In Wavelike steel webplate combined bridge structure, between Wavelike steel webplate with concrete, the general shear connector that adopts is combined, its connecting portion becomes the key link of design, should guarantee that vertical equity shearing can effectively transmit, guard box beam section each several part is integrally formed formula structure and bears load simultaneously simultaneously.
Traditional Wavelike steel webplate combined bridge web and concrete floor adopt edge of a wing type connector and embedded type connector to be connected usually.Edge of a wing type connector is at Wavelike steel webplate welding edges one block of plain plate, steel plate is welded with some welderings nail, open pore steel plate or shaped steel, runs through reinforcing bar and play connection function; Embedded type connector is that Wavelike steel webplate directly inserts concrete floor, and its end perforate also arranges and runs through reinforcing bar and play connection function.Under the type connector edge of a wing, the above-mentioned edge of a wing, concrete needs reverse building, and its service behaviour and construction quality are affected, and waterproofing work must be taked in embedded type connector interface in construction and later maintenance, and durability is poor.Therefore, research and design goes out a kind of reasonable stress, working drawing review connecting structure tool that is convenient, economy and durability is of great significance.
Because the defect that the connected mode of above-mentioned existing Wavelike steel webplate and concrete floor exists, the present inventor is based on being engaged in the practical experience and professional knowledge that this type of product design manufacture enriches for many years, and coordinate the utilization of scientific principle, actively in addition research and innovation, to founding a kind of connecting structure of bottom plate of wave forms steel web, it is made to have more practicality.Through constantly research, design, and through repeatedly studying sample and after improving, finally creating the present invention had practical value.
Summary of the invention
Main purpose of the present invention is, the defect that the connected mode overcoming existing Wavelike steel webplate and concrete floor exists, and a kind of connecting structure of bottom plate of wave forms steel web is provided, improve shear strength, thus be more suitable for practicality, and there is the value in industry.
The object of the invention to solve the technical problems realizes by the following technical solutions.The connecting structure of bottom plate of a kind of Wavelike steel webplate proposed according to the present invention, includes Wavelike steel webplate, concrete floor and connects the outer-enwraped type steel plate structure of Wavelike steel webplate and concrete floor;
Described Wavelike steel webplate is fixed on the upper surface of described outer-enwraped type steel plate structure, described outer-enwraped type steel plate structure one end open, and is arranged on concrete floor one end external surface, is connected by described Wavelike steel webplate with concrete floor.
Further, the connecting structure of bottom plate of aforesaid Wavelike steel webplate, described outer-enwraped type steel plate structure is made up of plate top surface plain plate, the vertical plain plate of base plate, base plate bottom surface plain plate, described plate top surface plain plate and the setting parallel to each other of base plate bottom surface plain plate, what the vertical plain plate of described base plate the was vertical one end part be arranged between described plate top surface plain plate and base plate bottom surface plain plate is put, wherein the vertical plain plate of base plate and being welded and fixed mutually between plate top surface plain plate and base plate bottom surface plain plate.
Further, the connecting structure of bottom plate of aforesaid Wavelike steel webplate, the plate top surface plain plate in described outer-enwraped type steel plate structure, the vertical plain plate of base plate and base plate bottom surface plain plate fix with concrete floor respectively by weldering nail.
Further, the connecting structure of bottom plate of aforesaid Wavelike steel webplate, the length of described base plate bottom surface plain plate is greater than the length of plate top surface plain plate.
By technique scheme, the connecting structure of bottom plate of Wavelike steel webplate of the present invention at least has following advantages:
The connecting structure of bottom plate of Wavelike steel webplate of the present invention, has the plain plate of weldering nail that concrete floor is carried out outsourcing connection by three block weldings, increases the connection area of Wavelike steel webplate and concrete floor, thus strengthen bonding strength; The externally-packed structure of three pieces of plain plate compositions, avoids the problem that when underplate concrete is built, outboard template is set up and concreting difficulty is large; The outer-enwraped type steel plate structure external wrapping concrete base plate that the welding of three blocks of plain plates is formed, avoids binding site concrete, steel and water three and to contact the problem of the structure durability difference caused.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of manual, be described in detail as follows below with preferred embodiment of the present invention.
