Abstract

The utility model relates to a mechanical anchor bolt with chemical agent, which comprises an anchor rod, an expansion sleeve and a propelling sleeve. An expansion cone is arranged at the end of the anchor rod, the expansion sleeve and the propelling sleeve are sleeved on the anchor rod, open grooves circumferentially distributed are disposed on a pipe wall at one end of the expansion sleeve close to the expansion cone, a chemical agent storage chamber is arranged between the inner wall at one end of the expansion sleeve far away from the expansion cone, and the anchor rod, and the chemical agent capable of being squeezed out of the opening grooves of the expansion sleeve is loaded in the storage chamber. The mechanical anchor bolt with the chemical agent integrates advantages of a chemical anchor bolt and a mechanical anchor bolt, and is more stable in performance, higher in anchor force, firmer in installation and wider in application range.

Description

The mechanical anchor that has chemical agent
Technical field
The utility model relates to a kind of mechanical anchor, especially relates to a kind of mechanical anchor that has chemical agent.
Background technique
Crab-bolt is an anchoring piece commonly used in the construction industry.Common expansion anchor is a mechanical anchor, comprises anchor pole, expansion sleeve and advances cover, and during use, deformation or spreading take place expansion sleeve under external force, thereby contacts and compress to realize anchoring with the installation hole wall.But because concrete allows 5% empty paddy usually, perhaps allow the crack in the 0.3mm, when running into sky paddy and crack, the anchorage effect of this expansion anchor will reduce, and have the not firm risk of certain anchoring.
Chemical anchor bolts are by special chemical bonding agent, the screw rod gluing are fixed in the boring of concrete base material, to realize the composite members to the fixed block anchoring.Because the chemical reagent of adorning in its glass tube is inflammable and explosive, so producer must could produce through the approval of national departments concerned, whole process of production needs strict safety, and the production line production isolated fully of use and staff.If it is not only violated national pertinent regulations, and abnormally dangerous by handwork.The antidetonation fireproof performance is very poor.
Summary of the invention
The purpose of this utility model provides the mechanical anchor that a kind of anchoring effect better has chemical agent.
For reaching above-mentioned purpose, the utility model has adopted following technological scheme:
A kind of mechanical anchor that has chemical agent, comprise that the end is provided with the anchor pole of expansion cone, is set in the expansion sleeve on the anchor pole and advances cover, expansion sleeve closes on the tube wall of expansion cone one end and has circumferential opening slot, wherein, expansion sleeve is away from being provided with the chemical agent apotheca between the inwall of expansion cone one end and the anchor pole, but the chemical agent that squeezes out in the opening slot of installing self-expanding cover in the apotheca.
The utility model also can further be realized by following scheme:
The described mechanical anchor that has chemical agent wherein, is placed tubular sealing plastic bag in the described apotheca, chemical agent is loaded in the plastic bag.
The described mechanical anchor that has chemical agent wherein, is offered a plurality of blind holes on the described plastic bag.
The described mechanical anchor that has chemical agent, wherein, described propelling cover is made up of preceding promotion part and promotion part, back; The length of preceding promotion part is less than the length of apotheca, and the external diameter of preceding promotion part is greater than the internal diameter of apotheca, less than the external diameter of apotheca; The internal diameter of back promotion part is more than or equal to the external diameter of apotheca, less than the external diameter of expansion sleeve away from expansion cone one end.
The described mechanical anchor that has chemical agent, wherein, described chemical agent is a construction structure glue.
The mechanical anchor that has chemical agent of the present utility model, during use, crab-bolt is positioned in the pre-drilled cavity, promote to advance cover to move radially by external force, advance the preceding promotion part of cover to enter the chemical agent in the extruding apotheca in the apotheca, the expansion sleeve of promotion part promotion then integral body moves to the expansion cone direction, opening slot on the expansion sleeve is opened, chemical agent flows out in opening slot, empty paddy or crack in effective fill concrete, thereby it is more firm to make that crab-bolt combines with concrete, and anchor force is stronger, installs more firm.Simultaneously used construction structure glue, stable performance, fireproof performance is preferable, therefore can be used on the railway and uses, and using scope is wider.
Description of drawings
Fig. 1 the utility model has the structural representation of the mechanical anchor of chemical agent.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of mechanical anchor that has chemical agent comprises that the end is provided with the anchor pole 7 of expansion cone 1, expansion sleeve 2 and advances cover 4, packing ring 5 and nut 6; Expansion sleeve 2 comprises bulge 21 and joint 22.Bulge 21 closes on expansion cone 1, and bulge 21 tube walls are offered a plurality of opening slots that along the circumferential direction distribute.Be provided with chemical agent apotheca 3 between joint 22 inwalls of expansion sleeve 2 and the anchor pole 7, apotheca 3 is tubular, but the chemical agent 8 that squeezes out in the opening slot of installing self-expanding cover in it.These chemical agent 8 best construction structure glues that adopt.
For better storage of chemical agent, can in apotheca 3, place tubular sealing plastic bag, chemical agent is loaded in the plastic bag.Also can on plastic bag, offer a plurality of blind holes simultaneously, so that chemical agent can be extruded fast when extruding in plastic bag.
Advance cover 4 to form by preceding promotion part 41 and promotion part 42, back; The length of preceding promotion part 41 is less than the length of apotheca 3, and the external diameter of preceding promotion part 41 is greater than the internal diameter of apotheca 3, less than the external diameter of apotheca 3; The internal diameter of back promotion part 42 is more than or equal to the external diameter of apotheca 3, less than the external diameter of expansion sleeve 2 joints 22.
The mechanical anchor that has chemical agent of the present utility model, during use, crab-bolt is positioned in the pre-drilled cavity, press down propelling cover 4 by external force, it is moved radially along anchor pole 1, advance the preceding promotion part 41 of cover 4 to enter the construction structure glue in the extruding apotheca 3 in the apotheca 3, then the joint 22 of promotion part 42 promotion expansion sleeves 2 makes expansion sleeve 2 integral body move to expansion cone 1 direction, opening slot on the bulge 21 of expansion sleeve 2 is opened, chemical agent flows out in opening slot, fill empty paddy or crack in the surrounding concrete, thereby it is more firm to make that crab-bolt combines with concrete, anchor force is stronger, installs more firm.Can be used on the railway and use, using scope is wider.
The above is preferred embodiment of the present utility model only, is not that the utility model is done any pro forma qualification.Any change that is equal to, modification or differentiation etc. that all those skilled in the art utilize the technical solution of the utility model that the foregoing description is made all still belong in the scope of the technical solution of the utility model.
