Abstract

The invention relates to a fabricating method for cement-table panel of table tennis table, belonging to the sport instrument field. The table tennis table made of cement-table panel is suitable for mass physical exercise, especially high-school, elementary-school campus. The invention mainly comprises following technologies. Firstly, frame is welded by angle steel and reinforcing steel bars with the shape like the Chinese character 'jin' are fixed in the frame. Then, a bracket constituted by four legs and pulling bar is used. Rubber pads are fixed on tops of legs and a flat glass is set on rubber pads. The frame is set on the flat glass and soft pad is set between the frame and the flat glass. Upper clamping frame made by four angle steels is set on the frame and connecting plate with hole is welded on the upper clamping frame. A lower clamping frame is set on the bottom of flat glass. There is an extruding end on the lower clamping frame and on the extruding end there is a hole. The hole on the connecting plate on the upper clamping frame is connected with the hole on the extruding end of lower clamping frame by bolt. Upper and lower clamping frames are tightened by nut and gasket on the bolt. Cement is cast in the frame again. The invention is provided with smooth flat and beautiful table panel and can adapt the exercise demand of table tennis lover. At the same time the invention can be placed in air and can satisfy student demand in primary and elementary schools.

Description

The preparation method of cement table top board of table tennis table

One, technical field:

The invention belongs to the sports apparatus field.

Two, background technology:

Present table tennis table is generally all made by timber, and this billiard table water resistance is relatively poor, and this billiard table is adapted at indoor use, is not suitable for outdoor application.Also having a kind of billiard table is the deck plate of being made billiard table by cement plate, and the leg of billiard table is propped deck plate with brick one-tenth or with the support of iron, and this billiard table arrives in that middle and primary schools' back warp is common, is the good place to go that students is played table tennis.Wooden table tennis table is not suitable for the use of vast middle and primary schools, only is fit to specialty table tennis sportsman, and economic condition is good, has between special prefabricated house, and perhaps regulation game is used, and is not suitable for mass movement widely.The billiard table of present cement plate table top is of rude workmanship, the table top out-of-flatness, and service life is short, and maintenance is inconvenient, uses the purpose that does not satisfy the exercise paddler, the raising of the ball game skills that are unfavorable for rattling.According to above-mentioned situation, to improve the preparation method of the cement plate table top of existing table tennis table.

Three, summary of the invention:

Purpose of the present invention is a kind of both attractive in appearance for making, generous again exactly, can be the preparation method of the cement table top board of table tennis table of tempering the paddler again.

The technical scheme that technical solution problem of the present invention is adopted is: at first be welded into frame with angle steel, fixing groined type reinforcing bar in the frame, again with a support of forming by four legs and pull bar, the top of leg is fixed with rubber cushion, put one flat plate glass on the rubber cushion, put frame on the plate glass, be placed with cushion between frame and the plate glass, be placed with the last clamp frame made from four angle steel above the frame, be welded with connecting plate with holes on the last clamp frame, put a following clamp frame on the bottom surface of plate glass, done external part on the following clamp frame, done porosely on the external part, the hole on the hole of the connecting plate on the last clamp frame and the following clamp frame external part couples together with bolt, use nuts and washers fastening clamp frame, casting cement in frame more up and down on the bolt.

Beneficial effect of the present invention is: deck plate is smooth, smooth, attractive in appearance, can adapt to the table tennis fan and temper needs, can place in the open simultaneously, can satisfy student's needs of middle and primary schools.

Four, description of drawings:

Fig. 1 is a front elevational schematic of the present invention, and Fig. 2 is the schematic top plan view of Fig. 1, and Fig. 3 is the A-A sectional drawing of Fig. 1, and Fig. 4 is the sectional schematic diagram after the cement deck plate is made, and Fig. 5 is the floor map of clamp frame (10).

Five, the specific embodiment:

Describe preparation method of the present invention and product situation in detail in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5.The cement deck plate is the frame of being made by angle steel (1), does muscles and bones with reinforcing bar (2) in the frame, at frame (1) casting cement (3), has just become the cement deck plate of table tennis table after waiting to the cement solidifies.The cement deck plate will be done smoothly, and a smooth cover way and the instrument wanted finished.At first be welded into frame (1) with angle steel, fixing groined type reinforcing bar (2) in the frame, again with a support that has four legs (14) and pull bar (15) to form, the top of leg is fixed with rubber cushion (16), put one flat plate glass (11) on the rubber cushion, put frame (1) on the plate glass, be placed with cushion (17) between frame and the plate glass, be placed with the last clamp frame (4) that four angle steel are made above the frame, be welded with connecting plate with holes (5) on the last clamp frame, put a following clamp frame (10) on the bottom surface of plate glass (11), done external part (6) on the following clamp frame, done porosely on the external part, the hole on the hole on the connecting plate (5) on the last clamp frame (4) and following clamp frame (10) external part couples together with bolt (7), use the fastening clamp frame (4) up and down of nut (9) and packing ring (8) on the bolt, (10), again at frame (1) lining casting cement (3).This way is utilized smooth, the smooth face of plate glass (11) exactly, the face of making cement deck plate, the table top of table tennis table just, in order to utilize the face of plate glass, two clamp frame (4), (10) are clipped in plate glass on the narrow limit of frame (1) lower edge about just having done, and make the water-tight mud of intersection of frame (1) and plate glass (11).For water-tight mud, on four limits of last clamp frame (4) and following clamp frame (10),, the snap ring (12) of screw rod (13) is housed in the screw with screw is arranged, clamp clamp frame (4), (10) up and down.Here it is in order to reduce the slit, perhaps do not stay the slit set.Table tennis table all is by two billiard tables, synthetic table tennis table.Table tennis table of the present invention also is made up of two cement deck plates, and the cement deck plate is installed in by shaped steel and makes, and uses on dismountable supporting leg, so this table tennis table can be placed in the open, is not made of salt.When cement is solidified to after date in frame (1) lining, unclamp all securing members, up and down clamp frame (4), (10) to be pulled down, snap ring (12) is pulled down, and the cement deck plate has just been carried out.
