[0002] During renovation projects, it is common to encounter situations where the original building's floor height is too low, and the limited space within the ceiling makes it difficult to install pipelines. This is especially true for older buildings constructed before 2000, which often have excessively high beams and low floor heights. This leads to a conflict between the space available for installing mechanical and electrical pipelines and the space within the ceiling.

[0003] In response to the problem of excessive beam height and low floor height in existing buildings, which leads to spatial conflicts between the installation of electromechanical pipelines and the suspended ceiling, those skilled in the art have been searching for solutions.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0026] Please refer to Figure 1 and Figure 2The pipeline through-beam structure based on the opening in beam 1 includes: a beam 1 with openings 10 and several U-shaped clamps 2 fixed to the outside of beam 1 around the openings 10; wherein the two flanges of the U-shaped clamps 2 are located on the upper and lower surfaces of beam 1, respectively. By opening the openings 10 in beam 1 and passing the pipelines through the openings 10, the ceiling effect is ensured, effectively solving the problem of space conflict between the installation of electromechanical pipelines and the ceiling in old buildings due to excessive beam height and low floor height. The U-shaped clamps 2 on the outside of beam 1 around the openings 10 (specifically on the first opposite side of the first opening 10) effectively enhance the strength of beam 1 at the first opposite side of the opening 10, initially and effectively improving the structural safety of beam 1 after the opening, and ensuring construction safety.

[0027] In this embodiment, opening holes 10 in the beam weakens the beam's shear and bending resistance, requiring structural reinforcement measures. This application adopts two U-shaped hoop plates 2 on the beam body 1 on the first opposite side of each hole 10; the axis of the first opposite side of the hole 10 is perpendicular to the axis of the second opposite side, and the axis of the first opposite side is perpendicular to the axis of the beam body 1.

[0028] Better, such as Figure 2 As shown, two adjacent U-shaped hoops 2 are arranged parallel to each other to increase the strength of the beam 1 on the first opposite side of the hole 10 in multiple ways. The beam 1 adjacent to the hole 10 of the beam 1 is provided with a U-shaped hoop 2, and its two flanges are located on the upper and lower surfaces of the beam 1 respectively. The U-shaped hoop 2 is fixed to the beam 1 by welding or bolts to form an integral load-bearing structure.

[0029] To ensure the load-bearing capacity of beam 1, the number of holes 10 for installing pipelines on it shall not exceed two.

[0030] Preferably, the pipeline through-beam structure further includes: two sets of pressure strips, symmetrically fixed to two sides of the beam 1 and distributed around the hole 10, to reinforce the beam 1 around the hole 10 not covered by the U-shaped clamp 2. Each set of pressure strips includes two strips, symmetrically fixed to the beam 1 on the second opposite side of the hole 10. By strengthening the beam 1 at the first and second opposite sides of the hole 10 through the U-shaped clamp 2 and pressure strips (i.e., reinforcement measures for the open-hole beam 1), the stress concentration area around the hole 10 is fully covered, increasing the overall structural stability of the beam 1 around the hole 10 and avoiding any impact on the load-bearing capacity of the beam 1.

[0031] Preferred, such as Figure 2 As shown, the pressure strip 3 is vertically fixed to the beam 1 by M8 bolts 5. Of course, the pressure strip 3 can also be fixed to the beam 1 in other ways, as long as both are fixed.

[0032] Furthermore, the pipeline through-beam structure also includes several steel pads 4, which are placed in the gap between the pressure strip 3 and the beam 1. The pressure strip 3 is vertically fixed to the beam 1 by the steel pads 4. Here, the steel pads 4 are used to compensate for the height difference between the pressure strip and the beam 1 caused by the presence of the U-shaped hoop 2. Based on the filling of the gap by the steel pads 4, the pressure strip 3 can be more stably fixed to the beam 1.

[0033] In another embodiment, the fixing point of the pressure strip 3 and the beam 1 can be selected at the position where the pressure strip 3 and the U-shaped hoop 2 overlap, that is, the M8 bolt 5 passes through the pressure strip and the U-shaped hoop 2 in sequence and is finally fixed to the beam 1.

[0034] In this embodiment, the open end of each U-shaped hoop 2 faces the inside of the beam 1. Specifically, each U-shaped hoop 2 is first bonded to the outside of the beam 1 with structural adhesive and then fixed with M8 anchor bolts. The two flanges of the U-shaped hoop 2 are located on the upper and lower surfaces of the beam 1, respectively.

[0035] Specifically, in this embodiment, a -100x4 U-shaped hoop plate 2 is used, and two U-shaped hoop plates 2 are set on each side of the hole 10 on the first opposite side; a -100x4 pressure strip 3 is made on the U-shaped hoop plate 2, and one is placed on the top and bottom of each side of the hole 10 on the second opposite side; the U-shaped hoop plate 2 is bonded to the beam body 1 with structural adhesive and fixed with M8 anchor bolts, and the pressure strip is fixed to the U-shaped hoop plate 2 with M8 anchor bolts.

[0036] To better understand the pipeline through-beam structure of this utility model, its construction method will be described in detail below. The specific construction method process is as follows:

[0037] The construction process includes: removal of the original building's beams and decorative surfaces; scanning with a rebar scanner; positioning and marking (marking the appropriate locations for openings 10 and steel plate reinforcement on beam 1); opening of openings 10 in the original beams; reinforcement of the original beams (installing strips and U-shaped stirrups 2 around the openings 10 on beam 1); pipework through the beams; and ceiling sealing. Each construction step is described in detail below:

[0038] 1. On-site manual removal and grinding of the original building's original beams and decorative surfaces: The original decorative layer is removed down to the structural layer, and then manually ground. The original structural beams are ground smooth, and the beam corners are ground into rounded corners with r > 7mm.

[0039] 2. Rebar Scanning, Positioning and Laying Out, Beam Opening: The rebar is scanned manually using a rebar scanner to determine the original beam structure. Without damaging the original beam structure, the rebar gaps are marked out according to the requirements. The distance between two openings should be ≥500mm. The opening locations are determined according to the requirements, and the original beam structure is manually opened (D≤150mm). After the opening is completed, the original beam is reinforced.

[0040] 3. The structural reinforcement uses -100x4 U-shaped hoops, two on each side of the opening; -100x4 pressure strips are installed on the U-shaped hoops, one on the top and one on the bottom of the opening; the U-shaped hoops are bonded to the beam with structural adhesive and fixed with M8 anchor bolts, and the pressure strips are fixed to the U-shaped hoops with M8 anchor bolts.

[0041] 4. After the pipeline reinforcement through the beam is completed, the pipeline installation through the beam will proceed, and the next construction step will be carried out according to the construction procedure.

[0042] Effect Analysis: By adopting the construction scheme of opening holes in the original beam and reinforcing the structure using this utility model, the safety of the beam, the installation height of pipelines, and the effect of the space inside the ceiling are effectively guaranteed, thus meeting the construction conditions for structural reinforcement and pipeline installation in the renovation project.

[0043] In summary, the pipeline through-beam structure based on beam openings provided by this utility model includes a beam with openings and several U-shaped clamps fitted and fixed to the outside of the beam around the openings. By opening openings in the beam and passing pipelines through them, the ceiling effect is ensured, effectively solving the problem of space conflict between the installation of electromechanical pipelines and the ceiling in old buildings due to excessive beam height and low floor height. Simultaneously, the U-shaped clamps on the outside of the beam around the openings effectively improve the structural safety of the beam after the openings are made, ensuring construction safety.
