Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction technology for treating the inside and outside corners of waterproof base layers of concrete components, and in particular to an auxiliary device for construction of inside and outside corners of waterproof base layers of concrete components. Background Technology
[0002] When waterproofing components such as basement side walls, pool side walls, and roof parapet walls are applied, the internal and external corners of the base layer should be rounded or chamfered at 45°.
[0003] In the existing technology, the common practice for rounded inside corners is to use mortar to form them after the concrete of the component is poured, while the 45° chamfer of outside corners is usually achieved by grinding the right angle of the outside corner into a 45° chamfer.
[0004] The applicant has discovered that the prior art has at least the following technical problems:
[0005] The existing method of rounding inside corners adds the steps of mortar preparation and manual troweling. The bonding between mortar and concrete is often prone to quality problems, which can easily cause the rounded corners to fall off. In addition, the material and labor costs are high and the quality is difficult to guarantee. The existing method of chamfering outside corners at 45° requires a lot of manpower and the construction dust is harmful to human health. It is neither economical nor environmentally friendly.
[0006] Therefore, there is an urgent need for an auxiliary device for the construction of waterproof base layers at the inside and outside corners of concrete components to solve the above-mentioned technical problems. Utility Model Content
[0007] The purpose of this utility model is to provide an auxiliary device for the construction of internal and external corners of waterproof base layers for concrete components. Applied to the reinforcement of formwork at the internal and external corners of basement side walls, pool side walls, or other components, it allows for the one-time formation of rounded internal corners or 45° chamfered external corners during concrete pouring. This effectively solves the problems of increased costs, quality defects, and environmental pollution caused by secondary construction of rounded internal and external corners or 45° chamfers. The numerous technical effects of the preferred technical solutions provided by this utility model are detailed below.
[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0032] Figure 1 This is a structural schematic diagram of this embodiment. Figure 2 yes Figure 1 A front view structural diagram, Figure 3 yes Figure 1 A schematic diagram of the left-side view structure, as shown below. Figures 1-3 As shown, this utility model provides an auxiliary device for the construction of internal and external corners of waterproof base layers for concrete components, including a first body 1 and a second body 2.
[0033] The first body 1 includes a first side 11 and a second side 12 opposite to the first side 11; the second body 2 is connected to the end of the first body 1, and the second body 2 includes a third side 21 and a fourth side 22 opposite to the third side 21. The third side 21 is set as an arc surface and one end is coplanar with the first side 11. The fourth side 22 is set as a chamfered surface and one end is coplanar with the second side 12.
[0034] This auxiliary device for the construction of waterproof base layers at the inside and outside corners of concrete components features an arc shape on the outer side of the bottom and a chamfer shape on the inner side. It can be used for formwork reinforcement at the inside and outside corners of concrete components, making it highly versatile.
[0035] As an optional implementation method, Figure 4 yes Figure 1 A top-view structural diagram, such as Figure 4 As shown, the first body 1 includes a straight section, and the width of the first body 1 is the same as the width of the second body 2. The overall structure is simple and easy to manufacture. In use, the height of the straight section of the first body 1 in this embodiment can be adjusted according to the height of the concrete component to meet different usage requirements.
[0036] As an optional implementation, the curved surface in this embodiment includes a circular arc with a radius of 50 mm. The chamfered surface includes a 45° chamfer. In this embodiment, the chamfered surface specification is C = 30 mm × 45°.
[0037] This auxiliary device for the construction of waterproof base layer of concrete components can be used as a template for the internal and external corners of components such as basement side walls, water tank side walls, and roof parapet walls. After the concrete is poured, the internal corner rounded or the external corner 45° bevel can be formed in one go.
[0038] As an optional implementation, the first body 1 and the second body 2 are integrally formed, avoiding the need for a connection structure between the first body 1 and the second body 2. This saves connection materials and makes the connection more stable and reliable in use.
[0039] In this embodiment, both the first body 1 and the second body 2 are made of plastic steel. Plastic steel has the advantages of being lightweight, rigid, tough, and reusable. It can fully withstand the lateral loads of concrete and the dynamic loads of concrete construction without deformation or damage. It is the preferred material for auxiliary devices used in the construction of waterproof base layers at the inside and outside corners of concrete components.
[0040] The auxiliary device for constructing internal and external corners of waterproof base layers for concrete components in this embodiment has two customizable bodies, 1 and 2. It is highly adaptable and can be used with any type of conventional template. The length and height of the device can be customized according to the characteristics of the concrete component, and it is reusable. Using this auxiliary device for constructing internal and external corners of waterproof base layers for concrete components, a rounded internal corner or a 45° chamfered external corner can be formed on the component structure in one step. It is suitable for waterproofing construction of components such as basement side walls, pool side walls, and roof parapet walls.
[0041] As an optional implementation, the first body 1 includes two sets, with the two sets of first bodies 1 respectively disposed on both sides of the second body 2.
[0042] This design allows the auxiliary device for constructing the internal and external corners of the waterproof base layer of this concrete component to be freely matched with conventional templates of various materials. It can be used to create rounded corners or 45° chamfers on one side of the side wall, or to create rounded corners or 45° chamfers on both sides of the side wall.
[0043] As an optional implementation, a plurality of connecting structures 10 are evenly distributed on the first body 1 to facilitate connection. In this embodiment, the connecting structures 10 include a plurality of structures, which are evenly distributed on the first body 1.
[0044] like Figures 5-8 As shown, the working principle of this embodiment includes:
[0045] If the third side 21, i.e. the arc surface, is applied to the inside corner of the component, the device can be used as a template for the inside corner of components such as basement side walls, water tank side walls, and roof parapet walls. After the concrete is poured, the inside corner arc can be formed in one go.
[0046] If the fourth side 22, i.e. the chamfered surface, is applied to the external corner of the component, and this device is used as a template for the external corner of components such as basement side walls, water tank side walls, and roof parapet walls, the external corner can be formed at 45° chamfer in one go after the concrete is poured.
[0047] Therefore, by using this auxiliary device for the construction of waterproof base layers at the inside and outside corners of concrete components, the problems of increased costs, quality defects, and environmental pollution caused by secondary construction of rounded inside corners and 45° chamfered outside corners can be effectively solved.
[0048] The beneficial effects of this embodiment are:
[0049] This auxiliary device for constructing the internal and external corners of waterproof base layers for concrete components consists of a first body 1 and a second body 2. The first body 1 includes a first side 11 and a second side 12 opposite to the first side 11. The second body 2 is connected to the end of the first body 1 and includes a third side 21 and a fourth side 22 opposite to the third side 21. The third side 21 is an arc surface with one end coplanar with the first side 11, and the fourth side 22 is a chamfered surface with one end coplanar with the second side 12. That is, the bottom of the device has an arc shape on the outer side and a chamfer shape on the inner side. The overall structure is simple and easy to operate. By applying this device to the formwork reinforcement of the internal and external corners of basement side walls, pool side walls, or other components, the components can form an arc corner or a 45° chamfered corner in one go during concrete pouring. This effectively solves the problems of increased costs, quality defects, and environmental pollution caused by secondary construction of arc corners and 45° chamfers for internal and external corners.
[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
