Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an apparatus for safely and easily constructing reinforcing bars or steel-framed concrete walls sequentially to a required height 1, and more specifically, a device for constructing reinforcing bars or steel-framed concrete walls in a continuous manner, safely and easily. It concerns an alternating raising device.

An example of implementation of the device of the present invention will be described below based on the drawings.

In FIG. 1, A is the lowest concrete wall constructed in advance on the foundation, and this concrete wall A
The lower part of each support column 1 is removably restrained and erected by an anchor port 2 on the front and rear surfaces of the apparatus.

It is assumed that the supports 1 on the same side are provided at required intervals in the width direction of the concrete wall A.

For example, upper, middle, and lower scaffolds 3 are provided between the outer sides of each column 1 on the same side, and these scaffolds 3 allow reinforcement
Performs work such as pouring concrete and operating formwork.

A steel rod 4 is provided between the upper and lower inner sides of each of the pillars 1, and a hydraulic jack 5 that penetrates and meshes with the steel rod 4 at the center is provided on this 914 shaft 4. is supported by an arm 6 slidably provided on each support column 1. Further, the upper part of the formwork 7 is connected to each hydraulic jack 5 on the same side via the arm 6, At the bottom of this formwork 7, a slim arm 8 is connected to each support l on the same side and is slidably provided at the 11th position.

As shown in FIG. 2, the hydraulic jack 5 has, at the upper and lower portions of the hydraulic jack 5, a pair of concs 5a and 5b in opposite directions that mesh with the steel rod 4, and each pair of concs 5a,
5b'5 has a lever 5C for opening and closing, and the formwork 7
When raising the column 1, push up each lever 5c' to supply pressure oil from the upper port (5d) of the hydraulic geyser 5, and when to raise the column 1, push down each lever 5ck to supply hydraulic oil. Pressure oil is supplied from the lower port 5e of the jack 5.

In FIG. 1, the front and rear formworks 7 are raised, and the lower part of each formwork 7 is removably restrained by anchor bolts 9 at the top of the lowest concrete wall A, and the front and rear formworks 7 are raised. After setting the anchor bolts 9 between the upper parts of the walls, concrete was poured and the second stage concrete wall I3 gold was constructed.

Now, in constructing the eight concrete bodies of the third stage, the restraint by the anchor bolts 9 of the formwork 7 in the front and back directions in Fig. 1 is released, and the formwork is removed from the concrete wall B of the second stage of the culvert. After peeling off the formwork 7, the lower part of the formwork 7 is removed from the upper part of the second stage concrete wall B as shown in FIG. The lower part of the formwork 7 is restrained by the anchor bolts 9 at the upper part of the second stage concrete IJ-to wall body B. After the anchor bolts 9 are set on the upper part of the formwork 7, concrete is poured. Then, construct the third stage concrete wall C.

After curing the constructed 3-tier concrete wall C,
Restriction by anchor bolts 2 between the lower part of the pillar 1 and the lowest concrete wall A on the front and rear sides "k jQ'
After that, in the return stroke of the hydraulic jack 5, the lower part of the support column 1 is used as a reaction force for the 7 formworks, and the upper part of the concrete wall A of the lowest stage and the concrete wall of the second stage as shown in FIG. The lower part of the pillar 1 is restrained by the anchor bolt 2 between the upper part of the lowest concrete wall A and the lower part of the second concrete wall B, and then the same as above. Then, the formwork 7 is raised and the fourth stage concrete IJ) wall is constructed.

In addition, the support column 1 or the formwork 7 may be raised at the same time as the front 11411, or on each side ((it is only necessary to raise it by 7t).

As described above, in the device of the present invention, a steel rod is provided between the upper and lower sides of a support with a scaffold, a hydraulic jack is penetrated and engaged around this steel rod, a formwork is connected to the hydraulic jack, and the formwork is attached to an existing concrete wall. When the lower part of the column is not restrained by the existing concrete or wall, the formwork can be moved to the required position by raising the hydraulic jack relative to the steel rod during the hydraulic jack's working stroke. The lower part of the raised formwork is restrained to the existing concrete wall, the lower part of the column is released from the existing concrete wall, and the hydraulic jack returns to the formwork. The column can be raised as a reaction force, and the load of the hydraulic jack acts on the steel rod in the tensile direction, so even if relatively thin steel rods and small hydraulic jacks are used, the formwork It is possible to safely and easily raise the pillars and scaffolding columns alternately, and it is possible to safely and easily construct reinforcing bars or steel-framed concrete walls one after another to a required height.

Claims (1)

[Claims] On the front and rear surfaces of the lowest conocrete wall that had been pre-constructed on the foundation, a scaffolding column was originally installed with its lower part removably restrained, and a column was installed between the top and bottom of this column. a hydraulic jack that is penetratingly meshed with the steel rod as a center and is slidably supported on the column via an arm; the upper portion is connected via the arm and slides on the column; The lower part is connected to the upper part of the front and rear surfaces of the concrete wall through an arm that is removably provided, and it originally consisted of a formwork whose lower part was removably restrained to the upper part of the front and rear surfaces of the concrete wall. When the formwork is not restrained by the existing concrete wall and the lower part of the support is restrained by the existing concrete wall, during the working process of the hydraulic jack, the hydraulic jack 'k1. By raising it relative to A bar,
The formwork is raised to the required height, the lower part of the raised formwork is removably restrained to the existing concrete wall, and the restraint of the lower part of the column to the existing concrete wall is released, and the hydraulic jack is moved back. Continuous concrete wall construction equipment that uses the formwork as a reaction force to raise the column during the process, and removably restrains the lower part of the column to the existing conocrete wall one step above.
