Drawing force and shear force are enhanced by integrating inner-placed anchor bolt structure with substrates to form a whole, which is different from inner separate structure hanging parts in the current market. We present a new safe efficient and cleaning construction technology and method
With the development of building decoration technology, stone material porcelain brick dry hanging technology has been widely applied. But in the current construction process, the construction method of cutting groove and installing hanging parts glue filling has been used by us, so every operator must have certain installation the level. Because the level of constructors is different, it is difficult to control the location and depth of stone machining, fullness condition of glue filling, and the hidden quality problem is easily caused. Through the experimental research in recent years, stone inner-placed anchor bolt dry hanging technology is not only characterized by convenient installation, ensuring construction quality, but also because its convenient factory production and it can save stone resources. The following are the advantages and disadvantages of two stone material dry hanging technologies.
- l??????? Potential dangers of quality in the old type of dry hanging technology
1、The old type of dry hanging technology is opening a notch on every side of the plate. Because of high-speed spinning of the saw blade and the cutting slot is too big, it is easy to break the stone strength, we install a hanging parts in slot. But the force formation of four hanging parts is different, two upside hanging parts are no more than orienting function inside and outside the stone material; two catadrome side hanging parts not only uplift stone material, but also they are subjected to vertical, wind, earthquake loads. Because force is different, if the installation of catadrome side hanging parts is not fastened or stone material is destroyed, two upside hanging parts can't endure the gravity of stone material, which will be separated under deadweight of stone material and cause economic loss and accident
2、As a slot opening downwards of catadrome side hanging parts of stone slab, it is difficult to fill the groove between the stone material and hanging parts with glue. There exist certain crevice, freezing and expansion, which are not avoided. Stone materials under the loading are easy to appear hidden quality problem, such as sidesway, tilt etc..
3、The old type of dry hanging technology? needs power supply on the job site, every installingworker of stone material needs a cutting saw. Therefore, we need abundant implements, cables, which will cause dust pollution, disturbing noise etc.. At the same time, motor machines and cables are liable to cause electric shock and hidden dangers of construction security.
4、Field Installation workers of the old type of dry hanging technology are difficult to fasten hanging parts on the steel frame accurately. Usually, bolts of hanging parts can＇t be fastened on the premoded hole of steel frame. Workers weld hanging parts on the steel frame, because of the effect of the welding thermal stress, deformation of the hanging parts is caused, stone slabs cause shift or tilt, which is a hidden trouble to the bursting of stone material.
5、The majority of workers haven＇t experienced the study and training, stainless steel is used as hanging parts of stone material, and steel framework is all common carbon steel. We need high-level welding technology to weld two different kinds of steels.
6、As the requirement of decorative design for stone material, we need multiple different shape and quality of hanging parts under old method of installation. It is not easy to construct, but also brings troubles for materials supply and warehouse keeping.
7、The old type of dry hanging technology? is affected by construction conditions and operation condition, the quality of hanging parts of stone material can＇t be assured and the filling glue in the slot is poor during winter or sleety climate construction, because bond strength of the glue can＇t be reached under the low temperature conditions.
8、The old type of dry hanging technology? requires that the thicknesses of stone material is more than 20mm, which is disadvantageous to save resource. It is wrong to reinforce the back of stone material with resins when the stone material is thin. If the hanging parts are hung on that location, there will be quality accident, such as crashing or peeling.
- l????????? Advantages of building stone material inner-placed anchor bolt dry hanging new technology
Stone material inner-placed anchor bolt dry hanging technology cuts stone materials into standard boards in factory or on the construction site. Inner-placed white steel anchor bolts are installed in the four angles of the slab stone. On the back of slab stone up and down, four T slots are drilled by? T-Shape special drill, special oval white steel anchor bolts（φ10）are horizontally put into the T slots, then fill T slots with dry hanging glue to complete the requirement of dry hanging technology. The location of inner-placed anchor bolts is accurate which could be calculated. Therefore, whether horizontal or vertical frame skeleton will be installed, setting holes are drilled on the steel skeletons, and then we install stone materials according to the location of special connectors after the installation of the steel skeletons.
- l????????? Advantages of decoration stone material inner-placed anchor bolt dry hanging new technology
1、Inner-placed white steel anchor bolt new technology is in favor of saving stone resources, because T-Shape special drill can drill T slot steadily and the thickness of its head-end slot is no less than 3mm.We don’t need thick stone material, the thinner the stone material and ceramic tile can be hung, which is beneficial for designer to choose different material to design different schemes.
2、Inner-placed anchor bolt new technology use special white steel anchor bolt which is fixed in the stone material,4 anchor bolts are subject to the load of stone material at the same time, installation location of stone material is accurately limited. The experiment shows that stone material will not exfoliated when 3 anchor bolts are out of work and only 1 anchor bolt under load, which provides a security guarantee for preventing the shedding of stone material.
3、Inner-placed anchor bolt new technology is in favor of factory centralized processing, which is suitable for mass production and avoid the effect of external environment and climate on slotting filing glue installation. We don’t need slotting with marble saw on the construction site, operator use only wrench, torch, connector to install stone material. Therefore, it not only ensures stalling quality, but also creates a quiet and safe work environment.
4、Inner-placed anchor bolt technology realizes factory? indoor processing and production, avoids the effect of temperature difference on stone installation, which will not affect installation in the cold winter.
5、Inner-placed anchor bolt technology ensure the location of stone accurately, installation should be? accordance with the premoded hole of steel frame. Successful installation in one time can be ensured with the help of adjustable connector. The installation workers weld hanging parts with electric welding or connect them with screw, which prevent hidden trouble of quality safety in original installation.
6、Inner-placed anchor bolt technology is suitable to install all kinds of porcelain bricks, stone materials, and complex decorative modeling of stone line ,because of its accurate location ,stable performance and you can connect transverse and vertical skeletons. It is more convenient for future maintenance and replacement.
7、Variety and specifications of white steel anchor bolts and connectors of inner-placed anchor bolt technology are unified and easy to use, purchase, and safekeeping. The technology reduces the overall cost of installation by calculation, advances the construction period, saves resources, and creates an environmental construction site. At present, inner-placed white steel anchor bolt technology, connector, etc.. have obtained Chinese patents. In the meanwhile, the experiment result of varied force state of this technology is accorded with the requirements of design.
