At present, china is in the rapid process of town, the comprehensive well-being is realized by 2020, the town level reaches about 60%, the town population is increased by about 3 hundred million, and the number of town houses is kept to be higher in a longer time. However, the current newly added building is still built in the traditional rough building mode with high energy consumption and high pollution.

The beam column is used as a main structure, is mature in the assembled structure technology, but the research of an assembled wallboard structure system matched with the beam column is relatively lagged. One of the important indexes for checking the industrialization level of the assembled structure is the assembly degree of the wallboard, and the difference of the assembly connection forms of the wallboard and the main body frame has a great influence on the rigidity of the main body structure, and even the unreasonable arrangement can lead to the damage of the main body structure. The existing assembled wallboards are mostly assembled externally hung wallboards, and are mostly used as outer protective members of the structure, rigidity and bearing capacity are not provided for a main body structure, and conversely, the externally hung wallboards have certain mass, so that gravity load of structural stress members is increased, and the design strength and engineering cost of the main body structure are increased.
How to reliably realize the connection problem of the assembled wall body and the upper beam and column of the light steel frame, so that the problem that the wallboard becomes a structural stress member is not solved well, and the problem to be solved in the building system with the assembled structure is urgent to develop, popularize and apply, and is also an important reason that the building system with the assembled structure cannot be popularized in a large scale.

In order to achieve the above purpose, the invention adopts the following technical scheme:
The assembled built-in heat preservation concrete composite wall-light steel frame connecting node comprises outer leaf concrete (1), a built-in heat preservation (2), inner leaf concrete (3), a concrete frame (4), an outer leaf orthogonal steel bar mesh (5), a frame steel bar mesh (6), an inner leaf orthogonal steel bar mesh (7), embedded bolts (8), bolt connecting grooves (9), connecting angle steel (10), light steel frame columns (11) and light steel frame beams (12); the method comprises the steps of arranging an outer leaf orthogonal reinforcement mesh (5) in the middle of an outer leaf concrete (1), arranging a frame reinforcement mesh (6) and embedded bolts (8) at the position of a concrete frame (4), pouring the outer leaf concrete (1), arranging a built-in heat preservation layer (2) on the upper layer of the outer leaf concrete (1), pouring the concrete frame (4) around the built-in heat preservation layer (2), arranging an inner leaf orthogonal reinforcement mesh (7) in the middle of an inner leaf concrete (3), pouring the inner leaf concrete (3), reserving bolt connection grooves (9) at the position of the embedded bolts (8) of a composite wall during pouring, and curing a wallboard to form an assembled built-in heat preservation layer concrete composite wall; and connecting angle steel (10) with reserved bolt holes are welded on the light steel frame columns (11) and the light steel frame beams (12), and when the light steel frame columns are assembled, the embedded bolts (8) on the composite wall penetrate through the bolt holes on the connecting angle steel (10) and are connected with the light steel frames, so that an assembled built-in heat-insulating layer concrete composite wall-light steel frame connecting node is formed.

The casting thickness of the outer page concrete (1) and the inner page concrete (3) is 40-80 mm, the casting width of the concrete frame (4) is not less than 60mm, and the strength grade of the concrete is C30-C60.

The plane of the frame reinforcing steel bar net (6) is perpendicular to the plane of the outer page orthogonal reinforcing steel bar net (5), the vertical reinforcing steel bars of the frame reinforcing steel bar net (6) are encrypted, and the distance is smaller than the distance between the wall plates.
The wall board is characterized in that the periphery of the built-in heat preservation layer (2) is reinforced by the concrete frame and the frame reinforcing steel bar net is encrypted, so that the periphery strength of the built-in heat preservation layer (2) of the wall board is ensured.
The specification of the embedded bolts (8) is not smaller than M14, the required number is calculated according to the required connection strength of the structure, but the number of the connecting bolts on each connecting edge of the composite wall and the light steel frame column (11) is not smaller than 3; and part of the embedded bolts (8) are poured in the concrete frame (4), and the rest screw rods are exposed in the bolt connecting grooves (9) so as to be in bolt connection with the connecting angle steel (10) on the light steel frame column (11) during wallboard assembly.
The bolt connecting grooves (9) are rectangular grooves, the bottom surface is not lower than the upper surface of the built-in heat insulation layer (2), and the side length of each rectangular surface of each groove is not less than 50mm; the bolt connecting grooves (9) are arranged at corresponding positions of the embedded bolts (8) along four sides of the composite wall, so that the tail ends of the screw rods of the embedded bolts (8) can be exposed out of the foaming concrete for connecting the wall with the nodes of the frame, and the plane of the wallboard is not protruded; after the wall body is assembled, the bolt connection groove (9) is filled with building filling materials, so that the plane of the wall board is smooth. The building filler material comprises grouting material, cement mortar or fine stone concrete.
The thickness of the connecting angle steel (10) is not smaller than 4mm, and the size of one end connected with the wallboard is smaller than the size of the bottom surface of the bolt connecting groove (9), so that the collision of assembly nodes is prevented; the connecting angle steel (10) is provided with bolt holes corresponding to the apertures of the embedded bolts (8), and is welded on the light steel frame columns (11) and the light steel frame beams (12) before the composite wall is assembled, and the embedded bolts of the composite wall are penetrated and connected during the assembly, so that node connection is completed.

Compared with the prior art, the assembled concrete composite wall with the built-in heat preservation layer and the light steel frame connecting node have the following advantages:
(1) The wallboard participates in structural stress, improves the anti-seismic performance of the structure. The existing assembly type building generally adopts an externally hung wallboard which is only used as a peripheral protection member of the structure, does not provide rigidity and bearing capacity for a main body structure, and on the contrary, has a certain mass, and increases the gravity load of a structural stress member, thereby increasing the design strength and the engineering cost of the main body structure. The built-in heat insulation layer and the inner page concrete of the wallboard are embedded into the frame, and mutually transmit load with the beam column of the frame, so that the wallboard can be used as a stress member to participate in stress of a main body structure, provide rigidity and bearing capacity for the main body structure, improve the shock resistance of the structure and reduce the design strength and cost of the beam column member.
(2) Strong node construction provides a secure and reliable fabricated connection. The built-in heat preservation is reinforced by the surrounding concrete frame and the frame reinforcing steel mesh is encrypted, so that the surrounding strength of the wall plate is guaranteed, the strength of the wall body-frame connecting node is further guaranteed, and the wall plate is prevented from being cracked in advance to influence the stress performance of the wall body when load is transferred between the wall plate and the frame column. The connecting bolts are pre-embedded in the concrete frames around the wallboard and are firmly connected with the wallboard; the connecting angle steel is welded on the light steel frame column and the light steel frame beam, and the connecting piece is reliably connected with the frame; finally, the wallboard and the light steel frame column are tightly bolted through the connecting bolts and the connecting angle steel, so that the assembled wallboard and the main body frame are firmly assembled.
(3) Reduce the corrosion of frame beam column steel and improve the fireproof performance of the structure. The steel frame beam column is wrapped outside the outer page concrete, so that the steel frame beam column is isolated from the outside, steel corrosion is reduced, meanwhile, the concrete has a good fireproof effect, and the disadvantage of poor fireproof capacity of the steel frame structure can be overcome.
(4) The integrity is good, and the structure keeps warm and integrates. The inner and outer page concrete of the wallboard forms a foaming concrete shell with higher strength for the wallboard together with the foaming concrete frame, so that the weakening of the wallboard strength by the built-in heat preservation layer in the middle part is relieved, and the component strength is improved. The built-in heat preservation layer is arranged in the middle of the concrete structural slab, so that inflammable heat preservation materials are isolated from the outside, and the heat preservation and fireproof effects are good.
(5) The wallboard is prefabricated in large-scale modularized production in a factory, is easy to manufacture, and is easy to realize high-efficiency industrialized manufacture on a production line. Meanwhile, the large modularized wallboard is convenient for assembly type installation on a construction site, has few and firm installation nodes, is simple to construct, remarkably reduces the operation intensity of workers, reduces the work amount of engineering, effectively shortens the construction time on the construction site, and is suitable for being widely popularized and applied in actual engineering.
