Description

Technical Field

[0001] The invention belongs to the field of civil engineering construction, in particular to a supporting structure for reinforced concrete beam and column casting construction and a construction method thereof. Background Art

[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, it 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 during the initial setting stage.

[0003] In the existing technology, wooden boards are generally used for fencing. However, the wooden boards fit tightly to the outer walls of reinforced concrete beams and columns, making it difficult for water to come into contact with the reinforced concrete beams and columns after watering, thereby inhibiting the concrete hydration reaction and affecting the concrete strength. In addition, during the hydration process of the concrete, its slurry components will come into 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

[0005] In order to make up for the shortcomings of the existing technology and solve the problem that wooden boards are generally used for fencing in the existing technology, however, the wooden boards are closely attached to the outer walls of the reinforced concrete beams and columns, which makes it difficult for water to contact the reinforced concrete beams and columns after watering, so that the concrete hydration reaction is inhibited, affecting the concrete strength. 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 is likely to bond with the formwork. When the wooden boards are dismantled, part of the concrete will be taken away, resulting in partial loss of the reinforced concrete beams and columns.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0039] like Figures 1 to 11As shown, the present invention provides a technical solution, a support structure for reinforced concrete beam and column casting construction, including a base 1, the inner wall of the base 1 is equidistantly slidably connected to four groups of limit shafts 2, one end of the four groups of limit shafts 2 is fixedly connected to a support seat 3, the tops of the four support seats 3 are fixedly connected to a side plate 6, the outer walls of the four support seats 3 are fixedly connected to a fixing frame 19, the inner walls of the four fixing frames 19 are fixedly connected to a sliding shaft 20, the outer walls of the four sliding shafts 20 are slidably connected to a slider 21, and the outer walls of the four sliding shafts 20 are fixedly connected to the slider 21. 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 is rotatably connected to the four sliders 21 respectively, 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 the bracket 23, the top of the bracket 23 is fixedly connected to the water baffle 24, and the top of the water baffle 24 is fixedly connected to the hanging ring 43.

[0040] After the concrete is completely dry and solid, the four first knobs 5 are rotated in the opposite direction to make the four side plates 6 move away from each other. When the four side plates 6 are separated from the reinforced concrete beam and column, the base 1 is conveniently removed by hooking the lifting ring 43 on the outside of the four side plates 6.

[0041] 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, and 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.

[0042] 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 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, further prevent rainwater from entering, and can keep the concrete moist, avoiding a large amount of water volatilization 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.

[0043] Specifically, the inner wall of the cover 28 is equidistantly and slidingly connected with four blocks 32, one end of each of the four blocks 32 is fixedly connected to a second spring 33, one end of each of the four second springs 33 is fixedly connected to the cover 28, and the other ends of the four blocks 32 extend to the inside of the four slots 31 respectively. The bottoms of the four blocks 32 are all set to be inclined surfaces, and the outer wall of the insert block 29 is provided with a card slot 30 for cooperating with the block 32, and an unlocking unit is provided at the bottom of the water baffle 24.

[0044] With the above technical solution, when the four inserting blocks 29 are respectively inserted into the four slots 31, the top of the inserting block 29 presses against the inclined surface of the bottom of the card block 32. As the cover plate 28 moves downward, the inserting block 29 pushes the card block 32 to move to one side, pressing the second spring 33. When the inserting block 29 is completely inserted into the slot 31, the card block 32 is pushed back to its original position under the action of the second spring 33, so that the card block 32 is inserted into the card groove 30 on the outer wall of the inserting block 29. The inserting block 29 is limited by the card block 32, so that the inserting 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 inserting 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 dry reinforced concrete beams and columns. Because the four side panels 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 panels 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, pressing the four first springs 22. When the cover plate 28 moves upward a part, the unlocking unit is provided to separate the card block 32 from the insert block 29. Under the action of the four side panels 6's own gravity and the elastic force of the four first springs 22, the support seat 3 and the side panels 6 move downward and reset. At this time, it is convenient to move the four side panels 6 horizontally to open the four side panels 6.

[0045] Specifically, the unlocking unit includes four top plates 36, which are fixedly connected to the bottom of the water baffle 24 at equal distances. The four top plates 36 are all 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.

[0046] With the above technical solution, the top plate 36 is set to press against the inner wall of the through groove 35, so that the card block 32 presses the second spring 33. When the cover plate 28 moves downward, the top plate 36 is pulled out from the through groove 35. After losing the squeezing of the top plate 36, the card block 32 moves and resets under the action of the second spring 33. After the card block 32 resets, one end of the card block 32 enters the slot 31. When the cover plate 28 moves upward, it drives the card block 32 and the insert block 29 to move upward at the same time. When the card 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 card block 32. Under the squeezing of the top plate 36, the card block 32 moves to one side and presses the second spring 33. After the card block 32 moves, it separates from the insert block 29.

[0047] 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. Four water outlet grooves 26 are fixedly connected to the bottom of the water baffle 24 at equal intervals. The four water outlet grooves 26 are all connected to the guide groove 25. The outer walls of the four side panels 6 are fixedly connected with funnels 12. The four water outlet grooves 26 are respectively located directly above the four funnels 12.

[0048] 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 outlet grooves 26, and falls into the four funnels 12 for storage.

[0049] Specifically, a slot 7 is provided on the inner wall of the side panel 6, and a baffle 9 is slidably connected to the inner wall of the side panel 6. One side of the baffle 9 extends to the interior of the slot 7, and the other side of the baffle 9 is fixedly connected to a fixed plate 8. The fixed plate 8 is slidably connected to the side panel 6. A second threaded rod 10 is threadedly connected to the inner wall of the side panel 6, and one end of the second threaded rod 10 is rotatably connected to the fixed plate 8. The other end of the second threaded rod 10 is fixedly connected to a second knob 11. A water inlet 13 is provided on the outer wall of the side panel 6, and one end of the water inlet 13 extends to the interior of the funnel 12. The other end of the water inlet 13 is communicated with the top of the slot 7. 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 slot 7.

[0050] Through the above technical solution, the baffle 9 is set to block the water inlet 13 to prevent the rainwater in the funnel 12 from being transported downward, avoiding 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, 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, which is convenient for 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.

[0051] 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.

[0052] Through the above technical solution, the contact area between concrete and water is expanded by providing a plurality of strip grooves, making it easier for concrete to absorb water.

[0053] Specifically, a water accumulation chamber 16 is provided inside the four support seats 3, a water inlet groove 15 is provided on the top of the four support seats 3, the water inlet groove 15 is communicated with the water outlet 14, and the top of the four support seats 3 is fixedly connected to a first hydraulic cylinder 17, and the output end of the first hydraulic cylinder 17 is fixedly connected to the inside of the water accumulation chamber 16 and a piston plate 18, which fits the inner wall of the water accumulation chamber 16.

[0054] Through the above technical solution, the water not absorbed by the concrete is easily discharged through the provided water inlet trough 15. At this time, the concrete is in a saturated state. Continuous immersion in water will cause the concrete surface to become loose. The water not absorbed by the concrete flows along the water inlet trough 15 into the water accumulation chamber 16, thereby collecting excess water and preventing the excess water from corroding the roots of reinforced concrete beams and columns. When the concrete needs to be hydrated again, the first hydraulic cylinder 17 controls the piston plate 18 to move upward. 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 the concrete again, thereby maximizing the utilization rate of water and avoiding the waste of water resources.

[0055] Specifically, the inner wall of the base 1 is equidistantly and slidingly connected to four first rods 37, the inner walls of the four first rods 37 are rotatably connected to the third threaded rod 38, the outer wall of the third threaded rod 38 is threadedly connected to the sleeve 40, the inner wall of the first rod 37 is equidistantly and slidingly connected to four groups of second rods 42, the top of the second rod 42 is rotatably connected to the 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 to the third knob 39.

[0056] Through the above technical solution, when the base 1 is sleeved on the outside of the steel beam column, the four first rods 37 are hammered downward to insert the four first rods 37 into the foundation, thereby making the position of the base 1 firm and preventing deviation when pouring concrete. After the four first rods 37 are inserted into the foundation, the four third knobs 39 are turned to move the four sleeves 40 downward. When the sleeves 40 move downward, the four groups of second rods 42 are pushed to slide outward through the connecting shaft 41, so that the four groups of second rods 42 are also inserted into the foundation. The position of the base 1 is fixed by further limiting the four groups of second rods 42.

[0057] A construction method for a support structure for reinforced concrete beam and column casting construction, which is applicable to the above-mentioned support structure for reinforced concrete beam and column casting construction, and the steps of the construction method are as follows:

[0058] 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;

[0059] S2: Turn the four first knobs 5 to move the four side panels 6 closer to each other and dock them to form a mold. Pour concrete between the four side panels 6. After the concrete dries and solidifies, a reinforced concrete beam column is formed. Activate the second hydraulic cylinder 27 to push the cover plate 28 downward so that the cover plate 28 docks with the four side panels 6.

[0060] S3: During the initial setting stage of the concrete, the second knob 11 is turned to move the baffle 9 out of the empty slot 7. The water in the funnel 12 enters the empty slot 7 through the water inlet 13 and flows downward along the empty slot 7 to contact the concrete, causing the concrete to absorb the water and undergo a hydration reaction.

[0061] S4: After the concrete is dry and solidified, the second hydraulic cylinder 27 is activated 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.

[0062] When in use, the base 1 is lifted by hooking the lifting ring 43 with a crane and sleeved on the steel beam column, and the lifting ring 43 is loosened so that the base 1 supports the steel beam column. When the base 1 is sleeved on the outside of the steel beam column, the four first plug rods 37 are hammered downward so that the four first plug rods 37 are inserted into the foundation, thereby firmly positioning the base 1 to prevent deviation during concrete pouring. After the four first plug rods 37 are inserted into the foundation, the four third knobs 39 are turned to move the four sleeves 40 downward. When the sleeves 40 move downward, the four groups of second plug rods 42 are pushed outward by the connecting shaft 41, so that the four groups of second plug rods 42 are also inserted into the foundation. The position of the base 1 is firmly fixed by further limiting the four groups of second plug rods 42. 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 approach each other, so that the four side panels 6 are close to each other and docked to form a mold, and concrete is poured between the four side panels 6. After the concrete is dried, a reinforced concrete beam column is formed. The water retaining plate 24 is provided to block rainwater during rain, to prevent rainwater from mixing with concrete and affecting the drying of the concrete. 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 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, 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 docked with the four side panels 6, the four plug blocks 29 are respectively inserted into the four slots 31, and the tops of the four side panels 6 are limited by the cooperation of the four plug blocks 29 and the four slots 31 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, and 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, avoiding soaking of rainwater when the concrete is not solidified. Watering is required for hydration reaction in the initial setting stage of the concrete. Turning the second knob 11 drives the second threaded rod 10 to move, so that the fixed plate 8 moves, and drives the baffle 9 to move, so that the baffle 9 moves out of the empty slot 7, and the baffle 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 and undergo hydration reaction. The contact area between the concrete and the water is expanded by the provision of 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 not absorbed by the concrete can be easily discharged through the provision of the water inlet groove 15. At this time, the concrete is in a saturated state. Continuous immersion in water will cause the concrete surface to become loose. The water not absorbed by the concrete flows along the water inlet groove 15 into the water accumulation chamber 16, thereby collecting excess rainwater and preventing excess water from eroding the roots of reinforced concrete beams and columns.When the concrete needs to be hydrated again, the first hydraulic cylinder 17 controls the piston plate 18 to move upward. The water in the water accumulation chamber 16 is squeezed into the empty groove 7 by the squeezing 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 pressed against the inner wall of the through groove 35 by the provided top plate 36, so that the clamping 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 squeezing of the top plate 36 is lost, the clamping 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, pressing the second spring 33. When the block 29 is completely inserted into 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 press the block 32 to move to the side. The second hydraulic cylinder 27 controls the cover plate 28 to move upward, so that the four inserts 29 move upward, drive the four side panels 6 to move upward, and move the four support seats 3 upward. When the four side panels 6 move upward, they can be separated from the dry reinforced concrete beams and columns. Because the four side panels 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 panels 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 certain distance, the top plate 36 presses against the inclined slot 34 at the top of the block 32. Under the pressure of the top plate 36, the block 32 moves to the side and compresses the second spring 33. After the block 32 moves, it separates from the insert 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 rotate the four first knobs 5 in the opposite direction to move the four side plates 6 away from each other. When the four side plates 6 are separated from the reinforced concrete beam column, the base 1 can be easily removed by hooking the lifting ring 43 with a crane.
