Description
Technical field
The utility model relates to the technical fields of superimposed sheet making apparatus, more particularly, to a kind of for pouring superimposed sheet
Formwork erecting structure.
Background technique
Superimposed sheet is the building slab that a kind of mode that prefabricated and cast-in-place concrete combines produces at present, prefabricated board and its
Upper cast-in-place concrete layer is integrated into a whole superimposed sheet, and the main reinforcement of prefabricated board is the main reinforcement of superimposed sheet, the cast-in-place coagulation in top
Soil layer only configures negative reinforcement and distributing bar, and prefabricated board is used as the bed die of cast-in-place concrete layer, it is not necessary to be cast-in-place concrete
Layer support shuttering, prefabricated board bottom surface is smooth, and the ceiling (i.e. the bottom surface of superimposed sheet) of lower floor can no longer paint plastering；This
Kind of superimposed sheet has the globality of cast-in-situ reinforced concrete slab, while it is big with rigidity, crack resistance is good, does not increase reinforcing bar disappears
Consumption saves template, shortens the advantages that duration of entire engineering.
In existing, a kind of formwork erecting structure, referring to Fig.1, including the casting space 1 being made of four blocks of side plates 2 and ground, relatively
Two blocks of side plates 2 on offer corresponding open slot, open slot upper end is connected to 2 upper end of side plate and along 2 length side of side plate
To offering several groups；When making superimposed sheet, after first reinforcing bar is put into open slot from open slot upper end, then it is slotting by inserted block 4
It is connected in open slot, wherein the two sides of inserted block 4, which are offered, offers through slot 11 along its short transverse, makes its 4 cross section of inserted block be in
It is I-shaped, it is plugged on side plate 2 using the through slot 11 on inserted block 4, so that its inserted block 4 is closed open slot, avoid casting concrete mistake
Cheng Zhong, the concrete in casting space 1 are flowed out from open slot.
When prior art among the above has the following deficiencies: that one side is plugged on side plate 2 due to inserted block 4, inserted block 4
Inside protrudes from 2 inner wall of side plate, and the superimposed sheet outer wall for causing it to pour out is uneven, influences its globality；On the other hand, by
It is subjected to larger pressure in superimposed sheet, therefore the reinforcing bar being arranged in general superimposed sheet can be relatively more, thus the open slot pair on side plate 2
It should increase, one piece of one piece of inserted block 4 need to be successively plugged in open slot by staff, and operation is relatively complicated, influence its work effect
Rate.

Body.
In the present embodiment, the upper end that above-mentioned limited block 71 is in the side of slot 6 is opened up as inclined-plane 1,4 grafting of inserted block
In the process, lower end and 71 inclined-plane of limited block are driven.
Referring to Fig. 2, in the present embodiment, it is further fixed on handle 10 on the outside of upper plate 21, upper plate 21 is carried out convenient for staff
It picks and places.
The implementation principle of the present embodiment are as follows: first lower plate 22 is fixed on ground, then reinforcing bar is sequentially placed in lower plate 22
Half slot in, and then by upper plate 21 under the positioning action of locating piece 9, be installed in lower plate 22, and upper plate 21 from up to
Under be installed on lower plate 22 during, the correspondence of inserted block 4 is plugged in socket 5, and inserted block 4 and limited block 71 play inclined-plane transmission, is driven
Move forward and backward limited block 71 72 along the chute, when fixing groove 73 is connected to sliding slot 72, bullet of the limited block 71 in compressed spring 74
Property effect under, be plugged in fixing groove 73, position-limiting action played to inserted block 4, make that its upper plate 21 is stable to be installed in lower plate 22,
Again towards casting concrete in casting space 1, after concrete is dry, pull rod 75 is driven by connecting rod 8, limited block 71 is driven to solve
Except the position-limiting action to inserted block 4, then by handle 10, drives upper plate 21 and lower plate 22 to be detached from, releases the limit work to coil of strip,
Convenient for the taking-up work of superimposed sheet.
Embodiment 2: difference from example 1 is that, referring to Fig. 5, above-mentioned spring is set as extension spring 76, drives
Bar uses fastening bolt 77, and 76 both ends of extension spring are fixed with limited block 71 with respect to 6 side of slot and 72 inner wall of sliding slot respectively,
Under original state, limited block 71 is driven to be hidden in sliding slot 72 completely；The spiral shell being threadedly coupled with fastening bolt 77 is offered on socket 5
The side of pit, fastening bolt 77 is abutted with the side that limited block 71 is in sliding slot 72, in 77 rotation process of fastening bolt, is given
71 jacking force of limited block, drives limited block 71 to be plugged in the fixing groove 73 of inserted block 4.
In the present embodiment, the lower end that limited block 71 is in 73 side of fixing groove is set as inclined-plane 2 79, and limited block 71 is displaced
In the process, inclined-plane 2 79 and 73 bottom wall inclined-plane of fixing groove are driven, and drive the displacement force downward of upper plate 21.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
