Technical Field
[0001] The present invention relates to the technical field of building construction, and more particularly to a method for positioning and constructing reinforced concrete walls and vertical column reinforcement bars. Background Art
[0002] With the booming development of the modern construction industry, the construction techniques of bare concrete and direct puttying of concrete for decoration without plastering have gradually become mainstream. This construction method demonstrates significant advantages in saving manpower and material resources, improving work efficiency, and protecting the environment. At the same time, with the development of the construction industry, the requirements for the quality and appearance of building structures are constantly increasing. In the construction of frame shear wall structures, steel bars serve as the building's skeleton. The accuracy of their positioning directly affects the structure's load-bearing capacity and stability. Therefore, the steel bars require precise positioning during construction.
[0003] However, existing technologies often rely on manual experience and simple auxiliary tools to tie steel bars, making it difficult to accurately control the position of the steel bars. Due to the lack of specially designed components such as trapezoidal bars and positioning fixtures, the spacing of the steel bars in the horizontal and vertical directions is prone to deviation, and stability cannot be guaranteed. When faced with complex frame shear wall structures, it is even more difficult to cope with the positioning problems of small-diameter steel bars and multi-layer steel mesh. As a result, the displacement and deformation of the steel bars occur frequently, affecting the construction quality of the steel bar project and posing a potential threat to the safety performance of the entire building structure. It increases the cost and risk of subsequent maintenance and reinforcement, prolongs the construction period, and reduces construction efficiency. In view of this, we propose a construction method for positioning steel bars for reinforced concrete walls and vertical columns. Summary of the Invention

[0032] Example 1, as Figures 1 to 5 As shown, the present invention relates to a method for positioning and constructing reinforced concrete walls and vertical column reinforcement bars, comprising the following steps:
[0033] S1: Shear wall reinforcement binding, shear wall construction preparation, correction of structural reinforcement position, setting of horizontal control line, installation of vertical trapezoidal reinforcement, installation of horizontal trapezoidal reinforcement, correction of trapezoidal reinforcement horizontal and vertical, vertical and horizontal reinforcement binding, binding of tension bars, binding of support bars, binding of protective layer pads.
[0034] The specific preparations for shear wall construction and frame column construction in steps S1 and S2 are as follows:
[0035] The vertical trapezoidal reinforcement of the shear wall is made of steel bars with a diameter one grade larger than the wall reinforcement. The horizontal reinforcement of the ladder rungs is made of Φ12 round steel, which is divided into two length specifications: wall thickness minus protective layer and wall thickness minus 2mm. The vertical positioning trapezoidal reinforcement is made of steel bars one grade higher than the wall reinforcement and tied to the wall reinforcement. The spacing of the vertical trapezoidal reinforcement is generally 2000mm and there are no less than two per wall height; the longitudinal reinforcement of the horizontal trapezoidal reinforcement is made of Φ12-14 steel bars, the length of which is controlled to be the wall length and not more than 3000mm, and the horizontal reinforcement of the ladder rungs is Φ1 2 round steels, length is the wall thickness minus 30mm, and the distance is the same as the spacing of the wall vertical reinforcement; the internal support bars are divided into single control and double control. The support bars are made of Φ10-12 round steel according to the wall thickness, and the length is the wall thickness minus 2mm. The horizontal reinforcement stops of the wall are made of Φ8 round steel, with a length of 20mm. The ends are ground into a 3mm high frustum and painted with two coats of anti-rust paint; the positioning fixtures of the frame columns are made of Φ14-16 round steel according to the size of the column section. The remaining longitudinal reinforcement stops are made of Φ10 round steel, and the stop length is 30mm.
[0036] Construction Preparation: Accurately draw drawings of vertical trapezoidal bars, horizontal trapezoidal bars, and double "F"-shaped internal bracing bars according to the drawings and specifications. After review by the technical department, these drawings must be submitted to the fabrication plant for production. The fabrication plant must produce molds based on the drawing dimensions. Large-scale production can only begin after inspection, acceptance, and test welding. Since vertical trapezoidal bars are not reusable, they are constructed from rebar one diameter grade larger than the wall's vertical bars to conserve materials. The rung cross bars are available in two lengths, one to limit the spacing between horizontal bars and the other to control the thickness of the steel mesh and wall. Horizontal trapezoidal bars are reusable, and the dimensions of their longitudinal and rung cross bars are determined based on the wall length and thickness. Double "F"-shaped internal bracing bars are divided into single-control and double-control types based on their function. The support bars and stop points are sized to suit the wall thickness and rebar specifications, and are properly treated to prevent rust. Concrete residue should be removed from the reserved reinforcement, the inner and outer edges of the shear wall should be marked and inspected, and the scaffolding or operating platform should be erected.
[0037] Correct the vertical reinforcement of the structure: According to the inner and outer edges of the wall, correct the reinforcement with excessive protective layer deviation and reinforcement spacing deviation, and use the 1:6 bending method to adjust the reinforcement position to ensure that the reinforcement position meets the design requirements, laying the foundation for subsequent reinforcement binding.
[0038] Horizontal control line: Use a level to accurately measure the floor +500mm line and clearly mark it on the vertical steel bars as the reference line for the subsequent steel bar binding height to ensure the horizontality and verticality of the steel bar binding.
[0039] Install vertical trapezoidal reinforcement: temporarily fix the vertical trapezoidal reinforcement on the steel bars thrown out of the lower wall, use the wire to level it, ensure the first ladder cross reinforcement is in a reasonable position, and temporarily fix it with horizontal reinforcement, set it at the specified spacing, provide an accurate positioning frame for the vertical reinforcement, and ensure uniform spacing of the vertical reinforcement.
[0040] Vertical trapezoidal reinforcement must undergo strict pre-inspection before use. Before binding, the vertical trapezoidal reinforcement of the same wall must be leveled with a line and firmly tied to the wall's stub reinforcement to ensure the accuracy of the horizontal reinforcement spacing and prevent the deviation of the reinforcement spacing caused by the installation of the trapezoidal reinforcement, thereby ensuring the stability of the entire reinforcement structure system.
[0041] Install horizontal trapezoidal reinforcement: Install horizontal trapezoidal reinforcement at the designated position, connect it to the positioning fixtures such as hidden columns, and avoid the reinforcement overlap area to provide stable support and positioning for the horizontal reinforcement binding, and ensure the accurate position of the horizontal reinforcement.
[0042] Correct the trapezoidal reinforcement: Based on the floor +500mm line, use tools such as plumb lines to correct the horizontal and vertical degree of the trapezoidal reinforcement to ensure that it is horizontal and vertical, and use scaffolding or temporary supports to fix it to ensure that the elevation of the trapezoidal reinforcement on the same floor is uniform, creating good conditions for steel bar binding.
[0043] Binding of vertical and horizontal reinforcement: Fix the reinforcement tightly to the trapezoidal reinforcement, first extend the vertical reinforcement, and then bind the horizontal reinforcement one by one, ensuring that the reinforcement is on the same side of the ladder reinforcement and close to the trapezoidal reinforcement, so that the reinforcement is firmly tied and the position is accurate, in line with the design and specification requirements.
[0044] Tie the reinforcement: Tie the reinforcement in a plum blossom-shaped arrangement, strictly control the spacing between the reinforcements to no more than 600mm, ensure that the reinforcement hooks the vertical and horizontal distribution bars at the same time, and when there are more than two rows of distribution bars on the wall, ensure that the reinforcement is firmly connected to each row of distribution bars to enhance the integrity and stability of the steel mesh.
[0045] Binding support reinforcement: Support reinforcement is set in the middle of the wall with a spacing of no more than 600mm. The support reinforcement replaces part of the pads and tension reinforcement functions. Anti-rust treatment is done on both ends to prevent the wall formwork from moving inward and ensure uniform thickness of the steel bar protective layer.
[0046] Binding protective layer pads: Select plastic pads of appropriate specifications, arrange them in a plum blossom shape and clamp them on the main reinforcement with a spacing of no more than 600mm to ensure that the thickness of the main reinforcement protective layer meets the design requirements, prevent steel bar corrosion, and improve the durability of the concrete structure.
[0047] S2: Binding of frame column reinforcement, preparation for frame column construction, correction of structural reinforcement position, installation of vertical trapezoidal reinforcement, positioning of stirrups, setting of reinforcement positioning fixtures, binding of stirrups, and binding of protective layer pads.
[0048] Construction Preparation: Fabricate positioning fixtures and select appropriate rebar to create frames and stop points based on column cross-sections, ensuring accurate and reusable positioning fixtures. Also, plan axis lines and column edges, conduct preliminary inspections, and set up operating platforms or scaffolding to provide a favorable working environment for rebar tying.
[0049] Correct the position of the vertical reinforcement of the structure: clean the concrete residue on the reserved column reinforcement, correct the position of the vertical reinforcement according to the column edge line, and adjust it to 1:6 when the deviation is large to ensure the accurate position of the column vertical reinforcement and make the column evenly stressed.
[0050] Vertical reinforcement connection: Ensure that the vertical reinforcement connection form complies with the design and specification requirements and passes the pre-inspection acceptance to ensure the strength and stability of the reinforcement connection and meet the structural load-bearing requirements.
[0051] Stirrups in place: Calculate the number of stirrups according to the requirements of the drawings, put the stirrups on the protruding steel bars of the lower layer, and pay attention to the arrangement of the openings along the four corners of the column to prepare for the subsequent stirrup binding and ensure that the stirrups are installed in the correct position.
[0052] Set up the steel bar positioning fixture: Install the positioning fixture at the appropriate position on the top of the column to accurately place the vertical steel bars into the blocking point, effectively limit the position of the main bars, prevent the steel bars from shifting, and ensure the stability of the column steel bar skeleton.
[0053] Stirrup binding: Draw the stirrup spacing line on the vertical steel bars, and tie the stirrups from top to bottom along the line. Use loop buckles at the corners and figure-eight buckles in the middle, with the binding wire facing the inside of the component, so that the stirrups are tightly connected to the main bars to enhance the seismic performance of the column.
[0054] Binding protective layer pads: Select concrete pads of appropriate specifications and clamp them on the main reinforcement with a vertical spacing of 1000mm to ensure the thickness of the main reinforcement protective layer, prevent the steel bars from being exposed, and improve the durability of the column concrete structure.
[0055] The wall distribution reinforcement is uniformly tied with standardized "figure eight buckles", the main reinforcement at the four corners of the concealed column is tied with "pocket buckles" or "cross buckles", and the main reinforcement in the middle is tied with "figure eight buckles", and all binding wire heads must face the interior of the concrete to avoid adverse effects on the performance of the concrete structure caused by exposed wire heads; the steel bar joints are strictly tied with three buckles according to regulations, that is, one buckle is required at 50mm from the end, and another buckle is tied in the middle to ensure that the steel bar connection is firm and reliable and effectively transfers stress.
[0056] Accurately determine the position of the starting stirrups, ensure that the horizontal starting reinforcement of the wall is 50mm, and adjust the starting stirrups of the hidden column appropriately downward to 25-30mm, to ensure that the steel bar layout meets the design requirements, enhance the integrity of the structure, and enable the steel bars to better coordinate the force during the concrete pouring process to maintain structural stability.
[0057] The processing dimensions of the positioning ribs and trapezoidal ribs must be accurate and correct. After removal, they must be cleaned and calibrated in time. Reuse of those with large deviations is strictly prohibited to ensure the reliability and reusability of the positioning components and provide stable quality assurance for multiple construction cycles.
[0058] The type and quality of steel bars, the brand and performance of welding rods and flux, and the steel bars used must fully comply with the design requirements and relevant standards. Strict control must be exercised in every link from raw material procurement and inspection to use to ensure the quality of the steel bar project and prevent structural safety hazards caused by material problems.
[0059] The surface of the steel bars must be kept clean. For steel bars with granular and flaky old rust and still have pitting after rust removal, it is strictly forbidden to use them according to the original specifications to prevent the corrosion of the steel bars from affecting the structural strength, ensure that the bonding force between the steel bars and concrete is not damaged, and maintain the bearing capacity of the structure.
[0060] The specifications, shapes, dimensions, quantity, spacing, anchorage length, joint position and other parameters of the steel bars must strictly comply with the design requirements and construction specifications to ensure that the steel bars can exert their due mechanical properties in the concrete structure, so that the structure is safe and reliable under the design load and to avoid structural damage caused by unreasonable steel bar arrangement.
[0061] Control the number of missing or loose ties in the tied steel bars to no more than 5% of the total number of ties, and do not concentrate them, to ensure the firmness of the steel bar binding, prevent the steel bars from loosening during construction and use, ensure that the steel bar skeleton can remain stable during concrete pouring, and avoid affecting the structural stress performance due to steel bar displacement.
[0062] The length deviation of the limiting reinforcement is controlled within ±3mm, and the welding deviation of the positioning reinforcement and the limiting reinforcement is controlled within ±3mm, ensuring the accuracy of the positioning reinforcement and the limiting reinforcement, effectively limiting the position of the reinforcement, ensuring the accuracy of the position of the reinforcement during the construction process, and preventing uneven structural force caused by positioning deviation.
[0063] The raw material for the locating bars is primarily short rebar found on-site, requiring no pollution or corrosion. E4303 welding rods are used. Marble or concrete spacers are used as required for the protective layer, and their dimensions must meet the concrete cover requirements. The dimensions of the trapezoidal locating bars and locating frames must strictly comply with the rebar spacing requirements specified in the drawings to ensure accurate positioning. Equipment includes AC welding machines for welding locating bars and other components; abrasive cutters for cutting rebar; rebar hooks for tying rebar; steel tape measures for measuring dimensions; scaffolding for providing a construction platform; trapezoidal rebar molds for processing the trapezoidal rebar; and rebar cutters for cutting rebar. These tools and equipment work in concert to ensure smooth construction.
