The invention discloses a method for mounting large arched roof panels, belongs to the technical field of large roof panel mounting methods, and is used for mounting arched roof panels of industrial plants with large grid structures and other facilities. One side of a large arched grid structure is provided with a rail and a moving operation platform; an arched panel press is arranged on the moving operation platform; after color steel is pressed and formed by the arched panel press, the roof panels are directly laid onto the arched grid structure, cover the whole roof of the arched grid structure along with the forward movement of the moving operation platform, and are fixed. According to the method, the roof panels can be prevented from generating joints in the horizontal full span of the arched roof, the waste of materials is reduced, and leakage of rain, untight seals and other phenomena at the joints are avoided. The method is scientific and reasonable in design and convenient to implement; the conventional equipment is utilized, a new method having the advantages of convenience for mounting, material saving effect, low labor intensity and high mounting quality is developed for mounting the large arched roof panels, and obvious economic benefit is achieved.

The invention provides a cover fixing structure which can easily carry out cover fixing operation. The cover fixing structure comprises: a cover (3) provided with a foldback part (3c) at the position close to the end, a clamping component (23) arranged at the inner side of the foldback part (3c) of the cover (3), a fastening component (22) which is provided with a groove (22b) which can arrange the clamping component (23) and the foldback part (3c) in a disconnecting prevention state along the length direction, and externally provided with a fixing and clamping part (22a), and a fixing part (10) provided with an installation concave part (20) used for being put in the fastening component (22) along the length direction, and the installation concave part (20) is internally provided with a clamped part (20a); and after the fastening component (22) is inserted into the installation concave part (20) from the direction orthogonal to the length direction of the installation concave part (20), the clamped part (20a) and the clamping part (22a) are clamped with each other. The clamped part (20a) and the clamping part (22a) are clamped with each other by inserting the fastening component (22) into the installation concave part (20) from the direction orthogonal to the length direction of the fixing part (10), and the fastening component (22) is arranged in the installation concave part (20).

The invention discloses a concrete wall surface dry hanging stone structure. The concrete wall surface dry hanging stone structure comprises stone boards, mounting angle steel fixed to a concrete wallsurface, mounting parts and corner connecting parts; the corner connecting parts comprise outer bending strips located outside the stone boards, inner bending strips located in the stone boards, fixed sleeves fixed between the outer bending strips and the inner bending strips and penetrating through the mutually perpendicular stone boards, pressing strips hinged to both sides of the inner bendingstrips, butterfly bolts of which the end parts sequentially penetrate through the outer bending strips and the inner bending strips and pressing plates disposed on the end parts of the butterfly bolts, wherein the butterfly bolts are rotatably connected with the outer bending strips and the inner bending strips separately; the pressing strips are attached to and abut against the side walls, closeto a wall, of the stone boards, the plate surfaces of the pressing plates are horizontal, and the side walls of the two ends of the pressing plates are attached to and abut against the side walls, away from the stone boards, of the pressing strips. The concrete wall surface dry hanging stone structure has the following effects that a novel mechanical structure is utilized, and no special right-angled stone board needs to be manufactured, so that the cost of whole stone is saved.

The invention discloses a dry-hanging stone structure on a concrete wall, which comprises a stone plate, an installation angle steel fixed to the concrete wall, an installation part and a corner connection part; The inner bending strips in the stone slabs, the fixed sleeves fixed between the outer bending strips and the inner bending strips and passing through the mutually perpendicular stone slabs, the hinged joints on both sides of the inner bending strips The compression strips, the butterfly bolts whose ends pass through the outer bending strips and the inner bending strips in turn, and the compression plates arranged on the ends of the butterfly bolts, the butterfly bolts are respectively connected with the outer bending strips and the inner bending strips. The inner bending strips are rotated and connected; the compression strips and the side walls of the stone slabs close to the wall are attached and offset, the surface of the compression slabs is horizontal, and the side walls at both ends of the compression strips are attached to the side walls of the stone slabs away from the stone slabs and press against it. The present invention has the following effects: the scheme utilizes a new mechanical structure, does not need a special right-angled stone plate, and saves the cost of the whole stone.

The invention discloses a housing of a mobile toilet. The housing comprises a top cover, a base and an enclosing wall body, wherein the enclosing wall body comprises two side plates, a rear plate and a door frame, wherein each of edge-bent inner side faces of two sides of the rear plate coats the edge-bent outer side face of one side of each side plate; each edge-bent inner side face and the corresponding edge-bent outer side face are combined by using a fixing plate; each of the edge-bent inner side faces of two sides of the door frame coats the edge-bent outer side face of the other side of each side plate; each edge-bent inner side face and the corresponding edge-bent outer side face are combined by using the fixing plate; all the upper ends of the two side plates and the upper end of the rear plate are bent towards the inside of the toilet and are combined onto the top cover; the upper end of the door frame is bent towards the inside of the toilet, and is inserted and combined onto the top cover; all the lower ends of the two side plates, the lower end of the rear plate and the lower end of the door frame are bent towards the inside of the toilet and are combined onto the base. The housing disclosed by the invention has the beneficial effects that the edge-bent enclosing wall body has no seam, so that rain leakage can be effectively prevented; the strength of the casing can be improved by a plurality of waved ripples on the rear plate and the side plates, and a flanged beam of the top cover; the housing of the mobile toilet is stably fixed by a sling, can resist strong wind and rain, and is particularly suitable for being used in severe environments such as mountain regions and field operation environments.
