Description

A kind of fire proof construction of light transmission platform or light shaft

Technical field

The utility model is related to build, the fire proof construction of especially a kind of light transmission platform or light shaft.

Background technology

Building such as market, mansion etc. can all use transparent platform using glass as main material or light shaft to realize Daylighting effect can greatly reduce the dependence to electric lighting, energy saving, and illuminating effect is more natural, bright.

Building structure for this type is needed to meet certain bearing capacity, and be must assure that when its is chipping not It can fall off, avoid causing life threat, therefore the interlayer tempered glass of its generally use high intensity to crowd below.

But tempered glass does not have flameproof effect, is merely capable of bearing the difference variation within 250 degrees Celsius, and existing rank Section to transparent platform or light shaft also without relevant fire protection requirement, security performance still Shortcomings.

And when the grouting flameproof glass on existing market being used to substitute interlayer tempered glass, in addition to rigidity, intensity can not Except problem up to standard, also as being emulsion form fireproof gum in its interlayer, do not have the anti-of interlayer tempered glass when fire fires Fall off characteristic, fall off open wide after platform or light shaft can form stack effect, instead accelerate fire behavior sprawling, cause more tight The human injury of weight and economic loss.

For overcome the deficiencies in the prior art, the utility model provides the fire proof construction of a kind of light transmission platform or light shaft.

Technical solution adopted by the utility model to solve its technical problems is：

A kind of fire proof construction of light transmission platform or light shaft, including frame and it is embedded in fire prevention glass on said frame Glass, the flame resistant glass include at least two layers of toughened glass layer, wherein there are two edges between the adjacent toughened glass layer Edge is arranged with heat resistant plastice gasket and forms hollow interlayer, the hard fire prevention formed filled with hard transparent material in the interlayer Layer.

The hard transparent material is crystalline silica.

The hard fireprotection layer is multilayer, is now isolated by tempered glass substrate between two layers adjacent of hard fireprotection layer.

The toughened glass layer is the doubling glass being made of at least two layers of tempered glass substrate.

The flame resistant glass has three layers or three layers or more of toughened glass layer, wherein there are two the adjacent tempering glass It is equipped with cavity between glass layer and forms air layer.

The frame includes supporting rack, and support frame as described above is equipped with the step of flame resistant glass described in bearing, and passes through top Buckle realize fix.

The trim for having masking fastener is fastened above the buckle.

Support frame as described above surface is equipped with fire-proof plate.

Step is equipped between the air layer and the hard fireprotection layer, the size of the step corresponds to the buckle setting It is concordant to realize.

The utility model has the beneficial effects that：Between the toughened glass layer of multilayer, pass through hard transparent material such as crystallization two The hard fireprotection layer bonding that silica is formed, which combines, forms flame resistant glass, can have excellent fire protecting performance, even and if occurring Situation is fired, hard fireprotection layer still can effectively be adhered the toughened glass layer of both sides, glass will not occur and fall off, and meet safety and want It asks, while the hardness of hard fireprotection layer is high, the structural strength of flame resistant glass can be further strengthened, to meet platform or zenith The intensity requirement of light shaft.

Specific implementation mode

Referring to Fig.1, the fire proof construction of Fig. 2, a kind of light transmission platform or light shaft, including frame 1 and be inlaid on frame 1 Flame resistant glass 2, flame resistant glass 2 includes at least two layers of toughened glass layer 3, wherein there are two adjacent toughened glass layer 3 it Between along edge be arranged with heat resistant plastice gasket 4 into hollow interlayer, the hard fire prevention formed filled with hard transparent material in interlayer Layer 5.

Between the toughened glass layer 3 of multilayer, the bonding of hard fireprotection layer 5 formed by crystalline silica combines formation Flame resistant glass can have excellent fire protecting performance, even and if fire situation, hard fireprotection layer still can effectively be adhered both sides Toughened glass layer 3, glass will not occur and fall off, meet safety requirements, while the hardness of hard fireprotection layer 5 is high, can be into one Step reinforces the structural strength of flame resistant glass, to meet the intensity requirement of platform or zenith light shaft.

With reference to Fig. 3, in order to reinforce fire protecting performance, multilayer hard fireprotection layer 5 can be set, and prevent fires in two layers adjacent of hard It is realized and is isolated by tempered glass substrate 31 between layer 5, meet the different fire-protection standards of different fields of employment.

And toughened glass layer 3, be the doubling glass being made of at least two layers of tempered glass substrate 31, by substrate it Between PVB glued membranes etc. realize and can be effectively adhered when radiation protection, heat-insulated and soundproof effect, and glass substrate rupture, will not be formed Fall off fragment.

With reference to Fig. 4, further, flame resistant glass 2 has three layers or three layers or more of toughened glass layer 3, in addition to therein Except two layers of formation fire proof construction, it is equipped with cavity also between the adjacent toughened glass layer 3 of another two and forms air layer 6, it can Realize sound insulation, heat insulation.

With reference to Fig. 6, and it is embedded in the light transmission platform or light transmission crib frame 1 of flame resistant glass comprising with the fixed support of wall Frame 11, supporting rack 11 are in inverted T shaped or L-type, are formed with the step of bearing flame resistant glass 2 thereon, then by the buckle 12 of top with The installation of supporting rack 11 is fixed, and flame resistant glass sandwiched is made to realize fixation on it.

12 top of buckle, which fastens, trim 13, can cover the fastener between buckle 12 and supporting rack 11, more beautiful It sees.

And it is equipped with fire-proof plate 7 on 11 surface of supporting rack, the fire protecting performance of frame 1 can be effectively improved, metal frame is avoided Frame occurs under high temperature environment.

In addition, with reference to Fig. 5, for aesthetics, step is equipped between the air layer 6 and hard fireprotection layer 5 of flame resistant glass, and So that the size of step is corresponded to the setting of buckle 12, realizes that flame resistant glass is concordant with frame 1, the use for more meeting light transmission platform is wanted It asks.

The light transmission platform of the utility model or the fire proof construction of light transmission well make it by the improvement to frame 1 and glass Have fire protecting performance, will not there is a situation where glass to fall off, meet safety requirements, while meeting the knot of platform or zenith light shaft Structure intensity requirement.
