Description
Technical field
The utility model belongs to building material field, is specifically related to a kind of being connected firmly and the good concrete prefabricated board of shock resistance.
Background technology
At present, floor for building on market mostly is cassette ceiling, its upper and lower plates face is smooth, there is a plurality of hole centre, only connects by adhesive mortar and passes through seam, add that mortar saturability is poor in the process of building by laying bricks or stones between adjacent floor deck, therefore the connection between floor and floor is insecure, and there is shock resistance difference in present cassette ceiling used, heat insulation effect poor mostly, the problems such as soundproof effect is not enough.
Utility model content
The utility model carries out to solve above-mentioned problem, and object is to provide a kind of and is connected firmly and the good concrete prefabricated board of shock resistance.
The utility model provides a kind of being connected firmly and the good concrete prefabricated board of shock resistance, it is characterized in that: body, in rectangular-shaped; Connecting portion, comprise: at least one is arranged on the connector at the two ends in body width direction, connector comprises a boss and a groove between body and boss, boss and groove match, wherein, when concrete precast floor is intermediate plate, respectively there is a connector at the two ends of the width of body, mutually be fitted together to by connector between two intermediate plates, when concrete precast floor is side plate, one end of the width of body has connector, mutually chimeric by connector between side plate with intermediate plate.。
Concrete prefabricated board of the present utility model can also have such feature: wherein, and when concrete precast floor is intermediate plate, two connectors are in a center of symmetry.
Concrete prefabricated board of the present utility model can also have such feature: wherein, and connector place is embedded with reinforcing bar.
Concrete prefabricated board of the present utility model can also have such feature: wherein, and the hollow parts in body is filled with insulation or sound insulation materials.
Concrete prefabricated board of the present utility model can also have such feature: wherein, and boss is wedge shape platform, and wedge shape platform is right-angled trapezium shape.
The effect of utility model and effect
Concrete prefabricated board involved by the utility model, because concrete prefabricated board comprises body and connecting portion, connecting portion comprises the connector that at least one is arranged on the two ends in body width direction, connector includes a boss and a groove matched with boss between body and boss, therefore, mutually can be fitted together to by connector between different concrete prefabricated boards, thus two concrete prefabricated boards are interconnected, therefore, the fastness connected between concrete prefabricated board is between two strengthened, and has anti seismic efficiency.
Accompanying drawing explanation
Fig. 1 be in embodiment of the present utility model concrete prefabricated board as the structural representation of intermediate plate;
Fig. 2 be in embodiment of the present utility model concrete prefabricated board as the structural representation of side plate; And
Fig. 3 is the interconnective structural representation of concrete precast floor in embodiment of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reach object and effect is easy to understand, following examples are specifically addressed concrete precast floor of the present utility model by reference to the accompanying drawings.
Concrete prefabricated board, for laying the laying of the horizontal plane of sewer and house, first customizes hollow mould with plank, in the hollow part distribution of model after reinforcing bar, fills hollow parts with cement, waits dry rear knock-off plank to obtain.
Fig. 1 be in embodiment of the present utility model concrete prefabricated board as the structural representation of intermediate plate.
As shown in Figure 1, the concrete precast floor 100 as intermediate plate comprises: body 150 and two connectors, 110, two connectors 110 are separately positioned on body 150 two ends in the width direction, and two connector 110 settings in a center of symmetry.Body 150 and two connectors 110 are formed as one.
Body 150 has the hole 140 that 4 are traversed body 150 length direction, loads insulation, sound insulation materials, can improve the insulation of floor, soundproof effect in hole 140.
For the connector 110 on the left side in Fig. 1, the assembly that the cross section of connector 110 is made up of rectangle 111 and right-angled trapezium 112, the long base of right-angled trapezium 112 overlaps with the long limit of rectangle 111 and the broadside of the right-angle side of right-angled trapezium 112 and rectangle 111 forms straight line, another broadside of rectangle 111, see with the direction in Fig. 1, this broadside is the right broadside of rectangle 111, the right broadside of rectangle 111 overlaps with the broadside of body 150 cross section, another long limit of rectangle 111, see with the direction in Fig. 1, this long limit is the upper long limit of rectangle 111, the upper long limit of rectangle 111 and the upper long limit of body 150 cross section form straight line.Therefore, connector 110 and body 150 constitute the structure that has trapezoidal groove.
Figure 120 is the centrosymmetric image of connector 110, and figure 120 and connector 110 can form a cuboid identical with body 150 thickness, therefore, mutually can be fitted together to by connector 110 between two concrete precast floors 100, namely the trapezoid boss of the connector 110 of a concrete precast floor 100 can match with the trapezoidal groove of the connector 110 of another concrete precast floor 100.
In addition, at connector 110 and body 150 junction and dotted line 130 place, be also embedded with reinforcing bar, thus the fastness between connector 110 and body 150 can be increased.
Concrete precast floor 100 is similar with the structure as side plate as intermediate plate, adopts identical label for identical structure, and omits identical explanation.
Fig. 2 be in embodiment of the present utility model concrete precast floor as the structural representation of side plate.
As shown in Figure 2, the concrete precast floor 200 as side plate comprises: body 150 and a connector 110, connector 110 is arranged on one end of body 150.Body 150 and connector 110 are formed as one.Can be mutually chimeric by connector 110 between concrete precast floor 200 with concrete precast floor 100.
Fig. 3 is the interconnective structural representation of concrete prefabricated board in embodiment of the present utility model.
Concrete prefabricated board 100 two ends as intermediate plate are mutually chimeric by connector 110 with two concrete prefabricated boards 200 as side plate respectively, therefore, connection between precast plate and precast plate is more firm, and also saves the use amount of adhesives, and too increases anti-seismic performance.
The effect of embodiment and effect
Concrete prefabricated board involved by the present embodiment, because concrete prefabricated board comprises body and connecting portion, connecting portion comprises the connector that at least one is arranged on the two ends in body width direction, connector includes a boss and a groove matched with boss between body and boss, therefore, mutually can be fitted together to by connector between different concrete prefabricated boards, thus two concrete prefabricated boards are interconnected, therefore, the fastness connected between concrete prefabricated board is between two strengthened, and has anti seismic efficiency.
In the present embodiment, because hollow parts is filled with insulation or sound insulation materials, so, there is the function of insulation and sound insulation.
In the present embodiment, connector place also embedded bar, therefore, can fastness between strengthening connection body and body.
Above-mentioned embodiment is preferred case of the present utility model, is not used for limiting protection domain of the present utility model.
