Abstract

The utility model discloses a metal thin wall non-corrugating arch shell. The utility model is composed of a plurality of arch strips, the flanging of which is mutually engaged, wherein, the arch strip is an archy long groove, the side walls of both sides of the long groove are rolled into a shape of a cross section, the upper part of which is thin and the lower part of which is thick, the upper part of the side wall of the long groove is provided with a flanging, and the entire long groove is arc-shaped in the direction of length; a reinforced arch plate can be arranged in the flanging which is mutually engaged between contiguous arch strips. The metal thin wall non-corrugating arch shell of the utility model has the advantages of strong pressure-bearing ability, easy fabrication, material consumption and low cost.

Description

The metal thin-wall non-corrugated arched shell

Technical field

The utility model relates to a kind of building structure, particularly a kind of arch shell structure.

Background technology

Because the special mechanical properties that has of arch shell structure and the characteristic of lighter weight, make the span of arch shell can be very big, architectural in some large-sized workshops, garage etc., use the arch shell usually and make the roof.As shown in Figure 1, present arch shell shuts out many horizontal ripples in order to make arc on the arch bar base plate that constitutes whole arch shell, constitutes arc so that encircle minister bottom weak point on the bar.But this arch bar has a shortcoming, owing to extruding ripple its supporting capacity is reduced along the length direction that encircles bar.In recent years, collapse accident repeatedly appears in this Structural Engineering, and only promptly collapse more than 30 engineering in the whole nation in 2000.

The utility model content

The purpose of this utility model is to provide a kind of metal thin-wall non-corrugated arched shell, and to solve the not enough problem of bearing capacity that above-mentioned ripple arch shell exists, the bearing capacity of the more existing ripple arch of the bearing capacity of this arch shell shell is strong more than 3 times, and steel using amount is few, and cost is low.

In order to achieve the above object, metal thin-wall non-corrugated arched shell of the present utility model has adopted following structure: the metal thin-wall non-corrugated arched shell is made of a plurality of arch bars that are interlocked, its arch bar is an elongated slot, the elongated slot side walls has been rolled into the transverse shape of upper-thin-lower-thick, the side wall upper part of elongated slot has flange, and the length direction of whole elongated slot is an arc.

In order further to increase the integrated carrying ability of arch shell, can increase a reinforcement arch bar every several arch bars in the engaged flange between adjacent arch bar.Arch bar can be than arch bar height to hang objects such as light fixture, light-duty pipeline.

The flange of metal thin-wall non-ripple arch bar side wall upper part overlaps mutually to be interlocked and constitutes the arch shell roof in a large span room layer or factory shop, because the bottom of metal thin-wall non-corrugated arched shell does not have ripple, make its supporting capacity be greatly improved, and owing to there is not ripple not only easy to process, the material usage of the arch shell that also makes reduces, and has reduced cost.By between the arch bar, increasing arch bar, its supporting capacity is further strengthened.

The specific embodiment

Be described further below in conjunction with the arch bar structure of accompanying drawing metal thin-wall non-corrugated arched shell of the present utility model.

As shown in Figure 2, the arch bar of metal thin-wall non-corrugated arched shell of the present utility model is the elongated slot of an arc, does not have transverse wave on the elongated slot.As shown in Figure 3, the sidewall of this metal thin-wall non-ripple arch bar has been rolled into the cross sectional shape of upper-thin-lower-thick, also has flange to the right on top, two side, and the flange bottom on right side also has an inside flanging, so that the mutual interlock of flange of two adjacent arch bars.

Embodiment 1

Metal thin-wall non-corrugated arched shell in the present embodiment is formed by connecting by a plurality of metal thin-wall non-ripple arch bars as shown in Figure 3, and as shown in Figure 4, the flange of adjacent arch bar 1,2 fastens and stings together.

Embodiment 2

In the present embodiment, for further strengthening the supporting capacity of whole metal thin-wall non-corrugated arched shell, as shown in Figure 5, interlock place of encircleing the flange of bars 3,4 at two adjacent metal thin-wall non-ripples also accompanies an arc arch bar 5.

Because the sidewall of arch bar is rolled into the shape of upper-thin-lower-thick, side wall upper part can extend by nature when backing, makes its top elongated, forms arc naturally, and does not need to shut out ripple in the bottom, and easy to process so this arch bar supporting capacity is strong, cost is low.

Claims

1, a kind of metal thin-wall non-corrugated arched shell, be made of a plurality of arch bars that are interlocked, it is characterized in that: its arch bar is an elongated slot, and the elongated slot side walls has been rolled into the transverse shape of upper-thin-lower-thick, the side wall upper part of elongated slot has flange, is arc on the length direction of whole elongated slot.

2, metal thin-wall non-corrugated arched shell as claimed in claim 1 is characterized in that: a reinforcement arch bar that can further improve bearing capacity is arranged in the engaged flange between above-mentioned adjacent arch bar.
