Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a complex concrete reinforcement binding auxiliary device and method. Background Art

[0002] In recent years, with the rapid development of my country's social economy, while urban buildings are constantly developing towards high altitudes, the development and utilization of underground space has also become an important direction, such as underground shopping malls, underground parking lots, underground high-speed rail stations, etc. The deep foundation pit engineering involved in the development of underground space is a very complex system engineering. In order to ensure the stability of the foundation pit, it is usually necessary to set up a support structure before excavation to effectively control the deformation of the foundation pit.

[0003] The existing support structure methods mainly include steel support, concrete support and mixed support of steel and concrete. In view of the large area and depth of the foundation pit in the construction of underground high-speed railway stations, steel support is difficult to meet the force requirements of the support structure, and multiple concrete supports are often set up. The concrete supports are fixed to the underground continuous wall on both sides of the foundation pit to support the slope. However, due to the interlacing of concrete structures, there are generally problems in the steel bar binding stage, such as large restrictions on the construction of steel bar insertion, low steel bar binding accuracy, steel bar binding conflicts, high labor time cost, and low binding efficiency, which in turn causes the concrete support structure strength to be lower than the design value, and unfavorable factors such as increased construction costs and extended construction period.

[0004] How to solve the above technical problems is the subject faced by the present invention. Summary of the invention

[0005] In order to solve the deficiencies of the prior art, the present invention provides a complex concrete steel bar tying auxiliary device and method which improves the steel bar tying accuracy and efficiency, has high structural strength and low construction cost.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] On the one hand, the present invention provides a complex concrete reinforcement binding auxiliary device, including a supporting structure and a guiding structure, wherein the supporting structure includes a column, a deadweight block and a plurality of joints, the column and the deadweight block are vertically arranged, and a plurality of joints are welded to the column, and the guiding structure includes a steering block, a sleeve and a connecting rod, the steering block is welded to the sleeve, and one end of the connecting rod is connected to the joint, and the other end is connected to the steering block.

[0008] Preferably, the deadweight block is provided with a groove adapted to the cross-sectional shape and size of the column, the groove is provided with an internal thread, the column is provided with an external thread at one end close to the deadweight block, and the column is threadedly connected to the deadweight block.

[0009] The internal thread in the groove of the deadweight block cooperates with the external thread at the end of the column, so that construction workers can easily and accurately adjust the height of the column to accurately adapt to the needs of steel bar binding at different heights and positions.

[0010] Preferably, the plurality of joints are evenly distributed along the axial and circumferential directions of the column.

[0011] Preferably, through holes of the same shape and size are provided at both ends of the connecting rod, at a side of the joint close to the connecting rod, and at a side of the steering block close to the connecting rod, and the connecting rod is connected to the joint and the steering block with bolts.

[0012] Preferably, cavities are symmetrically formed on both sides of the through holes of the joint and the steering block along the tangent direction.

[0013] The through holes of the joint and the steering block are provided with cavities. At the same time, the connecting rod is bolted to the joint and the steering block respectively, and the extension angle of the connecting rod can be adjusted and fixed to ensure that the sleeve is located in the same thread. Multiple sleeves in the same thread ensure the insertion path of the steel bars, avoid collision and obstruction of the steel bars, reduce the difficulty of side reinforcement insertion, and realize the synchronous insertion and fixation of multiple steel bars from bottom to top, which improves the installation efficiency and accuracy.

[0014] Preferably, the inner diameter of the sleeve is adapted to the outer diameter of the steel bar.

[0015] In another aspect, the present invention provides a complex concrete reinforcement binding auxiliary method, comprising the following steps:

[0016] S1. Determine the control points and conflict points of the intersecting structures according to the reinforcement scheme of the concrete structure;

[0017] Determine the position of the control point according to the inner diameter and length of the steel bar, and give priority to installing the control point sleeve. Ensure that the control point is no more than 3m away from the first conflict point to ensure that each type of steel bar overcomes the gravity at the top and passes through the control point smoothly and enters the conflict point ahead in turn.

[0018] S2. Install and fix the supporting structure, and adjust the height of the columns to suit the reinforcement scheme;

[0019] S3, install the connecting rod and connect it with the joint and the steering block bolts respectively;

[0020] S4, insert the steel bars and simultaneously complete the overlapping of the intersecting structural steel bars;

[0021] Insert the reinforcement into the casing from one control point, and then insert the reinforcement into the remaining points in turn forward. Pass through all the casings involved in the reinforcement path in turn and keep the reinforcement horizontal and stable before rechecking to ensure that its height is consistent with the existing plan. The insertion and installation of the reinforcement is completed, and the remaining reinforcements are installed in order from bottom to top and from inside to outside, and check that their positions and elevations are correct.

[0022] S5. Install stirrups and complete the binding between the steel bars in sequence;

[0023] Starting from one side, transverse stirrups are installed in sequence to fix the steel bars, and the binding work between the stirrups and the reinforcement is completed simultaneously to form a stable steel cage structure. After the steel bars that have been tied and fixed with the stirrups can maintain a horizontal state, the casing and connecting rod structure are removed in sequence, and the forward operation is realized in a flowing manner, and the stirrup installation and steel binding work of all concrete structures are completed in sequence.

[0024] It overcomes the difficulty of the traditional construction process where stirrups must be installed first and then the steel bars are inserted inward along the inner side of the stirrups, which is easily blocked by the stirrups and other steel bars, making it difficult to ensure that the steel bars are inserted and installed according to the design plan. The device and construction process effectively improve the installation efficiency of the steel bars and stirrups and improve the installation accuracy, reduce labor costs, and realize the simultaneous installation and fixation of multiple layers of steel bars, minimizing construction errors.

[0025] S6. Remove the guide structure and weld the steel bar joints and key areas according to the reinforcement plan;

[0026] After the steel bars and stirrups are tied and all connecting rods and sleeve devices are removed, welding operations are carried out on the steel bar joints and some key areas according to the existing reinforcement plan to ensure that the steel cage forms continuous strength. At this time, all reinforcement installation work in the concrete structure is completed.

[0027] S7. Adjust the supporting structure to the next point and repeat the above steps until all the steel bars are installed, tied and welded.

[0028] Preferably, step S2 specifically includes: determining the installation quantity and installation position of the support structure according to the control points and conflict points, excavating the soil and backfilling and fixing it, adjusting the height of the column through threads, and adjusting the height of the column until the joint is flush with the steel bar.

[0029] After determining the installation location of the support structure, excavate the soil appropriately and backfill it to enhance the stability of the support structure.

[0030] Preferably, the step S3 specifically includes: adjusting the angle of the connecting rod to make the sleeves coaxial, fixing one end of the connecting rod to the joint by bolts, and fixing the other end to the steering block.

[0031] It is installed in sequence from bottom to top and from inside to outside. Through holes are opened on the joints of the supporting structure and the steering blocks of the guide structure, and cavities are opened on both sides of the through holes. The connecting rod can adjust and fix the extension angle according to the construction situation to ensure that the sleeve is located in the same thread.

[0032] The beneficial effects of the present invention are: improved precision and efficiency of steel bar binding, high structural strength and low construction cost. The internal thread in the groove of the deadweight block cooperates with the external thread at the end of the column, so that construction personnel can adjust the height of the column conveniently and accurately, and accurately adapt to the steel bar binding requirements of different heights and different positions. A cavity is opened at the through hole of the joint and the steering block. At the same time, the connecting rod is bolted to the joint and the steering block respectively, and the extension angle of the connecting rod can be adjusted and fixed to ensure that the sleeve is located in the same thread. The steel bar insertion path is guaranteed by multiple sleeves in the same thread, which avoids the collision and obstruction of the steel bar, reduces the difficulty of the side bar insertion, and realizes the synchronous insertion and fixation of multiple steel bars from bottom to top, thereby improving the installation efficiency and accuracy. After determining the installation position of the support structure, the soil is appropriately excavated and backfilled to enhance the stability of the support structure. The support structure can be recycled to complete the installation of the steel bars in the remaining concrete structure in sequence, reducing the construction cost.

[0039] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0040] See also Figures 1 to 5As shown, this embodiment provides a complex concrete reinforcement binding auxiliary device, including a supporting structure and a guiding structure, the supporting structure includes a column, a deadweight block and a plurality of joints, the column and the deadweight block are vertically arranged, and the plurality of joints are welded to the column, the guiding structure includes a steering block, a sleeve and a connecting rod, the steering block is welded to the sleeve, one end of the connecting rod is connected to the joint, and the other end is connected to the steering block.

[0041] The deadweight block is provided with a groove which is adapted to the cross-sectional shape and size of the column. The groove is provided with an internal thread. An end of the column close to the deadweight block is provided with an external thread. The column is threadedly connected to the deadweight block.

[0042] The internal thread in the groove of the deadweight block cooperates with the external thread at the end of the column, so that construction workers can easily and accurately adjust the height of the column to accurately adapt to the needs of steel bar binding at different heights and positions.

[0043] A plurality of joints are evenly distributed along the axial and circumferential directions of the column.

[0044] Through holes with the same shape and size are opened at both ends of the connecting rod, a side of the joint close to the connecting rod, and a side of the steering block close to the connecting rod. The connecting rod is connected with the joint and the steering block by bolts.

[0045] Both sides of the through hole of the joint and the steering block are symmetrically provided with cavities along the tangent direction.

[0046] The through holes of the joint and the steering block are provided with cavities. At the same time, the connecting rod is bolted to the joint and the steering block respectively, and the extension angle of the connecting rod can be adjusted and fixed to ensure that the sleeve is located in the same thread. Multiple sleeves in the same thread ensure the insertion path of the steel bars, avoid collision and obstruction of the steel bars, reduce the difficulty of side reinforcement insertion, and realize the synchronous insertion and fixation of multiple steel bars from bottom to top, which improves the installation efficiency and accuracy.

[0047] The inner diameter of the casing is adapted to the outer diameter of the steel bar.

[0048] This embodiment also provides a complex concrete reinforcement binding auxiliary method, comprising the following steps:

[0049] S1. Determine the control points and conflict points of the intersecting structures according to the reinforcement scheme of the concrete structure;

[0050] Determine the position of the control point according to the inner diameter and length of the steel bar, and give priority to installing the control point sleeve. Ensure that the control point is no more than 3m away from the first conflict point to ensure that each type of steel bar overcomes the gravity at the top and passes through the control point smoothly and enters the conflict point ahead in turn.

[0051] S2. Install and fix the supporting structure, and adjust the height of the columns to suit the reinforcement scheme;

[0052] The support structure is installed according to the specific locations of the control points and conflict points. The inner diameter of the casing and the self-weight structure can be adjusted according to the diameter and length of the reinforcement to ensure that the support structure remains stable.

[0053] The height is adjusted with the help of threads. In this embodiment, the thread structure is set to 10cm, which can be flexibly adjusted within 0-10cm. In actual implementation, appropriate excavation should be carried out according to the soil conditions in the working surface, and backfill should be carried out to ensure that the supporting structure maintains its own stability. After the preparatory work is completed, it should be ensured that the lowest joint is flush with the lowest reinforcement.

[0054] S3, install the connecting rod and connect it with the joint and the steering block bolts respectively;

[0055] It is installed in sequence from bottom to top and from inside to outside. Through holes are opened on the joints of the supporting structure and the steering blocks of the guide structure, and cavities are opened on both sides of the through holes. The connecting rod can adjust and fix the extension angle according to the construction situation to ensure that the sleeve is located in the same thread.

[0056] S4, insert the steel bars and simultaneously complete the overlapping of the intersecting structural steel bars;

[0057] Insert the reinforcement into the casing from one control point, and then insert the reinforcement into the remaining points in turn forward. Pass through all the casings involved in the reinforcement path in turn and keep the reinforcement horizontal and stable before rechecking to ensure that its height is consistent with the existing plan. The insertion and installation of the reinforcement is completed, and the remaining reinforcements are installed in order from bottom to top and from inside to outside, and check that their positions and elevations are correct.

[0058] S5. Install stirrups and complete the binding between the steel bars in sequence;

[0059] Starting from one side, transverse stirrups are installed in sequence to fix the steel bars, and the binding work between the stirrups and the reinforcement is completed simultaneously to form a stable steel cage structure. After the steel bars that have been tied and fixed with the stirrups can maintain a horizontal state, the casing and connecting rod structure are removed in sequence, and the forward operation is realized in a flowing manner, and the stirrup installation and steel binding work of all concrete structures are completed in sequence.

[0060] This embodiment overcomes the difficulty of the traditional construction process that requires the installation of stirrups first and then the insertion of the steel bars inward along the inner side of the stirrups, which is easily obstructed by the stirrups and other steel bars, making it difficult to ensure that the steel bars are inserted and installed according to the design plan. The device and construction process effectively improve the installation efficiency of the steel bars and stirrups and the installation accuracy, reduce labor costs, and realize the simultaneous installation and fixation of multiple layers of steel bars, minimizing construction errors.

[0061] S6. Remove the guide structure and weld the steel bar joints and key areas according to the reinforcement plan;

[0062] After the steel bars and stirrups are tied and all connecting rods and sleeve devices are removed, welding operations are carried out on the steel bar joints and some key areas according to the existing reinforcement plan to ensure that the steel cage forms continuous strength. At this time, all reinforcement installation work in the concrete structure is completed.

[0063] S7. Adjust the supporting structure to the next point and repeat the above steps until all the steel bars are installed, tied and welded.

[0064] By setting a support structure on one side of the concrete structure and using connecting rods and sleeves to determine the location of the steel bar layout, the linear channel formed by multiple sleeves can greatly reduce the difficulty of side reinforcement insertion and realize the synchronous insertion and fixation of multiple steel bars from bottom to top. After the side reinforcement is installed, the stirrups are installed and tied, and then the steel cage in the concrete structure is tied. At the intersection of the concrete structure, the steel bars in two or more structures can be synchronously inserted, fixed and tied, reducing the difficulty and cost of later welding construction and improving the accuracy of steel bar layout and welding. At the same time, the support structure can be recycled to complete the installation of the remaining steel bars in the concrete structure in turn, effectively reducing the construction cost and achieving cost reduction, quality improvement and efficiency increase in steel bar tying work.
