Description

Technical Field

[0001] The utility model belongs to the technical field of supporting devices for wallboard molds, and in particular relates to a template supporting structure. Background Art

[0002] In building construction, casting wall panels requires the vertical arrangement of at least one set of horizontally opposite formworks to form an inner cavity on the inner side of the formworks for pouring concrete to solidify and form wall panels; a supporting structure is provided on the outer side of the formworks to prevent the formworks from moving outwards due to pressure during the pouring process, thereby keeping the inner cavity for pouring stable.

[0003] At present, the common support structure is to set horizontal back ribs and vertical back ribs on the outside of the template, and then set tension screws that penetrate the two templates and the horizontal back ribs on both sides, so that the support structure remains stable through the force of the horizontal back ribs, such as a template system disclosed in Chinese patent CN218234328U. However, when the mold is removed after pouring, since the two ends of the tension screw protrude from the wall surfaces on both sides, it is necessary to pull out the tension screws and backfill and repair the screw holes, resulting in complicated procedures and troublesome operations. Moreover, for wall panels that need to wade through water, even if the wall surface after the screw holes are repaired is waterproofed, it is difficult to meet the required waterproof performance. There are also support structures that do not use tension bolts, such as a steel back rib template combined support structure for housing construction that is easy to adjust disclosed in Chinese patent CN220395195U, and a cast-in-place wall column template reinforcement disclosed in CN219281268U. However, this support structure requires a number of plates to be connected in sequence horizontally and end to end to surround and tighten all the templates, which is difficult to apply to the situation where the two ends of the wall panel to be poured are connected to other building structures.

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0018] Example:

[0019] See also Figure 1 A formwork support structure comprises two formworks 2 erected on a concrete cushion layer 1, the two formworks 2 being arranged opposite to each other transversely, and a horizontal back rib 3, a vertical back rib 4 and a plug-in column 5 are arranged on the outer side of the formwork 2, the horizontal back rib 3 is located between the formwork 2 and the vertical back rib 4, one horizontal side of the horizontal back rib 3 is fixedly connected to the outer side surface of the formwork 2, and the other horizontal side of the horizontal back rib 3 is abutted against the vertical back rib 4, the plug-in column 5 is arranged vertically and the lower end is buried and fixed in the concrete cushion layer 1, the vertical back rib 4 is tubular and the upper end of the plug-in column 5 extends into the vertical back rib 4; the vertical back ribs 4 on the outer sides of the two formworks 2 are opposite to each other in pairs, and a cross bar 6 is abutted against the upper ends of the two opposite vertical back ribs 4, and the cross bar 6 has two sockets corresponding to the two opposite vertical back ribs 4 respectively, and a plug pin 7 is arranged in the socket and the lower end of the plug pin 7 extends into the vertical back rib 4.

[0020] In this embodiment, the concrete cushion layer 1 is a basic structure for pouring wall panels. The horizontal back ribs 3 are wooden strips arranged horizontally along the outer side of the template 2. Two horizontal back ribs 3 are arranged vertically at intervals on the outer side of each template 2. The horizontal back ribs 3 are fixed to the outer side of the template 2 by steel nails. The vertical back ribs 4 are vertically arranged steel pipes. The plug-in columns 5 are vertically arranged steel bars. After the construction is completed, the protruding parts are pulled out or sawed off. During construction, a steel cage is first arranged on the concrete cushion layer 1, and then the template 2 is arranged outside the steel cage. In order to avoid the template 2 from moving inward during the installation of the supporting structure before pouring, the two templates 2 facing each other are An inner support strip is provided in between; then the vertical back ribs 4 of the horizontal back ribs 3 are arranged in sequence on the outside of the template 2. When the vertical back ribs 4 are arranged, the vertical back ribs 4 are first erected on the concrete cushion layer 1 and the plug-in column 5 is inserted into its lower end, and then a cross bar 6 is arranged at the upper ends of the two opposite vertical back ribs 4 and a latch 7 is inserted to lock the upper ends of the vertical back ribs 4; two horizontally opposite templates 2 are a group. For wall panels to be cast with a longer length, multiple groups of templates 2 can be connected in sequence. End plates can be set at both ends according to the construction scene or connected with other building structures, so that a circumferentially closed inner cavity is formed on the inner side of the template 2 for the poured concrete to condense to form a wall panel.

[0021] The template support structure of the utility model sets the horizontal back rib 3 between the template 2 and the vertical back rib 4, sets the plug-in column 5 on the concrete cushion layer 1, and the plug-in column 5 is inserted into the lower end of the vertical back rib 4, sets a cross bar 6 above the two vertical back ribs 4, and sets a pin 7 inserted into the upper end of the vertical back rib 4 on the cross bar 6, so as to limit the lateral movement of the lower and upper ends of the vertical back rib 4, so as to avoid the template 2 from moving outwards during the pouring process by the force of the vertical back rib 4; the template support structure does not need to use tension bolts, is simple to install, and after the construction is completed, only the pin 7 needs to be pulled out to quickly remove the template, and it will not cause damage to the poured wall panel, which is beneficial to improving the quality of the poured wall panel; it can effectively solve the problems of the existing template support structure that is troublesome to construct and use and has poor applicability, and achieves the effect of reducing the difficulty of construction and improving the construction efficiency.

[0022] See also Figure 1 The side of the inner wall of the vertical back rib 4 close to the template 2 abuts against the plug-in column 5, and the pin 7 abuts against the side of the inner wall of the hole away from the template 2 and the side of the inner wall of the vertical back rib 4 close to the template 2 respectively; in this way, the upper and lower ends of the vertical back rib are in abutment during installation, so that the distance between the two templates can be kept completely consistent before and after pouring, which is beneficial to improving construction accuracy and quality.

[0023] See also Figure 1 The insertion hole is a long hole extending along the length direction of the cross bar 6. In the length direction of the insertion hole, the size of the pin 7 decreases from top to bottom, and the size of the insertion hole is larger than the lower end of the pin 7 and smaller than the upper end of the pin 7; the upper end of the pin 7 is located above the cross bar 6; in this way, the size of the lower end of the pin 7 is smaller than the insertion hole, which is convenient for inserting the pin 7 into the insertion hole from top to bottom, and the size of the upper end of the pin 7 is larger than the insertion hole, so that the pin 7 will not fall into the vertical back rib 4 after being inserted into the insertion hole.

[0024] See also Figure 1 In order to facilitate the insertion of the plug 7 and make it abut against the inner wall of the vertical back rib 4, it is designed that in the length direction of the insertion hole, the side of the plug 7 close to the template 2 is a vertical plane, and the side away from the plug 7 forms an acute angle with the vertical plane, that is, the cross-section of the plug 7 in the length direction of the horizontal back rib 3 is a right triangle with the tip facing downward, and the hypotenuse is on the side away from the template 2; in this way, when the plug 7 is inserted into the insertion hole and partially inserted into the upper end of the vertical back rib 4, as the plug 7 is pressed down, the plug 7 moves as a whole to the side of the template 2 and gradually abuts against the inner wall of the vertical back rib 4.

[0025] See also Figure 1 , the spacing between the two insertion holes on the cross bar 6 matches the spacing between the two opposite vertical back ribs; in this way, after the latch 7 is inserted into place, the entire vertical plane of the side of the latch 7 close to the template 2 abuts against the inner wall of the vertical back rib 4, making the abutment limit more stable and reliable.

[0026] See also Figure 1The design of the latch 7 is plate-shaped and the thickness thereof matches the width of the insertion hole. This can prevent the latch 7 from shaking during the insertion process and after being inserted into place, which is beneficial to reducing the difficulty of installation and improving the stability of the template support structure.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the utility model without departing from the purpose and scope of the technical solution of the utility model should be included in the scope of the claims of the utility model.
