Description

Technical Field

[0001] This invention relates to the field of steel structure technology, and in particular to a fireproof steel structure for buildings and its manufacturing process. Background Technology

[0002] When constructing large buildings, many fire-resistant steel structures are often used in combination, which allows the steel structure to have excellent fire resistance while in use.

[0003] When existing fire-resistant steel structures are used, the temperature of the steel structure may become too high in some areas during water filling for fireproofing, which will reduce the fireproofing effect. In addition, water filling can cause the steel structure to become hollow, which will affect the strength of the steel structure and make it prone to bending after long-term use. Furthermore, when connecting steel structures, pads are required for centering installation, but the use of pads is not stable enough and poses a safety hazard. Summary of the Invention

[0004] In view of this, the present invention provides a fireproof steel structure for buildings and its process, in order to solve the problem that when existing fireproof steel structures are used and filled with water for fireproofing, the local temperature of the steel structure is easily too high, which leads to a decrease in the fireproofing effect.

[0005] This invention provides a fire-resistant steel structure for buildings and its manufacturing process, specifically including: a steel component; the steel component is the main body of the steel structure, and the interior of the steel component has a water-filled inner cavity, which is a rectangular structure. The water-filled inner cavity has evenly arranged inner partitions, which are also rectangular and made of wax. Each inner partition has two triangular grooves on its two sides and two circular holes in its center; and mounting components, which are rectangular and made of metal, and are evenly arranged and installed on the top of the steel component. Each mounting component has two ends... Each component has a mounting plate, and a support head with a wedge-shaped structure is fixed to its top. Two support heads are symmetrically arranged. There are also two fixing heads, each with an I-shaped structure and made of metal. These two fixing heads are fixed to both ends of the steel component. Each fixing head has two through slots at its bottom, and a support member with a U-shaped structure and made of metal is inserted into each slot. Each support member has a pressure groove on both sides, with the grooves being inclined and having arc-shaped ends.

[0006] Optionally, the top of the water-filled inner cavity is provided with uniformly arranged liquid inlets, which are rectangular in structure. Each liquid inlet is located between two inner partitions. The top of the steel component is provided with uniformly arranged connecting slots on both sides, which are rectangular in structure. Each inner partition has a pressing component fixed through it. The pressing component is U-shaped and made of metal. Each pressing component has a downward pressure guide groove at both ends of its bottom, which is wedge-shaped.

[0007] Optionally, each mounting component has a fixed plug at its bottom. The plug is rectangular and is inserted into the filling port. Each plug has an embedded groove at its bottom, which is arc-shaped. An embedded head is fixed inside each embedded groove. The embedded head is arc-shaped and made of flexible rubber. A sealing element is fixed at the bottom of each embedded head. The sealing element is U-shaped and made of flexible rubber. Each sealing element has evenly arranged arc-shaped grooves on both sides. The sealing element is inserted into the filling port along with the plug. The mounting plate has an inverted U-shaped structure and is made of metal. The bottom of the mounting plate is inserted into the connecting slot. An auxiliary rod is fixed between every two support heads. The auxiliary rod is rectangular and made of metal.

[0008] Optionally, each of the fixing heads has a groove at its inner bottom end. The groove is a long strip with arc-shaped ends and a rectangular through groove. An adjusting component is fixed to the upper sides of each fixing head. The sides of the adjusting component are bolts, and a nut is fitted onto the outside of each adjusting component. Each fixing head has a long groove at its inner top end. A movable plate is slidably inserted into the inside of each long groove. The movable plate is an I-shaped plate. A side rod is fixed to each side of each movable plate. The side rod is rectangular and made of metal. A pressure rod is fixed between every two side rods. The pressure rod is cylindrical and made of metal. The pressure rod is inserted into both the pressure groove and the groove.

[0009] Optional, the following steps may be included:

[0010] 01. First, control the welding and fixing of the two fixing heads to both ends of the steel component, and then evenly apply fireproof coating to the outside of the steel component;

[0011] 02. Control the addition of waterproof coating to the inside of the water-filled cavity until the filling port is full of waterproof coating. Then control the steel component to be inverted and then temporarily fix the steel component so that the waterproof coating inside the water-filled cavity can be continuously discharged by inertia, so that the inside of the water-filled cavity can be evenly coated with a layer of waterproof coating. At the same time, the discharged waterproof coating can be reused.

[0012] 03. Control the inner partition and the pressing component to be inserted into the water-filled inner cavity through the liquid filling port, so that the inner partition can automatically fit into the water-filled inner cavity and thus be inside the water-filled inner cavity, separating the water-filled inner cavity;

[0013] 04. Then add water through the filling port in sequence, so that the water can be inside the water-filled inner cavity and at the side of the inner partition;

[0014] 05. Then, control the installation component to be installed on the top of the steel component so that the plug can be inserted into the inside of the liquid filling port together with the seal, so that the rubber seal can be squeezed and sealed, thereby improving the sealing effect and preventing the water inside the water-filled cavity from leaking or evaporating. This completes the process of the device.

[0015] The beneficial effects are:

[0016] 1. By setting up an internal partition, when the steel structure becomes locally hot after a fire, the high temperature will be transferred to the internal partition. Since the internal partition is made of wax, it can melt quickly when heated, allowing the water on the side of the internal partition to connect together and neutralize the water. This will lower the temperature of the locally hot water. At the same time, after the internal partition melts, the pressing component can move downward by gravity, which will push the water outward through the downward pressure guide groove to mix, thereby improving the neutralization efficiency and allowing the water temperature to mix and drop, avoiding excessively high local temperatures.

[0017] 2. By setting up support heads, this device can be used at the top of the steel structure after multiple mounting parts are spliced ​​together. This allows the plug and seals to be inserted into the liquid filling port for sealing, thereby improving the sealing effect and preventing water evaporation and leakage inside the water-filled cavity. At the same time, two adjacent support heads can be spliced ​​together to support the steel structure at the top, thereby helping to improve the strength of the steel structure. When the steel structure is under stress, the support heads can support the steel structure, preventing it from bending downwards and extending its service life.

[0018] 3. By setting up support components and pressure grooves, when the fixed head needs to be connected in a centered manner during use, the nut can be manually controlled to rotate outside the adjusting component, thereby moving using the thread. As the nut moves, it can push the moving plate to move, which in turn moves the pressure rod. The pressure rod is guided to move within the sliding groove and pressure groove. Since the pressure groove is an inclined structure, while the pressure rod moves laterally within it, the support component moves downward, thereby lifting the outer end of the fixed head and steel component. This allows the fixed head to be adjusted in height, enabling centered installation and improving stability. Attached Figure Description

Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0035] Example: Please refer to Figures 1 to 8 As shown:

[0036] This invention provides a fire-resistant steel structure for buildings and its manufacturing process, including a steel component 1; the steel component 1 is the main body of the steel structure, and the interior of the steel component 1 is provided with a water-filled inner cavity 101. The water-filled inner cavity 101 has a rectangular structure and can be filled with water, thereby allowing the steel component 1 to maintain a low temperature during a fire. The interior of the water-filled inner cavity 101 is provided with uniformly arranged inner partitions 104. The inner partitions 104 have a rectangular structure and are made of wax, which can melt after being heated, thereby allowing the water to mix automatically. Two triangular grooves are provided on each side of the inner partitions 104, and two round holes are provided in the middle of the inner partitions 104, which can allow the inner partitions 104 to melt quickly after being heated. Mounting components 2 are rectangular structures and made of metal. The mounting components 2 are uniformly arranged and installed on the top of the steel component 1. Each mounting component 2 has a mounting plate 205 fixed at both ends, and a support head 206 fixed at the top of each mounting plate 205. The support head 206 has a wedge-shaped structure, and every two support heads 206 are symmetrically arranged, which can be installed on the mounting components. 2. After splicing, it is used at the top of steel component 1 to assist in supporting steel component 1, preventing it from bending downwards under stress, thus improving its service life and strength; Fixing head 3, which is an I-beam structure, can be fixed to both ends of steel component 1, driving steel component 1 to be fixed together. Fixing head 3 is made of metal, and there are two fixing heads 3, which are fixed to both ends of steel component 1 respectively. Each fixing head 3 has two through slots 302 at its bottom, and each through slot 302 is into which a [missing information - likely a component or part]. A support member 304 is U-shaped and can be positioned at the bottom of the fixing head 3 for height adjustment, thereby allowing the fixing head 3 to be fixed in the center. The support member 304 is made of metal, and each support member 304 has a pressure groove 305 on both sides. The pressure groove 305 has an inclined structure and arc-shaped ends, allowing the pressure rod 308 to be guided and displaced within it. This facilitates the control of the height adjustment of the support member 304, thereby allowing the fixing head 3 to be installed and used in the center, improving the convenience of connection.

[0037] refer to Figure 5The top of the water-filled inner cavity 101 is provided with uniformly arranged liquid inlets 102. The liquid inlets 102 are rectangular in structure, allowing water to be added through them, thus enabling water to be stored and used inside the water-filled inner cavity 101. Each liquid inlet 102 is located between two inner partitions 104. The top of the steel component 1 is provided with uniformly arranged connecting slots 103 on both sides. The connecting slots 103 are rectangular in structure, used to insert and fix the mounting plate 205, thereby driving the mounting component 2 to be securely installed and used. A pressing component is fixedly fixed through the interior of each inner partition 104. 105 can be installed and used together with the inner partition 104. The pressure member 105 has a U-shaped structure and is made of metal. After the inner partition 104 melts, the pressure member 105 can be moved downward by gravity. Each pressure member 105 has a downward pressure guide groove 106 at both ends of its bottom. The downward pressure guide groove 106 has a wedge-shaped structure. After the pressure member 105 moves downward under force, it can promote the water mixing and flow through the downward pressure guide groove 106, thereby improving the mixing effect and allowing the water to be quickly neutralized and cooled, avoiding the phenomenon of local high temperature in the steel component 1.

[0038] refer to Figure 6 and Figure 7 Each mounting component 2 has a fixed plug 201 at its bottom. The plug 201 has a rectangular structure and is inserted into the liquid inlet 102 for sealing. Each plug 201 has an embedded groove 202 at its bottom, which is arc-shaped and used to embed and fix an embedded head 203. An embedded head 203, also arc-shaped and made of flexible rubber, is embedded and fixed inside each groove 202. Each embedded head 203 has a fixed sealing element 204 at its bottom. The sealing element 204 has a U-shaped structure and is also made of flexible rubber, allowing it to be compressed for sealing, thus improving the sealing effect and preventing water evaporation. To prevent leakage, each seal 204 has evenly arranged arc-shaped grooves on both sides to assist in sealing and improve the sealing effect. The seal 204 is inserted into the liquid inlet 102 along with the plug 201. The mounting plate 205 has an inverted U-shaped structure and is made of metal. The bottom of the mounting plate 205 is inserted into the connection slot 103, which can be easily installed and used with the mounting component 2. An auxiliary rod 207 is fixed between every two support heads 206. The auxiliary rod 207 has a rectangular structure and is made of metal. It can be fixed between the two support heads 206, which facilitates the handling and control of the movement of the mounting component 2. At the same time, it can be placed inside the two support heads 206 to increase the support strength and reduce the probability of the steel component 1 bending.

[0039] refer to Figure 8Each fixed head 3 has a groove 301 at its inner bottom. The groove 301 is a long strip structure with arc-shaped ends, allowing the pressure rod 308 to be guided and displaced within it, thus facilitating the movement of the support member 304. The through groove 302 is a rectangular structure, allowing the support member 304 to slide freely within it, thus facilitating the adjustment of the position of the fixed head 3 and ensuring that the fixed head 3 can be installed and connected in a centered position. Each fixed head 3 has an adjusting member 303 fixed on its upper sides. The sides of the adjusting member 303 are bolt structures, and a nut is fitted on the outside of each adjusting member 303, allowing the nut to rotate outside the adjusting member 303 and thus freely adjust its position. Each fixed head 3 has a long groove at its inner top, and a movable plate 306 is slidably inserted into the inside of each long groove. The movable plate 306 is an I-shaped plate. The movable plate 306 has a circular hole on each side, into which an adjusting member 303 is inserted. Rotating the nut allows the movable plate 306 to be easily moved, thus facilitating position adjustment. Each movable plate 306 has a rectangular side rod 307 fixed to each side, supporting the pressure rod 308 for improved ease of use and movement. The side rods 307 are made of metal. A pressure rod 308 is fixed between every two side rods 307. The pressure rod 308 is cylindrical and made of metal, inserted into both the pressure groove 305 and the sliding groove 301. It can slide within these grooves while receiving force, facilitating movement and adjustment of the support member 304.

[0040] Optional, the following steps may be included:

[0041] 01. First, control the two fixing heads 3 to be welded and fixed to both ends of the steel component 1, and then apply fireproof coating evenly to the outside of the steel component 1;

[0042] 02. Control the addition of waterproof coating to the inside of the water-filled inner cavity 101 until the waterproof coating fills the liquid inlet 102. Then control the steel component 1 to be inverted and then temporarily fix the steel component 1 so that the waterproof coating inside the water-filled inner cavity 101 is continuously discharged by inertia, so that a layer of waterproof coating can be evenly applied to the inside of the water-filled inner cavity 101. At the same time, the discharged waterproof coating can be reused.

[0043] 03. Control the inner partition 104 and the pressing member 105 to be inserted into the water-filled inner cavity 101 through the liquid filling port 102, so that the inner partition 104 can automatically fit into the water-filled inner cavity 101 and thus be inside the water-filled inner cavity 101, separating the water-filled inner cavity 101.

[0044] 04. Then, water is added sequentially through the liquid inlet 102 so that the water can be inside the water-filled inner cavity 101 and at the same time on the side of the inner partition 104.

[0045] 05. Then, control the installation component 2 to be installed on the top of the steel component 1 so that the plug 201 can be inserted into the inside of the liquid filling port 102 together with the seal 204, so that the rubber seal 204 can be squeezed and sealed, thereby improving the sealing effect and preventing the water inside the water filling cavity 101 from leaking or evaporating. Thus, the process of the device is completed.

[0046] The specific usage and function of this embodiment are as follows: In this invention, firstly, two fixing heads 3 are welded and fixed to both ends of the steel component 1. Then, fireproof coating is evenly applied to the outside of the steel component 1. Next, waterproof coating is added to the inside of the water-filled inner cavity 101 until the waterproof coating fills the liquid inlet 102. Then, the steel component 1 is inverted and temporarily fixed, so that the waterproof coating inside the water-filled inner cavity 101 is continuously discharged by inertia, so that a layer of waterproof coating can be evenly applied to the inside of the water-filled inner cavity 101. At the same time, the discharged waterproof coating can be reused. Then, the inner partition 104 and the pressing member 105 are inserted into the inside of the water-filled inner cavity 101 through the liquid inlet 102, so that the inner partition 104 can automatically fit into the water-filled inner cavity. 101, which is located inside the water-filled inner cavity 101, divides the water-filled inner cavity 101, and then water is added sequentially through the liquid inlet 102, so that the water can be inside the water-filled inner cavity 101 and on the side of the inner partition 104. Then, the mounting piece 2 is installed on the top of the steel component 1, so that the plug 201 can be inserted into the liquid inlet 102 together with the seal 204, and at the same time, the bottom end of the mounting plate 205 is inserted into the connection slot 103, so that the mounting piece 2 can be positioned and used, so that the rubber seal 204 can be squeezed and sealed, improving the sealing effect, so that the water inside the water-filled inner cavity 101 will not leak or evaporate. After multiple mounting pieces 2 are spliced ​​together, two adjacent support heads 206 can be brought into contact together, and then To improve the support effect, the steel component 1 is positioned at the top to increase its strength, preventing bending under stress and extending its service life. The steel component 1 is then installed and connected, allowing the fixing head 3 to connect to the installation position. A wrench is used to manually rotate the nut, which then moves the moving plate 306, quickly adjusting its position. This movement of the moving plate 306 moves the side rod 307 and the pressure rod 308 simultaneously. The pressure rod 308 is guided within both the pressure groove 305 and the sliding groove 301. Because the pressure groove 305 is inclined, the pressure rod 308, after moving within it, can press down on the support component 30. 4. Move downwards so that the bottom of the support 304 can contact the installation position, thereby pushing the fixing head 3 upwards. This allows the fixing head 3 to be freely adjusted in height and centered for connection. Then, control bolts are used to install and connect the fixing head 3. When this device is in use, in the event of a fire, the fire-retardant coating can improve the fire resistance. When the steel component 1 experiences localized high temperatures, the high temperature will be transferred to the inner partition 104. Since the inner partition 104 is waxy, it melts quickly when heated, allowing the water on the side of the inner partition 104 to connect together, thereby neutralizing the water and lowering the temperature of the locally hot water. Simultaneously, after the inner partition 104 melts, the pressing component 105 can move downwards using gravity.By pushing water outward through the downward guide channel 106, the neutralization efficiency is improved, allowing the water temperature to decrease through mixing, thus preventing excessively high local temperatures and a decrease in the local strength of the steel component 1.
