Fixing structure for constructional engineering formwork

Abstract

The utility model discloses a fixing structure for a constructional engineering formwork. The fixing structure comprises two steel plates which are symmetrically arranged. The two main screw rods are symmetrically arranged and movably penetrate through the two ends of the two steel plates; connecting screw holes are formed in the middle area of the inner side face of the steel plate at equal intervals, limiting ring grooves are formed in the middle area of the outer side face of the steel plate, and the limiting ring grooves and the connecting screw holes are concentrically arranged. An abutting assembly penetrates through the connecting screw hole, one end of the abutting assembly is located outside the steel plate, and the end face of the other end of the abutting assembly is clamped in the limiting ring groove. The pressing assembly is arranged in the middle area of the steel plate, so that flexible fixed-point pressing can be conducted according to the specific shape of the mold, and the problem that in a traditional fixing mode, the pressing force is insufficient due to the fact that the steel plate cannot be tightly attached to the non-planar area in the middle of the mold is effectively solved; therefore, the fixing structure can accurately identify and lock the force bearing point when facing a complex mold form.

Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building engineering, specifically related to a fixed structure for building engineering template. BACKGROUND

[0002] In the construction process of building engineering, foundation pouring is often needed, and in order to ensure the shape and quality of the foundation, a template is needed to shape the foundation to be poured, so a special fixing structure is needed to support and limit.

[0003] The widely used mold fixing structure in the current construction industry generally adopts a clamping method to achieve sleeving and limiting during the positioning and limiting of the mold. This fixing method can usually ensure that the stress points are evenly distributed on the surface of the entire mold, thereby providing stable support and fixing effect in most cases. However, with the increasing complexity and diversification of building design, the shape of the mold also becomes more and more rich, especially when the middle part of the mold presents a non-planar structure, the traditional fixing method is not up to the task;

[0004] The middle part of the non-planar mold often contains various curves, slopes or uneven shapes. These special design elements make it difficult for conventional fixing structures to achieve close fitting. Because the stress points cannot be evenly distributed, the mold may shift, loosen or even deform when stressed, thereby failing to achieve the desired tight fixing effect. This not only affects the performance of the mold, but also may pose a potential threat to the quality and safety of building engineering. SUMMARY

[0005] The utility model aims at providing a fixed structure for building engineering template to solve the problem of the existing fixing structure being unable to tightly fix the non-planar mold.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a fixed structure for building engineering template, comprising two steel plates arranged symmetrically; two main screw rods arranged symmetrically, the main screw rods being movably penetrated through both ends of the two steel plates; a connecting screw hole is equally provided in the middle area of the inner side surface of the steel plate, and a limiting ring groove is provided in the middle area of the outer side surface of the steel plate, the limiting ring groove being concentrically arranged with the connecting screw hole; a tight fitting assembly is penetrated through the connecting screw hole, one end of the tight fitting assembly being outside the steel plate, and the other end being clamped in the limiting ring groove, thereby avoiding separation of the tight fitting assembly, and in the process of tightly fixing the mold, the mold surface can be tightly fixed by rotating the tight fitting assembly, avoiding loosening.

[0007] Preferably, the abutting assembly comprises an abutting stud screwed into and penetrating the connecting hole, and a threaded ring is screwed onto the end of the abutting stud in the internal region of the steel plate, the threaded ring abuts the limiting ring groove, thereby achieving installation of the abutting stud and avoiding falling off of the abutting stud.

[0008] Preferably, the thickness of the threaded ring is abutted with the internal depth of the limiting ring groove, and the threaded ring is flush with the end surface of the abutting stud, so that when the abutting stud is not used, the abutting stud can be placed in the limiting ring groove as a whole with the threaded ring, and will not protrude to the internal region of the steel plate.

[0009] Preferably, the two ends of the steel plate are provided with an adjusting groove for the main screw rod to move and penetrate, the two ends of the main screw rod are provided with threads, and a limiting nut is screwed into the threaded region, and the limiting nut at the two ends of the main screw rod abuts the internal side surface of the steel plate, thereby achieving fixation of the mold.

[0010] Preferably, the internal diameter of the adjusting groove is greater than or equal to the external diameter of the main screw rod, and a spacing is left between the adjusting groove and the connecting hole.

[0011] Preferably, the two ends of the steel plate are further provided with a butt joint hole, a connecting assembly is screwed into the butt joint hole, the connecting assembly comprises two tightening portions and a connecting stud for fixing the two tightening portions, through the arrangement of the connecting assembly, the two steel plates can be connected, thereby achieving the purpose of splicing and assembling, achieving fastening of the large mold, and in the connection, the connecting stud provides a force point.

[0012] Preferably, the tightening portion is threadedly connected with the butt joint hole, and at least three butt joint holes are provided at the end surface of the steel plate, thereby ensuring stability after connection.

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] Through the arrangement of the utility model, the abutting assembly is arranged in the middle region of the steel plate, thereby achieving flexible and fixed-point abutting according to the specific shape of the mold, effectively solving the problem of insufficient abutting force caused by the fact that the steel plate cannot closely adhere to the middle non-planar region of the mold in the traditional fixing mode, and the introduction of the abutting assembly enables the fixing structure to accurately identify and lock the stress point when facing a complex mold shape, so that the mold will not be deviated or loosened during the stress process, the mold is fixed in all directions and without dead angle through the fixed-point abutting mode, the stability and reliability of the fixation are greatly improved, the mold can be normally used for pouring, and the pouring quality problem caused by improper fixation of the mold is effectively avoided.
