Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of construction, and in particular relates to a multi-directional steel bar connection device. Background Art
[0002] Ribbed steel bars, also called threaded steel bars, deformed steel bars or threaded steel bars, are widely used in all aspects of construction projects, especially in the production of reinforced concrete. At present, in the construction industry, traditional steel bar connection methods include lap joints and welding, which cannot meet the needs of the construction industry in terms of connection quality, efficiency or operability. The lap joint connection method cannot be used to connect large-sized steel bars. However, welding has many shortcomings: such as unstable steel material, poor weldability, tight construction period or poor welder skills, unstable power supply, insufficient capacity, weather influences such as wind, rain and cold, and construction in places with high fire protection requirements.
[0003] A connecting sleeve is usually used to connect the steel bar heads of two ribbed steel bars. my country's construction industry industry standard (JG163-2004) has made clear provisions on the material, threaded connection strength, quality inspection standards, packaging and transportation of the connecting sleeve, but the "standard" does not make clear provisions on the appearance of the connecting sleeve.
[0004] At the same time, the inventors have found in practice that there are problems when using the connecting sleeve of the above-mentioned structure. This problem is mainly reflected in: since the surface of the connecting sleeve is smooth, the tool has no fulcrum and is easy to slip, which increases the difficulty of construction and reduces the construction efficiency. In addition, it may also cause the adhesion between the connecting sleeve and the concrete joint to be inconsistent with the adhesion between the ribbed steel bar and the concrete joint, which in turn leads to local quality risks in the structure at the buried position of the connecting sleeve on the reinforced concrete, so that when the reinforced concrete is subjected to force, the reinforced concrete at the connecting sleeve cannot share the load stress synchronously with the reinforced concrete at the ribbed steel bar. In severe cases, the reinforced concrete may break or peel off at the connecting sleeve. Summary of the invention
[0005] The purpose of the present invention is to provide a multi-directional steel bar connection device, which can realize multi-directional connection of steel bars, is easy to operate and has multiple functions. It can also realize fast and accurate positioning connection between steel bars, thereby improving the construction progress of reinforced concrete structures.
[0006] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:
[0007] A multi-directional steel bar connection device comprises an upper structure, a spring component, a rigid body, a protruding cylinder, a lower structure and an L-shaped groove, wherein the upper surface of the upper structure is provided with two bolt holes, one bolt hole is respectively provided on the left, right, front and rear sides; the lower part of the upper structure is provided with four cylindrical grooves; the front, rear, left and right sides of the upper structure are respectively provided with two L-shaped grooves; the lower surface of the lower structure is provided with two bolt holes, one bolt hole is respectively provided on the left, right, front and rear sides; the front, rear, left and right sides of the lower structure are provided with an inserting body which can be inserted into the L-shaped groove of the upper structure; the upper surface of the lower structure is provided with four cylindrical protrusions which are tightly inserted into the groove of the upper structure.
[0008] Furthermore, the puzzle body includes a protruding cube, a spring and a protruding structure; the bottom end of the protruding cube is connected to the front, rear, left and right surfaces of the lower structure, and the top end is connected to the spring and the protruding structure. The three parts of the protruding cube, spring and protruding structure form a unified and stable L-shaped structure, which matches the L-shaped groove.
[0009] Furthermore, the lower surface of the protruding structure is smooth, and the upper surface is flat.
[0010] The advantages and beneficial effects of the present invention are:
[0011] 1. When the upper structure and the lower structure of the multi-directional steel bar connection device of the present invention are connected, the protruding structures on both sides of the lower structure will be squeezed in with the side plane of the upper structure, and the cylindrical protrusion and the groove in the middle will be connected first, and the connection is tight without leaving any gaps. When the cylindrical protrusion and the groove are completely wedged, the lower edges of the protruding structures on the left and right sides just pop out and wedged with the upper structure, and the force generated by the two is used for effective fixation.
[0012] 2. The surface of the entire structure of the present invention is provided with multiple bolt holes, which can quickly and accurately locate and connect the steel bars in three directions in space, and can realize the connection of steel bars in multiple directions.
