Description

Technical Field

[0001] This utility model relates to the field of external wall casting strip technology, specifically a novel deep groove model for external wall casting strips. Background Technology

[0002] In traditional exterior wall casting strip construction, standard casting strip models are typically used for deep wall trenching. However, existing casting strip construction techniques have many shortcomings, particularly in terms of construction complexity and subsequent cracking issues. With the development of the construction industry, especially the rise of high-rise buildings and large-scale residential projects, the quality problems of deep exterior wall trenches are becoming increasingly prominent.

[0003] Existing cast-in-place strip construction techniques are quite complex, involving multiple steps and material coordination. Workers need to perform precise operations based on the specific wall structure and the shape of the deep groove, increasing the construction difficulty. During construction, it is often difficult for construction personnel to ensure perfect execution of every detail, resulting in uneven construction or poor material adhesion in the deep groove section, thus affecting the overall aesthetics and quality of the exterior wall.

[0004] Traditional exterior wall casting strips often face a significant risk of cracking during long-term use. Due to the difference in thermal expansion coefficients between the wall material and the casting strip, the wall is affected by temperature changes during daily use, making the casting strip area prone to cracking. In addition, the deep grooves in the exterior wall, as structural turning points, are easily affected by external environmental factors (such as wind pressure and rainwater infiltration), further exacerbating the formation of cracks.

[0005] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a new type of deep groove model for external wall casting. Utility Model Content

[0006] The purpose of this invention is to provide a novel deep groove model for external wall casting to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A novel technical solution for casting deep grooves in exterior walls includes:

[0009] The main body of the model has a through-hole inside for filling with casting material;

[0010] The upper partition strip is set at the top of the main body of the model and is used to define the boundary of the casting strip;

[0011] An extension section is connected to the deep groove turning points on both sides of the model body. The extension section is provided with an extension port and communicates with the model port.

[0012] An arc-shaped concave surface is formed on the outer side of the extension to fit the wall.

[0013] As a preferred technical solution, the width of the model opening and the expansion opening is 5mm, which is used to control the forming thickness of the casting strip.

[0014] As a preferred technical solution, the surfaces of the model body and the extension are provided with an anti-stick coating to further optimize the demolding effect.

[0015] As a preferred technical solution, the main body and extension of the model are made of PVC, and the overall length is 2 meters and the cross-sectional dimensions are 50mm×15mm.

[0016] As a preferred technical solution, the cross-sectional shape of the model opening and the expansion opening is trapezoidal or rectangular to adapt to different decorative effect requirements.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention relates to a novel deep-groove model for exterior wall casting strips. The designed main body and extension structure significantly improve the construction quality and efficiency of deep-groove exterior walls. The design of the model's opening and the extension opening ensures uniform filling of the casting material, avoiding problems such as uneven construction and material misalignment. Simultaneously, the curved concave surface allows the model to better adapt to the wall structure, reducing construction difficulty and improving construction accuracy. Furthermore, the application of an anti-stick coating further optimizes the demolding effect, reducing adhesion between the model and the casting strip, and improving construction efficiency.

[0022] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0023] like Figure 1 , Figure 2 As shown, this utility model provides a novel deep groove model for external wall casting strips: it includes a model body 1, which is the core part of the entire deep groove model, and has a through-hole 11 inside for filling with casting material. The size and shape of the model body 1 are designed according to actual construction requirements to ensure the structural strength and appearance of the casting strip.

[0024] The upper spacer 12 is set at the top of the model body 1. Its main function is to limit the boundary of the casting strip and ensure that the casting material does not overflow the predetermined area when filling. At the same time, the upper spacer 12 also plays a role in strengthening the top of the model body 1.

[0025] The extension section 2 is connected to the deep groove turning points on both sides of the model body 1. It has an extension opening 21 and communicates with the model opening 11. The design of the extension section 2 allows the casting strip to be reinforced in the deep groove, while the setting of the extension opening 21 ensures that the casting material can be evenly filled into every corner of the deep groove.

[0026] An arc-shaped concave surface 22 is formed on the outer side of the extension 2 to fit the wall. The design of the arc-shaped concave surface 22 takes into account the curvature of the wall, so that the casting strip can fit tightly with the wall, thereby improving the stability and aesthetics of the overall structure.

[0027] The width of the model opening 11 and the expansion opening 21 is set to 5mm. This size can effectively control the forming thickness of the casting strip and ensure the uniformity and consistency of the casting strip.

[0028] The surfaces of the model body 1 and the extension 2 are provided with an anti-stick coating. This coating can be silicone oil or other anti-stick materials. Its function is to optimize the demolding effect, reduce the adhesion between the model and the casting strip, and thus improve the construction efficiency.

[0029] For material selection, PVC material is preferred for the main body 1 and extension 2 of the model due to its good weather resistance and ease of processing. The overall length is designed to be 2 meters, and the cross-sectional dimensions are 50mm × 15mm. This size design facilitates operation by construction personnel and can meet the needs of most projects.

[0030] The cross-sectional shape of the model opening 11 and the extended opening 21 can be trapezoidal or rectangular. The specific shape is selected according to the actual decorative effect requirements to adapt to different design styles and construction requirements.

[0031] This novel external wall casting strip deep groove model significantly improves the construction quality and efficiency of external wall deep grooves. The uniform filling of the casting material and the arc-shaped concave surface design allow the model to better adapt to the wall structure, reducing construction difficulty and improving construction accuracy. The application of an anti-stick coating further optimizes the demolding effect, reduces adhesion between the model and the casting strip, and improves construction efficiency.

[0032] This utility model presents a novel deep groove model for external wall casting strips, which not only solves the problems existing in the construction of traditional casting strips, but also improves construction efficiency and quality, and has good application prospects.
