Description
[technical field]
The utility model relates to the pre-buried fastening devices of sleeve pipe in the building operations, relates in particular to a kind of pre-buried fastening devices that is particularly suited for large-scale penetration sleeve pipe.
[background technology]
Set aside pre-embedded (the large-diameter high-accuracy sleeve pipe of pre-buried all lengths, the bolt etc.) quantity of industrial construction installing engineering on Equipment Foundations is many, the precision prescribed height, and difficulty of construction is big.Particularly in the civil engineerings such as steel rolling mill, cement plant, power plant, the quality control on construction of set aside pre-embedded is a very important link.Because mounting process complexity and particularity need, and is relatively large for pre-buried large-diameter high-accuracy penetration sleeve pipe difficulty in the dark pedestal, in case method is improper, very easily causes hidden danger of quality.
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 not firm, very easily causes level overproof to off normal or absolute altitude.Subsequent handling can not normally be carried out, even cause economic loss.
The way of prior art is: before concrete was built, service sleeve adopted 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.
Its weak point 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, concrete is built in the process because the influence of lateral pressure can cause fixedly connected reinforcing bar and sleeve pipe to produce bigger lateral displacement simultaneously.
2. sleeve pipe can not dynamically be adjusted its deviation after fixing, and can't guarantee the accurate position of set aside pre-embedded.
3. it is more that sleeve pipe need use auxilliary material fixedly the time, can not reuse mostly, wastes bigger.

Surround a rectangle, be provided with upper mounting plate at the upper surface of rectangle four limit midpoint, be welded with setscrew nut on the upper mounting plate, positioning bolt and setscrew nut are by being threaded, and the positioning bolt head is towards the center of coffin; Following posting comprises rectangle frame, lower platform, setscrew nut and positioning bolt; Rectangle frame comprises the four edges frame, and the upper surface of the midpoint of every frame is provided with lower platform, is welded with setscrew nut on the lower platform, and positioning bolt and setscrew nut are by being threaded, and the positioning bolt head is towards the center of coffin.
As preferably, described long margin frame and minor face frame are that channel-section steel is made.
As preferably, described rectangle frame is made the four edges frame with channel-section steel and is welded.
As preferably, described lower platform is a steel plate; Described steel plate and frame welding.
The beneficial effects of the utility model are:
1. adopt to go up posting and following posting and the two ends of service sleeve are positioned fixing, the displacement of service sleeve can be controlled in the designing requirement scope fully, 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 penetration of bulky equipment basis concrete, and can save the pre-buried auxiliary material of sleeve pipe greatly.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the pre-buried fastening devices embodiment front view of the utility model penetration sleeve pipe.
Fig. 2 is the pre-buried fastening devices embodiment vertical view of the utility model penetration sleeve pipe.
Among the figure, 1-sleeve pipe, 2-elongated slot steel, the short channel-section steel of 3-, 4-setscrew nut, 5-positioning bolt, 6-angle steel, 7-bolt, 8-nut, 9-channel-section steel, 10-channel-section steel, 11-set bolt, 12-template.
[specific embodiment]
The described penetration sleeve pipe of present embodiment is meant that sleeve pipe penetrates whole substrate when concrete matrix bottom is built on stilts.
In Fig. 1, the pre-buried fastening devices of a kind of penetration sleeve pipe is suitable for the location of penetration sleeve pipe when pre-buried, and this device is made up of last posting and following posting.
Last posting comprises 2 elongated slot steel, 2 short channel-section steels, upper mounting plate, 4 setscrew nuts and positioning bolts 5.The equal in length of 2 short channel-section steels 3, the two ends of short channel-section steel 3 are welded on the centre of 2 elongated slot steel respectively, 2 short channel-section steels and 2 elongated slot steel surround a rectangle, and the side of elongated slot steel and short channel-section steel all up, to constitute the upper surface of channel-section steel midpoint on rectangle four limits as upper mounting plate, be welded with setscrew nut 4 on the upper mounting plate, positioning bolt 5 and setscrew nut are by being threaded, and the head of positioning bolt 5 is towards the center of coffin.
Following posting comprises rectangle frame, lower platform, setscrew nut and positioning bolt.Rectangle frame is made of four channel-section steels 9, and the opening of channel-section steel 9 is welded with the platform that channel-section steel 10 is made in the midpoint of the channel-section steel 9 on every limit up, and Open Side Down for channel-section steel 10, and the back side up.The back side of channel-section steel 10 is welded with setscrew nut 8 in the above as lower platform, and positioning bolt 7 and setscrew nut are by being threaded, and positioning bolt 7 heads are towards the center of coffin.
