Abstract
The utility model discloses a reusable split bolt which comprises a split bolt body. A polyvinyl chloride (PVC) sleeve is sleeved outside the split bolt body. The diameter of the PVC sleeve is larger than the diameter of the split bolt body by 3.5mm-4.5mm. The length of the PVC sleeve is equal to sum of wall thickness, double formwork thickness and length of 9mm-11mm. Due to the reusable split bolt, the fact that the reusable split bolt can be polled out and reused after concrete is poured is effectively guaranteed, and therefore economic effect is achieved. The reusable split bolt is simple in operation and can be widely used.
Description
Technical field
The utility model relates to split bolt, relates in particular to a kind of split bolt that can have enough to meet the need use.
Background technology
In shear wall structure (and beam of height＞600mm), installing of template needs to use a large amount of split bolts, and along with the growth of price of steel product, the price of split bolt also soars all the way, traditional after concreting, namely cut off the split bolt that leaks outside, the wide split bolt of residue wall (beam) just is left within the walls, then split bolt is cut off the position and smear the way that rustproof paint is processed, very uneconomical.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of split bolt can have enough to meet the need use, saves a kind of split bolt that can have enough to meet the need use of cost.
A kind of split bolt that can have enough to meet the need use of the present utility model, it comprises split bolt, at described split bolt overcoat PVC sleeve is arranged, the large 3.5-4.5mm of the diameter of bolt is drawn in the comparison of the diameter of described PVC sleeve, and described PVC sleeve length=wall thickness+2 * template is thick+(9 ~ 11) mm.
Adopt this split bolt can guarantee effectively that split bolt can extract out after concreting, turnover is used, and reaches economic effect, and simple to operate, can promote the use of.
Description of drawings
Fig. 1 is that a kind of split bolt that can have enough to meet the need use of the present utility model is installed and used structural representation;
Fig. 2 is the enlarged drawing of the partial structurtes of the split bolt that can have enough to meet the need use shown in Figure 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done to describe in detail.
A kind of split bolt that can have enough to meet the need use of the present utility model as shown in drawings, it comprises split bolt 5, at described split bolt overcoat PVC sleeve 1 is arranged, the large 3.5-4.5mm of the diameter of bolt is drawn in the comparison of the diameter of described PVC sleeve, and described PVC sleeve length=wall thickness+2 * template is thick+(9 ~ 11) mm.It is 4.5-5.5mm that the template length L is stretched out on the preferred every limit of PVC sleeve.
The using method of this split bolt is as follows:
1. one side formwork installs; 2. put into split bolt; 3.Put into polyvinyl chloride (PVC) sleeve pipe; 4. install opposite side template 2, adopt flitch 3 and steel pipe 4 to reinforce; 5 concretings; 6 form removals, and extract the split bolt turnover out and use.7 pairs of PVC sleeve pipes that leak outside cut off processing.
Claims (2)
1. split bolt that can have enough to meet the need use, it is characterized in that: it comprises split bolt, at described split bolt overcoat PVC sleeve is arranged, the large 3.5-4.5mm of the diameter of bolt is drawn in the comparison of the diameter of described PVC sleeve, and described PVC sleeve length=wall thickness+2 * template is thick+(9 ~ 11) mm.
2. the split bolt that can have enough to meet the need use according to claim 1, it is characterized in that: it is 4.5-5.5mm that template length is stretched out on the every limit of PVC sleeve.
