Abstract

The utility model relates to an inserting type prepared hole grouting steel bar lapping and connecting member. The connecting construction of steel bars of the prior building industry is complicated. The inserting type prepared hole grouting steel bar lapping and connecting member comprises a precast concrete member (1) which is provided with an embedded steel bar (2), the side of the embedded steel bar is provided with a prepared hole (3), reinforcing ribs are distributed on the peripheries of the embedded steel bar and the hole along a length direction, and the inner part of the hole is connected with a grouting hole (5) and an exhaust hole (6). The utility model is used for the lapping connection of the steel bars in a precast concrete structure.

Description

Plug-in type preformed hole grouting bar splicing connecting elements
Technical field:
The utility model relates to a kind of assembling connecting elements that adopts reinforcing bar plug-in type overlap joint to connect, and is specifically related to a kind of reinforcing bar connecting elements housing industrialization, prefabricated concrete structure that is suitable for.
Background technology:
In cast-in-place concrete structure, the connection of reinforcing bar adopts overlap joint to connect, be welded to connect or mechanical connection method such as compression sleeve more, wherein the overlap joint of reinforcing bar connects the simplest, be welded to connect or the construction of mechanical connection such as compression sleeve comparatively complicated, but these traditional constructions must be finished the connection of reinforcing bar before fluid concrete, are not suitable for the fabricated construction worker method of precast concrete.
Summary of the invention:
The purpose of this utility model provides a kind of plug-in type preformed hole grouting bar splicing connecting elements, utilizes the reserving hole on precast concrete embedded bar next door to realize being connected the overlap joint of reinforcing bar and embedded bar, and is simple to operate, dependable performance.
Above-mentioned purpose realizes by following technical scheme:
Plug-in type preformed hole grouting bar splicing connecting elements, its composition comprises: precast unit, described precast unit has embedded bar, described embedded bar next door is reserved with hole, described embedded bar and hole periphery are arranged reinforcing rib along its length, inner grout hole and the steam vent of connecting of described hole.
Described plug-in type preformed hole grouting bar splicing connecting elements, the described hole inwall non-smooth-shaped that is shaped as along its length comprises corrugated or shape of threads or groove shape or point-like.
Described plug-in type preformed hole grouting bar splicing connecting elements, described reinforcing rib is helical form or closed circular ring-type.
Described plug-in type preformed hole grouting bar splicing connecting elements, described grout hole is connected in the bottom of hole, and described steam vent is connected in the top of hole.
The beneficial effects of the utility model:
1. the reinforcing bar attended operation that realizes of the utility model is simple, and work progress does not need complicated mechanical equipment and facility, does not need power consumption yet.The non-smooth-shaped of reserving hole inwall, hole and embedded bar periphery pre-buried reinforcing rib can further strengthen and be connected effect, so switching performance is reliable, characteristics are built in the construction that is suitable for the housing industrialization precast concrete again.This product construction quality is easy to guarantee that the job site is to do operation substantially, has fully avoided all disadvantages of traditional reinforcing bar connected mode.
2. building course environmental protection and energy saving, reduce cost, save construction fund.
Description of drawings:
Accompanying drawing 1 is undulatory structural representation for this product hole inwall.
Accompanying drawing 2 is the top plan view of accompanying drawing 1.
Accompanying drawing 3 is the screw-shaped structural representation for the hole inwall.
Accompanying drawing 4 is the structural representation of groove shape for the hole inwall.
Accompanying drawing 5 is the structural representation of point-like for the hole inwall.
The specific embodiment:
Embodiment 1:
Plug-in type preformed hole grouting bar splicing connecting elements, its composition comprises: precast unit 1, described precast unit has embedded bar 2, described embedded bar next door is reserved with hole 3, described embedded bar and hole periphery are arranged reinforcing rib 4 along its length, inner grout hole 5 and the steam vent 6 of connecting of described hole.
Embodiment 2:
Plug-in type preformed hole grouting bar splicing connecting elements, its composition comprises: precast unit 1, described precast unit has embedded bar 2, described embedded bar next door is reserved with hole 3, described embedded bar and hole periphery are arranged reinforcing rib 4 along its length, inner grout hole 5 and the steam vent 6 of connecting of described hole.Described reinforcing rib external diameter is greater than hole and the total external diameter of embedded bar.
Described plug-in type preformed hole grouting bar splicing connecting elements, described hole inwall along its length be shaped as non-smooth-shaped, can be corrugated or shape of threads or groove shape or point-like.
Described plug-in type preformed hole grouting bar splicing connecting elements, described reinforcing rib is helical form or closed circular ring-type.
Described plug-in type preformed hole grouting bar splicing connecting elements, described grout hole is connected in the bottom of hole, and described steam vent is connected in the top of hole.
Accompanying drawing 2 in conjunction with the accompanying drawings 1,, the corrugated hole 3 of plug-in type preformed hole grouting bar splicing connecting elements is reserved in the next door of precast unit embedded bar 2 lower ends, design has and is attached thereto logical grout hole 5 and steam vent 6 on the corrugated hole 3, is embedded with the reinforcing rib of arranging along the hole lengths direction 4 at corrugated hole 3 and embedded bar 2 peripheries simultaneously.When this precast unit is installed through lifting, make that being connected reinforcing bar 7 inserts corrugated hole 3 to the design lap length, and seal slit between reinforcing bar and the hole mouth with elastic rubber sealing ring 8, afterwards by grout hole and the scavenging action that utilizes steam vent, can in the corrugated hole, pour into the grouting material, two reinforcing bars can be connected in one by the adhesion strength behind the grouting material setting and harden.
Connecting method for reinforcing bars of the present utility model can be manufactured in concrete pouring and carry out after finishing, and therefore this connecting method for reinforcing bars meets the fabricated construction worker method of precast concrete.
In order to strengthen the connection effect of overlap joint, reserving hole inwall shape along its length can be designed to non-smooth-shaped such as corrugated, shape of threads, groove shape, point-like.In addition, be embedded with the reinforcing rib of arranging along the hole lengths direction, further the effect of stiffener overlap joint connection at hole and embedded bar periphery.
