Abstract
The utility model relates to the field of the manufacturing technology of construction equipment, and in particular relates to an extrusion screw anchorage device which comprises an extrusion screw partially arranged in a support body and a nut in threaded connection with the end part of the extrusion screw, wherein the tail end of the extrusion screw is fixedly connected with a steel strand. In tension construction, the required tensile force can be obtained by manually adjusting the nut with a torque-indicating wrench. The extrusion screw anchorage device provided by the utility model is particularly suitable for the anchorage of expressways, mountains and river slopes and for the explosion-proof support of coal mine tunnels; and without original prestressed tension equipment, the extrusion screw anchorage device solves the problems of inconvenient power supply, no explosion protection, complicated and much equipment and complicated construction of the original construction method.
Description
Technical field
The utility model relates to building implements manufacturing technology field, relates in particular to a kind of extruding screw ground tackle.
Background technology
Used permanent anchor device in the prestressed concrete is in post stretching structure or member, for the pulling force that keeps presstressed reinforcing steel and with its anchoring instrument that is delivered to inside concrete, also is referred to as prestressed anchor.Ground tackle is according to using pattern can be divided into two big classes: (a) stretch-draw end ground tackle: be installed in the presstressed reinforcing steel end and can be in the stretching process of presstressed reinforcing steel all the time to the anchoring instrument of presstressed reinforcing steel maintenance anchoring status.Stretch-draw end ground tackle also can be divided into according to the difference of anchoring pattern: the strand tapered anchorage (YJM) that is used for the stretch-draw prestressing force steel strand, the steel anchoring cone (GZM) that is used for the stretch-draw high tensile steel wire, the pier nose anchor (DM) that is used for heading post tensioning high tensile steel wire, the nut (YGM) that is used for the stretch-draw finish rolling deformed bar is for the cold cast upset head anchor polytypes such as (LZM) of stretch-draw multiply parallel wire unit.(b) fixed end ground tackle: be installed in the presstressed reinforcing steel end, imbed in the concrete usually and not in order to the ground tackle of stretch-draw, also be known as extruding anchor or P anchor.
Prestressed flat ground tackle prestressed anchor, be used for opening earlier, post-tensioned prestressing plate, girderless floor or highly need the beam of reduction, as shown in Figure 2, ground tackle comprises anchor ring 7, intermediate plate 8, and the self-lock force of being combined with the taper hole face of anchor ring by intermediate plate during use pins prestress wire.Existing structural disadvantages is: need for the needs working environment at coal mines, because electronic tensioning equipment needs energising, cause spark easily with electronic tensioning equipment or pneumatic tensioning equipment during ground tackle stretch-draw, have higher danger.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provides a kind of extruding screw ground tackle to solve the problem of carrying tensioning equipment inconvenience in the prior art.
The utility model for achieving the above object, by the following technical solutions: a kind of extruding screw ground tackle, it is characterized in that: comprise that part places the extruding screw of supporting mass and the nut that is connected with described extruding screw end thread, end and the steel strand of described extruding screw are affixed.
The end of described extruding screw is provided with connecting hole, and steel strand place described connecting hole and are fixed together by Extruding spring and extruding screw.
The beneficial effects of the utility model are: 1. can add prestressed method with screw thread at the stretch-draw end steel strand are applied prestressing force; Method with extruding makes ground tackle be connected with steel strand.Ground tackle single steel strand static load pulling force reaches 260KN, and strain 〉=2% meets national standard.
2. only need during stretching construction manually with torque-indicating wrencg tightly moving nut reach required stretching force.The speedway that is particularly suitable for constructing in the open air, massif, river slope anchoring, the needs of the explosion-proof supporting of coal mine roadway.Need not use original prestress tensioning equipment, solve the inconvenience of former job practices power supply, not explosion-proof, equipment complexity, many, construction complicated problems.
3. satisfied domestic and international demand to this product, filled up this product domestic blank, prestressing technique can have been used, particularly the application of field construction, explosion-proof construction works in more areas.
4. the technology level in the project is that the domestic same industry is the highest, extensively adopts domestic state-of-the-art prestressed anchor production technology.As the technology of colding pressing, Numeric Control Technology, process technology automatically.Improve production efficiency, reduced processing cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is structural representation of the prior art;
Among the figure: 1, extruding screw; 2, nut; 3, steel strand; 4, supporting mass; 5, connecting hole; 6, Extruding spring; 7, anchor ring; 8, intermediate plate.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of extruding screw ground tackle comprises that part places the extruding screw 1 of supporting mass 4 and is connected with nut 2 with described extruding bar 1 end thread that falls, and the end of described extruding screw 1 and steel strand 3 are affixed.In the utility model, the end of described extruding screw is provided with connecting hole 5, steel strand place described connecting hole and are fixed together by Extruding spring 6 and extruding screw, be specially elder generation with the outer race Extruding spring of steel strand, an end that is with the steel strand of Extruding spring is inserted in the connecting hole, periphery to extruding screw applies external force at last, and extruding screw, Extruding spring and steel strand are fixed together.In concrete work, rotation nut steel strand will move in supporting mass, thus the prestressing force of control steel strand.
1. can add prestressed method with screw thread at the stretch-draw end steel strand are applied prestressing force; Method with extruding makes ground tackle be connected with steel strand.Ground tackle single steel strand static load pulling force reaches 260KN, and strain 〉=2% meets national standard.
2. only need during stretching construction manually with torque-indicating wrencg tightly moving nut reach required stretching force.The speedway that is particularly suitable for constructing in the open air, massif, river slope anchoring, the needs of the explosion-proof supporting of coal mine roadway.Need not use original prestress tensioning equipment, solve the inconvenience of former job practices power supply, not explosion-proof, equipment complexity, many, construction complicated problems.
3. satisfied domestic and international demand to this product, filled up this product domestic blank, prestressing technique can have been used, particularly the application of field construction, explosion-proof construction works in more areas.
4. the technology level in the project is that the domestic same industry is the highest, extensively adopts domestic state-of-the-art prestressed anchor production technology.As the technology of colding pressing, Numeric Control Technology, process technology automatically.Improve production efficiency, reduced processing cost.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
