The utility model discloses a set up the sheathed tube form to big steel mould through-wall bolt, the construction method of big steel mould through-wall bolt has been updated, its beneficial effect is that ① sleeve pipes can be used as the wood rod of top, save the reinforcing bar raw materials, and the processing and the installation expense of top mould rod, ② sleeve pipes are big with big steel mould contact surface, be difficult for making the big steel mould into the pit form destruction, ③ sleeve pipes are good with big steel mould wholeness, big steel mould is difficult for taking place the distortion, easily make level, the alignment, ④ through-wall bolt demolishs swiftly, save big steel mould time of transporting backwards, can avoid the difficult defect of demolishing of through-wall bolt simultaneously, ⑤ through-wall bolt sleeve pipes demolishs, can multiplex ground reuse, reach energy saving and consumption reduction purpose.

The utility model has the advantages that:

1. and (4) economy. The sleeve can be used as a wood jacking rod, so that the raw material of a steel bar and the processing and mounting cost of a jacking rod are saved

2. The protective property to large steel moulds is good. The contact surface of the sleeve and the large steel die is large, and the large steel die is not easy to be damaged in a pit shape;

3. the integrity with the large steel die is good. The sleeve and the large steel die have good integrity, the large steel die is not easy to distort and is easy to level and align;

4. and (5) rapidness. The through-wall bolt is fast to dismantle, the time for transporting the large steel die is saved, and the defect that the through-wall bolt is not easy to dismantle can be avoided

Detailed Description

In order to make the technical scheme of the present invention be more easily and clearly understood, the following description is made in detail with reference to the accompanying drawings and the embodiment of civil engineering large steel mold construction.

(1) When a large steel mould enters a field, the wall-penetrating bolt sleeve is processed and delivered by a manufacturer;

(2) hoisting the large steel mould to a construction wall by a tower crane;

(3) according to the position of a reserved bolt hole of the large steel mould, preliminarily placing a wall-penetrating bolt sleeve to the corresponding position of a wall body, enabling one side of a large head to face the large steel mould which is in place firstly, and slightly fixing the large steel mould by using binding wires;

(4) after the large steel die on one side is placed in place, a wall-penetrating bolt is firstly penetrated to be half or longer, and a wall-penetrating bolt sleeve is penetrated in the process on the basis of not influencing the positioning of the large steel die on the opposite side;

(5) after the big steel mould of opposite is taken one's place, penetrate the wall bolt and fasten, the effect that the wall bolt sleeve pipe still played the mould rod of reaching this moment can save traditional reinforcing bar and push up wooden rod. When fastening, the two sides are symmetrically fastened until the wall bushing is gradually clamped by the large steel die, so far, the clearance of the large steel die is equal to the thickness of the wall body, and the fastening is finished. This process of fastening because the sleeve pipe is the round platform type, and big steel mould area of contact is great, even the fastening is too tight can not cause too big destruction to big steel mould yet, avoids doing the wooden stick with the reinforcing bar, and the fastening is too tight, causes hole form destruction to big steel mould. In addition, the alignment engineering is very quick, the sleeve is clamped tightly, the contact surface of the sleeve and the large steel die is large, the whole of the sleeve and the large steel die is very good, the large template is not easy to distort, and the phenomenon of unqualified verticality and flatness caused by local screwing of the through-wall bolt is not easy to occur.

(6) After the large steel die is fastened, concrete is poured;

(7) after the concrete pouring is finished, the strength reaches a certain value, the through-wall bolt is directly dismantled, and the large steel die is hoisted. The through-wall bolt is dismantled in the step, so that the method is quick, simple and convenient and is not influenced by the bonding of the concrete and the through-wall bolt. The problems that in some cases, certain through-wall bolts are bonded with concrete too tightly and are not easy to remove, other through-wall bolts are removed in advance, the bolts thrown away in front are forgotten to be removed, and finally the large steel mould is hoisted, so that the hoisting cannot be carried out, and the concrete structure can be damaged by the through-wall bolts which are not removed in forced hoisting;

(8) and after the hoisting of the large steel die is finished, when the strength of the concrete reaches the strength of the easily-detachable sleeve, the sleeve is detached again. The special member for removing the sleeve is inserted into the sleeve from one side of the small end of the member to be clamped with the lining of the sleeve, and the sleeve can be removed by lightly knocking. 3 sets of sleeves are processed to ensure the field transportation and use. After the project is finished, the wall bushing can be recovered for the next project.
