Description

Bent cap template supports construction structures

Technical Field

The utility model relates to the field of building construction, in particular to a bent cap formwork support construction structure.

Background

Currently, in municipal, highway bridge construction, a capping beam is one of the most common elements in the substructure. The traditional bent cap supporting system adopts a bottom mould method, a full-space bracket and a combined bracket for construction. When the ground elevation and the ground height are larger, the construction of the full-space support and the combined support is generally adopted, the full-space support and the combined support are most widely applied, and the construction of the cast-in-place concrete structure of the municipal and highway bridges is basically realized. However, no matter the support form adopts a plate buckle, a bowl buckle or a portal frame, the height is limited, and when the height of the bent cap from the ground is lower and the support construction cannot be met, the construction means of a bottom mold method is often needed. The existing bottom die method construction is usually set up in a form of matching concrete pouring after all bricks or parts of the bricks are set up, and although the setting is more efficient, the later-stage dismantling is inconvenient, more materials are wasted, and the secondary use is inconvenient. For this reason, the existing capping beam formwork support structure is to be improved.

The purpose is realized by the following technical scheme.

The utility model provides a bent cap template supports construction structures, this main structure body is brick fetal membrane, and its structural feature lies in the brick fetal membrane includes building block and husky material, and the building block builds the wall body along the edge of the projection scope on bent cap vertical projection ground, and the wall body top that forms matches bent cap bottom surface shape to form the support to bent cap template all around, the wall body central point that the building block enclosed has in advance been used for supporting the pier stud of bent cap, the inside space filling through the compaction husky material except the pier stud of wall body that the building block enclosed, the wall body bottom that the building block formed is equipped with the wash port of reserving all around the interval. Through above-mentioned structure, utilize the mode of block wall body and the combination of filling sand material, can not only realize quick construction and set up, form reliable support to the bent cap template, and the bent cap is pour the construction and is accomplished the back, does quick dismantlement, and building block and sand material all can reuse after dismantling, comparatively economy, environmental protection. The arrangement of the drain holes facilitates water injection and sand compaction in the wall body.

Pier stud is the rectangle for the cross-section in the wall body that the building block formed, and the both sides of wall body and the both sides of pier stud form the laminating, forms the space of filling husky material between the other both sides of wall body and the other both sides of pier stud. The structure is a concrete implementation structure for actual construction, the integral support is reliable and stable, and the requirement of the bent cap formwork support is met.

And concrete surface layers are laid on the wall body formed by the building blocks and the top surface of the sand material, and asphalt felt is laid on the top surfaces of the concrete surface layers. Through this structure, add the concrete surface course and be favorable to the further stable reinforcement of wall body and husky material, through addding the felt, make things convenient for the concrete surface course and pour the drawing of patterns separation operation between the bent cap.

The outside of wall body still includes brick fetal membrane stabilizing support, and brick fetal membrane stabilizing support includes angle steel plate and tie bolt, and the lateral surface of the both sides scute of angle steel plate is equipped with two at least bolted connection seats along angle steel plate length direction interval, the corner department of the wall body all sets up all around of brick fetal membrane the angle steel plate forms the cornerite, passes through between the adjacent angle steel plate around the brick fetal membrane tie bolt connecting seat and nut locking is fixed. Through this structure, further consolidate the brick fetal membrane, guarantee the stability and the reliability of support.

The drain hole of the wall body is formed by lacking building blocks. Through the structure, the building blocks can be placed in the water outlet again according to actual needs, sand materials are prevented from overflowing, the stability of the sand materials in the water outlet is guaranteed, and the supporting reliability is improved.

The utility model has the advantages of simple integral construction structure, material saving, low manufacturing cost, safer construction, more reliable and stable support, easy disassembly and reuse, and is suitable for being used as a bottom die method support structure of a cover beam pouring template or the improvement of similar construction structures.
