Abstract
The utility model discloses a silo concrete protecting layer locating piece in slipform construction, for solving the technical problem of providing the silo concrete protecting layer locating piece in slipform construction, which has high strength, prevents water permeability, is not easy to release and is simply and conveniently manufactured, the utility model adopts the technical solution thatthe silo concrete protecting layer locating piece in slipform construction is characterized in that a reinforced bar rack and a steel formwork are arranged in a silo, a locater is arranged between thereinforced bar rack and the steel formwork, the locator is a n-shaped reinforced bar structure, one side of the locater is fixed on the reinforced bar rack, and the other side props up the steel formwork. The locating piece has the advantages of simple structure, firm fixation and convenient use, can reduce the working time, saves labor and material resources, improves the construction efficiency, greatly reduces the construction cost, has higher application value, and is beneficial to popularize and apply.
Description
Technical field
The utility model relates to a kind of when the round silo slding form operation, the slding form operation silo concrete cover keeper of bulkhead vertical reinforcement.
Background technology
" concrete structure engineering construction quality standards of acceptance " (GB50204-2002) pointed out: the concrete cover to reinforcement thickness relationship is to performances such as the bearing capacity of structure, durability, fire prevention; too thin easy infiltration wet gas of topping and water in the concrete; the blocked up crack that then easily produces; these all may make corrosion of steel bar and expand; thereby concrete is wrecked; influence is used and structural safety, and the control of thickness of protection tier is a ring very important in the reinforced concrete works quality.
The reinforced concrete protective layer keeper that is used for construction work; mainly be various cushion blocks, generally be equipped with bayonet socket groove in the arc-shaped, closely be stuck on the reinforcing bar or be supported on the bottom of reinforcing bar; differentiation has cement mortar cushion block, plastic cushion and concrete pad according to material.Available coagulation soil topping keeper has the following disadvantages:
1, the mortar cushion block phenomenon of cushion block became uneven usually occurs owing to be to make by hand, and the place is narrow, it is pressed for time, proportioning is random etc., and problem also often causes the intensity of mortar cushion block barely satisfactory, once stressed breakage.Also have, the colligation of mortar cushion block is not firm, often causes most cushion block to get loose when sealing template and vibrating.
2, low, the anti-water permeability of the intensity of plastic cushion is poor; The concrete mats bulk strength meets the demands, but the manufacturing cost height.
3, above-mentioned cushion block only is suitable for end muscle, the top reinforced concrete topping of common buildings engineering, and for the round silo structure of slding form operation, longitudinal reinforced concrete topping cushion block is easily loosening, the installation cost height, and practicality is not strong.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of intensity height, anti-permeable, be difficult for getting loose and slding form operation silo concrete cover keeper simple for production.
For solving the problems of the technologies described above; the utility model is by the following technical solutions: a kind of slding form operation silo concrete cover keeper; built-in reinforced frame of silo and steel form; be provided with keeper between described reinforced frame and the steel form; described keeper is a n shaped steel muscle structure; one side of described keeper is fixed on the reinforced frame, and opposite side withstands steel form.
The width of keeper described in the utility model equals slding form operation silo thickness of concrete cover.
The width of keeper described in the utility model is 15mm～30mm, and bar diameter is
16mm～
32mm.
The utility model compared with prior art has simple in structure, fixation, advantage easy to use; Can the reduction of erection time, use manpower and material resources sparingly, improve efficiency of construction, reduce construction cost greatly; Have higher using value, help applying.
Description of drawings
Fig. 1 is the vertical view after the utility model is installed.
Fig. 2 is the longitudinal profile schematic diagram after the utility model is installed.
Fig. 3 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2 and shown in Figure 3; the utility model slding form operation silo concrete cover keeper; built-in reinforced frame of silo and steel form 1; be provided with keeper 2 between reinforced frame and the steel form 1, described keeper 2 is a n shaped steel muscle structure, wherein; one side of keeper 2 is fixed on the reinforced frame; opposite side withstands steel form 1, and the width W of keeper 2 equals slding form operation silo thickness of concrete cover, and reinforced frame is made up of circumferential reinforcement 3, vertical reinforcement 5 and 4 colligations of skeleton horizontal bar.
The utility model keeper becomes n type structure by reinforcement fabrication, can be at bar diameter according to environment category and strength grade of concrete
16mm～
32mm selects between keeper width 15mm～30mm.Keeper is symmetry installation successively above the part D that constructs, and a face down bonding is connected on the bulkhead circumferential reinforcement, and opposite side then withstands steel form, and the width W of keeper is slding form operation silo thickness of concrete cover.Concrete mode is to be raised to predetermined altitude when sliding shuttering system cunning; after the bulkhead reinforcing bar binding is good; choose the n type keeper of the corresponding width of regulation thickness of concrete cover; be welded on the circumferential reinforcement; the about at interval 2m of silo hoop welds a place, accurately is controlled at specific thickness and is as the criterion to enable spacing with steel form and reinforced frame.Through evidence, the utility model keeper can effectively keep bulkhead vertical reinforcement and template spacing when silo concreting, accurately control thickness of concrete cover, after the concrete final set as the part of the built-in reinforced frame of silo and exist.
The utility model is simple in structure, intensity is high, dimensional uniformity is good, and has anti-permeable, anti-The advantage that gets loose, easily installs, greatly reduction of erection time, effective reducing construction cost, raising construction effect Rate, the application value height.
