Description

Technical Field

[0001] The utility model relates to the technical field of water supply pipeline laying equipment, in particular to a half-pipe elbow. Background Art

[0002] There are two methods for laying water pipes behind the water meter in a typical residence or apartment: through the ceiling beam or through the floor screed. Ceiling-laid water pipes, located within the ceiling, are relatively easy to inspect and maintain. No grooves or reserved space are required in the floor, which does not affect the integrity and usability of the floor. Furthermore, the pipes are concealed within the ceiling or can be installed through the beam under the slab and painted the same color as the floor, without affecting the interior aesthetics or decor. However, since ceiling-laid water pipes require drilling holes in the beams, construction is more difficult and risky. Construction or design errors may affect the stability of the building structure, and laying through beams and ceilings increases material and labor costs. Furthermore, the limited space in some buildings' ceilings may not be conducive to laying large quantities of pipes. For cost reasons, many buildings lay water pipes through the screed. This method is simpler to install, does not require major structural modifications, and allows for flexible pipe layout, making it suitable for large-scale pipe installations.

[0003] However, laying water pipes on the ground leveling layer will also face some problems. Once the pipes need to be maintained or replaced, the ground may need to be damaged, which increases the difficulty and cost of maintenance. In addition, the presence of pipes may limit the use of the ground. For example, when laying floors or tiles, the location of the pipes needs to be considered. Most importantly, since the thickness of the structural plate is generally 120mm, the leveling layer is 25mm, and the floor decoration surface is 25mm, and the outer diameter of the indoor water supply pipe is generally 25mm (some branches are 20mm), if the pipes do not cross, they can be laid directly on the leveling layer. Once the pipes cross, they need to be laid in grooves. In fact, there are many places where water supply or hot water pipes cross indoors. For the convenience of construction, construction units usually lay them in grooves at the water supply pipes or hot water pipes, and the water supply branch pipes or hot water branch pipes that cross the water supply or hot water pipes are laid in the leveling layer. If Figure 1 and Figure 2 As shown, the water supply pipe 100 and the water supply branch pipe 160 are laid crosswise. During construction, the construction unit generally sets a grooving area 110 on the structural floor 130 where the water supply pipe 100 is laid, for laying the water supply pipe 100. It can be seen that when ordinary water supply pipe fittings are used to deal with the crossing problem, it is necessary to press grooves along the indoor water supply main pipe, and the grooving range is wide.

[0004] Therefore, in order to reduce the area of the groove pressing area 110, some construction units use pipe elbows to deal with the pipe crossing problem, such as Figure 3 and Figure 4 As shown, a groove area 110 is provided on the structural floor 130 at the intersection of the pipes for laying conventional pipe elbows 170. Figure 1The area of the medium pressure tank area 110 is formed by using a conventional pipe elbow 170. Figure 2 The area of the medium pressure groove area 110 is greatly reduced, and the groove is only required at the position of the conventional pipe elbow 170. However, the pressure groove still occurs at the construction site, which will damage the surface layer of the structure and affect the stability of the structure. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present invention aims to provide a half-pipe elbow to solve the problem that when laying water supply pipes on the ground leveling layer, grooves must be pressed on the structural floor when the pipes cross, which causes damage to the structural surface layer and affects the structural stability. The specific technical solution is as follows:

[0006] A half-pipe elbow comprises joint portions with circular cross sections at both ends for connecting to water pipes, a cross portion in the middle for crossing with other half-pipe elbows, and two diameter-reducing portions for connecting the joint portions and the cross portion;

[0007] The top surface of the intersection portion is a plane, and its height does not exceed half of the outer diameter of the joint portion.

[0008] As a preferred embodiment, the diameter-changing portion is a smooth arc-shaped surface.

[0009] As a preferred embodiment, the intersection portion is a cuboid with a horizontal bottom surface.

[0010] As a preferred embodiment, the top of the intersection is a square.

[0011] As a preferred embodiment: the side length of the square does not exceed 40 mm.

[0012] As a preferred embodiment: the water flow cross-sectional area inside the intersection part is not less than the water flow cross-sectional area inside the joint part.

[0013] As a preferred embodiment, the height of the intersection does not exceed 12.5 mm.

[0014] As a preferred embodiment, the height of the diameter-changing portion gradually decreases and the width in the horizontal direction gradually increases in the direction from the joint portion to the intersection portion.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model sets a diameter-reducing part and a crossing part between the two joint parts of the half-pipe elbow, and the top surface of the crossing part is a plane and the height does not exceed half of the outer diameter of the joint part. Therefore, when the two half-pipe elbows cross, the two crossing parts intersect, and one of the crossing parts is inverted so that the planes on the tops of the crossing parts contact each other. The height of the two crossing parts superimposed together will not exceed the outer diameter of the joint part, and the crossing of the water pipes can be completed smoothly, so there is no need for grooving and laying, which is convenient for installation, saves costs, and can ensure the stability of the structure.

DETAILED DESCRIPTION

[0028] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0029] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0030] Example 1

[0031] Combine Figures 5 to 10 As shown, a half-pipe elbow 150 includes joints 200 at both ends, an intersection 202 in the middle, and two sections of reducing parts 201 for connecting the joints 200 and the intersection 202. The type of joint 200 is not limited, and different types of joints 200 are selected according to different water supply pipes 100 and water supply branches 160. In this embodiment, a common water pipe joint with a circular cross section is used, and the joint 200 is roughly cylindrical or truncated. The reducing part 201 can be inclined or curved to ensure smooth water flow. The interior is preferably an arc surface, which is used to connect the joint 200 and the intersection 202. Therefore, one end of the reducing part 201 is circular, and the other end matches the cross section of the intersection 202.

[0032] The top of the intersection 202 is a plane. To ensure maximum space utilization and a water flow rate no less than that of the water supply pipe 100, the intersection 202 is preferably a rectangular parallelepiped. When crossing, one of the half-pipe elbows 150 is inverted so that the top planes of the two half-pipe elbows 150 touch each other. Since the height of the intersection 202 does not exceed half of the joint 200, when the two joints 200 are stacked, their height does not exceed the height of the leveling layer. Therefore, there is no need for grooving, which can save costs and prevent the stability of the structure from being affected by grooving. The commonly used specifications for the joint are generally DN15 and DN20. The outer diameter of DN20 is equivalent to the height of the leveling layer, which is about 25mm. Therefore, the height of the intersection 202 generally does not exceed 12.5mm. The height of the variable diameter portion 201 gradually decreases from the joint 200 to the intersection 202, and the width gradually increases.

[0033] To maximize the contact area between the two half-pipe elbows 150 when stacked, ensuring stability, the top surface of the intersection 202 is preferably square. Furthermore, to ensure that the flow cross-section of the intersection 202 is no less than that of the joint 200, the side length of the top of the intersection 202 is no less than 40 mm. This value is easily obtained using the volume formulas for rectangular parallelepipeds and cylinders, and detailed calculations are not provided here.

[0034] Under the premise of not reducing the water flow, the utility model reduces the height of the intersection 202 and increases the width of the intersection 202 so that the height of the intersection 202 does not exceed half of the leveling layer, so that the water supply pipe 100 and the water supply branch pipe 160 can cross and overlap at the intersection 220, and can pass through the pipe smoothly without grooving, thereby reducing construction costs and ensuring the stability of the structure, and is suitable for promotion and use.
