Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to an attached lifting operation safety protection platform for building construction. Background Art

[0002] In the prior art, the protective net for construction is usually fixed on the wall of the building through a support frame arranged on the wall. As the construction progresses of the main building, the protective net is lifted up layer by layer to the floor under construction.

[0003] When lifting the protective net layer by layer, multiple electric hoists are usually used to pull the protective net upward as a whole until it reaches a predetermined height. Since the electric hoists are operated manually, it is impossible to keep the climbing speed of each electric hoist consistent during lifting, which will make the overall climbing speed of the protective net slow and unstable. Generally, it takes one or several days to complete the climbing, and the construction time is long. In addition, this climbing method can only climb upwards but cannot descend downwards. After the construction is completed, the protective net that has climbed to the top floor of the building needs to be manually dismantled, which makes the construction difficult and the construction cost increases accordingly.

[0049] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0050] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0051] Reference Figure 1 to Figure 15 As shown, the embodiment of the present invention discloses an attached lifting operation safety protection platform for construction, which mainly includes:

[0052] A lifting column 100 is arranged on the outside of a building wall 500 in a vertical direction;

[0053] The attachment mechanism comprises three rows of fixed attachment supports 200 and two movable attachment supports 200 which are arranged at equal intervals along the height direction of the lifting column 100; each row of fixed attachment supports 200 comprises two attachment supports 200 which are fixed and symmetrically arranged on both sides of the lifting column 100, and the two movable attachment supports 200 can move in the vertical direction, and each movable attachment support 200 can be located in the middle of two attachment supports 200 in one row of fixed attachment supports 200 when moving in the vertical direction; the spacing between each movable attachment support 200 is the same as the spacing between each row of fixed attachment supports 200;

[0054] A plurality of embedded parts 300 are arranged in the building wall 500 at equal intervals and are adapted to the attachment mechanism so that the attachment support 200 in the attachment mechanism can be inserted into and locked accordingly;

[0055] The main frame 400 is vertically arranged on the lifting column 100 and is located at a side away from the building wall 500 . A scaffolding board is arranged on the main frame 400 .

[0056] In this embodiment, in order to facilitate the climbing or descending of the protection net, each time the protection net climbs or descends, it corresponds to climbing one floor of the main building. Therefore, when the safety protection platform described in the embodiment of the present invention is used, the main building needs to be built to the third floor or above. The attached lifting operation safety protection platform for construction can be attached and fixed on the wall of the building, and can load the entire protection net to climb upward or descend on the outer wall of the building.

[0057] The lifting column is arranged on the outside of the building wall in the vertical direction, and a main frame for setting up a protective net is installed behind it, which is also arranged in the vertical direction. In practical applications, in order to form an integral protective net on the outer wall of the building, it is generally necessary to arrange multiple lifting columns side by side to cover the entire building wall horizontally, and at the same time, the same number of main frames are arranged on each lifting column, and the spacing between each lifting column is usually set to 2~5 meters. Generally, the floor height of the main building is 3 meters, and the height of the entire lifting column is about 6.3 meters.

[0058] Scaffolding boards are laid between each main frame to form a three-layer scaffolding, and a safety mesh is set on the outside of the scaffolding to form a protective net. The main frame has upward and downward extending parts at the top and bottom of the lifting column, so that the construction floor can be covered as comprehensively as possible.

[0059] Correspondingly, an attachment mechanism is provided on the side of the lifting column opposite to the building wall, and the attachment mechanism includes three rows of fixed attachment supports and two movable attachment supports arranged at equal intervals along the height direction of the lifting column. By alternately climbing or descending the three rows of fixed attachment supports and the two movable attachment supports, the purpose of the protective net climbing one floor of the building main body each time it climbs or descends can be achieved.

[0060] Among them, three rows of fixed attachment supports are arranged at equal intervals along the height direction of the lifting column, and each row of fixed attachment supports includes two fixed and symmetrically arranged attachment supports on both sides of the lifting column; two movable attachment supports are arranged on the lifting column at equal intervals along the height direction of the lifting column and can move in the vertical direction, and each movable attachment support can be located in the middle of two attachment supports in one row of fixed attachment supports when moving in the vertical direction. In the specific arrangement, the three rows of fixed attachment supports are respectively arranged at the top, middle and bottom positions of the lifting column.

[0061] In addition, the spacing between the movable attachment supports is the same as the spacing between the fixed attachment supports in each row, so that the movable attachment supports can be on the same horizontal plane as the two fixed attachment supports in one row and symmetrically arranged on both sides of the lifting columns when moving in the vertical direction. In the specific setting, the spacing between the three rows of fixed attachment supports and the spacing between the two movable attachment supports is the same as the floor height of the building, which is generally about 3 meters.

[0062] A plurality of embedded parts respectively adapted to the attachment mechanism are also arranged on the wall of the building, and are arranged at equal intervals in the vertical direction to form a row, so that the attachment supports in the attachment mechanism can be inserted into and locked accordingly. Each embedded part is usually arranged at a position close to the top floor of each floor, and the spacing between them is the same as the spacing between each row of fixed attachment supports or two movable attachment supports. The attachment supports in a row on the lifting column can be inserted into the corresponding embedded parts and locked, so that the protective net on the lifting column is attached to the wall of the building as a whole. In specific implementation, the number of columns of embedded parts is the same as the number of lifting columns, and the number of embedded parts set in each column is the same as the total number of floors of the building.

[0063] Initially, the two movable attachment supports on the lifting column are respectively dropped vertically to the middle and bottom positions of the lifting column, and together with the two rows of fixed attachment supports at the middle and bottom positions of the lifting column, they are extended into the corresponding embedded parts on the building wall and locked, while the row of fixed attachment supports at the top position of the lifting column is extended into the corresponding embedded parts on the building wall and locked, so that the protective net on the lifting column is attached to the building wall as a whole. Figure 1 and Figure 2 As shown, Figure 1 and Figure 2 The diagram shows the initial state of the attached lifting safety protection platform for construction according to the embodiment of the present invention when it is attached to the wall of a building.

[0064] After a new floor of the building is constructed, the protective net needs to be raised up one floor as a whole. At this time, the two movable attachment supports on each lifting column contract to separate them from the connection with the embedded parts, and then they are driven by the lifting column to rise in the vertical direction to the middle and top positions of the lifting column, that is, they rise to the embedded parts corresponding to the previous floor respectively. Then, the two movable attachment supports are opened, and then they are respectively extended into the embedded parts extended into by the two rows of fixed attachment supports at the middle and top positions on the lifting column and locked. Afterwards, the three rows of fixed attachment supports on each lifting column are contracted to separate them from the connection with the embedded parts, and then they are driven by the lifting column to rise in the vertical direction to the embedded parts corresponding to the previous floor respectively. Then, the three rows of fixed attachment supports are opened, extended into the embedded parts corresponding to the previous floor and locked, completing the process of the protective net climbing up one floor as a whole. Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 The diagram shows the state of the attached lifting work safety protection platform for construction according to the embodiment of the present invention after it is attached to the wall of a building and climbed up one floor.

[0065] When the overall construction of the building is completed, the protective net can be lowered layer by layer until it reaches the lowest floor, which is convenient for removal. The specific process of the overall lowering of the protective net is opposite to the above-mentioned climbing process, so it can be implemented with reference to the above-mentioned climbing process and will not be repeated here.

[0066] When the protective net is climbing or descending as a whole, each lifting column needs to maintain synchronous movement, so that the protective net as a whole can be automatically, smoothly and quickly attached and lifted.

[0067] It should be noted that those skilled in the art can also set other rows of fixed attachment supports and a corresponding number of movable attachment supports on the lifting columns according to actual usage requirements, and set the corresponding number of embedded parts at the same time, which can also achieve the purpose of climbing or descending the protective net on the wall of the building. The specific setting method will not be repeated here.

[0068] In summary, under the joint action of the lifting columns, attachment supports and embedded parts, the entire protective net can be attached to the wall of the building; at the same time, the attachment supports and embedded parts can quickly realize connection and disconnection with the wall of the building, and then utilize the lifting and lowering of the lifting columns, and the alternating climbing and descending of the three rows of fixed attachment supports and the two movable attachment supports on the lifting columns to realize the overall climbing and descending of the protective net. The climbing and descending speed is fast and stable, overcoming the defects of constantly dismantling the support frame and then rebuilding it, thereby saving construction time, saving construction costs, and reducing construction difficulty, with high safety and convenient construction operation.

[0069] Based on the above embodiments, in a specific implementation scheme, specifically refer to Figure 5~Figure 10 As shown, the lifting column 100 mainly includes:

[0070] The steel seat 101 is a columnar structure with a C-shaped cross section and has a notch 1011 arranged along the height direction; three rows of fixed attachment supports 200 are arranged at equal intervals along the height direction on the outside of the steel seat 101;

[0071] The screw rod 102 is arranged in the steel seat 101 and close to the side of the slot 1011. A driving motor 103 is arranged on the top of the screw rod 102 to drive the screw rod 102 to rotate. Two movable attachment supports 200 extending from the slot 1011 to the outside of the steel seat 101 are arranged on the screw rod 102 at equal intervals along its height direction.

[0072] A plurality of guide wheels 104 are respectively arranged on both sides of the screw rod 102 in pairs along the height direction of the screw rod 102 , one circumferential surface of the two guide wheels 104 faces each other, and the other circumferential surface contacts the inner wall of the steel seat 101 .

[0073] In this embodiment, the lifting column includes a steel base of a column structure, whose cross section is C-shaped and one side of which has a notch along the height direction. The steel base can be made of square steel with a hollow interior and a wall thickness of 5 mm, and a notch can be opened on one side of the steel base along the height direction.

[0074] A screw rod is arranged in the steel seat, and a driving motor is arranged on the top of the screw rod, so that the screw rod can rotate under the drive of the driving motor. Therefore, two movable attachment supports are further arranged on the screw rod at equal intervals along its height direction, and the two movable attachment supports can extend out of the steel seat from the notch of the steel seat and move up and down in the vertical direction following the rotation of the screw rod.

[0075] Similarly, after further symmetrically arranging three rows of fixed attachment supports at equal intervals on both sides of the outside of the steel base, since the spacing between the two movable attachment supports is the same as the spacing between the three rows of fixed attachment supports, the movable attachment supports can be located on the same horizontal plane as the two fixed attachment supports in one of the rows when moving in the vertical direction.

[0076] When the protective net needs to be lifted up by one floor, the driving motor rotates forward to make the screw rod rotate forward, driving the two movable attachment supports to move upward in the vertical direction, so that the two movable attachment supports rise from the bottom and middle positions of the lifting column to the middle and top positions of the lifting column, that is, rise to the embedded parts corresponding to the previous floor, and the two movable attachment supports are opened and extended into the embedded parts corresponding to the previous floor and locked. Afterwards, the driving motor is reversed to make the screw rod rotate in the opposite direction, driving the two movable attachment supports to move downward in the vertical direction, so that the two movable attachment supports fall from the top and middle positions of the lifting column to the middle and bottom positions of the lifting column.

[0077] Since the two movable attachment supports are always locked by the embedded parts during this process, when the two movable attachment supports move downward in the vertical direction, the steel seat will drive the three rows of fixed attachment supports set thereon to rise in the opposite direction. When rising, the three rows of fixed attachment supports will all shrink to break away from the connection with the embedded parts, and then, driven by the steel seat, they will rise vertically to the embedded parts corresponding to the upper floor respectively, and then the three rows of fixed attachment supports will open and extend into the embedded parts corresponding to the upper floor and be locked, thus completing the process of the overall protective net climbing up one floor.

[0078] A plurality of guide wheels are also arranged in the steel seat, and are arranged in pairs on both sides of the screw rod along the height direction of the screw rod. Since the bottom of the screw rod is not connected to the steel seat, when the screw rod rotates under the drive of the driving motor, two guide wheels are arranged on both sides thereof, and one of the circumferential surfaces of the two guide wheels is opposite, and the other circumferential surface is respectively in contact with the inner wall of the steel seat, so that the screw rod can be positioned in the vertical direction to prevent it from being offset during the rotation process, so as to ensure that the two movable attachment supports arranged on the screw rod can accurately extend into the corresponding embedded parts and be locked.

[0079] In addition, an electrical control cabinet is provided on the scaffolding board laid on the main frame, and the electrical control cabinet is connected to the drive motor signal to control the drive motor. When the protective net is climbing or descending as a whole, the electrical control cabinet uniformly controls the drive motors on each lifting column, so that each lifting column maintains synchronous movement, so that the protective net as a whole can automatically, smoothly and quickly perform an attached lifting operation. Preferably, the electrical control cabinet is a PLC control cabinet.

[0080] Based on the above embodiments, in a specific implementation scheme, specifically refer to Figure 5~Figure 10 and Fig.11As shown, two fixing components 105 are arranged on the screw rod 102 at equal intervals along its height direction, and the fixing component 105 includes a screw nut 1051 and a guide seat 1052, the screw nut 1051 is sleeved on the screw rod 102, and the guide seat 1052 is sleeved on the screw nut 1051; the guide seat 1052 is sleeved on the screw nut 1051. The two sides of one end of the guide seat 1052 are respectively provided with mounting rods 1052-1, and the guide wheel 104 is arranged on the mounting rod 1052-1, and the other end of the guide rod 1052-1 extends outward from the notch 1011 to the outside of the steel seat 101 to connect the movably arranged attachment support 200;

[0081] The steel seat 101 is provided with three rows of fixed seats 106 at equal intervals along its height direction to connect the fixed attachment supports 200 respectively.

[0082] In this embodiment, two fixing components are arranged on the screw rod at equal intervals along its height direction, and the fixing components further include a screw rod nut and a guide seat. The screw rod nut is generally a copper nut, which is directly sleeved on the screw rod, and the guide seat is further sleeved on the screw rod nut.

[0083] Preferably, in a specific embodiment, specific reference is made to Fig. 9 As shown, the guide seat 1052 is an irregular part, which includes a screw connection part 1052-1, an extension part 1052-2 and a support connection part 1052-3, and the support connection part 1052-3 is connected to the screw connection part 1052-1 through the extension part 1052-2. The screw connection part 1052-1 is a cylindrical structure with a through hole opened along its height direction, which is sleeved on the screw nut 1051; the extension part 1052-2 and the support connection part 1052-3 are both rectangular parallelepiped structures, and the extension part 1052-2 and the support connection part 1052-3 are arranged perpendicular to each other so that the side with the largest area of ​​the support connection part 1052-3 is opposite to the screw connection part 1052-1, and the support connection part 1052-3 extends outward from the notch 1011 of the steel seat 101 to the outside of the steel seat 101 to connect the movable attachment support 200. The guide seat 1052 is sleeved on one end of the screw nut 1051, namely the screw connecting portion 1052-1, and mounting rods 1052-5 are respectively provided on both sides thereof, and the two guide wheels 104 are correspondingly mounted on the two mounting rods 1052-5.

[0084] A plurality of rows of column mounting holes 1052 - 4 are arranged in parallel along the height direction on the support connecting portion 1052 - 3 in the guide seat 105 , and the attachment support 200 is connected through the column mounting holes 1052 - 4 .

[0085] In addition, three rows of fixed seats are evenly spaced along the height direction of the steel base. One end of the fixed seat is fixed to one side of the steel base, and the other end extends to the side of the steel base with a groove to connect to the fixed attachment supports respectively. In this way, when the movable attachment support moves in the vertical direction to the middle position between the two fixed attachment supports, it can be side by side with the two fixed attachment supports and be located on the same horizontal plane.

[0086] Based on the above embodiments, in a specific implementation scheme, specifically refer to Figure 5~Figure 9 As shown, a coupling 107 and a reducer 108 are also provided on the top of the screw rod 102. The coupling 107 is arranged above the screw rod 102 and connected to the top of the screw rod 102. The reducer 108 is arranged above the coupling 107 and connected to the coupling 107. The drive motor 103 is arranged above the reducer 108 and connected to the reducer 108.

[0087] In this embodiment, a coupling and a reducer are further arranged on the top of the screw rod. The reducer is connected to the drive motor, which can slow down the rotation speed output by the drive motor to the screw rod, so that the screw rod can rotate more smoothly, thereby making the overall rise or fall of the protective net more stable.

[0088] A coupling is also connected between the reducer and the screw rod, which rotates together in the process of transmitting the motion and power output by the reducer to the screw rod, and is used to connect the output shaft of the reducer and the screw rod. At the same time, it can also be used to prevent the connected mechanism from bearing excessive loads, playing the role of overload protection.

[0089] In addition, the reducer is also connected to the electrical control cabinet signal to accept the control of the electrical control cabinet. When the protective net is climbing or descending as a whole, the electrical control cabinet also uniformly controls the reducers on each lifting column, so that each lifting column maintains synchronous movement, so that the protective net as a whole can automatically, smoothly and quickly attach and lift.

[0090] Based on the above embodiments, in a specific implementation scheme, specifically refer to Figure 5~Figure 9 As shown, a plurality of connecting fasteners 109 are provided along the height direction of the outer side of the steel seat 101 opposite to the notch 1011 to connect to the main frame 400 .

[0091] In this embodiment, a plurality of connecting fasteners are arranged at the back of the steel seat along its height direction, and the connecting fasteners are used to install the main frame.

[0092] The connecting fastener includes two parts, one of which is fixedly arranged on the steel base, and the other part is connected to the steel base by bolts. After the two parts are connected, a hollow structure that can accommodate the frame of the main frame is formed in the middle. This arrangement facilitates the connection and removal of the main frame.

[0093] Based on the above embodiments, in a specific implementation scheme, specifically refer to Figure 5~Figure 9 As shown, a plurality of rows of anti-falling grooves 1012 are arranged in parallel on the steel seat 101 along its height direction, and each row of anti-falling grooves 1012 includes two anti-falling grooves 1012 symmetrically arranged on both sides of the notch 101 .

[0094] In this embodiment, a plurality of rows of anti-falling grooves are further arranged on one side of the steel seat having the notch, wherein each row of anti-falling grooves includes two anti-falling grooves symmetrically arranged on both sides of the notch.

[0095] The anti-fall device adapted to the anti-fall groove can be pre-fixed on the wall of the building, or can be set on two movably arranged attachment supports and move together in the vertical direction. One end of the anti-fall device is fixed on the wall of the building or on the movably arranged attachment support, and the other end can be abutted on the anti-fall groove, which can effectively prevent the lifting column from accidentally falling during the ascent or descent process. The anti-fall device adopts the anti-fall structure in the prior art, and its structure is not repeated here.

[0096] Based on the above embodiments, in a specific implementation scheme, specifically refer to Figure 5~Figure 10 and Fig.12 The attachment support 200 includes a connecting flange 201, a cantilever beam 202 and a connecting seat 203. One end of the cantilever beam 202 is connected to the upper end of the connecting flange 201 and can move in the vertical direction. One end of the connecting seat 203 is connected to the lower end of the connecting flange 201 and can move in the vertical direction. The other end of the cantilever beam 202 is provided with a first through hole 2021, and the other end of the connecting seat 203 is provided with a second through hole 2031. The first rotating shaft 204 passes through the first through hole 2021 and the second through hole 2031 to movably connect the other end of the cantilever beam 202 and the other end of the connecting seat 203. The other end of the cantilever beam 202 has a protrusion 2022 extending downward.

[0097] In this embodiment, the fixed attachment support and the movable attachment support can adopt the same structure, and the attachment support includes a connecting flange, a cantilever beam and a connecting seat. The connecting flange is vertically arranged for connecting with the lifting column. One end of the cantilever beam and the connecting seat are respectively arranged at the upper end and the lower end of the connecting flange, and are movable in the same vertical direction. The other end of the cantilever beam is provided with a first through hole, and the other end of the connecting seat is also provided with a second through hole. The first rotating shaft passes through the first through hole and the second through hole to movably connect the other end of the cantilever beam and the other end of the connecting seat.

[0098] When the attachment support extends into the corresponding embedded part and is locked, the connection seat is in a horizontal state perpendicular to the connection flange, and the cantilever beam is in an inclined downward state. At this time, the protrusion extending downward on the other end of the cantilever beam extends into the embedded part, so that the attachment support is locked in the embedded part. The cross section of the protrusion is generally set to be rectangular.

[0099] When the lifting column moves upward, it drives each attachment support to move upward as a whole. At this time, the cantilever beam contacts the embedded part and causes the embedded part to generate a force to press the cantilever beam downward, so that the other end of the cantilever beam moves downward around its end set on the connecting flange. At this time, the first rotating shaft slides along the second through hole from the other end of the connecting seat to the end connected to the connecting flange, so that the other end of the connecting seat also moves downward around its end set on the connecting flange, thereby completing the contraction of the attachment support.

[0100] When each attachment support reaches the corresponding embedded part, the operator needs to manually open each attachment support, that is, push the connecting seat and the cantilever beam upward to make the connecting seat perpendicular to the connecting flange, so that the attachment support can extend into the corresponding embedded part and be locked.

[0101] The various attachment supports cooperate with the lifting columns, so that the protective net can be attached to the wall of the building as a whole, can be quickly connected to and disconnected from the wall of the building, and can well cooperate with the rise and fall of the lifting columns, ultimately realizing the overall automatic, smooth and fast attachment lifting operation of the protective net, making the operation process more convenient.

[0102] Based on the above embodiments, in a specific implementation scheme, two elastic components are respectively arranged between the two opposite surfaces of the connecting flange 201 and the cantilever beam 202; or, a motor is arranged between the two opposite surfaces of the connecting flange 201 and the cantilever beam 202.

[0103] In this embodiment, since the attachment support of the above structure needs manual operation to be opened after shrinkage so that it can be extended into the embedded part and locked, the operation process is slightly inconvenient, so the following two preferred implementation schemes are proposed to realize the automatic opening of the attachment support.

[0104] In a first preferred embodiment, two elastic components, such as springs, are respectively arranged between the connecting flange of the attachment support and the two opposite surfaces of the cantilever beam. When the attachment support is in a compressed state and follows the lifting column to reach the corresponding embedded part, the embedded part does not contact the cantilever beam at this time, and therefore does not generate a downward force on the cantilever beam. Under the elastic force of the elastic component arranged between the connecting flange and the cantilever beam, the other end of the cantilever beam moves upward around its end arranged on the connecting flange, and the first rotating shaft slides along the second through hole from one end of the connecting seat connected to the connecting flange to the other end, so that the other end of the connecting seat also moves upward around its end arranged on the connecting flange, so that the connecting seat is perpendicular to the connecting flange, and the attachment support automatically opens, so that the attachment support can extend into the corresponding embedded part and be locked.

[0105] In a second preferred embodiment, a motor, which may be a micro motor, is arranged between the two opposite surfaces of the connection flange of the attachment support and the cantilever beam. When the attachment support is in a compressed state and follows the lifting column to reach the corresponding embedded part, the embedded part does not contact the cantilever beam at this time, and therefore does not generate a downward force on the cantilever beam. Under the force output by the motor arranged between the connection flange and the cantilever beam, the other end of the cantilever beam moves upward around its end arranged on the connection flange, and the first rotating shaft slides along the second through hole from one end of the connection seat connected to the connection flange to the other end, so that the other end of the connection seat also moves upward around its end arranged on the connection flange, so that the connection seat is perpendicular to the connection flange, and the attachment support automatically opens, so that the attachment support can extend into the corresponding embedded part and be locked.

[0106] It should be noted that, without affecting the understanding and implementation of the technical solution by those skilled in the art, the structures of the two preferred solutions are not specifically shown in the accompanying drawings. Those skilled in the art can implement the technical solution and achieve the corresponding technical effects based on the descriptions in other accompanying drawings and the specification.

[0107] Preferably, in a specific embodiment, specific reference is made to Fig.12 As shown, a first mounting portion 2011 is provided at the upper end of the connecting flange 201, and a second mounting portion 2012 is provided at the lower end of the connecting flange 201; one end of the cantilever beam 202 is connected to the first mounting portion 2011 through the second rotating shaft 204, and one end of the connecting seat 203 is connected to the second mounting portion 2012 through the third rotating shaft 206.

[0108] Specifically, the upper and lower ends of the connecting flange are respectively provided with an extended first mounting portion and a second mounting portion, and the cantilever beam and one end of the connecting seat are respectively installed through two rotating shafts, so that the cantilever beam and one end of the connecting seat are easier to move in the vertical direction, and will not touch the connecting flange during movement, and the resistance encountered is small, which facilitates the contraction of the attached support.

[0109] Preferably, in a specific embodiment, specific reference is made to Fig.12 As shown, at least one row of support mounting holes 2013 are arranged in parallel along the vertical direction on the connecting flange 201, and each row of support mounting holes 2013 includes two support mounting holes 2013 located on the same horizontal line.

[0110] Specifically, the connecting flange is provided with multiple rows of support mounting holes in parallel along the vertical direction, and the entire attachment support can be installed on the lifting column through the support mounting holes. Similarly, the support connecting portion provided on the lifting column for installing the attachment support is also provided with multiple rows of column mounting holes in parallel, so that when installing the attachment support, the installation position of the attachment support can be appropriately adjusted according to the actual position of the embedded part, and one of the rows of support mounting holes on the connecting flange of the attachment support can be selected to be aligned with one of the rows of column mounting holes on the support connecting portion on the lifting column, and then the attachment support is installed on the lifting column through bolt connection, while ensuring that the attachment support can be inserted into the corresponding embedded part and locked.

[0111] Preferably, in a specific embodiment, specific reference is made to Fig.12 As shown, the cross-section of the protrusion 2022 is rectangular.

[0112] In this embodiment, when the attachment support is extended into and locked in the embedded part, the protrusion is just located in the positioning groove in the embedded part. The cross-section of the protrusion is set to a rectangle, so that the contact surface between the protrusion and the positioning groove can be a vertical surface, so that the protrusion is not easy to slip out of the positioning groove, and the attachment support is easier to be locked by the embedded part, thereby improving safety.

[0113] Based on the above embodiments, in a specific implementation scheme, specifically refer to Figure 13~Figure 15 As shown, the embedded part 300 includes a connecting part 301 and an external part 302 that are connected to each other. The connecting part 301 is arranged inside the building wall 500, and the external part 302 is arranged outside the building wall 500; the connecting part 301 and the external part 302 are both rectangular hollow structures, and the interior of the connecting part 301 is connected with the interior of the external part 302; an opening for the attachment support 200 to extend into is provided on the side of the external part 302 away from the connecting part 301, and a positioning groove 3021 for accommodating and fixing the protrusion 2022 is provided on the bottom surface thereof.

[0114] In this embodiment, the embedded part is a hollow structure with one end open, which is composed of a connecting part and an external part connected to each other. The connecting part and the external part are both rectangular hollow structures, and the interior of the connecting part is connected to the interior of the external part. An opening for the attachment support to extend into is provided on the side of the external part away from the connecting part, and a positioning groove for accommodating the protrusion is provided on the bottom surface.

[0115] The embedded parts are pre-set on the wall of the building during the construction of the main structure of the building, and their openings are outward for the attachment support to extend in. Specifically, the connecting parts are set inside the wall of the building, and the external hanging parts are set outside the wall of the building, and the openings on the external hanging parts face the attachment support for the attachment support to extend in.

[0116] In a specific implementation, the four surfaces connecting the external component and the connecting component all extend toward one end of the connecting component and extend into the interior of the connecting component, so that the connection between the external component and the connecting component can be more firmly established.

[0117] The cross section of the positioning groove is also set to a shape that matches the protrusion on the attachment support, so that when the attachment support extends into the embedded part, the positioning groove can completely accommodate the protrusion, so that the embedded part can lock the attachment support, further allowing the lifting column to reach the preset load-bearing capacity.

[0118] In this embodiment, the cross-section of the positioning groove is set to a rectangle, so that the contact surface between the protrusion and the positioning groove can be a vertical surface, so that the protrusion is not easy to slip out of the positioning groove, and the attachment support is easier to be locked by the embedded part, thereby improving safety.

[0119] Based on the above embodiments, in a specific implementation scheme, specifically refer to Figure 13~Figure 15 As shown, a fixing hole 3011 is provided on the side of the connecting member 301 away from the external member 302, and a through-wall bolt 3012 passes through the fixing hole 3011 and the building wall 500 in sequence, so that the embedded member 300 is fastened to the building wall 500, and the tail of the through-wall bolt 3012 passes through the building wall 500 and is fixed by a nut 3013 and a first gasket 3014; a second gasket 3022 is provided on the bottom surface of the positioning groove 3021, and a positioning hole is provided on the second gasket; the fixing bolt 3023 passes through the positioning hole and the protrusion 2022 in sequence, so that the protrusion 2022 is fixed in the positioning groove 3021.

[0120] In this embodiment, a fixing hole is provided on the side of the connecting member away from the external hanging member, so that the through-wall bolt can pass through the fixing hole and the building wall in sequence, thereby further fastening the entire embedded member to the building wall.

[0121] When the attachment support is inserted into the embedded part and locked, the main frame installed behind the lifting column connected to the attachment support will be attached to the wall of the building. Since the weight of the lifting column and the main frame is relatively large, the attachment support and the embedded part will inevitably receive a downward pulling force. After the embedded part is tightened by the through-wall bolt, the fixing force of the building wall on the embedded part will be increased, making the embedded part less likely to loosen, improving the load-bearing capacity of the embedded part, and improving safety performance.

[0122] When the embedded part is fastened to the wall of the building by the through-wall bolt, the tail of the through-wall bolt passes through the fixing hole on the connecting part and the building wall in turn, and the head thereof is clamped at the connection between the connecting part and the external part. After the tail of the through-wall bolt passes through the building wall, the nut is screwed on the through-wall bolt. At the same time, a first gasket is also arranged between the nut and the building wall to make the connection more secure. The first gasket is made of a rigid material, which is slightly larger than the size of the fixing hole, and can cover the fixing hole to fix the through-wall bolt.

[0123] In addition, in order to fasten the protrusion on the attachment support in the positioning groove, a second gasket is further provided on the bottom surface of each positioning groove, and a positioning hole is also provided on the second gasket. When the protrusion is located in the positioning groove, the fixing bolt is passed through the positioning hole and the protrusion in sequence, so that the protrusion is fixed in the positioning groove. The second gasket is made of rigid material, which is slightly larger than the size of the positioning groove and can cover the positioning groove to prevent the attachment support from retracting, further improving the connection firmness between the attachment support and the embedded part, thereby improving the overall load-bearing capacity and safety.

[0124] To summarize, an embodiment of the present invention provides an attached lifting work safety protection platform for construction, which is achieved by arranging a lifting column with multiple rows of attachment supports in the vertical direction, and arranging embedded parts compatible with the attachment supports on the building wall opposite to the lifting column, so that when the attachment supports are extended into the corresponding embedded parts and locked, the protection net arranged behind the lifting column can be fixed on the building wall; at the same time, the attachment supports and the embedded parts can be quickly connected and disconnected from the building wall, and then the lifting and lowering of the lifting column, as well as the alternating climbing and descending of the three rows of fixed attachment supports and the two movable attachment supports on the lifting column are coordinated to achieve the overall climbing and descending of the protection net.

[0125] The entire platform has a simple structure, and it climbs and descends quickly and smoothly, overcoming defects such as the need to constantly dismantle and rebuild the support frame, thereby saving construction time, saving construction costs, and reducing construction difficulty. It is highly safe and easy to operate.
