The portion of the truss reinforcement 120 embedded inside the prefabricated panel 110 is a first portion 121, and the portion of the truss reinforcement 120 exposed from the surface of the prefabricated panel 110 is a second portion 122.
The number of the truss reinforcing bars 120 is plural. A plurality of truss rebars 120 are arranged in parallel and spaced apart. As shown in fig. 1, the number of the truss bars 120 is four in the present embodiment. The number of truss bars 120 may also be three, five, etc. in other numbers.
The reinforcing steel 130 is at least one. The reinforcing steel 130 is fixedly coupled to the prefabricated panel 110. The reinforcing steel 130 is located on the same side of the prefabricated panel 110 as the second portion 122 of the truss reinforcement 120. The reinforcing steel 130 extends in a direction perpendicular to the direction in which the truss reinforcing steel 120 extends.
Specifically, the reinforcing steel 130 may be fixedly coupled directly to the prefabricated panels 110. The reinforcing steel 130 may be fixedly coupled to the prefabricated panels 110 indirectly by being fixedly coupled to the truss reinforcement 120.
The reinforcing steel 130 is positioned on the same side of the prefabricated panels 110 as the second portions 122 of the truss reinforcing bars 120, and the reinforcing steel 130 and the second portions 122 of the truss reinforcing bars 120 can simultaneously support the prefabricated panels 110 when the prefabricated laminated floor members 100 are transported, hoisted or stacked.
Because the extending direction of the reinforcing steel 130 is perpendicular to the extending direction of the truss reinforcing steel 120, the reinforcing steel 130 can improve the rigidity of the prefabricated composite floor slab member 100 in the direction perpendicular to the truss reinforcing steel 120, and further can effectively prevent the prefabricated composite floor slab member 100 from cracking in the transportation, hoisting and stacking processes. After the prefabricated composite floor slab member 100 is transported, hoisted or stacked, the reinforcing steel 130 can be detached from the prefabricated composite floor slab member 100, so that the subsequent construction process is facilitated.
In an embodiment, the number of the reinforcing steel 130 may be multiple, and the plurality of reinforcing steel 130 are arranged in parallel and at intervals. The plurality of reinforcing steels 130 is advantageous in enhancing the rigidity of the prefabricated laminated floor structure 100 in the direction perpendicular to the truss reinforcing bars 120. Referring to fig. 1, in the present embodiment, the number of the reinforcing steel 130 is two. The number of the reinforcing steel members 130 may be three, four, or more.
In an embodiment, the reinforcing steel 130 is detachably connected to the prefabricated slab 110, so that after the prefabricated laminated floor slab 100 is transported, hoisted or stacked, the reinforcing steel 130 is conveniently detached from the prefabricated laminated floor slab 100, and further, the subsequent construction process is conveniently performed.
Specifically, the reinforcing steel 130 and the prefabricated slab 110 may be detachably connected by means of binding, which facilitates the connection and detachment of the reinforcing steel 130 and the prefabricated slab 110.
In one embodiment, the prefabricated laminated floor elements 100 further include connectors (not shown) embedded in the prefabricated panels 110 and exposed from the surfaces of the prefabricated panels 110. The reinforcing steel 130 is fixedly coupled to the exposed portion of the coupling member, so that the reinforcing steel 130 is indirectly fixedly coupled to the prefabricated panel 110, thereby facilitating the fixed coupling of the reinforcing steel 130 to the prefabricated panel 110.
The reinforcing steel 130 and the connecting member may be connected by means of a screw connection. Specifically, the connecting member may be a steel column, and the steel column is provided with a threaded hole, and the reinforced steel 130 is provided with a threaded hole corresponding to the threaded hole, and the threaded hole is respectively matched with the threaded hole on the steel column and the threaded hole on the reinforced steel 130 through a bolt, so as to fixedly connect the reinforced steel 130 to the connecting member.
Because the reinforcing steel 130 and the connecting member can be connected by means of screw threads, the reinforcing steel 130 and the connecting member can be conveniently detached, so that the reinforcing steel 130 can be conveniently detached from the prefabricated composite floor slab member 100.
In one embodiment, the reinforcing steel 130 is fixedly connected to the connecting member by means of banding.
Specifically, the connecting member may be a steel block or a steel plate, and the reinforcing steel 130 is fixedly connected to the portion of the connecting member exposed out of the prefabricated slab 110 by means of binding, so as to facilitate detachment, and thus the reinforcing steel 130 is conveniently detached from the prefabricated laminated floor slab 100.
In an embodiment, the reinforcing steel 130 is detachably connected to the truss reinforcing bars 120, and the reinforcing steel 130 is indirectly detachably connected to the prefabricated panels 110, so that the reinforcing steel 130 can be conveniently detached from the truss reinforcing bars 120 after the transportation, hoisting or stacking of the prefabricated laminated floor slab 100 is completed, thereby facilitating the subsequent construction process.
In one embodiment, the reinforcing steel 130 is a channel steel, an H-beam, or an i-beam.
In one embodiment, the reinforcing steel 130 is attached to the prefabricated panel 110. Specifically, as shown in fig. 2, in the present embodiment, the reinforcing steel 130 is a channel steel. The surfaces of the channel bars are attached to the prefabricated panels 110, so that the reinforcing steel 130 can more reliably support the prefabricated panels 110, which is advantageous in improving the rigidity of the prefabricated panels 110 in the direction perpendicular to the truss reinforcing steel 120.
In one embodiment, each reinforcing steel 130 includes a plurality of lengths of sequentially spliced rebar members (not shown). Adjacent rebar members are detachably connected.
Specifically, the number of the reinforcing steel members may be two, three, four, etc., and the specific number may be specifically set according to the specification of the prefabricated panel 110. The adjacent steel bar components are connected in a binding mode or in a threaded connection mode, so that the connection and the disassembly are convenient.
Since the reinforcing steel 130 includes a plurality of reinforcing bar members, a portion of the reinforcing bar members may be selected for splicing. Because adjacent steel bar component can dismantle the connection, when having used up to consolidate steel 130, can dismantle the steel bar component each other, conveniently deposit, when needs use and consolidate steel 130, can select the steel bar component of a certain amount to splice. The reinforcing steel members with different numbers can be spliced into the reinforcing steel 130 with different lengths, so that the prefabricated plates 110 with different specifications can be suitable, and the reinforcing steel 130 does not need to be customized for the prefabricated plates 110 with different specifications, thereby saving the reinforcing steel material.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
