Description

Technical Field

[0001] The utility model relates to the technical field of building pipes. Specifically speaking, it relates to a combined component of a beam-piercing sleeve and a fresh air pipe. Background Technique

[0002] With the development of the real estate industry, the original just-needed housing market has gradually developed into an improved housing demand market. The state and local governments are also vigorously promoting high-quality improved housing. Among them, the household fresh air system is a standard configuration system. In order to ensure the indoor net height after installation, the household fresh air pipes are all installed through the beam.

[0003] The conventional construction process is as follows: When pouring the structural beam, the steel sleeve is pre-embedded by the civil engineering. The sleeve is two sizes larger than the fresh air pipe. For example, for a De110 air duct, a DN150 steel sleeve needs to be reserved. Refer to Figure 1 As shown. The diameter of the sleeve is relatively large, and the structural beam needs to be heightened to meet the requirement of leaving a hole in the beam, which increases the cost and reduces the net height at the bottom of the beam. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a combined component of a beam-piercing sleeve and a fresh air pipe, which improves the material of the beam-piercing sleeve and conducts structural design, so that it can be used as a pipe fitting of the fresh air pipe and can be used without enlargement. It saves the construction process, saves pipe materials and concrete materials, and effectively improves the net height of the residence.

[0005] The utility model provides a combined component of a beam-piercing sleeve and a fresh air pipe, and the combined component of the beam-piercing sleeve and the fresh air pipe includes: a steel-plastic composite pipe and a fresh air pipe.

[0006] The steel-plastic composite pipe includes a steel pipe base layer and a plastic layer from the inside to the outside. The two ends of the steel-plastic composite pipe are respectively provided with bent portions extending outwards; when in use, one end of the fresh air pipe is connected to the bent portion.

[0007] Furthermore, by setting a steel-plastic composite pipe with a steel pipe base layer on the inner layer and a plastic layer on the outer layer, the strength of the steel-plastic composite pipe pre-embedded during the pouring of the structural beam can be ensured, and at the same time, the outer plastic layer can meet the sanitary requirements of the fresh air system. In addition, the utility model opens bent portions extending outwards at both ends of the steel-plastic composite pipe, which is convenient for the plastic fresh air pipe to be directly connected and fixed to the bent portion, and is convenient for direct use by the later HVAC. The utility model improves the material and structure of the beam-piercing sleeve and enables it to be used as a pipe fitting of the fresh air pipe without enlargement. It saves the construction process, saves pipe materials and concrete materials, and effectively improves the net height of the residence.

Furthermore, when in use, one end of the fresh air pipe is connected to the receiving groove, and it can be fixedly connected by applying an adhesive to one end of the fresh air pipe.

[0009] Optionally, one end of the fresh air duct is provided with a socket groove. Further, during use, the socket groove is connected to the bent portion.

[0010] Optionally, the socket groove is composed of a second vertical portion and a first inclined portion. Further, during use, the socket groove is inserted into the first vertical folding portion. For example, the inner side of the first inclined portion contacts the outer side of the first vertical folding portion, the inner side of the first vertical folding portion contacts one side of the second vertical portion, and the bottom surface of the second vertical portion contacts the surface of the first horizontal folding portion. The connection and fixation can be achieved by applying an adhesive in the socket groove. This further ensures the strength and sealing performance of the connection between the fresh air duct and the steel-plastic composite pipe passing through the beam.

The inclined section extends obliquely outward from one end of the fresh air duct, one end of the vertical section is connected to the inclined section, and the other end of the vertical section extends in the direction away from the inclined section along the direction of the fresh air duct. The second vertical portion is formed by extending one end of the fresh air duct in the direction of the fresh air duct towards the position close to the bent portion. During use, the inner side of the vertical section contacts the outer side of the first vertical folding portion, and the inner side of the first vertical folding portion contacts one side of the vertical section.

[0013] Optionally, the inner diameter of the steel-plastic composite pipe except for the bent portion is equal to the inner diameter of the fresh air duct.
