Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is designed to be installed on the edge of elevated concrete deck slabs for railways and roads. The present invention relates to a wall balustrade molding device for molding a wall balustrade to be installed.

0002

[Conventional technology]

Conventionally, when forming a wall balustrade, vertical reinforcements for the wall balustrade were added when forming the concrete slab. Let it protrude from the edge of the floor slab, bend it vertically, and attach the horizontal striations. At the same time, construct inner and outer concrete forms on the outside and pour concrete. This allows the wall railing to be molded into one piece with the floor slab.

0003 The equipment for forming this wall railing is a traveling rack with a cantilevered hanging scaffold support. Installing a horizontal scaffold under the edge of the floor slab using a platform and supporting the suspended scaffolding support material; Work such as reinforcing bar work and formwork work was being carried out on the scaffolding.

0004

[Problem that the idea aims to solve]

The above-mentioned conventional wall balustrade forming equipment includes frames, formwork, and components for suspended scaffolding. The equipment for concrete pouring is all constructed separately, especially the pedestal. was only for supporting the suspended scaffolding, so the assembly and removal of the formwork was not possible. , the formwork must be supported by another lifting means such as a crane, which reduces work efficiency. Not only is it bad, but it also limits the weight of the formwork, so it cannot be made very long. There was a problem that the length of concrete pouring at one time was short.

[0005] In view of these conventional problems, the present invention has been developed to solve problems such as assembling, demolding, and moving formwork. The work is efficient and safe, and the length of one molding process is significantly longer than before. The purpose of this invention is to provide a wall balustrade molding device that can be used to form a wall balustrade.

[0006]

[Means to achieve the task] The features of this invention to solve the above-mentioned conventional problems and achieve the intended purpose are: , a piece that is movable on the elevated concrete slab and is suspended below the edge of the slab. a trolley having a suspended scaffold support; Horizontal scaffolding inserted under the edge and wall parapet molding integrally molded on the edge of the floor slab. In a wall balustrade forming device comprising a concrete formwork for Two carts are provided, and both carts are detachably connected via a connecting member, and the cart is connected to the controller. Both ends of the cleat formwork are supported via hanging materials and hydraulic cylinders for opening and closing the formwork. At the same time, the horizontal scaffolding supported by both carts can be separated using a connecting scaffolding material. There is a wall balustrade molding device that is characterized by continuous performance.

[0007]

[Effect]

The device of this invention can be used normally by separating the two carts and removing the formwork from the cart. It can be used as a mobile suspended scaffold for processing the edges of floor slabs, arranging reinforcement for wall balustrades, and even after forming wall balustrades. It can be used as a scaffold for surface finishing work, etc.

[0008] Also, connect both carts and support both ends of the formwork via hydraulic cylinders and hanging materials. The formwork is then moved to the desired wall balustrade forming position.

[0009] The hydraulic cylinders are then activated to assemble the formwork in place and release it into the hopper. Pour the concrete into the formwork. For demolding after molding, the formwork was supported by both carts. Since this is done by operating a hydraulic cylinder under the condition, other lifting means such as a crane is required. do not have.

【Example】

Next, embodiments of the present invention will be described with reference to the drawings.

[0011] In the figure, 1 is the elevated concrete slab, and 2A and 2B are placed on the slab 1. It is a self-propelled trolley. Both carts are not shown in detail in the diagram, but are powered by hydraulic motors. It is designed to be able to run by driving the wheels. Both trolleys 2A and 2B are their mounts. The parts 3, 3 are connected by a pair of connecting rods 4, 4. These connecting rods 4, 4 , both ends are removably pivotally connected to each frame part 3, 3 by pins 5, 5. There is. Furthermore, a bridge body 6 is spanned over both frames 3, 3, and a hopper movement path 7 is continuously arranged. It is located at

0012 On the pedestal section 3 of one of the trolleys 2A, there is a A rail 8 is installed via gate-shaped supports 9, 9, and a hoist 15 is used to lift the hopper 1. 0 can be lifted up and moved between the top of the hopper movement path 7 from outside one end of the pedestal section 3. It has become.

[0013] Both carts 2A and 2B each have a groove extending outward from the edge of the concrete slab 1. A pair of horizontal beams 11, 11 are protruded in a cantilevered manner. Vertical hanging materials 12, 12 are fixed to the tips and suspended, and horizontally attached to these vertical hanging materials 12, 12. A hanging scaffold 13 in the direction of is supported in a cantilevered manner. In this way, both trolleys 2A, Scaffold 14 is stretched across both suspended scaffolds 13 and 13 suspended from 2B. . As shown in FIGS. 5 and 6, hanging members 20 are installed under the horizontal beams 11 and 11 of both carts. A formwork 21 for a wall balustrade is suspended. This formwork 21 has steel inner and outer surfaces. Consists of templates 22, 23 and end templates (not shown), both inner and outer templates. 22 and 23 are pivotally connected to each other via a top metal fitting 24 so as to be freely openable and closable, and the whole is attached to the hanging member 20. Hold it at a predetermined height with the Hydraulic cylinders 25a and 25b are interposed between the stand 2 and the vertical hanging member 12, and this The inner and outer mold plates 22 and 23 are opened and closed by both hydraulic cylinders.

[0014] Note that the formwork 21 has the lower edge of the outer template 23 attached to the concrete floor slab as shown in FIG. It is supported by a stopper 26 fixed to the bottom of the edge of 1, and both the inner and outer mold plates 22 , 23 and are connected via bolts 27 for assembly.

[0015] When using the device configured in this way, both carts should be With 2A and 2B connected to each other, the formwork 21 is hung with the hanging material 20, and both the formwork plates 22, Both carts are moved to predetermined positions with 23 opened. After that, concrete A stopper 26 is fixed to the lower surface of the edge of the floor slab 1, and each hydraulic cylinder 25a, 25b to assemble the formwork 21 in a predetermined position.

[0016] Next, the concrete is placed in the hopper 10 and lifted up using the hoist 15. The concrete is transported onto the hopper moving path 7, moved on the moving path 7, and placed in the formwork 21. Pour the REIT.

[0017] After pouring concrete in this way, disconnect the front trolley 2A. In both cases, remove the hanging material 20 and hydraulic cylinders 25a and 25b from the trolley 2A side and remove the mold. With the frame 21 separated, only the trolley 2A is moved forward and its suspended scaffolding is used. Then perform preliminary work such as arranging reinforcement at the next concrete placement position and fixing the stopper 26. . Also, if necessary, the rear truck 2B is also separated from the formwork 21 and concrete is placed first. Finishing work will be carried out on the wall parapets that have been poured.

[0018] When demolding the formwork 21, both carts 2A and 2B are connected again, and the hanging material 20 and Demoulding is performed by connecting and operating the hydraulic cylinders 25a and 25b. and move it to the next concrete placement position.

[0019]

[Effect of the idea]

As mentioned above, the wall balustrade forming device of the present invention uses two trolleys, each with a In addition to supporting the scaffolding, both ends of the formwork are supported by both carts, and the hydraulic system is By using a linder to open and close the formwork, it is possible to create a formwork with a large span. It is possible to work with good operability even when using a I can do it.

[0020] Additionally, since both trolleys can be moved separately from the other parts, It can be used as a place for work incidental to concrete pouring, and it significantly improves work efficiency. This can be greatly improved.
