Description

Technical Field

[0001] The invention relates to the technical field of interior partition walls, in particular to a light steel keel interior partition wall of a reinforced concrete frame structure building. Background Art

[0002] Lightweight steel keel internal partition wall is a non-load-bearing wall structure used to separate spaces inside buildings, and is widely used as partition wall in indoor spaces. Due to the light weight of the lightweight steel keel itself, compared with traditional partition methods such as brick walls, the lightweight steel keel internal partition wall greatly reduces the self-weight of the building. This is very beneficial for the structural design of the building, especially in high-rise buildings or buildings with certain restrictions on the structural bearing capacity, which can reduce the burden on the foundation and main structure. Although the lightweight steel keel is very light, it can withstand certain lateral loads and vertical loads through reasonable structural design and combination. For example, in a normal indoor use environment, it can withstand external forces such as people leaning on it and collisions with small furniture. Lightweight steel keels are usually made of galvanized steel and do not burn themselves. In addition, during the construction process, fireproof materials such as fireproof rock wool can be filled inside the keel to further improve the fireproof performance of the wall, which can prevent the spread of fire within a certain period of time, providing valuable time for personnel evacuation and fire rescue. By filling the space between the keels with sound insulation materials (such as glass wool, rock wool, etc.) and combining it with suitable decorative panels (such as double-layer gypsum boards), the sound insulation effect of the wall can be effectively improved. For example, using light steel keel interior partition walls in a residence can reduce the sound interference between adjacent rooms and provide a relatively quiet living environment.

[0003] During the actual installation of existing light steel keel interior partition walls, workers are required to manually measure the dimensions first, and then manually install the ground keels, top keels, vertical keels and horizontal keels on site. The traditional method of assembling the partition walls on site using individual parts is inefficient and wastes working time. In addition, the keels usually have sharp edges and corners, which can easily cause scratches to workers during the multiple placement and installation processes. Therefore, a new type of light steel keel interior partition wall is needed to solve the above problems. Summary of the invention

[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] refer to Figures 1 to 9 :

[0031] The light steel keel interior partition wall of a reinforced concrete frame structure building comprises a top frame 1, a bottom frame 8, a locking mechanism, an adjusting mechanism, a transmission mechanism and a connecting mechanism. There are two top frames 1 and two bottom frames 8 respectively. The adjacent sides of the two bottom frames 8 are hinged, and the adjacent sides of the two top frames 1 are hinged. The bottom of a top frame 1 located on the same side is hinged to the top of a bottom frame 8. Locking mechanisms are arranged at the hinges of the bottom frame 8 and the top frame 1. The locking mechanisms are used to fix the bottom frame 8 and the top frame 1 when the bottom frame 8 and the top frame 1 are extended. The adjusting mechanism comprises a telescopic frame 3 slidably arranged in each bottom frame 8 and the top frame 1 and a telescopic output end for driving the telescopic frame 3 to extend or retract. The transmission mechanism comprises a connecting rod 11 rotatably arranged at the center of the bottom frame 8 and the top frame 1 and a rotating output end for driving the connecting rod 11 to rotate. The connecting mechanism is used to establish a connection between the connecting rod 11 in the top frame 1 and the connecting rod 11 in the bottom frame 8 when the top frame 1 is flipped, and the connecting rod 11 is transmission-connected to the telescopic output end.

[0032] It should be noted that the entire inner partition wall frame (the inner partition wall frame is composed of two top frames 1 and a bottom frame 8) is in a folded state under normal conditions (refer to Figure 1 ), during the actual installation, the staff directly brought the folded inner partition wall to the construction site, and then unfolded it to form a complete inner partition wall skeleton (refer to the unfolding process Figure 2 , Figure 3 ), wait for the inner partition wall to be fully unfolded, and then fix the inner partition wall frame with fixing bolts (it should be noted that both the top frame 1 and the bottom frame 8 are provided with fixing bolts, which is a mature existing technology and will not be described in detail here), and then install sound insulation foam and wall panels on the unfolded inner partition wall frame. This foldable inner partition wall frame greatly shortens the construction time, and makes the frame that originally needs to be assembled one by one become modular assembly, thereby improving work efficiency. In the process of unfolding the inner partition wall frame, first unfold the two hinged bottom frames 8 and the top frame 1 (such as Figure 2 ), and then unfold the top frame 1 hinged on the bottom frame 8 (such as Figure 3), during the unfolding process, the locking mechanism locks the hinge of the inner partition wall frame, and when the inner partition wall frame is unfolded, the connecting mechanism connects the two connecting rods 11, and then the rotating output end of the transmission mechanism drives the connecting rod 11 to rotate, and the rotation of the connecting rod 11 drives the telescopic output end to move, and then drives the telescopic frame 3 to move, so as to realize the lateral telescopic expansion and contraction of the inner partition wall frame, ensuring that the entire inner partition wall frame can adapt to a variety of construction environments. And when the building needs to be demolished, the staff can remove the excess sound insulation foam boards and wall panels and other materials, and after removing the fixing bolts, the staff first drives the connecting rod 11 to rotate through the transmission mechanism, and then the connecting rod 11 rotates to drive the telescopic output end to operate, so that the telescopic frame 3 is reset, and then the hinge of the inner partition wall frame is unlocked again through the locking mechanism, and then the entire inner partition wall frame is folded up again (such as Figure 1 ), so that the entire inner partition wall frame can be reused, achieving the purpose of energy saving and environmental protection, and also saving construction costs to a certain extent.

[0033] In order to show the structure of the bottom frame 8 and the top frame 1, the following features are also specifically set:

[0034] The bottom frame 8 includes a load-bearing transverse keel 9, a load-bearing vertical keel 10 fixedly arranged on the load-bearing transverse keel 9, two connecting transverse keels 17 fixedly arranged at one side of the load-bearing vertical keel 10 at equal intervals, a supporting keel 18 fixedly arranged on one end of the two connecting transverse keels 17 away from the load-bearing vertical keels 10, and a connecting vertical keel 19 fixedly arranged on the load-bearing transverse keel 9. The connecting vertical keel 19 penetrates the connecting transverse keel 17 close to the load-bearing transverse keel 9 and is fixedly connected to the connecting transverse keel 17 away from the load-bearing transverse keel 9. The structure of the top frame 1 is the same as that of the bottom frame 8. The two load-bearing vertical keels 10 in adjacent bottom frames 8 and two adjacent top frames 1 are hinged, and the load-bearing vertical keels 10 in the top frame 1 and the bottom frame 8 located on the same side are hinged, and connecting rods 11 are rotatably arranged in the load-bearing vertical keels 10.

[0035] In order to show the detailed structure of the telescopic frame 3, the following features are also specifically set:

[0036] The telescopic frame 3 includes a connecting keel 15, a movable keel 4, a first supporting keel 5 and a second supporting keel 16. There are two connecting keels 15, which are fixedly arranged at equal intervals on the side of the bearing vertical keel 10 away from the connecting transverse keel 17. There are three movable keels 4, one of which is slidably arranged in the bearing transverse keel 9, and the other two are respectively slidably arranged in the connecting keel 15. There are two first supporting keels 5, which are fixedly arranged at one end of the three movable keels 4 away from the bearing vertical keel 10. There are two second supporting keels 16, which are symmetrically fixedly arranged on both sides of the connecting keel 15 located in the middle position. The bottom end of one second supporting keel 16 is fixedly connected to the bearing transverse keel 9, and the top end of the other second supporting keel 16 is fixedly connected to the top connecting keel 15. The movable keel 4 is connected to the telescopic output end.

[0037] When the device is running, the connecting rod 11 rotates to drive the telescopic output end to run, and then the telescopic output end drives all the movable keels 4 to move along the length direction of the connecting keel 15, so that the telescopic frame 3 reaches the size required for actual construction.

[0038] In order to show the detailed structure of the telescopic output end, the following features are also set:

[0039] The adjustment mechanism also includes a rotating support plate 6, a threaded tube 7, a support tube seat 20 and a threaded rod 21. A plurality of rotating support plates 6 are fixedly arranged at equal intervals along the length of the two movable keels 4 located at the top and the bottom. The threaded tube 7 is fixedly arranged on all the rotating support plates 6 (such as Figure 6 As shown), the support pipe seat 20 is fixedly arranged in the load-bearing vertical keel 10, the threaded rod 21 is rotatably arranged on the support pipe seat 20 and penetrates the load-bearing vertical keel 10 and is threadedly connected to the threaded pipe 7, and the connecting rod 11 is transmission-connected to the threaded rod 21.

[0040] When the device is running, the connecting rod 11 drives the threaded rod 21 to rotate. The rotation of the threaded rod 21 causes the threaded tube 7 to move in the axial direction of the threaded rod 21 through the action of the thread, thereby causing the threaded tube 7 to drive the movable keel 4 to move.

[0041] The threaded tube 7 is the telescopic output end of the regulating mechanism.

[0042] In order to show the connection relationship between the connecting rod 11 and the threaded rod 21, the following features are also specifically provided:

[0043] The transmission mechanism also includes a plurality of supporting horizontal plates 14 fixedly arranged at equal intervals along the length direction of the supporting vertical keel 10, a toggle wheel 12 coaxially fixedly arranged on the connecting rod 11, a worm wheel 22 coaxially fixedly arranged on the end of the threaded rod 21 away from the threaded tube 7, and a worm 13 coaxially fixedly arranged on the end of the connecting rod 11 away from the toggle wheel 12. The worm 13 is meshed with the worm wheel 22, and the toggle wheel 12 is the rotation output end of the transmission mechanism.

[0044] When the device is running, a worker manually rubs the toggle wheel 12 to rotate, the rotation of the toggle wheel 12 drives the connecting rod 11 to rotate, the rotation of the connecting rod 11 drives the worm 13 to rotate, the rotation of the worm 13 drives the worm wheel 22 to rotate, and the rotation of the worm wheel 22 drives the threaded rod 21 to rotate.

[0045] In order to show the detailed structure of the connection mechanism, the following features are also set:

[0046] The connecting mechanism includes a sliding vertical groove 28 opened in each load-bearing vertical keel 10, a sliding plate 23 slidably arranged in the sliding vertical groove 28, a connecting chuck 25 coaxially fixedly arranged at the top end of the connecting rod 11 in the bottom frame 8, an adapter chuck 2 coaxially fixedly arranged at the bottom end of the connecting rod 11 in the top frame 1, a rotating sleeve 24 coaxial with the connecting rod 11 and rotatably connected to the sliding plate 23, a return spring 26 coaxially sleeved on the rotating sleeve 24, and a load-bearing support plate 43 arranged below the sliding plate 23 and fixedly connected to the load-bearing vertical keel 10, the rotating sleeve 24 is coaxially fixedly connected to the connecting chuck 25, the rotating sleeve 24 is key-connected to the connecting rod 11, one end of the return spring 26 is connected to the sliding plate 23, and the other end is connected to the load-bearing support plate 43.

[0047] When the load-bearing vertical keel 10 is turned over, the connecting chuck 25 and the adapter chuck 2 are clamped together, so that the two connecting rods 11 are connected, which facilitates the synchronous rotation of the two connecting rods 11 and ensures that the telescopic frame 3 can operate normally.

[0048] In order to show the detailed structure of the locking mechanism, the following features are also specifically set:

[0049] The locking mechanism includes positioning support plates 30 symmetrically arranged at both ends of the sliding plate 23, sliding arc grooves 31 opened on each positioning support plate 30, locking holes 34 opened on each positioning support plate 30, limiting support plates 35 symmetrically fixedly arranged on both sides of the vertical keel 10 supported in the top frame 1, and locking columns 36 elastically arranged on each limiting support plate 35.

[0050] During the process of the adapter chuck 2 and the connecting chuck 25 being clamped together, the load-bearing vertical keel 10 on the top frame 1 drives the limiting support plate 35 to move, and the movement of the limiting support plate 35 drives the locking column 36 to slide into the sliding arc groove 31 until the locking column 36 slides into the locking hole 34, and the adapter chuck 2 and the connecting chuck 25 are clamped together.

[0051] In order to ensure that the connecting chuck 25 and the adapter chuck 2 can be smoothly locked together during the process of the locking column 36 being inserted into the locking hole 34, the following features are also specifically provided:

[0052] Each limiting support plate 35 is provided with an installation groove 37, a bearing block 38 fixedly arranged in the installation groove 37, a telescopic block 39 elastically slidably arranged in the bearing block 38, a toggle block 41 rotatably arranged on each telescopic block 39 through a torsion spring, a limiting protrusion 40 arranged on the top of each toggle block 41 and fixedly connected to the telescopic block 39, a top extending inclined block 42 fixedly arranged on the telescopic block 39, a contact protrusion 27 fixedly arranged at both ends of the sliding plate 23, a contact protrusion 29 fixedly arranged on the side of each sliding vertical groove 28 and an unlocking strip 33 elastically slidably arranged on the positioning support plate 30.

[0053] (It should be noted that under normal conditions, the toggle block 41 is flipped upward and contacts the limit protrusion 40 under the action of the torsion spring) When the limit support plate 35 slides in the sliding arc groove 31 with the locking column 36, the toggle block 41 contacts the contact protrusion 27, thereby driving the sliding plate 23 to move downward along the sliding vertical groove 28, and then the sliding plate 23 drives the connecting chuck 25 and the rotating sleeve 24 to move downward. At this time, the return spring 26 is compressed, and the adapter chuck 2 continues to flip along the connecting rod 11 in the top frame 1. The connecting chuck 25 moves downward driven by the sliding plate 23 to avoid the adapter chuck 2, waiting for the top extending inclined block 42 to contact the contact protrusion 29, and the telescopic block 39 retracts into the bearing block 38, thereby driving The toggle block 41 separates from the contact convex plate 27, and then the sliding plate 23 is no longer under pressure, and then the reset spring 26 is reset, thereby driving the sliding plate 23 to move up and reset, and driving the connecting chuck 25 to move upward and clamp together with the adapter chuck 2. When the entire inner partition wall frame needs to be folded and disassembled, the unlocking strip 33 is pressed, and the unlocking strip 33 touches the locking column 36, so that the locking column 36 is squeezed out of the locking hole 34, and then the inner partition wall frame can be smoothly folded. Since the toggle block 41 is rotatably arranged in the telescopic block 39 by the torsion spring, when folding, the toggle block 41 will contact the contact convex plate 27, and the toggle block 41 will flip downward, thereby ensuring that the limit support plate 35 is smoothly withdrawn.

[0054] In order to ensure that the locking column 36 can slide smoothly into the sliding arc groove 31, the following features are also specifically provided:

[0055] A guiding slope 32 begins at the top of each sliding arc groove 31 .

[0056] When the limiting support plate 35 slides into the sliding arc groove 31 with the locking column 36, the guiding inclined surface 32 can ensure that the locking column 36 slides into the sliding arc groove 31 more smoothly, thereby ensuring the normal operation of the device.

[0057] The working principle of this device is: during the actual installation, the staff directly brings the folded inner partition wall to the construction site, and then unfolds it to form a complete inner partition wall skeleton (refer to the unfolding process Figure 2 , Figure 3), wait for the inner partition wall to be fully unfolded, and then fix the inner partition wall frame with fixing bolts (it should be noted that both the top frame 1 and the bottom frame 8 are provided with fixing bolts, which is a mature existing technology and will not be described in detail here), and then install sound insulation foam and wall panels on the unfolded inner partition wall frame. This foldable inner partition wall frame greatly shortens the construction time, and makes the frame that originally needs to be assembled one by one become modular assembly, thereby improving work efficiency. In the process of unfolding the inner partition wall frame, first unfold the two hinged bottom frames 8 and the top frame 1 (such as Figure 2 ), and then unfold the top frame 1 hinged on the bottom frame 8 (such as Figure 3 ), during this process, the load-bearing vertical keel 10 on the top frame 1 drives the limit support plate 35 to move, and the movement of the limit support plate 35 drives the locking column 36 to slide into the sliding arc groove 31, and the toggle block 41 contacts the contact convex plate 27, thereby driving the sliding plate 23 to move downward along the sliding vertical groove 28, and then the sliding plate 23 drives the connecting chuck 25 and the rotating sleeve 24 to move downward. At this time, the return spring 26 is compressed, and the adapter chuck 2 continues to flip along with the connecting rod 11 in the top frame 1, and the connecting chuck 25 is in Driven by the sliding plate 23, it moves downward to avoid the adapter chuck 2, waiting for the top extending inclined block 42 to contact the contact protrusion 29, and the telescopic block 39 to retract into the supporting block 38, thereby driving the toggle block 41 to separate from the contact protrusion 27, and then the sliding plate 23 is no longer under pressure, and then the reset spring 26 is reset, thereby driving the sliding plate 23 to move up and reset, and driving the connecting chuck 25 to move upward and clamp together with the adapter chuck 2, so that the connecting rod 11 on the top frame 1 is connected with the connecting rod 11 in the bottom frame 8. When the inner partition wall needs to be extended laterally, the worker manually rubs the toggle wheel 12 to rotate, and the rotation of the toggle wheel 12 drives the connecting rod 11 to rotate, and the rotation of the connecting rod 11 drives the worm 13 to rotate, and the rotation of the worm 13 drives the worm wheel 22 to rotate, and the rotation of the worm wheel 22 drives the threaded rod 21 to rotate. The rotation of the threaded rod 21 causes the threaded tube 7 to move in the axial direction of the threaded rod 21 through the action of the thread, and then the threaded tube 7 drives the movable keel 4 to move, so as to realize the lateral extension and contraction of the inner partition wall frame, ensuring that the entire inner partition wall frame can adapt to a variety of construction environments.

[0058] When the entire inner partition wall frame needs to be folded and disassembled, the unlocking strip 33 is pressed, and the unlocking strip 33 touches the locking column 36, so that the locking column 36 is squeezed out from the locking hole 34, and then the inner partition wall frame can be smoothly folded. In this way, the entire inner partition wall frame can be reused, achieving the purpose of energy saving and environmental protection, and also saving construction costs to a certain extent.

[0059] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
