Description

Technical Field

[0001] This utility model relates to the field of EPS lines, and more specifically, to an easily fixed exterior wall EPS line. Background Technology

[0002] EPS (Expanded Polystyrene) exterior wall trim is a type of architectural decorative component made of expanded polystyrene (EPS) material, primarily used for decorative parts of building facades such as cornices, waistlines, and window frames. It features lightweight construction (only 1 / 6 the weight of traditional GRC materials), a wide variety of shapes, and convenient installation, while also possessing thermal insulation properties, allowing for seamless integration with building exterior wall insulation systems. Through special surface treatments (such as polymer mortar coatings), EPS trim exhibits good fire resistance, waterproofing, and impact resistance, meeting both aesthetic requirements and improving overall energy efficiency. Compared to traditional stone or concrete components, EPS trim offers faster installation, lower costs, and effectively avoids thermal bridging, making it an ideal choice for modern architectural decoration. Current installation methods for EPS exterior wall trim require first installing steel nails on the wall, then applying mortar to the back of the EPS trim, and finally attaching the trim to the exterior wall while the steel nails are inserted into the trim for fixation.

[0003] Existing EPS moldings rely on steel nails for temporary mechanical fixation before the mortar hardens during installation. However, the fixation effect is not good because the surface of the steel nails is relatively smooth. Therefore, we have made improvements and proposed an easy-to-fix EPS molding for exterior walls. Utility Model Content

[0004] To address the problems raised in the background art, this utility model provides the following technical solution: Convenient and easy-to-fix EPS moldings for exterior walls can improve the above-mentioned problems.

[0005] The present invention is as follows: The device includes an outer shell, a foam core inside the outer shell, a first horizontal support frame inside the foam core, a first vertical support frame and a second vertical support frame welded to the first horizontal support frame, a guide mechanism inside the foam core, a steel nail inserted into the bottom of the foam core, a slot on the steel nail, and a spring piece fixedly connected to the inner wall of the outer shell, the spring piece cooperating with the slot.

[0006] As a preferred technical solution of this utility model, the first vertical support frame and the second vertical support frame are welded with the same second horizontal support frame.

[0007] As a preferred technical solution of this utility model, the guiding mechanism includes a first hollow ring and a second hollow ring. The first hollow ring is bonded to the bottom of the foam core, and the second hollow ring is bonded to the inside of the foam core. The first hollow ring and the second hollow ring correspond to each other.

[0008] As a preferred technical solution of this utility model, the spring sheet has an arc surface.

[0009] As a preferred technical solution of this utility model, one end of the steel nail is provided with a nail tip, and the other end of the steel nail is provided with a nail head.

[0010] As a preferred technical solution of this utility model, a groove is provided at the bottom of the foam core.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In the solution of this utility model: 1. By inserting the head end of a steel nail into a foam core, the nail head first passes through the first hollow ring and then through the second hollow ring. During this process, the nail head will contact the spring clip, causing the spring clip to undergo elastic deformation until it is completely locked into the slot. This not only achieves the function of temporary mechanical fixation, but also forms a mechanical interlock between the spring clip and the slot, which greatly improves the pull-out resistance and solves the problem of poor fixation effect in the existing technology due to the relatively smooth surface of the steel nail. 2. By welding the first horizontal support frame, the second horizontal support frame, the first vertical support frame, and the second vertical support frame together and then bonding them into the foam core, the strength of this EPS line can be increased. 3. By applying mortar to the back of the foam core and filling the groove with mortar, the contact area between the mortar and the foam core can be increased, making the bond more secure after installation.

[0019] like Figure 1-8 As shown, this embodiment proposes a convenient and fixed external wall EPS line, including an outer shell 1, a foam core 2 inside the outer shell 1, a first horizontal support frame 3 inside the foam core 2, a first vertical support frame 4 and a second vertical support frame 5 welded to the first horizontal support frame 3 respectively, the first horizontal support frame 3, the second horizontal support frame 6, the first vertical support frame 4 and the second vertical support frame 5 inside the foam core 2 are welded together to form a reinforcing frame, making the EPS line stronger; a guide mechanism is provided inside the foam core 2, the guide mechanism is used to assist the insertion of steel nails 7; a steel nail 7 is inserted into the bottom of the foam core 2, the steel nail 7 has a slot 12, and a spring piece 10 is fixedly connected to the inner cavity side wall of the outer shell 1, the spring piece 10 cooperates with the slot 12, and a mechanical interlock is formed between the spring piece 10 and the slot 12, which greatly improves the pull-out resistance.

[0020] The same second horizontal support frame 6 is welded to the first vertical support frame 4 and the second vertical support frame 5. The first horizontal support frame 3, the second horizontal support frame 6, the first vertical support frame 4 and the second vertical support frame 5 inside the foam core 2 are welded together to form a reinforcing frame, making the EPS line stronger.

[0021] The guiding mechanism includes a first hollow ring 8 and a second hollow ring 9. The first hollow ring 8 is bonded to the bottom of the foam core 2, and the second hollow ring 9 is bonded inside the foam core 2, so that the end of the steel nail 7 with the nail head 14 is inserted into the foam core 2. During the insertion process, the nail head 14 first passes through the first hollow ring 8 and then through the second hollow ring 9. The first hollow ring 8 and the second hollow ring 9 correspond to each other.

[0022] An arc surface 11 is provided on the spring piece 10 so that when the steel nail 7 touches the spring piece 10, the spring piece 10 can undergo elastic deformation.

[0023] A nail tip 13 is provided at one end of the steel nail 7. The end of the steel nail 7 with the nail tip 13 is nailed to the wall. The other end of the steel nail 7 is provided with a nail head 14, so that the end of the steel nail 7 with the nail head 14 is inserted into the foam core 2.

[0024] The bottom of the foam core 2 has a groove 15. Mortar is applied to the back of the foam core 2 so that the mortar also fills the groove 15. This increases the contact area between the mortar and the foam core 2, which makes the bonding more secure after installation.

[0025] Specifically, when using this convenient and fixed exterior wall EPS line: first, nail the end of the steel nail 7 with the nail tip 13 to the wall, then apply mortar to the back of the foam core 2, so that the mortar also fills the groove 15. This increases the contact area between the mortar and the foam core 2, making the bond more secure after installation. Next, install the EPS line (outer shell 1 and foam core 2) on the wall, so that the end of the steel nail 7 with the nail head 14 is inserted into the foam core 2. During the insertion process, the nail head 14 first passes through the first hollow ring 8 and then through the second hollow ring 9. During this process, the nail head 14 will contact the spring piece 10, causing the spring piece 10 to undergo elastic deformation until it is completely inserted into the slot 12. This not only plays a role in temporary mechanical fixation, but also forms a mechanical interlock between the spring piece 10 and the slot 12, which greatly improves the pull-out resistance. The first horizontal support frame 3, the second horizontal support frame 6, the first vertical support frame 4 and the second vertical support frame 5 inside the foam core 2 are welded together to form a reinforcing frame, making the EPS line stronger.

[0026] All technical features in this embodiment can be freely combined according to actual needs.
