Description

Technical Field

[0001] The invention relates to the technical field of building templates, and in particular to an adjustable building template supporting structure. Background Art

[0002] When pouring shear walls, the current construction process is to fix two steel molds on both sides of the wall reinforcement, and then close the molds for reinforcement after positioning. Since the mass of mortar is large during the pouring process, reinforcement is particularly critical. The current reinforcement method of shear walls is mainly through diagonal braces and cross bars. Its main purpose is to prevent mold expansion. Although the combination of the two methods can effectively prevent mold running or expansion, the overall reinforcement work time is long and the overall work efficiency is low, which is far from meeting the construction progress requirements.

[0003] In this regard, the Chinese utility model patent application number 201720509102.5 discloses "a building formwork support structure". The support formwork is hoisted to both sides of the wall reinforcement, and then the screw rod is passed through the support formwork and the limit plate and screwed and fixed with the nut to perform preliminary positioning of the support formwork. The positioning plate is then unfolded outward as a whole and fixed to the concrete floor. The end of the screw rod is then inserted into the diagonal support rod, and the verticality of the support formwork is adjusted through the positioning seat. Since the clamping reinforcement of the traditional support formwork is combined with the diagonal support reinforcement, the overall reinforcement strength can be effectively improved.

[0004] However, there are still some problems when using the above patent: by combining two symmetrical support formworks together with bolts, and then adjusting the verticality of the support formworks through positioning seats, and by combining clamping reinforcement with diagonal bracing reinforcement into one, although the overall work efficiency is improved to a certain extent, when using it, it is necessary to first combine the bolts and then adjust multiple positioning seats, and the efficiency is still not fast enough. In this regard, an adjustable building formwork support structure is provided to further improve the efficiency. Summary of the Invention

[0041] refer to Figures 1 to 11 As shown, an adjustable building template support structure includes two L-shaped support bases 1,

[0042] The two L-shaped support seats 1 are detachably connected by a connecting device 7, and the upper parts of the vertical seats of the two L-shaped support seats 1 are movably connected with a supporting mechanism 2, and the first side walls of the vertical seats of the two L-shaped support seats 1 are installed with an adjusting device 3. The side walls of the horizontal seats of the two L-shaped support seats 1 are connected with a telescopic mechanism 4, and the heads of the cross bars of the two L-shaped support seats 1 are movably connected with a sliding mechanism 5. The sliding mechanism 5 and the side walls of the vertical seats of the L-shaped support seats 1 are connected by an inclined movable mechanism 6. The first ends of the supporting mechanism 2 and the movable mechanism 6 are driven by the adjusting device 3, the telescopic mechanism 4 is driven by the supporting mechanism 2, the sliding mechanism 5 is driven by the telescopic mechanism 4, and the second end of the movable mechanism 6 is driven by the sliding mechanism 5;

[0043] In this embodiment: in actual use, the width of the L-shaped support seat 1 is relatively wide. When the building template used is smaller than the width of the L-shaped support seat 1, the building template can be placed between the vertical seats of the L-shaped support seat 1 as needed. When the building template used is the same width as the L-shaped support seat 1, the vertical seat of the L-shaped support seat 1 can be directly used as a building template. When the building template used is larger than the width of the L-shaped support seat 1, multiple L-shaped support seats 1 need to be used. The connecting device 7 includes a rectangular block 71 and a connecting piece. The second side wall and the third side wall of the vertical seat of the two L-shaped support seats 1 are both installed with rectangular blocks 71. Through holes are opened on the rectangular blocks 71. The through holes on the two adjacent rectangular blocks 71 are detachably connected by a connecting piece. The connecting piece can be a bolt or a U-shaped connecting piece 72.

[0044] Example 1: When the building template used is smaller than the width of the L-shaped support base 1, the building template is placed on both sides of the wall reinforcement, and then the two L-shaped support bases 1 are also placed on both sides of the wall reinforcement, and the vertical seats of the two L-shaped support bases 1 are fit with the building template. The two L-shaped support bases 1 are connected through the connecting device 7 and the building template is pressed tightly. At this time, the connecting member selected is a bolt, and then the adjusting device 3 is adjusted according to the required height. The adjusting device 3 drives the first end of the supporting mechanism 2 and the movable mechanism 6 to move, the supporting mechanism 2 drives the telescopic mechanism 4 to move, the telescopic mechanism 4 drives the sliding mechanism 5 to move, and the sliding mechanism 5 drives the second end of the movable mechanism 6 to move until it moves to the appropriate height;

[0045] Example 2: When the building template and the L-shaped support base 1 used are the same width, the building template can be used as in Example 1, or two L-shaped support bases 1 can be directly placed on both sides of the wall reinforcement, and then the two L-shaped support bases 1 are connected by the connecting device 7. In this case, the connecting member selected is a bolt. At this time, the L-shaped support base 1 forms a building template. Finally, the adjustment device 3 is adjusted in the same way as in Example 1 until it moves to the appropriate height;

[0046] Example 3: When the building template used is larger than the width of the L-shaped support seat 1, first use a bolt connector to connect one end of the two L-shaped support seats 1 on both sides of the building template, then use a U-shaped connector 72 to connect the adjacent L-shaped support seats 1 on the same side of the building template, and finally use a bolt connector to connect the two L-shaped support seats 1 on both sides of the building template at the other end. At the same time, the building template squeezes the U-shaped connector 72 to make the connection between the adjacent L-shaped support seats 1 on the same side of the building template more secure, and then adjust the adjustment device 3 as needed until it moves to a suitable height; Figure 11 .

[0047] In this embodiment: screw holes are provided on the two rectangular blocks 71 on one L-shaped support seat 1, and through holes are provided on the two rectangular blocks 71 on the other L-shaped support seat 1. The purpose is to facilitate installation and disassembly, and to ensure that the two L-shaped support seats 1 can press the building formwork and the wall reinforcement when the bolts are tightened. Before use, the two L-shaped support seats 1 are separated. When in use, the two L-shaped support seats 1 are placed on both sides of the wall reinforcement, and then the bolts are passed through the through holes and the screw holes. At this time, the two L-shaped support seats 1 are fixed on both sides of the wall reinforcement, and the two L-shaped support seats 1 can press the wall reinforcement. Figure 2 .

[0048] The adjusting device 3 includes a first rotating shaft 31, a second rotating shaft 32, a first gear 33, a second gear 34, a turbine 35, a worm 36, a driving member 37, a second rack 38, and a first rack 39. The L-shaped support base 1 has a cavity structure. The first rotating shaft 31 is rotatably mounted on the side wall of the cavity at the vertical seat of the L-shaped support base 1.

The motor drives the worm 36 to adjust, which can achieve rapid adjustment. In addition, the self-locking of the turbine 35 and the worm 36 and the self-locking when the motor does not rotate are used. The double self-locking can ensure that the stability of the device is better after it is adjusted to the appropriate position. When the motor rotates forward, it drives the worm 36 to rotate clockwise, and the worm 36 drives the turbine 35 to rotate clockwise. The turbine 35 drives the second rotating shaft 32 to rotate clockwise, and the second The rotating shaft 32 drives the second gear 34 to rotate clockwise, the second gear 34 drives the first rotating shaft 31 to rotate counterclockwise, the first rotating shaft 31 drives the first gear 33 to rotate counterclockwise, and at the same time, the second gear 34 drives the second rack 38 to move downward, the first gear 33 drives the first rack 39 to move downward, at the same time, the first rack 39 drives the first end of the movable mechanism 6 to move downward, and the second rack 38 drives the support mechanism 2 to move downward. When the motor rotates in reverse, the movement process is opposite to the above process, and the first ends of the support mechanism 2 and the movable mechanism 6 both move upward;

[0051] Example 5: If it is used in a place where power supply is inconvenient, the driving member 37 is selected as a hand crank. When the hand crank rotates forward, the worm 36 is driven to rotate clockwise. The movement process is the same as that in Example 1. The second rack 38 drives the support mechanism 2 to move downward. When the hand crank rotates reversely, the support mechanism 2 and the first end of the movable mechanism 6 both move upward. Figure 3 .

[0052] The support mechanism 2 includes a support plate 21 and a first fixed block 22. The side wall of the second rack 38 is connected to the first fixed block 22. One side of the first fixed block 22 is connected to the telescopic mechanism 4. The other side of the first fixed block 22 is connected to the support plate 21.

[0056] Example 6: When the second rack 38 moves downward, the second rack 38 drives the first fixing block 22 to move downward, and the first fixing block 22 drives the second connecting rod 44 to move downward. The first protrusion 45 in the second end of the second connecting rod 44 slides downward along the oblique side of the trapezoidal block 41. At this time, the first end of the second connecting rod 44 moves downward and slides to the right along the T-slot 221. At the same time, the second connecting rod 44 also drives the horizontal rod of the L-shaped rod 43 to slide to the right along the first connecting rod 42 and the fourth side wall of the L-shaped support seat 1, and the vertical rod of the L-shaped rod 43 drives the sliding mechanism 5 to slide into the cavity;

[0057] Example 7: When the second rack 38 moves upward, the second rack 38 drives the first fixed block 22 to move upward, the second connecting rod 44 moves upward, and the first protrusion 45 in the second end of the second connecting rod 44 slides upward along the oblique side of the trapezoidal block 41.

Both side walls of the through groove 12 are provided with a second slide groove 13. Both side walls of the second fixed block 63 are provided with a second protrusion 631. The two second protrusions 631 slide in the two second slide grooves 13 respectively. The other side of the second fixed block 63 is hinged to the second end of the fourth connecting rod 62. The third connecting rod 61 A groove 64 is provided inside, and a third rack 65 is installed on the first end of the fourth connecting rod 62, and the third rack 65 is meshed with a third gear 66.

[0059] In this embodiment, the support angle formed by the third connecting rod 61 and the fourth connecting rod 62 can be fixed to an optimal angle during design, and the third connecting rod 61 and the fourth connecting rod 62 are combined to form a reinforcing rib. When the first end of the third connecting rod 61 and the second fixing block 63 move, they move synchronously, which can ensure that the support angle remains unchanged. Therefore, the angle between the fourth connecting rod 62 and the third connecting rod 61 and the vertical seat of the L-shaped support seat 1 is always the optimal angle; when the fourth connecting rod 62 slides in the groove 64, it will not touch the third gear 66, and the fourth connecting rod 62 will not interfere with the third gear 66 and the ratchet 610; the function of the torque spring is to ensure that when the third gear 66 rotates, the ratchet 610 can rotate, and after rotation, it will automatically engage with the pawl 69 under the action of the torque spring to prevent the fourth connecting rod 62 from sliding down;

[0060] Embodiment 8: When the first rack 39 moves upward, it drives the second fixing block 63 to slide upward, and the fourth connecting rod 62 slides outward along the groove 64. The fourth connecting rod 62 drives the third rack 65 to slide outward, and the third rack 65 drives the third gear 66 and the third rotating shaft 67 to rotate clockwise. The third rotating shaft 67 drives the ratchet 610 to rotate clockwise. When adjusted to a suitable position, the ratchet 610 and the pawl 69 are self-locking. When the building wall panel squeezes the L-shaped support seat 1, the ratchet 610 and the pawl 69 are locked tighter. At this time, the third connecting rod 61 and the fourth connecting rod 62 play the role of stable reinforcing ribs;

[0061] Embodiment 9: When the first rack 39 moves downward, it is necessary to pull the pulling piece first, so that the ratchet 610 and the pawl 69 are disengaged from the meshing limit position. Then, when the first rack 39 drives the second fixing block 63 to slide downward, the fourth connecting rod 62 slides inward along the groove 64, and the fourth connecting rod 62 drives the third rack 65 to slide inward. The third rack 65 drives the third gear 66 and the third rotating shaft 67 to rotate counterclockwise, and the third rotating shaft 67 drives the ratchet 610 to rotate counterclockwise. When it is adjusted to the appropriate position, the pulling piece is released. At this time, the ratchet 610 and the pawl 69 are self-locked, and the fourth connecting rod 62 will not slide downward. Figure 8 .

[0062] The pulling member includes a pull rope 611 and a U-shaped rod 612. The U-shaped rod 612 is slidably mounted on the third side wall of the groove 64 on one side of the third fixing block 68. The two vertical rods of the U-shaped rod 612 pass through the third side wall of the groove 64 and are located in the groove 64. The two vertical rod heads of the U-shaped rod 612 are connected to the first end of the pull rope 611, and the second end of the pull rope 611 is connected to the second end side wall of the pawl 69.

[0063] In this embodiment, the pull rope 611 is used to facilitate pulling the crossbar of the U-shaped rod 612 so that the pawl 69 disengages the ratchet 610. During the pulling process, the U-shaped rod 612 will not disengage from the groove 64 but will only slide up and down along the third side wall of the groove 64, which is convenient for operation. In actual use, if the U-shaped rod 612 is at a higher position, the U-shaped rod 612 can be pulled by an external wire or other tool.

[0064] Example 10: When the fourth connecting rod 62 needs to be slid outward along the groove 64, there is no need to pull the crossbar of the U-shaped rod 612, and the operation can be performed directly;

[0065] Example 11: When it is necessary to make the fourth connecting rod 62 slide inward along the groove 64, it is necessary to first pull the crossbar of the U-shaped rod 612 so that the two vertical rods of the U-shaped rod 612 slide downward along the third side wall of the groove 64. The two vertical rods of the U-shaped rod 612 move downward with the first end of the pull rope 611. The second end of the pull rope 611 can pull the pawl 69 out of the ratchet 610. At this time, the fourth connecting rod 62 can be adjusted to slide inward along the groove 64. After sliding to the appropriate position, the U-shaped rod 612 is released. At this time, under the action of the torque spring, the ratchet 610 and the pawl 69 automatically engage and self-lock; Figure 8 .

[0066] The working process of the present invention:

[0067] When in use, according to the width of the building template and the width of the L-shaped support base 1, first select one of the methods of embodiment 1, embodiment 2 and embodiment 3;

[0068] When power supply is convenient, the driving member is selected as a motor. At this time, when the height of the L-shaped support base 1 needs to be increased, the motor is started in reverse, and the motor drives the worm 36 to rotate counterclockwise. If it is used in a place where power supply is inconvenient, the driving member is selected as a hand crank. At this time, rotating the hand crank counterclockwise drives the worm 36 to rotate counterclockwise;

[0069] The worm 36 drives the turbine 35 to rotate counterclockwise, the turbine 35 drives the second rotating shaft 32 to rotate counterclockwise, the second rotating shaft 32 drives the second gear 34 to rotate counterclockwise, the second gear 34 drives the first rotating shaft 31 to rotate clockwise, the first rotating shaft 31 drives the first gear 33 to rotate clockwise, and at the same time, the second gear 34 drives the second rack 38 to move upward, the first gear 33 drives the first rack 39 to move upward, the second rack 38 drives the first fixed block 22 to move upward, the second connecting rod 44 moves upward, and the first protrusion 45 in the second end of the second connecting rod 44 slides upward along the oblique side of the trapezoidal block 41. At this time, the first end of the second connecting rod 44 moves downward and also slides to the left along the T-slot 221. The second connecting rod 44 also drives the crossbar of the L-shaped rod 43. The fourth side wall of the L-shaped support seat 1 slides to the left along the first connecting rod 42 and the vertical rod of the L-shaped rod 43 drives the sliding mechanism 5 to slide out of the cavity. At the same time, the second fixing block 63 slides upward. At the same time, the vertical rod of the L-shaped rod 43 pulls the sliding mechanism 5 to slide out of the cavity. At this time, the fourth connecting rod 62 slides outward along the groove 64. The fourth connecting rod 62 drives the third rack 65 to slide outward. The third rack 65 drives the third gear 66 and the third rotating shaft 67 to rotate clockwise. The third rotating shaft 67 drives the ratchet 610 to rotate clockwise. When adjusted to the appropriate position, the ratchet 610 and the pawl 69 are self-locking. When the building wall panel squeezes the L-shaped support seat 1, the ratchet 610 and the pawl 69 are stuck tighter. At this time, the third connecting rod 61 and the fourth connecting rod 62 play the role of stable reinforcing ribs.

[0070] When it is necessary to lower the height of the L-shaped support base 1 or retract the device, the horizontal rod of the U-shaped rod 612 is pulled first, so that the two vertical rods of the U-shaped rod 612 slide downward along the third side wall of the groove 64, and the two vertical rods of the U-shaped rod 612 move downward with the first end of the pull rope 611. The second end of the pull rope 611 can pull the pawl 69 out of the ratchet 610, and then the motor is started forward or the hand crank is turned forward, which drives the worm 36 to rotate clockwise, the worm 36 drives the turbine 35 to rotate clockwise, and the turbine 35 drives the second rotating shaft 32 clockwise. The second rotating shaft 32 drives the second gear 34 to rotate clockwise, the second gear 34 drives the first rotating shaft 31 to rotate counterclockwise, the first rotating shaft 31 drives the first gear 33 to rotate counterclockwise, and at the same time the second gear 34 drives the second rack 38 to move downward, the first gear 33 drives the first rack 39 to move downward, the second rack 38 drives the first fixed block 22 to move downward, the first fixed block 22 drives the second connecting rod 44 to move downward, and the first protrusion 45 in the second end of the second connecting rod 44 moves along the hypotenuse of the trapezoidal block 41 to the left. When the first rack 39 moves downward, it drives the second fixed block 63 to slide downward. At the same time, the vertical rod of the L-shaped rod 43 pulls the sliding mechanism 5 to slide into the cavity. The first rack 39 drives the second fixed block 63 to slide downward. When sliding down, the fourth connecting rod 62 slides inward along the groove 64, and the fourth connecting rod 62 drives the third rack 65 to slide inward. The third rack 65 drives the third gear 66 and the third rotating shaft 67 to rotate counterclockwise, and the third rotating shaft 67 drives the ratchet 610 to rotate counterclockwise. When adjusted to the appropriate position, release the U-shaped rod 612. At this time, under the action of the torque spring, the ratchet 610 and the pawl 69 automatically engage and self-lock. Finally, the connecting piece is removed from the through hole in reverse. At this time, the L-shaped support seat 1 and the wall reinforcement are out of the limit and can be disassembled for easy collection.

[0071] The present invention places two L-shaped support seats on both sides of the wall reinforcement, and then passes the connecting piece through the through hole. At this time, the L-shaped support seats are fixed on both sides of the wall reinforcement to press the wall reinforcement, and then the motor is started in reverse or the hand crank is rotated to drive the worm to rotate counterclockwise, the worm drives the turbine to rotate counterclockwise, the turbine drives the second rotating shaft to rotate counterclockwise, the second rotating shaft drives the second gear to rotate counterclockwise, the second gear drives the first rotating shaft to rotate clockwise, and the first rotating shaft drives the first gear to rotate clockwise, and the second connecting rod also drives the horizontal rod of the L-shaped rod to slide to the left along the first connecting rod and the fourth side wall of the L-shaped support seat, and the vertical rod of the L-shaped rod drives the sliding mechanism to slide out of the cavity. When it is adjusted to the appropriate position, the ratchet and pawl are used for self-locking. When the building wall panel squeezes the L-shaped support seat When the L-shaped support seat needs to be disassembled or lowered, it is only necessary to pull the U-shaped rod first, adjust the hand crank or motor to adjust the device in one step, and then loosen the U-shaped rod. At this time, under the action of the torque spring, the ratchet and pawl automatically engage and self-lock. The present invention is simple to operate and has strong practicality.
