Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of floor beam pouring formwork, in particular to floor beam pouring formwork. BACKGROUND

[0002] The traditional floor beam pouring formwork is composed of a wood board and a wooden frame fixed by a screw rod and a bolt. However, the connection of the floor beam is a special-shaped structure, so that the beam-side wood board above many floors cannot be installed with a pull-fixing structure, resulting in that the formwork cannot be pulled together, and thus the formwork explosion occurs. SUMMARY

[0003] The utility model mainly aims at providing floor beam pouring formwork to solve the technical problem that the beam-side wood board above the floor cannot be installed with a pull-fixing structure in the prior art.

[0004] In order to achieve the above-mentioned purpose, the utility model provides floor beam pouring formwork, and the technical scheme is as follows:

[0005] The floor beam pouring formwork comprises a first wood board at the bottom of a floor, a second wood board at the inner side of a beam, a third wood board at the outer side of the beam, and a first pull-fixing structure for fixing the second wood board and the third wood board, wherein the first pull-fixing structure comprises a first screw rod, and further comprises a second pull-fixing structure, wherein the second pull-fixing structure comprises: a concrete block fixed to the first wood board and connected with a steel bar at the inner side of the first wood board; a nut embedded in the concrete block; and a plug groove at the bottom of the concrete block matched with the steel bar; and a second screw rod threadedly connected with the nut at one end and connected with a bolt at the other end through the third wood board.

[0006] In the floor beam pouring formwork of the utility model, the second pull-fixing structure can be connected with the steel bar through the concrete block, so that the upper part of the third wood board at the outer side is pulled together with the steel bar, and the steel bar can bear the horizontal load of the concrete at the upper part of the structural beam, so that the reinforcing effect of the formwork is significantly improved; in addition, the second pull-fixing structure is simple in structure, easy to process and manufacture and install, and can work together with the first pull-fixing structure to effectively prevent the formwork explosion.

[0007] As a further improvement of the floor beam pouring formwork, the bottom of the concrete block is connected with the first wood board through screws at both sides of the plug groove. In this way, the installation of the concrete block and the disassembly of the first wood board after pouring are facilitated, and the connection strength of the concrete block, the steel bar and the first wood board is high, so that the reinforcing effect of the formwork is improved.

[0008] As a further improvement of the floor beam pouring formwork, the second screw rod is 40-80 mm away from the center of the first wooden board.

[0009] As a further improvement of the floor beam pouring formwork, the concrete block is connected to the steel bars closest to the third wooden board on the inner side of the first wooden board. Thus, the length of the second screw rod can be shortened under the premise of good pull effect on the third wooden board, thereby saving material cost.

[0010] As a further improvement of the floor beam pouring formwork, the first pull fixing structure and the second pull fixing structure are arranged at a distance of 300-500 mm in the horizontal direction. Thus, the formwork has good reinforcing effect.

[0011] As a further improvement of the floor beam pouring formwork, it further comprises a vertical fixing assembly arranged on the outer side of the second wooden board and the third wooden board, the vertical fixing assembly comprising vertically arranged vertical pipes with first through holes; a horizontal fixing assembly arranged on the outer side of the vertical fixing assembly, the horizontal fixing assembly comprising horizontally arranged horizontal pipes with second through holes; wherein the vertical pipes and the horizontal pipes comprise steel pipes and concrete filled in the steel pipes; and the first screw rod is fixed by bolts after passing through the first through holes, the second through holes, the second wooden board and the third wooden board. Thus, the pipe body with a steel pipe-concrete structure has obvious advantages in structural strength, stability, service life, construction efficiency, safety and environmental protection compared with wooden frames, especially in large-scale and complex construction, the steel pipe-concrete formwork can provide higher bearing capacity, impact resistance and longer service life, reducing the dependence on wood resources.

[0012] As a further improvement of the floor beam pouring formwork, the steel pipe is a square steel pipe; thus, it is cheap, easy to obtain and convenient to use. The concrete filled in the steel pipe is C20 fine stone concrete; the C20 fine stone concrete refers to concrete with a strength of C20 and a maximum particle size of coarse aggregate of not more than 15 mm, thus the obtained pipe body has higher impact resistance.

[0013] As a further improvement of the floor beam pouring formwork, the vertical pipes and the horizontal pipes are spliced by short sections and sleeves; thus, the pipe body of corresponding size can be assembled and used according to the pouring volume, improving resource utilization and reducing material cost; the splicing by sleeves not only is convenient to operate, but also has high strength, high bearing capacity and high impact resistance.

[0014] As further improvement of the floor beam pouring formwork, the vertical pipe has an arrangement interval of 50-150mm, and the horizontal pipe has an arrangement interval of 200-400mm.
