the other hand, the core pipes are arranged one by one, taking the production of the wallboard in the CN110434980B shown in the figure 12 as an example, the equipment is produced once, the core pipes need to be hung and arranged for 24 times, the working efficiency is low, and the potential safety hazard of human bodies exists; the core tube is more subject to wear during the hoisting process.

In addition, in the concrete curing process, the core pipe supporting rods are required to jack up the core pipes, each core pipe is required to be provided with one core pipe supporting rod, and the whole equipment is complex in structure and high in manufacturing cost.

Therefore, how to reduce the height of the equipment, reduce the number of times of lifting and placing the core pipe, improve the production efficiency, reduce the cost and abrasion of the equipment and reduce the hidden danger of personal safety becomes one of the problems which need to be solved urgently.

(2) At present, the surfaces of core pipes equipped in concrete hollow prefabricated part production equipment are all smooth surfaces. For example, CN201510372560.4 discloses a preform core pulling tube and a method for manufacturing the preform, wherein the preform core pulling tube is composed of a plurality of independent sub core pulling tubes, and the sub core pulling tubes are made of steel tubes. The manufacturing method of the prefabricated member comprises the following steps: preparing a prefabricated member core-pulling pipe; (2) Placing the core-pulling tube of the prefabricated part into a prefabricated part manufacturing mold and positioning; (3) Pouring concrete into the prefabricated part manufacturing mould, and performing core pulling and demoulding after the concrete is cured and molded.

Although equipment structure is simple like this, and the core is pulled in being convenient for during the production prefab, in later stage construction, after the hollow prefab of concrete installation targets in place, need be at hollow hole position cast in situ concrete, after cast in situ concrete solidifies, need combine with the hollow prefab of concrete and form complete wall body, nevertheless because of the hollow hole inner wall is the plain noodles, so cast in situ concrete and the hollow prefab of concrete can't closely combine, lead to the anti-seismic performance of whole building not good.

Therefore, there is a need for an improved structure of the concrete hollow prefabricated member, so that the cast-in-place concrete is tightly combined with the concrete hollow prefabricated member in the later construction.
