Technical Field
[0001] The utility model relates to the technical field of pre-embedded junction boxes, in particular to a pre-embedded junction box structure in a firmly installed concrete component. Background Art
[0002] The embedded junction box is an electrical accessory, mainly used to connect cables and wires. During the construction phase, it should be pre-embedded into building structures such as concrete, walls, and floors to protect the wiring. There are many types of embedded junction boxes. According to the wiring method, they can be divided into crimping type junction boxes, spiral type junction boxes, plug-in type junction boxes, etc.; according to the shape and function, they can be divided into round junction boxes, square junction boxes, optical cable junction boxes, etc.
[0003] Through research and analysis, it was found that the junction box still has the following disadvantages to a certain extent when it is pre-buried.
[0004] For example, if the fixation is not firm, it is easy to deviate and tilt, which may cause the junction box to shift and be damaged when pouring concrete, resulting in blockage of the embedded wiring conduit, making subsequent unblocking difficult, causing damage to the surface of the structural parts and increasing construction costs. In order to solve the above technical problems, we have designed a structure for embedding a junction box in a solid concrete component. Utility Model Content
[0005] The purpose of the utility model is to provide a pre-buried junction box structure in a firmly installed concrete component, which has the advantages of accurate positioning of the junction box and no displacement or damage during concrete pouring, and solves the problems of loose fixing, easy deviation and tilting, easy displacement and damage of the junction box during concrete pouring, resulting in blockage of the pre-buried wiring conduit, difficulty in subsequent unblocking, damage to the surface of the structural member, and increased construction cost.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pre-buried junction box structure in a firmly installed concrete member, comprising a junction box body, a protective cover mechanism movably sleeved on the surface of the junction box body, the protective cover mechanism comprising an annular rib, a first fixed rib and a second fixed rib, a connecting rib welded on the surface of the second fixed rib, and a positioning mechanism installed on the surfaces of the first fixed rib and the second fixed rib.
[0007] Preferably, both ends of the fixing rib 1 are welded to the surface of the annular rib, and both ends of the fixing rib 2 are welded to the surface of the fixing rib 1.
[0008] Preferably, the positioning mechanism comprises a short rib, one end of which is welded to the surface of the fixed rib one and the fixed rib two respectively, and the other end of the short rib is welded to a steel ring, and a fixing screw is provided through the surface of the steel ring.
[0009] Preferably, a through hole adapted to fit the fixing screw is provided on the surface of the steel ring, the steel ring is made by cutting discarded steel pipes, and the short bars are made by discarded steel bars and steel bar heads.
[0010] Preferably, the materials of the connecting ribs, the annular ribs, the first fixing ribs and the second fixing ribs are all discarded steel bars, and the annular ribs are formed by bending and welding steel bars.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] 1. The utility model selects a φ12-20 steel bar, processes it into 200mm length, makes it into connecting bars, uses φ6-10 steel bars to make two protective cover mechanisms with inner diameters of 80*80*50mm, welds the processed connecting bars to the prepared protective cover mechanisms, and effectively fixes the finished product on the shear wall steel bars at the location according to the position of the junction box. The embedded junction box is installed, and the outer edge of the junction box is tightly attached to the template surface when the template is installed to achieve the effect of fixed installation. The product is simple to make and easy to install, can be accurately positioned, and effectively prevents the junction box from being offset or damaged, effectively improves the quality of the embedded junction box, and greatly improves work efficiency and productivity.
[0013] 2. The raw materials in the utility model can all be discarded steel bars and steel bar heads, which improves the utilization rate of waste steel bar heads, saves resources, is easy to install, does not damage the longitudinal stress-bearing steel bars of the structural members, and effectively protects the quality of the main body of the structural members. The installation only needs to be tied to the longitudinal stress-bearing steel bars. Compared with welding fixation, it effectively protects the quality of the longitudinal bars and environmental pollution, and effectively solves the problem of junction box blockage. Compared with traditional pre-embedded, if the junction box is blocked, the pre-embedded junction box and the pre-embedded wire pipe will be partially or completely chiseled off, which will damage the appearance or structural quality of the concrete structure, and effectively improve the structural quality.
[0014] 3. The utility model inserts one end of the pre-buried wire tube connected to the pre-buried junction box into the steel ring, and then inserts the fixing screw through the through hole on the steel ring into the surface of the wire tube for connection, thereby positioning and limiting the wire tube. This has the advantage of being able to prevent the wire tube and the pre-buried junction box from falling off, effectively preventing the wire tube from falling off the pre-buried junction box when pouring concrete, thereby affecting the subsequent power construction.

By setting the steel ring 42, one end of the wire tube is inserted into the inside thereof and is limited to a certain position. A fixing screw 43 is penetrated through the surface of the steel ring 42. By setting the fixing screw 43, one end of the wire tube inserted into the steel ring 42 is fixed and positioned to prevent the wire tube from detaching from the steel ring 42, thereby reducing the probability of the wire tube detaching from the embedded junction box when pouring concrete.

The processed connecting ribs 3 are welded to the prepared protective cover mechanisms 2, and the completed product is effectively fixed on the shear wall steel bars at the location according to the position of the junction box. The embedded junction box is installed, and the outer edge of the junction box is tightly attached to the surface of the template during template installation to achieve the effect of fixed installation. The end of the embedded wire tube connected to the embedded junction box is inserted into the steel ring 42, and then the fixing screw 43 is inserted into the surface of the wire tube through the through hole 44 on the steel ring 42 for connection, and then the wire tube is positioned and limited, thereby having the advantage of being able to prevent the wire tube and the embedded junction box from falling off, effectively preventing the wire tube from falling off the embedded junction box during concrete pouring, and affecting the subsequent power construction.
