[0002] Large-story residential shops usually refer to building spaces with floor heights exceeding conventional standards (such as 3 meters). The advantages of large-story buildings are a stronger sense of space, greater flexibility, and good ventilation and lighting.

[0003] While large-story buildings have their advantages, the construction of large-story secondary structural walls (such as autoclaved aerated concrete walls) has become a major and difficult point in construction. Autoclaved aerated concrete walls are made of autoclaved aerated concrete (ALC) strips, and the secondary structure ALC strips are often hoisted by large machinery such as truck cranes; concrete structural columns and ring beams are set as the post-cast concrete frame support system to prevent cracking and overturning caused by the autoclaved aerated concrete (ALC) strips being too high.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-7 This application is described in further detail.

[0036] The embodiments of the present application disclose a large-height ALC wall, a construction device and a construction method thereof.

[0037] Example 1 The present application embodiment discloses a large-height ALC wall, referring to Figure 1 , a large-layer high autoclaved aerated concrete wall is arranged on the structural plane of the concrete frame structure 1; in the present embodiment, the large-layer high autoclaved aerated concrete wall is arranged on the first floor of the building, and the height of the first floor of the building is generally greater than 3m, so as to improve the sense of space of the first floor of the building; in the present embodiment, the height of the first floor of the building is 6m; the concrete frame structure 1 includes a first floor slab 11, a second floor slab 12, and a shear wall 13 arranged between the first floor slab 11 and the second floor slab 12.

[0038] Reference Figure 1 The high-rise ALC wall includes a frame keel support system 2 and autoclaved aerated concrete strips 3.

[0039] Reference Figure 1The frame keel support system 2 is fixedly connected to the concrete frame structure 1, and the frame keel support system 2 divides the structural plane into a plurality of secondary structural unit planes arranged in a matrix; a plurality of autoclaved aerated concrete slats 3 are provided, and the autoclaved aerated concrete slats 3 are vertically arranged, and a plurality of autoclaved aerated concrete slats 3 are spliced ​​and fixed to the secondary structural unit plane, and the autoclaved aerated concrete slats 3 are fixedly connected to the frame keel support system 2 and the concrete frame structure 1.

[0040] Reference Figure 1 Specifically, the keel support system includes embedded parts 21, a frame keel body 22 and a hanger 23.

[0041] Reference Figure 1 The staff sets a plurality of embedded parts 21 at the installation position of the frame keel body 22, and the plurality of embedded parts 21 are fixedly connected with the first floor slab 11, the second floor slab 12 and the shear wall 13 through chemical bolts.

[0042] Reference Figure 1 The keel body includes a plurality of vertical square steel keels 222 and horizontal square steel keels 221 arranged at intervals. The vertical square steel keels 222 and the horizontal square steel keels 221 are fixedly connected. The vertical square steel keels 222 and the horizontal square steel keels 221 are surrounded by the concrete frame structure 1 to form a secondary structural unit plane. The ends of the vertical square steel keels 222 and the horizontal square steel keels 221 are welded and fixed to the embedded parts 21, thereby realizing the fixed connection between the frame keel body 22 and the concrete frame structure 1. In this embodiment, the frame keel body 22 divides the large-story high autoclaved aerated concrete wall into four small rectangular unit planes, thereby reducing the size of a single autoclaved aerated concrete strip 3.

[0043] Reference Figure 1 The suspension rod 23 is arranged between the second dragon board and the horizontal square steel keel 221. The suspension rod 23 is arranged vertically. One end of the suspension rod 23 is fixedly connected to the horizontal square steel keel 221, and the other end of the suspension rod 23 is fixedly connected to the concrete frame structure 1. In this embodiment, the suspension rod 23 is fixed to the second floor slab 12 and the horizontal square steel keel 221 by matching nuts. The length of the screw is adjusted by tightening the nut, and the horizontal keel is arched by 3‰. The reaction force on the arched horizontal square steel keel 221 offsets the excessive downward bending and deflection of the horizontal square steel keel 221 after the autoclaved aerated concrete strip 3 is installed, so as to avoid the first-floor strip being damaged due to excessive pressure.

[0044] Reference Figure 1 and Figure 2 The staff uses a special construction device to hoist the autoclaved aerated concrete slab 3 to the plane of the second-floor structural unit, and fixes the autoclaved aerated concrete slab 3 to the horizontal square steel keel 221, the vertical square steel keel 222, the first floor slab 11, the second floor slab 12 and the shear wall 13.

[0045] Reference Figure 1 and Figure 2 In order to facilitate the installation and fixation of the autoclaved aerated concrete strip 3 and the frame keel body 22, through angle steels 24 are welded on the upper and lower sides of the horizontal square steel keel 221, and the autoclaved aerated concrete strip 3 is fixedly connected to the angle steel 24 and the horizontal square steel keel 221 using hook bolts 25.

[0046] The implementation principle of a large-height ALC wall in the embodiment of the present application is: Reference Figure 1 and Figure 2 , the large-layer high autoclaved aerated concrete wall is divided into several secondary structural unit planes through the frame keel support system 2, thereby reducing the height of a single autoclaved aerated concrete strip 3. On the one hand, the workers use small construction devices to strip the autoclaved aerated concrete strips with smaller sizes, which is convenient for the workers to construct and improve the construction efficiency of the autoclaved aerated concrete wall; at the same time, the autoclaved aerated concrete strips 3 with smaller sizes can prevent cracking, overturning and damage of the autoclaved aerated concrete wall, thereby improving the construction quality.

[0047] Example 2 This embodiment 2 discloses a construction device for a large-height ALC wall, and the construction device is used to hoist the autoclaved aerated concrete slab 3 to the plane of the second-floor structural unit.

[0048] Reference Figure 3 and Figure 4 The construction device includes a frame 4, a moving mechanism 5, a lifting mechanism 6, a guide assembly 7 and a counterweight block 8.

[0049] Reference Figure 3 and Figure 4 The frame 4 includes a frame body 41, a lifting gantry 42 and a person-entering assembly 43. The lifting gantry 42 is fixedly mounted on one side of the frame body 41; one end of the person-entering assembly 43 is fixedly connected to the frame body 41, and the other end of the person-entering assembly 43 is fixedly connected to the lifting gantry 42. Specifically, the person-entering assembly 43 includes a fixedly connected staircase 431, a handrail 432 and a person-entering platform 433; the staircase 431 is tiltedly arranged between the frame body 41 and the lifting gantry 42, and the handrail 432 is fixedly arranged on both sides of the staircase 431; the person-entering platform 433 is arranged horizontally, and the person-entering platform 433 is fixedly arranged between the staircase 431 and the bracket of the lifting gantry 42. By arranging the person-entering staircase 431 and the person-entering platform 433, the staff can assist in installing the autoclaved aerated concrete slab 3 of the plane of the high-rise secondary structure unit on the frame 4, thereby facilitating the construction of the staff.

[0050] In this embodiment, the frame 4 is formed by welding steel pipes; in other embodiments, the frame 4 may be formed by fixing steel pipes and scaffolding connectors.

[0051] Reference Figure 3 and Figure 4 The moving mechanism 5 is fixedly connected to the frame 4 , and the moving assembly includes a plurality of universal wheels 51 , which are fixedly connected to the frame body 41 .

[0052] Reference Figure 3 and Figure 4 The lifting mechanism 6 includes a winch 61 and a fixed pulley 62. The winch 61 is fixed on the frame body 41, and the fixed pulley 62 is fixed on the lifting gantry 42. The steel strand 611 of the winch 61 is wound around the fixed pulley 62 and fixedly connected to the autoclaved aerated concrete slat 3. The winch 61 is used to lift the autoclaved aerated concrete slat 3 to the plane of the secondary structure unit.

[0053] Reference Figure 3 and Figure 4 The guide assembly 7 includes at least two vertically arranged guide rods 71, which are fixedly connected to the frame body 41 and the lifting gantry 42, and a plurality of guide rods 71 ​​form a guide surface; on the vertical projection plane, an avoidance gap is provided between the guide rods 71 ​​and the fixed pulley 62, and the guide rods 71 ​​are used to abut against the autoclaved aerated concrete strip 3; the counterweight block 8 is arranged in the frame body 41, and the counterweight block 8 is arranged on the side of the frame body 41 away from the lifting gantry 42.

[0054] The implementation principle of the construction device of a large-height ALC wall in the embodiment of the present application is as follows: Reference Figure 3 and Figure 4 , the lifting mechanism 6 lifts the horizontally arranged autoclaved aerated concrete strip 3 vertically; then, the autoclaved aerated concrete strip 3 abuts against the vertically arranged guide assembly 7, thereby straightening the autoclaved aerated concrete strip 3, so that the autoclaved aerated concrete strip 3 is arranged vertically, thereby facilitating the staff to pre-install the vertically arranged autoclaved aerated concrete strip 3 at the plane of the second-floor structural unit, thereby improving the installation efficiency of the autoclaved aerated concrete wall. In addition; the guide rod 71 in the guide assembly 7 has a limiting effect on the autoclaved aerated concrete strip 3, which can reduce the autoclaved aerated concrete strip 3 from being tilted and clamped in the frame 4 during the lifting process, so as to facilitate the staff to lift the autoclaved aerated concrete strip 3.

[0055] Example 3 The difference between this embodiment 3 and embodiment 1 is that: Reference Figure 5 and Figure 6Since the frame 4 needs to be stepped on by a person, and the height difference between the stepping plane and the ground is large, the frame 4 needs good stability. When the staff installs the second layer of autoclaved aerated concrete slats 3, the staff needs to stand on the stepping platform 433 to assist the autoclaved aerated concrete slats 3 to move the second layer of the second layer structural unit plane; this makes the mass of the construction device on this side large, and there is a tendency to overturn. Therefore, this embodiment further improves the construction device.

[0056] Reference Figure 5 and Figure 6 The construction device also includes a first fixing mechanism 9 and a second fixing mechanism 10 , and the first fixing mechanism 9 and the second fixing mechanism 10 are fixed on the frame 4 .

[0057] Reference Figure 5 and Figure 6 The first fixing mechanism 9 includes a fixing sleeve 91 , a first connecting rod 92 , a first abutting plate 93 and a hand wheel 94 .

[0058] Reference Figure 5 and Figure 6 The fixing sleeve 91 is arranged vertically, and the fixing sleeve 91 is fixedly connected to the frame body 41. The first connecting rod 92 is threadedly connected to the fixing sleeve 91, and the first abutting plate 93 is arranged horizontally, and the first abutting plate 93 is fixedly arranged on the side of the first connecting rod 92 close to the ground, and the first abutting plate 93 is fixedly abutted against the ground. The hand wheel 94 is fixedly arranged on the side of the first connecting rod 92 away from the first abutting plate 93, so that the staff can turn the first connecting rod 92. Thus, by utilizing the threaded connection between the first connecting rod 92 and the fixing sleeve 91, the first abutting plate 93 is abutted against the ground, so that the universal wheel 51 of the moving assembly is separated from the ground, thereby fixing the construction device at the installation position, reducing the movement of the construction device; thereby improving the safety of the construction device in the process of hoisting the autoclaved aerated concrete strip 3. In addition, a wear-resistant rubber sheet can be arranged on the side of the first abutting plate 93 close to the ground to increase the friction between the first fixing mechanism 9 and the ground.

[0059] Reference Figure 5 and Figure 6, the second fixing mechanism 10 is fixed on the frame 4; the second fixing mechanism 10 includes a second linear reciprocating drive member 101, a second connecting rod 102 and a second abutment plate 103. The second linear reciprocating drive member 101 is fixed on the frame 4, the driving direction of the second linear reciprocating drive member 101 is vertically arranged, the second connecting rod 102 is vertically arranged, one end of the second connecting rod 102 is fixedly connected to the driving end of the second linear reciprocating drive member 101, and the other end of the second connecting rod 102 is fixedly connected to the second abutment plate 103, and the second abutment plate 103 is used to abut and fix with the ceiling (the second floor 12 in Example 1). By installing the second fixing mechanism 10 on the frame 4, the second linear reciprocating drive member 101 of the second fixing mechanism 10 drives the second connecting rod 102 to move toward the ceiling, so that the second abutment plate 103 in the second fixing mechanism 10 abuts against the ceiling, thereby relatively fixing the construction device between the two floors to reduce the direction of the construction device overturning and improve the construction safety. In addition, a wear-resistant rubber sheet may be provided on the side of the second abutting plate 103 close to the ceiling to increase the friction between the second fixing mechanism 10 and the ceiling.

[0060] Reference Figures 5 to 7 In addition, the construction device also includes a rotating structure 14, which is arranged on the side of the frame 4 close to the lifting gantry 42. The rotating structure 14 is arranged on the side of the frame 4 close to the lifting gantry 42; the rotating structure 14 includes a connecting rod 141, a limiting assembly 142, a flexible member 143 and a rotating roller 144, one end of the connecting rod 141 is fixedly connected to the frame 4, and the other end of the connecting rod 141 is rotatably connected to the limiting assembly 142; the limiting assembly 142 rotates around the end of the rotating rod; the limiting assembly 142 is provided with a limiting groove 1421 for accommodating the autoclaved aerated concrete strip 3, the flexible member 143 is bonded to the groove side wall of the limiting groove 1421, and the flexible member 143 abuts against the autoclaved aerated concrete strip 3. Therefore, by setting a rotating mechanism at the bottom of the lifting gantry 42, when the lifting mechanism 6 lifts the horizontally arranged autoclaved aerated concrete in the vertical direction, the damage to the corners of the autoclaved aerated concrete slats 3 can be reduced, thereby improving the integrity of the steam-pressurized concrete slats and improving the construction quality of the autoclaved aerated concrete wall.

[0061] In this embodiment, the flexible member 143 is a rubber sheet.

[0062] Reference Figure 5 and Figure 6The guide assembly 7 also includes a plurality of guide wheels 72, which are arranged at intervals along the length direction of the guide rod 71. The guide rod 71 is provided with a groove for accommodating the guide wheels 72. The guide wheels 72 are connected to the guide rod 71 in a direction, and the guide wheels 72 are arranged to protrude from the guide rod 71. The surfaces of the plurality of guide wheels 72 are located on the same vertical plane. The guide wheels 72 are used to guide the autoclaved aerated concrete strip 3. By arranging guide rollers on the guide surface of the guide rod 71, when the autoclaved aerated concrete strip 3 moves vertically on the guide surface of the guide assembly 7, the sliding contact between the autoclaved aerated concrete strip 3 and the guide assembly 7 is changed into an over-rolling contact, thereby reducing the friction damage of the autoclaved reinforced concrete strip, and facilitating the workers to hoist the autoclaved aerated concrete strip 3.
