Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and specifically discloses a construction method for pre-embedding assembled lightweight partition wall pipelines. Background Art

[0002] Traditional high-energy and high-consumption construction technologies will generate a large amount of construction waste during the construction process, which will cause waste and damage to the ecological environment and is not conducive to sustainable economic development. Accelerating the promotion and development of building industrialization technology and enabling the sustainable and healthy development of prefabricated industrialized building technology can effectively improve the problems existing in traditional construction technology. Prefabricated concrete component (PC component) technology is widely used in prefabricated buildings, that is, the pre-made PC components such as beams, slabs, columns and walls are transported to the construction site and then assembled. The existing pre-buried construction method of prefabricated lightweight partition wall pipelines is traditional in design and mainly based on traditional decoration. The interior industrialization technology has not yet been fully popularized and promoted. After pre-buried, it is not standardized enough, and there are hidden dangers of inconsistent construction standards and low construction accuracy, which is not convenient for later maintenance. Summary of the invention

[0003] The present invention provides a method for pre-embedding construction of assembled lightweight partition wall pipelines in advance, so as to improve the problem that the existing method for pre-embedding construction of assembled lightweight partition wall pipelines is traditionally designed, is not standardized after pre-embedding, is prone to the hidden dangers of inconsistent construction standards and low construction accuracy, and is not convenient for later maintenance.

[0004] The above-mentioned pre-buried construction method of assembled lightweight partition wall pipelines comprises the following steps:

[0005] S1. Design the location of electrical pipelines, water supply and drainage pipelines, and heating pipelines

[0006] According to the size of the prefabricated partition wall, design the positions of the embedded parts and reserved holes on the prefabricated partition wall drawings;

[0007] When the horizontal pipelines of electrical pipelines must be concealed, they shall be laid in the cast-in-place layer of the composite floor;

[0008] The main pipes for water supply and drainage are pre-buried and drainage holes are reserved;

[0009] S2, pre-buried electrical pipelines, water supply and drainage pipelines, and heating pipelines

[0010] The electrical pipelines are cast in the prefabricated partition walls. Based on the principle of the shortest pipeline, the electrical embedded parts close to the ground are connected downwards to the pipelines in the cast-in-place layer, and the electrical embedded parts close to the floor are connected upwards to the pipelines in the cast-in-place layer.

[0011] When laying drainage pipes in different layers and using composite floor slabs, make secondary holes of the same specifications in the cast-in-place layer at the construction site according to the drainage pipe holes on the prefabricated partition wall drawings;

[0012] The water supply pipeline should be laid openly under the indoor floor, in the cushion layer of the floor or ground, or in the pipe groove along the wall, and the water supply point should be avoided from being set on the prefabricated shear wall;

[0013] According to the position of the support brackets of radiators of different forms or radiators of the same form but different numbers of radiators, the setting rules are summarized, and the specifications of prefabricated partitions are standardized by increasing the number of embedded bolt holes. Cement mortar or pebble concrete is used as the filling layer for fixing the radiator, and on-site filling is carried out. Pre-set groove insulation panels and pre-set thin heating panels are prefabricated in the factory, made into panels according to size, assembled on-site, and the floor heating pipeline cushion layer is laid.

[0014] In step S1, for sockets, indoor distribution lines, and indoor distribution boxes, since the corresponding electrical pipelines are laid downward from the equipment to the cast-in-place layer in the floor slab of this layer, they are connected to the horizontally arranged electrical pipelines in the cast-in-place layer to ensure that the electrical pipelines can be smoothly connected. During the design, electrical pipeline connection holes are left at the connection below the prefabricated partition wall.

[0015] In step S1, the embedded parts and reserved holes are integrated on a drawing to check for omissions and gaps and to check whether there are conflicts between the positions of the embedded parts and the reserved holes and whether the pipeline paths overlap. If any problems are found, they are solved to avoid the phenomenon of cross-laying of multiple electrical pipelines at the same location.

[0016] In step S1, a BIM drawing is generated for the prefabricated partition wall and the embedded parts and reserved holes set on the prefabricated partition wall, and provided to the prefabricated component factory. The prefabrication personnel reserve and embed the embedded parts and reserved holes in each prefabricated partition wall according to the BIM drawing.

[0017] In step S2, when a secondary hole of the same specification is reserved in the cast-in-place layer at the construction site, the diameter of the reserved hole is 50 mm to 100 mm larger than the outer diameter of the drainage pipe.

[0018] The above-mentioned pre-buried construction method for assembled lightweight partition wall pipelines also includes step S3, which is performed simultaneously with step S2 or staggered, and the lightning protection and grounding pre-buried

[0019] Install lightning arresters on the roof, use the steel bars in the frame columns or shear walls as lightning protection down conductors, and use the steel bars in the building foundation as grounding electrodes;

[0020] When the steel bars in the frame column are used as lightning protection down conductors, sleeve grouting or grout anchor lap connection is used at the connection, and steel bars of the same cross-sectional area are used for bridging at the connection to achieve the purpose of electrical penetration;

[0021] When the steel bars in the shear wall are used as lightning protection down conductors, the vertical steel bars in the shear wall are connected by sleeve grouting or grout-anchor lap connection according to different parts;

[0022] The main reinforcement of the composite beam that meets the lightning protection requirements is used as a pressure equalizing ring;

[0023] The ring beam is a steel structure and is reliably connected during construction, and the steel structure ring beam of each floor is directly used as a pressure equalizing ring.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The above-mentioned pre-embedded construction method for prefabricated lightweight partition walls accurately locates each embedded part and reserved hole in the design stage and generates a BIM drawing together with the prefabricated partition wall and provides it to the prefabricated component factory. The prefabrication personnel follow the drawings and the unified standards to accurately locate and reserve and embed the wires, boxes, casings, holes, etc. in each prefabricated partition wall, which is convenient for construction and future maintenance.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] This embodiment provides a construction method for pre-embedding pipelines in an assembled lightweight partition wall, comprising the following steps.

[0030] S1. Design the location of electrical pipelines, water supply and drainage pipelines, and heating pipelines

[0031] According to the size of the prefabricated partition wall, design the positions of the embedded parts and reserved holes on the prefabricated partition wall drawings;

[0032] When the horizontal pipelines of electrical pipelines must be concealed, they shall be laid in the cast-in-place layer of the composite floor;

[0033] The main pipes for water supply and drainage are pre-buried and drainage holes are reserved. Designers must accurately locate each drainage pipe hole on the prefabricated partition wall drawings.

[0034] In step S1, for sockets, indoor distribution wires, and indoor distribution boxes, since the corresponding electrical pipelines are laid downward from the equipment to the cast-in-place layer in the floor slab of this layer, and connected with the electrical pipelines arranged horizontally in the cast-in-place layer to ensure smooth connection between the electrical pipelines, electrical pipeline connection holes are reserved at the connection below the prefabricated partition wall during design. Sockets, switches, weak current equipment, fire-fighting equipment, etc. installed on the prefabricated partition wall need to reserve junction boxes in advance during the design stage, and standard 86-type junction boxes are preferably used.

[0035] In step S1, the embedded parts and the reserved holes are integrated on a drawing to check for omissions and gaps and to check whether there are conflicts between the points of the embedded parts and the reserved holes and whether the pipeline paths overlap. If any problems are found, they are resolved.

[0036] In step S1, when the horizontal electrical pipelines must be concealed, they are laid in the cast-in-place layer of the composite floor slab using a variety of methods including BIM technology to carry out three-dimensional pipeline comprehensive design to avoid the phenomenon of cross-laying of multiple electrical pipelines at the same location.

[0037] In step S1, a BIM drawing is generated for the prefabricated partition wall and the embedded parts and reserved holes set on the prefabricated partition wall, and provided to the prefabricated component factory. The prefabrication personnel reserve and embed the embedded parts and reserved holes (including wires, boxes, cabinets, sleeves, holes, etc.) in each prefabricated partition wall according to the BIM drawing and unified standards.

[0038] S2, pre-buried electrical pipelines, water supply and drainage pipelines, and heating pipelines

[0039] The electrical pipelines are cast in the prefabricated partition walls. Based on the principle of the shortest pipeline, the electrical embedded parts close to the ground are connected downwards to the pipelines in the cast-in-place layer, and the electrical embedded parts close to the floor are connected upwards to the pipelines in the cast-in-place layer.

[0040] When drainage pipelines are laid on different layers and composite floor slabs are used, holes should be left on the prefabricated composite slabs for each drainage point in the prefabricated component factory according to the accurately positioned prefabricated partition wall drawings. At the construction site, secondary holes of the same specifications should be left in the cast-in-place layer according to the drainage pipe holes on the prefabricated partition wall drawings. The diameter of the reserved holes should be 50mm to 100mm larger than the outer diameter of the drainage pipe.

[0041] The water supply pipeline is laid openly under the indoor floor, in the cushion layer of the floor or ground, or in the pipe groove along the wall. Closely cooperate with the construction professionals to adjust the room layout to avoid setting the water supply point on the prefabricated shear wall;

[0042] According to the position of the support brackets of radiators of different forms or radiators of the same form but different numbers of radiators, the setting rules are summarized, and the specifications of prefabricated partitions are standardized by increasing the number of embedded bolt holes. Cement mortar or pebble concrete is used as the filling layer for fixing the radiator, and on-site filling is carried out. Pre-set groove insulation panels and pre-set thin heating panels are prefabricated in the factory, made into panels according to size, assembled on-site, and the floor heating pipeline cushion layer is laid.

[0043] Step S3: Lightning protection and grounding pre-embedded

[0044] Step S3 and step S2 are performed simultaneously or alternately.

[0045] The lightning protection design must first determine the lightning protection level, and then take corresponding lightning protection measures. Lightning protection measures are divided into external lightning protection measures, internal lightning protection measures and protection against lightning electromagnetic pulses.

[0046] In this embodiment, a lightning rod is arranged on the roof, and the steel bars in the frame column or the shear wall are used as the lightning protection down conductor, and the steel bars in the building foundation are used as the grounding electrode; when the steel bars in the frame column are used as the lightning protection down conductor, the connection is made by sleeve grouting connection or grout anchor overlap connection, and at the same time, steel bars of the same cross-sectional area are used for bridging at the connection to achieve the purpose of electrical continuity; when the steel bars in the shear wall are used as the lightning protection down conductor, the connection of the vertical steel bars of the shear wall is made by sleeve grouting connection or grout anchor overlap connection according to different parts; the main reinforcement of the composite beam that meets the lightning protection requirements is used as the equalizing ring; the ring beam is a steel structure and can be reliably connected during construction, and the steel structure ring beam of each layer is directly used as the equalizing ring.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
