Description
Technical Field
The utility model relates to a construction tool technical field, concretely relates to lock foot stock fixed bolster that punches.
Background
At present, after a tunnel cavern is excavated, the balance state of original surrounding rocks is broken, the surrounding rocks and the vault generate plastic deformation and relaxation, and in order to prevent excessive displacement and deformation of the disturbed surrounding rocks, a reasonable supporting structure is required to bear the pressure of the surrounding rocks. The steel arch is an important component in the primary supporting structure of the weak surrounding rock tunnel and is a part of permanent support. When a steel arch is built, a foot locking anchor rod is usually required to be arranged at a certain angle to play a role in preventing the arch feet of the steel arch from contracting and falling. However, in the current construction, no device for accurately controlling the driving angle exists, and the constructor only relies on the experience of the constructor to drive the foot-locking anchor rod. Therefore, the construction angle is usually larger than the design requirement angle, so that the function of preventing the arch springing from shrinking, which is played by the foot locking anchor rod, is greatly reduced, and potential safety and quality hazards are generated.
SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at solving the technical problem that exists among the prior art, innovated a lock foot stock fixed bolster that punches very much, can unify to beat and establish the angle, guarantee construction safety and quality.
In order to realize the above purpose of the utility model, the utility model provides a punching fixing bracket for a foot locking anchor rod, which comprises two \21274 ' shaped pieces with openings arranged in opposite directions, wherein the two \21274 ' shaped pieces are respectively positioned at two sides of an I-shaped steel and clamp the I-shaped steel through the two \21274 ' shaped pieces; the spacing between the limiting holes of the two \ "21274 \" shaped pieces is different, so that the inclination angles of the foot locking anchor rods on the two sides of the I-shaped steel are different.
In the scheme, the method comprises the following steps: the space between the' 21274.
In the scheme, the method comprises the following steps: the support plate is flush with the support plate on one side, and the structure is compact and clean.
In the scheme, the method comprises the following steps: the v-shaped 21274part is made of profile steel, the abutting plate is made of a steel plate and is welded with the v-shaped 21274part into a whole, the structure is more stable, and the supporting strength is enhanced.
In the scheme, the method comprises the following steps: the thickness ranges of the' 21274part and the supporting plate are both 5-10 mm, so that the supporting strength is guaranteed, and the requirement of supporting a tunnel support is met.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: two \ "21274 \" shaped pieces are arranged and are respectively used for installing foot locking anchor rods positioned at two sides of the I-shaped steel; and two spacing holes for the foot-locking anchor rod to pass are arranged in a staggered manner, so that the foot-locking anchor rod is inserted obliquely, and the installation requirement is met. The gap of the '21274' profile is arranged for clamping the I-shaped steel, and the wing plate at one side is abutted against the abutting plate, so that the I-shaped steel is positioned conveniently. The fixed lock foot stock of this technical scheme is the different planes in space and arranges, and inclination is different, the site operation quality control of being convenient for.
Drawings
The above and/or additional aspects and advantages of the present invention will become apparent and readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
fig. 1 is a cross-sectional view of the present invention;
fig. 2 is a front view of the present invention.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1 and fig. 2, the punching fixing bracket for the foot-locking anchor rod comprises two \21274 "profile pieces 1 with opposite openings. Two '21274' profile pieces 1 are respectively positioned at two sides of the I-shaped steel A, and the I-shaped steel A is clamped by the two '21274' profile pieces 1. A butting plate 2 is connected between the two \ "21274 \" profile parts 1, and the butting plate 2 is used for butting against a side wing plate of the I-shaped steel A. Two support plates 1a which are oppositely arranged on each '21274' profile 1 are respectively provided with a limiting hole 1b for a foot locking anchor rod to pass through, and the two limiting holes 1b of the same '21274' profile 1 are arranged in a staggered way, so that the foot locking anchor rod is obliquely inserted. The spacing between the limiting holes 1b of the two \ "21274 \" profile parts 1 is different, so that the inclination angles of the foot locking anchor rods at the two sides of the I-shaped steel A are different. The spacing between the limiting holes 1b of the two '212741' profile parts is different, so that the inclination angles of the foot locking anchor rods on the two sides of the I-shaped steel A are different, the foot locking anchor rods are arranged in a spatial different plane, and the inclination angles are different, thereby facilitating the control of the field construction quality. Specifically, the limiting hole 1b closer to the abutting plate 2 is higher than the other limiting hole 1b. The '21274', the profile component 1 is made of profile steel, the resisting plate 2 is made of steel plates and is welded with the '21274', and the structural support strength is stronger.
Preferably, the space between the 'v 212741' shaped parts is just equal to the width of an A wing plate of the I-shaped steel, so that a certain clamping force is provided, and the connection is stable. Preferably, the support plate 2 is flush with the support plate 1a on one side, and the structure is compact and neat. Preferably, the two flanges of the i-section a are located between the two support plates 1 a.
Preferably, the thickness ranges of the' 212741 profile and the supporting plate 2 are both 5-10 mm, so that the supporting strength is guaranteed, and the requirement of supporting a tunnel support is met.
When the device is used, the device is clamped on the I-steel A from the lower part of the I-steel A, the two '21274' profile parts 1 are respectively positioned on two sides of the I-steel A, and then the foot locking anchor rods sequentially penetrate through the limiting holes 1b on the same side and are fixed for installation. The angle is established in the unity, satisfies and inserts the slope of lock foot stock, accords with the installation requirement.
