Description

Technical Field

[0001] This invention relates to the field of wall panel technology, and more specifically to a prefabricated steel structure for wall panel installation. Background Art

[0002] Prefabricated partition walls typically consist of a prefabricated frame and panels. The frame is usually made of stainless steel plates, and the wall panels are then installed inside the steel plates. However, existing prefabricated buildings often have the following defects when installing wall panels: 1. The interior wall panels are usually installed by fixing them with screws, which results in poor installation and can only be installed at right angles; 2. Existing connecting components have poor connection effects when connecting interior wall panels, making the wall panels prone to shaking and resulting in poor seismic performance.

[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a prefabricated steel structure for wall panel installation that is easy to install, structurally stable, and prevents the wall panels from shaking.

[0005] The solution adopted by this invention to solve the technical problem is: a prefabricated steel structure for wall panel installation, including an installation frame, inner wall panels and outer wall panels. The installation frame includes an upper steel plate, a lower steel plate, a left steel plate and a right steel plate. Each of the upper steel plate, lower steel plate, left steel plate and right steel plate is provided with an E-shaped structure for installing the inner wall panels and outer wall panels. The installation groove includes an inner groove and an outer groove. The inner wall panels are installed in the inner groove and the outer wall panels are installed in the outer groove. Both the inner groove and the outer groove are provided with a tightening mechanism for pushing the inner wall panels and outer wall panels outward to ensure that wall panels of different thicknesses will not wobble when installed.

[0006] Furthermore, in order to form a telescopic structure for the clamping mechanism, the clamping support for the inner and outer wall panels can be adjusted according to the thickness of the inner and outer wall panels; the clamping mechanism includes a fixed column, a movable sleeve, a top plate, and a spring. The fixed column is fixedly installed in the mounting groove, the movable sleeve is movably sleeved on the fixed column, the top plate is installed on the outside of the movable sleeve, and the spring is sleeved on the movable sleeve.

[0007] Furthermore, to prevent the movable sleeve from popping out of the fixed post under the action of the spring force, the inner side of the fixed post is fixedly installed on the inner wall of the inner and outer grooves. The outer side of the fixed post is provided with a radially outward protruding limiting flange. The movable sleeve is telescopically sleeved on the fixed post. The inner side of the movable sleeve is provided with a radially inward protruding anti-detachment flange that cooperates with the limiting flange to prevent the movable sleeve from detaching from the fixed post. The diameter of the movable sleeve is slightly larger than the diameter of the limiting flange, and the inner diameter of the anti-detachment flange is smaller than the diameter of the limiting flange.

[0008] Furthermore, in order to support the inner and outer wall panels, improve the structural strength of the inner and outer wall panels, and thus improve the overall structural strength of the wall panels, the prefabricated steel structure for wall panel installation also includes a support mechanism for supporting the inner walls of the inner and outer wall panels. The support mechanism includes several cross-shaped support frames and a drive assembly for driving the cross-shaped support frames to move and support the inner walls of the inner and outer wall panels.

[0009] Furthermore, to provide adjustable support for the inner and outer wall panels based on their thicknesses, the drive assembly includes a main power group, an inner power group, and an outer power group. The main power group includes a power shaft, a worm gear, and a worm wheel. The power shaft is rotatably mounted on the left or right steel plate, and the worm gear is rotatably mounted between the left and right steel plates, with the power shaft perpendicular to the worm gear. A handle for rotating the power shaft is provided on the outer side of the power shaft extending beyond the left or right steel plate, and the inner side of the power shaft is coaxially fixed. Equipped with a driving bevel gear, the worm gear has a driven bevel gear located beside the driving bevel gear. The driving bevel gear and the driven bevel gear mesh with each other to drive the worm gear to rotate via a power shaft. There are several worm wheels, which are rotatably mounted on the mounting frame. The worm wheels are located on the upper and lower sides of the worm wheel respectively so that the worm gear can drive the worm wheel to rotate. The inner power group and the outer power group are both connected to the worm wheel transmission so that the worm wheel drives the cross-shaped support frame to move and press against the inner sidewalls of the inner wall panel and the outer wall panel respectively.

[0010] Furthermore, in order to drive the cross-shaped support frame to press against the inner wall of the inner wall panel, the inner drive assembly includes a screw, a screw seat, and a guide seat for guiding the screw seat to move back and forth. The screw is coaxially and fixedly connected to the worm gear. The screw seat is threaded onto the screw. The guide seat is located beside the screw and has a guide groove extending back and forth. The screw seat is slidably installed in the guide groove. The cross-shaped support frame is installed on the screw seat so that when the screw rotates with the worm gear, it drives the screw seat to move back and forth along the guide groove, causing the cross-shaped support frame to press against the inner wall of the inner wall panel.

[0011] Furthermore, in order to drive the cross-shaped support frame to press against the inner wall of the outer wall panel, the external drive assembly includes a rotating shaft, a slider, and a sliding block. The rotating shaft is coaxially fixedly mounted on the worm gear. The sliding block is located beside the rotating shaft and has a sliding groove extending forward and backward. The rotating shaft has a spiral groove. One end of the slider is slidably mounted in the sliding groove, and the other end of the slider is slidably mounted in the spiral groove. The cross-shaped support frame is mounted on the slider so that when the rotating shaft rotates with the worm gear, it drives the slider to move forward and backward along the sliding groove, causing the cross-shaped support frame to press against the inner wall of the outer wall panel.

[0012] Furthermore, in order to install the support mechanism, mounting rods are horizontally installed between the left and right steel plates on the upper and lower sides of the worm gear. Several worm gear shafts are rotatably mounted on the mounting rods via bearings. The worm gears are coaxially fixedly mounted on the worm gear shafts. One end of the worm gear shaft is fixedly connected to the rotating shaft, and the other end of the worm gear shaft is fixedly connected to the screw.

[0013] Both the left and right steel plates are provided with square mounting seats. Both ends of the mounting rod are provided with inverted U-shaped grooves for engaging the square mounting seats. Both the square mounting seats and the inverted U-shaped grooves are provided with pin holes for horizontally installing pins to fix the mounting rod on the square mounting seats.

[0014] Furthermore, in order to improve the structural strength of the installation frame, reinforcing ribs are installed at an angle between the left and upper steel plates, between the left and lower steel plates, between the right and upper steel plates, and between the right and lower steel plates to enhance the structural strength of the installation frame.

[0015] Furthermore, in order to adjust the supporting force of the reinforcing rib on the upper steel plate, lower steel plate, left steel plate, and right steel plate, the reinforcing rib includes an upper rib, a lower rib, and an adjusting cone disposed between the upper and lower ribs for adjusting the tension of the reinforcing rib. The upper rib is welded to the upper and lower steel plates, and the lower rib is welded to the left and right steel plates. Both the upper and lower ribs have inclined surfaces with the same inclination as the adjusting cone on the side near the adjusting cone. The adjusting cone is slidably installed between the inclined surfaces of the upper and lower ribs. The adjusting cone has a radially outwardly extending limiting block. Both the inclined surfaces of the upper and lower ribs have limiting grooves, and the limiting block is slidably installed in the limiting grooves.

[0016] Adjustment frames are provided on both sides of the upper and lower steel plates. Adjustment screws are rotatably installed on the adjustment frames. Adjustment cones are threaded onto the adjustment screws so that by rotating the adjustment screws, the adjustment cones can be driven to move and engage between the inclined surfaces of the upper and lower ribs, thereby adjusting the supporting force of the upper and lower ribs on the upper, lower, left, and right steel plates.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] (1) This invention is easy to install and has high structural strength. By forming a double wall panel installation structure with inner and outer wall panels on the installation frame, the structural strength of the wall panel is improved, and the sound insulation and absorption effect of the wall panel is also improved. In addition, the installation groove on the installation frame adopts an adjustable installation structure, which can flexibly install wall panels of different thicknesses and has a wide range of applications.

[0019] (2) The present invention uses a cross-shaped support frame to support the inner side wall of the wall panel, which prevents the inner and outer wall panels from shaking and also improves the structural strength of the wall panel. In addition, the cross-shaped support frame adopts an adjustable installation structure, which can also adapt to wall panels of different thicknesses.

[0020] (3) The present invention also adopts an adjustable tension reinforcing rib structure. By rotating the adjusting screw, the adjusting cone is driven to move, which can adjust the squeezing force of the adjusting cone on the upper and lower reinforcing ribs, thereby changing the tension of the reinforcing rib, adjusting the supporting force on the mounting frame, and further strengthening the structural strength of the mounting frame.

Furthermore, the installation groove on the installation frame 1 adopts an adjustable installation structure, which can flexibly install wall panels of different thicknesses, making it widely applicable. This invention uses a cross-shaped support frame 51 to support the inner sidewall of the wall panel, preventing the inner wall panel 2 and outer wall panel 3 from shaking while also improving the structural strength of the wall panel. Moreover, the cross-shaped support frame 51 adopts an adjustable installation structure, which can also accommodate wall panels of different thicknesses.
