Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a platform frame used for high-altitude steel structure construction. Background Art

[0002] In the diverse steel structure construction environment, the safety and protection of workers is always of paramount importance. Given that processes such as steel structure installation and welding often carry risks associated with working at height, to ensure the safety of workers and effectively prevent all types of casualties, it is imperative to strictly adhere to construction regulations and fully implement various safety measures. Through a systematic and standardized safety management system, we can build a solid line of defense for frontline workers and ensure the safe and orderly progress of the entire construction process.

[0003] At present, there are two more traditional methods for safety protection during high-altitude operations on steel structures. The first is to install safety ropes and wear safety belts near existing structures through pre-buried fixation and other methods, and then carry out rope hanging construction; the second is to install vertical poles at both ends of the main working surface of the steel structure, and then install safety ropes and wear safety belts on the vertical poles; the third is to set up a safety net.

[0004] The first method of installing a safety rope on an existing structure has certain limitations. It can only be used when the steel structure operation surface is close to an existing building structure, and it is necessary to pre-embed the connectors in advance or subsequently connect with expansion bolts, etc., which is inconvenient to install, and the feet can only step on the edge of the steel plate of the steel structure; the second method uses a vertical pole safety rope. Personnel can only work along the direction of the safety rope under the condition of wearing a safety belt, and their feet can only step on the edge of the steel plate of the steel structure. The working space is extremely limited, and construction work is restricted; the third type of safety net protection, due to insufficient support force of the safety net, personnel must use it under the condition of wearing a safety belt, and the installation of the safety belt must be carried out on the basis of one of the first two safety protections, which is more cumbersome. Summary of the Invention

[0005] Therefore, the present invention aims to solve the problems of inconvenient installation and limited space for construction personnel in the existing steel structure aerial work platform, thereby providing a platform frame for high-altitude steel structure construction.

[0006] In order to solve the above technical problems, the technical solutions of the present invention are as follows:

[0007] A platform frame for high-altitude steel structure construction, comprising:

[0008] Four L-shaped corner members are provided, each end of which is provided with a first oblique slot and a first oblique fixing block;

[0009] The side members are T-shaped and are provided with at least four of them. The four side members are spaced and connected between the four corner members. The two ends of the long sides and one end of the short sides of the side members are provided with second oblique slots and second oblique fixing blocks. The second oblique slots are adapted to the first oblique fixing blocks, and the second oblique fixing blocks are adapted to the first oblique slots. The long sides of the side members are engaged with the ends of the corner members.

[0010] The central connecting member is cross-shaped and is provided with at least one. The four sides of the central connecting member are provided with a third oblique slot and a third oblique fixing block. The third oblique slot is adapted to the second oblique fixing block, and the third oblique fixing block is adapted to the second oblique slot. The four sides of the central connecting member are respectively engaged with the short sides of the four side members.

[0011] Furthermore, the corner member is provided with a plurality of the first oblique slots and the first oblique fixing blocks spaced apart along the length direction thereof, the side member is provided with a plurality of the second oblique slots and the second oblique fixing blocks spaced apart along the length direction of the corresponding end portion thereof, and the central connecting member is provided with a plurality of the third oblique slots and the third oblique fixing blocks spaced apart along the length direction thereof.

[0012] Furthermore, the first oblique card slot, the first oblique fixing block, the second oblique card slot, the second oblique fixing block, the third oblique card slot, and the third oblique fixing block are all the same in shape and length, width, and height.

[0013] Furthermore, the first oblique slot is arranged between two adjacent first oblique fixing blocks, and the distribution of several first oblique slots and first oblique fixing blocks extends to the end of the corner member, and the end structure of the side member and the central connecting member is the same as the end structure of the corner member.

[0014] Furthermore, the number of the first oblique card slots, the first oblique fixing blocks, the second oblique card slots, the second oblique fixing blocks, the third oblique card slots, and the third oblique fixing blocks are the same.

[0015] Furthermore, the first oblique slot and the first oblique fixing block are inclined at one end away from the corner member toward the direction away from the end of the corner member; the second oblique slot and the second oblique fixing block are inclined at one end away from the side member toward the direction away from the end of the side member; the third oblique slot and the third oblique fixing block are inclined at one end away from the central connecting member toward the center of the central connecting member, and the inclination angle is 45°.

[0016] Further, the thicknesses of the corner member, the side member, and the central connecting member are the same, and the heights of the first diagonal card slot and the first diagonal fixing block are both greater than half of the thickness of the corner member.

[0017] Further, the corner member, the side member, and the central connecting member are all symmetric structures.

[0018] Further, reserved holes are provided in the middle parts of the corner member, the side member, and the central connecting member.

[0019] Further, the corner member, the side member, and the central connecting member are all made of metal materials.

[0020] The technical solution of the present invention has the following advantages:

[0021] 1. The platform frame for high-altitude steel structure construction provided by the present invention respectively and spacedly clamps 4 side members between 4 corner members to form a synthetic frame structure, and then connects the side members with the central connecting member to be installed in the middle of the frame structure, capable of forming a grid platform frame in a cross shape, facilitating laying on the steel structure frame to form a support frame of the working platform. The connection method of clamping enables the structure to be easily disassembled and installed, and can be reused. The assembled cross-shaped platform frame can directly lay materials such as wooden boards or steel grating sheets at the construction site on it for easy walking, greatly improving the activity space. In this way, construction workers can directly carry out construction above the steel structure. The cooperative connection between the diagonal card slot and the diagonal fixing block enables the corner member, the side member, and the central connecting member to be inserted and fitted from the side. This plug-in method can convert the vertical force into a fastening force, and the greater the force, the tighter the connection, ensuring the structural stability when vertically stressed. At the same time, this shaped structure can evenly disperse the force during use. When subjected to an external force, each part jointly bears the force, avoiding stress concentration at a certain point or on a certain side, thereby maintaining overall stability; the cross nodes of the horizontal and vertical members on the central connecting member in the middle of the cross-shaped grid support structure enhance the overall rigidity, enabling the platform frame to withstand large vertical and horizontal loads. While bearing a large weight, it is not prone to deformation and damage; at the same time, this frame-shaped platform frame, compared with other construction platform support frames, can save the use of materials while meeting the support requirements, reducing the construction cost.

[0022] 2. The platform frame for high-altitude steel structure construction provided by the present invention comprises a plurality of first oblique slots and first oblique fixing blocks spaced apart along their lengths on the corner members, a plurality of second oblique slots and second oblique fixing blocks spaced apart along the lengths of their corresponding ends on the side members, and a plurality of third oblique slots and third oblique fixing blocks spaced apart along their lengths on the central connecting member. This arrangement, through the provision of the plurality of first oblique slots, the plurality of first oblique fixing blocks, the plurality of second oblique slots, the plurality of second oblique fixing blocks, the plurality of third oblique slots, and the plurality of third oblique fixing blocks, improves the connection strength between the corner members, the side members, and the central connecting member.

[0023] 3. In the platform frame for high-altitude steel structure construction provided by the present invention, the first oblique slot, first oblique fixing block, second oblique slot, second oblique fixing block, third oblique slot, and third oblique fixing block all have identical shapes and dimensions (length, width, and height). This arrangement allows the matching oblique slots and oblique fixing blocks to be adjusted in position, achieving controllable length adjustment to meet the needs of different working conditions.

[0024] 4. The platform frame for high-altitude steel structure construction provided by the present invention features a first oblique slot positioned between two adjacent first oblique fixing blocks. Several first oblique slots and first oblique fixing blocks extend to the ends of the corner members, while the end structures of the side members and central connecting member are identical. This arrangement, by extending the oblique slots and oblique fixing blocks to the ends of the corresponding members, facilitates adjustment of the length of the interlocking fit between the members, facilitating adaptation to the size of the steel member. Furthermore, when additional construction work surfaces are needed, side members and central connecting members can be added directly.

[0025] 5. In the platform frame for high-altitude steel structure construction provided by the present invention, the plurality of first oblique slots, the plurality of first oblique fixing blocks, the plurality of second oblique slots, the plurality of second oblique fixing blocks, the plurality of third oblique slots, and the plurality of third oblique fixing blocks are all provided in equal numbers. This arrangement allows for the matching oblique slots and oblique fixing blocks on different components to be plugged into each other during connection, thereby improving connection stability.

[0026] 6. In the platform frame for high-altitude steel structure construction provided by the present invention, the first oblique slot and the first oblique fixing block, with their ends distal to the corner members, are both inclined toward the corner member ends; the second oblique slot and the second oblique fixing block, with their ends distal to the side members, are both inclined toward the side member ends; and the third oblique slot and the third oblique fixing block, with their ends distal to the central connecting member, are both inclined toward the center of the central connecting member, with each angle of inclination being 45°. This arrangement ensures the connection strength between the matching oblique slots and oblique fixing blocks, ensuring structural stability under vertical loads and preventing disconnection between components due to vertical loads.

[0027] 7. In the platform frame for high-altitude steel structure construction provided by the present invention, the corner members, side members, and central connecting member are all of uniform thickness, and the height of the first oblique retaining slot and the first oblique fixing block are both greater than half the thickness of the corner member. This arrangement ensures a tight connection between the matching oblique retaining slots and oblique fixing blocks.

[0028] 8. The platform frame for high-altitude steel structure construction provided by the present invention has symmetrical structures of corner members, side members, and central connecting members. This arrangement eliminates the need to distinguish between left and right when connecting the members, improving the convenience of assembly.

[0029] 9. The platform frame for high-altitude steel structure construction provided by the present invention has pre-set holes in the center of the corner members, side members, and central connecting member. This arrangement allows the installation of protective poles through the pre-set holes, eliminating the need to drill additional holes in the steel structure being built or constructed.

[0040] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0043] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] like Figure 1-Figure 5A platform frame for high-altitude steel structure construction as shown includes corner members 1, side members 2 and a central connecting member 3; the corner members 1 are L-shaped, with 4 provided, and first diagonal chutes 11 and first diagonal fixing blocks 12 are provided at both ends thereof; the side members 2 are T-shaped, with at least 4 provided, and the 4 side members 2 are connected at intervals between the 4 corner members 1. Second diagonal chutes 23 and second diagonal fixing blocks 24 are provided at both ends of the long side 21 and one end of the short side 22 of the side member 2. The second diagonal chutes 23 are adapted to the first diagonal fixing blocks 12, and the second diagonal fixing blocks 24 are adapted to the first diagonal chutes 11. The long side 21 of the side member 2 is clamped with the end of the corner member 1; the central connecting member 3 is cross-shaped, with at least 1 provided, and third diagonal chutes 31 and third diagonal fixing blocks 32 are provided on the 4 sides of the central connecting member 3. The third diagonal chutes 31 are adapted to the second diagonal fixing blocks 24, and the third diagonal fixing blocks 32 are adapted to the second diagonal chutes 23. The 4 sides of the central connecting member 3 are respectively clamped with the short sides 22 of the 4 side members 2.

[0045] For this platform frame for high-altitude steel structure construction, the 4 side members 2 are respectively clamped at intervals between the 4 corner members 1 to form a combined frame structure, and then the central connecting member 3 is connected to the side members 2 to be installed in the middle of the frame structure, capable of forming a grid platform frame in the shape of a Chinese character "tian", facilitating laying on the steel structure 5 frame to form a support frame for the operation platform. The connection method of clamping enables the structure to be easily disassembled and installed, and can be reused. The assembled grid platform frame in the shape of a Chinese character "tian" can directly lay materials such as wooden boards or steel mesh sheets 7 at the construction site that are convenient for walking on it, greatly improving the activity space. With such a setting, construction workers can directly carry out construction above the steel structure 5. The combined connection of the diagonal chutes and the diagonal fixing blocks enables the corner members 1, side members 2 and central connecting member 3 to be inserted and fitted from the side. This plug-in method can convert the vertical force into a fastening force, and the greater the force, the tighter the connection, ensuring the structural stability when vertically stressed. At the same time, the structure of this shape can evenly disperse the force during use. When subjected to an external force, each part works together to bear the force, avoiding stress concentration at a certain point or on a certain side, thus maintaining overall stability; the cross nodes of the horizontal and vertical members on the central connecting member 3 in the middle of the grid support structure in the shape of a Chinese character "tian" enhance the overall rigidity, enabling the platform frame to bear large vertical and horizontal loads. While bearing a large weight, it is not easy to deform and damage; at the same time, this frame-shaped platform frame, compared with other construction platform support frames, can save the use of materials while meeting the support requirements, reducing the construction cost.

[0046] In this embodiment, the corner member 1 is provided with a plurality of first oblique slots 11 and first oblique fixing blocks 12 spaced apart along its length, the side member 2 is provided with a plurality of second oblique slots 23 and second oblique fixing blocks 24 spaced apart along the length of its corresponding end portion, and the central connecting member 3 is provided with a plurality of third oblique slots 31 and third oblique fixing blocks 32 spaced apart along its length. This arrangement, through the provision of the plurality of first oblique slots 11, the plurality of first oblique fixing blocks 12, the plurality of second oblique slots 23, the plurality of second oblique fixing blocks 24, the plurality of third oblique slots 31, and the plurality of third oblique fixing blocks 32, improves the connection strength between the corner member 1, the side member 2, and the central connecting member 3.

[0047] Specifically, the first oblique slot 11, the first oblique fixing block 12, the second oblique slot 23, the second oblique fixing block 24, the third oblique slot 31, and the third oblique fixing block 32 all have the same shape and dimensions (length, width, and height). This arrangement allows for the matching oblique slots and oblique fixing blocks to be shifted and aligned. Specifically, the oblique slots can be moved forward and backward to engage with the matching oblique fixing blocks, allowing for fine adjustments and control of the displacement length as needed. This allows for length adjustment within a controllable range to meet the needs of different working conditions.

[0048] Specifically, a first oblique slot 11 is positioned between two adjacent first oblique fixing blocks 12. Several first oblique slots 11 and first oblique fixing blocks 12 extend to the ends of the corner member 1. The end structures of the side members 2 and the central connecting member 3 are identical to those of the corner member 1. This arrangement, by extending the oblique slots and oblique fixing blocks to the ends of the corresponding members, facilitates adjustment of the interlocking length between the members, facilitating adaptation to the size of the steel member. Furthermore, if additional work surface is needed, the side members 2 and central connecting member 3 can be added directly.

[0049] In this embodiment, the number of first oblique slots 11, the plurality of first oblique fixing blocks 12, the plurality of second oblique slots 23, the plurality of second oblique fixing blocks 24, the plurality of third oblique slots 31, and the plurality of third oblique fixing blocks 32 are equal. This arrangement allows all matching oblique slots and oblique fixing blocks on different components to be plugged into each other during connection, thereby improving connection stability.

[0050] In this embodiment, the ends of the first oblique slot 11 and the first oblique fixing block 12 facing away from the corner member 1 are both inclined toward the end of the corner member 1; the ends of the second oblique slot 23 and the second oblique fixing block 24 facing away from the side member 2 are both inclined toward the end of the side member 2; and the ends of the third oblique slot 31 and the third oblique fixing block 32 facing away from the central connecting member 3 are both inclined toward the center of the central connecting member 3, with each inclination angle being 45°. This arrangement ensures the connection strength between the corresponding oblique slots and oblique fixing blocks, ensuring structural stability under vertical load and preventing disconnection between components due to vertical load.

[0051] In this embodiment, the corner member 1, side member 2, and central connecting member 3 all have the same thickness, and the heights of the first oblique slot 11 and first oblique fixing block 12 are both greater than half the thickness of the corner member 1. This arrangement ensures a tight connection between the matching oblique slots and oblique fixing blocks.

[0052] In this embodiment, the corner members 1, side members 2 and central connecting member 3 are all symmetrical structures. This arrangement makes it unnecessary to distinguish between left and right when the members are connected, thereby improving the convenience of assembly.

[0053] In this embodiment, pre-set holes 4 are provided in the center of each of the corner member 1, side member 2, and central connecting member 3. This arrangement allows for the installation of vertical poles 6 for protection, eliminating the need for additional drilling holes in the steel structure 5 used for construction or construction. Specifically, the pre-set holes 4 serve as bolt holes, which improves connection stability and construction safety when installing the vertical poles 6.

[0054] In this embodiment, the corner members 1, side members 2, and central connecting member 3 are all made of metal. Specifically, the corner members 1 are suitable for installation at the corners of the steel structure 5, the side members 2 are suitable for installation at the edges of the steel structure 5, and the central connecting member 3 is suitable for installation in the middle of the steel structure 5.

[0055] In an alternative embodiment, the number of side members 2 and central connecting members can be increased according to demand to form grid platform frames of different shapes and sizes.

[0056] Specifically, the first embodiment is as follows Figure 6 As shown, the grid platform frame is composed of 4 corner members 1, 4 side members 2 and 1 central connecting member 3.

[0057] Specifically, the second embodiment is as follows Figure 7 As shown, the grid platform frame is composed of 4 corner members 1, 6 side members 2 and 2 central connecting members 3.

[0058] Specifically, the third embodiment is as follows Figure 8As shown, the grid platform frame is composed of 4 corner members 1, 8 side members 2 and 4 central connecting members 3.

[0059] In an alternative embodiment, when a grid platform frame with a larger size needs to be set up, it can be assembled by adding side members and central connecting members.

[0060] In summary, for this platform frame used in high-altitude steel structure construction, 4 side members 2 are respectively clamped at intervals between 4 corner members 1 to form a composite frame structure, and then connected to the side members 2 through the central connecting members 3 and installed in the middle of the frame structure, so as to form a grid platform frame in the shape of a Chinese character "tian", which is convenient to be laid on the steel structure 5 frame to form a support frame for the working platform. The connection method of clamping can make the structure easy to disassemble and install, and can be reused. The assembled platform frame in the shape of a Chinese character "tian" can directly lay materials such as wooden boards or steel笆片7 on the construction site that are convenient for walking on it, greatly improving the activity space. In this way, construction workers can directly carry out construction above the steel structure 5. The cooperative connection between the inclined slot and the inclined fixing block makes it necessary to insert and fit the corner member 1, the side member 2 and the central connecting member 3 from the side. This insertion method can convert the vertical force into a fastening force, and the greater the force, the tighter the connection, which can ensure the structural stability when vertically stressed. At the same time, this shaped structure can evenly disperse the force when in use. When subjected to an external force, each part works together to bear the force, avoiding stress concentration at a certain point or on a certain side, so as to maintain overall stability; the cross nodes of the horizontal and vertical members on the central connecting member 3 in the middle of the grid support structure in the shape of a Chinese character "tian" enhance the overall rigidity, enabling the platform frame to bear large vertical and horizontal loads. While carrying a large weight, it is not easy to deform and damage; at the same time, this framed platform frame can save the use of materials and reduce the construction cost while meeting the support requirements compared with other construction platform support frames.

[0061] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of this invention.
