Abstract

The utility provides a steel mould for precisely preembedding superlong cluster lower margin bolt comprising two upper and lower mould and several steel pipes; the several steel pipes are evenly distributed between upper and lower mould for connecting upper and lower mould which are provided with several through-hole corresponding to lower margin bolt; the upper and lower mould are circular, rectangular or polygon in shape according to distribution of lower margin bolt; the upper and lower mould are provided with reinforced rib for promoting intensity and preventing deformation. The utility has a reasonable structure thereby guaranteeing accuracy of pre-embedding parameter of superlong cluster lower margin bolt, Intensifying engineering quality reliability and stability, reducing labor intensity, saving manpower, shortening construction period; The steel mould, being an ideal mould for precise precast for large scale equipment super long cluster lower margin bolt, is mass produced and can be repeatedly used and widely generalized. The utility has obvious economic and social benefit.

Description

The steel mould that a kind of overlength cluster stone bolt is accurate pre-buried

Technical field

The utility model relates to a kind of construction equipment, particularly a kind of accurate pre-buried steel mould of large equipment base overlength cluster stone bolt that is used for.

Background technology

In the production equipment of industries such as modern oil, chemical industry, space flight, machine, superelevation, super large, overweight tower, horizontal main equipment have a lot, and its basis mostly is the reaction force basis, stone bolt overlength, cluster, layout complexity.For guaranteeing the installation quality of these main equipments, guarantee once to lift, accurately in place, the uniformity that the verticality of overlength cluster stone bolt and top mark are high just seems very important, usually adopt first pre-embedded bolt fixed block at present, again stone bolt be installed, with the construction precision of control overlength cluster pre-embedded anchoring bolts.Form of construction work that can be existing, not only constructor's labour intensity is big, long in time limit, and be difficult to the uniformity that guarantees that each pre-buried parameters precision interrelates between overlength cluster stone bolt, particularly top mark height and verticality, after equipment is installed, also need to add cushion block often and regulate or adopt the concrete secondary levelling, thereby make the installation quality of main equipment can not get guaranteeing.

The utility model content

For overcoming the deficiencies in the prior art, the utility model provides a kind of accurate pre-buried steel mould of overlength cluster stone bolt rational in infrastructure, easy to use, guarantees each the pre-buried parameters precision between overlength cluster stone bolt, improves the installation quality of main equipment.

The technical scheme that its technical problem that solves the utility model adopts is: it comprises two upper and lower templates of annular set up and down and several steel pipe, several steel pipes are distributed in equably and connect upper and lower template between upper and lower template, offer several through holes corresponding to stone bolt on upper and lower template.

The shape of above-mentioned upper and lower template is four limits or polygon shaped as frame according to the distribution of stone bolt.

Be equipped with reinforcing rib in the above-mentioned upper and lower template,, prevent distortion to improve the intensity of upper and lower template.

The beneficial effects of the utility model are: it is rational in infrastructure, guaranteed each the pre-buried parameters precision between overlength cluster stone bolt, strengthen the reliability and stability of workmanship, reduced labour intensity, saved manpower, shortened the duration, batch production is made, and is reusable, and good popularizing value is arranged, be high, heavy, the accurate pre-buried desirable mould of the basic overlength cluster of large equipment stone bolt, have remarkable economic efficiency and social benefit.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the schematic diagram of the utility model construction state.

Among the figure: 1 is that cope match-plate pattern, 2 is that steel pipe, 3 is that lower bolster, 4 is that reinforcing rib, 5 is that through hole, 6 is that lower margin bolt, 7 is a nut.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further specified.

As depicted in figs. 1 and 2, real upper and lower template 1,3 and the steel pipe 2 of comprising of the utility model, annular (the distribution situation of base area foot bolt 6 and deciding, also can be rectangular shaped as frame or other polygon shaped as frame), upper and lower template 1,3 that shape is identical goes to upper and lower corresponding the setting, is provided with ten from shape reinforcing rib 4 in the annular cavity of upper and lower template 1,3.Several steel pipes 2 are distributed in 1,3 of upper and lower templates equably, and its two ends are connected with upper and lower template 1,3 respectively by welding and are connected; On upper and lower template 1, offer several through holes 5 corresponding to stone bolt 6.

As shown in Figure 3, at first the utility model is lifted on the spacer bars, carry out precisely contraposition and the check mutually of axis, control point, fixed behind the horizontal repetition measurement; Then, some stone bolt 6 penetrate respectively in the through hole 5 corresponding on the upper and lower template 1,3, after the top of stone bolt 6 adopts nut 7 to be adjusted to same top mark height, recheck the verticality of every stone bolt 6 once more, the bottom of every stone bolt 6 welds with # font reinforcing bar and reinforcement foundation, if stone bolt 6 length are greater than 1200mm, middle part also must weld with reinforcement foundation on it.Behind stone bolt 6 location, thread is coated with the butter corrosion protection, and puts plastic pipe protection thread and prevent that concrete from polluting.Foot bolt 6 vibrations closely of fluid concrete, plug-in type vibrating head, the bottom surface of lower bolster 3 is exactly the top mark height of base concrete.After treating concrete setting, back out nut 7, the utility model is hung to another place, repeat above-mentioned operation.

Claims
