Abstract

The utility model relates to an all-steel large template upper port positioning plate which belongs to the technical field of building construction tools and aims at overcoming the defects such as hard guarantee of thickness of a reinforcement protecting layer and position of the reinforcement, curved construction joint, and need of trimming after demoulding, which commonly appear in construction using all-steel large template reinforced concrete, especially in the construction process of shearing force wall upper port. The technical scheme is as follows: the positioning plate consists of angle iron and bolts, wherein a plurality of bolt holes are sequentially arranged on one lateral edge of the angle iron, the bolt holes are long holes, and the long edge of the long hole is along the vertical axis direction of the angle iron and parallel to the edge of the angle iron. After the positioning plate is fixed at a proper position of the template upper port, the position of the reinforcement on the upper port of the reinforced concrete structure using the all-steel large template can be effectively guaranteed not to deflect, the thickness of the protecting layer is accurate, and a plurality of layers of cushion blocks for the reinforcement protecting layer can be saved; furthermore, the construction joint can be guaranteed to be horizontally smooth and straight, and after concrete casting, post processing procedures such as leveling, line snapping, cutting, picking and chiseling and the like are conducted, thus being labor-saving and time-saving, and reducing construction cost.

Description

All steel large form location-plate suitable for reading

Technical field

The utility model relates to a kind of orientation tool that uses when all steel large form steel concrete is poured into a mould, belong to the building operations technical field of tools.

Background technology

Use all steel large form reinforced concrete construction at present; especially shear wall; cushion block is mainly adopted in the control of topping and reinforcement location; cushion block adopts the galvanized wire colligation more or directly is clipped on the main muscle; there is unsteady problem; under the concreting and the load action that vibrates, often cause the displacement of cushion block or come off.And in the building structure section construction process, every segment structure reserved steel bar suitable for reading influences workmanship often because of construction causes deflection.Simultaneously, the reinforced concrete wall panel construction joint is handled concrete construction quality, organoleptic quality influence bigger, mostly is to carry out levelling, snap the line after reinforced concrete wall is built, cut, pick post-processed such as cutter, becomes horizontal construction joint at last, takes a lot of work, time-consuming.

Summary of the invention

Technical problem to be solved in the utility model is to overcome present use all steel large form reinforced concrete construction; especially thickness of protection tier that often occurs in the shear wall work progress suitable for reading and reinforcement location are difficult to guarantee, constuction joint is not straight, need the defective of finishing after the form removal; provide a kind of can instead of steel tendon protective layer cushion block, and guarantee the straight all steel large form location-plate suitable for reading of constuction joint level.

The technical scheme that solves the problems of the technologies described above is:

A kind of all steel large form location-plate suitable for reading, it is made up of angle steel and bolt, and order is arranged a plurality of bolts hole on a side of angle steel, and bolt hole is a slotted hole, the long edge angle steel y direction of slotted hole, and parallel with the edge of angle steel.

The beneficial effects of the utility model are: after location-plate is fixed on template suitable location suitable for reading, can effectively guarantee to use the reinforcement location suitable for reading deflection not of the reinforced concrete structure of all steel large form, protective layer thickness is accurate, and can save several layers of reinforcement cover cushion block; Can guarantee that again the constuction joint level is straight, reduce concreting after, levelling, snap the line, cut, pick post-processed operation such as cutter, the saving of labor, save time, reduce construction cost.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the scheme of installation of the utility model and template;

Fig. 3 is a use schematic diagram of the present utility model.

Mark is as follows among the figure: angle steel 1, concreting absolute altitude 2, topping 3, cushion block 4, reinforcing bar 5, bolt 6, all steel large form 7, slotted hole 8

The specific embodiment

Shown in Figure 1, location-plate is made up of angle steel 1 and bolt 6, and order is arranged a plurality of bolts hole on a side of angle steel 1, and bolt hole is a slotted hole 8.

Shown in Figure 2, angle steel 1 is connected and fixed with all steel large form 7 usefulness bolts 6.

Shown in Figure 3; use the reinforced concrete structure of all steel large form; after 7 installations of all steel large form are reinforced and are finished; at template installation angle steel 1 suitable for reading, angle steel 1 is seen Fig. 2 with being connected of template, after angle steel 1 fixes; make the edge of the horizontal sides of angle steel 1 be close to the vertical reinforcement 5 of structure; with the deflection of restriction building iron 5, and the distance of angle steel 1 edge to template inboard equals the thickness of the reinforcement cover 3 of reinforced concrete structure, can save reinforced concrete structure number layer reinforcement cover cushion block 4.The height of the horizontal sides lower edge of angle steel 1 is than the high 5-10mm of end absolute altitude of the concrete beam that will pour into a mould or concrete slab, the constuction joint level is straight after can guaranteeing concreting, after exempting form removal, constuction joint levelling, snap the line, cut, pick post-processed operations such as cutter, angle steel 1 is pulled down behind concrete initial set and is cleaned out, in order to using next time.

Claims

1. all steel large form location-plate suitable for reading, it is characterized in that: it is made up of angle steel [1] and bolt [6], and order is arranged a plurality of bolts hole on a side of angle steel [1], and bolt hole is slotted hole [8], long edge angle steel [1] y direction of slotted hole [8], and parallel with the edge of angle steel [1].
