Description

Technical Field

[0001] This invention relates to the field of wall-mounted thermal insulation and waterproofing technology, specifically to a wall-mounted structural thermal insulation and waterproofing structure. Background Technology

[0002] Compared to the attached lining structure, the off-wall lining structure adds a sealed air layer and drainage ditch. It is generally suitable for situations where the surrounding rock has good integrity, few joints and fissures, and the rock is hard, stable or basically stable. It is widely used in tunnel construction.

[0003] In actual use, existing detached lining structures are prone to heat exchange between the inside and outside of the structure due to environmental factors. This leads to unstable internal heat and difficulty in ensuring the internal insulation effect, which in turn makes the detached lining structure susceptible to damage. Furthermore, groundwater intrusion can also damage the detached lining structure. Therefore, a detached structure with thermal insulation and waterproofing is designed to meet actual construction needs. Summary of the Invention

[0004] The purpose of this invention is to provide a detached thermal insulation and waterproof structure to solve the problem mentioned in the background art that internal heat and water intrusion can easily lead to damage to the detached lining structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wall-mounted thermal insulation and waterproof structure, comprising a concrete wall, wherein the inner side of the concrete wall is coated with a 1mm thick crystalline waterproof coating for waterproof protection of the left side of the concrete wall, and the outer side of the concrete wall is coated with a 20mm thick mortar leveling layer to ensure the flatness of the right side surface of the concrete wall.

[0006] Also includes:

[0007] A high-viscosity, anti-slip water-based rubber asphalt waterproof coating is uniformly applied to the right side of the mortar leveling layer, with a thickness of 1.5mm. A 1.5mm thick self-adhesive polymer waterproof membrane is bonded and fixed to the right side of the high-viscosity, anti-slip water-based rubber asphalt waterproof coating. A water-repellent rock wool board is installed to the right side of the self-adhesive polymer waterproof membrane. A geogrid is laid to the right side of the water-repellent rock wool board. A drainage ditch is installed below the geogrid and is located on the right side of the concrete wall. Hooked expansion bolts are fixed to the drainage ditch, and a connecting frame is installed between the drainage ditch and the geogrid.

[0008] Preferably, the self-adhesive polymer waterproof membrane is coated with an adhesive layer, and the self-adhesive polymer waterproof membrane is bonded and fixed to the water-repellent rock wool board body through the adhesive layer. When fixing the water-repellent rock wool board body, the adhesive layer can ensure the stability of the fixation between the self-adhesive polymer waterproof membrane and the water-repellent rock wool board body.

[0009] Preferably, the gaps between the spliced ​​hydrophobic rock wool boards are sealed with sealing tape, and the sealing tape is made of butyl tape. When multiple sets of hydrophobic rock wool boards are spliced ​​and assembled, the sealing effect of the sealing tape can ensure the sealing between the spliced ​​gaps of the two sets of hydrophobic rock wool boards and prevent water seepage.

[0010] Preferably, the hydrophobic rock wool board body is made of single-sided aluminum foil hydrophobic rock wool board with a density of 100 kg / m3, a thermal conductivity of 0.045 (W / m·k), a heat storage coefficient of 0.77 (W / m·k), a water absorption rate of no more than 1%, a water repellency rate of no less than 98%, a compressive strength of no less than 40 kPa, a dimensional stability of no more than 1%, a tensile strength perpendicular to the surface of no less than 10 kPa, and a fire performance rating of Class A. Through the action of the hydrophobic rock wool board body, the insulation effect of the wall-mounted structure can be achieved, effectively preventing heat diffusion. Moreover, the hydrophobic rock wool board body has good physical properties, is not easily damaged, and is non-combustible, thus achieving a fireproof effect.

[0011] Preferably, the geogrid is fixed at both ends with a folded-over design. The steel pipe has a wall thickness of 2.8mm and an S-shaped hook with a diameter of 8mm is fixed at the lower end. The steel pipe facilitates the winding and unfolding of the geogrid, thus making the laying of the geogrid easier.

[0012] Preferably, the steel pipes are tied together and fixed by straps, and the straps are evenly distributed on the steel pipes. When splicing two sets of geogrids, the steel pipes on the two sets of geogrids are bound together by the straps, which can ensure the stability of the geogrid splicing.

[0013] Preferably, the hooked expansion bolts are evenly distributed in the drainage ditch, and the distance between two adjacent sets of hooked expansion bolts is 1000mm. By limiting the distance between the hooked expansion bolts, the assembly of the geogrid can be facilitated.

[0014] Preferably, the connecting frame is connected to a threaded rod by a thread, and the threaded rods are symmetrically distributed about the center line of the connecting frame. The threaded connection between the threaded rod and the connecting frame can provide a basic force for the fastening of the geogrid.

[0015] Preferably, the threaded rod is further provided with a first hook and a movable ring;

[0016] The first hook is fixed on the threaded rod, and the first hook on the upper side of the connecting frame is engaged with the S-shaped hook, and the first hook on the lower side of the connecting frame is engaged with the expansion bolt with hook.

[0017] The movable ring, with a bearing connected to the threaded rod, is slidably connected to the connecting frame. It can be secured to the geogrid by being hooked to the S-shaped hook and the expansion bolt with hook by the upper and lower sets of first hooks respectively.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the off-wall thermal insulation and waterproof structure, by adding water-based rock wool board, self-adhesive polymer waterproof membrane and high-adhesion anti-slip water-based rubber asphalt waterproof coating to the existing off-wall structure lining, effectively improves the waterproof and thermal insulation performance of the existing off-wall structure, is more conducive to building energy consumption control, solves the problem of thermal insulation and waterproof construction of the off-wall structure lining at low cost, and is suitable for widespread application.

[0027] When using a wall-mounted thermal insulation and waterproofing structure, such as Figure 1 and Figure 2As shown, firstly, a 1mm thick layer of crystalline waterproof coating 2 is uniformly applied to the left (outer) side of concrete wall 1 using an existing coating device, thus achieving waterproofing on the left side of concrete wall 1. Then, waterproofing and insulation are applied to the right (inner) side of concrete wall 1. A 20mm thick mortar leveling layer 3 is uniformly applied to the right side of concrete wall 1 using an existing coating device, ensuring the smoothness of the mortar leveling layer 3 surface. After the mortar leveling layer 3 dries, a 1.5mm thick layer of high-adhesion, anti-slip, water-resistant rubber asphalt waterproof coating 4 is uniformly applied to the right side of the mortar leveling layer 3 using an existing coating device, thus achieving one layer of waterproofing. Finally, a layer of high-adhesion, anti-slip, water-resistant rubber asphalt waterproof coating 4 is applied to the right side of the mortar leveling layer 3.
