Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of the construction technology of the basement external wall of infrastructure and construction projects, and particularly relates to the fields of waterproof and thermal insulation of the external wall of the subway structure, the side wall of the basement and the external wall of the basement. Background Technique
[0002] External wall external thermal insulation is to set the thermal insulation layer on the outer surface of the building external wall, mainly including a decorative layer and a thermal insulation layer. The thermal insulation layer is an efficient lightweight thermal insulation material with a small thermal conductivity, and it needs to meet the thermal insulation and energy-saving requirements of walls in different regions, and has a low moisture absorption rate and strong adhesion. At present, polystyrene board is the most commonly used external thermal insulation material, including expanded polystyrene board (EPS) and extruded polystyrene board (XPS). External wall external thermal insulation is not only commonly used in new buildings, but also very beneficial to the energy-saving renovation of old buildings, and does not affect the indoor living environment. However, internal wall thermal insulation is prone to some weak parts, such as the joints between the internal and external walls, the corners of the external wall, the keel structure, etc. Therefore, the thermal insulation effect is poor, and it occupies the indoor usable area, which is not conducive to the development of indoor decoration activities. However, it has obvious advantages in terms of safe construction, building fire protection, etc., so it has also been applied to a certain extent.
[0003] In China's buildings, the phenomena of roof leakage, underground project leakage, leakage of external walls and road and bridge projects are still very common, and the disputes over cases related to the quality of construction projects caused by this are increasing. With the increasing awareness of the importance of waterproofing, the requirements for building waterproof materials are getting higher and higher. Building waterproof materials refer to materials that prevent rainwater, groundwater, industrial and civil water supply and drainage, corrosive liquids, and moisture and steam in the air from invading buildings. Commonly used waterproof coiled materials can generally be divided into asphalt waterproof coiled materials, polymer modified asphalt waterproof coiled materials, and synthetic polymer waterproof asphalt coiled materials according to the change of material components. Waterproof coatings refer to substances that are in a viscous liquid state at normal temperature, are coated on the surface of the substrate, and form a continuous film with a certain elasticity through the volatilization of solvents or water or the chemical reaction between components, so as to isolate the surface of the substrate from water and play a role in waterproofing and moisture-proofing.
[0004] However, the thermal insulation layer and waterproof layer of many construction projects are often damaged during the construction process, especially the thermal insulation and waterproof layers of the basement external wall. Due to non-standard operations during the construction process, it may lead to the peeling off and damage of the thermal insulation and waterproof layers. Content of the Utility Model
[0005] The purpose of the utility model is to provide a reinforcement structure for the waterproof and thermal insulation layer of the basement external wall, and solve the problems that the thermal insulation layer and waterproof layer are easily damaged during the construction process, resulting in peeling off and damage.

[0010] The strengthening framework is formed by welding angle steels in a grid pattern, with a specification of L50 angle steel 2000*2000 mm.
[0011] The longitudinal section of the angle steel diagonal bracing frame is a right triangle, formed by welding angle steels, and includes a right triangle outer frame and angle steel tie rods connected and welded end to end in a Z shape inside the right triangle outer frame; two steel plate bases are welded at intervals on the bottom rod of the right triangle outer frame, and the steel plate bases are fixed to the retaining pile or the backfilled concrete foundation by expansion bolts.
[0012] A further preferred technical solution: When the inside of the retaining pile is backfilled with soil, a backfilled concrete foundation with a specification of 800*800*800 mm is added under the angle steel diagonal bracing frame.

[0019] Compared with the prior art, the utility model has the following characteristics and beneficial effects:
[0020] During the construction process, due to reasons such as rainwater scouring, wind load, dynamic load, and human damage, the insulation boards and waterproof coiled materials often fall off and are damaged. The utility model uses a continuously arranged strengthening skeleton and an angle steel bracing frame to reinforce the thermal insulation and waterproof layer, enabling the insulation boards and waterproof coiled materials to be not easily detached during the construction process, avoiding damage during construction, achieving a supporting and protecting effect, minimizing the loss of thermal insulation and waterproof materials, reducing the later repair and replacement work, ensuring the integrity of the thermal insulation and waterproof materials, and guaranteeing the quality of the thermal insulation and waterproof sub-projects.
