Abstract
The utility model discloses a pre-buried structure of an ultra-deep foundation bolt. The pre-buried structure comprises a sleeve with an upward opening, wherein the sleeve is composed of five steel plates; anchor plates are respectively arranged on the outer side faces of the sleeve; the foundation bolt is vertically arranged in the center of the sleeve; the sleeve is filled with a shrinkage-free grouting material; a reinforcing steel plate is arranged at the top of the sleeve; the foundation bolt penetrates through the reinforcing steel plate. As the technical scheme is adopted, the pre-buried structure is simple in structure and convenient to construct; the anchor plates are respectively welded on the four outer side faces of the sleeve consisting of the five steel plates, so that the anchoring effect of the sleeve in concrete foundation can be greatly increased, and the defect that the junction surfaces of the steel plates and concrete are small in coefficient of friction resistance. Moreover, the pre-buried structure is constructed together with equipment foundation, and does not need to be taken out, so that the pre-buried quality of the ultra-deep foundation bolt can be ensured, the operating requirement of the foundation bolt is reliably ensured, and the manpower and time cost that templates need to be taken out in the prior art are reduced.
Description
Technical field
The utility model relates to a kind of pre-buried structure, is specifically related to a kind of pre-buried structure of super dark stone bolt.
Background technology
In industrial construction, according to all needing to configure various production equipments in a lot of workshops of technique instructions for use, these equipment are fixed by stone bolt and equipment Foundations.According to the operating condition of distinct device, stone bolt will bear pressure, uplift force, and the horizontal direction component producing in the time of sometimes also will bearing equipment operation, so the quality of the reserved quality of stone bolt directly affects top equipment operation.The pre-buried structure of equipment anchor bolt routine has two kinds: the one, and employing plank is template, forms a square box, before equipment Foundations concrete construction, imbeds, and during concrete final set, is extracted again.Its shortcoming is that the preformed hole degree of depth is difficult to ensure card, and wooden model surrounding concrete density is bad, and particularly in super dark preformed hole, wooden model is difficult to extract completely, affects bolt and installs.The 2nd, employing steel pipe is template, when the final set of equipment Foundations concrete, is extracted.Its shortcoming is after punching block is extracted, and concrete hole wall is very smooth, and the hole wall coefficient of friction resistance diminishes, and affects the anchorage effect of stone bolt.
Summary of the invention
The technical problem that the utility model solves is: a kind of simple in structure, easy construction is provided, can not only strengthens and the coefficient of friction resistance of concrete joint surface, and do not need the pre-buried structure of the super dark stone bolt that takes out template, to overcome the deficiencies in the prior art.
The utility model is to form like this: it comprises the sleeve 1 that consists of upward opening shape five block plates, at the lateral surface of sleeve 1, be respectively equipped with anchor slab 2, center at sleeve 1 is vertically provided with stone bolt 3, in sleeve 1, be filled with contraction-free grouting concrete 4, at sleeve 1 top, be provided with reinforcement steel plate 5, stone bolt 3 is through reinforcement steel plate 5.
In the pre-buried structure of above-mentioned super dark stone bolt, described stone bolt 3 is welded to connect with the contact position of reinforcement steel plate 5, and reinforcement steel plate 5 is welded to connect with sleeve 1 contact position.
Owing to having adopted technique scheme, compared with prior art, the utility model is simple in structure, easy construction, by welding anchor slab on four sides in the sleeve outside of five block plate compositions respectively, can significantly increase the anchoring effect of sleeve in concrete foundation, make up the shortcoming that steel plate and the concrete joint surface coefficient of friction resistance are little.In addition, the utility model is to construct together with equipment Foundations, does not need to take out, and can guarantee the pre-buried quality of super dark stone bolt, Reliable guarantee the instructions for use of stone bolt, saved the manpower and the time cost that in prior art, need to take out template simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Being labeled as of accompanying drawing: 1-sleeve, 2-anchor slab, 3-stone bolt, 4-contraction-free grouting concrete, 5-reinforcement steel plate, 6-equipment Foundations.
The specific embodiment:
Embodiment of the present utility model: as shown in Figure 1, with five block plate welding, form the sleeve 1 of upward opening shape, at the lateral surface of sleeve 1 anchor slab 2 that is welded respectively, by Steel bar rack, sleeve 1 is fixed in equipment Foundations 6, stone bolt 3 is vertically installed at center at sleeve 1, in sleeve 1, pour into contraction-free grouting concrete 4, at reinforcement steel plate 5 of sleeve 1 welded top, and stone bolt 3 is passed to reinforcement steel plate 5.For further foot bolt 3 firmly, improve installation quality, stone bolt 3 and the contact position of reinforcement steel plate 5 can be welded to connect, and reinforcement steel plate 5 and sleeve 1 contact position are welded to connect.
Embodiment of the present utility model is not limited to above-described embodiment, and the various variations of making under the prerequisite that does not depart from utility model aim all belong to the protection domain of utility model.
