Description

Technical Field

[0001] The utility model relates to the field of embedded nuts, and more specifically to a high-strength embedded embedded nut for construction. Background Art

[0002] Embedded nuts are one of the important structural parts in the foundry and manufacturing industries, also known as embedded nuts. In the process of construction, many important components need to rely on embedded nuts to fix them, such as the fixation of tower crane bases and the installation of concrete walls. Embedded nuts have high strength and are easier to operate during later construction. They can improve the accuracy of component installation and avoid large errors caused by relevant personnel relying only on simple tools for measurement during operation.

[0003] There are also certain problems in the use of embedded pre-embedded nuts. After the pre-embedded nuts are fixed, concrete needs to be poured around them. Concrete can easily penetrate or splash into the nuts, causing damage to the threads or residual solidified concrete inside. The bolts cannot be normally turned into the nuts during later installation. Moreover, the bolts are stored at the construction site for a long time, and they are prone to accumulate dust and other impurities, which will affect the accuracy of installation of the pre-embedded nuts and the fixing strength during later use. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a high-strength embedded pre-buried nut for construction. The nut has a removable top cover during installation to prevent concrete from entering. Impurities on the bolt thread can be cleaned when the bolt is screwed into the nut, making installation convenient and less affected by dust and impurities in the connection strength.

[0006] 2. Technical solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A high-strength embedded pre-embedded nut for construction, comprising a nut shell, a screw core hole is provided in the center of the nut shell, a nut base is fixedly installed at the lower end of the nut shell, a nut limiting opening is provided at the upper end of the nut shell, a limiting ring is annularly installed on the outer side of the nut limiting opening, a screw cover is provided at the upper end of the nut limiting opening, a group of reinforcing nails are provided on the inner surface of the screw cover, and the reinforcing nails match the limiting ring, a group of annularly distributed cavities are provided inside the nut limiting opening, a plurality of first limiting grooves are provided inside the nut limiting opening, and the first limiting grooves are provided at the upper end of the cavity and connected to the cavity, a plurality of second limiting grooves are provided inside the nut limiting opening, and the second limiting grooves are connected to the cavities. The nut limit opening has a cavity and a screw core hole, a connecting rod mechanism is installed inside the nut limit opening, and the connecting rod mechanism includes a pressure rod, a connecting rod, a push rod, a hand rod, and a clamping plate. The inner wall of the nut limit opening is provided with a substrate, and the substrate is fixedly connected to the connecting rod mechanism on the side close to the inner wall of the nut limit opening, and a cleaning brush head is installed on the side of the substrate away from the inner wall of the nut limit opening. This scheme prevents impurities such as concrete mortar from entering the screw core hole and affecting the normal use of the thread by covering the embedded nut. The screw cover can be easily removed and used multiple times, thereby reducing production costs. After the bolt is inserted, it is manually operated so that the cleaning brush head is close to the bolt thread, and impurities on the thread are naturally cleaned when the embedded nut is screwed in, so that the installation of the nut and the thread is not hindered.

[0009] Furthermore, the pressure rod is arranged in the first limiting groove, and the pressure rod matches the first limiting groove, the connecting rod is movably connected to the pressure rod, and the connecting rod is arranged in the cavity, the push rod is arranged in the second limiting groove, and the push rod matches the second limiting groove, and the push rod is movably connected to the connecting rod. In this scheme, the connecting rod and the push rod can be driven by pressing the pressure rod with external force to push the substrate and the cleaning brush head inward. When the bolt is inserted into the screw core hole, the cleaning brush head can squeeze and clean its surface when the bolt rotates.

[0010] Furthermore, a group of limiting walls are installed at the upper end of the nut limiting mouth, and the limiting walls are close to the first limiting groove. A group of limiting slots are provided on the limiting walls, and the limiting slots are arranged vertically from top to bottom. A hand rod is installed at the upper end of the pressure rod, and a clamping plate is installed on the upper part of the pressure rod, and the clamping plate matches the limiting slots. This solution enables the cleaning brush head to be positioned stably and the extrusion force can be adjusted according to the situation through the engagement of the clamping plate with the limiting slots at different positions, so that the impurities in the bolts can be cleaned more cleanly. After the bolts and nuts are fixed, the cleaning brush head can also prevent external dust and impurities from entering the screw core hole to a certain extent.

[0011] Furthermore, a first indicator block is provided on the outer wall of the nut limit opening, and a second indicator block matching the first indicator block is provided on the outer side of the screw cover. In this solution, when the first indicator block and the second indicator block correspond to each other, the limit ring and the reinforcement nail are just staggered, and the screw cover can be installed or removed at this time, making it more convenient for personnel to install and remove the screw cover, thereby improving installation efficiency.

[0012] Furthermore, the outer wall of the nut shell is provided with a zinc coating. In this solution, the corrosion resistance of the embedded nut is improved by electroplating the zinc coating on the nut shell, thereby avoiding the influence of corrosion on the strength of the building or equipment installation.

[0013] Furthermore, a plurality of groups of conical reinforcing nails are installed on the outer wall of the nut shell. This solution improves the connection strength between the embedded nut and concrete through the plurality of groups of reinforcing nails, thereby improving the overall strength of the embedded nut during use.

The screw cover can be easily removed and used multiple times, reducing production costs. After the bolt is inserted, the cleaning brush head is manually operated so that it is close to the bolt thread. When the embedded nut is screwed in, impurities on the thread are naturally cleaned, so that the installation of the nut and thread is not obstructed.

[0017] (2) In this solution, the connecting rod and the push rod can be driven by pressing the pressure rod with external force, thereby pushing the base plate and the cleaning brush head inward. When the bolt is inserted into the screw core hole, the cleaning brush head can squeeze and clean the surface of the bolt when it rotates.

[0018] (3) This solution makes the cleaning brush head stable in position and can adjust the squeezing force according to the situation through the engagement of the card plate with the limit card slots at different positions, so that the impurities on the bolts can be cleaned more thoroughly. After the bolts and nuts are fixed, the cleaning brush head can also prevent external dust and impurities from entering to a certain extent. This solution uses the first indicator block and the second indicator block to correspond to each other. When the limit ring and the reinforcement nail are just staggered, the screw cover can be installed or removed at this time, making it more convenient for personnel to install and remove the screw cover, thereby improving installation efficiency.

[0019] (4) This solution improves the corrosion resistance of the embedded nut by electroplating the zinc coating on the nut shell, thereby preventing the strength of the building or equipment installation from being affected by corrosion.

[0020] (5) This scheme improves the connection strength between the embedded nut and the concrete through multiple sets of reinforcement nails, thereby improving the overall strength of the embedded nut. BRIEF DESCRIPTION OF THE DRAWINGS
