Description

A kind of shear wall formwork lower part positioning fastener

Technical field

The utility model relates to build construction technique field, and in particular to a kind of shear wall formwork lower part positioning fastener.

Background technique

Shear wall structure is the common concrete structure type body of skyscraper, and shear wall is by framework of steel reinforcement peripheral hardware formwork erection Plate, then penetration concrete pours.After the overall thickness for determining wall according to construction standards requirement, propped up outside framework of steel reinforcement If template, preferably to play a supporting role, but it be easy to cause reinforcing steel bars exposed after concrete hardening, influences shear wall guarantor Covering thickness, shear wall protective layer thickness is too small to be easy to cause sag of protecting coating, so that reinforcing bar is directly exposed, corrodes, shadow Ring Building Structural Safety.

Template Location outside shear wall body is mainly made of the reinforcing bar of diameter 12-16mm, length and shearing wall thickness It spends identical, is then welded on the reinforced frame of shear wall with electric welding machine, spacer bar easily occurs error in welding, and It is inconvenient to occur correcting when error, to influence the accuracy of Template Location, wall is stretched out at spacer bar both ends after concrete formation Two sides, no concrete protective, last a very long time after easily corrode, influence wall body structure stability.

Utility model content

Problem to be solved in the utility model is to provide a kind of shearing for the above-mentioned deficiency in the presence of the prior art Wall form lower part positions fastener, is placed on the basal plane on basis between shear wall formwork by that will position fastener by vertical bar and transverse bar Shear wall formwork is positioned on framework of steel reinforcement made of braiding, framework of steel reinforcement is fixed on the distance that distance template is fixed with fixture block On, to ensure that the thickness of shear wall protective layer, to solve the above-mentioned problems in the prior art.

To achieve the above object, the utility model uses the following technical solution：

A kind of shear wall formwork lower part positioning fastener, including the U-shaped block for being arranged symmetrically and being open opposite, U-shaped block is by two-arm It forms with the link block of connection two-arm, is connect by cross bar with link block between the U-shaped block, in the two-arm of every piece of U-shaped block The opposite groove of notch is set, and distance of the groove away from link block is equal with the diameter of vertical bar；Further include and the groove phase Corresponding fixture block, the fixture block are embedded in groove through clamping vertical bar come spacer bar skeleton.

Compared with the prior art, the utility model has the advantages that：

1, it is placed on the basal plane on basis between shear wall formwork by the way that fastener will be positioned by vertical bar and the orthogonal butting of transverse bar Made of position shear wall formwork on framework of steel reinforcement, avoid the error occurred using welding spacer bar fixed form, together When, the two sides for not having spacer bar to expose wall are corroded, and then improve wall body structure stability.

2, vertical bar is clamped between U-shaped block two-arm with fixture block and is positioned framework of steel reinforcement, to ensure that shear wall is protected The thickness of sheath, the sag of protecting coating for avoiding shear wall protective layer thickness too small and be easy to causeing are sent out so that reinforcing bar is directly exposed It gets rusty erosion, and then improves Building Structural Safety.

Specific embodiment

In order to make technological means of the utility model, creation characteristic, reach purpose and effect is more clear and is easy to Understand, the utility model is further elaborated with reference to the accompanying drawings and detailed description：

As shown in attached drawing 1, attached drawing 2, a kind of shear wall formwork lower part positioning fastener, positioning fastener 1 is placed on the base on basis By positioning shear wall formwork 2, positioning card in vertical bar 3 and the orthogonal affixed framework of steel reinforcement of transverse bar 4 between shear wall formwork on face The length of part 1 is shear wall's thickness, and including the U-shaped block 11 for being arranged symmetrically and being open opposite, U-shaped block 11 is by two-arm 111 and even The link block 112 for connecing two-arm 111 forms, and is connect by cross bar 12 with link block 112 between the U-shaped block 11, every piece of U-shaped block The opposite groove 13 of notch is respectively provided in two-arm 111, distance of the groove 13 away from link block 112 is equal with the diameter of vertical bar 3, It further include fixture block 14 corresponding with the groove 13, the fixture block 14 is embedded in groove 13 through fixed vertical bar 3 to position Framework of steel reinforcement.

As shown in Fig. 3, the downwardly convex formation triangular prism structure 113 in the bottom surface of the U-shaped block 11 and cross bar 12, sets After template 2, penetration concrete is poured, and concrete rises upwards from 2 bottom of template reaches 1 bottom of positioning card part, and concrete againsts The side of triangular prism 113 rises, and avoids that there are air in positioning 1 bottom surface of fastener, causes framework of steel reinforcement to corrode, influences shear wall knot Structure stability, while the contact surface of positioning fastener and concrete is increased, keep positioning fastener 1 more stable in wall, Jin Erti High-rise shear wall structural stability.

The working principle of the utility model：Positioning fastener is placed on two in the basal plane and shear wall formwork of foundation Position shear wall formwork on placing of reinforcement skeleton, framework of steel reinforcement by vertical bar and transverse bar it is orthogonal it is affixed form, position the length of fastener As shear wall's thickness, to after shear wall positioning marking, equidistant with shear wall outer surface in shear wall is protective layer On position, two rows of frameworks of steel reinforcement are tied up with vertical bar 3 and vertical muscle 4, fastener 1 will be positioned and be placed on the basal plane on basis and two placing of reinforcements On skeleton, will position 11 topstick of U-shaped block of fastener 1 two vertical bars 3 arranged side by side, the both arms length of U-shaped block 11 be protection thickness Degree, plugs fixture block 14, two rows of frameworks of steel reinforcement is fixed on the protective layer position of shear wall, then in shear wall position line restocking If template 2, two rows of templates 2, which are clipped, to be set up by basal plane to wall top multilayer positioning fastener 1, in two rows of 2 outsides of template that template 2 is fixed Securely, then penetration concrete pours, and two rows of frameworks of steel reinforcement are because position the fixation of fastener 1 will not be with concrete Pour into and occur to protrude outside wall, secure the thickness of protective layer well, increase shear wall structure stability, by fixed Bit card part 1 substitutes spacer bar, not will cause and corrodes wall because spacer bar is exposed, influences shear wall structure stability.

Finally, it is stated that the technical solution of the above utility model rather than limit, although referring to preferred embodiment to this reality It is described in detail with novel, those skilled in the art should understand that, it can be to the technical solution of the utility model It is modified or replaced equivalently, without departing from the objective and range of the technical solution of the utility model, should all cover at this In the scope of the claims of utility model.
