Abstract
The utility model relates to an umbrella type anchor pin for building, which is used for pulling protection poles arranged on the foundation pit edge and slope. The utility model is characterized in that an anchor head is of an umbrella shape, at least two reaction boards are arranged on the anchor pin on the back of a circular steel conical head, and the reaction board can open and close towards the anchor pin; a pull force is applied after the anchor head is pushed into a certain position, the reaction board opens in an umbrella shape, the pull and fixation of the protection are completed by using the pull force which is passed to the anchor pin after being transferred by a pressure, and the pressure is produced by the action to the reaction board from the negative soil. The utility model has the advantages of simple structure, reasonable design. Compared with a traditional anchor pin, the utility model simplifies construction, saves labour and material, and cuts cost by 20% to 40 %.
Description
The utility model relates to a kind of anchor pole for building, especially for the fixing anchor pole of fender post.
Anchor pole in the soil property stratum occurs having gone through 50 years in Germany after World War II, but basic technology is still the way of imitative rock matter anchor pole, promptly hole, insert anchor pole, grouting, the way that is pressed into or squeezes into isometrical anchor pole is also arranged, all there is the cost height in these ways and the not high shortcoming of bearing capacity.At present, along with the base pit engineering of super highrise building basement rolls up, stable for keeping excavation slope, anchor pole is employed more widely.Thereby be badly in need of a kind of new-type anchor pole that can overcome traditional anchor pole shortcoming.
The purpose of this utility model is improved traditional anchor pole and a kind of umbrella formula anchor pole is provided.
The technical solution of the utility model is, a kind of umbrella formula anchor pole, has anchor head, described anchor head is the umbrella frame shape, it has a round steel conehead, and the anchor pole at conehead rear portion is provided with at least more than one reaction plate, and reaction plate head and anchor pole flexibly connect by pin, the rear end is connected with flexible tie rod, and the other end of flexible tie rod is fixed on the anchor pole.Like this, when anchor pole advances, the umbrella frame shape reaction plate closure on the anchor head, arrive the after-applied pulling force of certain position, umbrella frame shape reaction plate opens, and utilizes the counter-force of being broken ground that the pressure of plate is born the pulling force that passes to anchor pole, thereby anchor pole is finished the tractive of fender post is fixed.
This umbrella formula anchor structure is simple, reasonable in design, compares with traditional anchor pole, simplifies construction technology greatly, save material and manpower, reduction of erection time is also improved degree of safety and the confidence level that anchor draws member, and cost will reduce by 20～40% simultaneously, thereby produces the huge social economic benefit.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Fig. 1 is the schematic diagram that umbrella formula anchor bolt construction uses.
Anchor head schematic diagram when Fig. 2 is the propelling of umbrella formula anchor pole.
Anchor head schematic diagram when Fig. 3 is umbrella formula anchor pole tractive.
1-round steel conehead among the figure, 2-pin, 3-reaction plate, the flexible tie rod of 4-, 5-anchor head, 6-anchor fine strain of millet, the hollow reciprocating type jack of 7-, 8-jack reaction frame, 9-fender post.
Shown in Fig. 2,3, head round steel conehead 1 rear portion is connected with reaction plate 3 by pin 2, and the rear portion of reaction plate 3 has flexible tie rod 4 and anchor pole to link.Reaction plate 3 can be that the umbrella frame shape opens or closed with respect to anchor pole like this.
This umbrella formula anchor pole user mode as shown in Figure 1.Umbrella formula anchor pole passes excavation slope and safeguards stake 9 and anchor beam 6, by hollow reciprocating type jack 7 it is advanced in the soil property stratum, and the other end of jack 7 acts on the jack reaction frame 8.When anchor head 5 behind certain depth, hollow reciprocating type jack 7 applies reversal interlocking relay, this moment, the reaction plate 3 on the anchor head opened, the other end of anchor pole is locked on the anchor beam 6 by screw, so promptly utilizes the pressure of being broken ground to finish anchor pole the tractive of fender post is fixed.
The reaction plate of this umbrella formula anchor pole is more than one at least, and its preferred plan is 1-8.Anchor pole adopts the round steel or the steel pipe of 22～42 millimeters of diameters, better effects if.
Claims (2)
1, a kind of umbrella formula anchor pole, has anchor head, it is characterized in that described anchor head is the umbrella frame shape, it has a round steel conehead, the anchor pole at conehead rear portion is provided with at least more than one reaction plate, reaction plate head and anchor pole flexibly connect by pin, and the rear portion is connected with flexible tie rod, and the other end of flexible tie rod is fixed on the anchor pole.
