Description

template

The invention relates to a template, in particular to the outer periphery of the template, which can be prevented from colliding and the upper and lower surfaces of the template can be prevented from sucking muddy water and scratching, so that the template has the advantages of light weight, good rigidity and high durability.

According to the conventional template 1 structure, please refer to the first and second figures. The multiple layers of the wood plywood 11 are assembled to form the template 1 (commonly known as the water template), that is, before the general construction industry performs the concrete grouting operation. The construction of the formwork building materials is used. However, it is found that the template 1 has the following shortcomings when constructing the appropriate specification model of the building and pouring the concrete into the completed formwork template 1:

1. Since each template 1 attached to the concrete is made of wood material and the surface is easily adsorbed as muddy water in the strong alkali concrete, after the concrete is dried, the surface of each template 1 is strongly attached to the concrete and is easy to seep, resulting in demoulding. The surface of each template 1 wood fiber is easily peeled off and damaged, so that each template 1 can only be used repeatedly for 5 to 6 times, that is, the surface is rough and unbearable.

2. The formwork 1 removed at the construction site is easy to hit the ground, so that the corners of each template 1 are easily warped by the impact of external force 12 and the dents 14 of the sides 13 are easily damaged and damaged, as shown in Fig. 2, The formed wall surface is prone to unevenness, which makes the template 1 unusable.

In view of the above-mentioned shortcomings, the prior art has the "template improvement" No. 89204472 and the "template improvement addition (1)" in the 89204472A01, as shown in FIG. The periphery 20 of the two templates 2 is provided with a bead 21, and the periphery 20 of the template 2 is pressed by the bead 21 so as to prevent the template 2 from being externally warped or deformed by the impact of external force, and thus the two cases solve the strong protective frame around the template 2, However, the two cases are easily adsorbed as muddy water in the strong alkali concrete when the surface of the template 2 is attached to the concrete, resulting in the same problem that the surface of the template 2 is easily peeled off and damaged.

The above-mentioned disadvantages are caused by the use of the templates 1 and 2, and the prior art has the method of manufacturing a plate surface coating process and a product thereof, as shown in Fig. 4, and the wooden plate 31 of the template 3 is shown in Fig. 4. The upper and lower surfaces are covered with plastic 32 under a high temperature liquid high pressure, and the plastic 32 is coated on the upper and lower surfaces of the wooden board 31 to solve the problem that the surface of the template 1 and 2 will absorb mud water, but the wooden board The plastics 32 of the upper and lower surfaces of the 31 are only slightly infiltrated into the surface layer of the wooden board 31, and in fact, the combined fixing force is still insufficient. Therefore, when the surface of the template 3 is subjected to multiple external impacts, the upper and lower surfaces are The plastic 32 will be detached from the wooden board 31 to form an embossed state, which is unusable.

The invention solves the technical problem of improving the combination of the conventional template on the upper and lower surfaces of the wooden board and the plastic. The invention combines the upper and lower plastic layers on both sides of the wooden board, and the plurality of through holes in the wooden board respectively. The connecting column and the plastic frame combined with the surrounding sides are fully integrated, so that the outer periphery of the template can be prevented from colliding and the muddy water and scratches can be prevented on the upper and lower surfaces of the template, so that the template has both light weight and rigidity. The durability is high and the service life is increased. Therefore, the template of the present invention can be reused at least 40 times and weighs only 18 kilograms, which is convenient for handling and construction.

Therefore, for the purpose of the foregoing invention, the technical solution adopted by the present invention is to provide a template comprising a wooden board having a plurality of through holes. a top and a bottom plastic layer, the upper and lower plastic layers are respectively disposed on the upper and lower surfaces of the wooden board; a plurality of connecting columns, the connecting columns are respectively disposed in the through holes of the wooden board and respectively The upper and lower plastic layers are integrally connected; a plastic frame is disposed on the side of the wooden plate and is integrally connected with the upper and lower plastic layers and the wooden plate, whereby the wooden plate is double-sidedly bonded The plastic frame combined with the lower plastic layer and the surrounding sides can increase the strength of the template.

With the template of the present invention, it can mainly achieve the following effects: The wooden board of the invention may be a wood board or plywood or a splint. Technically, the upper and lower plastic layers on the upper and lower surfaces of the wooden board are respectively disposed in the through holes of the wooden board and are respectively connected to the upper and lower plastic layers. And a plastic frame disposed on the side of the wooden plate and integrally connected with the upper and lower plastic layers and the wooden plate, so that the surface of the template of the invention can be anti-collision, scratch-proof and does not absorb muddy water, and is applicable. The formwork building materials used in the construction of the concrete grouting operation make the grouting more effective, strengthen the formwork structure and increase the service life, and provide excellent usability.

The purpose, technical contents, features and effects achieved by the present invention will become more apparent from the detailed description of the embodiments.

Referring to FIG. 5 and FIGS. 6 and 7, the template 4 of the present invention comprises a wooden board 5 which is provided with a plurality of through holes 51; an upper and lower plastic layers 6, 7 which are upper and lower. The plastic layers 6, 7 are about 1.5 mm thin layer, and the upper and lower plastic layers 6, 7 are respectively disposed on the upper and lower surfaces of the wooden board 5; a plurality of connecting columns 8 are respectively disposed on the connecting columns 8 The through holes 51 of the wooden board 5 are integrally connected to the upper and lower plastic layers 6, 7 respectively, and the through holes 51 are evenly distributed on the wooden board 5 in a preferred embodiment. The connecting posts 8 are uniformly distributed in the through holes 51. The connecting posts 8 are integrally connected to the wooden board 5 and the upper and lower plastic layers 6 and 7 respectively; a plastic frame 9 and the plastic frame 9 is disposed on the side of the wooden board 5 and is integrally coupled with the upper and lower plastic layers 6 and 7 and the wooden board 5 to strengthen the structure of the template 4; further, the plastic frame 9 is used to protect the wooden board 5 With the anti-collision effect, the thickness W of the plastic frame 9 can be greater than the thickness of the wooden board 5.

The wooden board 5 can be a wooden board or a plywood or a splint. The wooden board 5 is structurally rigid and does not deform, and the upper and lower plastic layers 6, 7 disposed on the upper and lower surfaces of the wooden board 5, the connecting posts 8 in the through holes 51, and the wooden board The plastic border 9 on the side of the 5 is made of PP plastic material, so that the weight of the template 4 is only 18 kg, and the plastic material of the upper and lower plastic layers 6, 7 and the connecting posts 8 and the plastic frame 9 are It can be anti-collision, scratch-proof and does not absorb muddy water, and it can be decomposed and has the advantages of environmental protection and low cost. Therefore, the template 4 of the present invention can be reused at least 40 times.

However, it is conceivable that the template 4a of the present invention is entirely made of PP polypropylene, such as As shown in Figure 8, the following shortcomings will occur: 1. The weight of the template 4a plate is 25 kg, which is difficult to handle, affecting the construction efficiency and increasing the construction cost; 2. The unit price is high due to the full PP material and the cost is relatively high 3; template 4a It is structurally soft and easily deformed to cause insufficient rigidity. In use, it is necessary to additionally support a plurality of back struts 41a at the bottom end of the stencil 4a, which is an increase in construction and material cost.

Therefore, in the embodiment of the present invention, the wooden board 5 of the template 4 is provided with upper and lower plastic layers 6 and 7 on the upper and lower surfaces, and the connecting posts 8 respectively disposed in the through holes 51 of the wooden board 5. The production method can be formed by integral bonding, and the thickness of the template 4 having the upper and lower plastic layers 6, 7 is the same as that of the general template 4.

The template 4 of the present invention combines the through holes 51 of the wooden board 5 with the upper and lower plastic layers 6, 7 and the connecting columns 8 and the plastic frame 9 to strengthen the structure of the template 4 and increase the service life. The template 4 of the invention is anti-collision, scratch-proof and does not absorb muddy water, and can be reused at least 40 times in the concrete grouting operation, but the disassembled template 4 is sometimes caused by the staff directly thrown on the floor. The upper and lower plastic layers 6, 7 directly hit the ground or the sides of the plastic frame 9 directly hit the ground, so that the upper and lower plastic layers 6, 7 are not easily separated from the surface of the wooden board 5 due to the connection of the connecting columns 8. The side edges of the plastic frame 9 are not easily warped or deformed by external force.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the scope of the patents of the present invention. Other equivalents of the patent spirit of the present invention are all within the scope of the invention.
