Description

Technical Field

[0001] The invention relates to the technical field of construction, in particular to a prefabricated concrete frame construction structure. Background Art

[0002] At present, the construction of concrete frame structures mainly relies on the construction of traditional structures, such as transfer stations, concrete frame structure factories, etc. The concrete frame structure is mainly composed of columns and beams, which are connected by rigid or hinged joints to form a load-bearing system structure, that is, the frame composed of beams and columns jointly resists the horizontal and vertical loads that occur during use.

[0003] After searching, the Chinese patent number CN107419802A discloses a precast concrete frame structure and construction method. The frame structure includes a precast frame column structure and a connecting beam. The precast frame column structure includes a precast concrete column and a precast concrete beam. The precast concrete beam and the precast concrete column are vertically connected to each other and cast as one piece. The precast frame column structures are connected in the horizontal direction by connecting beams. The ends of the precast concrete columns are pre-embedded with connectors. The precast frame column structures are connected in the vertical direction by connectors, and concrete is poured on the outside of the connectors. The construction method includes: constructing a cap; supporting formwork, tying steel bars, burying connectors, and pouring concrete to obtain a precast concrete frame column structure, cutting steel plates, assembling and welding to obtain an H-shaped steel beam; hoisting one side and the other side of the precast frame column structure onto the cap respectively; installing the H-shaped steel beam; fixing the connectors, and pouring concrete. The structure and construction method can save formwork and building materials, improve construction efficiency, and purify the construction environment.

[0004] After searching, the Chinese patent number CN116810981A discloses a precast concrete frame construction structure, which relates to the field of precast concrete frame technology and solves the problem that the precast concrete frame construction structure is connected and assembled by traditional bolts, nuts and other connectors, and this connection method is very slow in installation and disassembly. A precast concrete frame construction structure includes a first connection frame, a second connection frame is provided at the rear end of the first connection frame, and main end plates are inserted on the front and rear sides of the first connection frame and the second connection frame, and side end plates are inserted on both sides between the first connection frame and the second connection frame. In the present invention, the user only needs to press the pressing column downward to realize the disassembly of the first connection frame and the second connection frame, and pull the pull plate on the outside of the outer cylindrical tube to realize the matching connection of the integral pressing column and the connecting long plate, so that the operation of assembling the overall precast frame structure is simple and convenient without bolts, nuts and other connectors.

[0005] After the assembly and assembling of the frame is completed, a pouring device is generally required to complete the pouring work. However, the bottom of the existing pouring device generally needs to be provided with a supporting structure corresponding to the frame height to facilitate the completion of the pouring work, that is, the height of the pouring structure needs to be adjusted according to the height of the frame, which not only requires additional supporting support structures, but also takes a certain amount of time when using the supporting structures. Summary of the invention

[0006] The purpose of the present invention is to provide a prefabricated concrete frame construction structure, which solves the problem that the height cannot be adjusted in the background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: A precast concrete frame construction structure comprises a fixed frame, one side of the fixed frame is provided with a lifting mechanism for pouring fixed frames of different heights, and the top of the lifting mechanism is provided with a moving mechanism for adjusting the pouring head forward and backward; The lifting mechanism is arranged on both sides of the fixed frame, and the lifting mechanism can be raised and lowered to adjust the height of the moving mechanism relative to the pouring head, so as to match the height of different fixed frames; The moving mechanism comprises a pouring device, and the pouring device can move in the front-rear direction to facilitate pouring at different positions.

[0008] It can be known from the above technical scheme that the double-axis motor is started through the cooperation between the double-axis motor and the bidirectional screw rod. Since the double-axis motor and the bidirectional screw rod are rotationally connected through the coupling, the bidirectional screw rod will rotate with the starting of the double-axis motor, and drive the two connecting blocks to move closer or farther away from each other, and at the same time drive the rotating plates to rotate, so as to adjust the height of the supporting frame. Since the casting device is arranged on the top of the supporting frame, starting the double-axis motor can adjust the height of the casting device, and can adapt to fixed frames of different heights for casting.

[0009] Preferably, the lifting mechanism includes a base plate, a mounting seat is fixedly connected to the top of the base plate, a dual-axis motor is fixedly connected in the inner cavity of the mounting seat located on the left side, a support plate is fixedly connected to the top of the base plate, a bidirectional screw is rotatably connected between the mounting seat and the support plate, the output shaft of the dual-axis motor and the bidirectional screw are fixedly connected via a coupling, the outer ring of the bidirectional screw is threadedly connected to a connecting block, and the connecting block moves with the rotation of the bidirectional screw.

[0010] Preferably, a rotating plate is hinged on the top of the connecting block, a connecting plate is hinged on the top of the rotating plate, a rotating rod is fixedly connected to the front of the output shaft of the dual-axis motor, a connecting rod is fixedly connected to the front of the bidirectional screw rod on the right side, the rotating rod and the connecting rod are connected by a belt, and the rotation angle and direction of the dual-axis motor can be manually controlled.

[0011] It can be known from the above technical scheme that a belt connection is provided between the rotating rod and the connecting rod through the cooperation between the rotating rod and the connecting rod. Therefore, when the rotating rod rotates, it can drive the connecting rod to rotate, and at the same time drive the bidirectional screw rod on the right side to rotate, thereby achieving the effect of simultaneous rotation of the bidirectional screw rods on the left and right sides, and then achieving the effect of simultaneous lifting and lowering of the support frames on the left and right sides, thereby improving the lifting stability.

[0012] Preferably, a limiting rod is fixedly connected between the mounting seat and the support plate, and the limiting rods are provided in multiple groups and are symmetrically distributed. The limiting rods are inserted into the inner cavity of the connecting block, and the limiting rods can make the movement of the connecting block more stable.

[0013] Preferably, a support frame is provided on the top of the connecting plate, a sliding block is fixedly connected to the top of the connecting plate, a sliding groove is provided on the bottom of the supporting frame, and the sliding block slides in the inner cavity of the sliding groove.

[0015] Through the above technical scheme, it can be known that by cooperating with the servo motor and the one-way screw, the servo motor is started, and the start of the servo motor can drive the one-way screw to rotate. Since the outer ring of the one-way screw is threadedly connected with a first moving block, the first moving block will move with the rotation of the one-way screw, and the first moving block is fixed to the fixed rod, and the fixed rod is fixed to the casting device. Therefore, starting the servo motor can drive the casting device to move forward and backward, which is convenient for the staff to adjust the front and rear position of the casting device.

[0016] Preferably, a fixing block is fixedly connected to the top of the support frame on the right side, a moving rod is fixedly connected between the fixing blocks, and a second moving block is sleeved on the outer ring of the moving rod.

[0017] Preferably, the top of the fixed frame is fixedly connected to a connecting frame, the top of the connecting frame is fixedly connected to an electric push rod, a baffle is slidably connected in the inner cavity of the fixed frame, and the baffle is fixedly connected to the electric push rod.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. In the present invention, the double-axis motor is started through the cooperation of the double-axis motor and the double-axis screw rod. Since the double-axis motor and the double-axis screw rod are rotationally connected through a coupling, the double-axis screw rod will rotate as the double-axis motor is started, and drive the two connecting blocks to move closer to or away from each other, and at the same time drive the rotating plates to rotate, so that the height of the supporting frame can be adjusted. Since the casting device is arranged on the top of the supporting frame, starting the double-axis motor can adjust the height of the casting device, and can adapt to fixed frames of different heights for casting.

[0021] 2. In the present invention, a belt connection is provided between the rotating rod and the connecting rod through the cooperation between the rotating rod and the connecting rod. Therefore, when the rotating rod rotates, it can drive the connecting rod to rotate, and at the same time drive the bidirectional screw rod on the right side to rotate, thereby achieving the effect of simultaneous rotation of the bidirectional screw rods on the left and right sides, and then achieving the effect of simultaneous lifting and lowering of the support frames on the left and right sides, thereby improving the lifting stability.

[0022] 3. In the present invention, the servo motor is started through the cooperation of the servo motor and the one-way screw. The start of the servo motor can drive the one-way screw to rotate. Since the outer ring of the one-way screw is threadedly connected with the first moving block, the first moving block will move with the rotation of the one-way screw. The first moving block is fixed to the fixed rod, and the fixed rod is fixed to the casting device. Therefore, starting the servo motor can drive the casting device to move forward and backward, which is convenient for the staff to adjust the front and rear position of the casting device.

[0029] like Figure 7 and Figure 8 As shown, a limiting rod 12 is fixedly connected between the mounting seat 3 and the supporting plate 5 . The limiting rods 12 are provided in multiple groups and are symmetrically distributed. The limiting rods 12 are inserted into the inner cavity of the connecting block 7 .

[0030] like Figure 3 As shown, a support frame 13 is provided on the top of the connecting plate 9, a slider 14 is fixedly connected to the top of the connecting plate 9, a slide groove 15 is provided at the bottom of the support frame 13, and the slider 14 slides in the inner cavity of the slide groove 15.

[0031] The working principle of the embodiment of the present invention is: during the rotation of the dual-axis motor 4, it can drive the rotating rod 10 to rotate. Since a belt connection is provided between the rotating rod 10 and the connecting rod 11, when the rotating rod 10 rotates, it can drive the connecting rod 11 to rotate, and at the same time drive the bidirectional screw rod 6 on the right to rotate.

[0032] Embodiment 2; See also Figure 1-Figure 8 In the embodiment of the present invention, a fixed block 21 is fixedly connected to the top of the support frame 13 on the right side, a moving rod 22 is fixedly connected between the fixed blocks 21, and a second moving block 23 is sleeved on the outer ring of the moving rod 22. A connecting frame 24 is fixedly connected to the top of the fixed frame 1, an electric push rod 25 is fixedly connected to the top of the connecting frame 24, a baffle 26 is slidably connected in the inner cavity of the fixed frame 1, and the baffle 26 is fixedly connected to the electric push rod 25.

[0033] The working principle of the embodiment of the present invention is: since the pouring device 20 is arranged on the top of the supporting frame 13, starting the dual-axis motor 4 can adjust the height of the pouring device 20, and can adapt to the fixed frames 1 of different heights for pouring.

[0034] Embodiment 3; See also Figure 1-Figure 8 In the embodiment of the present invention, a telescopic rod 27 is fixedly connected between the connecting frame 24 and the baffle 26. Two groups of telescopic rods 27 are provided and are symmetrically distributed with the connecting frame 24. A cover plate 28 is hinged on the back of the fixed frame 1. Two groups of mounting seats 3 are provided and are symmetrically distributed with the fixed frame 1. Two groups of support plates 5 are provided and are symmetrically distributed with the fixed frame 1. Two groups of support frames 13 are provided and are symmetrically distributed with the fixed frame 1.

[0035] The working principle of the embodiment of the present invention is: start the electric push rod 25, the electric push rod 25 contracts and drives the baffle 26 to move upward. Since the baffle 26 is slidably connected in the fixed inner cavity, when the baffle 26 rises, the front of the fixed frame 1 can be opened.

[0036] Working principle: The pouring device 20 is connected to the concrete hose, which pumps out concrete. As the pouring device 20 sprays out concrete, it enters the interior of the fixed frame 1. Since the fixed frame 1 is in a sealed state during use, the cover plate 28 is in a closed state, and the baffle 26 drops to the bottom of the inner cavity of the fixed frame 1, it can prevent the concrete from flowing out.

[0037] When it is necessary to adjust the front and rear position of the pouring device 20, start the servo motor 16. The start of the servo motor 16 can drive the one-way screw 17 to rotate. Since the outer ring of the one-way screw 17 is threadedly connected to the first moving block 18, the first moving block 18 will move with the rotation of the one-way screw 17. The first moving block 18 is fixed to the fixed rod 19, and the fixed rod 19 is fixed to the pouring device 20. Therefore, starting the servo motor 16 can drive the pouring device 20 to move forward and backward, which is convenient for the staff to adjust the front and rear position of the pouring device 20.

[0038] Since different fixed frames 1 have different heights, in order to be able to cast fixed frames 1 of different heights, the dual-axis motor 4 is started at this time. Since the dual-axis motor 4 and the bidirectional screw 6 are rotatably connected through a coupling, the bidirectional screw 6 will rotate with the start of the dual-axis motor 4, and drive the two connecting blocks 7 to move closer to or away from each other, and at the same time drive the rotating plates 8 to rotate, so that the height of the supporting frame 13 can be adjusted. Since the casting device 20 is arranged on the top of the supporting frame 13, starting the dual-axis motor 4 can adjust the height of the casting device 20, and can adapt to fixed frames 1 of different heights for casting.

[0039] During the rotation of the dual-axis motor 4, the rotating rod 10 can be driven to rotate. Since a belt connection is provided between the rotating rod 10 and the connecting rod 11, the rotating rod 10 can drive the connecting rod 11 to rotate when it rotates, and at the same time drive the bidirectional screw rod 6 on the right to rotate, thereby achieving the effect of simultaneous rotation of the bidirectional screw rods 6 on the left and right sides, and then achieving the effect of simultaneous lifting of the support frames 13 on the left and right sides, thereby improving the lifting stability.

[0040] When the solidified concrete needs to be demoulded, the electric push rod 25 is started, the electric push rod 25 contracts and drives the baffle 26 to move upward. Since the baffle 26 is slidably connected in the fixed inner cavity, when the baffle 26 rises, the front of the fixed frame 1 can be opened. At this time, the solidified concrete wall inside the fixed frame 1 is pushed, and the concrete wall can be pushed out from the back of the fixed frame 1, thereby improving the convenience of removal.

[0041] Although the 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 alterations may be made to the embodiments without departing from the principles and spirit thereof, and the scope of the present invention is defined by the appended claims and their equivalents.
