Description

Quick adhering wall spacer

Technical field

The present invention relates to a kind of quick adhering wall spacer, it is formed in when constructing concrete steel building or structure in order to make interval between the reinforcing bar of being located at framework and arrangement of reinforcement keep certain and to tie up operation by the spacing body of being located at reinforcing bar being carried out 1 circle, will be vertical and horizontal reinforcement make reinforcing bar and framework maintenance certain intervals when tying up simultaneously.

Background technology

Usually, when constructing concrete steel building or structure, worker's method of employing be with the same interval of the concrete wall body thickness of wanting to construct with the setting of the mutual subtend shape of framework, fluid concrete between the framework of both sides then.

At this moment, for the both sides framework of mutual subtend shape is set with certain interval, two kinds of keepers are at interval arranged, a kind of is that framework and framework are directly supported, be processed into iron plate bar-shaped as material bending, the separator of under the horizontal state of being located between the framework of both sides, supporting, be located at the tie bolt that unrolls after PVC cone between the framework of both sides and pvc pipe use together, with the tapered cup nut that screws togather tie bolt be located at and the both sides framework between disengagement bolts, be used for the iron framework collapsible tie-down members of (claiming the stream model again), in addition, separated tie-down members etc. by supporting wooden or wooden one side with what the hole model of iron plate and stream structure of models constituted, multiple mode is arranged, and another kind is a reinforcing bar of being located at arrangement of reinforcement, be used to keep the interval of reinforcing bar and framework, the spacing body that forms by circular (annular).

Yet, as mentioned above, circular spacing body is by the plastics injection molding, break off by a side, the circle that is formed with the intercalation path of allowing the reinforcing bar intercalation supports that fixedly the center rim and the circular a plurality of linking ribs of edge and center rim of supporting of binding of reinforcing bar constitute for edge and intercalation, but the circular spacing body of this conventional art is for intercalation reinforcing bar easily, the internal diameter of center rim is formed the diameter that is a bit larger tham reinforcing bar, and will flexibly the arrangement of reinforcement that is intercalated in center rim be supported to 2 protrusion sheets that center line extends from the intercalation path, but, these 2 elastic force that protrude sheet support reinforcing bar are not firm, and because of having only the horizontal reinforcement intercalation, so when framework is set, can take place, and then when the casting cement mortar, the accident that circular spacing body is deviate from often takes place from reinforcing bar because of the phenomenon of pushing force from relaxation of steel.And,,, exist the problem that concrete strength weakens so can not combine with concrete because of circular spacing body is a plastic material.

The present invention is for solving above-mentioned variety of issue, even its purpose be to provide a kind of in order to construct wall body or pillar by the vertical reinforcing bar of arrangement of reinforcement and horizontal reinforcement being tied up 1 circle operation is tied up simultaneously and are had the pushing force also can be and also can not press, can keep firmly investing the spacing body of the state of reinforcing bar to the framework effect when framework is set because of the concrete mortar cast from relaxation of steel, the spacing body that another purpose is to provide the material that combined by the concrete mortar one with cast to make.

Content of the present invention

For achieving the above object, spacing body of the present invention is to invest the vertical reinforcing bar of arrangement of reinforcement or horizontal reinforcement to keep the interval of described reinforcing bar and framework when the wall body of constructing concrete steel building or structure and pillar, it is characterized in that, comprising: by concrete mortar with have the body that the material of binding affinity constitutes; Be formed at the mid portion of this body one side, under the state that caves in towards the opposite side seating surface of supporting framework, be cut into the reinforcing bar accepting groove of vertical configuration up and down with the width that can hold reinforcing bar; Be benchmark separately the end face mid portion of protuberance that is formed at its left and right sides, and be cut into two side slat grooves of vertical configuration up and down respectively with this reinforcing bar accepting groove; Be positioned at this two side slats groove rear side separately, the both sides through hole that the up/down perforation shape wears; And flexibly pressing a pair of Flexible clamp of inserting an elasticity pressure reinforcing bar under the state that is fixed in these both sides through hole separately.

Another feature is that described body is that concrete mortar is mixed postforming grade with the cement with binding affinity, kaolin, silica sand etc.

Another being characterised in that, described a pair of Flexible clamp is by integrally formed with lower member, comprising: flexibly crimping and be intercalated in the flexible arc portion of through hole inner face separately when being intercalated in the through hole of body both sides; Expose and be fixed in the anchor portion of through hole bottom separately; Both sides through hole and bar groove upper end are separately pressed the upper end support sector of propping up; Protrude and guide the guiding end of reinforcing bar intercalation from this two bulge; And flexibly press a reinforcing bar and body is anchored on the pressure branch of reinforcing bar.

In sum, adopt the present invention, when the wall body of constructing steel concrete and pillar, when the cross section of vertical reinforcing bar that body is arranged at arrangement of reinforcement and horizontal reinforcement quadrature shape, owing to vertical reinforcing bar can be contained in the reinforcing bar accepting groove of body, and, adhere to operation by a pair of Flexible clamp being carried out 1 circle, available strong elastic is arranged at horizontal reinforcement, therefore, the operation that body is set is easy, and has an effect of carrying out fast, again because body is set at the part that vertical reinforcing bar and horizontal reinforcement intersect, therefore compare with the structure that circular spacing body is arranged at horizontal reinforcement in the conventional art, it is big because of intensity is set, so have the effect that under the state of powerful ground and body driving fit, is provided with framework, and, when the fluid concrete mortar, can not deviate from or inclination such as release to the left and right, the state when but former state keeps being provided with, thus, have can be according to design wall body and pillar the time the fixed thickness effect of constructing, again, because the material of body has the binding affinity with concrete mortar, therefore, can combine with the concrete mortar one of cast, has the intensity that increases wall body and pillar, and, again because the circular spacing body material of conventional art is plastics, so when framework is disintegrated, the parts of plastics that is exposed to outside in wall body and the pillar must be beautified by concrete mortar and give hidden processing operation, but wall spacer of the present invention is because the material and the concrete mortar of body are same cement, when framework is disintegrated, because of the seating surface that exposes the body of outside in wall body and the pillar has and the same tone of concrete mortar, therefore, the processing operation of concentrating by compo in the past can be omitted, the humanware expense can be reduced so the present invention has, but and the advantage of reduction of erection time.
