Abstract

The utility model discloses a rag bolt preformed hole mould belongs to construction technical field, solves current steel mould problem with high costs, unable assurance structural performance. Anchor bolt preformed hole mould includes the mold core and wraps up in the foam layer around the mold core, the size of mouthful is less than the size of mouthful under the mould on the mould to the size of mouthful is greater than or equal to the size of mouthful under the mold core on the mould. And before concrete pouring, positioning and fixing the foundation bolt preformed hole mould, and then pouring. After the concrete reaches the strength, the mold core is pulled out upwards through external force, and the foam layer is broken. The mold core of the utility model can be used repeatedly, thereby saving the cost and improving the economic benefit; the mold core is made of wood, so that the manufacturing cost is low and the pore-forming quality is good; and cleaning the foam layer, and then performing secondary pouring, wherein the secondary poured concrete and the original foundation concrete are effectively connected into a whole to meet the structural performance requirement.

Description

Anchor bolt box mould

Technical field

The utility model belongs to the realm of building construction, is specifically related to a kind of anchor bolt box mould.

Background technology

Existing anchor bolt box mould directly makes of Plate Welding, such as be welded into the shape that size suitable for reading is less than bottom size, and the trapezoidal anchor bolt box mould that cross section is rectangular, there are following two point defects in such steel die: the first, steel die cost of manufacture is high, and be embedded in concrete to take out and re-use; The second, steel die inner wall smooth, back-grouting is shaken rear easy former concrete and is split, and structure exists quality problems and potential safety hazard.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of anchor bolt box mould, solves the problem that existing steel die cost is high, cannot ensure structural performance.

The utility model solves the technical scheme that its technical problem adopts: anchor bolt box mould, comprise core rod and the froth bed being wrapped in core rod surrounding, described mould size suitable for reading is less than mould bottom size, and mould size suitable for reading is more than or equal to core rod bottom size.

Further, arbitrary cross section of described core rod is rectangle or circle.

Further, described core rod is made up of timber, and described froth bed is bundled on core rod by iron wire.

Further, the described core rod plank that is not less than 20mm by thickness is assembled.

Further, the upper end of described core rod arranges hoisting structure.

Further, described hoisting structure is the circle groove being arranged at core rod upper end.

Further, in the groove of described core rod upper end, anti-skidding rib is also set.

Before concrete placings, anchor bolt box mould located and fixes, then building.Reach after intensity until concrete, upwards extracted by core rod by external force, simultaneously froth bed drawing crack is broken, due to and mould size suitable for reading is more than or equal to core rod bottom size, core rod can be extracted in anchor bolt box.

The beneficial effects of the utility model are: core rod can be reused, and have saved cost, have improve economic benefit; Core rod selects timber, and cost of manufacture is low, and hole quality is good; Carry out second pouring again after cleaning out froth bed, second pouring concrete and former foundation concrete link into an integrated entity effectively, meet structural performance requirements.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is plan structure schematic diagram of the present utility model.

Component, position and numbering in figure: core rod 1, froth bed 2, groove 3, the rope made of hemp buckle 4, suspension hook 5, base surface 6.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As depicted in figs. 1 and 2, the utility model anchor bolt box mould, comprise core rod 1 and the froth bed 2 being wrapped in core rod 1 surrounding, described mould size n suitable for reading is less than mould bottom size m, and mould size n suitable for reading is more than or equal to core rod bottom size d.Arbitrary cross section of core rod 1 is rectangle or circle, is illustrated in figure 2 rectangular-shaped, the length that now mould is suitable for reading and/or the wide length that is greater than mould end opening respectively and/or wide, and mould length and width suitable for reading is more than or equal to core rod end opening length and width.

Core rod 1 can select timber, and in order to ensure the intensity of core rod 1, the plank that core rod 1 is not less than 20mm by thickness is assembled, then to be bundled on core rod 1 by iron wire with cystosepiment and to form froth bed 2.The thickness of froth bed 2 is determined according to above-mentioned upper and lower opening dimensional requirement.

For the ease of extracting of core rod 1, core rod 1 upper end arranges hoisting structure, and described hoisting structure is the circle groove 3 being arranged at core rod 1 upper end, also arranges anti-skidding rib, as shown in Figure 1 in groove 3.In addition, the hoisting structure of core rod 1 can also be other forms such as lifting hole(eyelet).

Use the utility model, before building concrete, mould of first being boxed out by the utility model stone bolt is located, and with reinforcing bar and angle steel reinforced, guarantees that foot bolt is boxed out mould accurate positioning.Mould size suitable for reading is the height in face 6 based on take the altitude really, then carries out building to base surface.Until after concrete reaches intensity, buckle 4 by core rod 1 in bundle jail, groove 3 place with the rope made of hemp, by drive a vehicle or manual chain hoist frame suspension hook 5 pierces into the rope made of hemp and buckles 4 and upwards extract, break after froth bed 2 crimp when extracting core rod 1.Finally, the foam particle in preformed hole is cleaned out, so that second pouring.
