Description

Technical Field

[0001] The present invention relates to the field of building construction, and more specifically to a formwork reinforcement device at the corner of a super-thick shear wall. Background Art

[0002] A shear wall is also known as a wind-resistant wall, seismic wall or structural wall. It is a wall in a building or structure that mainly bears the horizontal load and vertical load (gravity) caused by wind load or seismic action, preventing the structure from shear (shearing) failure. Also known as a seismic wall, it is generally made of reinforced concrete.

[0003] Shear walls are divided into plane shear walls and tube shear walls. Plane shear walls are used in reinforced concrete frame structures, lift slab structures, and flat slab floor systems. To increase the stiffness, strength and anti-collapse ability of the structure, cast-in-place or precast reinforced concrete shear walls can be used in certain parts. The cast-in-place shear wall is cast simultaneously with the surrounding beams and columns, with good integrity. Tube shear walls are used in high-rise buildings, high-rise structures and suspended structures, surrounded by the partition walls of elevator shafts, stairwells, equipment and auxiliary rooms. The tube walls are all cast-in-place reinforced concrete walls, and their stiffness and strength can withstand larger horizontal loads compared to plane shear walls. When casting a shear wall, formwork support and reinforcement are required. The formwork reinforcement generally uses steel or wooden beams to assemble into a formwork bracket, and uses steel or wooden poles to build a scaffolding to form a bracket support, and cooperates with steel formwork for concrete construction. Since the shear wall is the main load-bearing wall in a building or structure, its thickness and extension method are different from ordinary walls. In the process of reinforcing the corner of a super-thick shear wall with traditional formwork reinforcement methods, the following problems often occur:

[0004] Due to the spatial variation at the corner of the shear wall, it is difficult for traditional formwork reinforcement methods to adapt to the thickness and angle changes at the corner of the shear wall, and it is difficult to fill and support the corner gap of the formwork at the corner of the shear wall, reducing the compressive and anti-deformation ability of the formwork at the corner of the shear wall.

[0005] Traditional formwork reinforcement methods are difficult to assemble or disassemble quickly in the limited space at the corner of the shear wall, reducing the assembly and disassembly rate of the supporting formwork, and it is difficult to provide anti-collision protection for the reinforced part at the corner of the shear wall, reducing the stability of the reinforced formwork and the safety of construction workers during operation, and also reducing the reuse rate of the reinforced formwork.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0040] An embodiment of the present invention is described with reference to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 13 , a formwork reinforcement device at the corner of a super-thick shear wall, including a plate surface 1, a cross beam 2, a vertical beam 3, a nut 4, a plastic pipe 5 and a bolt 6. The plate surface 1 is attached to the wall surface of the shear wall 00. A plurality of groups of bolts 6 are symmetrically installed up and down between two opposite plate surfaces 1. The bolts 6 all penetrate the plate surface 1. A plastic pipe 5 is sleeved on the bolts 6, and the plastic pipe 5 is located between two opposite plate surfaces 1. The end of the bolt 6 is installed with a nut 4 by means of threaded cooperation. A vertical beam 3 is jointly installed between the plate surface 1 and the bolt 6. The vertical beams 3 are arranged at equal intervals on the inner and outer sides of the corner of the shear wall 00, and a cross beam 2 is jointly installed between the multiple vertical beams 3. A plurality of groups of configuration grooves 11 are symmetrically opened at the upper and lower ends of the plate surface 1. A buckle 12 is fixedly installed in each configuration groove 11. The buckle 12 is of a double-layer "I" shape structure. Card slots 31 are opened at the upper and lower ends of the vertical beam 3, and the card slots 31 are in clamping cooperation with the buckles 12.

[0041] As an implementation mode of the present invention, such as Figure 8 , Figure 9 , Figure 10 , Figure 12 and Figure 13As shown in the figure, the vertical beam 3 has a three-section structure. The upper and lower sections of the vertical beam 3 are short rods 32 with the same structure, and both the upper and lower short rods 32 of the vertical beam 3 are clamped in the buckle 12 through the card slots 31. The cross beam 2 is located at the position of the long rod 33 in the middle section of the vertical beam 3, and the cross beam 2 is fixedly connected to the vertical beam 3. The end of the plastic pipe 5 penetrates through the plate surface 1, and the end of the plastic pipe 5 is located at the connection part between the long rod 33 and the short rod 32 of the vertical beam 3. A chuck 7 is slidably sleeved on the outer wall of the plastic pipe 5. The chuck 7 is an incomplete circular ring structure. The screw rod penetrates through the axis position of the chuck 7. Symmetrically arranged on both sides of the chuck 7 are circular rings with a fan-shaped longitudinal section, and the circular rings are respectively located on both sides of the vertical beam 3. Trapezoidal protrusions are symmetrically arranged up and down in the middle of the chuck 7. Trapezoidal grooves are arranged at the end positions of the long rod 33 and the short rod 32 of the vertical beam 3 to cooperate with the trapezoidal protrusions.

[0042] During specific operation, in the initial working condition, the staff installs the buckle 12 into the configuration groove 11. Subsequently, the staff assembles the plate surface 1 and the shear wall 00 to be poured. Then, the bolt 6 passes through two opposite plate surfaces 1 horizontally. During the process of the bolt 6 passing through horizontally, the plastic pipe 5 is sleeved on the bolt 6. Then, the chuck 7 is sleeved on the end of the bolt 6, and the assembly operation among the vertical beam 3, the buckle 12 and the chuck 7 is carried out. During this process, the card slot 31 at the end of the short rod 32 is clamped into the buckle 12. Subsequently, after the installation of the vertical beam 3 is completed, the staff carries out the assembly operation between the cross beam 2 and the vertical beam 3.

[0043] As an implementation mode of the present invention, as Figure 10 、 Figure 12 and Figure 13 shown, a claw 61 is slidably sleeved on the end of the bolt 6. The claw 61 is in a "C" shape, and the claw 61 is located between the chuck 7 and the vertical beam 3. Docking grooves 30 are arranged at the ends of the long rod 33 and the short rod 32 of the vertical beam 3. The two ends of the claw 61 are respectively clamped and matched with the docking grooves 30 on the long rod 33 and the short rod 32. One end of the nut 4 is fixedly installed with a pressing ring 41, and the pressing ring 41 abuts against the side wall of the claw 61. A roller 71 is installed on the circular ring part of the chuck 7 through a rotational fit, and the roller 71 is attached to the side wall of the vertical beam 3 through a rolling fit. A strengthening seat 72 is fixedly installed in the middle of the chuck 7. Strengthening ribs 73 are commonly installed on the strengthening seats 72 between adjacent two chucks 7. The strengthening ribs 73 located inside the corner of the shear wall 00 are arranged obliquely, and the strengthening ribs 73 at this position are perpendicular to the diagonal line of the corner of the shear wall 00. A fastening ring 8 is commonly installed between the two strengthening ribs 73 located outside the corner of the shear wall 00. One side of the fastening ring 8 is provided with a notch, and the side walls of the notch of the fastening ring 8 are respectively attached to the side walls of the plate surface 1 at the corner of the shear wall 00. Anti-collision foam strips 84 are uniformly arranged along the circumferential direction on the outer ring surface of the other side of the fastening ring 8.

[0044] During the actual operation, during the combined installation of the vertical beam 3 and the chuck 7, the worker sleeved the jaw 61 onto the bolt 6 and made the end of the jaw 61 snap into the docking groove 30. Subsequently, the nut 4 was installed at the end of the bolt 6 and tightened. During the tightening of the nut 4, the pressing ring 41 gradually abutted against the side wall of the jaw 61, and through the abutting action, the jaw 61 was closely attached to the side walls of the chuck 7, the long rod 33, and the short rod 32. With the support of the rear part of the plate surface 1, the short rod 32 and the long rod 33 can be kept vertically placed on both the upper and lower sides of the chuck 7, thereby preventing the vertical beam 3 from deflecting and moving in the front-back direction. Through the auxiliary support of the roller 71 on the side wall of the vertical beam 3, the vertical beam 3 can be prevented from deflecting and moving in the left-right direction. And during the tightening of the nut 4, the two opposite plate surfaces 1 are closely attached to the steel structure support of the shear wall 00 to be cast. When the installation of the vertical beam 3 is completed, the worker connects and fixes the reinforcing seat 72 and the reinforcing rib 73, so that the positions of two adjacent vertical beams 3 are relatively fixed. Subsequently, the worker installs the fastening ring 8 on the reinforcing rib 73 outside the shear wall 00, and fastens the splicing part between the two plate surfaces 1 outside the shear wall 00 through the fastening ring 8. The foam strip 84 arranged on the outer surface of the fastening ring 8 can provide anti-collision protection for the protruding part of the fastening ring 8, improving the stability after the installation of the fastening ring 8 and the safety of the construction workers during operation.

[0045] As an embodiment of the present invention, as Figure 4 , Figure 5 , Figure 7 , Figure 9 and Figure 11 shown, a extension rod 74 is fixedly installed in the middle of the reinforcing rib 73. The extension rod 74 is located inside the corner position of the shear wall 00, and the extension rod 74 is parallel to the diagonal line at the corner of the shear wall 00. An extrusion plate 741 is installed at the end of the extension rod 74. The extrusion plate 741 is trapezoidal, and the trapezoidal side edges of the extrusion plate 741 are respectively attached to the side walls of the plate surface 1 at the corner of the shear wall 00. The extrusion plates 741 are arranged at equal intervals from top to bottom at the inner corner of the shear wall 00. An inner support rod 742 is commonly installed between the multiple extrusion plates 741 arranged at equal intervals. A water bag 743 is detachably installed at the end of the extrusion plate 741. The water bag 743 is located at the corner edge position of the shear wall 00, and the side wall of the water bag 743 is attached to the plate surface 1 at the corner of the shear wall 00.

[0046] During specific operation, multiple extrusion plates 741 are successively and equidistantly installed on the inner support rod 742 by the staff. Subsequently, the extension rod 74 is installed on the reinforcing rib 73, and the two extrusion plates 741 at the upper and lower ends of the inner support rod 742 are fixed by the extension rod 74. Through the fitting and abutting action between the extrusion plate 741 and the plate surface 1, the corners of the plate surface 1 at the corners can be prevented from skewing. The water bag 743 arranged at the end of the extrusion plate 741 can adapt to and fit into the corner gap at the corner of the plate surface 1. With the external clamping support of the fastening ring 8, the stability of the support for the plate surface 1 at the corner of the shear wall 00 can be further improved.

[0047] As an implementation manner of the present invention, as Figure 6 , Figure 8 , Figure 9 , Figure 14 and Figure 15 shown, the fastening rings 8 are arranged at equal intervals from top to bottom at the outer corner of the shear wall 00. The fastening rings 8 and the extrusion plates 741 are at the same height. An outer pull rod 81 is commonly installed between the multiple fastening rings 8 arranged at equal intervals. The outer pull rod 81 is parallel to the inner support rod 742. Fastening plates 82 are symmetrically arranged along the tangent direction of the outside of the fastening ring 8. The fastening plates 82 are parallel to the plate surface 1, and the fastening plates 82 are connected to the reinforcing rib 73. A pull plate 83 is arranged along the radial direction of the middle of the fastening ring 8. The pull plate 83 is parallel to the fastening plate 82 and the pull plate 83 fits on the side wall of the plate surface 1. An annular surface is arranged in the middle of the pull plate 83. A plurality of push rods 831 are installed on the annular surface along its circumferential direction in a hinge manner. The plurality of push rods 831 are arranged in an "X" shape, and the plurality of push rods 831 are all in contact with the side wall of the plate surface 1. An elastic pad 832 is arranged at the end of the push rod 831, and the elastic pad 832 is in contact with the side wall of the plate surface 1. An embedding groove 821 is opened in the middle of the fastening plate 82. A "C" - shaped guiding ring 822 is fixedly installed at the port part of the embedding groove 821. The end of the reinforcing rib 73 slides through the guiding ring 822 and the end of the reinforcing rib 73 is located inside the embedding groove 821. A plurality of upright claws 833 are detachably installed in the middle of the pull plate 83. The plurality of upright claws 833 are arranged at equal intervals. The upright claws 833 are located between the pull plate 83 and the fastening plate 82, and an "L" - shaped fold with an obtuse - angled inclination is arranged at the end of the upright claw 833. A plurality of square grooves 731 are equidistantly opened at the end of the reinforcing rib 73. A locking block 732 is installed in each square groove 731 in a rotational fit manner. A torsion spring is connected between the locking block 732 and the reinforcing rib 73. The locking block 732 is engaged with the upright claw 833, and an inclined surface for sliding fit with the upright claw 833 is arranged on one side of the locking block 732.

[0048] During specific operation, during the installation process of the fastening ring 8, the end of the reinforcing rib 73 enters the embedding groove 821 from the position of the guiding ring 822. The locking block 732 arranged in the square groove 731 synchronously enters the embedding groove 821. After the locking block 732 reaches the predetermined penetration depth, the locking block 732 is blocked by the vertical claw 833 and deflects. Subsequently, when the locking block 732 passes over the position of the vertical claw 833, under the torsional force of the torsion spring, the locking block 732 resets and is clamped with the "L"-shaped corner end of the vertical claw 833, further locking the relative position between the reinforcing rib 73 and the fastening ring 8. After the installation of the fastening ring 8 is completed, the push rods 831 are all attached to the side wall of the plate surface 1. Through the "X"-shaped expansion, the effective supporting area for supporting the plate surface 1 can be increased. The provided elastic pad 832 can avoid leaving indentations during the support of the plate surface 1 through elastic contact, thereby improving the reuse rate of the plate surface 1. After the fastening rings 8 on the upper and lower sides of the plate surface 1 are both installed, the staff assembles the outer pull rod 81, and the fastening rings 8 are sequentially installed at equal intervals on the outer pull rod 81, so that the fastening rings 8 are arranged on the outside of the plate surface 1 at the corner for auxiliary support operation.

[0049] During operation:

[0050] First step: In the initial working condition, the staff installs the buckle 12 into the configuration groove 11. Subsequently, the staff assembles the plate surface 1 and the shear wall 00 to be cast. Then, the bolt 6 passes through two opposite plate surfaces 1. During the process of the bolt 6 passing through, the plastic pipe 5 is sleeved on the bolt 6. Then, the chuck 7 is sleeved on the end of the bolt 6, and the assembly operation among the vertical beam 3, the buckle 12, and the chuck 7 is carried out. During this process, the slot 31 at the end of the short rod 32 is clamped into the buckle 12. Subsequently, after the installation of the vertical beam 3 is completed, the staff carries out the assembly operation between the cross beam 2 and the vertical beam 3.

[0051] Step 2: During the combined installation of the vertical beam 3 and the chuck 7, the worker sleeved the jaw 61 onto the bolt 6 and made the end of the jaw 61 snap into the docking groove 30. Subsequently, the nut 4 was installed at the end of the bolt 6 and tightened. During the tightening of the nut 4, the pressing ring 41 gradually abutted against the side wall of the jaw 61, and through the abutting action, the jaw 61 was closely attached to the side walls of the chuck 7, the long rod 33, and the short rod 32. With the support of the rear part of the plate surface 1, the short rod 32 and the long rod 33 could be kept vertically placed on both the upper and lower sides of the chuck 7, thus preventing the vertical beam 3 from deflecting and moving in the front-back direction. Through the auxiliary support of the roller 71 on the side wall of the vertical beam 3, the vertical beam 3 could be prevented from deflecting and moving in the left-right direction. During the tightening of the nut 4, the two opposite plate surfaces 1 were closely attached to the steel structure support of the shear wall 00 to be poured. After the installation of the vertical beam 3 was completed, the worker connected and fixed the reinforcing seat 72 and the reinforcing rib 73, thereby relatively fixing the positions of two adjacent vertical beams 3.

[0052] Step 3: The worker sequentially installed a plurality of pressing plates 741 at equal intervals onto the inner support rod 742. Subsequently, the extension rod 74 was installed onto the reinforcing rib 73, and the two pressing plates 741 at the upper and lower ends of the inner support rod 742 were fixed through the extension rod 74. Through the fitting and abutting action between the pressing plate 741 and the plate surface 1, the corners of the plate surface 1 at the corner could be prevented from deflecting. The water bag 743 provided at the end of the pressing plate 741 could adapt to and fit into the corner gap at the corner of the plate surface 1. With the external clamping support of the fastening ring 8, the stability of the support for the plate surface 1 at the corner of the shear wall 00 could be further improved.

[0053] Step 4: Install the fastening ring 8 onto the reinforcing rib 73 on the outer side of the shear wall 00 by the staff. During this process, the end of the reinforcing rib 73 enters the embedding groove 821 from the position of the guiding ring 822, and the locking block 732 arranged in the square groove 731 synchronously enters the embedding groove 821. After the locking block 732 reaches the predetermined entering depth, the locking block 732 is blocked by the vertical claw 833 and deflects. Subsequently, after the locking block 732 passes over the position of the vertical claw 833, under the torsion of the torsion spring, the locking block 732 resets and is clamped with the "L"-shaped corner end of the vertical claw 833, further locking the relative position between the reinforcing rib 73 and the fastening ring 8. After the installation of the fastening ring 8 is completed, the push rods 831 are all attached to the side wall of the plate surface 1. Through the "X"-shaped extension, the effective supporting area for supporting the plate surface 1 can be increased. The elastic pad 832 provided can avoid leaving indentations during the support of the plate surface 1 through elastic contact, thereby improving the reuse rate of the plate surface 1. After the fastening rings 8 on the upper and lower sides of the plate surface 1 are all installed, assemble the outer pull rod 81 by the staff, and sequentially install the fastening rings 8 at equal intervals on the outer pull rod 81, so that the fastening rings 8 are arranged on the outer side of the plate surface 1 at the corner, and perform auxiliary support operations.
