Description

Technical Field

[0001] The invention relates to the technical field of assembled building components, and in particular to an environmentally friendly assembled prefabricated component. Background Art

[0002] Prefabricated buildings refer to buildings that are assembled and installed by transporting factory-processed building components to the construction site. As the prefabricated components of prefabricated buildings are produced in a standardized manner, the construction efficiency is high and the construction period is short, so they are widely used in modern buildings. Shear walls are one of the important prefabricated components in prefabricated buildings. They are walls used to withstand horizontal and vertical loads caused by wind loads or earthquakes. At present, the connection between the shear wall and the lower component in the prefabricated building is as follows: the vertical steel bars on the lower component are inserted into the grouting sleeve at the bottom of the shear wall, and multiple support frames are installed on the shear wall for support and fixation, and then grouting is injected into the grouting sleeve, and the hardened grouting material is used to hold the steel bars and the grouting sleeve respectively to achieve a fixed connection.

[0003] The existing installation method of shear wall components only relies on the gripping effect of grouting materials. When strong winds or earthquake disasters occur, once the hardened grouting materials are damaged, the grouting sleeve of the shear wall may be separated from the steel bars, causing the wall to collapse. Therefore, the installation reliability and safety of shear wall components in prefabricated buildings need to be improved; in addition, since the wall and the lower components are not cast in one piece, water leakage is prone to occur at the joints of the later construction. Therefore, an environmentally friendly prefabricated component is needed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] See also Figure 1-9 , the present invention provides the following technical solutions:

[0033] An environmentally friendly assembled prefabricated component comprises: a steel skeleton 1, which is formed by binding and welding a plurality of horizontal and vertical steel bars; a grouting reinforcement component 2, which is welded to the inner lower side of the steel skeleton 1, and is used for grouting connection with the steel bars on other prefabricated components, and is used for bending and pulling the steel bars on other prefabricated components for reinforcement; the grouting reinforcement component 2 comprises a box body 21, a grouting sleeve 22 and a grouting branch pipe 23, the box body 21 is a rectangular structure with a hollow interior, and is welded to the steel skeleton 1, the grouting sleeve 22 is vertically welded to the bottom of the box body 21, the lower side wall of the grouting sleeve 22 is connected to the grouting branch pipe 23, the grouting sleeves 22 are arranged at intervals and staggered on the lower end surface of the box body 21, and the staggered distribution of the grouting sleeves 22 is conducive to increasing the area of ​​the connection area and improving the connection stability of the wall components.

[0034] A fixing and adjusting mechanism 24 is installed inside the box body 21, and a pressing and bending mechanism 25 is installed on the fixing and adjusting mechanism 24. The number and position of the pressing and bending mechanism 25 correspond to the grouting sleeve 22. The pressing and bending mechanism 25 is used to fix and bend the steel bars entering the grouting sleeve 22, and the fixing and adjusting mechanism 24 is used to lift and reinforce the steel bars.

[0035] The fixed adjustment mechanism 24 includes an adjustment plate 241, a lifting adjustment screw 242 and a driven bevel gear 243. The adjustment plate 241 is vertically slidably connected to the box body 21. The lifting adjustment screw 242 is vertically rotatably connected in the box body 21. The lifting adjustment screw 242 is threadedly connected to the threaded hole on the adjustment plate 241. The lifting adjustment screw 242 is keyed to the driven bevel gear 243. The inner wall of the box body 21 is provided with a first support 244. The first support 244 is rotatably connected with an adjustment shaft 245. One end of the adjustment shaft 245 is connected to an active bevel gear 246 that meshes with the driven bevel gear 243. The purpose of setting the fixed adjustment mechanism 24 is to control the adjustment plate 241 to drive the pressing and bending mechanism 25 to move upward, so that the pressing and bending mechanism 25 pulls up the steel bars, so that the connection between the wall components and the lower components is tighter and more stable.

[0036] The compression and bending mechanism 25 includes a mounting frame 251, a steel bar fixing block 252 and a clamping bolt 253. The mounting frame 251 is mounted on the lower end surface of the adjustment plate 241. The steel bar fixing block 252 is rotatably connected to the mounting frame 251. A through hole for the steel bar to pass through is provided in the middle of the steel bar fixing block 252. The threaded hole in the side wall of the steel bar fixing block 252 is threadedly connected with a clamping bolt 253. The clamping bolt 253 is used to compress and fix the steel bar. 25 also includes a driving mechanism for driving the steel bar fixing block 252 to rotate and bend the steel bar; there are two types of compression and bending mechanisms 25, and their main structures are the same. In order to adapt to different bending directions of the steel bars, the compression bolts 253 of the two compression and bending mechanisms 25 are installed in different directions; the compression and bending mechanism 25 can be used to perform reverse staggered bending on the steel bars at the upper end of the grouting sleeve 22. Even if the hardened grouting material is damaged, the bent steel bars are not easy to fall out of the grouting sleeve 22, thereby ensuring the connection stability of the wall.

[0037] The driving mechanism includes a driving frame 254, a vertical groove 255 and an internal threaded sleeve 256. The driving frame 254 is welded to the side of the steel bar fixing block 252. The upper end of the driving frame 254 is provided with a vertical groove 255. The internal threaded sleeve 256 is slidably connected to the vertical groove 255 through a convex block on the side. A second support 257 is welded to the box body 21. A bending driving screw 258 is rotatably connected between the second support 257 and the mounting frame 251. The bending driving screw 258 is threadedly connected to the internal threaded sleeve 256. A plurality of construction pipes 26 are provided on the side of the box body 21. One end of the construction pipe 26 extends to be flush with the surface of the concrete coating layer 3. A tool is used to enter the box body 21 through the construction pipe 26 to rotate the bending driving screw 258 to realize the driving of the compression and bending mechanism 25. In addition, the provision of the construction pipe 26 can prevent concrete from entering the box body 21 when pouring the concrete coating layer 3.

[0038] A concrete covering layer 3 is covered on the steel skeleton 1 and the grouting reinforcement component 2 to form a concrete wall; a building sealing pad 4 is provided on the bottom surface of the concrete covering layer 3. Through the cooperation of the building sealing pad 4, the compression and bending mechanism 25 and the fixing and adjusting mechanism 24, the connection pressure between the wall component and the lower component can be increased, the stable sealing of the building sealing pad 4 is ensured, and the waterproof performance of the connection between the components is improved.

[0039] The working process of the present invention is as follows:

[0040] When the prefabricated wall components need to be assembled, the wall is first hoisted to the installation position so that the grouting sleeve 22 at the lower end of the wall is aligned with the steel bar position on the lower component, and the wall is slowly lowered so that the steel bar enters the grouting sleeve 22, and the upper end of the steel bar enters the through hole of the steel bar fixing block 252 at the same time; a tool is used to extend into the box body 21 through the construction pipe 26, and each clamping bolt 253 is rotated so that the end of the clamping bolt 253 is pressed against the surface of the steel bar to fix the steel bar.

[0041] After the steel bars are fixed, each bending drive screw 258 is rotated, and the bending drive screw 258 drives the internal threaded sleeve 256 to move, so that the internal threaded sleeve 256 drives the steel bar fixing block 252 to rotate through the driving frame 254, thereby realizing the bending processing of the upper end of the steel bar; then the adjusting shaft 245 is rotated, and the adjusting shaft 245 drives the lifting and lowering adjusting screw 242 to rotate through the active bevel gear 246 and the driven bevel gear 243, so that the lifting and lowering adjusting screw 242 drives the adjusting plate 241 to move upward, and the lifting equipment synchronously lowers the wall until the bottom surface of the wall contacts the lower component, and the lifting and lowering adjusting screw 242 is continued to be rotated to press and fix the wall component and the lower component.

[0042] By inputting grouting material into each grouting branch pipe 23, the grouting material fills each grouting sleeve 22 and then enters the box body 21. After filling, the grouting material flows out from the construction pipe 26, and the construction pipe 26 is blocked with a rubber plug until grouting material flows out of each construction pipe 26, and the grouting construction is completed. After the box body 21 is filled with grouting material, the stability of the compression and bending mechanism 25 and the fixing and adjusting mechanism 24 is further enhanced, that is, the stable assembly connection of the wall components is achieved.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
