Description

Technical Field

[0001] This invention relates to the field of precast concrete technology, and more specifically, to a tooling and method for producing precast concrete (PC) components. Background Technology

[0002] Currently, in the production of precast concrete (PC) components, most components require exposed reinforcing bars, and the side with exposed reinforcing bars needs to be roughened to increase adhesion with the concrete in the subsequent pouring. Existing methods mainly rely on drilling holes in the side formwork to allow the reinforcing bars to protrude through these holes. A retarder is then applied to the side formwork. After demolding, the mortar on the side with the retarder is washed away, exposing the aggregate to achieve the roughened surface. This method involves complex production processes and is costly.

[0003] A search revealed an auxiliary fixing device and special tooling for PC component production, with announcement number CN112223221B. The auxiliary fixing device uses a fixed clamping plate, a movable clamping plate, and a clamping guide rod. By using a quick clamping device that pushes and connects to the clamping guide rod, the clamping guide rod is moved forward and the reinforcing bars are locked, thus fixing the entire row of reinforcing bars on the formwork-free module. This makes the formwork-free module with reinforcing bars and the device form a rigid integral component. The special tooling has a simple structure and is easy to use, improving the application efficiency of formwork-free construction in prefabricated building component production.

[0004] The aforementioned auxiliary fixing device and special tooling for PC component production involves first inserting the open end of the U-shaped steel bar through the formwork and binding it to the formwork with wire to form a steel bar formwork module. Then, the auxiliary fixing device is placed on the steel bar formwork module. However, by first inserting each group of U-shaped steel bars through the formwork and binding them with wire, the positioning of the binding position of each group of U-shaped steel bars is prone to errors, which reduces the quality of the steel bar formwork module and affects subsequent production. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a tooling and method for producing concrete PC components. By sequentially inserting each group of U-shaped reinforcing bars into the corresponding U-shaped seats, pushing the outermost sliding rod, the first and second sliding parts of each group move synchronously toward the support plate, so that each group of pressure rods synchronously presses the corresponding U-shaped reinforcing bars, thus completing the synchronous and stable clamping of each group of U-shaped reinforcing bars.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0031] Example 1, please refer to Figure 1-11 The present invention provides the following technical solutions: A tooling for producing concrete PC components specifically includes a support frame 1; the support frame 1 includes a support plate 2; a plurality of bearing parts 3 are slidably arranged on the side of the support plate 2; the bearing parts 3 include U-shaped seats 4; L-shaped plates 5 are symmetrically fixed on two opposite sides of the U-shaped seats 4; a first sliding part 6 and a second sliding part 7 are slidably arranged on the two L-shaped plates 5 respectively.

[0032] The first sliding part 6 and the second sliding part 7 respectively include a first sliding sleeve 8 and a second sliding sleeve 9; a first half-connecting column 10 and a sliding rod 11 are fixed on two opposite sides of the first sliding sleeve 8; a U-shaped platform 12 and a guide tube 13 are fixed on two opposite sides of the second sliding sleeve 9; a rotating shaft 14 is rotatably arranged through the inner wall of the U-shaped platform 12; a pressure rod 15 is fixed on the circumferential side of the rotating shaft 14 and is perpendicular to it; a second half-connecting column 16 adapted to the adjacent first half-connecting column 10 is fixed at the end of the pressure rod 15; the guide tube 13 slides in cooperation with its adjacent sliding rod 11.

[0033] The top of the second sliding sleeve 9 is fixed with an arc-shaped tube 17; the top of the rotating shaft 14 is fixed with an arc-shaped plate 18 that slides with the arc-shaped tube 17; an arc-shaped spring 19 is connected between the arc-shaped plate 18 and the arc-shaped tube 17; a gear 20 is fixed at the bottom of the rotating shaft 14; a horizontal plate 21 is fixed on the side of the U-shaped seat 4; a toothed plate 22 that matches the gear 20 is fixed on the side of the horizontal plate 21.

[0034] The bottom surface of the support plate 2 is symmetrically and slidably provided with two base plates 23; a non-removable formwork 24 is placed at an inclination between the two base plates 23; a diagonal bracing plate 25 adapted to the non-removable formwork 24 is fixed on the surface of the base plate 23; a U-shaped groove 26 is opened in the inner wall of the U-shaped seat 4; a U-shaped steel bar 27 adapted to it is inserted into the U-shaped groove 26.

[0035] Working principle of this embodiment: Each group of U-shaped steel bars 27 is inserted into the corresponding U-shaped seat 4 in sequence. The outermost sliding rod 11 is pushed, which drives the first sliding part 6 and the second sliding part 7 of each group to move synchronously toward the support plate 2. This allows the pressure rods 15 of each group to press the corresponding U-shaped steel bars 27 synchronously, thus completing the synchronous and stable clamping of each group of U-shaped steel bars 27 and improving work efficiency. The support plate 2, which clamps and fixes the U-shaped steel bars 27, is controlled to slide toward the non-removable mold 24 until each group of U-shaped steel bars 27 is synchronously inserted into the non-removable mold 24. Then, each group of U-shaped steel bars 27 is fixed to the non-removable mold 24 by steel wire, completing the assembly of the non-removable mold module with steel bars. This ensures that the binding position of each group of U-shaped steel bars 27 is the same, improving the quality of the non-removable mold module with steel bars.

[0036] Example 2, please refer to Figure 1-11 This second embodiment is an improvement on the first embodiment as follows: Specifically, a T-shaped slide rail is fixed on the bottom surface of the support plate 2; a T-shaped groove is opened on the bottom surface of the base plate 23 to slide with the slide rail; a fixed seat 28 is fixed on the surface of the base plate 23; a first screw 29 is rotatably provided through the side of one fixed seat 28 to rotate with the threaded rotation of the support plate 2; a guide rod 30 is fixed on the side of another fixed seat 28 to slide through the support plate 2; and several connecting springs 31 are fixed between the ends of the first sliding sleeve 8 and the second sliding sleeve 9 and the corresponding L-shaped plate 5, respectively.

[0037] A limiting plate 32 is fixed to the side of the support plate 2; a limiting rail 33 is symmetrically fixed to the two opposite sides of the limiting plate 32; a limiting groove 34 is provided on the side of the U-shaped seat 4 to slide with the limiting plate 32; guide grooves 35 are symmetrically provided on both sides of the inner wall of the limiting groove 34 to slide with the limiting rail 33; a square column 36 is fixed to the side of the limiting plate 32; a guide sleeve 37 is slidably provided on the square column 36; a connecting rod 38 that slides with the adjacent guide tube 13 is fixed to one side of the guide sleeve 37.

[0038] The support plate 2 has lifting grooves 39 at both ends; an adjustment part 40 is slidably arranged between the two lifting grooves 39; the adjustment part 40 includes a cover plate 41; vertical plates 42 are fixed at both ends of the cover plate 41; lifting rails 43 that slide with the lifting grooves 39 are fixed on the side of the vertical plates 42; a first ear plate 44 is fixed on the side of the cover plate 41; a second ear plate 45 is fixed on the top of the support plate 2; a screw hole 46 is opened on the surface of the second ear plate 45; a second screw 47 that is screwed into the screw hole 46 is slidably arranged through the surface of the first ear plate 44.

[0039] An extension rod 48 is fixed to the side of the U-shaped seat 4; a guide ball 49 is fixed to the end of the extension rod 48; several guide parts 50 are evenly fixed to the bottom surface of the cover plate 41; the guide parts 50 are composed of guide rods whose outer diameter decreases sequentially from top to bottom; the connection between adjacent guide rods is chamfered; a return spring 51 is fixedly connected between the connecting rod 38 and the adjacent conduit 13 and between the slide rod 11 and the adjacent conduit 13.

[0040] The U-shaped base 4 has an insertion hole 52 on its side; the support plate 2 has an installation groove 53 on its side; a positioning part 54 is slidably arranged inside the installation groove 53; the positioning part 54 includes a sliding plate 55 that slides with the installation groove 53; a number of insertion parts 56 are evenly fixed on the side of the sliding plate 55; the insertion part 56 is composed of a number of insertion rods; the insertion hole 52 is inserted into the corresponding insertion rod.

[0041] The top of the slide plate 55 is fixed with an ear seat 57; the side of the ear seat 57 is provided with a sliding hole 58; the surface of the second ear plate 45 is provided with a sliding groove that slides with the ear seat 57; a fixing rod 59 that slides with the sliding hole 58 is fixed between the inner walls of the sliding groove; a compression spring 60 sleeved on the fixing rod 59 is fixedly connected between the ear seat 57 and the sliding groove.

[0042] A first threaded tube 61 is fixed through the other opposite side of the guide sleeve 37; a third screw 62 is screwed into the first threaded tube 61; a through hole 65 is opened on the side of the square column 36 to engage with the third screw 62; a baffle 63 is fixed on the side of the limiting plate 32; a second threaded tube 64 is rotatably provided on the side of the baffle 63 to engage with the adjacent slide rod 11.

[0043] Working principle of this embodiment two: In the initial state, under the elastic force of each set of reset springs 51, the guide balls 49 on each set of U-shaped seats 4 are pressed against the peripheral side of the guide rod at the bottom of the corresponding guide part 50, and the ear seat 57 is pulled outward along the sliding groove. The corresponding compression spring 60 is compressed, so that the corresponding insertion rod on the side of the slide plate 55 is disengaged from the corresponding insertion hole 52, and the fixed limit on the U-shaped seat 4 is released.

[0044] Rotate the second screw 47 downwards, causing it to descend along the screw hole 46 on the second ear plate 45. This causes the adjusting part 40 to descend, disengaging the guide ball 49 from the bottom guide rod. Under the elastic force of the corresponding return spring 51, the ball 49 presses against the circumferential side of the guide rod above the bottom guide rod. Each group of guide balls 49 is squeezed by the corresponding guide rod and slides away from the square column 36, thereby achieving equal spacing adjustment of each group of U-shaped seats 4. After adjustment, release the ear 57. Under the elastic return force of the compression spring 60, the corresponding insertion rod is inserted into the corresponding insertion hole 52, completing the fixed positioning of the U-shaped seat 4. This adapts to the insertion of the U-shaped steel bar 27 at different positions on the formwork-free 24, improving the practicality of the device.

[0045] In the initial state, the connecting spring 31 is in normal condition, and the gear 20 is disengaged from the corresponding toothed plate 22. Under the elastic force of the arc spring 19, the arc plate 18 and the rotating shaft 14 are rotated, so that the second half connecting post 16 at the end of the pressure rod 15 on the circumferential side of the rotating shaft 14 presses on the first half connecting post 10. The first half connecting post 10 and the second half connecting post 16 are coaxially arranged.

[0046] The U-shaped steel bars 27 are inserted into the corresponding U-shaped seats 4 along the corresponding U-shaped grooves 26 in sequence. When the U-shaped steel bars 27 contact the pressure rod 15, they squeeze the pressure rod 15 to make it rotate, thereby driving the arc plate 18 to slide inside the arc tube 17. The corresponding arc spring 19 is compressed. When the U-shaped steel bars 27 are separated from the pressure rod 15, under the elastic restoring force of the arc spring 19, the arc plate 18 and the rotating shaft 14 are driven to rotate, so that the second half connecting column 16 at the end of the pressure rod 15 on the circumference of the rotating shaft 14 presses on the first half connecting column 10, thus completing the reset.

[0047] Pressing the slide bar 11 inward causes the corresponding first half-connecting column 10 to press against the adjacent second half-connecting column 16, thereby causing each set of first sliding sleeves 8 and second sliding sleeves 9 to slide synchronously along the corresponding L-shaped plate 5 towards the support plate 2, until each set of pressure rods 15 presses against the corresponding U-shaped steel bar 27, and the corresponding connecting spring 31 is compressed, so that each set of U-shaped steel bars 27 is clamped and fixed in the corresponding U-shaped groove 26. At this time, the second threaded tube 64 is coaxially set with the corresponding slide bar 11. Rotating the second threaded tube 64 causes it to rotate and advance in the direction of the corresponding slide bar 11 until the slide bar 11 is inserted into the second threaded tube 64, completing the synchronous fixing, clamping and limiting of each set of U-shaped steel bars 27.

[0048] Rotating the first screw 29 drives the support plate 2 to move along the guide rod 30 toward the square of the inclined support plate 25 where the formwork 24 is placed, until each group of clamped and fixed U-shaped steel bars 27 are simultaneously inserted into the formwork 24, ensuring that the binding position of each group of U-shaped steel bars 27 is accurate, improving the quality of the formwork 24 with steel bars, completing the assembly of the formwork 24 with steel bars, lifting the tooling with the formwork 24 fixed, placing it on a multi-layer flatbed trolley, and directly transporting it to the production line for use, thereby improving the production efficiency of PC components.

[0049] When it is necessary to separate the tooling from the rebar-supported formwork module, release the limiting position of the sliding rod 11 corresponding to the second threaded tube 64, pull the guide tube 13 outward, thereby causing the second half-connecting column 16 at the end of the corresponding pressure rod 15 to press the corresponding first half-connecting column 10, so that each set of pressure rods 15 moves away from the corresponding U-shaped rebar 27 simultaneously. When the gear 20 moves to mesh with the corresponding toothed plate 22, continue to pull the guide tube 13 outward, the second sliding part 7 continues to slide, the corresponding connecting spring 31 is stretched, the gear 20 rotates when it meshes with the toothed plate 22 during the forward movement, thereby driving the rotating shaft 14 to rotate together with the pressure rod 15, so that the second half-connecting column 16 at the end of the pressure rod 15 rotates and disengages from the first half-connecting column 10, thereby opening the corresponding U-shaped seat 4, allowing the corresponding U-shaped rebar 27 to move freely in and out, releasing the fixed clamping limitation on each set of U-shaped rebar 27, and rotating the first screw 29 in the opposite direction to make the support plate 2 slide away from the formwork-supported 24, and the rebar-supported formwork module can be directly removed. The operation is simple and easy to use.

[0050] A method for using a tooling for the production of concrete PC components includes the following steps: T1. Insert each group of U-shaped steel bars 27 into the corresponding U-shaped seat 4 in sequence, push the outermost slide rod 11, and drive each group of first sliding parts 6 and second sliding parts 7 to move synchronously toward the support plate 2, so that each group of pressure rods 15 synchronously presses the corresponding U-shaped steel bars 27. At this time, rotate the second threaded tube 64 to rotate forward until the corresponding slide rod 11 is inserted into the second threaded tube 64, thus completing the synchronous and stable clamping of each group of U-shaped steel bars 27.

[0051] T2. Control the support plate 2, which is clamped and fixed with U-shaped steel bars 27, to slide towards the non-removable mold 24 until each group of U-shaped steel bars 27 is inserted into the non-removable mold 24 at the same time. Then, fix each group of U-shaped steel bars 27 on the non-removable mold 24 with steel wire to complete the assembly of the non-removable mold module with steel bars. Lift the tooling with the non-removable mold module fixed, place it on a multi-layer flatbed trolley, and transport it directly to the production line for use.
