Description

Technical Field

[0001] The invention relates to the field of limiting connection devices, in particular to a roof corrugated steel plate connection structure. Background Art

[0002] The coated or plated plate is rolled and cold-bent to form a wavy cross-section along the width of the plate. It is called a corrugated steel plate, which is generally used for laying the roof of a house.

[0003] When laying the corrugated steel sheets on the bracket on the roof, the adjacent corrugated steel sheets need to be connected. Otherwise, directly placing the corrugated steel sheets will easily lead to the misalignment of adjacent corrugated steel sheets. Therefore, the corrugated steel sheets need to be limited to facilitate the placement of adjacent corrugated steel sheets. The existing connection device can only fix specific corrugated steel sheets and is not convenient for connecting corrugated steel sheets with different inclined surfaces. Therefore, a roof corrugated steel sheet connection structure is needed to adjust the connection structure to adapt to more corrugated steel sheets. Summary of the invention

[0004] The purpose of the present invention is to provide a roof corrugated steel plate connection structure to overcome the defect that the existing connection structure is inconvenient to adjust and thus the connection structure cannot limit more types of corrugated steel plates.

[0005] The technical solution to achieve the above-mentioned purpose is: a roof corrugated steel plate connection structure, including a steel plate main body, a slot is provided on one end side wall of the steel plate main body, a clamping groove is provided on one end side wall of the slot, a plurality of first screw holes are also provided on one end of the steel plate main body, a connecting plate is connected to the other end side wall of the steel plate main body, a through hole is provided on the side wall of the connecting plate, a clamping plate is connected to the side wall of one end of the connecting plate, a screw is threadedly connected to the side wall of the first screw hole, an adjustment mechanism is provided on the side walls of two adjacent steel plate main bodies, a limiting mechanism is installed on the adjustment mechanism, and an auxiliary mechanism is installed on the adjustment mechanism.

[0006] Preferably, the adjustment mechanism includes a support plate, a guide rod, a top block, a top hole, a support screw and an adjusting nut, two symmetrically distributed guide rods are connected to both ends of the side wall of the support plate, the top end of the support plate is connected to the top block, the side wall of the top block is provided with a top hole, the center of the side wall of the support plate is connected to the support screw, and the side wall of the support screw is threadedly connected to two groups of symmetrically distributed adjusting nuts.

[0007] Preferably, the support screws and guide rods are symmetrically distributed about the symmetry axis of the support plate.

[0008] Preferably, the limiting mechanism includes a slide plate, a sliding hole, a rotating shaft, a pressure plate, a limiting screw and a second screw hole. Three sliding holes distributed in an array are opened at the upper end of the side wall of the slide plate. The side walls of the sliding holes on both sides are slidably inserted and connected to the guide rod, and the side wall of the remaining sliding hole is slidably inserted and connected to the supporting screw. The bottom end of the side wall of the slide plate is rotatably connected to the rotating shaft, and the side wall of the rotating shaft is connected to the pressure plate. The bottom end of the side wall of the slide plate is also provided with two symmetrically distributed second screw holes, and the limiting screws are threadedly connected to the second screw holes.

[0009] Preferably, the slide plate is in a U-shape and is located between two adjacent adjusting nuts.

[0010] Preferably, the distance between the second screw hole and the rotating shaft is smaller than the thickness of the pressing plate.

[0011] Preferably, the auxiliary mechanism comprises a connecting screw and a limiting nut, a side wall of the connecting screw is threadedly connected with a plurality of limiting nuts, and the side wall of the connecting screw passes through a top hole.

[0012] Preferably, limiting nuts are provided on both sides of each of the top blocks.

[0013] The beneficial effects of the present invention are:

[0014] 1) Align the adjacent steel plate bodies horizontally, insert the adjacent connecting plates into the slots, and pull the connecting plates longitudinally so that the connecting plates drive the card plates to be inserted into the card slots, thereby connecting the two adjacent steel plate bodies as one. At this time, the through holes are also aligned with the first screw holes, and the screws are screwed from the first screw holes into the through holes, thereby fixing the connecting plates and the slots together, and then fixing the adjacent steel plate bodies as one, thereby avoiding the movement and dislocation of the adjacent steel plate bodies.

[0015] 2) Align the three sliding holes with the two guide rods and the support screws respectively, and slide the guide rods and the support screws into the corresponding sliding holes respectively. Push the slide plate to move left and right on the guide rod. The slide plate drives the rotating shaft to move, and the rotating shaft drives the pressure plate to move. Use the adjusting nut to clamp the slide plate, so as to facilitate the fixation of the slide plate, thereby adjusting the distance between the two pressure plates. By rotating the pressure plate, the inclination angle of the pressure plate can be adjusted. By rotating the limit screws, the two limit screws can clamp the pressure plate inward from both sides of the pressure plate, so as to adapt to the surface of the steel plate body with various inclined surfaces.

[0016] 3) Align and stick two longitudinally adjacent steel plate bodies together, and stick the bottom end of the support plate to the high point of the two longitudinally adjacent steel plate bodies. At this time, then, rotate the pressure plate to make the pressure plate parallel to the inclined surface of the steel plate body, and then push the slide plate, the slide plate drives the rotating shaft to move, and the rotating shaft drives the pressure plate to move, so that the pressure plate can be tightly pressed on the inclined surfaces of the two longitudinally adjacent steel plate bodies, and then, clamp the two limiting screws to fix the two sides of the pressure plate, and use the adjusting nut to clamp the slide plate, so as to fix the whole on the two longitudinally adjacent steel plate bodies, thereby avoiding the movement and dislocation of the two longitudinally adjacent steel plate bodies.
