Technical Field

[0001] The invention belongs to the technical field of assembled buildings, and in particular relates to an autoclaved aerated concrete slab and a wiring channel forming process thereof. Background Art

[0002] In the prior art, partition boards are mainly used as prefabricated wall panels in non-load-bearing parts of indoor areas. They are mainly used as indoor partition walls to separate indoor spaces and provide sound insulation. At the same time, when some partition boards are used, some partition boards are pre-buried with pipelines by cutting and grooving on site, which is time-consuming and labor-intensive.

During the wall production process, the wire box and the core-penetrating tube are pre-embedded, and then the core-penetrating tube is fixed by the steel support, and then the position of the wire box is fixed by the steel structure, and then the electrical conduit is directly inserted into the wire box by the core-penetrating tube, and the pre-embedding of the electrical conduit box is completed.

[0004] In this patent, a through-core tube is pre-buried during the processing of the partition board to form a wiring channel for the layout of the electrical pipe. The layout of the through-core tube will greatly increase the processing cost.

[0031] Example 1

[0032] like Figure 2 As shown, a kind of autoclaved aerated concrete strip board includes a wire box 2 and a wall panel body. The wall panel body includes a plurality of partition boards 1. Each partition board 1 is arranged in sequence along the vertical direction. A plurality of transverse wiring channels with a cavity structure are provided in each partition board 1. Each transverse wiring channel is divided into a first-section wiring channel 3 and a last-section wiring channel 4. Among them, the top of the first-section wiring channel 3 is provided with a wire box installation groove connected thereto. The wire box 2 is embedded in the wire box installation groove. The first-section wiring channel 3 is connected to the outside world through the wire box 2. The bottom wire opening of the last-section wiring channel 4 is arranged on the bottom surface of the corresponding partition board 1 and is connected to the outside world. A connecting groove 5 is provided between the first-section wiring channel 3 and the last-section wiring channel 4, which is used to realize the connection between the first-section wiring channel 3 and the last-section wiring channel 4, so that the wires can be arranged and routed in the first-section wiring channel 3 and the last-section wiring channel 4.

[0033] In this embodiment, there are two partition boards 1, namely, an upper first partition board 1 and a lower second partition board 1. The first section wiring channel 3 and the last section wiring channel 4 are respectively arranged on the first partition board 1 and the second partition board 1.

[0034] In this embodiment, there are two first-section wiring channels 3 on the first partition board 1, and they are arranged at intervals along the horizontal direction.

[0035] The connection groove 5 is provided on the top of the second partition board 1 and is a notch structure with an open top. The connection groove 5 is connected to the first wiring channel 3 on the first partition board 1, so that the wires in the first wiring channel 3 can be gathered at the connection groove 5 and pass through the last wiring channel 4.

[0036] In this embodiment, the first section wiring channel 3 and the last section wiring channel 4 are both arranged in the center of the thickness direction of the corresponding partition board 1. The cross-sections of the first section wiring channel 3 and the last section wiring channel 4 have circular, elliptical, square, rectangular, diamond and other shapes, which can adapt to the wiring of wires of different shapes.

[0037] like Figure 1 As shown, the wiring channel forming process of the partition board in this embodiment has the following specific steps: S1, skeleton construction, according to the size of each partition board to be constructed, manually tie the steel mesh sheets of corresponding size. Multiple transverse plug rods arranged along the transverse direction are detachably fixed to the corresponding transverse steel bars through clamps. Tie the wire box model to the corresponding transverse plug rod. Among them, the wire box model is made of water-soluble material.

[0038] S2, pouring, pouring the concrete slurry automatically mixed by the autoclaved aerated concrete raw materials into the constructed mold.

[0039] S3, insert the skeleton, insert the multiple steel mesh sheets of the binding wire box model into the mold after casting through the inserter, and transport them together with the mold to the curing room for gasification and initial condensation to form a blank body. The temperature in the curing room is 40~45℃, and the static time is 180~240min. The wire box model made of water-soluble material softens during the static process.

[0040] S4, pulling out the horizontal plug rod inserted in the blank body. The hole left by pulling out the horizontal plug rod is a horizontal wiring channel for arranging the wires.

[0041] S5, demoulding, the blank body after resting is transferred to the cutting area. The flip demoulding mechanism flips the blank body 90 degrees and places it on the trolley. After it is placed stably, the flip demoulding mechanism grabs the mold of the blank body except the bottom surface and disassembles and separates it.

[0042] S6, segmentation, the blank body is driven by the trolley to pass through the vertical cutting device and the horizontal cutting device in turn, and vertical and horizontal cutting processes are performed. Through the vertical cutting process, the excess waste material of the blank body in the length direction is removed. Through the horizontal cutting process, the blank body will be sequentially segmented into multiple segmented blanks with the same thickness as the required partition board. During the horizontal cutting process, the wire box model part set between two adjacent segmented blanks will be split in half along the middle to form two wire box installation grooves set in the two segmented blanks. At the same time, the side of the segmented blank is grooved to form a concave connecting groove.

[0043] S7, edge trimming, the split blank that has been split is carried by a trolley and passes through the top suction device and air blowing device in turn to remove the waste on the top and bottom edges of the partition board. The split blank that has completed the bottom edge trimming is transferred to the turning table by a trolley and turned 90°. With the cooperation of the edge cleaning machine, the waste on the side and bottom of the split blank is removed to form a finely trimmed blank.

[0044] S8, high temperature steam curing, the refined green body is turned over by the turning table, returned to the trolley, and transported to the autoclave for autoclave treatment. During the autoclave process, the temperature in the autoclave is 150~200℃, and the pressure is 8~13 standard atmospheres. The entire autoclave lasts for 8~12 hours. The wire box model after the refined green body is softened forms pulp under high humidity and high temperature and is applied to the corresponding channel wall.

[0045] S9, clean the wiring channel, use a flexible drilling machine or steel chisel with a length of 3.5~6.5m and a diameter of 15~60mm to clean along the hole wall of the wiring channel, remove the pulp residue attached to the hole wall, and connect it with each wiring channel to form a finished partition board. Among them, the flexible drilling machine uses Yongsheng 80 type pipeline dredging machine.

[0046] S10, output placement, the finished partition boards that have been cleaned are hoisted and stacked, and the separated molds are transported to the mold-closing area by a trolley for cleaning and mold-closing and wait for reuse.

Each partition board 1 is arranged in sequence along the horizontal direction, and each has a wiring channel with a cavity structure. A wire box installation groove connected to the wiring channel is provided in the middle of the wiring channel. The wire box 2 is embedded and fixed in the wire box installation groove.

[0049] like Figure 1 As shown, the wiring channel forming process of the partition board in this embodiment has the following specific steps: S1, skeleton construction, according to the size of each partition board to be constructed, manually tie the steel mesh sheets of corresponding size. Multiple transverse plug rods arranged along the horizontal direction are detachably fixed to the corresponding transverse steel bars through clamps. Tie the paper stick and the wire box model to the corresponding transverse plug rod. Among them, the wire box model is made of water-soluble material. The length direction of the paper stick is perpendicular to the length direction of the transverse plug rod. The paper stick uses a hollow paper stick with a cross-sectional diameter of 15~60mm (the hole formed by the paper stick with a diameter of 15 can pass 2 wires, the hole formed by the paper stick with a diameter of 20 can pass 4 wires, and so on). The end of the paper stick is covered with a plastic film, which can effectively prevent the softening of the paper stick due to excessive external humidity under normal temperature environment, which affects the formation of the longitudinal wiring channel. The setting of the plastic film ensures that the paper stick can only be dissolved and softened in an environment of high temperature and high pressure (temperature of 150~200℃, pressure of 8~13 standard atmospheres), thus ensuring the smooth formation of the longitudinal wiring channel and the wire box installation groove.

[0050] S2, pouring, pouring the "slurry" automatically mixed by the autoclaved aerated concrete raw materials into the constructed mold.

[0051] S3, insert the skeleton, insert the multiple steel mesh sheets of the wire box model into the mold after casting through the inserter, and transport them together with the mold to the curing room for gasification and initial condensation to form a blank. The temperature in the curing room is 40~45℃, and the static time is 180~240min. The paper stick and wire box model soften during the static process.

[0052] S4, pulling out the horizontal insertion rod inserted on the blank body. The hole left by pulling out the horizontal insertion rod is the horizontal wiring channel.

[0053] S4, demoulding, transfer the blank body after resting to the cutting area. The flip demoulding mechanism flips the blank body 90° and places it on the trolley. After it is placed stably, the flip demoulding mechanism grabs the mold of the blank body except the bottom surface and disassembles and separates it.

[0054] S5, segmentation, the blank body is driven by the trolley to pass through the vertical cutting device and the horizontal cutting device in turn, and vertical and horizontal cutting processes are performed. Through the vertical cutting process, the excess waste material of the blank body in the length direction is cut off. Through the horizontal cutting process, the blank body will be sequentially segmented into multiple segmented blanks with the same thickness as the required partition board. During the horizontal cutting process, the wire box model part set between two adjacent segmented blanks will be split in half along the middle to form two wire box installation grooves set in the two segmented blanks.

[0055] S6, edge trimming, the finished split blank is carried by a trolley, passes through the top suction device and the air blowing device in turn, and the waste on the top and bottom edges of the partition board is removed in turn. The split blank that has completed the bottom edge trimming is transferred to the turning table by a trolley and turned 90°. With the cooperation of the edge cleaning machine, the waste on the side and bottom of the split blank is removed to form a finely trimmed blank.

[0056] S7, high temperature steam curing, the refined green body is turned over by the turning table and returned to the trolley, and then transported to the autoclave for autoclave treatment. During the autoclave process, the temperature in the autoclave is 150~200℃ and the pressure is 8~13 standard atmospheres. The entire autoclave takes 8~12 hours. After the refined green body is softened, the paper stick and wire box model are formed into pulp under high humidity and high temperature and applied to the corresponding channel wall.
