Description
Technical Field
The utility model relates to the technical field of constructional engineering, in particular to a frame bridge pull-rod-free mobile trolley construction device.
Background
With the progress of modern society, traffic pressure is getting bigger and bigger. Road traffic lines are mutually staggered, ground traffic cannot completely meet the requirements, and various bridges need to be erected to realize the longitudinal and transverse crossing of vehicles such as trains or automobiles. Compared with bridge types such as an arch bridge, a truss bridge and the like, the frame bridge has the characteristics of simple structure, good integrity, low manufacturing cost and easiness in construction, the section of the frame bridge is of a frame box structure, the top surface of the frame bridge bears vehicles to run, the bottom surface of the frame bridge is paved, and vehicles in the other direction run through the bottom surface.
The frame bridge forms for reinforced concrete monolithic pouring usually, at first carries out the basis excavation and lays the terrace, then carries out the prefabrication of box on the terrace: binding the reinforcing steel bars of the bottom plate template, supporting and reinforcing the bottom plate template, and pouring a bottom plate of the box body; binding the reinforcing steel bars of the wall body and supporting the wall body by using a template, and pouring the wall body; and finally, binding steel bars of the top plate and supporting a template, and pouring the top plate. In the prefabrication process of the box body, a full support is usually required to be built inside the box body, and an outer side formwork support is built on the outer side surface of the box body. When the wall body is poured, the outer side wall template is fixed on the outer side template support, the inner side wall template is fixed on the full hall support in the box body, in order to keep the highly uniform of interval between the inner and outer templates, generally, an anchor pull rod is penetrated between the inner side template and the outer side template, the interval between the inner and outer side templates is anchored, the thickness of the wall body finally poured can be accurately leveled, and the concrete finally solidifies the pull rod package into a whole. However, the tie-rod anchor bolt inside and outside template also has the following disadvantages: 1. the work of installing the anchor bolt pull rod is labor-consuming and time-consuming, and a large amount of labor cost is consumed; 2. the use of a large number of pull rods improves the cost of the building materials of the whole project; 3. the pull rod can be retained in concrete sometimes, under the condition, the pull rod head is exposed on the surface of a concrete structure after the concrete is poured finally, the flatness of the surface of the frame bridge is influenced, the aesthetic degree of a building is reduced, the pull rod head needs to be manually cut off in serious cases, and certain labor cost is consumed; after a long time, the tie rod head is corroded to influence the steel bars in the building structure, so that the building safety is influenced; 4, if the pull rod is pulled out after the concrete pouring is finished, a hole is left in the concrete structure, and the water seepage and the water prevention of the building are not facilitated.
