Description

Integral box-type structure of steel space grid assembly for small high-rise energy-saving residential buildings

technical field

The patent of the present invention relates to an integral box-type structure, in particular to a steel-assembled integral space grid box-type structure for cast-in-place industrial gypsum exterior walls of small high-rise energy-saving residential buildings.

Background technique

With the development of my country's economic construction, my country's steel output has grown from tens of millions of tons to more than 500 million tons. The rapid increase in steel output has promoted the development of steel structure houses. Some large and medium-sized cities across the country have been developed in large areas. , and some are being developed, but compared with small high-rise residential buildings with reinforced concrete structure system, the development of steel structure residential buildings is only rare. Reinforced concrete frame structure residential buildings are tall. One of the key issues to reduce costs is the amount of steel used. From the analysis of the small high-rise residential buildings ( H ≥ 50m) that have been developed now, the structural system is still the traditional steel frame structure of small column net or large column net and cast-in-place concrete shear force. The traditional structure and construction method of the steel frame of the wall (staircase and elevator room), steel secondary beams, and profiled steel plate composite floor. The steel consumption of a 15-story steel structure residence is (120kg/m ² ~150kg/m ² ) Between, assuming that there are four households in one elevator, the building area of each household is 125m ² , 15 floors (excluding the basement floor), the building area is 7500m ² , the total steel consumption is 900T~1125T, and the unit price of the steel structure (manufacturing, transportation, installation, etc.) at 12,000 yuan/ton, RMB 10.8 million to 13.5 million yuan is required, that is, the cost price of steel structure construction (1440 yuan/m ² to 1800 yuan/m ² ) is higher than the cost price of ordinary reinforced concrete frames ( 50%~80%), the sales price of natural steel structure residences is much higher than that of conventional residential buildings. At the same time, conventional steel frame residential buildings cannot freely divide the rooms of each household, and must be "where there are walls, there must be beams". In addition, there must be welding procedures in the construction of steel structures, and fire prevention measures are very important. The steel frame columns and beams are large and heavy, and the construction is difficult, which leads to relatively lagging construction progress and construction civilization.

How to overcome the shortcomings of conventional small high-rise steel frame structure residential buildings, that is, the above-mentioned high cost, large and heavy components, difficulty in transportation and installation, and the need to avoid construction site welding, ensure the quality and safety of the structural system, and avoid the need for steel structure protection The new system of rust and fire prevention treatment is the focus of the building structure engineering field.

Contents of the invention

The present invention mainly solves the deficiencies in the prior art, and provides a kind of unit member formed by welding and connecting in the factory workshop, which is transported to the construction site and connected by high-strength bolts to form a double-layer hollow slab floor and a single-layer Each side of the outer wall and the wall frame of each household, the vertical and horizontal grids form a grid plate, and each household is composed of a horizontal and vertical grid plate to form a grid plate box-type space structure, so that the inside of the structure is evenly distributed, and The internal force value is greatly reduced, so that the section of the component is greatly reduced, thereby reducing the amount of steel used and the cost of the project. The section steel space grid assembly integral box structure of small high-rise energy-saving residential buildings.

The above-mentioned technical problems of the present invention are mainly solved by the following technical solutions:

A steel space grid assembled integral box-type structure for a small high-rise energy-saving residential building, including a wall frame grid, and the wall frame grid is assembled by A component unit, B component unit, C component unit and D component unit The A component unit, the B component unit, the C component unit and the D component unit are respectively assembled from vertical components and transverse components, and the end connections of the vertical components and the horizontal components are respectively High-strength bolts join the holes, and the two ends of the wall frame grid are poured with gypsum layers respectively.

The wall frame grid is composed of factory processing units of the wall frame. There are two component units A and B at the straight part of the wall, and C and D component units at the right corner. These units are processed and welded in the factory, such as A at the window hole The vertical columns and transverse beams of the component units are all H-shaped steel, welded into a double cross-shaped frame, and the components are all opened with high-strength bolt holes. After being transported to the construction site, these units are connected from the first floor layer by layer with high-strength bolts to form a whole. . When each layer of wall frame is ready to be installed, formwork is erected on both sides of the steel grid wall frame, and industrial gypsum grout is poured layer by layer on site, and the surface layer of the wall frame steel grid member is wrapped at least 25mm thick to prevent rust and fire. The steel structure wall and floor of the entire small high-rise residential building are made of steel space grids to form a box, and then industrial gypsum exterior walls and household walls are poured, and then prefabricated industrial gypsum blocks are used on the floor slabs of each large bay. Divide the living room, that is to form a small high-rise large bay to flexibly divide the living room industrial gypsum energy-saving building.

A component unit, B component unit, C component unit and D component unit form a number of grids, and the number of vertical grids is greater than or equal to 3 grids.

As a preference, the A component unit is continuously distributed, and the two ends of the A component unit are D component units assembled therewith, above the A component unit is the B component unit, and the B component unit is continuous Distribution, the two ends of the B component unit are assembled with the C component unit, the C component unit is located above the D component unit, and the A component unit is provided with a portal.

Preferably, the A component unit, the B component unit, the C component unit and the D component unit are strongly connected to each other by high-strength bolts, etc., and the thickness of the gypsum layer is at least 25mm.

The present invention is a small high-rise energy-saving residential building with a steel space grid assembly integral box structure, which has a simple structure, low cost, simple and safe installation, and a reasonable stress system.
