Abstract
The utility model provides a connection bolt which comprises a bolt body, wherein a bolt head and a threaded rod are connected to form the bolt body, the threaded rod is provided with threads, the bolt head is provided with a platform connected with the threaded rod, the platform is a cube, and the side of the platform has a taper along the connection direction of the platform and the threaded rod. When the connection bolt is used for connection of a split mounting steel mold board, two ends are not required to be fixed through tools when the bolt is disassembled, the threads of the bolt cannot be damaged after multiple use, after the mold board is connected, connection parts are tight, and a concreting forming effect is good. Therefore, the connection bolt has the advantages of being convenient to use, simple in structure, and capable of effectively reducing production cost of enterprises, and evenness of the surface of the steel mold board can be increased after use.
Description
Technical field
The utility model belongs to building part technical field, especially relates to a kind of connecting bolt that is used for the employed band template of made up Sheet Steel Form plate face locating function of building field.
Background technique
When the made up Sheet Steel Form connects in the prior art, normally used plain bolt connects, need during bolt disassembly to fix with instrument two, be not easy to the dismounting operation, plain bolt makes the bad silk of bolt easily after repeatedly using simultaneously, and the template of using plain bolt to connect, the template connection part is not tight, makes template produce faulting of slab ends easily, and the concrete molding effect is not good.
The model utility content
At above-mentioned defective and the problem of prior art, the utility model embodiment's purpose provides connecting bolt a kind of easy to use, simple in structure.
In order to achieve the above object, the utility model provides following technological scheme: a kind of connecting bolt, comprise bolt body, described bolt body is formed by connecting by bolt head and screw rod, and screw rod arranges screw thread, and described bolt head is provided with platform, platform is connected with screw rod, described platform is square body, described platform and screw rod connecting direction, and platform edges has tapering.
Optimized technical scheme, described tapering are between 20 degree-40 degree.
Further optimized technical scheme, described tapering are 30 degree.
Optimized technical scheme, described land thickness are thickness 8mm--13mm.
Further optimized technical scheme, described land thickness is thickness 11mm.
When connecting bolt of the present utility model connects at the made up Sheet Steel Form, when bolt disassembly, need not to fix with instrument two, can repeatedly use back bolt silk not damage, after template connected, connection part was tight, and the concrete molding effect is good, therefore the utlity model has easy to use, simple in structure, the advantage of enterprise's cost of production can be effectively reduced, and Sheet Steel Form plate surface evenness can be increased after using.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A` generalized section of Fig. 1.
Fig. 3 is plan structure schematic representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
According to Fig. 1, shown in Figure 3, embodiment of the present utility model: a kind of connecting bolt, comprise bolt body, described bolt body is formed by connecting by bolt head 1 and screw rod 2, and described bolt head is provided with platform 3, and platform is connected with screw rod.Among the embodiment, the screw rod vertical section is circular, and circular radius is 7.55mm.Described platform cross section is square, and the square length of side is 11mm, and optimized technical scheme, described land thickness are thickness 8mm-13mm.In the preferred embodiment, described land thickness is thickness 11mm.
According to shown in Figure 2, described platform is square body, described platform and screw rod connecting direction, and platform edges has tapering 31, and described tapering is between 20 degree-40 degree, and in the preferred embodiment, tapering is 30 degree.
The utility model is when connecting the made up Sheet Steel Form, platform just blocks two frames of Sheet Steel Form, in installation, when rewriteeing connecting bolt described in the utility model, connecting bolt can not follow the instrument sense of rotation to rotate, use template surface error control behind the utility model within ± 1mm, the industry standard of satisfied ± 2mm, the tapering of platform do not influence bolt yet and use when making two frame holes up and down error be arranged.
The above; it only is embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion by described protection domain with claim.
