The concrete prefabricated wall plate structure flexibly connecting
Technical field
The utility model relates to a kind of concrete prefabricated wall plate structure flexibly connecting.
Background technology
Concrete prefabricated wallboard is widely used in all kinds of buildings.But seam often will ftracture in use for some time between concrete prefabricated wallboard, gaping of joints is common fault and the technical barrier during concrete prefabricated wallboard uses.Cause the gaping of joints of concrete prefabricated wallboard to mainly contain two reasons: the one, because agent structure distortion causes wallboard gaping of joints, the 2nd, because concrete prefabricated wallboard varies with temperature, shrinkage strain causes gaping of joints.The conventional method that prevents wallboard gaping of joints adopts the method for " resisting " more, as: prefabricated panel adopts dove-tail tongue and groove, pours into high-strength grout at seam crossing, pastes the measures such as glass-fiber-fabric outward at seam crossing.Because the means of " resisting " can not discharge additional heavily stressed that prefabricated panel distortion produces, so cracking resistance actual effect is unsatisfactory.And, adopt these traditional rigid joints after prefabricated panel will form an entirety, can not disassemble and reuse again.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of concrete prefabricated wall plate structure flexibly connecting, the seam of concrete prefabricated wallboard is become to be flexibly connected, seam has very large deformability, can regulate the distortion of wallboard, seam no longer ftractures, and adopts after flexible joint, and prefabricated panel can also be disassembled and reuse.
To achieve these goals, the technical solution used in the present invention is a kind of concrete prefabricated wall plate structure flexibly connecting, comprise two concrete prefabricated wallboards and flexible adhesive sealant, between two concrete prefabricated wallboards, pass through flexible adhesive sealant, two described concrete prefabricated wallboards are equipped with tongue and groove, between two tongue and grooves, are built-in with hollow rubber flexible pipe.
Described tongue and groove section is trapezoidal, and outer imperial palace is little.
Compared with prior art, this concrete prefabricated wallboard flexible joint is because the seam that makes concrete prefabricated wallboard is become and flexibly connected from rigidity, seam has very large deformability, can regulate the distortion of wallboard, seam no longer ftractures, and after employing flexible joint, prefabricated panel can also be disassembled and reuse.
Accompanying drawing explanation

Fig. 2 is spliced the utility model structural representation.
In figure, 1, concrete prefabricated wallboard, 2, tongue and groove, 3, hollow rubber pipe, 4, flexible adhesive sealant.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Originally the concrete prefabricated wall plate structure flexibly connecting, as Fig. 2, comprise two concrete prefabricated walls 1 and flexible adhesive sealant 4, between two concrete prefabricated wallboards 1, pass through flexible adhesive sealant 4, two described concrete prefabricated wallboards 1 are equipped with between 2, two tongue and grooves 2 of tongue and groove and are built-in with hollow rubber flexible pipe 3.
Described tongue and groove 2 sections are trapezoidal, and outer imperial palace is little.
Preparation method of the present utility model, in the relative tongue and groove 2 of contiguous prefabricated wallboard, put into hollow rubber pipe 3 as shown in Figure 1, after wallboard installation in position by the mutual jam-packed of concrete prefabricated wallboard 1, as shown in Figure 2, distortion and the close combination of precast plate tongue and groove 2 after hollow rubber pipe 3 in tongue and groove 2 is squeezed, play elasticity to concrete prefabricated wallboard 1 and fill and sealing function.Finally between adjacent two concrete prefabricated walls 1, stamp flexible adhesive sealant 4, play face seal and decoration function.
