Description

Technical Field

[0001] This utility model relates to the technical fields of cantilevered waterfront platforms for water conservancy projects, widening of the open side of traffic roads, and separation of pedestrians and vehicles on traffic roads. Background Technology

[0002] Currently, the width of cantilevered waterfront platforms or road widening on the open side of traffic roads is generally narrow, which greatly limits the use of the open space. Moreover, cantilevered platforms have high requirements for the supporting structure, and often require a lot of cost for structural reinforcement and foundation treatment. The calculation is mainly based on the corbel model. Therefore, there is an urgent need for a new type of widened cantilevered platform structure based on the lever principle. Utility Model Content

[0003] The purpose of this utility model is to provide a novel cantilever platform structure based on the lever principle, so as to solve the problems mentioned in the background art, such as high requirements for structure and foundation, large investment, and narrow splicing width of existing cantilever platforms.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel cantilever platform structure based on the lever principle includes a recessed hollow box structure and a rod-beam plate structure. The recessed hollow box structure serves as the basic support structure of the entire cantilever platform structure system. The rod-beam plate structure is fixedly connected to the top of the recessed hollow box structure. The rod-beam plate structure extends a certain length on both sides of the recessed hollow box structure to form a cantilever structure. A counterweight block is fixedly connected to the lower inner end of the rod-beam plate structure. The outer edge of the lower foundation of the recessed hollow box structure serves as the fulcrum of the entire cantilever platform structure. The outer side of the rod-beam plate structure extends a corbel structure as the support arm of the cantilever platform structure. The corbel structures are connected as a whole by corbel connecting beams to form a complete lever system.

[0006] Furthermore, a paving layer is laid on the upper part of the rod-beam structure.

[0007] The main force transmission process of this utility model is as follows: the outer edge of the lower foundation of the grooved empty box structure is used as the fulcrum. The self-weight of the cantilever platform and its upper load form a dynamic torque, and the self-weight of the counterweight block and its upper load form a resistance torque. Through the rod beam plate structure, a complete lever system is formed.

[0008] The beneficial effects of this utility model are:

[0009] This utility model can effectively widen open-air traffic roads, open-air cantilever leisure platforms, riverside flood control roads, and riverside cantilevered waterfront platforms. The widening width can be flexibly controlled by adjusting the length of the resistance arm and the size of the counterweight, greatly saving the volume and cost of the foundation support structure required for the cantilever platform. The interior of the empty box structure can also serve as a pedestrian passage or basement to form a convenient traffic system that separates people and vehicles. The upper cantilever platform can be used for road widening or leisure and entertainment areas. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-2This utility model discloses a novel cantilever platform structure based on the lever principle, comprising a recessed hollow box structure 1 as the basic support structure of the entire cantilever platform system. A rod-beam structure 4 is fixedly connected to the top of the recessed hollow box structure 1. The rod-beam structure 4 extends a certain length on both sides of the recessed hollow box structure 1 to form a counterweight structure and a cantilever structure. A counterweight block 6 is fixedly connected to the lower inner end of the rod-beam structure 4. The outer edge of the lower foundation of the recessed hollow box structure 1 serves as the fulcrum 2 of the entire cantilever platform structure. The self-weight of the cantilever platform and... The sum of the loads on its upper part forms a dynamic load G2, the center of gravity of which is the combined center of gravity of the dynamic load C2. The dynamic load G2 multiplied by the dynamic arm L2 forms a dynamic moment. The sum of the loads on the counterweight 6 and its upper part forms a resistance load G1, the center of gravity of which is the combined center of gravity of the resistance load C1. The resistance load G1 multiplied by the resistance arm L1 forms a resistance moment. The outer side of the beam-slab structure 4 extends a corbel structure 3 as a support arm of the cantilever platform structure. The corbel structure 3 is connected into a whole by the corbel connecting beam 5, forming a complete lever system. A pavement layer 7 is laid on the upper part of the beam-slab structure 4. In order to ensure the overturning stability of the widened cantilever platform structure, a safety factor of 2 is considered, thus requiring G1×L1≥2×G2×L2.

[0015] The working principle of this utility model is as follows:

[0016] When using this utility model, the height of the empty box structure and the width of the foundation surface can be designed according to the allowable bearing capacity of the foundation and the height of the free surface; according to the actual required width of the cantilevered platform and the upper load, the comprehensive center of gravity C2 of the dynamic load is calculated, thereby obtaining the distance between the fulcrum 2 and the comprehensive center of gravity C2, i.e., the length of the dynamic arm L2; then according to the formula requirement G1×L1≥2×G2×L2, the size of the counterweight block 6 and the length of the resistance arm L1 are comprehensively determined, thereby realizing the widening of the free surface of traffic roads, the cantilevered leisure platform on the free surface, the widening of the flood control road on the river, and the cantilevered waterfront platform on the river.

[0017] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
