[0042] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Example 1

[0044] like Figure 1-Figure 5 As shown together, the window sill top casting template proposed in this embodiment can be used as a casting template for the window sill top, and can also be used as a casting template for the secondary structure ring beam of a building.

[0045] The window sill top casting template may include a pair of templates 1 and a template fixing assembly 2. The pair of templates 1 is used to block the outer molds formed on both sides of the window sill 8 for casting, and the template fixing assembly 2 is used to stably fix the pair of templates 1 on both sides of the window sill 8.

[0046] The template 1 may include a rectangular plate 11, which may be a lightweight profile. The length of the rectangular plate 11 may be determined according to the length of the window sill or the length of the capping to be cast, and the width is higher than the height of the capping to be cast, so as to ensure that the lower part of a pair of templates 1 can be stably clamped on both sides of the window sill. Back ribs 12 are evenly arranged on the back side of the rectangular plate 11 along the width direction. The back ribs 12 may be a rod with a rectangular cross section, the rod is the same length as the rectangular plate 11, and the width direction of the cross section of the back ribs 12 is connected to the rectangular plate 11. The spacing of the back ribs 12 is determined according to the width of the template 1. Generally, three back ribs 12 are arranged, and the three back ribs 12 are respectively close to the upper edge, the middle part and the lower edge of the template 1. The rectangular plate 11 and the back ribs 12 are integrally formed.

[0047] The template fixing assembly 2 may include a pair of clamping members 21, and the clamping members 21 may include a reinforcing rod 211 and a clamping groove 212 arranged along the reinforcing rod 211 and corresponding to the back rib 12. The clamping members 21 are evenly arranged on the back of the template 1, and the back rib 12 is clamped with the corresponding clamping groove 212. The front sides of a pair of templates 1 are arranged opposite to each other and the back rib 12 is respectively clamped in the corresponding clamping groove 212. The upper ends of the reinforcing rods 211 of the pair of clamping members 21 are connected together by fasteners 22. The front side is smooth and flat for pouring concrete.

[0048] Several pairs of clamping members 21 are respectively connected to a pair of templates 1, and the slots 212 are used to clamp together with the back ribs 12, so that the template 1 and the clamping members 21 form a whole. The number of clamping members 21 is determined according to the length of the template 1, and the spacing between the pairs of clamping members 21 must be ensured. After being connected by fasteners 22, several pairs of clamping members 21 can push the template 1 in a balanced manner on the back of a pair of templates 1.

[0049] In a specific embodiment of the present invention, in order to firmly clamp, the clamping slot 212 includes two parallel cube blocks 2121 arranged in parallel up and down, and the reinforcing rod 211 is vertically connected to the cube blocks 2121 to form a plurality of clamping slots 212. The spacing between the two cube blocks 2121 of each clamping slot 212 is the same as the thickness of the back rib 12, the length of the cube block 2121 is the same as the width of the back rib 12, and the width can be the same as the width of the reinforcing rod 211, and the contact area is required to ensure that the clamping is firm and stable. The clamping slot 212 of the clamping member 21 is just clamped in the back rib 12, and the clamping position of the paired clamping members 21 can be adjusted by sliding as needed.

[0050] In a specific embodiment of the present invention, in order to further secure the clamping, grooves 13 are respectively provided on the upper and lower surfaces of the back rib 12 along the length direction of the back rib 12, and the grooves 13 can be shallow grooves with a square cross section, and convex rods 213 corresponding to the grooves 13 are provided on the inner side surfaces of the two cube blocks 2121 of each clamping groove 212, and the cross section of the convex rods 213 is adapted to the cross section of the groove 13. When the back rib 12 is clamped in the clamping groove 212, the grooves 13 and the corresponding convex rods 213 are clamped, so that the connection between the template 1 and the clamping member 21 can be more stable.

[0051] When the template 1 is connected to the clamping member 21 , the back rib 12 can be inserted into one side of the slot 212 .

[0052] In a specific embodiment of the present invention, in order to further secure the clamping, the number of grooves 13 on the upper and lower surfaces of the back rib 12 is two, and the two grooves 13 have an appropriate spacing, and two convex rods 213 corresponding to the grooves 13 are provided on the opposite sides of the two cube blocks 2121 of each clamping slot 212. When each back rib 12 and the clamping slot 212 are clamped, they are further securely connected through the four pairs of grooves 13 and convex rods 213. The reinforcement rod 211 and the clamping slot 212 are integrally formed.

[0053] In a specific embodiment of the present invention, in order to facilitate the connection of the fastener 22, the upper end of the reinforcing rod 211 is higher than the upper edge of the template 1, and the lower end of the reinforcing rod 211 is substantially flush with the lower edge of the template 1. After the clamp is connected to the template, the upper end of the reinforcing rod 211 is higher than the template 1 for connecting the fastener 22, and the height of the fastener 22 is convenient for pouring and vibrating. The clamp 21 is evenly connected to the back of the template 1, and the clamping force on the template 1 is balanced.

[0054] In a specific embodiment of the present invention, in order to vertically clamp the clamping member 21, the fastener 22 may include an upper screw hole 221 and a lower screw hole 222 provided on the reinforcement rod 211, the upper thread is located at the upper end of the reinforcement rod 211, and the lower screw hole 222 is located above the template 1. The reinforcement rods of the paired clamping members 21 correspond to each other, and the upper connecting bolts 223 are screwed together in the upper screw holes 221 of the reinforcement rods 211 of the paired clamping members 21, and the lower connecting bolts 224 are screwed together in the lower screw holes 222 of the reinforcement rods 211 of the paired clamping members 21.

[0055] Each pair of reinforcing rods 211 is connected by two sets of bolts, upper connecting bolts 223 and lower connecting bolts 224, which can keep the reinforcing rods 211 vertical and firmly connected. The upper screw holes 221 and the lower screw holes 222 have the same specifications, and the upper connecting bolts 223 and the lower connecting bolts 224 have the same specifications. The upper screw holes 221 and the lower screw holes 222 can be screw holes drilled on the reinforcing rods 211.

[0056] Before connecting the fastener 22, the template clamping assembly on one side can be separated from the upper / lower connecting bolts. When the two templates 1 are both close to the two sides of the window sill, the upper / lower connecting bolts are screwed into the upper / lower screw holes of the previously separated template clamping assembly, and each pair of clamps are connected by the upper / lower connecting bolts until they are tightened.

[0057] In a specific embodiment of the present invention, in order to form the fastener 22 and the clamping member 21 as a whole and prevent them from being lost, a nut 225 is provided at the same end of the upper connecting bolt 223 and the lower connecting bolt 224, and a nut 226 is welded at the middle of the upper connecting bolt 223 and the lower connecting bolt 224. By rotating the upper / lower connecting bolts, only one side of the clamping member can be separated from the upper / lower connecting bolts, and the clamping member 21 on the other side is not separated from the upper / lower connecting bolts due to the restriction of the nut 226 and the nut 225.

[0058] The two clamping member template assemblies can be pushed tightly on both sides of the window sill respectively, and then the upper / lower connecting bolts are rotated through the upper / lower screw holes on the separated clamping members 21 until the two clamping member template assemblies are stably clamped on both sides of the window sill.

[0059] In a specific embodiment of the present invention, in order to accurately grasp the pouring thickness, scales 3 are provided on the width edges of both ends of the rectangular plate 11, and an upper plate 4 is provided along the edge of the rectangular plate 11 adjacent to the fastener 22, and the 0 scale line of the scale 3 is located on the lower side of the upper plate 4. During pouring, the pouring thickness is accurately controlled by observing the scale 3, so that the thickness of the window sill cap or ring beam is accurate.

[0060] When arranging the clamping part template combination, the scale value of the upper surface of the window sill can be set as the thickness of the top according to the thickness of the window sill top and the ring beam, and the thickness between the upper plate 4 and the window sill is the thickness of the top. The pouring is completed when pouring to the upper plate 4, and the pouring thickness can be correctly controlled. The two upper plates 4 cannot cover the spacing of a pair of templates 1, and should be convenient for pouring. The upper plate 4 can also make the upper surface of the concrete flat. The upper plate 4 is perpendicular to the rectangular plate 11 and is integrally formed.

[0061] In a specific embodiment of the present invention, a rubber strip 5 is provided inside the lower edge of the rectangular plate 11. The rubber strip 5 is equal in length to the lower edge and tightly seals the gap between the template 1 and the window sill to prevent concrete from overflowing.

[0062] In order to lengthen the window sill top casting template and make it applicable to the construction of longer ring beams, a bolt hole 6 is provided at one end of the back rib 12 and a bolt rod 7 is provided at the other end, and the central axes of the bolt hole 6 and the bolt rod 7 are in the same straight line. The template 1 can be lengthened by connecting adjacent bolt holes 6 and bolt rods 7, and the clamping piece 21 is clamped on the back of each template 1, so that it can be used for casting of different lengths. The number of bolt holes 6 / bolt rods 7 of each back rib 12 can be two.

[0063] Example 2

[0064] Figure 6 This is a flow chart of a window sill capping casting method according to Example 2 of the present invention;

[0065] like Figure 6 As shown, the window sill capping casting method provided in this embodiment uses the window sill capping casting template of Example 1 to cast the window sill capping or the secondary structure ring beam, comprising the following steps:

[0066] S1: clamp the back ribs 12 of a pair of templates 1 into the corresponding clamping grooves 212 of a pair of clamping members 21 respectively.

[0067] First, separate the connection between the plurality of clamping members 21 and the upper / lower connecting bolts on one side, and clamp the template 1 and the clamping members 21 to form a clamping member template combination.

[0068] S2: A pair of templates 1 are respectively and symmetrically attached to the two sides of the window sill 8, and the distance between the edge of the fastener 22 adjacent to the template 1 and the surface of the window sill 8 is not less than the height of the window sill top to be cast.

[0069] The two clamping templates are symmetrically attached to the two sides of the window sill 8 to be constructed. The height of the template 1 above the window sill 8 is determined according to the construction situation and cannot be lower than the height to be poured. The contact area between the template 1 and the window sill 8 must ensure that the window sill 8 can be stably clamped.

[0070] S3: Connecting the upper ends of the reinforcement rods 211 of the pair of clamping members 21 together through the fasteners 22;

[0071] After the clamping part template assembly is correctly placed, the clamping part template assembly is vertical, and the opposite reinforcing rods 211 of the paired clamping parts 21 are connected by fasteners 22, so that the clamping part template assembly is balanced and vertically attached to the side wall of the window sill. Since the clamping parts 21 are evenly arranged on the outer side of the template 1, after the upper / lower connecting bolts are tightened, the clamping force on the clamping part template assembly is uniform, which can ensure that the template 1 and the window sill 8 are highly parallel, and the top side of the cast window sill is smooth and has good visual quality.

[0072] S4: pouring concrete between a pair of formworks 1.

[0073] After the paired clamping templates are fixed, concrete pouring begins. The thickness of the concrete can be observed through scale 3, and the elevation of the upper surface of the concrete can be easily controlled. After the concrete solidifies, the window sill top casting template is removed. If the ends of the paired clamping templates need to be closed, use wooden boards to seal them.

[0074] The window sill top casting template and method according to the present invention are described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various improvements can be made to the window sill top casting template and method proposed by the present invention without departing from the content of the present invention.
