Description

Prefabricated formwork for elevator shafts

technical field

The proposal relates to a formwork for making an elevator shaft, specifically an assembled formwork for an elevator shaft.

Background technique

When the elevator shaft is designed, the shaft wall is generally set as a shear wall, so as to facilitate the installation of the elevator track and improve the stability of the building. When pouring the elevator shaft, a cylindrical template will be set on the inside of the elevator shaft, so that the shaft of the elevator shaft will be formed after pouring. Since the elevator shaft runs through the building vertically and the size of the shaft is basically unchanged, the formwork inside the elevator shaft is generally made into a whole and installed by hoisting, and the bottom of the inner formwork is supported on the elevator shaft. On the wall of the well, mainly by drilling holes in the wall and inserting steel bars. In this way, a stand for people to stand needs to be built in the elevator shaft, thereby increasing the labor intensity of the workers. At the same time, the formwork inside the elevator shaft is made into a whole. When the formwork is hoisted, due to the friction between the formwork and the inner wall of the elevator shaft, the hoisting speed of the formwork is relatively slow, which affects work efficiency.

Utility model content

This solution intends to provide an assembled formwork for an elevator shaft to solve the problem in the prior art that the formwork is relatively slow to be hoisted due to the relatively large friction between the formwork and the inner wall of the elevator shaft.

The assembled template for the elevator shaft in this solution includes a template mechanism, an upper support mechanism and a lower support mechanism; the lower support mechanism includes a horizontally arranged support plate, and a group of inclined first support rods are arranged below the support plate , the lower end of the first support rod is hinged with a block, the lower part of the block is provided with a right-angle bayonet, the second support rod is hinged between one end of the first support rod and the support plate, the other end of the first support rod is connected to the A third support rod is hinged between the support plates; the upper support mechanism is located on the upper side of the support plate, the upper support mechanism includes a fixed frame, the bottom of the fixed frame is slidably connected with a vertical guide rod, and the lower end of the guide rod is connected to the support plate. Fixedly connected, the upper end of the guide rod is fixed with a limit block to prevent the separation of the fixing frame and the guide rod; the template mechanism includes four corner templates and flat templates, and the corner templates and flat templates are arranged at intervals in turn to form a rectangular cylinder. A connecting rod group is hinged between the angle formwork and the fixed frame, and the connecting rods in the connecting rod group are vertically distributed and parallel to each other. A push rod is arranged between the fixed frames, one end of the push rod is hinged with the flat template, and the other end of the push rod is threadedly connected with an adjusting sleeve, which is rotatably connected with the fixed frame.

Working principle: The flat formwork is in a state close to the fixed frame. At this time, the corner formwork is in a state close to the middle of the fixed frame under the action of the connecting rod group and the fixed frame. Use the hoisting equipment to connect with the upper support mechanism and lift the lower support mechanism and formwork mechanism, then put the lower support mechanism, upper support mechanism and formwork mechanism into the elevator shaft. When the lower supporting mechanism was positioned at the inboard of the elevator shaft, the block was rotated so that the block was stuck on the bottom of the elevator door opening of the elevator shaft. At this time, the first support rod is in an inclined state, one end of the first support rod is in contact with the block, and the other end is in contact with the inner wall of the elevator shaft. The support plate is in a horizontal state under the action of the second support rod and the third support rod. As the upper supporting mechanism is lowered gradually, the fixing frame of the upper supporting mechanism moves down along the guide rod, so that the fixing frame pushes the corner formwork to move away from the fixing frame through the connecting rod group, and finally makes the lower part of the corner formwork and the elevator The inner corners of the well are offset, and by rotating the adjusting sleeve, the adjusting sleeve pushes the flat formwork to move away from the fixed frame through the ejector rod, so that the flat formwork and the corner formwork are spliced together, so that the formwork mechanism forms a cylindrical formwork, avoiding concrete Go inside the elevator shaft.

Compared with the prior art, the advantages of this solution are: 1. By setting the block, the elevator door opening on the elevator shaft is used to support the block, so that the first support rod is supported obliquely inside the elevator shaft, which facilitates the second A support rod quickly performs support positioning. 2. By setting the fixing frame and the connecting rod group, the fixing frame drives the corner formwork to move laterally through the connecting rod group, so that when the formwork is installed, the corner formwork is offset against the inner corner of the elevator shaft under the gravity of the fixing frame, realizing The positioning of the corner formwork; when the formwork is disassembled, the fixing frame drives the corner formwork to move to the inner side of the elevator shaft through the connecting rod group, so that there is a gap between the corner formwork and the inner wall of the elevator shaft, which facilitates the removal of the formwork mechanism. 3. By setting the corner formwork and the flat formwork, the corner formwork and the flat formwork can be spliced and combined, so that it is convenient to adjust and reduce the outer contour size of the formwork mechanism when disassembling and installing the formwork, and increase the gap between the formwork mechanism and the inner wall of the elevator shaft. Large, which facilitates the rapid movement of the formwork mechanism in the elevator shaft.

Further, a number of lighting holes are provided on the support plate. By setting the lighting holes, after the formwork is installed, the lower side of the support plate is still in a relatively bright state, so that it is convenient for workers to work under the support plate without artificial lighting operation, which saves energy.

Further, the lower end of the third support rod is coaxially threaded with an adjustment rod, the lower end of the adjustment rod is ball-hinged with the first support rod, and the lower part of the adjustment rod has a regular hexagonal adjustment part. By setting the adjustment rod at the lower end of the third support rod, it is convenient to adjust the length of the third support rod, so as to adjust the horizontal state of the support plate and keep the support plate horizontal.

Further, the corner formwork is spliced with the flat formwork through tongue-and-groove. Splicing between the corner formwork and the flat formwork by tongue-and-groove can avoid joints at the joints of the angle formwork and the flat formwork, thereby reducing the phenomenon of concrete surface defects caused by the cement slurry flowing directly from the joint.

Further, a spacer is hinged to the upper end of the first support rod. By arranging the pads, the force-bearing area between the first support rod and the inner wall of the elevator shaft can be increased, thereby reducing the pressure on the inner wall of the elevator shaft, thereby reducing the damage caused by the first support rod to the inner wall of the elevator shaft.

Further, a limit bolt is provided between the fixing frame and the support plate. By setting the limit bolts, the fixed frame and the support plate are fixed to each other through the limit bolts, so that the fixed frame can generate a continuous support force for the diagonal formwork through the connecting rod group, so that the corner formwork can withstand greater concrete pressure. Enhance the stability of the formwork mechanism.
