Abstract
The utility model relates to a concrete floor, in particular to a construction tool of the concrete floor, namely a dowel bar and preformed hole forming device of concrete floor which comprises a mold plate with through-holes, further a pilot sleeve and a core rod. The through holes of the mold plate are threaded holes, an outer wall of the pilot sleeve is equipped with a threaded segment, and the pilot sleeve is screwed in the through holes of the mold plate and perpendicularly connected with the mold plate via the threaded segment. The pilot sleeve is located inside the mold plate with a flanging which abuts against the mold plate, and the inner wall at the other end is equipped with thread. The pilot sleeve further maintains the relative position between the mold plate and the pilot sleeve through nuts by means of tightening. The core rod is internally provided with through-holes, the outer wall of one end is provided with thread, and the core rod is inserted in the pilot sleeve from the outside and is in threaded connection with the inner wall of the pilot sleeve. The concrete floor is large in fixing area and reliable in positioning, can prompt the position of the core rod inside the concrete, and can avoid when vibrating, thereby largely increasing the quality of the installation of the dowel bars.
Description
Technical field
The utility model relates to concrete floor, relates in particular to the concrete floor construction tool.
Background technology
Between each concrete plate or constuction joint in concrete floor or road construction, by being set, a placing of reinforcement dowel bar transmits shearing between each plate in the middle of this section, by an end of reinforcing bar is fixed, the other end is provided with the needs that preformed hole satisfies telescopic slide between the plate simultaneously.Existing dowel bar preformed hole forming technology is; Form the dowel bar preformed hole by on template, setting in advance pvc pipe.Location, sealing in order to realize this pvc pipe also are equipped with " deck " on template, in the termination of pvc pipe plug is installed, and establish elongated reinforcing bar or iron wire fixes pipe end by burying setscrew underground, drawing.Thus, because the factor of scenario-frame, deck combines with pvc pipe, and fixing etc. of pipe end and iron wire all can be subjected to the influence of the jarring of concrete shock and vibration rod, very easily forms plugging, skew even lacks.
Summary of the invention
The utility model is intended to overcome the problem of utilizing pvc pipe to form the existence of dowel bar preformed hole now, and a kind of concrete floor dowel bar preformed hole shaped device is provided.The utility model fixed-area is big, and the location is reliable, can prevent the possibility that plugging, skew and disappearance take place from structure; The rear end that plug exposes can be played plug position in the prompting concrete again, is dodged when shake is smash, and has improved the quality that dowel bar is installed greatly.
The utility model is achieved in that
A kind of concrete floor dowel bar preformed hole shaped device, comprise the template that is provided with through hole, it also comprises guide sleeve and plug, described template through hole is a screwed hole, described guide sleeve outer wall is provided with thread segment, and be screwed into the template through hole and be vertically connected on template by this thread segment, this guide sleeve is positioned at the template inboard and has flange near template, other end inwall is provided with screw thread, described guide sleeve also keeps relative position between template and the guide sleeve by nut in the mode of tightening, be provided with through hole in the described mandrel body, an end outer wall is provided with screw thread, it from the described guide sleeve of outer insertion and and the guide sleeve inwall to be threaded.
Described concrete floor dowel bar preformed hole shaped device, described plug is plugged with seal at an end through hole that is positioned at template, and the other end is positioned at outside the template and has radial direction through hole.
Described concrete floor dowel bar preformed hole shaped device is provided with sealing ring between guide sleeve inwall and plug.
The utility model has adopted the plug technology to avoid the generation of mortar plug-hole situation fully, and preformed hole position and directional precision have been improved greatly, the outer guide sleeve of template had been pointed out the position of plug when the concrete shake was smash, and can avoid shaking the phenomenon of smashing the impact failure facility and take place.Each utensil such as plug can recycle repeatedly, and guide sleeve does not need to remove from template in turnover is used, and directly has enough to meet the need.The different apertures of reserving only need conversion plug point diameter to realize.Cancelled and buried pvc pipe underground, improved the intensity of reserving hole wall, saved auxiliary material such as large quantities of bases, pipe fitting, pipe plug, bolt, and improved operating efficiency.
Description of drawings
Below, in conjunction with the accompanying drawings, further specify the utility model:
Fig. 1 is a sectional view of the present utility model.
The specific embodiment
As shown in Figure 1: a kind of concrete floor dowel bar preformed hole shaped device, comprise the template 4 that is provided with through hole, it also comprises guide sleeve 2 and plug 1, described template 4 through holes are screwed hole, described guide sleeve 2 outer walls are provided with thread segment, and be screwed into template 4 through holes and be vertically connected on template 4 by this thread segment, this guide sleeve 2 is positioned at template 4 inboards and has flange near template 4, other end inwall is provided with screw thread, described guide sleeve 2 also keeps relative position between template 4 and the guide sleeve 2 by nut 3 in the mode of tightening, be provided with through hole in described plug 1 body, one end outer wall is provided with screw thread, it from the described guide sleeve of outer insertion 2 and and guide sleeve 2 inwalls to be threaded.
Described plug 1 is plugged with seal 7 at an end through hole that is positioned at template 4, and the other end is positioned at outside the template 4 and has radial direction through hole.Between guide sleeve 2 inwalls and plug 1, be provided with sealing ring 5.
The utility model is made up of plug 1 that forms concrete 6 preformed holes and the guide sleeve 2 of fixing its position, guide sleeve 2 usefulness nuts 3 are clamped in template 4 holes, after plug 1 inserts in the guide sleeve 2, rotation is fixed in the cover, prevents jointly that by the O RunddichtringO 5 of screw thread end face and front end mortar from polluting screw thread.After concrete 6 final set, the insertion iron staff is rotated and retreats in the back-out hole of plug 1 afterbody, reaches the purpose of becoming flexible and retreating plug 1.After threaded portion has moved back, directly extract plug 1 out with hand.
Plug 1 inside is provided with closed chamber and pore, during use seal 7 (as little spitball) is filled in closed chamber, stop that mortar leaks from pore, when extracting, little spitball as seal 7 comes off under vacuum pressure reduction, has prevented that vacuum suction and mortar plug-hole phenomenon from taking place.
