Description

Technical Field

[0001] The invention belongs to the technical field of construction, and in particular relates to a steel bar deviation correction and introduction device for assembly and an installation method thereof. Background Art

[0002] When the prefabricated components are hoisted at the construction site, the protruding steel bars of the lower prefabricated components need to be aligned and inserted into the sleeves of the upper prefabricated components. Due to the errors in the production process of the lower prefabricated components, the protruding steel bars are easily displaced by external forces during storage and transportation. When the lower prefabricated components are provided with multiple protruding steel bars, the corresponding protruding steel bars and the embedded sleeves of the upper prefabricated components are misaligned, which brings great difficulties to the installation of the prefabricated components. It is necessary to adjust the position of the protruding steel bars on site to correct the position deviation of the protruding steel bars so that they are aligned with the upper prefabricated sleeves.

[0003] The method used in the prior art is: 1. Correct the steel bars first, and adjust the offset steel bars to the designed position as much as possible; 2. During the trial hoisting, the construction personnel observe the corresponding positions of the protruding steel bars of the lower prefabricated component and the sleeve cavity of the upper prefabricated component. Since the assembly position is located at the bottom of the component, the observer needs to lie down to observe the alignment of the protruding steel bars and the sleeve cavity, or use a mirror to observe the alignment of the protruding steel bars and the sleeve cavity one by one; 3. When it is observed that the steel bar deviation exceeds the range and the upper component cannot be installed in place, it is necessary to record the observation. And according to the recorded situation; 4. Remove the upper prefabricated component, make a steel bar deviation adjustment plan according to the recorded situation, and adjust the steel bars; 5. Formal hoisting. Repeat step 3, and continuously adjust the position of the upper component until all steel bars are observed to be aligned with the sleeve cavity, and slowly lower the upper prefabricated component.

[0004] According to the requirements of prefabricated component manufacturing and hoisting, the maximum allowable deviation of the axial position of the corresponding protruding steel bar and the sleeve is relatively small, generally within the range of 5mm--10mm. When there are multiple protruding steel bars, the cumulative effect of errors makes hoisting more difficult, and often requires multiple "hoisting-observation-adjustment of protruding steel bars-hoisting again" cycles of construction, which is time-consuming, labor-intensive and inefficient. In particular, when checking the number of steel bars, the steel bar offset adjustment plan formulated after observing the relative position of the steel bars and the sleeve cavity is often based on intuition and has limitations, so that the subsequent hoisting still fails to smoothly put the upper prefabricated components into place due to the misalignment of steel bars in other positions.

[0005] In summary, there is an urgent need to provide a steel bar deviation correction and introduction device for assembly that is simple in structure, convenient, fast, and reusable, and an installation method thereof. Summary of the invention

[0006] The technical problem to be solved by the present invention is: to provide a steel bar correction introduction device which is simple in structure, convenient, fast and reusable, so as to solve the technical problems existing in the prior art such as the lack of efficient auxiliary tools for steel bar correction and the complicated and inefficient steel bar correction process; the present invention also provides an installation method for the steel bar correction introduction device, so as to improve the steel bar correction construction efficiency at the construction site and reduce the operation intensity of the construction personnel.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A steel bar correction and introduction device for assembly, the steel bar correction and introduction device is composed of at least two inner cones spliced ​​together, each of the inner cones is spliced ​​to form a cylindrical structure with an internal cavity as a truncated cone, and the outer periphery of the inner cone is also provided with fasteners connecting the inner cones together.

[0009] In another preferred embodiment, the inner cone includes a cone body and a cone mouth connected together, and the connection between the cone mouth and the cone body is a smooth arc surface; wherein the end of the inner cone with a larger diameter is the cone mouth, and the other end is the cone body.

[0010] In another preferred embodiment, it further comprises a magnetic ring sleeved on the outer circumference of the cone body, wherein the magnetic ring comprises two separable half rings.

[0011] In another preferred embodiment, the magnetic ring is arranged on the outer periphery of the connection between the cone body and the cone mouth.

[0012] In another preferred embodiment, a groove is further provided on the outer periphery of the connection between the cone body and the cone mouth. After the inner cones are assembled, the grooves on the cone bodies are interconnected to form an annular cone shoulder; the magnetic ring is arranged at the cone shoulder.

[0013] In another preferred embodiment, the opening direction of the groove faces the cone mouth, and the height of the magnetic ring is lower than the height of the cone shoulder.

[0014] In another preferred embodiment, the fastener comprises an open clamp connecting the inner cones together, and a buckle for adjusting the diameter of the open clamp is provided at the end of the open clamp.

[0015] In another preferred embodiment, the opening clamp is arranged on an end of the cone body away from the cone mouth.

[0016] In another preferred embodiment, the inclination of the truncated cone formed inside each of the inner cones after being assembled does not exceed 1:6, and the inclination is the absolute value of the ratio of the upper and lower radius difference of the truncated cone to the height.

[0017] In another preferred embodiment, the height of the cone nozzle is 20-40 mm.

[0018] In another preferred embodiment, the end of the cone body away from the cone mouth is a cone bottom, and the thickness of the cone bottom is not less than 2-4 mm.

[0019] The present invention also provides a method for installing the above-mentioned steel bar deviation correction introduction device for assembly, comprising the following steps:

[0020] S1. Align the inner cones and clamp them with fasteners to form a cylindrical body with a truncated cone-shaped cavity inside;

[0021] S2, aligning the end of the protruding steel bar to be corrected with the truncated cone-shaped cavity of the inner cone, and moving along the surface of the cavity until the end of the protruding steel bar protrudes from the top side of the truncated cone-shaped cavity;

[0022] S3. Position the end of the extended steel bar to the target position, remove the fasteners, split each inner cone and remove it from the outer periphery of the extended steel bar.

[0023] In another preferred embodiment, when the steel bar correction and introduction device is used to perform the construction operation of introducing the protruding steel bars into the sleeve, the step S1 also includes: inserting the end of the inner cone tube with a smaller inner diameter after splicing into the sleeve cavity of the sleeve of the upper prefabricated component and fixing it below the sleeve; the step S2 also includes: the end of the protruding steel bar extends from the top side of the truncated cone-shaped cavity and extends into the sleeve cavity of the sleeve; the step S3 also includes: removing the end of each inner cone tube with a smaller inner diameter from the sleeve, and then splitting each inner cone tube and removing it from the outer periphery of the protruding steel bar.

[0024] The beneficial technical effects achieved by the technical solution of the present invention are:

[0025] 1. The steel bar correction introduction device for assembly of the present invention is composed of at least two inner cones, so that when in use, the inner cones are spliced ​​together, and then the inner cones are connected and fixed by fasteners, forming a truncated cone-shaped cavity with a small top and a large bottom inside, and the end of the protruding steel bar to be corrected is extended into the bottom of the truncated cone-shaped cavity; because the radius of the truncated cone-shaped cavity gradually decreases from bottom to top, in the process of the protruding steel bar slowly being introduced into the truncated cone-shaped cavity and extending from the top of the truncated cone-shaped cavity, the verticality of the protruding steel bar slowly changes, thereby realizing the correction of the protruding steel bar.

[0026] 2. When the steel bar deviation correction introduction device of the present invention is used to align the protruding steel bars of the lower prefabricated component with the sleeve of the upper prefabricated component, the steel bar deviation correction introduction device is first placed at the bottom end of the sleeve of the upper prefabricated component, and then the end of the protruding steel bar of the lower prefabricated component is extended into the bottom side of the steel bar deviation correction introduction device. Under the action of the gravity of the lower prefabricated component, the protruding steel bar is corrected through the inner cone surface of the truncated cone-shaped cavity, and the end of the protruding steel bar is extended from the cone mouth end and placed in the sleeve of the upper prefabricated component. The operation process is simple, reducing the workload of correcting the protruding steel bars during construction and improving construction efficiency.

[0027] 3. The steel bar deviation correction introduction device of the present invention allows the verticality deviation of a single steel bar to be expanded by 200%-300% compared with the deviation range of steel bars in the prior art. The protruding steel bars within this range can be directly corrected and introduced into the sleeve cavity; for the protruding steel bars whose verticality deviation is greater than the original allowable deviation by 200%-300%, they can be corrected by manual adjustment first, and then the steel bar deviation correction introduction device can be used. After the steel bar deviation correction is achieved by the steel bar deviation correction introduction device of this scheme, the fasteners can be removed and the inner cones can be disassembled; they can be reused later to reduce construction costs.

[0028] 4. The installation method of the steel bar deviation correction guide device of the present invention, by expanding the allowable deviation of the steel bar, uses the gravity of the prefabricated component to correct the steel bar during the hoisting process, so that the upper end of the steel bar can be naturally guided into the sleeve cavity of the corresponding sleeve, saving time and labor, and improving the hoisting efficiency. The device is economical and applicable, easy to operate, and can be used in, but not limited to, the assembly construction of prefabricated components such as buildings and bridges.

[0044] The present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention. In addition, those skilled in the art can make corresponding combinations of the features in the embodiments and in different embodiments in this document based on the description of this document.

[0045] Reference Figure 1 and attached Figure 2As shown in the figure, the steel bar correction introduction device 01 for assembly in one embodiment of the present invention is composed of two inner cones 1, each inner cone 1 is formed by splicing together to form a cylindrical structure with an internal cavity 8 as a truncated cone, and the outer periphery of the inner cone 1 is also provided with fasteners for connecting each inner cone 1 together. In this way, when in use, the two inner cones 1 are spliced ​​together, and then the inner cones 1 are connected and fixed by fasteners, and a truncated cone-shaped cavity 8 with a small top and a large bottom is formed inside, and the end of the protruding steel bar 04 to be corrected is extended into the bottom of the truncated cone-shaped cavity 8; because the radius of the truncated cone-shaped cavity 8 is gradually reduced from bottom to top, in the process of the protruding steel bar 04 slowly being introduced into the truncated cone-shaped cavity 8 and extending from the top of the truncated cone-shaped cavity 8, the verticality of the protruding steel bar 04 slowly changes, thereby realizing the correction of the protruding steel bar 04. In other embodiments, three or four inner cones 1 can also be set to be spliced, and each inner cone 1 can be fastened together when in use.

[0046] By using the steel bar deviation correction introduction device 01 in this embodiment, the verticality deviation range allowed for the protruding steel bar 04 when the protruding steel bar 04 is inserted into the sleeve cavity of the corresponding sleeve 05 is increased. Before the steel bar deviation correction introduction device 01 of this embodiment is set, the maximum verticality deviation value allowed when the protruding steel bar 04 is inserted into the sleeve cavity is 5mm; after the steel bar deviation correction introduction device 01 is set, since the interior of the steel bar deviation correction introduction device 01 is a truncated cone-shaped cavity 8 that is small at the top and large at the bottom, the maximum verticality deviation value allowed when the protruding steel bar 04 is extended from the bottom of the steel bar deviation correction introduction device 01 is 14mm. This greatly simplifies the verticality adjustment steps of the protruding steel bar 04 at the construction site, reduces the labor intensity of construction personnel, and improves construction efficiency.

[0047] The following briefly introduces the installation method of the steel bar deviation correction introduction device 01 for assembly in this embodiment, which includes the following steps:

[0048] S1, aligning the inner cones 1 and clamping them with fasteners to form a cylindrical body with a truncated cone-shaped cavity 8 inside;

[0049] S2, aligning the end of the protruding steel bar 04 to be corrected with the truncated cone-shaped cavity 8 of the inner cone 1, and moving along the surface of the cavity 8 until the end of the protruding steel bar 04 protrudes from the top side of the truncated cone-shaped cavity 8;

[0050] S3, the end of the to-be-extended steel bar 04 is positioned at the target position, the fasteners are removed, and each inner cone 1 is split and removed from the outer periphery of the extended steel bar 04.

[0051] In another preferred embodiment, when the steel bar correction and introduction device 01 is used to perform the construction operation of introducing the protruding steel bar 04 into the sleeve 05, step S1 also includes: inserting the end of the inner cone 1 with a smaller inner diameter after splicing into the sleeve cavity of the sleeve 05 of the upper prefabricated component 02; step S2 also includes: the end of the protruding steel bar 04 extends from the top side of the truncated cone-shaped cavity 8 and is placed in the sleeve cavity of the sleeve 05; step S3 also includes: removing the end of the inner cone 1 with a smaller inner diameter from the sleeve 05, and then splitting each inner cone 1 and removing it from the outer periphery of the protruding steel bar 04.

[0052] See attached Figure 4 As shown, the inner cone 1 in this embodiment includes a cone body 2 and a cone mouth 3 connected together, and the connection between the cone mouth 3 and the cone body 2 is a smooth camber; wherein the end of the inner cone 1 with a larger diameter is the cone mouth 3, and the other end is the cone body 2. In this way, after the two inner cones 1 are assembled, the two cone mouths 3 are assembled with each other, and the two cone bodies 2 are assembled with each other, and the cone mouth 3 and the cone body 2 together form a truncated cone-shaped cavity 8. The cavity 8 is small at the top and large at the bottom, and the diameter at the top cone mouth 3 is slightly larger than the diameter of the steel bar to be corrected. The truncated cone-shaped cavity 8 is a space with a gradually decreasing diameter. When the steel bar to be corrected is inserted into the cavity 8 from the bottom of the cavity 8 to pass through the cone mouth 3, the truncated cone-shaped cavity 8 provides a guiding effect on the steel bar, thereby realizing the adjustment of the verticality of the steel bar.

[0053] See attached Figure 1 As described above, based on the above embodiment, in another improved embodiment, the steel bar deviation correction introduction device 01 further includes a magnetic ring 5 sleeved on the outer periphery of the cone body 2, and the magnetic ring 5 includes two separable half rings. In this way, the magnetic ring 5 can be sleeved on the outer periphery of the cone body 2 during use; after use, the magnetic ring 5 can be removed first, and then the inner cone 1 can be separated from each other, which is easy to operate and can be reused.

[0054] See attached Figure 1 As shown, based on the above embodiment, in another improved embodiment, the magnetic ring 5 is arranged on the periphery of the connection between the cone body 2 and the cone mouth 3. This arrangement, on the one hand, ensures the safety of the connection between the cone body 2 and the cone mouth 3, and avoids the separation between the inner cone 1 when correcting the verticality of the steel bar; on the other hand, when the steel bar deviation correction introduction device 01 is used (see attached Figure 7As shown in the figure, the cone nozzle 3 is partially inserted into the sleeve cavity of the sleeve 05 embedded at the bottom side of the upper prefabricated component 02. The magnetic ring 5 is adsorbed on the sleeve 05 by magnetic force, realizing the connection between the steel bar correction introduction device 01 and the sleeve 05. The steel bar correction introduction device 01 can be stably fixed to the bottom side of the sleeve 05 of the upper prefabricated component 02. The protruding steel bar 04 of the lower prefabricated component 03 is then guided into the sleeve 05 by the steel bar correction introduction device 01, thereby realizing the correction of the protruding steel bar 04. In order to facilitate the connection between the cone nozzle 3 and the sleeve 05, according to the specifications of the sleeve 05 to be connected (generally ), the inner diameter of the cone mouth 3 of the steel bar correction introduction device 01 is set to be 2-4mm smaller than the inner diameter of the sleeve 05; the upper outer diameter of the cone mouth 3 is generally 1-2mm smaller than the inner diameter of the sleeve 05, so that the cone mouth 3 can be inserted into the sleeve cavity of the sleeve 05.

[0055] See attached Figure 3 As shown, based on the above embodiment, in another improved embodiment, a groove is further arranged on the outer periphery of the connection between the cone body 2 and the cone mouth 3. After the inner cones 1 are assembled, the grooves on the cone bodies 2 are interconnected to form an annular cone shoulder 4; the magnetic ring 5 is arranged on the cone shoulder 4. Figure 4 As shown, the opening direction of the groove faces the cone mouth 3, and the height of the magnetic ring 5 is lower than the height of the cone shoulder 4. With this arrangement, the closed loop can be stably stuck in the groove and is not easy to fall off; and the upper surface of the magnetic ring 5 is not blocked. When the cone mouth 3 is partially inserted into the sleeve cavity of the sleeve 05 at the bottom side of the upper prefabricated component 02, the upper surface of the magnetic ring 5 is adsorbed with the bottom side of the sleeve 05, thereby achieving the stable fixing of the steel bar correction introduction device 01 to the bottom side of the sleeve 05 of the upper prefabricated component 02, so that the protruding steel bar 04 of the lower prefabricated component 03 passes through the steel bar correction introduction device 01 and is inserted into the sleeve cavity of the sleeve 05.

[0056] See attached Figure 1 and attached Figure 2 As shown, based on the above embodiment, in another improved embodiment, the fastener includes an open clamp 6 that tightly connects the inner cones 1 together, and the end of the open clamp 6 is provided with a buckle for adjusting the diameter of the open clamp 6. The open clamp 6 is arranged on the cone body 2 at one end away from the cone mouth 3. This arrangement ensures that the inner cones 1 will not separate during use, and the bottom side diameter of the truncated cone-shaped cavity 8 of the steel bar correction introduction device 01 can be appropriately adjusted according to the degree of deviation of the steel bar to be corrected.

[0057] See attached Figure 1As shown, based on the above embodiment, in another improved embodiment, the inclination of the truncated cone formed inside each inner cone 1 after being assembled does not exceed 1:6, and the inclination is the absolute value of the ratio of the upper and lower radius difference of the truncated cone to the height. In this way, it can ensure that the steel bar correction introduction device 01 provides a guiding function for the steel bar to be corrected, and at the same time, it can ensure that the height between the upper and lower prefabricated components 03 is greater than the height of the steel bar correction introduction device 01, so as to facilitate the disassembly of the steel bar correction introduction device 01.

[0058] See attached Figure 1 and attached Figure 3 As shown, based on the above embodiment, in another improved embodiment, the height of the cone mouth 3 is 20-40 mm. In this way, the cone mouth 3 can be partially inserted into the sleeve cavity of the sleeve 05, which is convenient for introducing the steel bar to be corrected into the sleeve cavity and convenient for disassembly.

[0059] See attached Figure 1 and attached Figure 3 As shown, based on the above embodiment, in another improved embodiment, the end of the cone body 2 away from the cone mouth 3 is a cone bottom 9, and the thickness of the cone bottom 9 is not less than 2-4mm. Since the cone body 2 is the thinnest part of the steel bar deviation correction introduction device 01, if the thickness is too small, cracks are likely to appear during use. Setting the thickness of the cone bottom 9 to 2-4mm can resist the lateral reaction force of the steel bar deformation and avoid damage.

[0060] The following is combined with Figure 5 To Attachment Figure 8 , briefly introduce the installation method and working principle of the steel bar deviation correction introduction device 01:

[0061] 1. Install the magnetic ring 5 on the cone shoulder 4;

[0062] 2. Align the two inner cones 1 and clamp them with a clamp to form a cylindrical body with a truncated cone-shaped cavity 8 inside;

[0063] 3. Insert the cone nozzle 3 with a smaller inner diameter into the sleeve cavity of the sleeve 05 embedded in the upper prefabricated component 02, and use the magnetism of the magnetic ring 5 to attract the bottom end of the sleeve 05;

[0064] When the upper prefabricated component 02 is pre-buried with multiple sleeves 05, a steel bar deviation correction introduction device 01 is installed at the bottom of each sleeve 05 according to the above steps;

[0065] 4. Check the protruding steel bars 04 of the lower prefabricated component 03, and perform manual preliminary deviation correction for the protruding steel bars 04 whose vertical deviation obviously exceeds the adjustment range of the steel bar deviation correction introduction device 01;

[0066] 5. Lift the upper prefabricated component 02 and lower it vertically. When the protruding steel bars 04 of the lower prefabricated component 03 are close to the conical bottom 9 of the steel bar deviation correction guide device 01, adjust the upper prefabricated component 02 horizontally so that the protruding steel bars 04 of the lower prefabricated component 03 are aligned with the truncated cone-shaped cavity 8 of the steel bar deviation correction guide device 01 at the bottom of the upper prefabricated component 02 (see the attached drawing). Figure 5 shown);

[0067] 6. Slowly lower the upper prefabricated component 02, and the extended steel bar 04 slowly extends into the truncated cone-shaped cavity 8, until it passes through the cone mouth 3 and then extends into the sleeve cavity of the sleeve 05; when the extended steel bar 04 encounters resistance, the upper prefabricated component 02 is finely adjusted horizontally, and the upper prefabricated component 02 is continuously lowered, and the self-weight of the upper prefabricated component 02 is used to make the deflected extended steel bar 04 deviate along the inner cone surface of the truncated cone-shaped cavity 8, thereby achieving the effect of correcting the deviation of the extended steel bar 04 (see attached Figure 6 and attached Figure 8 shown);

[0068] 7. Continue to lower the upper prefabricated component 02 until all the protruding steel bars 04 pass through the steel bar deviation correction introduction device 01 and extend into a certain position in the sleeve 05. At this time, at least ensure that the height between the upper and lower prefabricated components 03 is greater than the height of the steel bar deviation correction introduction device 01, so as to leave enough operating space for disassembling the steel bar deviation correction introduction device 01;

[0069] 8. Use a tool to remove the steel bar deviation correction guide device 01 from the sleeve cavity;

[0070] 9. Open the buckle of the open clamp 6 and take out the open clamp 6; since the clamp is open, the protruding steel bar 04 does not affect the removal of the clamp (see attached Figure 7 shown);

[0071] 10. Take out the magnetic ring 5. Since the magnetic ring 5 is formed by two half magnetic rings 5 ​​being attracted together, the protruding steel bar 04 in the middle does not affect the taking out of the half magnetic ring 5. Separate the two half magnetic rings 5 ​​from the bottom of the sleeve 05 or the shoulder 4 of the cone body 2, and take out the magnetic ring 5 with force.

[0072] 11. Separate the two inner cones 1 and remove them from around the protruding steel bars 04;

[0073] 12. Continue to lower the upper prefabricated component 02 to the predetermined position. At this time, all the protruding steel bars 04 enter the sleeve cavity of the sleeve 05 of the upper prefabricated component 02, completing the construction steps of hoisting the protruding steel bars 04 into place.

[0074] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
