Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated concrete parts, and more particularly to a tool for producing prefabricated concrete components and a method for using the tool. Background Art

[0002] In the current production of PC components, most require reinforcement, and the surface of the reinforcement needs to be roughened to improve adhesion to the post-cast concrete. Existing methods rely on drilling holes in the side molds, allowing the rebar to extend through the holes, applying a retarder to the side molds, and then washing away the mortar on the retarder-coated side after the molds are removed, exposing the aggregate to achieve the roughened surface. This method is complex and costly to produce.

[0003] After searching, an auxiliary fixing device and special tooling for PC component production with announcement number CN112223221B were found. The auxiliary fixing device is equipped with a fixed clamping plate, a movable clamping plate and a clamping guide rod, and uses a quick clamping device that pushes the connected clamping guide rod to drive the clamping guide rod forward and lock the steel bars, thereby fixing the entire row of steel bars on the formwork-free module, so that the formwork-free module with steel bars and the device form a rigid integral component; the special tooling has a simple structure and is easy to use, which improves the application efficiency of formwork-free in the production of prefabricated building components.

[0004] The above-mentioned auxiliary fixing device and special tooling for PC component production are to first pass the open end of the U-shaped steel bar through the non-removal form and tie it together with the non-removal form through wire to form a non-removal form module with steel bars, and then place the auxiliary fixing device on the non-removal form module with steel bars from above. However, each group of U-shaped steel bars is first passed through the non-removal form and tied with wire in turn. During this process, the positioning of the bundling position of each group of U-shaped steel bars is prone to errors, which reduces the quality of the non-removal form module with steel bars and affects subsequent production.

[0038] Both ends of the support plate 2 are provided with lifting grooves 39; an adjusting part 40 is slidably arranged between the two lifting grooves 39; the adjusting 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 plate 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 provided on the surface of the second ear plate 45; a second screw rod 47 that is screwed to the screw hole 46 and is slidably arranged on 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; a plurality of guide parts 50 are evenly fixed to the bottom surface of the cover plate 41; the guide parts 50 are composed of guide rods with decreasing outer diameters from top to bottom; the connections between adjacent guide rods are chamfered; a return spring 51 is fixedly connected between the connecting rod 38 and the adjacent guide tube 13, and between the sliding rod 11 and the adjacent guide tube 13.

[0040] A socket 52 is provided on the side of the U-shaped seat 4; a mounting groove 53 is provided on the side of the support plate 2; a positioning portion 54 is slidingly provided inside the mounting groove 53; the positioning portion 54 includes a slide plate 55 that slides with the mounting groove 53; a plurality of plug-in portions 56 are evenly fixed on the side of the slide plate 55; the plug-in portion 56 is composed of a plurality of plug rods; the socket 52 is plugged into and engaged with the corresponding plug rods.

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

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

[0043] Working principle of the second embodiment: In the initial state, under the elastic force of each group of return springs 51, the guide balls 49 on each group of U-shaped seats 4 are tightly placed on 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 extrusion 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, thereby releasing the fixed limit of the U-shaped seat 4.

[0044] The second screw rod 47 is turned downward so that it rotates and descends along the screw hole 46 on the second ear plate 45, thereby driving the adjusting part 40 to descend, so that the guide ball 49 disengages from the lowest guide rod and is pressed against the peripheral side of the guide rod above the lowest guide rod under the elastic force of the corresponding return spring 51. Each group of guide balls 49 is squeezed by the corresponding guide rod and slides in the direction away from the square column 36, thereby realizing equal spacing adjustment of each group of U-shaped seats 4. After the adjustment is completed, the ear seat 57 is released, and under the elastic return force of the extrusion spring 60, the corresponding insertion rod is driven to be inserted into the corresponding insertion hole 52, completing the fixed limit of the U-shaped seat 4, adapting to the insertion of the U-shaped steel bar 27 at different positions on the disassembly-free mold 27, and improving the practicality of the device.

[0045] In the initial state, the connecting spring 31 is in a normal state, the gear 20 is disengaged from the corresponding tooth plate 22 and is not in contact. Under the elastic force of the arc spring 19, the arc plate 18 is driven to rotate together with the rotating shaft 14, so that the second half connecting column 16 at the end of the side pressure rod 15 of the rotating shaft 14 is pressed on the first half connecting column 10, and the first half connecting column 10 and the second half connecting column 16 are arranged coaxially.

[0046] Insert the U-shaped steel bar 27 into the corresponding U-shaped seat 4 along the corresponding U-shaped groove 26 in sequence. When the U-shaped steel bar 27 contacts the pressure rod 15, the pressure rod 15 is squeezed to rotate, thereby driving the arc plate 18 to slide inside the arc tube 17, and the corresponding arc spring 19 is compressed. When the U-shaped steel bar 27 is separated from the pressure rod 15, the arc plate 18 is driven to rotate together with the rotating shaft 14 under the elastic reset force of the arc spring 19, so that the second half connecting column 16 at the end of the pressure rod 15 on the side surface of the rotating shaft 14 is pressed on the first half connecting column 10 to complete the reset.

[0047] The sliding rod 11 is pressed inward, thereby driving the corresponding first half connecting column 10 to squeeze the adjacent second half connecting column 16, and then driving each group of first sliding sleeves 8 and second sliding sleeves 9 to slide synchronously along the corresponding L-shaped plate 5 toward the direction close to the support plate 2, until each group of pressure rods 15 is pressed tightly on the corresponding U-shaped steel bar 27, and the corresponding connecting spring 31 is compressed, so that each group 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 arranged with the corresponding sliding rod 11. Rotate the second threaded tube 64 so that it rotates and advances in the direction of the corresponding sliding rod 11 until the sliding rod 11 is inserted into the second threaded tube 64, completing the synchronous fixed clamping and limiting of each group of U-shaped steel bars 27.

[0048] Rotate the first screw 29 to drive the support plate 2 to move along the guide rod 30 toward the square of the diagonal support plate 25 where the non-removal formwork 24 is placed, until each group of clamped and fixed U-shaped steel bars 27 is synchronously inserted into the non-removal formwork 24, ensuring that the bundling position of each group of U-shaped steel bars 27 is accurately positioned, thereby improving the quality of the non-removal formwork module with steel bars, completing the assembly of the non-removal formwork module with steel bars, lifting the tooling with the non-removal formwork module fixed, placing it on a multi-layer flatbed cart, 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 steel bar disassembly-free module, the limit of the sliding rod 11 corresponding to the second threaded tube 64 is released, and the guide tube 13 is pulled outward, thereby driving the second half connecting column 16 at the end of the corresponding pressure rod 15 to squeeze the corresponding first half connecting column 10, so that each group of pressure rods 15 are synchronously away from the corresponding U-shaped steel bar 27. When the gear 20 moves to engage with the corresponding tooth plate 22, the guide tube 13 is continued to be pulled outward, the second sliding part 7 continues to slide, the corresponding connecting spring 31 is stretched, and the gear 20 engages with the tooth plate 22 and rotates during the forward movement, thereby driving the rotating shaft 14 together with the pressure rod 15 to rotate, 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 making the corresponding U-shaped seat 4 open, so that the corresponding U-shaped steel bar 27 can move in and out freely, releasing the fixed clamping limit of each group of U-shaped steel bars 27, and rotating the first screw 29 in the opposite direction makes the support plate 2 slide in the direction away from the disassembly-free module 24, and the steel bar disassembly-free module can be directly taken out. It is simple to operate and easy to use.

[0050] A method for using a tool for producing concrete PC components, comprising the following steps: T1. Insert each group of U-shaped steel bars 27 into the corresponding U-shaped seat 4 in turn, push the outermost sliding rod 11, and drive each group of first sliding parts 6 and second sliding parts 7 to move synchronously toward the direction close to 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 and rotate forward until the corresponding sliding rod 11 is inserted into the second threaded tube 64, completing the synchronous and stable clamping of each group of U-shaped steel bars 27.

[0051] T2. Control the support plate 2 clamping and fixing the U-shaped steel bars 27 to slide toward the direction of the non-removal formwork 24 until each group of U-shaped steel bars 27 is synchronously inserted into the non-removal formwork 24. Then, fix each group of U-shaped steel bars 27 to the non-removal formwork 24 with steel wires to complete the assembly of the non-removal formwork module with steel bars. Lift the tooling with the non-removal formwork module, place it on a multi-layer flatbed cart, and transport it directly to the production line for use.
