Abstract
The utility model discloses a U-shaped precast slab assembly structure in the field of building parts. The U-shaped precast slab assembly structure comprises two steel channels with notches arranged oppositely, wherein the upper sides and the lower sides of the steel channels push against two adjacent precast slabs; through holes are formed in the two steel channels; a U-shaped bolt penetrates through the through holes; screws and nuts of the U-shaped bolt are matched for use; corners of the U-shaped bolt push against the back surface of the steel channel; at least one group of U-shaped bolts are arranged on one steel channel; and a pitch of each screw thread section does not exceed a screw lead by three times.The screws of the U-shaped bolt penetrate through a gap between the two precast slab, the nuts are tightened to clamp the steel channels to fix positions of the adjacent precast slabs, level splicing of the precast slabs is prevented, the time of tightening multiple nuts is shortened since the U-shaped bolt is adopted, the operation efficiency is improved, and the construction period of a whole project is shortened.
Description
Technical field
The utility model belongs to building fittings field, is specifically related to U-shaped precast plate splicing structure.
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.
But reality is, in the time building building with precast concrete plank, inevitably can not complete matching between adjacent precast concrete plank.If each precast concrete plank all can not complete matching, certainly will bring greatly potential safety hazard to building.
Utility model content
The technical problems to be solved in the utility model is to provide the U-shaped precast plate splicing structure that a kind of operating efficiency is high.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: U-shaped precast plate splicing structure, comprise the channel-section steel of two notch positioned opposite, and the upper of channel-section steel offsets with adjacent two precast plates respectively below; Two channel-section steels are provided with through hole, are interspersed with U-bolt on through hole, and screw rod and the nut of U-bolt are used in conjunction with, and the corner of U-bolt and the back side of channel-section steel offset; On one joint channel-section steel, be at least provided with one group of U-bolt, the pitch of thread segment is no more than three times of leads.
In technique scheme, the upper of two channel-section steels that notch is relative offsets with adjacent two precast plates respectively below, the space of the screw rod of U-bolt through two precast plates, fastening nut clamps the position of the fixing contiguous prefabricated plate of channel-section steel, prevent that precast plate splicing is smooth, adopting U-bolt is the time of twisting multiple nuts in order to reduce, and improves operating efficiency, shortens the construction period of whole engineering; It is for few nutting number of turns in the process of fastening nut that the pitch of thread segment is no more than three times of leads, has also improved operating efficiency; It is the chucking power equilibrium in order to ensure channel-section steel that head and the tail arrange threaded rod.
As the further optimization of technique scheme, consider the equilibrium that the channel-section steel back side is stressed, U-bolt nut segment is provided with packing ring.
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 splicing structure of the utility model embodiment.
Detailed description of the invention
As shown in Figure 1, U-shaped precast plate splicing structure, comprises the channel-section steel 1 of two notch positioned opposite, and upper following 3,4 of channel-section steel 1 offsets with adjacent two precast plates respectively; Two channel-section steels 1 are provided with through hole, are interspersed with U-bolt 2 on through hole, and screw rod and the nut of U-bolt 2 are used in conjunction with, and the back side of the corner of U-bolt 2 and channel-section steel 1 offsets; On one joint channel-section steel 1, be at least provided with one group of U-bolt 2, the pitch of thread segment is no more than three times of leads, and U-bolt 2 nut segment are provided with packing ring.
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 splicing structure, comprise the channel-section steel of two notch positioned opposite, the upper of channel-section steel offsets with adjacent two precast plates respectively below, it is characterized in that: described two channel-section steels are provided with through hole, on through hole, be interspersed with U-bolt, screw rod and the nut of U-bolt are used in conjunction with, and the corner of U-bolt and the back side of channel-section steel offset; On one joint channel-section steel, be at least provided with one group of U-bolt, the pitch of thread segment is no more than three times of leads.
