Description
Technical field
This utility model relates to a kind of architectural prefab, the rear-mounted connecting elements being specifically related between a kind of architectural prefab.
Background technology
Traditional cast-in-place concrete building structure, needs to build pouring of substantial amounts of construction steel frame and safety guard net, concrete wall and floor and also needs to substantial amounts of forming panel.Concrete material needs site setup mixing plant or by vehicle transport to on-the-spot, if site setup mixing plant, equipment investment is big, and a project also needs after completing to transport equipment Removal, there is the possibility damaged in equipment during removing transhipment, and on the other hand cost of wheeling is the most of a relatively high.Vehicle transport on the one hand cost is high, on the other hand there is also certain waste.
The cast in situs of concrete is also required to relatively large equipment, because casting process must be continuous print, in addition it is also necessary to field personnel's continuous duty in evening on daytime, the especially operator on duty in evening are easily tired and fall asleep, pouring quality is possible to go wrong, and consequence is the most serious.
Additionally the concrete cast in situs of body of wall and floor is required for certain curing period after completing, and causes the prolongation in construction cycle, labor intensive material resources.
Input cost and the cost of wheeling of forming panel are the highest, and additionally erection and the dismounting of forming panel not only needs substantial amounts of manpower, there is also potential safety hazard.
So occurring in that the mode of production of full prefabricated panel and floor at present, by first prefabricated by design requirement in factory to wallboard and floor, on-the-spot need to connect using connecting elements between prefabricated wallboard, between wallboard and floor, thus overcome aforementioned poured in place concrete forming wall plate and the defect of floor.
Utility model content
When the purpose of this utility model is to provide one to make prefabricated component pour, embedded part structure is simple, attended operation simple rear-mounted connecting elements when moulding prefabricated part connects.
The utility model discloses the rear-mounted connecting elements between a kind of architectural prefab, cuboid box body and the connection securing member being vertically connected in cuboid box body pair of side plates including open top, the bottom surface of cuboid box body is across the reserved mounting groove position of two prefabricated components, and the securing member built-in connection respectively with corresponding prefabricated component that connects of both sides is connected fastening.
As preferably, the corresponding position of described cuboid box body pair of side plates offers circular hole and U-shaped hole respectively, and the opening in U-shaped hole is located therein the upper surface of side plate, and described connection securing member connects in circular hole and U-shaped hole respectively.
As preferably, described connection securing member is bolt, nut and gasket assembly, the body of rod of bolt through after the corresponding mounting hole on rectangular box with corresponding side prefabricated component mounting groove at built-in connection be connected as a single entity.
Slotted hole is offered in the another pair of side plates of described cuboid box body.
Rectangular opening is offered on the base plate of described cuboid box body.
Described cuboid box body connects the structure that also can take circular hole and the slotted hole offering concentrically line respectively in the pair of side plates of described connection securing member, and the length direction of slotted hole is along the short transverse of this side plate.The alternative U-shaped hole of slotted hole, regulates the site error between the built-in fitting of two prefabricated components.
Described cuboid box body is metal case, to ensure good stress performance.
This utility model bridges the mounting groove of two prefabricated components by a cuboid box body, is connected fastening by being connected to the securing member that connects of box body one opposite side with the built-in connection of corresponding prefabricated component, and simple to operate, stress performance is good.
In order to make attended operation simple further, the opposite side at cuboid box body offers circular hole and U-shaped hole respectively.During because prefabricated component pours, on two prefabricated components may there is certain error in the pre-buried position of built-in fitting, and this error just can be regulated by U-shaped hole.Certain U-shaped hole can also substitute with slotted hole.
Because after the built-in fitting of whole rear-mounted connecting elements and prefabricated component connects, need to use self-compacting concrete its filling to be processed, finally do not see link position from the appearance of prefabricated component.
In order to make more preferably to form an entirety at mounting groove reserved on cuboid box body and prefabricated component, in the bottom surface of cuboid box body with do not connect an opposite side of securing member and offer slotted hole and rectangular opening respectively, when so filling processes, the concrete inside and outside box body forms entirety, can improve the holistic resistant behavior of junction.

Detailed description of the invention
As shown in Figures 1 to 4, present embodiment discloses the rear-mounted connecting elements between a kind of architectural prefab, the connection being primarily adapted for use between prefabricated panel.
This connecting elements includes cuboid box body 1, connecting bolt 2 and pad 3.
Cuboid box body 1 is metal case, and its top side is open side, and the corresponding position of one opposite side offers circular hole and U-shaped hole respectively, and the opening in U-shaped hole is located therein the upper surface of side plate.
Offer in the another pair of side plates of cuboid box body 1 and on slotted hole 11, base plate, offer rectangular opening 12.
During prefabricated panel, reserve mounting groove in the corresponding position of wall-plate level direction side, built-in fitting threaded steel pipe is set at mounting groove.
After prefabricated panel scene erects, the seam crossing between two adjacent prefabricated panels is connected as a single entity with corresponding pre-buried corrugated tubing by this connecting elements.During connection, the bottom surface of cuboid box body is placed across two mounting grooves, make to offer simultaneously the opposite side in circular hole and U-shaped hole respectively with corresponding pre-buried corrugated tubing centering, then realize connecting fastening by bolt and pad.As shown in Figure 4.
The installing hole connecting securing member in cuboid box body 1 pair of side plates also can use circular hole and the structure of slotted hole pairing, say, that U-shaped hole can substitute with slotted hole.
The present embodiment bridges the mounting groove of two prefabricated components by a cuboid box body, is connected fastening by being connected to the securing member that connects of box body one opposite side with the built-in connection of corresponding prefabricated component, and simple to operate, stress performance is good.
In order to make attended operation simple further, the opposite side at cuboid box body offers circular hole and U-shaped hole respectively.During because prefabricated component pours, on two prefabricated components may there is certain error in the pre-buried position of built-in fitting corrugated tubing, and this error just can be regulated by U-shaped hole.Certain U-shaped hole can also substitute with slotted hole.
Because after the built-in fitting of whole rear-mounted connecting elements and prefabricated component connects, need to use self-compacting concrete its filling to be processed, finally do not see link position from the appearance of prefabricated component.
In order to make more preferably to form an entirety at mounting groove reserved on cuboid box body and prefabricated component, in the bottom surface of cuboid box body with do not connect an opposite side of securing member and offer slotted hole and rectangular opening respectively, so concrete inside and outside filling handling duration cube shape box body forms entirety, can improve the holistic resistant behavior of junction.
