Description

Technical Field

[0001] This utility model relates to a high-precision assembled column reinforcement positioning tool, belonging to the field of concrete structure reinforcement engineering construction in building engineering. Specifically, it is used to fix the position of the main reinforcement of the column more accurately and flexibly, and prevent the column reinforcement from deviating during the concrete pouring process. Background Technology

[0002] In construction engineering, concrete columns mainly bear vertical loads, among which steel bars, as the main load-bearing components, bear most of the tensile stress. Therefore, the position of the steel bars and the accuracy of the steel bar protective layer are particularly important. During the concrete pouring process, the main reinforcement bars of the column that extend beyond the slab surface do not have reliable fixing measures. Under the impact of concrete and contact with the pump pipe wall, the column reinforcement bars are easily misaligned. After the concrete structure is formed, the reinforcement bars cannot be adjusted to the design position without damage, thus affecting the structural safety.

[0003] Conventional adjustable rebar positioning tools can only be fixed by fitting them on the outside of the main rebar. They lack a scale, resulting in low fixing accuracy. Furthermore, they are affected by the diameter of the rebar, and column rebars of different diameters may not be able to be clamped or may not be clamped at all. Summary of the Invention

[0004] The purpose of this utility model is to provide a column rebar positioning tool with high precision and flexibility to solve the problems of rebar misalignment, low positioning accuracy and influence from rebar diameter mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-precision assembled column rebar positioning tool is used to position the vertical rebar of columns during the construction of concrete structures in building engineering, preventing rebar displacement during concrete pouring. It belongs to the field of concrete structure rebar engineering construction. It includes: telescopic rods and sliding legs; the sliding legs are sleeved on the telescopic rods and can rotate or slide horizontally along the rods; four telescopic rods are fixed end-to-end to form an adjustable rectangular frame for outer casing of the column or inner support of the column rebar; the two sliding legs hold the rebar in place for positioning.

[0007] The aforementioned high-precision assembled column rebar positioning tool is formed by connecting and fixing inner and outer round tubes. The outer round tube has a hole on its outer wall, and the inner and outer round tubes are fixed by fastening bolts.

[0008] The aforementioned high-precision assembled column rebar positioning tool has a sliding support leg that is welded together from a ring assembly and a rebar support leg. The ring assembly has a fixing hole, and the sliding support leg is fitted onto the telescopic rod by means of the ring assembly and fixed by means of fastening bolts.

[0009] The aforementioned high-precision assembled column rebar positioning tool has a scale on the outer circumference of the inner and outer circular tubes.

[0010] The number of sliding legs in the aforementioned high-precision assembled column reinforcement positioning tool is determined based on the number of main reinforcement bars in the concrete column.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) The sliding support leg is connected to the telescopic rod by means of a ring fitting. The ring fitting is not affected by the specifications of the steel bars, the quantity of steel bars, or the column cross section.

[0013] (2) The sliding support leg can rotate 360 ​​degrees around the telescopic rod, which can both externally hoop the column reinforcement and internally support the column reinforcement, making it flexible and convenient;

[0014] (3) A scale is added to the outer periphery of the telescopic rod, which greatly improves the positioning accuracy;

[0015] (4) The overall structure is simple, it can be reused, it is easy to disassemble, and it is convenient to store and transport. Attached Figure Description

[0019] The technical solutions of the present invention will now be described in detail with reference to the accompanying drawings of the embodiments. Example

[0020] Please see Figure 1-2 This utility model provides a high-precision assembled column rebar positioning tool, comprising:

[0021] An outer circular tube 1 is inserted into an inner circular tube of a smaller size. A fastening bolt 3 is installed in the outer wall of the outer circular tube 1. The inner and outer circular tubes are connected to form a telescopic rod. The four telescopic rods are fixed end to end to form a rectangular frame. When in use, the entire structure is scaled up and down by the telescopic rods and then fixed by the fastening bolt 3.

[0022] The sliding support leg is welded from a ring assembly 4 and a steel reinforcement leg 5. A larger-sized ring assembly 4 is fitted over the outer tube 1 to attach the sliding support leg to the telescopic rod. The ring assembly 4 can rotate around the telescopic rod, allowing the steel reinforcement leg 5 to move inward or outward. The ring 4 has holes for securing it to the telescopic rod with bolts 6. In use, the two steel reinforcement legs 5 are used to hold the main reinforcement bar of the column for positioning. The sliding support leg is a split structure, accommodating the positioning of main reinforcement bars of different diameters, and its position on the telescopic rod is adjustable, improving flexibility.

[0023] Regularly engrave scale lines 7 on the inner and outer circular tubes to precisely adjust the size and position of the outer circular tube 1 and the ring 4.

[0024] Working principle: In use, according to the number of main reinforcement bars in the concrete column, an appropriate number of sliding legs are fitted onto the telescopic rod. Based on the column size, the method of outer column support or inner column reinforcement support is selected. The steel reinforcement legs 5 of the sliding legs are then oriented inward or outward. The size of the outer round rod 1 is adjusted according to the scale line 7. The inner and outer round rods are fixed by fastening bolt 1 3. According to the design position of the main reinforcement bars, the position of the ring assembly 4 is adjusted according to the scale line 7. Fastening bolt 2 6 fixes the sliding legs to the telescopic rod. The steel reinforcement bars are positioned by two adjacent steel reinforcement legs 5. The operation is simple and convenient, and the main reinforcement bars of the column can be positioned with high precision. When not in use, fastening bolt 1 3 and fastening bolt 2 6 can be loosened to disassemble the entire structure, making it convenient for storage and transportation.
