Abstract
The utility model provides an active wall-through screw-bolt device, comprising a wall-through screw-bolt rod whose both ends are provided with the thread, and two horn sockets arranged at both ends of the wall-through screw-bolt rod. The outer side of the two horn sockets is provided respectively with two fastening bolt rods, iron cores are arranged in the horn sockets, and the iron core is provided with an inner thread through hole; the outer side of the iron core is provided with a table-cone-shaped nylon contact layer, the nylon contact layer is integrated with the iron core, outer hexagonal nuts are arranged at the bottom end of the iron cores near to the horn sockets, and the nut end surface connected with the iron cores is parallel with the bottom end surface of the horn sockets; the wall can be filled directly with the concrete by using the cone hole remained by the disengagement of the horn sockets, the leakage and the rust can be prevented effectively, and the safety can be ensured. The utility model has the advantages of simple and reasonable structure, low cost, and safe and convenient operation.
Description
Technical field
The utility model relates to a kind of movable through-wall bolt device.
Background technology
On the building site, fluid concrete body of wall conventional method adopts a shank of bolt with band sealing sheet to pass body of wall and template, two rapidss of shank of bolt are provided with external screw thread, cooperate with nut, bonding pad again, play the fixed form effect, concrete pouring is by the time finished, behind the mould metal plate of dismantling, the external survey of concrete wall often leaves the shank of bolt of 250 millimeter, this kind shank of bolt is not before being sliced off, and poor stability is hurted sb.'s feelings easily, also bring very big waste in addition on the one hand, moreover get rusty easily, stay rusty stain at concrete wall, easily corrosion.Chinese patent ZL01224798.7 discloses a kind of detachable through-wall bolt spare that is used for fixing template, technical scheme is: be made up of screw socket in a through-wall bolt bar that has a sealing sheet and two one end band external screw threads, the other end band and the outside of screw socket one end is with the plastic pipe sleeve of a platform taper in band fastening screw tightening latch, make a through-wall bolt bar and two fastening screw tightening latches connect into a detachable through-wall bolt spare that is used for fixing template.The detachable through-wall bolt spare of this kind structure has had some to improve than traditional single shank of bolt structure, makes the wasting phenomenon of steel not have, but still need use the sealing sheet in the application of reality, and corrosion phenomenon takes place easily.
Summary of the invention
In order to design a kind of through-wall bolt device that is used for fixing template simple and reasonable, safe and convenient to use, the technical solution of the utility model is so to realize:
A kind of movable through-wall bolt device, the through-wall bolt bar that comprises a two ends band rib-loop, be located at two horn sockets at through-wall bolt bar two ends, two horn socket outsides are respectively equipped with two fastening screw tightening latches, establish iron core 2 in horn socket 4 and the horn socket 14, iron core 2 is provided with internal thread through hole 1, iron core 2 peripheral hardware platform taper nylon contact layers 3, nylon contact layer 3 is into a single integrated structure with iron core 2, and iron core 2 is being provided with nut 7 near horn socket 4,14 bottom end.
As preferably, nut 7 is the outer-hexagonal nut, and with 2 one-tenth of the iron cores structure that is fixed as one.
As preferably, nut 7 end faces that iron core 2 links to each other are equal with horn socket 4,14 bottom end faces.
Therefore, the utlity model has characteristics such as advantages of simple, cost are low, safe and convenient to use, be easy to penetration and promotion and use.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model horn socket.
The specific embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
Embodiment 1: in conjunction with the accompanying drawings 1, accompanying drawing 2, whole movable through-wall bolt device comprises the through-wall bolt bar 6 of a two ends band rib-loop, be connected with horn socket 4,14 respectively at the external screw thread place at through-wall bolt bar 6 two ends, with reference to accompanying drawing 2, establish iron core 2 in horn socket 4 and the horn socket 14, iron core 2 is provided with internal thread through hole 1, iron core 2 peripheral hardware platform taper nylon contact layers 3, nylon contact layer 3 is into a single integrated structure with iron core 2, iron core 2 is being provided with outer-hexagonal nut 7 near horn socket 4,14 bottom end, and with 2 one-tenth of the iron cores structure that is fixed as one.During installation, horn socket 4 and horn socket 14 symmetries are installed in the both sides of body of wall 9, and 9 one-tenth one planes of bottom one end and body of wall, the template 8 and the template 19 of tape punching is located at the outer survey of body of wall 9 respectively, the external screw thread at through-wall bolt bar 6 two ends enters horn socket 4, half of 14 internal thread through hole 1, about 2 centimetres, the outside of internal thread through hole 1 half respectively by fastening screw tightening latch 5,15 are connected with it, pour concrete, dismounting template 8, before 19, fastening screw tightening latch 5,15 by spanner disengagement horn socket 4,14, dismantle template 8 again, 19, hexagonal or spanner make horn socket 4 by nut 7 in using then, 14 break away from body of wall 9, and body of wall 9 is by horn socket 4,14 break away from and the taper hole that stays is directly mended flat getting final product with concrete, can effectively prevent seepage and get rusty that safety also is guaranteed.
