Description

Technical Field

[0001] This invention relates to the technical field of large-scale irregular inclined column assembly and construction equipment, specifically to a bottom grouting explosion-proof chamber device adapted to different large-scale irregular inclined columns. Background Technology

[0002] Grouting explosion-proof chamber refers to a precast column placed on a pre-reserved steel bar at the bottom of an engineering site using mechanical or manual means. Since there is a gap between the precast opening and the steel bar, grouting must be used to seal it. During grouting, the bottom of the precast column cannot be completely sealed to the ground, which can lead to mortar leakage and affect the quality of the project. Therefore, a formwork is made to prevent mortar from flowing out. However, due to gravity and the grouting height, a force will be generated to squeeze the formwork, causing the formwork chamber to burst. Therefore, some processes must be adopted to make the formwork able to withstand the pressure generated during the grouting construction at the bottom of the irregular inclined column.

[0003] Before grouting large, irregularly shaped inclined columns, a formwork seal needs to be made according to the bottom shape of the column. During grouting, care must be taken to prevent the pressure generated during grouting from causing the formwork to twist, deform, or even burst. Because the bottom shape of irregularly shaped inclined columns is not fixed, ordinary explosion-proof chamber methods cannot effectively distribute the force evenly at the bottom of the column, which can lead to quality problems such as grout leakage at some edges. Designing a special explosion-proof chamber device for this type of irregularly shaped inclined column is time-consuming, costly, and cannot be reused, which leads to low construction efficiency and increased costs.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a bottom grouting explosion-proof chamber device that can be adapted to different large-sized irregular-shaped inclined columns, solving the problems of edge grout leakage, long construction time, high cost, and non-reusability in traditional construction techniques for explosion-proof chambers of irregular-shaped inclined columns.

[0006] A bottom grouting explosion-proof chamber device adapted to different large irregularly shaped inclined columns includes an irregularly shaped inclined column, and also includes a pressurizing component, a force-bearing component, a sealing component and a motor drive component; the sealing component, the force-bearing component and the pressurizing component are respectively installed from the inside to the outside along the central axis of the irregularly shaped inclined column;

[0007] The pressurizing assembly includes a threaded screw;

[0008] The motor drive assembly is equipped with a housing, and a pressurizing assembly is installed under the housing. A motor is installed outside the housing, and multiple sets of motors are arranged circumferentially. The motor drive assembly transmits pressure to the force-bearing assembly by driving the threaded screw of the pressurizing assembly to rotate.

[0009] The force-bearing component includes a steel ball; the sealing component includes sheet metal and a sealing rubber ring.

[0010] The force-bearing component transmits pressure to the sheet metal in the sealing component through the internal steel ball. The sheet metal is suitable for evenly transmitting pressure to the sealing rubber ring, which fits against the bottom of the irregularly shaped inclined column.

[0011] The motor drive assembly contains at least eight motors and components. The motor drive assembly transmits pressure to the force-bearing component through the threaded screw of the rotating pressure component. The force-bearing component then transmits the pressure to the sheet metal in the sealing component through the internal steel ball. Due to the rigidity of the sheet metal, the pressure is evenly transmitted to the rubber ring in the sealing component. The rubber ring, due to its fit against the bottom of the irregular inclined column and its own elasticity, achieves a good seal at the gap between the bottom of the irregular inclined column and the ground under the pressure of the sheet metal, thereby achieving a sealing effect.

[0012] In a further technical solution, the outer casing has an irregularly shaped hole in the middle, and the irregularly shaped hole is adapted to the irregularly shaped inclined column;

[0013] The outer casing is provided in pairs and has connecting ears, and connecting bolts are installed on the connecting ears.

[0014] In a further technical solution, the pressurizing component also includes an iron ring, a force-bearing shovel, and a coupling. The iron ring has a threaded hole, and the threaded screw passes through the threaded hole of the iron ring. The force-bearing component also includes an inner iron ring, and the force-bearing shovel at the bottom of the threaded screw is close to the outer wall of the inner iron ring.

[0015] In a further technical solution, the coupling of the pressurizing component connects the threaded screw to the output end of the motor.

[0016] In a further technical solution, the force-bearing component also includes wire knots, which fix multiple steel balls and several wire knots are fixed to the outer wall of the inner iron ring.

[0017] In a further technical solution, the steel balls have a diameter that gradually increases from the inside to the outside. The outermost steel ball is attached to the inner wall of the perforated variable circumference iron ring, and the innermost steel ball is attached to the outer wall of the iron sheet.

[0018] Multiple rows of steel balls are installed inside the inner iron ring. The steel balls in the same row are arranged coaxially and fastened to the iron wire.

[0019] In a further technical solution, the inner side of the sheet metal is tightly fitted with a sealing rubber ring;

[0020] The inner side of the sealing rubber ring is in close contact with the bottom of the irregularly shaped inclined column.

[0021] Beneficial effects:

[0022] As can be seen from the above technical solution, the present invention provides a bottom grouting explosion-proof chamber device adapted to different large irregular inclined columns. In use, the device needs to be placed on both sides of the irregular inclined column first, then the connecting bolts are aligned, and the two devices are moved towards each other and connected by the connecting bolts. Then, according to the circumference and shape of the irregular inclined column, corresponding iron sheets and sealing rubber rings are made. Then, steel balls are placed according to the space between the force-bearing components and the irregular inclined column. After the steel balls are filled, the steel balls are tightened by iron wire knots to make the steel balls coaxial and fixed. Then, by starting the motor to rotate the threaded screw, the pressure is applied from the pressure shovel of the screw to the variable circumference iron ring, then transmitted to the steel balls, then to the iron sheet, and finally to the sealing rubber ring, and the force is evenly distributed, which improves the probability of explosion-proof chamber at the bottom of the irregular inclined column. Moreover, the size of the steel balls can be changed to fit the iron sheet well. The placement of steel balls according to the shape of the irregular inclined column makes the device reusable, overcoming the defects of construction technology. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] This embodiment provides a bottom grouting explosion-proof chamber device adapted to different large irregular inclined columns. It includes a preferred embodiment of the device, which is adaptable to different large irregular inclined columns 500. The device includes a motor drive assembly 4, which has an outer casing 402 and a pressurizing assembly 1 below it. The motor drive assembly 4 drives the threaded screw 104 of the pressurizing assembly 1 via a motor 401, transmitting pressure to a force-bearing assembly 2. The force-bearing assembly 2 then transmits pressure to a sheet metal 301 in a sealing assembly 3 via an internal steel ball 202. Due to the rigidity of the sheet metal 301, the pressure is evenly transmitted to a sealing rubber ring 302 in the sealing assembly 3. The sealing rubber ring 302, due to its fit against the bottom of the irregular inclined column 500 and its own elasticity, achieves a good seal between the bottom of the irregular inclined column 500 and the ground under the pressure of the sheet metal 301, thus achieving a sealing effect.

[0032] Furthermore, the motor drive assembly 4 includes a motor 401, a housing 402, and a connecting bolt 403. The motor 401 is connected to the threaded screw 104, and the housing 402 covers the inner iron ring 203 from the iron ring 101 with the threaded hole 105.

[0033] Furthermore, the coupling 103 of the pressurizing assembly 1 connects the threaded screw 104 to the motor 401. After the motor 401 starts rotating, the threaded screw 104 is driven to rotate through the coupling 103.

[0034] Furthermore, the force-bearing component 2 includes a wire knot 201, which fixes multiple steel balls 202, and several wire knots 201 are fixed on the outer wall of a perforated variable circumference iron ring.

[0035] Furthermore, the outermost steel ball 202 of the plurality of steel balls 202 is attached to the inner wall of the inner iron ring 203, the innermost steel ball 202 is attached to the outer wall of the iron sheet 301, and a row of steel balls 202 is arranged coaxially and fastened by iron wire knot 201.

[0036] Furthermore, the sealing component 3 includes a sheet metal 301, which is made according to the circumference and shape of the irregular inclined column 500, so that the pressure is evenly transmitted to the sealing rubber ring 302, and the inner side of the sheet metal 301 is tightly attached to the sealing rubber ring 302.

[0037] Furthermore, the sealing component 3 includes a sealing rubber ring 302, the inner side of which is in close contact with the bottom of the irregular inclined column 500 to seal the mortar and prevent leakage of mortar from the irregular inclined column 500.

[0038] In use, the two parts of the explosion-proof chamber device must first be moved to both sides of the large irregular inclined column 500. Then, adjust the angle so that the connecting bolts 403 of the two parts are aligned. Adjust the distance to make the connecting bolts 403 fit together and tighten the connecting bolts 403 of the two parts to complete the fixation of the device. After that, calculate the perimeter of the irregular inclined column 500 according to the construction drawings. Use a sealing rubber ring 302 of the same perimeter to wrap around the bottom outside of the irregular inclined column 500, and then place a sheet metal 301 that fits the shape of the irregular inclined column 500. Then, according to the shape of the irregular inclined column 500, place steel balls 202 of different diameters to fill the sheet metal 301 and the variable perimeter internal steel balls. The space between the rings is used to fix the steel ball 202 with iron wire, and then the motor 401 is driven. The motor 401 rotates the threaded screw 104, which causes the force-bearing shovel at the bottom of the threaded screw 104 to provide pressure to squeeze the variable circumference iron ring, i.e., the inner iron ring 203. The inner iron ring 203 tightens and squeezes the steel ball 202. The steel ball 202 transmits the force to the iron sheet 301. Due to its rigidity, the iron sheet 301 transmits the force evenly to the rubber ring, thereby achieving the function of sealing the bottom of the irregularly shaped inclined column 500. Moreover, the sealing rubber ring 302 and the iron sheet 301 can be recycled, which improves the assembly and construction efficiency and quality of the large irregularly shaped inclined column 500.
