Description

The concrete embedded pin that has enough to meet the need

Technical field

The utility model relates to the concrete blinding fixture, relates in particular to a kind of concrete embedded pin that has enough to meet the need for the fixing concrete template.

Background technology

Have the device for the fixing concrete template now, exist installation rate slow, the problem that the number of turnover is few.For example, shown in Fig. 1, a kind of existing concrete mould board fixer 100 comprises pin 110 and the bolt 120 of truncated cone-shaped, offer on pin 110 outer walls for making pin 110 and template concrete (not shown) mutually chimeric, thereby be fixedly mounted in the helicla flute 111 in the template concrete.Pin 110 inside axially offer the screwed hole corresponding with bolt 120 112 along it, and screwed hole 112 openings are quadrangle, are arranged on the larger end face of pin 110.The screw portion of bolt 120 can screw in this screwed hole 112 affixed with pin 110, and the head of this bolt 120 is exposed at screwed hole 112 outsides, and tool using clamps the head application of force that this bolt 120 exposes, i.e. dismountable this pin 110.The major defect of this concrete mould board fixer 100 is, because the pin 110 in this concrete mould board fixer 100 must be installed in the pin hole of template before concreting, so the screwed hole on it 112 is easily inserted and is damaged by concrete when building; And, after repeatedly pulling out pin 110, the screw thread that bolt 120 and pin 110 engage mutually is fragile, causes these concrete mould board fixer 100 number of turnovers few.

Fig. 2 shows another kind of existing concrete mould board fixer 200.This concrete mould board fixer 200 comprises the embedded nut 210 of hexagonal column and the bolt 220 corresponding with this embedded nut 210.Described bolt 220 can screw in the screwed hole (not shown) of axially offering along it described embedded nut 210 inside, and makes its head be exposed at embedded nut 210 outsides, thereby concrete mould board fixer 200 is stuck in the default hole of template.The major defect of this concrete mould board fixer 200 is, because embedded nut 210 is to be installed in before concreting on template, and its embedded nut 210 is hexa-prism, more difficultly from template concrete (not shown), dismantle, cause the long embedded nut 210 in this concrete mould board fixer 200 to be difficult to recycle, cost is high, and the consuming time more of this concrete mould board fixer 200 is installed; And, after repeatedly pulling out embedded nut 210, the screw thread that bolt 220 and embedded nut 210 engage mutually is fragile, causes these concrete mould board fixer 200 number of turnovers few.

The technical scheme in the invention for solving the technical problem is: the utility model provides a kind of concrete embedded pin 500 that has enough to meet the need, comprise for inserting concrete blinding 600 to fix the pin main body 300 of this template 600, described pin main body 300 comprise the platform shape pin body 320 and with the coaxial column pin handle 310 be connected of this pin body 320; Described pin handle 310 offers the jack 311 of long and narrow slot shape; This jack 311 connects the relative both sides of described pin handle 310, and this concrete embedded pin 500 that has enough to meet the need also comprises that one can insert the latch 400 in this jack 311 accordingly, for by described pin

main body

300 and 600 wedgings of described template.

The concrete embedded turnover in pin 500 that the utility model is above-mentioned, described latch 400 is the trapezoidal pin sheet in a right angle, it comprise parallel upper bottom, perpendicular to the first side of described upper bottom and with the second side of described upper bottom oblique;

Also be formed with an end near described pin handle 310 inclined-plane corresponding with the described second side of described latch 400 on described jack 311 inwalls, and near described pin body 320 corresponding with the described first side of described latch 400, be parallel to the side of the end face that described pin body 320 is connected with described pin handle 310;

Described latch 400 inserts in this jack 311, and the side that is parallel to the end face that described pin body 320 is connected with described pin handle 310 is close in described jack 311 in the described first side of described latch 400, also makes the described second side of described latch 400 be close to the described inclined-plane on described jack 311 inwalls.

The concrete embedded turnover in pin 500 that the utility model is above-mentioned, offer helicla flute 312 on described pin body 320 outer walls, for making described pin main body 300 be embedded in described template concrete seven 00 when inner and described concrete seven 00 is fastened togather securely.

The concrete embedded turnover in pin 500 that the utility model is above-mentioned, described pin handle 310 ends are prismatic structure.

The concrete embedded turnover in pin 500 that the utility model is above-mentioned, the described pin body 320 of described pin main body 300 is also arranging a turntable 321 near on the outer wall of described pin handle 310, be convenient to after described concrete seven 00 solidifies, this pin main body 300 is removed from described concrete seven 00.

The concrete embedded pin 500 that has enough to meet the need that the utility model provides, can remove easily by using tool holding pin handle 310 ends such as spanner the pin main body 300 that hammers into template concrete seven 00, by adopting the embedded structure of the jack 311 on latch 400 and the pin handle 310 corresponding with it, can be by pin main body 300 and template 600 wedgings, installation rate is fast, recycling capable of circulation.
