Abstract
The invention discloses a steel beam fixing device which comprises two pre-burying poring devices, wherein the two pre-burying poring devices are symmetrically arranged at an interval in a floor; each pre-burying poring device comprises a casing and a casing base; the casing bases are pre-buried in a floor structure; the casings are perpendicular to the floor and are mounted on the casing bases; threaded parts of U-shaped anchor bolts respectively and sequentially penetrate through pressing plates of two through holes, the casings and the casing bases; screw nuts are screwed into the threaded parts from the lower surface of the floor so as to fix a steel beam on the floor; the distance between the two through holes is equal to that of the two pre-burying poring devices. The casing bases of the steel beam fixing device ensure that the casings are constantly perpendicular to the floor and are not tilted or inclined when being pre-buried; construction security can be ensured as the steel beam fixing device is convenient to mount and dismount and stable to connect; materials can be saved as the steel beam fixing device can be used repeatedly; moreover the labor is greatly saved, and the working efficiency is improved.
Description
Technical field
The present invention relates to a kind of steel beam fixing device, belong to building structure technology field.
Background technology
Recent two decades comes, and along with developing rapidly of China's building trade, building structure advances towards higher, more complicated form, and high level, irregular building structure are increasing, and overhanging scaffold ensures often and the necessary requirement of its smooth construction makes consumption huge. Wherein, in builder's jack, the anchoring of girder steel is again the key ensureing builder's jack safety. At present, the anchoring process of most traditional builder's jack girder steels mostly is and adopts crab-bolt cast-in-place among concrete floor. Crab-bolt can only single use, and use complete after also to take a lot of work the Partial Resection beyond floor. The method not only wastes great deal of steel, and a large amount of human and material resources are also wasted in the excision of unnecessary crab-bolt.
Summary of the invention
For above-mentioned prior art Problems existing, it is an object of the invention to provide a kind of stable connection, it is possible to repeatedly use, crab-bolt is installed simple, removes convenient steel beam fixing device.
For achieving the above object, the technical solution used in the present invention is: a kind of steel beam fixing device, two pre-buried hole-forming devices in floor it are symmetricly set on including interval, described pre-buried hole-forming device includes a sleeve pipe and a sleeve pipe base, described sleeve pipe base is embedded in floor construction in advance, described sleeve pipe is perpendicular to floor and is arranged on sleeve pipe base, the threaded portion of U-shaped crab-bolt is respectively successively from the pressing plate of reserved two through holes, sleeve pipe and the traverse of sleeve pipe base, nut is from screw-in threaded portion, underfloor surface, girder steel is fixed on floor, distance between said two through hole is equal to the distance between pre-buried hole-forming device.
Preferably, described sleeve pipe is PVC sleeve pipe.
Preferably, described PVC sleeve pipe surfaces externally and internally is coarse.
The sleeve pipe base of the present invention ensure that sleeve pipe is perpendicular to floor all the time, and will not skew time pre-buried inclination; Installation and removal are convenient, stable connection, it is possible to ensure construction safety; Can repeatedly use, save material, and significantly saved labour, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
In figure, 1. sleeve pipe, 2. sleeve pipe base, 3. floor, 4.U shape crab-bolt, 5. pressing plate, 6. girder steel, 7. nut.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, a kind of steel beam fixing device, two pre-buried hole-forming devices in floor it are symmetricly set on including interval, described pre-buried hole-forming device includes a sleeve pipe 1 and a sleeve pipe base 2, described sleeve pipe base 2 is embedded in floor 3 structure in advance, described sleeve pipe 1 is perpendicular to floor 3 and is arranged on sleeve pipe base 2, the threaded portion of U-shaped crab-bolt 4 is respectively successively from the pressing plate 5 being provided with through hole, sleeve pipe 1 and sleeve pipe base 2 pass, nut 7 screws in from U-shaped crab-bolt 4 threaded portion, girder steel 6 is fixed on floor 3, distance between two through holes is equal to the distance between pre-buried hole-forming device.
Preferably, described sleeve pipe 1 is PVC sleeve pipe.
Preferably, in order to ensure to combine closely between PVC sleeve pipe and surrounding concrete, described PVC sleeve pipe surfaces externally and internally is coarse.
After concrete floor bed die is installed, before concreting, two pre-buried hole-forming devices are fixed on the anchorage point place of builder's jack girder steel, form two pore-formings being perpendicular to floor 3, during installation, the threaded portion of U-shaped crab-bolt 4 is respectively successively from the reserved pressing plate 5 of two through holes, sleeve pipe 1 and sleeve pipe base 2 traverse, then is screwed in from U-shaped crab-bolt 4 threaded portion by nut 7 and can be fixed on floor 3 by girder steel 6. When building completion needs dismounting scaffold, reversely being screwed out by nut 7, extract U-shaped crab-bolt 4, pre-buried hole-forming device is embedded in floor 3 and does not take out. U-shaped crab-bolt 4 adopts pea gravel concreten grout closely knit after removing, owing to PVC internal surface of casing is coarse, it is possible to combine closely with the pea gravel concreten poured into, thus the damage that concrete floor is caused reaches minimum. This device convenient disassembly, it is possible to repeatedly use, saves material; Unnecessary part need not be excised, saved manpower and materials.
