Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a positioning device and method for reinforcing bars of a frame column foundation without welding. Background Art

[0002] In building engineering, when fixing column insert bars in an independent concrete column foundation, it is generally achieved by spot welding the erection bars and the main bars. One end is spot welded to the foundation slab bars, and the other end is spot welded to connect the corner insert bars of the column to form an integral body with unified force.

[0003] When spot welding the reinforcing bars, after placing the erection bars in the established position, they and the overlapping reinforcing bars are welded and fixed. If the position of the column bars is not accurately controlled, it will lead to an increase in the rectification construction cost and material waste after the column bars are welded and fixed. If the column foundation insert bars with large deviations are not rectified, it will lead to the deviation of the axial position of the column bars from the designed position after concrete construction, affecting the structural safety.

[0004] Moreover, the quality of spot welding the reinforcing bars directly affects the stability of the column foundation insert bars and damages the column bars. If the spot welding is not firm, the column insert bars will overturn or shift, affecting the structural safety of the column; if the spot welding is excessive, the main bars of the foundation will be damaged.

[0005] Therefore, there is an urgent need for a positioning device and method for reinforcing bars of a frame column foundation without welding to solve the above technical problems. Summary of the Invention

All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope protected by the present invention.

[0034] Figure 1 is the structural schematic diagram of this embodiment, Figure 2 is the independent foundation plan view of this embodiment, as Figure 1 and Figure 2 shown, this embodiment provides a positioning device for the reinforcement of a frame column foundation without welding, including the main bars 1 of the bottom plate, the support structure 2 and the main bars 3 of the column.

[0035] Figure 3 is the structural schematic diagram of the support structure in this embodiment, as Figure 3 shown, the support structure 2 includes a top connection section 23 and a first support body 21 and a second support body 22 arranged on both sides of the top connection section 23. The first support body 21 and the second support body 22 in this embodiment are symmetrically arranged along the center of the top connection section 23. During construction, the support structure 2 will be positioned at the predetermined position by cross binding to prevent the column bars from being disturbed by construction factors.

[0036] Among them, the first support body 21 includes a first bottom connection section 211 and a first middle connection section 212. The two ends of the first middle connection section 212 are respectively connected to one end of the first bottom connection section 211 and the top connection section 23, and the first bottom connection section 211 is bound and connected to the main bars 1 of the bottom plate.

[0037] The second support body 22 includes a second bottom connection section 221 and a second middle connection section 222. The two ends of the second middle connection section 222 are respectively connected to the other end of the second bottom connection section 221 and the top connection section 23; the second bottom connection section 221 is bound and connected to the main bars 1 of the bottom plate.

[0038] The main bars 3 of the column are respectively bound and fixed to the top connection section 23 of the support structure 2 and the main bars 1 of the bottom plate.

[0039] This frame column foundation steel bar non-welding positioning device installs a support structure 2 with cross-binding positioning at the position of the inserted steel bars of the independent column foundation, binds and fixes the upper end of the support structure 2 to the column main steel bars 3, and binds and fixes the lower end to the main steel bars 1 of the column foundation floor slab. In this way, the axis positioning is easy to rectify and welding is avoided. And through the support structure 2 with cross-binding positioning at a predetermined position, it prevents the construction factors from disturbing the column steel bars. While ensuring firm installation, the completed surface of the foundation pouring is easier to control. The support structure 2 is convenient to install, firmly fixed, accurately positioned, with low rectification cost for workers and no waste of materials.

[0040] As an optional implementation manner, it further includes stirrups 4. The stirrups 4 are arranged outside the column main steel bars 3 and are bound and fixed to the column main steel bars 3.

[0041] As an optional implementation manner, the first middle connection section 212 is inclined.

It can be understood that when the angle is less than 120° or greater than 135°, the support reliability is reduced and cannot meet the use requirements.

[0046] The lengths of the first bottom connection section 211 and the second bottom connection section 221 in this embodiment are both 20 cm - 25 cm.

[0047] The length of the top connection section 23 in this embodiment is the same width as the columnar area enclosed by the column main steel bars 3. And the center of the top connection section 23 is collinear with the axis of the columnar area.

[0053] S4: After the supporting structure 2 and the bottom plate main reinforcement 1 are tied and fixed, the column main reinforcement 3 is tied and fixed together with the supporting structure 2 and the bottom plate main reinforcement 1;

[0054] In this embodiment, after the support structure 2 and the bottom plate main reinforcement 1 are tied in a cross manner, the column main reinforcement 3 and the stirrups 4 at the lower end of the column are tied and fixed together with the support structure 2 and the bottom plate main reinforcement 1 according to the axis positioning.

[0055] S5: After the main reinforcement 3 of the column is tied and fixed, it is rechecked and adjusted according to the position of the column axis and the stability is checked. After it meets the requirements, concrete is poured.
