Description

Technical Field

[0001] The present invention relates to the technical field of building construction, in particular to a method for installing pipelines in a bidirectional dense-rib cavity floor. Background Art

[0002] The dense rib cavity floor is a new type of structural system that combines the advantages of reinforced concrete floor and dense rib cavity slab. It is mainly composed of bottom plate 1, top plate 2 and side wall plate. The side wall plate is a side wall glass magnesium plate 3. Figure 1 shown.

[0003] Utility piping installation typically occurs after the cavity floor baseplate is laid, ensuring the complete installation of the piping system before the top slab is closed. Currently, plumbing installation typically involves on-site drilling. After the dense-ribbed cavity floor baseplate is installed, holes are drilled in the baseplate according to the designed locations. Terminal boxes for the utility lines are embedded within the holes and sealed with cement mortar. Because the boxes rely solely on the baseplate for support, quality defects such as box displacement or indentation can easily occur during wiring and equipment tightening during the plumbing and electrical installation phase. Furthermore, the sidewall glass magnesium panels are connected to the edges of the baseplate and cover plate via prefabricated slots. When the piping system is connected to the terminal boxes, it must penetrate the sidewalls, creating a structural gap at the bottom of the panels. The cement mortar seal at this location is difficult to achieve due to the discontinuous interface, posing a risk of leakage. If the sidewall glass magnesium panels are not properly positioned, the cross-sectional dimensions of the secondary rib beams surrounding the cavity panel cannot be guaranteed after concrete pouring. Summary of the Invention

DETAILED DESCRIPTION

[0063] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0064] Example 1

[0065] like Figure 2As shown, this embodiment provides a bidirectional multi-rib cavity floor pipeline installation method, including the following steps:

[0066] S1: Install cavity plate bottom plate 1;

[0067] Step S1 specifically includes:

[0068] S101: erecting a pin-key scaffolding as a formwork support frame, and laying a formwork on the formwork support frame, with position reference lines drawn on the formwork, which divide the installation areas of each base plate 1;

[0069] S102: hoisting the base plate 1 onto the template;

[0070] S103: Review the template elevation and flatness;

[0071] S104: Before the base plate is officially laid, double-sided tape is pasted on the installation area of ​​the base plate 1;

[0072] S105: Arrange the base plates 1 according to the position reference lines on the template in accordance with the design layout drawing, and place each base plate 1 within the installation area divided by the position reference lines, while ensuring that the outer edge of the bottom of the base plate 1 coincides with the edge of the corresponding position reference line.

[0073] In step S104, double-sided tape is pasted on the four sides of the bottom surface of the base plate 1 at positions corresponding to the template to form a plurality of rectangular frames. The width of the double-sided tape is 2 cm.

[0074] The formwork support frame includes multiple vertical poles. In step S102, when multiple base plates 1 are hoisted at one time, the multiple base plates 1 are first overlapped and placed on the formwork. At this time, the four corner points of the base plate 1 are required to be exactly located at the center position of the four vertical poles to achieve balanced transfer of the upper load. Therefore, before hoisting multiple base plates 1 at one time, the vertical pole points are first marked on the formwork to facilitate accurate hoisting.

[0075] S2: Make custom wire box 5;

[0076] Step S2 specifically includes:

[0077] S201: Prepare a wire box 501; the wire box 501 is an existing 86-type wire box with a size of 79mm*79mm*100mm;

[0078] S202: An L-shaped pull tab 502 is fixedly connected to each end of the wiring box 501. The L-shaped pull tab 502 includes a first pull tab 504 and a second pull tab 505 that are perpendicular to each other. One side of the first pull tab 504 is affixed to the side of the wiring box 501 and fixedly connected to the wiring box 501. At the same time, the second pull tab 505 is extended outward from the wiring box 501 and arranged horizontally to obtain the customized wiring box 5. The fixed connection method can be welding.

[0079] S3: Install and fix the customized junction box 5;

[0080] A hole is opened on the bottom plate 1, and the customized wire box 5 is placed in the hole. After the customized wire box 5 is placed in the hole, the second pull tabs 505 on both sides of the wire box 501 are attached to the top surface of the bottom plate 1, and the second pull tabs 505 are fixed to the bottom plate 1 by self-tapping screws 503 to form a three-dimensional fixing system. Figure 3 and Figure 4 shown.

[0081] In this way, a customized junction box 5 is designed and manufactured, and fixed to the inner structure of the base plate 1. During the wiring operation and equipment tightening during the water and electricity installation construction phase, quality defects such as displacement or inward collapse of the junction box 501 can be avoided.

[0082] The L-shaped pull tab 502 may be an elastic pull tab.

[0083] S4: Install the side wall glass magnesium board 3 and the top board 2;

[0084] Step S4 specifically includes: vertically installing the side wall glass magnesium board 3 between the bottom plate 1 and the top plate 2, so that the upper and lower sides of the side wall glass magnesium board 3 are respectively installed in the prefabricated card grooves at the ends of the top plate 2 and the bottom plate 1, and positioning the side wall glass magnesium board 3.

[0085] S5: Open holes on the side wall glass magnesium plate 3 on both sides of the secondary rib beam casting space 4;

[0086] Step S5 specifically includes: according to the electrical professional design drawings, using a hole opener to open holes on the side wall glass magnesium board 3, and the holes on the side wall glass magnesium board 3 on both sides of the secondary rib beam casting space 4 are opened symmetrically.

[0087] S6: Making a side wall glass magnesium plate positioning device 6;

[0088] Step S6 specifically includes:

[0089] S601: Prepare the components of the side wall glass magnesium plate positioning device 6, including the wire tube 601, the water stop gasket 602 and the connecting sleeve 603;

[0090] S602: Slide the water-stop gasket 602 onto the wire pipe 601 and securely connect it to the wire pipe 601. Figure 6shown.

[0091] In step S602 , the wire tube 601 and the water-stopping gasket 602 are made of metal, and the water-stopping gasket 602 is welded to the wire tube 601 .

[0092] S7: Install the side wall glass magnesium plate positioning device 6;

[0093] Step S7 specifically includes: passing one end of the two wire tubes 601 through the holes on the side wall glass magnesium board 3 on both sides of the secondary rib beam casting space 4, inserting the end of the wire tube 601 into the secondary rib beam casting space 4 from the inner side of the side wall glass magnesium board 3, placing the connecting sleeve 603 in the secondary rib beam casting space 4, inserting the ends of the two wire tubes 601 into the two ends of the connecting sleeve 603, and making the water stop gasket 602 contact with the side wall glass magnesium board 3. At this time, the water stop gasket 602 is in contact with the inner side of the side wall glass magnesium board 3; then fixing the two wire tubes 601 to the connecting sleeve 603, as shown in FIG. Figure 5 shown.

[0094] The inner side of the side wall glass magnesium board 3 refers to the side thereof facing the bottom plate 1 , and the outer side of the side wall glass magnesium board 3 refers to the side thereof facing the secondary rib beam casting space 4 .

[0095] In step S6, when manufacturing the side wall glass magnesium board positioning device 6, threaded holes 604 are pre-opened on the ends of the two wire tubes 601 and the connecting sleeve 603. In step S7, when installing the side wall glass magnesium board positioning device 6, the threaded holes 604 on the two are aligned, and then the tightening screws are screwed into the corresponding threaded holes 604 to fix the wire tube 601 and the connecting sleeve 603.

[0096] In this way, the connection point between the wire tube 601 and the connecting sleeve 603 is set in the middle of the secondary rib beam casting space 4. The wire tubes 601 on both sides cooperate with the water-stop gasket 602 to form a symmetrical pulling force on the side wall glass magnesium board 3, positioning the side wall glass magnesium board 3, and ensuring the accuracy of the secondary rib beam cross-sectional dimensions and the tightness of the sealing.

[0097] The side wall glass magnesium board 3 is made of high-precision board, which is seamlessly embedded with the bottom plate 1 and the top plate 2, so that the side wall glass magnesium boards 3 on both sides are of the same height, and the height of all the top plates 2 is consistent. In addition, the side wall glass magnesium boards 3 on both sides are symmetrically opened with a hole opener, which can ensure that the side wall glass magnesium boards 3 on both sides are still of the same height after the side wall glass magnesium board positioning device 6 is installed, and the height of all the top plates 2 is consistent, which is conducive to the subsequent pouring of secondary rib concrete. The top surface of all the top plates 2 is flush with the top surface of the secondary rib beam to form a complete horizontal surface.

[0098] S8: Check and recheck the side wall glass magnesium board 3 and the side wall glass magnesium board positioning device 6.

[0099] S9: Thread the wires into the line pipe 601 according to the electrical design drawings to complete the installation of the water and electricity pipelines.

[0100] Figure 6 Where D is the sum of the thickness of the side wall glass magnesium plate 3 and 1 / 2 of the secondary rib width.

[0101] The present invention constructs a three-dimensional fixing system by using L-shaped pull tabs 502 and self-tapping screws 503, thereby solving the problems of weak pre-embedded fixation and positioning deviation of the water and electricity terminal box 501 and improving the installation quality of the box 501.

[0102] The present invention adopts a high-precision seamless plate interlocking process, symmetrically opens holes on the side wall glass magnesium plates 3 on both sides of the secondary rib beam casting space 4, and cooperates with the side wall glass magnesium plate positioning device 6 to achieve bidirectional stress balance, thereby enhancing the overall sealing and structural integrity of the side wall glass magnesium plates 3, ensuring that the side wall glass magnesium plates 3 fit well with the top plate 2 and the bottom plate 1 and the joints are tight, solving the problems of loose joints between the side wall glass magnesium plates 3 and the top plate 2 and the bottom plate 1 and cracking of the side wall glass magnesium plates 3 during late groove opening, avoiding cracking of the side wall glass magnesium plates 3 due to pipeline groove opening in the late stage, ensuring the accuracy of the cross-sectional dimensions of the secondary rib beams around the cavity plate, ensuring that the cross-sectional dimensions of the secondary rib beams meet the design requirements, and at the same time ensuring the flatness of the top plate 2 and the secondary rib beams; and enhancing the sealing tightness with the water-stop gasket 602 to avoid the risk of leakage.

[0103] This invention optimizes the construction process, innovatively integrating pipeline pre-laying with a high-precision seamless plate-joining process to complete pipeline laying ahead of time and ensure plate fit. The unique symmetrical hole structure, supplemented by a sidewall magnesium glass plate positioning device (6) and a bidirectional stress balance system, is complemented by modular customized equipment and process reengineering technology. This technical system achieves millimeter-level positioning accuracy, effectively reducing common quality defects, effectively avoiding the risk of structural cracking, and eliminating potential leakage. It also provides precise controllable cross-sectional dimensions, reduces rework, improves efficiency, and shortens the construction period.
