Description

Technical Field

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. In civil engineering and municipal engineering, concrete and other materials are put into a mold to form a predetermined shape. When pouring concrete, the free height of the concrete should not exceed 2m. When it exceeds 3m, corresponding measures should be taken. During the pouring process, the pouring needs to be completed in one go, and the duration of vibration should be enough to produce floating slurry on the surface of the concrete, without bubbles and without sinking. When pouring reinforced concrete beams and columns, guard plates are needed to support the reinforced concrete beams and columns, and the poured concrete needs to be watered for hydration reaction in the initial setting stage.

[0003] In the existing technology, wooden boards are generally used for fencing. However, the wooden boards are closely attached to the outer walls of reinforced concrete beams and columns, which makes it difficult for water to contact the reinforced concrete beams and columns after watering, so that the hydration reaction of the concrete is inhibited, affecting the strength of the concrete. In the hydration process of the concrete, its slurry components will be in close contact with the surface of the wooden boards. When the concrete gradually hardens, the cement slurry and the formwork are prone to bonding. When the wooden boards are removed, part of the concrete will be taken away, resulting in partial loss of the reinforced concrete beams and columns.

[0004] To this end, the present invention provides a support structure for reinforced concrete beam and column casting construction and a construction method thereof. Summary of the invention

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 11As shown, the present invention provides a technical solution, a support structure for reinforced concrete beam-column casting construction, comprising a base 1, the inner wall of the base 1 is equidistantly slidably connected with four groups of limit shafts 2, one end of the four groups of limit shafts 2 is fixedly connected with a support seat 3, the tops of the four support seats 3 are fixedly connected with side plates 6, the outer walls of the four support seats 3 are fixedly connected with fixed frames 19, the inner walls of the four fixed frames 19 are fixedly connected with sliding shafts 20, the outer walls of the four sliding shafts 20 are slidably connected with sliders 21, and the outer walls of the four sliding shafts 20 are A first spring 22 is sleeved, the top of the first spring 22 is fixedly connected to the slider 21, the bottom of the first spring 22 is fixedly connected to the fixing frame 19, the inner wall of the base 1 is equidistantly threaded with four first threaded rods 4, one end of the four first threaded rods 4 are respectively rotatably connected to the four sliders 21, and the other ends of the four first threaded rods 4 are fixedly connected to the first knob 5, the top of the base 1 is fixedly connected to a bracket 23, the top of the bracket 23 is fixedly connected to a water baffle 24, and the top of the water baffle 24 is fixedly connected to a hanging ring 43.

[0024] Through the above technical scheme, the base 1 is lifted by hooking the lifting ring 43 with a crane, and is put on the reinforced beam column, the lifting ring 43 is loosened, so that the base 1 supports the reinforced beam column, the four first knobs 5 are turned to drive the four first threaded rods 4 to approach each other, and the four first threaded rods 4 push the four support seats 3 to approach each other, so that the four side panels 6 are approached to each other and connected to form a mold, concrete is poured between the four side panels 6, and before vibrating the concrete between the four side panels 6, steel wire ropes are wound around the outer sides of the four side panels 6 for tightening, and the wound steel wire ropes are untied after the concrete is initially set, and reinforced concrete beam columns are formed after the concrete is dried. The water retaining plate 24 is set to block rainwater during rain to prevent rainwater from mixing with concrete and affecting the drying of concrete. After the concrete is completely dried, the four first knobs 5 are rotated in the opposite direction to make the four side panels 6 move away from each other. When the four side panels 6 are separated from the reinforced concrete beam column, the base 1 is conveniently removed by hooking the lifting ring 43 with a crane.

[0025] Specifically, the bottom of the water baffle 24 is fixedly connected to the second hydraulic cylinder 27, the output end of the second hydraulic cylinder 27 is fixedly connected to the cover plate 28, the bottom of the cover plate 28 is equidistantly provided with four slots 31, the tops of the four side panels 6 are fixedly connected to the plug blocks 29, and the four plug blocks 29 are respectively attached to the inner walls of the four slots 31.

[0026] Through the above technical solution, after the four side panels 6 are docked and concrete is poured, the second hydraulic cylinder 27 is started to push the cover plate 28 to move downward so that the cover plate 28 is docked with the four side panels 6. The cover plate 28 can protect the top of the concrete to further prevent rainwater from entering, and can keep the concrete moist to avoid a large amount of water evaporation when the concrete is not solidified. After the cover plate 28 is docked with the four side panels 6, the four plug blocks 29 are respectively inserted into the four slots 31. Through the cooperation of the four plug blocks 29 and the four slots 31, the tops of the four side panels 6 are limited to prevent the tops of the four side panels 6 from bulging outward due to excessive concrete pressure.

[0027] Specifically, the inner wall of the cover plate 28 is equidistantly and slidably connected with four blocks 32, one end of each of the four blocks 32 is fixedly connected with a second spring 33, one end of each of the four second springs 33 is fixedly connected to the cover plate 28, the other ends of the four blocks 32 extend to the inside of four slots 31 respectively, the bottoms of the four blocks 32 are all set as inclined surfaces, the outer wall of the insert block 29 is provided with a slot 30 used to cooperate with the block 32, and an unlocking unit is provided at the bottom of the water baffle 24.

[0028] Through the above technical solution, when the four plug blocks 29 are respectively inserted into the four slots 31, the top of the plug block 29 presses against the inclined surface of the bottom of the block 32. As the cover plate 28 moves downward, the plug block 29 pushes the block 32 to move to one side and compresses the second spring 33. When the plug block 29 completely enters the slot 31, the second spring 33 pushes the block 32 to reset, so that the block 32 is inserted into the slot 30 on the outer wall of the plug block 29. The block 32 limits the plug block 29 so that the plug block 29 is fixed in the cover plate 28. After the concrete is dried, the cover plate 28 is controlled to move upward by the second hydraulic cylinder 27, so that the four plug blocks 29 move upward, driving the four side plates 6 to move upward, so that the four support seats 3 move upward. When the plate 6 moves upward, it can be separated from the solid reinforced concrete beams and columns. Because the four side plates 6 are always close to the surface of the reinforced concrete beams and columns when moving upward, the tearing force on the reinforced concrete beams and columns is small, which effectively prevents the side plates 6 from carrying part of the concrete when demoulding, resulting in partial loss of the reinforced concrete beams and columns. After the four support seats 3 move upward, they drive the four fixing frames 19 to move upward and press the four first springs 22. When the cover plate 28 moves upward for a while, the unlocking unit is set to separate the block 32 from the plug block 29. Under the action of the gravity of the four side plates 6 themselves and the elastic force of the four first springs 22, the support seat 3 and the side plates 6 move downward and reset. At this time, it is convenient to move the four side plates 6 horizontally to open the four side plates 6.

[0029] Specifically, the unlocking unit includes four top plates 36, which are fixedly connected to the bottom of the water retaining plate 24 at equal distances, and the four top plates 36 are slidably connected to the cover plate 28. The top of the block 32 is provided with an inclined groove 34 for cooperating with the top plate 36, and the bottom of the block 32 and one side close to the inclined groove 34 is provided with a through groove 35, and the top plate 36 fits the inner wall of the through groove 35.

[0030] Through the above technical solution, the top plate 36 is set to press against the inner wall of the through groove 35, so that the block 32 presses the second spring 33. When the cover plate 28 moves downward, the top plate 36 is pulled out of the through groove 35. After losing the pressure of the top plate 36, the block 32 moves and resets under the action of the second spring 33. After the block 32 is reset, one end of the block 32 enters the slot 31. When the cover plate 28 moves upward, the block 32 and the plug block 29 are driven to move upward at the same time. When the block 32 moves to the position of the top plate 36, the top plate 36 presses against the inclined groove 34 at the top of the block 32. Under the pressure of the top plate 36, the block 32 moves to one side and presses the second spring 33. After the block 32 moves, it is separated from the plug block 29.

[0031] Specifically, a guide groove 25 is provided on the top of the water baffle 24. The guide groove 25 is arranged in a ring shape and the inner wall is arranged in a ring shape. The bottom of the water baffle 24 is equidistantly and fixedly connected with four water outlet grooves 26. The four water outlet grooves 26 are all connected with the guide groove 25. The outer walls of the four side plates 6 are fixedly connected with funnels 12. The four water outlet grooves 26 are respectively located directly above the four funnels 12.

[0032] Through the above technical solution, the water baffle 24 can catch rainwater when it rains. The rainwater flows along the guide groove 25, falls from the four water outlet grooves 26, and falls into the four funnels 12 for storage.

[0033] Specifically, a hollow groove 7 is provided on the inner wall of the side panel 6, and a baffle plate 9 is slidably connected to the inner wall of the side panel 6, one side of the baffle plate 9 extends into the interior of the hollow groove 7, and a fixing plate 8 is fixedly connected to the other side of the baffle plate 9, and the fixing plate 8 is slidably connected to the side panel 6, and a second threaded rod 10 is threadedly connected to the inner wall of the side panel 6, one end of the second threaded rod 10 is rotatably connected to the fixing plate 8, and the other end of the second threaded rod 10 is fixedly connected to a second knob 11, and a water inlet 13 is provided on the outer wall of the side panel 6, one end of the water inlet 13 extends to the interior of the funnel 12, and the other end of the water inlet 13 is communicated with the top of the hollow groove 7, and a water outlet 14 is provided at the bottom of the side panel 6, and the water outlet 14 is communicated with the bottom of the hollow groove 7.

[0034] Through the above technical scheme, the water inlet 13 is blocked by the baffle 9 to prevent the rainwater in the funnel 12 from being transported downward, so as to avoid soaking in rainwater when the concrete is not solidified. Watering is required for hydration reaction in the initial setting stage of the concrete. The second knob 11 is turned to drive the second threaded rod 10 to move, so that the fixed plate 8 moves, and the baffle 9 is driven to move, so that the baffle 9 moves out of the empty groove 7. After the baffle 9 moves, the water inlet 13 is no longer blocked. The rainwater in the funnel 12 enters the empty groove 7 along the water inlet 13 and flows downward along the empty groove 7, so as to be in contact with the concrete, so that the concrete can absorb water for hydration reaction. When the stored rainwater is used up, water can be poured into the funnel 12 in the same way.

[0035] Specifically, the empty slot 7 is composed of a transverse slot and a plurality of strip slots, and the baffle 9 is composed of a transverse plate and a plurality of strip plates.

[0036] Through the above technical solution, the contact area between concrete and water is expanded by setting a plurality of strip grooves, making it easier for concrete to absorb water.

[0037] Specifically, a water accumulation chamber 16 is provided inside each of the four support seats 3, a water inlet groove 15 is provided on the top of each of the four support seats 3, the water inlet groove 15 is communicated with the water outlet 14, a first hydraulic cylinder 17 is fixedly connected to the top of each of the four support seats 3, and a piston plate 18 is fixedly connected to the inside of the water accumulation chamber 16 at the output end of the first hydraulic cylinder 17, and the piston plate 18 fits the inner wall of the water accumulation chamber 16.

[0038] Through the above technical solution, the water not absorbed by the concrete is easily discharged through the water inlet trough 15. At this time, the concrete is in a saturated state. Continuous immersion in water will cause the concrete surface to loosen. The water not absorbed by the concrete enters the water accumulation chamber 16 along the water inlet trough 15, thereby collecting excess water and avoiding the erosion of the roots of reinforced concrete beams and columns by excess water. When the concrete needs to be hydrated again, the piston plate 18 is controlled to move upward by the first hydraulic cylinder 17. Through the extrusion of the piston plate 18, the water in the water accumulation chamber 16 is squeezed into the empty groove 7 and contacts with the concrete again, thereby maximizing the utilization rate of water and avoiding the waste of water resources.

[0039] Specifically, the inner wall of the base 1 is equidistantly slidably connected with four first plug rods 37, the inner walls of the four first plug rods 37 are rotatably connected with a third threaded rod 38, the outer wall of the third threaded rod 38 is threadedly connected with a sleeve 40, the inner wall of the first plug rod 37 is equidistantly slidably connected with four groups of second plug rods 42, the top of the second plug rod 42 is rotatably connected with a connecting shaft 41, the connecting shaft 41 is rotatably connected to the sleeve 40, and the top of the third threaded rod 38 is fixedly connected with a third knob 39.

[0040] Through the above technical solution, when the base 1 is sleeved on the outside of the steel beam column, the four first plug rods 37 are hammered downward to make the four first plug rods 37 inserted into the foundation, thereby making the position of the base 1 firm and preventing deviation when pouring concrete. After the four first plug rods 37 are inserted into the foundation, the four third knobs 39 are turned to make the four sleeves 40 move downward. When the sleeves 40 move downward, the four groups of second plug rods 42 are pushed to slide outward through the connecting shafts 41, so that the four groups of second plug rods 42 are also inserted into the foundation. Through the further limitation of the four groups of second plug rods 42, the position of the base 1 is fixed.

[0041] A construction method of a support structure for reinforced concrete beam and column casting construction, the construction method is applicable to the above-mentioned support structure for reinforced concrete beam and column casting construction, the construction method steps are as follows: S1: Use a crane to hook the lifting ring 43 to lift the base 1, and put it on the steel beam column, loosen the lifting ring 43, so that the base 1 supports the steel beam column; S2: Turn the four first knobs 5 to make the four side panels 6 approach each other and butt together to form a mold, pour concrete between the four side panels 6, and after the concrete is dried and solidified, form a reinforced concrete beam column, start the second hydraulic cylinder 27, push the cover plate 28 downward, and make the cover plate 28 butt together with the four side panels 6; S3: In the initial setting stage of concrete, the second knob 11 is turned to move the baffle 9 out of the empty slot 7, and the water in the funnel 12 enters the empty slot 7 along the water inlet 13, and flows downward along the empty slot 7 to contact the concrete, so that the concrete absorbs water to perform a hydration reaction; S4: After the concrete is dried and solidified, the second hydraulic cylinder 27 is started to control the cover plate 28 to move upward, and the four side plates 6 are separated from the reinforced concrete beam column by pulling upward.

[0042] When in use, the base 1 is lifted by hooking the lifting ring 43 with a crane and sleeved on the steel beam column, the lifting ring 43 is loosened to make the base 1 support the steel beam column, and when the base 1 is sleeved on the outside of the steel beam column, the four first plug rods 37 are hammered downward to make the four first plug rods 37 inserted into the foundation, thereby making the position of the base 1 firm to prevent deviation when pouring concrete, after the four first plug rods 37 are inserted into the foundation, the four third knobs 39 are turned to make the four sleeves 40 move downward, and when the sleeves 40 move downward, the four groups of second plug rods 42 are pushed to slide outward through the connecting shaft 41, so that the four groups of second plug rods 42 are also inserted into the foundation, and the position of the base 1 is firm through the further limiting of the four groups of second plug rods 42, and the four first knobs 5 are turned to drive the four The first threaded rods 4 are close to each other, and the four first threaded rods 4 push the four support seats 3 to be close to each other, so that the four side panels 6 are close to each other and connected to form a mold, and concrete is poured between the four side panels 6. After the concrete is dried and solidified, a reinforced concrete beam column is formed. The water retaining plate 24 is provided to block rainwater during rain, so as to prevent rainwater from mixing with concrete and affecting the drying of concrete. After the four side panels 6 are connected and concrete is poured, the second hydraulic cylinder 27 is started to push the cover plate 28 to move downward so that the cover plate 28 is connected to the four side panels 6. The cover plate 28 can protect the top of the concrete, further prevent rainwater from entering, and can keep the concrete moist to avoid a large amount of water volatilization when the concrete is not solidified. After the cover plate 28 is connected to the four side panels 6, the four plug blocks The four side panels 6 are respectively inserted into the four slots 31. The four insert blocks 29 cooperate with the four slots 31 to limit the tops of the four side panels 6 to prevent the tops of the four side panels 6 from bulging outwards due to excessive concrete pressure. The water baffle 24 can catch rainwater when it rains. The rainwater flows along the guide groove 25, flows down from the four water outlet grooves 26, and falls into the four funnels 12 for storage. The water inlet 13 is blocked by the baffle 9 to prevent the rainwater in the funnel 12 from being transported downward, so as to avoid soaking in rainwater when the concrete is not solidified. Watering is required for hydration reaction in the initial setting stage of the concrete. The second knob 11 is turned to drive the second threaded rod 10 to move, so that the fixed plate 8 moves, and the baffle 9 moves, so that the baffle 9 moves out of the empty slot 7, and the baffle 9 is blocked. After the plate 9 moves, it no longer blocks the water inlet 13. The rainwater in the funnel 12 enters the empty groove 7 along the water inlet 13 and flows downward along the empty groove 7, making it easy to contact with the concrete, so that the concrete can absorb water for hydration reaction. The contact area between the concrete and the water is expanded by setting a plurality of strip grooves, making it easier for the concrete to absorb water. When the stored rainwater is used up, water can be poured into the funnel 12 in the same way. The water inlet groove 15 is set to facilitate the discharge of the water not absorbed by the concrete. At this time, the concrete is in a saturated state. Continuous immersion in water will cause the concrete surface to loosen. The water not absorbed by the concrete enters the water accumulation chamber 16 along the water inlet groove 15, thereby collecting excess rain and preventing the excess water from eroding the roots of reinforced concrete beams and columns.When the concrete needs to be hydrated again, the piston plate 18 is controlled to move upward by the first hydraulic cylinder 17. The water in the water accumulation chamber 16 is squeezed into the empty groove 7 by the extrusion of the piston plate 18 and contacts the concrete again, thereby maximizing the utilization rate of water and avoiding the waste of water resources. The top plate 36 is set to press against the inner wall of the through groove 35, so that the block 32 presses the second spring 33. When the cover plate 28 moves downward, the top plate 36 is pulled out of the through groove 35. After the extrusion of the top plate 36 is lost, the block 32 moves and resets under the action of the second spring 33. After the block 32 is reset, one end of the block 32 enters the slot 31. When the four insert blocks 29 are respectively inserted into the four slots 31, the top of the insert block 29 presses against the inclined surface of the bottom of the block 32. As the cover plate 28 moves downward, the insert block 29 pushes the block 32 to move to one side and compresses the second spring 33. When the insert block 29 completely enters the slot 31, the second spring 33 pushes the block 32 to reset, so that the block 32 is inserted into the slot 30 on the outer wall of the block 29. The block 32 limits the block 29 so that the block 29 is fixed in the cover plate 28. After the concrete is dried, the second spring 33 is used to push the block 32 to reset. The second hydraulic cylinder 27 controls the cover plate 28 to move upward, so that the four plug blocks 29 move upward, drive the four side plates 6 to move upward, and move the four support seats 3 upward. When the four side plates 6 move upward, they can be separated from the dry reinforced concrete beams and columns. Because the four side plates 6 are always close to the surface of the reinforced concrete beams and columns when they move upward, the tearing force on the reinforced concrete beams and columns is small, which effectively prevents the side plates 6 from carrying part of the concrete when demoulding, resulting in the loss of part of the reinforced concrete beams and columns. After the four support seats 3 move upward, they drive the four fixing frames 19 to move upward, pressing the four first elastic Spring 22, when the cover plate 28 moves upward a section, the top plate 36 presses against the inclined groove 34 on the top of the block 32, and under the pressure of the top plate 36, the block 32 moves to one side and presses the second spring 33. After the block 32 moves, it separates from the plug 29. Under the action of the gravity of the four side plates 6 and the elastic force of the four first springs 22, the support seat 3 and the side plates 6 move downward and reset. At this time, it is convenient to reversely rotate the four first knobs 5 to make the four side plates 6 move away from each other. When the four side plates 6 are separated from the reinforced concrete beams and columns, the base 1 is conveniently removed by hooking the lifting ring 43 with a crane.
