Description

Technical Field

[0001] The present invention relates to the technical field of temporary facilities for building construction, and more specifically, to a prefabricated temporary operation platform for installing a space grid structure and its usage method. Background Art

[0002] A space grid structure (such as a space truss structure, a grid structure, etc.) is a complex space bar system structure, in which numerous bars are arranged in multiple directions according to specific geometric rules and are connected through nodes to form a reticulated structure system with spatial stiffness. Such structures are widely used in large-span buildings, stadiums, exhibition centers and other fields, and are favored because of their good mechanical properties and high space utilization efficiency.

[0003] During the installation construction process of a space grid structure, due to the dense internal bars and complex structure, the operating space between the bars is extremely limited. Traditional floor-type construction operation platforms are difficult to adapt to the narrow operating space inside the space grid structure because of their large volume and poor flexibility, and cannot provide an effective working platform for construction workers, thus restricting the smooth progress of construction operations such as installation, welding, and inspection, and seriously affecting construction efficiency and quality.

[0004] In addition, traditional floor-type operation platforms require stable ground support, while in the construction of space grid structures, it is often difficult to provide stable support conditions due to the dynamics and space limitations of the construction process. This not only increases the construction difficulty, but also may lead to safety accidents, further increasing the construction cost.

[0005] Therefore, in view of the construction characteristics of space grid structures, it is particularly urgent to develop a temporary operation platform with high adaptability, flexibility and safety. Such an operation platform should be able to make full use of the bars of the space grid structure itself as supports to achieve rapid assembly and disassembly, and at the same time have adjustability to adapt to different construction stages and space requirements, so as to effectively improve construction efficiency, ensure construction safety, reduce construction costs, and improve economic and social benefits. Summary of the Invention

[0006] The present invention aims to provide a prefabricated temporary operation platform for installing a space grid structure and its usage method to solve the problem of the difficulty in setting up traditional floor-type operation platforms inside complex space grid structures. This platform can be widely used in the installation construction of various space grid structures, can significantly improve construction efficiency and safety, and at the same time reduce construction costs and labor intensity.

[0007] To achieve the object of the present invention, the technical solution adopted is as follows: an assembled temporary operation platform for the installation of a space grid structure, including a C-shaped rod whose two ends can be respectively hung on two adjacent diagonal web members of the space grid structure. Two horizontally arranged platform tie rods are installed on the C-shaped rod. The other ends of the two platform tie rods are jointly installed with a connecting rod. The connecting rod, the platform tie rods, and the C-shaped rod jointly enclose a horizontal temporary operation platform, and a platform grille is installed in the temporary operation platform; telescopic adjustable support rods are further connected between the two ends of the connecting rod and the C-shaped rod, and the C-shaped rod, the telescopic adjustable support rods, and the platform tie rods form a triangular support structure.

[0008] Further, the C-shaped rod has a middle straight section, a semi-circular section, and end straight sections. The semi-circular sections are located at both ends of the middle straight section, and the end straight sections are located at the ends of the semi-circular sections away from the middle straight section. The platform tie rods are connected to the middle straight section.

[0009] Further, sleeve A is also provided at both ends of the platform tie rod, and the two sleeve As are respectively sleeved on the middle straight section of the C-shaped rod and the connecting rod.

[0010] Further, the platform grille includes a plurality of edge sealing rods arranged at intervals along the axis direction of the platform tie rod and a number of cross rods connected between two adjacent edge sealing rods, and both ends of the edge sealing rods are respectively connected to the connecting rod and the middle straight section of the C-shaped rod.

[0011] Further, sleeve B is provided at one end of the edge sealing rod, and a semi-circular tile plate is provided at the other end of the edge sealing rod. Sleeve B is sleeved on the connecting rod, and the semi-circular tile plate is clamped on the middle straight section of the C-shaped rod.

[0012] Further, sleeve C is provided at both ends of the telescopic adjustable support rod. Sleeve C at one end is sleeved on the end straight section of the C-shaped rod, and sleeve C at the other end is sleeved on the connecting rod.

[0013] Further, an adjusting bolt is provided on the rod body of the telescopic adjustable support rod, and by screwing the adjusting bolt, the telescopic adjustable support rod can be freely telescoped.

[0014] Further, head plates are also provided at both ends of the connecting rod. At least one head plate is bolted to the connecting rod, and the diameter of the head plate is larger than the diameter of the connecting rod.

[0015] The usage method of the assembled temporary operation platform for the installation of a space grid structure includes the following steps: Step 1: In the space grid structure, determine the position where the temporary operation platform needs to be set, and select two adjacent diagonal web members connected to the same upper chord node near it. These two diagonal web members should meet the following conditions: the specifications and diameters are the same or differ little, are in a herringbone shape and are in the same plane; Step 2: Vertically hang the C-shaped rod pre-fitted with two platform tie rods from top to bottom on the two diagonal web members. During this operation, slowly lower the C-shaped rod until the semi-circular segments at both ends of the C-shaped rod are in close contact with the two diagonal web members, and then adjust the attitude of the C-shaped rod so that the middle straight segment of the C-shaped rod reaches a horizontal state; Step 3: Clamp the two telescopic adjustable support rods on the end straight segments at both ends of the C-shaped rod respectively. After the clamping is completed, adjust the length of the telescopic adjustable support rods according to the actual installation requirements, and move the two platform tie rods and the two telescopic adjustable support rods closer to and against the two diagonal web members respectively; Step 4: Steadily place the platform grille between two adjacent platform tie rods, and ensure that the semi-circular tile plate on one side of the platform grille is accurately clamped on the middle straight segment of the C-shaped rod when placing; Step 5: Take the connecting rod and pass the connecting rod through the telescopic adjustable support rod, the platform tie rod, the platform grille, the platform tie rod on the other side, and the telescopic adjustable support rod on the other side in sequence, so as to connect all components into a whole and construct a stable temporary operation platform; Step 6: Fine-tune the length of the telescopic adjustable support rod again to fine-tune the attitude of the temporary operation platform and ensure that the temporary operation platform is in a horizontal state.

[0020] The present invention will be further described in detail below with reference to the attached drawings and implementation manners. It can be understood that the specific implementation manners described herein are only used to explain the relevant content and do not limit the present invention. Additionally, it should be noted that for the sake of description, only the parts related to the present invention are shown in the attached drawings.

[0021] It should be noted that, without conflict, the implementation manners in the present invention and the features in the implementation manners can be combined with each other. The present invention will be described in detail below with reference to the attached drawings and implementation manners.

[0022] As Figures 1 to 5As shown in the figure, a prefabricated temporary operation platform for installing a space grid structure provided by the present invention includes a C-shaped rod 1, a platform tie rod 2, a telescopic adjustable support rod 3, a platform grille 4, and a connecting rod 5. The C-shaped rod 1 is bent and processed from a circular pipe or round steel, and its length depends on the length of the prefabricated temporary operation platform. The C-shaped rod 1 has a middle straight section 1.3, a semi-circular section 1.1, and an end straight section 1.2. The end straight section 1.2 is parallel to the middle straight section 1.3. There are two semi-circular sections 1.1 and two end straight sections 1.2. The two semi-circular sections 1.1 are located at both ends of the middle straight section 1.3, and the two end straight sections 1.2 are respectively located at one end of the two semi-circular sections 1.1 away from the middle straight section 1.3. In this embodiment, the diameter of the semi-circular section 1.1 on the C-shaped rod 1 is slightly larger than the diameter of the diagonal web member to which it is attached.

[0023] When the C-shaped rod 1 is in use, the semi-circular sections 1.1 at both ends of the C-shaped rod 1 are hung on two adjacent diagonal web members in the space grid structure. At this time, the middle straight section 1.3 and the end straight section 1.2 of the C-shaped rod 1 are located on opposite sides of the diagonal web member. Since two adjacent diagonal web members are in a "V" shape, after the C-shaped rod 1 is hung on two adjacent diagonal web members, the C-shaped rod 1 cannot move downward any further after descending a certain distance on the two adjacent diagonal web members.

[0024] As Figure 2 shown in the figure, the platform tie rod 2 is made of round steel. Both ends of the platform tie rod 2 have sleeve A 2.1, and the sleeve A 2.1 is made of a circular pipe. The length of the platform tie rod 2 depends on the width of the prefabricated temporary operation platform. When the platform tie rod 2 is installed, the sleeve A 2.1 at one end of the platform tie rod 2 is sleeved on the middle straight section 1.3 of the C-shaped rod 1, and the inner diameter of the sleeve A 2.1 has a clearance fit with the diameter of the C-shaped rod 1; the sleeve A 2.1 at the other end of the platform tie rod 2 is sleeved on the connecting rod 5, and the inner diameter of this sleeve A 2.1 has a clearance fit with the diameter of the connecting rod 5.

[0025] As Figure 3 It should be noted that in the translation of the description of the shape relationship in the original text, there may be some inaccuracies in the expression. For example, the description of the "herringbone" shape of the two adjacent diagonal web members in the original text may be more accurately described as "V" shape in the translation to better conform to the geometric relationship described. You can adjust it according to the actual situation.As shown in the figure, the telescopic adjusting support rod 3 is made of a circular tube, and the telescopic adjusting support rod 3 includes a rod body 3.2 and an adjusting bolt 3.3. The central axis of the adjusting bolt 3.3 is on the same straight line as the central axis of the rod body 3.2. The rod body 3.2 is divided into two sections, and the adjusting bolt 3.3 is located between the two sections of the rod body 3.2. Both connections between the two sections of the rod body 3.2 and the adjusting bolt 3.3 have internal threads, and external threads matching the internal threads are provided at both ends of the adjusting bolt 3.3. When the adjusting bolt 3.3 rotates, the two sections of the rod body 3.2 approach or move away from each other, so that the rod body 3.2 can be extended or shortened, and the length of the telescopic adjusting support rod 3 is adjusted. To facilitate the connection of the telescopic adjusting support rod 3 with the connecting rod 5 and the C-shaped rod 1, a sleeve C3.1 is provided at one end of the rod body 3.2 away from the adjusting bolt 3.3. The inner diameter of one sleeve C3.1 is slightly larger than the diameter of the straight section 1.2 at the upper end of the C-shaped rod 1, and the inner diameter of the other sleeve C3.1 is slightly larger than the diameter of the connecting rod 5. When the telescopic adjusting support rod 3 is installed, one sleeve C3.1 is sleeved on the straight section 1.2 at the end of the C-shaped rod 1, and the other sleeve C3.1 is sleeved on the connecting rod 5. By turning the adjusting bolt 3.3, the length of the telescopic adjusting support rod 3 is adjusted, so that the platform grating 4 is kept horizontal.

[0026] To facilitate the rotation of the adjusting bolt 3.3, a nut can also be welded at the middle position of the adjusting bolt 3.3. When the adjusting bolt 3.3 needs to be rotated, the nut can be directly turned. When the nut rotates, it drives the adjusting bolt 3.3 to rotate, so that the two rod bodies 3.2 approach or move away from each other, and the telescopic adjusting support rod 3 realizes telescoping.

[0027] As Figure 4 shown in the figure, the platform grating 4 is made of a circular tube and round steel, and the platform grating 4 is rectangular. The length of the platform grating 4 is adapted to the distance between two adjacent platform tie rods 2, and the length of the platform grating 4 is adapted to the distance between the middle straight section 1.3 on the C-shaped rod 1 and the connecting rod 5. When the platform grating 4 is installed, it is located in the temporary operation platform jointly surrounded by the middle straight section 1.3 on the C-shaped rod 1, the two platform tie rods 2, and the connecting rod 5. The temporary operation platform is horizontal, and the platform grating 4 is horizontal in the temporary operation platform after installation. The platform grating 4 includes edge sealing rods 4.1 located inside the two platform tie rods 2 and a plurality of cross bars 4.4 connected between the two edge sealing rods 4.1. The plurality of cross bars 4.4 are evenly spaced along the axis direction of the edge sealing rods 4.1.

[0028] For the convenience of installing the platform grille 4, one end of the edge-sealing rod 4.1 close to the C-shaped rod 1 is also provided with a semi-circular tile plate 4.3. The inner diameter of the semi-circular tile plate 4.3 is adapted to the diameter of the middle straight section 1.3 on the C-shaped rod 1. When the platform grille 4 is installed, the semi-circular tile plate 4.3 is clamped on the middle straight section 1.3 of the C-shaped rod 1. At the same time, one end of the edge-sealing rod 4.1 close to the connecting rod 5 is also provided with a sleeve B4.2. The inner diameter of the sleeve B4.2 is slightly larger than the diameter of the connecting rod 5. When the platform grille 4 is installed, the sleeve B4.2 is sleeved on the connecting rod 5.

[0029] As Figure 5 shown, the connecting rod 5 is made of round steel or round pipe. The connecting rod 5 is used to connect the platform tie rod 2, the telescopic adjustable support rod 3 and the platform grille 4 into a whole, and cooperate with the connection of the platform tie rod 2, the telescopic adjustable support rod 3, the platform grille 4 and the C-shaped rod 1 to form a complete temporary operation platform. One end of the connecting rod 5 is fixed with a head plate 5.2. The diameter of the head plate 5.2 is larger than the inner diameters of the sleeve A2.1, the sleeve B4.2 and the sleeve C3.1, that is, the diameter of the head plate 5.2 is larger than the diameter of the connecting rod 5, so as to prevent the sleeve A2.1, the sleeve B4.2 and the sleeve C3.1 from sliding out from one end of the connecting rod 5. At the same time, an internal screw hole 5.1 is opened on the end face of the other end of the connecting rod 5, and another head plate 5.2 is fixed on the end face of the connecting rod 5 through a bolt 5.3.

[0030] Of course, in this embodiment, internal screw holes 5.1 can also be opened at both ends of the connecting rod 5, so that the two head plates 5.2 are both fixed on the end face of the connecting rod 5 through bolts 5.3.

[0031] Based on the above-mentioned prefabricated temporary operation platform for installing a space grid structure, the present embodiment also provides a method for using the same, including the following steps: Step 1: As Figure 6 shown, in the space grid structure, determine the position where the temporary operation platform needs to be set, and select two adjacent diagonal web members connected to the same upper chord node nearby. These two diagonal web members should meet the following conditions: the same or slightly different in specification diameter, in a herringbone shape and in the same plane. At the same time, the sleeves A2.1 on the two platform tie rods 2 are sleeved on the middle straight section 1.3 of the C-shaped rod 1.

[0032] Step 2: Preliminary fixation and leveling As Figure 7As shown, the combination of two platform tie rods 2 and C-shaped rod 1 is vertically hung from top to bottom on two adjacent diagonal web bars, ensuring that the semicircular section 1.1 of the C-shaped rod 1 can fit closely to the outside of the diagonal web bar, providing a stable support foundation for the subsequent temporary operating platform. At the same time, the C-shaped rod 1 is moved and deflected to be in a suitable position between the two diagonal web bars and preliminarily adjusted to make the middle straight section of the C-shaped rod 1 reach a horizontal state.

[0033] Step 3: Install the telescopic adjustment support rod 3 like Figure 8 As shown, the sleeve C3.1 at one end of the telescopic adjustable support rod 3 is sleeved on the two straight segments at both ends of the C-shaped rod 1, and by turning the adjusting bolt 3.3, the two sections of the rod body 3.2 are moved closer to each other or farther away from each other, so that the rod body 3.2 is extended or shortened as a whole, so that the telescopic adjustable support rod 3 can be extended and retracted, and its length can be accurately adjusted. The sliding platform pull rod 2 and the telescopic adjustable support rod 3 are gradually brought close to the two oblique belly rods.

[0034] Step 4: Laying the platform grid 4 like Figure 9 As shown, the platform grille 4 is smoothly placed between the two platform tie rods 2 in the horizontal direction, ensuring that the sleeve B4.2 on the edge bar 4.1 of the platform grille 4 can be smoothly sleeved on the connecting rod 5, and at the same time, the semicircular tile plate 4.3 at the other end of the edge bar 4.1 is accurately clamped on the middle straight section 1.3 of the C-shaped rod 1 to achieve a stable connection between the platform grille 4 and the C-shaped rod 1. During the placement of the platform grille 4, pay attention to maintaining its horizontality to ensure the safety and comfort of the operator when working on the platform.

[0035] Step 5: Install the connecting rod 5 and connect the components in series like Figure 10 As shown, the end of the connecting rod 5 without the head plate 5.2 is passed through the sleeve C3.1 on the telescopic adjustable support rod 3, the sleeve A2.1 of the platform tie rod 2, the sleeve B4.2 of the platform grille 4 and the sleeve A2.1 on the platform tie rod 2 on the other side and the sleeve C3.1 of the telescopic adjustable support rod 3 on the other side in sequence, and the platform tie rod 2, the telescopic adjustable support rod 3 and the platform grille 4 are connected in series into a whole through the connecting rod 5 to form a stable temporary operating platform.

[0036] Step 6: Complete installation and adjustment like Figure 11 As shown, the basic installation work of the temporary operating platform is now completed. However, in order to ensure the safety and comfort of the temporary operating platform during actual use, the length of the telescopic adjustment support rod 3 can be adjusted by screwing the adjustment bolt 3.3 to fine-tune the level of the temporary operating platform so that it fully meets the requirements of the construction site and provides a safe and reliable temporary operating environment for operators.

[0037] By assembling and installing the temporary operation platform by adopting the above usage method, not only can the firmness, stability and levelness of the temporary operation platform be ensured, but also the safety and operation requirements of construction workers for various operations inside the space grid structure can be met; meanwhile, during the construction process, the length of the telescopic adjusting support rod 3 can be adjusted at any time according to needs to adapt to different construction conditions and requirements, ensuring that the temporary operation platform is always in the best working state.

[0038] Those skilled in the art should understand that the above embodiments are only for clearly explaining the present invention and not for limiting the scope of the present invention. For those skilled in the art, other changes or modifications can be made on the basis of the above disclosure, and these changes or modifications are still within the scope of the present invention.
