Abstract
The utility model relates to a combined wall bolt for cast-in-situ concrete formwork comprising a wall-through screw in the middle, fixing screws at the two ends, positioning caps which link the wall-through screw and the fixing screws at the two ends coaxially. External threads are machined at the two ends of each screw, the positioning cap is a taper step, and axial threaded holes are machined at the middles of the two surfaces. The bolts are connected together through the positioning taps whose smaller surfaces face in. Because the utility model is composed of three segments, the middle wall-through screw remains in the wall permanently as conventional ways after construction without the influence on structure performance, while the fixing screws at the two ends are detachable and can be used repeatedly, consequently, the utility model also has the advantages of steel-saving, no cutting cost on the protruding part from the wall, bigger saving on construction investment and cost.
Description
Technical field
The utility model relates to a kind of builing industry construction and uses accessory, relates in particular to a kind of Cast-in-place concrete template through-wall bolt.
Background technology
In the builing industry building Cast-in-place concrete site operation, template needs fastening.It is fastening and stable with template that mode at present commonly used is that the screw rod through walls with a long one fills up the lumps of wood and the steel pipe established outward by template.After the construction, screw rod exposes on the metope, must cut off one by one.The problem that this mode is brought is as follows: at first, needs to drop into a large amount of finished steel processing screw rods, and also disposable use, brought a large amount of wastes, increased construction cost; In addition, cut off one by one, except increasing operation, also will increase the instrument of cutting, material and artificial input, this has also increased construction cost; Be exactly in addition, when stripping,, need play the delivery plate, the hurt of template is relatively gone through evil, badly influenced the application life of template with modes such as prizing, pound owing to exist very big adhesion between template and metope and the screw rod through walls.
The utility model content
At the problems referred to above, the purpose of this utility model is to provide a kind of Cast-in-place concrete template combined type through-wall bolt, reducing the waste of through-wall bolt as far as possible, and is convenient to retracting of on-the-spot template.
For realizing above-mentioned task, the technical solution of the utility model is: a kind of Cast-in-place concrete template combined type through-wall bolt, this bolt is made of the standing screw at the screw rod through walls of centre and two ends thereof and the spacing plug that links together in order to the standing screw coaxial line with the screw rod through walls of centre and two ends, the both ends of each screw rod all are processed with external screw thread, spacing plug is the taper type structure, the centre of two table tops of taper type plug is processed with the screw of axis direction, each screw rod links together by taper plug spiral successively, and the little table top of two taper plugs assembles inwardly.
On the middle body of rod of centre screw rod through walls, be fixed with seal plate.
In the screw arranged around at least two dismounting grooves are arranged on the big table top outwardly of described taper plug.
On the body of rod at the two ends position of centre screw rod through walls, be fixed with the axial screw-in size of spacing plug is carried out spacing spacing catch.
Because the utility model combines by three sections, after the construction, middle spiro rod section through walls still can for good and all be kept somewhere in body of wall as traditional approach, do not influence the wall body structure performance, but two sections standing screws at two ends can retract repeated use, both saved the input of steel, removed the various inputs of metope extension cutting again from, and can save construction to a great extent and drop into and building costs.In addition, the design of the taper type of spacing plug also is convenient to continue to retract out spacing plug after pulling down two sections standing screws, can further effectively reuse an assembly, thereby reduces construction cost.Usefulness of the present utility model also is, after construction finishes, as long as the standing screw at two ends is removed, be convenient to stripping like a cork, can not cause great hurt, can increase substantially the application life of template template, further reduce construction cost, reduce the wasting of resources.
Description of drawings
Fig. 1 is the structural representation of a kind of exemplary embodiment of the present utility model;
Fig. 2 is a user mode structural representation of the present utility model.
The specific embodiment
As Fig. 1, shown in Figure 2, Cast-in-place concrete template of the present utility model is made of the standing screw 1 at the screw rod through walls 5 of centre and two ends thereof and the spacing plug 2 that links together in order to standing screw 1 coaxial line with the screw rod through walls 5 of centre and two ends with the combined type through-wall bolt, the both ends of each screw rod all are processed with external screw thread, spacing plug 2 is the taper type structure, the centre of two table tops of taper type plug 2 is processed with the screw of axis direction, each screw rod links together by taper plug 2 spirals successively, the little table top of two taper plugs assembles inwardly, on the middle body of rod of centre screw rod 5 through walls, be fixed with seal plate 4, in the screw arranged around at least two dismounting grooves are arranged on the big table top outwardly of taper plug 2, on the body of rod at the two ends position of centre screw rod through walls, be fixed with the axial screw-in size of spacing plug is carried out spacing spacing catch.
During use, after each member is assembled into one successively, respectively inner and outer template 6 is through on two standing screws 1 of this through-wall bolt, the lumps of wood 7 and steel pipe 8 on outside template, filling up successively then, load onto clamp nut 9 then respectively at two ends and tighten, the big table top that template is pressed on two taper type plugs 2 gets final product.Construction is finished concrete and is solidified the back during form removal, can earlier clamp nut 9 be pulled down, and back-out standing screw 1, take off the lumps of wood and steel pipe, with the dismounting groove 10 on the big table top of instrument insertion taper type plug of buckle head, only rotate certain number of turns and get final product at last, the taper type plug is taken out, like this, two sections standing screws 1 and taper type plug 2 are all reusable.
It should be noted last that: above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the utility model, and not breaking away from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
