The height of the railing mainly depends on the object and location of use, generally 9 millimeters high; The staircase railings of kindergartens and primary schools can also be built in the form of double handrails, which can be used by adults and children respectively; Additional increases may be made at the discretion of high-risk areas. Stone fence is a major representative of stone fence posts. Blue stone is a kind of green gray marble with a solid texture and special weathering resistance. It is widely used in large-scale stone memorial archway, stone tablet and other architectural stone carving projects. Stone barriers play a role in separating and guiding in use, making the boundaries of the divided area clear and distinct. The designed railings are very decorative. The former consists of columns, handrails, and crossbars, with the handrails supported on the columns; The latter has a continuous handrail consisting of handrails, railing posts, and a base.

Construction preparation
1. Quality management at the construction site should have corresponding construction technical standards, a sound quality management system, construction quality control, and quality inspection systems. Before grouting, there should be a construction organization design or construction technical plan, which should be reviewed and approved.
Before grouting construction, mixing equipment, grouting devices, templates, and maintenance items should be prepared.
3. In addition to complying with the relevant provisions of the current national standard "Code for Acceptance of Construction Quality of Concrete Structures" GB 50204, formwork support should also comply with the following regulations:
① During secondary grouting, the horizontal distance between the formwork and the equipment base should be controlled at around 100mm; The top elevation of the template should not be lower than 50mm above the surface of the equipment base.
② When renovating and reinforcing concrete structures, sufficient grouting holes and exhaust holes should be left in the formwork support. The diameter of the grouting holes should not be less than 50mm, and the spacing should not exceed 1000mm. The grouting holes and exhaust holes should be 50mm higher than the high point of the holes.

This method has a certain proportion of application in cold northern regions. This type of wall has certain insulation performance, but its disadvantages are also very obvious. External wall insulation structure. With the rapid development of external insulation technology in recent years and the continuous improvement of national energy-saving standards, the application of external wall insulation has been expanding and has been recognized by regulatory authorities, experts, developers, and residents. Due to the fact that the external insulation system is placed on the outer side of the exterior wall and directly bears the effects of natural thermal stress, water, wind, fire, and earthquakes, higher requirements have been put forward for the external wall insulation system. Due to the obvious advantages of external insulation in protecting the main structure, extending the life of buildings, improving wall moisture conditions, and increasing building area, the application of external insulation will continue to expand and become mainstream.

construction method
▲ Mixing
When mixing cement-based grouting materials, water should be added according to the required amount of water for the product.
2. Cement based grouting materials should be mechanically mixed. When mixing, it is advisable to first add 2/3 of the water and mix for about 3 minutes, then add the remaining amount of water and mix until uniform. If there are specific mixing requirements for AGM-340 products, they should be mixed according to their requirements.
3. The mixing site should be close to the grouting site.
▲ Anchor grouting of foundation bolts
1. The construction process of anchoring anchor bolts should meet the following requirements: ① Cleaning hole 1 ② Cleaning accumulated water in the hole 1 ③ Removing oil stains and rust on the surface of the bolt 1 ④ Inserting bolt adjustment and fixing 1 ⑤ Mixing AGM-340 grouting material 1 ⑥ Building 1 ⑦ Maintenance 1 ⑧ Installing equipment.
When drilling anchor bolts, the horizontal deviation of the bolt holes shall not exceed 5mm, and the vertical deviation shall not exceed 5 °. The wall of the bolt hole should be rough, and the hole should be cleaned thoroughly without any floating dust, oil stains or other impurities. Before grouting, soak it in water for 8-12 hours to remove any accumulated water in the hole. When the ambient temperature is below 5 ° C, measures should be taken to preheat and maintain the temperature above 100 ° C.
Before grouting, the oil stains and rust on the surface of the anchor bolts should be removed.
When pouring the mixed cement-based grouting material into the bolt holes, the position of the bolts can be adjusted as needed. Vibration is strictly prohibited during the grouting process, and bolts cannot be adjusted again after grouting is completed.
5. The upper surface of the grouting layer inside the hole should be about 50mm lower than the surface of the foundation concrete.

And it can replace redispersible latex powder, polyol 17 series adhesive, modified starch adhesive, modified cellulose, cooked rubber powder and various polymer adhesives, etc. It is used in cement mortar, dry mixed mortar, exterior wall insulation mortar, bonding tiles, gypsum products, waterproof materials, etc. It has strong water retention, increased viscosity, workability, and firmness, and its comprehensive performance is superior to related products. Instructions for using instant glue powder: Add the specified amount of glue water powder while stirring in a certain amount of water, stir for 1-5 minutes until all the glue powder is dissolved, and let it stand for 15 minutes before use. Add 1kg of instant rubber powder while stirring in 5kg-8kg of water, stir for 1-5 minutes, and let it stand for 15 minutes.
▲ Secondary grouting
The appropriate grouting method should be selected for secondary grouting according to the actual situation of the project. The process flow should meet the following requirements: ① Cleaning the equipment foundation ② Soaking in water 24 hours in advance ③ Clearing accumulated water before grouting ④ Preparation of construction equipment ⑤ Mixing AGM-340 grouting material ⑥ Secondary grouting ⑦ Curing.
Before grouting, the equipment base plate and concrete foundation surface in contact with the grouting material should be cleaned thoroughly, and there should be no loose crushed stones, floating slurry, oil stains, wax, etc. 24 hours before grouting, the surface of the foundation concrete should be fully wetted, and the accumulated water should be removed 1 hour before grouting.
During secondary grouting, grouting should be carried out from one side until it overflows from the other side, and grouting should not be carried out simultaneously from opposite sides. After grouting begins, it must be carried out continuously and the grouting time should be shortened as much as possible.
When the track foundation or grouting distance is long, it can be constructed in sections according to the actual engineering situation.
5. Vibration is strictly prohibited during the grouting process. If necessary, a grouting booster should be used (pushing the grouting material along the bottom of the grout flow direction, and it is strictly prohibited to push it from the middle or upper part of the grouting layer).
After the equipment foundation grouting is completed, it is advisable to cut a 45 ° angle outward along the edge of the bottom plate 3-6 hours after grouting.

Install in a top-down sequence, first installing the vertical keel and then installing the horizontal keel. Installation of fireproof layer for curtain wall: Galvanized steel plates are fixed on the horizontal material between the curtain wall and each floor slab according to the design requirements. The galvanized steel plates are filled with fireproof rock wool, and it is required to be filled tightly without gaps. Installation of curtain wall insulation layer: The installation of mineral wool felt must be completed before the installation of curtain wall panels, but it should be carried out successively with the installation of panels. According to the specifications of the mineral wool felt, the position of the adhesive nails should be arranged first. Generally, there are 9 adhesive nails per piece of mineral wool felt. The adhesive nails should be pasted on the outer surface of the wall, and the surface of the adhesive nail distribution points must be cleaned thoroughly, without moisture, oil stains, dust, etc., and ensure safety and reliability.
