Description

Technical Field

[0001] The present invention relates to the field of shear walls, and in particular to an assembled prefabricated reinforced concrete shear wall connection structure and method. Background Art

[0002] The shear wall in the existing prefabricated structure is a structural member that mainly bears the vertical and horizontal loads caused by wind loads or earthquakes, and has good lateral stiffness and seismic resistance.

[0003] At present, the shear wall connection form of prefabricated buildings is to leak out the reinforcement and then insert the steel bars for binding, and then pour concrete to ensure that the two shear walls form a whole. However, since the leaking reinforcement puts forward requirements for the side mold of the prefabricated wall, the mold needs to have long slots and holes, and then the steel bars are manually tied, which reduces the work efficiency. At the same time, it reduces the strength and service life of the mold, and also makes it difficult to remove the mold. There are also problems such as leakage.

[0004] In addition, prefabricated shear walls with missing reinforcement are difficult to operate and align when inserted and connected. For example, Chinese Patent Publication No. CN204728514U discloses a shear wall panel connection structure and a shear wall, which not only avoids the shear wall from missing reinforcement during the production process, but also reduces the difficulty of mold making, and improves production efficiency and on-site assembly efficiency. However, when inserting the steel bars into the ring buckles, this method also requires adjusting the spacing of the ring buckles so that the ring buckles can tightly fix the steel bars. However, due to the volume of the shear wall, it is inconvenient to adjust and increases the difficulty of pouring. Summary of the invention

[0005] One object of the present invention is to provide an assembled prefabricated reinforced concrete shear wall connection structure and method, which quickly aligns two shear walls through a first rotating rod and a second rotating rod, and connects steel bars between two first connecting plates, thereby further improving the connection stability and strength.

[0006] This purpose is achieved by adopting the following technical solutions:

[0007] An assembled prefabricated reinforced concrete shear wall connection structure and method, including a first connection plate connected to the shear wall, a plurality of rotating parts are arranged on the first connection plate, the rotating parts include a first rotating rod, a second rotating rod and an action member, the action member can act on the first rotating rod and the second rotating rod to rotate the first rotating rod and the second rotating rod by 90 degrees on the first connection plate; in the original state, the first rotating rod and the second rotating rod rotate 0 degrees on the first connection plate, and the first rotating rod and the second rotating rod are parallel to the first connection plate. The rotating rods are all connected with connecting rings, and the connecting rings are used to pass the steel bars;

[0008] When two shear walls need to be connected, one of the shear walls is placed above the other shear wall, the action piece rotates the first rotating rod and the second rotating rod by 90 degrees, the connecting rope passes through the connecting rings on the first rotating rod and the second rotating rod in turn, and the connecting rope is pulled to make the center of the connecting rings of the first rotating rod and the second rotating rod corresponding to each other on the two first connecting plates collinear. After taking out the connecting rope, the steel bar is passed through the connecting ring to complete the preliminary connection of the two shear walls. After the preliminary connection is completed, the shear wall located above is moved downward. When the shear wall moves downward, it acts on the first rotating rod and the second rotating rod to rotate the first rotating rod and the second rotating rod to a position parallel to the first connecting plate, shortening the distance between the two first connecting plates, and completing the further connection of the two shear walls. After the connection, the two shear walls are further fixed by the screws on the two first connecting plates. Finally, concrete is poured on the first connecting plate between the two shear walls to complete the connection.

[0009] The existing upper and lower joints of prefabricated reinforced concrete shear walls are mostly connected by steel sleeve grouting. This connection method has problems such as difficulty in steel bar alignment, poor grouting material fullness and inconvenience in detection, which has caused serious quality risks and hindered the development of prefabricated assembled concrete structures. In addition, the existing joints have exposed steel bars, which not only makes transportation difficult, but also affects the quality of the shear wall itself.

[0010] This structure does not require adjustment of the structure of the shear wall itself, but only requires connecting the first connecting plate to the shear wall. When the two shear walls are connected, precise alignment is not required. The first rotating rod and the second rotating rod are directly rotated to allow the two shear walls to be aligned at a longer distance. There is no need to move the shear walls too much. The initial alignment can be achieved by directly passing the connecting rope through the connecting ring and straightening the connecting rope. Under the guidance of the connecting rope, the steel bars can be passed through the connecting ring to initially fix the two shear walls. When the shear walls are further moved subsequently, no further alignment operation is required. The connection can be directly aligned by rotating the first rotating rod and the second rotating rod, and steel bars are arranged between the two first connecting plates to further improve the stability of the connection.

[0011] Among them, the action member can be of various structures. The inventor has preferred a gear interaction structure. Specifically, the action member includes a telescopic rod, and the opposite ends of the first rotating rod and the second rotating rod are connected to a rotating shaft. The telescopic rod is meshed with the two rotating shafts, and the telescopic rod is extended and retracted up and down to make the first rotating rod and the second rotating rod rotate in opposite directions. The telescopic movement of the telescopic rod up and down simultaneously adjusts the rotation of the first rotating rod and the second rotating rod, which can further adjust the stability of the two shear walls when they are close to each other, so that they are stably connected in close movement, and when they are close to each other, the two shear walls can ensure alignment without excessive operation and adjustment.

[0012] Furthermore, a plurality of through slots are provided on the steel bar, and the plurality of through slots correspond to the plurality of telescopic rods one by one. When the two shear walls are initially connected, the first rotating rod and the second rotating rod are rotated 90 degrees, and the telescopic rod is located inside the first connecting plate. When the first rotating rod and the second rotating rod are further rotated so that the first rotating rod and the second rotating rod are parallel to the first connecting plate, the telescopic rod is located outside the first connecting plate and inserted into the corresponding through slots. The position of the steel bar between the two shear walls is further fixed, the connection stability is improved, and the steel bar is prevented from slipping out.

[0013] Preferably, the lower end of the telescopic rod is located outside the first connecting plate and connected to the movable plate. Therefore, when adjusting the position of the telescopic rod, the position of the telescopic rod can be adjusted by adjusting the position of the movable plate, and all telescopic rods can be adjusted simultaneously through the movable plate, which is easy to operate and more conducive to the connection and use of the shear wall.

[0014] Secondly, a spring is arranged between the first rotating rod and the first connecting plate, and a spring is arranged between the second rotating rod and the first connecting plate. When the two shear walls are connected close to each other, the spring is used for buffering, thereby improving the stability of the connection and avoiding collision when the two shear walls are connected quickly.

[0015] Preferably, the length of the first rotating rod and the second rotating rod is greater than 5 cm. The width of the first rotating rod and the second rotating rod is the same as the outer diameter of the steel bar.

[0016] Furthermore, the connection structure includes two mutually parallel first connection plates, one of which is connected to the shear wall, and a connection block is connected between the two mutually parallel first connection plates. The structure in which the connection block is connected between the two mutually parallel first connection plates constitutes an I-shaped steel structure, a transverse plate is arranged on the connection block, and a plurality of longitudinal plates are arranged on the transverse plate.

[0017] The transverse plate improves the bending stiffness and shear stiffness of the joint, and the longitudinal plate not only improves the bending stiffness and shear stiffness of the joint, but also serves as the connection surface of the negative moment reinforcement of the floor slab. The first connecting plate is provided with bolt holes to facilitate further fixed connection with the adjacent shear wall.

[0018] On the other hand, a connection method of an assembled prefabricated reinforced concrete shear wall connection structure comprises the following steps:

[0019] One of the shear walls is positioned above the other shear wall, the action member is adjusted to rotate the first rotating rod and the second rotating rod by 90 degrees, and the connecting rope is passed through the connecting rings of the first rotating rod and the second rotating rod corresponding to each other on the two first connecting plates;

[0020] Straighten the connecting rope so that the centers of the connecting rings of the first rotating rod and the second rotating rod are in the same line;

[0021] Pull the connecting rope out of the connecting ring and pass the steel bar through the corresponding connecting ring;

[0022] The adjusting member makes the first rotating rod and the second rotating rod parallel to the first connecting plate, and aligns the two first connecting plates;

[0023] The first connecting plates of the two shear walls are connected by bolts, and cement is poured between the two first connecting plates.

[0024] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0025] The present invention discloses an assembled prefabricated reinforced concrete shear wall connection structure and method. The present invention realizes preliminary connection of two shear walls at a certain distance through a first rotating rod and a second rotating rod on a first connecting plate, which makes it easier for workers to align and connect the two shear walls safely and quickly. At the same time, after the two shear walls are initially connected, the distance between the two shear walls is shortened under the action of the first rotating rod and the second rotating rod, and the first rotating rod and the second rotating rod can also be used for buffering, thereby further improving the safety of the connection and the ease of operation.

[0026] Secondly, during the initial connection, passing the steel bars through the connecting ring can further increase the stress-bearing performance of the two shear walls at the connection, and the first rotating rod and the second rotating rod can also increase the stress effect and improve the performance of the connection between the two shear walls.

[0027] Moreover, when the structure is connected, there is no complicated operation, and two shear walls can be connected quickly and safely. It is more suitable for the connection of shear walls, and there is no need to change the structure of the shear wall, and there is no need to expose steel bars on the shear wall, which further improves the performance.

The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0046] Example 1

[0047] The connection structure includes an upper joint and a lower joint connected to the upper and lower ends of the shear wall. The upper joint and the lower joint have the same structure. Both the upper joint and the lower joint include a first connection plate 1. When two shear walls need to be connected, the first connection plate on the lower joint of one of the shear walls is welded to the ground or other structures, and the first connection plate on the upper joint of the shear wall is connected to the first connection plate of the lower joint of the other shear wall correspondingly.

[0048] The first connecting plate 1 is provided with a plurality of rotating parts, the rotating parts including a first rotating rod 6, a second rotating rod 7 and an action part, the action part can act on the first rotating rod 6 and the second rotating rod 7, so that the first rotating rod 6 and the second rotating rod 7 are rotated 90 degrees on the first connecting plate 1; the rotating rods 6 are connected with connecting rings 12, such as Fig. 9 As shown, the connecting ring 12 is used to pass through the steel bar 10.

[0049] In some embodiments, the plurality of groups of rotating members on the first connecting plate 1 may be arranged in one row or in multiple rows.

[0050] When several groups of rotating parts on the first connecting plate 1 are arranged in a row, the two first connecting plates between the two shear walls correspond to one steel bar, and the rotating parts between the two shear walls correspond to each other. During the connection process, another shear wall is suspended above the shear wall, and the first connecting plate on the lower connecting head of the upper shear wall is opposite to the first connecting plate on the upper connecting head of the lower shear wall. The rotating parts on the two opposite first connecting plates 1 are adjusted to rotate the first rotating rod 6 and the second rotating rod 7 by 90 degrees, and one end of the connecting rope is passed through the first rotating rod 6 and the second rotating rod 7 on the two opposite first connecting plates from left to right or from right to left in turn, and the connecting rope is straightened, as shown in FIG. Figure 1 As shown, two first rotating rods 6 on the corresponding rotating members correspond to each other, two second rotating rods 7 on the corresponding rotating members correspond to each other, and the centers of the connecting rings on all the first rotating rods 6 and the second rotating rods 7 are collinear.

[0051] Insert the steel bar 10 into the connecting rings on the first rotating rod 6 and the second rotating rod 7. Figure 2As shown, the connecting rope is pulled out from the connecting ring to complete the preliminary connection of the two first connecting plates, i.e., the two shear walls.

[0052] The upper shear wall is moved downward. During the downward movement of the shear wall, the first rotating rod 6 and the second rotating rod 7 rotate. Figure 3 As shown, during the rotation process, since the connecting ring is connected to the first rotating rod 6 and the second rotating rod 7 by hinges, the connecting ring is always located on the steel bar. When the first rotating rod 6 and the second rotating rod 7 rotate to their original states, as shown in FIG. Figure 4 As shown, the first rotating rod 6 and the second rotating rod 7 are parallel to the first connecting plate 1, and the steel bar is located between the two first connecting plates, thereby completing the further connection of the two first connecting plates, namely, the two shear walls.

[0053] After the connection, cement is poured between the two first connection plates of the two shear walls to complete the fixed connection of the two shear walls.

[0054] In some embodiments, when several groups of rotating parts on the first connecting plate 1 are arranged in multiple rows, several steel bars are arranged between the two shear walls, and the several steel bars are located on the same horizontal plane. The number of steel bars corresponds to the number of rows of rotating parts. When 5 rows of rotating parts are arranged on the first connecting plate, 5 steel bars are arranged between the two first connecting plates between the two shear walls, and the 5 steel bars pass through the connecting rings on each row of rotating parts respectively.

[0055] Example 2

[0056] On the basis of the above embodiment, the action member acts on the first rotating rod 6 and the second rotating rod 7 to rotate the first rotating rod 6 and the second rotating rod 7 90 degrees on the first connecting plate 1, wherein the action member can be a variety of structures, for example, the first rotating rod 6 and the second rotating rod 7 are rotated by a telescopic component, or the first rotating rod 6 and the second rotating rod 7 are rotated by a rotating component, the rotating component can be a motor, and the action member can also be other structures as long as it can achieve rotation.

[0057] In this embodiment, the inventors have preferably selected an action member, specifically, Figure 5 As shown, the action member includes a telescopic rod 9, and the opposite ends of the first rotating rod 6 and the second rotating rod 7 are connected to a rotating shaft 8. The telescopic rod 9 and the two rotating shafts 8 are provided with matching gears. The telescopic rod 9 is located between the two rotating shafts 8, and the telescopic rod 9 is meshed with the two rotating shafts 8. In the original state, the first rotating rod 6, the second rotating rod 7 and the first connecting plate 1 are parallel to each other. Figure 5 When the telescopic rod 9 moves downward, as shown in FIG. Figure 6 As shown, the telescopic rod 9 acts on the first rotating rod 6 and the second rotating rod 7 to make the first rotating rod 6 and the second rotating rod 7 rotate 90 degrees in the opposite direction.

[0058] In some embodiments, a plurality of through grooves are provided on the steel bar 10. When the steel bar is inserted into the corresponding connecting ring, the through grooves on the steel bar 10 correspond to the plurality of telescopic rods 9 one by one. When the first rotating rod 6 and the second rotating rod 7 rotate 90 degrees, Figure 7 As shown, the telescopic rod 9 is located in the first connecting plate 1; when the first rotating rod 6 and the second rotating rod 7 are parallel to the first connecting plate 1, as shown in FIG. Figure 8 As shown, the telescopic rod 9 is located outside the first connecting plate 1 and inserted into the corresponding through groove.

[0059] In some embodiments, the lower end of the telescopic rod 9 is located outside the first connecting plate 1 and connected to the movable plate 2. Therefore, when adjusting the position of the telescopic rod 9, all the telescopic rods can be adjusted simultaneously by directly adjusting the position of the movable plate, and then the angles of all the first rotating rods 6 and the second rotating rods 7 can be adjusted simultaneously through the movable plate, which is more convenient for operation.

[0060] Preferably, when the first rotating rod 6 and the second rotating rod 7 are parallel to the first connecting plate 1 , the movable plate 2 and the first connecting plate 1 are in contact with each other.

[0061] In some embodiments, a spring is provided between the first rotating rod 6 and the first connecting plate 1 , and a spring is provided between the second rotating rod 7 and the first connecting plate 1 .

[0062] In some embodiments, the lengths of the first rotating rod 6 and the second rotating rod 7 are greater than 5 centimeters.

[0063] In some embodiments, the width of the first rotating rod 6 and the second rotating rod 7 is the same as the outer diameter of the steel bar 10 .

[0064] Example 3

[0065] Based on the above embodiments, Fig.10 As shown, the upper joint and the lower joint each include two mutually parallel first connection plates 1, one of which is connected to the shear wall, and a connection block is connected between the two mutually parallel first connection plates 1. A transverse plate 3 is arranged on the connection block, and a plurality of longitudinal plates 4 are arranged on the transverse plate 3.

[0066] A structure in which a connecting block is connected between two mutually parallel first connecting plates 1 constitutes an I-shaped steel structure. The transverse plate 3 improves the bending stiffness and shear stiffness of the joint. The longitudinal plate 4 not only improves the bending stiffness and shear stiffness of the joint, but also serves as a connecting surface for the negative moment reinforcement of the floor slab. Bolt holes are provided on the first connecting plate 1 to facilitate further fixed connection with the adjacent shear wall.

[0067] In some embodiments, a plurality of bolt holes 5 are provided on the first connection plates 1 in the upper joint and the lower joint that are not connected to the shear wall. When two shear walls are connected, the two first connection plates are further connected through the bolt holes.

[0068] like Fig.11 As shown, the upper and lower ends of the shear wall are respectively connected to the upper joint and the lower joint, the first connecting plate located below the upper joint is welded to the upper end of the shear wall, and the first connecting plate located above the lower joint is welded to the lower end of the shear wall.

[0069] In some embodiments, a groove 11 is provided on the first connecting plate 1, and the first rotating rod 6 and the second rotating rod 7 in the rotating member are both located in the groove 11. When the first rotating rod 6 and the second rotating rod 7 rotate to a position parallel to the first connecting plate 1, the first rotating rod 6 and the second rotating rod 7 are located in the groove 11.

[0070] In some embodiments, two rows of rotating members are disposed on the first connecting plate, and each row is disposed with two rotating members.

[0071] In some embodiments, the first connecting plate in the upper joint connected to the shear wall is a connecting plate, and there are no rotating parts and bolt holes on the connecting plate. The first connecting plate in the upper joint that is not directly connected to the shear wall is provided with a rotating part and a bolt hole, which is used to connect with the rotating part and the bolt hole on the first connecting plate in the lower joint that is not directly connected to the shear wall.

[0072] The first connecting plate in the lower joint connected to the shear wall is a connecting plate, and there are no rotating parts and bolt holes on the connecting plate. The first connecting plate in the lower joint that is not directly connected to the shear wall is provided with a rotating part and a bolt hole, which is used to connect with the rotating part and the bolt hole on the first connecting plate in the upper joint that is not directly connected to the shear wall.

[0073] A connection method for an assembled prefabricated reinforced concrete shear wall connection structure comprises the following steps:

[0074] When two shear walls need to be connected, such as Fig.12 As shown, the lower joint of the shear wall located above is connected to the upper joint of the shear wall located below, that is, the first connecting plate located below the lower joint is connected to the first connecting plate located above the upper joint.

[0075] During the connection process, one of the shear walls is located above the other shear wall, the first connecting plate with the lower joint located below is opposite to the first connecting plate with the upper joint located above, the telescopic rod 9 is adjusted to rotate the first rotating rod 6 and the second rotating rod 7 on the two opposite first connecting plates 90 degrees, one end of the connecting rope is passed through the connecting ring from left to right in sequence, the connecting rope is pulled so that the center of the connecting ring on the first rotating rod 6 and the second rotating rod 7 is on the same straight line, the steel bars are passed through the connecting rings of the first rotating rod 6 and the second rotating rod 7 on the same row, and then the connecting rope is taken out from the connecting ring to complete the preliminary connection of the first rotating rod 6 and the second rotating rod 7.

[0076] The shear wall located above is moved downward. During the movement, the telescopic rod moves to rotate the first rotating rod 6 and the second rotating rod 7 to a direction horizontal to the first connecting plate. During the rotation, the distance between the two shear walls is shortened. Fig.13 As shown, the telescopic rod is inserted into the through groove on the steel bar. Preferably, the telescopic rods in the corresponding rotating parts in the two first connecting plates correspond to each other. Therefore, when the telescopic rod is inserted into the steel bar, the two corresponding telescopic rods are inserted into the through groove of the steel bar at the same time, and the two corresponding telescopic rods are located on the same straight line and perpendicular to the steel bar, thereby improving the strength of the connection and further improving the stability of the connection. In the process of connecting the two shear walls, the first rotating rod 6 and the second rotating rod 7 are driven to rotate, which can buffer the two shear walls and improve stability.

[0077] After the first rotating rod 6 and the second rotating rod 7 are rotated to a direction horizontal to the first connecting plate, bolts are inserted into the bolt holes 5 to connect the two opposite first connecting rods, further fix the two first connecting plates, and then fix the two shear walls.

[0078] The cement is poured between the two shear walls, that is, between the two first connection plates that are in contact with the shear walls, to achieve final fixation of the two shear walls.

[0079] In some embodiments, the first rotating rod 6 and the second rotating rod 7 are made of steel, and the telescopic rod is made of steel, which further improves stability.
