Description

Light wire sandwich panel for support construction

The utility model relates to a kind of for building, building constructions Prefabricated wall board web plate particularly, belongs to technical field of buildings.

Steel wire net rack cement light sandwiched plate is the light plate of a kind of NEW TYPE OF COMPOSITE that six the seventies grow up.It is to utilize cold group of steel wire of low-carbon (LC) to be welded into the three dimensions rack, and middle filling light thermal insulation material is made the semiproduct of certain specification, transport to the job site again, carry out the assembly unit welding by designing requirement, cement mortar is smeared in spray in the sandwiched plate two sides then, forms complete building board.Body is light because this building web plate formula sheet material has, insulation, heat insulation, insulate against sound and be convenient to the advantage of batch production system of giving and site operation, so developed very fast in recent years.

In the web plate of this class sheet material, representational have two classes: a class is referred to as Taibai panel, the another kind of 3D plate that is referred to as.Difference between the two at first is the oblique line directions difference that links two net sheets, secondly is the manufacture craft difference.The oblique silk direction of 3D plate is unidirectional in its corresponding plane, and the oblique silk of Taibo plate is flexuose.Taibai panel at first is welded into stringer with steel wire when making, the alternate repeatedly dress with central layer of stringer is added to be pressed into blanket again, and the horizontal hair of burn-oning in both sides is then made one; The 3D plate then is to be welded into plain net earlier, plain net and central layer is repeatedly installed again, and inserts oblique wire bond and is integral.Make a general survey of above-mentioned two class plates, no matter which kind of is, its oblique silk all is in the finite plane that is distributed in perpendicular to the net sheet, and the quantity on this plane is no more than the quantity of vertical hair in each net sheet.Because tiltedly silk disposes by rule like this, thereby the intensity and the globality of web plate load-bearing have been weakened.

The purpose of this utility model provides a kind of new sandwich web plate, and this web plate should have bigger load-bearing or compressive strength.

The purpose of this utility model is achieved in that the link direction and the pattern of oblique silk between two net sheets of appropriate design, makes the firm integral body of formation between the net sheet.The utility model is described in further detail below with reference to accompanying drawing.

Fig. 1 is a section of structure of the present utility model;

Fig. 2 is the A-A sectional drawing;

Fig. 3 is the B-B sectional drawing;

Fig. 4 is net sheet partial structurtes schematic diagrames;

Fig. 5 is the local a certain crosslinked system of a web plate three-dimensional signal enlarged drawing.

The utility model is made up of

net sheet

1,2 and central layer 3 of being clipped in the middle of it, and described net sheet is to be welded into the plain net that intersects anyhow with steel wire, and then links together with oblique.Significant improvement of the present utility model is, with the oblique silk that plays the binding effect be divided into some groups identical, be distributed on the crosslinked system between the net sheet, each crosslinked system comprises four tiltedly silks, they are respectively with the intersection point O that is formed by vertical hair and horizontal hair quadrature in its respective regions ₁With O ₄, O ₂With O ₃, O ₅With O ₈, O ₆With O ₇Weld together.

Screen plate with sandwich in the utility model both can be used as wallboard, also can be used as floor plate, and therefore, its specification is also corresponding to its applicable situation and difference.If as wallboard, then its length should be selected by building room height, is 2.7-3.6 rice such as the length that can make screen plate with sandwich, width can be 0.7-2.4 rice.After the web plate specification is determined, the also essential spacing of determining between adjacent vertical hair and the horizontal hair, generally can in the 5-10 cm range, select, can determine the horizontal hair that each net sheet is required and the quantity of vertical hair like this, then these steel wires are welded into plain net, central layer 3 on the therebetween of two net sheets, become an integral body with oblique wire bond between the net sheet.So-called crosslinked system is these that be divided into, mutually the same, the most basic connection unit of oblique silk by certain rule configuration, and these crosslinked systems weld together the intersection point that is allocated to it on the net sheet.Oblique silk in the crosslinked system becomes stereoscopic configurations, promptly every tiltedly silk be not in a plane vertical, to dispose resembling traditional product with the net sheet, but in clinoplain, dispose.From the perspective view of Fig. 5, can be clear that this structure Design characteristics (wherein, heavy line is represented the steel wire of net sheet 1, and thick chain-dotted line is represented the steel wire of net sheet 2, and the dotted line representative is silk tiltedly).P, Q represent the vertical hair of

net sheet

1,2 respectively, and a, b then represent its horizontal hair respectively, and O1-8 is the net sheet intersection point that welds with certain crosslinked system, tiltedly silk O ₁O ₄And O ₂O ₃In a plane, and oblique silk O ₅O ₈With O ₆With O ₇Then in another plane, in other words, the oblique silk in each crosslinked system is to be distributed in the plane of two intersections.This design feature is strengthened web plate integraty of the present utility model just, and its anti-level and vertical direction intensity of force also improve greatly, thereby for to lay the foundation as load-bearing wall panel.

When oblique wire bond being connected on the net sheet intersection point, silk all is welded in a bit because the horizontal hair vertical hair reaches tiltedly, thereby causes welding spot size excessive, and influence its intensity, therefore, the oblique wire bond contact in the utility model can be chosen in and be positioned near the vertical hair of intersection point, also may be selected on the horizontal hair.Thereby avoided above-mentioned adverse effect.

In the utility model, the number of crosslinked system is many more, and the intensity of its web plate is big more.Therefore, can be according to the intensity needs of web plate diverse location in building, its number of choose reasonable.In general, guarantee all to have a tiltedly cross-linking coefficient order of silk binding on each intersection point, its minimum value is a web plate number of hits purpose 1/12nd.

Cold group of steel wire of the optional low-carbon (LC) of steel wire in the utility model, the optional 2-5 millimeter of diameter, light core plate can be selected polystyrene foam plastics, rock wool or glass wool for use, and its thickness is about the 50-70 millimeter.Spacing between two net sheets can be selected in 90-110 millimeter scope.Vertical hair and horizontal hair on each net sheet are crossed as rectangle, general optional square, and its length of side can be selected in 50-70 millimeter scope.

The edge of sandwich web plate can add the some twines perpendicular to the net sheet of weldering, so that with perimeter reinforcement.

Press the screen plate with sandwich that the utility model is made, have the following advantages: 1, steel using amount is few, compares with general reinforced concrete wall, can save steel 2/3rds; 2, from heavy and light, compare with whole brick wall, can reduce weight 54-76%; 3, good heat preservation performance, its thermal resistance are 0.84m²/ W is better than the heat insulation effect of two-and-a-half brick wall; 4, intensity height, this is the maximum characteristics that the utility model is better than other like product. Because the oblique silk of the crosslinked system of stereoscopic configurations, thereby make two net sheets form a firm integral body. Make it have the intensity of enough horizontal and vertical directions. Thereby make the utility model both can be used as general exterior-protecting wall panel web plate, again can be as the web plate of load-bearing wall panel, for building a building, whole assembled from now on lays the foundation.
