Abstract
The utility model discloses an arched corrugated steel roof with increased service span, which is characterized in that linear oblique beams are disposed on the inner sides of the upper portions of columns, or overhang arc beams are disposed on the tops of the columns, auxiliary longitudinal roof supports are disposed at the top ends of the linear oblique beams or the overhang arc beams, the auxiliary longitudinal roof supports are supported on the lower side of the arched corrugated steel roof, and certain distances are reserved from support points to the columns. The linear oblique beams or the overhang arc beams are auxiliary beams. The arched corrugated steel roof adopts the method of disposing the auxiliary beams on the columns below the arched corrugated steel roof and disposing the auxiliary longitudinal supports at the top ends of the auxiliary beams, so that actual calculation span of the arched corrugated steel roof is reduced, and actual service span of the arched corrugated steel roof is effectively increased.
Description
Technical field
The utility model relates to a kind of building, relates in particular to a kind of properties of arched corrugated steel roof of using span that improves.
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 the properties of arched corrugated steel building, a lot of occasions often need the restriction of the span of properties of arched corrugated steel building greater than 30M, produce contradiction between the demand in market and the prior art.
Thereby prior art awaits to improve and improve.
The utility model content
The purpose of this utility model is to provide a kind of magnificence of large span, the properties of arched corrugated steel roof that can improve existing use span of safety.
The technical solution of the utility model comprises:
A kind of properties of arched corrugated steel roof of using span that improves, comprise properties of arched corrugated steel roof, cylinder, wherein, the upper inner of described cylinder is provided with floor stringer, the top of floor stringer is provided with the vertical auxiliary support of roof system, the vertical auxiliary support of roof system is supported on arched corrugated steel roof (acsr) 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.
The technique effect that the utility model 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, the vertical auxiliary support of properties of arched corrugated steel roof is set up in cant beam or arc beam upper end, 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 raising use span properties of arched corrugated steel room structural representation of straight line cant beam for the utility model floor stringer;
Fig. 2 is that span properties of arched corrugated steel room structural representation is used in the encorbelment raising of arc beam for the utility model floor stringer.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, illustrate that structural principle of the present utility model is as follows:
As shown in Figure 1, a kind of properties of arched corrugated steel roof of using span that improves, 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 upper end 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 of using span can be selected steel concrete or steel work for use as straight line cant beam, material.The lower end of straight line cant beam is at the upper inner leg place of cylinder 2, and the upper end 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, the floor stringer that improves the properties of arched corrugated steel roof of using span is and the arc beam of encorbelmenting of properties of arched corrugated steel roof identical radian measure that material can be selected steel concrete or steel work for use.Other structure is with embodiment 1.
In sum, the utility model adopts and on the cylinder of bottom, properties of arched corrugated steel room floor stringer is set, the method of vertical auxiliary support 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.Having reached the utility model provides a kind of magnificence of large span, the raising of safety to use the purpose of the properties of arched corrugated steel roof of span.
Should be understood that above-mentioned description at specific embodiment is comparatively detailed, can not therefore think the restriction to the utility model scope of patent protection, scope of patent protection of the present utility model should be as the criterion with claims.
Claims (2)
1. one kind is improved the properties of arched corrugated steel roof of using span, comprise properties of arched corrugated steel roof, cylinder, it is characterized in that: the upper inner of described cylinder is provided with floor stringer, the top of floor stringer is provided with the vertical auxiliary support of roof system, and the vertical auxiliary support of roof system is supported on arched corrugated steel roof (acsr) bottom.
2. the properties of arched corrugated steel roof of span is used in raising according to claim 1, it is characterized in that: 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.
