Detailed Description
Example 1
As shown in fig. 1, the utility model provides a prefabricated wallboard door opening temporary reinforcement device, including buckle 4, bracing piece 2, adjusting collar 1 and fastener, the both ends of adjusting collar respectively with one end threaded connection of bracing piece 2, rotate between the other end of bracing piece 2 and the buckle 4 and be connected, be equipped with the through-hole on buckle 4's the at least side, wear to be equipped with the fastener on the through-hole, the cover is equipped with rather than threaded connection's solid fixed ring 6 on the fastener, gu fixed ring 6 welded fastening in buckle 4's the outside, buckle 4 can dismantle fixed connection through fastener and the prefabricated wallboard 10 of its adaptation. Specifically, the fastener passes its one end of through-hole and prefabricated wallboard 10 butt to through solid fixed ring 6 locking fastener, guarantee the connection structure intensity between buckle 4 and prefabricated wallboard 10.
Wherein the fixing ring 6 is a nut.
This embodiment will interim reinforcing apparatus place in door opening position, rotatory buckle 4 makes it be connected with prefabricated wallboard 10 cooperation, it makes buckle 4 press from both sides tight fixed prefabricated wallboard 10 to screw up the fastener, make and not produce relative displacement between buckle 4 and the prefabricated wallboard 10, again according to the width of door opening, adjust the relative counterpoint position between adjusting collar 1 and its both ends bracing piece 2, with the width phase-match of door opening, thereby form a whole between prefabricated wallboard 10 and the reinforcing apparatus that makes door opening both sides, realize the reinforcing effect to the door opening. Through adopting interim reinforcing apparatus, can make the prefabricated wallboard 10 of door entrance to a cave both sides have certain rigidity under reinforcing apparatus's effect, and then strengthen the overall structure intensity that has prefabricated wallboard 10 of door entrance to a cave, avoid having prefabricated wallboard 10 of door entrance to a cave to appear cracked phenomenon because the atress is uneven when the drawing of patterns lifts by crane. And embedded parts do not need to be reserved on the prefabricated wall panel 10, so that the cost is saved and the operation is convenient. Simple structure, convenient to detach, circulated use, and the door opening of different width all can satisfy the operation requirement through adjusting the relative position between adjusting sleeve 1 and the bracing piece 2.
Further, be equipped with rolling bearing 3 between the other end of bracing piece 2 and buckle 4, rolling bearing 3 includes bearing inner ring, bearing outer loop, keeps ware and ball to locate between bearing inner ring and the bearing outer loop, keep being equipped with a plurality of mounting grooves on the ware, the ball is located on the mounting groove, and bearing inner ring and bearing outer loop rotate relatively, can dismantle fixed connection between bearing inner ring and the bracing piece 2, and bearing outer loop and buckle 4 welded fastening are connected. The axis direction along bracing piece 2 rotates between buckle 4 and the bracing piece 2, according to the structure of door opening, makes its prefabricated wallboard 10 cooperation connection with door opening both sides through rotatory buckle 4, the installation of being convenient for.
Still further, the inner wall of the bearing inner ring is provided with a clamping groove, and the support rod 2 is provided with a clamping block which is connected with the support rod in an adaptive mode. The fixture block is inserted in the clamping groove, so that the support rod 2 is clamped with the bearing inner ring and is detachably fixed. During the in-service use, buckle 4's thickness is set for according to door opening wall plate thickness, according to the thickness of door opening, through changing buckle 4 rather than the difference that corresponds to it is fixed to realize buckle 4 and prefabricated wallboard 10's cooperation, dismouting simple structure, easily change. In addition, through being equipped with fixture block and draw-in groove, make bracing piece 2 and bearing inner ring have limiting displacement, prevent relative rotation between the two.
Furthermore, the periphery of the adjusting sleeve 1 is a smooth structure which gradually decreases towards two ends as the center. The structural design of the adjusting sleeve 1 increases the deformation resistance, improves the rigidity of the whole structure, and is convenient for an operator to hold and rotate.
Further, a gasket 7 is arranged between the fastener and the prefabricated wall panel 10. The gasket 7 prevents the fastener from directly contacting the prefabricated wall panel 10 during the process of reinforcing the prefabricated wall panel 10, and the fastener rotates to cause friction and abrasion, thereby protecting the prefabricated wall panel 10. The gasket 7 can be a steel gasket 7, during installation, the fastener sequentially penetrates through the fixing ring 6 and the through hole, the fastener is perpendicular to the plane of the buckle 4, the steel gasket 7 is welded at the end of the fastener, and the steel gasket 7 is parallel to the plane of the buckle 4. The gasket 7 can also be an elastic gasket 7, during installation, the fastener sequentially penetrates through the fixing ring 6 and the through hole, the fastener is perpendicular to the plane of the buckle 4, then the elastic gasket 7 is placed between the fastener and the prefabricated wallboard 10, and the elastic gasket 7 is parallel to the plane of the buckle 4. The elastic gasket 7 can strengthen the locking capability of the fastener, and ensure the connection structure between the buckle 4 and the prefabricated wall panel 10.
Furthermore, the outside of bracing piece 2 is equipped with the stop nut 9 with 1 tip butt of adjusting collar for the displacement between the relative adjusting collar 1 of restriction bracing piece 2 can strengthen the structural strength between bracing piece 2 and the adjusting collar 1 simultaneously, improves whole anti deformability.
Further, the fastener is a screw 5.
Example 2
The difference from embodiment 1 is that, as shown in fig. 2 and 3, a first connecting shaft 8 is further provided between the rotary bearing 3 and the support rod 2, one end of the first connecting shaft 8 is fixedly connected with the inner ring of the bearing by welding, and the other end of the first connecting shaft 8 is connected with the other end of the support rod 2 by screw thread.
Threaded connection between first connecting axle 8 and the bracing piece 2 can realize according to door opening wall plate thickness to change rather than the different buckle 4 that corresponds, thereby realize that buckle 4 is fixed with prefabricated wallboard 10's cooperation, dismouting simple structure, easily change.
The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
