Abstract
The utility model relates to a plastic round hole plate which is a mould plate in the shape of a rectangular plate and is mainly used for casting concrete during building construction. A plurality of round holes are arranged in the plate and are lengthwise communicated, grid-shaped steel bards processed through the prestressing treatment are buried in parallel on the periphery of round holes in advance, and both side surfaces of the plate are respectively provided with grooves and convex ribs. Thus, same plates can be spliced conveniently and the utility model has convenient installation and disassembly and can reduce the consumption of limited wood.
Description
The utility model belongs to building construction technology, particularly the template used of concrete pouring.
The common technology of concrete pourings such as flooring, aspect, wallboard, crossbeam is in building operations, adopts swage plate or wooden form member to surround die cavity, is poured into and removes template after concrete is waited to solidify, and this template is reusable.The swage plate has the high advantage of intensity, but cost height, Heavy Weight, installs, carrying is all inconvenient, and operating efficiency reduces, and construction cost improves; Wooden form weight is lighter relatively, but intensity is relatively low, and can produce the phenomenon that expands, contracts after water contacts, its surface is the bonding concrete easily, influences quality, the especially government strict control forest harvesting of casting area, wooden valency is raise, all cause the increase of construction cost, and install also inconvenient.
The purpose of this utility model is the circular hole slab member that a kind of high strength, low weight, low cost, use and convenient transportation are provided for building trade, reduces the consumption of building trade to timber.
The utility model adopts plastics to be extruded into square template piece, and the design main points are to be shaped on the circular hole that several vertically connect in the plate, are embedded with the reinforcing bar of process autofrettage in circular.
In the two sides of this rectangular panel blocks, be shaped on longitudinal fluting and vertical raised line respectively, can make the identical plate of polylith make things convenient for amalgamation successively.
Pre-buried reinforcing bar can be that vertical grizzly bar is arranged, the grid that also can intersect is in length and breadth arranged.
The plastic cement circular hole slab that utilizes the utility model to make had both kept the intensity index of original product, had the following advantages again:
1, in light weight, use, convenient transportation, cost is low;
2, any surface finish is difficult for bonding cement;
3, the recyclable utilization of material has reduced consuming excessively limited timber resources;
4, except as the concrete casting injection molded plate, also can be used as constructional materials and use, as indoor partition wall, floor etc., the also base plate of alternative existing automobile bodies;
In the accompanying drawing, Fig. 1 is a front view of the present utility model, and Fig. 2 is the A-A sectional view of Fig. 1, and Fig. 3 is Fig. 2 B-B sectional view.
Be described further below in conjunction with accompanying drawing and manufacturing process.
The design size that at first connects rectangular panel blocks 1 is made mould.The square molded dimension of present embodiment is 300 * 3 * 50 (cm).Each plate 1 centre is left 9 and is connected circular holes 5, and the reinforcing bar 4 parallel longitudinal direction grizzly bar shapes of passing through autofrettage are arranged in the die cavity, and it is distributed in around each circular hole 5.The PVC plastic resin that will insert an amount of age resistor is then clamp-oned in the die cavity and is solidified into plate 1.In the two sides of every plate 1, be shaped on longitudinal fluting 3 and vertical raised line 2 respectively, make per two plates form concavo-convex connecting, it is very convenient to install, dismantle.The utility model sample after tested, the performance GB8814-88 requirement that is up to state standards.
Claims (3)
1, a kind of prestressing force plastic cement circular hole slab, rectangular plate (1) is characterized in that being shaped in the plate (1) circular hole (5) that several vertically connect, and is embedded with the reinforcing bar (4) through autofrettage around circular hole (5).
2, plastic cement circular hole slab according to claim 1 is characterized in that the side of plate (1) is shaped on longitudinal fluting (3) and vertical raised line (2) respectively.
3, plastic cement circular hole slab according to claim 1 and 2 is characterized in that pre-buried reinforcing bar (4) can be that vertical grizzly bar is arranged, the grid that also can intersect is in length and breadth arranged.
