Description

Technical Field

[0001] This utility model relates to the field of hot and cold water sleeve installation technology, and relates to a hot and cold water sleeve installation component. Background Technology

[0002] Residential buildings involve the pre-installation and embedding of numerous hot and cold water sleeves. However, traditional pre-installation and embedding methods for these sleeves present several problems: 1. During construction, the hot and cold water sleeves 2 need to be welded and fixed using the stirrups 3 within the beam, which can easily damage the main reinforcing steel 4 within the beam; 2. Because the length of the hot and cold water sleeve 2 is less than the width of the beam, the beam needs to be chipped away after concrete pouring to locate the sleeve, damaging the beam and increasing labor costs. Furthermore, the ends of the sleeve are difficult to close during plastering, resulting in irregularities and affecting the appearance and delivery; 3. The sleeves need to be fixed using a "well"-shaped welding method with round steel, which is inefficient. Concrete vibration can easily cause the stirrups 3, main reinforcing steel 4, and sleeves to shift or become misaligned, requiring rework and re-drilling later, damaging the beam and increasing material and labor costs (in conjunction with...). Figure 1 ). Utility Model Content

[0003] To address the aforementioned technical problems in the existing technology, a hot and cold water sleeve installation component is provided.

[0004] The purpose and effects of this utility model are achieved by the following specific technical means:

[0005] A hot and cold water sleeve installation component includes a sleeve and two retainers respectively fitted onto both ends of the sleeve. Each retainer has a first sealing ring installed on its outer end and a second sealing ring installed on its inner end. The second sealing ring is in contact with the sleeve, and at least one mounting plate is fixed on the outer wall of each retainer.

[0006] Optionally, at least one of the retainers has a groove on its inner wall, and a slider is slidably connected in the groove, the slider being fixedly connected to the sleeve.

[0007] Optionally, the length of the sleeve is 0.5-3cm less than the width of the building beam, and the length of the fastener is 2.5-5cm.

[0008] Optionally, both the sleeve and the retainer are metal tubes.

[0009] Optionally, the mounting plate is welded to the retainer and protrudes from the retainer, and the first sealing ring contacts the inner side of the mounting plate.

[0010] Optionally, each mounting plate has a self-tapping screw hole, and a self-tapping screw is threaded into each of the self-tapping screw holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This type of hot and cold water sleeve installation component eliminates the need for welding stirrups to the sleeve, thus preventing damage to the main steel reinforcement. By setting two fixing devices that are respectively sleeved and / or slidably sleeved at both ends of the sleeve, the gap between the sleeve and the building beam can be filled. After the concrete is poured, there is no need to chip away at the beam to find the sleeve inside, thus preventing damage to the beam. Furthermore, the ends of the sleeve are easier and more regular to close during plastering, without affecting the appearance or delivery. Finally, this hot and cold water sleeve installation component is directly fixed to the formwork, making it more stable and less prone to displacement during concrete vibration.

[0021] Please see Figure 2-7 The embodiments of this utility model will be further described below;

[0022] like Figure 2-7A hot and cold water sleeve installation component includes a sleeve 2, the length of which is 0.5-3cm less than the width of the building beam. The sleeve 2 is typically made of a metal pipe with an outer diameter of 40mm, such as stainless steel or aluminum alloy. It also includes two fasteners 5 respectively fitted onto both ends of the sleeve 2. The length of the fasteners 5 is 2.5-5cm. The fasteners 5 are DN40 fasteners that match the sleeve 2. It should be noted that the diameters of the sleeve 2 and the fasteners 5 are not limited and can be selected according to actual conditions. The sleeve 2 is a metal pipe, such as stainless steel or aluminum alloy. A first sealing ring 8 is installed on the outer end of each fastener 5, and a second sealing ring 9 is installed on the inner end of each fastener 5. The second sealing ring 9 is in contact with the sleeve 2. At least one mounting plate 10 is fixed on the outer wall of the fastener 5. Each mounting plate 10 has a self-tapping screw hole, and a self-tapping screw 11 is threaded into each self-tapping screw hole.

[0023] like Figure 4-6 As shown, at least one of the fixtures 5 has a groove 6 on its inner wall, and a slider 7 is slidably connected in the groove 6. The slider 7 is fixedly connected to the sleeve 2.

[0024] like Figure 4 and 7 As shown, the mounting plate 10 is welded to the retainer 5 and protrudes from the retainer 5, and the first sealing ring 8 is in contact with the inner side of the mounting plate 10.

[0025] In this embodiment, the hot and cold water sleeve installation component is installed in the building beam. The building beam includes multiple templates 1 and multiple main steel bars 4 forming a square. The multiple main steel bars 4 are tied together by multiple stirrups 3. The multiple templates 1 are respectively fixed around the outside of the square main steel bars 4, and the multiple templates 1 are fixed together with the building.

[0026] Before pouring the building beam, two fasteners 5 are respectively fitted onto both ends of the sleeve 2, with the first sealing ring 8 on the fastener 5 facing outwards. The slider 7 is made of iron. After installation, the iron slider is welded to the outer wall of the sleeve 2, thus assembling a hot and cold water sleeve installation component. This hot and cold water sleeve installation component can be mass-produced in a factory. In the design, the length of the sleeve 2 is 1.5cm less than the width of the building beam, and the length of the fastener 5 is 4cm. Two mounting pieces 10 are welded onto each fastener 5, and these two mounting pieces 10 are distributed on the same side. This design not only ensures the later fixation... The stability of the fixing device 5 installed on the template 1 is improved, and the construction worker only needs to fix the mounting piece 10 on one side, which is convenient for operation. In order to reduce the processing difficulty, each hot and cold water sleeve installation component can select only one fixing device 5 to open the sliding groove 6, that is, one fixing device 5 is slidably connected to the sleeve 2, and the other fixing device 5 is sleeved to the sleeve 2. During the later installation, it is only necessary to support the sleeved fixing device 5 and the sleeve 2. If it is for the convenience of the later installation, the sliding groove 6 can also be opened on each fixing device 5, so that there is no need to worry about the fixing device 5 falling off the sleeve 2 when the sleeve 2 is removed, which would slow down the installation process.

[0027] During installation, move the two retainers 5 towards the center of the sleeve 2 to minimize the overall length of the hot and cold water sleeve installation component. This facilitates placing the assembled hot and cold water sleeve installation component within the square-shaped main steel reinforcement 4. The length of the hot and cold water sleeve installation component corresponds to the width of the building beam. After the hot and cold water sleeve installation component is moved to the designated position, move the two retainers 5 outwards until the first sealing ring 8 at the outer end of the retainer 5 contacts the template 1. Use a tool to fix the self-tapping screws 11 on the mounting plate 10 to the template 1, thus completing the fixing of the hot and cold water sleeve installation component. First, this application eliminates the need to weld the stirrups 3 to the sleeve 2, thus avoiding damage to the main reinforcing steel 4. Second, by setting two fasteners 5 to be sleeved and / or slidably sleeved at both ends of the sleeve 2, the gap between the sleeve 2 and the building beam can be filled. After the concrete is poured, there is no need to chip away at the beam to find the sleeve 2 inside the beam, thus avoiding damage to the beam. Furthermore, the ends of the sleeve 2 are easier and more regular to close during plastering, without affecting the appearance or delivery. Finally, the hot and cold water sleeve installation component is directly fixed to the formwork 1, making it more stable and less prone to displacement during concrete vibration.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
