Description

Technical Field

[0001] The utility model relates to the technical field of building main structure construction, and more specifically to the technical field of a steel bar positioning device for a main structure column. Background Art

[0002] During the construction of the main structure, since the length of the vertical steel bars of the column is generally not less than the height of one floor, the steel bars are prone to bending and deformation under the action of gravity, especially in the core area where the beams and columns meet. The steel bars of the beams and columns in the core area are staggered, and the addition of stirrups causes the vertical steel bars of the column to deviate after leaving the floor surface. When the main steel bars with deviations are continued to be constructed on the upper layer, the deviation of the steel bars continues to be transmitted, resulting in the main vertical steel bar protective layer of the upper layer being unqualified. When the steel bars are scanned later, the protective layer does not meet the requirements of the specifications, resulting in quality accidents. How to ensure the accurate positioning of the main vertical steel bars and avoid the deviation of the steel bar protective layer, which affects the construction quality of the main structure, has become an urgent problem to be solved. Utility Model Content

[0003] The purpose of the utility model is to solve the above technical problems and provide a steel bar positioning device for a main structure column, which helps to ensure the accuracy of steel bar positioning in the cast-in-place area of ​​the column structure and avoid steel bar deviation, which may lead to unqualified steel bar protection layer scanning in the later stage.

[0004] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0005] This embodiment provides a steel bar positioning device for a main structure column, including a longitudinal single-group fixing device and a transverse single-group fixing device superimposed on the longitudinal single-group fixing device, and the longitudinal single-group fixing device and the transverse single-group fixing device are arranged orthogonally.

[0006] Specifically, because the steel bars of a single column structure are mainly divided into two groups, longitudinal and transverse, this steel bar fixing device is divided into a longitudinal single group fixing device and a transverse single group fixing device in order to realize the function of positioning the steel bars around the column.

[0007] In one embodiment, the longitudinal single group of fixing devices and the transverse single group of fixing devices have the same structure.

[0008] In one embodiment, the longitudinal single-group fixing device and the transverse single-group fixing device each include two mutually parallel containing members for containing vertical steel bars, and the two containing members are locked by screw assemblies on both sides.

[0009] In one embodiment, each screw assembly includes a full-length screw and locking assemblies arranged on both sides of the full-length screw, and the locking assemblies include a butterfly nut and a nut fixing buckle.

[0010] Specifically, the butterfly nut is located at the outer end of the full-length screw, and cooperates with the nut fixing buckle to fix the steel bars between the main frames within the designed protective layer; the nut fixing buckle is located on the full-length screw and is used in conjunction with the butterfly nut to achieve the positioning and fixation of the vertical steel bars.

[0011] In one embodiment, the through-length screw is a circular through-length screw with a threaded opening, and the length of the through-length screw is greater than the distance between the outer walls of the two containing components.

[0012] Specifically, the through-length screw is a round, full-length screw with a threaded mouth, and its length can be slightly longer than the outer diameter of the main body of the fixed structure. The through-length screw cooperates with the butterfly nut and the nut fixing buckle, and the fixing grooves on the main frame and the sub-frame are used to fix the position of the unidirectional steel bars to prevent the steel bars from being displaced.

[0013] In one embodiment, the accommodating component includes a main frame and a sub-frame matched with the main frame, a accommodating groove for accommodating vertical steel bars is formed between the main frame and the corresponding sub-frame, and the main frame and the corresponding sub-frame are locked by a matching bolt assembly.

[0014] Specifically, the main frame is an important part of the steel bar positioning device, located on the outside of the vertical column steel bar, and cooperates with the auxiliary frame, full-length screws and matching bolts to achieve the positioning and fixation of the column vertical steel bar. The auxiliary frame is an important part of the steel bar positioning device, located on the inside of the vertical column steel bar, and cooperates with the main frame, full-length screws and matching bolts to achieve the positioning and fixation of the column vertical steel bar.

[0015] The vertical steel bars are located between the main frame and the sub-frame. The quantity and number of the steel bars are determined according to the design. They are an important part of the main structure and also need to be fixed with this steel bar to adjust their position, ensure the thickness of the steel bar protective layer, and ensure that the steel bars do not deviate and affect the scanning quality of the steel bars in the later stage.

[0016] In one embodiment, both sides of the main frame and the auxiliary frame are respectively provided with fixing grooves for installing the screw rod assembly.

[0017] In one embodiment, an elliptical groove for installing a matching bolt assembly is provided in the middle of the main frame and the auxiliary frame.

[0018] Specifically, the fixing groove is located at both ends of the single main frame and the auxiliary frame, presenting a semi-open elliptical groove, mainly to provide installation space for the full-length screw. The elliptical groove is located in the middle of the single main frame and the auxiliary frame, presenting an elliptical open groove, mainly to provide installation space for the matching bolts.

[0019] In one embodiment, both ends of the main frame are provided with fixing buckle grooves for use with corresponding nut fixing buckles.

[0020] Specifically, the fixing buckle grooves are located at both ends of the main frame and are used in conjunction with the nut fixing buckles to ensure that the position of the butterfly nut fixed on the main frame does not deviate, thereby affecting the steel bar positioning effect.

[0021] In one embodiment, the matching bolt is a single-head bolt, which is used in combination with a nut.

[0022] Specifically, the elliptical grooves in the middle of the main frame and the auxiliary frame are used to position and fix the vertical steel bars. This structural setting prevents the column steel bars from leaning toward the inside of the main body and affecting the thickness of the steel bar protective layer.

[0023] Generally speaking, the longitudinal single-group fixing device is composed of a longitudinal main frame, a sub-frame, a full-length screw, a butterfly nut, a nut fixing buckle, a fixing groove, an elliptical groove, a fixing buckle groove, matching bolts, vertical steel bars, etc., to achieve the fixation and positioning of the longitudinal steel bars of the column.

[0024] The horizontal single-group fixing device is composed of a horizontal main frame, a sub-frame, a full-length screw, a butterfly nut, a nut fixing buckle, a fixing groove, an elliptical groove, a fixing buckle groove, matching bolts, vertical steel bars, etc., to achieve the fixation and positioning of the horizontal steel bars of the column.

It can be used for cast-in-place main structures and can also be used for positioning construction of prefabricated vertical steel bars. It has a wide range of applications and good positioning effects.

[0027] 2. This steel bar device is used to position the vertical steel bars to avoid deviation, which effectively solves the problem of unqualified steel bar protection layer scanning in the later stage due to deviation in the positioning of the main steel bars, which often occurs at the construction site. It ensures the construction quality of the vertical steel bars and avoids the occurrence of quality accidents. BRIEF DESCRIPTION OF THE DRAWINGS
