[0002] In recent years, with the vigorous development of building industrialization, the prefabricated building market has flourished, and new prefabricated systems are constantly emerging. SPCS prefabricated wall panels are a modern building material made of prefabricated panels and cement mixtures. After the prefabricated wall panels are hoisted onto a platform and temporarily supported, there is a 50mm gap between the base of the wall and the structural floor. L-shaped baffles are installed on the inner side of the wall, and vertical baffles are installed on the outer side of the wall to cover the gap and fix the vertical and L-shaped baffles to facilitate subsequent concrete pouring and other work.

[0003] Currently, one existing fixing mechanism includes a screw, a first nut, and a second nut. One end of the screw passes through the first nut, an L-shaped baffle, a vertical baffle, and the second nut in sequence and is screwed together. The first nut and the second nut fix the vertical baffle and the L-shaped baffle to both sides of the wall.

[0004] However, the aforementioned fixed mechanism requires personnel to operate it from the outside of the wall, resulting in poor ease of operation and low efficiency. Utility Model Content

[0005] (a) The problem to be solved by this utility model is that traditional fixing mechanisms require personnel to operate from outside the wall, which is inconvenient and inefficient.

[0006] (II) Technical Solution The present invention provides a fixing mechanism for fixing an L-shaped baffle and a vertical baffle to both sides of a precast wall panel, including a first fixing component, the first fixing component including a first round rod, a first nut, a first limiting structure and a first connecting structure; One end of the first round rod is screwed to the first nut, and the other end of the rod is provided with a first opening structure that is adapted to the first limiting structure; The first connecting structure is connected to one side of the vertical baffle. The first connecting structure includes a first rotating shaft, and the first limiting structure can rotate around the axis of the first rotating shaft.

[0007] According to one embodiment of the present invention, the first connecting structure includes a first fixing block, and the first limiting structure includes a first limiting block and a first connecting rod connected to each other. One end of the first connecting rod is rotatably connected to the first fixed block via the first rotating shaft, and the other end is fixedly connected to the first limiting block.

[0008] According to one embodiment of the present invention, the distance from the first rotating shaft to the first round rod is less than the length of the first limiting structure.

[0009] According to one embodiment of the present invention, the first limiting block has opposing abutting surfaces and arc surfaces; The contact surface is located on the side of the arc surface away from the first nut.

[0010] According to one embodiment of the present invention, a first spring is connected between the first connecting rod and the vertical baffle.

[0011] According to one embodiment of the present invention, the fixing mechanism further includes a second fixing component, the second fixing component including a second connecting structure, a second round rod, a second nut and a second limiting structure; One end of the second round rod is screwed with the second nut, and the other end is provided with a second opening structure that is compatible with the second limiting structure; The second connecting structure includes a second fixing block, and the second limiting structure includes a second connecting rod and a second limiting block connected to each other. The second fixing block has a sliding hole, and the second connecting rod is slidably connected in the sliding hole.

[0012] According to one embodiment of the present invention, the second opening structure is a scalloped groove, and the depth of the scalloped groove on the side near the second nut is less than the depth on the other side.

[0013] According to one embodiment of the present invention, the second connecting structure further includes a second spring and a connecting plate; One end of the second spring is connected to the connecting plate, and the other end is connected to the second connecting rod; The connecting plate is connected to the vertical baffle.

[0016] The beneficial effects of this utility model are: One end of the first round rod passes through the L-shaped baffle, the sleeve, and the vertical baffle in sequence along the first direction. When the first opening structure passes the first limiting structure, the first limiting structure enters the first opening structure and is pulled in the opposite direction, so that one side of the first limiting structure abuts against the side wall of the first opening structure away from the first nut. At this time, the first limiting structure restricts the first round rod from moving along the second direction. The first nut is screwed on the first round rod to bring it close to the first limiting structure until the first nut can no longer be screwed.

Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1-6 As shown, one embodiment of the present invention provides a fixing mechanism for fixing an L-shaped baffle 9 and a vertical baffle 10 to both sides of a precast wall panel, including a first fixing component, which includes a first round rod 1, a first nut 2, a first limiting structure 3 and a first connecting structure 4; One end of the first round rod 1 is screwed to the first nut 2, and the other end is provided with a first opening structure 11 that is adapted to the first limiting structure 3; The first connecting structure 4 is connected to one side of the vertical baffle 10. The first connecting structure 4 includes a first rotating shaft 41, and the first limiting structure 3 can rotate around the axis of the first rotating shaft 41.

[0022] It should be noted that the end of the first round rod 1 away from the first opening structure 11 has a thread.

[0023] In actual use, first place the L-shaped baffle 9 on the inside of the precast wall panel, and then hoist the vertical baffle 10 to the outside of the precast wall panel. One end of the first round rod 1 passes through the L-shaped baffle 9, the sleeve 13, and the vertical baffle 10 in sequence along the first direction. When the first opening structure 11 passes the first limiting structure 3, the first limiting structure 3 enters the first opening structure 11 and is pulled in the opposite direction, so that one side of the first limiting structure 3 abuts against the side wall of the first opening structure 11 away from the first nut 2. At this time, the first limiting structure 3 restricts the first round rod 1 from moving along the second direction. The first nut 2 is screwed on the first round rod 1 to bring it close to the first limiting structure 3 until the first nut 2 can no longer be screwed. The L-shaped baffle 9 and the vertical baffle 10 can then be fixed to both sides of the outer wall formwork. The fixing method is simple and only needs to be operated on the inner platform of the precast wall. It is convenient and efficient.

[0024] The fixing mechanism also includes multiple sleeves 13, with a sleeve 13 fitted on each of the first round rod 1 and the second round rod 6, and each sleeve 13 is located between the vertical baffle 10 and the L-shaped baffle 9.

[0025] After the L-shaped baffle 9 and the vertical baffle 10 are fixed in place, it is convenient for subsequent concrete pouring. If it is necessary to remove the first round rod 1, the first nut 2 can be unscrewed. Since the first round rod 1 is fitted with a sleeve 13, after the concrete pouring is completed, the sleeve 13 is fixed to the concrete. However, the first round rod 1 located in the corresponding sleeve 13 can still move a distance along the first direction so that the first limiting block 31 exits the first opening structure 11. Then, rotate the first round rod 1 to remove the first round rod 1.

[0026] The first direction and the second direction are two opposite directions.

[0027] It should be noted that the first limiting structure 3 and the first connecting structure 4 are both located on the side of the vertical baffle 10 away from the L-shaped baffle 9, and the other side of the vertical baffle 10 is tightly attached to the outer wall of the precast wall panel.

[0028] like Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the first connecting structure 4 includes a first fixing block 42, and the first limiting structure 3 includes a first limiting block 31 and a first connecting rod 32 connected to each other. One end of the first connecting rod 32 is rotatably connected to the first fixed block 42 via the first rotating shaft 41, and the other end is fixedly connected to the first limiting block 31. Specifically, the first fixed block 42 has a groove, and the first rotating shaft 41 is connected inside the groove. The first connecting rod 32 has a shaft hole, and the first rotating shaft 41 is rotatably connected inside the shaft hole. The depth direction of the groove and the width direction of the first connecting rod 32 are the same as the axial direction of the first round rod 1. The depth of the groove is greater than the width of the first connecting rod 32, so as not to affect the rotation of the first connecting rod 32 around the first rotating shaft 41.

[0029] According to one embodiment of the present invention, the distance from the first rotating shaft 41 to the first round rod 1 is less than the length of the first limiting structure 3, so that the first limiting structure 3 can rotate around the first rotating shaft 41 and enter the first opening structure 11.

[0030] According to one embodiment of the present invention, the first limiting block 31 has a contact surface and an arc surface, with the contact surface located on the side of the arc surface away from the first nut 2. The contact surface is preferably a plane, capable of contacting the side wall of the first opening structure 11. By being set as an arc surface, it facilitates the first limiting block 31's exit from the first opening structure 11. The direction from the contact surface to the arc surface is denoted as the length direction of the first limiting block 31. The length directions of both the first opening structure 11 and the first limiting block 31 are the same as the length direction of the first round rod 1. The length of the first opening structure 11 is greater than the length of the first limiting block 31, facilitating the first limiting block 31's rotation into or out of the first opening structure 11.

[0031] It should be noted that when the first limiting block 31 enters the first opening structure 11 and pulls the first round rod 1 along the second direction, the abutting surface of the first limiting block 31 abuts against the side wall of the first opening structure 11 when it can no longer be pulled. Preferably, at this time, the arc surface of the first limiting block 31 abuts against the vertical baffle 10. Optionally, a limiting plate is connected to the side of the first connecting rod 32 near the vertical baffle 10, and the side of the limiting plate away from the first connecting rod 32 abuts against the vertical baffle 10. This does not depart from the design concept of this utility model, therefore, it should fall within the protection scope of this utility model.

[0032] According to one embodiment of the present invention, a first spring 43 is connected between the first connecting rod 32 and the vertical baffle 10.

[0033] It should be noted that when the first spring 43 is provided, the first connecting rod 32 can be located at any position on the upper or lower or left and right sides of the first round rod 1. The elastic force of the first spring 43 can drive the first limiting block 31 into the first opening structure 11. When the first spring 43 is not provided, the first connecting structure 4 is located on the upper side of the first limiting structure 3, and the first connecting rod 32 can only be located on the upper side of the first round rod 1. The first limiting block 31 enters the first opening structure 11 by gravity.

[0034] Taking the first connecting rod 32 located on the upper side of the first round rod 1 and having a first spring 43 as an example, when the first round rod 1 moves along the first direction (i.e., from the L-shaped baffle 9 to the vertical baffle 10), the first limiting block 31 is first pushed open, the first limiting block 31 rotates around the first rotating shaft 41, the first spring 43 is stretched, and the lower end face of the first limiting block 31 abuts against the side wall of the first round rod 1. When the first opening structure 11 passes the lower end face of the first limiting block 31, under the action of the elastic force of the first spring 43 and gravity, the first limiting block 31 enters the first opening structure 11. At this time, the first round rod 1 is pulled along the second direction, so that the side wall of the first limiting block 31 and the side wall of the first opening structure 11 abut away from the second nut 7, which can restrict the first round rod 1 from continuing to move along the second direction.

[0035] It should be noted that the first nut 2 is configured to restrict the movement of the first round rod 1 in the first direction.

[0036] Preferably, the first round rod 1 and the second round rod 6 have threads on only one end, and the other end is a smooth plane.

[0037] The first opening structure 11 can be a groove, a hole, or a through channel. Its purpose has not departed from the design concept of this utility model, and therefore, it should fall within the protection scope of this utility model.

[0038] According to one embodiment of this utility model, an indicator arrow 12 is provided at one end of the first round rod 1 near the first nut 2. The position of the first opening structure 11 can be identified by the indicator arrow 12, so that the first limiting block 31 can smoothly enter the first opening structure 11. Of course, the direction of the first opening structure 11 can also be indicated by a label or a groove on the end of the first round rod 1.

[0039] According to one embodiment of the present invention, the fixing mechanism further includes a second fixing component, which includes a second connecting structure 5, a second round rod 6, a second nut 7, and a second limiting structure 8. One end of the second round rod 6 is screwed with a second nut 7, and the other end is provided with a second opening structure 61 that is compatible with the second limiting structure 8. The second connecting structure 5 includes a second fixing block 51, and the second limiting structure 8 includes a second connecting rod 82 and a second limiting block 81 connected to each other. The second fixing block 51 has a sliding hole, and the second connecting rod 82 is slidably connected in the sliding hole.

[0040] Preferably, the second connecting rod 82 is a T-shaped rod, which includes a first rod body and a second rod body. The width of the first rod body is greater than the width of the second rod body. The second rod body slides in the sliding hole, and the first rod body cannot pass through the sliding hole. The second rod body is located on the side of the second fixing block 51 away from the second limiting block 81, thereby limiting the depth of the second limiting block 81 entering the second opening structure 61.

[0041] It should be noted that the second limiting block 81 is a slab-shaped block. The side of the slab-shaped block closest to the second nut 7 is an inclined surface. The inclined surface forms an angle with the axis of the second round rod 6, and the angle is an acute angle.

[0042] When the second spring 53 is in its original state, the spur block protrudes from the second round rod 6 (that is, when the second connecting structure 5 is located on the upper side of the second round rod 6, the upper surface of the spur block is higher than the second round rod 6).

[0043] According to one embodiment of the present invention, the second opening structure 61 is a swivel-shaped groove, and the depth of the swivel-shaped groove on the side near the second nut 7 is less than the depth on the other side. The swivel-shaped groove can assist the second limiting block 81 in exiting the second opening structure 61.

[0044] According to one embodiment of the present invention, the second connecting structure 5 further includes a second spring 53 and a connecting plate 52; One end of the second spring 53 is connected to the connecting plate 52, and the other end is connected to the second connecting rod 82; Both the connecting plate 52 and the second fixing block 51 are connected to the vertical baffle 10.

[0045] The second connecting structure 5 is set on the upper side of the second round rod 6. After the second round rod 6 passes through the L-shaped baffle 9, a sleeve 13 and a vertical baffle 10 along the first direction, the second round rod 6 abuts against the inclined surface of the second limiting block 81 so that the second limiting block 81 moves vertically upward. The second spring 53 is compressed, and the lower end of the second limiting block 81 abuts against the end face of the second round rod 6. When the second opening structure 61 passes by, the second limiting block 81 enters the second opening structure 61 under the action of the second spring 53, and pulls the second round rod 6 in the opposite direction so that the vertical surface of the second limiting block 81 abuts against the side wall of the second opening structure 61 away from the second nut 7. Then, the second nut 7 is screwed closer to the second limiting block 81 to fix the L-shaped baffle 9 and the vertical baffle 10 to the inner and outer sides of the precast wall panel respectively. At this time, the two ends of the sleeve 13 abut against the L-shaped baffle 9 and the vertical baffle 10 respectively, which facilitates the subsequent concrete pouring work. When it is necessary to remove the second round rod 6, remove the second nut 7. Since the second round rod 6 is fitted with a sleeve 13, after the concrete pouring work is completed, the sleeve 13 is fixed to the concrete. However, the second round rod 6 located in the corresponding sleeve 13 can still move a distance in the first direction so that the second limiting block 81 exits the second opening structure 61. Rotate the second nut 7 to remove the second round rod 6.

[0046] It should be noted that, since there is a gap of about 50mm between the base of the wall and the structural floor, and the diameter of the sleeve 13 is smaller than this gap, the sleeve 13 can be smoothly placed between the vertical baffle 10 and the L-shaped baffle 9.

[0047] The length direction of the sleeve 13 is the same as the thickness direction of the precast wall panel, and the length of the sleeve 13 is slightly greater than the thickness of the precast wall panel. Preferably, the two ends of the sleeve 13 are connected to annular sealing rings.

[0048] To prevent the gaps between the L-shaped baffle 9 and the vertical baffle 10 and the inner and outer sides of the precast wall panel from overflowing, sealing strips are usually installed on the sides of the L-shaped baffle 9 and the vertical baffle 10 that are close to each other. When the two ends of the sleeve 13 abut against the L-shaped baffle 9 and the vertical baffle 10 respectively, the sealing strips are squeezed to seal the gaps.

[0049] Furthermore, the second connecting structure 5 also includes a first ring and a second ring coaxially sleeved together. The first ring is connected to the second fixing block 51, and the second ring is connected to the connecting plate 52. A second spring 53 is sleeved inside the first ring to limit the extension and retraction direction of the second spring 53. The length direction of the second spring 53 is the same as the sliding direction of the second connecting rod 82.

[0050] The length direction of the first round rod 1 is the same as that of the second round rod 6.
