Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a combined mould for casting a structural column. Background Art

[0002] In order to significantly improve the earthquake resistance and overall stability of the structure, modern architectural practice places special emphasis on setting up structural columns at key locations - these locations include the four corners of the exterior wall, the intersection of the horizontal wall and the longitudinal exterior wall at the floor dislocation, the sides of large openings, and the connection between the interior and exterior walls of the open space. By arranging structural columns, not only can the structural properties of the wall be strengthened, but it can also effectively resist the impact of natural disasters such as earthquakes, ensuring the safety and stability of the building under various conditions.

[0003] In the construction of structural columns, especially for those with significant height, it is difficult to ensure the overall density of the structural columns by pouring and vibrating at one time. Therefore, multiple pouring ports are set and bell-mouth templates are fixed at the pouring port positions. During construction, the bell-mouth templates are generally filled with concrete, and then the templates at the bell-mouth position are removed and the excess concrete is removed.

[0004] However, the above-mentioned structural column combined mold still has the following defects during use:

[0005] (1) Since the staff needs to strictly grasp the timing of removing the formwork at the bell mouth position (removing it too early will affect the overall hardening effect of the structural column, and it is easy to damage the structural column and affect the flatness; removing it too late will make the concrete too hard to remove), it is necessary to remove the bell mouth formwork within an appropriate time period and chisel off the concrete at the bell mouth position, which is labor-intensive and material-intensive, and prolongs the construction period.

[0006] (2) After the excess concrete is removed, the formwork needs to be used again to seal the pouring opening to ensure the overall support effect of the structural column, which makes the entire construction process cumbersome and the work efficiency low. Summary of the invention

[0007] In order to overcome the above technical problems, the purpose of the present invention is to provide a combined mold for casting structural columns, which is used to solve the problem proposed in the above background technology that the existing structural columns are provided with a bell-mouth structure to ensure the compact casting effect of the structural columns, but the use is cumbersome and the construction efficiency is low.

[0017] Preferably, a sealing mechanism is provided on the front template, and at least two pouring ports are provided on the front template, and the sealing mechanism is used to seal the pouring ports except the top of the structural column; the sealing mechanism includes a sealing plate, a rotating mechanism and a limiting mechanism; the sealing plate is hinged at the pouring port position; the bell-mouth template is slidably connected to the front template, and the rotating mechanism is used to drive the sealing plate to rotate; the limiting mechanism is used to keep the sealing plate and the front template in a flat state; when the bell-mouth template slides upward from the bottom of the sealing plate to approach the sealing plate, the sealing plate is driven to rotate upward by the rotating mechanism.

[0022] Beneficial effects of the present invention:

[0023] 1. By setting an isolation mechanism, the bell-mouth template and the casting cavity are separated by a first partition; when the first partition is rotated upward to be parallel to the front template, the concrete between the first partition and the casting cavity is squeezed, so that the excess concrete is introduced into the bell-mouth template through the flow hole, and then the first partition is maintained in a parallel state with the front template through the locking mechanism; then the flow hole is blocked by the blocking mechanism, and when blocking, part of the concrete is squeezed into the casting cavity, so that the bell-mouth template is completely isolated from the casting cavity, and the density of the concrete in the casting cavity is ensured; while ensuring the density effect in the casting cavity, the bell-mouth template is completely isolated from the casting cavity, and the concrete in the bell-mouth template can be directly cleaned at this time, so that the bell-mouth concrete chiseling work in the later stage can be avoided;

[0024] 2. By setting a first linkage mechanism and a second linkage mechanism, the first linkage mechanism drives the baffle to slide along a direction perpendicular to the axis of the flow hole to block the flow hole, and drives the baffle to slide along the axis of the flow hole into the casting cavity until one side of the baffle coincides with the side of the first baffle close to the casting cavity, that is, at this time, the first baffle and the baffle form a flat surface, so as to squeeze the casting cavity, make the concrete dense, and ensure the flatness of the structural column;

[0025] 3. By setting up a sealing mechanism, in the process of pushing the bell-mouth template upward to align with the upper pouring port, the rotating mechanism can drive the sealing plate to rotate upward to seal the pouring port. After the sealing plate seals the pouring port, as the bell-mouth template continues to move upward, the limiting mechanism limits the rotation of the sealing plate, so that the pouring port is automatically sealed as the bell-mouth template moves upward, thereby improving ease of use.

DETAILED DESCRIPTION

[0037] 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.

[0038] like Figure 1-9 As shown, a combined mold for casting a structural column, such as Figure 1-3 and Figure 6As shown, it includes a front template 1 and two side templates 2 arranged on both sides of the front template 1, and a casting cavity for forming a structural column is surrounded between the front template 1 and the two side templates 2; a casting port 3 connected to the casting cavity is arranged on the front template 1, a bell-mouth template 4 is arranged on the casting port 3, and an isolation mechanism 5 for isolating the bell-mouth template 4 from the casting cavity is arranged on the front template 1; the isolation mechanism 5 includes a first partition 51, and the first partition 51 is hinged at the position of the casting port 3; when the first partition 51 rotates upward and is parallel to the front template 1, The first partition 51 blocks the pouring port 3 to isolate the bell-mouth formwork 4 from the pouring cavity; and when the first partition 51 rotates upward, excess concrete between the first partition 51 and the pouring cavity is allowed to be discharged through the flow hole 52; a sealing mechanism 53, the sealing mechanism 53 is used to block the flow hole 52 when the first partition 51 rotates upward and is parallel to the front formwork 1, so as to isolate the bell-mouth formwork 4 from the pouring cavity; a locking mechanism 54, the locking mechanism 54 is used to keep the first partition 51 parallel to the front formwork 1 to block the pouring port 3.

[0039] It should be noted that when it is necessary to pour concrete from the pouring port 3 at the top of the combined formwork, the bell-mouth formwork 4 is slid upward and maintained at the pouring port 3, and then the first partition 51 is rotated and opened, so that the first partition 51 is tilted in the bell-mouth formwork 4. At this time, the position of the bell-mouth formwork 4 can be adjusted to push the first partition 51 to rotate, so as to adjust the inclination of the first partition 51. When the concrete is introduced into the bell-mouth formwork 4, it is tilted and guided by the first partition 51 to control the speed of concrete pouring and falling, so as to prevent the concrete from segregating. The first partition 51 with adjustable inclination does not affect the vibrator inserted into the pouring cavity after pouring to compact the concrete. The vibrator is a prior art, which is not drawn in the figure and will not be described in detail.

[0040] After the concrete is compacted, the first partition 51 is pushed to rotate upward so that the first partition 51 rotates to be parallel to the front template 1, and then the bell-mouth template 4 is separated from the pouring cavity by the first partition 51; it can be understood that the first partition 51 can be driven to rotate manually or mechanically, such as an electric telescopic rod, as long as the first partition 51 can be driven to rotate to be parallel to the front template 1;

[0041] When the first partition 51 rotates upward to be parallel to the front template 1, the concrete between the first partition 51 and the casting cavity is squeezed, so that the excess concrete is introduced into the bell-mouth template 4 through the flow hole 52, and then the first partition 51 is maintained in a parallel state with the front template 1 through the locking mechanism 54; then the flow hole 52 is blocked by the blocking mechanism 53, and when blocked, part of the concrete is squeezed into the casting cavity, so that the bell-mouth template 4 is completely isolated from the casting cavity, and the density of the concrete in the casting cavity is ensured;

[0042] The present application drives the first partition 51 to isolate the bell-mouth formwork 4 from the casting cavity, so that the bell-mouth formwork 4 can be directly removed without waiting for the concrete to harden, which can eliminate the concrete chiseling work, improve work efficiency, and ensure the flatness of the structural column forming; when the first partition 51 is driven to rotate upward to squeeze the concrete, due to the poor fluidity of the concrete, the flow hole 52 is set so that the concrete can be directly discharged from the flow hole 52 when squeezed, and the number of the flow holes 52 can be set to be multiple, as long as the casting cavity can be squeezed by the first partition 51, the compaction effect of the concrete in the casting cavity is guaranteed, and the excess concrete can be discharged from the flow hole 52; when the concrete is discharged from the flow hole 52, the flow hole 52 is blocked by the blocking mechanism 53, so that the compaction effect in the casting cavity is guaranteed, and the bell-mouth formwork 4 is completely isolated from the casting cavity. At this time, the concrete in the bell-mouth formwork 4 can be directly cleaned, and the subsequent bell-mouth concrete chiseling work can be eliminated.

[0043] like Figure 2-4 As shown, the blocking mechanism 53 includes a baffle 531 adapted to the circulation hole 52 and a first driving mechanism 532 for driving the baffle 531 to move; the first driving mechanism 532 is used to first drive the baffle 531 to slide along a direction perpendicular to the axis of the circulation hole 52 to block the circulation hole 52, and then drive the baffle 531 to slide along the direction of the axis of the circulation hole 52 to drive one side of the baffle 531 to coincide with a side of the first partition plate 51 close to the casting cavity.

[0044] It should be noted that the baffle 531 is driven by the first driving mechanism 532 to slide along the direction perpendicular to the axis of the flow hole 52 to block the flow hole 52. A chamfer is provided on one side of the baffle 531 to reduce the thickness of the contact position between one side of the baffle 531 and the flow hole 52, so as to prevent the thickness between the baffle 531 and the flow hole 52 from being too thick, causing the concrete to be clamped between the baffle 531 and the flow hole 52, thereby affecting the sealing effect of the flow hole 52; the chamfer is provided on the side away from the casting cavity, so when the flow hole 52 is blocked, the excess concrete can be pushed into the bell-mouth template 4, so as to prevent excessive concrete from being squeezed into the casting cavity;

[0045] After the baffle 531 moves to seal the flow hole 52 , the first driving mechanism 532 drives the flow hole 52 to approach the casting cavity, and squeezes the concrete in the flow hole 52 to ensure that the concrete at the position of the flow hole 52 is dense.

[0046] like Figure 3-5 As shown, the first driving mechanism 532 includes a first bevel gear 5321, a second bevel gear 5322, a first linkage mechanism 533 and a second linkage mechanism 534; the second bevel gear 5322 is rotatably connected to the first partition plate 51 (as shown in FIG. Figure 2As shown in the figure, the first bevel gear 5321 is arranged on the first linkage mechanism 533, and the first bevel gear 5321 is meshed with the second bevel gear 5322; the first linkage mechanism 533 is used to drive the baffle 531 to slide in a direction perpendicular to the axis of the flow hole 52 to block the flow hole 52; the second linkage mechanism 534 is used to drive the baffle 531 to slide in the direction of the axis of the flow hole 52 to drive one side of the baffle 531 to coincide with the side of the first partition 51 close to the casting cavity; the second bevel gear 5322 is formed with a hexagonal hole 5323 adapted for use with a hexagonal wrench; the second bevel gear 5322 is driven to rotate by the hexagonal wrench to drive the first bevel gear 5321 to rotate; the hexagonal wrench is a prior art, which is not shown in the figure and will not be described in detail.

[0047] It should be noted that when the convection hole 52 needs to be sealed, the hexagonal wrench drives the second bevel gear 5322 to rotate through the hexagonal hole 5323, and the first bevel gear 5321 is driven to rotate through the second bevel gear 5322, and the first linkage mechanism 533 is driven to move through the first bevel gear 5321, and the second linkage mechanism 534 is driven to move through the first linkage mechanism 533, and the baffle 531 is driven by the first linkage mechanism 533 to slide in a direction perpendicular to the axis of the convection hole 52 to block the convection hole 52, and the baffle 531 is driven to slide into the casting cavity along the direction of the axis of the convection hole 52 until one side of the baffle 531 coincides with the side of the first partition 51 close to the casting cavity, that is, at this time the first partition 51 and the baffle 531 form a flat surface, which realizes the extrusion of the casting cavity, making the concrete dense while ensuring the flatness of the structural column forming.

[0048] like Figure 5 As shown, the first linkage mechanism 533 includes a bidirectional screw rod 5331, a slide seat 5332 and a first partition plate 51 (such as Figure 2 The bidirectional screw rod 5331 is rotatably connected to the first partition plate 51, the slide seat 5332 is fixed to the connecting plate 5333, and the slide seat 5332 is threadedly sleeved on the bidirectional screw rod 5331.

[0049] It should be noted that when the first bevel gear 5321 is driven to rotate, the bidirectional screw rod 5331 is driven to rotate, the bidirectional screw rod 5331 drives the slide 5332 to move, the two slides 5332 drive the two connecting plates 5333 to move, and then the baffles 531 are driven to move closer to or farther away from each other. When the two baffles 531 are close to each other, the baffles 531 move the convection holes 52 (such as Figure 3 When the two baffles 531 are moved away from each other, the flow hole 52 is opened to discharge the concrete.

[0050] like Figure 3 and 5-6, the second linkage mechanism 534 includes a pair of first rotating rods 5341 and a pair of second rotating rods 5342 arranged in parallel; the two ends of one of the first rotating rods 5341 are respectively hinged to one end of the pair of second rotating rods 5342, and the two ends of the other first rotating rod 5341 are respectively hinged to the other end of the pair of second rotating rods 5342; the pair of first rotating rods 5341 and the pair of second rotating rods 5342 form a parallelogram four-bar structure, and one of the first rotating rods 5341 is fixed to the connecting plate 5333, and one end of the other first rotating rod 5341 is hinged to the baffle 531.

[0051] It should be noted that when the first linkage mechanism 533 drives the baffle 531 to move, the baffle 531 slides in a straight line in the first partition 51. Since the baffle 531 is restricted by the slide groove and cannot move in the vertical direction of the first partition 51, the second rotating rod 5342 cannot rotate at this time. Therefore, the pair of first rotating rods 5341 and the pair of second rotating rods 5342 maintain a parallelogram of a certain shape and push the baffle 531 to move until the baffle 531 moves into the flow hole 52 to block the flow hole 52. At this time, the baffle 531 moves from the first baffle 51 to the second baffle 51. It moves out from a partition 51 without being restricted by the slide groove, and because one side of the baffle 531 conflicts with the circulation hole 52, as the connecting plate 5333 continues to move, it drives the first rotating rod 5341 to move, causing the second rotating rod 5342 to rotate, pushing the baffle 531 to slide in the circulation hole 52 until one side of the baffle 531 coincides with one side of the first partition 51, thereby sealing the circulation hole 52 and squeezing the casting cavity. The concrete at the position of the circulation hole 52 in the casting cavity is dense, and the cast structural column is guaranteed to have good flatness.

[0052] like Figure 2-3 and Figure 6-7 As shown, the locking mechanism 54 includes a positioning block 541 and a hexagonal shaft 542; the hexagonal shaft 542 is arranged at the end of the bidirectional screw rod 5331, the positioning block 541 is adapted to be inserted into the hexagonal shaft 542, and the positioning block 541 is threadedly connected in the first partition 51; when the bidirectional screw rod 5331 rotates, the positioning block 541 is driven to rotate through the hexagonal shaft 542 to drive the positioning block 541 to slide toward the outside of the first partition 51 or to shrink toward the inside of the first partition 51; when the first partition 51 rotates upward and is parallel to the front template 1, and the positioning block 541 slides toward the outside of the first partition 51, the positioning block 541 is inserted into the positioning hole 544; a spring 543 is sleeved on the hexagonal shaft 542, and one end of the spring 543 is connected to the first partition 51, and the other end of the spring 543 is connected to the positioning block 541.

[0053] It should be noted that when the first partition 51 is driven to rotate upward and to be parallel to the front template 1, the baffle 531 is driven to block the flow hole 52, which drives the bidirectional screw 5331 to rotate. At this time, the bidirectional screw 5331 drives the hexagonal shaft 542 to rotate, and the positioning block 541 is driven to rotate through the hexagonal shaft 542, so that the positioning block 541 is plugged into the positioning hole 544, thereby locking the state of the first partition 51; and at this time, the spring 543 is stretched under force, which improves the spiral stability between the positioning block 541 and the first partition 51, and ensures a good plug-in locking effect;

[0054] One end of the positioning block 541 is a dome structure, so that when the first partition 51 is slightly offset, the positioning block 541 can still be inserted into the positioning hole 544. When the positioning block 541 is fully inserted into the positioning hole 544, the rotation position of the first partition 51 can be corrected to ensure the flatness of the structural column.

[0055] like Figure 1-2 and Figure 8 As shown, a sealing mechanism 6 is provided on the front template 1, and at least two pouring ports 3 are provided on the front template 1. The sealing mechanism 6 is used to seal the pouring ports 3 except the top of the structural column; the sealing mechanism 6 includes a sealing plate 61, a rotating mechanism 62 and a limiting mechanism 63; the sealing plate 61 is hinged at the pouring port 3; the bell-mouth template 4 is slidably connected to the front template 1, and the rotating mechanism 62 is used to drive the sealing plate 61 to rotate; the limiting mechanism 63 is used to keep the sealing plate 61 and the front template 1 in a flat state; when the bell-mouth template 4 slides upward from the bottom of the sealing plate 61 to approach the sealing plate 61, the sealing plate 61 is driven to rotate upward by the rotating mechanism 62.

[0056] It should be noted that when the structural column is formed to a high height and needs to be poured in steps, it is necessary to pour concrete on the lower pouring port first, and the bell-mouth template 4 can be pushed to move upward so that the bell-mouth template 4 moves to the position of the lower pouring port 3, and then the sealing plate 61 is rotated to open, and when concrete is introduced into the bell-mouth template 4, it is guided by the sealing plate 61. The height of the bell-mouth template 4 can also be adjusted, and then the rotation and tilting amplitude of the sealing plate 61 can be adjusted to adjust the concrete pouring and falling speed to prevent segregation. When pouring is close to the pouring port 3, the pouring can be stopped, and then the vibrator is used to compact the concrete;

[0057] Then the bell-mouth template 4 can be pushed upward, so that the rotating mechanism 62 can drive the sealing plate 61 to rotate upward to block the pouring port 3. After the sealing plate 61 blocks the pouring port 3, as the bell-mouth template 4 continues to move upward, the limiting mechanism 63 limits the rotation of the sealing plate 61, so that the pouring port 3 is automatically blocked as the bell-mouth template 4 moves upward, thereby improving ease of use.

[0058] like Figure 8-9 As shown, the rotating mechanism 62 includes a first spur gear 621, and the first spur gear 621 is arranged between the sealing plate 61 and the front template 1 (as shown in FIG. Figure 1 At the hinged position (as shown), the bell-mouth template 4 is provided with a tooth groove 622 adapted to the first spur gear 621; when the bell-mouth template 4 moves upward so that the tooth groove 622 is engaged with the first spur gear 621, the first spur gear 621 is driven to rotate, and the sealing plate 61 is driven to rotate upward through the first spur gear 621; the bell-mouth template 4 is provided with a positioning mechanism for locking the position between the bell-mouth template 4 and the front template 1;

[0059] It can be understood that the positioning mechanism is a prior art, such as Figure 1 As shown in the figure, a threaded hole can be provided on the front template 1 so that the bell-mouth template 4 is connected to the front template 1 by bolts; in order to improve the convenience of movement, a ratchet mechanism can be provided. The ratchet mechanism is a prior art and is not drawn in the figure. It allows 4 to slide upward. When the bell-mouth template 4 falls, the ratchet is engaged by the pawl to prevent the bell-mouth template 4 from falling, thereby locking the position of the bell-mouth template 4. When the height of the bell-mouth template 4 needs to be adjusted downward, the pawl can be separated from the ratchet to push the bell-mouth template 4 down.

[0060] It should be noted that after the pouring of concrete in the pouring cavity at the lower pouring port 3 is completed, the bell-mouth template 4 is pushed to slide upward, so that the tooth groove 622 drives the first spur gear 621 to rotate, and the sealing plate 61 is driven by the first spur gear 621 to rotate to seal the pouring port 3. When the sealing plate 61 rotates to be parallel to the front template 1, as the tooth groove 622 moves upward, the limiting mechanism 63 can be driven to lock the rotation state of the sealing plate 61.

[0061] like Figure 8-9 As shown, the limiting mechanism 63 includes a slide plate 631 and a second driving mechanism 632; the slide plate 631 is slidably connected to the pouring port 3 (such as Figure 1 ), the second driving mechanism 632 is used to drive the slide plate 631 to move; when the second driving mechanism 632 drives the slide plate 631 to move downward, the slide plate 631 contacts the sealing plate 61 to prevent the sealing plate 61 from rotating downward; the second driving mechanism 632 includes a tooth plate 6321 arranged on the slide plate 631 and a tooth plate 6321 rotatably connected to the front template 1 (as shown in FIG. Figure 1 As shown in the figure, the tooth plate 6321 is meshed with the second spur gear 6322, and the tooth groove 622 is matched with the second spur gear 6322; when the bell-mouth template 4 moves upward, the tooth groove 622 is meshed with the second spur gear 6322, which drives the second spur gear 6322 to rotate, and then drives the tooth plate 6321 to move, so as to drive the slide plate 631 to move downward.

[0062] It should be noted that when it rotates to a state parallel to the front template 1, as the bell-mouth template 4 continues to slide upward, the tooth groove 622 is driven to separate from the first spur gear 621, and the tooth groove 622 is meshed with the second spur gear 6322. As the bell-mouth template 4 continues to move, the second spur gear 6322 is pushed to rotate through the tooth groove 622, and the tooth plate 6321 is driven to move through the second spur gear 6322, thereby driving the slide plate 631 to descend until the slide plate 631 descends and is misaligned with the sealing plate 61, thereby preventing the sealing plate 61 from rotating, thereby achieving clamping and locking of the sealing plate 61. It can be understood that when the sealing plate 61 slides in the front template 1, there is a certain friction between the sealing plate 61 and the front template 1. Therefore, when the sealing plate 61 is contracted in the front template 1, the friction force can ensure that the sealing plate 61 is in a contracted state, and when the second spur gear 6322 is driven to rotate, the thrust on the sealing plate 61 is greater than the friction force, thereby pushing the sealing plate 61 to rise and fall normally.
