Abstract
The utility model relates to a fastening bolt with an expansible body, an expansion pipe is directly arranged on a fastening bar, the integral construction has no threads, thus the production cost is greatly reduced; an expansion bolt is independent of the fastening bar body, during the construction, the expansion bolt is wedged into the expansion pipe from the outside of the fastening bar, and therefore the construction quality can be ensured.
Description
Technical field:
The present invention relates to a kind of fastening articles for use, especially this volumetric expansion fastening bolt.
Background technique:
The EXPANSION ANCHOR BOLTS of current widespread usage; All cooperate expansion bolt three parts to form by expansion tube and screw rod; Expansion bolt is placed oneself in the midst of in the expansion tube; Advance expansion bolt to impel the mouth of pipe of expansion tube to open by the screw rod rotation, so often take place to can not receive the effect of EXPANSION ANCHOR BOLTS because of screw rod can't advance the open problem of the mouth of pipe that puts in place and can not make expansion tube with expansion bolt.Secondly; Because expansion bolt receives the limitation of expansion tube internal diameter; Short Zhang Chengdu to expansion tube is limited, thus when application and construction in order to ensure fastening effect, must the diameter of mounting hole be broken into equally big with the external diameter of expansion tube; This has just increased the installation difficulty, and the situation of screw rod even the whole damage of EXPANSION ANCHOR BOLTS takes place through regular meeting.Again secondly, be that screw rod can withdraw from easily, is easy to cause some valuable fastened members to lose through screw thread combination use because of screw rod and expansion tube.
Summary of the invention:
In order to eliminate existing both defectiveness with EXPANSION ANCHOR BOLTS, the present invention provides a kind of volumetric expansion fastening bolt, it is characterized in that expansion tube directly be arranged at the anchorage bar main body following, and that expansion bolt accompany anchorage bar is external.The present invention implements in order to following method: 1, make the anchorage bar main body with steel, the higher authorities of bar are that following of bar directly is provided with expansion tube, is carved with some breaches on the expansion tube wall than the body of rod footpath mouthful appropriate round cap that amplifies; 2, make expansion bolt with steel, key is a truncated cone shape, and the bottom surface diameter is equal to the body of rod footpath mouth of anchorage bar; 3, during application and construction with expansion bolt insert in implement in the mounting hole that can insert fastener in following expansion tube mouth of pipe place of anchorage bar fastening.Usefulness of the present invention has: 1, expansion tube and anchorage bar are the same body of rod, need not scribe screw thread, can reduce cost; 2, the internal diameter that can appropriateness during application and construction strengthens mounting hole is to alleviate difficulty of construction; In case 3 installing and locating just can't be moving more easily, can ensure the safety of valuable fastener.
Description of drawings:
Fig. 1 is the anchorage bar schematic appearance; Fig. 2 is the expansion bolt schematic appearance; Fig. 3 is the vertical profile schematic representation of Fig. 2; Fig. 4 is the vertical profile schematic representation of Fig. 1; Fig. 5 uses standby condition vertical profile schematic representation for the present invention; Fig. 6 is an application state schematic representation of the present invention.Among the figure: the 1st, anchorage bar mobile jib, the 2nd, the expansion mouth of pipe, the 3rd, expansion tube inner chamber.
Embodiment:
As shown in Figure 5; Earlier Fig. 2, expansion bolt shown in Figure 3 are injected in the expansion mouth of pipe (2) shown in Figure 1; Can put into the mounting hole of fastener; Beat anchorage bar mobile jib (1) the higher authorities' round cap this volumetric expansion fastening bolt integral body is squeezed in the mounting hole, make in the expansion bolt wedging expansion tube inner chamber (3), the expansion mouth of pipe is opened.
Claims (1)
1. this volumetric expansion fastening bolt, it is characterized in that expansion tube directly be arranged at the anchorage bar main body following.
