Description

Drainage ditch pouring template fixing device

Technical Field

The utility model belongs to template fixing device is pour in escape canal.

Background

The concrete drainage ditch of the traditional central separation zone is U-shaped, after a bottom plate is poured, ditch walls on two sides are poured simultaneously, four ditch wall templates are fixed, generally, battens stretch across and are erected above the templates and fixed by iron nails, and two sides of the battens are connected to concrete bottom reinforcing steel bars to be poured by iron wires to be fixed. By adopting a traditional method, in order to strengthen the supporting force of the template, an iron nail with the diameter of more than 5mm is generally used, the fixed battens of the template are difficult to assemble and disassemble, are easy to damage, and have low recycling coefficient. Because the escape canal when carrying out concrete placement, the bearing capacity of stuff support is not enough, leads to the template below can strut because of the power of empting of concrete, and leads to the template skew, when demolising the template simultaneously, need remove the iron nail with the help of the instrument sled, leads to concrete surface and edges and corners that pour to be impaired because of the form removal easily like this.

Disclosure of Invention

The utility model aims to overcome the damaged defect that current central authorities 'separate zone concrete escape canal leads to because of the form removal in the construction process of production, provide an easy operation, quick, can improve the efficiency of construction, guarantee construction precision's escape canal and pour template fixing device.

The utility model discloses the technical scheme who adopts is a template fixing device is pour in escape canal, and its main points lie in, the tight frame of clamp that comprises the fixed 4 vertically fixed supporting arms in a horizontal arm below in it, and the interval between first fixed supporting arm and the adjacent fixed supporting arm of second equals escape canal wall width and both sides template thickness sum, and the interval between third fixed supporting arm and the adjacent fixed supporting arm of fourth equals another ditch wall width of escape canal and both sides template thickness sum.

The cross arm and the supporting arm are made of angle steel. The clamping frames can be formed by welding or fixing parts.

The clamping device is also provided with a longitudinal fixing rod which is fixed between the two clamping frames. Make the clamping frame all have the reinforcing action to whole template through the longitudinal fixing pole between two clamping frames, can prevent effectively that the template below from not being strutted when empting the concrete, guarantee construction quality.

There are 4 longitudinal fixing rods fixed to the bottom of the fixing support arms. Because the bottom end of the fixed supporting arm is stressed by large concrete pressure, the longitudinal fixing rod is fixed at the lower end of the fixed supporting arm, and the effect is optimal.

There are 8 longitudinal fixing rods fixed to the bottom and upper ends of the fixing support arms.

The utility model can be recycled, the template can be ensured not to translate through the plane side of every two fixed supporting arms clinging to the template, the template positioning is ensured to the maximum extent, secondary fixing is not needed, and the installation precision is improved; simultaneously, when demolising the template, need not the instrument and prize and remove, as long as up lift the fixed bolster, can remove the fixed to the template, easy operation has guaranteed the integrality of ditch wall, sled iron nail when also having avoided demolising leads to the damaged defect of concrete, improved the efficiency of artifical demolising greatly, make the clamping frame all have the additional work to whole template through the longitudinal fixing pole between two clamping frames simultaneously, can prevent effectively that the template below from not being strutted when empting the concrete, guarantee construction quality.

Detailed description of the preferred embodiments

The present invention will now be described in detail with reference to the drawings, which illustrate examples that will enable those skilled in the art to more fully understand the invention, but which are not intended to limit the invention in any way

Example 1, as shown in fig. 1 and 2, a gutter-casting formwork fixing apparatus is provided in which a clamp frame consisting of 4 vertical fixing support arms 1 is fixed below a cross arm 2, the distance between a first fixing support arm 11 and an adjacent second fixing support arm 12 is equal to the sum of the width of a gutter wall and the thickness of formwork on both sides, and the distance between a third fixing support arm 13 and an adjacent fourth fixing support arm 14 is equal to the sum of the width of the other gutter wall of a gutter and the thickness of formwork on both sides. The cross arm and the supporting arm are made of angle steel. The clamping frames can be formed by welding or fixing parts. When the cast-in-place formwork is used, after the cast-in-place formwork is accurately positioned, the clamping frames are inserted into the outer side of the formwork at equal intervals, the fixed supporting arms face downwards, the cross arms are arranged upwards, so that the first fixed supporting arm 11 and the adjacent second fixed supporting arm 12 are tightly attached to one side of the trench wall formwork, and the third fixed supporting arm 13 and the adjacent fourth fixed supporting arm 14 are tightly attached to the other side of the trench wall formwork. When the concrete reaches a certain strength, the cross arm of the middle lattice is held to lift upwards when the formwork is removed.

Embodiment 2, as shown in fig. 3, is an improvement on the basis of embodiment 1, and adds a longitudinal fixing rod, which is fixed between two clamping frames, one surface of which is tightly attached to the formwork, and the adjacent clamping frames are placed in opposite or reverse directions, and because the fixing support arm is made of angle steel, the fixing modes between the longitudinal fixing rod and the fixing support arm are different, the longitudinal fixing rod is divided into two types, namely an a-type longitudinal fixing rod 31 and a B-type longitudinal fixing rod 32, as shown in fig. 4 and 5, wherein the a-type longitudinal fixing rod is a fixing surface which is formed by bending two ends of flat steel at right angles and forms an angle steel back plane with the fixing support arm. The B-shaped longitudinal fixing rod 32 is formed by bending two ends of flat steel into steps at right angles, the step height is not less than the thickness of the angle steel edge, the angle steel edge is thin, the processing difficulty is high, the step height can be properly increased, and the gasket is kept stable during fixed installation. The single clamping frame is continuously fixed into a whole through the longitudinal fixing rod, so that the clamping frame has a reinforcing effect on the whole formwork, the lower part of the formwork is effectively prevented from being propped open when the concrete is poured, and the construction quality is ensured. Generally, there are 4 longitudinal fixing rods fixed to the bottom end of the fixing support arm, and 8 longitudinal fixing rods fixed to the bottom end and the upper end of the fixing support arm, with the fixing mode being welding and alternate with fixing pieces. The rest of the composition which is not described is the same as that of example 1.
