Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, a concrete strip formwork for a road tooth backrest comprises a plurality of interconnected mold body units and a connecting formwork 3 for fixing two adjacent mold body units.

Wherein, every die body unit all includes horizontal template 1 and two side form boards 2 of perpendicular connection in horizontal template 1 both sides respectively, and side form board 2 is fixed with T shape fixture block 23 along vertical direction towards the tip of horizontal template 1, and horizontal template 1 both ends are seted up and are pegged graft T shape draw-in groove 11 of complex with T shape fixture block 23. The transverse formwork 1 and the side formworks 2 at two ends of the transverse formwork are matched with each other through the T-shaped clamping blocks 23 and the T-shaped clamping grooves 11 in an inserted mode, the transverse formwork 1 and the side formworks 2 are spliced into a formwork unit conveniently, and the transverse formwork 1 and the side formworks 2 after being spliced form an open die cavity together. The mold cavity is used for pouring concrete to finish the construction of the curb backrest.

Referring to fig. 3 and 4, L-shaped slots 12 are horizontally formed in both sides of the transverse formwork 1, and the L-shaped slots 12 are located in the middle slot walls of the T-shaped slots 12 and are communicated with each other.

The opposite side surfaces of two adjacent side templates 2 between two adjacent die body units are respectively provided with a strip clamping block 21 and a strip clamping groove 22 which are mutually inserted and matched. Rectangular fixture block 21 and the mutual joint cooperation of rectangular draw-in groove 22 to the location when convenient mutual concatenation between a plurality of die body units, and then convenience of person of facilitating the use when splicing die body unit, and then increased the efficiency of construction.

Referring to fig. 4 and 7, a bottom groove 24 is formed in the side formwork 2 in the vertical direction, the bottom groove 24 penetrates through the upper end face and the lower end face of the side formwork 2, the bottom end of the bottom groove 24, which is close to the transverse formwork 1, is arranged as an opening, an ejector rod 25 is fixedly connected to the inner wall of the bottom groove 24 in the vertical direction, the bottom end of the ejector rod 25 is arranged in a wedge shape, the top end of the ejector rod 25 is communicated with the outside of the upper portion of the side formwork 2, and a pull ring 26 used for pulling the side formwork 2 is fixed to the upper end. Pulling the pull ring 26 upwards can then pull the sideform 2 to move the sideform 2 away from the cross-form 1 to facilitate removal of the sideform 2 from the cross-form 1.

And in order to conveniently dismantle the adjacent side templates of two adjacent die body units, and assemble two adjacent die body units into a bigger new die body unit of size, as shown in fig. 5 and 6, the size of 3 width directions of connecting template equals the size of 2 thickness directions of side template, and 3 both sides of connecting template are all fixed with the L-shaped fixture block 23 that sets up along the horizontal direction, L-shaped fixture block 23 and L-shaped draw-in groove 12 are the mutual joint cooperation, when using connecting template 3 to couple together the horizontal template 1 in two adjacent die body units, the L-shaped fixture block 23 of both sides correspondingly the joint in the L-shaped draw-in groove 12 in the horizontal template 1 that it connects.

As shown in fig. 5 and 8, two push rods 32 are fixed on one side of the connecting template 3, one end of each push rod 32 is arranged in a wedge shape, and the push rods 32 are respectively matched with the bottom grooves 24 of the two side templates 2 in an inserting manner. When the two die body units are connected by using the connecting template 3, the push rod 32 is inserted into the bottom groove 24 at the moment, the connecting template 3 is continuously pushed, and the push rod 32 continuously slides in the bottom groove 24 until the bottom end part of the ejector rod 25 is contacted; continuing to push the connecting formwork 3, the ram 25 will be lifted under the squeezing action of the push rod 32, whereupon the pull ring 26 moves away from the sideform 2, whereupon the staff can use the tool to take the sideform 2 up. And at the moment, the connection of the plurality of die body units is completed, so that the construction is convenient to carry out. When the formwork needs to be completely taken out after construction is completed, the formwork is disassembled in the direction far away from the connecting formwork 3, and the construction efficiency is improved.

Specifically, in consideration of the fact that the push rod 32 leaves a preset hole after the cast concrete is formed in actual construction, the size of the push rod 32 can be adjusted to be smaller properly, and the push rod 25 only needs to be jacked upwards to enable the side formwork to be loose, so that an operator can lift the side formwork directly. Meanwhile, after all the templates are installed, the back surfaces of the templates need to be fixed, and heavy object support or steel bars can be adopted for abutting, so that the templates of all the sections can be kept vertical when concrete is poured, and displacement deviation is reduced.

The utility model discloses a theory of operation and beneficial effect:

the utility model discloses a mutually supporting of T shape fixture block 23 and T shape draw-in groove 12, mutually supporting of L shape fixture block 23 and L shape draw-in groove 12, the cooperation of ejector pin 25 through push rod 32 makes pull ring 26 can carry out convenient dismantlement work to curb plate 2, can dismantle side form 2 fast, the degree of difficulty of dismantling and assembling curb back concrete strip template has been reduced, facilitate the construction operation of using curb back concrete strip template, the efficiency of construction operation and then shortened the time limit for a project of road surface construction.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
