The utility model discloses connect the fastener and have simple structure, make easy, with low costs, hookup fast, simple to operate, need specialized tool, material saving, hookup intensity are big, the hookup steady quality, can provide advantage such as hookup prestressing force.
Description
Technical field
The utility model belongs to building operations accessory technical field, specifically a kind of connection fastener of cement steel prefabricated component.
Background technology
Along with the needs of the raising of China's skill resources costs and social development high-quality and high speed, in traffic and building constructions industry, building unit prefabricated more and more general, traditional traffic and building constructions industry will enter the New Times of factorial praluction.
The specific product of builing industry batch production is embodied in using reinforcing bar and cement on the prefabricated component of main material.Prefabricated component has many benefits in process of factory production.But neither be abandoned, prefabricated component is in lifting and transportation, and its size and weight are all restricted, as highway transportation requires that each solid memder width can not more than 2.2 meters, substance maximum Lifting Capacity that can not exceed hanging device etc., in actual design and manufacturing process.Many large components are all designed to many primary structural components in plant produced.Large component is assembled into after transporting to building site.
For ensureing the requirement of the rear large member designs intensity of assembling, in practice of construction, usually require that the reinforcing bar between each primary structural component will closely couple together, and require that junction intensity is not second to being connected reinforced steel bar strength, between component, the quality of bar connecting directly has influence on the quality of the rear product of assembling, determines the success or failure of engineering.
At present between precast reinforced concrete part the connection of reinforcing bar conventional have the following two kinds mode:
1, weld, divide again butt welding and joint welding two kinds, welding manner is simple and clear, and cost is not high, but site construction labour intensity is large, and quality relies on the technical level of welder, stable not.
2, overlap colligation, the labor strength of this mode is little, and technical requirements is not high, but bar splicing distance will reach more than 60D, wastes a large amount of reinforcing bar, and the cast-in-place amount of cement concrete is large.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of easy construction, structure simple, be easy to the bar connecting fastener that manufactures, with low cost, quality of connection is reliable, stable.
The utility model solves the problems of the technologies described above with following technical scheme:
The connection fastener of the utility model cement steel prefabricated component, it comprises shaped as frame junction button, and the both sides of shaped as frame junction button are respectively equipped with the through hole supplying the connecting reinforcement of cement steel bar preassembling product to pass, and connecting reinforcement and shaped as frame junction button are formed and be fastenedly connected.
One side through hole of described shaped as frame junction button is unthreaded hole, and is furnished with packing ring and nut, and the through hole of opposite side is screwed hole.
Two side through hole of described shaped as frame junction button are unthreaded hole, and wherein side unthreaded hole is furnished with packing ring and nut, and the nut that is positioned at shaped as frame junction button is welded in the side of opposite side unthreaded hole.
The connection fastener of the utility model cement steel prefabricated component, described shaped as frame junction button bends to enclosing square shape by band steel, and the two ends of band steel are fixedly connected by welding.
The utility model fastener is adopted to connect cement steel prefabricated component, compared with traditional connecting mode, have that structure is simple, easy to manufacture, cost is low, can connect fast, easy for installation, do not need special tool, save material, linking intensity is large, connect steady quality, can provide advantages such as connecting prestressing force.
Accompanying drawing explanation
Fig. 1 is the structural representation of the connection fastener of the utility model cement steel prefabricated component.
Detailed description of the invention
As shown in Figure 1, the connection fastener of the utility model cement steel prefabricated component comprises shaped as frame junction button 5, the left and right sides of shaped as frame junction button 5 is respectively equipped with through hole, the connecting reinforcement 2 that left side cement steel prefabricated component 1 stretches out and the connecting reinforcement 7 that right side cement steel prefabricated component 8 stretches out respectively car have symmetrically arranged external screw thread, connecting reinforcement 2 and connecting reinforcement 7 are fastenedly connected by the left side nut 4 and right side nut 6 that are positioned at shaped as frame junction button symmetry through after two side through hole of shaped as frame junction button 5, between left side nut 4 and PATENT left side via, packing ring 3 is housed, right side nut 6 is welded on the side of right side through hole, and be positioned at shaped as frame junction button 5.
During use, first the PATENT left side via of shaped as frame junction button 5 is enclosed within the connecting reinforcement 2 in left side, then packing ring 3 is loaded onto, load onto nut 4 subsequently, executing turn nut 4 makes left side reinforcing bar protrude nut 4 end face, at this moment again the right side through hole of shaped as frame junction button 5 is loaded onto the connecting reinforcement 7 on right side by nut 6, rotate shaped as frame junction button 5, nut 6 can make shaped as frame junction button 5 move to the right, after shaped as frame junction button 5 is eliminated with the diastema of packing ring 3, shaped as frame junction button 5 can drive the packing ring in left side to rotate together with nut, because the screw thread on the reinforcing bar that shaped as frame junction button about 5 two ends are to be coupled is reverse, shaped as frame junction button 5 is forced to be moved to the left to making the nut 4 in left side, right side nut 6 forces shaped as frame junction button 5 to move right, result shaped as frame junction button 5 is strained by the reinforcing bar of both sides, thus reach the effect of connection.
The utility model also can adopt alternate manner the connecting reinforcement of cement steel prefabricated component and shaped as frame junction button to be formed and be fastenedly connected, and such as, is screwed hole, can be formed directly in the right side via design of shaped as frame junction button be threaded with connecting reinforcement.When using the utility model to connect cement steel prefabricated component, when shaped as frame junction button is rotated, the nut at two ends, left and right is under the effect of reverse thread, shaped as frame junction button is forced to move to the other side, finally make the reinforcing bar at shaped as frame junction button and two ends closely link together, and certain connection prestressing force can be provided.
The connecting reinforcement of cement steel prefabricated component and shaped as frame junction button are formed after being fastenedly connected, then by fluid concrete, the space between cement steel prefabricated component is filled up full.
Shaped as frame junction button described in the utility model bends to enclosing square shape by band steel, and the two ends of band steel are fixedly connected by welding.
