Description

Technical Field

[0001] This invention relates to the field of building decoration construction, specifically to a method for constructing a prefabricated river-blocking ribbon and the river-blocking ribbon itself. Background Technology

[0002] A river barrier typically consists of railings, handrails, horizontal fences, and a base. The bottom of the barrier is connected to the ground, stairs, or other load-bearing surfaces via the base. Its functions generally include safety protection, separation, guidance, and decorative effect.

[0003] Existing technologies, such as the utility model patent with announcement number CN219451325U, disclose a building dam that includes a post-embedded plate, a keel, a base plate, and a decorative panel. The post-embedded plate is fixed to the wall surface by chemical anchors, and the following construction process is disclosed: installation of the post-embedded plate, installation of the keel, installation of the base plate, veneer application, and painting.

[0004] During construction, the upper elevation of the river-blocking ribbon is usually required to be consistent, while the installation elevation of the bottom of the keel is inconsistent due to the building's load-bearing base. The keel is usually custom-made and has basically the same specifications and dimensions. For large-area river-blocking ribbons, it may be necessary to trim, fill and weld the keel on-site, which increases the workload. Summary of the Invention

[0005] To address the elevation control issue caused by uneven building support surfaces during the construction of river-blocking strips, this invention provides a prefabricated river-blocking strip construction method and a river-blocking strip. By adjusting the frame structure, the elevation adjustment problem can be solved, and the stability after installation can be guaranteed, thus improving safety performance.

[0006] The technical objective of this invention is achieved through the following technical solution:

[0007] A method for constructing a prefabricated river-blocking ribbon, the river-blocking ribbon including a skeleton, a base plate, and a finishing layer; the skeleton includes several skeleton panels and transverse connecting sub-skeletons connecting the skeleton panels;

[0008] The skeleton sheet includes a first vertical skeleton, a second vertical skeleton, a third vertical skeleton, a first horizontal skeleton, a second horizontal skeleton, and a third horizontal skeleton;

[0009] One end of the first horizontal frame is vertically connected and fixed to the upper side of the first vertical frame. The other end of the first horizontal frame is provided with a vertical connecting frame perpendicular to the first horizontal frame. The lower side of the vertical connecting frame is connected to the upper side of the third vertical frame.

[0010] One end of the second horizontal frame is vertically connected and fixed to the side of the first vertical frame near the middle position. A height adjustment support is provided below the other end of the second horizontal frame, and the height of the height adjustment support is adjustable.

[0011] The second vertical frame is arranged parallel to one side of the first vertical frame, and the lower end of the second vertical frame is at the same elevation as the lower end of the first vertical frame; the second vertical frame extends upward to below the height of the middle of the first vertical frame; a reinforcing connecting frame connects the first vertical frame and the second vertical frame.

[0012] The third horizontal frame is fixed horizontally to the upper end of the second vertical frame, and the upper end of the second vertical frame is vertically fixed to the third horizontal frame.

[0013] A clamping space is formed between the height-adjustable support and the third transverse frame to clamp and fix it to the edge of the building's load-bearing base. The bottom of the height-adjustable support is connected to a metal anchor plate.

[0014] During construction, the frame pieces are processed into standard parts. The clamping space of the frame pieces is clamped to the edge of the building's load-bearing base. The metal anchor plate at the lower end of the height adjustment support is fixed to the upper surface of the building's load-bearing base with chemical anchors. The third transverse frame is fixed to the lower surface of the building's load-bearing base with chemical anchors. After the frame pieces are connected together by transverse connecting sub-frames, a base plate is installed on the outside of the frame, and the decorative surface is made on the surface of the base plate.

[0015] Furthermore, the height adjustment support includes a first support and a second support. The upper end of the first support is vertically fixed to the second transverse frame, and the lower end of the second support is vertically fixed to the upper surface of the metal anchor plate at the bottom of the height adjustment support. The lower end of the first support and the upper end of the second support are connected by a socket joint. A vertically arranged height adjustment hole is provided at the position where the first support and the second support are connected by a socket joint, and a fastening bolt is inserted into the height adjustment hole.

[0016] Furthermore, the installation positions of the frame pieces are determined according to the extended shape of the river-blocking ribbon. When installing the frame pieces, the clamping space is clamped at the edge of the building's load-bearing base. The height of the height adjustment support is adjusted. During the adjustment process, the elevation of the upper surface of the first transverse frame is measured until the elevation of the upper surface of the first transverse frame reaches the design height. The metal anchor plate at the bottom of the height adjustment support is fixed to the upper surface of the building's load-bearing base with chemical anchors. Then, the third transverse frame is fixed to the lower surface of the building's load-bearing base with chemical anchors.

[0017] Furthermore, an accommodating space is formed between the first horizontal frame, the second horizontal frame, the first vertical frame, and the third vertical frame of the adjacent skeleton pieces. An air conditioner is installed in the accommodating space, and an upper air vent is installed above the accommodating space. When the base plate is installed at the upper end of the accommodating space, space is left for the installation of the upper air vent. After the base plate is installed, the upper air vent is embedded in the first horizontal frame.

[0018] Furthermore, one end of the vertical connecting frame of the first horizontal frame is aligned vertically with the third vertical frame, and the vertical connecting frame forms a concave space between the upper ends of the first horizontal frame and the third vertical frame; after the frame is installed, a U-shaped light trough is installed in the concave space, and the sides of the U-shaped light trough are covered by the base plate; a light strip is installed in the U-shaped light trough.

[0019] Furthermore, the lower end of the third vertical frame is left with a gap of one end from the second horizontal frame, and the length of the second horizontal frame is shorter than the length of the first horizontal frame; base plates are installed on the side of the height adjustment support and the side of the third vertical frame respectively, and the base plates on the side of the height adjustment support and the side of the third vertical frame are staggered and overlapped near the lower end of the third vertical frame, and a lower air vent is set at the position where the base plates are staggered and overlapped, and the lower air vent is fixed on the base plate.

[0020] Furthermore, the decorative surface is processed onto the baseboard using electrostatic powder coating, wood grain transfer printing, or wood veneer pasting.

[0021] Furthermore, the base plate is a honeycomb aluminum plate, which includes a surface aluminum plate and a honeycomb plate, with the honeycomb plate sandwiched between the surface aluminum plates on both sides; the finishing layer is processed on the outer surface aluminum plate; after the finishing layer is processed on the surface aluminum plate, it is installed together with the base plate.

[0022] The present invention also provides a prefabricated river-blocking ribbon, which includes a skeleton, a base plate, and a finishing layer, constructed according to the above method. The skeleton pieces are distributed sequentially along a straight line or a curve, and the transverse connecting sub-skeletons between the skeleton pieces have the same linear shape as the distribution of the skeleton pieces.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. The prefabricated river-blocking ribbon of this invention, through the processing of the skeleton panels, can be made into standard parts for on-site assembly and installation, reducing on-site welding workload and improving installation efficiency. Since the skeleton panels are processed into standard parts, unevenness of the building's supporting surface during on-site installation can make it difficult to control the top elevation of the installed panels. This invention uses height-adjustable supports to ensure that the top elevation of the installed skeleton panels remains consistent, reducing on-site cutting or repair work. Furthermore, it avoids the problem of low skeleton precision caused by on-site cutting; excessive cutting errors lead to material waste, and the quality of welds cannot be guaranteed during welding.

[0025] 2. The skeleton of the present invention forms a clamping space between the height adjustment support and the third transverse skeleton for clamping and fixing to the edge of the building load-bearing base. During installation, it is clamped to the edge of the building load-bearing base from the top and bottom sides. Compared with the traditional skeleton form, it is more stable and safer. It is not affected when the edge of the building load-bearing base does not have an upper or lower convex edge, thus improving adaptability.

[0026] 3. The first horizontal frame, the second horizontal frame, the first vertical frame, and the third vertical frame of the adjacent frame pieces form an accommodating space. The air conditioner is installed in the accommodating space, which improves the utilization of space. After the base plate is installed, the air conditioner is hidden behind the base plate, which enhances the aesthetics of the river-blocking ribbon. Attached Figure Description

[0035] The technical solution of the present invention will be further described below with reference to specific embodiments:

[0036] A method for constructing a prefabricated river-blocking ribbon, the river-blocking ribbon comprising a frame, a base plate, and a finishing layer; the finishing layer is processed on the base plate, the base plate is installed on the outside of the frame, and the frame is installed and fixed at the edge of the building's load-bearing base.

[0037] Specifically, such as Figure 7 As shown, the skeleton includes several skeleton pieces 23 and transverse connecting sub-skeletons 24 connected between the skeleton pieces 23. The transverse connecting sub-skeletons 24 are welded to the skeleton pieces 23, or they can be assembled using bolts or the like. The skeleton pieces 23 are arranged sequentially along the extension shape of the river-blocking ribbon. If the river-blocking ribbon has a straight line shape, several skeleton pieces are distributed sequentially at intervals along the straight line shape, and the skeleton pieces are connected to each other by the transverse connecting sub-skeletons 24 of the straight line shape. If the river-blocking ribbon has a curved line shape, the skeleton pieces are distributed sequentially at intervals along the curved line shape of the river-blocking ribbon, and the skeleton pieces are connected to each other by the transverse connecting sub-skeletons 24 of the same line shape as the corresponding position of the river-blocking ribbon.

[0038] More specifically, the skeleton panels are fabricated as standard parts outside the construction site and then assembled on-site. Each skeleton panel has the same structure, such as... Figures 1-3 As shown, it includes:

[0039] First vertical frame 1, second vertical frame 2, third vertical frame 3, first horizontal frame 4, second horizontal frame 5, third horizontal frame 6;

[0040] One end of the first horizontal frame 4 is vertically connected and fixed to the upper side of the first vertical frame 1. The other end of the first horizontal frame 4 is provided with a vertical connecting frame 7 perpendicular to the first horizontal frame 4. The lower side of the vertical connecting frame 7 is connected to the upper side of the third vertical frame 3.

[0041] One end of the second horizontal frame 5 is vertically connected and fixed to the side above the middle position of the first vertical frame 1. The second horizontal frame 5 and the first horizontal frame 4 are located on the same side of the first vertical frame 1. A height adjustment support is provided below the other end of the second horizontal frame 5. The height of the height adjustment support is adjustable.

[0042] The second vertical frame 2 is arranged parallel to one side of the first vertical frame 1. All structures on the frame body other than the first vertical frame 1 are located on the same side of the first vertical frame 1. The lower end of the second vertical frame 2 is at the same elevation as the lower end of the first vertical frame 1. The second vertical frame 2 extends upward to below the height position close to the middle of the first vertical frame 1. A reinforcing connecting frame 8 connects the first vertical frame 1 and the second vertical frame 2.

[0043] The third transverse frame 6 is horizontally fixed to the upper end of the second vertical frame 2, and the upper end of the second vertical frame 2 is vertically fixed to the third transverse frame 6; preferably, an inclined support is also provided between the second vertical frame 2 and the third transverse frame 6.

[0044] A clamping space is formed between the height-adjustable support and the third transverse frame 6 to clamp and fix it to the edge of the building's load-bearing base 9. The bottom of the height-adjustable support is connected to a metal anchor plate 10.

[0045] The skeleton panels can be welded into standard parts at the factory stage or on site. A uniform template can be made as a reference for welding positioning to achieve mass production. After processing, the clamping space of the skeleton panel is clamped at the edge of the building bearing base 9. The metal anchor plate 10 at the lower end of the height adjustment support is fixed to the upper end of the building bearing base 9 with chemical anchors. The third transverse skeleton 6 is fixed to the lower end of the building bearing base 9 with chemical anchors. After the skeleton panels are connected together by transverse connecting sub-skeletons, the base plate 11 is installed on the outside of the skeleton, and the decorative surface is made on the surface of the base plate 11.

[0046] In one embodiment, such as Figure 4 As shown, the height-adjustable support includes an upper support 12 and a lower support 13. The upper support 12 is connected to the second transverse frame 5, and the lower support 13 is connected to the metal anchor plate 10. A double-ended bolt 14 is connected between the upper support 12 and the lower support 13. The two ends of the double-ended bolt 14 are threadedly connected to the upper support 12 and the lower support 13, respectively. The height of the height-adjustable support can be adjusted by rotating the double-ended bolt 14 to adjust the distance between the upper support 12 and the lower support 13.

[0047] Compared to the height-adjustable support described above, another embodiment employs a more easily manufactured structural form, such as... Figure 5As shown, the height-adjustable support includes a first support 15 and a second support 16. The upper end of the first support 15 is vertically fixed to the second transverse frame 5, and the lower end of the second support 16 is vertically fixed to the upper surface of the metal anchor plate 10 at the bottom of the height-adjustable support. The lower end of the first support 15 and the upper end of the second support 16 are connected by a socket joint. A vertically arranged height-adjustable hole 17 is provided at the position where the first support 15 and the second support 16 are connected by a socket joint, and a fastening bolt 18 passes through the height-adjustable hole 17. In this embodiment, the lower end of the first support 15 is fitted onto the upper end of the second support 16, and after the height adjustment is completed, it is tightened and fixed by the fastening bolt 18.

[0048] In another embodiment, the height of the third transverse frame can also be adjusted by a height-adjusting support. The height-adjusting support can be set between the third transverse frame and the second vertical frame to adjust the height of the third transverse frame so that the third transverse frame can fit tightly against the lower end of the building's load-bearing base.

[0049] During the installation of the frame, the installation position of each frame piece is determined according to the extended shape of the river-blocking ribbon. The frame pieces are installed one by one at the installation position on the building's load-bearing base. During installation, all frame pieces can be installed first and then the transverse connecting sub-frames can be installed. Alternatively, after two frame pieces are installed, the transverse connecting sub-frames between the two frame pieces can be installed, and then the next frame piece and the transverse connecting sub-frames between the frame pieces can be installed.

[0050] During the installation of each frame piece, the clamping space is clamped to the edge of the building load-bearing base 9. The height of the height adjustment support is adjusted, and the elevation of the upper surface of the first transverse frame is measured during the adjustment process. The height adjustment is stopped when the elevation of the upper surface of the first transverse frame reaches the design height. The metal anchor plate 10 at the bottom of the height adjustment support is fixed to the upper surface of the building load-bearing base 9 with chemical anchors. Then, the third transverse frame 6 is fixed to the lower surface of the building load-bearing base 9 with chemical anchors. After installation, there may be gaps between the metal anchor plate on the third transverse frame 6 and the building load-bearing base, which can be filled with foam material.

[0051] The elevation of the upper surface of the first transverse frame can be detected by using a total station in conjunction with a reflector. Alternatively, a horizontal laser instrument can be used to project a horizontal laser line at the elevation position, and the elevation of the upper surface of the frame can be adjusted to the height of the horizontal laser line.

[0052] As a preferred option, such as Figure 7As shown, the air conditioner 19 can also be installed inside the river-blocking ribbon. The river-blocking ribbon where the air conditioner is installed is selected in a straight-line area. Specifically, an accommodating space is formed between the first horizontal frame 4, the second horizontal frame 5, the first vertical frame 1, and the third vertical frame 3 of the adjacent frame pieces 23. The air conditioner is installed in the accommodating space, and an upper air vent 20 is installed above the accommodating space. When installing the base plate 11 at the upper end of the accommodating space, space is reserved for the installation of the upper air vent 20. After the base plate is installed, the upper air vent 20 is embedded in the first horizontal frame 4. The upper air vent 20 is a metal grille vent with a rectangular outer frame and several grille strips installed in the rectangular outer frame. The structure of the lower air vent 22 is the same as that of the upper air vent 20.

[0053] The first horizontal frame 4 has one end of the vertical connecting frame 7 aligned vertically with the third vertical frame 3. The vertical connecting frame 7 forms a concave space between the upper ends of the first horizontal frame 4 and the third vertical frame 3. After the frame is installed, a U-shaped light trough 21 is installed in the concave space. The sides of the U-shaped light trough 21 are covered by the base plate 11, and a light strip is installed in the U-shaped light trough 21. Specifically, holes are drilled in the vertical connecting frame 7, and the U-shaped light trough 21 and the vertical connecting frame 7 are connected by screws through the holes in the vertical connecting frame 7.

[0054] Preferably, the lower end of the third vertical frame 3 is left with a gap of one end from the second horizontal frame 5, and the length of the second horizontal frame 5 is shorter than the length of the first horizontal frame 4. Base plates 11 are installed on the sides of the height adjustment support and the third vertical frame 3, respectively. The base plates 11 on the side of the height adjustment support and the side of the third vertical frame 3 are staggered and overlapped near the lower end of the third vertical frame 3. A lower air vent 22 is set at the staggered overlap position of the base plates 11, and the lower air vent 22 is fixed to the base plates 11. The distance between the staggered and overlapping base plates 11 is the width of the lower air vent 22. Specifically, the two sides of the lower air vent 22 are respectively connected and fixed to the base plates 11 on the side of the height adjustment support and the third vertical frame 3 using screws, bolts, etc.

[0055] The base plate 11 is preferably a honeycomb aluminum plate, which includes two layers of aluminum plates and a honeycomb plate sandwiched in the middle. The honeycomb aluminum plates are bonded together. The honeycomb plate is like a honeycomb cardboard. During installation, the aluminum plate on one side is closer to the frame and is the inner aluminum plate, while the aluminum plate on the other side is the outer aluminum plate. The finishing layer is processed on the outer aluminum plate and can be processed in the form of electrostatic powder coating, wood grain transfer, or wood veneer. The finishing layer is then installed together with the honeycomb aluminum plate.

[0056] At the corner, the edges of the baseboard are beveled at a 45-degree angle. The baseboards at the corner are joined together using the 45-degree bevel to form a right-angle corner. Right-angle brackets are installed on the inner side of the corner of the baseboard for reinforcement. Figure 6 As shown. The baseboard can be fixed with screws or installed by dry hanging to avoid damaging the decorative layer on the outer aluminum panel.

[0057] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. Those skilled in the art can make non-inventive modifications to this embodiment as needed after reading this specification, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
