Description

Precise alignment finish rolling threaded die for steel box girder installation consolidation pier construction

Technical Field

The utility model relates to a construction facility, the accurate counterpoint mould that uses in concretely relates to steel case roof beam installation consolidation pier construction.

Background

In the building construction, the positioning and installation of the steel bars are always the key problems in the engineering construction, in the traditional steel bar construction, most of the steel bars are bound or welded after being positioned, the pier column and the steel beam are welded, namely, a support and a leveling steel plate are arranged on the pier column cushion stone, and the leveling steel plate and the steel beam are welded into a whole.

In the construction engineering, the connection form of the pier column and the steel box girder is that the pier beam is fixedly connected, 5 meters above the pier column, and the outer wrapping steel plate (namely the steel ferrule) is provided with the shear nails and the stiffening plates. The pier column is internally provided with 24 phi 32 finish rolling screw threads and vertical tensioning ribs, the tensioning ribs penetrate through a reserved hole at the bottom of the beam when the steel box girder is installed, after the steel beam is installed, concrete is poured in the box and 5 meters above the pier column at one time to form pier girder consolidation, and after the concrete strength meets the requirement of vertical tensioning.

In the construction of the finish rolling threaded steel bar high altitude pair for box girder bottom plate preformed hole, the prior art is that after the girder steel high altitude is tentatively counterpointed, 10cm space is reserved with the reinforcing bar at the bottom of the beam, then the steel pipe is used to stretch out in the beam bottom plate preformed hole by the manual work, embolias the reinforcing bar one by one, and after 24 finish rolling threads are all emboliaed the steel pipe, the accurate position that falls is accomplished in the girder steel whereabouts. The construction personnel using the method have potential safety hazards, and in addition, the high-altitude phi 32 finish rolling twisted steel has the problems of elastic deformation and the like, so the manual operation difficulty is high.

SUMMERY OF THE UTILITY MODEL

The utility model provides a steel case roof beam installation consolidation mound construction accurate alignment finish rolling screw thread mould, it has solved finish rolling twisted steel high altitude to in being the construction of case roof beam bottom plate preformed hole, and there is the potential safety hazard in the construction operation personnel, the big scheduling problem of the manual work operation degree of difficulty.

In order to solve the above problem, the utility model adopts the following technical scheme: the precise alignment finish rolling threaded die for the construction of the steel box girder installation consolidation piers is composed of an embedding sleeve and an embedding sleeve, wherein the embedding sleeve is fixed below a steel girder bottom plate, the upper part of the embedding sleeve is embedded in the lower part of the embedding sleeve, square pipes are longitudinally and transversely arranged in the embedding sleeve, and the upper end of a finish rolling threaded steel bar is arranged in the staggered area of each pair of the longitudinally and transversely arranged square pipes.

The utility model can quickly complete the high-altitude alignment of the reinforcing steel bar, reduce the time of manual operation and ensure the safety of high-altitude operation; the method also has the advantages of simple raw material processing and manufacturing, simple operation, easy control and convenient use. The utility model discloses a characteristics are embedded cover of inlaying for the main part, adopt the square pipe of setting with great ease fixed with the finish rolling twisted steel, once can accomplish whole reinforcing bars to the hole problem to the counterpoint.

Detailed Description

The present invention will be described in detail with reference to the preferred embodiments.

As shown in fig. 1-5, the precise alignment finish rolling threaded die for the construction of the steel box girder installation and consolidation piers is composed of an embedding sleeve 1 and an embedding sleeve 2, wherein the embedding sleeve 1 and the embedding sleeve 2 are both in square frame structures, and the embedding sleeve 1 and the embedding sleeve 2 are welded by 10mm steel plates. The embedding sleeve 1 is fixed below the steel beam bottom plate 4, the upper portion of the embedding sleeve 2 is embedded in the lower portion of the embedding sleeve 1, square pipes 2-1 are longitudinally and transversely arranged in the embedding sleeve 2, every two square pipes 2-1 are a pair, the front ends and the rear ends of a plurality of pairs of vertically arranged square pipes 2-1 are fixed on the front frame and the rear frame of the embedding sleeve 2, the left ends and the right ends of a plurality of pairs of horizontally arranged square pipes 2-1 are fixed on the left frame and the right frame of the embedding sleeve 2, holes are formed in the frames of the embedding sleeve 2. The upper end of the finish rolling twisted steel 3 is arranged in a square area at the staggered position of each pair of the square pipes 2-1 which are arranged longitudinally and transversely.

The mold designed this time is composed of an embedded nest plate and a lower nest:

(1) embedding a sleeve: the embedded sleeve and the lower embedded sleeve are welded by a 10mm steel plate.

(2) And a 10-by-10 square tube is added into the lower nest for fixing the finish-rolled twisted steel.

The current manual work is to the hole, and the girder steel high altitude hover time is long, has great potential safety hazard, the utility model discloses reasonable effectual this problem of having solved. And the embedded embedding sleeve can be repeatedly used, so that the precision and the efficiency are improved, and the equipment cost of occupying a large crane for a long time is reduced.

The upper part is embedded with a sleeve and welded on the outer side of the steel beam bottom plate; the lower nest is placed over the rebar during use. And phi 32 finish rolling the twisted steel, and when the lower part of the twisted steel is placed in the lower part nest, the height of the steel does not exceed the upper edge of the lower part nest. The steel beam bottom plate, this picture is that the reinforcing bar accomplishes the counterpoint through the embedding steel sheet.

The utility model discloses obtain using in the experimental items, this utility model has replaced original artifical reinforcing bar counterpoint mode in the construction, very big quickening construction speed, the material resources of using manpower sparingly use moreover the utility model discloses the potential safety hazard of artifical high altitude construction of avoiding, the satisfactory completion construction task in this engineering.
