Description
[technical field]
The utility model relates to service sleeve fastening devices in the building operations, relates in particular to a kind of pre-buried fastening devices of not penetration sleeve pipe.
[background technology]
The formation of modern building more and more tends to multi-functional, polygamy is put, maximize, and structure types is also many based on steel concrete.The variation of function increases set aside pre-embedded engineerings such as water, electricity, warm, logical, network and is complicated, and quality requirement is also more and more high.Particularly set aside pre-embedded (the large-diameter high-accuracy sleeve pipe of pre-buried all lengths, the bolt etc.) quantity of industrial construction installing engineerings such as steel rolling mill, cement plant, power plant on Equipment Foundations is many, the precision prescribed height, and difficulty of construction is big.Because technologic complexity and particularity, the quality of sleeve pipe construction quality directly has influence on the quality level of subsequent installation engineering.
The key technology of set aside pre-embedded is how to guarantee that the horizontal movement of built-in fitting and vertical displacement all can be satisfied to design and code requirement.Because embedded part is bigger in the lateral pressure that building of matrix concrete is subjected in the process, in case the built-in process of embedded part is improper or fixing insecure, very easily causes level overproof to off normal or absolute altitude.Subsequent handling can not normally be carried out, even cause economic loss.
The conventional way of prior art has following two kinds:
1. before the concreting, service sleeve adopts direct pre-buried method, in outside of sleeve and the matrix concrete structure nearby reinforcing bar carry out disposable welding and fix, or suitably increase the interim reinforcing bar (shaped steel) of part sleeve pipe fixed.
2. for the more shallow sleeve pipe of the degree of depth, after finishing, the concrete structure construction adopt the method for back perforate to set up sleeve pipe (or preformed hole).
The weak point of above-mentioned technology is:
1. sleeve pipe is all relied on structure in the not enough science of method that is connected and fixed of reinforcing bar nearby, in the concreting process because the influence of lateral pressure, can cause reinforcing bar and sleeve pipe to produce bigger lateral displacement simultaneously, and can not dynamically adjust level and vertical deviation, can't guarantee the accurate of set aside pre-embedded position;
2. carrying out secondary perforate meeting after structure is finished again influences the concrete structure quality, particularly when perforate is big, presses code requirement, can't increase reinforcing rib around the hole, cause local cracking easily, and the labour intensity of secondary perforate is big, long construction period.
[summary of the invention]
The technical problems to be solved in the utility model provides the pre-buried fastening devices of a kind of not penetration sleeve pipe.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is that the pre-buried fastening devices of a kind of sleeve pipe is suitable for the location when the penetration sleeve pipe is not pre-buried, comprise posting and carriage, last posting comprises 2 long margin frames, 2 minor face frames, platform, setscrew nut and positioning bolts; The equal in length of described 2 minor face frames, the two ends of minor face frame are connected with 2 long margin frames respectively, 2 minor face frames and 2 long margin frames surround a rectangle, upper surface in rectangle four limit midpoint is provided with platform, be welded with setscrew nut on the platform, positioning bolt and setscrew nut are by being threaded, and the positioning bolt head is towards the center of coffin, and the axis of four pieces of positioning bolts becomes right-angled intersection; Carriage comprises pallet, pillar and base plate, is provided with setscrew nut around the pallet, and positioning bolt is housed on the setscrew nut, and positioning bolt is towards the pallet center; The pallet below is provided with pillar, and the pillar upper end is connected with tray bottom surface, and the pillar lower end is connected with base plate, and base plate is provided with fixing threaded hole.
In said apparatus, described long margin frame and minor face frame are that shaped steel is made.
In said apparatus, described long margin frame and minor face frame are that channel-section steel is made.
In said apparatus, described long margin frame and minor face frame are that i iron or angle steel or square steel are made.
In said apparatus, described pallet is a steel plate.
In said apparatus, described base plate is a steel plate.
The beneficial effects of the utility model are:
1. it is fixing to adopt posting and carriage that the two ends up and down of sleeve pipe are positioned, and fixing means is reliable, and the displacement of service sleeve can be controlled in the designing requirement scope, and its precision can satisfy or be higher than code requirement fully;
2. it is pre-buried that this method especially is suitable for the interior many sleeve pipes of bulky equipment basis concrete.Not only precision meets the demands, and can save the pre-buried auxiliary material of sleeve pipe greatly.
