Description

Technical Field

[0001] This utility model belongs to the field of concrete shear wall technology, and specifically relates to a high-efficiency connection structure device for prefabricated integral concrete shear walls. Background Technology

[0002] The prefabricated monolithic concrete shear wall high-efficiency connection structure is a key technology in prefabricated buildings. It uses prefabricated wall panels for all or part of the shear wall, connecting them with composite floor slabs and other components through reliable methods such as post-cast concrete and cement-based grouting to form a unified structure. Its characteristics include high prefabrication rate, fast construction, good quality, and excellent seismic performance. It is mainly used in high-rise residential buildings, and its overall load-bearing performance is comparable to that of cast-in-place shear wall structures, designed as "equivalent to cast-in-place."

[0003] However, existing concrete shear wall connection devices still have some shortcomings. When pouring shear walls, since the width of the overall shear wall structure is fixed, if the width of the poured device deviates from the expected width, the user cannot make relative adjustments. Consequently, the user has to replace the entire device for adjustment, which reduces the efficiency of the shear wall construction. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a high-efficiency connection structure device for assembled monolithic concrete shear walls to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A high-efficiency connection structure device for assembled monolithic concrete shear walls includes a first limiting frame, a movable frame sleeved on one side of the first limiting frame, a second limiting frame fixedly connected to one side of the movable frame, a first concrete shell sleeved on the inner side of the first limiting frame, a movable plate sleeved on one side of the first concrete shell, a second concrete shell fixedly connected to one side of the movable plate, a base plate snapped into the bottom end of the first concrete shell, a connecting frame installed at the top end of the base plate, a limiting block fixedly connected to the top end of the first limiting frame, a first slot formed on the other side of the limiting block extending into the interior of the first concrete shell, a second slot formed on the inner wall of the first slot, a circular groove formed on the inner side of the first slot, a first locking block snapped into the inner side of the first slot, and a second locking block fixedly connected to the outer side of the first locking block, the second locking block snapping into the inner side of the circular groove.

[0007] As a preferred technical solution, a retaining spring that matches the second retaining block is installed on the inner side of the circular groove. One side of the second retaining block is engaged with the other side of the retaining spring. The second retaining block is engaged with the inner side of the circular groove by the retaining spring. A sealing block is fixedly connected to the other side of the first retaining block. The sealing block covers the other side of the first retaining groove. A protrusion is fixedly connected to the other side of the sealing block. The protrusion has an arc-shaped corner.

[0008] As a preferred technical solution, a rubber pad is fixedly connected to the other side of the limiting block. The rubber pad is five millimeters thick. The first slot is located on the inner side close to the rubber pad. The other side of the rubber pad is in contact with one side of the sealing block.

[0009] As a preferred technical solution, a positioning block is fixedly connected to the top of the base plate, and a positioning groove matching the positioning block is opened at the bottom of the first concrete shell, and the positioning block is engaged with the inside of the positioning groove.

[0010] As a preferred technical solution, a sealing ring is fixedly connected to the top of the base plate, the positioning block is located on the inner side close to the sealing ring, and a sealing groove matching the sealing ring is opened at the bottom of the first concrete sleeve, with the sealing ring covering the inner side of the sealing groove.

[0013] In summary, the present invention has the following main advantages:

[0014] Firstly, during use, the second locking block can be inserted into the circular groove by using the first locking block. The second locking block can be adjusted to a different angle from the second locking groove so that it can be locked into the circular groove, so that the first limiting frame and the first concrete sleeve form a whole. This also makes it easier for the user to pour concrete by reinforcing it with the connecting frame. If the width of the overall device deviates slightly from the expected width, the user can pull the first limiting frame through the connecting movable frame. The first limiting frame can move the first concrete sleeve together, thereby extending the overall device. This effectively solves the inconvenience caused by the inability to adjust the width of the overall device, and also effectively improves the efficiency of subsequent concrete pouring.

[0015] Secondly, when the concrete pouring is completed and a shear wall is formed, the user can first adjust the second locking block to the corresponding angle with the second locking slot, and then directly pull out the first locking block to separate the first limiting frame and the second limiting frame. Then, through the locking principle of the positioning block, the first concrete shell and the second concrete shell are pulled upward to pull out the positioning block. At the same time, it is also convenient for the user to separate the first concrete shell and the second concrete shell through the locking principle of the movable plate, so that the outer shell structure of the entire device can be disassembled to facilitate subsequent inspection and maintenance of the concrete shear wall.

A first locking block 23 is engaged, and a second locking block 24 matching the second locking slot 19 is fixedly connected to the outside of the first locking block 23. The second locking block 24 is engaged inside the circular groove 21. In use, the second locking block 24 is inserted into the circular groove 21, and then the second locking block 24 is adjusted to a non-corresponding angle with the second locking slot 19, so that the second locking block 24 can be engaged into the circular groove 21, so that the first limiting frame 1 and the first concrete shell 10 form a whole. It also facilitates the user to pour concrete by reinforcing it with the connecting frame 7. If the width of the overall device deviates slightly from the expected width, the user can pull the first limiting frame 1 through the sleeved movable frame 2. The first limiting frame 1 can drive the first concrete shell 10 to move together, thereby achieving the effect of extending the overall device and effectively solving the inconvenience caused by the inability to adjust the width of the overall device.

[0024] refer to Figures 1 to 4 A retaining spring 22 matching the second retaining block 24 is installed on the inner side of the circular groove 21. One side of the second retaining block 24 is engaged with the other side of the retaining spring 22. The second retaining block 24 is engaged with the inner side of the circular groove 21 through the retaining spring 22. A sealing block 25 is fixedly connected to the other side of the first retaining block 23. The sealing block 25 covers the other side of the first retaining groove 18. A protrusion 26 is fixedly connected to the other side of the sealing block 25. The protrusion 26 has an arc-shaped corner. Due to the presence of the retaining spring 22, the engagement of the retaining spring 22 can further limit the position of the second retaining block 24, thereby further improving the stability of the engagement of the second retaining block 24. At the same time, it also effectively improves the stability of the engagement of the first concrete sleeve 10.

[0025] refer to Figures 1 to 4A rubber pad 20 is fixedly connected to the other side of the limiting block 17. The rubber pad 20 is five millimeters thick. The first slot 18 is located on the inner side close to the rubber pad 20. The other side of the rubber pad 20 is in contact with one side of the sealing block 25. Due to the presence of the rubber pad 20, the sealing block 25 will be pressed when the first locking block 23 is engaged. After the second locking block 24 is engaged, the rebound of the rubber pad 20 can make the second locking block 24 engage more tightly, thereby further improving the stability of the second locking block 24 position engagement.

[0026] refer to Figures 1 to 5 A positioning block 8 is fixedly connected to the top of the base plate 6. A positioning groove 15 matching the positioning block 8 is opened at the bottom end of the first concrete sleeve 10. The positioning block 8 is snapped into the inside of the positioning groove 15. A sealing ring 9 is fixedly connected to the top of the base plate 6. The positioning block 8 is located on the inside of the sealing ring 9. A sealing groove 16 matching the sealing ring 9 is opened at the bottom end of the first concrete sleeve 10. The sealing ring 9 covers the inside of the sealing groove 16. When the concrete is poured and a shear wall is formed, the user can first adjust the second locking block 24 to match the second locking groove 15. 9. At the corresponding angle, the first locking block 23 is pulled out directly to separate the first limiting frame 1 and the second limiting frame 3. Then, the first concrete shell 10 and the second concrete shell 12 are pulled upward by the locking principle of the positioning block 8 to pull out the positioning block 8. At the same time, it is also convenient for the user to separate the first concrete shell 10 and the second concrete shell 12 by the sleeve principle of the movable plate 11. In this way, the outer shell structure of the entire device can be disassembled to facilitate subsequent inspection and maintenance of the concrete shear wall.

[0027] refer to Figure 1 The first limiting frame 1 and the second limiting frame 3 are both fixedly connected to the outer side of the fixing plate 4. The top of the fixing plate 4 is provided with a positioning hole 5, which penetrates the fixing plate 4. Because of the positioning hole 5, the user can use a positioning part that matches the positioning hole 5 to fix the position of the fixing plate 4, thereby effectively improving the stability of the first limiting frame 1 in position installation.

[0028] refer to Figure 1 The first concrete casing 10 and the second concrete casing 12 are both provided with a strip-shaped opening 13 on the front side. A transparent glass 14 is fixedly connected to the inside of the strip-shaped opening 13. The transparent glass 14 covers the inside of the strip-shaped opening 13.

[0029] refer to Figure 1The outer walls of the first concrete casing 10 and the second concrete casing 12 are coated with an anti-corrosion layer. The anti-corrosion layer on the outer walls of the first concrete casing 10 and the second concrete casing 12 is made of epoxy resin material. Due to the presence of the anti-corrosion layer, the corrosion resistance of the outer walls of the first concrete casing 10 and the second concrete casing 12 can be effectively improved, thereby effectively improving the service life of the first concrete casing 10 and the second concrete casing 12.

[0030] refer to Figure 5 The connecting frame 7 has an internal reinforcing layer with a thickness of two centimeters. The internal reinforcing layer of the connecting frame 7 is made of aluminum alloy. Due to the presence of the reinforcing layer, the overall structural strength of the connecting frame 7 can be effectively improved, and the stability of the concrete shear wall can be effectively improved.

[0031] Operating principle and advantages: In use, the second locking block 24 is inserted into the circular groove 21, and then the second locking block 24 is adjusted to a non-corresponding angle with the second locking groove 19, so that the second locking block 24 can be locked into the circular groove 21, so that the first limiting frame 1 and the first concrete sleeve 10 form a whole. It also facilitates the user to pour concrete by reinforcing it with the connecting frame 7. If the width of the overall device deviates slightly from the expected width, the user can pull the first limiting frame 1 through the sleeved movable frame 2. The first limiting frame 1 can drive the first concrete sleeve 10. The shell 10 moves together, thus extending the overall device and effectively solving the inconvenience caused by the inability to adjust the width of the overall device. Due to the presence of the retaining spring 22, its engagement can further limit the position of the second retaining block 24, thereby improving the stability of the engagement of the second retaining block 24 and also effectively improving the stability of the engagement of the first concrete shell 10. Due to the presence of the rubber pad 20, when the first retaining block 23 is engaged, the sealing block 25 is pressed; after the second retaining block 24 is engaged, the rebound of the rubber pad 20 allows... The second locking block 24 engages more tightly, further improving the stability of the locking position. When the concrete is poured and a shear wall is formed, the user can first adjust the second locking block 24 to the corresponding angle with the second locking slot 19, and then directly pull out the first locking block 23 to separate the first limiting frame 1 and the second limiting frame 3. Then, the first concrete sleeve 10 and the second concrete sleeve 12 are pulled upwards by the locking principle of the positioning block 8 to pull out the positioning block 8. At the same time, it is also convenient for the user to separate the first concrete sleeve 10 and the second concrete sleeve 12 by the sleeve principle of the movable plate 11, so that the outer shell structure of the entire device can be disassembled to facilitate subsequent inspection and maintenance of the concrete shear wall. Due to the opening of the positioning hole 5, the user can use the positioning part that matches the positioning hole 5 to fix the position of the fixing plate 4, thereby effectively improving the stability of the first limiting frame 1 position installation. Due to the opening of the strip opening 13, the user can observe the concrete pouring status at all times through the transparent glass 14, which can effectively improve the safety of concrete pouring.
