Description

Technical Field

[0001] This utility model belongs to the field of building construction safety technology, and in particular relates to a safety fixing device for preventing collapse during building construction. Background Technology

[0002] Safety protection panels are used in building construction, and fixing devices are needed when installing them. A search of Chinese Patent Publication No. CN222253485U reveals a quick-fixing device for safety protection panels in building construction. This device includes a rectangular fixing box and a safety protection panel. The rectangular fixing box is hollow inside, with a first rectangular groove communicating with its front surface and a second rectangular groove communicating with its right side. This quick-fixing device uses a bidirectional threaded rod as a driving mechanism, in conjunction with two sliding sleeves and two second sliders, to fix the safety protection panel by moving the vertical positions of two concave fixing plates. Compared to using threaded fixing, it eliminates the need for individual bolt fixing with external tools, offering advantages such as ease of use and rapid installation. Under the action of springs, the corresponding upper and lower fixing plates are tightly fitted to the outer surface of the safety protection panel, preventing lateral swaying and further improving the stability of the safety protection panel.

[0003] However, in the above-mentioned solution, the safety protection plate is clamped and fixed by the concave fixing plate and the fixing clamp, and the angle is completely fixed. It is impossible to adjust the protection angle according to the construction scenario (such as the slope of the foundation pit, the corner of the staircase, etc.). It can only be used for planar protection, and its applicability is limited. Therefore, it is necessary to design a collapse prevention safety fixing device for building construction. Utility Model Content

[0004] This utility model provides a safety fixing device for preventing collapse during building construction, aiming to solve the problem that existing technologies cannot adjust the protective angle according to the construction scenario and can only be used for planar protection, thus limiting their applicability.

[0005] This utility model is implemented as follows: a safety fixing device for preventing collapse during building construction, comprising two protective plates, and further comprising: The mounting column has arc-shaped grooves on its top and bottom sides, and elastic pads are fixedly embedded in the arc-shaped grooves. The edge of the protective plate is fixed with mounting blocks corresponding to the arc-shaped grooves. Two locking components are arranged symmetrically above and below each other and can slide vertically relative to the mounting post; An actuator, located in the middle of the mounting column, is used to drive two locking components to lock the mounting block synchronously. When locked, the mounting block can compress the elastic pad and rotate within the arc-shaped groove.

[0006] Preferably, the mounting block has a positioning hole, and the bottom of the positioning hole has an inclined groove that is biased towards the mounting column.

[0007] Preferably, the mounting post includes: The frame is a frame-like structure welded from multiple steel plates; Flat-headed steel columns, which are welded and fixed to the top of the frame; A pointed insert rod is welded and fixed to the bottom of the frame and axially aligned with the flat-headed steel column, with the pointed end of the rod facing downwards.

[0008] Preferably, the mounting post further includes a threaded rod, which is rotatably connected to the frame. The two ends of the threaded rod are provided with external threads in opposite directions, and a second bevel gear is coaxially fixed at the middle position of the threaded rod.

[0009] Preferably, the actuator includes: A bracket, which is welded and fixed to the outer side of the frame; A rotating shaft passes through the bracket and is rotatably connected to the bracket; The first bevel gear is fixed to one end of the rotating shaft and meshes with the second bevel gear; A handle, which is fixed to the other end of the rotating shaft.

[0010] Preferably, the locking component includes: The U-shaped slider has its sliding limit located inside the frame and engages with the external thread; Two screws, which pass through the U-shaped slider from bottom to top; Two nail heads are fitted over the screw from top to bottom and engage with the screw threads.

[0011] Preferably, the top of the nail head is chamfered so that it can be slidably inserted into the positioning hole via the beveled groove.

[0012] Compared with related technologies, the anti-collapse safety fixing device for building construction provided by this utility model has the following beneficial effects: 1. This utility model sets arc-shaped grooves on both sides of the top and bottom of the mounting column, embeds elastic pads in the grooves, and fixes mounting blocks that match the arc-shaped grooves on the edge of the protective plate. After the mounting blocks are inserted into the arc-shaped grooves, they can rotate along the arc surface of the arc-shaped grooves, thereby driving the protective plate to adjust the angle, meet the protection requirements of different slopes and corners, realize the free adjustment of the protective plate at multiple angles, and can stably maintain the angle after adjustment, adapting to complex construction environments; 2. This utility model embeds an elastic pad in the arc groove. On the one hand, when the mounting block is locked, the elastic pad is squeezed, and the friction generated by the elastic deformation forms a damping positioning on the protective plate, so that the protective plate is stably maintained at the adjusted angle and avoids self-rotation, so as to facilitate the series splicing installation with other protective plates. On the other hand, the elastic pad can buffer the force of the protective plate when it is subjected to external impact, and improve the safety of preventing collapse. 3. This utility model provides a positioning hole on the mounting block and an inclined groove at the bottom that is biased towards the mounting column. The nail head of the locking component is chamfered and can slide into the positioning hole along the inclined groove. This achieves rapid positioning of the mounting block without affecting the rotation and adjustment of the mounting block in the arc groove. It balances positioning accuracy and angular flexibility, reduces error, and improves installation convenience. Attached Figure Description

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0016] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] A preferred embodiment provided by this utility model is, for example... Figures 1 to 6 As shown: A safety fixing device for preventing collapse in building construction includes two protective plates 1, as well as mounting columns 2, two locking components 5, and an actuator 4. The mounting columns 2 have arc-shaped grooves 211 on the top and bottom sides, and elastic pads are fixedly embedded in the arc-shaped grooves 211. The elastic pads have two functions: firstly, when the mounting blocks 3 are locked, they squeeze the elastic pads, and the friction generated by the elastic deformation forms a damping positioning on the protective plates, so that the protective plates 1 are stably maintained at the adjusted angle and prevent them from rotating on their own, so as to facilitate the series splicing installation with other protective plates 1; secondly, the elastic pads can buffer the force of the protective plates 1 when they are subjected to external impact, thereby improving the safety of preventing collapse.

[0018] Unlike existing devices, in this invention, the protective plate 1 has a mounting block 3 fixed to its edge, corresponding to the arc groove 211; two locking components 5 are symmetrically arranged vertically and can slide vertically relative to the mounting column 2; the actuator 4 is located in the middle of the mounting column 2 and is used to drive the two locking components 5 to lock the mounting block 3 synchronously. When the mounting block 3 is locked, it can squeeze the elastic pad and rotate within the arc groove 211. After the mounting block 3 is inserted into the arc groove 211, it can rotate along the arc surface of the arc groove 211, thereby driving the protective plate 1 to adjust its angle (such as within the range of 0°-90°), meeting the protection requirements of different slopes and corners, realizing the free adjustment of the protective plate 1 at multiple angles, and maintaining the angle stably after adjustment, adapting to complex construction environments.

[0019] It should be noted that the mounting column 2 includes a frame 21, a flat-headed steel column 22, a pointed insertion rod 23, and a threaded rod 24. The frame 21 is a frame structure welded from multiple steel plates. The flat-headed steel column 22 is welded and fixed to the top of the frame 21. The flat-headed steel column 22 can withstand the hammering action, and its structural rigidity ensures that it will not deform due to repeated hammering. The pointed insertion rod 23 is welded and fixed to the bottom of the frame 21 and is axially aligned with the flat-headed steel column 22. The pointed end of the pointed insertion rod 23 faces downward and is used to insert into the foundation under the action of hammering.

[0020] Existing devices use a bidirectional threaded rod to drive two concave fixing plates to move relative to each other and clamp the protective plate. However, this requires manual assistance to hold the protective plate until it is clamped, demanding high coordination skills. Furthermore, the fixing plates rely on springs for elastic clamping, which are prone to fatigue over time, leading to a decrease in clamping force. In contrast, this invention uses an arc-shaped groove 211 to pre-lock the mounting block 3, and a synchronous actuator 4 drives the upper and lower locking components 5 to move synchronously, achieving automatic positioning and clamping of the mounting block 3 without manual assistance. This results in a stable and durable locking force and stronger resistance to loosening.

[0021] Furthermore, the threaded rod 24 is rotatably connected to the frame 21. The two ends of the threaded rod 24 are provided with external threads 25 in opposite directions. The second bevel gear 26 is coaxially fixed at the middle position of the threaded rod 24. The actuator 4 includes a bracket 41, a rotating shaft 42, a first bevel gear 43, and a handle 44. The bracket 41 is welded and fixed to the outer side of the frame 21. The rotating shaft 42 passes through the bracket 41 and is rotatably connected to the bracket 41. The first bevel gear 43 is fixed to one end of the rotating shaft 42 and meshes with the second bevel gear 26. The handle 44 is fixed to the other end of the rotating shaft 42. When the handle 44 is rotated, the rotating shaft 42 drives the first bevel gear 43 to rotate, thereby driving the second bevel gear 26 and the threaded rod 24 to rotate.

[0022] Furthermore, the locking component 5 includes a U-shaped slider 51, two screws 52, and two nail heads 53. The sliding limit of the U-shaped slider 51 is located inside the frame 21 and engages with the external thread 25. The two screws 52 pass through the U-shaped slider 51 from bottom to top, and the two nail heads 53 are sleeved on the outside of the screws 52 from top to bottom and engage with the screws 52 threadedly. When the threaded rod 24 rotates, the two U-shaped sliders 51 move synchronously relative to each other vertically along the frame 21 (one upward and one downward), causing the screws 52 and nail heads 53 to move synchronously closer to the mounting block 3, thereby achieving synchronous locking of the upper and lower mounting blocks 3 without the need for step-by-step operation, and the locking force is uniform.

[0023] Furthermore, the mounting block 3 is provided with a positioning hole 31. The bottom of the positioning hole 31 is provided with a sloping groove 32 that is inclined to one side of the mounting post 2. The top of the nail head 53 is chamfered and can be slidably inserted into the positioning hole 31 through the sloping groove 32. It can slide into the positioning hole 31 along the sloping groove 32, which not only realizes the rapid positioning of the mounting block 3, but also does not affect the rotation adjustment of the mounting block 3 in the arc groove 211, thus taking into account both positioning accuracy and angular flexibility.

[0024] During assembly, the mounting blocks 3 on the sides of the two protective plates 1 are pre-inserted into the arc-shaped grooves 211 at both ends of the mounting column 2. The handle 44 drives the rotating shaft 42 to rotate, and the meshing of the first bevel gear 43 and the second bevel gear 26 drives the threaded rod 24 to rotate. Through the threaded engagement of the external threads 25 at both ends of the threaded rod 24 with the upper and lower U-shaped sliders 51, and the sliding limit of the frame 21 on the U-shaped sliders 51, the two U-shaped sliders 51 can be driven to move vertically relative to each other. This allows the screws 52 on the two U-shaped sliders 51 to be gradually guided from the inclined groove 32 into the positioning hole 31 until the mounting block 3 is locked in the arc-shaped groove 211 and squeezes the elastic pad. The two protective plates 1 can rotate in the arc-shaped groove 211 through the mounting block 3 to adjust the protection angle, and the elastic pad dampens the rotation of the protective plates 1, keeping the protective plates 1 at a certain angle so as to complete the series splicing installation with other protective plates 1.
