Abstract
Description
Technical Field
[0001] The present application relates to the field of building technology, and in particular to a back rib and flue template system for preventing water seepage and smoke leakage in a flue. Background Art
[0002] In the field of construction, the application of aluminum alloy building formwork system is gradually becoming a trend. The system is made of integral extruded aluminum profiles as raw materials and is precision-processed. This formwork system has many significant advantages: first, the entire system is highly standardized, which can effectively ensure the quality and efficiency of construction; second, it is light in weight, easy to carry and install, and greatly reduces the labor intensity of construction workers; at the same time, the bearing capacity of aluminum alloy formwork is very strong, which can meet various complex construction needs. In addition, the formwork has high matching accuracy, which can ensure the close connection between the various components, thereby improving the integrity and stability of the construction. It is worth mentioning that this formwork can be recycled, which greatly reduces the construction cost and conforms to the concept of sustainable development. During the construction process, the aluminum alloy building formwork system does not require the assistance of mechanical equipment, which further simplifies the construction process and shortens the construction period. Because its construction process is clean and environmentally friendly, it will not generate construction waste and noise pollution, and the interference to the surrounding environment is minimized. When the concrete is poured, the concrete surface is flat and smooth after the formwork is removed, and no additional finishing is required, which not only improves the construction efficiency, but also ensures the appearance quality of the building.
[0003] The aluminum alloy formwork system also uses an advanced early dismantling system, which allows the formwork to be removed within 24 hours after the concrete building is poured, while the support system is retained until the third floor is constructed. This efficient construction method can achieve a construction progress of one floor every 4-5 days, greatly improving the construction efficiency of the building project, shortening the project cycle, and bringing significant economic benefits to the developer and the construction party. During the aluminum alloy formwork reinforcement construction process, most of the components can be assembled and disassembled safely and effectively on site. However, in some closed spaces with high vertical height and narrow working space, such as small hollow and closed components such as smoke exhaust shafts, the assembly and disassembly of the formwork cannot be carried out normally.
[0004] In the related technologies, the problem of smoke leakage and water seepage in the flue formwork system has always been a common headache, and the traditional flue construction method has many drawbacks. For example, there is a gap between the traditional flue and the structural floor slab, which requires secondary hanging hole treatment. However, the quality of the hanging hole is often difficult to guarantee, and it is easy to have hidden dangers of water seepage and smoke leakage. In addition, in the construction of traditional flues, the joints are usually disconnected at the unloading position of the floor slab steel support, and the gaps at the joints of the two flues against the wall are difficult to completely block. This leads to an increase in the original smoke leakage points and a great risk of smoke leakage. Judging from the smoke test results of previous projects, the effect of this traditional construction method is often unsatisfactory.
[0005] Due to the small space inside the flue, construction workers could not enter to install and remove the formwork, which brought great challenges to the construction. How to achieve one-time concrete forming of the flue, walls and floors, so as to improve production efficiency, assembly efficiency and project construction efficiency, reduce the tedious procedures of secondary construction, and reduce construction costs has become a problem that needs to be solved urgently.

[0037] After research, it was found that in the relevant technologies, the problem of smoke leakage and water seepage in the flue formwork system has always been a common headache, and the traditional flue construction method has many drawbacks. For example, there is a gap between the traditional flue and the structural floor, which requires secondary hanging hole treatment. However, the quality of the hanging hole is often difficult to guarantee, and it is easy to have hidden dangers of water seepage and smoke leakage. In addition, in the construction of traditional flues, the joints are usually disconnected at the unloading position of the floor steel support, and the gaps at the joints of the two flues against the wall are difficult to completely block. This leads to an increase in the original smoke leakage points and a great risk of smoke leakage. Judging from the smoke test results of previous projects, the effect of this traditional construction method is often unsatisfactory.
[0038] Due to the small space inside the flue, construction workers could not enter to install and remove the formwork, which brought great challenges to the construction. How to achieve one-time concrete forming of the flue, walls and floors, so as to improve production efficiency, assembly efficiency and project construction efficiency, reduce the tedious procedures of secondary construction, and reduce construction costs has become a problem that needs to be solved urgently.
[0039] See also Figure 1-6 , Figure 1-4 The structure diagram of the flue template system 1 in one embodiment of the present application is shown. Figure 5-6 The back rib 100 of one embodiment of the present application is shown in FIG. The back rib 100 for preventing water seepage and smoke leakage in a flue provided in one embodiment of the present application includes a mounting portion 110 and a limiting portion 120 .
[0040] The mounting portion 110 is disposed in the first cavity 12 of the flue main template 10, the bottom surface of the mounting portion 110 is disposed against the panel of the flue main template 10, and the upper edge of the mounting portion 110 does not exceed the side panel of the flue main template 10. At least two limiting portions 120 are provided, each of which is disposed at the upper edge of the mounting portion 110 and extends from the mounting portion 110 to both sides, the limiting portion 120 spans the side panel of the flue main template 10 and the side panels of the flue corner templates 20 adjacent to both sides, and the end of the limiting portion 120 can limit the flue corner template 20.
[0041] The back rib 100 and the flue template system 1 using the back rib 100, the mounting portion 110 is arranged in the first cavity 12 of the flue main template 10, and most of the back rib 100 structure is embedded in the main template, so that the back rib 100 is designed to be hidden, suitable for a narrower space, so that the template has a larger activity space, and is convenient for subsequent template disassembly. For example, it has been verified that under the same template size (the flue template system width is 400mm), Figure 1The maximum diameter of the flue area in the traditional flue template system is only 162 mm, while the maximum diameter of the flue area of the flue template system of the present application is 226 mm, which greatly improves the size of the flue area.
[0042] By designing the limiting part 120 structure, the flue corner template 20 is limited, the template is reinforced and prevented from being misaligned with each other, and the flue corner templates 20 on both sides are connected to the middle flue main template 10 as a whole; the back rib 100 can be formed in one piece, and the structure is simple and only requires a few components. Even if multiple parts are welded, it is easy to process and is more convenient for aluminum mold design and construction.
[0043] Integrated construction reduces secondary construction and can achieve one-time concrete forming of the flue, walls and floors, avoiding the tedious process of secondary construction, effectively reducing construction hazards, improving the safety and reliability of the building, and fundamentally solving the gap problem caused by secondary construction, effectively eliminating the hidden dangers of water seepage and smoke leakage; the above-mentioned back rib 100 and the flue template system 1 using the back rib 100 have a high degree of standardization and high matching accuracy, which can ensure the perfect fit of the flue with the walls and floors, avoid the generation of gaps, thereby effectively reducing smoke leakage points and improving construction quality; no mechanical equipment assistance is required during the construction process, there is no construction waste and noise pollution, it meets the national low-carbon emission reduction requirements, is friendly to the surrounding environment, and can be recycled, which not only reduces material costs, but also reduces the subsequent maintenance costs caused by water seepage and smoke leakage problems, bringing significant economic benefits to developers and construction parties.
[0044] The flue template system 1 includes a flue main template 10 and a flue corner template 20, and a plurality of flue main templates 10 are provided. The flue corner template 20 is arranged between adjacent flue main templates 10, and encloses a flue area 30 with the flue main templates 10. The flue main template 10 and the flue corner template 20 both include side panels, panels, end panels, and reinforcing ribs arranged transversely on the panels. The difference between the flue main template 10 and the flue corner template 20 lies in the shape of the panels. The panel of the flue main template 10 is straight, and the panel of the flue corner template 20 is L-shaped. The flue corner template 20 is a C-groove structure, which makes it easier to disassemble the flue main template 10. The side panels are erected on the two edges of the panel, and the end panels are erected on the other two edges of the panel. The side panels and the end panels enclose a chamber on the panel. The reinforcing ribs are arranged parallel to the end panels and perpendicular to the side panels, and a plurality of reinforcing ribs divide the chamber into a plurality of first chambers.
[0045] In one of the embodiments, the side panels of the flue main template 10 and the side panels of the flue corner template 20 are arranged at an angle, and the opening between the side panels of the flue main template 10 and the side panels of the flue corner template 20 is arranged toward the flue area 30, so as to facilitate the disassembly and assembly between the templates. Specifically, the bottom ends (the ends facing away from the flue area 30) of the side panels of the flue main template 10 and the side panels of the flue corner template 20 abut against each other, so that the template system is enclosed and closed, and the top ends (the ends facing the flue area 30) of the side panels of the flue main template 10 and the side panels of the flue corner template 20 are separated from each other to form the above-mentioned opening. Preferably, the angle between the side panels of the flue main template 10 and the side panels of the flue corner template 20 is 5-20°, and in particular can be 8°, 10°, or 12°.
[0046] In other embodiments, when the flue main template 10 is not provided with reinforcing ribs, the first chamber is enclosed by the side panels and the end panels on the panel.
[0047] In one embodiment, the back rib 100 is integrally formed, for example, by extrusion molding.
[0048] In one embodiment, the mounting portion 110 includes a bottom wall 111 and a side wall 112, the bottom wall 111 is arranged against the panel of the flue main template 10, the side wall 112 is upright on the bottom wall 111, the limiting portion 120 is arranged on the side wall 112, the side wall 112 is arranged toward the first cavity 12, and the edges of the side wall 112 and the bottom wall 111 are arranged against the side panel of the flue main template 10.
[0049] Specifically, the mounting portion 110 has a bottom wall 111, the length of which is less than or equal to the width of the first cavity 12 of the flue main template 10. When the length of the bottom wall 111 is less than the width of the first cavity 12 of the flue main template 10, the two ends of the bottom wall 111 have a certain gap with the side panels of the flue main template 10. When the length of the bottom wall 111 is equal to the width of the first cavity 12 of the flue main template 10, the two ends of the bottom wall 111 are set against the side panels of the flue main template 10. The first cavity 12 is defined as a grooved area surrounded by the side panels, panels and transverse reinforcing ribs of the flue main template 10. One side of the bottom wall 111 fits the panel of the flue main template 10 as the bottom surface of the mounting portion 110.
[0050] The installation part 110 is provided with at least one side wall 112. Specifically, the installation part 110 has two side walls 112, which are respectively arranged at two edges of the bottom wall 111 facing the end plate (or stiffener), so that the installation part 110 is integrally in a C shape or a U shape. The side wall 112 is perpendicular to the bottom wall 111, or the side wall 112 forms an angle with the bottom wall 111. The length of the side wall 112 is less than or equal to the width of the first cavity 12 of the main flue formwork 10. When the length of the side wall 112 is less than the width of the first cavity 12 of the main flue formwork 10, there is a certain gap between the two ends of the side wall 112 and the side plates of the main flue formwork 10. When the length of the side wall 112 is equal to the width of the first cavity 12 of the main flue formwork 10, the two ends of the side wall 112 abut against the side plates of the main flue formwork 10. The lengths of the side wall 112 and the bottom wall 111 may be different.
[0051] In one embodiment, the bottom wall 111 and the side wall 112 of the backing strip 100 are connected, for example, by welding. The side wall 112 may be integrally provided with the limiting part 120.
[0052] In other embodiments, there are multiple side walls 112. Except for the two side walls 112 arranged at the two edges of the bottom wall 111 facing the end plate (or stiffener), the remaining side walls 112 may be arranged at the edges of the bottom wall 111 facing the side plates, so that the installation part 110 is integrally in a square groove shape, etc.
[0053] In one embodiment, the bottom wall 111 is provided with first fixing holes 130 for connecting the panel, and first bolts are inserted through the first fixing holes 130. Correspondingly, through holes are provided on the main flue formwork 10. The first bolts pass through the first fixing holes 130 and the through holes of the main flue formwork 10 to connect the main flue formwork 10 and the bottom wall 111. The constructor operates the first screw 11 to control the disassembly and assembly of the main flue formwork 10. In this way, the first bolts can be screwed in from the outside and perform a tensioning against the installation part 110, thereby playing a role in reinforcement. First nuts may be sleeved on the first bolts to reinforce the connection of the first bolts, and the first nuts may be fixed on the bottom wall 111. When disassembling the formwork, first screw out the first bolts, then push the four-sided main flue formwork 10 towards the center of the flue area 30, then lift it up, and finally disassemble the easily detachable C-groove type flue corner formwork 20 at the corner, thus completing the formwork disassembly process.
[0054] In one embodiment, the side wall 112 is provided with a second fixing hole 140 for connecting the reinforcing rib of the flue main template 10, and the second fixing hole 140 is penetrated with a second bolt. Correspondingly, the reinforcing rib is provided with a through hole, and the second bolt passes through the second fixing hole 140 and the through hole of the reinforcing rib to connect the reinforcing rib and the back rib 100. The constructor operates the first screw rod 11 to control the assembly and disassembly of the flue main template 10. The second nut can be sleeved on the second bolt to reinforce the connection of the second bolt, and the second nut can be fixed to the side wall 112.
[0055] In one embodiment, the limiting portion 120 is horizontally arranged at the upper edge of the mounting portion 110, and the limiting portion 120 includes a portion docked with the mounting portion 110 and a portion extending out of the mounting portion 110. The portion of the limiting portion 120 docked with the mounting portion 110 increases the height of the mounting portion 110, and this portion exceeds the side plate of the flue main template 10. The portion of the limiting portion 120 extending out of the mounting portion 110 spans the side plate of the flue main template 10 and the side plates of the flue corner templates 20 adjacent to both sides. Specifically, the portion of the limiting portion 120 extending out of the mounting portion 110 extends all the way beyond the side plate of the flue corner template 20. Thus, when the flue main template 10 moves in the direction away from the flue area 30 under the action of the first bolt, the limiting part 120 can limit the flue main template 10 and the flue corner template 20 to be in the same position, tightly connected without misalignment. When the flue main template 10 moves in the direction of the flue area 30 under the action of the first bolt, the limiting part 120 will not limit the movement of the flue main template 10, and the flue main template 10 can be easily separated from the flue corner template 20.
[0056] In one embodiment, the difference between the length of the limiting portion 120 and the width of the flue main template 10 is 20-100 mm; and / or, the height of the limiting portion 120 is 5-50 mm. Specifically, the width of the flue main template 10 is 100-280 mm, and the length of the portion of the limiting portion 120 extending out of the flue main template 10 is 20-100 mm. Preferably, when the width of the flue main template 10 is 250 mm, the difference between the length of the limiting portion 120 and the width of the flue main template 10, that is, the length of the portion of the limiting portion 120 extending out of the flue main template 10 is 21.5 mm.
[0057] In one embodiment, the limiting portion 120 includes a horizontal edge 121 and a folded edge 122, the horizontal edge 121 abuts against the edge of the flue main template 10 and the edges of the flue corner templates 20 on both sides, the folded edge 122 is set at an angle to the horizontal edge 121, and the folded edge 122 extends into the second cavity of the flue corner template 20 to engage the flue main template 10 and the flue corner template 20.
[0058] Specifically, the groove area surrounded by the side panels, the panel and the end panels of the second cavity flue corner template 20. The horizontal edge 121 and the folded edge 122 are both parts of the limiting portion 120 extending out of the mounting portion 110, the folded edge 122 is set at an angle with the horizontal edge 121, and the bending direction of the folded edge 122 is toward the mounting portion 110. The bent folded edge 122 realizes the limitation of the flue corner template 20, and the length of the horizontal edge 121 is consistent with the sum of the thickness of the side panels of the flue main template 10 and the side panels of the flue corner template 20, so that the bending part of the folded edge 122 directly abuts against the side panels of the flue corner template 20 to limit in multiple directions.
[0059] In one embodiment, the angle α between the folded edge 122 and the transverse edge 121 is greater than or equal to 120°. Preferably, the angle α between the folded edge 122 and the transverse edge 121 can be 125°, 130°, 135°, 140°, 150°, etc.
[0060] In one embodiment, the limiting portion 120 includes a horizontal edge 121 and a connecting portion located at the end of the horizontal edge 121, the horizontal edge 121 abuts against the edge of the flue main template 10 and the edges of the flue corner templates 20 on both sides, and the connecting portion clamps the side panels of the flue main template 10 and the side panels of the flue corner template 20. Specifically, as an alternative to the above-mentioned folding edge 122, the connecting portion is a quick-release clamping structure, when the first screw 11 is pushed to make the flue main template 10 move toward the flue area 30, the connecting portion can be separated from the side panels of the flue main template 10 and the side panels of the flue corner template 20, otherwise the side panels of the flue main template 10 and the side panels of the flue corner template 20 are connected together.
[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0062] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
