Abstract
The utility model relates to a fixing device for embedding bars, particularly to a fixing part for buildings which is especially suitable for bar embedding working procedure and bar connecting working procedure. The fixing part for buildings comprises steel bars, an expansion casing tube and an expansion pin, wherein the head of the expansion casing tube is provided with an expansion part. The fixing part for buildings is characterized in that at least one end of the steel bars is provided with a transverse bar which is axially perpendicular to the steel bars, and the ends of the steel bars with transverse bars are inserted into the expansion casing tube from the back part of the expansion casing tube. When the steel bars are fastened in the expansion casing tube, the transverse bars arranged at the ends of the steel bars have better retreat stop effect, and thus, joints of the steel bars can be firmly connected with the expansion casing tube. Because poured concrete does not need to be chiseled and excavated in large areas when the fixing part for buildings is used for embedding bars, the utility model has the advantages of convenient construction, time saving, labor saving and increased construction quality.
Description
The utility model bar planting fastening devices relates to a kind of fastening devices for building, is particularly useful for bar planting, connects the use of muscle operation.
Generally, if when on road surface of having built or building, constructing column, at first, need to dig out on former concrete wall or ground one than cavern till expose the reinforcing bar that is embedded in the concrete, then, pick out reinforcing bar from the former steel bars in concrete vertical direction that is embedded in, again, again fluid concrete, this kind operation comprise and burrow, connect muscle, fluid concrete, hardening of concrete phase or the like, and be long in time limit, operation is miscellaneous; Be fixed on the expansion sleeve that is connected with reinforcing bar and can make bar planting in the concrete wall, connect the muscle operation become save time, laborsaving, but the bonding strength between expansion sleeve and steel bar end is the key of technology, usually the reinforcing bar of selling on the market has oblique screw thread, reinforcing bar is easily deviate from along hand of helix, so, sometimes need be with the method for repair welding fixedly reinforcing bar and adapter sleeve, thereby, influenced the progress and the construction quality of construction,, the utility model proposes a kind of new technical scheme for overcoming above-mentioned deficiency.
The purpose of this utility model is: a kind of bar planting fastening devices that comprises expansion sleeve and reinforcing bar is provided, and when the fastening reinforcing bar of expansion sleeve, reinforcing bar is unlikely to be deviate from from sleeve along hand of helix.
The purpose of this utility model can be achieved through the following technical solutions: it has comprised reinforcing bar, expansion sleeve and expansion pin, the head of expansion sleeve has bulge, characteristics are: a termination of reinforcing bar has and the axial vertical cross rib of reinforcing bar at least, and insert in the sleeve at the steel-bar-tip self-expansion sleeve rear portion that will have cross rib.When reinforcing bar is fastened on the expansion sleeve, the cross rib of steel bar end plays the effect of retaining, so, strengthened the fastness of being connected between reinforcing bar and expansion sleeve, in the construction, at first bore the hole of appropriate depth at wall, the expansion pin of the utility model is inserted the bulge of expansion sleeve, self-expanding portion puts into the hole with expansion sleeve, when expansion pin is supported at the bottom of the hole, further beats expansion sleeve, after compel being opened, the bulge of expansion sleeve is fixed in the cinclides, the steel-bar-tip self-expansion sleeve rear portion that will have a cross rib insert in the sleeve and fastening it, promptly finished bar planting, connect the muscle operation, improved construction quality and efficiency of construction.
On the technique scheme basis, be the convenient reinforcing bar that inserts, the expansion sleeve inner wall smooth, and casing expandable portion internal diameter is smaller, forms a step in bulge root sleeve pipe, and steel bar end supports to the step place.
On the technique scheme basis, for improving steel bar end intensity, longitudinal rib can be set, be specially: the steel bar end cross rib is equidistant, and by the longitudinal rib of a pair of axial symmetry cross rib is divided into two sections.
On the technique scheme basis, for improving the anti-back effect, it is staggered that the cross rib of Ribbed Bar can further be designed to two sections cross ribs.
Superiority of the present utility model is: dig destruction because of not needing that the concrete of having poured into a mould is carried out large tracts of land cutter, easy construction, save time, laborsaving, again can firm being connected between invar muscle joint and expansion sleeve, improved construction quality.
Describe in detail below by drawings and Examples.
Accompanying drawing 2. combination perspective view of the present utility model.
Accompanying drawing 3. expansion sleeve half sectional views.
Claims (4)
1. bar planting fastening devices, comprise reinforcing bar, expansion sleeve and expansion pin, the head of expansion sleeve has bulge, it is characterized in that: described reinforcing bar one end head at least has and the axial vertical cross rib of reinforcing bar, and insert in the sleeve at the steel-bar-tip self-expansion sleeve rear portion that will have cross rib.
2. bar planting fastening devices according to claim 1 is characterized in that: described expansion sleeve inner wall smooth, and casing expandable portion internal diameter is smaller, forms a step in bulge root sleeve pipe, and steel bar end supports to the step place.
3. according to claim 1,2 described bar planting fastening devicess, it is characterized in that: the steel bar end cross rib is equidistant, and by the longitudinal rib of a pair of axial symmetry cross rib is divided into two sections.
4. bar planting fastening devices according to claim 3 is characterized in that: two sections cross ribs are staggered.
