Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a prefabricated shear wall vertical grouting sleeve connection structure. Background Technology

[0002] Shear walls, also known as wind-resistant walls, earthquake-resistant walls, or structural walls, are walls in buildings or structures that primarily bear horizontal and vertical loads caused by wind loads or earthquakes. In recent years, with the rapid development of prefabricated buildings, the vertical connection structure of prefabricated shear walls is a key factor affecting the safety and construction speed of prefabricated buildings.

[0003] For example, a Chinese patent (publication number: CN209163232U) discloses a prefabricated shear wall vertical grouting sleeve connection structure, including an upper shear wall, a floor slab, and a lower shear wall. The upper and lower shear walls contain vertical reinforcing bars. The reinforcing bars of the upper shear wall extend out of the bottom surface of the wall to form insert bars. A sleeve is fixed to the top of the internal reinforcing bars of the lower shear wall. The lower part of the sleeve is located within the lower shear wall, while the upper part is exposed outside the lower shear wall. The elevation of the top of the sleeve is equal to the elevation of the upper surface of the floor slab at the connection structure. A joint filled with grout is provided between the upper shear wall and the upper surface of the floor slab. This device grouts the sleeve before connecting the insert bars, and the fullness of the sleeve can be visually observed, avoiding the problem of incomplete grouting.

[0004] This patent proposes a prefabricated shear wall vertical grouting sleeve connection structure to solve the above-mentioned problems by grouting the sleeve before inserting the reinforcing bars and visually judging whether the grouting of the sleeve is full. However, air bubbles may still appear in the sleeve, resulting in insufficient grouting. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated shear wall vertical grouting sleeve connection structure, including a cylinder body, with a lower rib and an upper rib extending into its inner cavity respectively movably connected to the bottom and top of the cylinder body, a grouting port fixedly connected to the right side of the cylinder body, an outlet fixedly connected to the top of the cylinder body, a rotating rod rotatably connected to the right side of the cylinder body, penetrating into the inner cavity of the cylinder body and movably connected to the left side wall of the inner cavity, a turntable fixed to the right side of the rotating rod, a displacement member located in the inner cavity of the cylinder body threadedly connected to the outer side of the rotating rod, a connecting plate fixedly connected to the rear side wall of the inner cavity of the cylinder body, a pressing member extending into its inner cavity and located outside the upper rib at the top of the cylinder body, and spring members fixed to the pressing member on the inner bottom surface of both the left and right side walls of the cylinder body, the spring members being fixed to the cylinder body;

[0009] Furthermore, the top of the pressure plate has a movable opening that extends to its bottom, and the upper rib is slidably connected to the pressure plate through the movable opening. The pressure plate has multiple material passage holes.

[0010] By adopting this technical solution, the movement of the pressure plate is facilitated, which in turn helps the components to achieve the effect of compacting the upper and lower parts of the sleeve.

[0011] Furthermore, sliding channels are provided on both the left and right sides of the inner cavity wall of the cylinder, the movable block is slidably connected to the cylinder through the sliding channels, and the elastic element is located inside the sliding channels.

Two connecting plates are fixed to the bottom of the connecting block in a symmetrical arrangement. The two connecting plates are fixed to the fixing block, which has a frustum structure.

[0014] By adopting this technical solution, it is beneficial to uniformly distribute the grout on both sides of the sleeve through the structural setting of the fixed block, thereby improving the uniformity of grouting inside the sleeve.

[0016] By adopting this technical solution, the stable displacement of the connecting plate is facilitated, which in turn helps to limit the displacement component, thereby enabling the lateral displacement of the displacement component and improving the stability of the structure.

[0017] Furthermore, the spring-loaded component includes a fixed cylinder, a spring-loaded spring, and a displacement column. The fixed cylinder is located within the sliding channel and fixed to the side wall of the cylinder body. The spring-loaded spring is fixed to the inner bottom wall of the fixed cylinder. The displacement column is fixed to the top of the spring-loaded spring and extends to the outside of the fixed cylinder. The top of the displacement column is fixed to the movable block.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1 The prefabricated shear wall vertical grouting sleeve connection structure in this embodiment includes a cylinder 1. The bottom and top of the cylinder 1 are respectively movably connected to a lower rib 2 and an upper rib 3 extending into its inner cavity. The top and bottom of the cylinder 1 are provided with insertion interfaces, and the upper and lower insertion interfaces are respectively inserted into the upper rib 3 and the lower rib 2.

[0032] It is understandable that the insertion interface facilitates the connection between the upper rib 3 and the lower rib 2 and the cylinder 1, thereby improving the assembly efficiency of the wall, thus improving the construction efficiency, and ultimately enhancing the structural performance.

[0033] It is also understandable that a rotating rod 6 is rotatably connected to the right side of the cylinder 1, penetrating into the inner cavity of the cylinder 1 and movably connected to the left side wall of the inner cavity. A turntable 7 is fixed to the right side of the rotating rod 6, and a displacement member 8 located in the inner cavity of the cylinder 1 is threadedly connected to the outer side of the rotating rod 6.

[0034] It should be noted that by setting up the displacement component 8, it is beneficial to drive the displacement component 8 to move by rotating the rotating rod 6, thereby achieving uniform distribution of the slurry in the left and right sides of the cylinder 1, which is beneficial to improving the overall structural performance and thus improving construction quality and efficiency.

[0035] It should also be noted that the displacement member 8 is fixed with a connecting plate 9 that is movably connected to the rear side wall of the inner cavity of the cylinder 1. The top of the cylinder 1 is provided with a pressing member 10 that extends into its inner cavity and is located outside the upper rib 3. The inner bottom surfaces of the left and right side walls of the cylinder 1 are provided with spring members 11 that are fixed to the pressing member 10. The spring members 11 are fixed to the cylinder 1.

[0036] It should be noted that the setting of the elastic element 11 is beneficial to support the pressing element 10, thereby improving the reset efficiency of the pressing element 10, which in turn facilitates continuous pressing of the slurry, thereby improving the convenience of the structure and the effect of the structure.

[0037] Please see Figure 2 In order to achieve uniformity of the slurry in the sleeve, the displacement member 8 in this embodiment includes a connecting block 801, two connecting plates 802 and a fixing block 803. The connecting block 801 is threadedly connected to the outer side of the rotating rod 6. Two connecting plates 802 arranged symmetrically in front and behind are fixed at the bottom of the connecting block 801. The top of the connecting block 801 is fixed to the connecting plate 9. A moving block is fixed on the back of the connecting plate 9.

[0038] It can be seen that by setting up the moving block, it is beneficial to make sliding connections between the moving block and the moving channel, which helps to improve the stability of the overall component and thus the overall structural stability.

[0039] It can also be seen that a slide is fixed between the left and right side walls of the inner cavity of the cylinder 1. A moving channel is opened on the front of the slide. The moving block is slidably connected to the cylinder 1 through the moving channel. The front and rear connecting plates 802 are fixed to the fixed block 803. The fixed block 803 is a frustum structure.

[0040] In this embodiment, the structure of the fixing block 803 facilitates the displacement of the fixing block 803, causing the grout on the right side to slide to the left, thereby improving the uniformity of the grout on both sides of the sleeve and thus enhancing the uniformity of grouting in the sleeve. The rotation of the turntable 7 drives the rotating rod 6 to rotate, which in turn drives the connecting block 801 to rotate through the thread action. The limiting effect of the connecting plate 9 on the connecting block 801 enables the displacement of the connecting block 801, thereby facilitating the left and right displacement of the fixing block 803. This facilitates the manipulation of the left and right grout at the beginning of grouting, thus improving the uniformity of the grout on both sides of the sleeve and ultimately enhancing the overall structural performance.

[0041] Please see Figure 3 To ensure full filling of the slurry, the pressing component 10 in this embodiment includes two movable columns 1001, a collar 1002, a pressure plate 1003, and two movable blocks 1004. The movable columns 1001 are slidably connected to the top of the cylinder 1 and extend into its inner cavity. The collar 1002 is fixed to the top of the movable columns 1001 and is located outside the upper rib 3. The pressure plate 1003 is fixed to the bottom of the movable columns 1001 and is movably connected to the upper rib 3 through it. The top of the pressure plate 1003 has an movable opening that extends to its bottom.

[0042] It is easy to understand that the setting of the movable port facilitates the displacement of the upper rib 3, which in turn facilitates the up-and-down movement of the pressure plate 1003, thereby achieving uniform pressing of the slurry from top to bottom, which in turn facilitates the compaction of the slurry in the sleeve, thus improving the uniformity of the slurry.

[0043] It is not difficult to understand that the upper rib 3 is slidably connected to the pressure plate 1003 through the movable port. The pressure plate 1003 has multiple material passage holes. The movable block 1004 is fixed to the outside of the pressure plate 1003. The two movable blocks 1004 extend into the left and right side walls of the inner cavity of the cylinder 1 respectively, and the movable shaft of the spring member 11 is fixed. Sliding channels are provided on both the left and right sides of the inner cavity wall of the cylinder 1. The movable block 1004 is slidably connected to the cylinder 1 through the sliding channel, and the spring member 11 is located in the sliding channel.

[0044] In this embodiment, the sliding channel facilitates the displacement of the movable block 1004, thereby improving the stability of the pressure plate 1003 displacement, which in turn facilitates continuous pressing of the slurry, thereby improving the fullness of the slurry in the sleeve, and thus facilitating sufficient grouting in the sleeve.

[0045] Please see Figure 4 To improve ease of use, the spring 11 in this embodiment includes a fixed cylinder 1101, a spring 1102, and a displacement column 1103. The fixed cylinder 1101 is located in the sliding channel and fixed in the side wall of the cylinder 1. The spring 1102 is fixed to the inner bottom wall of the fixed cylinder 1101.

[0046] It should be noted that the spring 1102 helps to support the displacement column 1103, which in turn helps to support the pressure plate 1003, thus facilitating the reset of the pressure plate 1003, ensuring the stable use of the pressing component 10, and ultimately improving the overall structural stability.

[0047] It should also be noted that the top of the displacement column 1103 is fixed to the top of the spring spring 1102 and extends to the outside of the fixed cylinder 1101. The top of the displacement column 1103 is fixed to the movable block 1004. The top of the fixed cylinder 1101 has an opening, and the displacement column 1103 is slidably connected to the fixed cylinder 1101 through the opening.

[0048] In this embodiment, the opening facilitates the movement of the displacement column 1103. The spring 1102 provides a supporting force to the displacement column 1103, which in turn supports the pressure plate 1003, enabling the pressure plate 1003 to quickly reset. This facilitates rapid pressing of the grout, ensuring sufficient and full grout in the sleeve, thus improving the grouting quality within the sleeve, and ultimately contributing to the stable use of the overall component and the overall structure.

[0049] The working principle of the above embodiments is as follows:

[0050] By connecting the bottom insertion port of cylinder 1 to the lower reinforcing bar 2, and then connecting the upper reinforcing bar 3 of the shear wall to the top insertion port, the sleeve is sealed. Grout is introduced into cylinder 1 through the inlet 4 connected to the conduit. Simultaneously, the rotating rod 6 can be rotated via the turntable 7. The limiting effect of the connecting plate 9 and cylinder 1 allows the connecting block 801 to move, thereby causing the fixing block 803 to move left and right. The structural design of the fixing block 803 facilitates the pushing of grout from the inlet 4 to the left, thus promoting saturation of the grout on the left side of cylinder 1. When the grout fills to the bottom of the pressure plate 1003, hold the collar 1002 and press the entire pressure plate 1003 downward. Through the contact of the pressure plate 1003 with the grout, the grout in the cylinder 1 is compacted, which helps to improve the fullness of the grout in the cylinder 1. Through the supporting effect of the spring spring 1102 on the displacement column 1103, the collar 1002 is lifted, which helps to reset the pressure plate 1003, improves the convenience of compaction work, and improves the overall structure's performance. The overall structure is simple and helps to prevent insufficient grouting of the sleeve.
