Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
In the prior art, the construction method of the settlement joint comprises the following steps:
① Firstly, pouring a component to paste a foam board:
The column and the beam member on one side are firstly constructed, and then the column and the beam member on the other side are constructed. And (3) erecting the formwork according to a conventional method at the constructed position, after the concrete is poured and the formwork is removed, pasting foam plates with the thickness the same as the width of the settlement joint on the settlement joint sides of the column and the beam, taking the foam plates as side formworks of the settlement joint of the post and the beam, binding reinforcing steel bars and erecting an inner formwork.
The defects are as follows:
a. The formwork supporting component is difficult to reinforce due to the fact that the split bolts cannot be arranged after the construction method, and the formwork expansion phenomenon is easy to occur;
b. Because the foam board is used as a template, when concrete vibrates, the foam board is easy to smash, the smashed foam board easily enters the columns and the beams, and concrete easily flows into the settlement joint, so that the quality hidden trouble is brought to the engineering. It is difficult to secure the appearance quality.
C. The bottom die is a wood die plate, one side close to the settlement joint is a foam plate, the joint of the die plates of two different materials is difficult, and slurry leakage at the joint is easy to occur, so that the quality is influenced.
D. the pasting foam board has large labor and material cost, and the construction cost can be correspondingly increased.
② Side roof of wood square
Firstly, constructing a column and a beam component on one side, and then constructing a column and a beam component on the other side. And (3) erecting the template according to a conventional method at the site where the construction is performed, and removing the template after the concrete is poured. And (3) processing a side template of the post and beam settlement joint constructed after putting down, namely, a wood square with a slightly longer length according to the width of the settlement joint (the thickness of the subtracted template), and using a wood hammer to smash into the settlement joint to serve as a side top of the side template.
The defects are as follows:
a. The side-propping mode of the battens causes too concentrated stress and uneven stress of the templates, and the templates at the intervals between the battens are easy to expand and deform.
B. the side roof of the wood only solves the problem of side stress in the die, and the junction of the bottom die and the side die is easy to burst.
③ Steel-wood combined template
When the column and beam components on one side are constructed, the steel template of the column and beam on the other side is fixed by a screw after the back edge and the steel pipe on one side are constructed. And after the pouring of the component is finished, the template is not dismantled. And the fixed steel template is used as a side mould for pouring a side column and a beam.
The defects are as follows:
a. and the pouring of the two side components is completed, and the middle template of the settlement joint is difficult to remove.
B. The steel forms are required to be specially processed and customized, and because the settlement joint widths of all building designs are different, the steel forms are required to be specially customized, and the universality is not strong.
C. The steel form is difficult to disassemble, and the damage rate is high in the forced disassembling process. The turnover number of the same project is low. In addition, the cost of customizing the steel template is high, and the economic benefit is low.
In order to distinguish from the prior art, as shown in fig. 1-3, there is shown a construction diagram in an embodiment of the present invention, which relates to a method for setting up a settlement joint formwork of a frame structure, the method comprising, on one side of the frame structure:
s1: setting out the sample at one time, and setting out the beam column of the frame structure;
s2: modeling, namely supporting a template 4 in a region where lofting is completed;
S3: firstly pouring a member, and pouring concrete into the modeled area;
s4: and (5) removing the mold once, and removing the side mold plate 4 after the pouring of the component is completed.
Further perfecting this scheme, namely, on the other side of the frame structure:
S5: secondarily lofting, namely lofting the other side of the beam column of the frame structure;
S6: pouring a member, namely pouring concrete into the modeled area;
S7: and (5) removing the die secondarily, and removing the side die plate 4 after the poured component is finished.
It is mainly noted that in the above method steps, only one modeling operation is required to be performed at two ends of a beam column of a frame structure after lofting, and repeated modeling is not required, in the process of one modeling, the templates 4 are supported at two ends of the frame structure at the same time, the templates 4 at two ends are supported to be as symmetrical and parallel as possible, and the template fixing pieces are arranged at the edges of the templates 4.
Wherein, foretell template mounting includes: the steel pipe 2 and the battens 3 for reinforcing the formwork 4 and the split bolt 1 for locking the formwork 4 are vertically arranged between the steel pipe 2 and the formwork 4 according to the short sides, and are used for cushioning the formwork 4 to generate a certain construction gap, the split bolt 1 is used for tying the two formworks 4, and it is noted that in the embodiment, the butterfly nut for locking the split bolt 1 is pre-buried in a pouring area before the butterfly nut is not taken out, the butterfly nut 5 for locking the split bolt 1 is locked in a hammering manner in the pouring area after the butterfly nut is not taken out, and the nut shielding of the pouring area after the butterfly nut is covered for attractive appearance.
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 are required to be recorded as H, D, H and D in sequence, and the rule H+D+h+d is less than or equal to 200mm, and it can be understood that the design specification requirement of the settlement joint of the high-rise residence is 200mm-300mm at present, so that the sum of the thicknesses of the template and other fixing devices cannot exceed the width requirement when the template is supported in the settlement joint of the frame structure, otherwise pouring cannot be implemented.
At the end of this scheme, it is necessary to: after the step of secondary demolding, the method further comprises the following steps:
S8: and (3) caulking, removing the split bolt 1, polishing the settlement joint, trowelling the filling mortar, taking out the split bolt 1 after finishing the settlement joint structure, mechanically cutting off the split bolt 1 or polishing by a handheld electric grinder, smearing antirust paint in the settlement joint, and trowelling by waterproof mortar.
The foregoing describes the embodiments of the present invention in detail, but the description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. All equivalent changes and modifications within the scope of the present invention are intended to be covered by the present invention.
