Problems solved by technology

However, the mold box of this structure is not easy to assemble and fix, and the structural concrete is easy to be damaged when dismantled. The concrete is easy to collapse if it is dismantled early, and the geometric size of the hole is difficult to meet the design requirements; it will be difficult to dismantle it if it is dismantled late, especially the bottom of the hole and the inner corner formwork of the hole. If the dismantling is not clean, the quality of the secondary concrete grouting will be affected and the labor cost of dismantling will increase

Embodiment 1

[0020] Such as Figures 1 to 3 As shown, the formwork structure used to reserve embedded bolt holes for equipment foundation in cast-in-place concrete includes a reserved hole box composed of fixed connections of steel plates 1 at the bottom and surroundings, and the thickness of steel plates 1 is 5mm. The ground, bottom and surrounding steel plates 1 are fixedly connected by welding, which is convenient and quick to assemble through welding, and the overall structural strength is good. The reserved hole box is fixedly installed in the concrete foundation 2, and the inside of the reserved hole box is used for pouring internal concrete 3. The concrete 3 is used to fix the anchor bolts 4. Specifically, the reserved hole box is a conical body with a small upper opening and a large lower opening, surrounded by four steel plates 1 welded, the upper opening and the lower opening are both rectangular, and the bottom plate and The lower ends of the four steel plates 1 are welded and f...

Embodiment 2

[0022] Such as Figures 1 to 3 As shown, on the basis of embodiment 1, the outer wall of the steel plate 1 around the reserved hole box is fixedly connected to the outer pull-out rod 5 by welding, the outer pull-out rod 5 is threaded steel, and the outer pull-out rod 5 is fixed to the concrete foundation 2 connection, improve the pullout performance of the reserved hole box, so that it can be firmly installed in the concrete foundation 2, and further, one end of the outer pullout rod 5 is fixedly connected with the outer wall of the steel plate 1 around the reserved hole box by welding, and the other end Extending into the concrete foundation 2 and upturning, so that one end of the outer pull-out rod 5 is lower than the other end, forming a barb-like pull-out structure, which further improves the pull-out performance of the reserved hole box and ensures that the reserved hole box It is installed in the concrete foundation 2 more stably, so that the reserved hole box and the co...

Embodiment 3

[0024] Such as Figures 1 to 3 As shown, on the basis of Example 1, the inner wall of the reserved hole box is fixedly provided with an inner pull-out rod 6 and / or an anti-slip pattern 7, the inner pull-out rod 6 is welded and fixed to the inner wall, and the anti-slip pattern 7 can be integrated with the steel plate 1 Forming, the inner pull-out rod 6 is screw steel, that is, the inner pull-out rod 6 or the anti-skid pattern 7 can be fixed separately on the inner wall, or the inner pull-out rod 6 and the anti-skid pattern 7 can be fixed on the inner wall at the same time, and the internal concrete can be lifted 3's anti-pullout performance, so that the internal concrete 3 is firmly arranged in the reserved hole box, and further, when the inner anti-pullout rod 6 is fixedly installed on the inner wall, one end of the inner anti-pullout rod 6 and the steel plate around the reserved hole box The inner wall of 1 is fixedly connected, and the other end can extend into the inner co...

Abstract

The invention relates to the technical field of building construction, and discloses a template structure for reserving an equipment basic embedded bolt hole in cast-in-place concrete. The template structure comprises a reserved hole box formed by fixedly connecting bottom and peripheral steel plates, wherein the reserved hole box is fixedly arranged in a concrete base; the inside of the reservedhole box is used for casting internal concrete; the internal concrete is used for fixing a foundation bolt. By adopting template structure, a mounting hole for an embedded bolt can be reserved directly in the concrete base, and the reserved hole box does not need to be removed and is fixedly connected with the concrete base for whole use; moreover, sufficient connection strength can be ensured, and stable connection between the reserved hole box and the concrete base as well as between the internal concrete and the reserved hole box can be realized.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a formwork structure for reserving pre-embedded bolt holes for equipment foundations in cast-in-place concrete. Background technique [0002] Bolt holes are reserved for cast-in-place concrete. The traditional reserved bolt holes are generally made of wood planks or wooden beams plus 12mm thick plywood to form a mold box with a geometric shape required by the design. After the initial setting of the concrete pouring, the mold box is removed. However, the mold box of this structure is not easy to assemble and fix, and the structural concrete is easy to be damaged when dismantled. The concrete is easy to collapse if it is dismantled early, and the geometric size of the hole is difficult to meet the design requirements; it will be difficult to dismantle it if it is dismantled late, especially the bottom of the hole and the inner corner formwork of the hole. If the demo...
