Description

Technical Field

[0001] The present invention belongs to the technical field of steel bar binding devices, and in particular relates to a shaft steel bar rotation binding device and method which are easy to use. Background Art

[0002] At present, prefabricated inspection wells are widely used in municipal engineering to speed up the construction progress. During the construction of housing projects, some concrete pouring residues will be left on site, which will be treated as construction waste in the past, causing great pressure on the environment. At the same time, some steel bar residues will be left. When the inspection wells of the outdoor pipeline network project affiliated to the housing project are constructed, the number of inspection wells required is small. If purchased from the market, the bargaining power is weak, which is not conducive to cost control. Therefore, the remaining concrete and steel bar residues on site can be used to build a production workshop at the project site to produce prefabricated inspection well shafts.

[0003] The shaft is generally circular, with double-layer steel bars, and the spacing between the two layers is 100mm. At the same time, spiral stirrups are wrapped around the outermost steel bars. The general construction method is that one person erects the steel bars on the ground, and one person pulls the steel bars with a diameter of 6mm in his hand and ties them with the vertical steel bars of another person at the intersection, and so on for preliminary fixation, and then the spiral stirrups are wrapped and fixed on the vertical steel bars. After completion, the formwork can be reinforced and concrete can be poured.

[0004] The above construction method has the following problems: First, the work efficiency is low, and it needs to be tied twice. The first time is to preliminarily fix the vertical steel bars for subsequent operations, and the second time is to wrap the spiral stirrups around the vertical steel bars. Both operations require the operator to circle around the shaft, which is time-consuming and laborious. Second, the accuracy is poor. The positioning of the vertical steel bars is mainly determined by the positioning points previously engraved on the ground, such as chalk engraving. The operation process will inevitably erase the engraved points, resulting in redrawing. This process is repeated for a long time, which will inevitably cause the position of the engraved points to shift, resulting in poor steel bar forming quality. Summary of the invention

[0005] The purpose of the present invention is to provide a shaft steel bar rotary binding device which is easy to use and is used to solve the technical problems of low efficiency of on-site steel bar binding and poor quality of shaft steel bar forming. The device provided by the present invention can improve work efficiency and is simple to manufacture.

[0008] Further preferably, it also includes a crank, which is fixed on the rotating shaft. The operator drives the rotating shaft to rotate by turning the crank, and the rotating shaft drives the disc one and the disc two to rotate, and then the main reinforcement also rotates. At this time, other operators can tie the stirrups.

[0011] Further preferably, a back rib is provided on the opposite sides of disk one and disk two after installation, and the back rib is respectively fixed to disk one and disk two by clamps, and the back rib is a cross structure, the center of the back rib of disk one passes through rotating shaft one, and the center of the back rib of disk two passes through rotating shaft two, disk two is fixedly connected to rotating shaft two through the back rib, and disk one is fixedly connected to rotating shaft one through the back rib.

[0012] Further preferably, each circular hole of the disc is provided with a fixed support, and the fixed support includes a vertical part and a horizontal part, and is L-shaped as a whole. The vertical part is fixed at the position of the circular hole of the disc and is arranged in a circle around the circular hole. The horizontal part is fixedly connected to the vertical part. After one end of the steel bar is inserted into the circular hole of the disc, the other end is suspended in the air and may slide out of the circular hole. By adding a fixed support to each circular hole, the function of supporting the main reinforcement in coordination with the circular hole can be achieved, and the main reinforcement will not slide out of the circular hole through the support of the fixed support.

[0013] Further preferably, the length of the horizontal portion is not less than one third of the wellbore height, so that the fixed support member can play a better supporting role.

[0014] Further preferably, steel pipes are provided on the top of bracket one and bracket two, and the steel pipes are respectively sleeved on the outside of rotating shaft one and rotating shaft two, two cross bars are provided at the bottom of bracket two, a connecting rod is provided between the two cross bars, and the steel pipe extending out of disc two at the top of bracket two is respectively connected to the two cross bars through inclined rods.

[0015] Further preferably, the steel pipe extending out of the disc at the top of the bracket is connected to a cross rod through a vertical rod, and the cross rod is located on a stable platform.

[0016] A convenient shaft steel bar rotation binding method is implemented by any of the convenient shaft steel bar rotation binding devices described above, comprising the following steps: S1. After the circular holes of disk 1 and disk 2 are punched, the center of disk 2 is passed through shaft 2 and fixed at the designed position on the top of the bracket. Disk 1 is first installed at a position 50mm horizontally from the designed position on the top of the bracket. It is required that the relative distance between disk 1 and disk 2 after installation is greater than the length of the main reinforcement. S2, inserting one end of a plurality of main ribs into the circular holes of the first disk in sequence, then pushing the first disk to the designed position of the bracket and fixing it, and inserting the other ends of the plurality of main ribs into the circular holes of the second disk during the process of pushing the first disk toward the second disk; S3, synchronously rotate the disc 1 and the disc 2, and drive the main reinforcement to rotate together during the rotation of the disc 1 and the disc 2; S4. The operator holds the stirrups and wraps and ties them around each main reinforcement in turn; S5. After the binding is completed, remove the disc 1 from the bracket, and then remove the bound shaft steel bars.

[0017] After the shaft steel bars are removed, the next step of formwork support and concrete pouring can be carried out.

[0018] The present invention has the following beneficial effects: 1. The setting of disc one and disc two increases the efficiency of shaft reinforcement binding exponentially compared with the traditional method, changing "human movement" into "device rotation", and qualitatively improving the overall binding efficiency.

[0019] 2. Drill holes on the disc in advance to ensure firm fixation of the main reinforcement points. On the other hand, it avoids the traditional method of using chalk or other tools to carve on the ground, which can easily become blurred after repeated operations, thereby improving the accuracy of binding positioning.

[0020] 3. The purpose of using fixed supports is to support the main reinforcement in coordination with the circular holes. Since the main reinforcement is heavy, it is difficult to fix it firmly with a single circular hole. The addition of fixed supports significantly increases the support length of the main reinforcement, allowing it to be basically installed in place without obvious displacement.

The shaft is rotated by turning the crank, and the shaft drives the disc 1 11 and the disc 2 12 to rotate synchronously. During the rotation of the disc 1 11 and the disc 2 12, the main reinforcement inserted into the disc 1 11 and the disc 2 12 will rotate together, and the operator can tie the stirrups at this time. In the absence of the crank, the operator can rotate the disc 1 11 or the disc 2 12 nearby, thereby driving the shaft to rotate, and during the rotation of the shaft, the disc 2 12 or the disc 1 11 is driven to rotate, and during the rotation of the disc 1 11 and the disc 2 12, the main reinforcement is driven to rotate synchronously.

[0039] In the second embodiment, the bracket includes a bracket 1 21 and a bracket 22, the center of the disk 1 1 is fixedly connected with a rotating shaft 1 41, the rotating shaft 2 42 is coaxially movably connected with the rotating shaft 1 41, the rotating shaft 1 41 is movably connected to the bracket 1 21, the rotating shaft 2 42 is fixedly connected to the bracket 22, and the disk 1 is movably connected to the rotating shaft 2 through the rotating shaft 1.

[0040] A back rib 7 is provided on the opposite sides of the disk 11 and the disk 2 12 after installation. The back rib 7 is respectively fixed to the disk 11 and the disk 2 12 by a clamp 71. The back rib 7 is a cross structure. The center of the back rib 7 of the disk 11 passes through the rotating shaft 1 41, and the center of the back rib 7 of the disk 2 12 passes through the rotating shaft 2 42. The disk 2 12 is fixedly connected to the rotating shaft 2 42 through the back rib 7, and the disk 1 11 is fixedly connected to the rotating shaft 1 41 through the back rib 7.

[0041] When in use, after the disk 11 is pushed into the designed position, the groove 6 and the protrusion 51 of the locking mechanism 5 are aligned, and the locking mechanism 5 is locked using the bolt 53. In this way, the locking mechanism 5 realizes the movable connection between the rotating shaft 1 41 and the rotating shaft 2 42. If it is necessary to cancel the connection between the rotating shaft 1 41 and the rotating shaft 2 42, it is only necessary to loosen the bolt 53.

[0042] In embodiment three, a back rib 7 is provided on the side of disk one 11 and disk two 12 where there is no circular hole 3. The back rib 7 is respectively fixed to disk one 11 and disk two 12 by clamps 71. The back rib 7 is a cross structure. The center of the back rib 7 of disk one 11 passes through the rotating shaft one 41, and the center of the back rib 7 of disk two 12 passes through the rotating shaft two 42. Disk two 12 is fixedly connected to rotating shaft two 42 via the back rib 7, and disk one 11 is fixedly connected to rotating shaft one 41 via the back rib 7.

[0043] Each circular hole 3 of the disk 11 is provided with a fixed support 111, which includes a vertical part and a horizontal part, and is L-shaped as a whole. The vertical part is fixed at the position of the circular hole 3 of the disk 11 and is arranged in a circle around the circular hole 3. The horizontal part is fixedly connected to the vertical part, and the length of the horizontal part is not less than one third of the height of the wellbore.

[0044] When in use, the disc 11 and the disc 2 12 can be prevented from deformation by setting the back rib 7. After the holes of the disc 11 and the disc 2 12 are punched, the disc 2 12 is welded to the shaft 2 42 through the back rib 7, and the back rib 7 of the disc 11 is welded to the shaft 1 41. Then the shaft 1 41 is installed on the bracket 1 21, and the shaft 2 42 is installed on the bracket 2 22. Before the shaft 1 41 and the shaft 2 42 are not connected, the main reinforcement is inserted into the circular hole 3 of the disc 1 11. Since the main reinforcement is long and heavy, it is easy to fall out after being inserted into the circular hole 3 of the disc 1 11. By setting the fixed support 111, the main reinforcement can be supported.

[0045] In the fourth embodiment, steel pipes are arranged on the top of the bracket 1 21 and the bracket 2 22, and the steel pipes are respectively sleeved on the outside of the rotating shaft 1 41 and the rotating shaft 2 42. Two cross bars 221 are arranged on the bottom of the bracket 22, and a connecting rod 222 is arranged between the two cross bars 221. The steel pipe extending out of the disc 2 12 on the top of the bracket 22 is connected to the two cross bars 221 through the inclined rod 223.

[0046] The steel pipe extending out of the top of the bracket 21 from the disc 11 is connected to a cross rod 212 through a vertical rod 211, and the cross rod 212 is located on a stable platform.

[0047] In this embodiment, the thickness of disk 1 11 and disk 2 12 is 50 mm. According to actual conditions, a circular hole 3 is drilled in disk 11 and disk 2 12. The depth of the circular hole 3 is 25 mm. The different landing methods of bracket 1 and bracket 2 facilitate the separation of bracket 1 and bracket 2. Bracket 2 forms a triangular stable structure through the inclined rod 223 and the connecting rod 222, which can well maintain the stability of bracket 2.

[0048] When in use, bracket one 21 and bracket two 22 can each be firmly seated on the ground, the steel pipe arranged on the top of bracket one 21 is used to insert rotating shaft one 41, and the steel pipe arranged on the top of bracket two 22 is used to insert rotating shaft two 42.

[0049] Embodiment 5, a convenient method for rotating and tying shaft steel bars, is implemented by any of the convenient rotating and tying shaft steel bars devices described above, and comprises the following steps: S1, after the circular holes 3 are punched in the disc 11 and the disc 2 12, the center of the disc 2 12 is passed through the rotating shaft 2 42 and fixed at the designed position on the top of the bracket. The disc 11 is first installed at a position 50 mm horizontally away from the designed position on the top of the bracket. It is required that the relative distance between the disc 11 and the disc 2 12 after installation is greater than the length of the main reinforcement. The distance between the designed positions of the disc 11 and the disc 2 12 is the length of the main reinforcement; S2, inserting one end of a plurality of main ribs into the circular hole 3 of the disc 11 in sequence, then pushing the disc 11 to the designed position of the bracket and fixing it, and in the process of pushing the disc 11 to the disc 2 12, inserting the other ends of the plurality of main ribs into the circular hole 3 of the disc 2 12; S3, synchronously rotating the disc 11 and the disc 2 12, wherein the disc 11 and the disc 2 12 drive the main ribs to rotate together during the rotation process; S4. The operator holds the stirrups and wraps and ties them around each main reinforcement in turn; S5. After the binding is completed, the disc 11 is removed from the bracket, and then the bound shaft steel bars are removed.

[0050] It should be noted that the shaft reinforcement is double-layer reinforcement, and each layer needs to be tied with stirrups. Double-layer holes are set on disc one and disc two. A set of disc one and disc two can be used to tie the inner and outer steel bars of the shaft. In the specific operation, the inner main reinforcement is installed first, and then the inner stirrups are tied. After the inner shaft reinforcement is removed, the outer main reinforcement is installed, and then the outer stirrups are tied. Finally, the outer steel bar of the shaft is removed.

[0051] In the current municipal engineering construction, prefabricated inspection wells are widely used. In the construction of outdoor pipeline projects affiliated to building construction, due to the small quantity required, purchasing from the market faces cost pressure. There are a large number of waste concrete and steel bars at the construction site. It becomes very cost-effective to collect them and process them in the project's own workshop to produce wells. However, the traditional steel bar binding method has the disadvantages of low efficiency and poor precision.

[0052] The use of the present invention can realize an exponential increase in the binding efficiency, and the disc drilling position is accurate, thereby avoiding deviation in the binding position of the steel bars.

[0053] The above is only a specific implementation of the present invention, which enables those skilled in the art to understand or implement the present invention. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
