Abstract

A roof steel bent with a profiled steel plate arched shell structure relates to a safe reinforcement structure for preventing a roof of the profiled steel plate arched shell structure from collapsing. The utility model is made by the method that an arched plate is reinforced by angle steel and then reinforced by two crossed steel tie rods; two longitudinal steel tie rods are connected between every two of the steel bents; the utility model can also be formed by the method that a crossed position of the two crossed steel tie bars is additionally provided with a transverse steel tie rod; the three steel tie rods form a shape like the Chinese character 'mi', and the crossed position is provided with a steel pull plate. Mounted under the roof of the profiled steel plate arched shell structure, the utility model has the advantages of effectively stability enhancement, collapse prevention, long service life, little material and low cost. The reserve factor of safety can be increased.

Description

Profiled sheet arch shell structure roofing steel framed bent

The utility model relates to a kind of safe reinforcement that prevents that profiled sheet arch shell structure roofing from caving in.

Profiled sheet arch shell structure roofing technique late nineteen eighties originates from the U.S., the early 1990s is introduced China, steel using amount is little because it has, and cost is low, and span is big, moulding U.S., advantages such as it is fast to construct, thus sweep the country very soon, but because its resistance to overturning is poor, the safety stock coefficient is low, causes casualties and the thing of property loss often has generation because of roofing caves in.

The purpose of this utility model provides a kind of profiled sheet arch shell structure roofing steel framed bent, and it can increase the stability of profiled sheet arch shell structure roofing effectively, improves the safety stock coefficient, prevents to cave in, and increases the service life.

The purpose of this utility model is achieved in that arranges some arch form steel framed bents as required below profiled sheet arch shell structure roofing, the curvature of steel framed bent arch form and roofing arch bar keeps uniformity.After the steel framed bent is strengthened by arch bar 1 usefulness angle steel 2 shaped steel such as grade, steel tie-rod 3 with two intersections is strengthened making, article two, the lower end of the steel tie-rod of intersection is connected and fixed with the two ends of steel framed bent bottom respectively, the upper end is connected and fixed with 1/3 place and 2/3 place of steel framed bent arch, between steel framed bent and steel framed bent, be connected, vertically on the tie point at 1/3 place of the steel tie-rod steel tie-rod upper end that is welded on two intersections and steel framed bent arch and 2/3 place with two vertical steel tie-rods 5.

In order to make the utility model more solid and reliable, can cross the infall of two intersection steel tie-rods and set up the steel tie-rod 4 that a horizontal line with between steel framed bent arch two ends, bottom parallels again, its two ends are fixing with the both sides welding of steel framed bent arch respectively, like this, article three, the steel tie-rod is formed a M shape, we can establish steel arm-tie 6 at its infall, and three steel tie-rods all are welded on the steel arm-tie 6.

For solid and reliable, can also be to the upper end of two intersection steel tie-rods 3, promptly the above 3 ＇ intensity partly in crosspoint is strengthened, and makes of steel pipe, channel-section steel or angle steel, to strengthen its bearing capacity.

The utility model has the advantages that the stability that can increase profiled sheet arch shell structure roofing effectively, improve the safety stock coefficient, prevent to cave in, increase the service life; And take this structure material few, cost is low, and is easy to utilize.

Fig. 1 is the front view of the utility model structure;

Fig. 2 is the sectional view of Fig. 1 along the C-C line.

Below in conjunction with accompanying drawing the utility model is further described:

With reference to Fig. 1, flute profile arch bar 1 welds together with reinforcement angle steel 2, the height of flute profile arch bar stile should be consistent with the height of roofing trough slab stile, strengthen angle steel 2 and also can select shaped steel such as steel pipe, channel-section steel for use, article two, the lower end of the steel tie-rod 3 of intersection is welded in the two ends, bottom of strengthening angle steel 2 respectively, the upper end is welded in 1/3 place and 2/3 place that strengthens angle steel respectively, be connected with two vertical steel tie-rods 5 between steel framed bent and steel framed bent, vertically the steel tie-rod is welded on the tie point at steel tie-rod 3 upper ends and 1/3 place that strengthens angle steel and 2/3 place of two intersections of each steel framed bent; Another kind of scheme is to set up the steel tie-rod 4 that a horizontal line with between steel framed bent arch two ends, bottom parallels at the infall of crossing two intersection steel tie-rods on the basis of said structure, its two ends are welded in the both sides that steel framed bent arch is strengthened angle steel respectively, these three steel tie-rods are formed a M shape, its infall is established steel arm-tie 6, and they all are welded on the steel arm-tie; Another design is that its structure is constant, and just with the upper end of two intersection steel tie-rods 3, promptly 3 above ＇ of crosspoint partly select for use the higher steel pipe of intensity, channel-section steel or angle steel to make.

With reference to Fig. 1 and Fig. 2, suitable space can be stayed in steel framed bent and roofing arch bar 7 junctions during concrete the making, with being cut into banded rubber tile 8 pads in the gap, the steel framed bent is made the back and is formed lifting elements with roofing arch bar 7 according to the fit form of Fig. 2, and lower end and the wall support steel supporting plate 9 of strengthening angle steel 2 behind the hoisted in position weld together.

Claims

1, profiled sheet arch shell structure roofing steel framed bent, after it is characterized in that the steel framed bent is strengthened with angle steel [2] by arch bar [1], strengthen making with the steel tie-rod [3] of two intersections, article two, the lower end of the steel tie-rod of intersection is connected and fixed with the two ends of steel framed bent bottom respectively, the upper end is connected and fixed with 1/3 place and 2/3 place of steel framed bent arch, between steel framed bent and steel framed bent, be connected, vertically on the interface point at 1/3 place of the steel tie-rod steel tie-rod upper end that is welded on two intersections and steel framed bent arch and 2/3 place with two vertical steel tie-rods [5].

2, according to the described profiled sheet arch shell structure of claim 1 roofing steel framed bent, the infall that it is characterized in that two intersection steel tie-rods is set up the steel tie-rod [4] that a horizontal line with between steel framed bent arch two ends, bottom parallels again, its two ends are fixing with the both sides welding of steel framed bent arch respectively, like this, article three, the steel tie-rod is formed a M shape, we establish steel arm-tie [6] at its infall, and three steel tie-rods all are welded on the steel arm-tie [6].
