Description

Technical Field

[0001] This application relates to the field of wall construction, and in particular to a shear wall formwork assembly device and its construction method. Background Technology

[0002] A shear wall, also known as a wind-resistant wall, earthquake-resistant wall, or structural wall, is a wall in a building or structure that primarily bears horizontal and vertical loads (gravity) caused by wind or earthquakes, preventing structural shear failure. It is typically made of reinforced concrete.

[0003] Shear walls need to be poured in advance. During pouring, formwork is needed to shape the shear walls. After the formwork is erected, the expansion of the concrete may push the formwork to move and create gaps, resulting in more burrs on the shear walls. At the same time, since tie bolts need to be installed, the tie bolts need to pass through the wall. After the wall has solidified and shaped, the wall needs to be repaired, which affects work efficiency. Summary of the Invention

[0004] To improve the stability of the connection between templates and avoid the formation of holes in the solidified wall, this application provides a shear wall formwork closing device and its usage method.

[0005] The shear wall formwork closing device provided in this application adopts the following technical solution: A shear wall formwork closing device includes a template for closing the formwork. One side of the template has a connecting rod for connecting to an adjacent template, and a locking block is fixedly connected to the connecting rod. The other side of the template has a connecting groove for inserting and engaging with the connecting rod on the adjacent template. The inner wall of the connecting groove has a locking slot for engaging with the locking block. A pushing block for moving the template is slidably disposed on the locking block. The pushing block can abut against the inner wall of the locking slot on the adjacent template. Each template has a first driving component for driving the connecting rod to move, and the connecting rod has a second driving component for driving the pushing block to move.

[0006] By adopting the above technical solution, when the operator assembles the template, the operator inserts the connecting rod on the template into the connecting groove on the adjacent template. The first drive component drives the connecting rod to move, and the connecting rod slides in the connecting groove so that the locking block contacts the inner wall of the groove. Then, the second drive component drives the pushing block to move, and the pushing block moves and contacts the inner wall of the groove. The pushing block pushes the adjacent template to move, so that the gap between the two templates gradually decreases and fits together, reducing the possibility of burrs and preventing the gap between the two templates from increasing due to the expansion of concrete during solidification.

[0007] Preferably, the first driving assembly includes a first control screw, which passes through the end of the template near the adjacent connecting groove. The first control screw is rotatably connected to the template. A sliding seat is sleeved on the first control screw, and the sliding seat is threadedly engaged with the first control screw. A connecting rod is disposed on the sliding seat. A return spring is fixedly connected to the sliding seat. The end of the return spring away from the sliding seat is fixedly connected to the control screw. A first sliding groove is formed on the outer wall of the template for sliding engagement with the sliding seat. A third driving assembly for driving the first control screw to rotate is provided on the template.

[0008] By adopting the above technical solution, after the connecting rod is inserted into the connecting groove on the adjacent template, the third drive component drives the first control screw to rotate. The rotation of the first control screw causes the sliding seat to move, the movement of the sliding seat causes the connecting rod to move, and the movement of the connecting rod causes the locking block to move and abut against the inner side wall of the locking groove, thereby connecting the two templates together.

[0009] Preferably, the third drive assembly includes a worm gear and a worm. The worm gear is fixedly sleeved on the first control screw, and the worm passes through the template. The worm is rotatably connected to the template, and the worm meshes with the worm gear.

[0010] By adopting the above technical solution, the operator rotates the worm gear, which in turn causes the worm wheel to rotate. The rotation of the worm wheel causes the first control screw to rotate, and the rotation of the first control screw causes the sliding seat to move. The template needs to be vibrated multiple times during pouring. Due to the self-locking property of the worm wheel and worm gear, the possibility of the first control screw rotating due to vibration is reduced.

[0011] Preferably, the second drive assembly includes a second control screw, which passes through the locking block and is rotatably connected to the locking block. The second control screw also passes through the pushing block, which is threadedly engaged with the second control screw. A first spur gear is fixedly sleeved on the end of the second control screw away from the pushing block. A fourth drive assembly for driving the first spur gear to rotate is provided inside the template, and a fifth drive assembly for driving the pushing block back to its initial position is provided inside the template.

[0012] By adopting the above technical solution, after the connecting block is inserted into the connecting groove and the locking block abuts against the groove, the fourth drive component drives the first spur gear to rotate. The rotation of the first spur gear causes the second control screw to rotate. The rotation of the second control screw causes the push block to move and pull the template to fit the two templates together. When the template needs to be removed after the pouring is completed, the fifth drive component drives the first spur gear to rotate in the opposite direction. The rotation of the first spur gear in the opposite direction causes the push block to move back to the initial position.

[0013] Preferably, the fourth drive assembly includes a first crown gear and a drive shaft. The drive shaft passes sequentially through the sliding seat and the connecting rod. A second spur gear is fixedly sleeved at one end of the drive shaft, and a third spur gear is fixedly sleeved at the other end. A sleeve passes through the connecting rod, and a second crown gear is fixedly sleeved on the sleeve. The second crown gear meshes with the second spur gear. The first crown gear is disposed on the sleeve and slidably disposed within the locking block. The first crown gear can mesh with the first spur gear. A rotating shaft passes through the template, and a third crown gear is fixedly sleeved on the rotating shaft. The third crown gear can mesh with the third spur gear. Pulleys are fixedly sleeved on both the rotating shaft and the first control screw, and a transmission belt is wound around the pulleys. A first control assembly for controlling the movement of the first crown gear is provided on the locking block.

[0014] By adopting the above technical solution, after the connecting rod is inserted into the connecting groove on the adjacent template, the operator rotates the worm gear. The rotation of the worm gear causes the worm wheel to rotate, which in turn causes the first control screw to rotate. The rotation of the first control screw causes the sliding seat to move, which in turn causes the connecting rod to move. The locking block follows the connecting rod and is inserted into the locking groove. At this time, the first control component drives the first crown gear to move and meshes with the first spur gear. The sliding seat moves to the unthreaded position of the first control screw. The first control screw continues to rotate but cannot cause the sliding seat to move further. At this time, the third spur gear stops moving and meshes with the third crown gear. The first control screw continues to rotate, causing the pulley to rotate. The pulley rotates, causing the rotating shaft to rotate. The rotating shaft rotates, causing the third crown gear to rotate. The third crown gear rotates, causing the third spur gear to rotate. The third spur gear rotates, causing the drive shaft to rotate. The drive shaft rotates, causing the second spur gear to rotate. The second spur gear rotates, causing the second crown gear to rotate. The second crown gear rotates, causing the sleeve to rotate. The sleeve rotates, causing the first crown gear to rotate. The first crown gear rotates, causing the first spur gear to rotate. The first spur gear rotates, causing the second control screw to rotate. The second control screw rotates, causing the push block to move.

[0015] Preferably, the first control component includes a trigger block and a support rod. The trigger block is slidably disposed on the locking block and can abut against the inner sidewall of the locking slot. The support rod is slidably disposed inside the locking block. One end of the support rod is rotatably connected to the trigger block, and the other end of the support rod is inserted into the sleeve. The first crown gear is fixedly sleeved on the support rod. A limit block is fixedly connected to the support rod. A limit groove is provided on the inner sidewall of the sleeve for sliding cooperation with the limit block.

[0016] By adopting the above technical solution, after the connecting rod is inserted into the connecting groove, the first control screw rotates to move the sliding seat, the sliding seat moves to move the connecting rod, the connecting rod moves to move the locking block, the locking block moves to move the trigger block, the trigger block moves and abuts against the inner side wall of the slot, the locking block continues to move to move the trigger block into the locking block, the trigger block moves to move the support rod, the support rod moves to move the first crown gear, the first crown gear moves and meshes with the first spur gear.

[0017] Preferably, the fifth drive assembly includes a first inner ratchet and a second inner ratchet. The first inner ratchet is fixedly sleeved on the end of the sleeve near the second control screw. A fourth crown gear is fixedly sleeved on the first inner ratchet. A transmission gear is rotatably installed inside the locking block. The fourth crown gear meshes with the transmission gear, and the transmission gear meshes with the first spur gear. The second inner ratchet is fixedly sleeved on the end of the drive shaft near the third spur gear. A fourth spur gear is fixedly sleeved on the second inner ratchet. A rack is provided inside the template, and the fourth spur gear meshes with the rack.

[0018] By adopting the above technical solution, under the action of the first inner ratchet and the second inner ratchet, the connecting rod moves to make the block fit against the inner wall of the slot. When the rack causes the fourth spur gear to rotate, it cannot cause the second inner ratchet to rotate. At the same time, when the sleeve rotates in the forward direction, it will not cause the fourth crown gear to rotate. When the template is removed, the operator rotates the worm gear in the reverse direction. The worm gear reverses, causing the worm wheel to reverse. The worm wheel reverses, causing the first control screw to rotate in the reverse direction. Under the action of the return spring, the sliding seat can be in constant contact with the thread on the first control screw. The first control screw rotates in the reverse direction, causing the sliding seat to move to the initial position. During the movement of the sliding seat, the rack causes the fourth spur gear to rotate. The rotation of the fourth spur gear causes the second inner ratchet to rotate. The rotation of the second inner ratchet causes the drive shaft to rotate in the reverse direction. The reverse rotation of the drive shaft causes the second spur gear to rotate in the reverse direction. The reverse rotation of the second spur gear causes the second crown gear to rotate in the reverse direction, and the sleeve rotates in the reverse direction. The reverse rotation of the sleeve causes the first inner ratchet to rotate. The rotation of the first inner ratchet causes the fourth crown gear to rotate. The rotation of the fourth crown gear causes the transmission gear and the first spur gear to rotate. The rotation of the first spur gear causes the second control screw to rotate, and the push block moves to the initial position.

[0019] Preferably, the connecting rod is hinged to the sliding seat, and the drive shaft includes a first drive rod and a second drive rod. The first drive rod and the second drive rod are connected by a universal joint. The first drive rod is rotatably installed inside the connecting rod. A second spur gear is fixedly sleeved on the end of the first drive rod away from the second drive rod. The second drive rod is rotatably installed inside the sliding seat. A third spur gear is fixedly sleeved on the end of the second drive rod away from the first drive rod. An auxiliary groove is provided on the template located at the edge of the wall. The auxiliary groove can engage with the rotated connecting rod.

[0020] By adopting the above technical solution, when working at the edge of the wall, operators can also improve the stability of the connection between the formwork at the inside and outside corners of the shear wall by using connecting rods and auxiliary grooves.

[0021] Preferably, the template is provided with an auxiliary support plate, and a third control screw is passed through the template. The third control screw is rotatably connected to the template. Both ends of the auxiliary support plate are hinged to the template. The third control screw passes through the auxiliary support plate and is threadedly engaged with the auxiliary support plate. The auxiliary support plate abuts against the template.

[0022] By adopting the above technical solution, the operator rotates the third control screw, which causes the auxiliary support plate to move and fit tightly against the outer wall of the template. This replaces the tie bolts, helps the template bear the lateral pressure of the concrete and other loads, and ensures that the spacing between the inner and outer templates meets the design requirements.

[0023] This application also provides a construction method for a shear wall, employing the following technical solution: S1. Determine the template position lines and template control lines, and apply foam tape; S2. Install the shear wall external corner template and the shear wall internal corner template in sequence. When setting the template located at the edge of the wall, rotate the connecting rod to connect the connecting rod with the auxiliary groove. S3.

S4. Rotate the third control screw to keep the auxiliary support plate and template in close contact and set the triangular support frame; S5. Pour cement mortar at the bottom to prevent the wall from rotting at the base; S6. Concrete is poured in layers, and the concrete is vibrated twice during pouring to make it dense.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a push block, after the two templates are connected together by the connecting block and the connecting groove, the distance between the two templates is continuously reduced to make them fit tightly, thereby reducing the possibility of burrs forming in the shear wall; 2. By setting the first control component, the depth of the card block entering the card slot can be guaranteed, and the contact area between the pushing block and the card slot can be guaranteed; 3. By setting up an auxiliary support plate, the operator rotates the third control screw. The rotation of the third control screw causes the auxiliary support plate to move and fit tightly against the outer wall of the template. This replaces the tie bolts, helps the template bear the lateral pressure of the concrete and other loads, ensures that the spacing between the inner and outer templates meets the design requirements, and avoids leaving holes in the wall.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a shear wall formwork closing device. (Refer to...) Figure 1 A shear wall formwork assembly includes a template 1.

[0031] Reference Figure 1 as well as Figure 2An auxiliary support plate 51 is provided on the outer wall of template 1. The auxiliary support plate 51 consists of two retractable arc plates and a horizontal plate. One end of the horizontal plate is hinged to one of the arc plates, and the other end of the horizontal plate is hinged to the other arc plate. The end of the arc plate away from the horizontal plate is hinged to the outer wall of template 1. A third control screw 52 is horizontally inserted through template 1. The third control screw 52 is rotatably connected to template 1, passes through the auxiliary support plate 51, and is threadedly engaged with the auxiliary support plate 51.

[0032] Reference Figure 1 The operator rotates the third control screw 52, ​​which causes the auxiliary support plate 51 to move and fit tightly against the outer wall of the template 1. This replaces the tie bolts and helps the template 1 withstand the lateral pressure of the concrete and other loads, ensuring that the spacing between the inner and outer templates 1 meets the design requirements.

[0033] Reference Figure 2 as well as Figure 3 The template 1 is vertically arranged, and several connecting rods 11 are inserted into the side wall of the template 1 near the adjacent template 1. The connecting rods 11 are spaced apart along the height direction of the template 1. The side wall of the adjacent template 1 near the connecting rods 11 has a connecting groove 111 along its width direction. The connecting rods 11 are inserted into the connecting grooves 111 on the adjacent template 1, and the connecting rods 11 and the connecting grooves 111 correspond one-to-one. The connecting rods 11 are horizontally arranged, and a locking block 13 is fixedly connected to the top surface of the connecting rod 11. A locking groove 112 is opened in the top surface of the connecting groove 111, and the locking block 13 is engaged with the locking groove 112.

[0034] Reference Figure 2 as well as Figure 3 A first driving assembly, including a first control screw 2, is provided on the template 1. Several first control screws 2 are vertically inserted into the template 1, rotatably connected to the template 1, and fixedly connected to the adjacent ends of adjacent first control screws 2. A sliding seat 21 is fitted onto each first control screw 2, threadedly engaged with it. The sliding seat 21 extends out of the template 1 and is hinged to a connecting rod 11, with each sliding seat 21 corresponding to a connecting rod 11. Several first grooves are formed along the height direction on the side wall of the template 1 near adjacent templates, and the sliding seats 21 slide against the inner side wall of the first grooves. Two return springs 22 are fitted onto each first control screw 2, symmetrically arranged along the axis of the sliding seat 21. One end of each return spring 22 is fixedly connected to the first control screw 2, and the other end is fixedly connected to the sliding seat 21. When the first control screw 2 rotates, the sliding seat 21 moves, and the movement of the sliding seat 21 causes the connecting rod 11 to move in the vertical direction, and the locking block 13 on the connecting rod 11 is inserted into the locking groove 112.

[0035] Reference Figure 2 as well as Figure 3 A third drive assembly is provided on template 1, which includes a worm gear 23 and a worm 24. The worm gear 23 is fixedly sleeved on the first control screw 2 located at the top of template 1, and the worm 24 is horizontally inserted inside template 1, rotatably connected to template 1, and meshing with the worm gear 23. When the operator rotates the worm 24, the rotation of the worm gear 24 causes the worm gear 23 to rotate, which in turn causes the first control screw 2 to rotate. The rotation of the first control screw 2 causes the sliding seat 21 to move, which in turn causes the connecting rod 11 to move. The movement of the connecting rod 11 causes the locking block 13 to move and abut against the inner wall of the slot 112, thereby connecting the two templates 1 together. Since template 1 needs to be vibrated multiple times during pouring, the self-locking property of the worm gear 23 and the worm 24 reduces the possibility of the first control screw 2 rotating due to vibration.
