Description

Technical Field

[0001] The utility model relates to the technical field of basement building construction, in particular to a basement outer wall formwork frame. Background Art

[0002] At present, underground space is being used more and more widely. Basement anti-leakage is of great significance to ensuring the quality of housing. The underground exterior wall is a key part. At present, the construction quality of the basement exterior wall generally has problems such as insufficient vibration of the wall concrete, poor quality of the horizontal construction joints, and loose concrete at the water-stop steel plate. These quality defects lead to basement leakage, causing high repair, grouting and even reinforcement costs, which have a significant impact on the cost, quality and construction period of the project. Therefore, our company has summarized the "basement exterior wall deformation compensation method formwork anti-seepage and anti-crack frame" in long-term engineering practice, tightening and reinforcing the formwork at the horizontal construction joint of the exterior wall, eliminating the adverse effects of the initial deformation of the supporting steel pipe, and transmitting the supporting force obliquely to the horizontal construction joint through the water-stop bolts, supporting steel pipes, and the inclined surface of the wooden wedge, which greatly enhances the quality of the formwork at the key position. Utility Model Content

[0004] In order to solve the above-mentioned existing technical problems, the utility model adopts the following scheme: a basement exterior wall formwork frame, including an upper formwork and a lower formwork, a formwork for pouring is arranged on the upper formwork, waterstop bolts are inserted in the formwork, and the waterstop bolts are symmetrically clamped with horizontal steel pipes and wooden wedges on both sides of the formwork. The wooden wedges are designed in a triangular shape, and a serrated slope is provided on the inclined surface of the wooden wedge. The serrated slope is in compression contact with the horizontal steel pipe, and the plane of the wooden wedge is in close contact with the formwork, and the lower formwork supports the upper formwork through the diagonal steel pipe.

[0005] Preferably, the outer side of the horizontal steel pipe is wrapped with an arc-shaped clamp.

[0006] Preferably, the teeth of the sawtooth slope are inclined upward.

[0007] Preferably, the lower supporting formwork is provided with supporting feet, which are in contact with the bottom of the diagonal supporting steel pipe.

[0008] Preferably, the wooden wedges are located on both sides of the horizontal construction joint, and the tips of the triangular wooden wedges are inserted downwards.

[0009] Preferably, supporting wooden planks are arranged around the template.

[0010] Beneficial effects: The utility model adopts the above technical solution to provide a basement external wall formwork frame with the following effects: first, by tightening and reinforcing the formwork at the horizontal construction joint of the external wall, the adverse effect of the initial deformation of the supporting steel pipe is eliminated, and the supporting force is transmitted obliquely to the horizontal construction joint through the force transmission path of the water stop bolt, the supporting steel pipe, and the inclined surface of the wooden wedge, which greatly enhances the formwork quality at the key position, avoids the problems of slurry leakage and mold expansion, and prevents the deformation of the formwork frame;

[0011] Secondly, by designing wooden wedges to press the formwork and steel pipes, during construction, the cross-section of the wooden wedge is triangular, and the angle of the wedge slope is calculated so that the supporting force of the water stop bolt below is transmitted from the slope to the horizontal joint, bearing the lateral pressure of the concrete. The upward-inclined serrations of the wooden wedge have a reverse anti-slip shape to prevent the wooden wedge from being squeezed and sliding as the lateral pressure increases during the concrete pouring process.

[0015] like Figure 1-3 A basement external wall formwork frame is shown, comprising an upper formwork 1 and a lower formwork 2, wherein a casting formwork 3 is arranged on the upper formwork 1, water stop bolts 4 are inserted into the formwork 3, horizontal steel pipes 5 and wooden wedges 6 are symmetrically clamped by the water stop bolts 4 on both sides of the formwork 3, the wooden wedges 6 are triangular in design, and a sawtooth bevel 7 is arranged on the inclined surface of the wooden wedge 6, the sawtooth bevel 7 is in extrusion contact with the horizontal steel pipe 5, the plane of the wooden wedge 6 is in close contact with the formwork 3, and the lower formwork 2 supports the upper formwork 1 through a diagonal steel pipe 8;

[0016] The specific upper and lower supporting forms 1 and 2 are supported and stabilized by the diagonal steel pipe 8. The upper supporting formwork 1 includes formworks 3. There are gaps between the formworks 3 for concrete pouring. The water stop bolt 4 passes through the middle of the formwork 3 and is fixed and stabilized by the horizontal steel pipe 5 and the wooden wedge 6. The formwork 3 is tightened and reinforced to eliminate the adverse effects of the initial deformation of the horizontal steel pipe 5. The supporting force is transmitted through the force transmission path of the serrated inclined surface 7 of the water stop bolt 4, the horizontal steel pipe 5 and the wooden wedge 6, and the supporting force is obliquely transmitted to the horizontal construction joint between the wooden wedges 6, which greatly enhances the formwork quality at key positions, avoids leakage and mold expansion problems, and prevents the formwork frame from deforming. At the same time, through the special design of the wooden wedge 6, the cross-section of the wooden wedge 6 is triangular, and the angle of the wedge-shaped inclined surface is calculated so that the supporting force of the water stop bolt 4 below is just transmitted from the inclined surface to the horizontal joint between the formworks 3, and the upward inclined serrations of the wooden wedge 6 that bears the lateral pressure of the concrete have a reverse anti-slip shape to prevent the wooden wedge 6 from being squeezed and sliding as the lateral pressure increases during concrete pouring.

[0017] Furthermore, the outer side of the horizontal steel pipe 5 is wrapped with an arc-shaped clamp 9 , and the horizontal steel pipe 5 is wrapped by the arc-shaped clamp 9 to achieve a stabilizing effect, thereby preventing the horizontal steel pipe 5 from shifting and causing deformation of the template 3 .

[0018] Furthermore, the teeth of the serrated slope 7 are inclined upward, and the serrated slope 7 is arranged on the wooden wedge 6, which is used to press the formwork 3 and the horizontal steel pipe 5 to maintain the stability of both, and prevent the formwork 3 from being deformed due to excessive pressure during pouring. At the same time, the upward inclination of the serrated teeth has a reverse anti-slip effect, preventing the horizontal steel pipe 5 from sliding down under force.

[0019] Furthermore, the lower formwork 2 is provided with a support foot 10, which contacts the bottom of the diagonal support steel pipe 8. The support foot 10 of the lower formwork 2 is used to prevent the diagonal support steel pipe 8 from sliding under force during the support process, thereby causing deformation of the template 3.

[0020] Furthermore, the wooden wedges (6) are located on both sides of the horizontal construction joint, and the tip of the triangular wooden wedge 6 is inserted downward. The wooden wedge 6 is inserted downward so that its inclined surface contacts the horizontal steel pipe 5, and the plane of the wooden wedge 6 contacts the formwork 3. The wooden wedge 6 is pressed by the horizontal steel pipe 5 to tighten the formwork 3.

[0021] Furthermore, supporting wooden slats 11 are arranged around the formwork 3, and the supporting wooden slats 11 are arranged around the formwork 3 to assist in supporting the formwork 3. The supporting wooden slats 11 and the horizontal steel pipes 5 can further stabilize the formwork 3. After the formwork 3 is supported, concrete is poured inwardly, and a waterstop steel plate is arranged. The concrete on both sides of the waterstop steel plate are vibrated separately to eliminate the vibration-isolating effect of the waterstop steel plate, reduce wall cracking and water leakage, and improve the surface quality.
