Abstract
The utility model relates to a full-thread grouted rock bolt, which comprises a solid rock bolt rod body, an anchor bolt, a backing board and a nut, wherein a full-length continuous single-head screw is arranged on the solid rock bolt rod body, which is a standard screw whose tooth type is a triangle, a ladder type or a saw tooth type or the tooth type is a wave-shaped non-standard screw. The utility model has the advantages of lower production cost, which can be cut at random according to on-site requirements or can be lengthened through a connecting sleeve, is convenient for mounting the nut and various anchor heads, is convenient for prestress construction, and satisfies the requirements of construction site.
Description
Technical field
The utility model relates to anchor pole, and particularly the solid anchor pole of full thread is made the field.
Background technology
Existing grouting rock bolt mainly is made of solid anchor rod body, and usually accessories such as anchor head and nut can't be installed.Solid anchor rod body adopts concrete to help reinforcing bar (GB1499-1998) with hot rail band usually, under the particularity situation, in order to be connected with the adapter sleeve spiral with nut, also has directly to process external screw thread at steel bar end, then sacrifices the performance of reinforcing bar.Also have this reinforcing bar one end jumping-up, and process external screw thread, match with internal thread with nut at this end.As, Chinese patent literature ZL01276982.7 has corresponding disclosure to this.This kind band helps reinforcing bar to use as solid anchor rod body, and the lower advantage of material cost is arranged, and uses inconvenience but exist, can not be according to the defective of any cutting of on-the-spot needs.And existing finish rolling deformed bar (indented bars GB/T20065-2006 for prestressed concrete) has discontinuous external screw thread on it, has the manufacturing process complexity, the shortcoming that cost is higher.
The utility model content
The purpose of this utility model provides a kind of cost grouting rock bolt lower, easy to use.
This novel purpose is achieved in that a kind of full thread grouting rock bolt, comprise solid anchor rod body, anchor head, backing plate and nut, this solid anchor rod body is provided with the continuous one start screw of total length, and it is that tooth form is triangle, trapezoidal or zigzag standard thread or odd-pitch screw.
Adopt the total length continuous thread,, and can be connected with nut and all kinds of anchor heads and adapter sleeve (lengthening with) spiral with convenient cutting arbitrarily.
Compared with prior art, this novelly has a following beneficial effect:
1, anchor rod body is provided with the total length connecting thread, is convenient to any cutting, to satisfy the job site needs.
2, the convenient accessories such as nut and all kinds of anchor heads of installing help applying prestressing force in case of necessity.
3, continuous (standard or non-standard) screw thread that adopts the tooth height not wait on the body of rod, after the slip casting, nut and anchor rod body spin the high lower of tooth at position will be fixed for slurry placement, thereby make nut can not take place to become flexible on anchor rod body because of being subjected to external force again.Therefore, the fastness and the globality of having strengthened member of structure have been improved.
4, the convenient connection.Adopt the internal thread at adapter sleeve two ends easily two anchor rod body spirals to be connected, with the lengthening anchor rod body.Compare with existing welding lengthening technology, have higher reliability.
Description of drawings
Fig. 1 is this novel structure chart;
Fig. 2 is the structure chart (triangle thread) of the another embodiment of solid anchor rod body shown in Figure 1;
Fig. 3 is that Fig. 4 Fig. 5 is respectively the structure chart (being respectively trapezoidal thread, saw-tooth thread and corrugated thread) of other three embodiment of solid anchor rod body shown in Figure 1.
The specific embodiment
Fig. 1 illustrates, and this new type mortar anchor pole is made up of anchor head 1, solid anchor rod body 2, stop grouting plug 3, backing plate 4 and nut 5.Material is that the solid anchor rod body of carbon steel or low-alloy steel is provided with the continuous one start screw of total length, and its tooth form is the standard thread or the odd-pitch screw of triangle (Fig. 2), trapezoidal (Fig. 3) or zigzag (Fig. 3).The tooth form of odd-pitch screw is the continuous thread that waveform (Fig. 5) or tooth height do not wait, as, be that continuous (standard or the non-standard) screw thread of processing forms the continuous thread that the tooth height does not wait on the oval reinforcing bar at section.Left-handed or the right-handed thread of the general employing of screw thread.Solid anchor rod body surface is provided with the concave-convex decorative pattern.Also has the adapter sleeve (not shown) that is connected with two solid anchor rod body spirals.Anchor head can be adopted as the expansion shell type anchor head.
