Embodiment 1

[0034] Example 1, in Figure 1-Figure 9 middle, figure 1 It is a hangar with a rectangular roof, the length of the hall (X direction) is 270 meters, and the width (Y direction) is 240 meters. There are concrete columns 1 on the three surrounding sides, and there are no concrete columns in the middle and right end. There are two rows in the X direction, 31 concrete columns in each row, a total of 30 bays, the first section of the concrete column is 1000×700, and the two sides of the end column and the top section of the rolling bearing are made into short corbels, including corbels 1. The section length of the top of the column is 1200 mm, and the spacing between each span is 9 meters, a total of 270 meters; there is a row in the Y direction, and there are 39 concrete columns in the upper span of the row, with a total of 40 spacings, and the section of the concrete columns is 500×800. Each space is 6 meters, a total of 240 meters; arch trusses 34 are arranged on the two concre...

Embodiment 2

[0035] Example 2, in Figure 10-Figure 15 middle, Figure 10 It is a gymnasium with a circular roof. The diameter of the roof is 240 meters. There are concrete columns 1 around and no concrete columns in the middle. The entire roof is provided with 24 rows of arch trusses 34 (can also be designed as 22 or 18 rows). One end of the lower beam is movable on the concrete column 1, and the other end is fixed on the concrete column. Except that the central structure is different from Embodiment 1, other structures are the same as Embodiment 1. The structure of the upper beam and the lower beam at the center of the roof is: a connecting steel disc is arranged in the middle of the roof, and the connecting steel disc includes an upper round steel disc 22 and a lower round steel disc 23, and tenons are arranged around the upper round steel disc 22 Seat 24, the tenon seat and the upper round steel plate are integral, also can be combined with last round steel plate as a whole, welded i...

Embodiment 3

[0036] Example 3, in Figure 16 and Figure 18 Among them, embodiment 3 is based on embodiment 2. In order to improve the lighting degree, indoor air flow and appearance aesthetics of the circular roof, the circular roof is provided with skylights capable of lighting and mechanical ventilation. The arc slope is higher than the circular roof surface. The skylight roof is composed of glass lighting panels 37 and triangular frames 28. The glass lighting panels are in the shape of a continuous inverted V-shaped folded surface. The triangular frame is located between the glass lighting panels and the circular roof. An exhaust fan 27 is arranged in the skylight, and the glass daylighting panel is generally made of double-layer astigmatism glass (such as embossed glass, frosted glass), and an annular drainage groove 40 is arranged around the circular roof, and the drainage groove is supported on On the ring-shaped concrete beam 39, the edge portion of the roof is formed by inclined ...

Abstract

The invention discloses a large-sized closed roof formed by a light steel truss arch for a building, which comprises truss arch racks (34) of a rectangular roof and truss arch racks (34) of a circular roof. One end of each truss arch rack (34) is movably arranged on a corresponding concrete column (1) while the other end of the truss arch rack (34) is fixedly arranged on the corresponding concrete column (1), each truss arch rack consists of a lower beam (6), an upper beam (2), a suspender (35), an inclined rod (4) and a steel cable (5), a plurality of short rectangular steel bars are connected via steel hinge pins (14) to form each arc-shaped upper beam, a plurality of short rectangular steel clamp plates (8) are connected with bolts (7) to form each lower beam, two ends of each upper beam are fixed on the corresponding lower beam via tongue-and-groove steel wedges (12), one end of each lower beam can freely stretch and retract on the corresponding concrete column via a steel drum (10), the other end of each lower beam is fixed on the corresponding concrete column, and two ends of each inclined rod are movably connected with the corresponding upper beam and the corresponding lower beam. The roof is compact in structure, light in weight, fine in rigidity, high in anti-seismic capacity and structural stability, low in construction cost, convenient in construction and short in construction period, and can meet service requirements of a large-span stadium without struts in the middle, a culture and entertainment center, wharf, a large-sized airplane roof and the like.

Description

Technical field [0001] The invention involves the top of the building, especially the large building closed roof made of light steel arch trustees. Background technique [0002] At present, in the construction engineering, most small and medium -sized construction engineering roofs that have no pillars in the middle and span within 100 meters adopt the steel structure, grid structure, and suspension structure of rigid material rods as a closed roof structure.For large -scale construction engineering roofs with no pillars in the middle (such as gymnasium, cultural and entertainment center, port terminal, large aircraft manufacturing and parking land, etc.), if the above -mentioned small and medium -sized construction engineering roof structure is still adopted, it will be adopted.It will bring the following problems: First, as the size of the main component and the cross section of the rods must be increased as the span distance increases, and the weight of the rod itself increase...
