Detailed Description
The present invention will be further described with reference to the following examples.
As shown in fig. 1 and 2, the invention provides a special mold for preparing a concrete moon door, which is provided with a finished component cavity 4, wherein the periphery of the finished component cavity 4 is respectively provided with an upper side mold 1, two side molds 5, a bottom side mold 10 and a door opening reserved special-shaped side mold 6; the finished component cavity 4 is a reserved cavity of a semi-finished product after the side die is assembled and produced for a single time; the special mould is also provided with a threaded steel sleeve 2 for hoisting, a bar penetrating grouting connecting hole 3, a special-shaped side formwork supporting steel beam 8 and a base connecting reserved corrugated pipe 9.
As shown in figure 1, the periphery of the die is provided with local upper-reverse and stepped settlement, the deformation of the die in the production procedure can be reduced by splicing the die, the demoulding of the finished product can be facilitated, and the integrity of the finished product after demoulding is ensured when the finished product does not reach 100%.
The used mould of production adopts bolted connection seamless concatenation, and door opening reservation abnormal shape side forms 6 and abnormal shape side forms support adding of girder steel 8 establish in order to prevent that door opening reservation abnormal shape side forms from receiving external stress such as concrete and taking place to warp when producing, and the stability that can strengthen the special-shaped mould is established in adding of abnormal shape side forms support girder steel. The door opening is reserved with a special-shaped side mold 6 and peripheral side molds, and the shape and the size can be customized according to the specific requirements of customers on the moon door.
Compared with a wooden template, the steel mold has the characteristics of high precision, repeated utilization and the like, can meet the requirement of producing various shapes, is not limited to single sizes of inner circle and outer square and the like, can be produced in batch, can be specially customized for a special project, and can be used for designing the sizes, the appearance shapes and the like according to the special requirements of the project. The precision of the special-shaped corners of the die can be guaranteed by adopting a 5mm steel plate for laser blanking, and the mechanical welding seamless treatment is adopted, so that the precision of the processed die is guaranteed, and the problem of material leakage caused by seam leakage caused by welding leakage can be solved.
As shown in figure 4, the production method of the concrete moon gate provided by the invention is characterized in that production is carried out according to a novel assembly type concrete member process, the whole member is divided into two parts by a side central axis and adopts a reverse beating process, M20 80 threaded steel sleeves are pre-embedded at three positions on the front surface of the member (the stress level and the uniformity during lifting are ensured), two M20 200 threaded steel sleeves are pre-embedded at two positions on an upper side die of the member (for vertical lifting installation and use), the whole member is spliced by two members produced in a split mode (a splicing mode is that holes are reserved at 50 mm-100 mm positions on the inner sides of a peripheral side die and a doorway arc side die, the two members are aligned and spliced to insert reinforcing steel bars during splicing, a rubber plug is used after high-strength grouting is used, and a horse tooth groove type staggered splicing grouting is carried out at the top of the member, so that the horizontal distortion can be effectively solved.)
Except the dowel bar connecting hole, other joint surfaces of the whole joint surfaces of the two members are in a hollow state, and most joint surfaces of the two members are in the hollow state, so that the concrete is saved, and meanwhile, space is reserved for local deformation caused by self load of the members. The component is supported and fixed by pre-buried reservation of a corrugated pipe, and is grouted and connected by connecting pre-buried steel bolts of a ground bottom plate (when high-strength grouting material is used and the grouting material does not reach the specified strength, a front three-point pre-buried M20X 80 threaded steel sleeve is connected with an inclined support for temporary fixation.)
