Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a fireproof steel structure for buildings. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. When existing steel structures are used in large rectangular buildings, stadiums, and high-rise buildings, fire-resistant structures, i.e., fire-resistant steel structures, are usually installed.

[0003] As disclosed in the prior art, patent CN221309406U discloses a fireproof steel structure for buildings. In the event of a fire, an electric push rod moves a support rod, which in turn moves a fixed pipe, nozzle, connecting rod, and water pipe toward the slot. The connecting rod abuts against a baffle and pushes the baffle. The connecting rod moves along the baffle, and the baffle rotates along the fixed rod. At this time, the torsion spring deforms, and the baffle no longer obstructs the slot. The nozzle and connecting rod pass through the slot and are located outside the steel structure. The water pump then delivers water from the tank into the fixed pipe. Inside the pipe, the water is sprayed out through the nozzle to extinguish the fire. Once the fire extinguishing operation is complete, the nozzle stops spraying water. The electric push rod moves the support rod, which in turn moves the fixed pipe, nozzle, connecting rod, and water pipe away from the slot and into the steel body. At the same time, the torsion spring resets, and the baffle rotates in the opposite direction along the fixed rod as the connecting rod moves. The connecting rod enters the steel body, the slot is blocked by the baffle, and the electric push rod stops working. This prevents the nozzle from being exposed to the outside when not in use and prevents the nozzle nozzle from being blocked by a large amount of dust and impurities, thus avoiding affecting the later use of the nozzle.

[0004] However, when this steel structure is used for fire extinguishing, the nozzles can only spray water in the direction the nozzles are facing, which limits the range of water sprayed by the nozzles, affecting the fire extinguishing effect and practicality. Therefore, a fireproof steel structure for buildings is designed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a fireproof steel structure for buildings.

[0006] The technical problem to be solved by this utility model is to provide a fireproof steel structure for buildings, which solves the problem that the fire extinguishing range of existing fireproof steel structures is limited and affects the fire extinguishing effect.

[0007] This utility model provides a fireproof steel structure for buildings, including a hollow steel body, a track groove, an opening groove, a mounting plate, mounting bolt holes, a sliding rod, a baffle, and an electric telescopic rod. Mounting plates are welded to both ends of the hollow steel body, and mounting bolt holes are provided at the four corners of each mounting plate. Track grooves are fixedly installed on both the inner and outer sides of the bottom surface of the hollow steel body. Multiple opening grooves are spaced apart on the bottom surface of the hollow steel body. Sliding rods are slidably installed within the track grooves. Multiple baffles are welded between the sliding rods at intervals. An electric telescopic rod is installed between the left ends of two sliding rods and the left mounting plate. A water inlet pipe is inserted through the upper outer surface of the hollow steel body, and a solenoid valve is installed on the water inlet pipe. A horizontal pipe is inserted through the inner end of the water inlet pipe, and multiple drain pipes are inserted through the bottom of the horizontal pipe. A nozzle is rotatably mounted on the bottom of the drain pipe via a waterproof bearing. A drive assembly for simultaneously rotating multiple nozzles is installed inside the hollow steel body.

[0008] Preferably, the baffle plate is closely attached to the bottom surface of the hollow steel body, and the side length of the baffle plate is greater than the side length of the opening slot, and the distance between two adjacent opening slots is equal to the distance between two adjacent baffle plates.

[0009] Preferably, when the electric telescopic rod is extended to its maximum length, the blocking plate and the opening slot are staggered, and when the electric telescopic rod is extended to its minimum length, multiple blocking plates block multiple opening slots.

[0010] Preferably, the number of nozzles is the same as the number of opening slots, and each nozzle has an opening slot below it, with the bottom horizontal height of the nozzle equal to the bottom horizontal height of the opening slot.

[0011] Preferably, the water inlet pipe is connected to an external tap water source.

[0012] Preferably, the drive assembly includes a drive motor installed at the right end of the hollow steel body and two driven pulleys installed on each nozzle. The output end of the drive motor is equipped with a drive pulley. A transmission belt is sleeved between the drive pulley and a driven pulley on the rightmost nozzle. A transmission belt is also sleeved between the driven pulleys on two adjacent nozzles.

[0013] Preferably, a temperature sensor is fixedly installed on the inner side of the hollow steel body, and a controller is installed on one side of the temperature sensor.

[0014] Preferably, the electric telescopic rod, solenoid valve, temperature sensor, controller, and motor are all electrically connected to an external power source, and the controller is electrically connected to the electric telescopic rod, solenoid valve, temperature sensor, and motor.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] 1. This utility model, by setting open slots and baffles, allows the electric telescopic rod to extend to its minimum length when fire extinguishing is not required. At this time, multiple baffles block multiple open slots, so that the nozzle is inside the hollow steel body, preventing dust from clogging the nozzle orifice.

[0017] 2. In the event of a fire, the two electric telescopic rods extend and drive the two sliding rods to move to the right along the track groove, which in turn drives the blocking plate between the two sliding rods to move to the right. The blocking plate and the opening groove are misaligned. Then, the solenoid valve is opened, and natural water enters the horizontal pipe through the water inlet pipe and then flows from the drain pipe to the nozzle to spray out, thus achieving the effect of extinguishing the fire.

[0018] 3. This utility model is equipped with a drive component. During the fire extinguishing process, the motor drives the active pulley to rotate. The active pulley drives the rightmost nozzle to rotate through the transmission belt. The rightmost nozzle drives the nozzles to its left to rotate in sequence through the transmission belt, so that all nozzles rotate. During the water spraying process, under the action of centrifugal force of the rotating nozzle, the water sprayed by the nozzle can be flung around the nozzle, increasing the spraying range of the nozzle and ensuring the fire extinguishing effect.

[0019] 4. This utility model is equipped with a temperature sensor and a controller. When the temperature sensor detects that the temperature is too high and fire extinguishing is required, the controller controls the electric telescopic rod to extend so that the baffle plate will not block the opening slot. Then, the controller controls the solenoid valve and motor to open, and water enters the horizontal pipe 7 and the drain pipe and sprays out from the nozzle. The motor drives multiple nozzles to rotate through the transmission belt, so as to achieve the effect of automatic fire extinguishing. Attached Figure Description

Detailed Implementation

[0027] Example:

[0028] like Figures 1-4 As shown, an embodiment of this utility model provides a fireproof steel structure for buildings, including a hollow steel body 1, a track groove 101, an opening groove 102, a mounting plate 2, mounting bolt holes 201, a sliding rod 3, a baffle 4, and an electric telescopic rod 5. Mounting plates 2 are welded to both the left and right ends of the hollow steel body 1, and mounting bolt holes 201 are provided at each of the four corners of the mounting plate 2. Track grooves 101 are fixedly provided on both the inner and outer sides of the bottom surface of the hollow steel body 1. Multiple opening grooves 102 are spaced apart on the bottom surface of the hollow steel body 1. The track grooves 101 contain... A sliding rod 3 is provided, and multiple baffle plates 4 are welded between the two sliding rods 3 at intervals. An electric telescopic rod 5 is installed between the left end of the two sliding rods 3 and the left mounting plate 2. A water inlet pipe 6 is provided through the upper part of the outer surface of the hollow steel body 1. A solenoid valve 601 is installed on the water inlet pipe 6. A horizontal pipe 7 is provided through the inner end of the water inlet pipe 6. Multiple drain pipes 8 are provided through the bottom of the horizontal pipe 7. A nozzle 9 is rotatably installed at the bottom of the drain pipe 8 through a waterproof bearing. A drive assembly for driving multiple nozzles 9 to rotate simultaneously is installed inside the hollow steel body 1.

[0029] In this embodiment, the baffle plate 4 is in close contact with the bottom surface of the hollow steel body 1, and the side length of the baffle plate 4 is greater than the side length of the opening slot 102. The distance between two adjacent opening slots 102 is equal to the distance between two adjacent baffle plates 4.

[0030] In this embodiment, when the electric telescopic rod 5 is extended to its maximum length, the baffle plate 4 and the opening slot 102 are staggered. When the electric telescopic rod 5 is extended to its minimum length, multiple baffle plates 4 block multiple opening slots 102, thereby achieving the effect of protecting the nozzle 9 inside the hollow steel structure.

[0031] In this embodiment, the number of nozzles 9 is the same as the number of opening slots 102, and each nozzle 9 corresponds to an opening slot 102 below it. The bottom horizontal height of the nozzle 9 is equal to the bottom horizontal height of the opening slot 102, so that the nozzle 9 will not affect the blocking of the opening slot 102 by the baffle plate 4.

[0032] In this embodiment, the water inlet pipe 6 is connected to an external tap water source to facilitate the entry of water into the water inlet pipe 6.

[0033] With the opening slot 102 and the baffle plate 4, when fire extinguishing is not required, the electric telescopic rod 5 extends to its minimum length. At this time, multiple baffle plates 4 block multiple opening slots 102, so that the nozzle 9 is inside the hollow steel body 1, preventing dust from clogging the nozzle 9's nozzle with dust and other impurities.

[0034] In the event of a fire, the two electric telescopic rods 5 extend and drive the two sliding rods 3 to move to the right along the track groove 101, which in turn drives the baffle plate 4 between the two sliding rods 3 to move to the right. The baffle plate 4 is offset from the opening groove 102. Then, the solenoid valve 601 is opened, and natural water enters the horizontal pipe 7 through the water inlet pipe 6, and then flows from the drain pipe 8 to the nozzle 9 to spray out, thus achieving the effect of extinguishing the fire.

[0035] In this embodiment, the drive assembly includes a drive motor 12 installed at the right end of the hollow steel body 1 and two driven pulleys 901 installed on each nozzle 9. The output end of the drive motor 12 is equipped with a drive pulley 1201. A transmission belt 1202 is sleeved between the drive pulley 1201 and a driven pulley 901 on the rightmost nozzle 9. A transmission belt 1202 is also sleeved between the driven pulleys 901 on two adjacent nozzles 9.

[0036] By incorporating a drive assembly, during fire extinguishing, the motor 12 drives the drive pulley 1201 to rotate. The drive pulley 1201, through the transmission belt 1202, drives the rightmost nozzle 9 to rotate. The rightmost nozzle 9, through the transmission belt 1202, sequentially drives the nozzles 9 to its left to rotate, ensuring that all nozzles 9 rotate. During the water spraying process, the centrifugal force of the rotating nozzles 9 causes the water sprayed from the nozzles 9 to be flung around the nozzles 9, increasing the spraying range of the nozzles 9 and ensuring the fire extinguishing effect.

[0037] In this embodiment, a temperature sensor 10 is fixedly installed on the inner side of the hollow steel body 1, and a controller 11 is installed on one side of the temperature sensor 10.

[0038] In this embodiment, the electric telescopic rod 5, solenoid valve 601, temperature sensor 10, controller 11 and motor 12 are all electrically connected to an external power source, and the controller 11 is electrically connected to the electric telescopic rod 5, solenoid valve 601, temperature sensor 10 and motor 12.

[0039] With a temperature sensor 10 and a controller 11, when the temperature sensor 10 senses that the temperature is too high and fire needs to be extinguished, the controller 11 controls the electric telescopic rod 5 to extend so that the baffle plate 4 will not block the opening slot 102. Then, the controller controls the solenoid valve 601 and the motor 12 to open, and water enters the horizontal pipe 7 and the drain pipe 8 and sprays out from the nozzle 9. The motor 12 drives multiple nozzles 9 to rotate through the transmission belt 1202, so as to achieve the effect of automatic fire extinguishing.

[0040] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
