Description

Technical Field

[0001] This application relates to the field of wall tying technology, and more particularly to tying components. Background Technology

[0002] Double-layer hollow sandwich insulated composite fair-faced brick wall masonry is a building wall structure. It is formed by adding insulation material to the outside of the main structure and secondary structure of the building and then building fair-faced brick wall to form a double-layer hollow sandwich insulated composite fair-faced brick wall masonry, thereby improving the overall insulation performance of the building wall.

[0003] In existing technologies, after the insulation material is pasted on the outside of the main structure and the secondary structure, insulation tie-ins are required to fix the insulation material to the outside of the main structure and the secondary structure. At the same time, the surface of the insulation material needs to be pre-drilled to allow for the tie-ins of the exposed brick wall when it is built on the outside of the insulation material. In this way, the integrity between the main structure, the secondary structure, the insulation material and the exposed brick wall is improved through the insulation tie-ins and the exposed brick tie-ins.

[0004] Both thermal insulation tie-ins and exposed brick tie-ins require separate tie-structure components for fixation, resulting in a large number of tie-in points and reduced construction efficiency. Furthermore, the need to penetrate the insulation material during thermal insulation tie-ins and the requirement to pre-drill holes in the insulation material before tying exposed bricks both damage the insulation material, leading to an irreversible decrease in its insulation performance. Utility Model Content

[0005] To address the aforementioned technical problems and achieve at least one advantage of this application, this application provides a tucking assembly, wherein the tucking assembly comprises:

[0006] A fixed body includes a through-part, at least two expansion parts, and a stabilizing part. The through-part penetrates the insulation body and has a through-channel along its axial direction. At least two expansion parts are connected to the through-part at one end in a deformable and partially relatively far apart manner, and the at least two expansion parts are evenly distributed around the axis of the through-part. The at least two expansion parts each have a tie hole inserted into the surface of the wall body. The at least two expansion parts enclose a top tension space that communicates with the through-channel. The inner diameter of the top tension space gradually decreases from the end near the through-part to the end away from the through-part. The at least two expansion parts each extend partially away from the axis of the through-part to form several protrusions. The stabilizing part is fitted onto the end of the through-part away from the expansion part and remains attached to the insulation body.

[0007] An insert is coaxial with the passageway and passes through the passageway and is inserted into the top tension space while remaining attached to the inner wall of the top tension space. As the insert passes through the passageway and is inserted into the top tension space, at least two of the expansion portions are separated by the insert and each of the protrusions is inserted into the inner wall of the tie hole. The end of the insert that does not pass through the passageway is positioned in the mortar joint between adjacent bricks.

[0008] According to one embodiment of this application, the end portion of the insert that does not pass through the through-channel extends radially to form a protruding structure.

[0009] According to one embodiment of this application, the top tension space is implemented as a cone shape.

[0010] According to one embodiment of this application, each of the protrusions is implemented as barbs.

[0011] According to one embodiment of this application, the stabilizing part and the crossing part are integrally formed.

[0012] According to one embodiment of this application, the stabilizing part is kept threadedly connected to the through part in a manner that allows it to move along the axial direction of the through part.

[0013] According to one embodiment of this application, at least two ends of the expansion portion away from the through portion converge in the direction of extension of the axis of the through portion to form a converging end, and the surfaces of the at least two converging ends each have an inclined surface, and the inclined surfaces of the at least two converging ends together form a cone shape.

[0014] According to one embodiment of this application, the length of the through portion, at least two of the expansion portions, and the stabilizing portion along the axial direction of the through portion is less than the length of the insert along the axial direction. The insert forms a through portion at the end that is inserted into the top tension space and away from the stabilizing portion. The through portion is used to insert into the bottom wall of the tie hole of the wall body.

[0015] According to one embodiment of this application, the fixing body further includes a tapered portion connected to the ends of at least two of the expansion portions away from the through portion, the tapered portion having a gradually decreasing radial dimension from the end near the expansion portion to the end away from the expansion portion to form a tapered surface.

[0016] According to one embodiment of this application, the insert is implemented as a threaded steel bar. Attached Figure Description

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0025] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0026] refer to Figures 1 to 6 A preferred embodiment of the zip-up assembly according to this application will be described in detail below, wherein the zip-up assembly includes a fixing body 10 and an insert 20.

[0027] Specifically, the fixing body 10 includes a through portion 11, at least two expansion portions 12, and a stabilizing portion 13. The through portion 11 penetrates an insulation body 92. A through channel 1101 is formed in the through portion 11 along its axial direction. At least two expansion portions 12 are respectively connected to the through portion 11 at one end in a deformable and partially relatively far apart manner, and the at least two expansion portions 12 are evenly distributed around the axial direction of the through portion 11. The at least two expansion portions 12 each retain a tie hole inserted into the surface of a wall body 91, and enclose a top tension space 101 that communicates with the through channel 1101 between the at least two expansion portions 12. The inner diameter of the top tension space 101 gradually decreases from the end near the through portion 11 to the end away from the through portion 11. The at least two expansion portions 12 each extend partially away from the axis of the through portion 11 to form a plurality of protrusions 121. The stabilizing part 13 is sleeved on the end of the passing part 11 away from the expanding part 12, and the stabilizing part 13 remains attached to the insulation body 92.

[0028] The insert 20 is coaxial with the through-channel 1101, and the insert 20 passes through the through-channel 1101 and is inserted into the top tension space 101 while remaining attached to the inner wall of the top tension space 101. As the insert 20 continuously passes through the through-channel 1101 and is inserted into the top tension space 101, at least two of the expansion portions 12 are pushed apart and moved away from each other, and each of the protrusions 121 is respectively attached to and inserted into the inner wall of the tie hole. The end of the insert 20 that does not pass through the through-channel 1101 is provided in the mortar joint between adjacent bricks 93.

[0029] It should be noted that, since at least two of the expansion portions 12 have several protrusions 121 respectively attached to and inserted into the inner wall of the tie hole, the expansion portion 12 of the fixing body 10 is fixed to the tie hole of the wall body 91, and the through portion 11 of the fixing body 10 is stably maintained through the insulation body 92. Thus, the stabilizing portion 13 provided on the expansion portion 12 will be stably attached to the insulation body 92, thereby making the insulation body 92 stably tied and fixed.

[0030] Meanwhile, since the insert 20 inserted into the top tension space 101 remains attached to the inner wall of the top tension space 101, and the portion of the insert 20 inserted into the top tension space 101 is fixed by the compression of at least two expansion portions 12, after the end of the insert 20 that does not pass through the through channel 1101 is placed in the mortar joint between adjacent bricks 93, the brick wall formed by the bricks 93 will be stably tied and fixed.

[0031] It is worth mentioning that, compared to separately binding the insulation body 92 to the wall body 91 and separately binding the brick wall formed by the bricks 93 to the wall body 91 by pre-drilling holes on the surface of the insulation body 92, the binding assembly in this application can not only bind and fix the insulation body 92, but also simultaneously bind and fix the brick wall formed by the bricks 93. Therefore, the binding assembly in this application can reduce damage to the insulation body 92 during use, thereby reducing the damage to the insulation effect of the insulation body 92.

[0032] Meanwhile, compared to separately binding the insulation body 92 to the wall body 91 and separately binding the brick wall formed by the bricks 93 to the wall body 91 by pre-drilling holes on the surface of the insulation body 92, the binding assembly in this application can reduce the material input when binding the insulation body 92 and the bricks 93, and improve construction efficiency.

[0033] Preferably, the end portion of the insert 20 that does not pass through the through-channel 1101 extends radially to form a protruding structure 21. This increases the contact area between the insert 20 and the mortar joint between the adjacent bricks 93 after the end portion of the insert 20 that does not pass through the through-channel 1101 is positioned in the mortar joint between the adjacent bricks 93. This improves the stability of the end portion of the insert 20 that does not pass through the through-channel 1101 remaining in the mortar joint between the adjacent bricks 93 and reduces the probability of the insert 20 detaching from the mortar joint between the adjacent bricks 93.

[0034] Furthermore, the insert 20 extends along the axial direction to form a protruding structure 21, thereby increasing the friction between the insert 20 and the inner wall of the top tension space 101 and the inner wall of the through channel 1101, and reducing the possibility that the insert 20 will detach from the top tension space 101 and the through channel 1101 along the axial direction.

[0035] As an example, the insert 20 is implemented to include threaded steel.

[0036] In this embodiment, the top tension space 101 is implemented as a cone shape. That is, the inner wall of the top tension space 101 formed by each of the expansion portions 12 is generally cone-shaped, so as to increase the contact area between the at least two expansion portions 12 and the insertion member 20 when the insertion member 20 is continuously inserted into the top tension space 101 and pushes the at least two expansion portions 12 apart to move away from each other, thereby improving the stability when the at least two expansion portions 12 are pushed apart.

[0037] Preferably, each of the protrusions 121 is implemented as a barb, so that when each of the protrusions 121 is attached to and inserted into the inner wall of the tie hole, it is easy for each of the protrusions 121 to be inserted into the inner wall of the tie hole, thereby improving the stability of each of the protrusions 121 when it is inserted into the inner wall of the tie hole, preventing at least two of the expansion portions 12 from detaching from the tie hole along the axial direction, thereby improving the stability of the tie assembly during use, so that the tie assembly can maintain a stable tie to fix the insulation body 92, and simultaneously maintain a stable tie to fix the brick wall formed by the bricks 93.

[0038] In one embodiment, the stabilizing portion 13 and the passing portion 11 are integrally formed, that is, the end of the passing portion 11 away from the expansion portion 12 extends radially to form the stabilizing portion 13 in a manner that keeps it attached to the surface of the insulation body 92, so that the passing portion 11 is attached to the insulation body 92 through the stabilizing portion 13, preventing the passing portion 11 from excessively passing through the insulation body 92, while maintaining a stable connection and fixing of the insulation body 92.

[0039] In another modified embodiment, the stabilizing part 13 is threadedly connected to the through part 11 in a manner that allows it to move along the axial direction of the through part 11. When the expansion part 12 is inserted into the tie hole, and the depth of the tie hole is insufficient to keep the stabilizing part 13 attached to the insulation body 92, the stabilizing part 13 is moved along the axial direction of the through part 11 to keep the stabilizing part 13 attached to the insulation body 92, thereby stabilizing and fixing the insulation body 92 and improving the versatility of the tie assembly.

[0040] To enable those skilled in the art to understand this application, at least one embodiment of this application is described only as an example of the stabilizing part 13 and the crossing part 11 being integrally formed.

[0041] like Figures 1 to 3 As shown, in this embodiment, the ends of at least two expansion portions 12 that are away from the through portion 11 converge in the direction extending from the axis of the through portion 11 to form a converging end 122. The surfaces of the at least two converging ends 122 each have an inclined surface 1221. The inclined surfaces 1221 of the at least two converging ends 122 together form a cone shape, so that during the insertion of the at least two expansion portions 12 into the tie hole of the wall body 91, the inclined surfaces 1221 of the converging at least two converging ends 122 guide the at least two expansion portions 12 to be easily and stably inserted into the tie hole as a whole, and prevents displacement.

[0042] As an example, such as Figure 3As shown, when the insert 20 is continuously inserted into the top tension space 101, and the insert 20 pushes at least two of the expansion portions 12 apart to move away from each other, the aggregation ends 122 of at least two of the expansion portions 12 will move away from each other to adhere to the inner wall of the tie hole.

[0043] Preferably, the length of the through portion 11, at least two of the expansion portions 12, and the stabilizing portion 13 along the axial direction of the through portion 11 is less than the length of the insert 20 along the axial direction. The insert 20 forms a through portion 22 at the end that is inserted into the top tension space 101 and away from the stabilizing portion 13, the through portion 22 being used to insert into the bottom wall of the tie hole of the wall body 91.

[0044] The insertion part 22 is inserted into the bottom wall of the tie hole to improve the stability of the insert 20 within the top tension space 101 and the through channel 1101. This allows the tie assembly to stably tie and fix the insulation body 92 while simultaneously maintaining a stable tie and fixation of the brick wall formed by the bricks 93.

[0045] like Figures 4 to 6 As shown, in another modified embodiment, the fixing body 10 further includes a conical portion 14 connected to the ends of at least two expansion portions 12 away from the through portion 11. The radial dimension of the conical portion 14 gradually decreases from the end near the expansion portion 12 to the end away from the expansion portion 12 to form a conical surface 141. This allows the at least two expansion portions 12 to be easily and stably inserted into the tie hole of the wall body 91 by first inserting the conical portion 14 into the tie hole, and by the guidance of the conical surface 141, preventing displacement.

[0046] As an example, such as Figure 6 As shown, when the insert 20 is continuously inserted into the top tension space 101, at least the portions of the expansion 12 along the extension direction will move away from each other to secure the protrusions 121 to the inner wall of the tie hole. Simultaneously, under the constraint of the tapered portion 14, the portion of the insert 20 inserted into the top tension space 101 will be stably attached to at least two of the expansion portions 12 and fixed in place.

[0047] Preferably, the fixing body 10 is made of, but not limited to, metal and plastic. When the fixing body 10 is made of metal, the protrusion 121 will easily insert into the tie hole of the wall body 91 for fixation.

The advantages of this application have been fully and effectively implemented.
