In this observation, the characteristics and advantages of the assembled integrated wallboard were explained in detail, the mechanical installation method was displayed on site, and an observation seminar was held.

In traditional wall masonry or wall panel installation, cement-based mortar is usually used as cementitious material at the junction of ground wall.

The wallboard adopts multi-channel fixation and mutual coercion.

The upper and lower wall panels are fixed with corrugated sheets at multiple points and both sides.

Observe and summarize the seminar and explain the characteristics and advantages of materials on site # cast integrated wallboard # cast integrated wallboard is made of existing autoclaved aerated concrete blocks bonded by adhesive and painted on the surface to form a finishing layer.

It can enter the site quickly after receiving the construction task.

When cement-based mortar is used in construction, because it cannot bear the heavy pressure of wall materials, the water is removed, resulting in the loss of strength of mortar or the wall sinking during construction, resulting in wall cracking.

There are no problems such as VOC (volatile organic compounds), which can effectively reduce the possibility of generating thermal bridge and avoid a large amount of dust generated in the process of on-site masonry by traditional technology, It meets the energy conservation and emission reduction needs of the construction field under the current “double carbon” goal.

The area of 1200mmx1500mm (conventional) single wallboard is consistent with the traditional wallboard, the thickness is according to the design needs, the whole wall height is customized according to the design requirements, and the blocks form the wallboard through gluing, Taking advantage of the stability of small-sized blocks can effectively avoid the variability defects of long plates, which are not easy to deform, the wall plates are stable, convenient for transportation and easy to install, and can also reduce the dust from construction site, so as to realize the industrialization of wall construction and the digitization of engineering assembly, so as to ensure the digitization of wall design.

Each wallboard is fixed with more than two casing connectors.

When an ALC wall panel has internal stress release or thermal expansion and cold contraction, the stress will be dispersed and transmitted through multiple fixed channels to release the stress to the whole wall and resolve the release of stress at the corresponding point, so as to solve the wall cracking and ensure the stability of the wall.

The wallboard of the wall forms an upper and lower inclined angle for fixation, the left and right wallboards are fixed with corrugated sheets, and the leveling grid eliminates the risk of wallboard sinking.

The mechanized construction of precast wall meets the development trend of industrialization and the demand of carbon emission reduction, and conforms to the development direction of intelligent construction at the same time.

Its overall structure is relatively stable, which is compared with the common problems of cracking, hollowing and low installation efficiency in the traditional wallboard installation process, The precast integrated wallboard has the following advantages: 01.

Steel Chamfer

The precast integrated wallboard is uniformly produced in the workshop and has achieved a 28 day maintenance cycle.

On February 24, the relevant departments of Fuzhou Urban Rural Construction Group under Fuzhou Urban Investment Group invited the management personnel of Fuzhou urban rural construction development group to observe the application practice of the new material assembled integrated wallboard used in the bid section II of the new library of Minjiang University, a project under construction by Fuzhou urban rural construction group.

The application of grid can effectively solve the water retaining function of mortar at the junction of ground wall, effectively bear the heavy pressure of wall materials in construction, and will not cause the cracking phenomenon caused by wall subsidence and the loss of mortar strength caused by mortar dewatering.

05 precast integrated wallboard adopts mechanical installation and construction on site, man-machine cooperation liberates labor force and improves construction efficiency.

The precast integrated wallboard adopts the special adhesive for masonry as the binder of autoclaved aerated concrete to replace the original mortar, cement and other original building materials.
