Abstract
The utility model discloses a clamp for supporting a lower reinforcing steel bar of a floor slab and resisting floatation of the lower reinforcing steel bar of the floor slab. The clamp comprises a floating-resisting plate and a supporting plate which are sequentially connected from top to bottom, wherein the cross section of the floating-resisting plate is in an omega shape, the cross section of a supporting part of the supporting plate is in a concave shape, the concave supporting part of the supporting plate is embedded into a convex groove of the floating-resisting plate, the size of the groove of the supporting plate is matched with that of the lower reinforcing steel bar of the floor slab, the vertical distance from the bottom surface of the groove of the supporting plate to a mold plate is equal to the thickness of a protection layer of the reinforcing steel bar, and the floating-resisting plate and the supporting plate are fixed on the mold plate together. By adopting the clamp, the thickness of the protection layer is effectively guaranteed, the precision of the protection layer is improved, and the construction efficiency of the floor slab can be improved. The clamp is convenient to construct, high in precision, reasonable in structure, convenient to machine, convenient in material fetching, low in cost and capable of realizing factorized production.
Description
Technical field
The utility model relates to a kind of jig for floor lower floor reinforced bar support and anti-floating, is specially adapted to the control of construction work cast-in-place concrete floor lower floor reinforcement cover.
Background technology
In existing the Concrete Structure Design, durability, safety and the use function of the thickness of reinforcement cover to structure played vital effect.But, in structural solid in recent years detects, find, cast-in-place concrete floor thickness of protection tier be controlled to the weak link for quality control.The cushion block adopting in traditional construction technology often because size is too little, intensity is low, reinforce not firm, leak and put, vibrator vibrates and personnel trample etc. factors and cause concrete cover can not meet code requirement in addition; And the mostly floor not anti-floating measure of lower floor's reinforcing bar or be only fixed with iron wire, can not meet its required precision temporarily, become and in concrete the work items, be badly in need of the common quality defect that solves.
Utility model content
The utility model provides a kind of jig for floor lower floor reinforced bar support and anti-floating for solving the technical problem existing in known technology, and this jig can make the concrete cover of floor reach the requirement of standard.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is: a kind of jig for floor lower floor reinforced bar support and anti-floating, comprise the anti-floating plate and the gripper shoe that connect successively from top to bottom, the cross sectional shape of described anti-floating plate is " Ω " shape, the cross sectional shape of the support section of described gripper shoe is " recessed " font, " recessed " font support section of described gripper shoe is embedded in the tongue of described anti-floating plate, the size adaptation of the groove size of described gripper shoe and floor lower floor reinforcing bar, the groove floor of described gripper shoe to the vertical distance of template equals floor bar protective layer thickness, described anti-floating plate is fixed in template together with described gripper shoe.
In described anti-floating plate and described gripper shoe, be equipped with zinc coat.
Described anti-floating plate and described gripper shoe are followed closely in described template by iron nail.
Advantage and the good effect that the utlity model has are: by floor lower floor reinforcing bar is locked between the groove of gripper shoe and the tongue of anti-floating plate, and be fixed on the structure in template, jig is stably fixed between floor lower floor reinforcing bar and template; Further, make groove floor to the vertical distance of template of gripper shoe equal floor bar protective layer thickness, thereby can effectively guarantee the thickness of floor bar topping, improve the precision of floor bar topping, improve the efficiency of construction of floor.And the utility model easy construction, accuracy be high, rational in infrastructure, easy to process, be convenient to draw materials, with low cost, can batch production make.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use schematic diagram of the present utility model.
In figure: 1, anti-floating plate; 2, gripper shoe; 3, circular hole; 4, iron nail; 5, floor lower floor reinforcing bar; 6, template.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, a kind of jig for floor lower floor reinforced bar support and anti-floating, comprise the anti-floating plate 1 and the gripper shoe 2 that connect successively from top to bottom, the cross sectional shape of described anti-floating plate is " Ω " shape, the cross sectional shape of the support section of described gripper shoe 2 is " recessed " font, " recessed " font support section of described gripper shoe 2 is embedded in the tongue of described anti-floating plate 1, the size adaptation of the groove size of described gripper shoe 2 and floor lower floor reinforcing bar 5, the groove floor of described gripper shoe to the vertical distance of template 6 equals floor bar protective layer thickness, described anti-floating plate 1 is fixed in template 6 together with described gripper shoe 2.
In the present embodiment, in described anti-floating plate 1 and described gripper shoe 2, be equipped with zinc coat.To extend their application life.The both sides of described anti-floating plate 1 and described gripper shoe 2 all offer the circular hole 3 passing through for iron nail 4, and described anti-floating plate 1 and described gripper shoe 2 are followed closely in described template 6 by iron nail 4.
The sagitta of above-mentioned anti-floating plate 1 equals floor bar protective layer thickness and floor lower floor bar diameter sum, and the bilateral symmetry of described anti-floating plate arranges circular hole 3, and the diameter of circular hole 3 should be than the slightly larger in diameter of iron nail 4.
The vertical distance of the notched bottoms of the support section of above-mentioned gripper shoe 2 and template 6 should equal floor bar protective layer thickness.The both sides of gripper shoe 2 are provided with and circular hole 3 identical on anti-floating plate 1, and the structure of gripper shoe 2 coupling parts is identical with the structure of anti-floating plate 1 coupling part.
After reinforcing bar 5 colligations of floor lower floor complete, lock it between the groove of described gripper shoe 2 and the tongue of described anti-floating plate 1, and be fixed in template 6.
Although by reference to the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, can also make a lot of forms, within these all belong to protection domain of the present utility model.
