Description

Technical Field

[0001] This utility model relates to the field of line fixing technology, and in particular to an EPS line fixing component. Background Technology

[0002] EPS lines refer to strips or lines of polystyrene foam plastic. In the field of building exterior wall decoration, this material is widely used because of its advantages of being lightweight, easy to shape, and having good thermal insulation properties. EPS line fasteners are devices used to fix EPS lines to the exterior facade of buildings or other substrates to prevent them from falling off. Their main structure includes anchoring discs, nails or screws, expansion sleeves, and nuts.

[0003] In practical use, the anchoring disc of traditional anchors is a flat plate of uniform thickness, making invisible contact with the EPS line. When the EPS line is subjected to external forces, the stress concentrates near the anchoring disc. When this stress accumulates to a certain extent, it exceeds the compressive strength limit of the EPS line material, causing the EPS line to crack and fall off. At the same time, the EPS line will undergo significant thermal expansion and contraction and deformation under large temperature changes. The transmission anchoring disc is made of metal or engineering plastic without displacement buffer design. When the deformation reaches a certain level, the EPS line will also crack and fall off, damaging the aesthetics and integrity of the building surface and endangering the safety of surrounding personnel. Under current technology, attempts have been made to solve the above problems by increasing the diameter of the anchoring disc or using soft gaskets. However, the former increases the inherent weight of the anchor, increases its load, and cannot adapt to EPS lines of different sizes. The latter's material properties change over time, hardening and deforming, and it can no longer play a buffering role. Neither of these methods fundamentally solves the problems of stress concentration and thermal deformation expansion cracking. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 3This utility model provides an embodiment of an EPS (Expanded Polystyrene) strip fixing component, comprising an EPS strip 1. Multiple anchor bolt mechanisms 2 are threadedly connected to the front bottom of the EPS strip 1, each anchor bolt mechanism 2 serving to fix the EPS strip 1. A protective mechanism 3 is installed on the front side of each anchor bolt mechanism 2, providing protection and assisting in maintaining the anchor bolt's firmness. Each anchor bolt mechanism 2 includes a bolt body 201, threadedly connected to the front bottom of the EPS strip 1, and a hexagonal nut 208 threadedly connected to the front end of the bolt body 201. The anchor bolt 208 is a crucial component for securing the entire anchor bolt to the wall 4. A front washer 202 is located on the rear side of the hexagonal nut 208. The front washer 202 is slidably connected to the front end of the outer wall of the bolt body 201, contacting the front surface of the EPS material for fixation. An expansion pin 205 is fixedly connected to the rear end of the bolt body 201, generating the necessary friction for fixation. A rear washer 203 is slidably connected to the middle outer wall of the bolt body 201. A sleeve 204 is threadedly connected to the rear outer wall of the bolt body 201, cooperating with the expansion pin 205 to allow the bolt body 201 to... Fixed to the wall 4, the bolt body 201 has a threaded tooth 207 at its front end, which engages with the threaded groove 9 on the inner wall of the hexagonal nut 208. A buffer assembly 206 is installed in the middle of the bolt body 201. The buffer assembly 206 includes a disc spring 2061, which is fixedly connected to the rear side of the front washer 202. The disc spring 2061 is slidably connected to the bolt body 201 to absorb some stress and prevent excessive stress concentration. A soft buffer pad 2062 is fixedly connected to the front side of the rear washer 203, so that the EPS line 1 can deform to a certain extent. Multiple plastic claws 2063 are fixedly connected to the outer wall of the rear gasket 203 to grip and further fix the EPS line 1. Anti-slip texture 6 is fixedly connected to the front side of the rear gasket 203 to increase friction and improve the fixing effect. The inner wall of the hexagonal nut 208 is provided with a threaded groove 9, which allows it to rotate and move at the front end of 201. The middle of the bolt body 201 is fixedly connected with a spiral limiting tooth 7. The inner wall of the sleeve 204 is provided with a toothed groove 8. The spiral limiting tooth 7 and the toothed groove 8 mesh to ensure that the sleeve 204 will not slide back and forth on the surface of 201.

[0033] Specifically, during installation, use equipment to drill anchor holes at appropriate locations on wall 4 according to pre-planned points. The diameter and depth of the anchor holes should match the bolt body 201 to ensure stable installation. After drilling, insert the bolt body 201 into the anchor hole and rotate the hexagonal nut 208. The hexagonal nut 208 is threadedly connected to the bolt body 201. During rotation, the bolt body 201 moves spirally outward axially. The diameter of the expansion pin 205 at the front end of the bolt body 201 is larger than that of the sleeve 204. As the bolt 201 moves forward, the expansion pin 205 gradually expands the sleeve 204. The sleeve 204 expands outward under pressure, tightly fitting against the wall of the hole 4, generating strong friction to firmly fix the bolt 201 in the wall 4. After fixing the bolt 201, use a disassembly tool to remove the hexagonal nut 208, the front washer 202, and the disc spring 2061 from the front of the bolt 201 in sequence. Place the EPS line 1 on the rear washer 203 accordingly, and adjust the position and angle of the EPS line 1. To ensure installation accuracy, the disassembled hexagonal nut 208, front washer 202, and disc spring 2061 are reinstalled onto the front of the bolt body 201. By tightening the hexagonal nut 208, all components are tightly fitted, completing the initial installation of the EPS line 1. When subjected to pressure, the disc spring 2061 will deform accordingly according to the actual force, using its own elastic properties to absorb the stress generated on the EPS line 1 during installation, avoiding stress concentration that could lead to tearing and damage to the EPS line 1. The plastic claw 2063 is embedded inside the back side of the EPS line 1 during installation, limiting and fixing the EPS line 1 in multiple directions, preventing abnormal displacement during subsequent use, and avoiding damage to the line material itself due to displacement. The soft buffer pad 2062 is made of soft material and plays a buffering role during installation and use. Because it is located inside the mounting surface, it is not easily affected by external environmental factors and can stably perform its buffering function for a long time.

[0034] Reference Figure 4 and Figure 5The protective mechanism 3 includes a conical shield 301, which is installed on the front side of the hexagonal nut 208. A barrel-shaped protective shell 302 is slidably connected to the rear outer wall of the conical shield 301. A connecting short post 304 is fixedly connected inside the barrel-shaped protective shell 302 to connect the barrel-shaped protective shell 302 and the fixing ring 3061. Two sliding grooves 303 are formed on the rear outer wall of the conical shield 301. A connecting short post 304 is slidably connected inside each of the two sliding grooves 303. The connecting short post 304 can slide back and forth in them. The barrel-shaped protective shell 302 is slidably connected to the rear outer wall of the conical shield 301 through the two connecting short posts 304. A ratchet disc 305 is fixedly connected to the rear outer wall of the hexagonal nut 208. The inner wall of the barrel-shaped protective shell 302 is fixedly connected to... A locking assembly 306 is provided to prevent the protective mechanism 3 from accidentally falling off. The locking assembly 306 includes a retaining ring 3061, which is fixedly connected to the ends of two connecting short posts 304 and connected to the barrel-shaped protective shell 302 and can move synchronously. The top and bottom inner walls of the retaining ring 3061 are fixedly connected to a rotating base 3062. A pawl 3063 is rotatably connected to the middle of the rotating base 3062. The pawl 3063 is engaged with a ratchet disc 305. A rotating shaft 5 is rotatably connected to the middle of the rotating base 3062. The pawl 3063 is fixedly connected to the outside of the rotating shaft 5, so that the pawl 3063 can rotate and work inside the rotating base 3062. The pawl 3063 is rotatably connected to the middle of the rotating base 3062 through the rotating shaft 5.

[0035] Specifically, align the conical shield 301 with the front end of the tether body 201 and press it against the front end of the tether body 201 to ensure a tight connection. After installing the conical shield 301, hold the barrel-shaped protective shell 302 and push it backward along the axis of the tether body 201. The barrel-shaped protective shell 302 completely encloses the exposed part of the tether body 201, forming a protective barrier that effectively blocks external debris, dust, moisture, etc., from corroding the tether body 201 and preventing damage from the external environment. The barrel-shaped protective shell 302 has a pawl 3063 on its inner side, and the ratchet disc 305 is fixed at a specific position on the tether body 201. As the barrel-shaped protective shell 302 is pushed backward, the pawl 3063 gradually approaches the ratchet disc 305 until the two are fully engaged. The conical shield 301 is rotated. The conical shield 301 is connected to the fixed ring 3061 through the connecting short column 304. The fixed ring 3061 is fixedly connected to the rotating base 3062. When the conical shield 301 rotates, it will drive the fixed ring 3061 and the rotating base 3062 to rotate synchronously. Since the pawl 3063 is installed on the rotating base 3062, it also rotates together. The meshing characteristics of the pawl 3063 and the ratchet disc 305 make the conical shield 301 only rotate in one direction. Even when subjected to external forces such as vibration, the meshing of the pawl 3063 and the ratchet disc 305 can prevent the conical shield 301 from rotating in the opposite direction, thereby effectively preventing the conical shield 301 from accidentally falling off due to vibration.

[0036] Reference Figure 1 and Figure 2 A wall 4 is provided on the back side of EPS line 1. The wall 4 is the attachment point of EPS line 1. It is installed on its surface. The bolt 201 is threadedly connected to the wall 4. The bolt is fixed inside the EPS line 1 and the wall 4 to achieve the purpose of fixing the two.

[0037] Specifically, an internal threaded hole that matches the external thread of the bolt 201 is pre-drilled on the wall 4. The diameter and pitch of the internal threaded hole are consistent with the parameters of the external thread of the bolt 201. By aligning the bolt 201 with the internal threaded hole on the wall 4, the bolt 201 can be screwed into the internal threaded hole of the wall 4. As the number of rotations increases, the connection between the two becomes tighter and tighter until the bolt 201 reaches the predetermined installation depth, completing the threaded connection with the wall 4 and realizing the basic step of initially fixing the EPS line 1 to the wall 4.

[0038] Working principle: During installation, first drill anchor holes at appropriate locations on wall 4, then insert the bolt 201 and rotate the hexagonal nut 208. The bolt 201 then spirals outwards. Since the diameter of the expansion pin 205 is larger than that of the sleeve 204, it will expand the sleeve 204 during this forward movement. The expansion of the sleeve 204 will generate strong friction with the wall 4. After fixing the bolt 201, remove the hexagonal nut 208, front washer 202, and disc spring 2061 from the front of the bolt 201. Then, install the EPS line 1 on the rear washer 203. Finally, reinstall the hexagonal nut 208, front washer 202, and disc spring 2061 to complete the initial installation of the EPS line 1. After installation, the disc spring 2061 will adjust according to the actual situation. The system absorbs stress generated on the EPS line 1 during installation to prevent tearing. Multiple soft buffer pads 2062 are embedded inside the back side of the EPS line 1, fixing its position in multiple directions to prevent abnormal displacement that could damage the line material itself. At the same time, the soft material of the plastic claws 2063 also plays a buffering role. Because they are located inside the mounting surface, they are not easily weathered by the external environment and can function for a longer period of time. This mechanism can change the rigid connection into an elastic connection while fixing the EPS line 1, preventing material damage. It also allows the EPS line 1 to deform to a certain extent due to temperature changes without directly contacting the rigid fasteners, thus solving the problem that existing technologies have not fundamentally solved the issues of stress concentration and thermal deformation expansion cracking.

[0039] The conical guard 301 is installed at the front end of the bolt body 201, and then the barrel-shaped protective shell 302 is pushed backward. During the movement of the barrel-shaped protective shell 302, the exposed part of the bolt body 201 is protected, preventing the bolt body from being damaged by the external environment. At the same time, during the movement of the barrel-shaped protective shell 302, the pawl 3063 is engaged with the ratchet disc 305. At this time, the conical guard 301 is rotated, which drives the fixed ring 3061, the rotating base 3062 and the pawl 3063 on it to rotate. The pawl 3063 makes the conical guard 301 rotate only in one direction, preventing accidental dislodgement due to vibration.
