Description

Sandwich gypsum block

Technical field

The utility model relates to gypsum production field, especially a kind of sandwich gypsum block.

Background technology

At present, normal adopt multiple industrial by-products as: desulfurated plaster, ardealite etc. are produced " gypsum block ".And such gypsum block product is applied in frame structure building lightweight inner partition wall, for a large amount of industrial residue of dissolving, curbing environmental pollution has played important function.But " gypsum block " structure species used at present is more single, is " hollow plaster block " that hole is smoked in inside---the object done like this only has one, in order to weight reduction is to meet light building material requirement.Therefore early stage solid block is eliminated.These years along with technological progress and equipment manufacturing industryization upgrading, the release of large-scale high power plant has promoted production and the application of " hollow plaster block " product further.

Although hollow plaster block achieves loss of weight and saves the object of material, also bring open defect: sound insulation value is too poor, and general 100 mm of thickness hollow plaster block sound insulations are only about 25 decibels, have a long way to go with the standard of house sound insulation 45 decibels simultaneously.In order to improve soundproof effect, people adopt again the simple approach increasing thickness of wall body.But the mode of so simple adjustment thickness, can allow later stage operation increase thus allow artificial and material cost increase substantially, being unfavorable for the production and operation of enterprise.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of not increasing material consumption and mass area ratio, under prerequisite that little amplitude raises the cost, can improve the sandwich gypsum block of the sound insulation value of gypsum block.

The utility model solves the technical scheme that its technical problem adopts: sandwich gypsum block, comprise gypsum block and be arranged at the cavity in described gypsum block, be provided with at least one in described cavity and strengthen floor, be provided with filler in described cavity and described filler and cavity inner wall are fully bonding.

Further, the two ends of described enhancing floor are connected with the upper surface of gypsum block and soffit respectively.

Further, described enhancing floor is two, and described enhancing floor is for be divided into three equal parts by cavity.

Further, the sidewall of described gypsum block is provided with the sunk coak and tenon groove that match each other.

Further, described gypsum block is rectangle, and described sunk coak and tenon groove are arranged on two relative faces of sidewall respectively.

Further, described filler is the mixture of gypsum material oar and lightweight aggregate particle.

Further, described lightweight aggregate particle is the lightweight aggregates such as polystyrene foam particles, haydite, expanded perlite granule.

The beneficial effects of the utility model are: because cavity inside of the present utility model adopts the mode strengthening floor and filler, not only can ensure the firm of gypsum block structure, also can improve the soundproof effect of gypsum block greatly.In addition, property indices of the present utility model is better than common hollow plaster block greatly, and superiority of effectiveness is obvious, and particularly identical size of capacity apparatus for production line investment is lower.The utility model is applicable to the application higher to soundproof effect requirement.

Accompanying drawing explanation

Fig. 1 is sectional view of the present utility model.

Fig. 2 is lateral view of the present utility model.

Fig. 3 is top view of the present utility model.

Be labeled as in figure: gypsum block 1, enhancing floor 11, tenon groove 12, sunk coak 13, upper surface 14, soffit 15, sidewall 16, cavity 2, filler 3.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further illustrated.

Sandwich gypsum block as shown in Figure 1, Figure 2, Figure 3 shows, the cavity 2 comprising gypsum block 1 and be arranged in described gypsum block 1, be provided with at least one in described cavity 2 and strengthen floor 11, be provided with filler 3 in described cavity 2 and described filler 3 is fully bonding with cavity 2 inwall.

With regard to production and processing mode of the present utility model, two kinds: one can be had to be pour into a mould sandwich after first doing shell; Two is that first shaping sandwich pours into a mould shell again.Can certainly adopt platform flat-die mode laminated pouring, just the many efficiency of flow process is not high.Preferred production decision is: adopt flat-die moulding by casting or continuous extrusion way to produce " gypsum material oar+lightweight aggregate particle " the compound sandwich obturator that conforms to quality requirements, until described compound sandwich harden to there is some strength (do not affect move, need not wait for bone dry) time, assemble mould by platform flat-die mode, then place compound sandwich and accurately location, then disposal pouring gypsum material oar, then arrange flat-die upper surface, then realize solidification, preliminarily dried after cutting, finally put in storage to bone dry and be finished product.In order to enhance productivity further, " in groups longitudinal formwork erection " (formwork erection overlapping arrangement) mode can be adopted, once-cast 20 groups.Production capacity budget is: be 2550 millimeters of designing moulds with formwork erection height, every mould can produce the stock size building block 5 pieces of 666 (wide) × 500 (height) × 100 (thick) mm, 20 groups of formwork erection meters 100 pieces, amount to 33 flat ms/h (within wherein, die assembly, cast cured explosive, the demoulding amount to 1 hour).Every mold car 8 hours production capacities can reach 260 square meters/sky (in 8 hours), configure many molds car and can realize scale volume production.In addition, the filler of the application is not that simple physics is filled, but has certain compressive strength and have the filler of abundant adhesive strength with building block envelope structure.

In order to strengthen structural strength of the present utility model, the two ends strengthening floor 11 can be selected to be connected with the upper surface 14 of gypsum block 1 and soffit 15 respectively.As shown in Figure 1, strengthen floor 11 according to the mode be connected with the upper surface 14 and soffit 15 of gypsum block 1, the bearing capacity bearing gypsum block 1 that can be best, ensure the structural stability after installing.Further, as shown in Figure 1, preferably strengthening floor 11 is two, and described enhancing floor 11 is for be divided into three equal parts by cavity 2.

In addition, the sidewall 16 of described gypsum block 1 is provided with the sunk coak 13 and tenon groove 12 that match each other.As Fig. 1 and Fig. 3, sunk coak 13 and tenon groove 12 both facilitated building construction, were also conducive to improving joint strength, easily realized during this structure continuous seepage to the unrestricted obstacle of die apparatus.General, gypsum block 1 is chosen as rectangle, described sunk coak 13 and tenon groove 12 are arranged on two relative faces of sidewall 16 respectively, as shown in Figure 3, the linking that such sunk coak 13 and the arrangement of tenon groove 12 can well realize gypsum block 1 is installed, and ensures the structural stability after installing.

General, preferred filler 3 is the mixture of gypsum material oar and lightweight aggregate particle, and further, lightweight aggregate particle is the lightweight aggregates such as polystyrene foam particles, haydite, expanded perlite granule.Filler itself, except having sound insulation function, also gives certain intensity during best mix-design, Kang pressure Du≤3.5MPa is best.

The utility model property indices is better than common hollow plaster block all greatly, and its integrated cost is a little more than building-block, but superiority of effectiveness is obvious.Particularly identical size of capacity apparatus for production line investment is lower.
