Abstract
The utility model provides a I -steel supports for strength nature steel construction, shaped steel girder steel set up in concrete beam, the fixed foundation structure who constitutes whole support of each steel pipe support interconnect, bottom side template settings is at steel pipe support's top, the I -steel cushion is laid in the template of concrete beam's bottom side along span direction equidistance interval, the top of I -steel cushion contacts with concrete beam's bottom, has the spacing distance between I -steel cushion and the shaped steel girder steel. This structure replaces traditional cross arm to support, and the shaped steel girder steel transmits the whole foundation structure who supports of lower floor after using the I -steel cushion, has solved large -span shaped steel beam deflection control problem effectively, and the while has also been overcome traditional cross arm support piece and has been built in the roof beam difficult problem that intercepting then influences dry mass.
Description
Technical field
The utility model relates to a kind of belt distance i iron support member for stiffened steel structure, belongs to long-span beams structure applied technical field.
Background technology
Reinforced concrete composite structure is a kind of new composite structure being better than steel work, concrete structure also known as stiffened steel structure, but not to be two kinds of form of structure simply combine for it, but two kinds of form of structure collocation in construction technology and the complementation of material behavior, this form of structure is newer, be usually used in long-span beams structure, there is excellent functional performance and wide application prospect in future development.As shown in Figure 1, shaped steel girder steel is arranged in concrete beam; And large-span steel girder is executed man-hour requirement and is controlled its amount of deflection, the amount of deflection produced due to deadweight make in the middle part of girder steel sagging even with template laminating, cause beam bottom concrete thickness to affect whole beam stress not.
Be illustrated in figure 2 traditional amount of deflection and control constructing structure, do cross binding at steel beam bottom steel pipe, steel pipe two ends are connected with bracing frame.There is following shortcoming in this structure: 1) steel pipe span is larger stressed yielding; 2) steel pipe is arranged in steel beam bottom and through whole beam, affects side form formwork; 3) built concrete and need cut off steel pipe, expense of taking a lot of work material and unsightly; 4) residual steel pipe is hollow, has impact to stressed.
Summary of the invention
For solving the existing defect described in background technology, the structure that the utility model adopts is a kind of stiffened steel structure of belt distance i iron support member, and this structure comprises shaped steel girder steel 1, concrete beam 2, steel pipe support 3, bottom side template 4, i iron cushion block 5; Shaped steel girder steel 1 is arranged in concrete beam 2, and each steel pipe support 3 is interconnected and fixed the foundation structure of composition integrated support; Bottom side template 4 is arranged on the top of steel pipe support 3; I iron cushion block 5 is laid in the bottom side template 4 of concrete beam 2 along pitch spacings such as span directions; The top of i iron cushion block 5 and the bottom connection of concrete beam 2 touch, and there is spacing distance between i iron cushion block 5 and shaped steel girder steel 1.
Traditional cross-arm is replaced to support at the bottom of direct support type girder steel, shaped steel girder steel 1 is delivered to the foundation structure of lower floor's integrated support after being applied to i iron cushion block 5, efficiently solve large span section steel beam amount of deflection control problem, also overcome traditional cross-arm support member simultaneously and be cast in the difficult problem then intercepting in beam and affect architecture quality.
Spacing distance between i iron cushion block 5 and shaped steel girder steel 1 depends on model and the stressed size of shaped steel girder steel 1 of shaped steel girder steel 1.
Compared with prior art advantage: 1) i iron supports to be interrupted and arranges, consumption is little; 2) be stressedly axial vertical force to stable rigid template support, effectively control amount of deflection; 3) do not affect side form to install; 4) i iron cushion block directly imbeds concreting, need not cut afterwards, and does not closely knitly expose, and does not affect quality.

Fig. 2 is that traditional amount of deflection controls constructing structure figure.
Fig. 3 is the stiffened steel structure figure of belt distance i iron support member.
In figure: 1, shaped steel girder steel, 2, concrete beam, 3, steel pipe support, 4, bottom side template, 5, i iron cushion block.
Detailed description of the invention
As Figure 1-3, a kind of i iron for stiffened steel structure supports, and this structure comprises shaped steel girder steel 1, concrete beam 2, steel pipe support 3, bottom side template 4, i iron cushion block 5; Shaped steel girder steel 1 is arranged in concrete beam 2, and each steel pipe support 3 is interconnected and fixed the foundation structure of composition integrated support; Bottom side template 4 is arranged on the top of steel pipe support 3; I iron cushion block 5 is laid in the bottom side template 4 of concrete beam 2 along pitch spacings such as span directions; The top of i iron cushion block 5 and the bottom connection of concrete beam 2 touch, and there is spacing distance between i iron cushion block 5 and shaped steel girder steel 1.
Traditional cross-arm is replaced to support at the bottom of direct support type girder steel, shaped steel girder steel 1 is delivered to the foundation structure of lower floor's integrated support after being applied to i iron cushion block 5, efficiently solve large span section steel beam amount of deflection control problem, also overcome traditional cross-arm support member simultaneously and be cast in the difficult problem then intercepting in beam and affect architecture quality.
Spacing distance between i iron cushion block 5 and shaped steel girder steel 1 depends on model and the stressed size of shaped steel girder steel 1 of shaped steel girder steel 1.
