Description

TECHNICAL FIELD

[0001] The utility model relates to a support technology field especially points to an adjustable support structure for supporting bent cap formwork. BACKGROUND

[0002] The bent cap is a component commonly used on the door and window hole of the wall of the masonry structure house, which is used to bear the dead weight of the masonry above the top surface of the hole and the load transmitted from the upper floor beam plate. The construction of the bent cap mainly includes the following steps: 1. Preparation stage: according to the structural drawing, the detailed size and reinforcement requirement of the bent cap are determined to ensure that the cross-sectional size, reinforcement distance and other parameters of the bent cap meet the design requirements. 2. Formwork installation: the formwork installation of the bent cap is the most critical step in construction, the main keel is reinforced by using a standardized clamp, and attention should be paid to the firmness during the formwork installation to ensure the stability of the structure after the concrete pouring. 3. Steel bar binding: according to the design requirement, the steel bar is bound to ensure that the spacing and length of the steel bar meet the specification. The binding quality of the steel bar directly affects the bearing capacity of the bent cap. 4. Concrete pouring: after the formwork and steel bar are prepared, the concrete is poured. During the pouring process, attention should be paid to the uniform vibration to ensure the compactness of the concrete. 5. Maintenance: after the pouring is completed, appropriate maintenance is needed to prevent the concrete from cracking due to the rapid evaporation of water, and the method of pouring water or covering moisture-retaining materials is usually used for maintenance.

[0003] Among them, the quality of the formwork not only determines the quality of the bent cap pouring, but also affects the construction safety, and also has an impact on the construction environment of the construction site. The conventional use method of the bent cap formwork is to place a support rod at the bottom of the bent cap first, then install the bent cap formwork at the wall at both ends of the bent cap, and use the support rod to support the bent cap formwork, so that the load of the bent cap formwork is transmitted to the ground through the support rod. The support rod needs to be used in cooperation with several support rods, and the support rod needs to be fixed with the ground, which not only makes it difficult to disassemble, circulate and assemble, but also blocks the passing space below the bent cap.

The above-mentioned invention patent also discloses a construction method of the portable adjustable lintel formwork support structure, which comprises the following steps: step 1: erecting a wall and reserving a supporting groove; step 2: inserting a supporting steel bar into the supporting groove; step 3: installing the supporting structure on the wall and the supporting steel bar; step 4: fixing the supporting structure; step 5: fixing the clamping plate; step 6: installing the lintel formwork; and step 7: pouring the lintel on the lintel formwork. The application has the effect of facilitating the rapid erection of the support structure of the lintel formwork.

[0005] However, through test verification and problem analysis, it is found that the technical solution provided by the above-mentioned invention patent has the following deficiencies: first, the inclined supporting groove needs to be prefabricated on the wall at both sides of the lintel in advance, then the supporting steel bar is inserted into the supporting groove, and then the adjusting sleeve of the supporting structure is sleeved on the supporting steel bar, so that the prefabrication of the supporting groove, the installation and fixation of the supporting steel bar, and the assembly of the supporting structure and the supporting steel bar all have special requirements; second, since the supporting structure comprises vertically arranged supporting rods and linkage rods, obliquely arranged supporting feet, and transversely arranged parallel rods, the passing space below the lintel will be occupied, thereby affecting the passing performance.

[0006] In summary, there is an urgent need to design a lintel formwork support structure which occupies less space and is convenient to disassemble and assemble.
