Description

Technical Field

[0001] The utility model relates to the field of fireproof coatings for steel structures, in particular to a template pouring device for the construction of thick fireproof coatings. Background Art

[0002] Thick steel structure fire retardant coating refers to a coating with a thickness greater than 7mm and less than 45mm, a granular surface, low density, low thermal conductivity, and a fire resistance limit of more than 2h. Since thick fire retardant coatings are mostly composed of inorganic materials, their fire retardant performance is stable and the long-term use effect is good, but the particles of the coating components are large and the coating appearance is uneven, affecting the overall beauty of the building. Therefore, most of them are used in structural concealed projects. This type of fire retardant coating uses the granular surface of the material, low density, low thermal conductivity or the heat absorption of the material in the coating to delay the temperature rise of the steel and protect the steel in a fire.

[0003] The current template pouring device for thick fire retardant coating construction, as described in the patent with announcement number CN104775596B, includes the following steps: (1) using the template to cover the surface of the steel structure, reserving a pouring space according to the thickness of the fire retardant coating, and reserving a pouring port at the closed part of the template; (2) pouring the fire retardant coating into the pouring port, and pouring the fire retardant coating along the pouring space to fill it densely; (3) closing the pouring port. A thick fire retardant coating construction device is also disclosed, including a template covering the surface of the steel structure, the template including a metal mesh and an inorganic cloth, the metal mesh is pressed on the surface of the inorganic cloth, the inorganic cloth is covered on the surface of the steel structure, and a pouring space corresponding to the thickness of the fire retardant coating is formed, and a closable pouring port is provided at the closed part of the metal mesh and the inorganic cloth.

[0004] With respect to the above-mentioned related technologies, the inventors believe that since both ends of each support frame are fixed vertically to the steel structure surface and the wire mesh by welding, the entire formwork cannot be disassembled and reused, which in turn causes a high construction cost for pouring thick fire retardant coatings.

DETAILED DESCRIPTION

[0025] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0026] See also Figure 1-4 A template pouring device for thick fire retardant coating construction includes a support mechanism 1, which includes a fixed seat 101, a movable seat 102 is provided on one side of the fixed seat 101, and the tops of the fixed seat 101 and the movable seat 102 are symmetrically fixedly connected with side plates 107, and two groups of side plates 107 on the same side are rotatably connected with bidirectional screws 104, and the side plates 107 are arranged to support the bidirectional screws 104. The outer sides of the two groups of bidirectional screws 104 are symmetrically threaded with support plates 103, and the bidirectional screws 104 can drive the two groups of support plates 103 on the same side to move relative to or away from each other when rotating, so as to adjust the spacing between the two groups of support plates 103 on the same side. A guide rod 105 is slidably penetrated inside the two groups of support plates 103 on the same side, and the guide rods 105 on both sides are fixedly connected to the side plates 107 on both sides, respectively, and the guide rods 105 are arranged to guide the movement of the support plates 103.

[0027] The pouring mechanism 2 includes a lower template 202 disposed between the fixed seat 101 and the movable seat 102. The top of the lower template 202 abuts against the matching upper template 201. The space formed by the upper template 201 and the lower template 202 is used to accommodate the steel. The lower template 202 and the upper template 201 are both fixedly connected with connecting plates 207 on both sides, so that the support plate 103 can provide support for the connecting plate 207, thereby achieving the function of supporting the lower template 202. The bottom of the upper connecting plate 207 is fixedly connected with a second sealing gasket 208, and the second sealing gasket 208 abuts against the lower connecting plate 207. The second sealing gasket 208 can seal the gap between the two groups of connecting plates 207 to reduce the probability of leakage of the fire retardant coating. A plurality of positioning rods 209 are evenly and fixedly connected to the bottom of the upper connecting plate 207 , and each group of positioning rods 209 slides through the lower connecting plate 207 . The arrangement of the positioning rods 209 can play a guiding and positioning role during the closing process of the upper mold plate 201 and the lower mold plate 202 .

[0028] The outer side of each group of positioning rods 209 is sleeved with a traction spring 211, one end of each group of traction springs 211 is fixedly connected to the lower connecting plate 207, and the bottom of each group of traction springs 211 is fixedly connected with a traction block 210, and each group of traction blocks 210 abuts against each group of positioning rods 209. Specifically, the traction spring 211 is in a stretched state, so that after the downward pressure on the movable seat 102 stops, the traction spring 211 recovers its deformation, thereby pulling the traction block 210, the positioning rod 209 and the upper template 201 to move upward, thereby realizing automatic mold opening. The interior of each group of support plates 103 is symmetrically connected with rollers 106, and the rollers 106 on both sides are in contact with the connecting plates 207 on both sides respectively. The setting of the rollers 106 can reduce the wear between the connecting plate 207 and the support plate 103.

[0029] The inner bottom wall of the lower template 202 is evenly fixedly connected with a plurality of support columns 212. The setting of the support columns 212 can provide support for the steel. After demoulding, the holes formed by the support columns 212 can be filled with fire retardant coating. The top of the upper template 201 is evenly fixedly connected with a plurality of interconnected evaporation tubes 203. The setting of the evaporation tubes 203 facilitates the evaporation of water in the fire retardant coating, thereby facilitating the solidification of the fire retardant coating. The other side of the top of the upper template 201 is fixedly connected with a connected perfusion pipe 206. One side of the fixed seat 101 is fixedly connected with a pump 204. The output end of the pump 204 is fixedly connected with a connected hose 205. The end of the hose 205 away from the pump 204 is threadedly connected to the perfusion pipe 206. The setting of the pump 204 is used to extract the fire retardant coating into the inside of the hose 205 when starting the work, and then discharge it into the inside of the lower template 202 and the upper template 201 through the perfusion pipe 206.

[0030] The adjustment mechanism 3 includes a sliding rod 302 symmetrically fixedly connected to the fixed seat 101 near the moving seat 102. Both sets of sliding rods 302 are slidably connected to the moving seat 102, and the sliding rod 302 can guide the movement of the moving seat 102. The ends of the two sets of sliding rods 302 away from the fixed seat 101 are fixedly connected with a fixed plate 303, and an adjusting screw 304 is rotatably connected between the fixed seat 101 and the fixed plate 303. The adjusting screw 304 is threadedly connected to the moving seat 102. A stepper motor 301 is fixedly connected to one side of the fixed seat 101, and the output end of the stepper motor 301 is fixedly connected to one end of the adjusting screw 304. The stepper motor 301 can drive the adjusting screw 304 to rotate when starting the work, and the adjusting screw 304 can drive the moving seat 102 to move when rotating to adapt to steels of different lengths. The first sealing gasket 108 is fixedly connected to the opposite sides of the fixed seat 101 and the movable seat 102. The first sealing gasket 108 abuts against the upper template 201 and the lower template 202. The first sealing gasket 108 can seal the gap between the movable seat 102 and the fixed seat 101 and the upper template 201 and the lower template 202 to reduce the probability of leakage of the fire retardant coating.

[0031] The tops of the fixed seat 101 and the movable seat 102 are both rotatably connected to the traction frame 305, and a pressure rod 307 is fixedly connected to one side of the traction frame 305. The opposite sides of the fixed seat 101 and the movable seat 102 are both rotatably connected to the hydraulic rod 306. The output ends of the two groups of hydraulic rods 306 are respectively rotatably connected to the two groups of traction frames 305. When the hydraulic rod 306 is started, the traction frame 305 and the pressure rod 307 can be pulled to rotate, so that the upper template 201 can be pressed to achieve the mold closing operation. The outer sides of the two groups of pressure rods 307 are both rotatably connected to the rollers 308, and the two groups of rollers 308 are both in contact with the upper template 201. The setting of the rollers 308 can separate the pressure rod 307 from the upper template 201 to reduce the probability of wear between the pressure rod 307 and the upper template 201.

[0032] When in use, the matching fixed seat 101 and movable seat 102 are selected according to the specifications of the steel to be constructed, and then the stepper motor 301 is started, so that the stepper motor 301 can drive the adjusting screw 304 to rotate when starting work, and the adjusting screw 304 can drive the sliding rod 302 under the movable seat 102 to slide when rotating, until the distance between the movable seat 102 and the fixed seat 101 is adjusted to be longer than the length of the steel, and then the bidirectional screws 104 on both sides are rotated, so that the bidirectional screws 104 can drive the support plates 103 on both sides to move relative to or relative to each other when rotating. The lower template 202 is then hoisted to the top of the support plate 103 so that each group of rollers 106 can support the connecting plates 207 on both sides of the lower template 202. The steel is then hoisted to the inside of the lower template 202 so that each group of support columns 212 can support the steel. The upper template 201 is then hoisted so that each group of positioning rods 209 penetrates the lower connecting plate 207. The hydraulic rods 3 on both sides can then be activated. 06, so that the hydraulic rod 306 extends to drive the traction frame 305 and the pressure rod 307 on both sides to rotate, so that the roller 308 presses the upper template 201 downward until the second sealing gasket 208 is tightly against the lower connecting plate 207, thereby sealing the gap between the upper template 201 and the lower template 202, and at the same time, the positioning rod 209 pushes the upper template 201 to move downward, and the upper template 201 is pushed and stretched, and then the stepping motor 301 can be started again, thereby driving the moving seat 102 to move to one side of the fixed seat 101, until the second sealing gasket 208 and the lower connecting plate 207 on both sides are tightly pressed. A sealing gasket 108 is pressed against both sides of the upper template 201 and the lower template 202, and then the hose 205 and the perfusion pipe 206 can be screwed and fixed, and then the input end of the pump 204 is connected to the fire retardant coating, and the pump 204 is started, so that when the pump 204 starts working, the fire retardant coating can be discharged to the inside of the upper template 201 and the lower template 202 through the hose 205 and the perfusion pipe 206, thereby wrapping the outside of the steel, so as to realize the construction of thick fire retardant coating on the steel, and after the coating solidifies, a fire retardant coating can be formed on the outer wall of the steel.
