Description

Zheng Shi precast beam tenon connection connector

Technical field

The invention patent relates to a kind of precast beam jointings

Background technique

According to existing assembly concrete Building technology, primary and secondary beam connecting node position is generally required using grout sleeve The mode poured after connection or node is attached, and applies man-hour requirement and girder is carried out reinforcing bar connection in position of joints and installs mould Plate then entire girder poured in place concrete molding, work progress complex process takes time and effort, and Mass accuracy is difficult to control System, beam cast in situs need to be arranged the support frame of template and complexity, need to expend a large amount of artificial and material, and effect low cost is high

Patent of invention content

In order to overcome existing primary and secondary beam nodes position cast-in-place construction technique complicated, the high problem of cost of manufacture, the present invention A kind of novel primary-secondary beam mortise-tenon joint method is provided, by precast beam by the way of modular connection connection, in conjunction with the cast-in-place work of overlapping Skill is integrally formed, easy for installation, and connection is quick, and securely and reliably, stress performance is good.The invention patent solves its technical problem and is adopted Technical solution is:

The specific manufactured size of Zheng Shi precast beam tenon connection connector is that the end portion width of tenon (1) is 50mm, and root is 100mm, length 100mm, the highly h/3 for beam splice height；Fourth of the twelve Earthly Branches slot (3) oral area width 100mm, root 50mm, depth are 50mm leads to high setting along beam sides；The through-hole that two diameters are not less than 50mm is arranged according to design requirement for mortise (4), from beam Answer >=50mm in upper and lower ends edge；Entire beam splice can be roughly divided into three sections, and first section is tenon (1), and second A section is section where fourth of the twelve Earthly Branches slot (3), and length answers >=200mm, and it is highly entire beam that width, which is the b/2 of entire beam section width, Depth of section h；Third section is the section where mortise (4), and length answers >=200mm, and width is entire beam section width b, Height is entire beam section height h；When precast beam mortise and tenon connector is using steel construction or timber structure and other high-strength composites When material makes, it should be made by dimensions above requirement；When precast beam mortise and tenon connector is precast concrete composite beam form, Depth of beam should take time beam section height to subtract overlapping layers thickness, such as prefabricated beam section height 450mm, overlapping layers thickness when production 120mm, then the height h=450-120=330mm of Zheng Shi precast beam tenon connection connector.

Detailed description of the invention

Fig. 1 is Zheng Shi precast beam tenon connection connector three-dimensional model diagram；Fig. 2 is that Zheng Shi precast beam tenon connection connector is overlooked Figure；Fig. 3 is Zheng Shi precast beam tenon connection connector front view；Fig. 4 is Zheng Shi precast beam tenon connection splice combinations threedimensional model Figure；Fig. 5 is Zheng Shi precast beam tenon connection splice combinations top view；

Zheng Shi precast beam tenon connection connector, including tenon (1), mortise (2), fourth of the twelve Earthly Branches slot (3), mortise (4)；Its feature exists In: the prefabricated beam splice of Zheng Shi be made into comprising tenon (1), mortise (2), fourth of the twelve Earthly Branches slot (3), mortise (4) standard component, when two beam splices One positive (A beam head) one anti-(B beam head) it is combined and spliced when, the tenon (1) of A beam splice is just mounted on the mortise (2) of B beam splice In, two connectors are closely linked after realizing mortise and tenon docking, after the jointing of two sections of beams is directed at installation, Ke Yi The reinforcing bar of insertion fixation, can effectively fix the relative position of two intercept beams in mortise (4), to reduce the upper and lower of beam splice Dislocation.If precast beam is made of precast concrete, composite beam form, including tenon (1), mortise should be made into (2), beam face steel bar stress is passed through hoop when carrying out the binding of beam face reinforcing bar by fourth of the twelve Earthly Branches slot (3), mortise (4), stirrup (5), main reinforcement (6) Muscle (5) is bound, and after completing the concreting of composite beam in-situ layer, concrete fills up fourth of the twelve Earthly Branches slot (3) for consolidating in mortise (4) Determine reinforcing bar to be set in concrete bodies, two beam splices, which are closely linked, can form the common stress of entirety.

When being applied to prefabricated assembled concrete structural construction, can be produced into according to different beam section sizes Product modular connection component, the connection application of the precast beam applied to same cross-sectional size different length, when design, can will need The beam of connection is divided into three sections, and both ends can be integrally formed using standard Zheng Shi precast beam tenon connection connector and girder, intermediate beam Section both ends only need to overturn 180 degree set same size jointing can be used to connection different length precast beam, even It connects simply, it is easy for installation, it is securely and reliably, high-efficient！

Above-mentioned Zheng Shi precast beam tenon connection connector is incited somebody to action in application, when a girder two sides have multiple tracks secondary beam to set up After Zheng Shi precast beam tenon connection connector is formed according to secondary beam design size, size and positioning with girder formed by integrally casting, a master Beam two sides can connect multiple tracks secondary beam simultaneously, and jointing is hold-down support, and holistic resistant behavior is good, and due to primary and secondary There is negative moment of backing plate at girder connection, certain distance be arranged outside primary and secondary beam connecting node in Zheng Shi precast beam tenon connection connector, Can be well by joint arrangement at the lesser position of moment load, stress is relatively reasonable.

Above-mentioned Zheng Shi precast beam tenon connection connector can be applied to prefabricated assembled concrete structure, can also apply to The precast beam connection of steel construction and timber structure and the production of other high strength composites.

The beneficial effect of the invention patent is can to make the modular connection of different cross section size in prefabricated components factory, It only needs to be required according to the beam section size of design, selects the Zheng Shi precast beam tenon connection connector of corresponding specification, a part is used It is formed in girder formed by integrally casting, another part is used for the production of connected precast beam, when in-site installation, it is only necessary to find The secondary beam of same specification carries out docking the connection that precast beam can be completed with the Zheng Shi precast beam tenon connection connector of girder side, peace It is complete reliable and very efficient, since the application of such precast beam Joining Technology can save largely for prefabrication construction Template and support frame will greatly contribute to the promotion and application of prefabrication.
