Abstract
The invention discloses a building gas explosion wall structure, which comprises a light steel keel skeleton, wherein the gaps in the skeleton are filled up with a filler; and at least one of the two sides of the skeleton is adhered with more than one layer of gypsum board. By adopting a light steel keel and the pressure-resistance and fireproof gypsum board and by other reinforcing measures, the pressure bearing capacity of the partition wall structure disclosed by the invention can reach 1,200MPa, so the partition wall meets a gas extinguishing device's requirement on a pressure-bearing capacity of not less than 700MPa of the partition wall. According to the technical scheme, the adopted light steel keel gypsum board partition wall system has much lighter self weight and reduced structural load compared with a steel reinforced concrete system partition wall system. In addition, constructed by assembling semi-finished products, the structure has the advantages of small space occupation, high construction speed, less environmental pollution and the like, and is particularly suitable for partition wall systems of high-rise buildings and steel buildings.

Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of lightweight, the simple gas explosion partition wall wall body structure of construction, alleviate the finished product protection of structural load, constructability and equipment.
In order to address the above problem, to the invention provides a kind of building gas explosion wall structure and comprise: the lightgage steel joist skeleton, filling has a filler in the gap of described skeleton, and at least one side in the both sides of described skeleton is fitted with the above gypsum plank of one deck.
Preferably, described skeleton comprises C type sky keel, C type ground joist, C type centre keel and U-shaped stull keel; Described C type sky keel are arranged on the top structure of building by securing member, described C type ground joist is arranged on the polycrystalline substance of building by securing member, described C type centre keel is arranged between described C type sky keel and ground joist, described U-shaped stull keel are arranged on C type centre keel by securing member, and described U-shaped stull keel and C type centre keel form cross-well word structure in length and breadth.
Preferably, also sticked one deck anticracking wall cloth in the outside of described gypsum plank.
Preferably, described filler is rock wool or glass wool.
Preferably, the thickness of described C type sky keel, C type ground joist, C type centre keel and U-shaped stull keel is 0.1cm.
Preferably, the thickness of described filler filling is: 10cm.
Partition wall body structure of the present invention adopts lightgage steel joist, withstand voltage refractory plasterboard and other reinforcement measures, the withstand voltage that can guarantee body of wall reaches 1200MPa, can satisfy fire-smothering gear and the body of wall withstand voltage is not less than the requirement of 700MPa, and because this programme adopts the bulkhead of light-weight steel keel plaster tablet system, greatly alleviate the body of wall deadweight than steel reinforced concrete system partition wall, alleviated structural load.In addition, adopt the semiproduct fabricated construction, also have occupy little space, speed of application is fast, the advantage such as low in the pollution of the environment.
Description of drawings
Fig. 1 is keel architectural schematic of the present invention;
Fig. 2 top of the present invention connects sectional schematic diagram;
Fig. 3 is the present invention's bottom connection sectional schematic diagram;
Fig. 4 is that the present invention adopts the top of double-layer keel to connect sectional schematic diagram.
The specific embodiment
Now reaching by reference to the accompanying drawings construction embodiment is described further the present invention:
As shown in Figure 1, 2, 3, the present invention includes: lightgage steel joist skeleton 1, filling has rock wool 2 in the gap of skeleton 1, is fitted with three layers of gypsum plank 3 in the both sides of skeleton 1.In the present invention, skeleton 1 comprises C type sky keel 11, C type ground joist 12, C type centre keel 13 and U-shaped stull keel 14; C type sky keel 11 are arranged on the top structure of building by securing member 4, C type ground joist 12 is arranged on the polycrystalline substance of building by securing member 5, C type centre keel installs 13 between C type sky keel 11 and ground joist 12, U-shaped stull keel 14 are arranged on C type centre keel 13 by securing member 6, and U-shaped stull keel 14 and C type centre keel 13 form cross-well word structure in length and breadth.In addition, also sticked one deck anticracking wall cloth 7 in the outside of gypsum plank 3.
Above-mentioned securing member 4,5 adopts expansion bolt, and securing member 6 can be pulling rivet, also can adopt the fixing mode of fast-assembling clipper joint.
Above-mentioned C type sky keel 11, C type ground joist 12, C type centre keel 13 and U-shaped stull keel 14 adopt thickening type, and thickness is 0.1cm, and specification is 15*5*0.1cm.In addition, the filling thickness of rock wool 2 is 10cm.
Implement in the following order to install according to technological requirement the present invention.
A, keel system are installed, U-shaped day keel 11, ground joist 12, keelson 15 are connected with the building top sound construction according to a determining deviation with expansion bolt, then C type centre keel 13 is installed, U-shaped stull keel 14 are installed again (for strengthening sealing effectiveness, the cotton felt 19 of cushioning 10mm heavy sheet glass between keel and structural plane, because body of wall adopts sliding connection structure, therefore centre keel 13 can not be connected with day keel 11, ground joist 12, stull keel 14 also can not be connected with keelson 15, and centre keel 13 tops need be stayed 20mm to do to slide and process.Centre keel 13 is fixed with stull keel 14 use pulling rivets or fast-assembling clipper joint).
B, erection equipment pipeline, opposite house, window, place, hole carry out consolidation process, and carry out the hidden examination of keel system.
C, fill rock wool 2 (or glass wool, filling is even, closely knit, without being scattered).
D, withstand voltage refractory plasterboard 3 are installed, and with tapping screw 10, withstand voltage refractory plasterboard 3 successively are fixed on the keel system.For guaranteeing that body of wall is slidably connected, gypsum plank 3 is all fixing with keel 11,12,15, and gypsum plank 3 will reserve certain interval with structural plane, processes with sealing compound 8, and each layer gypsum plank should be avoided straight joint.
E, reinforcing angle are installed, and will be fixed according to a determining deviation through antiseptic angle steel 18 use expansion bolts.
F, subsides cracking resistance wall cloth 7 first carry out preservative treatment to the exposed junction of tapping screw 10, and seam and the pit of withstand voltage refractory plasterboard 3 are filled and led up with putty, more completely the Puttying to wall surface levelling, is pasted cracking resistance wall cloth 7.
After testing, the testing result of deformation of wall performance test of the present invention is as follows:
1200Pa 1s pressing time keeps 15s, and test specimen is without visible change;
1800Pa 1s pressing time keeps 15s, and test specimen is without visible change;
2400Pa 1s pressing time keeps 15s, and test specimen is without visible change;
3600Pa 1s pressing time keeps 15s, and test specimen is without visible change;
4800Pa 1s pressing time keeps 15s, and test specimen is without visible change.
This shows, the present invention can satisfy fire-smothering gear and the body of wall withstand voltage is not less than the requirement of 700MPa.
In sum; these are only preferred embodiment of the present invention; be not for limiting protection scope of the present invention; for example; as shown in Figure 4, keel of the present invention also can adopt the structure of double keel, therefore; all any modifications of doing within the spirit and principles in the present invention, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
