Technical Field
The utility model belongs to the technical field of the construction technology and specifically relates to an used building mould shell of close rib superstructure construction is related to.
Background
The multi-ribbed floor system composed of thin plates and rib beams with small intervals has the advantages of wide application range, material saving, rapid construction, reduction of self weight of the building and the like, and is widely applied to the construction and construction of underground and multi-storey and high-rise buildings with large span, large load and large space.
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. For the turnover formwork, three types of plastic (such as polypropylene) formworks, glass fiber reinforced plastic formworks and steel formworks are mainly adopted, and the plastic formwork is low in cost, low in turnover rate and easy to damage. The steel form has long service life, but heavy weight and high cost. The glass fiber reinforced plastic shell 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 dense rib roof beam is with turnover mould shell, this turnover mould shell adopts combined material to make, not only effectively the cost is reduced, and obviously for the mould shell that the polypropylene is single to be made, its turnover number of times increases, and life extension, the technical scheme of adoption is: the utility model provides a dense rib roof beam is with turnover 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 formwork also comprises a frame arranged at the bottom of the peripheral side wall, and the frame and the formwork body are formed by one-time casting molding of a mold, cooling and demoulding.
The frame is made of a metal material in consideration of the convenience of processing and the need for cost saving.
In view of the convenience of the formwork installation, the framework is provided with a vertical extending edge, and the vertical extending edge is provided with a through hole connected with the rib beam formwork. Through this perforating hole by bolted connection spare with the mould shell be connected to the rib beam template on, compare in the steel nail, this connecting piece has better bearing capacity, and the effect of dismouting use is better repeatedly simultaneously.
In order to strengthen the connection firmness, the frame further comprises a support arm which wraps the bottom end of the side wall and extends upwards.
In order to further increase the connection firmness, the support arm extending upwards comprises an upper support arm I and an upper support arm II which are oppositely arranged and have different lengths. The purpose of the unequal lengths of the upper supporting arms is to arrange the two supporting arms in a staggered manner so as to prevent the side walls from being obviously thinned.
In order to further increase the connection firmness, a transverse bulge extending towards the side wall direction is arranged in the support arm; and a support arm transverse groove is formed in the support arm.
In consideration of material cost and process maturity, the formwork is formed by pouring hot-melt plastic material into an aluminum framework through a die, cooling and demoulding.
In order to realize the purpose of smooth form removal, the included angle between the outer contour line 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 formwork is formed by compounding two materials, so that the cost is saved, the turnover frequency of the formwork is increased, and the dead weight of the formwork is reduced; the formwork is connected to the rib beam formwork through bolts, so that the formwork can be quickly disassembled; the mold shell has the advantages of low investment, long service life and high operation efficiency.
