Detailed description of the invention
As shown in Figures 1 to 5, composite partition is spliced with lower joint partition board 11 by upper joint partition board 10, and upper joint partition board and concrete roof 20 are fixed, and lower joint partition board and concrete floor 21 are fixed,
Fig. 1 shows the syndeton of joint partition board and lower joint partition board, described upper joint partition board 10 bottom is provided with connecting pin 102, described lower joint partition board 11 top is provided with steel pin plate 112, described connecting pin 102 is provided with forward sawtooth 103, cotter way is provided with in described steel pin plate 112, be provided with reverse sawtooth 113 in described cotter way, described connecting pin 102 and steel pin plate 112 fastening as a whole by being connected of forward and reverse sawtooth.Described upper joint partition board 10 top is provided with link slot 101, and be equipped with steel plate in described upper link slot, described connecting pin 102 is fixed in link slot.Described lower joint partition board 11 bottom is provided with lower link slot 111, and be equipped with steel plate in described lower link slot, described steel pin plate 112 is located in lower link slot, is provided with spring 114 between described two ends, steel pin plate left and right and lower link slot left and right sides wall.Described forward sawtooth is knuckle-tooth, the described reverse sawtooth side of being tooth.
Well in advance saves the link slot of partition board and lower joint partition board, then connecting pin and steel pin plate are embedded in the link slot of partition board termination, when upper joint partition board is connected with lower joint partition board, connecting pin inserts in the cotter way of steel pin plate, forward and reverse jigsaw fit connects, simultaneously because the steel pin plate left and right sides is fastening by telescopic spring, thus upper joint partition board and lower joint partition board are linked to be entirety.
The present invention employs the mechanical seamless theory of engagement and is connected between upper joint partition board with lower joint partition board, namely inserting with the zigzag connecting pin of band is embedded in the lower link slot of lower joint partition board termination, connecting pin be hidden in lower link slot with flexible fastening by spring of the steel pin plate of reverse saw flute profile, both are engaged each other, thus two sections of partition boards are linked to be entirety, it can not only reliably transmission of pressure, can also bear moment of flexure, shearing and pulling force, this structure successfully solves the construction difficult problem of slab-joint cracking.
In addition, this partition board comprise plant fiber-cement panel and be located at partition board inner chamber that plant fiber-cement panel surrounds in fibrous concrete.Be provided with dividing plate in described partition board inner chamber, partition board inner chamber is divided into several holes by described dividing plate, and described fibrous concrete is filled in hole.The shape of described hole is regular hexagon, and described hole is arranged in cellular.Be provided with interface channel between described hole, in described interface channel, be embedded with bar planting.
The present invention improves the core material of partition wall on the basis of traditional partition board, be provided with fibrous concrete as core body synthetic materials, in addition, owing to being provided with diaphragm structure further, the performance requirements such as satisfied sound insulation, insulation, fire prevention, waterproof, environmental protection make partition wall have tension, compressive property further, also improves anti-seismic performance.
As shown in Figure 2, upper joint partition board 10 top is fixed by L shape steel plate 201 and concrete roof 20, and both sides, described upper joint partition board 10 top are respectively provided with between L shape steel plate 201, a L shape steel plate and concrete roof and are fixed by nailing 202.Filling concrete mortar 203 in gap between upper joint partition board top and concrete roof.90 degree of corners between described upper both sides, joint partition board top and concrete roof are additional is pasted with lengths 204.
As shown in Figure 3, L shape steel plate between upper joint partition board 10 and concrete roof 20 also can be arranged on joint partition board top middle portion, upper joint partition board top middle portion is provided with a dovetail groove, and L shape steel plate one side is located in dovetail groove, filling concrete mortar 203 in dovetail groove.
As shown in Figure 4, lower joint partition board bottom is fixed by L shape steel plate 201 and concrete floor 21, filling concrete mortar 203 in the gap between lower joint partition board bottom and concrete floor.Lower joint partition board center bottom is provided with a dovetail groove, and L shape steel plate one side is located in dovetail groove, filling concrete mortar 203 in dovetail groove.Concrete floor is equipped with surface layer 210.
As shown in Figure 5, when lower joint partition board and concrete floor are constructed, both sides, lower joint partition board 11 bottom are carried on the back tightly by timber wedge 211, then filling concrete mortar 203 in gap, are withdrawn from by timber wedge after finally arriving intensity.
