Background technique
Along with the development of Building technology and the rare of land resources, modern architecture mostly is tall building.For reducing the weight of building self and meeting the industrial policy of the energy-saving and emission-reduction that country advocates, modern architecture is partial to adopt the light block material, as: the light block such as sintered hollow block, sintered perforated brick.By building decoration craft current at present, decorating structure layer need be attached on body of wall, but due to the wall thickness of the light block bodies of wall such as hollow brick inadequate, when therefore using existing EXPANSION ANCHOR BOLTS to carry weight on the light block bodies of wall such as hollow brick, frictional force does not reach 0.3KN usually.According to " the JG/T 366-2012 exterior-wall heat insulation crab-bolt " regulation implemented at present, hollow brick base course wall crab-bolt tensile bearing capacity should be more than or equal to 0.3KN.Therefore, the needs of the light block carrying weight such as hollow brick when using existing EXPANSION ANCHOR BOLTS can not meet building decoration.
Therefore how effectively to improve, solve the tensile bearing capacity of the light blocks such as hollow brick, the structural stage making it adhere to can meet design load and code requirement, is the technical barrier that current decorative engineering practitioner needs solution badly.
Model utility content
The purpose of this utility model is: overcome the above-mentioned defect of prior art, there is provided a kind of brickwork anti-pawl anchoring bolt, to make the light block bodies of wall such as hollow brick provide enough tensile bearing capacity when building decoration, reach " JG/T 366-2012 exterior-wall heat insulation crab-bolt " designing requirement, thus meet the needs of carrying weight.
The utility model is achieved through the following technical solutions:
The anti-pawl anchoring bolt of a kind of brickwork, comprise bolt, pad, the built-in major part of expansion tube, expansion tube and the anti-pawl of anchoring, described bolt is made up of bolt head and stud; The built-in major part of described pad, expansion tube, expansion tube and the anti-pawl of anchoring are enclosed within stud successively, the built-in major part of its Intermediate gasket, expansion tube, expansion tube all not with Stud connection, the anti-pawl of anchoring is threaded with stud; Described pad and bolt head nearest, described expansion tube is provided with opening near one end of the built-in major part of expansion tube.
As the preferred mode of one, the anti-pawl of described anchoring is made up of anti-pawl head and anti-pawl, and described anti-pawl head is threaded with stud, and described anti-pawl head and anti-pawl clamping, described anti-pawl is dispersed to the one end at bolt head place.
As the preferred mode of one, the built-in major part of described bolt, pad, expansion tube, expansion tube and the anti-pawl of anchoring are steel.
As the preferred mode of one, the quantity of the anti-pawl of described anchoring is at least two.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model efficiently solves the problem of the tensile bearing capacity deficiency of fixing bolt on brickwork, is fixed on brickwork the weight energy secure making it carry;
(2) the utility model simple structure is reliable, is easy to install, and reliability is high;
(3) the utility model overall cost is low, and Safety performance is high, and in the application of case history, cost is controlled.
Accompanying drawing explanation

Fig. 3 is a kind of generalized section of hollow brick.
Fig. 4 is the using state figure of anti-pawl anchoring bolt in Longquanyi District, Chengdu hospital curtain wall engineering.
Wherein: 1 stud, the anti-pawl of 2 anchoring, 3 expansion tubes, the built-in major part of 4 expansion tube, 5 pads, 6 bolt heads.
Embodiment
Describe in detail further below in conjunction with accompanying drawing:
See Fig. 1, Fig. 2, the anti-pawl anchoring bolt of a kind of brickwork, comprise bolt, pad 5, the built-in major part of expansion tube 4, expansion tube 3 and the anti-pawl 2 of anchoring, described bolt is made up of bolt head 6 and stud 1; Described pad 5, the built-in major part of expansion tube 4, expansion tube 3 and the anti-pawl 2 of anchoring are enclosed within stud 1 successively, and the built-in major part 4 of its Intermediate gasket 5, expansion tube, expansion tube 3 are not all connected with stud 1, and the anti-pawl 2 of anchoring is threaded with stud 1; Described pad 5 is nearest with bolt head 6, and described expansion tube 3 is provided with opening near one end of the built-in major part 4 of expansion tube.
The using method of anti-pawl anchoring bolt is as follows:
Step one, on retaining wall, hole in random selecting position;
Step 2, inserts in body of wall by anti-pawl anchoring bolt respectively by boring, and when inserting body of wall, boring makes the anti-pawl 2 of anchoring close, until the anti-pawl 2 of anchoring is through boring, the anti-pawl 2 of anchoring opens again;
Step 3, tight a bolt, the afterbody of the built-in major part 4 of expansion tube is just brought in the opening of expansion tube 3, expansion tube 3 starts to expand, anti-pawl anchoring bolt completes fixing, when to anti-pawl anchoring bolt drawing, the anti-pawl 2 of anchoring can produce an active force to the inwall of hollow brick, and then the tensile bearing capacity of product can be made to obtain effective lifting.
As the preferred mode of one, the anti-pawl of described anchoring 2 is made up of anti-pawl head and anti-pawl, and described anti-pawl head is threaded with stud 1, and described anti-pawl head and anti-pawl clamping, described anti-pawl is dispersed to the one end at bolt head 6 place.Arranged by this kind, each piece construction of anti-pawl anchoring bolt is simple and reliable, is easy to install, and reliability is high.
As the preferred mode of one, described bolt, pad 5, the built-in major part of expansion tube 4, expansion tube 3 and the anti-pawl 2 of anchoring are steel.By adopting steel material, the structural strength of anti-pawl anchoring bolt not only effectively can be strengthened.In addition, compared with plastics, steel material is also not easily aging, is convenient to Long-Time Service, the structural failure that can effectively avoid Long-Time Service to produce, and enables anti-pawl anchoring bolt carry out carrying weight normally for a long time.
As the preferred mode of one, the quantity of the anti-pawl 2 of described anchoring is at least two.Arranged by this kind, effectively can strengthen the tensile bearing capacity of anti-pawl anchoring bolt, the reliability of improving product.
The retaining wall of the composition of hollow brick shown in Fig. 3 drills through multiple boring at random, these borings are divided into two-part at random, the anti-pawl anchoring bolt with an anti-pawl of anchoring and the anti-pawl anchoring bolt with two anti-pawls of anchoring is used to be fixed respectively, and carry out strength test, when carrying out strength test, the anti-pawl 2 of anchoring will provide a stretching resistance by body of wall inwall.Described anti-pawl anchoring bolt is steel, and experimental result as shown in Table 1.
