Description

Technical Field

[0001] The invention relates to the technical field of prefabricated parts, in particular to an assembled prefabricated reinforced concrete prefabricated part. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregates (also called aggregates), water, and admixtures and additives added when necessary in a certain proportion, which are uniformly mixed, compacted and hardened. Concrete has the characteristics of abundant raw materials, low price and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability and wide range of strength grades. These characteristics make it widely used. It is not only used in various civil engineering projects, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material. Prefabricated parts are workpieces that are cast and formed with concrete before construction.

[0003] Compared with traditional cast-in-place reinforced concrete and masonry buildings, prefabricated buildings are built in factories to produce building components including beams, slabs, columns and exterior walls, which are then transported to the site for installation and construction after maintenance and acceptance. Prefabricated buildings are divided into prefabricated steel structures and prefabricated reinforced concrete based on building materials. They mainly refer to the production of some or all components in a component prefabrication factory, which are then transported to the construction site by appropriate transportation methods, and assembled using reliable installation methods and installation machinery. They have many advantages such as fast installation speed, water saving, land saving, noise reduction, and material saving.

[0004] According to the search, Chinese patent literature, announcement number: CN113152778A, discloses an assembled prefabricated reinforced concrete prefabricated part, including a fixing plate, a connecting device, a side panel assembly, an outer panel and a window opening device. The present invention can solve the following problems existing in assembled prefabricated reinforced concrete prefabricated parts: a. At present, most of the traditional assembled prefabricated walls have a relatively simple structure, which is only simply assembled and does not have the effect of sound insulation and heat preservation. At the same time, prefabricated walls of different thicknesses required for different environmental places often need to be designed separately in order to be suitable for specific places, resulting in increased R&D costs and limited utilization; b. Most of the prefabricated walls on the market currently do not have slots designed for installing windows, and it is difficult to open slots for installing windows in such prefabricated walls in actual use, which may damage the wall structure. At the same time, the windows installed in different places are of different sizes and difficult to adjust.

[0005] The Chinese patent document, publication number: CN110055976A, discloses a reinforced concrete prefabricated part; comprising a plate body, in which a splicing unit, an anti-seepage unit and an anti-corrosion unit are arranged; the plate body is arranged in an inverted L shape; a group of splicing units are arranged on the side of the plate body, and the splicing units are used for splicing adjacent plate bodies; an anti-seepage unit is arranged on one side of the splicing unit located in the plate body, and the anti-seepage unit is used to prevent seawater from penetrating into the plate body; an anti-corrosion unit is arranged on the side of the anti-seepage unit away from the splicing unit, and the anti-corrosion unit is used to prevent seawater from corroding steel bars in reinforced concrete; the splicing unit, the anti-seepage unit and the anti-corrosion unit cooperate with each other to prevent seawater from passing through the plate body into the foundation pit, and at the same time prevent seawater from corroding concrete and steel bars, thereby ensuring the normal operation of the plate body.

[0006] However, the above-mentioned precast concrete parts and most precast concrete parts on the market still have the following problems: the precast parts usually need to be hoisted by a crane, so steel bar hooks are usually embedded in the precast parts to facilitate crane alignment for hoisting. After the installation is completed, the steel bar hooks need to be cut off, which is complicated to operate, inconvenient to use, and causes waste. Summary of the invention

During the movement, the block squeezes the limiting block, and the limiting block moves after being squeezed and causes the limiting spring to contract. When the block moves to one side of the limiting block, the limiting spring drives the limiting block to reset, thereby realizing the engagement of the block. This structure can realize rapid installation and alignment between the two concrete slabs.

When installing the prefabricated panels, align one side of the block of the two concrete panels with one side of the fixing seat, then move one of the concrete panels to the other side of the concrete panel, and slide the block into the slot of the fixing seat. During the movement, the block squeezes the limit block, which moves after being squeezed and contracts the limit spring. When the block moves to one side of the limit block, the limit spring drives the limit block to reset, thereby achieving the engagement of the block. This structure can achieve rapid installation and alignment between the two concrete panels, avoiding offset and dislocation during installation, which affects subsequent operation and use.

[0020] 3.

The carrier for the micro-bubble glass is a special resin with high performance, which is the sum of polymers and copolymers. It can be used in combination with flexible waterproof coatings and rigid waterproof coatings, and can also be directly constructed on various base layers to independently exert the good performance of waterproof coatings and heat-insulating coatings. The fire-retardant coating 9 is a steel structure fire-retardant coating, which is composed of a binder (such as silicate cement, magnesium oxychloride or inorganic high-temperature adhesive), aggregate (expanded vermiculite, expanded perlite, aluminum silicate fiber, mineral wool, rock wool, etc.), chemical additives (modifiers, hardeners, waterproofing agents, etc.), and water.
