Description

TECHNICAL FIELD

[0001] The present application relates to a prefabricated component auxiliary installation device and method, in particular to a prefabricated component cantilever reinforcement in-place auxiliary device and method. BACKGROUND

[0002] In recent years, fabricated buildings have been applied more and more widely in the field of building construction due to their advantages of green environmental protection and high efficiency, and have gradually replaced the traditional building construction mode. The fabricated building construction mainly includes the assembly of prefabricated components such as prefabricated PC wall panels and prefabricated PC columns, and the vertical assembly of prefabricated components is more difficult.

[0003] Taking prefabricated PC wall panels as an example, when prefabricated PC wall panels are vertically assembled, the grouting sleeve at the bottom of the upper prefabricated PC wall panel needs to be matched and inserted with the cantilever reinforcement at the top of the lower prefabricated PC wall panel after the lower prefabricated PC wall panel is installed. However, in the actual construction process, the cantilever reinforcement of the prefabricated PC wall panel may be deviated due to various factors such as processing errors and on-site construction collisions, so that the cantilever reinforcement of the next prefabricated PC wall panel cannot be smoothly inserted into the grouting sleeve of the upper prefabricated PC wall panel. The construction personnel need to correct the cantilever reinforcement one by one before hoisting the upper prefabricated PC wall panel, which reduces the assembly efficiency of the prefabricated PC wall panel and cannot guarantee the construction quality. Therefore, it is necessary to provide a prefabricated component cantilever reinforcement in-place auxiliary device and method which can correct the cantilever reinforcement and assist the installation of prefabricated components.

[0040] When the precast component 5 is processed, two rows of cantilever reinforcements 6 arranged alternately are extended from the top of the precast component 5, which are used for vertically aligning and connecting the precast components 5. A plurality of sets of positioning assemblies 3 and jacking assemblies 4 are installed on the pair of wrench rods 1, the number and interval of the positioning assemblies 3 on one of the wrench rods 1 correspond to one row of cantilever reinforcements 6 on one side of the precast component 5, the number and interval of the positioning assemblies 3 on the other wrench rod 1 correspond to one row of cantilever reinforcements 6 on the other side of the precast component 5, and the number of the positioning assemblies 3 and the jacking assemblies 4 on the pair of wrench rods 1 is consistent. When the pair of wrench rods 1 is arranged on both sides of the two rows of cantilever reinforcements 6, there are positioning assemblies 3 and jacking assemblies 4 on both sides of each cantilever reinforcement 6, and as the pair of wrench rods 1 rotates towards each other, the positioning assemblies 3 and the jacking assemblies 4 are matched and plugged in to clamp and correct the cantilever reinforcement 6, and when the pair of wrench rods 1 is parallel, the two rows of cantilever reinforcements 6 are corrected and aligned synchronously.

[0041] If the two rows of cantilevered steel bars 6 on the top of the prefabricated component 5 are arranged in alignment, or only one row of cantilevered steel bars 6 is arranged, the positioning assembly 3 is arranged on one wrench rod 1, and the jacking assembly 4 is arranged on the other wrench rod 1, and the spacing of the positioning assembly 3, the spacing of the jacking assembly 4, and the spacing of the cantilevered steel bars 6 are kept consistent. If the number of rows of cantilevered steel bars 6 on the prefabricated component 5 is large, a plurality of prefabricated component cantilevered steel bar positioning auxiliary devices can be used to adjust the plurality of rows of cantilevered steel bars 6.

[0042] Please refer to the accompanying drawings Figure 1 and the accompanying drawings Figure 5 , the wrench rod 1 comprises a wrench rod 101 and a rotating rod 102, the rotating rod 102 is connected perpendicularly to one end of the wrench rod 101, and one end of the wrench rod 101 is rotatably inserted into the force transmission support 2 through the rotating rod 102; the positioning assembly 3 and the jacking assembly 4 are respectively sleeved on the wrench rod 101.

[0043] Preferably, the wrench rod 101 can be made of round steel, the length of the round steel is greater than the length of the prefabricated component 5, the rotating rod 102 can be made of steel with a diameter slightly smaller than the diameter of the wrench rod 101, the length of the rotating rod 102 is slightly greater than the height of the force transmission support 2, the rotating rod 102 is perpendicularly welded and fixed with the wrench rod 101, and the stable rotation of the wrench rod 101 relative to the force transmission support 2 through the rotating rod 102 is ensured.

[0044] Please refer to the accompanying drawings Figure 1 and the accompanying drawings Figure 2 , the force transmission support 2 is a hollow structure with one side open, and a plurality of insertion grooves 201 are formed at intervals at the two ends of the opening of the force transmission support 2, so that the two ends of the rotating rod 102 can be inserted into the insertion grooves 201, and the wrench rod 101 can rotate relative to the force transmission support 2 with the rotating rod 102 as the center.

[0045] Preferably, the force transmission support 2 can be made of channel steel, and the insertion grooves 201 are formed at the two ends of the opening of the channel steel for the insertion of the rotating rod 102, so that the wrench rod 101 can be connected with the force transmission support 2 through the rotating rod 102 and rotate relative to the force transmission support 2. The spacing of the insertion grooves 201 can be adjusted adaptively according to the lateral spacing of the cantilevered steel bars 6, so as to ensure that the spacing of the pair of wrench rods 1 after correction rotation matches the lateral spacing of the cantilevered steel bars 6, and the purpose of correcting the cantilevered steel bars 6 by the positioning assembly 3 and the jacking assembly 4 is achieved.

[0046] Please refer to the accompanying drawings Figure 2 , the insertion grooves 201 are arranged in an inclined U-shaped structure, the axial direction of the insertion grooves 201 and the axial direction of the force transmission support 2 form an acute angle, and the inclined directions of the insertion grooves 201 corresponding to the pair of wrench rods 101 are opposite.

[0047] By setting the insertion slot 201 obliquely, the wrench bar 101 can be prevented from being separated from the force transmission support 2 when the wrench bar 101 is rotated, and a pair of wrench bars 101 are relatively rotated through the insertion slots 201 in opposite directions to make the pair of wrench bars 101 approach or move away from the cantilevered steel bar 6.

[0048] Please refer to the attached Figure 3 and the attached Figure 5 The positioning assembly 3 comprises a first sleeve 301 and a first positioning rod 302. The first sleeve 301 is coaxially sleeved on the wrench bar 101 and locked by a bolt 7. One end of a pair of first positioning rods 302 is arranged on the outer sidewall of the first sleeve 301, and a positioning gap is formed between the pair of first positioning rods 302, in which the cantilevered steel bar 6 can be clamped, and the other end of the pair of first positioning rods 302 can be matched and inserted with the jacking assembly 4.

[0049] Preferably, the first sleeve 301 can be made of a round steel pipe with an inner diameter slightly larger than that of the wrench bar 101, so as to be easily sleeved on the wrench bar 101. A screw hole is reserved in the middle of the cylinder wall of the first sleeve 301, and after the first sleeve 301 is moved to the position of the cantilevered steel bar 6 on the wrench bar 101, the bolt 7 is screwed and vertically clamped on the wrench bar 101, locking the first sleeve 301 on the wrench bar 101. The first positioning rod 302 can be made of steel and welded on the outer sidewall of the first sleeve 301.

[0050] Please refer to the attached Figure 3 The positioning gap width of one end of the pair of first positioning rods 302 close to the first sleeve 301 is smaller than that of the other end away from the first sleeve 301, so that the first sleeve 301 and the pair of first positioning rods 302 are connected into a K-shaped structure.

[0051] The positioning gap width between the pair of first positioning rods 302 changes from wide to narrow, ensuring that the inclined cantilevered steel bar 6 can be guided and clamped into the wide end of the positioning gap, and the cantilevered steel bar 6 is gradually corrected to the narrow end of the positioning gap with the jacking of the jacking assembly 4, so as to realize the correction and adjustment of the cantilevered steel bar 6 by controlling the spacing between the narrow ends of the positioning gaps of the adjacent two groups of positioning assemblies 3.

[0052] Please refer to the attached Figure 4 and the attached Figure 5The jacking assembly 4 comprises a second sleeve 401, a connecting rod 402 and a second positioning rod 403. The second sleeve 401 is coaxially sleeved on the spanner rod 101 and locked by the bolt 7. One end of the connecting rod 402 is fixedly connected with the side wall of the second sleeve 401, and a plurality of second positioning rods 403 are spaced apart and connected on the other end of the connecting rod 402. The second positioning rods 403 form a splicing gap, and the other end of the first positioning rod 302 can be matched and spliced in the splicing gap. The other end of the connecting rod 402 abuts against the cantilever steel bar 6 and can jack the cantilever steel bar 6 into the positioning gap.

[0053] Preferably, the second sleeve 401 can be made of a round steel pipe with an inner diameter slightly larger than that of the spanner rod 101, so as to facilitate the sleeving of the second sleeve 401 on the spanner rod 101. The second sleeve 401 is provided with a screw hole in the middle of the sleeve wall. After the second sleeve 401 is moved to the position of the cantilever steel bar 6 on the spanner rod 101, the bolt 7 is screwed into the screw hole and vertically abuts against the spanner rod 101, thereby locking the second sleeve 401 on the spanner rod 101. The connecting rod 402 and the second positioning rod 403 can be made of steel bars, and the connecting rod 402 is fixedly welded with the outer side wall of the second sleeve 401 and the second positioning rod 403.

[0054] Please refer to the accompanying drawings Figure 4 The second positioning rod 403 is provided with four second positioning rods 403, which are symmetrically connected on both sides of the other end of the connecting rod 402. The upper and lower second positioning rods 403 on the same side of the other end of the connecting rod 402 form a splicing gap, and the two sides of the connecting rod 402 symmetrically form two splicing gaps, so that the other end of the first positioning rod 302 can be matched and spliced in the two splicing gaps.

[0055] The first positioning rod 302 is spliced in the splicing gap between the upper and lower second positioning rods 403. The first positioning rod 302 arranged transversely and the first positioning rod 302 arranged vertically form a transverse and vertical limiting splicing, which ensures stable splicing between the positioning assembly 3 and the jacking assembly 4, and prevents disengagement and deviation, so that the cantilever steel bar 6 is jacked into the narrow end of the positioning gap of the positioning assembly 3 by the jacking assembly 4.

[0056] Please refer to the accompanying drawings Figure 4 The splicing gap is close to the connecting rod 402, and the gap width is smaller than that away from the connecting rod 402, so that the four second positioning rods 403 form an X-shaped structure at the other end of the connecting rod 402.

[0057] The gap width of the splicing gap gradually decreases, which facilitates the guiding insertion of the first positioning rod 302 of the positioning assembly 3 into the splicing gap, and ensures the matching and accurate splicing of the positioning assembly 3 and the jacking assembly 4.

[0058] Please refer to the accompanying drawings Figure 1To the attached Figure 5 A method for assisting the positioning of precast components' cantilever reinforcement, comprising the following steps:

[0059] Please see the attached Figure 6 Step 1: A plurality of positioning assemblies 3 and a plurality of jacking assemblies 4 are sleeved on a pair of wrench rod members 1, and the positioning assemblies 3 and the jacking assemblies 4 are arranged alternately on each wrench rod member 1.

[0060] The spacing and number of the positioning assemblies 3 and the spacing and number of the jacking assemblies 4 are arranged correspondingly according to the spacing and number of the cantilever reinforcement 6, so as to ensure that each cantilever reinforcement 6 can be corrected by a set of positioning assemblies 3 and a set of jacking assemblies 4.

[0061] Step 2: According to the transverse spacing of the cantilever reinforcement 6 on the precast component 5, the positions of the positioning assemblies 3 and the jacking assemblies 4 are adjusted and locked by bolts 7, so that the positioning assemblies 3 on one of the wrench rod members 1 are arranged opposite to the jacking assemblies 4 on the other wrench rod member 1 on both sides of the cantilever reinforcement 6.

[0062] Step 3: One end of the pair of wrench rod members 1 is rotatably inserted into the force transmission support 2, and the spacing of the pair of wrench rod members 1 near the force transmission support 2 is smaller than the spacing away from the force transmission support 2.

[0063] Specifically, the two ends of the rotating rod 102 are respectively inserted into the insertion grooves 201 at the two ends of the opening of the force transmission support 2, so as to realize the rotation of the pair of wrench rod members 101 relative to the force transmission support 2, and the rotating directions of the pair of wrench rod members 101 are opposite.

[0064] Step 4: Rotate one of the wrench rod members 1, so that the plurality of positioning assemblies 3 on the wrench rod member 1 respectively clamp a plurality of cantilever reinforcements 6 on one side of the precast component 5 through the positioning gaps, to realize the preliminary correction of the cantilever reinforcements 6 on one side of the precast component 5, and the plurality of jacking assemblies 4 on the wrench rod member 1 are aligned with a plurality of cantilever reinforcements 6 on the other side of the precast component 5.

[0066] Step 5: Rotate the other wrench rod member 1, so that the plurality of positioning assemblies 3 on the wrench rod member 1 respectively clamp a plurality of cantilever reinforcements 6 on the other side of the precast component 5 through the positioning gaps, to realize the preliminary correction of the plurality of cantilever reinforcements 6 on the other side of the precast component 5, and the plurality of jacking assemblies 4 on the wrench rod member 1 are aligned with a plurality of cantilever reinforcements 6 on one side of the precast component 5.

[0067] The two rows of cantilevered steel bars 6 on both sides of the prefabricated component 5 are positioned and initially corrected in the same way, and the rotating directions of the two wrench rods 101 are opposite, so as to realize the separate positioning and initial correction of the two rows of cantilevered steel bars 6.

[0068] Please refer to the attached drawings Figure 7 , step 6: continue to rotate the pair of wrench rod members 1 until the pair of wrench rod members 1 are parallel to each other, so that the oppositely arranged jacking assembly 4 and the positioning assembly 3 are matched and inserted, and the jacking assembly 4 jacks the cantilevered steel bars 6 into the narrow end of the positioning gap of the positioning assembly 3, and the correction of the cantilevered steel bars 6 on both sides of the prefabricated component 5 is completed.

[0069] When the pair of wrench rod members 1 are parallel to each other, the position of the insertion joint of the jacking assembly 4 and the positioning assembly 3 is opposite to the pair of wrench rod members 1, so that the cantilevered steel bars 6 at the narrow end of the positioning gap, i.e. the insertion joint of the jacking assembly 4 and the positioning assembly 3, are opposite to the pair of wrench rod members 1, so as to correct and align the cantilevered steel bars 6 in the same row, and the correction of the two rows of cantilevered steel bars 6 on both sides of the prefabricated component 5 is simultaneously completed.

[0070] In order to ensure the correction effect, the pair of wrench rod members 1 should be arranged as close to the free end of the cantilevered steel bars 6 as possible, and the insertion length (about 20 mm) of the cantilevered steel bars 6 and the grouting sleeve of the prefabricated component 5 above should be left, i.e. the pair of wrench rod members 1 are located about 20 mm below the free end of the cantilevered steel bars 6, so as to facilitate the alignment of the prefabricated component 5 above.

[0071] Please refer to the attached drawings Figure 8 , step 7: hoist the prefabricated component 5 above, so that the cantilevered steel bars 6 of the prefabricated component 5 below are inserted into the grouting sleeve of the prefabricated component 5 above.

[0072] When hoisting the prefabricated component 5 above, the swing amplitude of the prefabricated component 5 should be controlled, and the prefabricated component 5 above is stopped at about 50 mm above the cantilevered steel bars 6 of the prefabricated component 5 below, and then the grouting sleeve of the prefabricated component 5 above is aligned with the cantilevered steel bars 6 of the prefabricated component 5 below, and then the prefabricated component 5 above is slowly lowered, so as to ensure the one-to-one alignment and insertion of the cantilevered steel bars 6 and the grouting sleeve.

[0073] Step 8: rotate the pair of wrench rod members 1, so that the pair of wrench rod members 1 are away from each other, the positioning assembly 3 and the jacking assembly 4 are separated from the cantilevered steel bars 6, the wrench rod members 1, the force transmission support 2, the positioning assembly 3 and the jacking assembly 4 are removed, and the prefabricated component 5 above is lowered until it is installed.

[0074] Please refer to the attached drawings Figure 9When hoisting the prefabricated component 5 above, a cushion block 501 can be arranged on the top of the prefabricated component 5 below, so that the prefabricated component 5 above falls on the cushion block 501, and is used for roughly adjusting the hoisting verticality of the prefabricated component 5 above; then an inclined support (not shown in the figure) is installed between the prefabricated component 5 above and the fixed surface such as the ground, so that the prefabricated component 5 above is accurately adjusted in assembly verticality through the inclined support to meet the installation requirements, and the vertical assembly precision of the prefabricated component 5 is ensured.
