Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
In the prior art, a settlement joint construction method comprises the following steps:
(1) firstly, pouring a component to paste the foam board:
and constructing the column and beam members on one side and then constructing the column and beam members on the other side. And (3) erecting a template at the construction part according to a conventional method, after pouring concrete and removing the template, sticking foam plates with the same thickness and width as the settlement joints on the settlement joint sides of the columns and the beams to be used as side templates for constructing the settlement joints of the columns and the beams, binding reinforcing steel bars and erecting an internal mold.
The method comprises the following steps:
a. the formwork expanding phenomenon is easy to occur due to the fact that the formwork supporting component cannot be provided with the split bolts and the inner side formwork is relatively difficult to reinforce;
b. because the foam board replaces the template to use, when the concrete vibrates, smash the foam board to pieces easily, garrulous foam board gets into in post, the roof beam easily and the concrete easily flows into the subsiding crack, brings the quality hidden danger for the engineering. It is difficult to ensure the quality of the appearance.
c. The bottom die is a wood template, one side close to the settlement joint is a foam board, the splicing of the template at the joint of two different materials is difficult, slurry leakage at the splicing joint is easy to occur, and the quality is affected.
d. The foam board sticking has the disadvantages of great labor input, high material cost and corresponding increase of construction cost.
(2) Flitch side top
And constructing the column and beam members on one side and then constructing the column and beam members on the other side. And (3) erecting a template at the constructed part according to a conventional method, and after pouring concrete and dismantling the template. And (3) processing battens with slightly longer lengths according to the width of the settlement joint (minus the thickness of the formwork) on the side formwork of the settlement joint of the column and the beam which are constructed after being laid down, and smashing the settlement joint into a wooden hammer to serve as the side top of the side formwork.
The method comprises the following steps:
a. the batten side-top mode causes the stress of the template to be too concentrated and uneven, and the template at the interval part of the batten and the batten is easy to expand and deform.
b. The problem of lateral stress in the die is only solved by the side top of the batten, and the joint of the bottom die and the side die is easy to explode.
(3) Steel-wood combined template
When the column and beam components on one side are constructed firstly, the steel templates of the column and the beam on the other side are fixed by screws after the back ridges and the steel pipes on one side. After the member poured firstly is finished, the template is not dismantled. The fixed steel template is used as a side mold for casting a side column and a beam.
The method comprises the following steps:
a. and the pouring of the components on the two sides is completed, and the middle template of the settlement joint is difficult to remove.
b. The steel form needs special processing customization because each architectural design settlement joint width is different, and the steel form needs special customization, and the commonality is not strong.
c. The steel form is difficult to dismantle, and the damage rate is high in the forced dismantling process. The turnover frequency of the same project is low. In addition, the cost for customizing the steel template is high, and the economic benefit is lower.
To distinguish from the prior art solutions, as shown in fig. 1-3, which show construction diagrams in an embodiment of the present invention, the embodiment of the present invention relates to a method for framing structure settlement joint formwork erection, the method comprising, on one side of the framing structure:
s1: lofting for the first time, wherein the lofting is carried out on the beam column of the frame structure;
s2: modeling, namely erecting a template 4 in the lofting area;
s3: firstly, casting a component, and casting concrete in a modeling area;
s4: and removing the side template 4 after the casting component is finished.
Further elaboration of this solution is that on the other side of the frame structure:
s5: secondary lofting, namely lofting the other side of the beam column of the frame structure;
s6: a rear pouring member, which is used for pouring concrete in the modeling area;
s7: and (5) secondary form removal, and removing the side form 4 after the cast component is completed.
It is mainly noted that in the above steps of the method, only one modeling operation is needed to be performed on two ends of a beam column of the framework structure after lofting, and repeated modeling is not needed, in the process of one modeling, templates 4 need to be supported at two ends of the framework structure at the same time, the supports of the templates 4 at the two ends are kept symmetrical and parallel as much as possible, and template fixing members are arranged at the edges of the templates 4.
Wherein, above-mentioned template mounting includes: a butterfly nut 5 that is used for consolidating steel pipe 2 and a plurality of flitch 3 of template 4, and be used for locking template 4 to the stay bolt 1, a plurality of flitches 3 are according to the vertical setting of minor face between steel pipe 2 and template 4, thereby it produces certain construction gap to be used for raising up template 4, thereby stay bolt 1 is used for drawknot two templates 4, it needs to notice be, in this embodiment, a butterfly nut that is used for locking stay bolt 1 is pre-buried in pouring the region earlier, and need not take out, then pour the region and be used for locking the butterfly nut of stay bolt 1 and lock through the mode of hammering, can shelter from the cover with the nut of pouring the region afterwards for pleasing to the eye.
In the embodiment of the invention, the widths of the template 4, the steel pipe 2, the batten 3 and the split bolt butterfly nut 5 need to be recorded as H, D, H and D in sequence, and the H + D + H + D is regulated to be less than or equal to 200mm, and it can be understood that the design specification requirement of the settlement joint of the high-rise dwelling house is 200mm-300mm at present, so when the template is arranged in the settlement joint of the frame structure, the sum of the thicknesses of the template and other fixing devices does not exceed the width requirement, otherwise, pouring cannot be carried out.
At the end of this scheme, at S7: after the step of secondary form removal, the method also comprises the following steps:
s8: filling gaps, removing the split bolts 1, polishing the settlement joints, filling mortar, and trowelling, wherein the split bolts 1 are taken out after the settlement joint structure is completed, the split bolts 1 can be mechanically cut off or the handheld electric grinder is used for polishing, antirust paint is smeared inside the settlement joints, and trowelling is carried out through waterproof mortar.
The embodiments of the present invention have been described in detail, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
