Abstract
The utility model relates to a steel purlin support structure which is simple in structure and convenient for construction, so as to strength the shearing resistance and sliding resistance of steel purpins at inclined support parts and ensure the stability of foundation pit support structure systems. The technical scheme is that the steel purlin support structure comprises a steel purlin and a group of guard posts which are arranged along the length direction of the steel purlin; the guard posts are all located at the same side of the steel purlin; and concrete is poured between the steel purlin and the guard posts as well as the guard posts. The steel purlin support structure is characterized in that a group of angle steel is welded on the steel purlin at the side toward the guard posts and the angle steel is fixedly embedded in the concrete. The steel purlin support structure is suitable for the guarding and supporting of railway station foundation pits or other large-scale foundation pits.
Description
Technical field
The utility model relates to a kind of steel and encloses the purlin braced structures, mainly is applicable to the support of going along with sb. to guard him of subway station foundation ditch or other large-scale foundation ditches.
Background technology
At present in subway foundation pit or other the large-scale foundation ditches, adopt multiple tracks to support, and Two bors d's oeuveres H shaped steel enclose purlin because of its rigidity is big, easy construction and recyclable utilization are used in a large number more.Popularize along with what steel supported in recent years, the steel support is more and more with the situation that shaped steel encloses the purlin oblique, and this shearing resistance, antiskid that just needs reinforcement H shaped steel to enclose between purlin and the fender post moves measure.
Summary of the invention
The technical problem that the utility model will solve is: the problem to above-mentioned existence provides a kind of steel simple in structure, easy construction to enclose the purlin braced structures, and the shearing resistance and the antiskid of enclosing purlin with reinforcement diagonal brace position steel move ability, guarantee the stable of foundation ditch braced structures system.
The technical scheme that the utility model adopted is: steel encloses the purlin braced structures; Comprise that steel encloses purlin; And enclose one group of fender post that the purlin length direction is arranged along steel, and and each fender post all is positioned at the same side that steel encloses purlin, said steel encloses between purlin and the fender post, concreting between adjacent two fender posts; It is characterized in that: said steel encloses on the purlin, is connected to one group of angle steel towards fender post one face down bonding, and each angle steel all fixedly is embedded in the concrete.
Said steel encloses and evenly is welded with one group of stiffener on the purlin.
It is that Two bors d's oeuveres H shaped steel encloses purlin that said steel encloses purlin.
Said angle steel is along in three parallel edges of its length direction, and the gap between adjacent two fender posts is pointed on a limit at corresponding knuckle place, and all the other two limits then are welded in steel and enclose on the purlin.
The beneficial effect of the utility model is: the utility model encloses on the purlin, connects one group of angle steel near fender post one face down bonding at steel; Angle steel was completely fixed and is embedded in the concrete after construction was accomplished; Utilize angle steel and steel to enclose the weld force between the purlin; And the adhesion stress between angle steel and the concrete, strengthen shearing resistance and antiskid that steel encloses purlin and moved ability, improved the stability of whole support system.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; Enclose purlin 1 oblique because steel supports 6 with steel, promptly between the two angle is an acute angle, makes steel enclose purlin 1 and has the possibility that moves along its length direction; Therefore present embodiment encloses purlin to existing steel and carries out structural optimization, promptly welds one group of angle steel 4 above that.Steel after the present embodiment utilization improves encloses the layout that purlin carries out braced structures; It comprises that specifically Two bors d's oeuveres H shaped steel encloses purlin 1; And enclose one group of fender post 2 that purlin 1 length direction is arranged along steel; The line in each fender post 2 axle center is parallel to steel and encloses purlin 1 length direction in this example, and all is positioned at the same side that steel encloses purlin 1; Said steel encloses on the purlin 1, is connected to one group of angle steel 4 towards fender post 2 one face down bondings; Angle steel 4 length directions and fender post 2 parallel axes; Angle steel 4 has three parallel limits along its length direction; Wherein the gap between adjacent two fender posts 2 is pointed on corresponding limit, knuckle place, and all the other two limits then are welded in steel and enclose on the purlin 1; Enclose between purlin 1 and each fender post 2 at steel at last; And concreting between adjacent two fender posts 2 (adopting the fast hard pea gravel concreten of C30) 3, treat that concrete 3 solidifies fully after, angle steel 4 is completely fixed and is embedded in the concrete 3; Utilize angle bar 4 and steel to enclose the weld force between the purlin 1; And the adhesion stress between angle steel 4 and the concrete 3, shearing resistance and antiskid that the reinforcement steel encloses purlin 1 move ability, thereby have improved the stability of whole support system.
Said steel encloses and evenly is welded with one group of stiffener 5 on the purlin 1, to strengthen the intensity that steel encloses purlin 1 self.
