Description

Technical Field

[0001] This application relates to the field of diaphragm wall construction, and in particular to a device for quickly aligning the vertical connection of the main reinforcement bars of a diaphragm wall steel reinforcement cage. Background Technique

[0002] The diaphragm wall project is a very important part of the construction project. Especially in the foundation project, the diaphragm wall not only increases the structural stability of the building, but also has multiple functions such as water cutoff, anti-seepage, load-bearing, and water retaining.

[0003] At the present stage, during the construction of pile foundations and diaphragm walls in underground projects, it is usually necessary to vertically connect two steel reinforcement cages. After the main reinforcement bars of the steel reinforcement cages are vertically connected, fasteners are used to achieve the stable connection between the main reinforcement bars of the two steel reinforcement cages.

[0004] In view of the above-mentioned prior art, during the connection of two steel reinforcement cages, due to the small size of the main reinforcement bars of the steel reinforcement cages, it is often necessary to adjust the position of the top steel reinforcement cage multiple times to achieve the alignment of the positions of the two steel reinforcement cages, resulting in a low installation efficiency of the steel reinforcement cages. Utility Model Content

[0005] In order to facilitate the quick alignment of the position during the installation of the steel reinforcement cage and improve the installation efficiency of the steel reinforcement cage, this application provides a device for quickly aligning the vertical connection of the main reinforcement bars of a diaphragm wall steel reinforcement cage.

[0006] The device for quickly aligning the vertical connection of the main reinforcement bars of a diaphragm wall steel reinforcement cage provided by this application adopts the following technical solutions:

[0007] A device for quickly aligning the vertical connection of the main reinforcement bars of a diaphragm wall steel reinforcement cage includes a connecting sleeve and a guiding sleeve. The connecting sleeve is in threaded cooperation with the ends of the main reinforcement bars of two adjacent steel reinforcement cages in the vertical direction. The guiding sleeve includes a guiding part and a connecting part. The guiding part is fixedly installed on the top of the connecting part. The guiding part has a guiding opening, and the opening size of the guiding opening gradually increases from the end close to the connecting part to the end far from the connecting part. The connecting part is detachably installed on the connecting sleeve.

[0008] By adopting the above technical solution, when it is necessary to connect the main bars of two adjacent steel reinforcement cages during the construction of the diaphragm wall, first install the connecting sleeve on the top of the main bars of the bottom steel reinforcement cage, and then install the guiding sleeve on the connecting sleeve. The guiding opening of the guiding sleeve plays a guiding role in the installation of the main bars of the top steel reinforcement cage and the main bars of the bottom steel reinforcement cage, so as to facilitate the rapid installation of the main bars of the top steel reinforcement cage to a position directly opposite to the main bars of the bottom steel reinforcement cage. At this time, apply force to rotate the guiding sleeve so that the connecting sleeve realizes the thread fit with the top steel reinforcement cage and the bottom steel reinforcement cage, and the stable connection between the main bars of the two adjacent steel reinforcement cages can be achieved. During the installation of the two steel reinforcement cages, the main bars of the top steel reinforcement cage can be guided through the guiding opening, and there is no need to repeatedly adjust the position of the top steel reinforcement cage, so as to facilitate the rapid alignment of the positions of the two steel reinforcement cages during installation, which is beneficial to improving the installation efficiency between the two steel reinforcement cages; in addition, when connecting sleeves and guiding sleeves are installed on the main bars of each steel reinforcement cage, it is convenient to synchronously align the upper and lower parts of the main bars of multiple steel reinforcement cages, and the applicability is strong.

[0009] Optionally, the connecting part includes two connecting half-rings, and the two connecting half-rings are fixed by bolts; the guiding part includes two guiding half-rings, and the two guiding half-rings are respectively fixedly installed on the tops of the two connecting half-rings, and the two guiding half-rings are fixed by bolts.

[0010] By adopting the above technical solution, the method of fixing the two connecting half-rings by bolts makes the disassembly and assembly structure between the connecting part and the connecting sleeve simple and convenient to operate. In addition, the setting of the two guiding half-rings enables the disassembly of the guiding sleeve from the left and right sides of the main bars of the steel reinforcement cage after the connection between the connecting part and the connecting sleeve is released, and then it is convenient to realize the repeated cyclic use of the guiding sleeve.

[0011] Optionally, an installation guide block is fixedly installed on one side of one guiding half-ring facing the other guiding half-ring, and an installation guide groove is formed on the side of the other guiding half-ring facing the installation guide block, and the installation guide block and the installation guide groove are in plug-in fit.

[0012] By adopting the above technical solution, the plug-in fit between the installation guide block and the installation guide groove plays a positioning role in the installation of the two guiding half-rings, so as to facilitate the rapid installation of the two guiding half-rings to the position where they are fixed.

[0013] Optionally, when the connecting part is installed on the connecting sleeve, the inner bottom wall of the guiding half-ring abuts against the top of the connecting sleeve, and the diameter of the guiding opening at one end close to the connecting part is equal to the inner diameter of the connecting sleeve.

[0014] By adopting the above technical solution, on the one hand, the connecting sleeve plays a supporting role in the installation of the guiding half-ring, which is convenient for the stable installation between the two guiding half-rings; on the other hand, it is convenient for the guiding opening to more accurately guide the main bars of the top steel reinforcement cage to the position where they are connected to the main bars of the bottom steel reinforcement cage.

[0015] Optionally, wear-resistant pads are fixedly connected to the inner walls of the two connecting half-rings.

[0016] By adopting the above technical solution, the wear-resistant pads are arranged so that when the two connecting half-rings are fixed to the connecting sleeve, it is not easy to cause damage due to friction with the connecting sleeve, which is beneficial to ensuring the service life of the connecting sleeve and the guiding sleeve.

[0017] Optionally, a limiting rod is fixedly connected to the outer side wall of the connecting sleeve, and a limiting groove corresponding to the limiting rod and in plug-in fit is formed in the inner wall of one of the connecting half-rings.

[0018] By adopting the above technical solution, the cooperation between the limiting rod and the limiting groove has a further limiting effect when the guiding sleeve drives the connecting sleeve to rotate, which is convenient for further ensuring the stability when the guiding sleeve drives the connecting sleeve to rotate.

[0019] Optionally, a chamfer is provided at one end of the limiting rod away from the connecting sleeve.

[0020] By adopting the above technical solution, the chamfer is arranged so that there is a certain clearance transition when the limiting rod is inserted into the limiting groove, so as to facilitate quickly and stably inserting the limiting rod into the limiting groove.

[0021] Optionally, a rotating handle is fixedly installed on the outer side wall of one of the connecting half-rings.

[0022] By adopting the above technical solution, the rotating handle provides a convenient force application point for applying force to rotate the guiding sleeve, so as to facilitate stably rotating the guiding sleeve.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. During the installation of the two steel reinforcement cages, it is only necessary to guide the main reinforcement bars of the top steel reinforcement cage through the guiding openings, and there is no need to repeatedly adjust the position of the top steel reinforcement cage, so as to facilitate quickly aligning the positions when installing the two steel reinforcement cages, which is beneficial to improving the installation efficiency between the two steel reinforcement cages.

[0025] 2. The arrangement of the two guiding half-rings enables the guiding sleeve to be disassembled from the left and right sides of the main reinforcement bars of the steel reinforcement cage after the connection part is released from the fixation with the connecting sleeve, and thus it is convenient to realize the repeated recycling of the guiding sleeve.

[0026] 3. The wear-resistant pads are arranged so that when the two connecting half-rings are fixed to the connecting sleeve, it is not easy to cause damage due to friction with the connecting sleeve, which is beneficial to ensuring the service life of the connecting sleeve and the guiding sleeve.

Detailed implementation manners

[0032] The following will further elaborate on the present application in conjunction with the attached Figures 1-3 drawings.

[0033] An embodiment of the present application discloses a device for quickly aligning the vertical connection of the main reinforcement bars of a diaphragm wall reinforcement cage. Referring to Figure 1 and Figure 2 , the device for quickly aligning the vertical connection of the main reinforcement bars of a diaphragm wall reinforcement cage includes a connecting sleeve 1 and a guiding sleeve 2. Among them, the connecting sleeve 1 is in the shape of a hollow cylinder, and the inner wall of the connecting sleeve 1 is in threaded cooperation with the end of the main reinforcement bar of the beam adjacent to the vertical direction, so as to realize the stable connection between the main reinforcement bars of two adjacent reinforcement cages through the threaded cooperation between the connecting sleeve 1 and the main reinforcement bars of two adjacent reinforcement cages.

[0034] Continuing to refer to Figure 1 and Figure 2 , the guiding sleeve 2 includes a guiding part 201 and a connecting part 202. Among them, the connecting part 202 is in the shape of a hollow cylinder as a whole, and the guiding part 201 is in the shape of a hollow funnel. The connecting part 202 is detachably installed on the connecting sleeve 1. Specifically, the connecting part 202 includes two connecting semi-rings 2021. A plurality of groups of mounting plates 3 distributed along the vertical direction are fixedly connected to the outer side walls of the two connecting semi-rings 2021. In the embodiment of the present application, two groups of mounting plates 3 are provided, two in each group, and the two mounting plates 3 in each group are circumferentially distributed around the axis of the connecting semi-ring 2021. The two connecting semi-rings 2021 are fixed by a plurality of bolts sequentially passing through the adjacent mounting plates 3 of the two connecting semi-rings 2021. When the connecting sleeve 1 is located between the two connecting semi-rings 2021 and the two connecting semi-rings 2021 are fixed by bolts, the fixation between the two connecting semi-rings 2021, that is, the connecting part 202 and the connecting sleeve 1, is realized.

[0035] Continuing to refer to Figure 1 andFigure 2 , the guiding part 201 includes two guiding semi-rings 2011. The two guiding semi-rings 2011 are respectively integrally and fixedly connected to the tops of the two connecting semi-rings 2021, and the two sides of the two guiding semi-rings 2011 are flush with the two sides of the two connecting semi-rings 2021. The two guiding semi-rings 2011 are also fixed by bolts, and the specific fixing structure between the two guiding semi-ring plates is the same as the fixing structure between the two connecting semi-rings 2021, so it will not be elaborated here. When the two guiding semi-rings 2011 are fixed, the area surrounded by the two guiding semi-rings 2011 forms a guiding opening 4. The opening size of the guiding opening 4 gradually increases from the end close to the connecting part 202 to the end far from the connecting part 202, so as to play a guiding role in the installation of the main bars of the top steel cage and the main bars of the bottom steel cage.

[0036] Refer to Figure 2 and Figure 3 , on one side of one guiding semi-ring 2011 facing the other guiding semi-ring 2011, an installation guide block 5 is fixedly installed. On the side of the other guiding semi-ring 2011 facing the installation guide block 5, an installation guide groove 6 is opened. The installation guide block 5 and the installation guide groove 6 are in plug-in fit. On one side of one connecting semi-ring 2021 facing the other connecting semi-ring 2021, a connecting guide block 7 is fixedly connected. On the side of the other guiding semi-ring 2011 facing the installation guide block 5, a connecting guide groove 8 is opened. The connecting guide block 7 and the connecting guide groove 8 are in plug-in fit. Further, the installation guide block 5 and the connecting guide block 7 are integrally formed, and the installation guide groove 6 and the connecting guide groove 8 are communicated, so as to stably play a guiding and positioning role in the installation of the two connecting semi-rings 2021 and the two guiding semi-rings 2011, and quickly install the two guiding semi-rings 2011 and the two connecting semi-rings 2021 to the position where they are fixed.

[0037] Refer to Figure 1 and Figure 2 , when the two connecting semi-rings 2021, that is, the connecting part 202, are installed on the connecting sleeve 1, the inner bottom walls of the two guiding semi-rings 2011 are both in contact with the top of the connecting sleeve 1, and the diameter of the guiding opening 4 close to the connecting part 202 surrounded by the two guiding semi-rings 2011 is equal to the inner diameter size of the connecting sleeve 1, so as to more accurately guide the main bars of the top steel cage to the position where they are connected to the main bars of the bottom steel cage. At the same time, the connecting sleeve 1 plays a supporting role in the installation of the guiding semi-rings 2011, which is convenient for the stable installation between the two guiding semi-rings 2011.

[0038] Refer to Figure 2 and Figure 3, to prevent the two connecting half-rings 2021 from being worn due to friction with the connecting sleeve 1 when they are fixed to the connecting sleeve 1, thereby ensuring the service life of the connecting sleeve 1 and the guiding sleeve 2, wear-resistant pads 9 are fixedly connected to the inner walls of the two connecting half-rings 2021. The material of the wear-resistant pads 9 is selected as rubber. When the two connecting half-rings 2021 are fixed to the connecting sleeve 1, the wear-resistant pads 9 abut against the outer wall of the connecting sleeve 1.

[0039] Referring to Figure 1 and Figure 2 , two limiting rods 10 circumferentially distributed around the axis of the connecting sleeve 1 are fixedly connected to the outer side wall of the connecting sleeve 1. Limiting grooves 11 corresponding to the limiting rods 10 and in plug-in fit are formed in the inner walls of the two connecting half-rings 2021. The two limiting grooves 11 correspond to the positions of the two limiting rods 10 respectively, so as to play a further limiting role when the guiding sleeve 2 drives the connecting sleeve 1 to rotate through the cooperation of the limiting rods 10 and the limiting grooves 11, thereby fully ensuring the stability when the guiding sleeve 2 drives the connecting sleeve 1 to rotate.

[0040] Continue to refer to Figure 1 and Figure 2 , the limiting groove 11 is arranged as a through groove, so as to visually observe the position where the limiting groove 11 is located. To facilitate the insertion of the limiting rod 10 into the limiting groove 11, a chamfer 12 is provided at the end of the limiting rod 10 away from the connecting sleeve 1, so that there is a certain clearance transition when the limiting rod 10 is inserted into the limiting groove 11. Rotating handles 13 are fixedly installed on the outer side walls of the two connecting half-rings 2021, so as to facilitate applying force to rotate the guiding sleeve 2 as a whole.

[0041] The implementation principle of the vertical connection quick alignment device for the main reinforcement bars of the diaphragm wall reinforcement cage in the embodiment of the present application is as follows: when the main reinforcement bars of two adjacent reinforcement cages need to be connected during the construction of the diaphragm wall, first install the connecting sleeve 1 on the top of the main reinforcement bars of the bottom reinforcement cage, and then install the two connecting half-rings 2021 of the guiding sleeve 2 on the connecting sleeve 1. At this time, the guiding opening 4 formed by enclosing the two guiding half-rings 2011 of the guiding sleeve 2 plays a guiding role when installing the main reinforcement bars of the top reinforcement cage and the main reinforcement bars of the bottom reinforcement cage, so as to facilitate quickly installing the main reinforcement bars of the top reinforcement cage to a position directly opposite to the main reinforcement bars of the bottom reinforcement cage. At this time, by applying force to rotate the guiding sleeve 2 through the rotating handle 13, the connecting sleeve 1 can be threadedly engaged with the top reinforcement cage and the bottom reinforcement cage, and thus the stable connection between the main reinforcement bars of two adjacent reinforcement cages can be realized.

[0042] During the installation process of the two steel bar cages, the main steel bars of the top steel bar cage can be guided through the guiding port 4, and there is no need to repeatedly adjust the position of the top steel bar cage, so as to facilitate the quick alignment of the positions of the two steel bar cages during installation, which is beneficial to improving the installation efficiency between the two steel bar cages; moreover, the cooperation of the limiting rod 10 and the limiting groove 11 is beneficial to fully ensure the stability of the guiding sleeve 2 driving the connecting sleeve 1 to rotate; in addition, when the main steel bars of the steel bar cage are all installed with the connecting sleeve 1 and the guiding sleeve 2, it is convenient to synchronously align the upper and lower parts of the main steel bars of multiple steel bar cages, and the applicability is strong.

[0043] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
