Technical Field

[0001] The present invention relates to the technical field of concrete construction, and particularly to an auxiliary device and construction method for concrete pouring construction of a large-slope inclined roof. Background Art

[0002] An inclined roof, also known as a pitched roof, refers to a roof with a certain inclination angle or a roof with a certain inclination angle on both sides of a flat roof. It is a common roof form in architectural design. One of the greatest advantages of the roof is its excellent natural drainage ability. The slope helps rainwater flow down quickly, reducing the risk of water accumulation and leakage, and is beneficial to protecting the building structure from water damage. The inclined roof is basically constructed by concrete pouring construction.

[0003] When the existing inclined roof is under concrete pouring construction, first, formwork is laid on the inclined roof according to the design requirements, then steel bars are tied and concrete is filled. After the concrete filling is completed, construction workers use a concrete vibrator to vibrate each area on the slope to vibrate out the air bubbles and air in the concrete, improving the quality of the concrete after solidification. However, when the existing construction workers vibrate the concrete on the inclined roof, they stand on the slope to perform the concrete process, which has the risk of slipping and falling, and to a certain extent reduces the safety of the concrete pouring construction of the large-slope inclined roof.

[0004] Therefore, it is necessary to provide a new auxiliary device and construction method for concrete pouring construction of a large-slope inclined roof to solve the above technical problems. Summary of the Invention

[0013] Preferably, threads are formed inside the support cylinder. A threaded column threadedly connected to the support cylinder is arranged inside the support cylinder. One side of the threaded column extends out of the inside of the support cylinder. A square block is fixedly arranged on the side of the threaded column away from the support cylinder. A support frame is arranged on the side of the square block away from the threaded column. A square groove is formed on the side of the support frame close to the square block.

[0014] A construction method for concrete pouring on a large-slope inclined roof, applicable to the above-mentioned construction auxiliary device for concrete pouring on a large-slope inclined roof, is characterized in that it specifically includes the following steps:

[0015] Step 1, safety measures: Build a construction access road, platform frame and safety protection facilities on the inclined roof to ensure the safety of construction personnel and material transportation;

[0016] Step 2, formwork laying: Construction personnel install the formwork on the inclined roof according to the design drawings, and establish diagonal braces and tie rods to prevent the formwork from deforming or displacing;

[0017] Step 3, support embedding: Construction personnel tie the roof reinforcement according to the design drawings to ensure the correct position, spacing and anchorage length of the reinforcement, and install embedded parts such as drain pipe reserved openings and support fixing points;

[0018] Step 4, concrete pouring: Start from the low place and pour concrete on the inclined roof towards the high place to reduce the sliding of concrete and the lateral pressure on the formwork

[0019] Step 5, equipment laying: Construction personnel place the support frame on the inclined roof, and use the platform frame at the edge of the inclined roof to support and limit the support frame. Install the telescopic mechanism between the two support frames. At the same time, construction personnel insert the concrete vibrator into the connecting cylinder;

[0020] Step 6, vibration positioning: Construction personnel apply a thrust to the power column, so that the power column drives the cylinder to move, so that the cylinder drives the threaded column to move through the support cylinder. The threaded column drives the square block to move inside the square groove of the support frame. When moving to the position on the inclined roof that needs to be vibrated, construction personnel rotate the power column;

[0021] Step 7, equipment limiting: Construction personnel rotate the power column, so that the power column drives the transmission bevel gear to move, the transmission bevel gear drives the meshing moving bevel gear to rotate, so that the moving bevel gear drives the meshing connecting bevel gear to rotate, so that the connecting bevel gear drives the support cylinder to rotate, and the support cylinder drives the threaded column connected to it by thread to extend, and at the same time makes the threaded column drive the square block to extend, and drives the square block into the limiting groove of the support frame to complete the limiting of the square block and complete the limiting of the cylinder at the same time;

[0022] Step 8, concrete vibration: When construction personnel drive the moving bevel gear to rotate, the moving bevel gear drives the connecting cylinder connected to it by thread to move downward, so that the connecting cylinder drives the concrete vibrator to move downward together, drives the concrete vibrator into the concrete on the inclined roof, and at the same time the connecting cylinder drives two arc blocks to move relatively through the conical ring to complete the clamping and limiting of the concrete vibrator and improve the stability of the concrete vibrator in the concrete on the inclined roof;

[0023] Step Nine, equipment reset. After the concrete in this area is vibrated, the construction worker rotates the power column in the reverse direction, so that the power column drives the movable bevel gear to rotate through the transmission bevel gear, and the movable bevel gear drives the connecting cylinder threadedly connected thereto to move upward, so that the connecting cylinder drives the concrete vibrator to move upward together, driving the concrete vibrator out of the concrete in this area of the inclined roof. When driving the concrete vibrator out of the concrete in this area of the inclined roof, the movable bevel gear drives the connecting bevel gear engaged with it to rotate, so that the transmission bevel gear drives the threaded column to retract through the support cylinder, and the threaded column drives the square block to retract, driving the square block out of the limit groove inside the support frame, releasing the limit on the square block and the cylinder. The construction worker continues to perform vibration positioning until the vibration of all areas of the concrete on the inclined roof is completed;

[0024] Step Ten, concrete curing. The construction worker covers a layer of transparent plastic film on the concrete on the inclined roof to reduce the evaporation of water by the barrier effect of the film, and sprays water on it at intervals to ensure the moisture of the concrete.

[0025] Compared with the related technology, the large-slope inclined roof concrete pouring construction auxiliary device and construction method provided by the present invention have the following beneficial effects:

[0026] 1. By driving the power assembly to rotate, the power assembly drives the movable bevel gear engaged with it to rotate. The movable bevel gear drives the connecting cylinder threadedly connected thereto to move downward, so that the connecting cylinder drives the concrete vibrator to move downward together, driving the concrete vibrator into the concrete in this area of the inclined roof, and the vibration process of the concrete in this area of the inclined roof can be carried out. Through this structure, the construction worker can vibrate the concrete at a long distance on the large-slope inclined roof without standing on the slope of the inclined roof for vibration operation, greatly reducing the risk of slipping and falling, and improving the safety of the large-slope inclined roof concrete pouring construction to a certain extent.

[0027] 2. The power assembly drives the movable bevel gear engaged with it to rotate. The movable bevel gear drives the connecting cylinder threadedly connected thereto to move downward, so that the connecting cylinder drives the concrete vibrator to move downward. At the same time, the connecting cylinder drives two arc blocks to move relatively through the conical ring, completing the clamping and limiting of the concrete vibrator, realizing the precise clamping and limiting of the concrete vibrator, ensuring the stability and uniformity of the vibration process, thereby improving the quality of concrete pouring and reducing the occurrence of quality problems such as cavities and cracks.

[0028] 3. In the present invention, the construction worker rotates the power column, causing the power column to drive the transmission bevel gear to move. The transmission bevel gear drives the movable bevel gear engaged therewith to rotate. The movable bevel gear drives the connecting bevel gear engaged therewith to rotate, causing the connecting bevel gear to drive the support cylinder to rotate. The support cylinder drives the threaded column threadedly connected thereto to extend, and at the same time, the threaded column drives the square block to extend, driving the square block into the limiting groove of the support frame to complete the limitation of the square block and simultaneously complete the limitation of the cylinder. Through this structure, the limitation of the cylinder can be quickly completed, facilitating the construction worker to quickly carry out the vibration of the concrete on the inclined roof, and improving the construction efficiency of the concrete pouring on the large-slope inclined roof to a certain extent.

[0029] 4. In the present invention, the construction worker rotates the power column, causing the power column to drive the transmission bevel gear to move. The transmission bevel gear drives the movable bevel gear engaged therewith to rotate. When the movable bevel gear drives the square block to extend through the connecting bevel gear and completes the limitation of the cylinder, the movable bevel gear drives the connecting cylinder threadedly connected thereto to move downward, causing the connecting cylinder to drive the concrete vibrator to move downward together. Through this structure, the stable limitation of the equipment and the extension work of the equipment are carried out simultaneously, reducing the preparation work of the equipment construction and further improving the construction efficiency of the construction worker.

The outer surface of the connecting cylinder 4 is rotationally connected to the inner surface of the cylinder 2. A conical ring 5 is fixedly arranged at the bottom of the connecting cylinder 4. Two arc - shaped blocks 6 are movably arranged at the bottom of the conical ring 5. The outer surfaces of the two arc - shaped blocks 6 are slidably connected to the inner surface of the conical ring 5.

[0051] The outer surface edges of the top ends of the two arc blocks 6 are chamfered to facilitate the conical ring 5 to drive the two arc blocks 6 to move relative to each other. The top ends of the two arc blocks 6 on one side are chamfered to facilitate the concrete vibrator 1 to pass through the two arc blocks 6. The support ring 10 limits the movable bevel gear 3 through the support groove 9 to prevent the movable bevel gear 3 from separating from the cylinder 2 and avoid equipment abnormalities. When the connecting cylinder 4 drives the blocking ring 11 to move upward, the blocking ring 11 releases the limit on the two arc blocks 6 and simultaneously releases the clamping limit of the two arc blocks 6 on the concrete vibrator 1.

[0052] The supporting mechanism includes a connecting bevel gear 12, which is arranged inside the cylinder 2, and the bottom of the connecting bevel gear 12 is meshed with one side of the top of the movable bevel gear 3. A supporting cylinder 13 is fixedly provided on one side of the connecting bevel gear 12, and the supporting cylinder 13 is movably extended out of the cylinder 2 away from one side of the connecting bevel gear 12.

[0054] Such as Figure 16 , a construction method for pouring concrete on a large-slope inclined roof, which is applicable to the above-mentioned construction auxiliary device for pouring concrete on a large-slope inclined roof, and specifically includes the following steps:

[0055] Step 1, safety measures. Build a construction access road, platform frame and safety protection facilities on the inclined roof to ensure the safety of construction personnel and material transportation;

[0056] Step 2, formwork laying. Construction workers install the formwork on the inclined roof according to the design drawings, and establish inclined struts and tie rods to prevent the formwork from deforming or displacing;

[0057] Step 3, support embedding. Construction workers tie the roof reinforcement according to the design drawings to ensure the correct position, spacing and anchorage length of the reinforcement, and install embedded parts such as drain pipe reserved openings and support fixing points;

[0058] Step 4, concrete pouring. Start pouring concrete on the inclined roof from the low place to the high place to reduce the concrete sliding and formwork side pressure

[0059] Step 5, equipment laying. Construction workers place the support frame 16 on the inclined roof, and the platform frame at the edge of the inclined roof supports and limits the support frame 16. Install the telescopic mechanism between the two support frames 16. At the same time, construction workers insert the concrete vibrator 1 into the connecting cylinder 4;

[0060] Step 6, vibration positioning. Construction workers apply a thrust to the power column 8 to drive the cylinder 2 to move. The cylinder 2 drives the threaded post 14 to move through the support cylinder 13. The threaded post 14 drives the square block 15 to move inside the square groove 18 of the support frame 16. When moving to the position on the inclined roof that needs to be vibrated, construction workers rotate the power column 8;

[0061] Step 7, equipment limiting: The construction worker rotates the power column 8, causing the power column 8 to drive the transmission bevel gear 7 to move. The transmission bevel gear 7 drives the moving bevel gear 3 engaged with it to rotate. The moving bevel gear 3 drives the connecting bevel gear 12 engaged with it to rotate. The connecting bevel gear 12 drives the support cylinder 13 to rotate. The support cylinder 13 drives the threaded column 14 threadedly connected to it to extend. At the same time, the threaded column 14 drives the square block 15 to extend, driving the square block 15 into the limiting groove 17 of the support frame 16, completing the limiting of the square block 15 and simultaneously completing the limiting of the cylinder 2.

[0062] Through this structure, the limiting of the cylinder 22 can be quickly completed, facilitating the construction worker to quickly carry out the vibration of the concrete on the inclined roof, improving the construction efficiency of the concrete pouring on the large-slope inclined roof to a certain extent, and ensuring the pertinence and effectiveness of the vibration operation.

[0063] Step 8, concrete vibration: When the construction worker drives the moving bevel gear 3 to rotate, the moving bevel gear 3 drives the connecting cylinder 4 threadedly connected to it to move downward. The connecting cylinder 4 drives the concrete vibrator 1 to move downward together, driving the concrete vibrator 1 into the concrete on the inclined roof. At the same time, the connecting cylinder 4 drives two arc-shaped blocks 6 to move relative to each other through the conical ring 5, completing the clamping and limiting of the concrete vibrator 1, and improving the stability of the concrete vibrator 1 in the concrete on the inclined roof.

[0064] The connecting cylinder 4 drives two arc-shaped blocks 6 to move relative to each other through the conical ring 5, completing the clamping and limiting of the concrete vibrator 1, achieving the precise clamping and limiting of the concrete vibrator 1, ensuring the stability and uniformity of the vibration process, effectively improving the stability during the vibration process and the density of the concrete, reducing the voids and bubbles inside the concrete, and enhancing the strength and durability of the structure.

[0065] Step 9, equipment reset: After the concrete in this area is vibrated, the construction worker rotates the power column 8 in the reverse direction, causing the power column 8 to drive the moving bevel gear 3 to rotate through the transmission bevel gear 7. The moving bevel gear 3 drives the connecting cylinder 4 threadedly connected to it to move upward. The connecting cylinder 4 drives the concrete vibrator 1 to move upward together, driving the concrete vibrator 1 out of the concrete in this area of the inclined roof. When driving the concrete vibrator 1 out of the concrete in this area of the inclined roof, the moving bevel gear 3 drives the connecting bevel gear 12 engaged with it to rotate. The transmission bevel gear 7 drives the threaded column 14 to retract through the support cylinder 13. The threaded column 14 drives the square block 15 to retract, driving the square block 15 out of the limiting groove 17 of the support frame 16, releasing the limiting of the square block 15 and the cylinder 2. The construction worker continues to perform vibration positioning until all areas of the concrete on the inclined roof are vibrated.

[0066] Step Ten: Concrete curing. Construction workers cover a layer of transparent plastic film on the concrete on the sloping roof to reduce water evaporation by the barrier effect of the film, and spray water on it at intervals to ensure the moisture of the concrete.

[0067] The circuits and controls involved in the present invention are all prior arts and will not be elaborated here too much.

[0068] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention.

A construction method for concrete pouring of a large-slope inclined roof, applicable to the construction auxiliary device for concrete pouring of a large-slope inclined roof according to any one of claims 1-7, characterized in that, Specifically, it includes the following steps: Step 1, safety measures. Build a construction access road, platform frame and safety protection facilities on the inclined roof to ensure the safety of construction personnel and material transportation; Step 2, formwork laying. Construction personnel install the formwork on the inclined roof according to the design drawings, and establish diagonal braces and tie rods to prevent the formwork from deforming or shifting; Step 3, support embedding. Construction personnel tie the roof steel bars according to the design drawings to ensure the correct position, spacing and anchorage length of the steel bars, and install embedded parts such as drain pipe reserved openings and support fixing points; Step 4, concrete pouring. Start from the low place and pour concrete on the inclined roof towards the high place to reduce the sliding of the concrete and the lateral pressure on the formwork; Step 5, equipment laying. Construction personnel place the support frame (16) on the inclined roof, and use the platform frame and formwork at the edge of the inclined roof to support and limit the support frame (16). Install the telescopic mechanism between the two support frames (16). At the same time, construction personnel insert the concrete vibrator (1) into the inside of the connecting cylinder (4); Step 6, vibration and positioning. Construction personnel apply a thrust to the power column (8) to drive the cylinder (2) to move by the power column (8), so that the cylinder (2) drives the threaded column (14) to move through the support cylinder (13). The threaded column (14) drives the square block (15) to move inside the square groove (18) of the support frame (16) by driving the square block (15). When moving to the position on the inclined roof that needs to be vibrated, construction personnel rotate the power column (8); Step 7, equipment limitation. Construction personnel rotate the power column (8) to drive the transmission bevel gear (7) to move by the power column (8). The transmission bevel gear (7) drives the movable bevel gear (3) engaged therewith to rotate. The movable bevel gear (3) drives the connecting bevel gear (12) engaged therewith to rotate. The connecting bevel gear (12) drives the support cylinder (13) to rotate. The support cylinder (13) drives the threaded column (14) threadedly connected thereto to extend. At the same time, the threaded column (14) drives the square block (15) to extend, and drives the square block (15) to enter the inside of the limiting groove (17) of the support frame (16) to complete the limitation of the square block (15), and at the same time complete the limitation of the cylinder (2); Step eight, concrete vibration. When the construction worker drives the movable bevel gear (3) to rotate, the movable bevel gear (3) drives the connecting cylinder (4) threadedly connected thereto to move downward, so that the connecting cylinder (4) drives the concrete vibrator (1) to move downward together, driving the concrete vibrator (1) into the concrete of the inclined roof. At the same time, the connecting cylinder (4) drives two arc-shaped blocks (6) to move relative to each other through the conical ring (5), completing the clamping and limiting of the concrete vibrator (1), and improving the stability of the concrete vibrator (1) in the inclined roof concrete; Step nine, equipment reset. After the concrete in this area is vibrated, the construction worker rotates the power column (8) in the reverse direction, so that the power column (8) drives the connecting cylinder (4) to move upward through the transmission bevel gear (7), so that the connecting cylinder (4) drives the concrete vibrator (1) to move upward together, driving the concrete vibrator (1) out of the concrete in this area of the inclined roof. When driving the concrete vibrator (1) out of the concrete in this area of the inclined roof, the movable bevel gear (3) drives the connecting bevel gear (12) meshing with it to rotate, so that the transmission bevel gear (7) drives the square block (15) to retract, driving the square block (15) out of the limiting groove (17) inside the support frame (16), releasing the limit on the square block (15) and the cylinder (2). The construction worker continues to perform vibration positioning until all areas of the concrete on the inclined roof are vibrated; Step ten, concrete curing. The construction worker covers a layer of transparent plastic film on the concrete on the inclined roof on the concrete surface, uses the barrier effect of the film to reduce water evaporation, and sprays water on it at intervals to ensure the moisture of the concrete.
