Abstract
本实用新型提供了一种外包钢-混凝土叠合板组合梁的C型钢梁，C型钢梁采用花纹钢板冷弯制成，其上翼缘向下弯折形成折边。本实用新型采用花纹钢板制成的C型钢梁，成型方便；其内表面布设有花纹样凸起，花纹的凸起需满足一定的高度要求，从而有效增大外包钢梁与混凝土的粘结咬合作用；折边的设置同样具有C型钢梁与混凝土的粘结增强作用。
The utility model provides a C-shaped steel girder which is wrapped with steel-concrete laminated slab composite girders. The C-shaped steel girder is made by cold-bending patterned steel plates, and the upper flange of the C-shaped steel girder is bent downward to form a hem. The utility model adopts the C-shaped steel beam made of patterned steel plate, which is easy to form; its inner surface is provided with pattern-like protrusions, and the protrusions of the pattern need to meet a certain height requirement, so as to effectively increase the bonding between the outsourcing steel beam and the concrete Occlusion; the setting of the folded edge also has the effect of strengthening the bond between the C-shaped steel beam and the concrete.
Description
Technical field
The utility model belongs to the building structure technology field, is specifically related to a kind of C section steel beam that is applied to the outsourcing steel-concrete folding plate combined beam of steel house industrialization.
Background technology
Steel-precast concrete folding plate combined beam in the present steel house, girder steel adopts I-shaped or H shape girder steel more, and prefabricated panel is placed on the top flange of girder steel, combines stressed jointly between girder steel and the superimposed sheet by shear connector.Shear connector generally adopts peg, is welded on the girder steel top flange, and the welding job amount is big, and the performance of collaborative work also has much room for improvement between concrete prefabricated base plate and the girder steel simultaneously.
If in steel house, adopt the compound beam of girder steel outsourcing, the concrete of filling in the beam rib and the facing concrete on the concrete prefabricated base plate are whole to be watered, can effectively guarantee the globality of concrete prefabricated base plate and compound beam, therefore external Baogang-concrete folding plate combined beam, crucial problem are to solve outsourcing girder steel and concrete co-operation problem.
The utility model content
At the problem that above prior art exists, the utility model provides C section steel beam a kind of and the outsourcing steel-concrete folding plate combined beam that the concrete binding performance is good.
The utility model is achieved through the following technical solutions:
A kind of C section steel beam of outsourcing steel-concrete folding plate combined beam, described C section steel beam adopt the checkered steel plate clod wash to make, and its top flange is to being bent to form flanging downwards.
Angle between described flanging and top flange is 90 °.
Described C section steel beam inner surface is laid with decorative pattern sample projection.
The beneficial effects of the utility model are: the C section steel beam that adopts checkered steel plate to make, convenient formation; Its inner surface is laid with decorative pattern sample projection, and the projection of decorative pattern need satisfy the certain height requirement, thereby effectively increases outsourcing girder steel and concrete bonding interlocking; Arranging of flanging has C section steel beam and concrete bonding humidification equally.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 is the C section steel beam; 2 is the top flange; 3 is flanging.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
The utility model provides a kind of C section steel beam of outsourcing steel-concrete folding plate combined beam, C section steel beam 1 adopts the checkered steel plate clod wash to make, therefore its inner surface is laid with decorative pattern sample projection, and its top flange 2 is bent to form flanging 3 downwards, and the angle of 2 of flanging 3 and top flanges is 90 °.
The C section steel beam 1 that the utility model adopts checkered steel plate to make, convenient formation; Its inner surface is laid with decorative pattern sample projection, and the projection of decorative pattern need satisfy the certain height requirement, thereby effectively increases outsourcing girder steel and concrete bonding interlocking; Arranging of flanging 3 has C section steel beam and concrete bonding humidification equally.
