Technical Field
The utility model belongs to the field of construction tools for constructional engineering, and particularly relates to a simple device for manufacturing a concrete inner stay on site.
Background
In building construction, shear walls and deeper beams need to be reinforced. In the reinforcing process, the relative positions of the shear wall and the templates at the two sides of the deeper beam are difficult to fix. The initial adoption is cut off the reinforcing bar waste material and is regarded as the inner stay to this fixed both sides template's relative position improves to adopting prefabricated place producer to produce in advance the concrete prefabricated inner stay to fix afterwards, still has following not enough: (1) cement used in a prefabrication factory is usually different from concrete used in a construction site, and in the process of connecting a concrete prefabrication inner stay with a shear wall or a beam, the concrete is not perfectly adhered to each other, so that the construction quality is adversely affected; (2) the prefabricated inner stay has more dimension and larger dead weight, is difficult to transport and store, and increases the production cost; (3) the prefabricated inner stay has low general strength, small thickness and large loss in the transportation process; (4) the number of prefabricated inner stay manufacturers is limited, the distribution is uneven, especially, the number of manufacturers is less at remote and later places, and a large number of prefabricated inner stays need to be transported for a long distance, so that the construction cost is increased; (5) the prefabrication production period is long, influences the construction progress.
The existing concrete internal stay has high reverse die price, the reverse die manufacturing concrete protection layer internal stay has slow internal stay speed, coarse forming quality and poor internal stay using effect.
The utility model patent with publication number of CN106994740A discloses a method for making internal stay of a fine stone concrete wall column by site, which comprises the steps of firstly adopting a stainless steel square tube to manufacture a die, wherein the die comprises a rectangular outer frame, a group of mutually parallel parting strips uniformly distributed in the frame, and a pair of handles symmetrically arranged on two sides of the outer frame; then manufacturing an inner stay framework and a bottom die: manufacturing a flat bottom die by adopting a laminate or engineering plastic or steel plate; placing the bottom die on the bottom die, brushing a release agent on the surface of the bottom die, and placing the die on the bottom die; then pouring and tamping the first layer of fine stone concrete into the mould; uniformly distributing a group of inner stay frameworks which are parallel to each other on the first layer of fine stone concrete; casting and tamping a second layer of fine stone concrete on the first layer of fine stone concrete, namely the inner stay framework; and standing until the fine stone concrete is solidified and formed, lifting the handle, and separating the die from the solidified and formed fine stone concrete to obtain the wall column inner stay material. The parting bead in the die device provided by the utility model is easy to deviate by adopting a welding mode, so that the manufactured internal stay is uneven, and the compression bar is not arranged above the internal stay, so that the manufactured internal stay is not compact and has insufficient strength, the quality is rough, and the use effect of the internal stay is poor.
Disclosure of Invention

Detailed Description
The technical scheme of the utility model is described in detail below with reference to the accompanying drawings and the specific embodiments.
Fig. 1 is a schematic structural view of a simple device capable of manufacturing a concrete inner stay at a construction site, and fig. 2 and 3 are schematic sectional structures of different surfaces, wherein the simple device for manufacturing the concrete inner stay at the site comprises slot battens 1 arranged on two sides, a plurality of inner parting strips 2 are uniformly arranged in the middle of the slot battens 1 at intervals, two groove pressing strips 3 are arranged above the inner parting strips 2, and the groove pressing strips 3 are used for preventing the inner parting strips 2 from shifting and ensuring the thickness of the concrete inner stay.
According to the actual construction needs, the spacing, the length, the width and the like of the inner stays can be set, the inner sides of the slot battens 1 in the embodiment are uniformly provided with grooves with the width of 20mm and the depth of 10mm, and the spacing between every two adjacent grooves is 30mm. The height of the inner parting bead 2 is 40mm, and the thickness is 20mm. The groove pressing bar is 65mm high and 20mm thick. The groove pressing strip is provided with a clamping groove with the width of 20mm and the depth of 25mm corresponding to the inner parting bead.
The field manufacturing process is as follows: the method comprises the steps of (1) centering and sawing a waste wood square of 40 x 80mm to form two wood squares of 40 x 40mm, and arranging grooves with the width of 20mm and the depth of 10mm on the wood squares at the interval of 30mm to serve as two side slot wood squares 1; according to the sectional dimension of the component, a template strip with the height of 40mm and the thickness of 20mm is cut and taken as an inner parting strip 2, a template strip with the height of 65mm and the thickness of 20mm is cut and taken as a groove pressing strip 3, clamping grooves with the width of 20mm and the depth of 25mm are formed in the groove pressing strip 3, and the spacing between adjacent clamping grooves is 30mm.
