Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to a table form for intelligent construction of a platform awning. Background Technique

[0002] Fair-faced concrete platforms are used in more and more high-speed railway stations because of their high-end, grand, thick and elegant characteristics; the awning is a cantilever concrete structure, usually in the form of single-column or double-column. The traditional construction method is to first pour the structural columns and then pour the beam and slab, and the support adopts full hall support, and the formwork mostly adopts the structural form of wooden keel + wooden formwork.

[0003] The following problems exist in the above construction technical scheme for the platform awning: (1) The disk buckle frame, formwork and keel are all disposable and have no turnover; (2) The main keel is composed of three arc-shaped slats fixed together by nails, all of which are cut and made from new formwork, resulting in a large waste; (3) The stiffness of the wooden keel is insufficient, and there are problems such as offset and mortar leakage at the joints of some formworks; (4) When using steel formwork, there is no turnover, the input formwork cost is high, and the self-weight of the formwork is large. A large amount of labor is required for installation and disassembly, and there is a certain danger. This technical scheme proposes a table form for intelligent construction of a platform awning for the above problems. Content of the Utility Model

The table form is composed of a chassis assembly with moving wheels and telescopic floor supports, a frame mechanism installed on the chassis assembly and composed of a lifting cylinder and a support sleeve limiting rod, a formwork system installed on a formwork installation platform and supported by a truss system, and a suspension early demolition device for suspending and pulling the concrete pouring structure of the platform awning; the corresponding table form is divided into multiple construction sections based on the platform awning for sequential construction, and can move and adjust its position independently. After the construction of one section is completed, a rain awning suspension early demolition device is installed above the awning structure to suspend and reinforce the awning cantilever structure, lower the table form to disengage from the awning structure, adjust the position of the table form to avoid collision between the table form and the awning column structure during travel, and move the table form to the next construction section; and the formwork system is composed of large formworks and loose formworks supported by a truss system. Compared with the existing structure of wooden keel and wooden formwork, it can be reused efficiently and has high turnover.

Detailed implementation manners

[0061] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0062] In the description of the present invention, it should be understood that the terms "both ends", "bottom", "vertical", "lower part", "middle", "hinged", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0063] As Figures 7 - 8 shown, two existing platform awning structures are shown, namely the double-column structure and the single-column structure. The specific embodiment of the present technical solution mainly takes the single-column structure for detailed description. Of course, the content of the present technical solution can also be applied to the double-column structure, only the specific structure of the mold is slightly different, and it also belongs to the protection scope of the present technical solution;

[0064] This technical solution divides the entire platform canopy into multiple construction sections based on the table formwork structure. After a construction section is completed and the concrete strength reaches 75%, a canopy suspension early-removal mechanism is installed above the canopy structure. The canopy cantilever structure is suspended and reinforced. The table formwork is lowered to separate from the canopy structure, and its position is adjusted to prevent collision with the canopy column structure during operation. The table formwork is then moved to the next construction section. The canopy suspension early-removal mechanism can only be removed when the canopy structural strength reaches 100%. These steps are repeated until the entire platform canopy construction section is completed. Our method allows for effective formwork turnover, significantly reducing formwork usage. Since the formwork can be removed once the concrete strength reaches 75%, construction efficiency is greatly improved and the construction period is shortened.

[0065] See also Figures 1 - 6 As shown, the utility model is an intelligent construction table form for a platform canopy, comprising a chassis assembly 1, a frame mechanism 5 mounted on the chassis assembly 1, a steering mechanism 6 mounted on the front and rear ends of the chassis assembly 1, a template installation platform 2 mounted on the frame mechanism 5, a truss system 7 mounted on the template installation platform 2, a template system 3 mounted on the truss system 7, and a canopy suspension early dismantling device 4 for cantilevering and pulling the solidified platform canopy concrete casting structure 9;

[0067] The frame mechanism 5 includes a vertically arranged lifting cylinder 503, a vertically arranged supporting sleeve 501, and a limiting rod 502 sleeved in the supporting sleeve 501; the limiting rod 502 is lifted synchronously with the lifting cylinder 503. After lifting, the space between the two adjacent limiting rods 502 and the supporting sleeve 501 on the front and rear sides of the frame mechanism 5 is reinforced by a scissor fork support structure, and the space between the two adjacent limiting rods 502 and the supporting sleeve 501 on both sides of the frame mechanism 5 is reinforced by an oblique supporting structure; there are multiple lifting cylinders 503, and the cylinder height of the lifting cylinder 503 is the same as the height of each supporting sleeve 501, so that each limiting rod 502 can be lifted synchronously under the synchronous lifting action of the lifting cylinder of each lifting cylinder 503;

[0069] The specific steering action of the steering mechanism 6 is:

[0070] When the steering jacking cylinder 602 is in the jacking state, the moving wheels 103 and the telescopic floor supports 102 are lifted off the ground. At this time, the two sliders 603 are jointly moved to the left or right by the double-acting hydraulic cylinder 604, showing that one side is jacking and the other side is contracting, and the jacking and contracting strokes are the same. Since the steering jacking cylinder 602 is hinged to both the chassis assembly 1 and the slider 603, after moving a certain distance, the corresponding steering jacking cylinder 602 changes from an inclined state and then descends to a vertical state again, thus realizing a certain angle of steering movement of the corresponding table form as a whole;
