Prefabricated wood composite floor structure
Technical field
The present invention relates to a kind of building structure, be specifically related to a kind of novel prefabricated wood composite floor structure, main (but not exclusively) is used as timber buildings room (building) panel.
Background technology
Wooden frame structure mostly is the low-rise building of 1~3 layer at present, and along with the expansion of population growth, construction land minimizing and wooden construction range of application, timber buildings on the middle and senior level will become the focus of development gradually.Timber buildings on the middle and senior level, compared to traditional timber buildings, by adopting the form of construction work of member prefabrication on-site consolidation, can complete the construction and installation in house more efficiently, fast, easily.Timber buildings after completing has low-carbon environment-friendly, green comfortable premium properties, can ensure comfortableness and safety that people live, very important and necessary.
The wood superstructure is the important step in timber buildings design, compared to concrete structure and steel work, wooden superstructure bending resistance a little less than, easily under the vertical force effect, moderate finite deformation occurs, thereby people are normally used and live and can cause very large puzzlement.Yet the combining structure that wood structure panel and joist connect into can improve the whole bending resistance of wooden superstructure.Inside fill out rock wool and can improve the heat-insulating property of superstructure, cover the fireproof performance that fire-resistant gypsum panel can improve superstructure outward.
Summary of the invention
The objective of the invention is to overcome existing wooden superstructure bending resistance deficiency, a kind of prefabricated wood composite floor structure is provided, the combining structure that adopts joist to be connected with the wood structure panel nail, improve the whole bending resistance of superstructure, in adding, fill out rock wool, cover insulation and fireproof performance that fire-resistant gypsum panel improves superstructure outward.
Technical scheme of the present invention is: a kind of prefabricated wood composite floor structure, comprise wood structure panel, joist, stull, rock wool and fire-resistant gypsum panel, described wood structure panel is arranged in the upper and lower both sides of described joist, the wood structure panel arranged beneath of joist downside has fire-resistant gypsum panel, between two Pin joists, be furnished with stull, be filled with rock wool in the space that described joist and wood structure panel form.
As preferably, described bay of joist is 480mm.
As preferably, between described joist and wood structure panel, adopt steel nail to be connected, steel nail is along joist length direction layout, and steel nail is evenly arranged with the spacing of 80mm.Between wood structure panel and fire-resistant gypsum panel, adopt nail to be connected.
As preferably, described joist and stull are material grade III c or its above dimension stock.
As preferably, described wood structure panel is structural plywood or oriented wood chipboard, and thickness is 12mm.
As preferably, described flame-retarded gypsum plate thickness is 15mm.
As preferably, described joist, stull and wood structure panel adopt moisture content to be less than or equal to 20% material.
Useful result of the present invention is: the combined type that the present invention adopts wood structure panel to be connected with joist nail, improved the whole bending resistance of superstructure; Meet the fire safety requirement of timber buildings; Product can carry out assembling production in factory, and quality is good and precision is high, and the prefabricated wood composite floor structure of this invention can be widely used in timber buildings.
The accompanying drawing explanation
Fig. 1 is the overall schematic of the prefabricated wood composite floor structure of the present invention;
Fig. 2 is the side sectional view of the prefabricated wood composite floor structure of the present invention.
The specific embodiment
The present invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2: a kind of prefabricated wood composite floor structure, comprise wood structure panel 1, joist 2, stull 3, rock wool 4 and fire-resistant gypsum panel 5, described wood structure panel 1 is arranged in the upper and lower both sides of described joist 2, wood structure panel 1 arranged beneath of joist 2 downsides has fire-resistant gypsum panel 5, between two Pin joists 2, be furnished with stull 3, be filled with rock wool 4 in the space that described joist 2 and wood structure panel 1 form.
Described prefabricated wood superstructure length * wide * height is of a size of 2440mm * 1220mm * 128mm.Described joist 2 spacings are 480mm.Between described joist 2 and wood structure panel 1, adopt steel nail to be connected, steel nail is along joist 2 length directions layouts, and steel nail is evenly arranged with the spacing of 80mm.Between wood structure panel 1 and fire-resistant gypsum panel 5, adopt nail to be connected.Described joist 2 and stull 3 are material grade III c or its above dimension stock.Described wood structure panel 1 is structural plywood or oriented wood chipboard, and thickness is 12mm.Described fire-resistant gypsum panel 5 thickness are 15mm.Described joist 2, stull 3 and wood structure panel 1 adopt moisture content to be less than or equal to 20% material.
It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.In the present embodiment not clear and definite each ingredient all available prior art realized.
