Description

Technical Field

[0001] This utility model relates to the field of assembled metal connection technology, specifically to an assembled metal connector shear reinforcement device. Background Technology

[0002] Prefabricated buildings are a construction mode that uses prefabricated components in a factory as the core and completes the construction through on-site assembly. This construction mode greatly reduces the construction time and is therefore often used in large-scale infrastructure construction. Traditional assembly components usually use bolts to fix the main frame, but bolt-fixed assemblies have low shear resistance and are prone to deformation.

[0003] To increase the shear resistance at the joints of the assembly and prevent deformation, users install connectors at the joints. When installing the frame, the connectors are fixed to the assembly by bolts. Therefore, the smaller the gap between the connector and the assembly, the better the shear resistance. However, the smaller the dimensional difference between the assembly and the connector, the more difficult it is to insert the assembly into the connector during installation, which in turn increases the difficulty of assembly installation. Utility Model Content

[0004] The purpose of this utility model is to provide a shear reinforcement device for assembled metal connectors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated metal connector shear reinforcement device, comprising: an assembly body, wherein four sets of mounting brackets are uniformly welded and fixed around the perimeter of the assembly body, and the mounting brackets are symmetrically provided with moving grooves inside, and bidirectional lead screws are symmetrically rotatably connected inside the moving grooves.

[0006] The movable slot is slidably connected to a movable fixing plate, and the movable fixing plate is threadedly connected to a bidirectional lead screw.

[0007] A mounting frame is provided above the mounting bracket. The mounting frame has a mounting groove inside. Inside the mounting groove, corresponding to the position of the bidirectional lead screw, there are four sets of first bevel gears that rotate through bearings. The top of the first bevel gears meshes with second bevel gears. A first connecting rod is welded and fixed between the two sets of second bevel gears. The first connecting rod passes through the mounting frame and its end face is fixed with a worm gear by bolts. A worm is provided below the worm gear. A second connecting rod is welded and fixed between the two sets of worms.

[0008] Preferably, the top of the bidirectional lead screw passes through the mounting bracket and has an insertion port on its end face.

[0009] Preferably, the movable fixing plate has a through-hole for fixing screws.

[0010] Preferably, one end of the second connecting rod passes through the mounting frame and a handle is welded and fixed to the end face.

[0011] Preferably, the bottom of the first bevel gear is fixed with a plug rod through the end face of the mounting frame by bolts, and the plug rod is movably engaged inside the socket.

[0012] Preferably, the main body of the assembly has through-holes for mounting screws.

[0013] Preferably, the mounting bracket has symmetrically welded and fixed clamping plates on both sides, and a storage frame is movably attached to the top of the clamping plates for storing bolts.

[0014] This utility model provides a prefabricated metal connector shear reinforcement device, which has the following beneficial effects:

[0015] (1) This utility model uses the mechanism inside the mounting frame to drive the four-way double screw to rotate, so that the user can adjust the position of the movable fixing plate according to the situation. When the side bracket needs to be installed, the user can adjust the position of the movable fixing plate so that the side bracket can be put into the mounting frame more easily. After the installation is completed, the user can adjust the position of the movable fixing plate so that the gap between the movable fixing plate and the side bracket is reduced, thereby making the shear resistance of the assembly better. At the same time, the position of the movable fixing plate can be freely adjusted so that the shear resistance is enhanced without increasing the installation difficulty between the side bracket and the mounting frame.

[0016] (2) This utility model uses a card plate to attach a storage frame. The storage frame is used to place bolts used for installation and prevents the bolts from falling off during use. The inside of the storage frame is equipped with a magnetic material that can attract the bolts, reducing the frequency of the bolts shaking inside the storage frame and thus reducing the probability of the bolts falling off the storage frame during use.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: Referring to 1-4, in this embodiment, a prefabricated metal connector shear reinforcement device includes: an assembly body 1, four sets of mounting brackets 2 are uniformly welded and fixed around the circumference of the assembly body 1, the mounting brackets 2 are symmetrically provided with moving grooves 201 inside, and bidirectional screw rods 202 are symmetrically rotatably connected inside the moving grooves 201; a moving fixing plate 203 is slidably connected inside the moving grooves 201, and the inside of the moving fixing plate 203 is threadedly connected to the bidirectional screw rods 202, the top of the bidirectional screw rods 202 passes through the mounting brackets 2 and the end face is provided with an insertion port 204, and the inside of the moving fixing plate 203 is provided with a fixing screw hole 205, and the moving fixing plate 203 moves according to the situation, so that when the moving fixing plate 203 is installed, the gap between the moving fixing plate 203 and the side bracket increases, thereby making it convenient for the user to insert the side bracket into the inside of the mounting bracket 2, thereby making it convenient for the user to install the side bracket inside the assembly body;

[0024] A mounting frame 4 is provided above the mounting bracket 2. The mounting frame 4 has a mounting groove 401 inside. Four sets of first bevel gears 402 are rotatably mounted inside the mounting groove 401 at positions corresponding to the bidirectional lead screw 202 via bearings. The tops of the first bevel gears 402 mesh with second bevel gears 405. A first connecting rod 406 is welded and fixed between the two sets of second bevel gears 405. The first connecting rod 406 passes through the mounting frame 4, and a worm gear 407 is bolted to its end face. A worm 4 is located below the worm gear 407. 09. A second connecting rod 408 is welded and fixed between the two sets of worm gears 409. One end of the second connecting rod 408 passes through the mounting frame 4 and a handle 404 is welded and fixed to the end face. The bottom of the first bevel gear 402 passes through the end face of the mounting frame 4 and is fixed with a plug rod 403 by bolts. The plug rod 403 is movably engaged inside the plug 204. The mounting frame 4 is equipped with a mechanism that can simultaneously drive four sets of bidirectional screws 202 to rotate synchronously, thereby driving the two sets of movable fixing plates 203 to move synchronously to clamp the side bracket.

[0025] The main body 1 of the assembly has a through-hole 101 for mounting screws. The mounting bracket 2 has symmetrically welded and fixed clamping plates 3 on both sides. The top of the clamping plate 3 is movably clamped to a storage frame 301. The storage frame 301 is used to store bolts. The storage frame 301 has a magnetic material inside, which can attract bolts and reduce the frequency of bolt shaking inside the storage frame 301, thereby reducing the probability of bolts falling out of the storage frame 301 during use.

[0026] This utility model provides a shear reinforcement device for assembled metal connectors, the specific working principle of which is as follows:

[0027] When installing the assembly frame, the user first takes out the main body 1 of the assembly, then takes out the corresponding main support bracket, inserts the main support bracket into the interior of the main body 1, and then aligns the bolt holes of the main support bracket with the mounting screw holes 101. The user then uses bolts to fix the main support bracket inside the main body 1. Next, the user takes out the mounting frame 4, aligns the insertion rod 403 at the bottom of the mounting frame 4 with the insertion port 204, and moves it downwards so that the insertion rod 403 engages inside the insertion port 204. Then, the user holds the handle 404 to rotate the two sets of worm gears 409. The rotation of the worm gears 409 drives the worm wheel 407 to rotate, which in turn drives the four sets of second bevel gears 405 to rotate. The second bevel gears 405 drive the first bevel gears 402 to rotate, and the rotation of the four sets of first bevel gears 402 will... The four sets of bidirectional lead screws 202 are rotated, which in turn causes the two sets of movable fixing plates 203 to move, making the distance between the two sets of movable fixing plates 203 greater than the width of the side bracket. Then, the user holds the side bracket and inserts it into the two sets of movable fixing plates 203, and adjusts the position of the side bracket so that the bolt holes of the side bracket coincide with the fixing screw holes 205. Then, the user holds the handle 404 and drives the worm gear 409 to rotate. The rotation of the worm gear 409 drives the worm wheel 407 to rotate, which in turn drives the four sets of bidirectional lead screws 202 to rotate, which in turn drives the two sets of movable fixing plates 203 to move, so that the movable fixing plates 203 clamp the side bracket. Finally, the bolts are removed to fix the movable fixing plates 203 to the side bracket. Finally, the above steps are repeated to install the side brackets in other directions into the movable fixing plates 203.

[0028] When installing the side bracket, multiple sets of bolts are fixed. The bolts are small in size, and if they fall during installation, they are difficult to retrieve. The mounting bracket 2 has a clamping plate 3 on both sides. The top of the clamping plate 3 can be engaged with the storage frame 301. The storage frame 301 can hold the bolts, making it convenient for users to take and use the bolts.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
