The syndeton of a kind of concrete frame post and steel roof joistTechnical field
The present invention relates to building field, is the syndeton of a kind of concrete frame post and steel roof joist specifically.
Background technology
Single-storey factory building often makes concrete frame post, light roof.Prior art complex structure, installation is wasted time and energy, and conveniently installs, and the process maintenance brick wall at cornice place and the relation that sockets of bent columns are problems needing to solve better.
Summary of the invention
For solving the problems of the technologies described above, the present invention does bracket and is connected with girder steel on bent columns.Utilize the embedded part on shear key and bracket top and girder steel to be connected, the effect of Transfer of Shear can be played, also achieve being articulated and connected of girder steel and bent columns simultaneously.Concrete technical scheme is as follows:
A syndeton for concrete frame post and girder steel, the embedded part of pre-buried strap crab-bolt on bracket; Described embedded part arranges backing plate, described backing plate arranges girder steel, the stay bolt correspondence position of described girder steel and embedded part arranges through hole, and stay bolt is through after described through hole, and tighten with nut, described backing plate both sides are bearing place, and described bearing place builds slightly expanded concrete.
Described embedded part comprises location-plate, lower location-plate, and multiple stay bolt is fixed with upper location-plate, lower location-plate respectively.
Also arrange angle steel shear key to be welded and fixed with embedded part and girder steel respectively.
Described backing plate height adjustable.
Between described upper location-plate, lower location-plate, many stiffeners are set; Described stiffener and upper mounted plate are welded and fixed.
The side of fixed plate is fixed with angle steel.
Become hook-shaped bottom described stiffener.
Advantage of the present invention is: utilize built-in fitting, and not only intensity increases, and uses shear key to weld with the embedded part on bracket and girder steel respectively, achieves being articulated and connected of girder steel and bent columns.

Detailed description of the invention
The present invention is illustrated below in conjunction with accompanying drawing, as shown in Figure 1 and Figure 2, the embedded part 1 of pre-buried strap crab-bolt on bracket; Described embedded part 1 arranges backing plate 2, described backing plate 2 arranges girder steel 5, described girder steel 5 arranges through hole with stay bolt 11 correspondence position of embedded part 1, stay bolt 11 is through after described through hole, tighten with nut, described backing plate 2 both sides are bearing place 4, and described bearing place 4 builds slightly expanded concrete.
As shown in Figure 3, described embedded part comprises location-plate 12, lower location-plate 13, and multiple stay bolt 11 is fixed with upper location-plate 12, lower location-plate 13 respectively.
Also arrange angle steel shear key 3 respectively with embedded part 1) girder steel 5 is welded and fixed.
Described backing plate 2 height adjustable.
Between described upper location-plate 12, lower location-plate 13, many stiffeners 14 are set; Described stiffener 14 is welded and fixed with upper mounted plate 12.
The side of fixed plate 12 is fixed with angle steel 15.
