Description

Technical Field

[0001] This invention relates to the field of building construction equipment technology. More specifically, this invention relates to a method for binding the reinforcing bars of connecting beams between prefabricated composite slabs. Background Technology

[0002] With the acceleration of the industrialization of construction, prefabricated buildings are springing up like mushrooms after rain. In the construction of prefabricated buildings, composite slab support systems are widely used. During composite slab construction, it is necessary to tie reinforcing bars. Reinforcing bar tying requires workers to pass the reinforcing bar binding wire under the intersection of two reinforcing bars, hook the wire with a reinforcing bar hook, cross and wrap the wire, and rotate both ends of the wire to secure it. In existing technology, the length of the reinforcing bar binding hook cannot be changed, which limits the scope of application of the reinforcing bar tying device. Summary of the Invention

[0003] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0004] Another objective of this invention is to provide a method for tying reinforcing bars in connecting beams between prefabricated composite slabs, which expands the application range of the reinforcing bar tying device by setting an adjustment component to adjust the length of the reinforcing bar tying device.

[0006] Step 1: Construct the bottom support of the connecting beam, build the bottom plate of the beam on the bottom support, and build the composite slab support on the bottom support. On the bottom plate of the beam, erect the steel beam binding frame, and bind the bottom reinforcement, stirrups and web reinforcement of the connecting beam to the steel beam binding frame.

[0007] Step 2: Install the composite slab on the composite slab support, with the reinforcing bars on both sides of the composite slab staggered, and tie the beam top reinforcement.

[0008] The bottom reinforcement, stirrups, web reinforcement, and top reinforcement of the beam are tied using a rebar tying device. The rebar tying device includes a gun-shaped housing, inside which is a rotary motor. The output shaft of the rotary motor is connected to a connecting block, and the end of the connecting block is connected to a drive gear. A positioning cylinder is connected to the drive gear, and an adjustment assembly is provided inside the positioning cylinder. The adjustment assembly includes a pair of first grooves formed by recesses in the inner sidewall of the positioning cylinder, a first spring located in the first groove, a drive block connected to the end of the first spring, a drive box located on the outer sidewall of the positioning cylinder, a drive rod that slides up and down inside the drive box, a second spring connected to the drive rod, and a fixed pulley located at the top of the drive box. A thin rope is connected to the lower end of the drive rod, and the thin rope passes through the fixed pulley and is connected to the upper end of the drive block. A tying hook is inserted inside the positioning cylinder, and multiple pairs of receiving grooves are formed by recesses in the tying hook.

[0009] Preferably, the end of the gun-shaped housing is detachably connected to a positioning shell, the drive gear is located inside the positioning shell, the output shaft of the rotary motor is connected to a connecting block, the connecting block is located inside the gun-shaped housing, the end of the connecting block is recessed to form a receiving groove with a triangular cross-section, a first connecting rod with a triangular cross-section is inserted into the receiving groove, the first connecting rod is connected to the drive gear, a second connecting rod is connected to the drive gear, the second connecting rod rotates through the side wall of the positioning shell through a bearing and is detachably connected to the positioning cylinder.

[0010] Preferably, the positioning cylinder is provided with two third limiting plates spaced apart, the third limiting plates are provided with third fixing holes, and the end of the second connecting rod is provided with two third threaded holes spaced apart. The third threaded holes and the third fixing holes are detachably connected by third bolts.

[0011] Preferably, the positioning shell is provided with two second limiting plates at intervals, the second limiting plates are provided with second fixing holes, and the gun-shaped shell is provided with two second threaded holes at intervals. The second fixing holes and the second threaded holes are detachably connected by second bolts.

[0012] Preferably, the positioning housing has a driven gear rotatably connected to the positioning housing. A drive hole is provided through the center of the driven gear, and the sidewall of the drive hole is recessed at intervals to form multiple grooves. An adjusting cylinder is horizontally provided above the gun-shaped housing, and the adjusting cylinder is connected to the positioning housing. A push rod is slidably provided inside the adjusting cylinder. Multiple elongated protrusions are provided circumferentially at intervals on the sidewall of the push rod. The protrusions are arranged along the length direction of the push rod. The push rod passes through the drive hole, and the multiple protrusions pass through the multiple grooves one by one. Two fourth threaded holes are provided at intervals at the end of the push rod. The fourth threaded holes and the third fixing hole can be detachably connected by the third bolt. The sidewall of the adjusting cylinder has an elongated opening along its length direction, and an adjusting rod is provided on the push rod. The adjusting rod passes through the opening to drive the push rod to move.

[0013] Preferably, the end of the adjusting rod is provided with a pair of positioning plates, the positioning plates are provided with through holes, and the adjusting cylinder is provided with multiple pairs of first threaded holes along its length direction. The through holes and the first threaded holes are detachably connected by first bolts to facilitate fixing the adjusting rod. The two positioning plates are provided with a gripping block.

[0014] Preferably, the positioning shell has two sets of sliding holes, and a positioning rod is slidably installed in each set of sliding holes. The two sets of sliding holes are located on the front and rear side walls of the positioning shell, respectively. The ends of the same set of positioning rods are provided with a support block. The support block is provided with an annular first slide rail. The driven gear is provided with two first sliders, and the two first sliders are slidably connected to the two first slide rails in a one-to-one correspondence. When the positioning rod drives the driven gear to be aligned with the driving gear, the driving gear meshes with the driven gear so that the driving gear can drive the driven gear to rotate.

[0015] Preferably, the positioning rod has two through holes, and the driven gear is fixed by inserting pins into the corresponding through holes.

[0016] The present invention has at least the following beneficial effects:

[0017] First, the present invention expands the application range of the rebar tying device by setting an adjustment component to adjust the length of the rebar tying device; it adjusts the length of the tying hook by setting a first groove, a receiving groove, and a driving block; and it adjusts the position of the driving block by setting a driving box, a driving rod, a fixed pulley, a first spring, and a second spring.

[0018] Secondly, by setting a connecting block and a first connecting rod with a triangular cross-section, the present invention can not only separate the gun housing from the positioning housing, but also drive the active gear to rotate when the gun housing and the positioning housing are connected; the detachable connection between the positioning housing and the gun housing is beneficial for the maintenance of the rebar binding device.

[0019] Third, the present invention can effectively achieve a wide range of adjustable length of the rebar tying device to expand its application range; by setting a driven gear, only one motor is needed to drive the driven gear to rotate; by setting a protrusion and a groove, the push rod can not only move left and right relative to the driven gear, but also rotate with the driven gear; the adjusting cylinder is located above the gun-shaped housing; compared with the prior art that makes the rotary motor and the driven gear coaxial, this setting has a larger adjustment range; and the push rod is driven to move by setting an adjusting rod.

[0020] Fourth, when it is necessary to connect the positioning cylinder to the end of the push rod, the positioning rod is moved until the driven gear meshes with the driving gear, so that the driving gear drives the driven gear to rotate. When it is only necessary to connect the positioning cylinder to the end of the second connecting rod, the positioning rod is moved to separate the driven gear from the driving gear. At this time, only the driving gear rotates. This setting can effectively reduce the workload of the rotary motor, extend the service life of the rotary motor, and also reduce the wear on the driven gear, thus extending the service life of the driven gear.

[0021] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0030] like Figure 1-7 As shown, the present invention provides a method for binding the reinforcing bars of the connecting beam between prefabricated composite slabs, comprising the following steps:

[0031] Step 1: Construct the bottom support of the connecting beam, build the bottom plate of the beam on the bottom support, and build the composite slab support on the bottom support. On the bottom plate of the beam, erect the steel beam binding frame, and bind the bottom reinforcement, stirrups and web reinforcement of the connecting beam on the steel beam binding frame.

[0032] Step 2: Install the composite slab on the composite slab support, with the reinforcing bars on both sides of the composite slab staggered, and tie the beam top reinforcement.

[0033] The bottom reinforcement, stirrups, web reinforcement, and top reinforcement of the beam are tied using a rebar tying device. This device includes a gun-shaped housing 1, within which a rotary motor 2 is housed. A connecting block 5 is connected to the end of the output shaft of the rotary motor 2. A drive gear 7 is connected to the end of the connecting block 5. A positioning cylinder 9 is connected to the drive gear 7. An adjusting assembly is located within the positioning cylinder 9. This adjusting assembly includes a pair of first grooves 27 formed by recesses in the inner wall of the positioning cylinder 9, and a first spring 2 disposed within each of the first grooves 27. 8. A drive block 29 connected to the end of the first spring 28, a drive box 22 located on the outer wall of the positioning cylinder 9, a drive rod 23 slidably disposed in the drive box 22, a second spring 24 connected to the drive rod 23, and a fixed pulley 25 located at the top of the drive box 22. A thin rope 26 is connected to the lower end of the drive rod 23. The thin rope 26 passes through the fixed pulley 25 and is connected to the upper end of the drive block 29. A hook 10 is inserted into the positioning cylinder 9. Multiple pairs of receiving grooves 31 are formed by recesses at intervals on the hook 10.

[0034] In this technical solution, a beam bottom support is constructed for the connecting beam, a beam bottom plate is built on the beam bottom support, and a composite slab support is built on the beam bottom support. A steel beam binding frame is erected on the beam bottom plate, and the bottom reinforcement, stirrups, and web reinforcement of the connecting beam are bound on the steel beam binding frame. The overlapping order of the longitudinal and transverse beams and the anchorage of the beam reinforcement into the wall and column are considered. A composite slab is installed on the composite slab support, and the steel reinforcements of the two composite slabs on both sides are staggered. The beam top reinforcement is bound. The switch of the rotary motor 2 is located at the handle of the gun-shaped housing 1. The output shaft of the rotary motor 2 is horizontally set, and the two first grooves 27 are symmetrically arranged along the central axis of the positioning cylinder 9. The end of the second spring 24 is connected to the bottom of the drive box 22. The positioning cylinder 9 has two thread holes, which are connected to two first grooves 27 in a one-to-one manner. A thin thread passes through the thread holes. When the driving rod 23 is pressed down and no longer moves, the driving block 29 is located in the first groove 27, and the second spring 24 is in a contracted state, while the first spring 28 is in a contracted state. The hook 10 can slide along the positioning cylinder 9. When the driving rod 23 is not pressed down, the first spring 28 and the second spring 24 are in an extended state. The driving block 29 is partially located in the first groove 27 and partially located in the receiving groove 31. At this time, the hook 10 is fixed, and the end of the hook is bent, which is not shown in the figure.

[0035] During use, based on the usage conditions of the rebar tying device (e.g., the user's height, rebar tying position), the length of the hook 10 is adjusted, that is, the appropriate receiving groove is selected to accommodate the drive block 29 to fix the hook 10.

[0036] By adopting this technical solution, the present invention expands the application range of the rebar tying device by setting an adjustment component to adjust the length of the rebar tying device; the length of the tying hook 10 is adjusted by setting a first groove 27, a receiving groove, and a driving block 29; and the position of the driving block 29 is adjusted by setting a driving box 22, a driving rod 23, a fixed pulley 25, a first spring 28, and a second spring 24.

[0037] In another technical solution, the end of the gun-shaped housing 1 is detachably connected to a positioning shell 8. The drive gear 7 is located inside the positioning shell 8. The output shaft of the rotary motor 2 is connected to a connecting block 5. The connecting block 5 is located inside the gun-shaped housing 1. The end of the connecting block 5 is recessed to form a receiving groove with a triangular vertical cross-section. A first connecting rod 6 with a triangular vertical cross-section is inserted into the receiving groove (when the gun-shaped housing 1 is connected to the positioning shell 8, the first connecting rod 6 is located in the receiving groove; when the gun-shaped housing 1 is separated from the positioning shell 8, the first connecting rod 6 is separated from the receiving groove). The first connecting rod 6 is connected to the drive gear 7 (the first connecting rod 6 is perpendicular to the drive gear 7). A second connecting rod 19 is connected to the drive gear 7 (the second connecting rod 19 is perpendicular to the drive gear 7). The second connecting rod 19 is rotatably connected through a bearing through the side wall of the positioning shell 8 and is detachably connected to the positioning cylinder 9. By adopting this technical solution, the present invention can not only separate the gun-shaped housing 1 from the positioning housing 8 by setting the connecting block 5 and the first connecting rod 6 with a triangular cross section, but also drive the active gear 7 to rotate when the gun-shaped housing 1 and the positioning housing 8 are connected; the detachable connection between the positioning housing 8 and the gun-shaped housing 1 is beneficial for the maintenance of the rebar binding device.

[0038] In another technical solution, the positioning cylinder 9 is provided with two third limiting plates 20 spaced apart, and each third limiting plate 20 is provided with a third fixing hole. The end of the second connecting rod 19 is provided with two third threaded holes spaced apart, and the third threaded holes and the third fixing holes are detachably connected by third bolts 21. This technical solution achieves a detachable connection between the positioning cylinder 9 and the second connecting rod 19.

[0039] In another technical solution, the positioning shell 8 is provided with two second limiting plates spaced apart, and the second limiting plates are provided with second fixing holes. The gun-shaped housing 1 (end) is provided with two second threaded holes spaced apart. The second fixing holes and the second threaded holes are detachably connected by second bolts. This technical solution achieves a detachable connection between the positioning shell 8 and the gun-shaped housing 1.

[0040] In another technical solution, a driven gear 12 is provided inside the positioning housing 8 (the center line of the driven gear 12 is parallel to the center line of the driving gear 7). The driven gear 12 is rotatably connected to the positioning housing 8. A drive hole is provided through the center of the driven gear 12. The sidewall of the drive hole is recessed to form multiple grooves 33. An adjusting cylinder 3 is horizontally provided above the gun-shaped housing 1. The adjusting cylinder 3 is connected to the positioning housing 8. A push rod 4 is slidably provided inside the adjusting cylinder 3. Multiple elongated protrusions 32 are provided circumferentially on the sidewall of the push rod 4. The length of the protrusions 32 is the same as the length of the push rod 4. The protrusions 32 are arranged along the length direction of the push rod 4. The push rod 4 passes through the grooves 33. The drive hole and multiple protrusions 32 pass through multiple grooves 33 in a one-to-one correspondence. The end of the push rod 4 is provided with two fourth threaded holes at intervals. The fourth threaded holes and the three fixing holes can be detachably connected by the third bolt 21 (when the positioning cylinder 9 is connected to the second connecting rod 19, the third threaded hole and the third fixing hole are detachably connected by the third bolt 21; when the positioning cylinder 9 is connected to the push rod 4, the fourth threaded hole and the three fixing holes are detachably connected by the third bolt 21). The side wall of the adjusting cylinder 3 is provided with an elongated opening 34 along its length direction. The push rod 4 is provided with an adjusting rod, which passes through the opening 34 to drive the push rod 4 to move. By adopting this technical solution, the present invention can effectively achieve a wide range of adjustable length of the rebar tying device, thereby expanding its application range; by setting the driven gear 12, only one motor is needed to drive the driven gear 12 to rotate; by setting the protrusion 32 and the groove 33, the push rod 4 can not only move left and right relative to the driven gear 12, but also rotate with the driven gear 12; the adjusting cylinder 3 is located above the gun-shaped housing 1. Compared with the prior art where the rotary motor 2 and the driven gear 12 are coaxial, this setting has a larger adjustment range; the push rod 4 is driven to move by setting the adjusting rod.

[0041] In another technical solution, the end of the adjusting rod is provided with a pair of positioning plates 35 (the adjusting rod is perpendicular to the positioning plates 35). Each positioning plate 35 has a through hole 36. The adjusting cylinder 3 has multiple pairs of first threaded holes spaced apart along its length. The through holes 36 and the first threaded holes are detachably connected by first bolts to fix the adjusting rod (based on the required length of the hook 10, the through hole 36 is connected to the first threaded hole at a suitable position). Both positioning plates 35 share a gripping block 37. Using this technical solution, the present invention achieves the fixation of the adjusting rod's position by setting the positioning plates 35, and facilitates the movement of the adjusting rod by setting the gripping block 37.

[0042] In another technical solution, the positioning shell 8 is provided with two sets of sliding holes (each set of sliding holes includes multiple sliding holes), and a positioning rod 13 is slidably installed in each set of sliding holes. The two sets of sliding holes are located on the front side wall and the rear side wall of the positioning shell 8, respectively (the front side wall is the side wall facing the gun-shaped housing 1, and the rear side wall is the side wall away from the gun-shaped housing 1, with the driven gear 12 located between the two sets of sliding holes). The ends of the same set of positioning rods 13 are provided with a support block 14 (the support block 14 is located inside the positioning shell 8, and the support block 14 is annular), and the support block 14 is provided with an annular first slide rail 15. The driven gear 12 is provided with two first sliders 16 (the two first sliders 16 are respectively located on two surfaces of the driven gear 12). The two first sliders 16 are slidably connected to two second slide rails in a one-to-one correspondence. When the positioning rod 13 drives the driven gear 12 to be aligned with the driving gear 7, the driving gear 7 meshes with the driven gear 12 so that the driving gear 7 can drive the driven gear 12 to rotate. When the positioning rod 13 drives the driven gear 12 to separate from the driving gear 7, the rotation of the driving gear 7 no longer affects the driven gear 12. By adopting this technical solution, when it is necessary to connect the end of the positioning cylinder 9 to the end of the push rod 4, the positioning rod 13 is moved until the driven gear 12 meshes with the driving gear 7, so that the driving gear 7 drives the driven gear 12 to rotate. When it is only necessary to connect the end of the positioning cylinder 9 to the end of the second connecting rod 19, the positioning rod 13 is moved to separate the driven gear 12 from the driving gear 7. At this time, only the driving gear 7 rotates. This setting can effectively reduce the workload of the rotary motor 2, extend the service life of the rotary motor 2, and also reduce the wear on the driven gear 12, thus extending the service life of the driven gear 12.

[0043] In another technical solution, the positioning rod 13 has two through holes 18 (the two through holes 18 are spaced apart along the length of the positioning rod 13), and the driven gear 12 is fixed by inserting pins 17 into the corresponding through holes 18 (the positioning rod 13 is fixed, thus fixing the driven gear 12). This technical solution achieves the fixing of the driven gear 12.
