Description

Grouting reinforced module assembly type special-shaped steel pipe beam column joint

Technical Field

The utility model relates to an assembly type structure technical field, concretely relates to module assembly type structure beam column nodal connection mode.

Background

Different from the traditional building construction mode, the construction mode of the module assembly type building is as follows: the method comprises the steps of dividing a structure into single room unit modules, completing the structure construction, indoor decoration, water and electricity installation and the like of each unit module in a factory, transporting the prefabricated unit modules to the site, hoisting the prefabricated unit modules by using a crane, and finally connecting the prefabricated unit modules into a whole structure. The modular prefabricated building is generally transported to a site for lifting by using a truck or the like, and the area of each unit module is limited by the size of the vehicle, so that the area of a single room of the modular prefabricated building is generally small. In addition, the current module assembly type building is generally used for government-dominated building rooms such as a low-cost house and an economically applicable house, and the design area of a single room of the rooms is small. If rectangular or square steel pipe columns are used, an indoor convex angle is formed at the corner of a room, so that the attractiveness of the house is affected, and the using area of the building is reduced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a grout enhancement mode module assembled dysmorphism steel pipe beam column node is designed for L shape dysmorphism steel-pipe column through the post with the unit module to solve the indoor salient angle problem among the modularization building commonly used at present. In order to achieve the above purpose, the utility model discloses a connecting plate, internal connection spare, backing plate between L shape dysmorphism steel-pipe column, rectangle roof beam, bolt, roof beam, wherein internal connection spare includes internal connection steel pipe, shear key one and cross trompil steel sheet.

Furthermore, the inner wall of the grouting part of the L-shaped special-shaped steel pipe column is provided with a shear key II, and the shear key II can be formed by welding reinforcing steel bars on the inner wall of the L-shaped special-shaped steel pipe column or surfacing welding materials.

Furthermore, the outer wall of the internal connecting piece is provided with a shear key I, and the shear key I and a shear key II of the special-shaped steel pipe column are arranged in a staggered mode.

Further, the L-shaped special-shaped steel pipe columns of different modules are connected through an internal connecting piece, the column connection between the upper and lower adjacent modules and the column connection between the horizontal adjacent modules are included, and grouting materials are poured into the region gap with the shear keys in the later stage.

Furthermore, the two rectangular beams of the upper module and the lower module are connected with the connecting plate and the base plate between the beams through bolts.

Further, after the L-shaped special-shaped steel pipe column and the internal connecting piece are installed and the upper module rectangular beam and the lower module rectangular beam are connected, high-strength grouting materials are poured into gaps in the shear key arrangement area between the internal connecting piece and the L-shaped special-shaped steel pipe column.

The utility model discloses an useful part lies in can not forming indoor salient angle, does benefit to the space utilization, increases the usable floor area of module assembly type structure.
