Abstract
The utility model provides a foundation trench pouring connection structure, wherein a foundation trench is reserved on concrete, and the foundation trench pouring connection structure is characterized in that: be provided with on the foundation trench cell wall and exempt from to tear open the template, exempt from to tear open and have protruding structure on the template, protruding structure is to the protruding setting of foundation trench cell wall, has pour secondary grout concrete in the foundation trench, and protruding structure can make the concrete face of secondary grout concrete form natural matte. The utility model can ensure the forming of the foundation trench and simultaneously ensure the bonding of the contact surface of the secondary grouting concrete in the foundation trench and the primary concrete.
Description
Technical Field
The utility model relates to the technical field of constructional engineering concrete construction, in particular to a foundation trench pouring connection structure.
Background
In the building engineering, a large equipment foundation needs to be tightly connected with concrete, so that the functions of fixing equipment and transferring load can be achieved. Especially, the foundation of the large power equipment is large in load and vibration load, and the operation of the large power equipment is directly influenced by the connection of the foundation and the concrete. The connection method of the large power equipment foundation and the concrete is that a foundation groove is reserved during concrete pouring, when equipment is installed, a foundation fixing screw is positioned, fixed and installed in the foundation groove, and then secondary grouting is conducted on the foundation groove. The foundation trench adopts big end down's wedge structure more, and foundation trench plane length and width size 200 ~ 300mm, degree of depth 700 ~ 1000mm, adopts the plank sheathing to piece together the wedge groove structure more when concrete placement at present. However, this method has several problems: 1. the template is difficult to remove, the size of the plane of the groove is small, the depth is large, the operation space is small, and the template, particularly the lower template, is difficult to remove completely; 2. the groove surface scabbling degree of difficulty is big, because of the construction space is very little, the processing of scabbling is hardly carried out on basic groove surface, influences the contact surface bonding of secondary grout concrete and first stage concrete to influence the biography power between equipment foundation and the concrete.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model aims to provide a foundation trench pouring connection structure. The utility model can ensure the forming of the foundation trench and simultaneously ensure the bonding of the contact surface of the secondary grouting concrete in the foundation trench and the primary concrete.
In order to solve the technical problems, the utility model is realized by the following technical scheme:
the utility model provides a connection structure is pour to basic groove, has basic groove in advance on the concrete, and the basic inslot is equipped with the fixing bolt on large-scale power equipment basis, its characterized in that: be provided with on the foundation trench cell wall and exempt from to tear open the template, exempt from to tear open and have protruding structure on the template, protruding structure is to the protruding setting of foundation trench cell wall, has pour secondary grout concrete in the foundation trench, and protruding structure can make the concrete face of secondary grout concrete form natural matte.
Further: the disassembly-free template is formed by splicing a plurality of steel wires to form a net structure, and the steel body of each steel wire is bent to form the protruding structure.
Further: the protruding structures are arranged in a wedge shape or a square shape.
Further: the protruding structures are arranged on the steel wire at intervals.
Further: the size of the disassembly-free template is matched with the size of the groove wall of the foundation groove.
Compared with the prior art, the utility model has the following advantages and beneficial effects:
the template in the foundation trench is a non-dismantling template, so that the template is not required to be dismantled, and the construction quality of the foundation trench is prevented from being influenced because the template is not dismantled thoroughly; the non-dismantling formwork is provided with a convex structure, so that the concrete surface of the secondary grouting concrete forms a natural rough surface without chiseling. The formwork removal and the chiseling construction in the narrow space of the foundation trench are avoided, and the connection between the secondary grouting concrete of the foundation trench and the primary concrete of the foundation trench can be ensured, so that the connection between the equipment foundation and the concrete and the reliable force transmission are ensured.
