Abstract
The utility model discloses an anchor rod stop device, including two larynx hoops, by the fixed main part that constitutes of two halfbodies butt joints that the structure is the same. The main body comprises a circular cylindrical intermediate body and funnel-shaped buckle covers coaxially arranged with the top and the bottom of the intermediate body, the intermediate body comprises an upper annular limiting steel plate and a lower annular limiting steel plate, and a plurality of longitudinal limiting steel plates are uniformly connected between the upper annular limiting steel plate and the lower annular limiting steel plate at intervals along the vertical direction; the device is adopted to limit the anchor rod, so that the anchor rod can be quickly connected with the anchor rod, and the construction efficiency is greatly improved; in addition, the contact area between the anchor rod and the inner wall of a drilled hole is enlarged due to the longitudinal limiting steel plate and the annular limiting steel plate with certain width, and the anchor rod is not easy to sink into a rock stratum, so that the anchor rod is always positioned in the center of the drilled hole, and the subsequent grouting plumpness is guaranteed.
Description
Technical Field
The utility model relates to a stop device, in particular to stock stop device.
Background
The side slope and foundation pit protection mostly adopt protection such as stock frame roof beam, stock hanging net shotcrete, the stock is the most economic effectual mode in the side slope reinforcement, it is effectual to have a supporting effect, easy and simple to handle, use nimble, occupy the advantage that the construction space is few, its theory of action is that stock one end is inserted in the steady rock mass within the side slope glide plane along the hole that has bored, protective structure thing such as the other end and domatic beyond frame roof beam are connected, strengthen the adhesion force of stock and rock mass in order to resist the sliding force of slope body through to downthehole cement mortar injection. The bond strength of the anchor rod and the rock mass is critically dependent on the full degree of mortar around the anchor rod, and the anchor rod is fixed by a triangular limiting rib formed by welding HPB300 phi 6 and phi 10 steel bars in the industry at present. On one hand, the method has low efficiency and consumes manpower; on the other hand, after the anchor rod welded by the limiting ribs is inserted into the drilled hole, the limiting ribs are thin, and in addition, under the action of the gravity of the anchor rod, the limiting ribs are easily pressed into a soil body, particularly into a soft rock stratum, so that mortar is not fully injected into the contact side of the anchor rod and the rock stratum of the hole wall of the drilled hole, the protection effect of the anchor rod is influenced, and potential safety hazards are left for subsequent work.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide a quick connection with an anchor rod, thereby improving the construction efficiency; and can let the stock be located the drilling center all the time, guarantee the stock stop device of follow-up slip casting plumpness.
The utility model discloses an anchor rod limiting device, which comprises a main body formed by butt joint and fixation of two half bodies with the same structure, wherein the main body comprises an intermediate body, the top and the bottom of the intermediate body are sequentially connected with buckle covers which are coaxially arranged with the intermediate body, the intermediate body is of a circular cylinder structure and comprises an upper annular limiting steel plate and a lower annular limiting steel plate, and a plurality of longitudinal limiting steel plates are uniformly connected between the upper annular limiting steel plate and the lower annular limiting steel plate at intervals along the vertical direction;
the buckle closure be the infundibulate structure, the infundibulate structure include circular cone frustum shape neck and the circular cylindrical end that links to each other with circular cone frustum shape neck, the diameter main aspects of circular cone frustum shape neck and the fixed linking to each other of corresponding hoop spacing steel sheet circular cone frustum shape neck the wall on interval 180 degrees open and have two trapezoidal holes, the internal diameter of circular cylindrical end unanimous with the stock diameter of treating to pass, two semicircular cylindrical ends that the butt joint constitutes circular cylindrical end are through the hoop card of the larynx of hoop cover on two semicircular cylindrical ends along the hoop solid together.
The utility model discloses compare with current utility model, the utility model has the advantages of it is following:
the device can be quickly connected with the anchor rod, so that the installation and construction efficiency of the limiter is greatly improved; in addition, the contact area between the anchor rod and the inner wall of a drilled hole is enlarged due to the longitudinal limiting steel plate and the annular limiting steel plate with certain width, and the anchor rod is not easy to sink into a rock stratum, so that the anchor rod is always positioned in the center of the drilled hole, and the subsequent grouting plumpness is guaranteed.
Drawings
Fig. 1 is a front view of an anchor rod limiting device of the present invention;
FIG. 2 is a side view of one half of the device shown in FIG. 1;
FIG. 3 is a perspective view of the device shown in FIG. 1;
fig. 4 is a schematic view of the apparatus shown in fig. 1 in a use state.
The specific implementation mode is as follows:
the following detailed description of the present invention will be made with reference to the accompanying drawings and specific embodiments.
As shown in the drawings the utility model discloses an anchor rod stop device, include the fixed main part that constitutes of butt joint of two halfbodies the same by the structure, the main part include midbody 2 the top and the bottom of midbody all have connected gradually with buckle closure 1 that the midbody coaxial line set up, the midbody be the cylinder shape structure of ring, the midbody include two upper and lower hoop spacing steel sheets 5 between have a plurality of vertical spacing steel sheets 6 along the even interval connection of vertical direction, the number of preferred vertical spacing steel sheet is four, so both make anchor rod and the drilling inner wall area of contact grow, avoid the increase in cost again.
Two semicircular cylindrical ends which form the circular cylindrical ends in a butt joint mode are clamped and fixed together through the hose clamp 3 which is sleeved on the two semicircular cylindrical ends along the circular direction.
The working principle is as follows: the two half bodies are aligned and folded at a set position on the anchor rod 4, the anchor rod 4 penetrates through the buckle cover 1, the throat hoop 3 is used for locking the circular cylindrical end of the buckle cover 1 in the circumferential direction, the anchor rod 4 and the limiting device are fixed, and similarly, another limiting device is arranged on the anchor rod 4 at a certain interval until the limiting device on one anchor rod is completely arranged. Compared with the existing welding limit reinforcing steel bar in the industry, the construction efficiency is greatly improved; in addition, four longitudinal limiting steel plates 6 and two annular limiting steel plates 5 with certain width, strength and rigidity are arranged on the anchor rod limiting device after installation is completed, so that the contact area of the anchor rod and the inner wall of a drilled hole is increased, the anchor rod 4 is always positioned in the center of the drilled hole, and the subsequent grouting fullness is guaranteed.
