Abstract
The utility model discloses a U-shaped precast slab connecting member in the field of building members. The U-shaped precast slab connecting member comprises a U-shaped bolt penetrating into embedded part through holes of adjacent precast slabs respectively, and a tight nut fastened onto the U-shaped bolt, wherein a connecting sheet is connected between two screws of the U-shaped bolt; each thread pitch of the screws of the U-shaped bolt does not exceed two screw leads; a washer is arranged between the connecting sheet and the tight nut; an opening is formed in the connecting sheet connected with one screw of the U-shaped bolt; and the width of the opening is matched with the diameter of the screw.The adjacent precast slabs are connected together by the matching of the U-shaped bolt and the connecting sheet, the connecting sheet ensures smoothness and tightness between the adjacent precast slabs, the screws of the U-shaped bolt provide fastening support points for the connecting sheet, the opening in the connecting sheet allows quick mounting of the connecting member, and the mounting efficiency of the connecting member is improved.
Description
Technical field
The utility model belongs to building unit field, is specifically related to U-shaped precast plate connecting elements.
Background technology
The plate of making by Reinforced Concrete Materials, is basic structure or the member in building construction and various engineering structures, is commonly used for roof system, superstructure, platform, wall, retaining wall, basis, terrace, road surface, pond etc., and range of application is extremely wide.Armored concrete slab, by the flat shape side of being divided into plate, plectane and sketch plate, is divided into one-way slabs and two-way slab by the stressed mode of action of structure.The modal two-way slab without beams that has one-way slabs, supported along four sides two-way slab and supported by post.
Concrete slab has cast-in-place and prefabricated two kinds.Cast in place concrete plate conventionally and reinforced concrete beam be linked to be entirety and form the continuous form of structure of multispan, owing to being on-the-spot global formation, so good integrity, for having pipeline to pass or flooring in irregular shape is still well suited for, but its operation is many, wet trade is many, on-the-spot pouring, and construction period is longer.In order to improve efficiency of construction, in the roof system and superstructure of industry and civilian construction, precast concrete plank is but widely used, and conventional precast concrete plank has solid plate, hollowcore slab and trough slab, and the width of plate is depending on the actual conditions of local manufacture, lifting and haulage device.
In the time building building with precast concrete plank, often adopt the concavo-convex position between adjacent precast concrete plank to carry out chimeric connection, but this connection is because shakiness is by firmly, easily produces potential safety hazard.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of U-shaped precast plate connecting elements of quick locking.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: U-shaped precast plate connecting elements, comprise the U-bolt interting respectively in contiguous prefabricated plate built-in fitting through hole, and be fastened on the clamp nut on U-bolt; Between the two screw rods of U-bolt, be connected with brace, U-bolt screw flight tooth pitch is no more than two leads; Between brace and clamp nut, be provided with packing ring, the brace place that connects one of them screw rod of U-bolt is provided with opening, and the width of opening mates with the diameter of screw rod.
Technique scheme is used in conjunction with by U-bolt and brace, and contiguous prefabricated plate is linked together, and brace has ensured planarization and the tightness between contiguous prefabricated plate, and the screw rod of U-bolt provides fastening fulcrum for brace; Opening on brace makes the connecting elements when mounted can Fast Installation, has improved the installation effectiveness of connecting elements.
As the further optimization of technique scheme, consider the compliance of brace, the two ends that brace runs through U-bolt screw rod are all provided with opening, and the width of opening mates with the diameter of screw rod.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structure diagram of the U-shaped precast plate connecting elements of the utility model embodiment.
Detailed description of the invention
As shown in Figure 1, U-shaped precast plate connecting elements, comprises the U-bolt 4 interting respectively in contiguous prefabricated plate 1,2 built-in fitting through holes, is fastened on the clamp nut (not shown) on U-bolt 4; Between the two screw rods of U-bolt 4, be connected with brace 3, U-bolt 4 screw flight tooth pitch are no more than two leads; Between brace 3 and clamp nut, be provided with packing ring (not shown), the two ends that brace 3 runs through U-bolt 4 screw rods are all provided with opening 5, and the width of opening 5 mates with the diameter of screw rod.
Above-described is only preferred embodiment of the present utility model, should be understood that for a person skilled in the art, not departing under the prerequisite of the utility model structure, can also make some distortion and improvement, these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
1.U type precast plate connecting elements, comprise the U-bolt interting respectively in contiguous prefabricated plate built-in fitting through hole, be fastened on the clamp nut on U-bolt, it is characterized in that: between the two screw rods of described U-bolt, be connected with brace, U-bolt screw flight tooth pitch is no more than two leads; Between brace and clamp nut, be provided with packing ring, the brace place that connects one of them screw rod of U-bolt is provided with opening, and the width of opening mates with the diameter of screw rod.
