Abstract
The invention discloses arched corrugated steel roof with improved use span and method for improving the use span of the arched corrugated steel roof. The arched corrugated steel roof is characterized in that a linear oblique beam is arranged at the inner side of the upper part of a cylinder or an overhanging arc-shaped beam is arranged at the top of the cylinder, a longitudinal auxiliary support for roof is arranged at the top of the linear oblique beam or the overhanging arc-shaped beam and supported below the arched corrugated steel roof, and the supporting point has a certain distance away from the cylinder. The linear oblique beam or the overhanging arc-shaped beam having the same radian as the arched corrugated steel roof serves as an auxiliary beam and can be made of a reinforced concrete or steel structure. According to the invention, a method of arranging the auxiliary beam on the lower cylinder of the arched corrugated steel roof and arranging the longitudinal auxiliary support for the roof at the top of the auxiliary beams is adopted, so that the practical calculated span of the arched corrugated steel roof is reduced, and the practical use span of the arched corrugated steel roof is effectively increased, thus achieving the purpose of improving the use space of the arched corrugated steel roof.
Description
Technical field
The present invention relates to a kind of construction work design and building, relate in particular to a kind of properties of arched corrugated steel roof and method of using span that improve.
Background technology
Properties of arched corrugated steel roof is the assembled self-supporting arch cover of unit board that Coil Coating Products is rolled into given shape by special equipment.Be a kind of technology maturation and widely used roof system form.Country issued " properties of arched corrugated steel roof structure technology rules " (CECS167:2004) in 2004, and these rules are applicable to that span is not more than the properties of arched corrugated steel roof design of 30M, makes and install.The domestic properties of arched corrugated steel roof span that adopts is controlled in the 30M basically at present, and simultaneously in crushing by snow and blast larger area, the properties of arched corrugated steel roof span makes it use span littler because of the restriction of supporting capacity.
In the actual demand to properties of arched corrugated steel roof, a lot of occasions often need the restriction of the span of properties of arched corrugated steel roof greater than 30M, produce contradiction between the demand in market and the prior art.
Thereby prior art awaits to improve and improve.
Summary of the invention
The object of the present invention is to provide a kind of large span, grand, safe, can improve existing properties of arched corrugated steel roof and the method for using span.
Technical scheme of the present invention comprises:
A kind of properties of arched corrugated steel roof of using span that improves, comprise properties of arched corrugated steel roof and cylinder, wherein, upper inner leg place at described cylinder is provided with floor stringer, the top of floor stringer is provided with the vertical auxiliary support of roof system, vertically auxiliary support is supported on properties of arched corrugated steel roof bottom, and the strong point is apart from the cylinder certain distance.
The properties of arched corrugated steel roof of span is used in described raising, wherein, described floor stringer comprise the straight line cant beam, with the arc beam of encorbelmenting of properties of arched corrugated steel roof identical radian measure.
A kind of method that improves properties of arched corrugated steel roof use span, comprise design, making, properties of arched corrugated steel roof and cylinder are installed, wherein, upper inner leg place at described cylinder is provided with floor stringer, the top of floor stringer is provided with the vertical auxiliary support of roof system, vertically auxiliary support is supported on properties of arched corrugated steel roof bottom, and the strong point is apart from the cylinder certain distance.
Described method, wherein, described floor stringer comprise the straight line cant beam, with the arc beam of encorbelmenting of properties of arched corrugated steel roof identical radian measure.
Described method, wherein, described floor stringer is divided by material and is comprised concrete beam, girder steel.
The technique effect that the present invention produces is: be provided with at properties of arched corrugated steel roof arch springing side supports place the straight line cant beam or with the arc beam of encorbelmenting of properties of arched corrugated steel roof identical radian measure, cant beam or arc back end are set up the vertical auxiliary support of properties of arched corrugated steel roof, thereby reduce the Practical Calculation span of properties of arched corrugated steel roof, effectively increased the actual use span of properties of arched corrugated steel roof.
Description of drawings
Fig. 1 is the properties of arched corrugated steel room structural representation of the raising use span of straight line cant beam for floor stringer of the present invention;
Fig. 2 is that the properties of arched corrugated steel room structural representation of span is used in the encorbelment raising of arc beam for floor stringer of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, illustrate that design scheme of the present invention and structural principle are as follows:
As shown in Figure 1, improve the properties of arched corrugated steel roof of using span, form by properties of arched corrugated steel roof 1 and cylinder 2, upper inner leg place at cylinder is provided with floor stringer 3, the top of floor stringer 3 is provided with the vertical auxiliary support 4 of roof system, vertically auxiliary support 4 is supported on the bottom of properties of arched corrugated steel roof 1, and the strong point is apart from cylinder 2 certain distances.
Embodiment 1
As shown in Figure 1, the floor stringer that improves the properties of arched corrugated steel roof use span is straight line cant beam, its lower end upper inner leg place at cylinder 2, the top is provided with vertical auxiliary support 4, and vertically auxiliary support 4 is supported on the bottom of properties of arched corrugated steel roof 1, and the strong point is apart from cylinder 2 certain distances.The strong point is apart from the distance of the cylinder use span of the actual increase of properties of arched corrugated steel roof one side just.
As seen from the figure, L1 is for to be controlled at 30M with interior span by the requirement of the rules scope of application;
L2 is the use span of the actual increase of properties of arched corrugated steel roof.
As shown in Figure 2, improve to use span properties of arched corrugated steel roof floor stringer for the arc beam of encorbelmenting of properties of arched corrugated steel roof identical radian measure.Other structure is with embodiment 1.
In sum, the present invention adopts and on properties of arched corrugated steel room cylinder floor stringer is set, the method of vertical supplemental support seat is set on the floor stringer top, reduces the Practical Calculation span of properties of arched corrugated steel roof, effectively increased the actual use span of properties of arched corrugated steel roof.Reached the purpose that the present invention improves the arched corrugated steel roof (acsr) span.
Should be understood that above-mentioned description at specific embodiment is comparatively detailed, can not therefore think the restriction to scope of patent protection of the present invention, scope of patent protection of the present invention should be as the criterion with claims.
