Description

Technical Field

[0001] The invention relates to the technical field of building external frame construction, and more specifically, to a convenient building external frame wall connecting member and a construction method. Background Art

[0002] Wall ties are important components for ensuring the safety factor of external frames. At present, the construction method of wall ties used for safety external frames is to embed steel bars into the concrete structure and then connect them to the safety external frame through steel pipes. However, the above construction method has the following technical defects in the secondary structure masonry construction: First, the original embedded steel bars affect the masonry construction and form masonry cavities at the embedded locations. After the safety external frame is removed, the masonry cavities cannot be effectively sealed, which affects the quality of masonry construction and makes it very easy for rainwater to leak here, which has a serious impact on the subsequent waterproofing construction. Second, the original embedded steel bars are rigidly connected to the steel pipes of the safety external frame. If the installation angle of the embedded steel bars is offset, it will directly cause the steel pipes connected to the safety external frame to be displaced, affecting the installation quality of the safety external frame. Summary of the invention

[0003] In view of the above technical problems, the purpose of the present invention is to provide a convenient building external frame wall connecting piece, which aims to use pre-embedded PVC screw sleeves for the pre-embedded installation of the wall connecting piece, so that it can be constructed without penetrating the outer structure of the building, avoiding holes in the building layers and secondary repairs, and eliminating the hidden dangers of external wall leakage; at the same time, there is a degree of rotation freedom between the wall connecting piece and the safety external frame, which can effectively solve the technical problem of the unadjustable connection with the safety external frame after the pre-embedded wall connecting piece, and significantly improve the installation quality of the safety external frame.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A convenient building external frame wall connecting member, comprising

[0006] A nut, wherein a screw sleeve is wrapped around the outer periphery of the nut to form a pre-embedded wall connection kit;

[0007] a connecting screw rod, one end of which is sleeved in the screw rod sleeve and connected with the nut, and the other end of which extends out of the embedded structural beam or the outside of the wall;

[0008] A connector steel pipe is hinged with one end of the connector steel pipe and the connecting screw rod extending out of the structural beam or the outside of the wall, so that there is rotational freedom between the wall connecting member and the safety external frame.

[0009] The implementation principle of this technical solution: This technical solution adopts embedded screw sleeves, which can be constructed without penetrating the outer structure of the building. The connecting screw is inserted into the screw sleeve to form a detachable fixed connection with the nut. After the outer structure of the building is completed, the embedded wall connection kit can form a closed embedded cavity in the structural beam or wall, avoiding holes in the building layer and secondary repairs, and eliminating the hidden dangers of external wall leakage; at the same time, a convenient building external frame wall connection piece is used for fixed positioning to ensure that the wall connection piece and the safety external frame have rotational freedom, which can effectively solve the technical problem of the unadjustable connection with the safety external frame after the embedded wall connection piece is installed. Even if the installation angle of the embedded steel bar is offset, it will not affect the installation quality of the safety external frame. The wall connection piece is flexible and convenient to install and disassemble, which can significantly improve the installation quality of the safety external frame.

[0010] As a preferred solution, a universal connector is provided at the end of the connecting screw, the connecting screw is fixedly connected to the universal connector, and the connector steel pipe is rotatably connected to the universal connector through a pin. The universal connector is used to connect the connector steel pipe and the connecting screw, which has accurate positioning, good fixing strength, and convenient installation, and is easy to replace the connector steel pipe.

[0011] As a preferred solution, the universal connector is a "U"-shaped fastener, and the "U"-shaped fastener includes a bottom section and two side sections connected to the bottom section, the connecting screw is fixedly connected to the bottom section, and the end of the connector steel pipe extends between the two side sections and allows the pin to pass through the two side sections and be connected to the connector steel pipe. The universal connector with the above structure has high structural strength and good fixing effect between the connector steel pipe and the connecting screw, so that the wall connection piece can be easily and flexibly disassembled and installed, and the wall connection piece and the safety external frame have flexible rotational freedom, which reduces the steel pipe connected to the safety external frame from being restricted by the connecting screw in the structure, and at the same time plays a role in conveniently fixing the building external frame. The structural design is ingenious and reasonable.

[0012] As a preferred solution, the two side sections are arranged perpendicularly to the bottom section, and the pin is arranged parallel to the bottom section. In this way, the pin and the "U"-shaped fastener form a rectangular frame structure to enhance the structural stability of the connecting screw and the connector steel pipe connecting section.

[0013] As a preferred solution, a first mounting hole is opened in the middle of the bottom section, and a stopper block having a size larger than the diameter of the mounting hole is provided at the end of the connecting screw, so that the connecting screw can pass through the first mounting hole through the "U"-shaped fastener and be fixed with the "U"-shaped fastener. With the above structure, a detachable, limited and fixed connection is formed between the connecting screw and the "U"-shaped fastener, which ensures the stability of the connection structure while achieving the effect of convenient installation and flexible and convenient disassembly.

[0014] As a preferred solution, a second mounting hole for the pin to pass through is provided at one end of the two side segments away from the bottom segment, and a radial through hole is provided in the center of the end of the connector steel pipe, so that the pin passes through the second mounting hole and the radial through hole on the connector steel pipe to be matched and connected with the connector steel pipe. The above structure forms a detachable and rotatable matching connection between the connector steel pipe and the "U"-shaped fastener, which ensures the stability of the connector steel pipe structure while achieving the effect of convenient installation and flexible and convenient disassembly, and is convenient for replacing the connector steel pipe.

[0015] As a preferred solution, the screw sleeve is a PVC screw sleeve, which is used to form a better seal in the structural beam or wall, eliminate the hidden danger of external wall leakage, avoid affecting the subsequent waterproof construction, and save labor costs.
