Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of pouring formwork of high thin-walled wallboard reentrant corner part. BACKGROUND

[0002] With the gradually aggravating water pollution caused by traditional printing and dyeing or chemical industry, the planning and construction of sewage treatment plants are paid more and more attention by construction units. As a key construction category of municipal engineering, the construction technology of high thin-walled pool body structure of sewage treatment plants has always been a construction difficulty of municipal engineering. The functions of various treatment pool bodies in sewage treatment plants are different, and the internal structure is usually separated by partition walls. In addition, the construction area occupied by a single pool body is also limited, resulting in that the partition wall is usually high and thin-walled, and the wall of the entire pool is characterized by thin wall thickness, high height and dense reinforcement.

[0003] During the setting of the wall formwork, the site environment is often complex: cutting the formwork often produces formwork debris; welding the reinforcement also produces welding slag; the personal equipment of workers and the materials used may produce debris and garbage, and these small sundries may fall into the reinforcement formwork intentionally or unintentionally and deposit at the bottom of the formwork finished product. Due to the environmental characteristics of thin wall thickness, high height and dense reinforcement of the pool wall, it is very difficult to completely clean up all the garbage: the dust collector conduit cannot be extended to the bottom for cleaning due to the obstruction of the wall reinforcement, and the air force of the air blower is not enough to blow up the garbage at the root of the high wall. The above status leads to the accumulation of a large amount of debris at the wall position during the pouring of the wall concrete, which finally causes the root rot of the wall and the problem of wall seepage in the later period, which adversely affects the economy and efficiency of the operation of the sewage treatment plant. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at overcoming the defects of the prior art and providing a pouring formwork for the reentrant corner part of a high thin-walled wallboard, which solves the problem of incomplete cleaning of the garbage at the bottom of the formwork after the setting of the wallboard formwork is completed and helps to improve the pouring quality in the later period.

[0005] The technical scheme for achieving the utility model is as follows: a pouring formwork for the reentrant corner part of a high thin-walled wallboard, comprising a formwork body and a discharging device.

[0006] The formwork body comprises two pieces of plywood that are spliced into an L-shaped plane, and a rectangular notch is formed at the root of each of the two pieces of plywood, and the notches on the two pieces of plywood constitute a discharge port.

[0007] The discharging device comprises two side guide rails, a middle guide rail, a discharge baffle and a support frame; wherein,

[0008] The side guide rail and the middle guide rail are at the same height and at least twice the height of the discharge port. The two side guide rails are installed on the back of the two plywood boards and are located on the two sides of the discharge port respectively.

[0009] The central guide rail is installed at the corner where the two plywood boards are joined.

[0010] The discharge baffle is formed by splicing two rectangular iron plates into an L shape. The height of the two iron plates is adapted to the height of the discharge port, and the length of the two iron plates is adapted to the length of the notch on the bakelite board. Side sliding strips adapted to the side guide rails are fixed on both sides of the two iron plates, and a middle sliding strip adapted to the middle guide rail is fixed at the splicing corner of the two iron plates, so that the discharge baffle can be slidably embedded in the two side guide rails and the middle guide rail.

[0011] The support frame has an isosceles right triangle shape and includes two inner support rods and one outer support rod; the two inner support rods are spliced ​​into an L-shape and fixed to the back of the two iron plates of the discharge baffle, and the splicing angle of the two inner support rods is located at the splicing angle of the two iron plates; the outer support rod is connected between the outer ends of the two inner support rods.

[0012] The casting template for the inner corner of the aforementioned tall thin-walled wall panel includes several horizontal wooden blocks, several pairs of vertical steel pipes, and several sets of tie bolts on the back of each plywood board.

[0013] In the aforementioned casting template for the inner corner of the tall, thin-walled wall panel, the bottom surface of the discharge baffle of the discharge device is an inclined surface.

[0014] In the aforementioned casting template for the inner corner of the tall thin-walled wall panel, the two ends of the two inner support rods of the discharge device support frame are each fixed to the back of the two iron plates one-to-one by iron plates.

[0015] The casting template for the inner corner of the aforementioned tall thin-walled wall panel includes a discharge device that further comprises two handles that are fixed one-to-one on the back of the two iron plates and located one-to-one above the two inner support rods.

[0016] The casting template for the internal corner of the tall, thin-walled wall panel of this utility model has the following characteristics:

[0017] 1) The structure is simple, the assembly is not difficult, and the design and manufacturing cost is low; in addition, the support rod in the discharge device can effectively offset the lateral pressure generated by the accumulation of concrete at the bottom of the wall during the actual pouring process, effectively improving the overall durability of the formwork.

[0018] 2) The template of this utility model can be installed at the inside corner of the exterior wall, the inside corner of the exterior wall and the interior wall, and the inside corner of the interior wall. It has a wide range of applicable environments, greatly reduces the risk of leakage of the exterior wall and improves the overall cleanliness of the wall.

[0019] 3) The discharge baffle in this utility model can be raised and lowered in time after the inside of the template is cleaned, so as to completely protect the finished steel bars inside; at the same time, the up and down movement will not cause inconvenience to the later demolding of the wall, and also maintain the flatness of the concrete wall of the corresponding pouring part.

[0020] 4) The template of this utility model can be used in combination with ordinary templates and is suitable for various wall types and tall thin-walled walls under various construction conditions;

[0021] 5) The template of this utility model is reinforced with paired steel pipes and double tie bolts, which greatly ensures the firmness and stability of the template. At the same time, the discharge baffle is made of galvanized iron plate, which can improve the overall strength of the template. Attached Figure Description
