Description
Technical field
The utility model belongs to building enterprise's model sheetinstallat technical field of tools, and in particular to a kind of hollow bolt.
Background technology
Existing cast in situ ferroconcrete wall wall member formwork, two face die plates are positioned by split bolt, to drawing spiral shell
Bolt is by a screw mandrel, and two mountain type cards, two mountain type mother's compositions, wherein mountain type card, mountain type is female to have enough to meet the need part, and screw mandrel is used in ground
When lower room shear wall, pool wall, the wall under wet environment, owner do not allow the construction of structures boxed out on wall, screw mandrel is once
Property expendable part, so screw mandrel consumption is very big, shared expense is very important in construction cost.
Utility model content
The purpose of this utility model is to provide a kind of hollow bolt simple in construction, easy for installation.
The technical solution of the utility model is：
A kind of hollow bolt, by cored screw, cross nut and holds out against screw composition, the cored screw is by stud and spiral shell
Head composition, stud and screw head are all cavity structure, and one end of stud is connected with screw head, and the outer surface of stud is complete outer silk knot
Structure, symmetrically offers cross screw in screw head perpendicular to stud, and holds out against screw is matched with cross screw and used；The cross spiral shell
Female to be made up of pipeline section, band ear cylindrical section and outer-hexagonal section, one end with ear cylindrical section is arranged on one end of pipeline section, and outer-hexagonal section is set
Put in the other end with ear cylindrical section, pipeline section is cavity structure, the external diameter and pipeline section that its internal diameter is more than stud can be moved along stud
It is dynamic.
Screw head described in the utility model is corner, anistree or cylinder.
Band ear cylindrical section and outer-hexagonal section described in the utility model all carries internal thread, and pipeline section, band ear cylinder when using
Section and outer-hexagonal section are all enclosed on stud.
The utility model uses above-mentioned technical proposal, and hollow bolt replaces mountain type female during formwork, steel scrap concrete steel muscle leftover pieces
Instead of screw mandrel, " hollow bolt " of the present utility model is the turnover part of reusable edible, and consumption is only steel scrap muscle.Than
Under, if with useless steel bar meter split bolt, its process is：Steel scrap muscle, which is reclaimed, --- smelts --- round steel is made --- machining
Into screw mandrel --- building site is purchased, and can be used in the formwork work of building site；As long as and utilize the utility model after in steel scrap muscle root
According to needing to choose suitable reinforcing bar, it just can directly use in the formwork work of building site, can largely save society human and material resource,
Reduce construction costs.

Embodiment
Embodiment 1
As shown in Figure 1-Figure 3, a kind of hollow bolt, by cored screw 1, cross nut 2 and holds out against screw 3 are constituted, described
Cored screw 1 is made up of stud 1-1 and screw head 1-2, and stud 1-1 and screw head 1-2 are cavity structure, stud 1-1 one end with
Screw head 1-2 is connected, and stud 1-1 outer surface is complete outer silk structure, is symmetrically offered perpendicular to stud 1-1 on screw head 1-2
Cross screw 1-3, holds out against screw 3 is matched with cross screw 1-3 and used；The cross nut 2 is by pipeline section 2-1, band ear cylindrical section
2-2 and outer-hexagonal section 2-3 compositions, one end with ear cylindrical section 2-2 are arranged on pipeline section 2-1 one end, and outer-hexagonal section 2-3 is arranged on
The other end with ear cylindrical section 2-2, pipeline section 2-1 is cavity structure, and its internal diameter is more than stud 1-1 external diameter and pipeline section 2-1 can be suitable
Stud 1-1 movements, described band ear cylindrical section 2-2 and outer-hexagonal section 2-3 carry internal thread, and pipeline section 2-1, band ear when using
Cylindrical section 2-2 and outer-hexagonal section 2-3 are enclosed on stud 1-1.
Screw head 1-2 described in the present embodiment is corner, anistree or cylinder.
Specifically used method：
Cored screw 1, cross nut 2, holds out against screw 3 is assembled into a hollow bolt, sees Fig. 1, and selection can insert hollow
The reinforcing bar reinforcing bar length of pitch is determined as needed by branch die worker, then is equipped with mountain type card, and then two ends are inserted hollow respectively
Bolt, tightens holds out against screw 3, with regard to composition function and split bolt identical assembly, sees Fig. 4, as long as rotating cross nut 2,
Just the distance between two relative mountain type cards can be compressed or loosened expansion.
Combination shown in Fig. 5, is to install a hollow bolt upset, the distance between mountain type card only passes through right side cross
Nut is adjusted, although so the distance between mountain type card adjustment amplitude diminishes, and can use the reinforcing bar of short point.In figure on cored screw
The cross bore of holds out against screw is installed, only two holds out against screw need to be installed by the upper lower opening of diagram, holes or so hole is standby hole in addition,
Threaded off when by repeatedly circulation, installing internal thread abrasion in the hole of holds out against screw, it is impossible to when reusing, holds out against screw is installed to standby
With just being continuing with hole.
The utility model inflated diameter be Φ 14, institute supporting mountain type card on aperture also preferably Φ 14, such as want supporting aperture
During for Φ 16, Φ 18, Φ 20 mountain type card, adaptable hollow bolt can be designed.
