Description

TECHNICAL FIELD

[0001] The present application relates to the field of partition wall construction, in particular to a BIM-based ALC partition wall construction method. BACKGROUND

[0002] With the popularity of prefabricated, ALC partition wall in secondary structure is gradually used more and more widely, which can be used as wall material and roof panel, and is a new type of environmentally friendly building material with superior performance. It has the advantages of light weight, high strength, good sound insulation effect, long service life, significant thermal insulation effect, and convenient construction.

[0003] Since the ALC partition wall is a standard prefabricated part, the traditional ALC partition wall construction usually needs to first level the ground before installing the partition wall. However, due to the small area occupied by the partition wall, it is difficult to level the position alone, so the entire ground including the partition wall installation position is usually leveled uniformly, and after solidification, the partition wall is installed, which invisibly prolongs the construction period of the partition wall installation process. And during leveling, almost all processes cannot be carried out, after leveling, other processes are carried out at the same time, which requires coordination of the sequence of each process, and tests the on-site scheduling ability.

[0004] And because the ground area is large, the cement mortar has poor fluidity, even after uniform leveling, there may still be local inclination at the partition wall installation position, and local padding or cement mortar filling of the bottom is still required during the installation of the partition wall, which cannot greatly reduce the labor intensity.

[0089] In the preferred solution, the first notch portion 601 and the second notch portion 602 are offset by a certain distance in the length direction of the partition plate 6.

[0090] The Z-shaped net rack 603 is placed in the Z-shaped mold to pour the Z-shaped precast block 604;

[0091] The Z-shaped precast block 604 is used to connect two adjacent partition plates 6.

[0092] The partition plate 6 is poured through a mold as shown in Figure 3 The size and position of the first notch portion 601 and the second notch portion 602 are fixed, the Z-shaped precast block 604 belongs to a standard size, which can be prefabricated and stored in advance, and does not occupy the construction period.

[0093] The trolley 1 is moved to the partition plate storage place, the turnover frame 3 is turned to be close to horizontal, the clamp device 5 at the front end clamps the side wall of the partition plate 6, and the slide frame 2 drives the clamp device 5 to vertically rise to lift the partition plate 6;

[0094] When the trolley 1 transports the partition plate 6 to the installation site, the turnover frame 3 is turned to be vertical, the height of the slide frame 2 is raised, and then the rotary end of the rotary table device 4 is rotated by ninety degrees to adjust the partition plate 6 to be vertical;

[0095] The trolley 1 is moved to position the partition plate 6 for installation, the plumb device or the inclination sensor is used to feed back the perpendicularity of the partition plate 6, if there is unevenness or inclination on the ground after the partition plate 6 is placed on the ground, the suspended place is padded with a profiled pad 614, and the bottom hollow part is filled with cement mortar;

[0098] One of the left and right sides of the partition plate 6 is aligned with the adjacent partition plate 6, and the front and back sides are flush, at this time, the first notch portion 601 of the partition plate 6 and the second notch portion 602 of the previous partition plate 6 form a Z-shaped notch portion;

[0099] The clamping plate 502 is withdrawn, and the Z-shaped prefabricated block 604 is installed to the Z-shaped gap part, and the Z-shaped prefabricated block 604 is internally provided with a Z-shaped net rack 603, which is formed by steel bars or steel wires and has a three-dimensional net structure and a general Z shape. The step part formed by the first gap part 601 and the second gap part 602 is clamped and connected in a staggered manner, so that the connection between the adjacent partition plates 6 is more stable.

[0100] After the above steps are repeated to install the partition plates 6 into an integral partition wall, the joints between the partition plates 6 and the vertical columns, the joints between the partition plates 6 and the top cross beams and the ground, the joints between the adjacent partition plates 6, and the gaps around the Z-shaped prefabricated block 604 are filled. Due to the continuous pulling force of the Z-shaped prefabricated block 604 on the adjacent partition plates 6, the cracks between the adjacent partition plates 6 are greatly reduced.

[0101] In the preferred embodiment, the mobile frame 102 is further provided, the sliding frame 2 is connected with the mobile frame 102, the tool trolley 1 is provided with a vertical inner groove 106, the mobile frame 102 is provided with a plurality of rollers 107 on both sides, the rollers 107 are installed in the inner groove 106 to roll, the tool trolley 1 is provided with rotatable sprockets 103 at the upper and lower ends, and a chain 105 is further provided, which passes through the sprockets 103 and is connected with the mobile frame 102 at both ends.

The chain 105 is in a closed loop form, and drives the mobile frame 102 to move up and down. The lifting motor 104 is a stepping motor or a servo motor, which accurately controls the turning angle of the turnover frame 3.

[0103] In the preferred embodiment, one end of the turnover frame 3 is hinged to the sliding frame 2, and the other end of the turnover frame 3 is provided with an ear seat 301. The tool trolley 1 is provided with a fixed pulley 110 at the top end, and a winch 7 is provided on the side of the tool trolley 1 away from the clamp device 5.

The ear seat 301 is folded to the sliding frame 2 by winding the winch 7, and the ear seat 301 is turned downward by gravity when the winch 7 is unwound.

[0105] Since the chain 105 is connected in a closed loop, the displacement of the sliding frame 2 is not affected when the winch 7 is working. However, the lifting force of the pull cable 701 actually reduces the load of the sliding frame 2, which is equivalent to a counterweight, and assists the lifting motor 104.

[0112] When the second partition wall plate 6 approaches the first installed partition wall plate 6, the front-rear movement is relatively convenient because the support leg frame 101 is long and narrow, the universal wheel 109 is arranged at the rear end, and the handrail 9 is located at the rear end. However, the left-right transverse movement is prone to cause turning and is not easy to move as a whole. In addition, because the ground is not absolutely level, the perpendicularity of the partition wall plate 6 will also change when the position of the tool trolley 1 changes. In order to reduce this change, the front-rear movement of the tool trolley 1 is mainly adjusted to make the two partition wall plates 6 flush in the front-rear direction. After adjusting the perpendicularity of the partition wall plate 6, the transverse moving frame 303 is adjusted to make the partition wall plate 6 transversely move and stick to the side of the first installed partition wall plate 6, and the perpendicularity of the partition wall plate 6 will not be changed. At this time, the Z-shaped net rack can be installed to connect the adjacent partition wall plates 6 into one body, avoiding displacement of the partition wall plate after the clamp is removed.
