Description
Technical field
The utility model relates to a kind of vertical plate types to anchor high-strength anchor bolt, belong to novel integrated building technical field.
Background technique
Anchor bolt is the essential product of steel building, the connection for steel column and basis.Mainly Q235 used at present
With Q345 steel anchor bolt；Traditional anchor bolt mainly uses J-type and two kinds of anchor slab type；J-type anchorage length is " mixed according to GB50010-2010
Xtah Crude Clay structure design specification " calculating of 8.3.1 item, using 180 degree crotch, curved rear straight portion is 4d for end, is detailed in Fig. 1 and table 2；
Anchor slab type is calculated according to GB50010-2010 " Code for design of concrete structures " 8.3.1 item and 8.3.3 item, and end is using welding
Anchor slab is detailed in Fig. 2 and table 2.
Traditional anchor bolt when construction is embedded, often mutually conflicts with concrete reinforcing bar, construction is tired since end has crotch and anchor slab
It is difficult；It is limited to without high-intensitive anchor bolt, some pedestal anchor bolt sections are used very big, and construction and installation can not install, and deviations are very big,
In addition the defects of anchor bolt diameter brings greatly steel column foot and foundation concrete short column is excessive and anchor plate-end and reinforcement foundation are collided, sternly
Steel are wasted again.
In view of this, the applicant specializes in this, develop a kind of vertical plate type anchoring high-strength anchor bolt, this case by
This is generated.
Utility model content
In order to solve drawbacks described above existing in the prior art, the purpose of the utility model is to provide a kind of anchorings of vertical plate type
High-strength anchor bolt, to achieve the goals above, the technical solution that the utility model is taken are as follows:
A kind of vertical plate type anchoring high-strength anchor bolt, including anchor pole and anchored end, the anchored end include at least two pieces and are set to anchor
Vertical plate on bar.
Preferably, the anchored end is equipped with two pieces of vertical plates in the same plane.Anchored end vertical plate type, it is easy for construction,
It will not collide with concrete foundation short column reinforcing bar, energy conservation and environmental protection.
The anchor pole further includes termination point of anchor rod.
The termination point of anchor rod is equipped with screw thread.
Preferably, the termination point of anchor rod is bevel head.Steel reinforcement cage can be passed through, effectively reduces bar bender's
The amount of doing over again.
Preferably, the anchor bolt is 40CrNi2Mo alloy steel.
The utility model is able to achieve following technical effect:
(1) high-strength anchor bolt anchored end takes vertical plate type to anchor, when embedding, since vertical plate plate thickness is smaller than screw diameter, and anchor pole
End uses bevel head, can pass through steel reinforcement cage, effectively reduce the amount of doing over again of bar bender；
(2) under the conditions of same intensity, the utility model is at low cost, and economic benefit is obvious；
(3) after considering that anchor bolt diameter becomes smaller, steel column foot structure also accordingly becomes smaller, and saves steel column foot steel using amount；Basis
Short column also accordingly becomes smaller simultaneously, saves concrete dosage；
(4) anchored end vertical plate type, it is easy for construction, it will not collide with concrete foundation short column reinforcing bar, energy conservation and environmental protection.

Specific embodiment
In order to make the attainable technical effect of technological means and its institute of the utility model, more perfect take off can be become apparent from
Dew, hereby provides one embodiment, and be described in detail as follows in conjunction with attached drawing:
As shown in Figure 4 and Figure 5, Fig. 4 is the structural schematic diagram that the present embodiment vertical plate type anchors high-strength anchor bolt, and Fig. 5 is this reality
Apply a top view for vertical plate type anchoring high-strength anchor bolt anchored end, a kind of vertical plate type anchoring high-strength anchor bolt, including anchor pole 11 and anchoring
End 2, anchored end 2 include at least two pieces vertical plates 21 being set on anchor pole.The anchored end 2 of the present embodiment is equipped with two pieces and is located at same put down
Face upper vertical plate 21.Anchored end vertical plate type, it is easy for construction, it will not collide with concrete foundation short column reinforcing bar, energy conservation and environmental protection.
Anchor pole 1 further includes termination point of anchor rod 11.Termination point of anchor rod 11 is bevel head.Steel reinforcement cage can be passed through, is effectively subtracted
The amount of doing over again of bar bender is lacked.
1. Materials with High Strength is selected: the stress form of anchor bolt is unidirectional tension, is not subject to shearing and moment of flexure；The tension of anchor bolt is held
Carry power formula: Tu=ft a×Ae
A in formulaeIt is the effective tension area of anchor bolt, ft aIt is anchor bolt tensile strength design value；
As can be seen from the above equation, the higher anchor bolt bearing capacity of the strength of materials is higher；At present domestic specification only list Q235 and
The anchor bolt intensity of Q345 steel；
According to above situation, the utility model selects 40CrNi2Mo steel in GB/T3077-2015 " structural alloy steel ", fu b
=1790MPa, GB50017-2003 " Code for design of steel structures " 3.4.1 item, ft a=0.38fu b
It being obtained from the analysis of table 1, the carrying of 40CrNi2Mo steel alloy anchor bolt improves 385.71%,
2. vertical plate type anchored end: traditional anchor bolt mainly uses J-type and two kinds of anchor slab type；J-type anchorage length be by
GB50010-2010 " Code for design of concrete structures " 8.3.1 item calculates, and end uses 180 degree crotch, and curved rear straight part is
4d is detailed in Fig. 1 and table 2；Anchor slab type is according to GB50010-2010 " Code for design of concrete structures " 8.3.1 item and 8.3.3 item
It calculates, Fig. 2, Fig. 3 and table 2 are detailed in using welding anchor slab in end.
Traditional anchor bolt when construction is embedded, often mutually conflicts with concrete reinforcing bar, construction is tired since end has crotch and anchor slab
It is difficult；High-strength anchor bolt anchored end in the present embodiment vertical plate type anchor bolt high-strength anchor bolt system takes vertical plate type to anchor, and is detailed in Fig. 4 Fig. 5
With table 3；When embedding, since 21 plate thickness of vertical plate is smaller than 1 diameter of anchor pole, termination point of anchor rod 11 uses bevel head, can pass through steel
Muscle cage, effectively reduces the amount of doing over again of bar bender.
3. economic comparison
By taking the utility model high-strength anchor bolt M30 as an example, TU=381.208kn, every weight: 14.33kg, by market cost
About 14.33*8=114.64 member/root；
Corresponding close bearing capacity tradition anchor bolt is M64, TU=374.6kn, every weight: 46.28kg, about by market cost
For 46.28*6=277.68 member/root；
Only from material cost itself, so that it may save 59%, economic benefit is obvious；
After considering that anchor bolt diameter becomes smaller, steel column foot structure also accordingly becomes smaller, and saves steel column foot steel using amount；Basic short column
Also accordingly become smaller simultaneously, saves concrete dosage；Anchored end vertical plate type, it is easy for construction, it will not collide with concrete foundation short column reinforcing bar, energy conservation
Environmental protection.
1 Q235 of table and 40CrNi2Mo steel anchor bolt bearing capacity ratio compared with
2 Q235 steel J-type of table and anchor slab type anchor bolt parameter (C15 concrete)
3 40CrNi2Mo steel high-strength anchor bolt anchor bolt parameter (C15 concrete) of table
The above content is combination preferred embodiments of the present invention to further detailed made by provided technical solution
Describe in detail bright, and it cannot be said that the utility model specific implementation is confined to these above-mentioned explanations, technology affiliated for the utility model
For the those of ordinary skill in field, without departing from the concept of the premise utility, several simple deductions can also be made
Or replacement, it all shall be regarded as belonging to the protection scope of the utility model.
