Abstract
The utility model relates to a combined through-wall bolt which belongs to the details of the auxiliary apparatus of the building industry. The utility model is put forward in order to overcome that the traditional integral through-wall bolt has the disadvantages of time consuming, labor consuming, material wasting and insufficient strength. Bolts are used as three sections, rolling and pressing threads are arranged on the surface of the bolt, and the bolts are connected through connecting nuts; a waterproof board is arranged in the middle part of a middle bolt, and a fastening nut, a backing board and a waterproof conical block are arranged at the bolts of both ends. When the utility model is used, the well-connected through-wall bolts are pre-embedded in walls; after the utility model is used, the bolts of the both ends are detached for using next time. The utility model has the advantages of time-saving and labor-saving operation, good rigidity and strength, reliable use, and material saving, and the cost can be obviously reduced.
Description
The utility model belongs to the parts in the employed supplementary equipment of building industry, and it is specifically related to a kind of structure of improved through-wall bolt.
This through-wall bolt is reinforced gang form and is used in the operation of construction cast concrete, it will guarantee the firm and stable of template assembly from intensity.Traditional through-wall bolt is an one, has the fine thread of mechanism on its surface, and in use, because threaded tip is sharp, screw thread very easily is bruised, and gives in the construction to make troubles; The two ends of through-wall bolt will be exposed at outside the wall, its exposed portions must be cut off after using, and fill in the cave with cement again, and the part that is cut off then causes waste, but also has expended many man-hours.In addition, on waterproof problem, also can not handle finely always.
The purpose of this utility model is that the spy proposes new departure of knockdown through-wall bolt in order to solve the problem of the through-wall bolt existence in the prior art, and it has energy saving of labor, material-saving, raises the efficiency the characteristics that reduce cost.
By as above design, the knockdown through-wall bolt that this programme provided includes bolt, backing plate and tightening nut, its concrete feature is: its bolt is formed by three sections, have the identical rolled thread of Dimensions on their surface, length of bolt is less than the thickness of body of wall in the middle of it, coupling nut in the connection place of middle bolt and bolts at two ends with tubular links, and the plastics taper that is provided with two inner waterproofings outside coupling nut is stifled.
In this programme, can weld a seal plate in the middle of the bolt in stage casing, this seal plate can be square, circle or polygon, the axis normal of its plate face and bolt, the weld seam between bolt and the seal plate should be tight.Screw thread on its bolt is square threaded form or trapezoidal thread.
Adopt this programme can embody following superiority: 1. the bolt of this combined type through-wall bolt is three sections and combines, intermediate section is done in body of wall, the bolt that connects two ends through coupling nut extends to outside the body of wall, through-wall bolt with original form during use is identical, after using up, the bolt at two ends is laid down, and remove the waterproof taper is stifled, with cement the cave is filled and led up, its operation is very simple, can save man-hour significantly; The bolt at the two ends of 2. unloading can next time usefulness again, can save a large amount of metallic material and reduce cost; 3. the thread surface of this bolt makes the square threaded form or the trapezoidal thread of roll extrusion, and so the bolt of processing all has improvement greatly on rigidity and intensity, and reliability is obviously improved; 4. increased seal plate at the middle part of middle bolt, can be guaranteed, the reliability of using also has been very helpful water-proof function; 5. its simple in structure, low cost of manufacture is suitable for making in batches promoting the use of.
Fig. 1 is the structural representation of this programme combined type through-wall bolt.
The embodiment of existing accompanying drawings this programme.It is the improvement to the through-wall bolt of traditional form, it makes all-in-one-piece bolt three sections combination, welded a seal plate 6 in the centre of middle bolt 7, weld seam between the two should be tight, connect with coupling nut 5 between middle bolt and the bolts at two ends 1, tightening nut 2 and backing plate 3 are arranged on bolts at two ends, between backing plate and coupling nut, also have a waterproof plastic taper stifled 4.During use, the through-wall bolt that combines is embedded in the body of wall, because the length of middle bolt is less than the thickness of body of wall, all stay within the metope so the waterproof taper at two coupling nuts and two ends is stifled, bolt with two ends after the use unloads, and with the stifled taking-up of taper, then two coupling nuts are all stayed within the walls, mend the stifled formed cave of taper with cement again, so just finished using and operating it.The pilot sample of this programme is through experiment operation proof, and it has: operate characteristics time saving and energy saving, that the high use of stiffness and strength reliable, the energy economical with materials reduces cost significantly, be suitable for making and promoting the use of in batches.
