Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
As shown in Figure 1, it is a kind of structural schematic diagram of assembly concrete floor construction.
A kind of assembly concrete floor construction of the invention includes panel 1, and panel 1 includes exterior trim surface layer 11 and bottom
12, insulating layer 2 and concrete layer 3 are disposed between exterior trim surface layer 11 and bottom 12；It is protected by being arranged in floor construction
Warm layer 2 and exterior trim surface layer 11, to meet the requirement to heat preservation and inner wall surface in the regions such as workshop.
As shown in Fig. 2, being provided with keel 4 in concrete layer 3, keel 4 include several longitudinal bracing keel being parallel to each other
41, longitudinal bracing keel 41 mainly play load-bearing effect；It is connected between longitudinal bracing keel 41 by lateral keel 43, lateral keel 43
Including laterally accepting keel 431 and located lateral keel 42, the both ends for laterally accepting keel 431 are respectively arranged with the first connector sleeve
421 and second connector sleeve 422, as shown in Figure 4.
Specifically, the first connector sleeve 421 and 41 clearance fit of longitudinal bracing keel, laterally seismic wave and inhaled with playing buffering
Receive the effect of lateral seismic energy；Second connector sleeve 422 is fitted close with longitudinal bracing keel 41, same longitudinal bracing keel 41
On the first connector sleeve 421 mutually abutted with the second connector sleeve 422；The position for laterally accepting keel 431 is limited with playing
Fixed effect.
First connector sleeve 421 includes the identical lantern ring of upper and lower two structures, and the spacing between two lantern rings is connect with second
Set 422 it is of same size；Cooperated by the first connector sleeve 421 and the second connector sleeve 422, so as to play buffering earthquake simultaneously
With the effect for reinforcing keel.
One end of located lateral keel 431 is connect with longitudinal bracing keel 41, and the other end is located at 3 lateral edge of concrete layer
At adjacent position, to be connect with the located lateral keel 431 on adjacent floor, to realize connection and positioning function.
Keel 4 and 3 edge joins of concrete layer are provided with connecting plate；3 edge of concrete layer and 4 interconnecting piece of keel offer holding groove
41, by the way that holding groove 41 is arranged, positioned with facilitating to be directed at connecting plate 45.
It is provided with built-in fitting 5 at opposite position in bottom 12 and insulating layer 2, as shown in figure 5, built-in fitting 5 includes setting
Locating piece 51 in bottom 12 and insulating layer 2, locating piece 51 can be sheet or plate structure, to be preferably fixed on bottom
In layer 12 and insulating layer 2.
Locating piece 51 is located at neighbouring 1 corner positions of panel, is connected with each other between locating piece 51 by balancing pole 52, locating piece
It is connected with each other between 51 and balancing pole 52 by hinged shaft；Balancing pole 52 passes through auxiliary connection 44 phase of reinforcing bar with longitudinal bracing keel 41
Even, the end of auxiliary connection reinforcing bar 44 is socket-connected by fixing sleeve 53 with balancing pole 52；Auxiliary connection reinforcing bar 44 and fixing sleeve 53
Between be provided with reinforcing rib 54.
By the way that locating piece 51 is arranged in neighbouring 1 corner positions of panel, the building as caused by seismic wave can be effectively prevent
Plate edge dislocation splits, so that overall structure be caused to destroy；By the way that balancing pole 52 is arranged, and by balancing pole 52 and 53 sets of fixing sleeve
It connects, so that micro-displacement can occur for balancing pole 52 and fixing sleeve 53, in earthquake with earthquake energy；
It is connect by auxiliary connection reinforcing bar 44 with fixing sleeve 53, relative to keel 4, load-bearing pressure is lower, and toughness is stronger, tool
There is better recovery capability；By setting the connection type between balancing pole 52 and locating piece 51 to hingedly, year can equally be played
The effect of earthquake energy.
Here is the construction method provided by the invention using above-mentioned assembly concrete floor construction comprising following step
It is rapid:
S1, lateral keel 43 and longitudinal bracing keel 41 are socket-connected, and is moved to setting position.
Specifically, first laterally accepting keel 431, the first connector sleeve 421 of located lateral keel 42 and the second company for several
Female connector 422 is mutually aligned, and is located at the second connector sleeve 422 between two lantern rings of the first connector sleeve 421, then again by longitudinal branch
It supports keel 41 to be inserted into the first connector sleeve 421 and the second connector sleeve 422, after lateral keel 43 is moved to setting position, in cross
To the end welded connecting plate 45 of positioning keel 42 and longitudinal bracing keel 41, so as to being mutually butted between floor.
S2, the welding auxiliary connection reinforcing bar 44 on the longitudinal bracing keel 41 of two sides, and pacify on auxiliary connection reinforcing bar 44
Balancing pole 52 is filled, locating piece 51 is installed at 52 both ends of balancing pole.
Specifically, structure is thicker since longitudinal bracing keel 41 play load-bearing effect, therefore auxiliary connection reinforcing bar 44 is welded
It connects on longitudinal bracing keel 41, can guarantee the reliability connecting with balancing pole 52.
Set 53 and reinforcing rib 54 is welded and fixed in the end of auxiliary connection reinforcing bar 44 first, is then socketed in balancing pole 52
On fixing sleeve 53, it is fitted close balancing pole 52 and fixing sleeve 53；Then it is installed and is positioned by hinged shaft at the both ends of balancing pole 52
Part 51.
S3, by concreting into mould vehicle and the keel 4 for having built-in fitting are inserted into, by set temperature and time
It rests, forms the green body with concrete layer 3, after so that green body is reached setting hardness, mold and green body are hung to by reversal hanger and cut
It is framed to be hung on mould carriage on cutting mill, it is then hung to mould vehicle upper group mould, is poured next time.
Then casting concrete layer 3 first gradually pours insulating layer 2, bottom 12 and exterior trim surface layer 11.
S4, it rests after pouring into quiet room of stopping；Reach and go out quiet room of stopping after pulling out pricker hardness and carry out pulling out pricker, and overturns demoulding
It is cut, 4 position of keel is marked on green body after dicing, then opens up holding groove 31.
Holding groove 31 is primarily to facilitate the position of observation and the plate 45 that is located by connecting, preferably to connect each floor.
S6, the longitudinal bracing keel 41 of floor opposing upper and lower are connected with each other during installation, by the opposite floor in left and right
Lateral keel 43 be connected with each other；Then blind is poured by design requirement, completes the assembly construction of floor construction.
Specifically, connecting plate 45 is then welded on one as shown in figure 3, correspond to each other each component by connecting plate 45
It rises, so that the basic assembly of floor is completed, then as needed, casting concrete or other materials at floor connecting sewing, i.e.,
The assembly of achievable floor construction is constructed.
A specific embodiment of the invention is described above, in order to facilitate understanding by those skilled in the art this hair
It is bright, it should be apparent that the present invention is not limited to the ranges of specific embodiment, for those skilled in the art,
As long as various change is in the spirit and scope of the present invention that the attached claims limit and determine, these variations are aobvious and easy
See, all are using the innovation and creation of present inventive concept in the column of protection.
