Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a steel structure rapid adjustment device. Background Art

[0002] In modern construction projects, concrete columns serve as the primary vertical load-bearing components, and their construction quality is directly related to the safety and durability of the overall structure. According to the Code for Design of Concrete Structures (GB 50010-2010), the positional deviation of vertical reinforcement in concrete columns must not exceed 5mm; otherwise, the structure's load-bearing capacity will be severely impacted.

[0003] However, during the concrete pouring process, especially when vibrating the concrete to compact it, the reserved longitudinal reinforcement at the top of the concrete column is prone to shifting due to the vibration force. This shifting of the reinforcement can reduce the bond between the reinforcement and the concrete, thus affecting the overall performance of the reinforced concrete and even posing a safety hazard to the structure.

[0004] At present, the traditional method of steel bar positioning mainly adopts temporary brackets or binding fixation, but these methods have the following problems:

[0005] 1. Traditional fixing methods use wire tying or welding temporary brackets, which have low adjustment accuracy and often fail to meet regulatory requirements;

[0006] 2. Most existing positioning devices are disposable and cannot adapt to the positioning requirements of steel bars of different diameters, resulting in material waste;

[0007] 3. During the concrete vibration process, the steel bars are easily displaced by the vibration force, and the average displacement can reach 8-12mm;

[0008] 4. For special-shaped columns or columns with variable cross-sections, the existing positioning devices have poor adaptability and low installation efficiency.

[0009] A search revealed that existing technologies, such as Patent No. CN201920358212.3, which discloses a steel bar positioning device, suffer from problems such as a limited adjustment range and loose fixation. Patent No. CN202010584521.8, while offering improved adjustment capabilities, suffers from a complex structure and inconvenient operation. Therefore, there is an urgent need to develop a new type of rapid adjustment device for steel structures to address these technical issues. Summary of the Invention

[0038] See also Figure 1As shown, the present invention is a steel structure quick adjustment device, including a clamp frame 100 and a steel bar adjustment clamp mechanism 200 arranged in an array in the circumferential direction of the clamp frame 100, and the steel bar adjustment clamp mechanism 200 is provided with a steel bar positioning clamp head 201 for limiting the movement of vertical steel bars; wherein, the limiting position between the steel bar positioning clamp head 201 and the clamp frame 100 can be adjusted by the steel bar adjustment clamp mechanism 200.

[0039] During the use of the adjustment device of the present application, the main designs include a clamp frame 100 and a steel bar adjustment clamp mechanism 200. The steel bar adjustment clamp mechanism 200 on the clamp frame 100 can be pre-adjusted according to the positioning position of the steel mesh skeleton on the concrete column, so that the steel bar positioning clamp head 201 meets the vertical steel bar restricted passing position, so as to avoid the longitudinal steel bars reserved at the top of the concrete column from being easily offset during the vibration process. The restricted positioning steel bars can ensure the quality of the reinforced concrete, thereby improving the quality and service life of the structure, and making it safe and stable.

[0040] In this specific embodiment, Figure 2 As shown, the steel bar adjustment clamp mechanism 200 is perpendicular to the single-sided plate 101 of the clamp frame 100 and is movable in the vertical direction and / or length direction of the single-sided plate 101; the clamp frame 100 is the main component supported by the steel bar adjustment clamp mechanism 200. When the steel bar adjustment clamp mechanism 200 is arranged in an array in its circumferential direction, it is necessary to adjust the position of the steel bar positioning clamp head 201 according to the actual vertical steel bar position. When the steel bar adjustment clamp mechanism 200 moves in the vertical direction of the single-sided plate 101, it can meet the movement adjustment of the restricted position between the steel bar positioning clamp head 201 and the clamp frame 100; when the steel bar adjustment clamp mechanism 200 moves in the length direction of the single-sided plate 101, it can meet the movement adjustment of the restricted position of the adjacent vertical steel bars; during specific operation, the steel bar adjustment clamp mechanism 200 is moved and adjusted in the vertical direction and length direction of the single-sided plate 101 according to the actual vertical steel mesh skeleton position.

[0041] In this specific embodiment, Figure 2 and Figure 3 As shown, the steel bar adjustment clamp mechanism 200 includes a ball screw 202 that is vertically inserted on the single-sided plate 101, one end of the ball screw is fixedly connected to the steel bar positioning clamp head 201, and the thread on the ball screw is connected to the screw seat 203 and the screw locking block 205. The screw seat is fixedly connected to one side plate surface of the single-sided plate 101, and the screw locking block is abutted and locked on the other side plate surface of the single-sided plate 101; an L-shaped baffle 204 is movably sleeved on the ball screw, and the L-shaped baffle 204 is clamped between the screw locking block and the single-sided plate 101; the end of the ball screw is rotatably connected to the bearing seat 206 through a rolling bearing 207, and the bearing seat 206 is used to abut and stabilize the steel bar positioning clamp head 201.

[0042] During the design process of the steel bar adjustment clamp mechanism 200 in the present application, the operator can hold the steel bar positioning clamp head 201 and rotate it to make the threaded connection assembly composed of the ball screw, the screw seat 203, the L-shaped baffle 204 and the screw lock block 205 cooperate, so that the steel bar positioning clamp head 201 can be moved and adjusted to the restricted position between the clamp frame 100. The adjustment is fast and convenient, which helps to greatly improve construction efficiency.

[0043] In this specific embodiment, Figure 4 As shown, the steel bar positioning clamp head 201 includes a detachably connected positioning clamp piece 1 208 and a positioning clamp piece 2 209, and a limiting through hole with a vertical steel bar is formed between the positioning clamp piece 1 208 and the positioning clamp piece 2 209; when the positioning clamp piece 1 208 and the positioning clamp piece 2 209 are fixed together, one end of the positioning clamp piece 1 208 is connected to the positioning clamp piece 2 209 by a bolt, and the other end is pinned and fixed to the positioning clamp piece 1 208 and the positioning clamp piece 2 209 together by a pin 210; the steel bar positioning clamp head 201 in this application is detachably connected by the positioning clamp piece 1 208 and the positioning clamp piece 2 209 When the positioning clip 1 208 and the positioning clip 2 209 are assembled and used as a whole, the restricted through hole enclosed by them can position the vertical steel bars to avoid deviation; when the positioning clip 1 208 and the positioning clip 2 209 are disassembled and used in circulation, the pin 210 is pulled out and the threaded connection between the positioning clip 1 208 and the positioning clip 2 209 is released, so that the steel bar positioning clamp head 201 can be recycled; it should be understood that the steel bar positioning clamp head 201 is provided with a variety of specifications, and the steel bar positioning clamp head 201 of the corresponding specification can be selected according to the vertical steel bar diameter of different concrete columns.

[0044] In this specific embodiment, Figure 5 As shown, the clamp frame 100 is a polygonal structure frame surrounded by multiple single-sided plates 101, and multiple steel bar adjustment clamp mechanisms 200 are arranged in an array on each single-sided plate 101; each single-sided plate 101 is provided with a full-length waist hole 102, and the ball screw 202 on the steel bar adjustment clamp mechanism 200 can be movably inserted into the full-length waist hole 102; multiple positioning holes 103 are arranged in an array on the single-sided plate 101 and on the upper and lower sides of the full-length waist hole 102, and the positioning holes 103 are used to connect the screw seat on the steel bar adjustment clamp mechanism 200 by bolts.

[0045] When the clamp frame design in this application is used, the specifications of the concrete columns are different, and it can be a quadrilateral structure or other multi-sided structure. Each single-sided plate 101 on the clamp frame 100 can be arranged in an array with multiple steel bar adjustment clamp mechanisms 200 to meet the positioning needs of the steel mesh skeleton in concrete columns of different specifications, and has a wide range of applications.

[0046] In this specific embodiment, the method of using the steel structure rapid adjustment device of the present application is as follows:

[0047] Step 1: Adjust the size and shape of the fixture frame 100 according to the size of the concrete column and the arrangement of the reinforcement bars.

[0048] Step 2: Move the steel bar adjusting fixture mechanism 200 along the length direction and vertical direction of the single-sided plate 101 so that the steel bar positioning clamp head 201 is aligned with the vertical steel bar.

[0049] Step 3: Rotate the ball screw 202 to adjust the position of the steel bar positioning clamping portion 201 and lock it.

[0050] Step 4: Insert the vertical steel bars into the through holes formed by the first positioning clip 208 and the second positioning clip 209 to complete the fixation.

[0051] Example 1

[0052] The steel structure rapid adjustment device of the present application utilizes steel bars within a quadrilateral concrete column for positioning.

[0053] The concrete columns of a high-rise building project are quadrilateral structures with multiple vertical steel bars arranged inside. To ensure the construction quality of the concrete columns, a fast and accurate steel bar positioning device is required to locate and fix the vertical steel bars.

[0054] According to the size of the quadrilateral concrete column and the arrangement of the reinforcement bars, the size and shape of the clamp frame 100 are adjusted so that it can fit closely around the sides of the concrete column.

[0055] On each single-sided plate 101 of the clamp frame 100, a plurality of steel bar adjustment clamp mechanisms 200 are arranged in an array according to the position of the vertical steel bars. By moving the steel bar adjustment clamp mechanism 200, the steel bar positioning clamp head 201 is aligned with the vertical steel bar.

[0056] The ball screw 202 is rotated to adjust the distance between the steel bar positioning clamping portion 201 and the clamp frame 100 so that the steel bar positioning clamping portion 201 can tightly clamp the vertical steel bar.

[0057] Insert the vertical steel bars one by one into the limiting through holes of the corresponding steel bar positioning clamp parts 201, and fix the positioning clamp piece 1 208 and the positioning clamp piece 2 209 together by bolts and pins to ensure the stability of the steel bar positioning.

[0058] After all vertical steel bars are positioned and fixed, the clamping condition of each steel bar positioning clamping portion 201 is checked to ensure that there is no looseness or deviation.

[0059] After the steel bars are positioned and fixed, the concrete pouring operation is carried out. During the pouring process, a vibrating rod is used to vibrate and compact the concrete.

[0060] Due to the firm clamping effect of the steel bar positioning clamping portion 201, the vertical steel bars are effectively prevented from deflecting during the vibration process.

[0061] After the concrete pouring is completed and the concrete reaches a certain strength, the bolts and pins on the steel bar positioning clamping portion 201 are removed, and the steel bar positioning clamping portion 201 is removed from the end of the ball screw 202 .

[0062] The steel bar adjustment clamp mechanism 200 and the clamp frame 100 and other components are disassembled, cleaned and maintained, and then properly stored for next use.

[0063] Example 2

[0064] The steel structure rapid adjustment device of the present application is used to position the steel bars in special-shaped concrete columns.

[0065] The concrete columns of an industrial plant project are irregularly shaped, with multiple vertical rebars of varying diameters and orientations arranged within them. To ensure the quality of the concrete columns, a positioning device was required that could accommodate these irregular structures and rebars of varying diameters.

[0066] The specific construction steps are the same as those in Example 1. The difference is that for the construction of special-shaped columns, the frame shape is adjusted by increasing or decreasing the number of single-side plates, and steel bar positioning clamps 201 with different inner diameters are configured to achieve multi-specification adaptation.

[0067] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
