Description

Technical Field

[0001] This invention relates to the field of station component connection technology, and in particular to a grouting auxiliary device for prefabricated metro station components. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, subway station components, etc.) are processed and manufactured in factories, transported to the construction site (such as a subway station under construction), and assembled and installed on-site using reliable connection methods.

[0003] After the station components are installed on the base, grout needs to be poured between the station components and the base to better connect the station components to the base. However, after the grouting is completed, because the grout is poured on later and the filling density of the grout cannot be well controlled, the connection between the station components and the base is not very firm and there is a risk of falling off. Summary of the Invention

[0004] This invention provides a grouting auxiliary device for prefabricated subway station components to solve the technical problem of weak connection between station components and base.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] This invention provides a grouting auxiliary device for prefabricated subway station components, comprising:

[0007] The guiding mechanism includes multiple insert rods and multiple guide sleeves that are respectively matched with the multiple insert rods; the multiple insert rods are vertically slidably connected to multiple first grouting grooves opened at the bottom of the external station component, and the multiple guide sleeves are vertically installed on the top of the external base;

[0008] The first grouting groove of the station component has multiple grout outlet holes at the top and a second grouting groove at the bottom;

[0009] The top of the base has multiple grouting holes that connect to the grouting pipe of the grouting equipment;

[0010] The auxiliary feeding mechanism includes a feeding pipe, a guide pipe connected to the bottom of the feeding pipe, and a pusher assembly installed on the guide pipe to push out the excess material in the guide pipe; the end of the guide pipe away from the feeding pipe is connected to the slurry outlet.

[0011] Furthermore, the guide pipe is connected to the slurry outlet in an upward-sloping manner, and the inclination angle between the guide pipe and the station component is 20 to 60 degrees.

[0012] The feed tube is made of transparent material, and its surface is equidistantly marked with graduations for reading the volume of grout material inside the feed tube.

[0013] Furthermore, the feeding assembly includes:

[0014] The rotating rod is partially threaded into a threaded hole at the top of the feed tube and extends into the inside of the feed tube.

[0015] A removal block is installed at the end of a rotating rod, and the rotating rod has a blade on the side facing the station components for removing grout material remaining on the inner wall of the guide pipe;

[0016] The lever is vertically mounted on a rotating rod on the outside of the feed tube.

[0017] Furthermore, the rejection block is detachably mounted on the rotating rod;

[0018] The detachable method is a threaded connection, with the threads between the ejector block and the rotating rod reversed from the threads between the rotating rod and the guide tube.

[0019] Furthermore, the grouting auxiliary device also includes a plurality of elastic compression mechanisms respectively installed in a plurality of first grouting grooves, the elastic compression mechanism comprising:

[0020] A fixing block is fixedly installed on the bottom of the first grouting groove on the station component; the top of the fixing block has an installation hole;

[0021] The movable ring is slidably connected to the outer ring of the insert rod, and the inner ring of the movable ring abuts against the outer wall of the insert rod; the outer ring of the movable ring abuts against the inner wall of the mounting hole opened on the top of the fixed block, and the distance between the outer ring of the movable ring and the inner wall of the first grouting groove is greater than 6mm.

[0022] The tension spring has its bottom fixedly connected to the fixed block, and its top fixedly connected to the bottom surface of the movable ring.

[0023] Furthermore, the outer ring of the movable ring and the inner wall of the mounting hole of the fixed block are configured as mutually matching bevels.

[0024] Furthermore, the grouting auxiliary device also includes multiple locking mechanisms, the locking mechanisms including:

[0025] A limiting ring is fixedly installed on the top of the guide sleeve. The axis of the limiting ring is coaxial with the axis of the guide sleeve, and the inner diameter of the limiting ring is smaller than the inner diameter of the guide sleeve.

[0026] The guide block is shaped like a frustum and is placed on the inner bottom surface of the guide sleeve;

[0027] The snap-fit ​​block includes a connecting part and a deformable part. The deformable part is vertically installed at the bottom of the plug rod through the connecting part. The position of the deformable part is matched with the position of the guide block. When the station component is installed on the base, the deformable part extends into the guide sleeve, and the bottom of the deformable part is deformed by means of the guide block, so that the plug rod is snapped into the guide sleeve.

[0028] Furthermore, the outer surface of the connecting part is provided with a plurality of first through holes to facilitate the flow of grout.

[0029] Furthermore, the transverse cross-section of the deformable part is in the shape of two C-shaped halves, and the surface of the deformable part is provided with multiple second through holes.

[0030] Furthermore, the material of the deformable part is one of Q215, Q235, No. 25 steel, and No. 45 steel, and the wall thickness of the deformable part is 2~4mm.

[0031] The beneficial effects of this invention are:

[0032] 1. The present invention installs multiple insert rods at the bottom of the station component and sets multiple guide sleeves at the top of the base. The number of insert rods and guide sleeves are equal and correspond to each other. The insert rods and guide sleeves can be used for positioning and guidance, which can improve the positioning accuracy of the station component and the base during the docking process and reduce the time consumed for positioning.

[0033] 2. This invention includes an auxiliary material replenishment mechanism, which comprises a feeding pipe, a transparent guide pipe, and a pushing component. The feeding pipe is used to add grout to the grout outlet. The guide pipe is used to observe the filling status of the grout between the station components and the base in real time. After filling is completed, the grout will overflow through the guide pipe. Construction personnel can stop filling when they see this, which is convenient and practical. At the same time, this design can also make the density of the grout between the station components and the base higher. The pushing component is used to push out the grout filled and residual in the guide pipe for future use, thereby improving the utilization rate of the auxiliary material replenishment mechanism.

[0034] 3. This invention provides multiple locking mechanisms between the station components and the base. Each locking mechanism is located between the corresponding insert rod and the corresponding guide sleeve. When the deformable part is fully inserted into the inner side of the guide sleeve, the deformable part will contact the frustum-shaped guide block located at the bottom of the guide sleeve. Under the pressure of the guide block, the bottom of the deformable part will roll outwards until the outwardly rolled part of the deformable part abuts against the limiting ring. Since the inner diameter of the limiting ring is smaller than the inner diameter of the guide sleeve, the limiting ring can limit the position of the deformable part, the insert rod, and even the entire station component after the deformable part is deformed. At the same time, after the grout is poured and the grout is completely solidified, the solidified grout can make the deformable part, the entire insert rod, and even the entire station component more firmly installed on the base due to the outward rolling of the deformable part, which improves the connection strength between the station component and the base and makes the entire underground structure safer and more reliable.

[0056] Reference Figure 1 , Figure 5 and Figure 7 This application provides a grouting auxiliary device for prefabricated subway station components, comprising:

[0057] The guiding mechanism 1 includes multiple insert rods 11 and multiple guide sleeves 12 that are respectively matched with the multiple insert rods 11; the multiple insert rods 11 are vertically slidably connected to multiple first grouting grooves 21 opened at the bottom of the external station component 2, and the multiple guide sleeves 12 are vertically installed on the top of the external base 3.

[0058] The top surface of the base 3 is provided with multiple fixing grooves for installing the guide sleeve 12. The top surface of the guide sleeve 12 is flush with the top surface of the fixing groove, and the outer side of the guide sleeve 12 abuts against the inner wall of the fixing groove. This design can effectively prevent the guide sleeve 12 from bending and deforming.

[0059] Alternatively, the guide sleeve 12 can be directly and vertically fixed to the top of the base 3, with the top surface of the guide sleeve 12 flush with the top surface of the base 3. When the base 3 is cast by mold, the guide sleeve 12 can be pre-installed in the mold of the base 3, and the guide sleeve 12 and the base 3 can be cast as one piece. This design does not require the opening of a fixing groove, reducing processing costs. At the same time, it can make the connection between the guide sleeve 12 and the base 3 more secure. Since the top surface of the guide sleeve 12 is flush with the top surface of the base 3, it can also facilitate transportation and reduce transportation space.

[0060] The guide sleeve 12 is in the shape of a round tube, and the thickness of one side of the guide sleeve 12 is 5~155mm; to avoid the guide sleeve 12 being too thin, causing the insertion rod 11 installed on the station component 2 to be damaged or deformed during the positioning and docking process with the guide sleeve 12 installed on the base 3.

[0061] The first grouting groove 21 of the station component 2 has a grout outlet 22 at the top and a second grouting groove 23 at the bottom;

[0062] The top of the base 3 is provided with a grouting hole 31 that is connected to the grouting pipe of the grouting equipment;

[0063] Reference Figure 8The auxiliary feeding mechanism 4 includes a feeding pipe 41, a guide pipe 42 connected to the bottom of the feeding pipe 41, and a pusher assembly 43 installed on the guide pipe 42 for pushing out the remaining material in the guide pipe 42; the end of the guide pipe 42 away from the feeding pipe 41 is connected to the slurry outlet 22.

[0064] The number of auxiliary feeding mechanisms 4 can be one or more. In this embodiment, the number of auxiliary feeding mechanisms 4 is equal to the number of slurry outlet holes 22 and they correspond to each other. The guide pipe 42 on each auxiliary feeding mechanism 4 is connected to the corresponding slurry outlet hole 22.

[0065] In use, the station component 2 to be installed is first hoisted onto the base 3 using hoisting equipment. Multiple insertion rods 11 on the station component 2 face the corresponding guide sleeves 12 at the top of the base 3. During the docking of the station component 2 and the base 3, the insertion rods 11 partially extend into the inner side of their respective guide sleeves 12 under the influence of gravity. By adjusting the position of the station component 2, the insertion rods 11 can be fully inserted into their respective guide sleeves 12. During this process, the insertion rods 11 can be used for positioning and guidance, improving the positioning accuracy of the station component 2 and the base 3 during docking.

[0066] After the station component 2 is installed on top of the base 3, the guide pipes 42 on the multiple auxiliary material supply mechanisms 4 are respectively installed in the corresponding grout outlet holes 22. Then, the grouting equipment is started to fill the grouting material through one of the grouting holes 31, and the other grouting holes 31 are plugged with rubber stoppers. The filled grouting material flows into the multiple first grouting grooves 21 through the second grouting groove 23 and fills the multiple first grouting grooves 21 until the filled grouting material flows into the designated position of the guide pipe 42 through the grout outlet hole 22. Then, the filling of grouting material is stopped. After standing for a certain period of time (such as 10 to 15 minutes), the filled grouting material falls back between the station component 2 and the base 3. When it is necessary to continue filling grouting material, grouting material can be added to the corresponding grout outlet hole 22 through the feeding pipes 41 on the multiple auxiliary material supply mechanisms 4. The present invention has a simple structure and is convenient and practical.

[0067] In some embodiments, the guide pipe 42 is connected to the slurry outlet 22 in an upward-sloping manner, and the inclination angle between the guide pipe 42 and the station component 2 is 20 to 60 degrees.

[0068] The guide tube 42 is made of transparent material, allowing construction personnel to easily observe the amount of grout overflowing inside the guide tube 42 in real time. The surface of the guide tube 42 is equidistantly marked with graduations for reading the volume of grout inside.

[0069] In some embodiments, refer to Figure 1 and Figure 8The feeding assembly 43 includes:

[0070] The rotating rod 431 is partially threaded into the threaded hole at the top of the guide tube 42 and extends into the inside of the guide tube 42.

[0071] The removal block 432 is installed at the end of the rotating rod 431. The rotating rod 431 has a blade on the side facing the station component 2 for removing grout material remaining on the inner wall of the guide pipe 42.

[0072] The lever 433 is vertically mounted on the rotating rod 431 on the outside of the guide tube 42.

[0073] When in use, when construction workers need to push the grouting material in the guide pipe 42 into the grout outlet 22, or need to push out the residual grouting material in the guide pipe 42, they can rotate the lever 433, which will simultaneously drive the rotating rod 431 to rotate. Since the rotating rod 431 and the guide pipe 42 are connected by a thread, when rotating the rotating rod 431, the removal block 432 can be pushed to move in a spiral shape towards the station component 2. During the movement, the (filled or residual) grouting material in the guide pipe 42 can be pushed outward, avoiding the impact of residual grouting material in the guide pipe 42 on the next use of the auxiliary material replenishing mechanism 4, thus improving the utilization rate of the auxiliary material replenishing mechanism 4.

[0074] In some embodiments, the rejection block 432 is detachably mounted on the rotating rod 431;

[0075] The detachable connection is a threaded connection. The threads between the removal block 432 and the rotating rod 431 are reversed with the threads between the rotating rod 431 and the guide tube 42. This detachable connection makes it easy for construction personnel to replace the removal block 432 and facilitates later maintenance and upkeep.

[0076] In some embodiments, refer to Figures 4 to 6 The grouting auxiliary device further includes a plurality of elastic compression mechanisms 5 respectively installed in a plurality of first grouting grooves 21, the elastic compression mechanism 5 comprising:

[0077] The fixing block 51 is fixedly installed on the bottom of the first grouting groove 21 on the station component 2; the top of the fixing block 51 is provided with an installation hole;

[0078] The movable ring 52 is slidably connected to the outer ring of the insert rod 11, and the inner ring of the movable ring 52 abuts against the outer wall of the insert rod 11; the outer ring of the movable ring 52 abuts against the inner wall of the mounting hole opened on the top of the fixing block 51, and the distance between the outer ring of the movable ring 52 and the inner wall of the first grouting groove 21 is greater than 6mm.

[0079] The bottom of the tension spring 53 is fixedly connected to the fixed block 51, and the top of the tension spring 53 is fixedly connected to the bottom surface of the movable ring 52.

[0080] When grout is filled into the grouting hole 31 through the grouting equipment, the movable ring 52 continuously compacts the grout at the bottom of the first grouting groove 21 under the action of the tension spring 53, so as to increase the density of the grout. The tension of the tension spring 53 can be selected according to actual needs so that the density of the grout at the bottom of the first grouting groove 21 meets the set requirements.

[0081] In some embodiments, the outer ring of the movable ring 52 and the inner wall of the mounting hole of the fixing block 51 are configured as mutually matching bevels.

[0082] In some embodiments, the grouting auxiliary device further includes a plurality of locking mechanisms 6, the locking mechanism 6 comprising:

[0083] A limiting ring 61 is fixedly installed on the top of the guide sleeve 12. The axis of the limiting ring 61 is coaxial with the axis of the guide sleeve 12, and the inner diameter of the limiting ring 61 is smaller than the inner diameter of the guide sleeve 12.

[0084] The guide block 62 is frustum-shaped and is placed on the inner bottom surface of the guide sleeve 12;

[0085] The snap-fit ​​block 63 includes a connecting part 631 and a deformable part 632. The deformable part 632 is vertically installed at the bottom of the plug rod 11 through the connecting part 631. The position of the deformable part 632 is matched with the position of the guide block 62. When the station component 2 is installed on the base 3, the deformable part 632 extends into the guide sleeve 12, and the bottom of the deformable part 632 is deformed by means of the guide block 62, so that the plug rod 11 is snapped into the guide sleeve 12.

[0086] During the docking process between station component 2 and base 3, multiple insert rods 11 are fully inserted into their respective guide sleeves 12. The deformable portions 632 on the multiple insert rods 11 are respectively fitted onto the outer side of their respective guide blocks 62. The guide blocks 62 are frustoconical in shape. Under the pressure of the guide blocks 62, the deformable portions 632 deform, causing the expanded diameter of the deformed portions 632 to be larger than the inner diameter of the limiting ring 61. Since the deformable portions 632 are fixedly installed at the bottom of the insert rods 11 via the connecting portion 631, the deformation of the deformable portions 632 is limited... When the rod is contained within the limiting ring 61, the entire insertion rod 11 will also be contained within the limiting ring 61. This design allows the station component 2 to be installed more securely on the base 3. At the same time, after the grout is poured and the grout has completely solidified, the deformable part 632 rolls outward. The solidified grout allows the deformable part 632 and the entire insertion rod 11, and even the entire station component 2, to be installed more securely on the base 3, which improves the connection strength between the station component 2 and the base 3, making the entire underground structure safer and more reliable.

[0087] In some embodiments, the outer surface of the connecting part 631 is provided with a plurality of first through holes to facilitate the flow of grout. After the grout has completely solidified, the connecting part 632 can be more firmly fixed to the base 3 because the grout passes through the first through holes.

[0088] In some embodiments, the transverse cross section of the deformable part 632 is two C-shaped halves, and the surface of the deformable part 632 is provided with a plurality of second through holes. The second through holes can also facilitate the penetration of grouting material. After the grouting material has completely solidified, the deformable part 632 can be more firmly fixed on the base 3.

[0089] In some embodiments, the material of the deformable part 632 is one of Q215, Q235, No. 25 steel, and No. 45 steel, and the wall thickness of the deformable part 632 is 2~4mm.

[0090] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
