[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0034] The first aspect of the present invention provides a pedestrian walkway platform support. Figure 1 and Figure 2 As shown, it includes a vertical pole 1 and a base bracket 2;

[0035] The vertical pole 1 is connected with a support assembly 3 for supporting the guardrail crossbar 6 and a kick plate stopper 4 movably connected to the vertical pole 1 along the extension direction of the vertical pole 1;

[0036] The outer end of the base bracket 2 is connected to the bottom end of the vertical pole 1, and the inner end of the base bracket 2 has a connecting end 211 for connecting to the large template I-beam 8 and a supporting end 2221 supported on the large template I-beam 8. The base bracket 2 between the connecting end 211 and the outer end has a top surface 212 for laying the pedestrian walkway slab 9, and the supporting end 2221 is located on the side of the connecting end 211 away from the top surface 212.

[0037] by Figure 2 Take the following as an example to explain the usage status of the above-mentioned pedestrian walkway platform bracket in detail:

[0038] During installation, the connecting end 211 is connected to the web of the large formwork I-beam 8, and the supporting end 2221 is supported on the wing plate of the large formwork I-beam 8 from the bottom of the connecting end 211. After multiple pedestrian walkway platform brackets are installed side by side and at intervals on different large formwork I-beams 8, the guardrail crossbar 6 can be placed on the supporting assembly 3 to play a protective role, the kick plate 7 can be placed on the right side of the vertical pole 1 and limited by the kick plate limiter 4, and the pedestrian walkway board 9 can also be laid on the top surface 212 of the base bracket 2 for people to walk on, thus forming a stable pedestrian walkway platform.

[0039] During use, since the connecting end 211 is connected to the web of the large template I-beam 8, and the supporting end 2221 is supported on the wing plate of the large template I-beam 8 from the bottom of the connecting end 211, the base bracket 2 can stably support the pedestrian walkway plate 9 when the pedestrian walkway plate 9 is under pressure, thereby preventing the base bracket 2 from rotating relative to the large template I-beam 8.

[0040] The above-mentioned pedestrian walkway platform bracket has a simple structure and stable support. A single pedestrian walkway platform bracket can be independently disassembled and assembled, which is convenient for construction and maintenance and highly economical. In addition, before the large template is hoisted into place, each pedestrian walkway platform bracket can be installed on the corresponding large template I-beam 8 on the ground, and then hoisted into place together with the template. There is no need to install the pedestrian walkway platform bracket at a high place, which effectively improves construction efficiency and reduces safety risks.

[0041] The support assembly 3 may include one support member, or may include two, three, four or more support members.

[0042] In some embodiments, Figure 1 As shown, the support assembly 3 includes a first support member 31 and a second support member 32 distributed along the extension direction of the vertical pole 1, a slot for supporting the guardrail cross bar 6 of the upper layer is formed between the first support member 31 and the vertical pole 1, and a slot for supporting the guardrail cross bar 6 of the lower layer is formed between the second support member 32 and the vertical pole 1.

[0043] The above arrangement enables the support assembly 3 to support the upper and lower guardrail crossbars 6 at the same time, thereby improving the safety of the pedestrian walkway platform.

[0044] In some embodiments, Figure 1 As shown, the first support member 31 and the second support member 32 are both bent into an "L" shape, one end of the first support member 31 and the second support member 32 are connected to the vertical pole 1, and the other end is bent in a direction away from the base bracket 2, thereby forming a slot between the vertical pole 1 that can support the guardrail cross bar 6.

[0045] The first support member 31 and the second support member 32 have simple structures and can be connected to the upright pole 1 by welding.

[0046] In some embodiments, Figure 1 As shown, the kick plate limiter 4 includes a sliding sleeve 41 and a limiting plate 42. The sliding sleeve 41 is sleeved on the vertical pole 1 and slides with the vertical pole 1 along the extension direction of the vertical pole 1, so as to be able to adapt to kick plates 7 of different heights. One end of the limiting plate 42 is connected to the sliding sleeve 41, and the other end forms a limiting groove with the vertical pole 1 for limiting the top end of the kick plate 7.

[0047] Specifically, Figure 2As shown, the kick plate limiter 4 is located below the support assembly 3. The kick plate limiter 4 can overlap the kick plate 7 under the action of its own gravity, and the limiter plate 42 cooperates with the side of the kick plate 7 to prevent the kick plate 7 from tilting.

[0048] In some embodiments, Figure 1 As shown, the limiting plate 42 is bent into an "L" shape; one end of the limiting plate 42 is connected to the sliding sleeve 41; the other end of the limiting plate 42 is bent toward the direction close to the base bracket 2, so that the end can be against the side of the kick plate 7.

[0049] The kick plate limiter 4 has a simple structure and does not need to be connected to the kick plate 7 by connecting members such as screws, which is convenient for construction personnel.

[0050] In some embodiments, Figure 1 As shown, the connecting end 211 and the supporting end 2221 both include a U-shaped clip for clipping onto the wing plate of the large template I-beam 8, and in each U-shaped clip, the oppositely arranged side walls are provided with connecting holes for inserting the connecting piece 5.

[0051] When in use, first clamp the U-shaped clamping parts in the connection end 211 and the support end 2221 on the wing plate of the large template I-beam 8, and then pass the connection part 5 through the connection hole of the U-shaped clamping part in the connection end 211 and the connection hole on the web of the large template I-beam 8 to connect the connection end 211 to the web of the large template I-beam 8. The U-shaped clamping part in the support end 2221 can be connected to the web of the large template I-beam 8 through the connection part 5, or it can be connected to the web of the large template I-beam 8 without the connection part 5, and only abut against the wing plate of the large template I-beam 8.

[0052] In at least one embodiment, the U-shaped clip in the support end 2221 is also connected to the web of the large template I-beam 8 through the connecting piece 5, further ensuring the installation stability of the pedestrian walkway platform bracket.

[0053] It should be noted that, along the extension direction of the large template I-beam 8, a plurality of connection holes are provided on the large template I-beam 8, and the connector 5 can pass through any of the connection holes to be connected to the U-shaped clip, so as to facilitate the adjustment of the height of the U-shaped clip.

[0054] The connecting member 5 may include a bolt and a locking nut matched with the bolt.

[0055] In some embodiments, Figure 1 As shown, the base support 2 includes a supporting beam 21 and a support beam 22, wherein:

[0056] The supporting beam 21 is perpendicular to the vertical pole 1, the outer end of the supporting beam 21 is connected to the bottom end of the vertical pole 1, the inner end of the supporting beam 21 is a connecting end 211, the inner end of the supporting beam 21 is connected with a U-shaped clamping piece, and the supporting beam 21 has a top surface 212;

[0057] The support beam 22 is bent, and the outer end of the support beam 22 is connected to the bottom end of the vertical pole 1 at an angle and extends in a direction away from the top surface 212. The inner end of the support beam 22 is the support end 2221, and the inner end of the support beam 22 is connected to a U-shaped clamping piece.

[0058] It can be understood that the above-mentioned "outer end" is the end of the pedestrian walkway platform bracket that is away from the large template I-beam 8 when it is in the installed state, and the above-mentioned "inner end" is the end of the pedestrian walkway platform bracket that is close to the large template I-beam 8 when it is in the installed state.

[0059] The support beam 22 is bent so as to support the upright pole 1 more stably and ensure the stability of the pedestrian walkway platform.

[0060] In at least one embodiment, the upright pole 1 and the support beam 22 are of an integrated structure.

[0061] In some embodiments, Figure 1 As shown, the support beam 22 includes an inclined portion 221 and a straight portion 222, one end of the inclined portion 221 is connected to the bottom end of the upright 1, the inclined portion 221 is arranged at an angle with the upright 1 and extends in a direction away from the top surface 212, the other end of the inclined portion 221 is connected to one end of the straight portion 222, the straight portion 222 is parallel to the supporting beam 21, and the other end of the straight portion 222 is a supporting end 2221, that is, the other end of the straight portion 222 is connected to a U-shaped clip.

[0062] Compared with the straight extension of the support beam 22 , the bending extension of the support beam 22 is more convenient for connecting the reinforcing beam 23 between the support beam 22 and the supporting beam 21 , and is convenient for the processing of the pedestrian walkway platform bracket.

[0063] Based on the above embodiments, Figure 1 As shown, the base bracket 2 also includes a reinforcing beam 23, one end of which can be welded to the supporting beam 21, and the other end can be welded to the straight portion 222. An inverted right-angled trapezoidal space is enclosed between the reinforcing beam 23, the supporting beam 21, the inclined portion 221 and the straight portion 222.

[0064] The upright pole 1, the supporting beam 21, the support beam 22 and the reinforcing beam 23 can all be made of hollow square steel to ensure the strength of the pedestrian walkway platform support, have good stability, and at the same time reduce the weight of the pedestrian walkway platform support.

[0065] Specifically, the side length of the hollow square steel may be 50 mm.

[0066] In summary, the pedestrian walkway platform bracket provided in the above embodiments has the following advantages: 1. Simple structure, easy to obtain materials and easy to process and manufacture, saving material and construction costs; 2. Stable structure, able to stably support the pedestrian walkway board 9, ensuring the flatness of the pedestrian walkway board 9, and the pedestrian walkway board 9 is comfortable and safe to walk on; 3. It has excellent properties such as light weight, high strength, and corrosion resistance; 4. Convenient transportation, construction and maintenance, improve construction efficiency, save materials, labor, machinery and maintenance costs, and ensure quality and safety.

[0067] The embodiment of the second aspect of the utility model is to provide a bracket assembly, and the bracket assembly provided by the embodiment of the second aspect of the utility model includes a plurality of the above-mentioned pedestrian walkway platform brackets, and the plurality of pedestrian walkway platform brackets are connected side by side and at intervals on a row of large template I-beams 8.

[0068] During construction, on the ground, multiple large template I-beams 8 are arranged parallel to each other, each pedestrian walkway platform bracket is installed on a different large template I-beam 8, and adjacent pedestrian walkway platform brackets are arranged at equal intervals. After the pedestrian walkway platform bracket is installed, it is hoisted into place together with the template. After it is in place, the large template I-beams 8 extend vertically, and each pedestrian walkway platform bracket is at the same height. Personnel can install guardrail cross bars 6, kick plates 7 and pedestrian walkway boards 9 on the pedestrian walkway platform brackets.

[0069] The bracket assembly provided in the second aspect of the utility model has the pedestrian walkway platform bracket provided in the embodiment of the first aspect of the utility model, and thus has all the beneficial effects of the pedestrian walkway platform bracket provided in the embodiment of the first aspect of the utility model.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
