Abstract

A hidden node structure of a steel beam works together with building boards and/ or internal wallboards and external wallboards. The nature of the steel beam is the irregular H-shaped section steel. The steel beam and the building board are arranged on one same plane to form a plane butt joint, the gap at the butt joint is filled with concrete in situ to be fixedly connected into a whole, and steel beam is covered and hidden inside the node of the building board to form the structure which is not exerted. The utility model is provided with a simple technology and is convenient for constructing, and also can solve the problems of fireproofing and corrosion resisting of the steel structure well at low operating costs.

Description

A kind of girder steel concealed type node structure

Technical field

The utility model relates to the building node structure, specifically a kind of girder steel concealed type node structure that is used for steel house.

Background technology

In the steel house construction, a ubiquitous difficult problem is anticorrosion, the fire prevention of steel work, adopt the fire prevention steel and take anti-corrosion measure cost height, technology is difficult to guarantee, how to select a kind of can be economic and practical, technical guarantee is arranged again, and the building node structure of easy construction is an important ring of modernization of the housing industry.Therefore, prior art has improves perfect necessity, and new building node structure scheme is provided.

Summary of the invention

The purpose of this utility model provides a kind of girder steel concealed type node structure, technical matters is simple, and easy construction can solve fire prevention, the anticorrosion difficult problem of steel work preferably, and operating cost is lower.

The purpose of this utility model is achieved in that

A kind of girder steel concealed type node structure is used with building floor and/or inside and outside wallboard, it is characterized in that:

The material of girder steel is special-shaped H shape shaped steel;

Girder steel with become the plane butt joint in building floor is arranged on same plane, filling out affixed with Cast-in-place concrete in the space of joint be integral body, the girder steel coating is hidden the structure that does not expose in floor intranodal one-tenth.

The purpose of this utility model can also realize by following measure:

Described girder steel can be a spandrel girder, also can be non-spandrel girder.

The section shape of the mouth as one speaks of described special-shaped H shaped steel is not wait the special-shaped H shaped steel on the edge of a wing.

Described floor is a composite floor plate, it becomes steel frame by some truss bar assembly weldings, place the heat insulating and sound insulating layer in the middle of it, the bending part of truss bar is exposed at its two ends respectively, this truss bar is by upper chord, lower chord, continuous wave brace assembly welding forms, and in steel frame upper and lower surface pouring the light weight concrete construction layer is arranged.

The spandrel girder both sides of described special-shaped H shaped steel, to taking dowel, exposed lower chord and steel spandrel girder are welded together by the exposed upper chord of floor, and non-bearing girder steel both sides overlap with the floor steel frame up and down with the steel mesh sheet and are held together the two sides Cast-in-place concrete.

In the described compound fishplate bar that docks with girder steel, hidden the floor pipeline.

The utility model has following actively useful effect

This structure adopts hot rolling abnormity H shaped steel to make Vierendeel girder, cooperates with cage of reinforcement light thermal-insulation sound insulation composite floor plate, and girder steel is hidden in floor; The utility model brings layout simultaneously easily to housing construction, has solved anticorrosion, the fire prevention difficult problem of girder steel, and technical matters is simple, easy construction, operating cost are lower.

Specific embodiment

Please refer to Fig. 1 to Fig. 6, the utility model is a kind of girder steel concealed type node structure, is used with building floor and/or inside and outside wallboard, it is characterized in that:

The material of girder steel 1 is hot rail abnormity H shape shaped steel;

Girder steel 1 with become the plane butt joint in building floor 2 is arranged on same plane, filling out affixed with Cast-in-place concrete 3 in the space of joint be integral body, girder steel 1 coating is hidden the structure that does not expose in the intranodal one-tenth of floor 2.

Described girder steel 1 can be a spandrel girder, also can be non-spandrel girder.

The section shape of the mouth as one speaks of described hot rolling abnormity H shaped steel 1 is not wait the special-shaped H shaped steel on the edge of a wing (wing plate), for example the edge of a wing, two ends is low wide and up narrow, the special-shaped H shaped steel of going up the long right short type in a left side is seen Fig. 8, or the edge of a wing, two ends is low wide and up narrow, and the symmetrical special-shaped H shaped steel in top flange is seen Fig. 9.

Fig. 1, embodiment illustrated in fig. 4 in, described floor is a composite floor plate, it becomes steel frame by some truss bar assembly weldings, place the heat insulating and sound insulating layer in the middle of it, its two ends are exposed portions serve truss bar respectively, and this truss bar is by upper chord 203, lower chord 204, and continuous wave brace 205 assembly weldings form.In steel frame upper and lower surface pouring light weight concrete construction 208 is arranged.

The spandrel girder both sides of described hot rolling abnormity H shaped steel, take dowel 205 by exposed 203 pairs of the upper chords of floor, exposed lower chord 204 is welded together with the steel spandrel girder, non-bearing girder steel both sides overlap and are held together into non-bearing with the floor steel frame with the steel mesh sheet about in the of 206 and kidnap beam 207, two sides Cast-in-place concrete.
