Technical Field
The utility model relates to a strut and use technical field, specifically a reverse wedge type tube slot stock.
Background
At present, in construction roadways such as culverts, mines, subways and the like, a large number of anchor rod supporting modes are adopted to prevent surrounding rocks from falling off and protect the lives of field construction workers. The seam pipe anchor rod is a main part for supporting, and is popular among many users due to convenient use, light weight and convenient mechanical construction. But is constrained in use due to the low anchoring force of the tube-in-tube anchor.
Disclosure of Invention
The utility model discloses solve the technical problem who exists among the prior art to a rational in infrastructure is provided, the consumptive material is few, low in production cost, reduces substantially the back wedge type tube slot stock of the stock of use unit use cost.
The above technical problem of the present invention can be solved by the following technical solutions:
the utility model discloses a reverse wedge type pipe seam stock, including the stock body, the side spaced of the one end of stock body is provided with a plurality of reverse wedges protrudingly, and fender ring and tray are installed in proper order to its other end, the stock body includes outer pole and interior piece, outer pole cross-section one side has the opening, semicircular interior piece is installed respectively to outer pole both sides in the opening, has the space between two interior pieces of opposite side relative with the opening.
Further, the inverted wedge protrusion is disposed at the other side of the outer rod opposite to the opening.
Further, one end of the anchor rod body is a conical anchor rod head.
Further, the end part of the conical anchor rod head is of a two-piece type opening structure.
Further, the inverted wedge protrusions are uniformly arranged in three numbers.
Furthermore, the upper side and the lower side of the cross section of the anchor rod body are also provided with the inverted wedge bulges.
Furthermore, an elastic sheet strip is further arranged in the opening, the outer side of one end of the elastic sheet strip is fixed to one side of the opening of the anchor rod body, and the outer side of the other end of the elastic sheet strip is fixed to the other side of the opening of the anchor rod body.
The utility model discloses the beneficial effect who has does: because the anchor rod adopts a special outer wall structure, the friction force is increased, thereby greatly improving the anchoring force of the anchor rod and meeting and exceeding the anchoring requirements of customers. Therefore, the novel electric heating furnace has the advantages of being reasonable in structure, low in material consumption and production cost, greatly reducing the use cost of a use unit and improving the production efficiency.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a front view of the inverted wedge type tube seam anchor rod of the present invention;
fig. 2 is a top view of the inverted wedge type tube seam anchor rod of the present invention;
FIG. 3 is a cross-sectional view of the inverted wedge type tube seam anchor of the present invention;
fig. 4 is a cross-sectional view of a preferred embodiment inverted wedge slotted anchor of the present invention.
Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
Referring to fig. 1 to 2, the utility model discloses a reverse wedge type pipe seam stock, including stock body 1, the side spaced of the one end of stock body 1 is provided with a plurality of reverse wedge and protrudingly 2, stock body 1 includes outer pole 11 and interior piece 12, outer pole 11 cross-section one side has opening 13, semicircular interior piece 12 is installed respectively to outer pole 11 both sides in opening 13, has space 14 between two interior pieces 12 of the opposite side relative with opening 13, has open elasticity. Because the inverted wedge bulge 2 is arranged, the inverted wedge bulge can be tightly combined with the inner wall of the drilled hole of the rock body, the friction force is increased more strongly, and the reinforced anchoring effect is achieved. The other end of the anchor rod body 1 is sequentially provided with a retaining ring 3 and a tray 4, and the tail part of the inverted wedge type seam pipe anchor rod is provided with the retaining ring 3 welded by adopting an advanced welding process, so that the anchoring force and the rod body strength of the inverted wedge type seam pipe anchor rod are fully exerted. The high bearing capacity tray reduces the weight of the tray by precise design on the premise of meeting the requirement of the bearing capacity of the anchor rod, thereby reducing the labor intensity of installation workers.
In this embodiment, the inverted wedge protrusion 2 is disposed on the other side of the outer rod 11 opposite to the opening 13. The one end of stock body 1 is toper stock head 5, toper stock head tip is two formula open structure, and it can make things convenient for the installation of stock. Preferably, three inverted wedge protrusions 2 are uniformly arranged; different numbers of inverted wedge protrusions 2 can be arranged according to the length of the anchor rod.
After the existing seam tube anchor rod technology is improved, the anchor rod adopts a special outer wall structure, so that the friction coefficient of the seam tube anchor rod is increased, and the effect of improving the anchoring force is achieved. The front end of the inverted wedge type seam pipe anchor rod is a conical anchor rod head, which can facilitate the installation of the anchor rod. This patent has rational in infrastructure, and the consumptive material is few, and low in production cost reduces the use cost of use unit by a wide margin, improves production efficiency's advantage.
In another embodiment of the present invention, the upper and lower sides of the cross section of the anchor rod body 1 are further provided with the inverted wedge protrusions 2. Three sides of the anchor rod body 1 are provided with inverted wedge bulges 2, so that the gripping force is improved. Still be provided with in the opening and play piece strip 6, the one end outside of play piece strip 6 is fixed in stock body 1 open-ended one side, the other end outside of play piece strip 6 is fixed in stock body 1 open-ended opposite side. The elastic strip increases the elasticity of the cross section of the anchor rod body on one hand, and on the other hand can prevent stone particles from entering the interior of the anchor rod body from the side surface.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
