Description

Technical Field

[0001] This utility model relates to the field of support device technology, and in particular to a steel structure bracket support device for reinforcing existing buildings. Background Technology

[0002] Forklifts, as essential transportation and lifting machinery in modern construction, are widely used due to their convenience and flexibility. However, the safety and stability of materials lifted by the forklift's forks become a critical issue during actual construction. On uneven ground, with heavy or large materials, and in situations with high ceilings, the materials lifted by the forklift's forks are prone to swaying or tilting, posing safety hazards to construction workers. This is especially true during underground structure construction, which often involves numerous uncertainties such as complex geological conditions, underground water accumulation, or high water levels, all of which can threaten construction safety.

[0003] Therefore, how to provide a steel structure bracket support device for the reinforcement of existing buildings, which has a simple structure, is easy to operate, can safely and stably assist the forklift arm in lifting and jacking materials, and can provide a safe construction operation platform to adapt to complex and ever-changing construction site environments, and ensure construction safety and efficiency, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention proposes a steel structure bracket support device for the reinforcement of existing buildings, which aims to solve the technical problem that the forks of the traditional forklifts cannot stably and safely lift materials to a higher working height and cannot provide a safe construction platform.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a steel structure bracket support device for reinforcing existing buildings, including:

[0007] The fork arm stabilizing base has multiple support legs at its lower part and a set of socket holes at its upper part that can be adapted to be plugged and plugged into the fork arm of the forklift.

[0008] The lifting frame has its bottom end vertically fixed to the upper end of the fork arm stabilizing base; the top surface of the lifting frame serves as a material lifting and construction platform.

[0009] This utility model discloses a steel structure bracket support device for reinforcing existing buildings, which can be connected to a forklift for use. The forklift's fork arm is inserted into the socket group of the fork arm stable base. When the fork arm is raised, it supports the fork arm stable base, which can be firmly connected to the forklift's fork arm, thereby driving the entire lifting frame to lift and transport. When the fork arm is lowered, the support legs of the fork arm stable base can stand stably on the ground. At this time, it is more stable when loading materials on the top surface of the lifting frame or when personnel are getting on and off the lifting frame. The device can be detached from the forklift by pulling the forklift's fork arm out of the socket group. The forklift's forks engage with the socket assembly, ensuring stable connection even with slight left-right tilting of the forklift. The top surface of the lifting frame serves as a material lifting and construction platform for placing materials and / or supporting construction personnel. This is more stable than placing materials directly on the forks and can lift materials or personnel to greater heights. Combined with the forklift's flexibility and maneuverability, construction personnel can easily transfer and lift materials, adapting to a wider range of construction work heights and locations. It is suitable for various construction scenarios, especially those requiring frequent forklift material transfer and lifting. Furthermore, the top surface of the lifting frame can serve as a construction platform for personnel, improving construction efficiency and safety. This invention features a simple structure, easy operation, and safe and stable assistance to the forklift's forks in lifting materials, providing a safe construction platform to adapt to complex and changing construction site environments, ensuring construction safety and efficiency.

[0010] As a further improvement to the above technical solution, the lifting frame includes a bottom frame, a support column assembly, and a top frame; the bottom frame is fixed parallel to the upper end of the fork arm stable base; the lower end of the support column assembly is vertically fixed to the bottom frame; the top frame is arranged parallel to the bottom frame and fixed to the upper end of the support column assembly; the top surface of the top frame is a material lifting and construction platform for placing materials and / or supporting construction personnel.

[0011] The beneficial effects of the above technical solution are: the bottom frame of the lifting frame strengthens the stability of the bottom structure; the support column group improves the support strength and has a greater load-bearing capacity; the top surface of the top frame serves as a material lifting and construction platform, which facilitates the stable placement of materials and allows construction personnel to step on and stand on them.

[0012] As a further improvement to the above technical solution, the bottom frame includes multiple angle steels; the multiple angle steels are sequentially fixed end to end to form a rectangular bottom frame; the multiple angle steels are all fixed in parallel to the upper end of the fork arm stable base.

[0013] As a further improvement to the above technical solution, the support column group includes multiple angle steels II; the lower ends of the multiple angle steels II are all vertically fixed on the rectangular bottom frame and correspond one-to-one with the end connection of two adjacent angle steels I.

[0014] As a further improvement to the above technical solution, the top frame includes multiple angle steels; the multiple angle steels are sequentially fixed end to end to form a rectangular top frame; the upper ends of the multiple angle steels are all vertically fixed to the rectangular top frame and correspond one-to-one with the end connection points of two adjacent angle steels.

[0015] As a further improvement to the above technical solution, the top frame also includes angle steel four; angle steel four is located in the middle of the rectangular top frame, and the two ends of angle steel four are fixedly connected to two horizontally opposite angle steel three; the top surfaces of angle steel four and multiple angle steel three together constitute a material lifting and construction platform.

[0016] The beneficial effect of the above technical solution is that the setting of angle steel four further enhances the structural stability of the top frame.

[0017] As a further improvement to the above technical solution, the fork arm stable base includes multiple support legs, the upper ends of the multiple support legs are all vertically fixed to the bottom end of the rectangular bottom frame and correspond one-to-one to the direct below of the multiple angle steels.

[0018] Each of the support legs has a support leg at its lower end; each of the support legs has a socket at its upper end, and the sockets of the multiple support legs are arranged horizontally and in the same direction to form a socket group that can be adapted to be plugged and pulled into the fork arm of the forklift.

[0019] The beneficial effects of the above technical solution are: the support leg is arranged directly below the angle steel two that plays a supporting role, which can make the support leg support the lifting frame more stably; the socket hole is directly below the angle steel two, which can make the force support point of the forklift arm correspond to the angle steel two that plays a supporting role, making the overall lifting capacity of the lifting frame stronger and more stable.

[0020] As a further improvement to the above technical solution, the supporting leg includes angle steel five and two angle steel six; the two angle steel six are arranged horizontally opposite each other and their upper ends are vertically fixed to the bottom end of the rectangular bottom frame; angle steel five is located between the two angle steel six and its two ends are fixed one-to-one at the middle of the height direction of the two angle steel six; the lower part of the two angle steel six forms the supporting leg, and the upper opposing wall surfaces of the two angle steel six, the top surface of angle steel five and the corresponding bottom surface of the rectangular bottom frame together form a socket hole.

[0021] The beneficial effects of the above technical solution are: the support leg is arranged below the socket so that the socket is at a certain height from the ground when the support leg is standing on the ground, which facilitates the lifting and lowering adjustment of the fork arm to more flexibly insert or remove it from the socket.

[0022] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a steel structure bracket support device for reinforcing existing buildings, which has the following advantages and beneficial effects:

[0023] 1. This utility model has a simple structure and is easy to operate. It can effectively fix the forklift fork arm, prevent the materials on the forklift from shaking or shifting, and improve construction safety and efficiency.

[0024] 2. This utility model, by adjusting the arrangement of each component of the steel structure bracket support device, allows for height adjustment based on different ground heights, ensuring stable support for the forklift and adapting to various construction environments. The socket design of the fork arm stable connection base enables a tight connection between the steel structure bracket support device and the forklift's fork arm, ensuring the forklift's stability during operation.

[0025] 3. This utility model is made of welded angle steel, which can be arbitrarily assembled according to site requirements and the weight and size of materials. The angle steel is made of high-strength material, ensuring the stability and durability of the device. Furthermore, installation and disassembly with forklifts are simple; construction personnel can easily connect the device to the forklift with simple operations. If necessary, the fork arm support base can be temporarily welded and fixed to the forklift fork arm, further improving safety.

[0026] 4. The lifting frame and the fork arm stable base of this utility model are fully welded together, which ensures that the materials on the forklift will not shake or tilt during operation, thus improving construction safety. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] According to the embodiments of this utility model, such as Figures 1 to 6 As shown, a steel structure bracket support device for reinforcing existing buildings includes: a fork arm stabilizing base 1 and a lifting frame 2. The fork arm stabilizing base 1 is provided with multiple support legs 1111 at its lower part, and a socket group 113 at its upper part that can be adapted to be plugged and pulled into connection with the fork arm of a forklift; the bottom end of the lifting frame 2 is vertically fixed to the upper end of the fork arm stabilizing base 1; the top surface of the lifting frame 2 is a material lifting and construction platform 233.

[0040] This embodiment of a steel structure bracket support device for reinforcing existing buildings can be connected to a forklift for use. The forklift's fork arm is inserted into the socket group 113 of the fork arm stable base 1. When the fork arm is raised, it supports the fork arm stable base 1, which can stably connect the fork arm stable base 1 to the forklift's fork arm, thereby driving the entire lifting frame 2 to lift and transport.

At this time, it is more stable when loading materials on the top surface of the lifting frame 2 or when personnel are getting on and off the lifting frame 2. The device can be detached from the forklift by pulling the forklift's fork arm out of the socket group 113. The forklift's forks engage with the socket assembly 113, ensuring stable connection to the forklift even with slight left-right tilts. The top surface of the lifting frame 2 serves as a material lifting and construction platform 233 for placing materials and / or supporting construction personnel. This is more stable than placing materials directly on the forks and can lift materials or personnel to greater heights. Combined with the forklift's flexibility and maneuverability, construction personnel can easily transfer and lift materials, adapting to a wider range of construction work heights and locations. It is suitable for various construction scenarios, especially those requiring frequent forklift material transfer and lifting. Furthermore, the top surface of the lifting frame 2 can serve as a construction platform for personnel, improving construction efficiency and safety. This invention features a simple structure, easy operation, and safe and stable assistance to the forklift's forks in lifting and jacking materials, providing a safe construction platform to adapt to complex and changing construction site environments, ensuring construction safety and efficiency.

[0041] In some embodiments, the lifting frame 2 includes a bottom frame 21, a support column assembly 22, and a top frame 23; the bottom frame 21 is fixed parallel to the upper end of the fork arm connecting base 1; the lower end of the support column assembly 22 is vertically fixed to the bottom frame 21; the top frame 23 is arranged parallel to the bottom frame 21 and fixed to the upper end of the support column assembly 22; the top surface of the top frame 23 is a material lifting and construction platform 233 for placing materials and / or carrying construction personnel.

[0042] The bottom frame 21 of the lifting frame 2 enhances the stability of the bottom structure; the support column group 22 increases the support strength and has a greater load-bearing capacity; the top surface of the top frame 23 serves as a material lifting and construction platform 233, which facilitates the stable placement of materials and allows construction personnel to step on and stand on them.

[0043] In some embodiments, the bottom frame 21 includes a plurality of angle steels 211; the plurality of angle steels 211 are welded and fixed end to end in sequence to form a rectangular bottom frame; the plurality of angle steels 211 are all welded and fixed in parallel to the upper end of the fork arm stable base 1.

[0044] In some embodiments, the support column group 22 includes a plurality of angle steels 221; the lower ends of the plurality of angle steels 221 are vertically welded and fixed to the rectangular bottom frame and correspond one-to-one with the end connection of two adjacent angle steels 211.

[0045] In some embodiments, the top frame 23 includes a plurality of angle steel 3s 231s; the plurality of angle steel 3s 231s are welded and fixed end to end in sequence to form a rectangular top frame; the upper ends of the plurality of angle steel 2s 221s are all vertically welded and fixed on the rectangular top frame and correspond one-to-one with the end connection of two adjacent angle steel 3s 231s.

[0046] In some embodiments, the top frame 23 further includes angle steel 232; angle steel 232 is located in the middle of the rectangular top frame, and the two ends of angle steel 232 are welded and fixed to two horizontally opposite angle steels 231; the top surfaces of angle steel 232 and multiple angle steels 231 together constitute a material lifting and construction platform 233.

[0047] The installation of angle steel 4232 further enhances the structural stability of the top frame 23.

[0048] In some embodiments, the fork arm stabilizing base 1 includes a plurality of support legs 11, the upper ends of which are vertically welded and fixed to the bottom of the rectangular bottom frame and correspond one-to-one to the area directly below a plurality of angle steels 221.

[0049] Each support leg 11 has a support leg 1111 at its lower end and a socket hole 1131 at its upper end. The socket holes 1131 of the multiple support legs 11 are arranged in the same direction along the horizontal direction to form a socket hole group 113 that can be adapted to be plugged and plugged into the fork arm of the forklift.

[0050] The support leg 11 is positioned directly below the supporting angle steel 221, which allows the support leg 1111 to more stably support the lifting frame 2; the socket hole 1131 is positioned directly below the supporting angle steel 221, which allows the force support point of the forklift arm to be aligned with the supporting angle steel 221, making the overall lifting capacity of the lifting frame 2 stronger and more stable.

[0051] In some embodiments, the support leg 11 includes angle steel five 112 and two angle steel six 111; the two angle steel six 111 are arranged horizontally opposite each other and their upper ends are vertically welded and fixed to the bottom end of the rectangular bottom frame; angle steel five 112 is located between the two angle steel six 111 and its two ends are vertically welded and fixed to the middle of the height direction of the two angle steel six 111; the lower part of the two angle steel six 111 forms the support leg 1111, and the upper opposite wall surface of the two angle steel six 111, the top surface of angle steel five 112 and the bottom surface of the corresponding rectangular bottom frame together form the socket hole 1131.

[0052] The support leg 1111 is arranged below the socket 1131 so that when the support leg 1111 is standing on the ground, the socket 1131 is at a certain height from the ground, which facilitates the lifting and lowering adjustment of the fork arm to more flexibly insert or remove it from the socket 1131.

[0053] Specifically, to further optimize the overall performance of the device and improve its practicality and safety, some additional functions can be carefully designed into the device. Anti-slip pads are bolted to the bottom of each angle steel 6111. The anti-slip pads significantly increase the friction between the device and the ground, effectively preventing slippage during operation due to external forces or slippery ground, thus providing a more reliable safety guarantee for the construction process.

[0054] Specifically, warning signs should be reasonably arranged on the angle steel 221 of the support column group 22 and / or the angle steel 111 of the support leg 11. Conspicuous warning signs can promptly remind construction personnel to pay attention to potential dangers during the construction process, prompt them to strictly abide by safe operating procedures, thereby effectively reducing the probability of safety accidents and creating a safer construction environment.

[0055] Specifically, the lifting frame of the steel structure consists of two parts, each made of 13 equilateral angle steels of specification 20# (200×14) (four angle steels of specification 1-211, four angle steels of specification 221, four angle steels of specification 231, and one angle steel of specification 232), connected by a precise welding process to form a complete and stable frame structure. In actual engineering applications, the dimensions of the steel structure support frame are not fixed, but are flexibly selected according to specific engineering requirements. This design consideration aims to ensure that the device not only has excellent stability, but also can effectively support various materials under different working conditions, meeting diverse construction requirements.

[0056] Secondly, the design of the steel forklift arm stable base 1 is equally ingenious. At the four key footings at the bottom of the steel lifting frame 2, a reliable welding connection is used to tightly connect it to the steel forklift arm stable base 1, forming an organic whole structure. It is worth noting that the angle steel 112 (5) and 111 (6) used to construct the forklift arm stable base 1 are both made of 20# (200×14) equilateral angle steel. The dimensions of the base are not arbitrary but are carefully considered, taking into account factors such as the size and spacing of the forklift arms and the actual engineering environment. This meticulous design allows the steel structure bracket support device to achieve a smooth and tight connection with the forklift arms, greatly improving the mobility and operability of the device on the construction site. Furthermore, considering the complexity of the ground conditions at the construction site, the steel structure base has the function of adapting to the unevenness of the ground. This feature ensures that the device can maintain a stable placement under various ground conditions, effectively avoiding safety hazards and structural instability caused by uneven ground. In the design of the steel structure base, stability and durability are always the core considerations. Stability ensures the safety of the device during load-bearing and transportation, while durability guarantees the reliability of the device during long-term use, reducing increased costs and project delays caused by frequent component replacements.

[0057] Specifically, the lifting frame 2 is 1100mm long, 1100mm wide, and 1000mm high; angle steel 1 211, angle steel 2 221, and angle steel 3 231 are all 1000mm long; angle steel 4 232 is 700mm long; angle steel 5 112 is 230mm long; and angle steel 6 111 is 250mm high.

[0058] It should be noted that the specific specifications and dimensions of angle steel 1.211, angle steel 2.221, angle steel 3.231, angle steel 4.232, angle steel 5.112 and angle steel 6.111 can be flexibly set as needed.

[0059] The steel structure bracket support device provided by this utility model is easy to fix to a forklift. For long-term use or when a stable connection is required, angle steel 5112 or angle steel 6111 can be welded and fixed to the forklift's fork arm. When separation is needed, the weld joint can be separated using a cutting machine; or the angle steel 5112 or angle steel 6111 can be fastened to the forklift's fork arm with bolts, facilitating disassembly and assembly. A forklift equipped with the steel structure bracket support device can easily and stably lift the steel beams of the steel structure support and reinforcement platform. Underground structure construction involves many uncertainties, such as complex geological conditions and high groundwater levels, which can threaten construction safety. Using the steel structure bracket support device for jacking assistance can effectively distribute and bear the load during construction, enhance the stability and safety of the structure, reduce the risk of collapse and other safety accidents, and ensure the forming effect. It improves work efficiency, installation quality, and reduces construction costs. This device is easy to set up, can be reused repeatedly, and can be extended to other construction projects that use forklift-assisted jacking.
