Abstract
The invention relates to a corrugated pipe fixing method for positioning a foundation bolt. According to the method, an equipment basis is built firstly, then a corrugated pipe with a diameter and depth slightly larger than those of a preformed hole is selected, and the upper end and the lower end of the corrugated pipe are both sealed with steel covers with diameters equal to the diameter of the corrugated pipe. The method further comprises the steps that a, the upper portion, the middle portion and the lower portion of the outer side of the corrugated pipe are respectively and sequentially clamed with two rebars in both the longitudinal direction and the horizontal direction to form an intersecting-parallel shape, the two rebars clamping the upper portion of the corrugated pipe are connected with rebars on the upper row of the equipment basis in a welding mode, and the rebars clamping the middle portion of the corrugated pipe and the rebars clamping the lower portion of the corrugated pipe are connected with a supporting system of the equipment basis in a welding mode; b, at least one rebar is welded to the bottom end of the corrugated pipe to serve as a bottom support, and at least one rebar is additionally arranged at the top end of the corrugated pipe to serve as a capping. According to the corrugated pipe fixing method for positioning the foundation bolt, fast and accurate positioning is achieved, and the accuracy of a foundation bolt hole is guaranteed.
Description
Technical field
The present invention relates to a kind of bellows fixing means, specifically the bellows fixing means of positioning stone bolt.
Background technology
Large equipment base stone bolt hole number is many, accuracy requires high.How to guarantee that the accurate location of anchor (bolt) hole is crucial, first consider to adopt which kind of material to make mould, then which kind of mode consideration adopts fix.If adopt veneer as mould: one, fabrication cycle is long, can not meet duration needs; Two, partly bolt holes slenderness ratio is larger, and as adopted pattern glue plywood to make mould, form removable difficulty, is difficult to guarantee not clamping of concrete; And hole inwall dabbing difficulty.Three, in concreting process, due to the necessary back cover of mould end opening, pattern glue plywood mould can not weld, and mould can produce buoyancy, is difficult to guarantee bolt hole projected depth.
Summary of the invention
The present invention is intended to overcome the defect of prior art, and a kind of bellows fixing means of positioning stone bolt is provided, can be fast, accurate location, guaranteed the accuracy of anchor (bolt) hole.
In order to solve the problems of the technologies described above, the present invention is achieved in that
A kind of bellows fixing means of positioning stone bolt, first build equipment Foundations, then select diameter and the large bellows of depth ratio preformed hole, it is characterized in that: at the two ends up and down of bellows, all adopt and the isodiametric steel cap seal of bellows mouth, it also comprises the steps:
A. the longitudinal and transverse direction of the upper, middle and lower outside bellows is clamped with two reinforcing bars respectively successively, become groined type, and two reinforcing bars that clamp bellows top are welded to connect with the upper placing of reinforcement of equipment Foundations, will clamp in the middle part of bellows and the reinforcing bar of bottom and the support system of equipment Foundations are welded to connect;
B. in the weldering of the bottom of bellows end, establish at least one reinforcing bar as collet.
The bellows fixing means of described positioning stone bolt, is characterized in that: on the top of bellows, set up at least one reinforcing bar and bear down on one.
The bellows fixing means of described positioning stone bolt, is characterized in that: it also comprises S drag hook, by S drag hook, bellows and equipment Foundations colligation is firm.
The invention has the beneficial effects as follows: the fixing means of bellows has guaranteed the accuracy of anchor (bolt) hole, improved the pre-buried speed of anchor (bolt) hole, reduced the Mold Making time, save manually, reduced cost.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the present invention is described in further detail:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top of line pipe and the structural representation that reinforcing bar is established in bottom weldering.
The specific embodiment
As shown in Figure 1: a kind of bellows fixing means of positioning stone bolt, first build equipment Foundations, then select the bigger bellows 1 of diameter and depth ratio preformed hole, all adopt and isodiametric steel lid 2 sealings of bellows at the two ends up and down of bellows, it also comprises the steps:
A. the longitudinal and transverse direction of the upper, middle and lower outside bellows uses respectively two reinforcing bars 3 by its clamping successively, become groined type, and two reinforcing bars that clamp bellows top are welded to connect with the upper placing of reinforcement of equipment Foundations, will clamp in the middle part of bellows and the reinforcing bar of bottom and the support system of equipment Foundations are welded to connect;
As shown in Figure 2: b. establishes two reinforcing bars 3 as collet in the weldering of the bottom of bellows 1 end; On the top of bellows, setting up two reinforcing bars 3 bears down on one.The present invention also comprises S drag hook, by S drag hook, bellows and equipment Foundations colligation is firm.
Claims (3)
1. the bellows fixing means of a positioning stone bolt, first build equipment Foundations, then select diameter and the large bellows of depth ratio preformed hole, it is characterized in that: at the two ends up and down of bellows, all adopt and the isodiametric steel cap seal of bellows mouth, it also comprises the steps:
A. the longitudinal and transverse direction of the upper, middle and lower outside bellows is clamped with two reinforcing bars respectively successively, become groined type, and two reinforcing bars that clamp bellows top are welded to connect with the upper placing of reinforcement of equipment Foundations, will clamp in the middle part of bellows and the reinforcing bar of bottom and the support system of equipment Foundations are welded to connect;
B. in the weldering of the bottom of bellows end, establish at least one reinforcing bar as collet.
2. the bellows fixing means of positioning stone bolt according to claim 1, is characterized in that: on the top of bellows, set up at least one reinforcing bar and bear down on one.
