Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a concrete pouring device. Background Art

[0002] In my country's construction industry, concrete rectangular columns are widely used and play a vital role in various building structures. However, during the construction of concrete square columns, some problems are often encountered, such as root rot after a period of time after pouring. This is mainly due to improper material ratio, inappropriate material selection, and poor environment of the bottom column. In order to solve this problem, it is necessary to repair and strengthen the concrete square column to ensure its quality and service life.

[0003] As attached Figure 1 As shown, for the reinforcement of a rectangular column with a large missing area, a deep depth and a depression at one corner, the prior art generally supports the formwork around the square column and leaves a filling port on the formwork. Concrete with a higher concrete grade than the original concrete grade is pumped into the depressed position through the filling port at high pressure by a concrete grouting pump. After a period of time, the formwork is removed and related maintenance is carried out.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The invention is used for repairing and reinforcing the depressions at the corners of a rectangular parallelepiped concrete column with rotten roots.

[0025] like Figure 2-Figure 10 As shown, the present invention provides a technical solution: a concrete pouring device, including a support plate 1, a support plate 2, a grouting machine and a vibrating rod 7. The grouting machine is composed of a pump body, a stirring device, a conveying pipeline and a control system. The concrete grouting is extracted from the stirring device through the pump body, and then conveyed to the position that needs to be repaired or reinforced through the conveying pipeline. The vibrating rod 7 is connected to the motor through a hose body, and the motor provides power for the vibration of the vibrating rod 7. The grouting machine and the vibrating rod 7 are both existing technologies and will not be repeated in this solution.

[0026] Bottom plate 101 and bottom plate 201 are respectively arranged on the outside of support plate 1 1 and support plate 2 2, and bottom plate 101 and bottom plate 2 201 are fixed to the ground by anchor bolts or other connection methods. In this solution, support plate 1 1 and bottom plate 101 and support plate 2 2 and bottom plate 2 201 are movably connected by plug-in parts; like Figure 3 and Figure 5 As shown, the plug-in portion includes a dovetail groove 102 opened at the bottom of the bottom plate 101 and the bottom plate 201, and dovetail blocks are fixed at the bottom of the support plate 1 and the support plate 2. The dovetail block on one side is adapted to the dovetail groove 102. It can be understood that the dovetail block and the dovetail groove 102 can also be replaced by other adaption structures that can enable the support plate 1 to move horizontally on the side of the bottom plate 101 and the support plate 2 to move horizontally on the side of the bottom plate 201. There can be multiple dovetail grooves 102 and dovetail blocks on one side. In this solution, in order to ensure the connection stability of the support plate 1 and the support plate 2, the number of dovetail grooves 102 on one side is set to two, and they are symmetrically arranged on both sides of the bottom plate 101 and the bottom plate 2, respectively.

[0027] The support plate 1 and the support plate 2 are connected by a connecting portion. In order to seal the depressions at the corners of the rectangular column (hereinafter referred to as the square column), it can be understood that the end face of the support plate 1 fits the side face of the support plate 2, and the support plate 1 and the support plate 2 are perpendicular to each other. like Figure 3 and Figure 6 As shown, the connection portion includes a plurality of (in this embodiment, two) convex grooves 301 opened on the side of the support plate 2, an extension plate 302 is fixed to the end surface of the support plate 1, and a Z-shape is formed between the extension plate 302 and the support plate 1, and a convex block 303 is provided on the side of the extension plate 302, and the convex block 303 and the convex groove 301 are adapted. It can be understood that the convex block 303 and the convex groove 301 can also be replaced by other adapting structures that can realize the horizontal movement of the support plate 1 on the side of the support plate 2; What you need to know is that Figure 6 As shown, a lap joint surface 304 is formed between the support plate 1 and the support plate 2, and the lap joint surface 304 is located outside the convex groove 301; pass Figure 6 To explain, specifically, when support plate 22 abuts against the side of the square column, support plate 1 is pushed, and support plate 1 is limited by the dovetail block at the bottom and the convex block 303 on the side, so that support plate 1 can move horizontally against the surface of support plate 2. When support plate 22 abuts against the other side of the square column, the right side plate of support plate 1 is located on the right side of the convex groove 301. At this time, a lap joint 304 is formed between support plate 1 and support plate 2, and the lap joint 304 is located on the outside of the convex groove 301. The lap joint 304 can block the concrete injected into the depression of the square column to prevent the concrete from overflowing through the convex groove 301 due to the concrete entering the convex groove 301, which is convenient for the later demoulding of support plate 1 and support plate 2 and reduces the difficulty of cleaning support plate 2 and convex groove 301 in the later stage.

[0028] The plate body of the supporting plate 2 is fixedly connected with a feed pipe and a discharge pipe from bottom to top in sequence. The feed pipe is connected to the pipe of the grouting machine. The pipe bodies of the feed pipe and the discharge pipe are plugged with plugging heads. Before pouring concrete, the plugging heads are used to block the feed pipe and the discharge pipe to prevent impurities such as cement blocks from entering the pipe body of the feed pipe, thereby reducing the quality impact of impurities on the injected concrete. The discharge pipe is used to discharge the air in the depression of the square column when pouring concrete; like Figure 2 As shown, in another specific embodiment of the present scheme, an overflow groove 202 is opened on the inner side of the support plate 2, the recessed part of the square column corner is located in the overflow groove 202, the feed pipe and the discharge pipe are respectively arranged at the bottom and the top of the overflow groove 202, and the inner end faces of the feed pipe and the discharge pipe are located in the overflow groove 202.

[0029] In the prior art, it is necessary to open multiple discharge pipes on the support plate 2 to adapt to the square column depressions of different heights. Before construction, the height of the depression needs to be measured to determine which discharge pipe to open. In this solution, an overflow groove 202 is provided. This setting is to be able to discharge the air in the square column depressions of different heights, thereby effectively improving the formwork efficiency.

[0030] like Figure 2 As shown, the vibrating rod 7 is retractably arranged on the plate body of the supporting plate 2, and the vibrating rod 7 vibrates the filled concrete to increase the compactness of the filled concrete; Specifically, Figure 2 , Fig. 9 and Fig.10 As shown, a circular through hole is opened on the plate body of the support plate 2, and a support rod 801 is movably arranged in the circular through hole. The support rod 801 is fixed to the hose 701, and a cavity 802 is opened on the right side of the support rod 801, and the right side of the hose 701 is located in the cavity 802, and a rubber airbag 803 is fixed to the inner wall of the right cavity 802, and the vibration rod 7 is fixed to the inner wall of the rubber airbag 803, so that when the vibration rod 7 vibrates, the rubber airbag 803 produces elastic deformation under the vibration force of the vibration rod 7, so that it will not interfere with the vibration of the vibration rod 7, thereby realizing the vibration of the concrete. In addition, since the right side of the hose 701 can swing a certain amount in the cavity 802, it will also not interfere with the vibration of the vibration rod 7. Through the mutual cooperation of the above components, the vibration effect of the concrete is improved.

[0031] In order to remove the vibrating rod 7 from the concrete after the vibrating is completed, to prevent the vibrating rod 7 from being easily separated from the concrete after the concrete is solidified, and to improve the overall integrity of the solidified concrete, as shown in FIG. Fig. 9As shown, a telescopic assembly 9 is provided on the top of the support rod 801, wherein the telescopic assembly 9 includes an L-shaped plate 901 fixed on the support plate 2, a screw rod 902, a guide rod 903 and a motor 904, and the motor 904 is electrically connected to the controller, and the controller can be in the form of a remote control, a handheld controller or a control panel installed on the casting device; A thread block is fixed on the top of the support rod 801 , the thread block is movably screwed to the second threaded rod 902 and movably plugged to the guide rod 903 , and the output end of the motor 904 is fixed to the end of the second threaded rod 902 .

[0032] In this solution, in order to achieve precise control of the position of the support rod 801, the motor 904 is preferably a servo motor with controllable speed and high position accuracy.

[0033] Specifically, refer to Fig. 9 When the vibration is completed, the controller controls the motor 904 to start. When the motor 904 rotates, it drives the wire block and the support rod 801 to move outward, thereby driving the vibration rod 7 to move to the left, and then moving the vibration rod 7 out of the concrete. Similarly, through the control of the controller on the motor 904, the vibration rod 7 is moved deep into the appropriate position of the depression.

[0034] Since the concrete is still in a flowing state after the vibration is completed, in order to seal the circular through hole and prevent the concrete from flowing out through the circular through hole, Figure 4 and Fig. 9 As shown, a baffle 6 made of rubber material is provided at the end of the vibration rod 7. Fig. 9 As shown, a truncated cone block 601 is integrally formed on the left side of the baffle 6, and the outer diameter of the bottom of the truncated cone block 601 is not less than the inner diameter of the circular through hole; Reference Fig.10 To illustrate, when the support rod 801 moves to the leftmost position, the left side of the baffle plate 6 contacts the bottom wall of the groove 203, and the baffle plate 6 is located in the groove 203. At this time, the right edge of the truncated cone block 601 contacts the edge of the circular through hole, thereby achieving the blocking of the circular through hole. In addition, it can be known that since the baffle plate 6 and the truncated cone block 601 are made of rubber material, they have a certain elasticity. When the bottom of the truncated cone block 601 shrinks into the circular through hole, the bottom of the truncated cone block 601 can form a seal for the circular through hole, thereby preventing concrete from overflowing through the circular through hole. Therefore, in this solution, the outer diameter of the bottom of the truncated cone block 601 is not less than the inner diameter of the circular through hole. It can be understood that the shape of the truncated cone block 601 is not limited to a truncated cone shape. However, it should be made clear that the left diameter of all truncated cone blocks 601 is smaller than the rightmost diameter (the bottom of the truncated cone block 601). Taking the truncated cone block 601 as a column as an example, if the truncated cone block 601 is a column, in order to achieve the above-mentioned sealing effect, the side wall of the truncated cone block 601 is in contact with the side wall of the circular through hole. Since the truncated cone block 601 is in contact with the concrete during vibration, its outer surface is adhered to the concrete. When the concrete solidifies, the truncated cone block 601 is bonded to the inside of the circular through hole, making it difficult to disassemble, replace and reuse the baffle 6. In this solution, the truncated cone block 601 is set to a truncated cone shape. When the bottom of the truncated cone block 601 shrinks into the circular through hole, the contact area between the right edge of the truncated cone block 601 and the edge of the circular through hole is small, and the bonding force between the truncated cone block 601 and the circular through hole is small, which facilitates the later disassembly and assembly of the baffle 6 and its reuse.

[0035] In order to prevent the baffle plate 6 from separating from the vibration rod 7 when sealing the circular through hole, a plurality of annular grooves are opened on the right side of the vibration rod 7, and a plurality of anti-slip rings 602 are integrally formed on the inner side of the baffle plate 6, and the anti-slip rings 602 are adapted to the annular grooves.

[0036] In addition, when the vibrating rod 7 is moved out of the concrete until the baffle 6 blocks the circular through hole, part of the concrete paddle will flow out through the circular through hole. At this time, workers are required to clean this small part of the concrete to prevent the solidified concrete from adhering to the outer wall of the circular through hole, thereby reducing the difficulty of later cleaning.

[0037] In addition, in the present solution, the baffle 6 is located in the groove 203 and the inner end faces of the above-mentioned feed pipe and discharge pipe are located in the overflow groove 202. The purpose of this setting is to achieve that after the concrete in the depression is poured and solidified, only bulges will be present on the surface of the solidified concrete without forming a concave surface. It can be known that repairing the concave surface again will affect the overall strength of the concrete. In this way, when the construction is completed, only the bulge needs to be cut and polished, which will not affect the overall strength of the concrete.

[0038] like Figure 3 and Figure 7 As shown, a pressing assembly 4 is provided on the outer side of the support plate 1 and the support plate 2, wherein the pressing assembly 4 includes a connecting plate 401, two inclined plates 402 are fixed on both sides of the connecting plate 401, and a movable roller 403 is movably connected between the inclined plates 402 on one side through a connecting shaft; A movable seat 1 404 and a movable seat 2 511 are respectively arranged at the bottom of the connecting plate 401 outside the supporting plate 1 1 and the supporting plate 2 2. The movable seat 1 404 and the movable seat 2 511 are respectively movably arranged in the rectangular groove 1 and the rectangular groove 2. In this scheme, side blocks are formed at the bottom of the movable seat 1 404 and the movable seat 2 511, and side grooves matching the side blocks are opened on the sides of the rectangular groove 1 and the rectangular groove 2. In this way, the movable seat 1 404 and the movable seat 2 511 can only move horizontally in the rectangular groove 1 and the rectangular groove 2, and a spring 2 509 is fixed between one side wall of the rectangular groove and the movable seat 1 404; like Figure 4 , Figure 7 , Figure 8 As shown, a power assembly 5 is provided at the top of the bottom plate 201, wherein Figure 7 As shown, the power assembly 5 includes a double-headed hydraulic cylinder 501 fixed on the top of the second bottom plate 201, and the ends of the two telescopic rods of the double-headed hydraulic cylinder 501 are respectively provided with a push part 1 and a push part 2; It should be understood that the pushing part 2 and the pushing part 1 push the movable rollers 403 on both sides in turn, and the movable rollers 403 on both sides push the support plate 2 2 and the support plate 1 1 in turn, so that the support plate 2 2 and the support plate 1 1 are respectively squeezed against the two side surfaces of the rectangular concrete column, that is, in this scheme, the support plate 2 2 is first pushed by the pushing part 2, so that the support plate 2 2 squeezes the side surface of the square column, and then the support plate 1 1 is pushed by the pushing part 1, so that the support plate 1 squeezes the other side of the depression, so that the depression of the square column to be repaired is surrounded between the support plate 2 2 and the support plate 1 1.

[0039] In order to realize the automatic control of the movement of the support plate 2 and the support plate 1, and improve the automation degree of the concrete pouring device, as Figure 7 As shown, in another specific embodiment of the present scheme, a side plate is provided on the side of the connecting plate 401, and four plug shafts 111 movably connected to the connecting plate 401 are fixed on the inner side of the side plate, and four springs 112 are fixed between the side plate and the connecting plate 401, and the plug shaft 111 is located in the spiral circle of the spring 112. A pressure sensor 10 is also fixed on the inner side of the side plate. In this embodiment, the movable seat 1 404 and the movable seat 2 511 are respectively fixed to the two side plates, and the pressure sensor 10 transmits the squeezing force of the pressure sensor 10 on the connecting plate 401 to the controller in real time.

[0040] like Figure 7 As shown, the pusher part 1 includes a first tooth plate 502, a rotating shaft 1 503 and a rotating shaft 2 504, a first gear 510 is fixed on the left shaft of the rotating shaft 1 503, and the first gear 510 is meshed with the first tooth plate 502; In order to realize that the support plate 2 can move on the side of the support plate 1 without affecting the power transmission of the rotating shaft 1 503 in the later stage, a circular groove is opened on the right side of the rotating shaft 1 503, and a plurality of guide grooves 506 are opened on the outer side of the circular groove, and a plurality of guide blocks 505 are fixed on the left shaft body of the rotating shaft 2 504, and the guide blocks 505 are adapted to the guide grooves 506. In this way, when the support plate 2 is fixed, the support plate 1 is pushed, and the rotating shaft 2 504 moves horizontally in the circular groove on the right side of the rotating shaft 1 503. Since the guide grooves 506 limit the guide blocks 505, when the rotating shaft 2 504 rotates, it can drive the rotating shaft 1 503 to rotate synchronously; In order to push the connecting plate 401 , a cam 507 is fixed on the shaft of the second rotating shaft 504 , and the cam 507 is in contact with the end surface of the second movable seat 511 .

[0041] Since the contact area between the cam 507 and the end face of the movable seat 2 511 is large, the power consumption is increased. In a preferred scheme of this embodiment, a plurality of semi-circular balls 508 are fixed on the end face of the movable seat 1 404. At this time, the cam 507 is in contact with the side of the semi-circular ball 508, and the total contact area is small, thereby reducing the power consumption of the system.

[0042] like Figure 8 As shown, the pushing part 2 includes a second tooth plate, a push rod 512 and a rotating shaft 3 513. A second gear is fixed on the rod body of the rotating shaft 3 513, and the second gear is meshed with the second tooth plate. A screw rod 1 514 is fixed on the side of the push rod 512. The screw rod 1 514 is movably screwed to the right side shaft body of the rotating shaft 3 513. In this way, when the second tooth plate drives the second gear to rotate, the second gear drives the rotating shaft 3 513 to rotate, thereby realizing the horizontal movement of the screw rod 1 514 in the rotating shaft 3 513, thereby realizing the pushing of the side plate on the side of the support plate 2 2.

[0043] The present invention also proposes a method for repairing concrete corner defects of a square column: Step 1: First, remove the loose concrete at the repaired part; Step 2: Clean the chiseled area with a brush and rinse it with water. Keep it fully moist for more than 24 hours. Before pouring concrete, there should be no visible water on the surface of the chiseled area. Step 3: pouring concrete into the part to be repaired by using a concrete pouring device; Step 4: When the strength of the poured concrete reaches the set requirements, the concrete pouring device is removed; Step 5: Sprinkle water on the final setting concrete 4-6 times a day for 10-14 days; Step 6: Cut the protrusions formed on the concrete surface after curing and polish the concrete surface.

[0044] To supplement step 3, Figure 3 , Figure 6-Figure 8 As shown, the support plate 1 and the support plate 2 are moved to the outside of the defective part of the square column, the bottom plate 201 is pushed until the support plate 201 contacts the side of the square column, and the bottom plate 201 is fixed to the ground. When the support plate 1 is pushed, the support plate 1 drives the support plate 1 and the bottom plate 101 to move to the right, and the bottom plate 101 is pushed until the support plate 1 contacts the other side of the square column, and then the bottom plate 101 is fixed to the ground; The left rod of the double-headed hydraulic cylinder 501 is extended by the controller, and the second gear plate drives the second gear to rotate when it moves. Since the rotating shaft 3 513 is movably screwed with the screw rod 1 514 and the side plate is movably arranged on the top of the bottom plate 201 through the movable seat 2 511, the screw rod 1 514 moves to the right, and the push rod 512 pushes the side plate and the movable seat 2 511 to move to the right. At this time, the side plate and the connecting plate 401 are close to each other, the spring 112 contracts, and the movable roller 403 generates an extrusion force on the support plate 2 2, so that the support plate 2 2 is pressed against the side of the square column to fix the support plate 2 2. At this time, extrusion is generated between the pressure sensor 10 and the connecting plate 401, and the pressure value of the pressure sensor 10 is transmitted to the controller in real time. When the pressure value reaches the set value, the controller controls the left rod of the double-headed hydraulic cylinder 501 to stop extending. The controller controls the right rod of the double-head hydraulic cylinder 501 to extend. Figure 7 As shown, the first toothed plate 502 drives the first gear 510 to rotate, and when the first gear 510 rotates, it drives the rotating shaft 1 503 and the rotating shaft 2 504 to rotate synchronously, and when the cam 507 rotates, it pushes the semicircular ball 508, so that the movable seat 1 404 and the side plate move to the right side, as described above, the movable roller 403 squeezes the support plate 1 1, and similarly, when the pressure value of the pressure sensor 10 on this side reaches the set value, the controller controls the right rod body of the double-headed hydraulic cylinder 501 to stop extending, and finally the support plate 1 1 and the support plate 2 2 squeeze the two sides of the column; The working principles of the remaining components have been explained above and will not be repeated here; It should be noted that the pressure threshold of the pressure sensor 10 can be determined through a limited number of tests, and the determination principle is that the vibration force generated by the vibration rod 7 during vibration will not affect the support of the support plate 1 and the support plate 2 2 to the side of the column.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
