Description
Technical field
The utility model relates to the built-in fitting that a kind of building curtain wall is used, particularly a kind of C type channel-section steel embedded parts of being convenient to install adjustment in work progress.Can be widely applied to all kinds of heavy construction curtain wall engineerings.
Background technology
At present, along with the diversified development of constructure screen wall design and improving constantly of security and stability requirement thereof, the form of the built-in fitting that building curtain wall is used is also constantly changing, and its function is also in continuous reinforcement, to satisfy the requirement that strengthens the building curtain wall aesthetic appearance.In the prior art, the built-in fitting that uses on the building curtain wall mostly is the Connection Block that has adaptor and the pre-buried bar that is fixed on the Connection Block and constitutes.Its Connection Block is generally the channel-section steel shape, and pre-buried bar is generally fixtures such as screw-thread steel, i iron, is by being welded together between Connection Block and the fixture usually.Yet because the defectives such as undercut, pore, slag inclusion, rosin joint, thermal deformation and generation thermal stress that weld exists, this class built-in fitting weld jig, frock are more, troublesome poeration, working (machining) efficiency are low, therefore, it also exists mechanical property instability, the relatively poor shortcoming of supporting capacity, cause its application life lower, safety factor is lower, more and more can not satisfy the requirement of aspects such as curtain wall design, construction.Directly carry out welding processing in the job site that does not have fire prevention measure, be easy to cause fire, both the life-threatening property safety had a strong impact on construction speed again, increased construction cost.Many defectives at above-mentioned built-in fitting existence, at patent announcement number is in " the building built-in fitting " of CN2871676, disclose following technical characterictic: it comprises Connection Block and fixture, on the Connection Block of channel-section steel shape, be provided with equidistant rivet hole, also has a fixed installation hole in the both sides of rivet hole, fixture is a rivet, the head of rivet is hexagonal configuration, the bottom of rivet is provided with one and is umbrella shape shape body, and the end, lower end of rivet and the rivet hole place on the Connection Block form riveted joint to be connected and fixed.Yet still there is following problem in this built-in fitting: at first, the nose shape of rivet is the turret head that is formed by processing round end, processing hexagonal two procedures, takes a lot of work, requires great effort; The second, the bottom of rivet is provided with a umbrella shape shape body, and structure is comparatively complicated, and difficulty of processing is big, is unfavorable for producing in batches; The 3rd, after rivet and the channel-section steel riveted joint, the die top plan is higher than surface, channel-section steel rivet hole place, and then die will interfere with the adaptor that is movably connected in the channel-section steel groove, is unfavorable for installing adaptor.In sum, existing building does not satisfy the requirement that strengthens the building curtain wall aesthetic appearance with the structure of built-in fitting, requires further improvement.
The utility model content
The purpose of this utility model provides a kind of C type channel-section steel embedded parts, fundamentally solve existing building with built-in fitting because problem such as mechanical property instability, supporting capacity that its welding procedure produces be relatively poor, it is compared with built-in fitting with existing similar building, simple in structure, easy to process, saving of labor, laborsaving, the working (machining) efficiency height, being suitable for normalization produces in batches, it is strong to have supporting capacity, improve application life, in work progress, be convenient to install and adjust, can satisfy the advantage of the requirement that strengthens the building curtain wall aesthetic appearance.
The technical solution of the utility model is: this C type channel-section steel embedded parts comprises Connection Block that has adaptor and the pre-buried bar that is fixed on the Connection Block, its technical essential is: described Connection Block is a C type channel-section steel, the counterbore that is connected of boring wall with the heavy nest of recessed formula band of described pre-buried bar riveted joint usefulness is set in described C type channel-section steel bottom surface, the riveted joint head end tensioner of described pre-buried bar is in described C type channel-section steel bottom surface connects the heavy nest awl wall of counterbore, and the end face that makes the plane, top of described pre-buried bar riveted joint and described C type channel-section steel bottom surface at grade, the other end of described pre-buried bar is provided with disc type retaining platform, the described adaptor that is movably connected in the notch place of described C type channel-section steel is a T type bolt, the notch contact surface with described C type channel-section steel of described T type bolt is the inclined plane, and the inclination angle of this inclined plane and described C type channel-section steel notch contact surface matches and fits tightly.
Advantage of the present utility model with positive technique effect is: because the riveted joint tensioner of pre-buried bar of the present utility model is in C type channel-section steel bottom surface is connected the heavy nest awl wall of counterbore, so can pre-buried bar and panel be linked into an integrated entity securely by riveted joint expanding force therebetween.The riveted joint end face of pre-buried bar is concordant with the end face of C type channel-section steel bottom surface, so effectively avoided interfering with the T type bolt at the notch place that is movably connected in C type channel-section steel, and T type bolt can move freely along the notch of C type channel-section steel, adjusts installation dimension at any time, and operation is very easy.Wherein, the riveted joint tensioner of pre-buried bar is in C type channel-section steel bottom surface connects the heavy nest awl wall of counterbore, although this riveted structure is simple in structure but performance is highly stable, safe and reliable, supporting capacity is strong, be connected firmly, fundamentally solved existing building with built-in fitting because problem such as mechanical property instability, supporting capacity that its welding procedure produces be relatively poor.In addition, compare with built-in fitting with existing similar building, the utility model has saved several procedures of processing hexagonal rivet head and fimbriatum on pre-buried bar, save labor, disc type retaining platform directly is set in the other end of pre-buried bar, in the shearing contact area that keeps increase and cement, can also reaches simple in structure, easy to process, the purpose of saving processing cost.The inclination angle of the stressed contact surface in termination of T type bolt and the stressed contact surface of C type channel-section steel notch matches, and fits tightly together, guarantees that two parts are in contact with one another with maximum area in the course of the work, effectively transmits stress load, makes full use of its supporting capacity.To sum up, it is strong to the utlity model has supporting capacity, long service life, is convenient to install the advantage of adjustment in work progress, can satisfy the requirement that strengthens the building curtain wall aesthetic appearance.
