Description

Technical Field

[0001] The invention relates to the technical field of expansion joint protection in construction engineering, and in particular to a tool-type horizontal safety protection device for expansion joints of high-rise buildings. Background Art

[0002] In the design of high-rise buildings, expansion joints are often set along the length of the building to prevent cracks caused by climate temperature changes, so that the building can expand and contract horizontally along the long side as the temperature changes. During the construction process, in order to facilitate the passage of construction workers and the transportation of materials, the passage and transportation channels often need to pass through the expansion joints. The existing conventional protection measures usually make steel mesh frames that are suitable for the size of the expansion joints and cover them with frame plates. The safety protection of the expansion joints is poor, and materials are prone to fall into the expansion joints. Especially when the expansion joints are wide, whether the construction workers are working on the working layer or walking under the expansion joints, the safety risks are very high. The existing disclosed technologies "A concrete expansion joint protection device" (application number: 201720864417.1) and "A expansion joint protection device for construction projects" (application number: 202010461345.2) both set the protection devices at the expansion joints between floor slabs, which are suitable for use on completed floor slabs. They cannot adapt to the situation where a passage and transfer channel needs to be established under the expansion joints of the main construction operation layer, that is, they cannot meet the needs of protecting both the workers on the construction layer and the people passing below at the same time. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide a tool-type horizontal safety protection device for expansion joints of high-rise buildings, so as to adapt to the situation where a passage and transfer passage needs to be established under the expansion joint of the construction layer. It can not only protect the passage of people on the lower floor, but also ensure the safety of workers on the construction layer and avoid safety hazards during the construction process. It is suitable for the expansion joint position between two units of a high-rise building and a door opening is set in the middle of the outer wall at the expansion joint during construction.

[0004] The present invention solves the above problems by the following technical means:

[0005] A tool-type horizontal safety protection device for expansion joints of high-rise buildings, comprising a protection panel, a support frame, a clamp and a support. The protection panel is arranged at the expansion joint between construction layers, and below the protection panel is a passage for personnel passage and material transfer, and both sides of the expansion joint are passage door openings, which are openings designed below the connecting beam of the external wall at the expansion joint; the top of the support frame is connected to the protection panel to provide vertical support for the protection panel, and the support frame includes two frames arranged symmetrically on the left and right; the clamp and the support are respectively arranged in the middle and bottom of the frame, and the two ends of the clamp and the support are respectively clamped and arranged at the upper and lower corners of the passage door openings on both sides, which provide a basic fulcrum for the entire device and prevent the device from overturning during use.

[0006] The length and width of the protective panel match the size of the expansion joint, which can not only meet the needs of safety protection, but also facilitate lifting and transportation. The protective panel includes a panel frame and a cover plate. The panel frame includes two longitudinal beams and multiple cross beams spanning between the two longitudinal beams. The two longitudinal beams are arranged side by side at intervals, and the spacing is adapted to the width of the protective panel. The two ends of the cross beam are respectively fixedly connected to the two longitudinal beams and arranged at intervals. The spacing between the two cross beams at the end of the protective panel is the same as the length of the panel. In order to enhance the structural stability of the panel frame, adjacent cross beams are connected with oblique web beams, and adjacent cross beams and oblique web beams form a "Z"-shaped structure or a reverse "Z"-shaped structure. The "Z"-shaped structure and the reverse "Z"-shaped structure are arranged alternately in sequence; the cover plate is set on the panel frame. In order to facilitate lifting and transportation, two lifting rings are symmetrically set on the surface of the cover plate.

[0007] The frame includes columns and diagonal braces. The columns serve as the main vertical force-transmitting components of the frame, and the top and bottom of the columns are respectively connected to the protective panel and the support. One end of the diagonal brace is connected to the end of the corresponding side of the protective panel, and the other end is connected to the middle of the column. The columns, diagonal braces and protective panels together form a triangular support system. In order to enhance the structural stability, vertical and diagonal web members are arranged between the protective panel and the diagonal braces. One end of the vertical web member is connected to the midpoint of the diagonal brace, and the other end is connected to the protective panel. One end of the diagonal web member is connected to the midpoint of the diagonal brace, and the other end is connected to the intersection of the protective panel and the column.

[0008] The clamp is installed on the column, and the installation height should be sufficient to clamp the frame at the upper corner of the passage door. The clamp includes a sleeve and a stopper rod that are slidably connected. The sleeve is made of square steel pipe, the length is the same as the width of the protection panel, and the cross-sectional size is determined comprehensively according to the column and support model; the stopper rod is made of square steel pipe, the cross-sectional size is consistent with the sleeve size, and the length should be sufficient to exceed the distance between the passage door openings on both sides of the expansion joint after installation and clamp the frame. The clamp can be disassembled and installed according to the needs of hoisting and erection, which is convenient for hoisting and transportation while ensuring the stability of the safety protection device and preventing overturning.

[0009] Furthermore, when in use, the clamp can be slid to adjust the height as needed. After the height positioning is completed, the stopper, sleeve and column are locked by bolts through the reserved bolt holes. A preferred design scheme is: the two inner side walls opposite to each other of the column are provided with vertically extending sliding tracks, and the clamp is slidably matched with the sliding track through a sliding assembly; the part of the column located above the bottom end of the diagonal support is vertically spaced with a plurality of bolt holes, and the sliding assembly is slidably locked by bolts assembled with bolt holes of corresponding heights. More specifically, the clamp includes a sleeve and a stopper that are slidably sleeved, and the sliding assembly includes a connecting plate fixedly connected to the sleeve, a pulley frame fixedly connected to the connecting plate, and a pulley rotatably assembled on the pulley frame, and the pulley is slidably matched with the sliding track, and the bolt passes through the connecting plate and is assembled and connected with the bolt hole of corresponding height to achieve sliding locking of the sliding assembly.

[0010] The support is set at the bottom of the column, providing a basic fulcrum for the entire device, including a sliding sleeve connection groove and a support crossbar, and the connection groove and the support crossbar are locked by bolts. The connection groove is made of channel steel, connected to the column, and the length is the same as the width of the protective panel. The outer spacing of the two connection grooves is the same as the width of the passage door opening; the support crossbar is made of square steel, the model is adapted to the connection groove, and the length should be sufficient to exceed the distance between the passage door openings on both sides of the expansion joint after installation and support the frame firmly. The two ends of the support crossbar are respectively connected to the completed floor surface support on both sides of the expansion joint.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present invention will become clearer and more specific. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0025] like Figure 1-9 As shown, the tool-type horizontal safety protection device for expansion joints of high-rise buildings of this embodiment includes a protection panel 2, a support frame, a clamp and a support. The protection panel 2 is arranged at the expansion joint between the construction layers 12. Below the protection panel is a passage for personnel passage and material transfer. Both sides of the expansion joint are passage door openings, which are openings designed below the connecting beam of the external wall at the expansion joint. The top of the support frame is connected to the protection panel 2 to provide vertical support for the protection panel 2. The support frame includes two frames arranged symmetrically on the left and right. The clamp and the support are respectively arranged in the middle and bottom of the frame, and the two ends of the clamp and the support are respectively clamped and arranged at the upper and lower corners of the passage door openings on both sides, which provide a basic fulcrum for the entire device and prevent the device from overturning during use.

[0026] The length and width of the protective panel 2 match the size of the expansion joint, which can meet the needs of safety protection and facilitate lifting and transportation. The protective panel 2 includes a panel frame and a cover plate. The panel frame includes two longitudinal beams 14 and multiple cross beams 16 spanning between the two longitudinal beams 14. The two longitudinal beams 14 are arranged side by side at intervals, and the spacing is adapted to the width of the protective panel 2. The two ends of the cross beam 16 are respectively fixedly connected to the two longitudinal beams 14 and arranged at intervals. The spacing between the two cross beams 16 at the end of the protective panel 2 is the same as the length of the panel. In order to enhance the structural stability of the panel frame, an oblique web beam 15 is connected between adjacent cross beams 16, and a "Z"-shaped structure or an inverse "Z"-shaped structure is formed between adjacent cross beams 16 and oblique web beams 15. The "Z"-shaped structure and the inverse "Z"-shaped structure are arranged alternately in sequence; the cover plate is arranged on the panel frame. In order to facilitate lifting and transportation, two lifting rings 1 are symmetrically arranged on the surface of the cover plate.

[0027] The frame includes columns 5 and diagonal braces 4. The columns 5 serve as the main vertical force-transmitting components of the frame, and their tops and bottoms are respectively connected to the protective panel 2 and the supports; one end of the diagonal brace 4 is connected to the end of the corresponding side of the protective panel 2, and the other end is connected to the middle of the columns 5. The columns 5, diagonal braces 4 and the protective panel 2 together form a triangular support system; in order to enhance the structural stability, vertical and diagonal webs 3 are arranged between the protective panel 2 and the diagonal braces 4, one end of the vertical web 3 is connected to the midpoint of the diagonal brace 4, and the other end is connected to the protective panel 2, one end of the diagonal web 3 is connected to the midpoint of the diagonal brace 4, and the other end is connected to the intersection of the protective panel 2 and the columns 5.

[0028] The clamp is installed on the column 5, and the installation height should be sufficient to clamp the frame at the upper corner of the passageway. The clamp includes a sleeve 8 and a stopper 9 that are slidably connected. The sleeve 8 is made of a square steel pipe, connected to the column 5, and has the same length as the width of the protective panel 2. The cross-sectional size is determined comprehensively according to the column 5 and the support model; the stopper 9 is made of a square steel pipe, and the cross-sectional size is adapted to the size of the sleeve 8. The length should be sufficient to exceed the distance between the passageways on both sides of the expansion joint after installation and clamp the frame. The clamp can be disassembled and installed according to the needs of hoisting and erection, which is convenient for hoisting and transportation while ensuring the stability of the safety protection device and preventing overturning.

[0029] Furthermore, the two inner side walls opposite to each other of the column 5 are provided with vertically extending sliding rails 20, and the clamping member is slidably matched with the sliding rails 20 through a sliding assembly; the part of the column 5 located above the bottom end of the diagonal support 4 is vertically spaced with a plurality of bolt holes, and the sliding assembly realizes sliding locking through bolts 13 assembled with bolt holes of corresponding heights. More specifically, the clamping member includes a sleeve 8 and a stopper 9 that are slidably connected, and the sliding assembly includes a connecting plate 19 fixedly connected to the sleeve, a pulley frame 17 fixedly connected to the connecting plate 19, and a pulley 18 rotatably assembled on the pulley frame 17, and the pulley 18 is slidably matched with the sliding rails 20, and the bolt 13 passes through the connecting plate 19 and is assembled and connected with the bolt holes of corresponding heights to realize the sliding locking of the sliding assembly. With this structural design, the height of the clamping member can be adjusted as needed to meet the clamping requirements of door openings of different heights.

[0030] The support is arranged at the bottom of the column 5, providing a basic fulcrum for the whole device, including a connection groove 6 and a support cross bar 7 which are slidably connected, and the connection groove 6 and the support cross bar 7 are locked by bolts 13. The connection groove 6 is made of channel steel, connected to the column 5, and its length is the same as the width of the protection panel 2, and the outer spacing of the two connection grooves 6 is the same as the width of the passage door opening; the support cross bar 7 is made of square steel, the model is adapted to the connection groove 6, and the length should be sufficient to exceed the distance between the passage door openings on both sides of the expansion joint after installation and support the frame firmly, and the two ends of the support cross bar 7 are respectively supported and connected with the completed floor surface 10 on both sides of the expansion joint.

[0031] In order to make the above technical solution clearer, a specific construction solution is provided below. Figure 1-9 As shown, a tool-type horizontal safety protection device for expansion joints of high-rise buildings is first made into a panel frame. The size of the panel frame should be determined according to the size of the expansion joint. Since the length of the expansion joint of the application project building is 9m and the width is 400mm, in this example, the outer dimensions of the panel frame are 9×0.3m in length×width. The panel frame uniformly adopts [12 channel steel, and the two longitudinal beams 14 are both 9m long with a net distance of 200mm. The cross beams 16 of the same type of channel steel are used at both ends to form a "mouth"-shaped frame. The channel steels are welded to each other, and the grooves are all facing the inside of the frame; in the middle of the "mouth"-shaped frame, a plurality of channel steels are arranged. Two cross beams 16, the spacing between the cross beams 16 is determined by the size of the door opening and the cross section of the support. In this example, the spacing between the two cross beams 16 in the middle of the "mouth"-shaped frame is 0.95m; then, two cross beams 16 are evenly arranged on both sides of the two middle cross beams 16, and the two ends of each cross beam 16 are welded firmly to the two longitudinal beams 14; to enhance the stability of the panel frame, the diagonal web beam 15 is welded between the cross beam 16 and the longitudinal beam 14 to form a "Z"-shaped structure or an inverse "Z"-shaped structure. Subsequently, in order to facilitate the safe passage of workers on the construction floor and the hoisting and transportation of protective devices, a 2mm thick steel plate is welded on the surface of the panel frame and two lifting rings 1 are set.

[0032] After the protective panel 2 is manufactured, the support frame is installed. Two columns 5 are welded on the two cross beams 16 in the middle of the panel frame. The columns 5 are made of [20 channel steel. To facilitate the installation of the web bars 3 and the diagonal braces 4, the grooves of the channel steel face the outside of the columns 5. The height of the columns 5 should be determined comprehensively based on the building floor height, the support height and the convenience of the construction layer operation. In this example, the height of the columns 5 is 2.7m; to facilitate the up and down movement of the clamps, vertically extending sliding tracks 20 are set on the two opposite inner walls of the columns 5, and the clamps are slidably matched with the sliding tracks 20 through the sliding assembly; the column 5 is located above the bottom end of the diagonal brace 4 and is vertically spaced with a plurality of bolt holes, and the sliding assembly is slidably locked by bolts 13 assembled with bolt holes of corresponding heights. More specifically, the clamp includes a sleeve 8 and a stopper 9 that are slidably sleeved, the sliding assembly includes a connecting plate 19 fixedly connected to the sleeve 8, a pulley frame 17 fixedly connected to the connecting plate 19, and a pulley 18 rotatably mounted on the pulley frame 17, the pulley 18 is slidably matched with a sliding track 20, the bolt 13 passes through the connecting plate 19 and is assembled and connected with a bolt hole of a corresponding height to achieve sliding locking of the sliding assembly; the sliding track 20 uses a small steel bar that is adapted to the size of the pulley 18. With this structural design, the height of the clamp can be adjusted as needed to meet the clamping requirements of door openings of different heights. A diagonal brace 4 is arranged between the column 5 and the protective panel 2. The diagonal brace 4 is made of [20 channel steel. One end of the diagonal brace 4 is welded to the crossbeam 16 at the end of the protective panel 2, and the other end is connected to the midpoint of the column 5. The column 5, the diagonal brace 4 and the protective panel 2 together form a triangular force system. In order to enhance the stability of the support frame, vertical and diagonal web members 3 are added inside the triangular force system. The web members 3 are made of [12 channel steel. One end of the vertical and diagonal web members 3 is welded to the midpoint of the diagonal brace 4, and the other end is respectively connected to the crossbeam 16 of the protective panel 2 and the top of the column 5.

[0033] Install the support at the bottom of the column 5. First, weld the connection groove 6 in the center of the bottom of the column 5. In this example, the connection groove 6 is made of [20 channel steel, the length of the channel steel is the same as the width of the protection panel 2, and the groove is facing downward; a support crossbar 7 is set up inside the connection groove 6. In this example, the support crossbar 7 is a square steel pipe with a cross-section length × height of 180 × 100mm. The length of the steel pipe should be able to exceed the outer edge of the door opening on both sides of the expansion joint after the installation is completed and support the safety protection frame firmly. In this example, the length of the support crossbar 7 is 1.2m; the connection groove 6 and the support crossbar 7 are locked by bolts 13.

[0034] After the support is installed, the clamping member is finally installed to prevent the safety protection device from tipping over during use. The sleeve 8 in the clamping member is rotatably assembled and connected to the sliding track 20 through the connecting plate 19, the pulley bracket 17, and the pulley 18 in sequence. The pulley 18 is a steel pulley with a diameter of 50 mm. The cross-sectional size and installation height of the sleeve 8 should be determined according to the size of the passage door opening, the type of the column 5, and the size of the support. In this example, the sleeve 8 is a square steel pipe with a cross-sectional length × height of 70 × 70 mm, and the installation height of the upper opening of the square steel pipe is at a position 2 m above the ground; a blocking rod 9 is inserted into the sleeve 8, and the cross-sectional size of the blocking rod 9 is adapted to that of the sleeve 8. In this example, the blocking rod 9 is a square steel pipe with a cross-sectional length × height of 60 × 60 mm, and the length of the steel pipe should be such that after installation, it exceeds the outer edges of the door openings on both sides of the expansion joint and clamps the safety protection frame tightly. In this example, the length of the blocking rod 9 is 1.2 m. During use, the height of the clamping member can be slidably adjusted as needed. After the height is positioned, the blocking rod 9, the sleeve 8, and the column 5 are locked with bolts 13 through the reserved bolt holes.

[0035] During use, the tool-type horizontal safety protection device for the expansion joint of high-rise buildings is hoisted and transported by a tower crane through two lifting rings 1 provided on the protection panel 2. After the hoisting is positioned, when the support is 0.5 m away from the supporting floor surface, the lowering stops. The supporting cross bar 7 is inserted into the connecting groove 6 and fixed with bolts 13. After the fixing is completed, the device is placed on the completed floor surface 10. Finally, the blocking rod 9 is inserted into the sleeve 8, and the height is slidably adjusted as needed. After the height is positioned, the blocking rod 9, the sleeve 8, and the column 5 are locked with bolts 13 through the reserved bolt holes to prevent the protection device from tipping over during use. To sum up, in this embodiment, a horizontal safety protection device for the expansion joint composed of a protection panel, a support frame, a clamping member, and a support is arranged at the expansion joint of high-rise buildings. The structure is simple and reliable, the operation is simple, it can be quickly installed, disassembled, hoisted, and transported according to the actual progress of the project. At the same time, it does not occupy other construction sites, is durable, easy to maintain, convenient to use, economical and practical, can be mass-produced, and is quickly promoted in the market. It can adapt to the situation where a passage and transfer channel need to be established below the expansion joint of the construction layer. It can not only protect the personnel passing below the expansion joint, but also provide safety protection for the construction personnel on the construction layer, eliminate potential safety hazards, and is particularly suitable for the construction of the expansion joint positions of high-rise buildings with wider expansion joints and higher floors.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that modifications or equivalent replacements of the technical solutions of the present invention, without departing from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
