Description
Technical Field
The invention relates to the field of building construction, in particular to a modular mold for pouring a prefabricated stand column.
Background
Along with the popularization of the bridge prefabrication and assembly construction process in urban bridge construction, the bridge construction gradually goes to standardization due to the appearance of a large number of prefabricated stand columns and prefabricated capping beams. The existing upright post processing usually processes an upright post mould meeting the size requirement in a factory after obtaining various data of the upright post, and then processes the upright post by pouring through a concrete mould, when the height of the upright post required by a construction site is different, a plurality of moulds with different heights need to be correspondingly processed, after the upright post processing is finished, the used mould is abandoned because the height of the used mould is not consistent with the height requirement of the upright post of a new construction site, meanwhile, the mould with the corresponding height needs to be processed according to the height of the new upright post when the upright post is produced in the factory, so that a large number of moulds are abandoned after one-time grouting processing, the abandoned quantity of the moulds generated by the factory due to the size is far larger than the natural abandoned quantity of the moulds, on one hand, a large amount of waste of materials is caused, the production cost of the factory is higher, on the other hand, a large amount of time is needed, the processing efficiency of the stand column is low, and the production income of a factory cannot be guaranteed.
Chinese patent No. CN 105442455B discloses a prefabricated upright column casting system for vertical casting of a horizontal formwork and a construction method thereof, including: modularization side form, die block, strutting arrangement and pour the pedestal, wherein, modularization side form and die block are used for constituteing the template system, strutting arrangement is used for supporting modularization side form and die block in order to accomplish horizontal formwork, pour the fixed setting of pedestal and in pouring position department, it is used for the support the die block is so that support after vertical upset the template system, pour the pedestal including be used for with the die block carries out fixed connection structure.
The modularized side die is introduced into the processing of the template system, the original integrated side die structure is split into the modularized side die structures with different lengths along the length direction of the side die, when the height of the side die needs to be changed, the number of the modularized side dies is increased or reduced on the basis of the original side die, the height and the size of the side die are changed very conveniently, the traditional processing mode that one stand column with the same size corresponds to one side die is abandoned, so that the modularized die set with the same cross section size can process a plurality of stand columns with different heights, the processing material is saved, and the production cost is reduced; however, the above invention only processes the columns with the same cross-sectional size and different heights, and when the cross-sectional size of the column changes, the modular side molds with the same size still need to be correspondingly processed, and the processing of the columns with different cross-sectional sizes and different height sizes by one group of modular side molds cannot be realized.
Disclosure of Invention
The invention provides a modular mold for casting a prefabricated stand column, which aims to solve the technical problems that molds for machining the prefabricated stand column in the prior art need to be customized according to the size of the stand column, and a large number of molds are discarded after one-time stand column grouting machining.
In order to achieve the above object, the present invention adopts the following technical solutions.
The utility model provides a modularization mould for prefabricated stand is pour, including die block and the side form of being connected with the die block is dismantled, modular structure's side form is formed by the concatenation of the side form section that length can vary, be equipped with the rainwater groove along its thickness direction on the internal face of side form section, the side form section includes wide template and narrow template, the side form section is formed by the crisscross concatenation of wide template and narrow template, be equipped with the locating component who advances line location to the framework of steel reinforcement on the die block that links to each other with a terminal surface of side form, form complete processing mold after the installation of side form and die block is accomplished, the middle part of processing mold is equipped with the grout groove along its length direction, the framework of steel reinforcement is located the grout inslot and hugs closely with the internal face of side.
In the invention, the side die is of a modular structure and is formed by splicing a plurality of side die sections with different lengths, in order to ensure that the length of the side die can be quickly adjusted according to requirements, in the splicing process of the side die sections, the side die section with the longer length is positioned in the middle of the side die, the side die section with the shorter length is positioned at two ends of the side die section with the longer length, and the side die section connected with the bottom die is the side die section with the shortest length; when the length of the side die needs to be increased according to the preset length, the side die section with longer length can be directly increased at the end part of the side die, and if the length of the increased side die is greater than the preset length, the side die section with shorter end part is removed before the longer side die section is increased; when the length of the side die needs to be shortened according to the preset length, if the shortened length is shorter, the side die section with the shorter end part of the side die is directly removed, if the shortened length is longer, the side die section with the longer middle part of the side die is removed, and then the free shorter side die sections are spliced; the side die sections are connected according to the arrangement mode, and based on the principle of optimized combination, the times of disassembling and splicing the side die sections are the least no matter the length of the side die is shortened or increased. When the mold is grouted to process the stand column, the stand column after grouting generally needs to be subjected to standing aging treatment on an unshielded processing field for about seven days, when concrete in the mold encounters rainwater weather when not being solidified, rainwater can accumulate inside the stand column to cause the solidification process of the stand column to be slow, and the strength and the quality of the processed stand column cannot be guaranteed. According to the invention, the side die consists of a wide die plate and a narrow die plate, the side die and the bottom die are installed to form a complete processing die, the middle part of the processing die is provided with a grouting groove along the length direction of the processing die, and the reinforcement cage is positioned in the grouting groove and clings to the inner wall surface of the side die; when the upright column with a larger cross section needs to be processed, the original narrow template is replaced by the narrow template with a larger size, and the cross section of the upright column can be enlarged.
