[0002] Building construction is the process of converting design drawings into physical buildings, involving multiple links such as foundation engineering, main structure, roofing engineering and decoration engineering construction. This process requires cross-operation of multiple types and multiple processes, and also requires a large amount of materials, mechanical equipment and human resources. In building construction, design requirements, construction specifications and safety production systems must be strictly followed to ensure construction quality and safety.

[0003] In building construction, two reinforcing bars often need to be connected together, so a building construction reinforcing bar quick joint is needed.

[0004] In the current technology, two groups of joints are usually used to connect with reinforcing bars, and after the connection is completed, the two groups of joints need to be fixed again using multiple groups of bolts, which not only makes the installation more troublesome, but also requires additional preparation of a large number of bolts for secondary connection, resulting in high cost, slow connection speed and affecting construction efficiency. Therefore, a building construction reinforcing bar quick joint is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0005] In order to make up for the above shortcomings, the utility model provides a building construction reinforcing bar quick joint, which aims to improve the problem of slow connection and responsible fixing of two groups of reinforcing bars in the prior art.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up a connecting ring, a sliding sleeve, a clamping ring and other structures, rotating the bolt causes the extrusion ring to move inward. At the same time, the inner inclined surface of the extrusion ring presses against the outer inclined surface of the clamping ring, causing the clamping ring to contract inward, thereby conveniently clamping the two sets of steel bars. It is convenient to use and the connection is relatively fast, ensuring construction efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-2 This utility model provides an embodiment of a quick-connector for steel bars used in building construction, comprising a connecting ring 1 for fixed connection, sliding sleeves 2 fixedly connected to both sides of the connecting ring 1, sliding grooves 3 formed inside the sliding sleeves 2, and threaded seats 4 fixedly connected to the outer side of the sliding sleeves 2. The threaded seats 4 are provided with eight sets, equidistantly arranged in a ring on the outer side of the sliding sleeves 2. A pressing assembly is threadedly connected inside the threaded seats 4, and the pressing assembly includes a bolt 5. The outer circumference of the bolt 5 is threadedly connected to the inside of the threaded seats 4. Rotating the bolt 5 allows the bolt 5 to move left and right on the inner wall of the threaded seats 4. The outer circumference of the bolt 5 is slidably connected to the inside of the sliding sleeves 2. An abutment block 6 is rotatably connected to the inner side of the bolt 5. The outer circumference of the abutment block 6 is slidably connected to the inside of the sliding grooves 3. The sliding grooves 3 restrict the abutment block 6 to slide left and right along the inner wall of the sliding grooves 3 and prevent it from rotating. A pressing ring 7 is in contact with the inner side of the pressing assembly.

[0032] Reference Figures 1-3The inner side of the abutting block 6 contacts the outer side of the extrusion ring 7, allowing the abutting block 6 to push the extrusion ring 7 inward. The outer periphery of the extrusion ring 7 is slidably connected to the inside of the sliding groove 3. The sliding groove 3 restricts the extrusion ring 7 to slide left and right along the inner wall of the sliding groove 3. The inside of the extrusion ring 7 contacts a clamping ring 9 that facilitates fixing the reinforcing bar. The clamping ring 9 has a certain elasticity and will deform after being extruded. The inner side of the extrusion ring 7 has an inner inclined surface 8, and the outer side of the clamping ring 9 has an outer inclined surface 10. The outer side of the outer inclined surface 10 and the inner side of the inner inclined surface 8 are matched in shape and in contact with each other. When the extrusion ring 7 moves inward, the clamping ring 9 can be tightened along the inclined surface. The inner side of the clamping ring 9 contacts the inner side wall of the sliding groove 3, preventing the clamping ring 9 from moving further inward and allowing it to retract inward. The front of the clamping ring 9 has a deformation notch 11, which allows the clamping ring 9 to retract inward.

[0033] Reference Figure 1 and Figure 4 The connecting ring 1 has four sets of welding ports 12 on its outer circumference, which are equidistantly arranged in a ring on the outer circumference of the connecting ring 1. A protective sleeve 13 is fixedly connected to the inner side of the connecting ring 1. The protective sleeve 13 is used to isolate the temperature and sparks during welding, so as to ensure that the strength of the connecting ring 1 is not affected. The protective sleeve 13 has four sets of through grooves 14 on its outer circumference, which are equidistantly arranged in a ring on the outer circumference of the protective sleeve 13. The position of the through grooves 14 corresponds to the position of the welding ports 12, which facilitates the welding of the internal reinforcing bars.

[0034] Working principle: When you want to easily connect two sets of reinforcing bars, slide the two sets of reinforcing bars into the sliding sleeve 2, then rotate the bolt 5. The bolt 5 pushes the abutment block 6 inward, and the abutment block 6 pushes the compression ring 7 inward. The compression ring 7 moves inward, and the inner inclined surface 8 of the compression ring 7 presses against the outer inclined surface 10 of the clamping ring 9, causing the clamping ring 9 to tighten and contract inward along the inclined surface, clamping the reinforcing bars. This makes it easy to connect the two sets of reinforcing bars together, and the clamping surface is large, making the clamping relatively stable. When you want to connect the two sets of reinforcing bars more securely, insert the welding torch into the welding port 12 and weld the contact points of the cross-sections of the two sets of reinforcing bars to improve the connection performance of the reinforcing bars. At the same time, the protective sleeve 13 can prevent sparks and high temperatures from affecting the connecting ring 1, ensuring the connection performance of the connecting ring 1.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
