Description
Technical field
The present invention relates to the connector that uses in a kind of building operations, particularly, relate to the wall-connecting piece that exterior wall scaffold and body of wall are connected and fixed in a kind of building operations, in order to guarantee the stable of external scaffolding and to facilitate for the back construction working.
Background technology
Along with development of times, builing industry is advanced by leaps and bounds, and people are in order to save the area, and highrise building is more and more, and shear wall structure is widely used in the builing industry design, and is more and more higher to low-carbon energy-saving, environmental protection that builing industry requires.In recent years in the concrete structure of the construction building, its insulation layer and reinforced concrete structure layer are built simultaneously and are constructed, and this has brought inconvenience for the setting of scaffold connecting spare, and this just needs new technology and new technology to solve.
Summary of the invention
The purpose of this invention is to provide a kind of new type scaffold wall-connecting piece, the new type scaffold wall-connecting piece is simple, convenient, and the joint worker saves time, and construction quality is good.
For achieving the above object, the present invention by the following technical solutions:
Embedded scaffold connecting tube, comprise embedded bar, sleeve, pull bar, wall connecting rod, pad, nut, embedded bar one end stretches out body of wall, and stretch out wall part band straight thread, pull bar two ends band straight thread, sleeve has interior straight thread, and the end that embedded bar stretches out body of wall end and pull bar is fit in the sleeve to be tightened; Drag link sleeve is in wall connecting rod; At the pull bar other end pad is installed, tightens the wall connecting rod that passes with nut and pull bar;
Preferably, embedded bar adopts round steel or the indented bars of diameter 25mm; When concrete is C30, adopt the pre-buried round steel anchorage length of diameter 25mm to be not less than 25 times of bar diameters, adopt its anchorage length of indented bars of diameter 25mm to be not less than 30 times of bar diameters;
Preferably, pad is processed into diameter 100mm plectane with the 6mm steel plate, and at the center according to the perforate of steel bar rod diameter;
Preferably, embedded bar is imbedded a concrete end and is had quarter bend;
Preferably, pull bar adopts reinforcing bar, and pull bar is than the long 100mm of wall connecting rod;
Preferably, sleeve one end shutoff plastic cap;
Preferably, pull bar brush oil when making adds protection plastic sheath (18 in the schematic diagram) and packages;
The job practices of embedded scaffold connecting tube may further comprise the steps:
(1), the preparation before the construction: an end of embedded bar is packaged the straight thread silk and installs sleeve, and processing simultaneously is crooked good, sleeve one end shutoff plastic cap; Adopt the reinforcement fabrication pull bar, the pull bar two ends are packaged the straight thread silk, brush oil adds the protection plastic sheath and packages; The preparation pad is just brought and can be installed and used during with installation.
(2), the construction of built-in fitting: behind building structure main body construction colligation body of wall reinforcing bar, external wall insulation is installed; Carry out the reinforcement installation of pre-buried cover straight thread band sleeve on the body of wall, one of the band sleeve is inserted in the heat-insulation plate for external; Per step support body wall connecting rod should be consistent with the embedded bar absolute altitude, uses the level gauge levelling when pre-buried, guarantees that embedded bar 1 is on same horizontal plane; Install the installation great wall template, position according to its embedded bar, on the side fascia of shear wall large template, beat the eye of φ 6mm with electric drill, tighten with self-tapping screw and sleeve shutoff plastic cap then, the reinforcing bar spot welding of embedded bar other end and wall or plate firmly comes to determine the accuracy of the position of pre-wall-connecting piece; After reinforcing finishes, carry out the walls concrete pouring, remove wall form.
(3), the installation of wall connecting rod: the plastic cap that stops up in the pre-buried sleeve is removed, pull bar and sleeve are installed are tightened, again the scaffold connecting rod tube is entangled band silk reinforcing bar, pad is installed, tighten with screw shell at last, buckle with cross buckle and support body vertical rod or horizontal leger at last and link into an integrated entity.
Preferably, the preparation method of pad is: be processed into the plectane of diameter 100mm with the 6mm steel plate, and at the center according to the perforate of steel bar rod diameter.
Preferably, embedded bar adopts round steel or the indented bars of diameter 25mm, when concrete is C30, adopt its anchorage length of round steel of diameter 25mm to be not less than 25d, adopt its anchorage length of screw-thread steel of diameter 25mm to be not less than 30d, wherein, d is the embedded bar diameter.
The present invention adopts straight thread to be different from the past, and the benefit of regular screw threads is: the screw thread line of straight thread is thick, and the regular screw threads line is thin; The screw thread of straight screw sleeve long (about its cover tube length 60mm), the length that is screwed into is all wrapped up by silk, plain nut screw thread short (about its nut thickness 20mm), the length that is screwed into can not all be wrapped up by silk; It is little influenced by vibration force after straight thread and mantle fiber reinforcing bar are tightened, and is difficult for becoming flexible, and influenced greatly by vibration force after regular screw threads and mantle fiber reinforcing bar are tightened, loosening easily; The straight thread material is good, and the tensile strength height is not easy-to-draw bad, and the regular screw threads material is inferior, and tensile strength is low, draws bad easily.
New type scaffold wall-connecting piece of the present invention has the following advantages: this external scaffolding wall-connecting piece takes the reinforcing bar offal of pre-buried band screw thread to be connected with the sleeve steel bar rod interior with penetrating short steel pipes, the splicing position adopt sleeve, nut and embedded bar with screw thread closely be connected simply firm, be easy to dismounting, constructing for scaffold connecting spare provides new construction technology; Avoided the scene to set up scaffold welding wall-connecting piece and exceeded operating risk, all the node employing is hinged, has accelerated construction speed, has improved the civilized construction level, has guaranteed safety; Ensured that insulating layer of external wall is not damaged; Do not need to carry out the setting of scaffold eye, having stopped is completed pays the maintenance difficult problem of the outer foundation trick seepage in back.
