Description

Technical Field

[0001] This utility model relates to an integrated building manhole, specifically a post-assembled integrated building manhole system, belonging to the field of integrated building manholes. Background Technology

[0002] Pipe shafts are independent building spaces that provide vertical pipelines for water, heating, electricity, air conditioning and other equipment inside buildings; ventilation shafts are enclosed spaces for ventilation or smoke exhaust in buildings. Whether it is a residential building, office building or factory, pipe shafts, ventilation shafts or even elevator shafts are all designed by designers who have considered factors such as structural bearing capacity, fire prevention, thermal insulation and sound insulation. They are formed by building structure professionals using reinforced concrete shear walls, masonry structures or lightweight partition walls, and are finished with internal plastering and painting. They form vertical spaces for equipment use and are an indispensable functional area of ​​the building as a whole. With the increasing number of intelligent building equipment, there will be more and more functional pipelines in buildings. From the design perspective of minimizing the fixed area of ​​the building, the internal space of the pipe shaft should be as small as possible. However, from the perspective of construction and maintenance, such narrow and limited space is very difficult to operate, making it difficult to guarantee the construction period and quality, and it is also difficult to achieve the aesthetic standards. Here are some problems that may be encountered in the design and construction of building pipe shafts: (1) Non-standard fireproof sealing: If the fireproof sealing around the pipe shaft is not done well, it may lead to the spread of fire. (2) Improper sleeve installation: No sleeve was installed when the water supply pipe passed through the floor, or the height of the sleeve did not meet the specifications. (3) Rough civil construction: The civil construction quality in the pipe well was rough and did not meet the requirements of fine treatment. (4) Garbage not cleaned in the pipe well: There may be garbage in the pipe well that was not cleaned in time, affecting the use and maintenance of the pipe well. (5) No fire collar for plastic drainage pipe in pipe well: The plastic drainage pipe used in the pipe well was not equipped with a fire collar, which increased the risk of fire. (6) Unreasonable pipe layout in pipe well: There may be problems with the pipe layout in the pipe well, such as the pipe spacing, the position of the fittings, and the height of the support. (7) Problems with the size design of pipe well: The size design of pipe well may not have taken into account the size of pipe fittings, installation requirements and the influence of structural beams and columns, resulting in insufficient actual usable space. (8) Chaotic construction sequence of pipe well: There are many overlapping construction procedures, which may lead to common quality problems. It is necessary to plan the construction sequence reasonably. Summary of the Invention

[0003] The purpose of this utility model is to design a post-assembled building integrated pipe well system, which can improve the operational difficulties caused by narrow space during pipe well construction, while taking into account daily maintenance and use, realizing the "standardized" construction and intelligent use of pipe wells in projects, and improving the quality and function of traditional building pipe wells.

[0004] The technical solution of this utility model is as follows:

[0005] A post-construction integrated manhole system, comprising a supporting casing system, a prefabricated manhole wall panel system, a solar lighting system, and a signage system.

[0006] The supporting sleeve system includes a supporting sleeve, a flame-retardant inner tube, and wedge-shaped clamps, used for positioning and fixing vertical pipes that pass through floors;

[0007] The supporting sleeve is an inverted conical structure pipe used to house and fix vertical pipes passing through floors in a pipe shaft; the bottom of the supporting sleeve is installed inside a reinforced concrete floor slab; the supporting sleeve is poured and fixed simultaneously with the floor slab structure; the height of the supporting sleeve is slightly higher than the thickness of the floor slab; the diameter of the supporting sleeve is larger than the diameter of the vertical pipe passing through the floor; multiple square slots are equidistantly provided on the inner wall of the supporting sleeve, and the slots are used to install and fix wedge-shaped clips;

[0008] The flame-retardant inner tube is used for vibration damping and fixation of the vertical pipe. The flame-retardant inner tube is sleeved inside the supporting sleeve. The flame-retardant inner tube has an inverted conical tube structure, consistent with the structure of the supporting sleeve. The flame-retardant inner tube has multiple strip-shaped openings. The strip-shaped openings correspond to the slots of the supporting sleeve. The height of the flame-retardant inner tube is the same as that of the supporting sleeve. The diameter of the flame-retardant inner tube is smaller than that of the supporting sleeve. The flame-retardant inner tube is integrally pressed from flame-retardant material.

[0009] The wedge-shaped clamp is placed in the supporting sleeve to secure the vertical pipe; the wedge-shaped clamp is a wedge-shaped structure with a right-angled triangle cross-section; a rubber pad is attached to the back of the wedge-shaped clamp for shock absorption; after the vertical pipe is inserted into and passes through the supporting sleeve, the position of the vertical pipe is adjusted, and the wedge-shaped clamp is inserted into the slot of the supporting sleeve to fix the vertical pipe.

[0010] The prefabricated assembled manhole wall panel system includes a water-retaining sill, assembled lightweight wall panels, and assembled manhole cover.

[0011] The water-retaining sill is a prefabricated fiber-reinforced concrete water-retaining sill used to outline the pipe shaft. The sill prevents water leakage, blocking external water from entering the pipe shaft or preventing water leaking from the pipe shaft from entering nearby floors. The sill has a rectangular cross-section, with several pre-drilled holes at the top and bottom. The pre-drilled holes at the top of the sill are connected to and fixed with prefabricated lightweight wall panels via keyways. The pre-drilled holes at the bottom of the sill are connected to pre-drilled holes in the lower floor slab via keyways, and after accurate installation, are connected and fixed to the lower floor slab structure via grouting. The top of the sill is used to install and fix prefabricated lightweight wall panels.

[0012] The water-retaining sill is connected to the lower structural floor slab and prefabricated lightweight wall panels by mortar to form an integral whole.

[0013] Furthermore, the pin key is a threaded steel bar, a universal connector used to connect water-retaining sills, prefabricated lightweight wall panels, floor slabs, etc.

[0014] The prefabricated lightweight wall panels are used to construct pipe wells, and there are several of them. The prefabricated lightweight wall panels are lightweight wall panels with vertical tenons and mortises on both sides of the wall. The tenons and mortises are respectively provided with grouting holes for key pins. There are several grouting holes. The tenons are used to insert into the mortises of prefabricated lightweight wall panels with the same structure. Before inserting the tenons, key pins are first inserted into the grouting holes of the tenons. Then, the other end of the key pins is aligned with the grouting holes of the mortises of the prefabricated lightweight wall panels with the same structure, and then the connection is made.

[0015] The prefabricated lightweight wall panel has pre-drilled holes on both the upper and lower sides; the pre-drilled holes on the upper part of the prefabricated lightweight wall panel are connected to the upper floor slab by key; the pre-drilled holes on the lower part of the prefabricated lightweight wall panel are connected to the pre-drilled holes on the upper part of the water-retaining sill by key.

[0016] The inner wall panel of the prefabricated lightweight wall panel is also pre-embedded with a horizontal steel flat strip. The steel flat strip is provided with several evenly distributed holes, which are used to fix the wire trough or cable tray.

[0017] The width of the steel flat strip is between 10mm and 25mm, and the length of the steel flat strip is the same as the width of the prefabricated lightweight wall panel.

[0018] The joints between the prefabricated lightweight wall panels are filled with lightweight foamed mortar.

[0019] The prefabricated lightweight wall panels are preferably made of lightweight concrete strips or rock wool sandwich metal panels; lightweight concrete strips are mostly used for pipe shafts in residential, hotel, teaching, research and office buildings; rock wool sandwich lightweight panels are used for pipe shafts in industrial buildings such as factories.

[0020] The prefabricated manhole cover is a precast reinforced concrete cover plate, which is installed on the top of the manhole above the roof. The prefabricated manhole cover plate is equipped with a solar photovoltaic panel, which is used for energy storage in the lighting system inside the manhole.

[0021] The solar lighting system includes solar photovoltaic panels, batteries, lights, sensors, and sensor-activated doorplates. The solar photovoltaic panels are located on a prefabricated cover plate at the top of the pipe shaft. The batteries are connected to the lights, sensors, and sensor-activated doorplates on each floor via cables. The lights and sensors are located in the pipe shaft on each floor. The sensor-activated doorplates are located on the fire doors of the pipe shaft. When the fire door of the pipe shaft is opened, the lights turn on and the sensor-activated doorplates turn off. When the fire door is closed, the lights inside the pipe shaft turn off, and the sensor-activated doorplates on the top of the fire door turn on.

[0022] The identification system includes anti-static pipe markings, water flow indicator lights, and induced current indicators;

[0023] The anti-static pipeline markings are made of anti-static materials and are capable of preventing static electricity. The surface of the anti-static pipeline markings is affixed with reflective stickers. The anti-static pipeline markings are affixed to the surface of vertical pipelines to display the attributes of the vertical pipelines, such as fire water supply, greywater, domestic water, and water flow direction. When the fire door of the pipeline shaft is opened, the text information on the anti-static pipeline markings is reflected and displayed under the illumination of the lighting. After the fire door is closed, the anti-static pipeline markings are "dormant".

[0024] The water flow indicator light is installed on the vertical pipe used for water supply to display the water flow status within the pipe. The indicator light uses light changes to show the water flow status and consists of an LED light and a sensor. It can automatically sense the size and speed of the water flow and reflect the flow status through light changes. The induced current indicator is installed on the cable tray fixed to the evenly distributed holes to monitor the current status of the cables within the cable tray.

[0025] The beneficial effects of this utility model are as follows:

[0026] (1) Spatial standardization. The pipe positioning and spacing (the accurate location of the pipes passing through the floor slab or wall for the pre-embedded sleeves) are accurate, the pipe shaft wall panel is square and the internal size is appropriate; the arrangement and positioning of pipeline equipment in the pipe shaft are economical and reasonable; the installation and operation are convenient; for a certain unit project, the pipe shafts and ventilation shafts on each floor can achieve "standardized" assembly construction;

[0027] (2) Simplified fixing. The use of "load-bearing sleeves" to work together with the structural floor slab and fix the pipeline at the root avoids the need for additional (dragging) supports and facilitates fireproof sealing; the prefabricated lightweight wall panels increase the lateral support and fixing points for pipelines such as cable trays, which not only facilitates pipeline laying but also promotes standardization;

[0028] (3) Prefabricated wall panels. The space enclosure structure adopts prefabricated prefabricated strip panels or rock wool sandwich decorative partition panels with integrated decoration and lightweight thermal insulation and sound insulation (such as ceramsite concrete). The inner surface is painted and decorated before installation. Compared with the traditional masonry structure, it reduces the labor intensity and eliminates the backward process of large-scale manual work of building and plastering ventilation shafts. The thinner panel thickness saves the space used. Only the "functional panel joints" are treated, eliminating a lot of decoration and shortening the construction period.

[0029] (4) The construction sequence of "exterior first, interior second" and "civil engineering first, installation second" was optimized to "interior first, exterior second" and "installation first, civil engineering second", which improved the working conditions and operating environment. Furthermore, the interior decoration of the civil engineering pipe shaft was made of prefabricated assembly, which ensured the fine detail of the civil engineering professional. The partition wall of the pipe shaft enclosure structure was assembled and sealed after the pipe equipment was installed, which ensured the working space required for the plastering, painting, pipe decoration, fireproofing, and even the installation of fire collars on the ceiling, floor, and walls of the pipe shaft or ventilation shaft. This transformed the operation in the narrow and limited space into normal installation operation, improved the construction quality inside the pipe shaft or ventilation shaft, and accelerated the progress.

[0030] (5) Improved lighting and improved usage environment. The post-assembled pipe well has introduced solar daylights into the wall panels of each floor, which solves the problem of lack of lighting in public hidden areas or the problem of energy-saving management of lighting in traditional pipe wells, and provides conditions for checking water and electricity meters; at night, induction light tubes are used for emergency lighting; the pipe well has achieved good lighting, clear signage and convenient use, maintenance and repair.

[0031] (6) Post-assembled pipe wells facilitate the cleaning of waste during construction;

[0032] (7) The top plate of the pipeline well is an open top plate, which facilitates the laying of cables with larger diameters, reduces labor intensity, and is conducive to inspection and maintenance.
