Abstract
Description
Technical Field
[0001] The invention relates to the technical field of construction engineering, in particular to a prefabricated reinforced concrete shear wall. Background Art
[0002] Shear wall, also known as wind-resistant wall, earthquake-resistant wall or structural wall, is a wall in a house or structure that mainly bears horizontal loads and vertical loads (gravity) caused by wind loads or earthquakes to prevent structural shear (shear) damage. Prefabricated shear wall is a main building structure that is predetermined and assembled on site. It is mass-produced in the factory and then transported to the construction site for assembly. The shear wall is prefabricated or semi-prefabricated, and then spliced with the wall panels on site, with a small amount of pouring to realize the construction of the entire building, which speeds up the construction of the building and meets the trend of modern commercialization. In order to produce the steel sleeves of the prefabricated shear wall and accurately insert them into the steel bars of the wall panel, it is usually necessary to position the steel sleeves reserved for the shear wall during the production process of the prefabricated shear wall.
[0003] At present, shear wall components generally need to be hoisted to the installation position after being transported to the construction site, and partially cast and connected with other components or reserved steel bars of the floor slab. During the hoisting process, in order to make the sleeve in the component accurately align with the reserved steel bars, several workers are usually required to hold the shear wall when it is about to reach the installation position, and adjust the shear wall in a suspended state from multiple angles to accurately position it. Then the crane puts the shear wall in place. In this process, the shear wall is prone to shaking due to the large number of people holding it and the uncoordinated force or the wrong angle, making it difficult to quickly position and connect the shear wall with the base steel bars, which in turn affects the assembly efficiency of the shear wall. In addition, the suspended components are heavy, and long-term installation poses a relatively large risk to operators. Summary of the invention

Thus, a sealed space can be formed by the slide bar 801, the slide shell 7, the fixed plate 802 and the movable plate 803. When the movable plate 803 moves upward, the air in the sealed space can be squeezed and pushed. At this time, ventilation grooves 806 are symmetrically opened through the inner wall of the grouting cavity 3, and a through hole 805 is opened through the side wall of the two slide shells 7 away from each other corresponding to the ventilation groove 806, and the inner wall of the through hole 805 is connected with the inner wall of the ventilation groove 806, so that the sealed space is ventilated.

[0022] Embodiment 2: Based on the above embodiment, the inner wall of the movable groove 6 is provided with an in-position disengagement component 9 .
[0023] Further, the in-place disengagement component 9 includes a sleeve 901, and the outer wall of the sleeve 901 is fixedly connected to the inner wall of the installation groove 816, the top of the sleeve 901 passes through the inner wall of the movable groove 6, and a cavity 902 is opened at the top of the sleeve 901, and the inner wall of the cavity 902 is slidably connected with a support block 903, and the outer walls of the top two sides of the sleeve 901 are penetrated by a through groove 1 904, and the inner wall of the through groove 1 904 is slidably connected with a clamping block 905, and the side wall of the two clamping blocks 905 away from each other is inclined, and the side wall of the two clamping blocks 905 away from each other is in contact with the inner wall edge of the movable groove 6, the top of the support block 903 is inclined, and the bottom of the support block 903 is fixedly connected with a spring 906, and the other end of the spring 906 is fixedly connected to the inner wall of the cavity 902; In this embodiment, after the steel bar body 13 is installed in place, the next step of pouring can be carried out. The slurry is transported to the inside of the grouting cavity 3 through the pouring hole 14 opened on the surface of the shear wall 1 and connected to the grouting cavity 3. When the slurry is fully transported, the slurry will flow out from another pouring hole 14. Then, the outer wall of the casing 901 is fixedly connected to the inner wall of the mounting groove 816, and the top of the casing 901 passes through the inner wall of the movable groove 6, and a cavity 902 is opened at the top of the casing 901, and the inner wall of the cavity 902 is slidably connected with a support block 903, and the outer walls on both sides of the top of the casing 901 are penetrated with a through groove 1 904, and the inner wall of the through groove 1 904 is slidably connected with a block 905, and the side wall of the two blocks 905 away from each other is inclined, and the two blocks 905 away from each other are inclined. One side wall is in contact with the inner wall edge of the movable groove 6, so that under normal conditions, when the movable plate 4 rises, it will synchronously drive the two connecting blocks 5 to rise, so that the inclined surfaces of the two card blocks 905 will be squeezed through the movable groove 6, so that the two card blocks 905 are close to each other, but at this time, the side wall of the two card blocks 905 that are close to each other is in contact with the two side walls of the support block 903, so that they cannot move, so that when the connecting block 5 rises, the two card blocks 905 can drive the movable plate 803 to rise synchronously; When the slurry is fully filled in the grouting cavity 3, the slurry will squeeze and fill the surrounding parts in the grouting cavity 3. At this time, a spring four 906 is fixedly connected to the bottom of the support block 903, and the other end of the spring four 906 is fixedly connected to the inner wall of the cavity 902. Therefore, under normal circumstances, the spring four 906 supports the current position of the support block 903. When the slurry squeezes the surrounding parts, the support block 903 can be pressed into the shell 901, so that the side wall of the two blocks 905 that are close to each other contacts with the inclined surface of the top of the support block 903, that is, the blocks 905 can approach each other at this time. At this time, the movable plate 803 is at the highest point, so that the return elastic force of the spring one 804 can be used to drive the shell 901 to detach from the movable groove 6. At this time, the top of the blocking column 812 is truncated cone-shaped, and one side of the shell 901 is A through slot 907 is formed through the wall, and the inner wall of the through slot 907 is slidably connected with a top plate 908. At the same time, one end of the top plate 908 facing the support block 903 is inclined. When the support block 903 contracts, the top plate 908 is pressed by the inclined surface, so that the top plate 908 presses the blocking column 812. The outer wall inclined surface of the blocking column 812 is used to make the top plate 908 fit into the position between the blocking column 812 and the movable plate 803, that is, the through hole 811 is kept in an open state, and the sealed space is no longer maintained. At this time, the two positioning clamps 810 can be driven back to their original positions by the reset elastic force of the spring 808, and the surface of the steel bar body 13 is no longer clamped and positioned, thereby avoiding the contact surface of the positioning clamp 810 generating a stress concentration point on the steel bar after casting, which increases the risk of steel bar breakage when encountering wind loads. As described above, when the shear wall 1 is assembled, when the alignment is completed and grouting is ready, the support block 903 can be contracted by filling and squeezing the slurry, thereby releasing the connection between the movable disk 4 and the movable plate 803, and opening the second through hole 811, so that the two positioning clamps 810 can automatically release the clamping and positioning of the steel bars, avoiding the contact surface of the positioning clamps 810 to generate stress concentration points on the steel bars after casting, increasing the risk of steel bar breakage when encountering wind loads, thereby helping to improve the overall structural safety of the shear wall 1.
[0024] Embodiment 3: Based on the above embodiment, two side walls of the sliding shell 7 are provided with vibration defoaming components 10 .
[0025] Furthermore, the vibration defoaming component 10 includes a connecting plate 1001, and a trigger block 1002 is fixedly connected to one side wall of two connecting plates 1001 at an equal distance, and a through groove 3 1003 is penetrated and opened on the outer wall of both sides of the sliding shell 7 corresponding to the trigger block 1002, and the outer wall of the trigger block 1002 is fitted and slid with the inner wall of the through groove 3 1003, and the end portions of the two trigger blocks 1002 at the same level that are close to each other are inclined; In this embodiment, after the sleeve shell 901 is driven to disengage from the movable groove 6 by the restoring elastic force of the spring 1 804, the spring 1 804 will drive the movable plate 803 to return to its original position, and the trigger block 1002 is fixedly connected to the side wall of the two connecting plates 1001 at an equal distance, and the outer walls of the two sides of the sliding shell 7 are penetrated by the trigger block 1002, and the outer wall of the trigger block 1002 is fitted and slid with the inner wall of the through groove 1003, and the end portions of the two trigger blocks 1002 at the same level are close to each other and are inclined, so that the movable plate 803 When moving downward, the multiple trigger blocks 1002 will be squeezed, and the two connecting plates 1001 will be moved away from each other by the inclined surface. At this time, a spring 5 1004 is fixedly connected to the side wall where the two connecting plates 1001 are close to each other, and the other end of the spring 5 1004 is fixedly connected to the outer walls of both sides of the sliding shell 7, so that the elastic force of the spring 5 1004 can drive the connecting plates 1001 to approach each other again, so that the connecting plates 1001 can vibrate continuously after the pouring is completed, so as to vibrate and remove bubbles from the inside of the pouring slurry, which helps to reduce the amount of bubbles inside the slurry.
[0026] As described above, when the shear wall 1 is assembled, when the movable disk 4 and the movable plate 803 are disconnected, the plurality of trigger blocks 1002 can be contacted and squeezed by the movable plate 803 that moves downward, so that the connecting plate 1001, in cooperation with the spring 1004, can be continuously vibrated after the pouring is completed, so as to vibrate and remove bubbles from the inside of the pouring slurry, which helps to reduce the amount of bubbles in the slurry, and further helps to improve the structural density and durability of the shear wall 1.
[0027] Working principle: When assembling the shear wall 1, first use a crane to lift the shear wall 1 and suspend it above the wall panel 12, so that the sleeve body 2 and the steel bar body 13 are initially aligned, and then lower the shear wall 1 so that the steel bar body 13 can be inserted into the sleeve body 2. At this time, the connecting block 5 will be connected to the movable plate 803 through the in-place disengagement component 9, so that the movable plate 4 can be lifted up by the relative movement of the steel bar body 13, and then the movable plate 803 can be driven to move upward by the movable plate 4.
[0028] Then, when the movable plate 803 moves upward, the air in the sealed space can be squeezed and pushed, so that the pushed air squeezes the support column 809, so that the two positioning clamps 810 can move synchronously and fit and squeeze the surface of the steel bar, ensuring that the steel bar body 13 is located at the internal center position of the sleeve body 2 for positioning and installation.
[0029] Then, under normal circumstances, the blocking column 812 blocks the through hole 2 811 through the elastic force of spring three 815 to maintain a sealed space. When the positioning and clamping force of the two positioning clamps 810 on the steel bar body 13 reaches a certain level, that is, when the pressure in the sealed space reaches a certain height, as the movable plate 803 moves and compresses, the elastic force will be greater than the pulling force of spring three 815, so that the blocking column 812 is pushed open by the air, so that the pressure in the sealed space is appropriately reduced, and then it can automatically deflate, so that the positioning clamp 810 can maintain an appropriate clamping force, ensuring that the positioning clamp 810 clamps the steel bar with a constant force.
[0030] Then, when the grouting cavity 3 is fully filled with the slurry, the slurry will squeeze and fill the surrounding parts in the grouting cavity 3, thereby pressing the support block 903 into the casing 901, so that the side wall of the two clamping blocks 905 close to each other contacts the inclined surface at the top of the support block 903, that is, the clamping blocks 905 can be close to each other at this time, and the movable plate 803 is at the highest point, so that the reset elastic force of the spring 1 804 can be used to drive the casing 901 to detach from the movable groove 6. When the support block 903 contracts, it will contact the top plate 901 through the inclined surface. 8 is extruded so that the top plate 908 squeezes the blocking column 812, and the outer wall slope of the blocking column 812 is used to make the top plate 908 be stuck in the position between the blocking column 812 and the movable plate 803, that is, the through hole 811 is kept in an open state, and the sealed space is no longer maintained. At this time, the two positioning clamps 810 can be driven back to their original positions by the reset elastic force of the spring 808, and the surface of the steel bar body 13 is no longer clamped and positioned, thereby avoiding the contact surface of the positioning clamp 810 to generate stress concentration points on the steel bar after casting.
[0031] Then, after the sleeve shell 901 is driven to disengage from the movable groove 6 by the restoring elastic force of spring 1 804, the spring 1 804 will drive the movable plate 803 back to its original position. When the movable plate 803 moves downward, the multiple trigger blocks 1002 will be squeezed, and the two connecting plates 1001 will be moved away from each other by the inclined surface, so that the connecting plates 1001 can be driven to move closer to each other by the elastic force of spring 5 1004, so that the connecting plates 1001 can vibrate continuously after the pouring is completed, so as to vibrate and remove bubbles from the inside of the pouring slurry, which helps to reduce the amount of bubbles inside the slurry.
