Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to an assembled support platform for a scaffold in a multi-section square caisson. Background Art

[0002] A caisson is generally made into a shaft-shaped or rectangular structure on the ground. Then, with the maintenance of the well wall, the soil is continuously excavated from the well, allowing the caisson to gradually sink under its own weight. After reaching the predetermined design elevation, the bottom is sealed and the internal structure is constructed.

[0003] However, during the construction of cast-in-place reinforced concrete caissons, the inner scaffolding and formwork support system are generally dismantled due to the internal soil excavation. Before the construction of the next section of the caisson wall, the internal scaffolding body and support system are re-erected; when the caisson shaft is deep and requires multiple sections of construction, this link will be repeated many times. The use of welded triangular steel supports and on-site assembly of bulk materials not only has a long construction period, but also cannot provide the quality it deserves. In summary, there is still a lot of room for improvement in the existing scaffolding support structure in caissons. Therefore, it is necessary to provide a new type of scaffolding assembly platform for caissons. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a multi-section square caisson scaffolding assembly support platform, which includes a plurality of single-section square caisson scaffolding assembly platforms that can be detachably assembled together, and the single-section square caisson scaffolding assembly platform includes a support frame formed by a first support assembly unit and a second support assembly unit that are perpendicular to each other, wherein the first support assembly unit is connected and fixed to the embedded parts of the caisson wall through a supporting workpiece; the second support assembly unit is erected on the first support assembly unit, and the first support assembly unit and the second support assembly unit are connected and fixed by U-shaped fasteners; the first support assembly unit includes a pair of main channel steels and a first support assembly connector connected and fixed to the pair of main channel steels; the second support assembly unit has the same structure as the first support assembly unit.

[0005] As an improvement, the second support assembly unit includes a pair of secondary channel steels and a second support assembly connector connected and fixed to the pair of secondary channel steels.

[0006] As an improvement, the first support assembly unit is used as a main beam, and two of the first support assembly units are spaced apart along the length direction of the caisson to form a first operating channel frame, and a steel plate is fixed on the first operating frame to form a first operating channel.

[0007] As an improvement, the second support assembly unit is used as a secondary beam, and two of the second support assembly units are spaced apart along the width direction of the caisson to form a second operating channel frame, and a steel plate is fixed on the second operating channel frame to form a second operating channel.

[0008] As an improvement, the supporting workpiece and the embedded part are fixed by full-angle welding.

[0009] As an improvement, the supporting workpiece is U-shaped; the channel steel of the first supporting assembly unit is placed on the supporting workpiece.

[0010] As an improvement, the first supporting assembly connecting member includes a plurality of first bolts, first nuts matched with the first bolts, and first steel pipes for fitting the first bolts.

[0011] As an improvement, the first support assembly unit is further provided with a U-shaped component connection hole and a lifting hole.

[0012] As an improvement, the model of the main channel steel is larger than the model of the secondary channel steel.

[0013] As an improvement, the length of the first support assembly unit is less than or equal to the length of the second support assembly unit.

[0024] The present invention is further described in detail below through specific implementations in combination with the accompanying drawings. The purpose of providing the following specific implementations is to facilitate a clearer and more thorough understanding of the disclosure of the present invention, wherein the left and right directions of the drawings are the horizontal directions, and the up and down directions of the drawings are the vertical directions.

[0025] The present invention proposes a multi-section square caisson internal scaffolding assembly support platform, which is formed by detachably assembling together a plurality of single-section square caisson internal scaffolding assembly platforms. The present invention is particularly suitable for square caissons with a relatively deep depth, such as square multi-section cast-in-place reinforced concrete caissons and similar shaft construction state designs. Figure 1 The schematic plan view of two parallel square caissons 10 is shown. The following is an example of a single square caisson 10 with a scaffolding assembly platform in a single caisson. The length of the square caisson 10 is 7760 mm and the width is 6500 mm (see Figure 2 ); the length direction of the square caisson 10 is the length direction, the width direction of the square caisson 10 is the width direction, the length direction side of the square caisson 10 is the long side, and the width direction side of the square caisson 10 is the short side.

[0026] like Figure 2 As shown, in this embodiment, a prefabricated support platform is provided inside the wall 8 of the square caisson 10, and the prefabricated support platform includes a support frame formed by a first support assembly unit 1 and a second support assembly unit 2 which are perpendicular to each other, wherein the first support assembly unit 2 is used as a main beam (i.e., as a main force-transmitting component), and the first support assembly unit 1 is connected and fixed to an embedded part 3 buried in the inner wall surface of the caisson wall 8 via a supporting workpiece 4; the second support assembly unit 2 is used as a secondary beam, and the second support assembly unit 2 is erected on the first support assembly unit 1, and the first support assembly unit 1 and the second support assembly unit 2 are connected and fixed via U-shaped fasteners 5 to form a whole. Figure 2It can be seen that in this embodiment, five first support assembly units 1 are arranged at intervals along the width direction of the square caisson 10, and five second support assembly units 2 are arranged at intervals along the length direction of the square caisson 10. The five first support assembly units 1 and the five second support assembly units 2 are connected and fixed to each other, and the first support assembly unit 1 is fixed to the embedded parts 3 in the inner wall surface of the caisson wall 8, thereby forming a single-section caisson internal scaffolding assembled support platform; the above-mentioned single-section caisson internal scaffolding assembled support platform can be used to form an operating platform by laying scaffolding boards during the dismantling process of the upper scaffolding; a rectangular ring operating platform frame surrounding the inner wall surface of the caisson is formed by multiple first support assembly units 1 and multiple second support assembly units 2 arranged vertically to each other.

[0027] like Figure 3 and Figure 4 As shown, the first support assembly unit 1 includes a pair of main channel steels 11 and a first support assembly connector 12 arranged between the pair of main channel steels 11. In this embodiment, the two main channel steels 11 are connected by a plurality of first bolts 121 and a plurality of first nuts 122 (in this embodiment, three first bolts 121 and three first nuts 122) matched with the first bolts 121. The outside of each of the plurality of first bolts 121 is covered with a first steel pipe 123 to form the first support assembly connector 12. The first steel pipe 123 can support the main channel steels 11 located on both sides of the steel pipe so that the two main channel steels 11 and the first support assembly connector 12 are connected and fixed in a tensioning and supporting manner. The first steel pipe 123 is also used to control the spacing between the two main channel steels 11. The main channel steel 11 includes a first web 111 and a web 111 located on the first web 11 1, the first upper flange 112 and the first lower flange 113 at both ends of the main channel steel 11 are both side plates extending horizontally outward from the first web 111; in this embodiment, a first support assembly unit 1 is arranged on the length midline of the square caisson, and four first support assembly units 1 are symmetrically arranged on the two short sides of the square caisson, and each short side is provided with two first support assembly units 1 arranged at intervals, for example, the interval is 1050mm, and the first steel plates 14 of corresponding sizes are laid on the above two first support assembly units 1, and the first steel plates 14 are fixed on the first upper flange 112 of the corresponding main channel steel 11 by spot welding. Therefore, the above four first support assembly units 1 form two first operation channels in the width direction of the caisson, and the first operation channels are used for construction personnel to stand or walk.

[0028] like Figure 5As shown, the second support assembly unit 2 includes a pair of secondary channel steels 21 and a second support assembly connector 22 arranged between the pair of secondary channel steels 21. In this embodiment, the two secondary channel steels 21 are connected and fixed by a plurality of second bolts 221 and a plurality of second nuts matched with the second bolts 221 (in this embodiment, two second bolts 221 and two second nuts 222). The outer side of each of the plurality of second bolts 221 is covered with a second steel pipe 223 to form a second support assembly connector 22. The second steel pipe 223 can support the secondary channel steels 21 located on both sides of the steel pipe so that the two secondary channel steels 21 and the second support assembly connector 22 are connected and fixed in a tensioning and supporting manner; the secondary channel steel 21 includes a second web and second webs at both ends of the second webs. Two upper flanges and a second lower flange, the second upper flange and the second lower flange are both side plates extending horizontally outward from the second web; in the present embodiment, a second support assembly unit 2 is arranged on the width midline of the square caisson, and four second support assembly units 2 are symmetrically arranged on the two long sides of the square caisson, and each long side is provided with two second support assembly units 2 arranged at intervals, for example, the spacing is 1050mm, and second steel plates 15 of corresponding sizes are laid on the above-mentioned two second support assembly units 2, and the second steel plates 15 are fixed on the second upper flange of the corresponding secondary channel steel 21 by spot welding. Thus, the above-mentioned four second support assembly units 2 form two second operating channels in the length direction of the caisson, and the second operating channels are used for construction personnel to stand or walk.

[0029] In addition, U-shaped fastener connection holes and lifting holes are provided at corresponding positions of the first supporting assembly unit 1 .

[0030] Furthermore, if Figure 6 , Figure 7 and Figure 8 As shown, the first support assembly unit 1 is directly placed on the supporting workpiece 4 without the need for other fixing components. The supporting workpiece 4 is fixed to the embedded plate 31 of the embedded part 3 in the caisson; the second support assembly unit 2 is fixedly connected to the first support assembly unit 1 by a U-shaped fastener 5, thereby completing the assembly of the support frame of the scaffolding assembled support platform in a single-section square caisson.

[0031] It should be noted that the first support assembly unit 1 and the second support assembly unit 2 can be assembled in a factory or at a construction site; the main channel steel 11 and the secondary channel steel 21 are preferably channel steels of different specifications, but can also be the same channel steel; the above is only for illustration and cannot be understood as a limitation of the present invention. Furthermore, the length of the first support assembly unit 1 is less than or equal to the length of the second support assembly unit 2. The first support assembly unit 1 and the second support assembly unit 2 of the present invention can determine the size and model of the components therein according to the actual length and width of the caisson, and the number of sections of the scaffolding assembled support platform in the square caisson can be determined according to the actual depth of the caisson.

[0032] Compared with the prior art, the multi-section square caisson scaffolding assembly support platform of the present invention is detachable and easy to assemble on site, which reduces the workload of on-site operations, saves operation time, and improves work efficiency; the force-bearing structure can be reused for multiple cycles, saving materials; the force-bearing components can be placed sideways, do not occupy too much on-site space, and the on-site civilized construction meets the requirements; the structural system is safe and reliable, ensuring construction safety. In addition, the caisson scaffolding assembly support platform of the present invention is widely used, for example, it can be used as an upper scaffolding body, a support system, a construction operation force-bearing structure, and an operation platform.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
