Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, specifically to a pre-embedded structure for civil engineering construction. Background Technology

[0002] Embedded components in civil engineering construction are metal components pre-installed before concrete pouring. They are mainly used for subsequent structural connections, equipment installation, or fixing in decorative works. During construction, they must be positioned strictly according to the drawings, fixed by welding or bolts, and ensure a reliable connection with the reinforcing steel frame to prevent displacement during concrete vibration. After installation, anti-corrosion treatment is required, and temporary protection should be provided to prevent contamination during pouring. Key quality control points include positional deviation, welding strength, and anti-corrosion integrity, which directly affect the installation accuracy of subsequent curtain walls, pipelines, or steel structures. Traditionally, to avoid material brittleness caused by welding, embedded structures in civil engineering construction are usually fixed to the reinforcing steel frame using binding wires. However, the connection strength of binding wires is generally not strong, and the embedded structure is easily displaced by the impact of poured concrete. Utility Model Content

[0003] The purpose of this utility model is to provide a pre-embedded structure for civil engineering construction, in order to solve the problem mentioned in the background art that traditional pre-embedded structures for civil engineering construction usually use binding wires to fix the pre-embedded structure to the steel frame in order to avoid the brittleness of materials caused by welding. However, the connection of the binding wire fixing method is generally not firm, and the pre-embedded structure is easily displaced by the impact of poured concrete.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pre-embedded structure for civil engineering construction, including an embedded plate, with connecting nuts fixedly connected at the four corners of the embedded plate, through holes opened at positions corresponding to the connecting nuts on the embedded plate, and connecting screws threadedly connected to each of the four connecting nuts, with one end of the connecting screw extending into the through hole, an inner clamping plate provided on the other side between the upper and lower connecting screws, an outer clamping plate provided between the upper and lower connecting screws and between the inner clamping plate and the embedded plate, an inner clamping nut provided on the connecting screw and inside the inner clamping plate, and an outer clamping nut provided on the connecting screw and outside the outer clamping plate.

[0005] Preferably, the inner clamping plate and the outer clamping plate are slidably connected to the connecting screw, the inner clamping nut abuts against the inner clamping plate, and the outer clamping nut abuts against the outer clamping plate.

[0006] Preferably, the four connecting nuts are fixedly connected to the embedded plate by means of a connection, and the embedded plate has a process groove at the middle position and between the four connecting nuts.

[0007] Preferably, a tool clamping section is provided on each of the four connecting screws and between the connecting nut and the outer clamping nut.

[0008] Preferably, a clamping gap is provided between the inner clamping plate and the outer clamping plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are: it replaces the traditional method of fixing the pre-embedded structure to the steel frame using binding wires in civil construction, and fixes the pre-embedded structure to the outside of the steel frame structure by clamping the steel frame with inner and outer clamping plates, thereby improving the connection firmness of the fixing method and avoiding displacement caused by the impact of poured concrete on the pre-embedded structure during construction.

[0016] 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.

[0017] Please see Figure 1-5This utility model provides a pre-embedded structure for civil engineering construction, including an embedded plate 1. Connecting nuts 2 are fixedly connected to the four corners of the embedded plate 1. Through holes 3 are opened at the positions corresponding to the connecting nuts 2 on the embedded plate 1. Connecting screws 4 are threadedly connected to the four connecting nuts 2. One end of the connecting screw 4 extends into the interior of the through hole 3. An inner clamping plate 5 is provided on the other side between the upper and lower connecting screws 4. An outer clamping plate 6 is provided between the upper and lower connecting screws 4 and between the inner clamping plate 5 and the embedded plate 1. An inner clamping nut 7 is provided on the connecting screw 4 and inside the inner clamping plate 5. An outer clamping nut 8 is provided on the connecting screw 4 and outside the outer clamping plate 6.

[0018] In use, first connect the connecting screw 4 to the connecting nut 2 via threads, and insert one side of the connecting screw 4 into the through hole 3. When it is necessary to keep the outer surface of the embedded plate 1 flat, the connecting screw 4 is stored inside the through hole 3. When it is necessary to install bolts on the outside of the embedded plate 1, the connecting screw 4 extends out to the outside of the embedded plate 1 through the through hole 3. Connect the outer clamping plate 6 between the upper and lower connecting screws 4. Adjust the position of the outer clamping nut 8 to adjust the position of the outer clamping plate 6 to ensure that the outer surface of the embedded plate 1 is consistent with the outer surface of the poured concrete. Then connect the inner clamping plate 5 between the upper and lower connecting screws 4. Then fix the inner clamping plate 5 with the inner clamping nut 7 and tighten the inner clamping nut 7. The inner clamping plate 5 and the outer clamping plate 6 clamp and fix the steel frame to ensure the connection strength of the embedded plate 1 to the steel frame.

[0019] The inner clamping plate 5 and the outer clamping plate 6 are slidably connected to the connecting screw 4. The inner clamping nut 7 abuts against the inner clamping plate 5, and the outer clamping nut 8 abuts against the outer clamping plate 6. The position of the outer clamping plate 6 can be adjusted by adjusting the outer clamping nut 8, and the position of the inner clamping plate 5 can be adjusted by adjusting the inner clamping nut 6.

[0020] The four connecting nuts 2 are fixedly connected to the embedded plate 1 by means of connection. The embedded plate 1 has a process groove 9 in the middle position and between the four connecting nuts 2, which reduces the weight of the overall structure and leaves installation space for external bolt connections.

[0021] Tool clamping sections 10 are provided on the four connecting screws 4 and between the connecting nuts 2 and the outer clamping nuts 8. When adjusting the position of the connecting screws 4 relative to the connecting nuts 2, the operator uses a tool to clamp the tool clamping sections 10, so that the connecting screws 4 can be rotated and moved under the support of the connecting nuts 2.

[0022] A clamping seam 11 is provided between the inner clamping plate 5 and the outer clamping plate 6, through which the steel frame structure is clamped and fixed.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
