Description

Technical Field

[0001] This utility model relates to the field of building fixing technology, and in particular to a high-strength cement nail for building. Background Technology

[0002] In the field of building construction, "base fixation" is a fundamental requirement that runs through decoration, installation, and repair. From small things like fixing cable trays and installing hanging parts to large things like building supports and temporary reinforcement, nails are needed to connect objects to the building base. However, as building materials are upgraded to "high strength and high hardness", the performance shortcomings of traditional nails are becoming increasingly prominent, which provides an inevitable opportunity for the research and development and application of high-strength cement nails.

[0003] However, when existing high-strength cement nails are driven into the interior of a building's concrete wall, the presence of stones, sand, and other materials inside the concrete can cause gaps between the cement nail and the concrete wall after it is driven in. Under subsequent vibration, these gaps can cause the cement nail to gradually loosen and eventually fall off.

[0004] Therefore, we provide a high-strength cement nail for construction to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength cement nail for construction, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength cement nail for construction, comprising a positioning and fixing bracket and a split-type plug-in expansion fixing and grouting stabilizing mechanism, wherein the split-type plug-in expansion fixing and grouting stabilizing mechanism is provided on one side of the positioning and fixing bracket. The split-type plug-in expansion fixing grouting stabilization mechanism includes a pre-embedded metal expansion component, a plug-in auxiliary expansion component, and a top grouting secondary fixing component. The pre-embedded metal expansion component is provided on one side of the positioning and fixing bracket, the plug-in auxiliary expansion component is provided on the other side of the positioning and fixing bracket, and the top grouting secondary fixing component is provided on the inner side of the plug-in auxiliary expansion component.

[0007] Preferably, the pre-embedded metal expansion assembly includes a split aluminum alloy expansion bracket and a welded claw hook. The lower end of the positioning and fixing bracket is welded and fixed with the split aluminum alloy expansion bracket, and the outer surface of the split aluminum alloy expansion bracket is welded and fixed with the welded claw hook.

[0008] Preferably, the plug-in auxiliary expansion assembly includes an integrated fixed top shell, a plug-in rod, and a reserved injection arc channel. An integrated fixed top shell is provided on the other side of the positioning and fixing bracket. The lower end of the integrated fixed top shell is fixedly connected to the plug-in rod, and a reserved injection arc channel is pre-opened on the surface of the plug-in rod.

[0009] Preferably, the top grouting secondary fixing assembly includes a steel protective shell, a cross-shaped sealing rubber sleeve, and an oblique injection channel. The steel protective shell is fixedly connected to the surface groove of the integrated fixed top shell. The cross-shaped sealing rubber sleeve is adhered to the surface of the steel protective shell. An oblique injection channel is opened through the inner side of the lower end of the steel protective shell.

[0010] Compared with the prior art, the beneficial effects of this utility model are: As shown in the figure, this utility model uses a split-type plug-in expansion fixing and grouting stabilizing mechanism. By setting up a pre-embedded metal expansion component, a deep groove of a specified size is pre-cut on the concrete surface, and the pre-embedded metal expansion component is inserted into it, making the end of the positioning and fixing bracket flush with the concrete wall. Next, the plug-in auxiliary expansion component is inserted into a pre-drilled hole on the surface of the positioning and fixing bracket, with the lower end of the internal plug-in nail rod being arc-shaped. During the insertion process, the size of the plug-in nail rod will expand the split aluminum alloy expansion bracket, allowing the welded claw hooks at both ends to insert into the inner wall of the concrete, achieving primary fixation of the cement nail. When the bottom of the integrated fixing top shell is hammered into the arc groove of the positioning and fixing bracket, the corresponding filling adhesive is injected into the inclined grouting channel, and the inner wall of the concrete is filled through the pre-drilled grouting arc on the surface of the plug-in nail rod, achieving secondary fixation of the cement nail.

The lower end of the positioning and fixing bracket 1 is welded and fixed with the split aluminum alloy expansion bracket 211, and the outer surface of the split aluminum alloy expansion bracket 211 is welded and fixed with the welded barbed hook 212. During the process of inserting the nail rod 222, the size of the nail rod 222 will expand the split aluminum alloy expansion bracket 211, so that the welded barbed hooks 212 at both ends are inserted into the inner wall of the concrete, thereby achieving the one-time fixation of the cement nail as a whole.

[0015] Furthermore, the insertion auxiliary expansion assembly 22 includes an integrated fixed top shell 221, an insertion nail rod 222, and a reserved grouting arc channel 223.

The insertion nail rod 222 is fixedly connected to the lower end of the integrated fixed top shell 221. A reserved grouting arc channel 223 is pre-opened on the surface of the insertion nail rod 222. When the bottom of the integrated fixed top shell 221 is hammered into the top groove of the positioning and fixing bracket 1, the corresponding filling adhesive is injected into the inclined grouting channel 233, and the concrete inner wall is filled through the reserved grouting arc channel 223 on the surface of the insertion nail rod 222, thereby achieving secondary fixing of the cement nail.

[0016] Furthermore, the top grouting secondary fixing assembly 23 includes a steel protective shell 231, a cross-shaped sealing rubber sleeve 232, and an oblique grouting channel 233. The steel protective shell 231 is fixedly connected to a groove on the surface of the integrated fixing top shell 221. The cross-shaped sealing rubber sleeve 232 is adhered to the surface of the steel protective shell 231. An oblique grouting channel 233 is formed through the lower inner side of the steel protective shell 231. Figure 3 It can be seen that the inclined injection channel 233 inside the integrated fixed top shell 221 is inclined through, and its bottom is directly connected to the reserved injection arc channel 223. When the adhesive is filled, it will fill the gap through the reserved injection arc channel 223.

[0017] Working principle: First, a high-strength cement nail for construction is installed at the designated location. During use, firstly, the insulating component 21 blocks the grounding current of the support base 1, preventing damage to the electronic building blocks on the upper side. Secondly, the insulating panel 212 has multiple insulating pits 221 and fixing supports 222 on its surface. The fixing supports 222 can connect and fix various electronic building block components on the upper side, allowing for DIY experiments. Since the various electronic components on the support base 1 are modular and interconnected via connecting components 24, children can explore and assemble different modular components, enhancing their enjoyment. Thirdly, the resistor 31, load chip 32, and load device 33 inside the load component 3 are connected via a key to the inside of the insulating base 262. The current output and input can be controlled by the control component 25, enabling real-time observation and control of the load component 3.
