Description
Technical field
The present invention relates to technical field of buildings, particularly relate to the connecting structure of a kind of embedded iron parts and dowel.
Background technology
The reliable connection of embedded iron parts and dowel is requisite in modern construction engineering.At present, embedded iron parts and dowel, especially pile end plate and dowel, pre-embedded steel slab and dowel, the most frequently used method of attachment is welded on embedded iron parts by dowel, a lot of problem is there is: one is the distortion that welding can cause embedded iron parts in welding process, make the air spots of embedded iron parts, difficulty is caused to subsequent construction; Two is weld easily to damage dowel, reduces the tensile strength of dowel, have impact on connection effect; Three is pernicious gases that welding produces, and affects occupational health, is also unfavorable for environmental protection; Four is consumption and costs that welding method not only increases material, also add the site work time, reduces the efficiency of installation.
In prior art, the connection of embedded iron parts and dowel, the particularly connection of pile end plate and dowel, most employing Fig. 1, mode shown in Fig. 2, stake rod member D top is provided with pile end plate B, first one piece of junction plate C is welded on pile end plate B, again dowel A is welded on junction plate, will through twice welding, just can complete the installation work of stake top dowel, and, in Specific construction process, the quantity of junction plate C is no less than 4 pieces, like this, not only time-consuming, consumable material is many, and due to stake top protrude junction plate C, concrete E(cushion cap, base plate or beam) reinforcing bar be difficult to colligation and put in place, if first colligation concrete E(cushion cap, base plate or beam) reinforcing bar, add to the difficulties then to welding dowel.The Site Welding quality of another III grade of steel is difficult to ensure, and junction plate C is different from the steel grade of dowel A, also can affect the effect of welding.
In the connection of embedded iron parts and dowel, the particularly connected mode of pre-embedded steel slab F and dowel A, as shown in Figure 3, usually by position and the dowel diameter of designing requirement, perforate G on pre-embedded steel slab F, then by dowel A implant holes G, the end of dowel A is lower than pre-embedded steel slab F plane certain altitude, weld in the hole G in pre-embedded steel slab F front and around the dowel A at the back side again, the connection of pre-embedded steel slab F and dowel A can be completed.If adopt one-level steel as dowel, see Fig. 4, at pre-embedded steel slab F tapping, dowel A is bent, and be welded on pre-embedded steel slab F.This connected mode of built-in fitting and dowel, mainly contains three shortcomings, and one is increase Site Welding workload, and two is because welding deformation causes built-in fitting air spots, when installation accuracy requires higher, must polish to welding position, time-consumingly takes a lot of work; Three is the welding around dowel, easily causes undercut, and dowel is also different from the steel type of embedded board, causes dowel cross section to diminish, reduces the intensity of dowel.
Summary of the invention
In order to solve the inconvenience that embedded iron parts and the existing welded connection technology of dowel bring, the invention provides the connecting structure of a kind of embedded iron parts and dowel.
Technical scheme of the present invention is achieved in that the connecting structure of a kind of embedded iron parts and dowel, comprise: embedded iron parts, dowel, and described embedded iron parts is the pile end plate being arranged on a Rod end, described pile end plate is provided with tensioning nut, it is characterized in that: described connecting structure also comprises anchor bolt, the outer wall of described anchor bolt is provided with the external screw thread cooperatively interacted with tensioning nut (211), the external screw thread of described anchor bolt is threaded with tensioning nut, the center of described anchor bolt one end, inwardly also internal thread is provided with by end, size and the dowel of described internal thread cooperatively interact, one end of described dowel is provided with the external screw thread with anchor bolt screw-internal thread fit, and dowel is threaded with anchor bolt by external screw thread.
The diameter of described dowel is less than or equal to φ 18mm, and the diameter of described anchor bolt is φ 23mm to φ 33mm, and its length is 25mm to 35mm.
The depth of internal thread of described anchor bolt is 20mm to 30mm.
The diameter of described dowel is greater than φ 18mm, and the diameter of described anchor bolt is φ 27mm to φ 37mm, and its length is 55mm to 65mm.
The depth of internal thread of described anchor bolt is 20mm to 30mm.
