Description

Technical Field

[0001] The invention relates to the technical field, and in particular to an anti-condensation steel structure roof. Background Art

[0002] Steel structure workshops are widely used in newly built or expanded workshops due to their advantages such as factory production, short construction period, quick results, low cost, large span and beautiful appearance. However, some workshops have partial or large-area condensation on the roofs in winter when they are built and put into production or after a period of use. The insulation effect of the workshops is significantly reduced, and even large-area wetting or dripping of the ceiling occurs. The formed water droplets drip irregularly in the workshop, affecting the product quality of precision processing enterprises. The production has to be interrupted, causing huge economic losses. Therefore, it is of great significance to formulate anti-condensation measures for steel structure workshop roofs.

[0003] Due to the needs of electronic and precision product production processes, the temperature and humidity in the workshop must be maintained at a relatively high level even in winter. The large temperature and humidity difference between indoors and outdoors in winter puts forward more stringent requirements on the insulation of the enclosing structure, and is also the root cause of condensation.

[0004] In steel structure buildings, the roofs are mostly made of a combination of metal roof panels and glass fiber insulation wool. The most commonly used insulation materials are glass fiber insulation wool, polyurethane sandwich panels, polystyrene sandwich panels, etc. The main features of these materials are light weight, low thermal conductivity, and good insulation performance; glass fiber insulation wool is the most widely used roof and wall insulation material, with a general density of 12 to 16 kg / m, and the bottom is covered with kraft paper, aluminum foil, polyester materials and other waterproof and air-proof veneers to form an insulation and vapor insulation structure. The reason for the large-scale uniform condensation on the roof is mostly due to the insufficient thickness of the roof insulation layer, and the density and fineness do not meet the regulations; glass wool weathers and becomes solid after a period of use, causing the roof insulation performance to decline, and condensation occurs when the temperature and humidity difference between indoor and outdoor is large in winter.

[0005] In order to prevent the insulation layer at the purlin from deforming, several small purlins perpendicular to the purlins are generally provided in the insulation layer to support the insulation layer. However, this increases the process and materials, the cost is excessively increased, and the insulation effect of the insulation cotton at the small purlins is still lower than that at other parts. Summary of the invention

[0006] The present invention aims at solving the deficiencies of the prior art and provides a condensation-proof steel structure roof.

[0007] The present invention solves the above technical problems through the following technical means:

[0009] The roof comprises: an upper plate layer, a lower plate layer and a heat-insulating layer; the upper plate layer is formed by splicing a plurality of upper plates, and the adjacent upper plates in a direction parallel to the purlin overlap at the raised portion; the lower plate layer is formed by splicing a plurality of lower plates, and the adjacent lower plates in a direction parallel to the purlin overlap at the raised portion; the raised portion is fixed to the purlin by setting a fixing device;

[0010] The fixing device includes: a first fixing mechanism for fixing adjacent upper plates in a direction parallel to the purlin, a second fixing mechanism for supporting the insulation layer and fixing the upper plate layer and the lower plate layer, and a third fixing mechanism for fixing the lower plate layer and the purlin; the first fixing mechanism, the second fixing mechanism and the third fixing mechanism are fixedly connected.

[0012] As an improvement of the above technical solution, the first fixing mechanism includes an outer frame for fixing the arc-shaped plates on adjacent upper plates and a connecting piece that fixes the outer frame to the second fixing mechanism; the outer frame includes: a top plate, a side plate and an L-shaped bottom plate; the top plate is provided with a connecting groove for accommodating the connecting piece, the side plates are provided with two, respectively arranged on both sides of the top plate along a direction parallel to the purlin, for clamping the arc-shaped plates, the bottom plates are provided with two, respectively arranged between the side plates and the vertical plates, one side is connected to the side plate, and the other side is used to clamp the vertical plate.

[0013] As an improvement of the above technical solution, the connection groove and the top plate are configured to be detachably connected, the connecting piece is configured to be a heat-insulating screw, and a sealing cover for sealing the connection groove is provided at one end of the connection groove away from the connecting piece.

[0014] As an improvement of the above technical solution, the second fixing mechanism is configured as an I-shaped piece, one end of the I-shaped piece is connected to the connecting piece, and the other end is connected to the third fixing mechanism; the third fixing mechanism is configured as a C-shaped piece, one end of the C-shaped piece is connected to the I-shaped piece, and the other end is connected to the purlin.

[0015] As an improvement of the above technical solution, a vapor barrier layer is arranged between the insulation layer and the lower plate layer and between the insulation layer and the upper plate layer, and the vapor barrier layer includes an aluminum foil layer and a polyethylene woven cloth layer; the polyethylene woven cloth layer is arranged on the side close to the insulation layer.

[0016] As an improvement of the above technical solution, the thermal insulation layer is provided with at least two layers of thermal insulation cotton, and the two layers of thermal insulation cotton are overlapped with staggered seams.

[0017] As an improvement of the above technical solution, the spacing between adjacent purlins does not exceed 1.5 meters.

[0018] The beneficial effects of the present invention are as follows: the adjacent upper plates are fixed by the first fixing mechanism, the upper plate layer and the lower plate layer are fixed by the second fixing mechanism, and the lower plate layer and the purlin are fixed by the third fixing mechanism, thereby realizing the segmented fixed connection between the upper roof surface layer, the roof body and the purlin, thereby reducing the heat conduction efficiency of the fixing mechanism, and avoiding the disadvantage that condensation is easy to form at the fixing mechanism when the outside is too cold;

[0027] Example

[0028] like Figure 1 , Figure 3 As shown, the anti-condensation steel structure roof described in this embodiment includes a plurality of parallel purlins 10 and a roof arranged on the purlins 10, and the roof is provided with a protrusion 30 perpendicular to the purlins 10;

[0029] The roof comprises: an upper plate layer 21, a lower plate layer 22 and an insulation layer 23; the upper plate layer 21 is formed by splicing a plurality of upper plates 211, and the adjacent upper plates 211 in a direction parallel to the purlin 10 overlap at the raised portion 30; the lower plate layer 22 is formed by splicing a plurality of lower plates 221, and the adjacent lower plates 221 in a direction parallel to the purlin 10 overlap at the raised portion 30; the raised portion 30 is fixed to the purlin 10 by setting a fixing device;

[0030] The fixing device includes: a first fixing mechanism 40 for fixing the adjacent upper plate 211 in a direction parallel to the purlin 10, a second fixing mechanism 50 for supporting the insulation layer 23 and fixing the upper plate layer 21 and the lower plate layer 22, and a third fixing mechanism 60 for fixing the lower plate layer 22 and the purlin 10; the first fixing mechanism 40, the second fixing mechanism 50 and the third fixing mechanism 60 are fixedly connected.

[0031] The adjacent upper plates 211 are fixed by the first fixing mechanism 40, the upper plate layer 21 and the lower plate layer 22 are fixed by the second fixing mechanism 50, and the lower plate layer 22 and the purlin 10 are fixed by the third fixing mechanism 60, so as to realize the segmented fixed connection between the upper roof surface layer, the roof body and the purlin 10, thereby reducing the heat conduction efficiency of the fixing mechanism and avoiding the disadvantage that condensation is easy to form at the fixing mechanism when the outside is too cold;

[0032] The places where the steel structure roof needs to be fixed tightly are the roof surface and the connection between the roof and the purlin; the segmented fixing structure can fix the first fixing mechanism 40 and the third fixing mechanism 60 tightly, and fix the upper plate layer 21 and the lower plate layer 22 to the purlin 10 separately, so as to avoid compressing the insulation layer 23 between the upper plate layer 21 and the lower plate layer 22, and avoid the insulation layer 23 at the purlin 10 from becoming thinner, thereby reducing the insulation effect there, causing condensation.

[0033] like Figure 2 , Figure 4As shown, the upper plate 211 includes a flat plate 212, a vertical plate 213 and a curved plate 214; the vertical plate 213 is arranged on two side edges of the flat plate 212 perpendicular to the purlin 10, and the curved plate 214 is arranged on the side of the vertical plate 213 away from the flat plate 213, and one of the curved plates 214 between adjacent upper plates 211 is sleeved on the outside of the other curved plate 214.

[0034] The adjacent upper plates 211 are connected by sleeve-arranging the arc plates 214 on the adjacent upper plates 211. This installation method without the need for punching holes can better maintain the integrity of the roof and maintain the waterproof and heat-insulating properties.

[0035] like Figure 1 , Figure 2 As shown, the first fixing mechanism 40 includes an outer frame 41 for fixing the arc-shaped plate 214 on the adjacent upper plate 211 and a connecting member 42 for fixing the outer frame 41 to the second fixing mechanism 50; the outer frame 41 includes: a top plate 43, a side plate 44 and an L-shaped bottom plate 45; the top plate 43 is provided with a connecting groove 46 for accommodating the connecting member 42, the side plates 44 are provided with two, which are respectively arranged on both sides of the top plate 43 along the direction parallel to the purlin 10, for clamping the arc-shaped plate 214, and the bottom plates 45 are provided with two, which are respectively arranged between the side plates 44 and the vertical plates 213, one side is connected to the side plates 44, and the other side is used to clamp the vertical plates 213.

[0036] The connection groove 46 and the top plate 43 are configured to be detachably connected, the connection piece 42 is configured as a heat-insulating screw, and a sealing cover 47 for sealing the connection groove 46 is provided at one end of the connection groove 46 away from the connection piece 42 .

[0037] The flat plate 212, the vertical plate 213 and the curved plate 214 on the upper plate 211 are further fixed by the outer frame 41; the curved plates 214 on adjacent upper plates 211 are fixed by the connecting piece 42 to prevent relative sliding; by setting the connecting piece 42 in the connecting groove 46 and driving the thermal insulation and waterproof material into the connecting groove 46 after installation, the thermal insulation and waterproof effect is achieved; the connecting groove 46 and the top plate 43 are set to be detachably connected so that during the installation process, the inwardly protruding connecting groove 46 can be removed to avoid affecting the installation of the upper plate layer 21.

[0038] like Figure 1 As shown, the second fixing mechanism 50 is configured as an I-shaped piece, one end of which is connected to the connecting piece 42, and the other end is connected to the third fixing mechanism 60; the third fixing mechanism 60 is configured as a C-shaped piece, one end of which is connected to the I-shaped piece, and the other end is connected to the purlin 10; the I-shaped piece and the C-shaped piece can save materials while ensuring mechanical strength, and the support column of the I-shaped piece is arranged in the middle to maintain the flatness of the raised portion 30, so that the C-shaped piece can be easily fixed on the purlin 10.

[0039] like Figure 1 , Figure 3 As shown, a vapor barrier layer 24 is arranged between the thermal insulation layer 23 and the lower plate layer 22 and between the thermal insulation layer 23 and the upper plate layer 21, and the vapor barrier layer 24 includes an aluminum foil layer and a polyethylene woven cloth layer; the polyethylene woven cloth layer is arranged on the side close to the thermal insulation layer 23; the vapor barrier layer 24 can isolate water vapor and extend the service life of the overall structure.

[0040] The thermal insulation layer 23 is provided with at least two layers of thermal insulation cotton, and the two layers of thermal insulation cotton are overlapped with each other in a staggered manner; the staggered overlap of multiple layers of thermal insulation cotton can avoid the formation of gaps at the seams of the thermal insulation cotton, which may reduce the thermal insulation effect and cause condensation.

[0041] The spacing between adjacent purlins 10 does not exceed 1.5 meters, ensuring that the roof has sufficient support to avoid dents caused by long-term use.
