Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of concrete prefabricated board and its installation method, to facilitate installation
Construction, and promote the connection integrity and safety of prefabricated superimposed sheet and surrounding member.
In order to solve the above-mentioned technical problem, technical scheme is as follows:
A kind of concrete prefabricated board, including concrete prefabricated board ontology, be embedded in the concrete prefabricated board ontology to
Few 2 truss arranged in parallel, the truss expose to concrete prefabricated board ontology upper section;The concrete is pre-
The plate end of making sheet does not go out muscle;Groove, the top surface of the groove and the top surface of concrete prefabricated board ontology are equipped between adjacent truss
Perforation, the end face of the groove and concrete prefabricated board ontology are penetrated through along a certain end face of truss length direction, the depth of groove
Less than the thickness of concrete prefabricated plate body, size of the groove on the direction vertical with truss length direction is 450-600mm.
Further, the depth of groove is 0.4-0.6 times of concrete prefabricated board body thickness.
Further, the depth of groove is 25-35mm, is further 30-35mm.
Further, the truss includes 2 the first transverse steels that are arranged in parallel and being located in the same horizontal plane
With the second transverse steel being set to above 2 first transverse steels, second transverse steel and the first transverse steel are mutual
In parallel, it is connected respectively by more oblique reinforcing bars between the second transverse steel and 2 first transverse steels, forming cross section is in
The truss structure of triangle.
Truss can enhance concrete prefabricated plate body stiffness by itself along laterally (length direction) setting of concrete prefabricated plate body;
In addition, new-old concrete can be connected, enhance the binding force between concrete prefabricated plate body and last layer
Further, the top surface of the concrete prefabricated board ontology is equipped with multiple suspender members.Further, multiple suspender members
It is arranged in row, is divided into the two rows being parallel to each other, facilitates lifting.
Further, more first longitudinal direction reinforcing bars and Duo Gen third transverse direction steel are embedded in the concrete prefabricated board ontology
Muscle, the first longitudinal direction reinforcing bar and third transverse steel are arranged in a crossed manner in 90 °.
Further, the suspender member includes the U-shaped hanging ring of back-off, and the bottom end of hanging ring, which is connected with, to be extended transversely
It stretches one's legs, described stretch one's legs protrudes into the lower section of first longitudinal direction reinforcing bar, guarantee the bonding strength of suspender member and concrete prefabricated plate body, with
Realize safe handling.
Further, the perforation for being connected to the adjacent grooves is offered on the concrete prefabricated board ontology between adjacent grooves
The end face of slot, the through slot and concrete prefabricated plate body penetrates through, in this way, length bridging can be selected when arranging distribution bar
2 or 2 distribution bars with upper groove, in the horizontal direction by distribution bar be placed in through slot in, and make distribution bar across
Several grooves are connect, the connection integrity between concrete prefabricated plate body, vertical bearing carrier is further promoted, it is strong to promote connection
Degree.
The installation method of concrete prefabricated board as described above, which is characterized in that for adjacent 2 block concrete prefabricated board with
The connection of vertical bearing carrier, includes the following steps:
S1, concrete prefabricated board is lifted in place, so that end where the groove of concrete prefabricated board is held on vertical carrying
On component;
The additional bar that S2, arrangement extend transversely, so that the both ends of additional bar are respectively protruding into adjacent 2 pieces of coagulations
In the groove of native prefabricated board;
Wherein, at least 3 additional bars have been protruded into the groove of concrete prefabricated board;
S3, in each groove additional bar top layout at least 2 distribution bars extended longitudinally;
S4, longitudinally connected reinforcing bar is bound in the stirrup of vertical bearing carrier, so that additional bar is located at longitudinally connected steel
The lower section of muscle;
S5, binding simultaneously install steel bar stress in last layer;
S6, disturbing concrete form last layer, so that concrete prefabricated board, last layer and vertical bearing carrier integrally connect
It connects, to obtain superimposed sheet structure.
In this way, distribution bar both ends are respectively protruding into adjacent concrete prefabricated board, and pass through below longitudinally connected reinforcing bar,
Hoop after pouring, in the last layer on concrete prefabricated board upper layer, groove at the top of casting concrete and reinforcing bar, vertical bearing carrier
Muscle and longitudinally connected reinforcing bar form overall structure, it is ensured that the bonding strength between adjacent concrete prefabricated board.
Further, the vertical bearing carrier is bearing beam or wall.
Further, in S2, the length that the attachment reinforcing bar protrudes into groove accounts for 2/3 times of groove length or more.
Further, in S2, at least 3 additional bars are uniformly distributed in the width direction along corresponding recesses.
Further, in S3, the distribution bar bridges at least two adjacent grooves.
In the present invention, concrete prefabricated board is anchored by vertical bearing carrier (backbar or wall) using indirect overlapping mode
Afterwards in pouring concrete.Reduce the difficulty of construction at scene.In common superimposed sheet avris, i.e., the structure type of superimposed sheet of the present invention is
Several grooves (according to the actual situation) are dug with adjacent members (backbar or wall) lap-joint, but guarantee the plate body thickness at truss
With whole superimposed sheet consistency of thickness.When site operation, after concrete prefabricated board lifting in place, placed at groove scene attached
Add reinforcing bar and distribution bar, guarantees that additional bar reaches in adjacent members (backbar or wall), i.e. additional bar and adjacent structure
Part (backbar or wall) effectively connects.Later period cast-in-place concrete at this, the sponson of additional bar make concrete prefabricated board
It is securely connect with last layer and adjacent members, effectively improves the globality and safety of assembled monolithic concrete structure.
This invention simplifies the constructions of traditional superimposed sheet, and it is overhanging (i.e. cancellation beard muscle) while pre- in concrete to cancel reinforcing bar
Groove is reserved at making sheet end, and (i.e. the integral strength of superimposed sheet is not by shadow with whole plate consistency of thickness for the concrete thickness at guarantee truss
Ring, and facilitate production and transport), after concrete prefabricated board lifting in place, additional bottom muscle and distribution steel are placed in groove
Muscle, then rear pouring concrete form last floor construction.
