Problems solved by technology

[0002] The concrete interception of cast-in-place concrete beams at the post-pouring belt or construction joints is usually carried out by vertically inserting wooden squares or steel bar heads and steel wire mesh into the beams. Due to the large number of densely ribbed beams, the cross-section of the beam is different from the conventional "mouth", if the wooden square or steel bar head is used to insert vertically, it is not easy to operate; moreover, the large number of densely ribbed beams requires The number of wooden squares and steel bar heads is relatively large, which is uneconomical and the blocking effect is not good. Therefore, the industry is in urgent need of a blocking device and method that has a good blocking effect on concrete, is convenient to operate, and is economical.

Embodiment 1

[0043] Such as Figure 1-10 As shown, a concrete blocking device for the post-pouring belt of densely ribbed beams, including a main fence 1, an auxiliary fence 2 and a partition fence 3, is characterized in that: the main fence 1 and the auxiliary fence 2 They are all wrapped with scotch tape 4 . After wrapping with scotch tape 4 , the compressive strength of the main fence 1 and the auxiliary fence 2 can be increased, and the vibration and impact during the pouring of the concrete 12 can be resisted. The separation block 3 is composed of the second dense rib beam stirrup 3b and the dense mesh steel wire mesh 3c, that is, the second dense rib beam stirrup 3b is wrapped with the dense mesh steel wire mesh 3c; The position of the first dense rib beam stirrup 3a is first inserted into the auxiliary fence 2 and close to the first dense rib beam stirrup 3a, and then inserted into the main fence 1, and the front of the main fence 1 (the cut surface of the transparent tape) is close t...

Embodiment 2

[0048] A method for blocking concrete at the post-casting zone of densely ribbed beams, the specific steps are as follows:

[0049] (1) Construction of ribbed floor structure:

[0050] First set up the template support frame body 10, lay and fix the shaping formwork 8 on the formwork support frame body 10, then fill the extruded plastic plate 9 between the bottoms of the shaped formwork 8, paste the transparent tape 4 on the extruded plastic plate 9, and then Bind the upper steel bar 5 of the densely ribbed beam, the first densely ribbed beam stirrup 3a and the lower steel bar 6 of the densely ribbed beam, and finally carry out the construction of the plate steel bar 7;

[0051] (2) Production of foldable main fence 1:

[0052] The main fence 1 is special-shaped, the height is the net size between the upper reinforcement 5 of the dense rib beam and the lower reinforcement 6 of the dense rib beam after the reinforcement of the dense rib beam is bound, and the width is the sect...

Abstract

The invention discloses a device and method to intercept concrete at a dense-rib beam post-cast strip. The device comprises a main blocking plate, an auxiliary blocking plate and a separator blockingnet; both the main blocking plate and the auxiliary blocking plate are wrapped in transaprent adhesive tape; the separator blocking mesh is formed by tying second dense-rib beam stirrups and a dense-mesh wire mesh. The method comprises: selecting the position for the first dense-rib beam stirrups on the post-cast strip, inserting the auxiliary blocking plate close to the first dense-rib beam stirrups, inserting the main blocking plate with the front thereof attached to the auxiliary blocking plate, and inserting the separator blocking net close to the main blocking plate. The device and methodhave the advantages that materials are taken in situ, extruded plates are used as a material that is lower in cost than traditional rebar ends and timber, the advantages, certain compressive strengthand elasticity, of the extruded plates are utilized, cutting is facilitated, good sealing is provided for stuffing, and the blocking effect is good.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a device and method for blocking concrete at the post-pouring belt of densely ribbed beams, and is suitable for blocking concrete at the post-casting belts, expansion reinforcement belts and construction joints of densely ribbed beams. technical background [0002] The concrete interception of cast-in-place concrete beams at the post-pouring belt or construction joints is usually carried out by vertically inserting wooden squares or steel bar heads and steel wire mesh into the beams. Due to the large number of densely ribbed beams, the cross-section of the beam is different from the conventional "mouth", if the wooden square or steel bar head is used to insert vertically, it is not easy to operate; moreover, the large number of densely ribbed beams requires The number of wooden squares and steel bar heads is relatively large, which is uneconomical and the blocking effect i...
