Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to specification text
Word can be implemented according to this.
It should be appreciated that it is used herein such as " have ", "comprising" and " including " term do not allot one or many
The presence or addition of individual other elements or its combination.
As depicted in figs. 1 and 2, the present invention provides a kind of new casting method for improving Surface Quality of Concrete, mainly includes
Following steps：
Step 1, by pouring face height banding steel cage 102, and formwork for placing is installed outside the steel reinforcement cage 102, institute
State the infiltration releasing agent of formwork for placing 100, the both sides face die plates butt joint edge 101 of the formwork for placing 100 turns down 90 ° laterally, described
The width of butt joint edge 101 is set to 30-50mm, and multiple grooves 104, the groove 104 are uniformly distributed along the longitudinal direction of the butt joint edge 101
Interior setting retaining mechanism.
Step 2, ground floor mortar 105 is poured to the formwork for placing 100 and back plate connections, the mortar 105 is poured
Thickness is 20-30mm.
Step 3, first steel wire of the parallel base plate setting in the top of the ground floor mortar 105 in the steel reinforcement cage 102
Mesh sheet, first steel fabric sheet is fixedly connected in the steel reinforcement cage 102, and the net of the steel fabric sheet 107 hole is set to triangle
Shape, the triangle inscribed circle diameter is set to 25-45mm.
Step 4, to the first layer concrete 106 is poured in the formwork for placing 100, pour thickness for 20-30mm.
Step 5, vibrating spear 108 is inserted into pours the bottom of the first layer concrete 106 for finishing and vibrated.
Step 6, treat the ground floor concrete initial set before, be arranged second in parallel in the top of first layer concrete 106
Layer steel fabric sheet, to the second layer concrete is poured in the formwork for placing 100, pours thickness for 20-30mm.
Step 7, the vibrating spear 108 is inserted to 15-20mm in the second layer concrete layer i.e. the first layer concrete
Vibrated at place.
Step 8, the operation of repeat step 6,7 pour until pouring completion.
In such scheme, by setting multiple grooves 104 on the formwork for placing butt joint edge, and in the groove
Retaining mechanism is set in 104, and the retaining mechanism fastens the formwork for placing 100, prevents template in concrete vibrating process
It is middle to produce displacement, and then avoid producing honeycomb inside and outside the concrete, while preventing concrete from the formwork for placing 100
Outflow, occurs running mould and the mould phenomenon that rises, and influences concrete appearance flatness；By horizontally disposed many in the steel reinforcement cage 102
The layer steel fabric sheet 107, the network of triangle hole of the steel fabric sheet 107 has good stability, described to connect in triangle
Connect circular diameter and be set to 25-45mm, in casting concrete, concrete need to be poured into through the steel fabric sheet 107, not influence to mix
In the case that solidifying soil is poured and the vibrating spear 108 vibrates, the steel fabric sheet 107 can prevent bulky grain concrete settlement from entering
LIFT, so as to ensure concrete integral structure and flat appearance degree；The set thickness that pours is conducive to concrete for 20-30mm
Interior bubble discharge, is also not in cross to shake and leakage is shaken phenomenon, and be inserted to for the vibrating spear 108 in placement layer by layer pour by concrete
Layer lower floor 15-20mm is vibrated, and interface concrete is fully blended, and the compactness between concrete is more preferable, concrete appearance
Quality is more preferably.
It is parallel described in the steel reinforcement cage 102 in the space between the formwork for placing 100 in one preferred scheme
The medial surface of formwork for placing 100 sets reinforcing bar plate 103, and the reinforcing bar plate 103 is fixedly connected on the steel reinforcement cage by reinforcing bar
102 sides, the reinforcing bar plate 103 is arranged at the medial surface 50-100mm of the formwork for placing 100.
In such scheme, the reinforcing bar plate 103, institute are set at the medial surface 50-100mm of the formwork for placing 100
State reinforcing bar plate 103 be disposed to prevent concrete outer surface produce crack, because hydration heat of cement produce temperature stress meeting
Cause crack, setting the reinforcing bar plate 103 increases concrete strength, prevent that concrete surface dehydration is too fast cannot to resist itself
Shrink, so as to produce crack.
In one preferred scheme, the formwork for placing 100 is phenolic paint composite plywood.
In such scheme, the phenolic paint composite plywood plate face is bright and clean, and assembly is convenient, and using effect is good, can be fine
The appearance requirement for meeting concrete construction.
In one preferred scheme, the distance between any two of the steel fabric sheet 107 is set to 50-100mm.
In such scheme, the setting of the distance does not interfere with concrete structure steadiness, and makes the concrete
Structure is firmer, is conducive to the connection that concrete is poured layer by layer.
In one preferred scheme, the distance between the groove 104 is 100-150mm.
In such scheme, the setting of distance ensure that the fastening journey of the connection of the formwork for placing 100 between the groove 104
Degree, farthest reduces the gap of the plate stitch of the formwork for placing 100, is conducive to concrete appearance integral smoothness.
Preferably, a diameter of 30-40mm of the caput of the vibrating spear 108.
In such scheme, the use of the caput of the vibrating spear 108 can ensure vibrating in reinforcing bar dense part concrete
Also it is fully closely knit so that concrete is closely connected, and overall structure and presentation quality are more preferably.
Preferably, the plate stitch clearance control of the formwork for placing 100 is in 0.5-1mm, the gap inner clip sponge.
In such scheme, concrete flows out the formwork for placing 100 when the control in the gap prevents concreting,
Sponge is pressed from both sides in gap, fine gap is preferably sealed using the pliability of sponge so that Surface Quality of Concrete is more preferably.
Preferably, the releasing agent main component is No. 200 industrial napthas, stearic acid and paraffin.
In such scheme, the releasing agent using effect is good, small to some in addition to having whitening effect to concrete surface
Bubble also has sealing role.
Although embodiment of the present invention is disclosed as above, it is not restricted to listed in specification and implementation method
With, it can be applied to various suitable the field of the invention completely, for those skilled in the art, can be easily
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited
In specific details and shown here as the legend with description.
