Description

A kind of armored concrete slab concrete goods reinforcement flute profile split heads

(1), technical field

The utility model relates to when the reinforced concrete structure plate is constructed in construction work, especially for the locator (split heads) that supports and prevent mobile top reinforcement, spacing about keeping between double-layer double-direction reinforcing bar and the reinforcing bar, the prestressing force of raising reinforced concrete structure plate.

(2), background technology

When split heads is used for the construction of reinforced concrete structure plate, for the reinforcing bar of double-layer double-direction up and down that guarantees the reinforced concrete structure plate and the even branch between the reinforcing bar, to improve the prestressing force of floor and roofing, the existing practice: be with cuboid or Cylinder shape cement mortar cushion block goods, pad is up and down between double-layer double-direction reinforcing bar two reinforcing bars, keep corresponding spacing, pour into concrete setting then and be shaped.This mode with double-layer double-direction reinforcing bar about cushion block support and anti-the moving exists following deficiency: the cushion block volume is bigger, heavy, installation is wasted time and energy, because cushion block and reinforcing bar contact position are smooth, usually easily under concrete motive force and vibration effect, relatively move between cushion block and the reinforcing bar, even cushion block comes off, and it is not excessive making the spacing between reinforcing bar and the reinforcing bar, is exactly too small, can not be satisfied with construction requirement, have a strong impact on workmanship.The existing plastics split heads that also has a kind of plastics to make, its top is provided with the anti-notch that moves of cross, though it has overcome above-mentioned deficiency, but it exists maximum problem to be: because it is made of plastic, its coefficient of expansion is concrete 3-4 times, therefore, it is the cost height not only, do not prevent fires, easy to leak, intensity is low, and it is buried in the cast-in-situ floor and roofing of load-bearing structural member, because of the coefficient of expansion than big-difference, reinforcing bar in plastics split heads and the concrete breaks away from each other, produce the crack, malaria enters, the corrosion reinforcing bar, will damage the structure in floor and house for many years, cause serious hidden danger.

(3), summary of the invention

The purpose of this utility model just provides a kind of a kind of armored concrete slab simple in structure, that intensity is high, easy to use and with low cost concrete goods reinforcement flute profile split heads, it not only can improve the quality of building engineering structure, improved efficiency of construction, reduce engineering cost, and, avoided not preventing fires of plastics split heads inconsistent with its coefficient of expansion of plastics split heads, produce the crack, malaria enters, and the corrosion reinforcing bar causes serious hidden danger.

The purpose of this utility model is to realize by such technical scheme; it includes concrete stool body upper end; be provided with the perforation cross recess or a groove of the anti-different level that moves of support limit top reinforcement; a different level cross recess absolute altitude or a groove absolute altitude; be limited in the top reinforcement thickness of concrete cover, a cross recess or a groove that concrete stool body lower end is arranged to connect.Be provided with the metal ribs of U-shaped or I shape in the concrete stool body; it is characterized in that: be arranged to a cross recess or the groove that same horizontal plane connects with the concrete stool body lower end that concrete is made; a cross recess or a groove with the upper end different level; the support limit top reinforcement; making up and down, the double-layer double-direction reinforcing bar forms mutual constraint; concrete stool body is not shifted by what vibration or promotion no matter when pouring into concrete; all can make adjacent two reinforcing bars up and down can keep the spacing that should have all the time; the perforation cross recess absolute altitude or a groove absolute altitude of concrete stool body upper end different level; absolute altitude as the top reinforcement thickness of concrete cover; be provided with the metal ribs of U-shaped or I shape in the concrete stool body; increased the intensity of concrete stool body; lost by external force; concrete stool pin also has muscle to link to each other; do not influence its use; the pressure that still can bear in the construction to be produced; avoided the fragility of concrete stool body; concrete pours into and recovers its intensity; and operation is very easy; improve the quality of construction work and improved efficiency of construction, reduced engineering cost.

Owing to adopted technique scheme, the utlity model has simple in structure, intensity is high, easy to use, with low cost and make advantages such as easy, because the stool body is that concrete is made, its coefficient of expansion is consistent substantially with concrete, thereby reduces significantly because of expansion coefficient difference and the hidden danger that causes of fireproof material not.

(5), the specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As Fig. 1; 2; 3; shown in 4 or 5; the utility model includes different level and connects a upper end cross recess or a groove 1; a different level cross recess absolute altitude or a groove absolute altitude 5; in establish U-shaped or I shape metal ribs 4; there is the concrete stool body 2 that connects a cross recess or a groove 3 lower end; it is characterized in that: concrete stool body 2 bottoms are provided with and connect a cross recess or a groove 3; concrete stool body 2 upper surfaces are provided with the different level cross recess or a groove 1 of support limit top reinforcement; concrete stool body (2) upper end is provided with the different level cross recess absolute altitude or a groove absolute altitude (5) of spacing top reinforcement concrete cover; in order to overcome the fragility of concrete stool body; be provided with the metal ribs 4 of U-shaped or I shape in the concrete stool body; be configured in concrete stool body and the stool pin; concrete stool pin is lost by external force in transportation; also have muscle to link to each other; the pressure that still can bear in the construction to be produced does not influence its use.

Because concrete stool body of the present utility model 2 lower ends are provided with the perforation cross recess or a groove 3 of same level face, a different level cross recess or a groove 1 with upper end support limit top reinforcement, making up and down, the double-layer double-direction reinforcing bar forms mutual constraint, what vibration no matter restriction concrete stool body be subjected to or promote not to be shifted, all can make adjacent two reinforcing bars up and down can remain the spacing that should have, and operation is very easy, thereby workmanship and efficiency of construction have been improved.Because the stool body is that concrete is made, its coefficient of expansion is consistent substantially with concrete, thereby reduces expansion coefficient difference significantly and the hidden danger of the material of not preventing fires.

As shown in Figure 5, for the intensity that strengthens concrete stool body 2 and overcome concrete stool body and the fragility of stool pin, concrete stool body and stool pin inside are provided with the metal ribs 4 of U-shaped or I shape, are configured in concrete stool body and the stool pin.

As shown in Figure 5, concrete stool body 2 upper surfaces are provided with a different level cross recess absolute altitude or a groove absolute altitude 5, act on the thickness of spacing top reinforcement concrete cover.

As shown in Figure 1, concrete stool body 2 outer shape can be the circular cone cylindricality.As shown in Figure 2, concrete stool body 2 outer shape can be cylindrical.As shown in Figure 3, concrete stool body 2 outer shape also can the side's of being platform shape.As shown in Figure 4, concrete stool body 2 outer shape can also be cube shaped.
