Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a prefabricated wall connecting part which is easy to install and dismantle. Background Art

[0002] With the rapid development of the construction industry, the performance and technical requirements of wall ties, as important components connecting building structures and external frames, have received increasing attention. Wall ties are used to connect and fix construction platforms / scaffoldings during construction, or to connect decorative parts / structural components on exterior walls.

[0003] Traditional wall ties are generally implemented in two ways. One is to reserve a through hole on the wall and then fix the supporting components in the through hole. In this method, if the hole diameter of the through hole is too large, it is easy to reduce the strength of the wall. The other is to set embedded parts when pouring the wall, but the embedded parts usually extend from the inside of the wall. Therefore, the above methods have problems such as positioning deviation, poor durability, and difficulty in installation and disassembly, and involve a lot of cutting, repairing and other work, which not only wastes manpower and material resources, but may also have a certain impact on structural safety, and cannot meet the requirements of modern buildings for safety, efficiency, and environmental protection. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a pre-installed wall connection member that is easy to install and disassemble, including a fastener, one end of which is provided with a first nut, a double-headed screw rod inserted into the interior of the fastener, and one end of the double-headed screw rod is threadedly matched with the first nut. The fastener is a tubular member, which is pre-buried in the wall. The double-headed screw rod is separated from the first nut, so that it can be removed from the fastener, which is convenient for disassembly and installation.

[0005] The other end of the double-headed screw is sleeved with a fastener for connecting the pipe fitting. The fastener is a tight hoop for embracing and fixing the pipe fitting.

[0006] Preferably, the fastener is a two-petal structure, the two petals are rotatably connected, one petal is sleeved on a double-headed screw, and the other end of the double-headed screw is threadedly matched with a second nut. The fastener is fixed by the second nut.

[0007] Preferably, a bolt is inserted into one of the petals, the bolt passes upward to the end of the other petal, and a third nut is threadedly provided on the bolt to fix the two petals of the fastener by the third nut and the bolt.

[0008] Preferably, a spring washer is provided below the third nut to improve the stability of the connection.

[0009] Preferably, one end of the fastener is provided with a regular hexagonal groove, and the first nut fits exactly in the groove, thereby preventing the first nut from rotating and facilitating the connection and separation of the double-headed screw.

[0010] Preferably, the end of the fastener is buckled with a tail sleeve, and the tail sleeve covers the first nut. If one end of the fastener is cast inside the wall, the tail sleeve is used to block one end of the fastener and reserve sufficient axial space for the connection of the stud screw, thereby preventing concrete from entering the interior of the fastener and improving the degree of connection between the stud screw and the first nut.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The present invention provides fasteners, stud screws, fasteners, etc., and adopts a threaded connection method to facilitate disassembly and assembly, improve construction quality, and at the same time, the fasteners do not extend from the outside of the wall, and there is no need for subsequent processing such as cutting.

[0013] 2. Use prefabricated fasteners to fix on the template, which improves positioning accuracy and stability. At the same time, due to the special structure of the fasteners, welding with steel bars is avoided, reducing the use of other tools.

[0014] 3. By replacing the corresponding fasteners, this design can be flexibly applied to external frame systems of different types and sizes, reducing costs and improving production efficiency while ensuring quality and safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. Example

[0022] Combination Figure 1 and Figure 2 As shown, a pre-installed wall connection part that is easy to install and disassemble includes a fastener 2, which is a tubular part and is preset and fixed when the wall 11 or the building is cast. At the same time, left and right convex rings are provided at both ends of the fastener 2 to facilitate finding the position of the fastener 2 during subsequent connection and fixation. A first nut 4 is provided at one end of the fastener 2, and a double-headed screw 5 is inserted inside the fastener 2, and one end of the double-headed screw 5 is threadedly matched with the first nut 4, that is, the double-headed screw 5 is inserted into the interior of the fastener 2, and then the double-headed screw 5 is rotated so that the double-headed screw 5 and the first nut 4 are matched.

[0023] The other end of the double-ended screw 5 is sleeved with a fastener 1, which is a tight hoop for connecting the pipe 10 and the double-ended screw 5. The fastener 1 is sleeved on the double-ended screw 5 and can rotate around. At the same time, the fastener 1 adopts an embracing manner. To a certain extent, the position of the fastener 1 on the bidirectional screw 5 can be fine-tuned, which is conducive to the connection of the pipe 10.

[0024] Combination Figure 2 and Figure 3 As shown, the fastener 1 is a two-petal structure, which embraces the pipe fitting 10 for fixation, and the two petals are rotationally connected, one of which is sleeved on the double-headed screw 5, and the other end of the double-headed screw 5 is threadedly matched with a second nut 6. When the fastener 1 is sleeved on the end of the double-headed screw 5, the second nut 6 is used to fit on the double-headed screw 5 to fix the fastener 1.

[0025] A bolt 7 is inserted into one of the petals, and the bolt 7 passes upward to the end of the other petal, and a third nut 9 is threadedly provided on the bolt 7. The pipe fitting 10 is placed on one of the petals, and then the other petal is rotated to embrace the pipe fitting 10, and then the bolt 7 and the third nut 9 are used to fix it, that is, the third nut 9 is fixed, and the end of the third nut 9 is against the other petal to achieve a close fit of the two-petal structure.

[0026] A spring washer 8 is arranged below the third nut 9 to provide pre-tightening for the third nut 9 and improve the anti-vibration and anti-loosening capability of the device.

[0027] One end of the fastener 2 is provided with a regular hexagonal groove, and the first nut 4 fits exactly in the groove, that is, when the stud screw 5 is rotated, the first nut 4 can be prevented from rotating simultaneously with the stud screw 5.

[0028] The usage of this embodiment is as follows: first, the fastener 2 is placed in the building formwork and then poured, and the wall 11 is waited for to solidify. Then, the double-headed screw 7 is inserted into the interior of the fastener 2 and threadedly connected with the preset first nut 4. Then, the fastener 1 is sleeved on the other end of the double-headed screw and fixed with the second nut 6. Finally, the pipe fitting 10 is fixed to the fastener 1 through the screw 7 and the third nut 9.

[0029] This usage method has the advantage of easy disassembly, and the first nut 4 is also easy to collect and reuse. Secondly, the fastener 2 has a through hole reserved on the wall 10, which can be used as a wiring channel for cables if necessary. If not needed, since the through hole set by the fastener 2 is small, it is also convenient to block. Example

[0030] The difference between this embodiment and the first embodiment is that: Figure 2 As shown, a tail sleeve 3 is provided at the end of the fastener 2, and the tail sleeve 3 covers the first nut 4. The function of the tail sleeve 3 is similar to that of a plug, and is used to seal one end of the fastener 2 to prevent concrete from entering the interior of the fastener 2 during the pouring process, resulting in the inability of the double-headed screw 5 to be threadedly connected with the first screw 4. In addition, a certain axial space is provided inside the tail sleeve 3 to facilitate the double-headed screw 5 to rotate and extend to the interior of the tail sleeve 3, thereby achieving a full connection between the double-headed screw 5 and the first nut 4, and limiting the axial movement of the first nut 4 under the cooperation of the tail sleeve 3 and the fastener 2.

[0031] The usage of this embodiment is as follows: the first bolt 4 is placed at the end of the fastener 2 in advance, and then the tail sleeve 3 is installed at the end of the fastener 2 to resist the first bolt 4, and then the fastener 2 is placed in the building formwork. After pouring, the tail sleeve 3 is located inside the wall 10, and then the double-headed screw 5 is connected and fixed. The following method is the same as that of the first embodiment, which will not be repeated here.

[0032] Furthermore, the first screw 4 is eliminated, and a stepped hole is provided inside the fastener 2. The diameter of the first stepped hole is larger than the diameter of the second stepped hole. The first stepped hole is used to insert the double-headed screw 5. The inner wall of the second stepped hole is tapped so that the thread there can cooperate with the double-headed screw 5. The setting of the tail sleeve 3 remains unchanged, which is conducive to the tapping process.

[0033] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
