Description
Technical Field
[0001] The utility model belongs to the technical field of prefabricated wall production moulds with windows, and in particular relates to an EMC system prefabricated wall window tongue and groove production mould. Background Art
[0002] The EMC prefabricated concrete structure technology system is a "non-equivalent cast-in-place construction theory" proposed based on the principle of force to solve the technical difficulties in the implementation of prefabricated concrete structures. In recent years, with the acceleration of the national residential industrialization process, a large number of prefabricated concrete structure houses have been built and put into use. This model has a fast construction speed, saves labor costs, and greatly improves the quality of construction.
[0003] When EMC system prefabricated walls involve prefabrication of walls with windows, it is necessary to set up window templates. Traditional window templates are four-sided flat templates with four fixed corners. In recent years, they have been designed as window tongue and groove designs, so that the window opening on the outside of the window structure of the prefabricated wall is larger than the window opening on the inside, forming a high and low tongue and groove in the window, which can improve the waterproof performance of the exterior wall with windows. In addition, in order to reduce the weight of the wall and anchor the steel bars of the lower building structure, several corrugated pipes are also pre-buried on the lower side of the window. In the prior art, the following problems exist during the construction of the window tongue and groove structure: on the one hand, since the upper end of the corrugated pipe needs to be docked with the window template, in order to adapt to the tongue and groove structure, the upper end of the corrugated pipe needs to be cut according to the shape of the window tongue and groove, which increases the work and makes the construction troublesome; on the other hand, since the corrugated pipe body is relatively soft, the end is not tightly fitted with the tongue and groove template, and the concrete is easy to fall into the corrugated pipe during pouring, and secondary cleaning is required later.
[0004] In the prior art, the window tongue and groove of the wall mold interferes with the corrugated tube reserved inside the wall below the window, and the upper end of the corrugated tube does not fit well with the tongue and groove mold. As a result, when the mold is removed, the concrete quality around the fitting position of the corrugated tube and the window tongue and groove is poor and easy to fall off, thereby affecting the quality and aesthetics of the prefabricated wall. Utility Model Content
[0005] The technical problem to be solved by the utility model is that the connection node between the corrugated pipe and the window enterprise template in the wall template with windows has poor matching degree, is easy to fall into the concrete and has poor hole forming.

[0007] A mold for making a tongue-and-groove of a prefabricated wall window of an EMC system, comprising an inner mold for a window and a reserved hole mold, wherein:
[0008] The window inner mold is enclosed by four surface molds, each of which is composed of an outer plate and an inner plate. The outer plate and the inner plate are fitted and fixed on the side away from the center of the window, and the angle positions of the four surface molds are fixed;
[0009] The reserved opening mold is composed of a corrugated pipe, supporting ribs and a tongue and groove module. The supporting ribs are installed inside the corrugated pipe. The lower end of the tongue and groove module is connected to the upper end of the corrugated pipe, and the upper end is connected to the window inner mold. The supporting ribs are fixedly connected to the tongue and groove module, and the lower end of the corrugated pipe is connected to the lower side template of the wall.
[0010] Compared with the prior art, the utility model adopting the above structure has the following beneficial effects:
[0011] The utility model adopts a tongue and groove module to connect with the window inner mold, strengthens the supporting force of the node position of the reserved hole template and the window template, and thus improves the forming hardness of the hole.
[0012] As a preferred embodiment, a further technical solution of the above structure is:
[0013] The tongue and groove module is cylindrical, and its lower end is tightly fitted with the bellows sleeve, and the front and rear parts of its upper end are arranged as a high and low staggered structure, wherein the high side is fitted with the lower surface of the inner plate, and the low side is fitted with the lower surface of the outer plate.
[0014] The beneficial effects obtained by the above features are as follows: this solution makes the reserved hole mold and the window mold well matched, can achieve the effect of avoiding leakage of slurry, and has a good tongue-and-groove forming effect and a beautiful and standardized appearance.
[0015] The upper end of the support rib is a threaded connection end, and the tongue and groove module is provided with a through hole corresponding to the upper end of the support rib, and a groove is provided on the upper side of the through hole, a nut is installed in the groove, and the nut is screwed and fixed to the threaded connection end; a threaded hole is provided on the upper side of the tongue and groove module, and the tongue and groove module is bolted to the inner plate and / or the outer plate.
[0016] Beneficial effects obtained by the above features: This embodiment facilitates the connection and installation of the mold structure and facilitates the template construction.
[0017] The side of the supporting rib abuts against the inner wall of the corrugated tube.
[0018] The beneficial effects obtained by the above-mentioned features are as follows: the strength of the corrugated pipe is strengthened by the support ribs, thereby avoiding deformation due to concrete pressure and the resulting problem of poor hole forming. BRIEF DESCRIPTION OF THE DRAWINGS
