Description

Technical Field

[0001] The present invention relates to the technical field of curtain walls, and particularly to a fireproof, heat-insulating and energy-saving curtain wall for buildings. Background Art

[0002] A curtain wall is an exterior wall enclosure of a building, which does not bear weight and is hung like a curtain, so it is also called a "curtain wall". It is a lightweight wall with a decorative effect commonly used in modern large-scale and high-rise buildings. Curtain walls are widely used in various high-rise buildings, commercial centers, airports, railway stations and other large public buildings.

[0003] An existing patent, a fireproof, heat-insulating and energy-saving building curtain wall and its using method (CN117344896A), includes a vertical connecting plate. An L-shaped plate is connected to the side wall of the vertical connecting plate by bolts, and a horizontal connecting plate is sleeved on the outer wall of the L-shaped plate. And a glass curtain wall plate is inserted into one side of the vertical connecting plate. Two groups of the vertical connecting plate and the horizontal connecting plate are symmetrically arranged about the vertical axis and the horizontal axis of the glass curtain wall plate respectively. A crushing mechanism is arranged on the bottom wall of the horizontal connecting plate.

[0004] The technical solution proposed in this application can collect the fragmented glass after a fire, avoiding the problem that the flying glass is easy to hurt people. However, after installing the curtain wall, the curtain wall blocks the ventilation between the building and the outside. Therefore, a high-power air circulation device is required to circulate the air. Especially for some curtain wall plates made of opaque materials, more lighting facilities need to be added after installation. The use of the air circulation device and the lighting device causes waste of energy. For this reason, a new fireproof, heat-insulating and energy-saving curtain wall is needed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a fireproof, heat-insulating and energy-saving curtain wall for buildings, which solves the problems raised in the background art.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A fireproof, heat-insulating and energy-saving curtain wall for buildings, comprising an inner connection mechanism and a curtain wall panel. The inner connection mechanism is fixedly installed on the inner side of the curtain wall panel. The curtain wall panel includes a plurality of heat-insulating layers arranged at intervals. The intervals between the plurality of heat-insulating layers in one direction of the curtain wall panel are less than the thickness of the heat-insulating layer, and the intervals between the plurality of heat-insulating layers in the other direction of the curtain wall panel are equal to the height of the heat-insulating layer. An air supply duct is embedded in the middle of the heat-insulating layer. The air supply ducts between different heat-insulating layers are fixedly connected by connecting pieces. The connecting pieces are located between adjacent heat-insulating layers. A light guide fiber parallel to the air supply duct is embedded in the middle of the heat-insulating layer. The outer surfaces of the heat-insulating layer, the air supply duct and the light guide fiber are all covered with a wrapping layer. The two end faces of the wrapping layer are flush with the two end faces of the air supply duct. A semi-circular protrusion is provided above the wrapping layer where the air supply duct is installed. The inner connection mechanism includes an I-shaped steel frame. The curtain wall panel and the I-shaped steel frame are fixedly connected by bolts. Connecting threaded holes are provided at the rear end of the I-shaped steel frame, which are arranged in a dislocation manner with the bolts connecting the curtain wall panel.

[0007] A square frame is inserted between the two I-shaped steel frames. The square frame and the I-shaped steel frame are fixedly connected by screws. A sealing gasket covering the air supply duct is rotatably connected inside the square frame. A shielding piece covering the light guide fiber is rotatably connected inside the square frame.

[0008] Two supporting plates are fixedly installed at both ends inside the square frame. One end of the shielding piece is rotatably connected to the supporting plate and the other end extends outside the supporting plate. A sprocket is fixedly installed on the central axis of the shielding piece on this side. All the sprockets are alternately wrapped on the outer surfaces of the sprockets through a chain for driving connection. A torsion spring sleeve is fixedly installed on the central axis of the sealing gasket at this end. A driving gear is fixedly installed at the other end of the central axis of the sealing gasket at this end. A driving rack plate is engaged below the driving gear. All the driving rack plates are fixedly connected by a connecting rod. A sliding block is fixedly installed at the rear end of the outermost driving rack plate. A lead screw is threadedly connected to the middle of the sliding block. A worm gear is fixedly installed at the end of the lead screw away from the sliding block. A worm is engaged above the worm gear. The worm is rotatably connected to the supporting plate. A power gear is fixedly installed at the end of the worm away from the supporting plate. A power rack plate is engaged below the power gear. The power rack plate is slidably connected to the square frame.

[0009] Preferably, a protrusion is fixedly installed on the inner bottom wall of the square frame. The power rack plate and the driving rack plate are slidably connected to the protrusion. A tension pulley is rotatably connected to the inner bottom wall of the square frame. The tension pulley is sleeved on the inner ring of the chain.

[0010] Preferably, notches are provided on both sides at one end of the I-shaped steel frame. The tension pulley and the power rack plate protrude from the notches.

[0011] Preferably, the air supply duct is inclined, with the lowest side near the semi-circular protrusion and the highest side away from the semi-circular protrusion.

[0012] Preferably, the air supply duct is a light guide pipe. A light collecting lens is arranged on one side of the semi-circular protrusion. A through hole communicating with the air supply duct is formed in the middle of the light collecting lens.

[0013] The present invention has the following beneficial effects:

[0014] 1. For the fireproof, heat-insulating and energy-saving curtain wall for buildings, the connecting piece is arranged between the heat-insulating layers, and the air supply duct passes through the heat-insulating layer and the connecting piece. The optical fiber is inserted into the middle of the heat-insulating layer, and this part is placed into the guiding mold. The limiting cement is poured into the mold. After molding, both sides are polished so that the end faces of the wrapping layer are flush with the end faces of the air supply duct, thereby forming a curtain wall board that can both keep warm and ventilate and transmit light.

[0015] 2. For the fireproof, heat-insulating and energy-saving curtain wall for buildings, the curtain wall board includes a plurality of heat-insulating layers arranged at intervals. The heat-insulating layer uses a polyurethane heat-insulating board, which can keep warm while being fireproof. The intervals of the plurality of heat-insulating layers in one direction of the curtain wall board are less than the thickness of the heat-insulating layer, and the intervals of the plurality of heat-insulating layers in the other direction of the curtain wall board are equal to the height of the heat-insulating layer. Through such a setting, the heat-insulating layers can be continuously arranged but not in contact with each other, thereby avoiding the ignition of the upper heat-insulating layer after combustion.

[0016] 3. For the fireproof, heat-insulating and energy-saving curtain wall for buildings, the air supply duct is a light guide pipe. A light collecting lens is arranged on one side of the semi-circular protrusion. The light collecting lens can concentrate natural light and irradiate the light guide pipe. A through hole communicating with the air supply duct is formed in the middle of the light collecting lens, and the through hole can be used for air intake, thereby achieving the effect of transmitting light while intake air.

[0017] 4. For the fireproof, heat-insulating and energy-saving curtain wall for buildings, a sealing gasket covering the air supply duct is rotatably connected inside the square frame. A torsion spring sleeve is fixedly installed at the central axis of the sealing gasket. By setting the torsion spring sleeve, the sealing gasket can be restricted, so that the sealing gasket always keeps close to the curtain wall board without external force, thereby avoiding air leakage.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] The embodiment of the present invention provides a fireproof, heat-insulating and energy-saving curtain wall for buildings:

[0030] Such as Figures 1-9As shown in the figure, it includes an internal connection mechanism 1 and a curtain wall panel 2. The internal connection mechanism 1 is fixedly installed on the inner side of the curtain wall panel 2 and is used to connect with the curtain wall frame. The curtain wall panel 2 includes a plurality of heat insulation layers 201 arranged at intervals. The heat insulation layer 201 uses a polyurethane insulation board, which can provide heat insulation while being fireproof. The intervals of the plurality of heat insulation layers 201 in one direction of the curtain wall panel 2 are less than the thickness of the heat insulation layer 201, and the intervals of the plurality of heat insulation layers 201 in the other direction of the curtain wall panel 2 are equal to the height of the heat insulation layer 201. Through such a setting, the heat insulation layers 201 can be continuously arranged but not in contact with each other, so as to avoid continuous combustion during a fire. An air supply duct 202 is embedded in the middle of the heat insulation layer 201. The air supply ducts 202 between different heat insulation layers 201 are fixedly connected through connection pieces 206. The connection pieces 206 are located between adjacent heat insulation layers 201. The air supply duct 202 can play a role in ventilation and, in cooperation with the connection piece 206, can play a role in frame support, thereby improving the strength of the curtain wall panel 2. A light guide fiber 203 parallel to the air supply duct 202 is embedded in the middle of the heat insulation layer 201. The material of the light guide fiber 203 is glass. The outer surfaces of the heat insulation layer 201, the air supply duct 202, and the light guide fiber 203 are all covered with a wrapping layer 204. The material of the wrapping layer 204 is fiber cement. The connection piece 206 is arranged between the heat insulation layers 201, and the air supply duct 202 passes through the heat insulation layer 201 and the connection piece 206. The light guide fiber 203 is inserted into the middle of the heat insulation layer 201, and this part is placed in a guide mold. Limiting cement is poured into the mold. After molding, both sides are polished so that the end faces of the wrapping layer 204 are flush with the end faces of the air supply duct 202.

[0031] A semi-circular protrusion 205 is provided above the wrapping layer 204 where the air supply duct 202 is installed. The semi-circular protrusion serves as a drip edge to prevent water from entering the air supply duct 202. At the same time, the semi-circular protrusion 116 is formed by filling the wrapping layer 204 in the mold. The internal connection mechanism 1 includes an I-shaped steel frame 101. The curtain wall panel 2 and the I-shaped steel frame 101 are fixedly connected by bolts. A connection threaded hole 102 is opened at the rear end of the I-shaped steel frame 101, which is arranged in a dislocation manner with the connection bolts of the curtain wall panel 2. The I-shaped steel frame 101 is connected to the curtain wall connection frame by bolts. By setting the dislocation, space can be provided for fine adjustment of the bolts, so that fine adjustment can be carried out.

[0032] A square frame 103 is inserted between two I-shaped steel frames 101. The square frame 103 and the I-shaped steel frame 101 are fixedly connected by screws. A sealing gasket 104 covering the air supply duct 202 is rotatably connected inside the square frame 103, and a shielding piece 105 covering the light guide fiber 203 is rotatably connected inside the square frame 103. By adjusting the rotation angle of the sealing gasket 104, the amount of air supply can be adjusted. By setting the shielding piece 105, the amount of light passing through can be changed. Through such a setting, the amount of incoming light and the amount of ventilation can be adjusted according to environmental requirements.

[0033] At both inner ends of the square frame 103, support plates 106 are fixedly installed. One end of the shielding piece 105 is rotatably connected to the support plate 106, and the other end extends to the outside of the support plate 106. A sprocket 107 is fixedly installed at the center axis of this side of the shielding piece 105. All the sprockets 107 are alternately wrapped on the outer surface of the sprockets 107 through a chain 121 for driving connection. Positioning beads are fixedly connected to the surface of the chain 121, and grooves adapted to the positioning beads are provided on the surface of the sprocket 107. By pulling the chain 121, all the sprockets 107 can be driven to rotate, so that the inclination angle of the shielding piece 105 can be adjusted.

[0034] At the center axis of this end of the gasket 104, a torsion spring sleeve 108 is fixedly installed. By providing the torsion spring sleeve 108, the gasket 104 can be restricted, so that the gasket 104 always remains in close contact with the curtain wall panel 2 without external force, thereby avoiding air leakage. At the other end of the center axis of this end of the gasket 104, a driving gear 118 is fixedly installed. A driving rack plate 109 is engaged below the driving gear 118. The rotation of the gasket 104 is controlled through gear transmission. All the driving rack plates 109 are fixedly connected through a connecting rod 119. Through such a setting, it can be ensured that all the gaskets 104 can move simultaneously. A sliding block 110 is fixedly installed at the rear end of the outermost driving rack plate 109. A lead screw shaft 111 is threadedly connected to the middle of the sliding block 110. One end of the lead screw shaft 111 away from the sliding block 110 is fixedly installed with a worm gear 112. A worm 113 is engaged above the worm gear 112. Due to the provision of the torsion spring sleeve 108, it is necessary to achieve self-locking through worm and worm gear transmission to fix the adjusted position. The worm 113 is rotatably connected to the support plate 106. One end of the worm 113 away from the support plate 106 is fixedly installed with a power gear 114. A power rack plate 115 is engaged below the power gear 114. The power rack plate 115 is slidably connected to the square frame 103. Through such a setting, it is convenient to drive the gasket 104 to rotate.

[0035] A protrusion 116 is fixedly installed on the inner bottom wall of the square frame 103. The power rack plate 115 and the driving rack plate 109 are slidably connected to the protrusion. Through such a setting, the power rack plate 115 and the driving rack plate 109 can be limited, so that they can only slide in one direction. A tension wheel 117 is rotatably connected to the inner bottom wall of the square frame 103. The tension wheel 117 is sleeved on the inner ring of the chain 121. The tension wheel 117 can keep the chain 121 in a tensioned state so as to remain in contact with the sprocket 107 for facilitating the adjustment of the shielding piece 105.

[0036] On both sides of one end of the I-shaped steel frame 101, there are gaps 120, and the tension wheels 117 and the power rack plates 115 leak out from the gaps 120. Through such a setting, an operating space can be reserved for pulling the chain 121 and the power rack plate 115.

[0037] The air supply pipe 202 is inclined, with the side close to the semi-circular protrusion 205 being the lowest and the side far from the semi-circular protrusion 205 being the highest. Through such a setting, water leakage into the inner side through the air supply pipe 202 can be avoided.

[0038] The air supply pipe 202 is a light guide pipe, and the material of the air supply pipe 202 is a material with a high total reflection filter. On one side of the air supply pipe 202 located at the semi-circular protrusion 205, there is a light collecting lens 207. The light collecting lens 207 can concentrate natural light and irradiate the light guide pipe. A through hole 208 communicating with the air supply pipe 202 is opened in the middle of the light collecting lens 207. The through hole 208 can be used for air intake. At the same time, a diffuser can be set at one end of the light guide pipe to increase the irradiation effect, or a filtering device can be inlaid at the through hole 208 to prevent dust from entering the interior of the light guide pipe.

[0039] During production, the connecting piece 206 is arranged between the heat insulation layers 201, and the air supply pipe 202 passes through the heat insulation layers 201 and the connecting piece 206. The optical fiber 203 is inserted into the middle of the heat insulation layer 201, and this part is placed in a guiding mold. Limiting cement is poured into the mold. After molding, both sides are polished so that the end faces of the wrapping layer 204 are flush with the end faces of the air supply pipe 202, thereby forming a curtain wall board 2 that can both keep warm and allow air ventilation and light transmission.

[0040] During use, when it is necessary to change the incident light, pulling the chain 121 to move can drive the sprocket 107 to rotate, thereby being able to change the inclination angle of the shielding piece 105. The larger the inclination angle of the shielding piece 105, the more light transmission. By sliding the power rack plate 115 to move, the power gear 114 can be driven to rotate, and then the sealing gasket 104 can be driven to rotate through worm and gear transmission and gear and rack plate transmission. The larger the rotation angle of the sealing gasket 104, the more air intake.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
