[0034] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] Reference Figures 1 to 11As shown, the present invention provides a concrete rectangular inclined column casting mold trolley, including: a movable base 1, a mold frame 2, a rectangular template 3, a chain plate structure 4, and a second gap-filling plate 5.

[0037] The bottom of the mobile base 1 is provided with rollers. The mobile base 1 is provided with a hinge shaft.

[0038] As a preferred embodiment, the mobile base 1 includes two long beams 11 and two short beams. The two long beams 11 are arranged opposite each other. The two short beams are connected between the ends of the two long beams 11. The two long beams 11 and the two short beams enclose a construction opening. Rollers are mounted on each end of the long beams 11. A hinge shaft is mounted on one of the short beams. A counterweight 14 is mounted on the other short beam.

[0039] In this embodiment, a vertical threaded hole is formed at the end of the long beam 11. A locking screw 13 is screwed into the threaded hole.

[0040] In this embodiment, the length of the long beam is adjustable. Specifically, the long beam includes a square tube and an insertion rod. One end of the insertion rod is movably inserted into one end of the square tube. A short beam is connected between the square tubes of the two long beams. Another short beam is connected between the insertion rods of the two long beams. A locking piece for locking the insertion rod is installed on the square tube. The locking piece is a bolt, and a threaded locking hole is opened on the square tube. The locking piece is screwed into the threaded locking hole of the square tube and pressed against the insertion rod to lock the insertion depth of the insertion rod in the square tube.

[0041] There are two formwork frames 2. The two formwork frames 2 are arranged opposite to each other. The two formwork frames are arranged along the length direction of the short beam, that is, the two formwork frames are respectively arranged on opposite sides in the width direction of the movable base.

[0042] The bottom of the two-piece mold frame 2 is movably mounted on the hinge shaft via a sleeve. A sleeve is connected to one side of the bottom of the mold frame. The sleeve is movably mounted on the hinge shaft. The two-piece mold frame can move along the length of the hinge shaft and can be tilted up and down about the central axis of the hinge shaft. In this embodiment, the sleeve is located at a corner of the bottom of the mold frame.

[0043] Tie rods 21 with adjustable lengths are installed between opposite sides of the two mold frames 2. Tie rods 21 are fixed between one side of the two mold frames 2. Tie rods 21 are also adjustable between the second sides of the two mold frames 2. Adjusting the length of the tie rods adjusts the distance between the two mold frames.

[0044] The movable base 1 is rotatably mounted with a length-adjustable support rod 15. The support rod 15 is supported on the formwork 2 to lock the inclination angle of the formwork 2. The movable base 1 is provided with a construction opening.

[0045] In this embodiment, the support rod comprises a threaded sleeve and a core rod. The core rod is externally threaded. The core rod is screwed into the threaded sleeve. The threaded sleeve is reversibly mounted on the long beam of the mobile base via a hinged axis. After the formwork is flipped, the length of the support rod is adjusted and the support rod is supported on the formwork, so that the formwork's tilt angle adapts to the tilt angle of the concrete rectangular inclined column.

[0046] There are two rectangular templates 3. The two rectangular templates are respectively installed on the inner sides of the two mold frames 2. The upper and lower ends of the rectangular template 3 are respectively installed with first gap-filling plates 31 in an adjustable manner.

[0047] There are two chain plate structures 4. The two chain plate structures are embedded between the two rectangular templates. The two chain plate structures and the rectangular templates enclose a pouring space for pouring the middle section of the concrete rectangular inclined column.

[0048] The chain plate structure 4 includes two supports 41, a hinge plate 42 and a gear 43. The two supports 41 are respectively installed at the two ends of the pull rod 21. Gears 43 are rotatably installed on the opposite sides of the two supports 41. A gap is formed between the gear 43 and the opposite sides of the supports 41. The opposite sides of the hinge plate 42 are respectively inserted into the gap. A tooth pattern 421 is formed on the side of the hinge plate 42 facing the gear 43. The gear 43 engages with the tooth pattern 421. A scissor rod 44 supported on the middle part of the hinge plate 42 is installed in the middle part of the pull rod 21. One chain plate structure 4 is fixed between one side of the two rectangular templates 3. The two supports 41 of the other chain plate structure 4 are adjustably installed between the other sides of the two rectangular templates 3.

[0049] In the chain plate structure, the support and hinged plate combination serve as the formwork for one side of a rectangular concrete column. The rectangular formwork serves as the formwork for the other side of the column. The hinged plate is long and vertically arranged. The sides of the hinged plate are hinged to the adjacent hinged plate. The gap between the support and the gear, as well as the scissor rods, support the hinged plate at both ends and in the middle, ensuring that the hinged plate is perpendicular to the rectangular formwork surface.

[0050] After the two formwork frames 2 are flipped over, the position of the first filling plate 31 is adjusted so that the first filling plate 31 blocks the gaps between the two ends of the rectangular formwork 3 and the upper and lower floor slabs, and the second filling plate 5 blocks the gaps between the upper and lower ends of the two chain plate structures 4 and the upper and lower floor slabs respectively.

[0051] In this embodiment, the first gap-filling plate 31 is semicircular in shape. A first chute a is formed on the outer side of the rectangular template 3, extending along the wide width of the rectangular template 3. A first slider slides in the first chute a. A slide bar 311 is connected to the first slider. The slide bar 311 defines a second chute extending along the length of the rectangular template 3. A second slider slides in the second chute. The second slider is rotatably mounted to the first gap-filling plate 31 via a rotating shaft. Accordingly, a locking member for locking the second slider is mounted on the first gap-filling plate. Similarly, a locking member for locking the first chute is mounted on the first slider.

[0052] See Figures 6 to 9 The accompanying drawings show the process of the first gap-filling plate at the lower end of the rectangular template from the initial state to blocking the gaps between the two ends of the rectangular template 3 and the upper and lower floor slabs.

[0053] See Figure 2 and Figure 3 As shown, the tie rod 21 includes two first rod segments 211 and a second rod segment 212. One end of each of the two first rod segments 211 is mounted to the two mold frames 2. The two ends of a second rod segment 212 are adjustably mounted to the other ends of the two first rod segments 211. The two supports 41 of the chain plate structure 4 are mounted to the two first rod segments 211.

[0054] Specifically, the second rod section is formed with a strip hole. The strip hole is arranged along the length direction of the second rod section. The first rod section is provided with a through hole. The second rod section is arranged in the same direction as the first rod section. One end of the second rod section is overlapped with one end of the first rod section, and the through hole is aligned with the strip hole. A tension screw is passed through the through hole and the strip hole. The tension screw is slid into the strip hole. Screw fittings are installed at both ends of the tension screw. The screw fittings at both ends of the tension screw are respectively pressed against the outside of the first rod section and the outside of the second rod section to lock the length of the pull rod.

[0055] Continue reading Figure 2 and Figure 3 As shown, the scissor rod is used to support the connecting plate. Specifically, the scissor rod 44 includes multiple fork rod segments. The multiple fork rod segments are arranged along the length of the rectangular template. Among them, the fork rod segment includes two hinged arms 441. The middle portions of the two hinged arms 441 are hinged together. One end of each hinged arm 441 is pivotally connected to the other end of the two hinged arms 441 of the adjacent fork rod segment.

[0056] In this embodiment, see Figure 3 As shown, the first rod section 211 is connected to a guide rod 443. The guide rod 443 defines a third slot extending along the length of the hinge plate 42. One end of each of the two hinged arms 441 is pivotally connected to the other end of each of the two hinged arms 441 of the adjacent fork rod segment via a pivot 442. The pivots 442 on opposite sides of the scissor lever 44 slide in the third slot.

[0057] See Figure 2 and Figure 4 As shown, a clamping plate 411 is connected to the opposite side of the support 41. The clamping plate 411 is installed on the outer side of the rectangular template 3 by bolts 412.

[0058] In this embodiment, a chain plate structure is adjustably mounted between two rectangular templates. The support plate has a waist-shaped hole formed in the clamping plate. The waist-shaped hole runs along the width of the rectangular template. Bolts are movably inserted through the waist-shaped hole and screwed into threaded holes on the outside of the rectangular template. The clamping plate is locked to the rectangular template by turning the bolts. Adjusting the position of the bolts in the waist-shaped hole further adjusts the distance between the two chain plate structures.

[0059] See Figure 4 As shown, the two supports 41 extend toward each other on one side away from the pull rod 21 to form a guide rib 413. The side of the guide rib 413 facing the gear 43 forms an arcuate side surface, the curvature of the arcuate side surface being adapted to the curvature of the circumferential surface of the gear 43.

[0060] The present invention provides a construction method for a concrete rectangular inclined column casting mold trolley, comprising the following steps:

[0061] S1. See Figure 5 and Figure 6 , move the mobile base 1 to the pouring position b of the concrete rectangular inclined column so that the construction opening of the mobile base 1 is aligned with the lower end of the pouring position.

[0062] S2. Adjust the first distance between the two rectangular formworks 3 by adjusting the length of the tie rod 21, and adjust the second distance between the two chain plate structures 4 by adjusting the position of the tie rod 21 between the second sides of the two formwork frames 2. The first distance and the second distance are respectively adapted to the length and width of the concrete rectangular inclined columns. A casting space is enclosed between the two rectangular formworks 3 and the two chain plate structures 4.

[0063] S3, see Figure 7 , flip the two pieces of formwork 2 so that the pouring space coincides with the pouring position.

[0064] S4. Continue reading Figure 7 , support the support rod 15 on the mold frame 2 to lock the inclination angle of the mold frame 2.

[0065] S5. See Figures 7 to 11 , adjust the positions of the first gap-filling plates 31 at the upper and lower ends of the rectangular template 3 so that the first gap-filling plates 31 block the gaps between the two ends of the rectangular template 3 and the upper and lower floor slabs.

[0066] S6. See Figure 3The second filling plate 5 is used to seal the gaps between the upper and lower ends of the two chain plate structures 4 and the upper and lower floor slabs 6 respectively. The second filling plate 5 and the first filling plate 31 are used to enclose an extension space, and the extension space is connected to the pouring space to form a pouring cavity for the concrete rectangular inclined column.

[0067] The present invention utilizes rollers on a movable base to facilitate mobility. The formwork and counterweights on the movable base maintain balance and stability. The formwork's inclination is adjusted by rotating the hinge shaft and sleeve, and support rods are used to reinforce and lock the formwork. The length of the concrete rectangular oblique column is adjusted by the length of the pull rod, and the width of the concrete rectangular oblique column is adjusted by adjusting the distance between the two chain plate structures. The gaps around the top and bottom of the rectangular formwork are filled with first and second gap-filling plates, achieving the desired effect of fully enclosing the cast-in-place concrete rectangular oblique column.
