Description

Technical Field

[0001] The utility model relates to the technical field of building steel bar skeletons, in particular to a forming column steel bar skeleton which is convenient for quick connection. Background Art

[0002] Steel bar skeletons are often used at construction sites. Steel bar skeletons are a more important part of building construction. Steel bar skeletons are usually constructed into steel cages by combining column steel bar skeletons and beam steel bar skeletons. For column steel bar skeletons used in buildings, they are usually raised in a stacked manner according to the needs of the operation. The uppermost end of the longitudinal reinforcement in the bottom steel bar skeleton is connected to the lowermost end of the longitudinal reinforcement in the upper steel bar skeleton to achieve height increase. Most of the existing methods for raising the column steel bar skeleton are usually welded. After aligning one pair of longitudinal reinforcements with a welding rod, a gap will be left between the upper and lower longitudinal reinforcements, and then the gap is circumferentially welded with the welding rod, so that the upper and lower longitudinal reinforcements are welded together, which has strong stability.

[0003] As for the construction site, the connection is made by welding. After aligning the upper and lower longitudinal bars of the upper and lower column steel frame one by one, the workers will weld the gaps of one pair of longitudinal bars to ensure that all the gaps are welded. The welding gun and the welding rod need to be constantly moved according to the position of the annular gap. The adjacent aligned longitudinal bars will interfere with the position of the welding gun and the welding rod. At the same time, it is also difficult to weld the longitudinal bars close to the inside. Therefore, the welding method will make the entire heightening process more difficult, inefficient, and the labor intensity of the workers higher. Utility Model Content

[0004] The utility model provides a formed column steel bar skeleton which is convenient and quick to connect. Compared with the welding method, the utility model directly connects the lower longitudinal reinforcement with the grouting sleeve through the arranged grouting sleeve by means of thread. After grouting multiple grouting sleeves at the same time, the solidification of the slurry is utilized to fix the position of each upper longitudinal reinforcement placed in each grouting sleeve at the same time. This heightening method is more convenient than the welding method and reduces the labor intensity of the workers. At the same time, the connection efficiency is higher by utilizing the method of simultaneous alignment, grouting and installation.

[0022] refer to Figure 1 , Figure 2 and Figure 3 The utility model provides a convenient and quick-connected formed column reinforcement skeleton, comprising a lower column reinforcement skeleton 1, an upper column reinforcement skeleton 2, and a plurality of grouting sleeves 3 for grouting. The lower column reinforcement skeleton 1 comprises a plurality of vertically arranged lower longitudinal bars 11, each of which has an external thread 111 at the upper end, and each of which is connected by binding with a plurality of lower stirrups 12; the upper column reinforcement skeleton 2 is located directly above the lower column reinforcement skeleton 1, and comprises a plurality of vertically arranged upper longitudinal bars 21, and the positions of the upper longitudinal bars 21 and the lower longitudinal bars 11 correspond one to one, and each of which is connected by binding with a plurality of upper stirrups 12. The stirrups 22 are tied and connected; a plurality of grouting sleeves 3 for grouting are arranged between the lower column steel bar skeleton 1 and the upper column steel bar skeleton 2, the number of the grouting sleeves 3 is consistent with the upper longitudinal bar 21, the position of each grouting sleeve 3 corresponds to the upper longitudinal bar 21, the inner diameter of the grouting sleeve 3 is larger than the outer diameter of the upper longitudinal bar 21, and each grouting sleeve 3 is tied and connected by the sleeve stirrups 4. The bottom of the grouting sleeve 3 is arranged in a downward cone shape, the inner diameter of the cone bottom opening matches the outer diameter of the upper longitudinal bar 21, and the inner wall of the cone bottom opening of the grouting sleeve 3 is provided with an internal thread 31 connected with the external thread 111 of the lower longitudinal bar 11.

[0023] In the above embodiments, the lower column steel frame 1 and the upper column steel frame 2 can be combined into the steel cage required for the building through binding. The grouting sleeve 3 does not need to set grouting holes and grouting holes, and high-strength grouting materials, such as concrete cement, can be directly poured in. The grouting is not filled up, and 10%-20% of the space is reserved to prevent the grouting material from leaking after the upper longitudinal reinforcement is inserted. The condensation of the high-strength grouting material is used to quickly connect the upper column steel frame 2 and the lower column steel frame 1. The grouting sleeve 3 is a hollow cylinder. The multiple lower stirrups 12 that can be set can have the effect of binding and fixing the lower longitudinal reinforcements 11 arranged respectively. The specific binding method is the commonly used existing binding method. The multiple upper stirrups 22 that are set can have the effect of binding and fixing the upper longitudinal reinforcements 21 arranged respectively. The specific binding method is also the commonly used existing binding method. The upper end of each lower longitudinal reinforcement 11 is opened An external thread 111 is provided, and an internal thread 31 is provided at the tapered mouth at the bottom of the grouting sleeve 3, so that the grouting sleeve 3 can be connected to the lower longitudinal reinforcement 11 through the internal thread 31. The upper opening of the grouting sleeve 3 can realize the insertion of the lower end of the upper longitudinal reinforcement 21. Therefore, compared with the welding method, the present connection method directly connects the grouting sleeve 3 with the lower longitudinal reinforcement 11 by threading, and utilizes the coagulation of slurry to realize the position fixation of each upper longitudinal reinforcement 21 placed in each grouting sleeve 3 at the same time. This heightening method is more convenient than the welding method and reduces the labor intensity of workers. At the same time, the upper longitudinal reinforcement 21 is used to align the grouting sleeve 3 and insert it, and the grouting is performed at the same time to make the connection efficiency higher. At the same time, the coagulation of slurry can be used to ensure the installation strength, and the threaded connection method between the grouting sleeve 3 and the lower longitudinal reinforcement 11 is used to facilitate installation and later disassembly.

[0024] like Figure 4 and Figure 5 As shown, a positioning ring 32 is provided in the grouting sleeve 3. The positioning ring 32 is fixedly connected to the inner wall of the grouting sleeve 3 through a plurality of connecting blocks 321. The axis of the positioning ring 32 coincides with the axis of the grouting sleeve 3. The inner diameter of the positioning ring 32 matches the outer diameter of the upper longitudinal reinforcement 21.

[0025] In the above embodiments, a positioning ring 32 is provided in the grouting sleeve 3. Specifically, the positioning ring 32 is located at the upper opening of the grouting sleeve 3, which can guide and limit the upper longitudinal reinforcement 21. When the upper longitudinal reinforcement 21 is vertically inserted into the grouting sleeve 3 filled with high-strength grouting material, it is limited by the positioning ring 32 and can only be inserted vertically. When extending into the grouting sleeve 3, it will not be affected by the high-strength grouting material and will not tilt, thereby ensuring the stability of the upper column steel bar skeleton 2.

[0026] Further, refer to Figure 4 and Figure 5 There are multiple positioning rings 32 in each grouting sleeve 3.

[0027] In the above embodiments, by providing a plurality of positioning rings 32, the plurality of positioning rings 32 can be used to further limit the upper longitudinal reinforcement 21 vertically inserted into the upper opening of the grouting sleeve 3, so that the upper longitudinal reinforcement 21 needs to pass through two or more positioning rings 32, and the axis of the positioning ring 32 coincides with the axis of the grouting sleeve 3. Therefore, when the upper longitudinal reinforcement 21 is aligned with the upper opening of the grouting sleeve 3, it can only be inserted into the grouting sleeve 3 along the vertical direction to prevent the upper longitudinal reinforcement 21 from tilting during the insertion process.

[0028] Further, refer to Figure 1 , Figure 2 and Figure 3 The lower longitudinal bars 11 are combined to form a rectangular lower column reinforcement skeleton 1, the lower stirrups 12 are arranged in a "well" shape, and the upper column reinforcement skeleton 2 has the same shape as the lower column reinforcement skeleton 1.

[0029] In the above embodiments, the formed column reinforcement skeleton is designed for rectangular columns, so the enclosed lower column reinforcement skeleton 1 is rectangular. When other shapes are required, such as round columns, the lower longitudinal reinforcement 11, the upper longitudinal reinforcement 21, and the grouting sleeve 3 can be enclosed into a cylindrical shape, and the lower stirrups 12, the upper stirrups 22, and the sleeve stirrups 4 can be adaptively changed.

[0030] Further, refer to Figure 2 The length of the external thread 111 of the upper longitudinal rib 21 is 50 mm.

[0031] In the above embodiment, by limiting the length of the external thread 111 of the upper longitudinal reinforcement 21 to 50 mm, the grouting sleeve 3 can be connected to the upper longitudinal reinforcement 21 by spiral rotation, and part of the external thread 111 extends into the interior of the grouting sleeve 3, thereby improving the stability of the connection.

[0032] Further, refer to Figure 6 The upper end of each upper longitudinal rib 21 is provided with a thread groove 211 which is the same as the external thread 111 .

[0033] In the above embodiments, by providing a thread groove 211 identical to the external thread 111 at the upper end of each upper longitudinal reinforcement 21, a new grouting sleeve 3 can be used for connection, thereby achieving a multi-layer heightened connection effect.

[0034] Usage and working principle: When the factory produces the formed column steel bar skeleton, first tie the lower column steel bar skeleton 1, and tie multiple lower stirrups 12 with each lower longitudinal reinforcement 11 from top to bottom to form a steel cage. When the lower column steel bar skeleton 1 needs to be heightened and reinforced, the upper stirrups 22 are tied with each upper longitudinal reinforcement 21 from top to bottom in the same way to form an upper column steel bar skeleton 2.

[0035] When performing heightening installation, it is only necessary to connect the inner thread 31 of the lower cone portion of each grouting sleeve 3 with the outer thread 111 of each upper longitudinal reinforcement 21 by rotational threading. Figure 3 As shown, each grouting sleeve 3 is tied with sleeve stirrups 4. At this time, the upper column steel frame 2 is lifted by a crane and each upper longitudinal reinforcement 21 is aligned with the grouting sleeve 3 connected to the lower column steel frame 1. Then, the grouting machine is used to fill each grouting sleeve 3 with high-strength grouting material through multiple pipes at the same time. Then, each upper longitudinal reinforcement 21 is aligned with the positioning ring 32 in the corresponding grouting sleeve 3 and inserted. Each upper longitudinal reinforcement 21 will be vertically inserted into the grouting sleeve 3, and the slurry will be cooled and formed.

[0036] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
