Description

Technical Field

[0001] The invention relates to the technical field of building construction equipment, and in particular to an integral horizontal opening and closing formwork system. Background Art

[0002] The new industrial intelligent construction technology "air building machine" is an equipment platform and supporting construction technology independently developed by my country. The air building machine and construction technology use mechanical operation and intelligent control to realize the industrial intelligent construction of cast-in-place reinforced concrete for high-rise residential buildings. One of its obvious features is that the entire process is completed in the air in a centralized manner, layer by layer. The equipment platform simulates a mobile building factory, moves the factory to the construction site, and uses mechanical operation and intelligent control methods in conjunction with the existing commercial concrete supply chain and concrete high-altitude pumping technology to carry out cast-in-place construction technology for the simultaneous construction of the main structure and the integrated insulation facing panels above the ground layer by layer, using machines instead of manual labor to realize the overall cast-in-place construction of high-rise and super-high-rise reinforced concrete.

[0003] At present, the aerial building construction machine includes multiple standard sections, jacking mechanisms, formwork platforms and truss platforms. Specifically, multiple standard sections are stacked and fixed in an end-to-end form to form a standard section group. Driven by the jacking mechanism, the truss platform and the formwork platform can both move up or down along the standard section group.

[0004] The template system used in the existing building construction machine has the following problems during use:

[0005] 1. The corner mold linkage mechanism is a single-link mechanism. The template linkage mechanism is prone to shaking and swinging during the process of closing the template and pouring concrete, resulting in inaccurate template positioning and poor pouring quality.

[0006] 2. The template opening and closing method is that the template is suspended under the platform and the template is opened and closed vertically. This method is subject to the deflection caused by the initial platform installation and the influence of the floor pouring height. Therefore, when the template is closed, the vertical displacement running size is insufficient, resulting in the template directly hitting the floor during the closing process until the template is damaged.

[0007] 3. The formwork anti-leakage system adopts the method of adding angle aluminum to the bottom of the formwork. This method is affected by the flatness of the concrete floor. Therefore, after the formwork is completed, it is necessary to add mortar to achieve the effect. However, in the corners of the wall and column, the lower space is small, which makes the construction difficult and the plugging effect is poor. At the same time, this method cannot effectively solve the problem of side leakage.

[0008] 4. During the template positioning process, the template needs to be positioned manually according to the marking reference. These methods are subject to the influence of the marking reference and the experience of the formwork workers. Each layer needs to be measured after pouring, and the measurement results are applied to the marking reference of the next layer. Therefore, the entire building may be offset to the left and right. At the same time, this method involves positioning marking and template positioning, which requires a lot of manpower and has certain requirements on the skills of the formwork workers. The labor intensity of the workers is high and the formwork speed is slow. Summary of the invention

[0062] Furthermore, the third connecting rod 23 and the fourth connecting rod 24 are columnar structures, and the shapes and sizes of the two are the same.

[0063] Furthermore, the forward rotation of the motor 18 drives the transmission screw 20 to rotate clockwise, and the reverse rotation of the motor 18 drives the transmission screw 20 to rotate counterclockwise.

[0064] The movement of the opening and closing mechanism 17 during the mold closing process of the present invention is as follows:

[0065] S1, initial state: the top position of the driving screw 20 is fixed on the template hoisting system, and the bottom of the corner template 15 and the flat template 16 are in contact with the floor 51 or the ground;
