Abstract
The utility model relates to an I-shaped combined formwork abutting rod which is a tool for controlling thickness of a concrete wall column. The I-shaped combined formwork abutting rod comprises an abutting rod body and abutting caps, wherein the abutting rod body is provided with threads for the whole length, and the two abutting caps are provided with screw holes and fixed at two ends of the abutting rod body respectively through the screw holes. Each abutting cap is a T-shaped cylinder composed of a small cylinder body and a big cylinder body, and the screw holes are arranged on the small cylinder bodies. The I-shaped combined formwork abutting rod is installed on a concrete reinforcement mesh sheet in a vertical structure, can control a reinforcement protective layer and the size of a structural section, and protect the formworks on two sides better. The abutting caps at the two ends can be removed through rotation for recycling after concreting.
Description
Technical field
The utility model belongs to the realm of building construction, and particularly a kind of I shape combination backform rod, this combination backform rod are a kind of instruments of controlling concrete wall, column cross-section size, control topping during the building structure construction and protecting the both sides wooden form.
Background technology
In the building structure construction stage, body of wall, column section control and topping control are particularly important, and common method has two kinds; Be respectively reinforcing bar backform rod and concrete top template, but all there is defective in various degree in dual mode, a little less than reinforcing bar backform rod is controlled to topping; Protective value to the both sides wooden form is relatively poor, inserts easily in the wooden form, when the hidden danger that when exterior wall uses, is prone to produce from the backform rod seepage; The termination, both sides is prone to get rusty, and finishing is had a negative impact; And concrete backform rod tensile strength is low, in the concreting and the process of vibrating, is destroyed easily, and section is bigger, and the firm difficulty of colligation is big.Therefore a kind of new I shape combination backform rod that can control concrete wall, column cross-section size, control topping and protection both sides wooden form need be provided.
Summary of the invention
The purpose of the utility model is the technical scheme that proposes a kind of I shape combination backform rod, and push rod is provided with screw thread in the middle of this I shape combination backform rod, makes during with the reinforced mesh colligation to tie up at described I shape combination backform rod and thread can not slide.
To achieve these goals; The technical scheme of the utility model is: a kind of I shape combination backform rod; Comprise push rod and top cap, the elongated external screw thread that is provided with of described push rod, said top cap is provided with screw; Said top cap is two, and two top caps are separately fixed at the two ends of said push rod through screw.
Said top cap is formed " T " shape cylinder by small cylinder and large cylinder, and said screw is arranged on the small cylinder.
The upper surface of said top cap is provided with a circular groove, is provided with the hexagon convexity in the circular groove center.
Said combination backform rod length is less than concrete wall column thickness 2mm.
The beneficial effect of the utility model is: the utility model I shape combination backform rod is simple in structure, is easy to realize, installs and convenient disassembly.After the wall column reinforcing bar binding finishes; The utility model I shape combination backform rod is installed on the reinforced mesh according to certain spacing; I shape combination backform rod two ends are withstood template and can effectively be controlled the wall column sectional dimension; Because push rod is provided with screw thread and makes that tying up silk fixes push rod and reinforcing bar, push rod can not aboutly move, thereby thickness of protection tier is controlled; The top cap makes greater than push rod and protects form surfacing not to be destroyed in the formwork reinforcement process on the other hand; The top cap detachably reuses after the concreting; When exterior wall uses, can reduce from the hidden danger of backform rod infiltration, the top cap is removed the available mortar in back and is repaired, and reduces the influence of anti-rust to the finishing layer; And can confirm push rod length according to thickness of wall body, the top cap can be general.
Below in conjunction with accompanying drawing and embodiment the present invention is made a detailed description.

Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model top cap sectional drawing;
Fig. 3 is the utility model top crown portion view.
The specific embodiment
Embodiment one:
A kind of I shape combination backform rod, referring to Fig. 1, described backform rod comprise push rod 1 and top cap 2; The elongated screw thread 1-1 that is provided with of described push rod; Said top cap is provided with screw 2-1, and said top cap is two, and two top caps are separately fixed at the two ends of said push rod through screw.In the present embodiment, can control the total length that length that the top cap is screwed into push rod is come control combination backform rod as required.
The present embodiment preparation method is very simple; Said push rod and top cap are ferrous material and process, and wherein push rod can be purchased separately, but top cap casting; Said top cap is formed " T " shape cylinder by small cylinder 2-2 and large cylinder 2-3, and said screw is arranged on the small cylinder.
In the present embodiment, the diameter of push rod is 8mm, and the length of push rod is cut out according to the required size scene and cut; Size and the shape machine-shaping as requested of top cap, large cylinder outward flange diameter is 30mm, the small cylinder diameter is 12mm; Height 10mm is referring to Fig. 2 and Fig. 3.
The backform rod is installed in wall column reinforced mesh reinforcing bar right-angled intersection place upper end; A colligation is firm with tying up; Thickness of protection tier accurately is set during colligation, the wall column template is installed and carries out concreting, in time the top cap is backed out and cleaned out after the form removal; Cram with cement mortar at former crown cap position, the top cap can be reused.
Embodiment two:
Present embodiment is the improvement of on the basis of embodiment 1, carrying out; The part identical in the present embodiment with embodiment 1; Please understand with reference to disclosed content among the embodiment 1, embodiment 1 disclosed content should not be repeated in this description as the content of present embodiment here yet.
In the present embodiment; For the ease of dismounting, the upper surface of said top cap is provided with a circular groove 2-4, is provided with in the circular groove center because the protruding 2-5 of the hexagon of spanner; The protruding thickness of hexagon is 5-10mm, and such structure can the convenient construction personnel operation.
Embodiment three:
Present embodiment is the improvement of on the basis of embodiment 1, carrying out; The part identical in the present embodiment with embodiment 1; Please understand with reference to disclosed content among the embodiment 1, embodiment 1 disclosed content should not be repeated in this description as the content of present embodiment here yet.
In the present embodiment, in order better to control the thickness of concrete wall column, said combination backform rod length is less than concrete wall column thickness 2mm.
The above; Be merely the preferable specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or changes according to the technical scheme of the utility model and inventive concept thereof in the technical scope that the utility model discloses, and all should be encompassed within the protection domain of the utility model.
