Description

Technical Field

[0001] This application relates to the fields of electrochemical water treatment and saline wastewater resource utilization treatment, and in particular to a threaded steel fixing and anti-detachment device. Background Technology

[0002] Rebar primarily serves to enhance structural strength and improve seismic performance in the construction field. It is widely used in concrete reinforcement, beam-column frames, and seismic design, making it an indispensable supporting material in modern buildings. The ribbed design of rebar enhances its bond with concrete, allowing the steel reinforcement and concrete to work together to bear loads, significantly improving the tensile and bending strength of buildings. During earthquakes, the ductility of rebar can reduce structural damage and prevent building collapse.

[0003] However, in practical applications, rebar may slip due to various reasons. Improper assembly, excessive tightening torque, or incorrect tightening sequence can lead to uneven stress on the threads, causing localized wear and slippage. Failure of the protective layer, resulting in exposed rebar, accelerates corrosion, reduces the effective diameter and load-bearing capacity, indirectly increasing the probability of slippage. Welding issues, such as substandard spot welding, weaken the connection strength and increase the risk of leakage during the rainy season, indirectly leading to structural loosening. In building structures, slippage of rebar can cause joint failure, weakening the structural load-bearing capacity. Under the influence of external forces such as earthquakes or strong winds, loosened rebar may become the starting point of structural failure, increasing the risk of collapse.

[0004] Therefore, there is an urgent need in this field for a device that can reduce the possibility of rebar slippage in order to reduce the building damage caused by rebar slippage. Utility Model Content

[0005] The purpose of this invention is to reduce the possibility of slippage of rebar in the construction field, minimize the damage to buildings caused by rebar slippage, and propose a rebar fixing and anti-slippage device.

[0006] The threaded steel fixing and anti-detachment device provided in this application adopts the following technical solution: A threaded steel bar fixing and anti-detachment device includes an anti-detachment seat fixedly connected to a building structure, through which the threaded steel bar passes. The anti-detachment seat has at least one anti-detachment rod with anti-slip texture on one side of the threaded steel bar in the direction of threading. An anti-slip rope is tied to the outer wall of the threaded steel bar on the side of the threaded steel bar passing through the anti-detachment seat away from the anti-detachment rod, and the other end of the anti-slip rope is tied to the anti-detachment rod.

[0007] Preferably, the anti-slip rope is a stainless steel wire rope, and both ends of the anti-slip rope are respectively wound around the threaded steel and the outer wall of the anti-detachment rod and fixed by a clamp.

[0008] Furthermore, two anti-detachment rods are provided, which are respectively located on both sides of the threaded steel. The anti-slip rope is wound around the outer wall of the threaded steel on the side of the anti-detachment seat away from the anti-detachment rod to form two sections of rope located on the left and right sides of the threaded steel. The two ends of the anti-slip rope are wound around the two anti-detachment rods respectively, and the two ends of the anti-slip rope are fixed to the corresponding anti-detachment rods by the locking buckle.

[0009] Furthermore, the anti-slip rope is composed of two sections of rope separated by the threaded steel, which are fixed on the winding side by the locking buckle to form an anti-slip loop that is sleeved on the outside of the threaded steel.

[0010] Preferably, the anti-detachment seat has an anti-detachment plate on the side opposite to the anti-detachment rod, and the threaded steel bar passes through the anti-detachment plate and is threadedly connected to the anti-detachment plate.

[0011] Preferably, the anti-detachment seat includes an anti-detachment base plate, a connecting plate, and a reinforcing plate. The anti-detachment base plate is used to fix and connect to the building structure. Two connecting plates are provided on the side of the anti-detachment base plate away from the building structure. The two connecting plates are respectively provided on both sides of the anti-detachment base plate for threading the threaded steel. Two reinforcing plates are provided at intervals. The two connecting plates are connected by the reinforcing plates and simultaneously connected to the anti-detachment base plate. The threaded steel is located between the two reinforcing plates. The anti-detachment rod is provided on one of the connecting plates.

[0012] Furthermore, the threaded plate has a waist-shaped slot on the side where the anti-detachment rod is located, for the threaded steel to pass through.

[0013] Preferably, the anti-detachment seat is provided with a fixed seat, and the anti-detachment rod is detachably inserted into the fixed seat.

[0014] Compared with the prior art, the threaded steel fixing and anti-detachment device of this utility model has the following beneficial technical effects: 1. The threaded steel fixing and anti-slip device of this utility model sets an anti-slip rod on one side of the threaded steel through the anti-slip seat, and binds an anti-slip rope between the anti-slip rod and the outer wall of the other side of the threaded steel through the anti-slip seat. When the threaded steel has a tendency to slip, the fixing force of the building and the anti-slip seat itself pulls the threaded steel to eliminate or slow down the slippage tendency, thereby reducing the risk of threaded steel slippage.

[0015] 2. This utility model further improves the upper limit of the anti-slipping device in dispersing the prestress of the threaded steel when it slips out by using two anti-slipping rods.

[0016] 3. This utility model provides an anti-slip plate connected to the threaded steel bar on one side of the anti-slip seat. When the threaded steel bar has a tendency to slip, it will not only be subjected to the tension of the anti-slip rope, but also the frictional resistance of the anti-slip plate, which further reduces the possibility of the threaded steel bar slipping.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains. The use of terms such as "a" or "an" in this patent application specification and claims does not indicate a limitation of quantity, but rather indicates the presence of at least one.

[0020] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0021] This application discloses a device for fixing and preventing the detachment of threaded steel bars.

[0022] Reference Figure 1 and Figure 2A threaded steel bar fixing and anti-slip device includes an anti-slip seat 1 fixedly connected to a building structure 8, a threaded steel bar 2 passing through the anti-slip seat 1, and at least one anti-slip rod 3 with anti-slip texture on one side of the anti-slip seat 1 in the direction of threaded steel bar 2 passing through. An anti-slip rope 4 is tied to the outer wall of the threaded steel bar 2 on the side of the anti-slip seat 1 opposite to the anti-slip rod 3, and the other end of the anti-slip rope 4 is tied to the anti-slip rod 3. When the threaded steel bar 2 has a tendency to slip, the fixing force of the building and the anti-slip seat 1 itself acts on the wire rope, thereby pulling the threaded steel bar 2 to eliminate or slow down the slippage tendency, thereby reducing the risk of the threaded steel bar 2 slipping. The threads on the outer wall of the threaded steel bar 2 and the anti-slip texture on the anti-slip rod 3 play the role of converting friction into tension. In this embodiment, the anti-slip seat 1 is fixedly connected to the building structure 8 by a threaded rod and a nut, and the anti-slip rod 3 can also be made of threaded steel bar 2.

[0023] Reference Figure 1 and Figure 2 The anti-slip rope 4 is a stainless steel wire rope. The two ends of the anti-slip rope 4 are respectively wrapped around the outer wall of the threaded steel 2 and the anti-detachment rod 3 and fixed by the clamp head lock 5. The clamp head lock 5 adopts a special U-shaped clamp head for wire rope, which is existing technology and will not be described in detail.

[0024] Furthermore, two anti-slip rods 3 are installed, one on each side of the threaded steel bar 2. The anti-slip rope 4 is wrapped around the outer wall of the threaded steel bar 2 on the side opposite to the anti-slip rod 3 where the anti-slip seat 1 is installed, forming two sections of rope on the left and right sides of the threaded steel bar 2. The two ends of the anti-slip rope 4 are wrapped around the two anti-slip rods 3 respectively, and the two ends of the anti-slip rope 4 are fixed to the corresponding anti-slip rod 3 by means of the buckle 5. In this way, the prestress of the threaded steel bar 2 when it slips can be dispersed by the two anti-slip rods 3, which further improves the upper limit of the anti-slip device in dispersing the slip stress of the threaded steel bar 2.

[0025] Furthermore, the anti-slip rope 4, which is divided into two sections by the threaded steel 2, is fixed on the winding side by the clamp and buckle 5 to form an anti-slip ring that is sleeved on the outside of the threaded steel 2. This can increase the contact area between the anti-slip rope 4 and the threaded steel 2, thereby reducing the possibility of slippage between the anti-slip rope 4 and the threaded steel 2, which weakens the pulling effect.

[0026] Reference Figure 1 and Figure 2 An anti-slip plate 6 is installed on the side of the anti-slip seat 1 away from the anti-slip rod 3. The threaded steel bar 2 passes through the anti-slip plate 6 and is threadedly connected to the anti-slip plate 6. When the threaded steel bar 2 has a tendency to slip, the threaded steel bar 2 will not only be subjected to the tension of the anti-slip rope 4, but also to the frictional resistance of the anti-slip plate 6, which further reduces the possibility of the threaded steel bar 2 slipping.

[0027] Reference Figure 1 and Figure 2The anti-detachment seat 1 includes an anti-detachment base plate 11, a through plate 12, and a reinforcing plate 13. The anti-detachment base plate 11 is used to fix and connect the building structure 8. Two through plates 12 are welded and fixed on the side of the anti-detachment base plate 11 away from the building structure 8. The two through plates 12 are respectively arranged on both sides of the anti-detachment base plate 11 for threaded steel bars 2 to pass through. Two reinforcing plates 13 are arranged at intervals. The two through plates 12 are welded and fixed through the reinforcing plates 13. The reinforcing plates 13 are also welded and connected to the anti-detachment base plate 11 to enhance the overall structural strength of the anti-detachment seat 1. The threaded steel bars 2 are located between the two reinforcing plates 13. The anti-detachment rod 3 is installed on one of the through plates 12.

[0028] Furthermore, the through plate 12 has a waist-shaped slot 121 on one side where the anti-detachment rod 3 is provided for the threaded steel 2 to pass through. The waist-shaped slot allows the threaded steel 2 to have the ability to produce a slight displacement during the fixing and anti-detachment process, effectively compensating for processing errors and installation deviations, and ensuring a firm connection between the threaded steel 2 and the anti-detachment seat 1.

[0029] Reference Figure 2 A fixed seat 7 is welded and fixed on the anti-detachment seat 1. The anti-detachment rod 3 is detachably inserted into the fixed seat 7. Specifically, the anti-detachment rod 3 and the fixed seat 7 are connected by an interference fit, which can realize detachment for easy maintenance and replacement, improve the overall service life of the equipment, and ensure the connection stability during the anti-detachment process.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
