Abstract
The utility model discloses a special ejector for a large steel formwork, which is used for disassembling the formworks at the two sides of a building wall body and has the characteristics of simple structure, low cost as well as convenient utilization. The special ejector which is arranged on the large steel formwork is used for disassembling the formworks at the two sides of the building wall body, and comprises a screw rod and a nut which are mutually matched by a thread. The nut is fixedly connected with the formworks, and a clamping head is arranged at one end of the screw rod far from the wall body. The rotation between the screw rod and the nut leads the screw rod to carry out axial displacement, so as to push the wall body to separate the formworks which are fixedly connected with the nut from the two sides of the wall body, thereby realizing the disassembling of the formworks. The special ejector for the large steel formwork only has the following two simple fittings: the screw rod and the nut; therefore, the structure is fairly simple, and the cost is low. When in disassembling, only by screwing one head of the screw rod, the axial displacement can be carried out, so as to realize ejection; therefore, the operation is fairly simple and convenient.
Description
Technical field
The utility model relates to a kind of building provision for disengagement, relates in particular to the special-purpose stripper of large steel moulding plate that a kind of template that is used to make the construction wall both sides breaks away from body of wall.
Background technology
In construction wall construction, generally be binding reinforcing bars is finished after in its both sides mounting template, again toward the interior concrete perfusion of template, treat concrete setting after, template disassembled just finished the blank wall.General dismounting template is with instruments such as crowbars template to be broken away from body of wall, and this method need expend more manpower, and the time is long, efficient is low, and unloading process is dangerous.The general dismounting mode of the highrise building or the repeatedly demoulding of the template of recycling is that hydraulic top pushing device is installed on template, after body of wall solidifies, after opening hydraulic means, rely on the driving of hydraulic cylinder that the template dismounting is broken away from body of wall, the method of this stripper plate need be installed very many hydraulic cylinders, has increased construction cost greatly, and has controlled a plurality of hydraulic cylinders simultaneously, control system and control procedure are all very complicated, make mistakes easily.
Summary of the invention
At the deficiencies in the prior art, the technical problems to be solved in the utility model provides the special-purpose stripper of a kind of large steel moulding plate simple, that construction wall two side templates are dismantled in low, easy to use being used to of cost.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of special-purpose stripper of large steel moulding plate that is installed on this template, be used to dismantle the template of construction wall both sides, the special-purpose stripper of this large steel moulding plate comprises screw mandrel and the nut that cooperatively interacts by screw thread, this nut is fixedlyed connected with described template, and described screw mandrel has clamping head away from an end of body of wall.
As the improvement of such scheme, described template has through hole, and described screw mandrel is arranged in this through hole.
As the improvement of such scheme, described nut has cylindrical bore, and the end that described screw mandrel is relative with described clamping head has socket cap, and this socket cap and described counterbore are suitable.
As the improvement of such scheme, described clamping head is cross head or interior hexagonal screw mandrel head or outside polygon screw mandrel head.
As the improvement of such scheme, described screw mandrel is vertical mutually with described template.
The beneficial effects of the utility model are: the special-purpose stripper of the disclosed a kind of large steel moulding plate of the utility model is by the rotation between threaded-fit screw rod and the nut, make screw mandrel produce axial displacement with respect to nut, thereby the pushing tow body of wall makes the template of fixedlying connected with nut peel off from the body of wall two sides, realizes the dismounting of template.The special-purpose stripper of this large steel moulding plate only needs two simple accessories: screw mandrel and nut, structure are very simple, and cost is also low, and one that only need twist screw mandrel in the time of dismounting just can make it produce the axial displacement realization demoulding, and its operation is very simple and convenient.
Description of drawings
Fig. 1 is the structural representation of the special-purpose stripper of the utility model large steel moulding plate.
The specific embodiment
Further specify the special-purpose stripper of the utility model large steel moulding plate below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of special-purpose stripper of large steel moulding plate that is installed on this template of the utility model, be used to dismantle the template 10 of construction wall both sides, the special-purpose stripper of this large steel moulding plate comprises screw mandrel 20 and the nut 30 that cooperatively interacts by screw thread, this nut 30 is fixedlyed connected with described template 10, and described screw mandrel 10 has away from an end of body of wall and is used for twisting the clamping head 22 that this screw mandrel 20 rotates screw mandrel 20.During use, twist clamping head 22 and make screw mandrel 20 rotations, since nut 30 fixing with template 10 on, generally be to be welded on the template 10, then screw mandrel 20 just can produce axial displacement with respect to nut 30, promptly can produce displacement to wall direction, therefore produce the power of pushing tow body of wall, order about template 10 and separate, template is peeled off from surface of wall, realized the dismounting of template 10 with body of wall.
More preferably, described template 10 has through hole, and described screw mandrel 20 is arranged in this through hole.The face that end face of screw mandrel 20 and the internal face of template 10 promptly contact with body of wall can guarantee that like this screw mandrel 20 can not embed body of wall and can not extract on one side, and it is raised or sunken to guarantee that simultaneously wall leveling does not have.
More preferably, described nut 30 has cylindrical bore 35, described screw mandrel 20 and described clamping head 22 relative ends promptly have socket cap 25 by an end of body of wall, this socket cap 25 be provided with counterbore 35 in and suitable with described counterbore 35, only keep very little gap between socket cap 25 and the counterbore 35, make and to rotate relatively between socket cap 25 and the counterbore 35, can avoid concrete to infiltrate in the gap again, destroy its mechanical performance.Wherein the socket cap shape can be the bulb shape, and both are suitable gets final product for screw mandrel head and counterbore 35.Socket cap 25 or screw mandrel head do not protrude the internal face of template 10, are difficult to extract in case embed body of wall, in its yet not whole recessed template, leave projection to prevent body of wall.
More preferably, described clamping head 22 is cross head or interior hexagonal screw mandrel head or outside polygon screw mandrel head.This clamping head 22 is used for twisting this position makes screw mandrel 20 produce rotation relatively, and this clamping head 22 can be selected different shapes owing to use the difference of aid, can be that hexagon socket head, hexagonal are first-class.
More preferably, described screw mandrel 20 is vertical mutually with described template 10, thereby makes screw mandrel 20 perpendicular to body of wall, makes the jacking force of screw mandrel 20 all act on the body of wall, has utilized this jacking force to greatest extent, makes that large steel moulding plate special use stripper is more durable, reliable.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
