The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The invention provides a kind of for improving the method for construction work concrete seam quality, use a kind of bolt assembly that improves construction work concrete seam quality, bolt assembly double-screw bolt 1 and nut 2, double-screw bolt 1 comprises handle 3 and the cylinder 4 being connected, nut 2 comprises the nut body 5 of hollow, nut body 5 covers have circular cone build shell 6, on the inner surface of nut body 5, be provided with card 9, the external surface of one end of nut body 5 is cylinder type, the external surface of the other end of nut body 5 is hexahedron type, between the hexahedron end of nut body 5 and shell 6, is provided with groove 7.
Specifically according to following steps, implement:
Step 1, making the first concrete layer 10; Double-screw bolt 1 is screwed into from the cylinder end of nut 2, till card 9 obtains bolt combination body; Bolt combination body is embedded in below the upper surface of the first concrete layer, shell 6 hexahedron ends paste first floor concrete form, and shell 6 is wanted coating release agent, and pour concrete forms the first concrete layer 10;
Step 2, make the second concrete layer 11, till template standing screw 13 is screwed into card 9 from shell 6 away from one end of double-screw bolt 1, second layer concrete form 12 is fixing, completing second layer concrete form installs, double-screw bolt 1 is screwed into from the cylinder end of nut 2, till card 9 obtains bolt combination body; Bolt combination body is embedded in below the upper surface of the first concrete layer, shell 6 hexahedron ends paste first floor concrete form, and pour concrete forms the second concrete layer 11, and as shown in Figure 5, the second concrete layer 11 is positioned at the upper strata of the first concrete layer 10;
In like manner, form the 3rd concrete layer, the 4th concrete layer ..., n concrete layer, finally form total concrete wall;
Step 3, stripping, double-screw bolt 1 is stayed can not recycle and reuse in concrete, and the back-out separated with double-screw bolt 1 by nut 2.
Wherein, a kind of for improving the bolt assembly of construction work concrete seam quality, comprise double-screw bolt 1 and nut 2, as shown in Figure 1, double-screw bolt 1 comprises handle 3 and the cylinder 4 being connected, as Fig. 2, Fig. 3, shown in Fig. 4 and Fig. 5, nut 2 comprises the nut body 5 of hollow, nut body 5 covers have circular cone build shell 6, shell 6 connects together with nut body 5 by injection moulding, on the inner surface of nut body 5, be provided with card 9, card 9 further moves for limiting cylinder 4, it is 8 in the figure mono-that guarantees to be first embedded in concrete and the degree of depth that is screwed into of the screw rod being screwed into for upper former stationary plane, in order to avoid that workman twists while operating is excessive, the external surface of one end of nut body 5 is cylinder type, the external surface of the other end of nut body 5 is hexahedron type, its effect is to guarantee that nut body 5 and shell 6 can extract simultaneously, and can guarantee to pull double-screw bolt 1 separated with nut 2 with Hexagonal jacket, between the hexahedron end of nut body 5 and shell 6, be provided with groove 7, its effect is convenient cover die nut.
Double-screw bolt 1 and nut body 5 are metal material, and shell 6 is plastic material.
Cylinder 4 and nut body 5 are flexibly connected by screw thread 8.
In use, step 1, double-screw bolt 1 is screwed into from the cylinder end of nut 2, the degree of depth is till card 9 obtains bolt combination body;
Step 2, before pour concrete, bolt combination body is embedded in the following 10cm of upper surface of concrete, shell 6 is away from the tight template in one end of double-screw bolt 1, shell 6 is wanted coating release agent, pour concrete forms the first concrete layer;
Step 3, installation second layer concrete form, simultaneously, bolt combination body is embedded in the following 10cm of upper surface of concrete, shell 6 is away from the tight template in one end of double-screw bolt 1, shell 6 is wanted coating release agent, till being screwed into card 9, second layer concrete form is fixed with template standing screw from shell hexahedron end, pour concrete, forms the second concrete layer; As shown in Figure 5, repeating step 1 to 3, forms total concrete wall.
Like this, some intersects the lower end of second layer concrete form with forming the first concrete layer, has prevented the waste of seam, spillage, swollen mould and material.
Step 4, when completing concrete cast and carry out form removal, double-screw bolt 1 is stayed can not recycle and reuse in concrete, nut 2 makes 6 two kinds of different materials of concrete and plastic body shell separated a little by rocking of template standing screw, then with hexagonal socket wrench and back-out separated with double-screw bolt 1 by nut 2, be conducive to the recycling of nut.
The present invention be advantageous in that: utilize the contraction principle separated and mechanical snap of different materials to realize detachable and reusable effect, prevented seam, spillage, swollen mould and material waste easy construction, consumption is extremely low, effect is splendid.
