Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to an adjustable edge protection fixing structure for building construction. Background Technology

[0002] During construction, edge protection structures play a crucial role as essential facilities for ensuring the personal safety of construction workers. In existing technologies, edge protection structures typically consist of columns, crossbars, and protective panels. The columns are often fixed by anchor bolts to the ground or by pre-casting cement blocks to embed the columns in the ground, thereby providing support for the protective panels.

[0003] However, these traditional fixing methods have significant shortcomings. First, when the columns are fixed with anchor bolts, once installed, angle adjustment is difficult, lacking flexibility and making it hard to adapt to complex and changing construction site environments. Second, using cement blocks for pre-embedded fixing not only results in a long construction period but also suffers from low overall installation efficiency due to curing time constraints, affecting the construction progress. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable edge protection fixing structure for building construction, which facilitates the adjustment of the angle of the protective plate and the overall installation and fixing, and effectively improves the installation efficiency.

[0005] This utility model is achieved through the following technical solution: An adjustable edge protection fixing structure for building construction includes: The base plate has multiple anchor bars fixedly installed at its bottom. An inverted U-shaped rod is fixedly installed on one side of the top wall of the base plate, and a pair of clips is fixedly installed on the other side. The top wall of the side where the clips are close to each other is provided with a hook. A fixing rod, one end of which has an inclined groove for slidingly engaging with the U-shaped rod, has a rounded corner on one side of the inclined groove and near the bottom plate, the rod body of which is used to engage with a pair of clips, and the hook is hooked onto the top wall of the fixing rod; A swing rod is hinged to the end of the fixed rod away from the inclined groove. The swing rod has a slot along its length for the insertion strip on the back of the protective plate to slide and engage. The insertion strip is fixed to the slot by bolts. A diagonal brace is hinged between the swing rod and the fixed rod. The diagonal brace is telescopic and has a fixing member on it for fixing the diagonal brace to the telescopic position.

[0006] Furthermore, a deformable rubber block is embedded in the bottom wall of the fixing rod, and the deformable rubber block initially protrudes from the side of the fixing rod near the bottom plate.

[0007] Furthermore, the diagonal brace includes a first rod body and a second rod body. The first rod body is slidably sleeved on the first rod body to form a telescopic structure. The fixing member includes a locking screw, which is threaded through the first rod body. The second rod body has a plurality of through holes along its length for the locking screw to pass through.

[0008] Furthermore, a long groove is provided on the side of the fixing rod away from the inclined groove, a stud is fixedly provided vertically along the bottom plate, a limit block is slidably inserted in the long groove, the limit block has a protrusion that abuts against the top wall of the fixing rod, and a nut that abuts against the protrusion is threaded onto the stud.

[0009] Furthermore, an arc-shaped spring is provided between the first rod and the fixed rod, with one end of the arc-shaped spring fixedly connected to the first rod and the other end fixedly connected to the fixed rod.

[0010] Furthermore, a pair of arc-shaped spring pieces are provided, and the arc-shaped arched surfaces of the pair of arc-shaped spring pieces are arranged opposite to each other.

[0011] Furthermore, the anchor strip is sheet-shaped, and its thickness gradually decreases along the side away from the base plate, while the width of the anchor strip gradually decreases along the side away from the base plate.

[0012] Furthermore, the anchor bar is hollow, and multiple grouting holes are provided on the peripheral wall of the anchor bar. An opening communicating with the hollow cavity of the anchor bar is provided on the bottom plate.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects: 1. This utility model uses a base plate to support the weight of the edge protection structure as a whole, and multiple anchors at the bottom are inserted into the ground to form a stable connection to the ground, thereby effectively enhancing the stability and anti-overturning ability of the structure and ensuring safety during use.

[0014] Secondly, by setting an inverted U-shaped rod on one side of the top wall of the base plate, and having a groove structure at one end of the fixing rod to cooperate with it, the fixing rod can be inserted obliquely into the U-shaped rod to form a limiting fit. This structure not only effectively prevents the fixing rod from accidentally falling off during use, but also, together with the rounded corner design at one end, makes the insertion operation of the fixing rod smoother, improving the convenience and adaptability of rapid on-site installation.

[0015] In addition, the fixed rod body can be snapped between a pair of clips with hooks on the base plate, further strengthening the multi-point stable connection between the fixed rod and the base plate. The overall structure can be assembled efficiently without bolt fixation, greatly improving the assembly and disassembly efficiency on the construction site.

[0016] Furthermore, the far end of the fixed rod is connected to the swing rod via a hinge, enabling the swing rod to adjust its angle relative to the fixed rod. This allows the angle of the swing rod to be adjusted according to the construction requirements of different slopes or edge angles on site, ensuring the stability of the protective plate under various tilt conditions. The diagonal brace, hinged to the fixed rod and swing rod, utilizes its own extensibility and the locking function of the fasteners to provide rigid support and precise positioning for the swing angle, ensuring the protective plate remains stable at the required angle and improving the adaptability and reliability of edge protection. Finally, by setting a plug slot on the swing arm and using a plug and bolt structure, the protective plate can be quickly slid into position and firmly fixed, improving on-site operation efficiency.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example

[0020] The following is for reference Figures 1-4 As shown in the figure, and further illustrated by a specific embodiment, this embodiment provides an adjustable edge protection fixing structure for building construction. This structure can achieve rapid positioning, angle adjustment, and stable support of the protective plate, and is suitable for safety protection in edge work areas.

[0021] like Figure 1 and Figure 2 As shown, the edge protection fixing structure includes a base plate 1. Four anchor bars 11 are fixedly welded to the bottom of the base plate 1, and the anchor bars 11 are evenly distributed at the four corners of the base plate 1 to achieve stable anchoring of the structure. An inverted U-shaped rod 12 is welded to one side of the top wall of the base plate 1, and a pair of clips 13 are welded to the other side. Hooks 131 are provided on the top wall of the side where the two clips 13 are close to each other, for cooperating with the fixing rod 2 for limiting the position. In actual installation, multiple pairs of clips 13 can be set according to the size of the protective plate 4 and the requirements of the working area to enhance the load-bearing and locking capacity of the structure.

[0022] One end of the fixing rod 2 has a slanted groove 21 for slidingly engaging with the U-shaped rod 12. To facilitate insertion and avoid interference, the fixing rod 2 has a rounded corner 22 on the side near the slanted groove 21, allowing the operator to quickly insert it obliquely into the U-shaped rod 12 and gradually conform it downwards to the base plate 1 to form a limiting fit and prevent it from falling off. The rod body of the fixing rod 2 is inserted between a pair of clips 13 and hooked onto the top wall of the fixing rod 2 via hooks 131, forming a multi-point stable connection structure, which effectively improves the overall installation efficiency and reliability. It should be noted that due to the presence of the slanted groove 21, the fixing rod 2 cannot move along its length after being fixedly attached to the base plate 1; a fixed fit is formed after it is engaged with the clips 13.

[0023] The end of the fixed rod 2 away from the inclined groove 21 is connected to the swing rod 3 by a hinge, facilitating swing adjustment. The swing rod 3 has an insertion groove 31 along its length for slidingly installing the insert 41 on the back of the protective plate 4. The insert 41 can be an anti-detachment structure (e.g., T-shaped, dovetail-shaped) to enhance locking performance after insertion. In this embodiment, the insertion groove 31 has a cross-section with a wide arc-shaped bottom wall and an opening 15 on the outer side that is narrower than the bottom wall, combining smooth insertion with pull-out resistance. After installation, the insert 41 is fixed with bolts 42 to ensure its stability during long-term use. Furthermore, to improve the overall structural strength of the protective plate 4, multiple reinforcing crossbars or a closed frame structure can be welded to the back of the protective plate 4 to prevent deformation or loosening of the plate.

[0024] like Figure 2 and Figure 3 As shown, to achieve adjustment of the protective angle and support stability, a diagonal brace 5 is provided between the swing rod 3 and the fixed rod 2. The diagonal brace 5 is a telescopic structure, including a first rod body 51 and a second rod body 52. ​​The first rod body 51 is slidably sleeved on the second rod body 52 for easy length adjustment. A fixing member 6 for locking its length is provided on the diagonal brace 5. In this embodiment, it is a locking screw 61 threaded through the first rod body 51. The second rod body 52 has multiple through holes 521 evenly distributed along its length. The operator can insert the screw into the through holes 521 at different positions to achieve length limitation, thereby adjusting the installation angle of the protective plate 4 to adapt to different construction slopes or platform height differences. In other embodiments, the fixing member 6 can also be a connecting structure such as a pin.

[0025] To further secure the fixing rod 2, an elongated groove 24 is formed on the side of the fixing rod 2 away from the inclined groove 21. A stud 14 is vertically welded to the corresponding position on the base plate 1, and a nut 26 is threaded onto the stud 14. A limiting block 25 is slidably installed in the elongated groove 24. The limiting block 25 is conical and has a protruding edge 251 that abuts against the top wall of the fixing rod 2. When the nut 26 presses against the protruding edge 251, the fixing rod 2 can be further locked, effectively preventing it from shaking under wind load or construction disturbance.

[0026] To buffer stress transmission between components in the support structure and improve the system's flexibility and resilience, a pair of arc-shaped spring pieces 7 are installed between the first rod 51 and the fixed rod 2. The two arc-shaped spring pieces 7 are positioned opposite each other, with one end fixedly connected to the first rod 51 and the other end connected to the fixed rod 2. The arc-shaped spring pieces 7 are made of elastic metal material and can undergo slight deformation under stress, thereby enhancing the structure's adaptability to impact loads or minor vibrations while maintaining a triangular support relationship.

[0027] Furthermore, such as Figure 3As shown, a deformable rubber block 23 is embedded in the bottom wall of the fixing rod 2. The rubber block is located below the fixing rod 2 near the base plate 1, and in the initial state, it partially protrudes from the bottom surface of the fixing rod 2. The rubber block is made of rubber material with excellent resilience (such as EPDM, TPR, etc.). Its purpose is to provide a certain upward support force so that the fixing rod 2 can be actively pressed and form a tight fit when it is inserted between the U-shaped rod 12 and the clamp 13 of the base plate 1.

[0028] The structure exhibits excellent adaptability during component connection: on the one hand, the rubber block can alleviate dimensional errors caused by installation tolerances, enhancing the compatibility and tolerance of the installation position of the fixing rod 2; on the other hand, it generates controllable deformation after being subjected to vertical pressure, playing a buffering role, absorbing construction vibration or impact loads, and effectively reducing the loosening of bolt 42 or fatigue failure of connecting parts caused by long-term stress concentration or micro-vibration.

[0029] like Figure 2 and Figure 3 As shown, to further enhance the overall stability of the structure, the anchor 11 structure has also been optimized. The anchor 11 has a sheet-like structure, with its thickness gradually decreasing along the direction away from the base plate 1, and its width also gradually narrowing, forming a wedge-shaped structure that facilitates insertion into the ground, making it easy to hammer or manually press into the construction ground.

[0030] Furthermore, the anchor 11 can be designed as a hollow structure with multiple grouting holes 111 evenly distributed on its peripheral wall for injecting fixing materials. The base plate 1 is correspondingly provided with an opening 15 communicating with the cavity of the anchor 11. Through this opening 15, cement mortar, epoxy resin, or other curing materials can be injected into the cavity of the anchor 11, resulting in a more robust ground anchoring effect after curing. This is particularly suitable for soft foundations or scenarios requiring long-term protective support.

[0031] In some extended embodiments, the base plate 1 may also be provided with limiting flanges or positioning holes to facilitate rapid positioning and engagement with pre-embedded parts in the ground, enabling prefabricated installation. Furthermore, each component can be pre-set with standardized connection holes to achieve mechanized and modular installation, reducing manual assembly errors and improving on-site work efficiency.

[0032] It should be noted that, in actual construction, a single protective plate 4 can be fitted with two or more sets of base plate 1 structures, depending on the dimensions of the adjacent edges and the required intensity of the work. Each set of base plate 1 structures is equipped with a complete set of swing rods 3, fixed rods 2, and diagonal braces 5. These components, together with the protective plate 4, form a multi-point support structure system. Through the cooperation of multiple base plates 1 and their connecting structures, the protective plate 4 can obtain a larger support surface and higher structural stability along its length, effectively coping with possible interference from wind loads, personnel collisions, or equipment vibrations at the construction site.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
