As shown in fig. 1-2, a wall structure connecting ring beam for preventing cold and hot bridges between upper and lower floors, which is to prevent the adverse effects of uneven settlement of the foundation or large vibration load on the building, should be provided with a reinforced concrete ring beam or a reinforced brick ring beam in the wall to enhance the overall rigidity of the masonry building. The number of the ring beams is determined according to the structure and the construction condition of a house, and for single-layer houses with large spaces, such as workshops, warehouses and dining halls, when the wall thickness is equal to or less than one brick and the elevation of the cornice is 5-8 meters, one ring beam is required to be arranged, and when the elevation of the cornice is more than 8 meters, one ring beam is preferably additionally arranged; for a single-layer industrial factory building with an electric bridge crane or larger vibration equipment, besides arranging a reinforced concrete ring beam at an eave or a window top, a ring beam is additionally arranged at a position at the elevation of a crane beam or in a proper position of a wall; for multi-storey civil houses, such as dormitories, office buildings and the like, when the wall thickness is equal to or less than one brick and the number of stories is not less than three, one ring beam is preferably arranged, when the wall thickness exceeds four stories, the ring beams can be properly added, the ring beams are continuously arranged on the same level of the wall, form a closed ring as far as possible and are properly connected with transverse wall columns, and when the ring beams are cut off for door and window openings and cannot pass through, an additional ring beam is arranged in the brickwork at the upper part of the opening. The width of the reinforced concrete ring beam is generally the same as the wall thickness, when the wall thickness is larger than one brick, the ring beam is not suitable to be smaller than 2/3 wall thickness, and the height of the reinforced concrete ring beam is equal to the multiple of the thickness of each brick of the masonry. The reinforced concrete ring is generally cast-in-place, but a prefabricated assembly cast-in-place joint mode can also be adopted.

The connecting ring beam of the wall structures of the upper floor and the lower floor in the embodiment comprises an inner ring beam 1 and an outer ring beam 2 which are oppositely arranged, the inner ring beam 1 is not in contact with the outer ring beam 2, a heat insulation cavity 5 is formed, and the heat insulation cavity 5 can prevent a cold and hot bridge from being formed between the inner ring beam and the outer ring beam. The cold and hot bridge comprises a cold bridge and a hot bridge, which are called south and north for the same phenomenon, when the building outer enclosure structure conducts heat with the outside, because the heat transfer coefficient of some parts in the enclosure structure is obviously larger than that of other parts, the heat is intensively and quickly transferred from the parts, thereby increasing the air conditioning and heating load and energy consumption of the building, and the phenomenon of condensation and frost formation in the room in winter is usually caused by the lintel ring beam (rectangular section which is not subjected to heat preservation treatment) of reinforced concrete. In order to increase the heat insulation effect and well prevent the formation of cold and hot bridge passages, heat insulation materials can be arranged in the heat insulation cavity 5 between the inner ring beam 1 and the outer ring beam 2, the heat insulation materials used in the building are various, and the most common heat insulation materials used in the building are two types: the inorganic heat-insulating material comprises expanded perlite, aerated concrete, rock wool, glass wool and the like; the organic heat-insulating material comprises polystyrene foam plastics, polyurethane foam plastics and the like.

Inner circle roof beam 1 be equipped with 3 fixed connection's of top wall board first last L type carriage 6 and with 4 fixed connection's of lower wall board first L type carriage 7, first last L type carriage 6 passes through third fastener 12 fixed connection top wall board 3, wallboard 4 under first L type carriage 7 passes through third fastener 12 fixed connection, first last L type carriage 6 and first L type carriage 7 between through 10 fixed connection of first fastener. For better connection, the first upper L-shaped connecting frame 6 and the first lower L-shaped connecting frame 7 are of a structure which is formed by bending a complete steel plate and is shaped like a Chinese character 'ji', namely the first upper L-shaped connecting frame 6 and the first lower L-shaped connecting frame 7 are of an integral structure.

The outer collar tie-beam 2 be equipped with 3 fixed connection's the second on L type carriage 8 of last wallboard and with lower wallboard 4 fixed connection's the second under L type carriage 9, L type carriage 8 passes through third fastener 12 fixed connection last wallboard 3 on the second, wallboard 4 under L type carriage 9 passes through third fastener 12 fixed connection under the second, through 11 fixed connection of second fastener between L type carriage 9 under L type carriage 8 and the second on the second. For better connection, the second upper L-shaped connecting frame 8 and the second lower L-shaped connecting frame 9 are of a structure which is formed by bending two complete steel plates and is in a shape like a Chinese character 'ji', namely the second upper L-shaped connecting frame 8 and the second lower L-shaped connecting frame 9 are of an integral structure.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
