Description

Technical Field

[0001] The utility model relates to an arched roof, in particular to an arched steel structure roof, belonging to the technical field of steel structures. Background Art

[0002] In the prior art, a prefabricated arched steel structure roof is disclosed in the utility model with the application number 202222688822.6. In order to solve the problem that when building the main body of an existing steel structure house, bolts need to be used for fixation first to allow workers to release the support of the steel frame, and this process of using bolts for fixation is relatively slow, and workers need to use a lot of physical strength when supporting the steel frame. By connecting the support columns and connectors, the main body of the steel structure can be quickly built, accelerating the construction speed. And by using the method of clamping the fixed steel frame with split-type notches, the labor intensity of building the connecting frame can be reduced, the fixed steel frame can be quickly fixed, and the exhaust blades can exhaust the hot air in the house outside, keeping the environment where the steel structure is located stable and not easily corroded.

[0003] The similar applications currently still have deficiencies:

[0004] The arched beam frame is processed by welding, with a fixed shape. During the process of building and transportation, the shape of the arched beam frame cannot be changed, occupying a large space and being inconvenient for moving and transporting;

[0005] Therefore, an arched steel structure roof is designed to optimize the above problems. Summary of the Utility Model

[0006] The main purpose of the utility model is to provide an arched steel structure roof. The arched beam frame is composed of arc-shaped plates, a first support plate, a second support plate, a support rod, a clamping block, a clamping groove, and a sleeve. The two arc-shaped plates are hinged to each other and hinged to the first support plate, and the first support plate and the second support plate are hinged. The support rod is hinged to the first support plate, and the clamping block on the support rod is inserted into the clamping groove for cooperation. Then, the sleeve limits the connection between the first support plate and the second support plate, enabling the arched beam frame to be folded during transportation and quickly unfolded and assembled during use, making transportation more convenient. By fixing wedge blocks at the ends of the connecting cross beams and providing wedge grooves on the sides of the arc-shaped plates that cooperate with the wedge blocks, the connecting steel beams are connected by a mortise and tenon structure, making installation more convenient and having good stability.

[0021] To make the technical personnel in this technical field more clear and definite about the technical solution of the utility model, the following further describes the utility model in detail in conjunction with the embodiments and the drawings, but the implementation modes of the utility model are not limited thereto.

[0022] As Figures 1 - 4 shown, this embodiment provides an arched steel structure roof, including an arched beam frame 1 and a connecting steel beam 2 connected between two groups of arched beam frames 1. The arched beam frame 1 includes an arc plate 3. There are two groups of arc plates 3 symmetrically arranged, and the ends of the arc plates 3 are hinged to each other. One end of the two arc plates 3 away from the connection part is hinged with a first support plate 4. A second support plate 5 is hinged between the two first support plates 4. A sleeve 9 is sleeved on one end of the first support plate 4 close to the second support plate 5. A support rod 6 is hinged on the top of the first support plate 4. A clamping block 7 is fixed on the top of the support rod 6. Clamping grooves 8 matched with the clamping blocks 7 are arranged on the inner sides of the arc plates 3.

[0023] Overall working principle: If the arched beam frame 1 is large in size and difficult to transport, slide the two sleeves 9 towards the first support plate 4. The sleeve 9 slides out from the outside of the second support plate 5 to release the positioning state of the first support plate 4 and the second support plate 5. Then control the clamping block 7 at the top of the support rod 6 to slide inside the clamping groove 8. After sliding to the top of the clamping groove 8, pull the support rod 6 downwards. At this time, the arc plate 3, the first support plate 4, the second support plate 5 and the support rod 6 are folded to reduce the volume of the arched beam frame 1. When assembling and using, the second support plate 5 supports on the ground, and unfold the two arc plates 3 outwards. During the unfolding process, align the clamping block 7 at the top of the support rod 6 with the top of the clamping groove 8. After the clamping block 7 is completely inserted into the clamping groove 8, control the support rod 6 to turn outwards. The clamping block 7 is stuck inside the clamping groove 8. The first support plate 4 and the second support plate 5 are in a straight line state. Then control the sleeve 9 to slide and cover the connection part of the first support plate 4 and the second support plate 5 to ensure the stable position of the first support plate 4 and the second support plate 5. The assembly of the arched beam frame 1 is completed. Then hoist it to the roof and install the connecting steel beam 2 between the arched beam frames 1.

[0024] In this embodiment, both the first support plate 4 and the second support plate 5 are rectangular steel pipes, and the specifications of the first support plate 4 and the second support plate 5 are the same.

[0025] Local working principle: Ensure that the strength of the first pallet 4 is the same as that of the second pallet 5, and at the same time ensure that the sleeve 9 can fit on the sides of the first pallet 4 and the second pallet 5 simultaneously, with higher stability.

[0026] In this embodiment, the sleeve 9 is a rectangular sleeve, and threaded holes are provided on the outer sides of the sleeve 9.

[0027] Local working principle: During use, in order to improve the stability of the sleeve 9, fixing bolts can be used to pass through the threaded holes for reinforcement.

[0028] In this embodiment, wedges 10 are fixed at the ends of the connecting steel beams 2, and wedge grooves 11 that cooperate with the wedges 10 are provided on the sides of the arc-shaped plates 3.

[0029] Local working principle: When installing the connecting steel beam 2, after lifting the connecting steel beam 2, align the wedge 10 with the wedge groove 11, and then lower the connecting steel beam 2. The wedge 10 is stuck inside the wedge groove 11 to complete the installation of the connecting steel beam 2.

[0030] In this embodiment, there are three groups of wedge grooves 11 on the outer sides of the arc-shaped plates 3, and the distances between adjacent wedge grooves 11 on two arc-shaped plates 3 are the same.

[0031] Local working principle: By providing multiple groups of wedge grooves 11, the number of connecting steel beams 2 between the arched beam frames 1 is increased, improving the strength of the roof.

[0032] The above is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and concept of the present utility model, makes equivalent substitutions or changes, all belong to the protection scope of the present utility model.
