DETAILED DESCRIPTION

[0015] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0016] See also Figure 1-7 The present invention provides a technical solution of an adjustable roof inverted triangle cantilever eaves support structure and a construction method: Embodiment 1: This embodiment provides an adjustable roof inverted triangle eaves support structure according to Figure 1 and Figure 2 As shown, when supporting the inverted triangle eaves of the roof, a bottom lap plate 1 is overlapped at the step on the ground, four columns 2 are vertically fixed on the upper surface of the bottom lap plate 1, a fixed support plate 3 is welded and fixed near the upper end of the column 2, and a supporting mechanism is arranged on the top of the column 2. The supporting mechanism includes an inclined steel pipe 4 hinged to the upper end of the four columns 2, a top support plate 6 parallel to the fixed support plate 3 is arranged above the inclined steel pipe 4, the upper end of the inclined steel pipe 4 is hinged to the bottom of the top support plate 6, and a parallelogram supporting mechanism is formed by the cooperation of the column 2, the fixed support plate 3, the inclined steel pipe 4 and the top support plate 6, and a movable support plate 5 parallel to the fixed support plate 3 is hinged near the lower end of the inclined steel pipe 4. A support assembly is provided above the support mechanism, and support is provided below the inverted triangular eaves of the roof through the support assembly. Due to the mobility of the parallelogram and the lower end of the inclined steel pipe 4 is fixed by the column 2, when the inclination angle of the inclined steel pipe 4 changes, the support assembly can be driven by the inclined steel pipe 4 to adjust the up, down, left and right positions, so that the support mechanism and the support assembly can be adaptively adjusted according to the extended position and extended height of the inverted triangular eaves of the roof, thereby improving the flexibility and versatility of the support.

[0017] The supporting assembly includes a back corrugated board 7 hinged at the inner end above the top support board 6. When supporting the eaves, the back corrugated board 7 contacts the lower wall of the eaves to provide support. A retractable supporting rod 8 is arranged below the back corrugated board 7. The inclination angle of the back corrugated board 7 can be adjusted by the retractable supporting rod 8, thereby providing support for the inverted triangular eaves with different inclination degrees through the back corrugated board 7.

[0018] A support rod 9 is arranged below the parallelogram support mechanism, and the support position of the support mechanism can be fixed by the support rod 9. The support rod 9 includes a support column 92 vertically arranged above the bottom strap 1, a center hole 3a is opened through the center of the fixed support plate 3, a nut 91 is rotatably mounted in the center hole 3a, the upper half of the support column 92 is a threaded section 93, and the threaded section 93 is threadedly mounted in the nut 91, and a horizontal column 94 is vertically welded and fixed at the upper end of the support column 92, and the horizontal column 94 and the support column 92 form a T-shaped structure, and the horizontal column 94 is located between the fixed support plate 3 and the movable support plate 5 and is parallel to them. The movable support plate 5 divides the parallelogram support mechanism into two upper and lower parallelograms, that is, the fixed support plate 3, the movable support plate 5 and part of the inclined steel pipe 4 form a small parallelogram, and the movable support plate 5, the top support plate 6 and part of the inclined steel pipe 4 form a large parallelogram. When the height spacing between the fixed support plate 3 and the movable support plate 5 is fixed, the small parallelogram is fixed, and the large parallelogram is naturally fixed as well. Therefore, when fixing the support mechanism, the nut 91 can be rotated, and the support column 92 and the cross column 94 can be controlled to move upward under the thread cooperation of the nut 91 and the threaded section 93, so that the cross column 94 abuts against the lower surface of the movable support plate 5 to support the movable support plate 5. The height distance between the fixed support plate 3 and the movable support plate 5 is fixed by the cooperation of the support column 92 and the cross column 94, and then the support mechanism is fixed, so that the support mechanism can provide a stable support effect for the eaves.

[0019] A protruding ring 91b is provided at the outer edge of the lower end of the nut 91, and an annular groove matching the protruding ring 91b is provided in the center hole 3a.

A guide groove 96 is longitudinally opened on the side of the threaded section 93, and a guide block 3b is fixed below the fixed support plate 3, and the end of the guide block 3b is clamped in the guide groove 96. When the nut 91 and the threaded section 93 are threadedly matched to control the support column 92 to move up, the cooperation of the guide block 3b and the guide groove 96 provides a guiding effect for the support column 92, so that the support column 92 can be smoothly controlled to move up and down in a directional manner, thereby providing a supporting and fixing function for the movable support plate 5.

[0020] Since the bottom shelving 1 is only placed on the ground steps, the supporting mechanism may tip over when tilting to support the cantilevered eaves. Therefore, a plug-in assembly 95 is provided below the supporting column 9 to limit and fix the bottom shelving 1 and the ground steps together, thereby preventing the supporting mechanism from tipping over. Figure 1 , Figure 5 and Figure 6As shown, a socket 1a is provided at the center of the bottom strap 1 at a position corresponding to the support column 9, and a slot corresponding to the socket 1a is also constructed on the ground step. The lower end of the support column 9 is a hollow structure. The plug-in assembly 95 includes a plug-in column 952 that is longitudinally slidably mounted on the lower end of the support column 9, and the plug-in column 952 is connected to the support column 9 through a spring 951. The upper and lower ends of the spring 951 are respectively fixed to the top of the support column 9 and the upper end of the plug-in column 952. A T-slot 955 is provided on the side wall of the support column 9. A rotating sleeve 953 is rotatably mounted on the upper end of the plug-in column 952. A paddle 954 is fixed on the outer side of the rotating sleeve 953, and the paddle 954 is movably mounted in the T-slot 955. The top transverse groove of the T-slot 955 can limit and fix the paddle 954, at which time the plug post 952 is retracted into the support column 9, and the spring 951 is in a compressed state, which is convenient for adjusting the height of the support column 9; when the plug post 952 needs to be extended, the paddle 954 can be rotated by the rotating sleeve 953, so that the paddle 954 moves to the longitudinal groove of the T-slot 955 to release the limit, and then the plug post 952 is pushed out and inserted into the slot of the insertion hole 1a and the ground step under the elastic force of the spring 951, so that the support mechanism is limited and fixed on the ground step, thereby improving the stability of the support mechanism in supporting the cantilever. And the outer diameter of the plug post 952 matches the inner diameter of the slot of the ground step, so that the plug post 952 does not move after being inserted into the slot.

[0021] Embodiment 2: Based on the first embodiment, the same points as the first embodiment will not be repeated here, and the differences are as follows: Figure 1 and Figure 3 As shown, the retractable support rod 8 is composed of a plurality of screws 81 longitudinally fixed at the bottom of the back corrugated board 7. A flat hole 6a corresponding to the number and position of the screws 81 is opened on the top support board 6. The bottom of the screw 81 is inserted into the flat hole 6a and fixed to the top support board 6 by a nut 82. There are two groups of nuts 82, which are distributed at the upper and lower parts of the top support board 6. The upper nut 82 is pre-installed at the specified position of the screw 81 according to the support angle of the back corrugated board 7. The lower nut 82 is installed and locked at the bottom of the top support board 6 after the back corrugated board 7 supports the eaves. The stability of the support is improved by the upper and lower groups of nuts 82.

[0022] In addition, the supporting height of the retractable supporting rod 8 can be adjusted, and the supporting angle of the back corrugated board 7 can be adjusted by adjusting the height of the retractable supporting rod 8, so that the supporting angle of the back corrugated board 7 can be flexibly adjusted according to the inverted triangular eaves of different shapes or inclinations to provide effective support.

[0023] Embodiment 3: This embodiment provides a construction method for an adjustable roof inverted triangle cantilever eaves support structure: First, a slot matching the size of the plug post 952 is drilled on the ground step, and then the bottom board 1 in the support structure is overlapped on the edge of the ground step, and the plug hole 1a is completely aligned with the position of the plug hole. When placing the support structure, the plug post 952 is retracted in the support column 92, which does not affect the normal placement of the support structure; then the inclination angle of the inclined steel pipe 4 is adjusted to drive the top support plate 6 and the back corrugated board 7 to move, so that the back corrugated board 7 is close to the eaves, and then the position of the nut 82 on the screw rod 81 is adjusted according to the inclination angle of the eaves, and the retractable support rod 8 is used to adjust the position of the nut 82 on the screw rod 81. The inclination angle of the back corrugated board 7 is adjusted to be consistent with the inclination angle of the eaves, so that the back corrugated board 7 is completely fitted with the inclined surface below the eaves, and then the nut 91 is turned to drive the support column 92 to move upward, so that the cross column 94 abuts against the lower surface of the movable support plate 5, and the parallelogram support mechanism is fixed; finally, the paddle 954 is turned to release the limit of the plug column 952, and with the cooperation of the spring 951, the plug column 952 is pushed down and inserted into the slot of the socket 1a and the ground step, thereby reinforcing the overall support structure and providing support for the eaves through the support structure.

[0024] A template can also be placed between the overhanging eaves and the back corrugated board 7. The template is processed according to the shape of the overhanging eaves, and the supporting effect of the overhanging eaves is further improved by the template.
