Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a finished inside corner component and inside corner structure that facilitates waterproof construction. Background Technology

[0002] An inside corner (or recessed corner) is a recessed corner on a wall surface, commonly found at the four corners of a room, or at the angle formed between a wall and the ceiling, or between two walls. It corresponds to a protruding outside corner (or protruding corner). In building construction, if an inside corner is a right angle, the waterproofing material often cracks due to stress concentration at the right angle. Therefore, the conventional practice is to round off the inside corner after the reinforced concrete frame forms the wall, thus facilitating waterproofing. However, this subsequent repair method is not only time-consuming and labor-intensive but also reduces overall construction efficiency.

[0003] A search revealed that patent document CN207419957U discloses an arc-shaped inside corner strip, which includes a first inside corner side, a second inside corner side, and an arc-shaped assembly edge. The first inside corner side and the second inside corner side are respectively fixed at both ends of the assembly edge, and the included angle α between the first inside corner side and the second inside corner side is 90°-179°.

[0004] However, the application of this curved corner strip in the construction process is as follows: after the concrete wall has been poured and formed, it is assembled at the inside corner of the wall and fixed with a snap-fit ​​plate, making it part of the wall surface. Its main function is to utilize the straightness of the component itself to make the wall joints straighter and to simulate the decorative effect of stone joints.

[0005] In summary, the existing technology does not include a technical solution for pre-setting internal corner molds during the reinforced concrete frame stage, i.e., before concrete pouring. This cannot fundamentally avoid secondary processing in the later stages, which is precisely the problem that urgently needs to be solved in the current construction process. Utility Model Content

[0006] The purpose of this utility model is to solve the problems in the prior art by proposing a pre-made inside corner component that is easy to waterproof. By pre-setting this inside corner component at the corresponding position in the steel frame, a regular and smooth arc-shaped inside corner can be formed on the wall after the concrete is poured.

[0007] To solve the above problems, this utility model provides the following technical solution:

[0008] A prefabricated corner component that facilitates waterproofing construction includes an arc-shaped portion, both ends of which are bent inward to form a stop portion, and both stop portions are provided with a corner portion. The stop portion and the outer side of the corner portion together form an open receiving area.

[0009] As a further embodiment of this utility model, the thickness of the arc-shaped part, the stop part, and the inside corner part is all set to 3mm.

[0010] As a further embodiment of this utility model, the stop portion and the inside corner portion are arranged at right angles.

[0011] As a further embodiment of this utility model, the planes where the two internal corners are located are arranged at right angles.

[0012] As a further embodiment of this utility model, the arc-shaped part and the inside corner part are an integral structure.

[0013] As a further embodiment of this utility model, the arc-shaped part is a quarter-circle arc structure.

[0014] As a further embodiment of this utility model, both stop portions are arranged radially along the arc-shaped portion.

[0015] As a further aspect of this utility model, the radius of the arc-shaped portion is 50mm.

[0016] This application also provides an inside corner structure, including the above-mentioned finished inside corner component that facilitates waterproof construction, and a template for adapting to the open receiving area, wherein one end and one side of the template abut against the stop and the inside corner, respectively.

[0017] As a further aspect of this utility model, the thickness of the template is the same as the width of the stop portion.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By pre-setting this component, a regular and smooth arc-shaped inside corner can be formed in one go during concrete pouring, eliminating the need for additional manual steps to increase the arc angle, improving construction efficiency and reducing labor costs. Furthermore, the one-piece arc-shaped structure optimizes the foundation for waterproofing layer installation, avoiding the leakage risk caused by stress concentration or insufficient coating at traditional right-angle inside corners, thus providing a high-quality foundation for subsequent waterproofing construction.

[0020] 2. By creating an open receiving area together with the stop section and the inside corner section, this open receiving area provides a precise positioning and support benchmark for formwork installation on the construction site. It stably accommodates and clamps the formwork, ensuring that it will not shift or deform during concrete pouring, thus guaranteeing the final inside corner's precise dimensions and straight lines. Simultaneously, this tight fit effectively prevents concrete slurry leakage, reducing subsequent cleaning work and further improving construction quality and cleanliness.

[0021] 3. By limiting the stop and the inside corner to be arranged at right angles, the inside corner component can be matched with the most common right-angle wall corners in buildings. This standardized right-angle design makes the component highly versatile and can be widely used in the inside corners of walls in various types of buildings.

[0022] 4. Based on the right-angle layout of the stop and the inside corner, the planes where the two inside corners are located are also required to be right-angled. The two mutually perpendicular inside corner planes can fit tightly against the templates or walls from two directions, working together to ensure that the final inside corner of the wall is a standard 90-degree right angle, effectively avoiding quality defects such as tilted corners or inaccurate angles.

[0023] 5. By defining the curved section and the inner corner as a single integrated structure, weak points at the component connections are eliminated, giving the entire component extremely high structural strength and integrity. This allows it to better withstand the impact and lateral pressure during concrete pouring without easily being damaged. Secondly, the integrated structure ensures an absolutely smooth and continuous transition surface on the inner side of the component, without any seams or gaps. This makes demolding smoother and allows for the formation of seamless, smooth curved inner corner surfaces.

[0024] 6. By limiting the arrangement of both stops along the radial direction of the arc-shaped part, the two stops act as radial support ribs, providing symmetrical and uniform support for the arc-shaped part. This ensures that the pressure of the concrete fluid is evenly transmitted and dispersed, preventing deformation or displacement of the internal corner component due to uneven stress during the pouring process.

[0025] 7. By combining the internal corner components with the formwork, a complete internal corner structure is formed, realizing a collaborative working mode of "component positioning formwork". Specifically, the stop and internal corner parts on the internal corner components provide precise installation support and limits for the formwork, making the formwork installation fast, accurate and firm, simplifying the complex internal corner formwork process and improving formwork efficiency.

[0026] 8. By limiting the thickness of the template to be the same as the width of the stop, once the template is installed, its outer surface can be perfectly flush with the outer edge of the stop. This allows the wall to form a continuous, stepless, smooth surface during subsequent plastering or decorative layer construction, avoiding the need for additional leveling processes caused by protruding or recessed components, and improving the final construction quality and aesthetic effect of the wall.

[0036] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] like Figures 1-2 As shown, a prefabricated corner component that facilitates waterproofing construction includes an arc-shaped portion 1, both ends of which are bent inwards to form a stop portion 2. Simultaneously, both sets of stop portions 2 are provided with corner portions 3. The outer sides of the stop portions 2 and the corner portions 3 together form an open receiving area 4. Therefore, under the above layout design, the overall shape of the corner component is... Figure 2 As shown, the two sets of open accommodating areas 4 are arranged horizontally and vertically, respectively. It should be noted that the inner and outer sides in this section are based on the arc-shaped part 1. The side of the arc-shaped part 1 closer to its center is called the inner side, and the side of the arc-shaped part 1 farther from its center is called the outer side. Correspondingly, the side of the inside corner part 3 closer to the center of the arc-shaped part 1 is called the inner side, and the side of the inside corner part 3 farther from the center of the arc-shaped part 1 is called the outer side.

[0038] In subsequent use, before the concrete is poured for the reinforced steel frame a, templates 5 are respectively installed on the two sets of open receiving areas 4 of the internal corner component of this application. The shape of the templates 5 is adapted to the shape of the open receiving area 4. Preferably, the stop part 2 and the internal corner part 3 are arranged at right angles, that is, after the rectangular template 5 is placed in the open receiving area 4, one end and one side of the template 5 abut against the stop part 2 and the internal corner part 3 respectively, and the thickness of the template 5 is designed to be the same as the width of the stop part 2. The resulting internal corner structure can be formed by... Figure 3 and Figure 4 To represent it.

[0039] Next, the inside corner structure is assembled at the inside corner of the steel frame a, so that the arc-shaped part 1 abuts against the inside corner and the two sets of templates 5 abut against one side of the steel frame a respectively. Then, fasteners are used to secure and lock the templates 5 to the side of the steel frame a and the inside corner part 3 to the steel frame a. This state can be achieved by... Figure 5 (Fasteners are not shown in the diagram) During the subsequent concrete pouring of the reinforcing frame a, the concrete can fill the area between the curved part 1 and the inside corner of the reinforcing frame a. Simultaneously, during the pouring process, the formwork 5 will block the concrete inside the reinforcing frame a to prevent overflow. After a period of time, the concrete and the reinforcing frame a together form wall b. Then, by releasing the fasteners, the inside corner structure composed of the formwork 5 and the inside corner component can be disassembled, ultimately obtaining the structure of wall b. Figures 6-7 To illustrate, the inside corner of wall b is an arc shape that matches the arc shape of arc part 1.

[0040] It should be noted that under different shapes of steel frame a, the included angle between the two internal corners 3 of the internal corner member will also change. This application does not limit itself to this. Figure 1 and Figure 2 The two internal corner sections 3 are shown to be arranged at right angles in the plane, therefore, this corresponds to... Figure 5 The example shown is a right angle.

[0041] Furthermore, to improve the overall rigidity and stability of the internal corner component, this application sets the arc-shaped part 1 and the internal corner part 3 as an integral structure. Preferably, the integral structure uses 3mm thick Q235 cold-rolled steel plate and is treated with anti-rust treatment (it can be painted with anti-rust paint or galvanized steel plate). One embodiment is proposed below: the arc-shaped part 1 is set as a quarter-circle arc structure, and the radius of the arc-shaped part 1 is simultaneously set to 50mm. Then, both stop parts 2 are arranged radially along the arc-shaped part 1. The shape of the internal corner component shown in this embodiment can be derived from... Figure 1 and Figure 2 To represent it.

[0042] Compared to the existing technology where the corner of the wall b is rounded after the concrete is poured into the steel frame a to form the wall b, this application pre-sets the corner component at the corner of the steel frame a and provides a stop 2 on it that cooperates with the template 5. This allows the corner component to be fitted with the steel frame a before pouring. After the pouring is completed, the corner component can be directly removed to obtain an arc-shaped corner integrally formed with the wall b, and the obtained arc-shaped corner has a regular shape.

[0043] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
