Description

A kind of door leaf

Technical field

This utility model is related to a manufacturing technology field and in particular to a kind of door leaf.

Background technology

Existing interior door, the species of exterior door door leaf have timber, steel casement door, stainless steel door, iron gate etc. by material differentiation, its Weak point is high cost, weight is big, do not prevent fires.Using anti-fire door core board (as foaming door panel) come the fire resistant doorsets manufacturing, its Adopt plank or steel plate door face board more, need between door panel and door face board to be connected using more glue, solid-filling, steel nail Anchor is tied, and causes high cost, weight big, and wooden door face board not fire resisting, low intensity, and the door face board of steel then can after baked wheaten cake Deformation is it is difficult to effectively intercept the diffusion of poison gas.

Content of the invention

In order to solve the above-mentioned deficiency of existing door leaf, the purpose of this utility model be provide a kind of with thistle board as substrate Lightweight, sound insulation, high fire resisting, the door leaf of low cost.

For achieving the above object, the technical solution adopted in the utility model is: a kind of door leaf, and its substrate is thistle board, should The outside of thistle board is covered with net muscle and back-up coat；In order to improve bulk strength, door leaf is additionally provided with multi-segment structure part, described Structural member is separately embedded in advance on door leaf side and installs the position of lockset, and each segment structure part pass through steel wire (or steel bar) with relative or Tiltedly to other structures part couple together, so pre-buried structural member is just securely fixed on door leaf substrate；Needing to pacify On the structural member of dress hinge and door closer, it is additionally provided with screw hole.

Preferably 1: described thistle board adopts cement board.

Preferably 2: described net muscle is glass fiber mesh or the high grid cloth of other intensity.

Preferably 3: described back-up coat is baking-free ceramic.

Preferably 4: described structural member is channel-section steel.

This utility model has the advantages and positive effects that: because substrate is thistle board, there are airtight bubble, institute in the inside Can be slower with conduction heat transfer, heat-resisting quantity is higher, integrates fire prevention, sound insulation, insulation advantage.This utility model door leaf density Low, light weight, easily carrying, easily construction, safety and environmental protection, can mitigate building loading, reduce building cost, and it is existing no to return halogen As, durable, weather-proof, ageing-resistant, environmental protection, nontoxic, tasteless, odorless, pollution-free, good waterproof performance, do not absorb water, do not soften, not mouldy, Water steeps harder and harder, long service life.Substrate adopts cement board fireproofing inorganic material, belongs to a1 level fire proofing material, has good Fire resistance, refractoriness more than 1000 DEG C, indeformable under high temperature, not warpage, do not burn, and do not have toxic gas discharge, belong to In safety environment-friendly materials, fully meet the fire resistant requirements of fire resistant doorsets.Because the surface of substrate is covered with net muscle and back-up coat, and in advance It is embedded with the structural member connecting by steel wire, therefore resistance to compression, anti-folding, torsional strength is all higher, has reached low-density higher-strength Relatively uniform, using with transport all not easily broken, be difficult to split off, be unlikely to deform, even if foot kick also not bad.This utility model door leaf Production technology and operation are simply it is not necessary to install door face board additional to reinforce, therefore cost is lower.It can be said that this utility model door leaf It is the environmental protection door leaf of a new generation.

Specific embodiment

Below in conjunction with the accompanying drawings this utility model is further described.

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, this utility model door leaf is provided with door lock (2), door handle (2a), in door leaf also It is provided with multi-segment structure part (3a, 3b), structural member (3a, 3b) is separately embedded in advance on door leaf side and installs the position of lockset, and respectively Segment structure part (3a, 3b) is connected and strains with relative other structures part by steel wire (4), such as the structural member 3a shown in figure Connected with the structural member 3b of relative another side by steel wire (4), so pre-buried structural member (3a, 3b) is just firmly fixed On door leaf body (1).In addition, on the structural member (3a) needing to install hinge, being also preset with and the screw hole position on hinge Corresponding screw hole.Due to being embedded with structural member (3a, 3b), and by steel wire, structural member relative for door leaf both sides is connected And strain, therefore stress is more reasonable after mounting for door leaf, and the structural member (3a) at gemel connection can pass through steel wire in stress (4) pulling force above and is spread out by the structural member (3b) being delivered to opposite side, would not be drawn quick-fried, thus at the hinge of such door leaf The thistle board that is used thoroughly solving long-standing problem technical staff makes the technical barrier of door leaf as substrate.

With reference to Fig. 5, Fig. 6, this utility model door leaf connects door closer and door sensor position be also embedded with structural member (5, 6), this structural member (5,6) also by steel wire with tiltedly to other structures part couple together, such as the structural member 5 shown in figure leads to Cross steel wire with tiltedly to structural member 3a, 3b be connected, so pre-buried structural member (5) is just securely fixed in door leaf body (1) On.

With reference to Fig. 7, Fig. 8, in this utility model door leaf, pre-buried structural member (3a) is usually flute profile, generally use channel-section steel or It is converted into channel-shaped to make by iron plate, its bottom surface or side are preset with corresponding with the screw hole position on hinge or door closer Screw hole (3c).

With reference to Fig. 9, the profile of pre-buried another kind of structural member (3b) in this utility model door leaf is also flute profile, generally uses Channel-section steel or be converted into channel-shaped to make by iron plate.

With reference to Figure 10, in this utility model door leaf, pre-buried structural member (3a) passes through steel wire (4) and relative another side Structural member (3b) connects.The steel wire (4) connecting generally has 4, two, every side, and the two ends of steel wire are welded on structural member.When So can also be connected using steel bar, steel disc or iron wire, iron straps, this is just as.

With reference to Figure 11, the substrate of this utility model door leaf body (1) is thistle board (1a), and the outside of this thistle board (1a) is covered There are net muscle and back-up coat (1b).Described thistle board (1a) preferably with cement board, net muscle preferably with glass fiber mesh, plus Gu layer is preferably with baking-free ceramic, this is because glass fiber mesh has the characteristics that intensity is high, lightweight, and with baking-free ceramic clad can Material can combine very well, and forms a kind of firm composite construction plate body with foam cement substrate, have than existing its The more more preferable excellent properties of PLASTIC LAMINATED of his type.In addition imitation wood stricture of vagina, parian can be made, imitate on the surface of back-up coat The patterns such as ceramic tile, can also make various embossing patterns, to increase the aesthetic appearance of door leaf.

This utility model door leaf has that lightweight, intensity height, waterproof, fire prevention, heat conductivity be little, indeformable, halogenation, sound insulation Effect is good, low cost and other advantages, both can serve as fire resistant doorsets it is also possible to use as common door leaf, new generation of green of can yet be regarded as The door leaf product of environmental protection.
