Abstract
The utility model discloses an abutting joint and assembly member for a precast slab in the field of building members. The abutting joint and assembly member for the precast slab comprises two steel channels whose notches are oppositely distributed, the upper and lower edges of the steel channel are respectively abutted against adjacent two precast slabs, rectangular through holes are formed in each of the two steel channels, a tensioning piece made of a rectangular steel bar is inserted into the rectangular through holes, a check block is arranged at one end of the tensioning piece, teeth are arranged at the other end of the tensioning piece at equal intervals and are matched in use with a tensioning block, the tensioning block is provided with a locking mechanism, the thickness of the tensioning piece is not more than 1.5cm, and the width of the tensioning piece is not more than 5cm. According to the abutting joint and assembly member for the precast slab, a commonly used thread counter piece is changed for a structure of the rectangular steel bar, and the thickness and the width of the rectangular steel bar are optimized, so that a gap between the adjacent abutted precast slabs is the smallest, and meanwhile, the transition displacement difference between the adjacent precast slabs is also smaller, and the subsequent loading level of the concrete is reduced.
Description
Technical field
The utility model belongs to building unit field, is specifically related to precast plate docking assembling members.
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 precast plate docking assembling members that a kind of precast plate butt seam is little.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: precast plate docks assembling members, comprises 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 rectangular through-hole, are interspersed with the tension part that rectangle steel bar is made in rectangular through-hole, and one end of tension part is provided with block, and the teeth that the other end is provided with equidistant setting are used in conjunction with tension piece; Tension piece is provided with retaining mechanism; The thickness of tension part is no more than 1.5cm, and width is no more than 5cm.
Technique scheme changes to conventional screw thread the structure of rectangle steel bar to draw piece, and thickness and the width of rectangle steel bar are optimized, make the gap minimum between the precast plate of adjacent docking, also make the transition displacement difference between adjacent precast plate less, reduce follow-up concrete loading simultaneously.
As the further optimization of technique scheme, for the back side of channel-section steel can be subject to uniform load, the two ends that tension part is pressed close to the channel-section steel back side have additional pad.
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 utility model precast plate docking assembling members embodiment.
Detailed description of the invention
As shown in Figure 1, precast plate docks assembling members, comprises the channel-section steel 1 of two notch positioned opposite, and the top 4 of channel-section steel 1 and following 5 offsets with adjacent two precast plates respectively; Two channel-section steels 1 are provided with rectangular through-hole, are interspersed with the tension part 2 that rectangle steel bar is made in rectangular through-hole, and one end of tension part is provided with block 6, and the teeth 3 that the other end is provided with equidistant setting are used in conjunction with tension piece; Tension piece is provided with retaining mechanism; The thickness of tension part 2 is no more than 1.5cm, and width is no more than 5cm, and the two ends that tension part 2 is pressed close to channel-section steel 1 back side have additional pad.
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. precast plate docking assembling members, 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 rectangular through-hole, in rectangular through-hole, be interspersed with the tension part that rectangle steel bar is made, one end of tension part is provided with block, and the teeth that the other end is provided with equidistant setting are used in conjunction with tension piece; Tension piece is provided with retaining mechanism; The thickness of tension part is no more than 1.5cm, and width is no more than 5cm.
2. precast plate docking assembling members according to claim 1, is characterized in that: the two ends that described tension part is pressed close to the channel-section steel back side have additional pad.
