[0002] Slope roof structures are widely used in construction projects. The eaves structures of slope roofs are mostly inclined cantilever structures that extend beyond the exterior wall of the structure. Their formwork support systems must be separately set on the exterior wall of the structure, and generally have a relatively high erection height and a large reinforcement difficulty, which are extremely likely to form potential safety hazards. When constructing a cantilevered arc-shaped slope roof, a support device is required to support it to ensure safety during construction.

[0003] The patent with the patent application number CN217461472U discloses a support device for the eaves of a cantilevered slope roof, which consists of a support device body. The support device body includes a support mechanism, a fixing mechanism, and a supporting mechanism; the support mechanism is composed of split triangular units, and each triangular unit includes a first framework and a second framework; each first framework and second framework are respectively composed of a cross beam, a vertical beam, and an inclined beam; the fixing mechanism is composed of a mountain-shaped clamp, a tie rod, and a backing plate; the supporting mechanism is composed of a clamping bracket, an adjustable support, and a screw plate; wherein: one end of the fixing mechanism is respectively connected to the vertical beams in the first framework and the second framework through the mountain-shaped clamp, and the other end is connected to the slope roof through the backing plate; the cross beams of the first framework and the second framework are respectively connected to the adjustable supports of the supporting mechanism through the screw plate;

[0035] 1. When the present invention is in use, the whole device can be installed at the construction site or in the factory.

[0069] The external thread cylinder 305 is arranged at the bottom of the chuck plate 304. The external thread cylinder 305 is sleeved on the surface of the central top cylinder frame 3. The strengthening support cylinder frame 1 is threadedly connected with the external thread cylinder 305, and the external thread cylinder 305 is movably connected with the central top cylinder frame 3;

[0070] The connecting shaft seat 306 is arranged on the top of the chuck plate 304. The bottom of the connecting shaft seat 306 penetrates through the chuck plate 304 and extends into the central top cylinder frame 3, and the connecting shaft seat 306 is clamped with the chuck plate 304;

[0071] The rotating shaft 307, the connecting shaft seat 306 is arranged on the top of the rotating shaft 307. The rotating shaft 307 is fixedly connected with the connecting shaft seat 306, and the top of the rotating shaft 307 penetrates through the first strengthening shaft pin seat 201 and extends to the top of the first strengthening shaft pin seat 201;

[0072] The abutting plate 308 is arranged at the bottom of the second strengthening shaft pin seat 202;

[0073] The supporting rod 309 is arranged on the top of the abutting plate 308. One end of the supporting rod 309 penetrates through the second strengthening shaft pin seat 202 and extends to the bottom of the positioning card plus 302 to contact with the positioning tooth 303.

[0074] A plurality of cross beam top rods 4 are arranged on the side surface of the supporting column 206 and the adjusting plate frame 205. A cushion block 401 is arranged at one end of each cross beam top rod 4, and a cross beam groove 402 for limiting the cross beam is formed on the cushion block 401.

[0075] When the above structure is in use, when the present invention is in use and supports a cantilevered arc-shaped slope roof, a support device adapted to the project size is manufactured according to the actual needs of the project. During use, the staff can rotate the rotating shaft 307. Since the rotating shaft 307 is on the connecting shaft seat 306, and one end of the connecting shaft seat 306 penetrates through the chuck plate 304, the connecting shaft seat 306 can be firmly connected to the chuck plate 304. Then, when the rotating shaft 307 rotates, it will drive the chuck plate 304 and the external thread cylinder 305 to rotate. When the external thread cylinder 305 rotates, since the external thread cylinder 305 is threadedly connected to the reinforced support cylinder frame 1, the reinforced support cylinder frame 1 will be displaced due to the torque when the external thread cylinder 305 rotates. Then, the first reinforced shaft pin seat 201 will be displaced due to the traction force when the reinforced support cylinder frame 1 is displaced, so that the distance between the first reinforced shaft pin seat 201 and the second reinforced shaft pin seat 202 can be changed. Then, the distance between the first support cross plate 203 on the first reinforced shaft pin seat 201 and the second support cross plate 204 on the second reinforced shaft pin seat 202 can be adjusted;

[0076] When the first reinforced shaft pin seat 201 and the second reinforced shaft pin seat 202 are displaced, they will drive the adjusting plate frame 205 to be displaced. Since the adjusting plate frame 205 is movably connected to the first reinforced shaft pin seat 201 and the second reinforced shaft pin seat 202 respectively, when the first reinforced shaft pin seat 201 and the second reinforced shaft pin seat 202 are displaced, they will drive the adjusting plate frame 205 to be displaced first. And the adjusting plate frame 205 is movably connected to the support column 206 through the support shaft hole block 212 and the adjusting plate frame 205. Through the sliding groove 207, when the first reinforced shaft pin seat 201 and the second reinforced shaft pin seat 202 are displaced, the adjusting plate frame 205 can rotate along the center point of the connection between the adjusting plate frame 205 and the first reinforced shaft pin seat 201 and the second reinforced shaft pin seat 202 under the limit of the support positioning shaft 208, so that the adjusting plate frame 205 can be unfolded on the first support cross plate 203 and the second support cross plate 204;

[0077] After the adjusting plate frame 205 is flipped, the support column 206 and the cross beam top rod 4 on the adjusting plate frame 205 can be on the same horizontal plane. The steel beam is limited through the cross beam groove 402. During use, the staff can make appropriate adjustments according to the actual on-site situation;

[0078] And the whole device can also be installed at the construction site or in the factory. During installation, the reinforced support cylinder frame 1 and the central top cylinder frame 3 are limited by the positioning card plus 302. When the top support rod 309 is inserted into the positioning card plus 302, the multiple positioning teeth 303 will be affected by the top support rod 309 When the top support rod 309 is extended, it will spread to the outside of the top support rod 309 at the same time, and then the positioning teeth 303 can be clamped together with the limiting groove 301. Due to the positioning of the positioning teeth 303 by the limiting groove 301 and the top support rod 309 When the top support rod 309 is inserted, the various structures can be connected together, which is convenient for the staff to install it;

[0079] And when the adjusting plate frame 205 is flipped, the interference between the adjusting plate frame 205 and the first supporting cross plate 203 and the second supporting cross plate 204 is staggered through the transition groove 209, and the adjusting plate frame 205 is limited by the inner wall of the transition groove 209, which can effectively ensure the stability of the adjusting plate frame 205 when supporting the beam later.

[0080] See attached Figure 6 As shown, a plurality of boosting blocks 5 are disposed at the bottom of the adjusting plate frame 205, and the boosting blocks 5 are in contact with the inner wall of the transition groove 209 and are slidably connected with the transition groove 209;

[0081] It should be added that, by providing the boost block 5 , the friction between the adjusting plate frame 205 and the transition groove 209 can be increased, providing a certain resistance when the adjusting plate frame 205 is turned over, and playing a role in positioning the adjusting plate frame 205 .
