Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a sleeve pre-embedding device. Background Art

[0002] During the concrete pouring process of a construction project, embedded pipe fittings need to be pre-installed in multiple areas such as bathrooms, halls, balconies, kitchens, etc., for subsequent pipe penetration and installation. The setting of the embedded pipe fittings helps to ensure that pipes can be smoothly installed during the construction of a building. Therefore, the position and specifications of the embedded pipe fittings need to be accurately positioned and installed according to specific requirements to ensure that the pipes can be installed in the correct position.

[0003] In conventional embedded pipe fittings, the general method is that after the beam steel bars are tied and sunk into the beam frame, the installation constructors pry or knock the stirrups destructively to move them, then put the sleeve into it, and then the installation constructors bend and weld the beam steel bars near the sleeve towards the sleeve direction according to rough memory to fix them. However, this method has large errors, not only damaging the beam stirrups and causing the beam steel bars to be displaced, but also resulting in inconsistent sleeve elevations, not being in a straight line, the pipes being unable to penetrate, and the pipes not being centered.

[0004] The present utility model is studied and proposed in view of the deficiencies of the prior art. Summary of the Utility Model

[0005] In view of the problems in the existing sleeve pre-embedding process mentioned above, that is, the installation constructors bend and weld the beam steel bars near the sleeve towards the sleeve direction according to rough memory to fix them, and there are large errors in measurement and positioning, not only damaging the beam stirrups and causing the beam steel bars to be displaced, but also resulting in inconsistent sleeve elevations, not being in a straight line, the pipes being unable to penetrate, and the pipes not being centered, the technical solution adopted by the present utility model to solve its technical problems is as follows:

[0006] The sleeve pre-embedding device includes a pre-embedding bracket and a sleeve assembly reserved in the wall and connected to the pre-embedding bracket. The pre-embedding bracket includes a first baffle plate, a second baffle plate symmetrically arranged with the first baffle plate, and a connecting pipe fitting for connecting the first baffle plate and the second baffle plate. The sleeve assembly is located between the first baffle plate and the second baffle plate and is arranged circumferentially along the first baffle plate. The sleeve assembly is detachably connected to the first baffle plate and the second baffle plate respectively.

[0007] Furthermore, a first connecting piece is provided between the first baffle plate and the connecting pipe fitting, and a second connecting piece symmetrically arranged with the first connecting piece is provided between the second baffle plate and the connecting pipe fitting. The first baffle plate is connected to the connecting pipe fitting through the first connecting piece, and the second baffle plate is connected to the connecting pipe fitting through the second connecting piece.

[0008] Further, a first round hole for the first connecting member to pass through is provided on the first blocking plate. The first connecting member includes a clamping portion located on the side of the first round hole away from the connecting pipe fitting, and an installation portion connected to the clamping portion and passing through the first round hole. The installation portion is sleeved on the outer side wall of the connecting pipe fitting.

[0009] Further, a limiting portion for preventing the first blocking plate from moving towards the second blocking plate is provided on the side of the installation portion close to the first blocking plate.

[0010] Further, the first blocking plate, the first connecting member, and the connecting pipe fitting are all located on the same central axis.

[0011] Further, the radius of the first blocking plate is R1, the radius of the sleeve assembly is R2, and R1 = R2.

[0012] Further, the connecting pipe fitting is of a hollow structure. A second round hole corresponding to the first round hole is provided on the second blocking plate. The second round hole communicates with the first round hole through the connecting pipe fitting.

[0013] Further, the sleeve assembly is made of one of high-hardness plastic material or metal material.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. For the sleeve pre-embedding device of the present utility model, the first blocking plate and the second blocking plate are connected by using the connecting pipe fitting. The sleeve assembly is circumferentially arranged along the outer edges of the first blocking plate and the second blocking plate to form a cylinder. The sleeve assembly and the pre-embedded support are placed into the beam steel bars. Positioning holes are drilled on both sides of the formwork. Then, the beam steel bars provided with the sleeve assembly and the pre-embedded support are sunk between the formworks. A beam steel bar passes through the positioning holes on both sides of the formwork and the connecting pipe fitting, so that the pre-embedded support and the sleeve assembly are fixed in the beam steel bars. Concrete is poured into the middle of the formwork to form a wall. Finally, the formwork is disassembled, and the pre-embedded support is taken back for continued use next time. The sleeve assembly remains in the wall for pipelines to pass through, effectively solving the problems in the existing sleeve pre-embedding process, where installers bend and weld the beam steel bars near the sleeve towards the sleeve direction according to rough memory for fixation, resulting in large measurement and positioning errors, not only damaging the beam stirrups and causing the beam steel bars to be displaced, but also causing inconsistent sleeve elevations, not being in a straight line, the pipeline being unable to pass through, and the pipeline not being centered.

[0016] 2. By using the first template and the second template on the standard floor to open positioning holes communicating with the connecting pipe fittings, at this time, taking the relative positions of the positioning holes on the first template and the second template and the embedded bracket as the standard. When the concrete is formed, users can remove the first template, the second template and the embedded bracket simultaneously for the next use, without re-measuring and positioning the relative positions between the embedded bracket and the first template and the second template respectively, effectively saving time and labor. At the same time, the construction progress of the embedded project is greatly improved;

[0017] 3. By setting the embedded bracket to cooperate with the first template and the second template respectively, the first template and the second template are demolded synchronously during the form turnover, and are recycled together with the embedded bracket, which is economical and reasonable and will not cause material waste or cost increase.

[0026] The following will make a detailed description of the embodiments of the present utility model in conjunction with the drawings.

[0027] Such as Figures 1 to 7The sleeve embedding device shown includes an embedding support 1 and a sleeve assembly 2 reserved in the wall and connected to the embedding support 1. The embedding support 1 includes a first blocking plate 11, a second blocking plate 12 symmetrically arranged with the first blocking plate 11, and a connecting pipe fitting 13 for connecting the first blocking plate 11 and the second blocking plate 12. The sleeve assembly 2 is located between the first blocking plate 11 and the second blocking plate 12 and is arranged circumferentially along the first blocking plate 11. The sleeve assembly 2 is detachably connected to the first blocking plate 11 and the second blocking plate 12 respectively;

[0028] For the sleeve embedding device of the present utility model, the first blocking plate and the second blocking plate are connected by using a connecting pipe fitting, and the sleeve assembly is arranged circumferentially along the outer edges of the first blocking plate and the second blocking plate to form a cylinder. The sleeve assembly and the embedding support are placed into the beam steel bars. Positioning holes are opened on both sides of the formwork, and then the beam steel bars provided with the sleeve assembly and the embedding support are sunk between the formworks. A beam steel bar is passed through the positioning holes on both sides of the formwork and the connecting pipe fitting so that the embedding support and the sleeve assembly are fixed in the beam steel bars. Concrete is poured into the middle of the formwork to form a wall. Finally, the formwork is disassembled, and the embedding support is retrieved for continued use next time. The sleeve assembly remains in the wall for the pipeline to pass through, effectively solving the problems in the existing sleeve embedding process that during installation construction, the installation workers bend and weld the beam steel bars near the sleeve towards the sleeve direction based on rough memory for fixation, resulting in large measurement and positioning errors, not only damaging the beam stirrups and causing the beam steel bars to be displaced, but also causing inconsistent sleeve elevations, not being in a straight line, the pipeline being unable to pass through, and the pipeline not being centered.

[0029] Optionally, in some embodiments, the connecting pipe fitting 13 is made of a metal material.

[0030] Preferably, the connecting pipe fitting 13 is made of a plastic material.

[0031] Specifically, the connecting pipe fitting 13 is a PVC pipe.

[0032] Optionally, in some embodiments, both the first blocking plate 11 and the second blocking plate 12 are made of a high-hardness plastic material.

[0033] Preferably, both the first blocking plate 11 and the second blocking plate 12 are made of a metal material.

[0034] Specifically, both the first blocking plate 11 and the second blocking plate 12 are made of steel.

[0035] Furthermore, before the embedding construction, the specifications of all commonly used pipelines are counted, and steel blocking plates not larger than the inner diameter of the pipelines used are customized as needed, effectively ensuring that the sizes of the steel blocking plates used in the embedding construction are exactly matched with the pipeline specifications used, avoiding the problem of difficult installation caused by inappropriate blocking plate specifications, and being beneficial to improving the construction efficiency and assembly accuracy.

[0036] Furthermore, the joints between the first baffle 11 and the casing assembly 2 and between the second baffle 12 and the casing assembly 2 need to be wrapped and sealed with adhesive tape to prevent slurry leakage, effectively protecting all components of the embedded bracket and facilitating the extension of the service life of the device.

[0037] Optionally, in some embodiments, the embedded bracket 1 and the casing assembly 2 can be connected by means such as snap connection, lock connection, magnetic attraction connection, and threaded connection.

[0038] Preferably, the connection between the embedded bracket 1 and the casing assembly 2 can be strengthened by wrapping with adhesive tape.

[0039] As Figures 1 to 7 shown, a first connecting piece 3 is provided between the first baffle 11 and the connecting pipe fitting 13, and a second connecting piece 4 symmetrically arranged with the first connecting piece 3 is provided between the second baffle 12 and the connecting pipe fitting 13. The first baffle 11 is connected to the connecting pipe fitting 13 through the first connecting piece 3, and the second baffle 12 is connected to the connecting pipe fitting 13 through the second connecting piece 4;

[0040] Furthermore, by utilizing the first connecting piece 3 and the second connecting piece 4, one end of the connecting pipe fitting 13 is connected to the first baffle 11, and the other end of the connecting pipe fitting 13 is connected to the second baffle 12, which is beneficial to making the connection between the connecting pipe fitting 13 and the first baffle 11 and the second baffle 12 more firm.

[0041] Furthermore, by symmetrically arranging the first connecting piece 3 and the second connecting piece 4, the connection between the connecting pipe fitting 13 and the first baffle 11 and the second baffle 12 can be made more balanced and stable, which is beneficial to improving the quality and safety of the embedded construction and ensuring the stability and reliability between the connecting components.

[0042] Optionally, in some embodiments, the connection method between the first baffle 11 and the connecting pipe fitting 13 and the connection method between the second baffle 12 and the connecting pipe fitting 13 can adopt connection methods such as threaded connection, snap connection, and lock connection.

[0043] Preferably, both the first connecting piece 3 and the second connecting piece 4 are JDG iron cup combs. The JDG iron cup combs have excellent corrosion resistance and tensile strength, which can ensure the stability and reliability of the connection; secondly, the JDG iron cup combs are made of high-quality materials, have a long service life, can reduce the frequency of maintenance and replacement, and lower the maintenance cost; finally, the JDG iron cup combs have a reasonable design structure, have high installation convenience, can improve the construction efficiency and reduce the construction risk.

[0044] Furthermore, the connection between the JDG iron cup comb and the connecting pipe fitting 13 is reinforced by winding with tape. The tape has good sealing and waterproof properties, which can effectively prevent water vapor and corrosive substances from invading the connection part, improving the sealing and corrosion resistance of the connection. Secondly, the tape has good tensile strength and load-bearing capacity, which can enhance the stability and reliability of the connection and avoid the loosening or falling off of the connecting parts. Finally, the tape is simple to use and easy to install, reducing the construction cost and time and improving the construction efficiency.

[0045] As Figures 1 to 7 shown, the first plug plate 11 is provided with a first round hole 111 for the first connecting piece 3 to pass through. The first connecting piece 3 includes a clamping part 31 located on the side of the first round hole 111 away from the connecting pipe fitting 13 and an installation part 32 connected to the clamping part 31 and passing through the first round hole 111. The installation part 32 is sleeved on the outer side wall of the connecting pipe fitting 13.

[0046] Furthermore, the installation part 32 is perpendicularly connected to the clamping part 31, and the cross-section of the first connecting piece 3 is in a "T" shape.

[0047] Furthermore, the clamping part 31 is located on the side of the first plug plate 11 away from the connecting pipe fitting 13 to prevent the first plug plate 11 from moving away from the connecting pipe fitting 13.

[0048] Furthermore, the first plug plate 11 and one end of the connecting pipe fitting 13 are connected by the first connecting piece 3, effectively ensuring the tight connection between the first plug plate 11 and the connecting pipe fitting 13 and enhancing the stability and reliability of the connection.

[0049] Optionally, the size of the first round hole 111 is DN20.

[0050] As Figures 1 to 7 shown, a limiting part 321 for preventing the first plug plate 11 from moving towards the second plug plate 12 is provided on the side of the installation part 32 close to the first plug plate 11.

[0051] Furthermore, the limiting part 321 is located on the side of the first plug plate 11 close to the connecting pipe fitting 13, which can ensure that the first plug plate 11 will not move towards the second plug plate 12 during the installation process, thus ensuring that the positions of the first plug plate 11 and the connecting pipe fitting 13 are stable and correct. The limiting part 321 can effectively prevent the accidental deviation or movement of the first plug plate 11 and ensure the reliability and stability of the connection.

[0052] Optionally, the limiting part 321 can be in the form of a protrusion, a groove, a pin, a thread, etc.

[0053] Optionally, in some other embodiments, the installation part 32 is welded to the side of the first baffle 11 close to the connecting pipe fitting 13 to form a limiting part 321.

[0054] Similarly, the arrangement of the second baffle 12 and the second connecting part 4 is the same as that of the first baffle 11 and the first connecting part 3.

[0055] As Figures 1 to 7 shown, the first baffle 11, the first connecting part 3, and the connecting pipe fitting 13 are all located on the same central axis;

[0056] Furthermore, the arrangement of the first baffle 11, the first connecting part 3, and the connecting pipe fitting 13 on the same central axis makes it easier to align the first baffle 11 and the connecting pipe fitting 13, ensuring their correct positions, and reducing possible offsets and instabilities.

[0057] Similarly, the second baffle 12, the second connecting part 4, and the connecting pipe fitting 13 are also on the same central axis.

[0058] As Figures 1 to 7 shown, the radius of the first baffle 11 is R1, and the radius of the sleeve assembly 2 is R2, and R1 = R2;

[0059] Furthermore, the setting of R1 = R2 effectively ensures that the radii of the sleeve assembly 2 and the first baffle 11 are the same, so that they fit and seal more closely when connected, effectively improving the connection stability and sealing performance.

[0060] Furthermore, the setting of the same radius helps to simplify the installation process of the embedded pipe fittings, reduces the complexity of adjusting the embedded pipe fittings and the sleeve assembly 2, and effectively improves the installation efficiency.

[0061] As Figures 1 to 7 shown, the connecting pipe fitting 13 is a hollow structure, and the second baffle 12 is provided with a second round hole 121 corresponding to the first round hole 111, and the second round hole 121 communicates with the first round hole 111 through the connecting pipe fitting 13;

[0062] Specifically, by setting both the first round hole 111 and the second round hole 121 to communicate with the connecting pipe fitting, during the subsequent construction process of the embedded pipe fittings, the installation constructor locates and drills holes on the template according to the location where the pipe fittings need to be embedded, and then uses a beam steel bar to penetrate through the first round hole 111, the connecting pipe fitting 13, the second round hole 121, and the positioning holes on both sides of the template at the same time, so as to achieve the effect of fixing the embedded bracket, accurately positioning the relative position between the embedded bracket 1 and the template, so that the sleeve assembly 2 is located in the correct position, providing a foundation for the correct installation of the pipeline.

[0063] As Figures 1 to 7The described sleeve assembly 2 is made of either high-hardness plastic material or metal material;

[0064] Optionally, in some embodiments, the sleeve assembly 2 is made of high-hardness plastic material.

[0065] Optionally, in some other embodiments, the sleeve assembly 2 is made of metal material.

[0066] Preferably, the sleeve assembly 2 is made of steel material.

[0067] Furthermore, the steel material has high tensile strength and compressive strength, can withstand greater external loads, and ensures the stability and reliability of the device; secondly, the steel material usually has good wear and corrosion resistance, can be used for a long time in harsh environments without being easily corroded or worn; then, the steel material can be processed by processes such as cold bending and heat treatment, can meet the requirements of different shapes and sizes, and is suitable for various complex environments and engineering needs; finally, the steel material has high stability, is not easily affected by external deformation or vibration, and ensures the stability and safety of the sleeve assembly during use.

[0068] As Figures 1 to 7 The installation method of the sleeve embedding device shown includes a template assembly 5 for injecting concrete to form, several beam steel bars 6, and the sleeve embedding device as described above. The template assembly 5 includes a first template 51 and a second template 52. Each beam steel bar 6 is located between the first template 51 and the second template 52 and intersects vertically and horizontally to form an opening 53. The embedding bracket 1 and the sleeve assembly 2 are passed through the opening 53;

[0069] Furthermore, by using the first template 51 and the second template 52 on the standard floor to open positioning holes communicating with the connecting pipe fitting 13, at this time, the relative positions of the positioning holes on the first template 51 and the second template 52 and the embedding bracket 1 form a standard for use. When the concrete is formed, the user can simultaneously remove the first template 51, the second template 52, and the embedding bracket 1 for next use, without having to re-measure and position the relative positions between the embedding bracket 1 and the first template 51 and the second template 52 respectively, effectively saving time and labor. At the same time, the construction progress of the embedding project is greatly improved;

[0070] Furthermore, by setting the embedding bracket 1 to cooperate with the first template 51 and the second template 52 respectively, the first template 51 and the second template 52 are demolded synchronously when the formwork is turned over, and are recycled together with the embedding bracket 1, which is economical and reasonable, and will not cause material waste or cost increase.

[0071] Preferably, both the first template 51 and the second template 52 are made of aluminum alloy material.

[0072] As Figures 1 to 7The installation method of the sleeve embedded device shown includes the following steps:

[0073] S1: Set the first template 51 and the second template 52 respectively, and open positioning holes communicating with the connecting pipe fitting 13 on the first template 51 and the second template 52;

[0074] S2: Connect a number of beam steel bars 6 vertically and horizontally to form a beam steel bar support module, and an opening 53 for the embedded support 1 and the sleeve assembly 2 to pass through is provided on the beam steel bar support module;

[0075] S3: Connect and encapsulate the embedded support 1 and the sleeve assembly 2 to form an embedded device, and pass the embedded device through the opening 53;

[0076] S4: Place the beam steel bar support module with the embedded device between the first template 51 and the second template 52;

[0077] S5: Use a beam steel bar 6 to sequentially penetrate the positioning hole on the first template 51, the connecting pipe fitting 13, and the positioning hole on the second template 52, and inject concrete between the first template 51 and the second template 52;

[0078] S6: After the concrete solidifies to form a wall, remove the first template 51 and the second template 52. The embedded support 1 and the sleeve assembly 2 are detachably connected. Take out the embedded support 1 for continued use next time, and the sleeve assembly 2 remains in the wall for the pipe fitting to pass through.

[0079] In step S1, the first template 51 and the second template 52 enclose a pouring space for injecting concrete. At this time, the installation constructor determines the relative positions of the first template 51 and the second template 52 with respect to the connecting pipe fitting 13 according to the position and direction of the pipe fitting to be installed as required, so as to determine the positions of the positioning holes on the first template 51 and the second template 52 that communicate with the connecting pipe fitting 13 respectively. The positions of the positioning holes on the first template 51 and the positions of the positioning holes on the second template 52 coincide with the positions of the centers of the two ends of the central axis of the pipe fitting to be installed respectively.

[0080] Further, in the prior art, the installation constructor first confirms the positions of the first template 51 and the second template 52, then combines a number of beam steel bars 6 into a beam steel bar support module, and then places the embedded device into the beam steel bar support module according to the rough memory of the installation constructor. Here, the rough memory means that the installation constructor believes that the position of the embedded device in the beam steel bar support module is the position of the pipe fitting to be installed based on personal feeling. This approach has certain errors, which may lead to problems such as the position of the embedded device in the beam steel bar support module not matching the position of the subsequent pipe fitting to be installed, not being on a straight line, the pipe fitting to be installed being unable to pass through, or the pipe fitting to be installed not being centered. Through step S1, it can be confirmed that the centers of the two ends of the central axis of the subsequent pipe fitting to be installed coincide with the positions of the positioning holes on the first template 51 and the positioning holes on the second template 52 respectively.

[0081] In step S2, first, several beam steel bars 6 are connected in a crisscross pattern as required to form a beam steel bar support module. It is necessary to ensure that the crisscross connection between the beam steel bars 6 is firm enough to effectively bear the expected load and pressure. Then, openings 53 for the embedded devices to pass through are set on the beam steel bar support module. The openings 53 need to be determined according to the sizes of the sleeve assembly 2 and the embedded bracket 1 to ensure that the openings 53 can accommodate the installation of the sleeve assembly 2 and the embedded bracket 1 and remain stable. Finally, the construction workers conduct quality inspection and testing on the beam steel bar support module to ensure that the quality and stability of the beam steel bar support module meet the relevant requirements.

[0082] In step S3, the sleeve assembly 2 and the embedded bracket 1 of the same specification as the subsequent installed pipe fittings need to be connected to form an embedded device. Optionally, in some embodiments, the connection methods between the sleeve assembly 2 and the embedded bracket 1 can be threaded connection, snap connection, magnetic attraction connection, etc. Further, as a preferred but non-limiting manner of the present invention, the connection part between the sleeve assembly 2 and the embedded bracket 1 is reinforced and encapsulated by winding with adhesive tape. Winding with adhesive tape can effectively seal the connection part to prevent the concrete slurry from seeping into the interior of the embedded device and affecting the use effect of the embedded device. When winding with adhesive tape, it is necessary to ensure the tightness and integrity of the adhesive tape winding to ensure the encapsulation effect. At the same time, attention also needs to be paid to the continuity and coverage area of the winding to ensure that the connection part is fully wrapped and fixed to prevent slurry leakage and damage. In addition, adhesive tape of a suitable material needs to be selected to ensure that the adhesive tape has good sealing performance and durability to ensure the sealing of the connection part between the sleeve assembly 2 and the embedded bracket 1. Finally, the encapsulated embedded device is passed through the preset opening 53 on the beam steel bar support module.

[0083] In step S4, it should be noted that the embedded device needs to be placed before the beam steel bar support module sinks into the pouring space.

[0084] In step S5, by using a beam steel bar 6 to sequentially pass through the positioning holes on the first formwork 51, the connecting pipe fitting 13, and the positioning holes on the second formwork 52, it is effectively ensured that the centers of the two ends of the central axis of the subsequent installed pipe fitting coincide with the positions of the positioning holes on the first formwork 51 and the positioning holes on the second formwork 52, ensuring that the position of the embedded device in the beam steel bar support module is accurate and error-free. Therefore, the position of the subsequent installed pipe fitting is effectively ensured to be accurate and error-free. At the same time, under the action of the beam steel bars, the embedded device can be fixed in the beam steel bar support module to prevent the embedded device from moving during the concrete pouring process. Secondly, when injecting concrete into the pouring space, attention should be paid to the pouring sequence and method of the concrete to ensure that the internal voids of the beam steel bar support module can be filled, and the generation of bubbles and voids should be minimized.

[0085] Furthermore, in the prior art, in order to fix the position of the embedded device in the beam steel bar support module, installation constructors usually pry or knock the beam steel bars 6 near the embedded device destructively so that the beam steel bars 6 can bend and extend towards the embedded device, and then fixedly connect the beam steel bars 6 and the embedded device by welding to prevent the embedded device from moving during the concrete pouring process. This practice causes the overall structure of the beam steel bar support module to be displaced and is likely to damage the overall structure of the beam steel bar support module, posing a safety hazard. Through step S5, the problem that installation constructors pry or knock the beam steel bars 6 destructively to fix the position of the embedded device in the beam steel bar support module is effectively solved, which is beneficial to protecting the overall structure of the beam steel bar support module and preventing the overall structure of the beam steel bar support module from being damaged.

[0086] In step S6, before removing the first formwork 51 and the second formwork 52, it is necessary to ensure that the concrete in the pouring space has completely solidified to avoid damage to the wall structure; secondly, during the process of removing the first formwork 51 and the second formwork 52, special formwork removal tools can be used to ensure that the wall surface remains intact and flat; then, remove the adhesive tape at the connection between the sleeve assembly 2 and the embedded support 1 so that the embedded support 1 can be disassembled for subsequent reuse, and the sleeve assembly 2 remains in the wall for the threading of subsequent installation pipe fittings; finally, conduct a quality inspection on the wall, and if necessary, perform repair and finishing work.

[0087] Furthermore, in step S6, it should be noted that the first formwork 51 and the second formwork 52 cannot be rotated or replaced during the formwork removal process to prevent the loss of positioning holes. During the above operation process, the embedded support 1 forms relative position standards with the positioning holes on the first formwork 51 and the second formwork 52 respectively. When the user needs to lay installation pipe fittings of the same type and specification, only the embedded support 1, the first formwork 51 and the second formwork 52 of this time can be used to confirm the relative positions of the subsequent installation pipe fittings, without re-measuring the relative positions of the subsequent installation pipe fittings with the first formwork 51 and the second formwork 52 in the beam steel bar support module respectively, effectively saving time and labor costs and greatly improving the construction progress of the embedded project; secondly, the recycling of the embedded support 1, the first formwork 51 and the second formwork 52 is economical, reasonable and efficient, which is beneficial to saving resources and preventing resource waste.

[0088] Processing steps of the embedded device:

[0089] Before the construction of embedded pipe fittings, count all common casing specifications, customize steel blanking plates no larger than the inner diameter of the casings used as required, and reserve a DN20 hole in the middle of the blanking plates for installing iron cup combs. Then, cut PVC connecting pipes of the same length according to the actual length of the embedded pipe fittings, connect both ends of the PVC connecting pipes to the iron cup combs, and wrap adhesive tape around the connection between the PVC connecting pipes and the iron cup combs for reinforcement. At this time, the two blanking plates are connected through the iron cup combs and the PVC connecting pipes to form an embedded support 1, and then the embedded support 1 is installed on the casing assembly 2. The connection between the embedded support 1 and the casing assembly 2 is wrapped with adhesive tape again for sealing to form an embedded device.

[0090] Usage steps of the embedded device:

[0091] Set the first template 51 and the second template 52, and position and drill holes on the first template 51 and the second template 52 according to the position where the pipeline needs to be installed. Connect several beam steel bars 6 vertically and horizontally to form a beam steel bar support module. An opening 53 for placing the embedded device is provided on the beam steel bar support module, and the embedded device is placed into the beam steel bar support module by using the opening 53. Then, the beam steel bar support module with the embedded device is sunk between the first module 51 and the second module 52. Then, use a beam steel bar 6 to sequentially penetrate the positioning holes on the first template 51, the connecting pipe fitting 13, and the positioning holes on the second template 52 to fix the correct position of the embedded device. Then, pour concrete between the first template 51 and the second template 52. After the concrete solidifies, a wall is formed. Finally, the first template 51, the second template 52, and the embedded support 1 are removed simultaneously for continued use next time, and the casing assembly 2 remains in the wall for the pipeline to pass through.

[0092] It should be noted that:

[0093] 1. After the first template 51 and the second template 52 are removed, when continuing to use, the directions of the first template 51 and the second template 52 cannot be reversed, or the templates cannot be replaced to prevent the loss of positioning holes.

[0094] 2. The embedded support 1 and the casing assembly 2 need to be set on the beam steel bar support module first, and then the beam steel bar support module is sunk between the first template 51 and the second template 52.

[0095] 3. The connection between the embedded support 1 and the casing assembly 2 needs to be sealed to prevent slurry from flowing into the device.

[0096] 4. After the concrete is formed, remove the formwork in time to prevent the loss of the mold.

[0097] The implementation mode of this embodiment is as follows:

[0098] The sleeve pre-embedding device includes a pre-embedding support 1 and a sleeve assembly 2 reserved in the wall and connected to the pre-embedding support 1. The pre-embedding support 1 includes a first blocking plate 11, a second blocking plate 12 symmetrically arranged with the first blocking plate 11, and a connecting pipe fitting 13 for connecting the first blocking plate 11 and the second blocking plate 12. The sleeve assembly 2 is located between the first blocking plate 11 and the second blocking plate 12 and is circumferentially arranged along the outer edges of the first blocking plate 11 and the second blocking plate 12. A first round hole 111 is provided on the first blocking plate 11, a second round hole 121 is provided on the second blocking plate 12, and the connecting pipe fitting 13 is of a hollow structure. The connecting pipe fitting 13, the first round hole 111, and the second round hole 121 are communicated. When the sleeve assembly 2 and the pre-embedding support 1 are placed into the beam steel bars 6, positioning holes are drilled on both sides of the formwork according to the position where the pipeline needs to be installed. Then, the beam steel bars 6 provided with the sleeve assembly 2 and the pre-embedding support 1 are sunk between the formworks, and a beam steel bar 6 is passed through the positioning holes on both sides of the formwork and the connecting pipe fitting 13, so that the pre-embedding support 1 and the sleeve assembly 2 are fixed in the beam steel bars. Concrete is poured into the middle of the formwork to form a wall. Finally, the formwork is disassembled, and the pre-embedding support 1 is retrieved for continued use next time. The sleeve assembly 2 remains in the wall for the pipeline to pass through, effectively solving the problems in the existing sleeve pre-embedding process. During installation and construction, the installation workers bend and weld the beam steel bars near the sleeve towards the sleeve direction according to rough memory for fixation, resulting in large measurement and positioning errors. This not only damages the beam stirrups and causes the beam steel bars to be displaced, but also leads to inconsistent sleeve elevations, not being in a straight line, the pipeline being unable to pass through, and the pipeline not being centered.

[0099] The installation method of the sleeve pre-embedding device includes a formwork assembly 5 for injecting concrete to form, several beam steel bars 6, and the sleeve pre-embedding device as described above. The formwork assembly 5 includes a first formwork 51 and a second formwork 52. The installation workers drill positioning holes on the first formwork 51 and the second formwork 52 according to the position where the pipeline needs to be installed. The several beam steel bars 6 are connected vertically and horizontally to form a beam steel bar support module. An opening 53 for placing the pre-embedding device is provided on the beam steel bar support module, and the pre-embedding device is placed into the beam steel bar support module using the opening 53. Then, the beam steel bar support module provided with the pre-embedding device is sunk between the first module 51 and the second module 52. Next, a beam steel bar 6 is passed through the positioning hole on the first formwork 51, the connecting pipe fitting 13, and the positioning hole on the second formwork 52 in sequence to fix the correct position of the pre-embedding device. Then, concrete is injected between the first formwork 51 and the second formwork 52. After the concrete solidifies, a wall is formed. Finally, the first formwork 51, the second formwork 52, and the pre-embedding support 1 are simultaneously removed for continued recycling use next time. The sleeve assembly 2 remains in the wall for the pipeline to pass through.

Any technical extension or re-creation made according to the present utility model is protected by the present utility model. The protection scope of the present utility model shall be subject to the claims.
