Description
Technical field
The utility model relates to the working instrument of a kind of construction formwork, is specifically related to a kind of template and admittedly uses sleeve bolt to tension.
Background technology
In order to ensure safety, the frame construction of main body many employings steel concrete of present high buildings and large mansions, the construction of building frame usually needs to use template, the range determination of template is good, then by split bolt, template is fixed, the intensity of template is ensured, finally fluid concrete in the cavity of template composition finally by form bracing system.
Template is needed to disassemble after concrete setting, concrete steps first dismantle form bracing system, then split bolt is write, finally take off template, in order to split bolt can be extracted out when form removable, usually upper bush can be overlapped on split bolt when installation form, traditional sleeve many employings pvc manages, length is workman's intercepting conveniently, usually there will be pvc pipe long, workman is extruded brokenly when tightening split bolt, cause concrete to enter pvc pipe contact with split bolt and solidify, such split bolt is difficult to take out, equally sometimes pvc pipe intercepts too short, well can not cover split bolt, make concrete can enter pvc pipe equally.The length of split bolt needs the thickness being greater than body of wall usually in addition, and take a large amount of split bolt in an engineering, cost is very high, the trouble that the end-enclosed of last pvc pipe also compares, and takies man-hour more.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of easy to use, and the template that end-enclosed is simple and low to the length requirement of bolt uses sleeve bolt admittedly to tension.
In order to solve the problems of the technologies described above, the utility model provides a kind of template admittedly to use sleeve bolt to tension, include the sleeve that a length equals thickness of wall body and two-layer wall template thickness sum, one end of sleeve is provided with a closed head, this closed head and sleeve adopt engineering plastics injection moulding integrated molding, sealing ring is provided with between closed head and wall form, the other end of described sleeve is provided with internal thread, described internal thread coordinates with fastening bolt, rubber seal ring is provided with between described fastening bolt and wall form, the endoporus of this rubber seal ring extrudes with the outer wall of fastening bolt and coordinates.
The template of technique scheme is adopted to have the following advantages the solid sleeve bolt of tension: the design adopting sleeve and fastening bolt because it is overall, one end of sleeve is provided with a closed head, unitary construction is simple, using method only needs fastening one compared to traditional split bolt, easy to use, owing to being provided with sealing ring between closed head and wall form, such closed head and wall form part can not spillages; Because the other end of sleeve is provided with internal thread, described internal thread coordinates with fastening bolt, and such sleeve instead of the length of a part of fastening bolt, and therefore the length of fastening bolt can significantly shorten, thus reduces the use cost of fastening bolt.
Preferably, be also provided with metallic gasket between described rubber seal ring and fastening bolt termination, time such arranging can make rotational fastener bolt, fastening bolt can not friction damage rubber seal ring-side wall.
Preferably, the center of described closed head is provided with a circular groove, and more simple time such design can make dismounting closed head, directly impacting groove can destroy closed head.
Preferably, described sleeve lining is provided with reinforcing rib in one end relative with internal thread, the cross section of described reinforcing rib becomes M shape, and such design can make the anti-torsional strength of sleeve larger, avoids being destroyed by sleeve in the process of fastening bolt tension.
Accompanying drawing explanation
Fig. 1 is that the utility model embodiment template uses the structural representation of sleeve bolt admittedly to tension.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Reference numeral in Figure of description comprises, wall form 1, sleeve 2, closed head 3, groove 4, sealing ring 5, fastening bolt 6, rubber seal ring 7, metallic gasket 8, reinforcing rib 9.
The utility model provides a kind of template admittedly to use sleeve bolt to tension as shown in Figure 1, mainly include the sleeve 2 that a length equals thickness of wall body and two-layer wall template 1 thickness sum, the length of use middle sleeve 2 can be slightly shorter, be convenient to ensure tightness, one end of sleeve 2 is provided with a closed head 3, closed head 3 and sleeve 2 adopt engineering plastics injection moulding integrated molding, closed head 3 is circle so that process with the cross section of sleeve 2, the center of closed head 3 preferably arranges a circular groove 4, can be simpler when such dismounting closed head 3, direct impact groove 4 can destroy closed head 3, sealing ring 5 is provided with between closed head 3 and wall form 1, to avoid spillage, the other end of sleeve 2 is provided with internal thread, internal thread coordinates with fastening bolt 6, rubber seal ring 7 is provided with between fastening bolt 6 and wall form 1, the endoporus of rubber seal ring 7 extrudes with the outer wall of fastening bolt 6 and coordinates, metallic gasket 8 is also provided with between rubber seal ring 7 and fastening bolt 6 termination, when such rotational fastener bolt 6, fastening bolt 6 can not friction damage rubber seal ring 7 sidewall, sleeve 2 inwall is provided with reinforcing rib 8 in one end relative with internal thread, the cross section of reinforcing rib 9 becomes M shape, the anti-torsional strength of sleeve 2 can be made so larger.
The template of technical scheme is work like this with sleeve bolt to tension admittedly: the overall design adopting sleeve 2 and fastening bolt 6, the internal thread of sleeve 2 coordinates with fastening bolt 6, unitary construction is simple, using method only needs one that locks fastening bolt 6 compared to traditional split bolt, sleeve 2 instead of the length of a part of fastening bolt 6, therefore the length of fastening bolt 6 can significantly shorten, and the sealing ring 5 between closed head 3 and wall form 1 can avoid the spillage of closed head 3.
Above-described is only preferred embodiment of the present utility model; should be understood that for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
