Description

Technical Field

[0001] This utility model relates to the field of I-beam scaffolding technology, and in particular to an I-beam scaffolding support structure. Background Technology

[0002] During construction, especially for high-rise buildings, scaffolding is often erected before construction begins to enable workers to operate at heights. The scaffolding is built layer by layer along the building's height. Workers then stand on the scaffolding to perform their tasks at these heights.

[0003] Because the scaffolding cantilevered out of the building structure, in order to ensure the stability and safety of the scaffolding and to provide support points, existing technology uses cantilever beams installed on the wall. These cantilever beams are often high-strength I-beams. Specifically, they are attached to the wall by tie rods at the inner ends of the I-beams.

[0004] However, in actual work, it was found that when the cantilever length of the cantilever beam is large, simply relying on tie rods to anchor it from the inner end of the I-beam is not very stable. This is because the scaffolding structure supports the outer end of the I-beam, thus the structural stability of the cantilevered I-beam is not high. Furthermore, at heights, if the stability of the cantilevered I-beam installation structure cannot be guaranteed, construction safety cannot be effectively ensured.

[0005] Furthermore, during construction, a large amount of construction materials, such as cement, mortar, and pipes, often need to be supported and placed on the scaffolding. The outer end of the cantilevered I-beam, which serves as the supporting structure of the scaffolding, bears a very large load. Therefore, traditional construction sites often impose restrictions on the weight of construction personnel and materials on the scaffolding to ensure that the load-bearing capacity of the cantilevered I-beam is within a safe range.

[0006] Therefore, in actual work, especially for steel beams with large cantilever lengths, if structural reinforcement cannot be carried out to increase the load on the steel beams, it will not only affect construction efficiency, but more seriously, it will be impossible to effectively guarantee the safety of construction.

[0007] Furthermore, during construction, if a steel beam with a large cantilever length exceeds its bearing capacity, the beam is prone to bending or even falling off the wall, which can lead to very serious accidents, especially personal injury. Secondly, after a large area of ​​scaffolding collapses from a height, the scaffolding is severely damaged, and even if the scaffolding is reused, its safety cannot be guaranteed, resulting in a reduction in the turnover efficiency of the scaffolding. Utility Model Content

[0008] Based on the above background, the purpose of this utility model is to provide an I-beam scaffolding support structure.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An I-beam scaffolding support structure includes several cantilevered I-beam units for supporting the scaffolding;

[0011] The cantilevered I-beam units are connected sequentially by connecting arm structures;

[0012] Each cantilevered I-beam unit includes an I-beam, with the top of the I-beam pulled to the wall by an upper pull arm structure and the bottom of the I-beam supported to the wall by a lower support arm structure.

[0013] The upper pull arm structure and the lower support arm structure both include a first arm and a second arm arranged in a triangle with the I-beam; the first arm and the second arm are respectively connected to the proximal end and the distal end of the I-beam;

[0014] The first boom and the second boom are respectively equipped with embedded parts;

[0015] The inner end of the I-beam can be detachably connected to the wall via a detachable pre-embedded connector.

[0016] Preferably, the I-beam is welded with a pin seat that mates with the first arm and the second arm, a pin is inserted into the pin seat, and the first arm and the second arm are fixedly connected with lugs that mate with the pins. The two ends of the pin are threaded with anti-loosening nuts.

[0017] Preferably, the embedded part includes an attachment plate attached to the outer wall of the wall, and a pair of embedded hook bars are fixedly connected to the inner end of the attachment plate;

[0018] The attachment plate is welded with mounting pin seats for mounting the first arm and the second arm, and the first arm and the second arm are fixed to the mounting pin seats by pins.

[0019] Preferably, a pair of pin inserts are slidably connected to the mounting pin seat, and pin tongues that engage with the pin inserts are fixedly connected to the first arm and the second arm respectively, and anti-loosening nuts are threaded onto the outer ends of the pin inserts.

[0020] Preferably, a mounting plate is welded to the inner end of the I-beam;

[0021] The mounting plate is welded with several tie rods that pass through the wall;

[0022] The tie rod passes through the detachable pre-embedded connector.

[0023] Preferably, the detachable pre-embedded connector includes a pull plate attached to the back of the wall, and a plurality of screw sleeves that cooperate with the tie rods are welded on the pull plate, with the tie rods passing through the screw sleeves;

[0024] The pull plate has a through hole for connecting the screw sleeve, and the pull screw passes through the through hole;

[0025] The tie rod is threaded with a fastening nut that abuts against the pull plate.

[0026] Preferably, a pair of hook bars are welded to the pull plate to hook and pull it tightly onto the steel cage inside the wall.

[0027] Preferably, the connecting arm structure connects the sidewalls of adjacent I-beams that face each other;

[0028] The connecting arm structure includes a first connecting arm and a second connecting arm;

[0029] Tongue plates are fixedly connected to both ends of the first connecting arm and the second connecting arm respectively;

[0030] The side wall of the I-beam is welded with a pin seat that mates with the tongue plate, and a pin shaft is inserted into the pin seat and fixed to the tongue plate.

[0031] Preferably, the first connecting arm and the second connecting arm are arranged at an angle.

[0032] This utility model has the following beneficial effects:

[0033] 1. A triangular tension structure is formed at the top of the I-beam via the first and second booms, while a triangular support structure is formed at the bottom of the I-beam via the same first and second booms. Therefore, the cooperation of the upper and lower triangular structures significantly improves the load-bearing capacity of the cantilevered steel beam. Furthermore, because the first and second booms are positioned at different points along the length of the I-beam, multi-point reinforcement and support are achieved, further increasing the structural stability of the steel beam and preventing the defects caused by excessive deformation under pressure (especially internal damage), which could reduce the structural safety.

[0034] 2. The connecting arm structure connects the side walls of adjacent I-beams facing each other, forming an integrated structure. This increases the overall structural strength and prevents a loosening or weakening of a single I-beam from severely impacting the stability of the scaffold. In other words, the connecting arm structure integrates each cantilevered I-beam unit into a single structure. Even if a single cantilevered I-beam unit in the integrated structure becomes loose during construction, the overall structure can still maintain high stability thanks to the connection of the connecting arm structure.

[0035] 3. The cantilevered I-beam disclosed in this utility model not only boasts high structural safety and stability when tensioned with the wall, but also significantly improves the structural stability and safety of the scaffolding supported by the cantilevered I-beam. This effectively ensures the safety of construction workers and increases the safety of the scaffolding in use, avoiding the technical defects of excessive scaffolding wear and tear and low turnover efficiency caused by accidents.

[0047] Example 1

[0048] like Figure 1-6 As shown, an I-beam scaffolding support structure includes several cantilevered I-beam units 2 for supporting the scaffolding; similar to existing construction methods, the cantilevered I-beam units 2 are constructed along the length of the wall, and after construction, the scaffolding is erected.

[0049] To fundamentally improve the structural stability of the cantilevered I-beams, including their compressive strength, the aforementioned cantilevered I-beam units 2 are connected sequentially via connecting arm structures. Simultaneously, each cantilevered I-beam unit 2 is supported by upward and downward supports to the wall 1, achieving stable installation of the cantilevered I-beam unit 2 while simultaneously improving its compressive capacity.

[0050] Specifically, each cantilevered I-beam unit 2 includes an I-beam 21 (same as the existing construction, the scaffolding in the later stage is built with the outer end of the cantilevered I-beam 21 as the support point). The top of the I-beam 21 is pulled to the wall 1 by the upper pull arm structure 23, and the bottom of the I-beam 21 is supported to the wall 1 by the lower support arm structure 26 (the upper pull arm structure 23 and the lower support arm structure 26 are set symmetrically).

[0051] Specifically, both the upper pull arm structure 23 and the lower support arm structure include a first arm 232 and a second arm 231 arranged in a triangular shape with the I-beam 21; the first arm 232 and the second arm 231 are respectively connected to the proximal and distal ends of the I-beam 21.

[0052] In this way, structurally, the top of the I-beam 21 forms a triangular tension structure through the first arm 232 and the second arm 231, while the bottom of the I-beam 21 forms a triangular support structure through the first arm 232 and the second arm 231. Therefore, the cooperation of the upper and lower triangular structures significantly improves the load-bearing capacity of the cantilevered steel beam. Furthermore, because the first arm 232 and the second arm 231 provide tension and support at different positions along the length of the I-beam 21, multi-point reinforcement and support are achieved, further increasing the structural stability of the steel beam and avoiding the drawbacks of deformation (especially internal damage) under excessive pressure, which could lead to a decrease in structural safety.

[0053] The first boom 232 and the second boom 231 are connected to the I-beam 21 in the following way:

[0054] The I-beam 21 is welded with a pin seat (U-shaped structure) that mates with the first arm 232 and the second arm 231. A pin is inserted into the pin seat. The first arm 232 and the second arm 231 are fixedly connected with lugs that mate with the pin. The two ends of the pin are threaded with anti-loosening nuts.

[0055] Meanwhile, the other ends of the first boom 232 and the second boom 231 are hung on the wall 1. Specifically, in order to increase the stability of the hangership with the wall 1, the first boom 232 and the second boom 231 are respectively equipped with embedded parts.

[0056] The embedded parts are pre-installed on wall 1 during the construction of the steel reinforcement cage of wall 1.

[0057] Specifically, the embedded part includes an attachment plate 233 attached to the outer wall of the wall 1, and a pair of embedded hook bars 2331 (symmetrically arranged vertically) are fixedly connected to the inner end of the attachment plate 233.

[0058] During the construction of the steel reinforcement cage of wall 1, the pre-embedded hook bars 2331 on the pre-embedded parts are hung on the steel reinforcement cage in the same way as in the existing method. After being hung, they are fixed by means such as wire binding. After the concrete of the steel reinforcement cage of wall 1 is poured, the attachment plate 233 is attached to the outer wall of wall 1. This provides a foundation for the subsequent installation of the I-beam.

[0059] The aforementioned auxiliary plate 233 is welded with mounting pin seats 2332 for mounting the first arm 232 and the second arm 231. The first arm 232 and the second arm 231 are fixed to the mounting pin seats 2332 by pins.

[0060] Specifically, the method of fixing the pin is the same as described above. A pair of pin rods are slidably connected to the mounting pin seat 2332. The first arm 232 and the second arm 231 are respectively fixedly connected with pin tongues that engage with the pin rods. The outer end of the pin rod is threaded with an anti-loosening nut.

[0061] This method enables the I-beam 21 to be installed on the wall 1 via the upper pull arm structure 23 and the lower support arm structure 26.

[0062] Example 2

[0063] like Figure 1-6 As shown, in this embodiment, based on the structure of Embodiment 1, the inner end of the aforementioned I-beam 21 is detachably connected to the wall 1 via a detachable pre-embedded connector 24. Specifically, a mounting plate 211 is welded to the inner end of the I-beam 21; four rectangular tie rods 244 are welded onto the mounting plate 211, extending through the wall 1. The tie rods 244 pass through the detachable pre-embedded connector 24.

[0064] Specifically, the detachable pre-embedded connector 24 includes a pull plate 241 attached to the back of the wall 1. Several screw sleeves 242 that cooperate with the pull screws 244 are welded on the pull plate 241. The pull screws 244 pass through the screw sleeves 242. The pull plate 241 has a through hole that communicates with the screw sleeves 242. The pull screws 244 pass through the through hole. A fastening nut that abuts against the pull plate 241 is threaded onto the pull screws 244.

[0065] Similarly, the detachable pre-embedded connector 24 is also hung on the steel cage as a pre-embedded structure before the concrete is poured into the steel cage of the wall 1. Specifically, according to the existing pre-embedded component structure design, a pair of hook bars 243 are welded on the above-mentioned pull plate 241, which are hooked and hung on the steel cage inside the wall 1.

[0066] After the reinforcing cage is poured, the tie plate 241 is attached to the back of the wall 1. During the installation of the I-beam 21, the tie rod 244 is passed through the four threaded sleeves 242, and then the fastening nuts are tightened.

[0067] The advantages of the above structural design are as follows: the detachable embedded connector 24, which serves as the direct connection between the I-beam 21 and the wall 1, uses a tie plate 241 and hook reinforcement 243 as embedded structural elements, which are then hung on the reinforcing cage of the wall 1. This further increases the adhesion stability between the I-beam 21 and the wall 1, thereby increasing the structural strength. Secondly, this structural design facilitates the disassembly of the I-beam 21 after construction. The I-beam 21 can be directly pulled out after loosening the fastening nut.

[0068] In the actual concrete pouring process, according to the existing method, both ends of the screw sleeve 242 are blocked with rubber plugs or tape to prevent the concrete from flowing in and blocking the screw sleeve 242 after it has solidified.

[0069] Example 3

[0070] like Figure 1-6 As shown, this embodiment, based on the structure of embodiment 2, aims to integrate all installed I-beams 21 into a single structure, increasing overall structural strength and preventing any loosening or low bearing capacity of a single I-beam 21 from severely impacting the stability of the overall scaffolding. Therefore, a connecting arm structure 25 connects the sidewalls of adjacent I-beams 21 facing each other. In other words, the connecting arm structure 25 integrates each cantilevered I-beam 21 unit 2 into a single structure. Even if a single cantilevered I-beam 21 unit 2 in the integrated structure becomes loose during construction, the connecting arm structure 25 ensures that the overall structure maintains high stability.

[0071] Specifically, the connecting arm structure 25 includes a first connecting arm 251 and a second connecting arm 252; both ends of the first connecting arm 251 and the second connecting arm 252 are fixedly connected to tongue plates; a pin seat that mates with the tongue plate is welded to the side wall of the I-beam 21, and a pin rod that is pinned to the tongue plate is inserted into the pin seat (similarly, the outer end of the pin rod is threaded to an anti-loosening nut). The first connecting arm 251 and the second connecting arm 252 are inclined.

[0072] During construction, after the I-beams 21 are erected in the manner described above, the connecting arm structure 25 is sequentially connected to each I-beam 21. Through this structure, all I-beams 21 form an integrated structure, thereby further increasing the stability and safety of the pressure-bearing scaffold under the action of the overall structural strength.

[0073] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
