Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an external frame wall connecting piece. Background Art

[0002] With the rapid development of my country's construction technology, strengthening safety and quality management and promoting green and civilized construction have become the dominant ideas in the current construction environment. As a temporary component that allows construction workers to operate at different locations at high altitudes and ensures the safety of construction workers during operation, external scaffolding has a high application rate in the construction field. One of the key points for the stability and reliability of external scaffolding is the wall connecting parts that connect the external scaffolding to the main building structure. The traditional wall connecting part method is: when the structure is poured, a short vertical steel pipe parallel to the external frame pole is embedded, and then a short horizontal steel pipe and three cross fasteners are respectively fixed to the embedded vertical steel pipe and the external frame pole, forming a rigid connection between the main structure and the external frame, so as to achieve the purpose of stabilizing the external frame.

[0003] However, traditional wall ties have many drawbacks and still cannot keep up with the requirements of current construction technology. For example, the vertical steel pipes pre-buried in the structure of traditional wall ties can only be cut when the external frame is dismantled, which wastes materials; the horizontal steel pipes used to connect the external frame uprights in the traditional wall ties affect the exterior wall construction, and only holes can be left during masonry for later repairs, resulting in poor molding quality; when the traditional wall ties enter the facade decoration stage, workers like to dismantle the wall ties privately because they want to complete the task in one go, which poses a major safety hazard.

[0004] In the "an external frame wall connection member that can be pre-buried" disclosed in the publication number CN217782823U, it includes a main body and a protective device. The main body is fixed on the surface of a steel pipe, the cross section of the steel pipe is cylindrical, and the protective device is arranged on the surface of the main body. The protective device includes an upper sleeve, the upper sleeve is slidably connected to the surface of the steel pipe, the longitudinal section of the upper sleeve is rectangular, the surface of the steel pipe is slidably connected with a lower sleeve, the longitudinal section of the lower sleeve is rectangular, the surface of the upper sleeve is fixedly connected with a collar, the cross section of the collar is rectangular, and the surface of the lower sleeve is fixedly connected with an insert, the cross section of the insert is rectangular. By setting up the protective device, the external frame wall connection member is effectively protected, and the practicability, safety and service life of the external frame wall connection member are improved; but its structure is complicated, and the installation and operation are relatively inconvenient, which reduces the construction efficiency of workers, thereby affecting subsequent construction operations. Summary of the invention

[0005] In order to overcome the defects in the above-mentioned prior art, an external frame wall connecting member is provided which is easy to install, does not affect subsequent construction work, reduces safety hazards, has a simple structure, and reduces costs and increases efficiency.

[0006] The technical solution of the utility model is as follows: an external frame wall connecting member: including a connecting screw, one end of the connecting screw is screwed with an embedded sleeve rod embedded in the main structure beam, and the other end of the connecting screw is installed with a buckle assembly for fixing the external frame steel pipe.

[0007] Preferably, the buckling assembly includes a first buckling part, a second buckling part, a rotating shaft and a locking assembly; the first buckling part and the second buckling part are movably connected via the rotating shaft, and the locking assembly is assembled at one end of the second buckling part away from the rotating shaft.

[0008] Preferably, the first fastener, the second fastener and the rotating shaft are connected to form a fixing hole for fixing the outer frame steel pipe.

[0009] Preferably, the locking assembly includes a locking screw and a locking nut; the locking screw is assembled in a second circular hole provided in the second fastener, and the locking nut is threadedly connected to the locking screw.

[0010] Preferably, the first fastening member is provided with a fastening groove for fastening with the locking screw, and the locking nut is used to lock the locking screw in the fastening groove.

[0011] Preferably, the embedded sleeve rod includes an internal nut and a rubber sleeve; the internal nut is installed at the bottom end of the rubber sleeve to fix the rubber sleeve.

[0012] Preferably, the connecting screw passes through a first circular hole provided in the second fastening member, and an external hexagonal end is provided at the end of the connecting screw.

[0013] Preferably, the inner diameter of the first circular hole is smaller than the diameter of the external hexagonal end cap.

[0014] Preferably, a gasket is installed at the connection between the second circular hole and the locking screw.

[0015] Preferably, both the first fastening member and the second fastening member are provided with mounting holes for mounting the rotating shaft.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] An external frame wall connecting piece connects the embedded sleeve rod and the buckle assembly through connecting screws to ensure a stable connection between the building external frame and the main structure. The buckle assembly is used to fix the external frame steel pipe to prevent the external frame from shaking or moving under the action of wind or other external forces, thereby improving the stability and safety of the entire building structure; the entire device has a simple structure and is easy for workers to install and disassemble.

[0018] Furthermore, the buckle assembly can adapt to different sizes and shapes of the external frame steel pipe. The first buckle and the second buckle are movably connected through a rotating shaft and rotate around the rotating shaft. The locking assembly ensures that the first buckle and the second buckle are firmly connected, thereby improving the connection stability and safety between the external frame steel pipe and the main structure.

[0019] Furthermore, the fixing hole is a channel formed by the first fastener, the second fastener and the rotating shaft, which is used to accommodate and fix the external frame steel pipe. When the external frame steel pipe is placed in the fixing hole formed by the first fastener and the second fastener, the external frame steel pipe will be firmly clamped and fixed; the installation process is simplified, the construction efficiency is improved, and the safety hazards caused by loosening or displacement are reduced.

[0020] Furthermore, the locking assembly ensures the stability and reliability of the first fastening member and the second fastening member after fixing the outer frame steel pipe through the coordinated work of the locking screw and the locking nut, thus simplifying the installation process and improving the safety and durability of the connection.

[0021] Furthermore, through the buckling groove, the connection between the locking screw and the first buckling member is more stable, reducing the risk of loosening or displacement. The shape and size of the groove ensure that the locking screw can be accurately placed therein, thereby simplifying the installation process. Since the locking screw is firmly buckled in the groove, the bearing capacity of the entire buckling assembly is improved, and it can better withstand external forces.

[0022] Furthermore, the built-in nut allows the connecting screw to be conveniently screwed onto the embedded sleeve rod, thereby simplifying the installation process, improving installation efficiency, and enhancing the stability and durability of the connection.

[0023] Furthermore, the first circular hole allows the connecting screw to smoothly pass through the second fastening member, thereby connecting with other parts of the fastening assembly, making it convenient for workers to install and adjust.

[0024] Furthermore, the external hexagonal end prevents the connecting screw from moving or rotating in an unwanted direction, thereby ensuring the accuracy and stability of the connection; since the external hexagonal end cannot pass through the first circular hole, it becomes a stopper to prevent the connecting screw from accidentally falling off from the second fastening member. This design increases the safety of the connection and ensures the correct positioning of the connecting screw in the fastening assembly.

[0025] Furthermore, a gasket is installed at the connection between the second circular hole and the locking screw to increase the contact area and disperse the pressure of the locking screw on the second circular hole, thereby reducing the concentration and wear of local stress. By installing the gasket, the second circular hole can be effectively protected from direct wear of the locking screw, thereby extending the service life of the second circular hole. At the same time, the gasket can also adjust the gap between the locking screw and the second circular hole to ensure the stability and reliability of the locking assembly.

[0026] Furthermore, the correct installation hole position and size can ensure that the shaft is installed smoothly and firmly fixed, thereby avoiding problems such as loosening or displacement during use, making it easier for workers to install and improving installation efficiency.

The external frame wall connection piece can be firmly connected to the main structure beam through the connecting screw 1.

[0040] Among them, the second fastening member 3-2 is provided with a first circular hole 3-2-1 and a second circular hole 3-2-2, and the end of the connecting screw 1 is provided with an external hexagonal end cap 1-1; the inner diameter of the first circular hole 3-2-1 is smaller than the diameter of the external hexagonal end cap 1-1, which is convenient for the connecting screw 1 to pass through the first circular hole 3-2-1 and connect with the fastening component 3. The external hexagonal end cap 1-1 ensures the correct installation and positioning of the connecting screw 1 in the fastening component 3, prevents accidental falling off, and facilitates workers to use tools for installation and adjustment.

[0041] The fastening assembly 3 includes a first fastening member 3-1, a second fastening member 3-2, a rotating shaft 3-3 and a locking assembly 3-4; the first fastening member 3-1 and the second fastening member 3-2 are movably connected through the rotating shaft 3-3, and the first fastening member 3-1, the second fastening member 3-2 and the rotating shaft 3-3 are connected to form a fixing hole 4 for fixing the external frame steel pipe.
