In the prior art, the following defects are found in the use of the formwork laying method, namely a strip laying method or a full laying method: 1) the formwork can be divided into a turnover formwork and a disposable formwork. The turnover formwork mainly comprises a plastic (such as polypropylene) formwork, a glass fiber reinforced plastic formwork and a steel formwork, wherein the polypropylene formwork is low in cost, but low in turnover rate and easy to damage, the steel formwork is long in service life, but heavy in weight and high in cost, and the glass fiber reinforced plastic formwork also has the defects of high manufacturing cost, long processing and curing time in winter and the like. Namely, the shuttering made of the single material has more obvious defects. 2) The outer edge of the bottom of the formwork is provided with nail holes, the formwork is fixed on the rib beam formwork through the nail holes by steel nails, and cement putty is scraped at the joint of the formwork and the rib beam in order to prevent slurry leakage at the joint of the formwork. In winter construction, the time required for drying the cement putty is long, and under the comprehensive action of factors such as walking of constructors, vibration of machines and tools, binding load of reinforcing steel bars and the like, the positioning steel nails cannot bear increased load and then bend and deform, so that the displacement of the formwork is obvious, and the slurry leakage phenomenon in the concrete pouring process is serious.
Disclosure of Invention
An object of the utility model is to overcome the shortcoming that exists among the prior art, provide a hollow template for close rib roof beam, the bottom of this hollow template is the frame, the frame with including connecting seat and frame, the frame is connected with rib roof beam template etc. owing to changed the joint direction of mould shell and rib roof beam template to better avoid the erosion to the connecting piece such as putty, the technical scheme of adoption is: the utility model provides a hollow mould shell for close rib beam, the mould shell includes the mould shell body, the mould shell body includes the mould shell upper base to and the peripheral lateral wall of being connected with the upper base, its characterized in that: the hollow shuttering also comprises a frame arranged at the bottom of the peripheral side wall, and the frame and the shuttering body are formed by one-step molding of a die, cooling and demoulding to form the shuttering; the frame has the connecting seat of surrounding peripheral lateral wall bottom, and downwardly extending's frame is established to the connecting seat, and it has the frame perforating hole to open on the frame.
In order to increase the connection strength between the frame and the peripheral side wall and avoid the separation of the frame in a strong stretching state, the frame is also provided with a bougie which extends upwards into the peripheral side wall, and the bougie is provided with a bougie through hole; the bougie through hole is an elliptical hole or a circular hole; the bougie extends upwards from the middle of the connecting seat.
The connector block is an approximately U-shaped connector block, allowing for the need to wrap around the peripheral side wall.
In view of the convenience of processing, the frame is a metal frame, and in particular, an aluminum profile can be used for processing.
In consideration of the requirement of form removal, the included angle between the outline of the cross section of the peripheral side wall and the vertical direction is 5-20 degrees.
The beneficial effects of the utility model reside in that: the hollow shuttering changes the connection mode of the shuttering in the prior art, changes the connection in the horizontal direction into the connection in the vertical direction, and effectively avoids the corrosion of putty and the like; the hollow mould shell is formed by compounding the framework and the mould shell body, so that the impact resistance is improved, the turnover frequency of the mould shell can be increased, the service life is prolonged, and the problem that the framework made of metal and the body made of plastic are easy to separate in a stressed state is solved by the arrangement of the bougie; the hollow shuttering has the advantages of light weight, impact resistance, long service life and convenient installation.
Drawings
FIG. 1 is a schematic view of a formwork structure of the present invention, FIG. 2 is a schematic view of a frame structure, and FIG. 3 is a view from direction A of FIG. 2.
Wherein 1 is the mould shell body, 11 is the mould shell upper base, 12 is the peripheral lateral wall, 2 is the frame, 21 is the frame that the vertical direction extends, 22 is the bougie perforating hole, 23 is the bougie, 24 is the connecting seat, 25 is the frame perforating hole.
Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
The utility model discloses a hollow mould shell for multi-ribbed beam, the mould shell includes mould shell body 1, and mould shell body 1 includes mould shell upper base 11 to and the peripheral lateral wall 12 of being connected with upper base 11, peripheral lateral wall 12 becomes 5-20 degrees contained angles with the vertical direction contained angle.
The formwork further comprises a framework 2 which is arranged at the bottom of the peripheral side wall 12 and vertically extends downwards, the framework 2 and the formwork body 1 form the formwork after one-step molding and cooling demolding by a mold, a frame through hole 25 is formed in the framework 2, and the framework 2 is connected to the rib beam formwork through the frame through hole 25. In this embodiment, the framework 2 of the formwork has a bougie 23, a connecting seat 24 and a frame 21 extending in a vertical direction (vertically downward), and the frame 21 is provided with a frame through hole 25 connected with the rib beam formwork. Referring to the drawings, it can be seen that the connecting seat 24 is a substantially U-shaped seat, and wraps around the bottom of the peripheral side wall 12, the bougie 23 is connected with the connecting seat and extends into the peripheral side wall, a bougie through hole 22 is formed in the bougie 23, and the shape of the bougie through hole 22 can be set as required, such as an elliptical hole or a circular hole.
