Description

Technical Field

[0001] This invention relates to scaffolding for steel structure construction, specifically a high-safety scaffolding for steel structure construction, which can effectively adapt to different installation ground conditions and effectively ensure the support stability during use, thereby ensuring construction safety. Background Technology

[0002] During steel structure construction, working at heights is often required, hence the widespread use of scaffolding. Because steel structure construction involves relatively high heights and requires relatively wide work areas, existing scaffolding for steel structure construction is also relatively tall, and the area of ​​the platform for work positions is relatively large. This poses a significant challenge to the stability of the scaffolding used for supporting steel structure construction.

[0003] To improve the stability of scaffolding used in steel structure construction, the current practice is to increase the support area of ​​the scaffolding's uprights, thus increasing their contact surface with the ground. However, due to the varying ground structures at steel structure construction sites—not all are concrete, some are soil with insufficient flatness—increasing the support area of ​​the uprights cannot effectively create sufficient contact with the ground, resulting in limited improvement in stability. Most importantly, for construction sites with walls, increasing the support area of ​​the uprights leads to a greater distance between the scaffolding and the wall, which is unacceptable for steel structure construction.

[0004] Therefore, the research objective of this invention is to design a high-safety scaffold for steel structure construction that can effectively adjust the support method according to the characteristics of concrete and soil surfaces without excessively increasing the support area of ​​the support columns, so as to achieve high stability of support under different ground conditions and thus improve construction safety and adaptability. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a high-safety scaffold for steel structure construction, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this invention is: A high-safety scaffolding for steel structure construction includes: The scaffold body includes several support columns and horizontal connecting rods for connecting the several support columns into a whole. Construction tread assembly is provided on the support columns. The support assembly includes a limiting base fixed to the bottom end of the support column. The top inner side of the limiting base is provided with a corresponding inner groove in a ring shape. The top of the limiting base is also provided with a recessed stepped surface that matches the inner groove. The outer side of the limiting base is provided with a plurality of horizontal limiting holes with their inner ends connected to the inner groove at equal angles. The bottom side of the limiting base is provided with a plurality of vertical limiting holes with their top ends connected to the inner groove at equal angles. The limiting assembly includes several swing-type limiting sleeves that can be swingably installed in the inner groove of the limiting base, and a tightening sleeve that can be lifted and lowered on the support column on the upper side of the limiting base. When the swing-type limiting sleeve swings upward to abut against the outer wall of the inner groove, a skewer with its bottom end inserted below the ground is installed between the swing-type limiting sleeve and the vertical limiting hole. The upper part of the skewer is provided with a support seat that is locked on the concave step surface. The tightening sleeve moves down to abut against the inner side of the swing-type limiting sleeve. When the swing-type limiting sleeve swings downward to abut against the bottom side of the inner groove, the side of the skewer without the support seat is inserted into the swing-type limiting sleeve and the horizontal limiting hole. The side of the skewer with the support seat is located on the outer side of the limiting base. The support seat cooperates with the limiting base to support the ground. The tightening sleeve moves down to abut against the upper side of the swing-type limiting sleeve.

[0007] A corresponding clamping block is fixedly connected to the tightening sleeve. When the tightening sleeve moves downward and forms abutment and fixation on the inner side of the swing limiting sleeve, the clamping block presses against the support seat.

[0008] The clamping block is provided with a corresponding limiting threaded hole, and the swing limiting sleeve and the insert are respectively provided with limiting insertion holes adapted to the limiting thread. When the clamping sleeve moves down to form an abutment and fixation on the upper side of the swing limiting sleeve, the clamping block is located above the swing limiting sleeve, and a limiting bolt with the end of the rod inserted into the limiting insertion hole of the swing limiting sleeve and the insert is fixedly screwed into the limiting threaded hole.

[0009] The support base is arranged in an L-shaped plate shape. When the support base and the limiting base cooperate to support the ground, the bottom surface of the support base is fixedly abutting against the ground.

[0010] The pedal assembly includes a transfer pedal located in the middle of the support column and a set of construction pedals disposed on the upper part of the support column. A lower climbing ladder located on the outside of the support column is fixedly connected between the support columns below the transfer pedal, and an upper climbing ladder located on the inside of the support column and extending to the set of construction pedals is fixedly connected between the support columns above the transfer pedal.

[0011] In one set of construction treads, the front side of one construction tread extends to the outside of the support column, and the rear side of the other construction tread extends to the outside of the support column.

[0012] The outer sides of the lower and upper climbing ladders are respectively fixed with corresponding ring-shaped protective fences.

[0013] Each of the construction treads and transfer treads is fixed with a corresponding protective railing.

[0014] The scaffold body is evenly provided with multiple reinforcing members for structural reinforcement of the supporting columns, horizontal connecting rods and tread assembly.

[0015] The tightening sleeve is installed on the support column on the upper side of the limiting base by means of threaded connection.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1) The support assembly of the present invention includes a limiting base fixed to the bottom end of the support column. The limiting base has an inner groove, a horizontal limiting hole, and a vertical limiting hole to facilitate the addition of the limiting assembly. The limiting assembly includes a swing limiting sleeve rotatably installed in the inner groove and a tightening sleeve that is liftably installed on the support column.

[0017] When the construction surface is soil, the swing limiting sleeve can be swung upwards to abut against the outer wall of the inner groove. Inserts with their bottom ends inserted below the ground are installed between the swing limiting sleeve and the vertical limiting hole. Then, the tightening sleeve is driven downwards to abut against the inner side of the swing limiting sleeve to form a stable limit on the swing limiting sleeve. This creates a stable connection between the insert and the limiting base. Under the overall support of the limiting base and the anchoring effect of the insert, the invention can be effectively used for high-stability support on soil surfaces.

[0018] When the construction surface is a hard concrete surface, the swing limiting sleeve can be swung downwards to abut against the bottom side of the inner groove. Then, one side of the insert is inserted into the swing limiting sleeve and the horizontal limiting hole, so that the side of the insert with the support seat is located on the outside of the limiting base. Then, the tightening sleeve is driven down to abut against the upper side of the swing limiting sleeve to form a stable limit on the tightening sleeve, thereby forming a stable connection between the insert and the limiting base. With the cooperation of the support seat and the limiting base, a wide support is effectively formed on the hard surface, thereby effectively ensuring that the present invention can be used for high-stability support on hard concrete surfaces.

[0019] The goal is to achieve the following: without excessively increasing the support area of ​​the support column, the support method can be effectively adjusted according to the characteristics of concrete and soil surfaces, so as to achieve high stability of support under different ground conditions, thereby improving construction safety and adaptability.

[0020] 2) The limiting base of the present invention is also provided with a recessed stepped surface, which can provide clearance and embedding for the support seat on the insert, so that the clamping block provided on the tightening sleeve can be pressed onto the support seat simultaneously when the tightening sleeve is lowered into place. This prevents the insert from being lifted due to other factors during the anchoring process, thereby effectively helping to ensure the anchoring stability of the insert during the use of the present invention.

[0021] 3) The clamping block of the present invention is provided with a limiting threaded hole, and the swing limiting sleeve and the insert are respectively provided with corresponding limiting insertion holes. When the clamping sleeve moves downward to form an abutment and fixation on the upper side of the swing limiting sleeve, the clamping block is located above the limiting sleeve, and a limiting bolt with the end of the rod inserted into the limiting insertion hole of the swing limiting sleeve and the insert is fixedly screwed into the limiting threaded hole. This provides a more stable limit for the insert used to expand the support width, thus ensuring the practical effect of the present invention.

[0022] 4) The treadle assembly of the present invention includes a transfer tread located in the middle of the support column and a set of construction treads disposed on the upper part of the support column. A lower climbing ladder located on the outside of the support column is fixedly connected between the support columns below the transfer tread, while an upper climbing ladder located on the inside of the support column and extending to the set of construction treads is fixedly connected between the support columns above the transfer tread. The external lower climbing ladder facilitates the initial climbing work of construction personnel, and the internal upper climbing ladder ensures that the center of gravity of construction personnel shifts inward when further climbing work, thus balancing the convenience and safety of construction personnel when climbing.

[0023] 5) In the set of construction pedals of the present invention, the front side of one construction pedal extends to the outside of the support column, and the rear side of the other construction pedal extends to the outside of the support column. Due to the significant improvement in the support stability of the present invention, the construction pedals of the present invention can be moved outward within a reasonable range, thereby effectively expanding the construction operation space. Furthermore, by moving one of the construction pedals outward in the front and one in the back, the counterweight stability of the present invention can be improved to a certain extent, thereby helping to improve the practical effect of the present invention.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] refer to Figure 1-7 A high-safety scaffolding for steel structure construction, comprising: The scaffold body 1 includes a plurality of support columns 101 and a horizontal connecting rod 102 for connecting the plurality of support columns 101 into a whole. The support columns 101 are provided with construction tread assembly 103. The support assembly 2 includes a limiting base 201 fixed to the bottom end of the support column 101. The inner side of the top of the limiting base 201 is provided with a corresponding inner groove 202 in a ring shape. The top of the limiting base 201 is also provided with a recessed step surface 203 that matches the inner groove 202. The outer side of the limiting base 201 is provided with a plurality of horizontal limiting holes 204 whose inner ends are connected to the inner groove 202 at equal angles. The bottom side of the limiting base 201 is provided with a plurality of vertical limiting holes 205 whose top ends are connected to the inner groove 202 at equal angles. The limiting component 3 includes several swing-limiting sleeves 301 that can be swingably installed in the inner groove 202 of the limiting base 201, and a tightening sleeve 302 that can be lifted and lowered on the support column 101 on the upper side of the limiting base 201. When the swing-limiting sleeve 301 swings upward to abut against the outer wall of the inner groove 202, a skewer insert 303 with its bottom end inserted below the ground is respectively installed between the swing-limiting sleeve 301 and the vertical limiting hole 205. The upper part of the skewer insert 303 is provided with a support seat 304 that is fastened to the concave step surface 203. The tightening sleeve 302... The device descends to form abutment and fixation on the inner side of the swing limiting sleeve 301; when the swing limiting sleeve 301 swings downward to abut the bottom side of the inner groove 202, the side of the insert 303 without the support seat 304 is inserted into the swing limiting sleeve 301 and the horizontal limiting hole 204, and the side of the insert 303 with the support seat 304 is located on the outer side of the limiting base 201. The support seat 304 and the limiting base 201 cooperate to support the device on the ground, and the tightening sleeve 302 descends to form abutment and fixation on the upper side of the swing limiting sleeve 301.

[0034] The support component 2 of the present invention includes a limiting base 201 fixed to the bottom end of the support column 101. The limiting base 201 is provided with an inner groove 202, a horizontal limiting hole 204 and a vertical limiting hole 205 to facilitate the addition of a limiting component 3. The limiting component 3 includes a swing limiting sleeve 301 rotatably installed in the inner groove 202 and a tightening sleeve 302 that is liftably installed on the support column 101.

[0035] When the construction surface is soil, the swing limiting sleeve 301 can be swung upward to abut against the outer wall of the inner groove 202, and the bottom end of the insert 303, which is inserted below the ground, is installed between the swing limiting sleeve 301 and the vertical limiting hole 205. Then, the tightening sleeve 302 is driven downward to abut against the inner side of the swing limiting sleeve 301 to form a stable limit on the swing limiting sleeve 301, thereby forming a stable connection between the insert 303 and the limiting base 201. Under the overall support of the limiting base 201 and the anchoring effect of the insert 303, the invention can be effectively used for high-stability support on soil surfaces.

[0036] When the construction surface is a hard concrete surface, the swing limiting sleeve 301 can be swung downwards to abut against the bottom side of the inner groove 202. Then, one side of the insert 303 is inserted into the swing limiting sleeve 301 and the horizontal limiting hole 204, so that the side of the insert 303 with the support base 304 is located on the outside of the limiting base 201. Then, the tightening sleeve 302 is driven down to abut against the upper side of the swing limiting sleeve 301 to form a stable limit on the tightening sleeve 302, thereby forming a stable connection between the insert 303 and the limiting base 201. With the cooperation of the support base 304 and the limiting base 201, a wide support is effectively formed on the hard surface, thereby effectively ensuring that the present invention can be used for high-stability support on hard concrete surfaces.

[0037] The goal is to achieve the following: without excessively increasing the support area of ​​the support column 101, the support method can be effectively adjusted according to the characteristics of concrete and soil surfaces, thereby achieving high stability of support under different ground conditions, and thus improving construction safety and adaptability.

[0038] A corresponding clamping block 305 is fixedly connected to the tightening sleeve 302. When the tightening sleeve 302 descends and forms an abutment against the inner side of the swing limiting sleeve 301, the clamping block 305 presses against the support base 304. The limiting base 201 of the present invention is also provided with a recessed stepped surface 203, which can make room for the support base 304 on the insert 303, so that the clamping block 305 provided on the tightening sleeve 302 can be pressed against the support base 304 simultaneously when the tightening sleeve 302 descends to its position. This prevents the insert 303 from being lifted due to other factors during the anchoring process, thereby effectively helping to ensure the anchoring stability of the insert 303 during the use of the present invention.

[0039] The clamping block 305 is provided with a corresponding limiting threaded hole, and the swing limiting sleeve 301 and the insert 303 are respectively provided with limiting insertion holes adapted to the limiting threads. When the tightening sleeve 302 moves downward to form an abutment and fixation on the upper side of the swing limiting sleeve 301, the clamping block 305 is located above the swing limiting sleeve 301, and a limiting bolt 306 with its rod end inserted into the limiting insertion hole of the swing limiting sleeve 301 and the insert 303 is fixedly screwed into the limiting threaded hole. With the intervention of the limiting bolt 306, a more stable limit is formed on the insert 303 used to expand the support width, so as to ensure the practical effect of the present invention.

[0040] The support base 304 is arranged in an L-shaped plate. When the support base 304 and the limiting base 201 are supported on the ground, the bottom surface of the support base 304 is fixedly abutting against the ground. This increases the contact area between the support base 304 and the ground, thereby helping to improve the overall support stability of the invention.

[0041] The pedal assembly 103 includes a transfer pedal 1031 located in the middle of the support column 101 and a set of construction pedals 1032 disposed on the upper part of the support column 101. A lower climbing ladder 4 located on the outside of the support column 101 is fixedly connected between the support columns 101 below the transfer pedal 1031. An upper climbing ladder 5 located on the inside of the support column 101 and extending to the set of construction pedals 1032 is fixedly connected between the support columns 101 above the transfer pedal 1031. The external lower climbing ladder 4 facilitates the initial climbing work of construction personnel, while the internal upper climbing ladder 5 ensures that the center of gravity of construction personnel shifts inward when further climbing work, thus balancing the convenience and safety of construction personnel when climbing.

[0042] In one set of construction treads 1032, the front side of one construction tread extends to the outside of the support column 101, and the rear side of the other construction tread extends to the outside of the support column 101. Due to the significant improvement in support stability of the present invention, the construction treads 1032 can be moved outward within a reasonable range, thereby effectively expanding the construction operation space. Furthermore, the outward movement of one of the construction treads 1032 in the set, one in front and one in back, can to a certain extent help improve the counterweight stability of the present invention, thus enhancing its practical effect.

[0043] The outer sides of the lower climbing ladder 4 and the upper climbing ladder 5 are respectively fixed with corresponding annular protective fences 6. The outer perimeter of a set of construction treads 1032 and transfer treads 1031 is respectively fixed with corresponding guardrails 7. The annular protective fences 6 and guardrails 7 ensure the safety of construction personnel when climbing and working at heights.

[0044] The scaffold body 1 is evenly provided with multiple reinforcing rods 8 for structural reinforcement of the support columns 101, horizontal connecting rods 102 and footboard assembly 103. The tightening sleeve 302 is threadedly and vertically connected to the support column 101 on the upper side of the limiting base 201.

[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
