Description

Technical Field

[0001] The invention relates to the technical field of construction equipment, and in particular to a supporting device for super-thick raft slabs with multiple layers of steel bars. Background Art

[0002] In recent years, with the emergence of super-high-rise buildings, the thickness of raft foundations has continued to increase. Traditional raft foundation reinforcement is a double-layer, bidirectional, large-diameter steel mesh. However, ultra-thick raft foundations require an additional steel mesh in the middle, and then the upper, middle, and lower layers of steel mesh are reinforced by corresponding steel mesh support mechanisms.

[0003] In the process of implementing this application, it was found that the technology has the following problems: the existing support devices for multi-layer steel bars of ultra-thick raft slabs mostly use central columns for support, but most hollow columns need to be poured with concrete inside for waterproofing after the raft slab is built, which increases the subsequent construction costs and thus reduces the practicality of the equipment.

[0004] Therefore, a supporting device for multi-layer steel bars of an ultra-thick raft is proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that the existing support devices for multi-layer steel bars of ultra-thick raft slabs mostly use central columns for support, but most hollow columns need to be poured with concrete for waterproofing after the raft slab is built, which increases the subsequent construction cost. The present invention provides a support device for multi-layer steel bars of ultra-thick raft slabs.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] A support device for multi-layer steel bars of an ultra-thick raft slab comprises a cement base and fixed columns, wherein the fixed columns are placed on the upper surface of the cement base, a positioning mechanism for limiting the position of the fixed columns at the upper end of the cement base is provided inside the cement base, and a waterproof mechanism for preventing water from flowing back along the fixed columns is provided inside the fixed columns.

[0008] Furthermore, the waterproof mechanism includes a rubber plug, which is clamped inside the fixed column, and a groove is provided on the upper surface of the rubber plug. An air pipe is inserted into the groove of the rubber plug, and an annular air bag is sleeved on the outer surface of the air pipe. An air nozzle is provided on the upper surface of the air pipe, and a groove is provided on the outer surface of the air pipe. A connecting pipe is provided on the inner wall of the annular air bag, and the connecting pipe is installed inside the groove of the air pipe.

[0009] Furthermore, a protective cover is clamped inside the fixed column, and the lower surface of the protective cover abuts against the upper surface of the annular airbag.

[0010] Furthermore, the positioning mechanism includes four groups of limiting steel bars and a U-shaped steel cage. The four groups of limiting steel bars and the U-shaped steel cage are all installed inside the cement base. The U-shaped steel cage is sleeved on the outer ends of the four groups of limiting steel bars, and the adjacent sides of the four groups of limiting steel bars are all abutted against the outer surface of the fixed column.

[0011] Furthermore, protective cover plates are installed on the upper surfaces of the four groups of limiting steel bars.

[0012] Furthermore, the inner contour of the protective cover plate is adapted to the outer contour of the fixed column.

[0013] Furthermore, the four corners of the protective cover are all configured as arc-shaped rounded corners.

[0014] Furthermore, the protective cover is made of rubber.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention pushes the gas transmission mechanism to connect the exhaust end of the gas transmission device to the inside of the gas nozzle, so that the gas subsequently entering the gas transmission pipe is input into the inside of the annular airbag along the connecting pipe, thereby causing the subsequent annular airbag to expand. After the annular airbag expands, the outer surface of the annular airbag abuts against the inside of the fixed column, allowing the subsequent waterproof mechanism to fill and seal the inside of the fixed column, thereby allowing the subsequent waterproof mechanism to replace concrete to fill the inside of the fixed column, thereby reducing the use cost of the subsequent fixed column, thereby improving the practicality of the device.

[0017] 2. The present invention increases the contact surface between the subsequent four groups of limiting steel bars and the inside of the cement base through the U-shaped steel cage, so that the subsequent U-shaped steel cage increases the stability of the four groups of limiting steel bars during use, thereby minimizing the bending of the four groups of limiting steel bars when the subsequent fixed columns are hit, which causes the contact surface between the subsequent cement base and the four groups of limiting steel bars to crack, thereby improving the stability of the subsequent positioning mechanism during use.

Therefore, they cannot be understood as limitations on the present invention.

[0028] like Figures 1 to 5The support device of multi-layer steel bars of ultra-thick raft slab is shown, comprising a cement base 1 and a fixed column 3, the fixed column 3 is placed on the upper surface of the cement base 1, and a positioning mechanism 2 is provided inside the cement base 1 to limit the fixed column 3 to the upper end position of the cement base 1, and a waterproof mechanism 6 is provided inside the fixed column 3 to prevent water from flowing back along the fixed column 3; specifically, by opening the waterproof mechanism 6 and making the outer surface of the waterproof mechanism 6 abut against the inner wall of the fixed column 3, the subsequent waterproof mechanism 6 fills and seals the interior of the fixed column 3, so that the subsequent waterproof mechanism 6 replaces concrete to fill the interior of the fixed column 3, thereby reducing the use cost of the subsequent fixed column 3, thereby improving the practicality of the device; by increasing the contact surface between the positioning mechanism 2 and the cement base 1, the subsequent fixed column 3 is prevented from shaking when it is hit, thereby avoiding the contact surface between the subsequent cement base 1 and the positioning mechanism 2 from cracking, thereby improving the stability of the subsequent positioning mechanism 2 during use.

[0029] like Figures 3 to 5 As shown, the waterproof mechanism 6 includes a rubber plug 601, which is clamped in the interior of the fixed column 3. A groove is provided on the upper surface of the rubber plug 601. An air pipe 603 is inserted into the groove of the rubber plug 601. An annular air bag 602 is sleeved on the outer surface of the air pipe 603. An air nozzle 604 is provided on the upper surface of the air pipe 603. A groove is provided on the outer surface of the air pipe 603. A connecting pipe 605 is provided on the inner wall of the annular air bag 602. The connecting pipe 605 is installed in the groove of the air pipe 603. Specifically, when the subsequent fixed column 3 is retained in the raft, the air pipe 603 is pushed into the raft. The dynamic gas transmission mechanism connects the exhaust end of the gas transmission equipment to the inside of the gas nozzle 604, so that the gas subsequently entering the inside of the gas transmission pipe 603 is input into the inside of the annular airbag 602 along the connecting pipe 605, thereby causing the subsequent annular airbag 602 to expand. After the annular airbag 602 expands, the outer surface of the annular airbag 602 abuts against the inside of the fixed column 3, so that the subsequent waterproof mechanism 6 fills and seals the inside of the fixed column 3, so that the subsequent waterproof mechanism 6 replaces concrete to fill the inside of the fixed column 3, thereby reducing the use cost of the subsequent fixed column 3, thereby improving the practicality of the device.

[0030] like Figure 1 and Figure 2 As shown, a protective cover 5 is clamped inside the fixed column 3, and the lower surface of the protective cover 5 abuts against the upper surface of the annular airbag 602; specifically, the protective cover 5 is clamped to the inside of the fixed column 3 by pushing the protective cover 5, so that the subsequent protective cover 5 seals and blocks the opening at the top of the fixed column 3, thereby minimizing the possibility that the subsequent air nozzle 604 is blocked by debris during daily use, and preventing subsequent debris from entering the interior of the fixed column 3 and causing the subsequent annular airbag 602 to be scratched, thereby improving the service life of the subsequent waterproof mechanism 6.

[0031] like Figure 1 and Figure 2 As shown, the positioning mechanism 2 includes four groups of limiting steel bars 201 and a U-shaped steel cage 202. The four groups of limiting steel bars 201 and the U-shaped steel cage 202 are all installed inside the cement base 1. The U-shaped steel cage 202 is sleeved on the outer ends of the four groups of limiting steel bars 201, and the adjacent sides of the four groups of limiting steel bars 201 are all in contact with the outer surface of the fixed column 3; specifically, the U-shaped steel cage 202 increases the contact surface between the subsequent four groups of limiting steel bars 201 and the inside of the cement base 1, so that the subsequent U-shaped steel cage 202 increases the stability of the four groups of limiting steel bars 201 during use, thereby avoiding as much as possible that the four groups of limiting steel bars 201 are bent when the subsequent fixed column 3 is hit, causing the contact surface between the subsequent cement base 1 and the four groups of limiting steel bars 201 to crack, thereby improving the stability of the subsequent positioning mechanism 2 during use.

[0032] like Figure 1 and Figure 2 As shown, a protective cover plate 4 is installed on the upper surface of the four groups of limiting steel bars 201; specifically, the protective cover plate 4 is positioned at the upper end of the four groups of limiting steel bars 201, so that the subsequent protective cover plate 4 blocks the top of the four groups of limiting steel bars 201, thereby minimizing the risk of subsequent workers stepping on the four groups of limiting steel bars 201 during the process of laying the raft slab and causing injuries to the subsequent workers, thereby improving the safety of the subsequent device during use.

[0033] like Figure 1 and Figure 2 As shown, the inner contour of the protective cover plate 4 is adapted to the outer contour of the fixed column 3; specifically, by adapting the inner contour of the protective cover plate 4 to the outer contour of the fixed column 3, the subsequent protective cover plate 4 performs secondary positioning on the position of the fixed column 3 at the upper end of the cement base 1, thereby minimizing the bending of the subsequent four sets of limiting steel bars 201 during use, which may cause the subsequent fixed column 3 to move.

[0034] like Figure 1 and Figure 2 As shown, the four corners of the protective cover plate 4 are all set to arc-shaped rounded corners; specifically, by setting the four corners of the protective cover plate 4 to arc-shaped rounded corners, subsequent staff are not easily injured when colliding with the four corners of the protective cover plate 4, thereby improving the safety of the subsequent protective cover plate 4 during use.

[0035] like Figure 1 and Figure 2As shown, the material of the protective cover 5 is rubber; specifically, because the rubber has good corrosion resistance, the subsequent protective cover 5 is not easily corroded when in contact with cement for a long time, thereby minimizing damage to the subsequent protective cover 5 after long-term contact with cement, thereby improving the service life of the subsequent protective cover 5.

[0036] In summary: by pushing the gas transmission mechanism to connect the exhaust end of the gas transmission equipment to the inside of the gas nozzle 604, the gas subsequently entering the inside of the gas transmission pipe 603 is input into the inside of the annular airbag 602 along the connecting pipe 605, thereby causing the subsequent annular airbag 602 to expand, and then the outer surface of the annular airbag 602 after expansion abuts against the inside of the fixed column 3, so that the subsequent waterproof mechanism 6 fills and seals the inside of the fixed column 3, so that the subsequent waterproof mechanism 6 replaces concrete to fill the inside of the fixed column 3, thereby reducing the subsequent use cost of the fixed column 3; by pushing the protective cover 5 to clamp the protective cover 5 to the inside of the fixed column 3, the subsequent protective cover 5 seals and blocks the opening at the top of the fixed column 3, thereby minimizing the subsequent gas nozzle 604 from being blocked by debris during daily use, and preventing subsequent debris from entering the inside of the fixed column 3 and causing the subsequent annular airbag 602 to be scratched.
