Description

Technical Field

[0001] The utility model relates to the technical field of building walls, in particular to a connecting piece, an inner wall frame and an assembled inner wall structure thereof. Background Art

[0002] At present, the existing building walls in my country usually adopt the construction method of supporting formwork on the construction site, pouring concrete and then removing the formwork. This method has heavy walls, slow construction speed and much waste of materials. With the rapid development of my country's residential industry, it has gradually failed to meet the efficient and simple design concept advocated by modern new technologies. With the development of new building industrialization and intelligent construction, the application research of new prefabricated buildings with multi-functional integration such as environmental protection, energy saving and thermal insulation is being widely carried out.

[0003] At present, the threaded metal rod connectors used in the insulation walls in the market can meet the tensile strength of the inner and outer leaf walls, but due to the large thermal conductivity of metal, a thermal bridge is formed in the wall, which increases the heat loss of the wall, and the contact area between the threaded metal rod and the wall panel is small, and the stability after connection is poor; and the connectors between the walls are independently set. Although the connectors can fix the wall panels on both sides well in the horizontal direction, the tensile performance of the connectors on the wall panels in the vertical direction is weak, and the longitudinal strength of the wall is poor. During the concrete pouring construction, if the impact load of the concrete is too large, the vibration time is too long, and the reinforcement is not in place, it is very easy to cause the longitudinal deformation of the wall panels during the concrete pouring process, and the subsequent processing is more cumbersome. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a connecting piece, an inner wall frame and an assembled inner wall structure thereof.

[0005] The utility model is realized through the following technical scheme: a connecting piece, comprising a connecting portion and a fixing portion, wherein both ends of the connecting portion in the length direction expand and extend in a direction away from the connecting portion to form the fixing portion, and the cross-sectional area of ​​one end of the fixing portion away from the connecting portion is larger than the cross-sectional area of ​​the end portion of the connecting portion.

[0006] In this solution, the end of the connecting part extends outward to form a fixed part, and the cross-sectional size of the rear end is increased, thereby increasing the contact area with the wall, so that the connection between the connecting piece and the wall is more stable.

[0007] As an optimization, the two sides of the end face of the connecting portion extend in a direction away from the connecting portion and sequentially form a first side and a second side of the fixing portion, the two first sides are tilted in a direction away from each other, the two second sides are relatively parallel, the ends of the two second sides are connected to form a third side of the fixing portion, and the third side is parallel to the end face of the connecting portion. In this optimization solution, the first sides are tilted away from each other to increase the end face size of the connecting portion, and the third side is parallel to the end face of the connecting portion, so that the side plates connected at both ends of the connector are relatively parallel.

[0008] As an optimization, the top surface of the connection part is provided with two recessed grooves, and the two ends of the recessed grooves penetrate the connection part along the width direction of the connection part. This optimization solution facilitates the engagement of the connection piece by providing recessed grooves on the connection part.

[0009] An inner wall frame comprises the connecting member described in any embodiment of the present application and two oppositely arranged side panels, a casting cavity is formed between the two side panels, the connecting member is distributed along the length direction of the casting cavity, the two ends of the connecting member are respectively fixedly connected to the two side panels, and also includes a connecting piece, which extends along the distribution direction of the connecting member and is fixedly connected to the connecting member.

[0010] This solution uses a connector to connect and fix the two side panels to form a casting cavity, which is easy to assemble. The connector in the casting cavity is fixed by a connecting piece to make the connector a whole. The connector connected as a whole greatly improves the longitudinal tensile strength of the side panel. The two side panels are more stable after being connected by the connector, thereby enhancing the overall structural strength of the inner wall frame.

[0011] As an optimization, at least two layers of connectors are distributed in the casting cavity along the height direction, and the number of connectors in each layer is set to a certain number, and all connectors in the same layer are connected as a whole through the same connecting piece. In this optimization scheme, multiple layers of connectors are arranged in the height direction of the casting cavity, further enhancing the stability and strength of the connection to the inner wall skeleton.

[0012] As an optimization, the cross section of the connecting piece includes a first horizontal side, and the two ends of the first horizontal side are bent on the same side to form a first vertical side adapted to the sink groove of the connecting piece, and the two first vertical sides are respectively embedded in the two sink grooves. The two vertical sides of the connecting piece of this optimization solution are engaged in the sink groove, so that the connection between the connecting piece and the connecting piece is more tightly connected, further improving the overall structural strength.

[0013] As an optimization, a vertically extending reinforcement is fixed to the inner wall of the side panel, and the two ends of the connecting member are respectively fixed to the reinforcements on the two side panels. This optimization solution reinforces the side panels with reinforcements to prevent the side panels from deforming due to mold expansion during pouring. At the same time, the connecting member and the reinforcement are fixed to make the connection between the connecting member and the side panel more stable.

[0014] As an optimization, the cross section of the reinforcement includes a second horizontal side fixedly connected to the inner wall of the side panel, the two ends of the second horizontal side are bent on the same side to form a second vertical side, the fixing portion is embedded between the two second vertical sides and fixedly connected to the second vertical sides, and the ends of the two second vertical sides are bent in a direction away from each other to form a third horizontal side. The reinforcement of this optimization solution fixes the side panel through the second horizontal side, and the fixing portion of the connector is engaged with the two second vertical sides, so that the connection between the connector and the reinforcement is more stable. After pouring concrete in the casting cavity, the two third horizontal sides are engaged in the formed concrete, so that the connection between the reinforcement and the wall is more tightly connected, thereby enhancing the strength of the wall structure.

[0015] As an optimization, seepage holes are provided on the side plates, penetrating the side plates in the thickness direction of the side plates. In this optimization scheme, slurry can seep out through the seepage holes when pouring concrete, thus avoiding incomplete pouring in the pouring cavity.

[0016] An assembled inner wall structure comprises a plurality of inner wall frames as described in any one of the embodiments of the present application, wherein the plurality of inner wall frames are distributed circumferentially, the corners of the circumferentially adjacent inner wall frames are connected and fixed by right-angle fixing members, and the casting cavities of the adjacent inner wall frames are connected, and concrete is poured in the casting cavities.
